Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to a pressure relief valve shield, a vehicle tailgate, and a vehicle. Background Technology

[0002] Vehicles are typically equipped with a pressure relief valve, which effectively balances the air pressure inside and outside the vehicle. On some vehicles, the pressure relief valve is located on the tailgate. This design presents the following technical problems:

[0003] like Figure 1 As shown, the pressure relief valve 200 on the tailgate 100 is typically located at the spare tire bracket 300. Although the spare tire bracket 300 and spare tire 400 provide some protection behind the pressure relief valve 200, the extent of their protection is limited, leaving the valve essentially exposed. This negatively impacts the vehicle's appearance. Because the pressure relief valve 200 is exposed, external contaminants such as water and dust can easily enter the vehicle through it. Furthermore, the valve's blades produce a knocking sound when opening and closing, especially when the tailgate is closed. This knocking sound is easily heard by the user, resulting in a poor driving experience. Summary of the Invention

[0004] The purpose of this invention is to provide a pressure relief valve shield, a vehicle tailgate, and a vehicle to mitigate or eliminate at least one of the aforementioned technical problems.

[0005] The present invention discloses a pressure relief valve cover, wherein the pressure relief valve cover is provided with a cover body, the cover body is used to cover the outside of the pressure relief valve and the spare tire bracket on the tailgate of a vehicle, and the cover body is provided with a louver structure for air to enter and exit the inner cavity of the cover body.

[0006] Optionally, the louver structure includes multiple blades arranged at intervals in sequence, with each blade tilted downwards from the inside out.

[0007] Optionally, the multiple blades are arranged at intervals in the vertical direction.

[0008] Optionally, the lower edge of the upper blade in a side view is located outside the upper edge of the lower blade in a side view.

[0009] Optionally, the lower edge of the upper blade in a vertical direction is not higher than the upper edge of the lower blade in a vertical direction.

[0010] Optionally, the louvered structure is provided on the left side wall of the cover, and / or the louvered structure is provided on the right side wall of the cover.

[0011] Optionally, it also includes a base for connection to the vehicle tailgate, with the cover connected to the base.

[0012] The present invention also proposes a vehicle tailgate, including a tailgate body, a pressure relief valve, a spare tire bracket, and a pressure relief valve cover as described in any one of the above. The pressure relief valve and the spare tire bracket are mounted on the tailgate body. The cover of the pressure relief valve cover covers the outside of the pressure relief valve and the spare tire bracket, and the pressure relief valve cover conceals the pressure relief valve and the spare tire bracket.

[0013] Optionally, the air inlet and outlet directions of the louver structure on the pressure relief valve shield are offset from the pressure relief direction of the pressure relief valve.

[0014] The present invention also proposes a vehicle including the vehicle tailgate described in any of the preceding claims.

[0015] The pressure relief valve cover proposed in this invention can conceal the pressure relief valve and spare tire bracket, making the vehicle's appearance more complete and aesthetically pleasing. By incorporating a louvered structure on the pressure relief valve cover, air can smoothly enter and exit the cover, ensuring the normal operation of the pressure relief valve. The well-designed louvered structure effectively prevents water, dust, and other foreign objects from entering the vehicle through the pressure relief valve. By offsetting the air intake and exhaust directions of the louvered structure from the pressure relief valve's discharge direction, the impact noise generated by the opening and closing of the valve's blades can be blocked.

Detailed Implementation

[0029] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0031] like Figures 5 to 8The diagram illustrates a pressure relief valve shield 4. The shield 4 includes a cover that covers the pressure relief valve and spare tire bracket on the vehicle's tailgate. The cover has louvers 41 that allow air to enter and exit its inner cavity. By providing the cover, the pressure relief valve shield 4 effectively conceals the pressure relief valve and spare tire bracket. The louvers 41 allow air to flow smoothly through the shield 4, ensuring the normal operation of the pressure relief valve. This technical solution, using the pressure relief valve shield 4 with its louvers 41 to conceal the pressure relief valve and spare tire bracket, improves the vehicle's exterior integrity and aesthetics. The louvers 41 not only ensure the normal operation of the pressure relief valve but also prevent water, dust, and other foreign objects from entering the vehicle through the pressure relief valve.

[0032] In some embodiments, such as Figures 5 to 9 As shown, the louver structure 41 includes multiple blades 411 arranged at intervals, with each blade 411 inclined downwards from the inside out. Using this technical solution, an air exchange channel 413 inclined downwards from the inside out can be formed between adjacent blades 411. This reduces the likelihood of water, dust, or other foreign objects from outside the vehicle entering the interior cavity of the hood through this air exchange channel 413, effectively preventing water, dust, and other foreign objects from entering the vehicle through the pressure relief valve.

[0033] Furthermore, in order to improve the effect of preventing water, dust and other foreign objects from entering the pressure relief valve shield 4 through the ventilation channel 413, the multiple blades 411 of the louver structure 41 are arranged at intervals in the vertical direction.

[0034] In some embodiments, such as Figures 5 to 9 As shown, in the louver structure 41, the lower edge 414 of the upper blade 411, when viewed from the side, is located outside the upper edge 415 of the lower blade 411 when viewed from the side. That is, when viewed from above, the lower edge 414 of the upper blade 411 is located further outward than the upper edge 415 of the lower blade 411. Using the above technical solution, the blades 411 are arranged with a certain degree of overlap, and the blades 411 are inclined downwards from the inside out, with the upper part of the lower blade 411 extending a certain distance below the upper blade 411. Figure 10As shown, when the pressure relief valve shield 4 is actually applied to a vehicle, after the water flow 6 reaches the upper blade 411, under the action of gravity, the water flow 6 flows over the lower edge 414 of the upper blade 411 and falls onto the lower blade 411. The water flow 6 on the lower blade 411 continues to flow downwards, and the water flow 6 on the lower blade 411 will not roll over the upper edge 415 of the lower blade 411, so that the interior of the pressure relief valve shield 4 remains waterless, and the water flow 6 will not splash onto the pressure relief valve. The pressure relief valve shield 4 has a good waterproof effect, which can further prevent water, dust and other foreign objects from the outside of the vehicle from entering the pressure relief valve shield 4 through the ventilation channel 413.

[0035] In some embodiments, such as Figures 5 to 9 As shown, in the two adjacent blades 411 of the louver structure 41, the lower edge 414 of the upper blade 411 is not higher in the vertical direction than the upper edge 415 of the lower blade 411. Using the above technical solution, when viewed from the side, the upper blade 411 completely covers the upper edge 415 of the lower blade 411, effectively blocking water, dust, and other foreign objects from outside the vehicle, further preventing these objects from entering the pressure relief valve shield 4 through the ventilation channel 413.

[0036] In practice, an end plate 412 is usually connected between the ends of two adjacent blades 411, and the end plate 412 between the ends of two adjacent blades 411 forms an air exchange channel 413.

[0037] In practical implementation, the cover of the pressure relief valve shield 4 is usually set as a cover-shaped structure with an open front. The cover is usually surrounded by an upper side wall 43, a lower side wall 44, a left side wall 45, a right side wall 46 and a rear side wall 47. Louvered structures 41 can be set on the lower side wall 44, the left side wall 45 and the right side wall 46 of the cover.

[0038] As a preferred example, louvered structures 41 are respectively provided on the left side wall 45 and the right side wall 46 of the cover. With this preferred solution, on the one hand, the louvered structures 41 on the left side wall 45 and the right side wall 46 of the cover allow the air inlet and outlet directions of the louvered structures 41 to be offset from the pressure relief valve located on the rear of the vehicle's tailgate, thus improving the sound insulation effect against the impact noise generated by the opening and closing of the pressure relief valve's blades 411. On the other hand, the louvered structures 41 on the left side wall 45 and the right side wall 46 of the cover effectively prevent water, dust, and other foreign objects from the outside of the vehicle from entering the pressure relief valve shield 4 through the ventilation channel 413.

[0039] In practical implementation, the blades 411 of the louver structure 41 are parallel to each other, and a reasonable spacing is set between each blade 411. An air exchange channel 413 is formed between two adjacent blades 411. The size of the air exchange channel 413 needs to ensure that it can meet the air intake area and air exchange volume required by the pressure relief valve, so as to meet the pressure relief valve's need to balance the air pressure inside and outside the vehicle and ensure that the pressure relief valve's ventilation and pressure reduction functions are normal.

[0040] In specific implementation, in order to meet the requirements of stiffness and strength of louver structure 41, reinforcing ribs 416 can be set between two adjacent blades 411. The reinforcing ribs 416 can maintain the stability of blades 411.

[0041] In some embodiments, the pressure relief valve cover 4 further includes a base 42 for connection to the vehicle tailgate, with the cover body connected to the base 42. The base 42 facilitates the connection between the pressure relief valve cover 4 and the vehicle tailgate. In a specific implementation, the base 42 is provided with a connection structure 49 for connection to the tailgate body 1. The connection structure 49 includes a snap-fit ​​and a positioning clip, which connect to the tailgate body 1, providing convenient assembly and disassembly. More specifically, a mounting bracket can be provided on the base 42, with snap-fits installed on the bracket for engagement with holes on the tailgate sheet metal parts. Clearly, providing the base 42 around the opening of the cover body also enhances the rigidity and strength of the pressure relief valve cover 4.

[0042] In specific implementation, the pressure relief valve cover 4 can be made by injection molding. The cover is surrounded by a rear side wall 47, an upper side wall 43, a lower side wall 44, a left side wall 45 and a right side wall 46. A clearance hole 48 is provided on the rear side wall 47 to avoid the fastening structure of the spare tire 5.

[0043] like Figures 2 to 8 As shown, the present invention also proposes a vehicle tailgate, including a tailgate body 1, a pressure relief valve 2, a spare tire bracket 3, and a pressure relief valve cover 4 as described in any one of the above. The pressure relief valve 2 and the spare tire bracket 3 are respectively installed on the tailgate body 1. The cover of the pressure relief valve cover 4 covers the outside of the pressure relief valve 2 and the spare tire bracket 3, thus concealing the pressure relief valve 2 and the spare tire bracket 3. In a specific implementation, the tailgate body 1 is provided with a ventilation port 11, the pressure relief valve 2 is installed at the ventilation port 11, the spare tire bracket 3 is installed behind the pressure relief valve 2, and the spare tire 5 is located behind the pressure relief valve cover 4. The spare tire 5 is fixedly connected to the spare tire bracket 3 by fasteners.

[0044] In some embodiments, such as Figure 11As shown, the air inlet and outlet directions of the louver structure 41 on the pressure relief valve shield 4 are offset from the pressure relief valve 2's pressure relief direction 7, which improves the blocking effect on the impact noise generated by the opening and closing of the pressure relief valve 2's blades 411. The positional relationship between the air inlet and outlet directions of the louver structure 41 and the pressure relief valve 2's pressure relief direction 7 is offset. The pressure relief valve 2 is located in the middle of the vehicle, and its pressure relief direction 7 typically faces diagonally backward. The louver structure 41 is located on the left and right sides of the pressure relief valve shield 4. Therefore, the noise generated by the opening and closing movement of the pressure relief valve 2's blades 411 does not propagate directly towards the louver structure 41 of the pressure relief valve shield 4, but is blocked by the rear side wall 47 of the pressure relief valve shield 4. This effectively prevents the noise generated by the opening and closing of the blades 411 of this external pressure relief valve 2 from propagating to the user.

[0045] In some embodiments, the spare tire bracket 3 is typically a sheet metal part with process openings or process notches on the left and right sides. The position of the louver structure 41 on the pressure relief valve shield 4 corresponds to the position of the process opening or process notch on the spare tire bracket 3, so that the louver structure 41 on the pressure relief valve shield 4 can better provide sufficient ventilation for the pressure relief valve 2.

[0046] In practice, the assembly sequence of the vehicle tailgate is as follows: first, install the pressure relief valve 2 on the tailgate body 1, then fix the spare tire bracket 3 on the tailgate body 1, then install the pressure relief valve cover 4 on the tailgate body 1, with the cover of the pressure relief valve cover 4 covering the outside of the pressure relief valve 2 and the spare tire bracket 3, and finally fix the spare tire 5 on the spare tire bracket 3.

[0047] The present invention also proposes a vehicle including the vehicle tailgate described in any of the preceding claims.
