Connection structure and vehicle

Abstract

This application relates to a connection structure and a vehicle, specifically to the technical field of vehicle front-end design. The connection structure includes a mounting bracket, a connector, and fasteners. The mounting bracket has a crumple channel, a crumple portion, and a first connecting hole, arranged along a first direction. The crumple portion separates the crumple channel from the first connecting hole. The connector has a second connecting hole corresponding to the first connecting hole. Fasteners are simultaneously located in both the first and second connecting holes to connect the connector to the mounting bracket. When the connector and the mounting bracket move closer to each other in the first direction, the fasteners pass through the crumple portion into the crumple channel and can move along the crumple channel. This utilizes the deformation of the crumple portion and the displacement of the fasteners to absorb and buffer impact energy, thereby improving the crumple capability between the front end and the vehicle frame, reducing pedestrian injury during a collision between the vehicle's front end and a pedestrian, and meeting the vehicle's pedestrian protection requirements.

Description

Technical Field

[0001] This application relates to the technical field of vehicle front end, and more particularly to a connection structure and a vehicle. Background Technology

[0002] With the development of the automotive industry, the number of vehicles on the road is increasing, and traffic accidents are inevitable in daily life. Among them, low-speed collisions with pedestrians are frequent. The central part of the integrated bumper or the grille area of ​​the split bumper (hereinafter referred to as the front face) is an important buffer component at the front of the vehicle. It can absorb the energy generated by the collision and reduce the impact force transmitted to pedestrians, thereby reducing the injury to pedestrians.

[0003] In some vehicles, the crumple zone between the front end and the chassis is weak, making it difficult for the front end to crumple rearward. When a vehicle collides with a pedestrian, the impact energy cannot be effectively attenuated through the crumple zone of the front end and connecting parts, allowing the impact force to be transmitted to the pedestrian's body at a high intensity, resulting in significant injury. Current technology fails to adequately meet the requirements for pedestrian protection in vehicles. Utility Model Content

[0004] This application addresses, to at least some extent, one of the technical problems in the related art.

[0005] Therefore, this application aims to provide a connection structure and vehicle that, by setting a crumple zone and a crumple channel, uses the deformation of the crumple zone and the displacement of the fasteners to absorb and buffer impact energy, thereby improving the crumple capability between the front end and the frame, thereby reducing the injury to pedestrians when the front end of the vehicle collides with a pedestrian, and meeting the requirements of vehicle for pedestrian protection.

[0006] To achieve the above objectives, in a first aspect, this application provides a connection structure, comprising: The mounting bracket is provided with a collapsible channel, a collapsible portion and a first connecting hole, which are arranged along a first direction; the collapsible portion is used to separate the collapsible channel and the first connecting hole. The connector is provided with a second connecting hole, which is correspondingly provided with the first connecting hole; Fasteners are provided in both the first connecting hole and the second connecting hole to allow the connector to be connected to the mounting bracket. When the connector and the mounting bracket move closer to each other in the first direction, the fastener passes through the collapsible part and enters the collapsible channel, and can move along the collapsible channel.

[0007] In the technical solution, a first connecting hole is provided on the mounting bracket and a second connecting hole is provided on the connector. When the first connecting hole and the second connecting hole are aligned, the fastener is simultaneously provided in both the first connecting hole and the second connecting hole, so that the mounting bracket and the connector are connected to each other. By providing a crumple channel on the mounting bracket and separating the crumple channel from the first connecting hole through the crumple portion, when the mounting bracket and the connector collide and move closer to each other in the first direction, the fastener can pass through the crumple portion and enter the crumple channel and continue to move along the crumple channel. The deformation of the crumple portion and the displacement of the fastener are used to absorb the impact energy, thereby reducing the impact force transmitted to other components and reducing the direct impact intensity.

[0008] In some embodiments of this application, the collapsible portion is defined by a communication port, and the first connecting hole and the collapsible channel are interconnected through the communication port; the fastener passes through the communication port and enters the collapsible channel.

[0009] And / or, the first connecting hole communicates with the collapse channel, and the collapse portion is provided at the communication point between the first connecting hole and the collapse channel; the collapse portion protrudes from the inner edge of the communication point between the first connecting hole and the collapse channel.

[0010] In this technical solution, by defining a connection point within the crumpled portion, the strength of the crumpled portion is reduced, thereby minimizing its obstruction to the fastener's movement. This allows the fastener to smoothly break through the crumpled portion and enter the crumpled channel, thus dissipating impact energy. By providing a crumpled portion at the connection point between the first connecting hole and the crumpled channel, the crumpled portion can limit the fastener's movement, preventing it from breaking through the crumpled portion and entering the crumpled channel in the event of a minor collision or no collision, ensuring the reliability of the connection between the mounting bracket and the connector. Furthermore, it prevents the crumpled portion from becoming too strong, thus avoiding an increase in the force required to break it and ensuring its energy absorption effect.

[0011] In some embodiments of this application, in the second direction, the size of the crumpled portion is smaller than the size of the crumpled channel; the second direction is perpendicular to the first direction on the same plane. The fastener is provided with an insertion part, which is located in the first connecting hole and the second connecting hole; The dimension of the collapsible portion in the second direction is smaller than the outer diameter of the insertion portion, and the outer diameter of the insertion portion is less than or equal to the dimension of the collapsible channel in the second direction.

[0012] In the technical solution, by making the size of the collapsible part in the second direction smaller than the outer diameter of the insertion part, the collapsible part can limit the fastener without collision, preventing the fastener from entering the collapsible channel and ensuring the firmness and reliability of the connection between the mounting bracket and the connector; by making the outer diameter of the insertion part smaller than or equal to the size of the collapsible channel in the second direction, after the fastener passes through the collapsible part and enters the collapsible channel, the fastener can continue to move along the collapsible channel under the action of the collision force, thereby converting part of the impact energy into the kinetic energy of the fastener, and thus consuming the impact energy.

[0013] In some embodiments of this application, the mounting bracket is provided with reinforcing ribs that extend along a first direction and are located on at least one side of the collapse channel.

[0014] In the technical solution, reinforcing ribs are provided on the crumple channel to increase the strength of the mounting bracket and avoid reducing the strength of the mounting bracket due to the opening of the crumple channel, thus ensuring the reliability of the connection between the mounting bracket and the connector. By placing the reinforcing ribs at least on one side of the crumple channel in the second direction, the stiffness and bending and torsional resistance of the mounting bracket in the non-crunch direction (second direction) are increased, ensuring that when a collision occurs, the impact energy is preferentially used to drive the fastener to crumple along the first direction, rather than causing the mounting bracket itself to bend or twist.

[0015] Secondly, this application provides a vehicle, comprising: Frame; Front end; The connection structure is as described above; the mounting bracket is connected to the front end, and the connector is connected to the vehicle frame.

[0016] In the technical solution, the front end is connected to the vehicle frame through the cooperation of mounting brackets and connectors. When the vehicle collides with a pedestrian, the impact force on the front end is transmitted to the mounting brackets, causing relative movement between the mounting brackets and connectors. Fasteners pass through the crumple zone and enter the crumple channel, and can continue to move along the crumple channel. Through the deformation of the crumple zone and the movement of the fasteners in the crumple channel, the impact energy is effectively attenuated, reducing the force transmitted to the vehicle frame. This not only reduces the risk of damage to the vehicle frame and lowers maintenance costs, but also reduces the impact force on pedestrians, avoiding significant injury to pedestrians.

[0017] In some embodiments of this application, a base is provided on the side of the front of the vehicle facing the frame, and the base is used to fix the mounting bracket. One end of the mounting bracket, positioned along the first direction, is connected to the base, and the other end is connected to the connector.

[0018] In the technical solution, a base is set on the front face, and the mounting bracket is fixed on the base to achieve the assembly of the mounting bracket with the front face, thereby integrating the crumple structure into the front face. When the front face is involved in a collision, the crumple part can crumple, and the fasteners can move within the crumple channel to absorb the impact energy and reduce the injury to pedestrians.

[0019] In some embodiments of this application, the base is provided with a through groove that extends along the left and right direction of the vehicle and the opening of the through groove faces the vehicle frame; the mounting bracket is provided with a connecting part at one end connected to the base, and the connecting part is located in the through groove.

[0020] In the technical solution, a through groove is provided in the base and a connecting part is provided in the mounting bracket. The mutual cooperation between the connecting part and the through groove is used to realize the mutual connection between the mounting bracket and the base. By extending the through groove along the left and right direction of the vehicle, the mounting bracket has a certain installation adjustment margin in the left and right direction of the vehicle, which compensates for the manufacturing tolerances and assembly errors that may exist between the front face and the frame in the left and right direction of the vehicle.

[0021] In some embodiments of this application, the through groove tapers along its extension direction, and the shape of the connecting portion is adapted to the shape of the through groove.

[0022] In the technical solution, the through groove and the connecting part are designed to be tapered and adapted to each other so that the mounting bracket can only be inserted into the base in one direction, which increases the assembly efficiency and accuracy of the mounting bracket and the base; the tapered through groove can prevent the connecting part from moving towards the smaller end of the through groove, ensuring the firmness of the connection between the mounting bracket and the base, and preventing the connecting part from detaching from the through groove under the action of collision force.

[0023] In some embodiments of this application, one end of the connecting part along the extension direction of the through groove is provided with a limiting rib, and the other end is provided with a hook; the limiting rib abuts against one of the ports of the through groove, and the hook passes through the through groove and engages with the other port of the through groove.

[0024] In the technical solution, the connecting part is firmly set in the through groove by the synergistic effect of the limiting rib and the hook, which increases the firmness and reliability of the connection between the mounting bracket and the base, prevents the connecting part from coming out of the through groove during normal vehicle operation, and ensures the reliability and stability of the connection between the mounting bracket and the front face.

[0025] In some embodiments of this application, a snap-fit ​​block is provided in the through groove. The snap-fit ​​block is located at the port where the through groove and the snap hook cooperate. The snap-fit ​​block has a guide surface on the side facing the through groove. The guide surface is inclined in the direction close to the port and away from the through groove so as to guide the snap hook to snap with the side of the snap-fit ​​block away from the through groove.

[0026] In the technical solution, a guide surface is provided on the snap-fit ​​block to guide the snap hook to move in the through groove. When the snap hook moves along the guide surface, the guide surface squeezes the snap hook, causing the snap hook to move away from the front end, so that the snap hook passes over the snap-fit ​​block and snaps into the side of the snap-fit ​​block away from the through groove. This avoids the snap-fit ​​block interfering with the snap hook, reduces the assembly difficulty, and reduces the risk of damage to the parts during forced assembly.

[0027] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0034] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0035] Front panel 4 is a component installed at the front of the vehicle. It integrates a front bumper. When the front of the vehicle is involved in a collision, the front bumper deforms to absorb and buffer some of the impact energy, thereby protecting the frame and reducing the vehicle's maintenance costs.

[0036] In existing technologies, the crumple zone between the front fascia (4) and the vehicle frame is relatively weak. Especially with increasing demands for vehicle aesthetics, more and more front fascias (4) are equipped with lights to create illuminated front fascias (4), using perforated or translucent materials for illumination. For illuminated front fascias (4), the lights need to be positioned close to the front fascia (4) to achieve high brightness. During low-speed collisions, the small spacing between the lights makes it difficult for the front fascia (4) to crumple rearwards. When a vehicle collides with a pedestrian, the impact energy is difficult to effectively attenuate through the crumple zone (4) and its connecting parts, allowing the impact force to be directly transmitted to the pedestrian's body at a high intensity, resulting in significant injury. This not only makes it difficult for the vehicle to adequately meet pedestrian protection requirements, affecting pedestrian protection ratings, but also causes substantial harm to pedestrians.

[0037] Based on this, this application proposes a connection structure and a vehicle. By setting a crumple zone 111 and a crumple channel 101 in the connection structure, the deformation of the crumple zone 111 and the displacement of the fastener 3 are used to absorb and buffer impact energy, thereby improving the crumple capability between the front face 4 and the frame, reducing the injury to pedestrians when the front of the vehicle collides with a pedestrian, and meeting the requirements of the vehicle for pedestrian protection.

[0038] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0039] As attached Figures 1 to 2As shown in the schematic embodiment of the connection structure and vehicle of this application, the connection structure includes a mounting bracket 1, a connector 2, and a fastener 3; the mounting bracket 1 is provided with a collapsible channel 101, a collapsible portion 111, and a first connecting hole 102, the collapsible channel 101, the collapsible portion 111, and the first connecting hole 102 are arranged along a first direction; the collapsible portion 111 is used to separate the collapsible channel 101 from the first connecting hole 102; the connector 2 is provided with a second connecting hole, the second connecting hole being correspondingly provided with the first connecting hole 102; when the first connecting hole 102 and the second connecting hole are aligned, the fastener 3 is simultaneously provided in the first connecting hole 102 and the second connecting hole, so that the connector 2 and the mounting bracket 1 are connected to each other.

[0040] When the connector 2 and the mounting bracket 1 move closer to each other in the first direction, the fastener 3 passes through the collapsible portion 111 and enters the collapsible channel 101 and can move along the collapsible channel 101. The displacement of the fastener 3 and the deformation of the collapsible portion 111 are used to absorb the impact energy, thereby reducing the impact force transmitted from the connector 2 or the mounting bracket 1 to other components, reducing the intensity of the impact force on other components, and thus reducing collision damage.

[0041] It should be noted that when the connector 2 and the mounting bracket 1 do not move closer to each other in the first direction, or when the movement of the connector 2 and the mounting bracket 1 towards each other in the first direction is weak, the collapsible part 111 has a limiting effect on the fastener 3. The collapsible part 111 can prevent the fastener 3 from entering the collapsible channel 101, thereby ensuring the reliability and firmness of the connection between the mounting bracket 1 and the connector 2.

[0042] like Figure 1 and Figure 2 As shown, the mounting bracket 1 includes a body portion 11 and a connecting portion 12. The connecting portion 12 is located at one end of the body portion 11 along a first direction. The connecting portion 12 is used to connect with other components. The body portion 11 is used to connect with the connector 2 via a fastener 3. The collapsible channel 101, the collapsible portion 111, and the first connecting hole 102 are provided on the body portion 11.

[0043] In some embodiments, the fastener 3 is a component such as a bolt or screw, and the middle part of the fastener 3 is provided with an insertion part 31, which is disposed in the first connecting hole 102 and the second connecting hole.

[0044] It should be noted that if the strength of the crumple zone 111 is too small, the fastener 3 can easily pass through the crumple zone 111 and be placed in the crumple channel 101, resulting in poor energy absorption of the crumple zone 111. However, if the strength of the crumple zone 111 is too large, it will be more difficult for the fastener 3 to pass through the crumple zone 111, the crumple zone 111 will not easily deform, and the crumple zone 111 will not be able to effectively absorb energy.

[0045] In some embodiments of this application, the collapsible portion 111 is defined with a communication port 103. The first connecting hole 102 and the collapsible channel 101 are interconnected through the communication port 103. The fastener 3 passes through the communication port 103 and enters the collapsible channel 101 to reduce the strength of the collapsible portion 111 and reduce the obstruction of the collapsible portion 111 to the fastener 3, thereby facilitating the fastener 3 to break the collapsible portion 111 and enter the collapsible channel 101.

[0046] In some other embodiments of this application, the crumple portion 111 is a rib disposed between the first connecting hole 102 and the crumple channel 101. The crumple portion 111 is used to isolate the first connecting hole 102 and the crumple channel 101, so that the first connecting hole 102 and the crumple channel 101 cannot communicate, thereby increasing the strength of the crumple portion 111 and thus increasing the energy absorption effect of the crumple portion 111.

[0047] The first connecting hole 102 can be connected to the collapse channel 101 or isolated from it. It should be noted that if the first connecting hole 102 is connected to the collapse channel 101, the fastener 3 cannot pass through the collapse portion 111 and enter the collapse channel 101 without deforming the collapse portion 111.

[0048] like Figure 2 As shown, when the first connecting hole 102 is connected to the collapsible channel 101, the collapsible part 111 is provided at the connection between the first connecting hole 102 and the collapsible channel 101. The collapsible part 111 protrudes from the inner edge of the connection between the first connecting hole 102 and the collapsible channel 101. On the one hand, the collapsible part 111 can be used to limit the fastener 3, preventing the fastener 3 from being damaged when the mounting bracket 1 and the connector 2 have a small collision or no collision. The collapsible part 111 enters the collapsible channel 101, ensuring the firmness of the connection between the mounting bracket 1 and the connector 2. On the other hand, it can prevent the strength of the collapsible part 111 from being too large, which would increase the force required to damage the collapsible part 111, ensuring the energy absorption effect of the collapsible part 111.

[0049] The second direction is perpendicular to the first direction on the same plane; in the second direction, the size of the collapsible part 111 is smaller than the size of the collapsible channel 101, so that the collapsible part 111 can limit the fastener 3 without collision, prevent the fastener 3 from entering the collapsible channel 101, and ensure the firmness and reliability of the connection between the mounting bracket 1 and the connector 2.

[0050] It should be noted that the dimension of the collapse channel 101 in the second direction is also the width of the collapse channel 101.

[0051] The size of the collapsible portion 111 in the second direction is smaller than the outer diameter of the insertion portion 31, and the outer diameter of the insertion portion 31 is smaller than or equal to the size of the collapsible channel 101 in the second direction, so that after the fastener 3 passes through the collapsible portion 111 and enters the collapsible channel 101, the fastener 3 can move along the collapsible channel 101 under the action of the impact force, thereby converting part of the impact energy into the kinetic energy of the fastener 3, and thus consuming the impact energy.

[0052] In some embodiments, such as Figure 11 As shown, a washer 32 is fitted onto the fastener 3. The washer 32 is located on the side of the body 11 away from the connector 2. The washer 32 is used to increase the contact area between the fastener 3 and the body 11. The outer diameter of the washer 32 is larger than the inner diameter of the first connecting hole 102 to prevent the washer 32 from passing through the first connecting hole 102. The outer diameter of the washer 32 is also larger than the width of the collapsible channel 101 to prevent the fastener 3 from disengaging from the collapsible channel 101 in the vertical direction when it enters the collapsible channel 101.

[0053] like Figure 2 As shown, the mounting bracket 1 is provided with a reinforcing rib 112, which is located on the main body 11. The reinforcing rib 112 is used to increase the strength of the mounting bracket 1 and prevent the main body 11 from reducing its own strength due to the opening of the collapse channel 101, which would lead to unreliable connection between the mounting bracket 1 and the connector 2.

[0054] The reinforcing rib 112 extends along the first direction and is located at least on one side of the collapse channel 101 in the second direction to increase the stiffness and bending and torsional resistance of the mounting bracket 1 in the non-collapse direction (second direction), ensuring that when a collision occurs, the impact energy is preferentially used to drive the fastener 3 to collapse along the first direction, rather than causing the body part 11 to bend or twist.

[0055] Preferred, such as Figure 2 As shown, there are two reinforcing ribs 112, which are respectively located on both sides of the main body 11. The two reinforcing ribs 112 are located on both sides of the collapse channel 101 along the second direction.

[0056] Based on the above connection structure, this application provides a vehicle, which includes a frame, a front face 4 and the above connection structure; a mounting bracket 1 is connected to the front face 4, and a connector 2 is connected to the frame, so that the front face 4 is mounted on the frame.

[0057] like Figure 3 and Figure 4 As shown, the rear side of the front face 4 is positioned facing the vehicle frame, and the mounting bracket 1 is connected to the rear side of the front face 4 and located at the upper end of the front face 4.

[0058] It should be noted that the front face 4 is positioned along the front-rear direction of the vehicle, the left-right direction of the front face 4 is positioned along the left-right direction of the vehicle, and the upper and lower sides of the front face 4 are positioned along the height direction of the vehicle.

[0059] It should also be noted that the rear side of front face 4 can also be considered as the back of front face 4.

[0060] In addition, it should be noted that the connector 2 can be part of the frame or can be connected separately to the frame. The connection method between the connector 2 and the frame is a conventional technology in this field and will not be described in detail.

[0061] In addition, in this embodiment, the left and right directions of the vehicle are distinguished based on the direction a person faces when inside the vehicle.

[0062] In some embodiments, the first direction is arranged along the longitudinal direction of the vehicle, and the second direction is arranged along the lateral direction of the vehicle. When the front face 4 collides, the mounting bracket 1 and the connector 2 move closer to each other in the first direction.

[0063] When a vehicle collides with a pedestrian, the impact force on the front fascia 4 is transmitted to the mounting bracket 1, causing relative movement between the mounting bracket 1 and the connector 2. The fastener 3 passes through the crumple zone 111 and enters the crumple channel 101, and can continue to move along the crumple channel 101. Through the deformation of the crumple zone 111 and the movement of the fastener 3 within the crumple channel 101, the impact energy is effectively attenuated, reducing the force transmitted to the frame. This not only reduces the risk of frame damage and maintenance costs, but also reduces the impact force on pedestrians, avoiding significant injury to pedestrians.

[0064] like Figure 5 As shown, a base 41 is provided on the side of the front face 4 facing the vehicle frame. The base 41 is used to fix the mounting bracket 1. One end of the mounting bracket 1, which is arranged along the first direction, is connected to the base 41, and the other end is connected to the connector 2. By providing the base 41 on the front face 4 and connecting the base 41 to the mounting bracket 1, it is convenient to assemble the mounting bracket 1 onto the front face 4. A crumple structure is integrated on the front face 4, so that when the front face 4 is involved in a collision, the crumple portion 111 can crumple, and the fastener 3 can move within the crumple channel 101, thereby absorbing the impact energy and reducing injury to pedestrians.

[0065] In some embodiments, the base 41 is located at the upper end of the front face 4 and on the side of the front face 4 facing the vehicle frame.

[0066] like Figure 6 and Figure 7As shown, the base 41 is provided with a through groove 401, which extends along the left and right direction of the vehicle, and the opening of the through groove 401 is set towards the vehicle frame; the connecting part 12 is provided in the through groove 401, so that the mounting bracket 1 and the base 41 can be connected by the mutual cooperation between the connecting part 12 and the through groove 401.

[0067] It should be noted that the through groove 401 extends along the left and right direction of the vehicle, which allows the mounting bracket 1 to have a certain installation adjustment margin in the left and right direction of the vehicle, compensating for possible manufacturing tolerances and assembly errors between the front face 4 and the frame.

[0068] It should also be noted that the two side walls of the through groove 401 are set along the vehicle height direction, which is usually set in the vertical direction. The connecting part 12 is set in the through groove 401, and the lower side wall of the through groove 401 can support the connecting part 12, increasing the firmness and reliability of the connection between the mounting bracket 1 and the base 41.

[0069] In some embodiments, such as Figure 7 As shown, a limiting part 412 is provided on the base 41. The limiting part 412 is located at the groove opening and is provided on the side wall of the through groove 401. The limiting part 412 is provided along the extension direction of the through groove 401. When the connecting part 12 is provided in the through groove 401, the limiting part 412 and the side of the connecting part 12 away from the through groove 401 abut against each other to prevent the connecting part 12 from disengaging from the through groove 401 in the first direction, thereby increasing the firmness and reliability of the connection between the mounting bracket 1 and the base 41.

[0070] Preferably, the two sides of the slot are arranged opposite each other along the height direction of the vehicle, and the two sides of the slot are respectively provided with limiting parts 412. The two limiting parts 412 are respectively provided on the two side walls of the through slot 401 to increase the limiting effect on the connecting part 12.

[0071] like Figure 6 and Figure 7 As shown, the through groove 401 gradually narrows along its extension direction, and the shape of the connecting part 12 is adapted to the shape of the through groove 401 so that the connecting part 12 and the inner wall of the through groove 401 fit together, so as to avoid the connecting part 12 from shaking and making abnormal noise in the through groove 401, and to ensure the connection effect between the connecting part 12 and the base 41.

[0072] The through groove 401 is designed with a tapered structure. The two ends of the through groove 401 in the extension direction are a wide end and a narrow end. The connecting part 12 can only move from the wide end to the narrow end in the through groove 401, so that the mounting bracket 1 can only be inserted into the base 41 in one direction, thereby increasing the assembly efficiency and accuracy of the mounting bracket 1 and the base 41.

[0073] The tapered through groove 401 prevents the connecting part 12 from moving excessively towards the narrow end within the through groove 401 and disengaging from it, ensuring the firmness of the connection between the mounting bracket 1 and the base 41, and preventing the connecting part 12 from disengaging from the through groove 401 in the left-right direction of the vehicle under the action of impact force. In some embodiments, the through groove 401 is wedge-shaped in its extending direction.

[0074] like Figure 10 As shown, the connecting part 12 is provided with a limiting rib 121 at one end along the extension direction of the through groove 401, and a hook 122 at the other end; the limiting rib 121 abuts against one port of the through groove 401, and the hook 122 passes through the through groove 401 and engages with the other port of the through groove 401. Through the synergistic effect of the limiting rib 121 and the hook 122, the connecting part 12 is firmly set in the through groove 401, which increases the firmness and reliability of the connection between the mounting bracket 1 and the base 41, prevents the connecting part 12 from coming out of the through groove 401 during normal vehicle operation, and ensures the stability of the connection structure.

[0075] It should be noted that when the limiting rib 121 abuts against the wide end of the through groove 401, the hook 122 engages with the narrow end of the through groove 401 to achieve precise positioning of the mounting bracket 1 in the left and right directions of the vehicle.

[0076] like Figure 6 , Figure 7 and Figure 10 As shown, a snap-fit ​​block 411 is provided in the through groove 401. The snap-fit ​​block 411 is located at the narrow end of the through groove 401, and the snap hook 122 snaps into the snap-fit ​​block 411.

[0077] In some embodiments, when the hook 122 and the locking block 411 are engaged on the side away from the through groove 401, the limiting rib 121 abuts against the wide end of the through groove 401 to limit the connection part 12 in the second direction and prevent the connection part 12 from continuing to move in the second direction, thereby fixing the mounting bracket 1.

[0078] like Figure 6 , Figure 7 and Figure 10 As shown, the snap-fit ​​block 411 has a guide surface 4111 on the side facing the through groove 401. The guide surface 4111 is inclined in the direction away from the front face 4 along the direction close to the narrow end of the through groove 401, so as to guide the snap hook 122 to pass over the snap-fit ​​block 411 and snap with the side of the snap-fit ​​block 411 away from the through groove 401.

[0079] Since the distance between the guide surface 4111 and the bottom of the through groove 401 increases in the second direction away from the bottom of the groove, when the hook 122 moves along the guide surface 4111, the guide surface 4111 squeezes the hook 122, so that the hook 122 moves in the first direction away from the front face 4. This reduces the interference and obstruction of the hook 122 by the snap block 411 when it passes through the through groove 401, reduces the assembly difficulty, and reduces the risk of damage to the parts during forced assembly.

[0080] In some embodiments, such as Figure 2 As shown, the hook 122 is connected to the connecting part 12 via the intermediate section 123. The vertical dimension of the intermediate section 123 is smaller than that of the connecting part 12. The intermediate section 123 can be deformed so that the hook 122 can pass smoothly through the locking block 411 in the through groove 401, thus avoiding the locking block 411 from obstructing the movement of the hook 122.

[0081] It should be noted that when the hook 122 engages with the locking block 411, the middle section 123 deforms.

[0082] It should also be noted that the locking block 411 is located in front of the movement path of the hook 122 toward the wide end of the through groove 401. The locking block 411 obstructs the hook 122. Without external force, the hook 122 cannot pass the locking block 411 and move toward the wide end of the through groove 401.

[0083] In addition, it should be noted that the working principle of the hook 122 and the contact block 411 is a conventional technology in this field and will not be elaborated here.

[0084] It should be noted that the through groove 401 can gradually narrow from the left side of the vehicle to the right side, or from the right side of the vehicle to the left side. The different narrowing directions of the through groove 401 in the left-right direction of the vehicle correspond to the different positions of the limiting rib 121 and the hook 122 on the connecting part 12. However, it can be determined that the limiting rib 121 is set corresponding to the wide end of the through groove 401, the hook 122 is set corresponding to the narrow end of the through groove 401, and the snap block 411 is set at the narrow end of the through groove 401.

[0085] The installation method of mounting bracket 1 is as follows: the connecting part 12 is placed in the through groove 401 from the wide end of the through groove 401 and moves towards the narrow end of the through groove 401. The hook 122 is located at the front end of the moving direction of the connecting part 12. When the hook 122 passes the locking block 411, the hook 122 moves along the guide surface 4111 and the middle section 123 deforms, so that the hook 122 passes smoothly through the locking block 411. After the hook 122 passes through the locking block 411, the limiting rib 121 abuts against the wide end of the through groove 401 to prevent the connecting part 12 from continuing to move towards the narrow end. The hook 122 and the locking block 411 lock against each other to prevent the connecting part 12 from moving towards the wide end, thereby realizing the installation of mounting bracket 1 on base 41.

[0086] A mounting bracket 1 is provided on the front face 4, and a crumple section 111 and a crumple channel 101 are provided on the mounting bracket 1 to integrate a crumple structure including the crumple section 111 and the crumple channel 101 on the front face 4. When a pedestrian collides with the front face 4, the crumple structure crumples, which can prolong the collision time, smooth the impact force curve, reduce the peak acceleration and bending moment applied to the pedestrian, and reduce the injury to the pedestrian. Thus, the injury to the pedestrian can be minimized in the event of a pedestrian-vehicle collision.

[0087] It should be noted that the application of the connection structure is not limited to the connection between the front face 4 and the frame, but is also used for two other parts that are prone to mutual movement.

[0088] It should also be noted that a front fascia 4 is usually connected to the chassis through multiple connection structures to ensure the reliability of the connection between the front fascia 4 and the chassis. The number of connection structures can be adjusted according to the size of the vehicle and the actual connection needs.

[0089] Through the description of multiple embodiments of the connection structure and vehicle of this application, it can be seen that the connection structure and vehicle embodiments of this application have at least one or more of the following advantages: 1. By setting a crumple section 111 in the mounting bracket 1, the crumple section 111 separates the crumple channel 101 from the first connecting hole 102. When the front face 4 collides, the fastener 3 can pass through the first connecting hole 102 through the crumple section 111 and enter the crumple channel 101, so that the crumple section 111 can deform and collapse to absorb the impact energy. After the fastener 3 enters the crumple channel 101, it can continue to move along the crumple channel 101 to convert part of the impact energy into the kinetic energy of the fastener 3, further reducing the impact energy, thereby reducing the impact energy to reduce the injury to pedestrians, and also reducing the impact energy to reduce the damage to the front face 4, thus reducing the maintenance cost of the front face 4.

[0090] 2. By setting a base 41 on the side of the front face 4 facing the frame, and forming a through groove 401 extending in the left and right direction of the vehicle, the mounting bracket 1 is positioned in the through groove 401 in the left and right direction of the vehicle. The through groove 401 and the connecting part 12 are designed as a matching tapered structure. With the use of the hook 122 and the limiting rib 121, the relative movement of the mounting bracket 1 and the base 41 in the left and right direction of the vehicle is prevented, thereby increasing the firmness of the connection between the mounting bracket 1 and the base 41.

[0091] 3. The connection structure formed by mounting bracket 1 and connector 2 connected by fastener 3 can be applied to other interconnected parts that may collide. It has high versatility and wide applicability, and is not limited to the connection between the front face 4 and the frame.

[0092] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
