[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] Combination Figure 1 and Figure 2 According to an embodiment of the utility model, the back door 100 of the vehicle includes: a back door inner panel 110, which is provided with a mounting position 111; a vibration reduction assembly 120, which includes a vibration reduction bracket 121, a vibration reduction block 122 and a vibration reduction connecting member 123, the vibration reduction bracket 121 is installed at the mounting position 111, and the vibration reduction bracket 121 is provided with a mounting opening 1211 which is set through in the X direction of the vehicle, the vibration reduction block 122 is set in the mounting opening 1211, and the vibration reduction connecting member 123 is used to connect the vibration reduction block 122 and the vibration reduction bracket 121, and suspend the vibration reduction block 122 in the mounting opening 1211.

[0034] Specifically, the vibration-damping bracket 121 is arranged at the mounting position 111 and connected to the tailgate inner panel 110. The vibration-damping bracket 121 is formed with a mounting opening 1211, and the mounting opening 1211 can avoid the vibration-damping block 122. The vibration-damping block 122 can be arranged in the mounting opening 1211 to save the space required for arranging the vibration-damping assembly 120 in the X direction.

[0035] Furthermore, when the vehicle is traveling on a road with poor conditions, the tailgate 100 of the vehicle vibrates, and the tailgate inner panel 110 transmits the vibration to the vibration-damping block 122 through the vibration-damping bracket 121 and the vibration-damping connector 123. The vibration-damping block 122 is suspended in the mounting opening 1211 and can absorb the vibration, thereby helping to reduce the noise inside the vehicle.

[0036] In the related art, the shock absorber occupies a large space in the X direction. Before installing the shock absorber, it is necessary to reserve installation space between the vehicle's interior panel and the back door inner panel, resulting in the back door inner panel and the interior panel needing to be adjusted toward the cabin along the X direction, thereby encroaching on the X-direction space of the luggage compartment (also understood as the trunk).

[0037] The present application provides a vibration reduction assembly 120, and provides a mounting opening 1211 that penetrates along the X direction on the vibration reduction bracket 121, so that the vibration reduction block 122 is arranged in the mounting opening 1211, so as to save the space required for arranging the vibration reduction assembly 120, and there is no need to adjust the back door inner panel 110 and the interior trim panel toward the direction of the vehicle cabin, which is beneficial to prevent the space of the luggage compartment (which can also be understood as the trunk) from being occupied, and is beneficial to increasing the available space of the luggage compartment.

[0038] According to the tailgate 100 of the vehicle of the present invention, a vibration-damping assembly 120 is provided to absorb the vibration of the tailgate 100, thereby facilitating the reduction of the noise inside the vehicle, wherein a mounting opening 1211 is provided on the vibration-damping bracket 121 and is penetrated along the X direction, so that the vibration-damping block 122 can be disposed in the mounting opening 1211, which is facilitating the reduction of the size of the vibration-damping assembly 120 in the X direction, thereby facilitating the saving of the space required for arranging the vibration-damping assembly 120, and facilitating the increase of the available space of the luggage compartment.

[0039] Combination Figure 4 and Figure 5 In some embodiments of the utility model, the vibration-damping bracket 121 includes: a bracket body 1212, a mounting opening 1211 formed on the bracket body 1212; a mounting flange 1213, the mounting flange 1213 is connected to the bracket body 1212, and the mounting flange 1213 extends from the edge of the mounting opening 1211 along the X direction, and the vibration-damping connector 123 is connected between the mounting flange 1213 and the vibration-damping block 122.

[0040] Specifically, the mounting opening 1211 is arranged to penetrate the bracket body 1212 along the X-direction, the mounting flange 1213 is formed at the edge of the mounting opening 1211, and the mounting flange 1213 and the vibration damping block 122 are arranged at intervals to facilitate the arrangement of the vibration damping connecting piece 123, and the mounting flange 1213 and the vibration damping block 122 are arranged relative to each other, so that the vibration damping connecting piece 123 connects the vibration damping block 122 with the mounting flange 1213, thereby facilitating the connection of the vibration damping block 122 with the vibration damping bracket 121, which is beneficial to improving the assembly convenience of the vibration damping assembly 120.

[0041] Combination Figure 2 and Figure 3 In some embodiments of the present invention, the back door inner panel 110 is provided with a mounting boss 112 , the mounting boss 112 protrudes inward from the back door inner panel 110 , and the bracket body 1212 is mounted on the mounting boss 112 .

[0042] Specifically, the mounting bosses 112 protrude from the tailgate inner panel 110 along the X-direction toward the side close to the vehicle cabin. By providing the mounting bosses 112, it is helpful to improve the structural strength of the tailgate inner panel 110, and it is helpful to eliminate the additional reinforcement plate on the tailgate inner panel 110, thereby helping to reduce the weight of the tailgate 100, and can reduce the production cost of the tailgate 100, which is conducive to realizing the lightweight design of the vehicle and can reduce the production cost of the vehicle.

[0043] In the related art, in order to meet the durability requirements of the tailgate inner panel, a reinforcement plate is usually set on the tailgate inner panel at the position for installing the shock absorber before assembling the shock absorber. The reinforcement plate is usually connected to the tailgate inner panel through standard fastening parts. However, when the test vehicle completes the simulation experiment and determines that the tailgate does not need to be equipped with a shock absorber, the reinforcement plate and the standard fastening parts will be redundant, thereby increasing the weight and production cost of the tailgate.

[0044] The present application provides mounting bosses 112 on the tailgate inner panel 110, thereby improving the structural strength of the tailgate inner panel 110 and eliminating the additional reinforcement plate on the tailgate inner panel 110 and the standard fastening parts for connecting the reinforcement plate to the tailgate inner panel 110, thereby reducing the weight and production cost of the tailgate 100.

[0045] Furthermore, the bracket body 1212 is installed on the mounting boss 112 , which helps prevent the tail door inner panel 110 from being crushed when the bracket body 1212 is installed on the tail door inner panel 110 , and facilitates the positioning and installation of the bracket body 1212 and the tail door inner panel 110 , thereby improving the assembly convenience of the bracket body 1212 .

[0046] Combination Figure 1 and Figure 5In some embodiments of the present invention, the bracket body 1212 is further provided with a reinforcing flange 1214 , and the reinforcing flange 1214 extends from the outer periphery of the bracket body 1212 to a side away from the back door inner panel 110 .

[0047] Specifically, the reinforcing flange 1214 is arranged on the outer periphery of the bracket body 1212 , and the reinforcing flange 1214 is connected to the bracket body 1212 , wherein the connection position between the reinforcing flange 1214 and the bracket body 1212 is an arc-shaped transition, which is beneficial to improving the structural strength of the vibration-damping bracket 121 .

[0048] Furthermore, the reinforcing flange 1214 extends from the bracket body 1212 to the side away from the tailgate inner panel 110 so that the reinforcing flange 1214 can avoid the tailgate inner panel 110 to prevent the reinforcing flange 1214 and the tailgate inner panel 110 from interfering with each other during the installation process and affecting the assembly of the vibration reduction assembly 120.

[0049] Combination Figure 2 , Figure 3 and Figure 4 In some embodiments of the present invention, the back door inner panel 110 is provided with an avoidance groove 113 , the outer peripheral wall of the mounting flange 1213 is spaced apart from the groove wall of the avoidance groove 113 , and the vibration damping block 122 is disposed in the avoidance groove 113 .

[0050] It should be noted that the “outer peripheral wall of the mounting flange 1213 ” refers to the wall surface on one side of the mounting flange 1213 away from the vibration damping block 122 .

[0051] Specifically, the avoidance groove 113 can be formed on the mounting boss 112, and the avoidance groove 113 is recessed toward the side away from the vehicle cabin along the X-direction, and the mounting flange 1213 and the vibration-damping block 122 can extend into the avoidance groove 113 along the X-direction. The avoidance groove 113 is used to avoid the mounting flange 1213 and the vibration-damping block 122, which is beneficial to further save the space in the X-direction required for arranging the vibration-damping assembly 120, thereby helping to increase the available space in the luggage compartment.

[0052] Among them, the outer peripheral wall of the installation flange 1213 and the groove wall of the avoidance groove 113 are arranged at intervals, which is beneficial to prevent the installation flange 1213 from colliding with the avoidance groove 113 to generate noise, thereby helping to further reduce the noise inside the vehicle.

[0053] Optionally, an avoidance hole may be formed on the back door inner panel 110, and the avoidance hole is arranged to penetrate the back door inner panel 110 along the X direction. The function and setting position of the avoidance hole are the same as those of the above-mentioned avoidance groove 113. It can also be understood that the avoidance groove 113 can also be replaced by the avoidance hole. The avoidance hole can avoid the installation flange 1213 and the vibration damping block 122 and reduce the weight of the back door inner panel 110, which is conducive to realizing the lightweight design of the back door inner panel 110.

[0054] Combination Figures 2 to 4 In some embodiments of the present invention, the mounting boss 112 is provided with a plurality of mounting portions 114 , and the plurality of mounting portions 114 are arranged around the circumferential direction of the avoidance groove 113 ; the vibration-damping bracket 121 is provided with a plurality of connecting portions 1215 , and the plurality of connecting portions 1215 correspond one-to-one to the plurality of mounting portions 114 , respectively.

[0055] Specifically, the connecting portion 1215 can be arranged on the bracket body 1212, and multiple connecting portions 1215 can be arranged one-to-one with multiple mounting portions 114 in the X-direction of the vehicle, wherein the mounting portion 114 can be constructed as a hexagonal hole structure arranged along the X-direction of the vehicle and penetrating the back door inner panel 110, and a rivet nut 130 is arranged in the hexagonal hole structure, and the rivet nut 130 is riveted in the hexagonal hole, and the connecting portion 1215 can be constructed as a through hole arranged on the bracket body 1212, and the rivet nut 130 can cooperate with the threaded connector and be connected to the bracket body 1212 through the connecting portion 1215 and the mounting portion 114, thereby realizing the connection between the vibration-damping bracket 121 and the back door inner panel 110, and it is beneficial to improve the assembly convenience of the vibration-damping bracket 121 and the back door inner panel 110.

[0056] Furthermore, a plurality of connecting portions 1215 and mounting portions 114 are provided, which is beneficial to improving the connection strength between the vibration-damping bracket 121 and the tailgate inner panel 110 , thereby facilitating improving the connection reliability between the vibration-damping bracket 121 and the tailgate inner panel 110 .

[0057] Of course, it is understandable that the tailgate inner panel 110 and the vibration damping bracket 121 can also be assembled by other connection methods. For example, the tailgate inner panel 110 and the vibration damping bracket 121 can also be connected by bonding. The specific connection method can be determined according to actual production requirements and is not specifically limited here.

[0058] Combination Figure 1 and Figure 5 In some embodiments of the present invention, the bracket body 1212 is further provided with an annular reinforcing rib 1216 , and the annular reinforcing rib 1216 protrudes from the edge of the installation opening 1211 to a side away from the back door inner panel 110 .

[0059] Specifically, the annular reinforcement rib 1216 extends along the circumferential direction of the mounting opening 1211, that is, the annular reinforcement rib 1216 is arranged around the mounting opening 1211 in the axial direction of the mounting opening 1211, and the annular reinforcement rib 1216 bulges along the X-direction toward the side away from the tailgate inner panel 110, which is beneficial to further improve the structural strength of the bracket body 1212 and improve the service life of the shock-absorbing bracket 121.

[0060] In some embodiments of the present invention, the reinforcing flange 1214, the bracket body 1212, the annular reinforcing rib 1216 and the mounting flange 1213 are integrally formed.

[0061] Specifically, the vibration-damping bracket 121 can be constructed as a plate body with a hollow middle portion, and can be processed by press-fitting to form a reinforcing flange 1214, a bracket body 1212, an annular reinforcing rib 1216 and an installation flange 1213, which is beneficial to reducing the assembly difficulty and assembly process of the vibration-damping component 120 and improving the assembly convenience of the vibration-damping component 120.

[0062] Among them, the installation flange 1213 is arranged on the side of the annular reinforcement rib 1216 close to the vibration damping block 122, and the bracket body 1212 is arranged on the side of the annular reinforcement rib 1216 away from the vibration damping block 122, that is, the installation flange 1213 and the bracket body 1212 are spaced apart, which can prevent the installation flange 1213 and the bracket body 1212 from colliding with each other and is conducive to further improving the vibration absorption effect of the vibration damping assembly 120.

[0063] like Figure 5 As shown, in some embodiments of the utility model, the vibration-damping connecting member 123 includes: a first connecting seat 1231, the first connecting seat 1231 is connected to the mounting flange 1213; a second connecting seat 1232, the second connecting seat 1232 is connected to the vibration-damping block 122; and a connecting rod 1233, the connecting rod 1233 is connected between the first connecting seat 1231 and the second connecting seat 1232.

[0064] Specifically, the first connecting seat 1231 is fitted and connected to a side wall of the mounting flange 1213 close to the vibration damping block 122, which is beneficial to improving the connection reliability between the first connecting seat 1231 and the mounting flange 1213. The second connecting seat 1232 is spaced apart from the first connecting seat 1231, and the second connecting seat 1232 is fitted and connected to a side wall of the vibration damping block 122 close to the mounting flange 1213, which is beneficial to improving the connection reliability between the second connecting seat 1232 and the vibration damping block 122.

[0065] Furthermore, the two ends of the connecting rod 1233 are respectively connected to the first connecting seat 1231 and the second connecting seat 1232 , so that the vibration-damping block 122 can be installed and connected to the flange 1213 , thereby realizing the connection between the vibration-damping block 122 and the vibration-damping bracket 121 .

[0066] Optionally, multiple connecting rods 1233 can be provided, for example, the first connecting seat 1231 and the second connecting seat 1232 can be connected by two spaced-apart connecting rods 1233, which is beneficial to improving the connection reliability between the first connecting seat 1231 and the second connecting seat 1232, thereby improving the connection reliability between the vibration damping block 122 and the vibration damping bracket 121.

[0067] Of course, it is understandable that the number of connecting rods 1233 can be determined according to actual production requirements and is not specifically limited here, as long as the connection reliability between the first connecting seat 1231 and the second connecting seat 1232 is guaranteed.

[0068] Among them, at least two sides of the vibration damping block 122 can be connected by vibration damping connectors 123. For example, the vibration damping block 122 is provided with vibration damping connectors 123 on both sides in the Y direction, or the vibration damping block 122 is provided with vibration damping connectors 123 on both sides in the Y direction and on one side in the Z direction, so as to ensure the connection reliability between the vibration damping block 122 and the vibration damping bracket 121.

[0069] Of course, it is understandable that the specific number of vibration-damping connectors 123 can be determined according to actual production requirements and is not specifically limited here.

[0070] The vibration-damping connector 123 is constructed as a rubber component. After the rubber component is vulcanized, the vibration-damping block 122 can be connected to the mounting flange 1213 . The rubber component can also play a role in vibration reduction and energy absorption, which is beneficial to reducing the noise inside the vehicle.

[0071] In some embodiments of the present invention, the vibration-damping block 122 is constructed as a rectangular block, and two sides of the rectangular block in the length direction are connected to the mounting flanges 1213 through vibration-damping connectors 123 respectively.

[0072] It should be noted that the “length direction” is parallel to the Y direction of the vehicle, and the “thickness direction” is parallel to the X direction of the vehicle.

[0073] Specifically, the rectangular block has a small size in the X direction, which is beneficial to further reduce the space occupied by the vibration damping assembly 120 in the X direction. By arranging vibration damping connectors 123 on both sides of the rectangular block in the length direction, the connection reliability between the rectangular block and the mounting flange 1213 is improved, and the vibration damping effect can be improved, which is beneficial to further reduce the noise inside the vehicle.

[0074] Among them, the rectangular block can be formed by cutting flat steel bars. During the production and processing process, flat steel bars of corresponding thickness can be selected for cutting according to actual size requirements. No other processing steps are required, which is beneficial to improving the processing convenience of the vibration damping block 122, improving the production and processing efficiency of the vibration damping block 122, and reducing the processing cost of the vibration damping block 122.

[0075] The vehicle according to the embodiment of the present invention includes the tailgate 100 of the vehicle mentioned above.

[0076] Since the vehicle is provided with the above-mentioned tailgate 100 of the vehicle, a vibration-damping assembly 120 is provided to absorb the vibration of the tailgate 100, thereby facilitating the reduction of the noise inside the vehicle, wherein, by providing a mounting opening 1211 which is provided through the vibration-damping bracket 121 along the X direction, the vibration-damping block 122 can be provided in the mounting opening 1211, which is facilitating the reduction of the size of the vibration-damping assembly 120 in the X direction, thereby facilitating the saving of the space required for arranging the vibration-damping assembly 120, and facilitating the increase of the available space of the luggage compartment.

[0077] The back door 100 may be applied to a SUV vehicle (ie, a Sport Utility Vehicle or a Suburban Utility Vehicle).

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
