Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a pressure relief valve shielding component, a vehicle tailgate and a vehicle. Background Art

[0002] Vehicles are usually equipped with a pressure relief valve, which can effectively balance the air pressure inside and outside the vehicle. The pressure relief valve of some vehicles is arranged on the back door. This solution of arranging the pressure relief valve on the back door has the following technical problems: like Figure 1 As shown, the pressure relief valve 200 on the back door 100 is usually arranged at the spare tire bracket 300. Although the spare tire bracket 300 and the spare tire 400 block the pressure relief valve 200, the spare tire bracket 300 and the spare tire 400 have a limited shielding range for the pressure relief valve 200. The pressure relief valve 200 is actually in an exposed state, which will have an adverse effect on the appearance of the vehicle. Since the pressure relief valve 200 is actually in an exposed state, foreign matter such as water and dust outside the vehicle can easily enter the vehicle through the pressure relief valve 200. The blades of the pressure relief valve 200 will produce a knocking sound when opening and closing, especially when the back door is closed, the blades of the pressure relief valve 200 will produce a more obvious knocking sound. Since the pressure relief valve 200 is actually in an exposed state, the knocking sound can be easily heard by the user, causing a bad car experience for the user. Summary of the invention

[0003] The object of the present invention is to provide a pressure relief valve shielding member, a vehicle tailgate and a vehicle to alleviate or eliminate at least one of the above-mentioned technical problems.

DETAILED DESCRIPTION

[0017] The following will describe the embodiments of the present invention 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 contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways 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, not for limiting the scope of protection of the present invention.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0019] like Figures 5 to 8 A pressure relief valve shielding member 4 is shown, and a cover body is provided on the pressure relief valve shielding member 4. The cover body is used to cover the outer side of the pressure relief valve and the spare tire bracket on the back door of the vehicle, and a shutter structure 41 is provided on the cover body for air to enter and exit the inner cavity of the cover body. By providing the cover body, the pressure relief valve shielding member 4 can shield the pressure relief valve and the spare tire bracket. The shutter structure 41 allows air to smoothly enter and exit the pressure relief valve shielding member 4, thereby ensuring the normal operation of the pressure relief valve. By adopting the above-mentioned technical solution, the pressure relief valve and the spare tire bracket are shielded by the pressure relief valve shielding member 4 with the shutter structure 41, which can improve the integrity and aesthetics of the vehicle's appearance. The shutter structure 41 can not only ensure the normal operation of the pressure relief valve, but also prevent foreign matter such as water and dust outside the vehicle from entering the vehicle through the pressure relief valve.

[0020] In some embodiments, Figures 5 to 9 As shown, the shutter structure 41 includes a plurality of blades 411 arranged in sequence at intervals, and the plurality of blades 411 are arranged to be tilted downward from the inside to the outside. By adopting the above technical solution, a ventilation channel 413 tilted downward from the inside to the outside can be formed between two adjacent blades 411, and the possibility of foreign matter such as water and dust outside the vehicle entering the inner cavity of the cover through the ventilation channel 413 is small, thereby effectively preventing foreign matter such as water and dust outside the vehicle from entering the vehicle through the pressure relief valve.

[0021] Furthermore, in order to improve the effect of preventing foreign matter such as water and dust from entering the pressure relief valve shielding member 4 through the ventilation channel 413, the plurality of blades 411 of the louver structure 41 are sequentially arranged at intervals along the up-down direction.

[0022] In some embodiments, Figures 5 to 9 As shown, in two adjacent blades 411 of the louver structure 41, the position of the lower edge 414 of the blade 411 located on the upper side when viewed from the side is outside the position of the upper edge 415 of the blade 411 located on the lower side when viewed from the side. That is to say, when looking down at the pressure relief valve shield 4, the position of the lower edge 414 of the blade 411 located on the upper side of the two adjacent blades 411 is further outside than the position of the upper edge 415 of the blade 411 located on the lower side. With the above-mentioned technical solution, a certain amount of overlap is set between the blades 411, and the blades 411 are tilted downward from the inside to the outside, and the upper part of the blade 411 located on the lower side of the two adjacent blades 411 extends a certain distance below the blade 411 located on the upper side. Fig.10 As shown, when the pressure relief valve shielding member 4 is actually used on a vehicle, after the water flow 6 reaches the upper blade 411, under the action of gravity, the water flow 6 flows through the lower edge 414 of the upper blade 411 and then falls on the lower blade 411. The water flow 6 on the lower blade 411 will continue to flow downward, and the water flow 6 on the lower blade 411 will not turn over the upper edge 415 of the lower blade 411, so that the inside of the pressure relief valve shielding member 4 remains water-free, and the water flow 6 will not splash onto the pressure relief valve. The pressure relief valve shielding member 4 has a good waterproof effect, which can further prevent foreign matter such as water and dust outside the vehicle from entering the pressure relief valve shielding member 4 through the ventilation channel 413.

[0023] In some embodiments, Figures 5 to 9As shown, in the two adjacent blades 411 of the shutter structure 41, the lower edge 414 of the blade 411 located on the upper side is not higher than the upper edge 415 of the blade 411 located on the lower side in the vertical direction. With the above technical solution, when the pressure relief valve shielding member 4 is viewed from the side, the blade 411 located on the upper side of the two blades 411 can completely shield the upper edge 415 of the blade 411 located on the lower side, which can more effectively block foreign matter such as water and dust outside the vehicle, and further prevent foreign matter such as water and dust outside the vehicle from entering the pressure relief valve shielding member 4 through the ventilation channel 413.

[0024] In a specific implementation, an end plate 412 is usually connected between the ends of two adjacent blades 411 , and the two adjacent blades 411 and the end plate 412 between the ends of the two adjacent blades 411 form a ventilation channel 413 .

[0025] In a specific implementation, the cover body of the pressure relief valve shielding member 4 is usually configured as a cover-like structure with an open front side, and the cover body 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. A louver structure 41 can be provided on the lower side wall 44, the left side wall 45 and the right side wall 46 of the cover body.

[0026] As a preferred example, the left side wall 45 and the right side wall 46 of the cover are respectively provided with a louver structure 41. With this preferred solution, on the one hand, the louver structure 41 is respectively provided on the left side wall 45 and the right side wall 46 of the cover, so that the air inlet and outlet directions of the louver structure 41 can be staggered with the pressure relief direction of the pressure relief valve arranged rearward on the back door of the vehicle, which can enhance the barrier effect of the impact sound generated by the opening and closing of the blade 411 of the pressure relief valve. On the other hand, the louver structure 41 arranged on the left side wall 45 and the right side wall 46 of the cover has a good effect of preventing foreign matter such as water and dust outside the vehicle from entering the pressure relief valve shielding member 4 through the ventilation channel 413.

[0027] In a specific implementation, the blades 411 of the louver structure 41 are parallel to each other, and a reasonable spacing is set between the blades 411, and a ventilation channel 413 is formed between two adjacent blades 411. The size of the ventilation channel 413 needs to ensure that the air intake area and ventilation volume required by the pressure relief valve can be achieved, thereby meeting the pressure relief valve's requirement to balance the air pressure inside and outside the vehicle, and ensuring that the ventilation and decompression functions of the pressure relief valve are normal.

[0028] In a specific implementation, in order to meet the requirements of rigidity and strength of the louver structure 41 , a reinforcing rib 416 may be provided between two adjacent blades 411 , and the reinforcing rib 416 can maintain the stability of the blades 411 .

[0029] In some embodiments, the pressure relief valve shielding member 4 also includes a base 42 for connecting to the vehicle back door, and the cover body is connected to the base 42. The base 42 is provided to facilitate the connection between the pressure relief valve shielding member 4 and the vehicle back door. In a specific implementation, a connecting structure 49 for connecting to the back door body 1 is provided on the base 42, and the connecting structure 49 includes a buckle and a positioning card, and is connected to the back door body 1 by means of the buckle and the positioning card, and has the characteristic of convenient disassembly and assembly. More specifically, a clamping seat can be provided on the base 42, and a buckle for clamping with a hole on the back door sheet metal can be installed on the clamping seat. Obviously, providing a base 42 on the open periphery of the cover body can also improve the rigidity and strength of the pressure relief valve shielding member 4.

[0030] In specific implementation, the pressure relief valve shielding member 4 can be made by one-piece injection molding. The cover body 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. An avoidance hole 48 for avoiding the fastening structure of the spare tire 5 is provided on the rear side wall 47.

[0031] like Figures 2 to 8 As shown, the present invention also proposes a vehicle tailgate, comprising a tailgate body 1, a pressure relief valve 2, a spare tire bracket 3 and the pressure relief valve shielding member 4 described in any one of the above items, the pressure relief valve 2 and the spare tire bracket 3 are respectively mounted on the tailgate body 1, the cover body of the pressure relief valve shielding member 4 covers the outside of the pressure relief valve 2 and the spare tire bracket 3, and the pressure relief valve shielding member 4 shields the pressure relief valve 2 and the spare tire bracket 3. In a specific implementation, a ventilation port 11 is provided on the tailgate body 1, the pressure relief valve 2 is mounted at the ventilation port 11, the spare tire bracket 3 is mounted at the rear side of the pressure relief valve 2, the spare tire 5 is located at the rear side of the pressure relief valve shielding member 4, and the spare tire 5 is fixedly connected to the spare tire bracket 3 by a fastener.

[0032] In some embodiments, Fig.11 As shown, the air inlet and outlet directions of the louver structure 41 on the pressure relief valve shielding member 4 and the pressure relief direction 7 of the pressure relief valve 2 are staggered, which can enhance the barrier effect on the impact sound generated by the opening and closing of the blades 411 of the pressure relief valve 2. The positional relationship between the air inlet and outlet directions of the louver structure 41 and the pressure relief direction 7 of the pressure relief valve 2 is staggered. The pressure relief valve 2 is arranged in the middle position of the whole vehicle. The pressure relief direction 7 of the pressure relief valve 2 is usually toward the oblique rear. The louver structure 41 is arranged on the left and right sides of the pressure relief valve shielding member 4. Therefore, the noise generated by the opening and closing movement of the blades 411 of the pressure relief valve 2 is not transmitted directly to the louver structure 41 of the pressure relief valve shielding member 4, but is blocked by the rear side wall 47 of the pressure relief valve shielding member 4. Therefore, the noise generated by the opening and closing of the blades 411 of the external pressure relief valve 2 can be effectively blocked from being transmitted to the user.

[0033] In some embodiments, the spare tire bracket 3 is generally a sheet metal part, and has a process opening or a process notch on the left and right sides of the spare tire bracket 3. The position of the louver structure 41 on the pressure relief valve shielding part 4 is set to correspond to the position of the process opening or the process notch on the spare tire bracket 3, so that the louver structure 41 on the pressure relief valve shielding part 4 can better provide sufficient ventilation volume for the pressure relief valve 2.

[0034] In a specific implementation, the assembly sequence of the above-mentioned vehicle tailgate is: first install the pressure relief valve 2 on the tailgate body 1, then fix the spare tire bracket 3 on the tailgate body 1, and then install the pressure relief valve shielding member 4 on the tailgate body 1, with the cover body of the pressure relief valve shielding member 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.

[0035] The present invention also provides a vehicle, comprising any one of the vehicle tailgates described above.
