[0002] In the process of automobile design and manufacturing, in order to ensure the safety and durability of the vehicle, R&D personnel will set up baffles in some locations that are prone to collision and damage to protect important parts inside the car. The main function of these baffles is to isolate and buffer the direct contact between the car and obstacles, thereby preventing important parts from being damaged.

[0003] However, since these fenders are often in direct contact with the external environment, they are easily subject to wear, impact or damage. Therefore, in order to maintain the performance and appearance of the car, these fenders need to be frequently removed and replaced. However, in existing automobile design and manufacturing technologies, the installation and removal process of fenders is often not simple.

[0004] Specifically, some fenders require special tools or skills to be removed due to limitations in design or installation, which increases the difficulty and complexity of removal. At the same time, some fenders are closely connected to other parts of the car, and removal may cause unnecessary damage or impact to other parts. These factors make it difficult to quickly and conveniently remove and replace the fenders in actual use.

[0005] Therefore, how to improve the design and installation method of the baffle to make it easier to disassemble and replace has become an urgent problem to be solved. Utility Model Content

[0045] The embodiment of the present application provides a snap-in connection structure 1010 and a vehicle. The snap-in connection structure 1010 is used for vehicle protection.

[0046] like Figures 1 to 4 As shown, in a first aspect, an embodiment of the present application provides a snap connection structure 1010 , including a snap body 1100 , a first anti-detachment protrusion 1140 and a second anti-detachment protrusion 1150 .

[0047] like Figure 1 As shown, the snap body 1100 is arranged on the fender 1200 of the vehicle, and the snap body 1100 has a first end 1110, a second end 1120 and a third end 1130, one end of the second end 1120 is connected to the first end 1110, and the other end of the second end 1120 is connected to the third end 1130, and the first end 1110, the second end 1120 and the third end 1130 form a U-shaped block structure of the snap body 1100.

[0048] like Figure 1 As shown, the first anti-drop protrusion 1140 is disposed on a side of the first end 1110 away from the third end 1130. Figure 2As shown, the second anti-dropout protrusion 1150 is disposed on a side of the third end portion 1130 away from the first end portion 1110. The first anti-dropout protrusion 1140 and the second anti-dropout protrusion 1150 can prevent the buckle body 1100 from dropping out from the installation position.

[0049] like Figure 1 As shown, the thickness of the second end 1120 is H; when installing the snap-fit ​​connection structure 1010, the first end 1110 and the third end 1130 will be squeezed and deformed, so a certain insertion force needs to be applied when installing the snap-fit ​​connection structure 1010. The larger the thickness H of the second end 1120, the greater the insertion force that needs to be applied, the greater the installation difficulty but the less likely it is to fall off; the smaller the thickness H of the second end 1120, the smaller the insertion force that needs to be applied, the less difficult the installation but the easier it is to fall off. By setting the thickness H of the second end 1120, the size of the insertion force that needs to be applied during installation can be adjusted.

[0050] Exemplarily, 0.5 mm ≤ H ≤ 1.2 mm. Exemplarily, in one embodiment, H = 0.5 mm. In another embodiment, H = 0.856 mm. In another embodiment, H = 1.2 mm.

[0051] Exemplarily, in yet another embodiment, 2 mm ≤ H ≤ 5 mm. Exemplarily, in one embodiment, H = 2 mm. In another embodiment, H = 3 mm. In yet another embodiment, H = 5 mm.

[0052] like Figure 2 As shown, in one embodiment, a first inclined surface 1121 is provided on the second end portion 1120, and the first inclined surface 1121 is inclined at a first preset angle α along the end surface of the first end portion 1110 in a direction away from the first end portion 1110; the first inclined surface 1121 is provided to facilitate the installation of the snap-fit ​​connection structure 1010 and prevent jamming.

[0053] Exemplarily, 15°≤first preset angle α≤45°; Exemplarily, in one embodiment, the first preset angle α=15°; In another embodiment, the first preset angle α=30°. In another embodiment, the first preset angle α=45°.

[0054] like Figure 3 As shown, in one embodiment, the first end 1110 and the third end 1130 are inclined at a second preset angle β relative to the baffle 1200. Setting the second preset angle can provide support for the baffle 1200 through the buckle body 1100 to prevent the baffle 1200 from shaking.

[0055] Exemplarily, 95°≤second preset angle β≤135°; Exemplarily, in one embodiment, the second preset angle β=90°; In another embodiment, the second preset angle β=100°. In another embodiment, the second preset angle β=135°.

[0056] like Figure 4 As shown, in one embodiment, the inner wall of the second end portion 1120 includes a first inner wall 1122, a second inner wall 1124 and a third inner wall 1126, the second inner wall 1124 is located between the first inner wall 1122 and the third inner wall 1126, the second inner wall 1124 is an arc-shaped wall surface, and the angle between the first inner wall 1122 and the third inner wall 1126 is a third preset angle γ. The size of the third preset angle γ is negatively correlated with the arc length of the second inner wall 1124. The larger the third preset angle γ, the smaller the arc length of the cross section of the second inner wall 1124, the smaller the area of ​​the second inner wall 1124, and the smaller the insertion force when the snap-fit ​​connection structure 1010 is installed. The smaller the third preset angle γ, the larger the arc length of the cross section of the second inner wall 1124, the larger the area of ​​the second inner wall 1124, and the greater the insertion force when the snap-fit ​​connection structure 1010 is installed.

[0057] Exemplarily, 25°≤the third preset angle γ≤75°; Exemplarily, in one embodiment, the third preset angle γ=25°; In another embodiment, the third preset angle γ=45°. In another embodiment, the third preset angle γ=75°.

[0058] like Figure 2 As shown, in one embodiment, the first anti-slip protrusion 1140 has a first mating side wall 1141 and a second mating side wall 1142, and the first mating side wall 1141 is connected to the second mating side wall 1142. At the same time, the first mating side wall 1141 is connected to the outer wall of the second end 1120, and the inclination angle of the first mating side wall 1141 relative to the inner wall of the first end 1110 is smaller than the inclination angle of the second mating side wall 1142 relative to the inner wall of the first end 1110, so that the first mating side wall 1141 has a guiding function to realize the movement of the buckle body 1100 in a predetermined direction, and can also make the second mating side wall 1142 have a blocking effect, further enhancing the anti-slip effect of the first anti-slip protrusion 1140.

[0059] like Figure 3As shown, in one embodiment, the second anti-slip protrusion 1150 has a first clamping side wall 1151 and a second clamping side wall 1152, the first clamping side wall 1151 is connected to the outer wall of the second end 1120, and the first clamping side wall 1151 is connected to the second clamping side wall 1152, and the inclination angle of the first clamping side wall 1151 relative to the inner wall of the third end 1130 is smaller than the inclination angle of the second clamping side wall 1152 relative to the inner wall of the third end 1130, so that the first clamping side wall 1151 has a guiding function to realize the movement of the buckle body 1100 in a predetermined direction, and also enables the first clamping side wall 1151 to have a blocking effect, further enhancing the anti-slip effect of the second anti-slip protrusion 1150.

[0060] like Figure 1 and Figure 2 As shown, in one embodiment, a first rib 1111 is provided on a side surface of the first end portion 1110 away from the third end portion 1130 .

[0061] like Figure 3 As shown, in one embodiment, a second rib 1134 is disposed on a side surface of the third end portion 1130 away from the first end portion 1110 .

[0062] The first rib plate 1111 and the second rib plate 1134 can improve the overall structural stability and strength. The first rib plate 1111 and the second rib plate 1134 not only make the first end 1110 and the third end 1130 more durable, but also provide a strong guarantee for their application in various complex environments.

[0063] like Figure 3 As shown, in one embodiment, an arc-shaped plate body 1160 is provided at the connection between the end face of the first end 1110 and the baffle 1200, and at the connection between the end face of the third end 1130 and the baffle 1200. By providing the arc-shaped plate body 1160, the connection strength between the first end 1110 and the third end 1130 and the baffle 1200 can be increased to prevent stress concentration.

[0064] Second, as Figures 5 to 7 As shown, the embodiment of the present application provides a vehicle 1000, including a baffle 1200, a mounting plate 1300 and a snap-on connection structure 1010 as in any of the above embodiments. For simplicity and clarity, Figure 7 In the figure, the arrow indicating vehicle 1000 only shows a partial structure of the vehicle.

[0065] like Figure 5 As shown, one or more snap-connecting structures 1010 are fixedly connected to the baffle 1200 , which not only ensures a stable connection between the baffle 1200 and the mounting plate 1300 , but also facilitates the installation and removal of the baffle 1200 .

[0066] like Figure 7 As shown, the mounting plate is mounted on the vehicle body. A matching hole is provided on the mounting plate 1300, and the snap-fit ​​connection structure 1010 is snap-fitted and mounted at the matching hole. The end surface at the matching hole on the mounting plate 1300 can stop the first anti-slip protrusion 1140 and the second anti-slip protrusion 1150 of the snap-fit ​​connection structure, thereby limiting the snap-fit ​​connection structure 1010 from slipping out of the matching hole, so that the baffle is mounted on the mounting plate through the snap-fit ​​connection structure 1010; the number of matching holes is matched with the number of snap-fit ​​connection structures 1010. By snap-fitting these snap-fit ​​connection structures 1010 in the matching holes, the baffle 1200 can be firmly fixed on the mounting plate 1300.

[0067] The baffle 1200 can isolate and buffer the direct collision contact between the mounting plate 1300 and the obstacle, thereby preventing the mounting plate 1300 from being damaged. The baffle 1200 can also be quickly removed from the mounting plate 1300 or quickly installed on the mounting plate 1300 through the provided snap-fit ​​connection structure 1010, and the snap-fit ​​connection structure 1010 is tilted relative to the baffle 1200, and the end surface of the snap-fit ​​connection structure 1010 can better abut against the inner wall of the matching hole on the mounting plate 1300, so that the baffle 1200 is better snap-fitted to the mounting plate 1300 through the snap-fit ​​connection mechanism, so that the snap-fit ​​connection structure 1010 provides support for the baffle 1200.

[0068] The baffle 1200 not only has a protective function but also a decorative function. The baffle 1200 of different materials, colors and patterns can be selected according to actual needs to make the overall design more beautiful.

[0069] Exemplarily, two snap-fit ​​connection structures 1010 are provided on the baffle 1200. Figure 6 As shown, in another embodiment, four snap-fit ​​connection structures 1010 are disposed on the baffle 1200 .

[0070] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0071] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0072] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
