The number of cars on the road is increasing year by year, and more and more people own private cars. This widespread adoption of automobiles has spurred the development of automotive parts manufacturing and design.

[0034] The anti-collision beam assembly is an important component of automobiles. It consists of vehicle body panels and anti-collision beams. The anti-collision beams are installed on the vehicle body panels. In related technologies, the anti-collision beams are usually directly installed on the vehicle body panels by bolting. However, this method makes it difficult to effectively position the anti-collision beams and vehicle body panels before fixing them, which greatly increases the overall operation time and production costs.

[0035] To address the technical problems existing in related technologies, this application provides a vehicle, see [link to relevant documentation]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of an embodiment of the vehicle provided in this application. Figure 2 This is a schematic diagram of an embodiment of the anti-collision beam assembly provided in this application.

The battery device can be used to power vehicle 1; for example, it can serve as the operating power source for vehicle 1.

[0037] See Figures 2 to 5 , Figure 3 This is a schematic diagram of an embodiment of the vehicle enclosure 100 provided in this application. Figure 4 This is a schematic diagram of an embodiment of the anti-collision beam 200 provided in this application. Figure 5 yes Figure 2 The diagram shows the structure of the dashed box B in the anti-collision beam assembly 10.

[0038] The anti-collision beam assembly 10 includes a vehicle side panel 100 and an anti-collision beam 200. The vehicle side panel 100 has a main body 110 and a limiting structure 120. The main body 110 and the limiting structure 120 are connected. The limiting structure 120 has a snap-fit ​​groove 121. The opening of the snap-fit ​​groove 121 is located at the upper end of the bottom wall of the snap-fit ​​groove 121 in the gravity direction G. The anti-collision beam 200 has a mounting part 210 and a plug-in part 220. The mounting part 210 and the plug-in part 220 are connected. The plug-in part 220 is inserted into the snap-fit ​​groove 121 along the gravity direction G so that the vehicle side panel 100 and the main body 110 are fixed by the plug-in part 220 and the limiting structure 120.

[0039] The vehicle side panel 100 can be a rear side panel of the vehicle, located at the rear of the vehicle. The main body 110 of the vehicle side panel 100 has two opposing sides. When the main body 110 is installed on the vehicle body, the side surface of the main body 110 facing the vehicle body is used to connect with the vehicle's longitudinal beams or other structures, and the outer side surface of the main body 110 facing the vehicle body is used to connect with the anti-collision beam 200. Specifically, the limiting structure 120 can be located on the outer side surface of the main body 110 facing the vehicle body. The limiting structure 120 has a snap-fit ​​groove 121. The shape of the snap-fit ​​groove 121 can be set according to the actual situation. When the main body 110 is installed on the vehicle body, the opening of the snap-fit ​​groove 121 is set upward, so that the insertion part 220 of the anti-collision beam 200 can be inserted into the snap-fit ​​groove 121 from top to bottom. At the same time, the snap-fit ​​groove 121 can also limit the insertion part 220 in the direction of gravity G.

[0040] The shape and size of the mounting part 210 can be set according to the actual situation. For example, the mounting part 210 can match the partial shape of the main body part 110 where the limiting structure 120 is provided. The plug-in part 220 is fixedly connected to the mounting part 210. For example, the plug-in part 220 can be connected to the edge side wall of the mounting part 210, or the mounting part 210 has a through hole in the middle, and the plug-in part 220 is connected to the side wall of the through hole. In some feasible embodiments, if it is necessary to fix the anti-collision beam 200 and the vehicle side panel 100 together, the mounting part 210 and the main body part 110 can be fitted together first, and the insertion part 220 is located above the limiting structure 120 in the gravity direction G. Then, the mounting part 210 is guided by the main body part 110 so that the insertion part 220 moves in the gravity direction G and is inserted into the locking groove 121 from the opening of the locking groove 121, so that the vehicle side panel 100 and the main body part 110 are initially positioned by the insertion part 220 and the limiting structure 120. Then, the vehicle side panel 100 and the anti-collision beam 200 can be detachably connected by bolts or other fixing structures.

[0041] Through the above-described embodiments, the slot opening of the snap-fit ​​groove 121 is located at the upper end of the bottom wall of the snap-fit ​​groove 121 in the gravity direction G, which facilitates the insertion part 220 to be inserted into the snap-fit ​​groove 121 in the gravity direction G, so that the vehicle panel 100 and the main body 110 are fixed by the insertion part 220 and the limiting structure 120, thereby simplifying the installation method of the anti-collision beam 200 and the vehicle panel 100 and reducing the overall operation time, etc.

[0042] Furthermore, the anti-collision beam 200 includes an anti-collision main body 230 and a main body 110. The number of mounting parts 210 includes two, which are connected to both sides of the main body 230 and the main body 110. Each mounting part 210 is connected to at least one insertion part 220. The number of limiting structures 120 corresponds to the number of insertion parts 220, and one insertion part 220 is inserted into a snap-fit ​​groove 121. The main body 110 of the anti-collision main body 230 may protrude from the mounting parts 210. When the anti-collision beam 200 is installed on the vehicle side panel 100, the main body 110 of the anti-collision main body 230 may be spaced apart from the main body 110 of the vehicle side panel 100. The main body 110 of the anti-collision body 230 can extend along the width of the vehicle. There can be two mounting portions 210, which can be connected to both ends of the main body 110. Each mounting portion 210 can be provided with at least one insertion portion 220. Correspondingly, the number and position of the limiting structures 120 can correspond to the number and position of the insertion portions 220, thereby allowing one insertion portion 220 to be inserted into one snap-fit ​​groove 121.

[0043] In some embodiments, the main body 110 has a first clearance opening 111, which is located at the upper end of the limiting structure 120 in the gravity direction G. The mounting part 210 has a second clearance opening 211, and the insertion part 220 and the limiting structure 120 are located in the second clearance opening 211. Figure 3 As shown, the first clearance opening 111 can penetrate through the opposite two surfaces of the main body 110. The shape and size of the first clearance opening 111 can be set according to the actual situation. One first clearance opening 111 can correspond to one limiting structure 120. One first clearance opening 111 can be located at the upper end of the limiting structure 120 in the direction of gravity G, so that the insertion part 220 can be inserted into the locking groove 121 from the opening of the locking groove 121 through the first clearance opening 111. Figure 4 As shown, the second clearance opening 211 can penetrate the opposite sides of the mounting portion 210. The shape and size of the second clearance opening 211 can be set according to the actual situation. One second clearance opening 211 can correspond to one insertion portion 220. The insertion portion 220 can be located in the second clearance opening 211. The insertion portion 220 can be fixedly connected to the upper edge of the second clearance opening 211 so that the insertion portion 220 can avoid the limiting structure 120 through the second clearance opening 211 and be inserted into the snap-fit ​​groove 121 from the slot opening of the snap-fit ​​groove 121. Figure 5 As shown, when the plug part 220 is inserted into the snap-fit ​​groove 121, the plug part 220 is inserted into the snap-fit ​​groove 121, and the limiting structure 120 is located in the second clearance opening 211.

[0044] Furthermore, the distance between the side of the first clearance opening 111 away from the limiting structure 120 and the opening of the snap-fit ​​groove 121 is between 15mm and 30mm. Specifically, the distance between the side of the first clearance opening 111 away from the limiting structure 120 and the opening of the snap-fit ​​groove 121 can be, but is not limited to, 15mm, 17mm, 19mm, 20mm, 25mm, or 30mm, etc. The distance between the side of the first clearance opening 111 away from the limiting structure 120 and the opening of the snap-fit ​​groove 121 is between 15mm and 25mm, between 15mm and 23mm, between 20mm and 25mm, between 15mm and 20mm, or between 20mm and 30mm.

[0045] Combination Figure 6 and Figure 7 , Figure 6 yes Figure 2 The diagram shows a cross-sectional view of the anti-collision beam assembly 10 along the AA direction. Figure 7 yes Figure 6 An enlarged schematic diagram of the structure within the dashed box.

[0046] The limiting structure 120 includes a first limiting block 122, which protrudes from the main body 110 in the thickness direction X. The insertion part 220 abuts against the first limiting block 122 in the thickness direction X, wherein the thickness direction X is perpendicular to the gravity direction G. The first limiting block 122 may have a flat plate structure. The first limiting block 122 protrudes outward from the main body 110 in the thickness direction X, thereby making the size of the locking groove 121 sufficient to allow the insertion part 220 to be inserted into the locking groove 121. The thickness direction X can be the thickness direction X of the mounting part 210, or when the anti-collision beam assembly 10 is installed in a vehicle, the thickness direction X can also be understood as the length direction of the vehicle, and the gravity direction G can be understood as the height direction of the vehicle.

[0047] Furthermore, the limiting structure 120 includes a second limiting block 123, which surrounds a portion of the first limiting block 122. The first limiting block 122 is connected to the main body 110 via the second limiting block 123. The first limiting block 122 and the second limiting block 123 cooperate to form a snap-fit ​​groove 121. The second limiting block 123 limits the insertion portion 220 in the width direction Y, wherein the gravity direction G, the width direction Y, and the thickness direction X are mutually perpendicular. The shape and size of the second limiting block 123 can be set according to actual conditions. For example, the second limiting block 123 can be in the shape of a semi-circular ring. The second limiting block 123 can surround a portion of the first limiting block 122, thereby connecting the first limiting block 122 to the main body 110 via the second limiting block 123. The portion of the first limiting block 122 not surrounded by the second limiting block 123 can be used to form the opening of the snap-fit ​​groove 121. When the connector 220 is inserted into the connector slot, the connector 220 can be limited in the thickness direction X by the first limiting block 122, and the connector 220 can be limited in the width direction Y by the second limiting block 123. When the anti-collision beam assembly 10 is installed in a vehicle, the width direction Y can be understood as the width direction Y of the vehicle.

[0048] Furthermore, the first limiting block 122 includes a first arcuate portion 1221 and a first extension portion 1222. The first arcuate portion 1221 is connected to the main body portion 110, and the first extension portion 1222 is connected to the side of the first arcuate portion 1221 away from the main body portion 110. The first arcuate portion 1221 may protrude outward relative to the main body portion 110, and the radius of the circle corresponding to the first arcuate portion 1221 may be between 10mm and 15mm. Specifically, the radius of the circle corresponding to the first arcuate portion 1221 may include, but is not limited to, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm, etc. One end of the first arcuate portion 1221 is connected to the main body portion 110, and the other end is connected to the first extension portion 1222. The shape and size of the first extension portion 1222 can be set according to actual conditions, and the first extension portion 1222 can be used to limit the insertion portion 220 in the thickness direction X, etc.

[0049] And / or, the insertion portion 220 includes a second arcuate portion 221 and a second extension portion 222. The second arcuate portion 221 is connected to the mounting portion 210, and the second extension portion 222 is connected to the side of the second arcuate portion 221 away from the mounting portion 210. The second arcuate portion 221 may protrude inward relative to the mounting portion 210, and the radius of the circle corresponding to the second arcuate portion 221 may be between 3mm and 7mm. Specifically, the radius of the circle corresponding to the second arcuate portion 221 may include, but is not limited to, 3mm, 4mm, 5mm, 6mm, or 7mm, etc. One end of the second arcuate portion 221 is connected to the mounting portion 210, and the other end is connected to the second extension portion 222. The shape and size of the second extension portion 222 can be set according to actual conditions.

[0050] In some embodiments, the protrusion of the first limiting block 122 beyond the main body 110 in the thickness direction X is between 4 mm and 6 mm. Specifically, the protrusion of the first limiting block 122 beyond the main body 110 in the thickness direction X may include, but is not limited to, 4 mm, 4.5 mm, 5 mm, 5.5 mm, or 6 mm, etc. The protrusion of the first limiting block 122 beyond the main body 110 in the thickness direction X is between 4 mm and 5 mm, between 5 mm and 6 mm, between 5.5 mm and 6 mm, between 4.5 mm and 5.5 mm, or between 4 mm and 5.5 mm, etc.

[0052] In summary, the slot opening of the snap-fit ​​groove 121 is located at the upper end of the bottom wall of the snap-fit ​​groove 121 in the direction of gravity G, which facilitates the insertion part 220 to be inserted into the snap-fit ​​groove 121 in the direction of gravity G, so that the vehicle panel 100 and the main body 110 are fixed by the insertion part 220 and the limiting structure 120, thereby simplifying the installation method of the anti-collision beam 200 and the vehicle panel 100 and reducing the overall operation time.
