Description

Technical Field

[0001] This utility model relates to the field of automotive control switch manufacturing technology, specifically a highly dustproof and waterproof tailgate switch. Background Technology

[0002] With the booming development of the automotive industry, people have higher and higher requirements for the waterproof rating of automotive switches, especially for exposed automotive switches, particularly tailgate switches. Market feedback shows that the traditional method of using plastic parts to squeeze silicone to achieve waterproofing is not good and can only meet low-level waterproofing requirements. The waterproofing effect is not obvious under high pressure, high temperature and low temperature conditions.

[0003] For example, in the patent document with application number 202323357210.X, a car tailgate switch with a dustproof and waterproof structure is disclosed. Specifically, the bottom cover assembly adopts an insert workpiece injection molding process plus a rubber coating process to form the bottom cover frame, the first waterproof pad, the soft rubber chain, the snap-fit ​​frame and the second waterproof pad together, which can reduce the number of parts.

[0004] The above technical solution uses an overmolding process to further enhance the waterproof performance of the product. However, under high pressure and high temperature conditions, the overmolding process does not have strong stability, so the tailgate switch of the car is still very easy to get water in harsh environments. Utility Model Content

[0005] The technical problem solved by this utility model is to address the issue that the existing rubber coating process lacks strong stability, which leads to water easily entering the tailgate of a car.

[0006] This utility model can be achieved through the following technical solution: a highly dustproof and waterproof tailgate switch, including a button and a controller. The button is installed on the second housing assembly. The second housing assembly and the first housing assembly are connected by silicone injection molding. The first housing assembly is fixed on the vehicle frame. A sensing sensor for sensing the position of the second housing assembly is provided on one side of the housing assembly. The sensing sensor and the controller are connected by signal.

[0007] A further technical improvement of this utility model is that a fixing seat is fixed on the outer shell assembly one, and the outer shell assembly two and the fixing seat are slidably connected.

[0008] A further technical improvement of this utility model is that a rebound spring is provided between the fixed base and the outer shell assembly.

[0009] A further technical improvement of this utility model is that a circuit board assembly for integrating sensor signals is fixedly installed at one end of the housing assembly away from the button, and the circuit board assembly is connected to the controller via a wiring harness assembly.

[0010] A further technical improvement of this utility model is that the pressing surface of the button is inclined.

[0011] A further technical improvement of this utility model is that: a button groove is provided at the end of the button away from the pressing surface, and a guide slope for realizing the outflow of water is provided on the button groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This application involves mounting a button on housing assembly two, connecting housing assembly two and housing assembly one via silicone injection molding, and simultaneously fixing housing assembly one to the vehicle frame. When pressure is applied to the button, housing assembly two is moved, causing a certain deformation of the silicone until housing assembly two and the sensor detect each other, thus controlling the tailgate switch. Because of the silicone connection between housing assembly one and housing assembly two, water and dust will not enter housing assembly one and housing assembly two, thus providing strong stability.

[0014] In order to achieve the rebound of the button, the rebound force of the silicone is used as the first rebound force. At the same time, a rebound spring is provided between the fixing seat and the housing assembly. The rebound spring is fixedly installed between the end of the fixing seat and the housing assembly to ensure the rebound function of the button, thereby ensuring the service life and accuracy of the button.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Please see Figure 1-3 As shown, a highly dustproof and waterproof tailgate switch includes a housing assembly 3 and a housing assembly 5. Housing assembly 3 is an assembly directly injection molded with silicone onto a plastic part, and is a silicone vulcanized part, ensuring that water will not flow into the switch body from the bottom. Housing assembly 5 is also an assembly directly injection molded with silicone onto a plastic part, and is a silicone vulcanized part. In the above technical solution, housing assembly 3 and housing assembly 5 are two plastic parts, and housing assembly 3 and housing assembly 5 are injection molded together with silicone, making it a liquid silicone injection molded part, which can ensure the waterproofness of the top of the switch.

[0022] This application also includes a button 6, which is an external component mounted on the slider. This application also includes a fixing seat 4, which is slidably connected to the slider. The fixing seat 4 provides guidance for pressing the switch and ensures that the switch is pressed normally. At the same time, breathable membranes are provided on the housing assembly 3 and the housing assembly 5 to ensure the balance of air pressure inside and outside the sealed space.

[0023] A circuit board assembly 2 is provided on the side of housing assembly 3 away from housing assembly 5. The circuit board assembly 2 is connected to the controller through the wiring harness assembly 1. When button 6 is pressed, a force is applied to the sensing sensor, and the control signal is transmitted through the circuit board assembly 2, then through the wiring harness assembly 1 to the controller, which is used to control the opening and closing of the car tailgate.

[0024] In the above technical solution, the tailgate opening switch structure of this application is characterized by the fact that the outer shell assembly 3 and the outer shell assembly 5 are injected with silicone onto the plastic parts. Unlike the traditional extrusion waterproofing of switches, the one-piece molded assembly can ensure that the inside of the switch is relatively sealed. Moreover, after applying this technology, market feedback shows that the problem of water ingress into the switch has been greatly reduced, which proves the reliability of this technology.

[0025] As a further embodiment of this application, multiple housing assemblies can be injection molded together with silicone to form a relatively closed assembly, which updates the traditional extrusion waterproofing of plastic parts and silicone to injection molding of plastic parts and silicone together, thus solving the waterproofing problem.

[0026] As a further embodiment of this application, the pressing surface of button 6 is inclined, and a button groove 7 is provided on the side of button 6 away from the pressing surface. A guide slope 8 is provided on the button groove 7. That is, when water falls on the pressing surface of button 6 during use, the shape of button 6 directly guides the water to fall. At the same time, the presence of button groove 7 can reduce the splashing of water on button 6. If the water cup remains on button groove 7, it will be guided by the guide slope 8 to discharge, reducing the water storage on the tailgate switch, thereby ensuring the high waterproof function of the tailgate switch. In this application, the outer shell assembly 1 3 and outer shell assembly 2 5 are injection molded together with silicone, so that when button 6 is pressed, outer shell assembly 2 5 and outer shell assembly 1 3 move relative to each other. At this time, the silicone will deform to a certain extent. Then outer shell assembly 2 5 moves to the sensing position and sends a signal for tailgate switch. During this process, dust and water cannot pass through outer shell assembly 2 5 and enter the interior of outer shell assembly 1 3, so as to ensure the waterproof function of tailgate switch.

[0027] Furthermore, the mounting base 4 is fixedly installed on the outer shell assembly 3, while the outer shell assembly 5 and the mounting base 4 are slidably connected. At the same time, the outer shell assembly 3 and the outer shell assembly 5 are connected together by silicone injection molding. Therefore, when the button 6 is pressed, the outer shell assembly 5 will be pushed to move. At this time, the silicone connection part will deform. However, at this time, the outer shell assembly 5 moves laterally to the end to sense the sensor and realize the tailgate opening and closing sensing function.

[0028] However, in order to achieve the rebound of button 6, the rebound force of silicone is used as the first rebound force. At the same time, a rebound spring is provided between the fixing seat 4 and the housing assembly 5. The rebound spring is fixedly installed between the end of the fixing seat 4 and the housing assembly 5 to ensure the rebound function of button 6.

[0029] In use, the fixing base 4 is fixedly installed on the outer shell assembly 3, while the outer shell assembly 5 and the fixing base 4 are slidably connected. At the same time, the outer shell assembly 3 and the outer shell assembly 5 are connected together by silicone injection molding. Therefore, when the button 6 is pressed, the outer shell assembly 5 will be pushed to move. At this time, the silicone connection part will deform. However, at this time, the outer shell assembly 5 moves laterally to the end to sense the sensor and realize the tailgate opening and closing sensing function.

[0030] The tailgate opening switch structure of this application is characterized by the fact that the outer shell assembly 3 and the outer shell assembly 5 are injected with silicone onto the plastic parts. Unlike the traditional extrusion waterproofing of switches, the one-piece molded assembly can ensure that the inside of the switch is relatively sealed. Moreover, after applying this technology, market feedback shows that the problem of water ingress into the switch has been greatly reduced, which proves the reliability of this technology.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
