Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, especially relates to a car glass lifter limiting structure. BACKGROUND

[0002] In modern automobile design, the glass lifter is a key component for opening and closing the vehicle window, and its performance directly affects the driving experience and the service life of the vehicle. The traditional glass lifter limiting mechanism usually adopts a mechanical limiting structure, which limits the position of the bracket through physical contact. However, this design has some significant technical problems.

[0003] Firstly, the existing limiting mechanism cannot detect the limit position of the bracket in real time during the lifting process. This means that when the bracket approaches the limit position, the system cannot timely perceive and take appropriate deceleration measures, resulting in a hard collision between the bracket and the limiting mechanism. This collision not only produces noise, but also may cause mechanical damage to the limiting mechanism and the bracket, affecting their service life.

[0004] Secondly, due to the lack of effective detection and control mechanism, the existing limiting mechanism cannot achieve precise control of the motor. When the bracket approaches the limit position, the motor still runs at full speed until the bracket hits the limiting mechanism. This operating mode not only increases the burden of the motor, but also may cause the motor to overheat or even be damaged.

[0005] In addition, the existing limiting mechanism does not have a buffer function when the bracket stops. When the bracket hits the limiting mechanism, due to the lack of a buffer structure, the impact force is directly transmitted to the bracket and the limiting mechanism, which may easily cause deformation or damage of the parts. This not only affects the normal operation of the vehicle window, but also may cause other safety hazards.

[0006] Therefore, it is necessary to improve the above deficiencies of the prior art. SUMMARY

[0007] The technical problem to be solved by the utility model is to provide a car glass lifter limiting structure to solve the problem of damage to parts and affect the service life due to the hard collision between the bracket and the limiting mechanism when the bracket approaches the limit position in the prior art.

[0008] To achieve the above purpose, the utility model provides the following technical scheme: a car glass lifter limiting structure, comprising a guide rail and a bracket slidingly installed on the guide rail, the guide rail is provided with a guide rail groove on one side, the guide rail groove is provided with a Hall sensor electrically connected with a control system at the upper and lower ends, the bracket is provided with a magnet on the side facing the guide rail, the positions of the magnet and the two Hall sensors are aligned and arranged on the same side in the guide rail groove.

[0009] By installing the Hall sensors at the upper and lower ends of the guide rail groove and setting the magnets on the bracket in alignment with the Hall sensors, the position of the bracket on the guide rail can be detected in real time. When the bracket approaches the maximum or minimum position, the Hall sensor can accurately sense the position change of the magnet and transmit the signal to the control system to realize accurate monitoring of the position of the bracket. When the bracket approaches the limit position, the control system can control the motor to gradually slow down to avoid the bracket generating a large impact force due to inertia, thereby improving the stability and safety of the lifting process and prolonging the service life of the guide rail, the bracket, the motor and other related components.

[0010] The further setting of the above technical solution is that the upper and lower ends of the guide rail groove are each provided with an outwardly extending limiting baffle, and the side of the limiting baffle facing the bracket is provided with a resilient buffer pad. When the bracket moves to the maximum or minimum limit position, the bracket can abut against the buffer pad.

[0011] By adopting the above technical solution, the limiting baffles are extended to the two ends of the guide rail groove to mechanically prevent the bracket from moving excessively and ensure that the bracket does not deviate from the guide rail, thereby providing additional safety protection for the automobile glass lifter. The limiting baffles are provided with resilient buffer pads that can buffer when the bracket contacts the limiting baffles, thereby reducing the impact force generated by the impact, reducing the probability of component damage, reducing the noise generated by the impact, and improving the user experience.

[0012] The further setting of the above technical solution is that the buffer pad is made of rubber material.

[0013] By adopting the above technical solution, the rubber material has good elasticity and energy absorption performance, and can achieve good buffering effect.

[0014] The further setting of the above technical solution is that the upper and lower sides of the bracket are each provided with a limiting slot corresponding in position to the limiting baffle.

[0015] By adopting the above technical solution, the limiting slots are designed in position corresponding to the limiting baffles to ensure that the bracket can be accurately aligned when reaching the limit position, thereby enhancing the fixation of the bracket and preventing the bracket from deviating during the lifting process.

[0016] The further setting of the above technical solution is that the two ends of the limiting slot facing the limiting baffle are rounded or chamfered.

[0017] By adopting the above technical solution, the bracket can be more smoothly clamped into the limiting slot when approaching the limiting baffle, thereby reducing the rigid impact, reducing the impact force, and making the glass lifting process more stable.

[0018] Further setting of the above technical scheme is that the side surface of the bracket at one end in the guide rail groove is provided with a magnet slot, and the magnet is embedded and installed in the magnet slot.

[0019] The above technical scheme makes the magnet not protrude from the side surface of the bracket after installation, avoids interference with the inner wall of the guide rail groove during sliding of the bracket, and ensures smooth movement of the bracket in the guide rail groove.

[0020] The utility model discloses reached beneficial effects are: through hall sensor detection control system can control motor gradually decelerate, avoid the bracket because inertia effect produces excessive impact force, match spacing baffle and buffer pad, further buffer weakens impact force, thereby improve the stability and security of lifting process, and further prolong the service life of guide rail, bracket, motor and other related components.

The limiting baffle plate 12 is extendedly provided at the two ends of the guide rail groove 11, mechanically preventing the bracket 2 from moving excessively and ensuring that the bracket 2 will not be separated from the guide rail 1, thereby providing additional safety protection for the car glass lifter.
