What material is the handle outside the rear door of a car made of
The material of the rear door handle of a car usually varies according to the design and model, but common materials include plastic (such as engineering plastics like ABS, PP, PA, etc.) and metal (such as stainless steel, aluminum alloy).
Youdaoplaceholder0 Plastic material : Many rear door handles are made of engineering plastics such as ABS plastic, PP plastic or PA plastic. These materials feature high strength, wear resistance, impact resistance and resistance to high and low temperatures. Meanwhile, they are lightweight, easy to process and undergo surface treatment (such as spraying or electroplating), which can effectively reduce costs and enhance weather resistance.
For instance, the main body of the handle of some car models is made of plastic, and there may be metal snap-on structures embedded inside to enhance durability.
Youdaoplaceholder0 Metal material : For more upscale models or designs that emphasize durability, the rear door handle may be made of stainless steel or aluminum alloy. Stainless steel has excellent corrosion resistance and wear resistance, making it suitable for harsh weather conditions. Aluminum alloy is lightweight and highly impact-resistant, which can reduce the weight of the vehicle body.
When it comes to different vehicle models, the choice of materials varies by grade: economy cars often use plastic to control costs, while luxury models may adopt metal or alloy materials (such as PC/ABS alloy) to enhance texture and durability.
If your vehicle has a specific model, you can refer to the owner's manual or consult after-sales service for accurate information.
The main function of the handle outside the rear door of a car is to facilitate passengers in opening and closing the door. As a mechanical device of the car door, it is usually linked with the door lock system and the door can be opened or closed manually by pulling.
In addition, depending on the model, the rear door handle may have other functions:
Youdaoplaceholder0 control of electric sliding door : In some MPVS or commercial vehicles (such as the Toyota Gravita), the rear door handle integrates the opening and closing function of the electric sliding door. Passengers can operate the opening or closing of the sliding door through the handle.
Youdaoplaceholder0 Emergency manual door opening : When the vehicle 's electric system malfunctions or the remote key runs out of power, the handle may work in conjunction with the mechanical keyhole to achieve emergency door opening, ensuring that passengers can manually unlock the door from the outside or inside.
Youdaoplaceholder0 Auxiliary functions : In some designs, the position of the handle can serve as a reference point for adjusting the rearview mirror (for example, by observing the position of the handle in the rearview mirror to optimize the field of view), or integrate reversing assistance functions (such as removing the mechanical key through the handle to assist in judging the distance).
Meanwhile, the outer cover of the handle often serves to protect the handle from wear and corrosion, and enhance the aesthetic appearance of the vehicle.
A broken handle outside the rear door of a car does cause inconvenience. Don't worry. We can analyze the possible causes and solutions step by step.
Possible cause analysis
The failure of the rear door handle is usually caused by the following reasons. You can make a preliminary judgment by referring to the vehicle condition:
Youdaoplaceholder0 Mechanical failure : this is the most common cause. May include:
Youdaoplaceholder0 The internal mechanical structure of the handle is stuck or worn : Long-term use or dust entry may cause the internal parts to move inflexibly.
Youdaoplaceholder0 connection pull wire problem : There is usually a small pull wire connecting the door handle and the lock body. If the pull wire breaks, loosens or wears out, it will cause the handle to fail to unlock effectively.
Youdaoplaceholder0 door lock mechanism failure : Rust, wear or damage to the lock body itself can also cause the handle to fail to drive the lock body.
Youdaoplaceholder0 external factors :
Youdaoplaceholder0 Child lock activated : Some models are equipped with child locks on the rear doors. Once activated, the doors cannot be opened from the outside.
Youdaoplaceholder0 Aging of the sealing rubber strip : The aging and deformation of the sealing rubber strip on the car door may cause excessive force when the door is closed, making it difficult to pull the handle.
Youdaoplaceholder0 Door frame or hinge issues : Minor deformation of the door due to an accident or rusting and loosening of the hinges may also cause the handle to get stuck.
Youdaoplaceholder0 electronic system failure (applicable to models with electric control) :
Youdaoplaceholder0 Electronic control system failure : If the vehicle door opening relies on electronic signals, control module or circuit faults may also cause problems.
Youdaoplaceholder0 Low battery voltage : For electric door locks, insufficient battery voltage may also affect their normal operation.
Self-check and simple handling
Before seeking professional help, you can try some simple inspection and handling methods
Youdaoplaceholder0 Check the child lock : First, confirm if the child lock switch was accidentally touched, which is usually located on the inner side panel of the door.
Youdaoplaceholder0 Try to lubricate : If the handle feels stuck, you can try spraying some dry lubricant (such as WD-40) on the handle shaft and lock body, and then repeatedly operate the handle to see if it can regain flexibility. Youdaoplaceholder0 Note: Avoid using grease with high viscosity such as butter, as it is prone to attracting dust.
Youdaoplaceholder0 Check the appearance : Observe whether there is any obvious damage or looseness on the outside of the handle.
Suggestions for maintenance plan
Depending on the complexity of the problem, you have the following options:
Youdaoplaceholder0 Self-repair : If it's just simple lubrication or tightening of connecting parts and you have some hands-on ability, you can refer to the tutorials on the Internet for operation.
But please note : be careful when removing the door interior panels to avoid scratching the paint or damaging the clips.
Youdaoplaceholder0 Professional repair : If the problem is more complex, such as requiring the replacement of the lock body, pull wire or the entire handle assembly, strongly recommends sending it to a professional repair shop or 4S store .
Professional technicians, with the right tools and experience, can ensure the quality and safety of the repair.
