Description

Technical Field

[0001] The present invention relates to the technical field of controllers, and in particular to a waterproof device for a tailgate controller of an automobile and a method thereof. Background Art

[0002] In the automotive industry, the tailgate controller is the core component for realizing the automatic opening and closing of the tailgate. Its operating stability directly affects the user experience and driving safety. Traditional tailgate controllers generally have the problem of insufficient waterproof performance. When the vehicle is in a water-related environment such as rainy days or car washes, water vapor can easily invade the internal circuit through the gaps in the controller casing, heat dissipation holes or wiring harness interfaces, causing electronic components to short-circuit and corrode, and then causing the controller to fail or even be damaged. This problem not only increases the vehicle's maintenance cost, but may also cause safety hazards due to abnormal opening or closing of the tailgate. Therefore, the development of a tailgate controller device for automobiles with high-efficiency waterproof performance has become a key technical requirement for improving vehicle reliability and durability.

[0003] However, in actual use, the existing device lacks the necessary sealing mechanism at the data cable interface on the automobile tailgate controller. When the car is washed with a high-pressure water gun, water droplets may enter the controller through the data cable interface, thereby affecting the internal electronic components. Therefore, a waterproof device and method for an automobile tailgate controller are proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that the data line interface on the tailgate controller for an automobile lacks the necessary sealing mechanism. When the automobile is washed with a high-pressure water gun, water droplets may enter the controller through the data line interface, thereby affecting the internal electronic components. A waterproof device and method for a tailgate controller for an automobile are proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A waterproof device for a tailgate controller of an automobile comprises a controller housing, heat dissipation mechanisms are provided on both sides of the controller housing, a joint protective shell is fixedly connected to the rear end of the controller housing, a dehumidification mechanism is provided on the upper part of the joint protective shell, a plurality of connectors are provided inside the joint protective shell, one end of the connector is fixedly connected to a sealed housing, a sealed shell is fixedly connected inside the sealed housing, a second motor is provided inside the sealed shell, a worm is provided at the output end of the second motor, the worm is meshed with a worm wheel, one side of the worm wheel is fixedly connected to a second gear, the second gear is meshed with a first rack, the first rack is fixedly connected to a sealing fixture, the sealing fixture and the connector are slidably connected, one side of the worm is fixedly connected to a first gear, the first gear is meshed with a second rack, one side of the second rack is fixedly connected to a pressure plate, the pressure plate is slidably connected to an inflatable housing, the inflatable housing and the sealed housing are fixedly connected, one side of the inflatable housing is fixedly connected to an inflatable tube, the end of the inflatable tube away from the inflatable housing is fixedly connected to a sealed airbag, and the sealed airbag is fixedly connected inside the connector.

[0007] After the data connector is inserted into the connector, the second motor is started to drive the worm and the first gear to rotate simultaneously. The rotation of the worm drives the worm wheel to rotate, and the rotation of the worm wheel drives the first rack to move, thereby driving the sealing clamp to close the outside of the sealed connector while clamping the data cable. The rotation of the first gear drives the pressure plate to move inside the inflatable shell. The pressure plate moves to compress the gas in the inflatable shell, and the gas enters the sealing airbag through the inflation tube, thereby driving the sealing airbag to expand and fill the gap between the connector and the data head. The inside and outside of the connector are sealed at the same time by the sealing airbag and the sealing clamp to prevent water droplets from entering the controller housing through the connector.

[0008] The above technical solution further includes:

[0009] The sealing shell is fixedly connected to a limiting groove inside, and the limiting groove is slidably connected to a first rack and a second rack.

[0010] The heat dissipation mechanism includes a transmission slot fixedly connected to the upper part of the controller housing, a first motor is provided on one side of the transmission slot, and a heat dissipation component is provided at the output end of the first motor.

[0011] The heat dissipation component includes a threaded rod provided at the output end of the first motor, the threaded rod is threadedly connected to a transmission member, one side of the transmission member is fixedly connected to the transmission rod, and the transmission rod is slidably connected to the controller housing.

[0012] One side of the transmission rod is rotatably connected to a connecting piece, and the side of the connecting piece away from the transmission rod is rotatably connected to a movable heat sink. The movable heat sink is rotatably connected to the controller housing.

[0013] Mounting flanges are fixedly connected on both sides of the controller housing.

[0014] The dehumidification mechanism includes a dehumidification pipe fixedly connected to the upper part of the joint protective shell, an evaporator is arranged inside the dehumidification pipe, a condenser is arranged at the rear end of the evaporator, a compressor is arranged between the evaporator and the condenser, and the dehumidification pipe is connected to both sides of the joint protective shell.

[0015] A fan is provided at the rear end of the condenser.

[0016] A collecting tank is provided at the lower part of the dehumidification pipe near the evaporator, and the collecting tank is communicated with the bottom of the dehumidification pipe.

[0017] A method for using a waterproof device for a tailgate controller of an automobile comprises the following steps:

[0018] Step 1: First, install the controller housing as a whole in the designated position, then connect the data connector and insert it into the connector;

[0019] Step 2: Start the second motor, drive the worm to rotate, and the rotation of the worm drives the first rack to move. The movement of the first rack drives the sealing clamp to move and close the outside of the sealing connector while clamping the data cable.

[0020] Step 3: The second motor drives the worm to rotate, and the first gear rotates at the same time. The rotation of the first gear drives the pressure plate to move in the inflatable housing. The movement of the pressure plate compresses the air inside the inflatable housing. The air enters the sealed airbag through the inflation tube and expands it electrically, thereby filling the gap between the connector and the data head to seal it.

[0021] Step 4: The dehumidification mechanism arranged on the upper part of the connector protective shell regularly absorbs the moist air inside the connector protective shell, and the heat dissipation mechanism arranged on both sides of the controller shell opens when the internal components of the controller shell are working, and closes when the car is washed, thereby sealing both sides of the controller shell.

[0022] The present invention has the following beneficial effects:

[0023] 1. In the present invention, after the data connector is inserted into the connector, the second motor is started to drive the worm and the first gear to rotate simultaneously, and the rotation of the worm can drive the first rack to move, thereby driving the sealing clamp to close, and the data line can be clamped while the outside of the connector is sealed. The rotation of the first gear can drive the pressure plate to move, and the movement of the pressure plate can compress the gas inside the inflatable shell. The gas enters the sealing airbag through the inflation tube and drives the sealing airbag to expand, thereby filling the gap between the data head and the inside of the connector, and sealing the inside of the connector. The combined action of the sealing airbag and the sealing clamp can simultaneously seal the inside and outside of the connector, effectively ensuring the waterproof effect of the connector, and while taking into account waterproofness, it can also play the role of fixing the data connector.

[0024] 2. In the present invention, the heat dissipation effect of the controller housing can be adjusted by controlling the rotation of the movable heat dissipation plates arranged on both sides of the controller housing. When the vehicle body is washed, the movable heat dissipation plates can be controlled to close, thereby effectively sealing both sides of the controller housing, and surface water droplets enter the interior of the controller housing. In addition, the dehumidification mechanism arranged on the upper part of the joint protective shell can regularly dehumidify the interior of the joint protective shell, effectively preventing water droplets from condensing inside the joint protective shell in a humid environment.
