Technical Field

[0001] This utility model relates to the field of tailgate electrical control boxes, specifically to a water-proof and water-accumulation-proof automotive tailgate electrical control box. Background Technology

[0002] Currently, trucks have a cargo box with a tailgate at the rear. The tailgate can be opened downwards to a roughly horizontal position, then lowered. After loading, the tailgate can be raised for easy loading and unloading. The tailgate's operation is controlled by several buttons. An electrical control box is installed at the rear of the cargo box, housing the control buttons. Wiring holes are formed on the rear wall of the control box, through which wires are led out. In practical applications, the control box is inevitably exposed to storms. Although it has a cover, external water (such as splashing water from the road or rainwater) can easily reach the wiring holes along the cargo box and the rear wall. This can cause water to accumulate inside the control box, leading to leakage and damage to the control buttons and other electrically powered components. Therefore, the existing tailgate electrical control box has poor waterproofing performance and needs improvement. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a water-proof and water-accumulation-proof vehicle tailgate electrical control box with good waterproof performance.

[0004] The objective of this utility model is achieved through the following technical solution.

Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] This utility model relates to a water-proof and water-accumulation-proof automotive tailgate electrical control box, such as... Figures 1 to 4 As shown, the box includes a housing 1, with a box opening 100 formed on the front side of the housing 1. That is, the housing 1 is designed to open forward. A box cover 2 is provided corresponding to the box opening 100. The box cover 2 is hinged to the housing 1, meaning that the box cover 2 is used to close or open the box opening 100. Specifically, wing plates are formed at both ends of the box cover 2, and the wing plates are located on the outside of the housing 1. Figure 5 As shown, hinge shafts 12 are formed approximately at the center of the left and right sides of the housing 1. The wing plates are hinged to the housing 1 via the corresponding hinge shafts 12. The housing cover 2 can swing upward to open or downward to close. Figure 2 As shown, when the lid 2 is in the closed state, the lid 2 covers the front side of the opening 100. Figure 4 and Figure 5As shown, the interior of the box 1 forms a cavity 10, and a lower wall panel 11 is formed at the bottom of the box 1. Specifically, the box 1 also includes a left wall panel 15, a right wall panel 16, an upper wall panel 17, and a rear wall panel 104. Thus, the left wall panel 15, right wall panel 16, upper wall panel 17, rear wall panel 104, and lower wall panel 11 form a rectangular frame structure with a front opening. The box cover 2 is hinged to the front opening of the box 1. In this utility model, the lower wall panel 11 has a wire hole 101, which can be understood as being formed at the bottom of the box 1 and communicating with the cavity 10. A power control device is provided inside the cavity 10, specifically mounted on a control board 99. The power control device is electrically connected to a wire, which is led out to the outside of the box 1 through the wire hole 101. For this electrical control box, the box body 1 is generally connected to the carriage or vehicle frame through the rear wall panel 104. The rear wall panel 104 can be connected to the carriage by bolts. In special installation cases, the box body can also be mounted on the frame by the lower wall panel 11.

[0023] Because the wiring hole 101 is formed on the lower wall plate 11, meaning that the wiring hole 101 is downward-facing, it is difficult for external water to fall directly into the wiring hole 101. Even if external water flows down the outer wall of the housing 1, it will fall away from the lower wall plate 11 due to gravity before reaching the wiring hole 101. If a small amount of water flows to the wiring hole 101, it will not flow back upward into the wiring hole 101 due to gravity, thus preventing water from entering the housing 10. Even if water seeps into the housing 10 under special circumstances, because the wiring hole 101 is formed on the lower wall plate 11, the water in the housing 10 can also drain out through the wiring hole 101, preventing a large amount of water from accumulating in the housing 10 and causing the aforementioned electrical control devices to come into contact with water. Therefore, the waterproof performance of the automotive tailgate electrical control box of this utility model is good, thereby preventing the electronic components in the housing 1 from malfunctioning or being damaged due to water immersion.

[0024] Furthermore, such as Figure 1 As shown, the wire hole 101 is located at the rear of the lower wall panel 11. Since the rear wall panel 104 is attached to and connected to the carriage, the wire hole 101 is close to the carriage, so the wire led out from the wire hole 101 can reach the carriage in a shorter distance.

[0025] Furthermore, such as Figure 2 As shown, the lower wall panel 11 is inclined with a lower front and a higher back. Therefore, under special circumstances, the water entering the chamber 10 will flow forward to the opening 100 due to gravity because of the inclination of the lower wall panel 11. Thus, the water in the chamber 10 can be easily discharged through the opening 100. A water leakage gap can be formed at the lower end of the control plate 99.

[0026] In some embodiments, such as Figure 6As shown, the lower wall panel 11 has a low position 110, and the wire hole 101 is formed in the low position 110. That is to say, the low position 100 is the recessed part of the lower wall panel 11 (relative to the four edges of the lower wall panel 11). Therefore, under special circumstances, the water entering the box cavity 10 flows down to the lower wall panel 11, and then the water converges and flows to the low position 110. After that, the water is quickly discharged downward through the wire hole 101, thereby avoiding water accumulation in the box cavity 10.

[0027] Furthermore, such as Figures 1 to 5 As shown, the automotive tailgate electrical control box of this utility model also includes a locking assembly 3. A lower protruding plate 102 is formed at the lower edge of the box opening 100, and an outer protruding edge 201 is formed at the lower end of the box cover 2. The locking assembly 3 includes a swingable locking arm 32. One end of the locking arm 32 is connected to the box body 1, and the corresponding other end of the locking arm 32 forms a locking hook portion 321. When the box cover 2 is in the closed state, as... Figure 3 As shown, the outer protruding edge 201 is attached to the front side of the lower protruding plate 102, and the locking hook 321 engages with the outer protruding edge 201. Specifically, the outer protruding edge 201 is clamped between the locking hook 321 and the lower protruding plate 102, thereby locking the lid 2 and preventing it from swinging open. When it is necessary to open the lid 2, the locking arm 32 is swung by hand to disengage the locking hook 321 from the outer protruding edge 201, and then the lid 2 is swung upwards by hand to open. When the tailgate is not in use, the lid 2 can be locked in the closed position by the locking assembly 3, which can prevent the lid 2 from being blown open in windy weather.

[0028] Furthermore, such as Figures 3 to 5 As shown, the locking assembly 3 includes a support 31 and a handle 33. The support 31 is installed on the lower side of the lower wall plate 11. Specifically, the lower wall plate 11 has a lower protrusion 111. A screw passes through the lower protrusion 111 from top to bottom and is screwed onto the support 31. Figure 3As shown, the support 31 is hinged to the front end of the handle 33 via the handle hinge shaft 34, and the rear end of the locking arm 32 is hinged to the handle 33 via the locking arm hinge shaft 35. When the locking assembly 3 is in the locked state, the outer protruding edge 201 is clamped between the locking hook part 321 and the lower protruding plate 102, so there is a contact position between the locking hook part 321 and the outer protruding edge 201. In the front-back direction, the handle hinge shaft 34 is located between the locking arm hinge shaft 35 and the locking hook part 321. When it is necessary to unlock the latch assembly 3, swing the handle 33 downward with your finger so that the locking arm hinge shaft 35 swings to the line connecting the contact position and the handle hinge shaft 34. During this process, the locking hook 321 further hooks and presses the outer protrusion 201 backward. After the locking arm hinge shaft 35 moves downward past the line connecting the contact position and the handle hinge shaft 34, the clamping pressure of the locking hook 321 on the outer protrusion 201 decreases, and then the locking hook 321 releases the outer protrusion 201. Moreover, since the locking arm hinge shaft 35 swings forward and downward, the locking arm 32 moves forward. Then the locking arm 32 can easily swing downward and disengage from the corresponding position of the outer protrusion 201, and the lid 2 can be opened by hand by swinging it upward. When it is necessary to lock the lid 2 in the closed position, first close the lid 2, then manually move the locking arm 32 upwards so that the locking hook 321 abuts against the front side of the outer protrusion 201. Then, swing the handle 33 upwards, causing the locking arm hinge shaft 35 to move backwards and upwards. The locking arm hinge shaft 35 then pulls the locking arm 32 backwards, causing the locking hook 321 to press against the outer protrusion 201. Afterwards, the locking arm hinge shaft 35 moves upwards past the line connecting the contact point and the handle hinge shaft 34, at which point the latch assembly 3 is in the locked state. The structure of the latch assembly 3 makes locking and unlocking reliable and convenient.

[0029] Furthermore, such as Figure 4 As shown, a front locking hole 2011 is formed on the outer convex edge 201, and a rear locking hole 1021 is formed on the lower convex plate 102, as... Figure 1 As shown, when the trunk lid 2 is closed, the front lock hole 2011 and the rear lock hole 1021 are aligned and connected. A lock can be passed through both the front and rear lock holes 2011 to lock the trunk lid 2. A key is required to open the lock. Combined with the latch assembly 3, the trunk lid 2 achieves a double-locking effect, further preventing unauthorized personnel from operating the vehicle's tailgate. In other words, when the electrical control box is not in use, the lock can be left unused; instead, the trunk lid 2 can be quickly locked or unlocked using only the latch assembly 3.

[0030] Furthermore, such as Figure 4 As shown, a positioning step 103 is formed on the inner wall of the cavity 10. A vertically mounted control plate 99 is installed on the positioning step 103 by corresponding screws. A control button 98 is installed on the control plate 99. The control button 98 is prior art. For example, refer to the "push-button switch" in Chinese Utility Model Patent Publication No. CN201490056U. Figure 2 As shown, the control button 98 is covered with a rubber cover 981. The rear end of the rubber cover 981 is attached to the front side of the control plate 99. Because the rubber cover 981 has soft and elastic properties, when the user presses the rubber cover 981 from front to back, the rubber cover 981 will elastically indent, so that the finger can press the button of the control button 98 through the rubber cover 981. When the finger releases the rubber cover 981, the rubber cover 981 elastically returns to its original position. Since the rubber cover 981 covers the part of the control button 98 that protrudes from the front side of the control plate 99, it prevents water from easily seeping into the gap between the button of the control button 98 and the front housing of the control button 98.
