What is the front wiper assembly of a car
Car front wiper assembly IS an IMPORTANT PART of the CAR safety system, through the motor to drive the link mechanism to achieve the reciprocating motion of the wiper arm to ensure the driver 's clear view in rain and snow. Its main components include motor, reducer, four-link mechanism, wiper arm shaft and wiper blade assembly, etc. .
The technical core of the front wiper assembly lies in the efficiency, durability of the motor and its compatibility with the vehicle's electronic system. With the development of autonomous driving technology, wiper systems need to work in conjunction with cameras, sensors and other modules, intelligence and integration have become the direction of industry upgrade .
Structure and working principle
The front wiper assembly drives the reducer through the electric motor, then transmits motion to the wiper arm shaft through the four-link mechanism, and finally drives the wiper blade to scrape off rain, snow and dust from the windshield to ensure clear driving view .
Its working mode includes single-step scraping, intermittent scraping, slow scraping, fast scraping and simultaneous water spray and wash scraping functions .
Industry background and market trends
In the global market, the front wiper is the largest segment, accounting for 86% of the market share. With the development of autonomous driving technology, wiper systems need to work in conjunction with cameras, sensors and other modules, intelligence and integration have become the direction of industry upgrade .
In addition, policy support such as the 14th Five-Year Plan and the Belt and Road Initiative also provides opportunities for industry development .
The core components of the wiper assembly include the following parts:
Core functional components
Youdaoplaceholder0 wiper motor
As the power core, it is responsible for converting electrical energy into mechanical energy to drive the operation of the entire system. It usually includes the motor body, reduction gears and reset switch.
Youdaoplaceholder0 Linkage mechanism
The rotational motion of the motor is converted into the reciprocating swing of the wiper arm through components such as the crank and the swing arm. In some designs, a multi-swing arm structure is adopted to achieve a larger scraping and brushing range.
Youdaoplaceholder0 wiper arm
It is installed on the wiper shaft to fix and drive the wiper blade to move, and is usually connected to the connecting rod mechanism through the drive plate.
Youdaoplaceholder0 Wiper blades
It comes into direct contact with the windshield and is responsible for scraping off water stains and dirt. It needs to be replaced or repaired regularly.
Supporting auxiliary components
Youdaoplaceholder0 Control switch
It is located in the driver's cabin and is used to adjust the working mode of the wiper (such as intermittent gear, fast and slow gear).
Youdaoplaceholder0 Water spray system
It includes a water spray motor and pipelines, and works in conjunction with a wiper to clean stains on the glass surface.
Youdaoplaceholder0 Sealing and wear-resistant structure
For instance, the bushings, sealing rings and wear-resistant gaskets inside the shaft sleeve are used to reduce friction and extend the service life of the connecting rod assembly.
Patent Technology Optimization Direction (Example)
Youdaoplaceholder0 Double-layer swing arm design : Expand the brushing range by arranging the obtuse angles of the first and second swing arms.
Youdaoplaceholder0 Composite bushing scheme : The upper and lower bushings are embedded in layers to improve wear resistance and sealing performance.
The design of the wiper assembly needs to take into account both power transmission efficiency and durability. Different manufacturers may make differentiated improvements to the connecting rod structure or sealing scheme.
Youdaoplaceholder0 Causes and solutions of wiper assembly failure mainly include the following aspects:
Youdaoplaceholder0 Wiper blade problem : Wiper blades may get stuck in the windshield due to aging, wear or dirt, causing the wipers to fail to function properly. The solution is to replace the wiper blades with new ones or have them cleaned and serviced .
Youdaoplaceholder0 wiper motor failure : If you feel hot when touching the wiper motor, it may be a short circuit inside the motor. In addition, loose motor joints can also cause malfunctions. The joints can be reconnected. If the motor is severely damaged, it may need to be replaced .
Youdaoplaceholder0 wiper link problem : The link may be deformed or broken, and loose connection points can also cause problems. If the link is severely damaged, it must be replaced .
Youdaoplaceholder0 Fuse problem : Check if the fuse has blown. If so, replace it in time and make sure the fuse connection point is normal .
Youdaoplaceholder0 Control switch problem : Use a multimeter to test the control switch to see if there is any poor contact or short circuit in the circuit. Replace the new switch if necessary for testing .
Youdaoplaceholder0 Precautions and daily maintenance recommendations :
Youdaoplaceholder0 Regular checks : Regularly check the wiper blades, motor, connecting rods and fuses to ensure that all parts work properly.
Youdaoplaceholder0 Cleaning and Maintenance : Keep the wiper blades clean to prevent jamming due to dirt.
Youdaoplaceholder0 Lubrication maintenance : Properly lubricate the connection parts to reduce mechanical resistance.
Youdaoplaceholder0 Replacement cycle : Replace the wiper blades and motor regularly according to usage to prevent failure due to aging or wear.
