[0037] The present invention provides a pedestrian leg impact protection structure and a car. Figures 1 to 4 The present invention provides a pedestrian leg impact protection structure and an embodiment of a car.

[0038] Please also read Figures 1 to 3 The pedestrian leg impact protection structure includes a support plate 1, a plurality of support members 2 and a first elastic telescopic rod 3. The support plate 1 is used to be arranged on the rear side of a front bumper 4. The plurality of support members 2 are arranged on the rear side of the support plate 1 to fix the support plate 1 to a front end frame 5 of a car. One end of the first elastic telescopic rod 3 is hinged to the rear side of the support plate 1, and the other end is hinged to the left or right side of the support member 2.

[0039] The support plate 1 and the support member 2 are arranged between the front bumper 4 and the front end frame 5 in sequence. The support plate 1 is arranged on the rear side of the front bumper 4 to support the front bumper 4 and increase the strength of the front bumper 4, so that the front bumper 4 can share part of the impact energy with the help of the support plate 1 on the rear side after being hit, so as to reduce the impact strength during the impact, thereby reducing the damage caused by the front bumper 4 to the legs of pedestrians. The support member 2 is arranged between the support plate 1 and the front end frame 5 of the automobile, and is supported at different positions on the rear side of the support plate 1 by multiple support members 2, so as to enhance the bearing capacity of the support plate 1 when it is hit, avoid the support plate 1 from being easily broken in the impact due to the lack of support structure at the rear, and also reduce the possibility of the support plate 1 breaking after being hit, thereby avoiding the problem of the support plate 1 forming a sharp point at the fracture to stab the legs of pedestrians due to the fracture.

[0040] Part of the rear side of the support plate 1 is supported by the support member 2, thereby enhancing the impact resistance of part of the support plate 1. However, the impact resistance of the position without the support member 2 is weaker than that of the position with the support member 2, and is more likely to break and be damaged during a collision, thereby forming a burr to cause secondary damage to the legs of pedestrians. Therefore, a first elastic telescopic rod 3 is provided to support the position on the support plate 1 that is not supported by the support member 2, thereby enhancing the strength of the part of the support plate 1 that is not reinforced by the support member 2, making it difficult for the support plate 1 to break and be damaged during a collision. At the same time, the cooperation between the support plate 1 and the first elastic telescopic rod 3 enhances the ability of the support plate 1 to absorb impact force, so that the support plate 1 can weaken the impact force formed by the collision after the front bumper 4 is hit, thereby reducing the impact strength, thereby reducing the impact damage to the legs of pedestrians.

[0041] One end of the first elastic telescopic rod 3 is arranged at a position where there is no support member 2 on the rear side of the support plate 1, and the other end is connected to the side of the support member 2, so that the position of the support plate 1 without the support member 2 is supported by the first elastic telescopic rod 3 after being hit and bent backwards. At the same time, the first elastic telescopic rod 3 weakens the impact force on this part of the support plate 1 through elastic potential energy, and reduces the bending degree of this part of the support plate 1 after being hit, so that the support plate 1 is difficult to break or damage in the impact. Specifically, the other end of the first elastic telescopic rod 3 is closely connected to the side of the support member 2 to form a unique support structure. When the support plate 1 bends backwards after being hit, the first elastic telescopic rod 3 can support this part in time to prevent it from excessive bending or even breaking. In addition, the first elastic telescopic rod 3 also has a significant elastic potential energy characteristic. When the support plate 1 is hit, the first elastic telescopic rod 3 can weaken the impact force on this part of the support plate 1 through its own elastic potential energy. The buffering effect of this elastic potential energy can effectively reduce the bending degree of the support plate 1 after the impact, thereby greatly reducing the possibility of the support plate 1 being broken or damaged due to the impact. Through this ingenious design, the first elastic telescopic rod 3 not only improves the overall stability and safety of the support plate 1, but also extends its service life, ensuring the reliability and durability of the entire structure when facing accidental impacts.

[0042] Therefore, in the technical solution provided by the present invention, the support plate 1 is used to be arranged on the rear side of the front bumper 4, the multiple support members 2 are arranged on the rear side of the support plate 1, and are used to fix the support plate 1 to the front end frame 5 of the car, one end of the first elastic telescopic rod 3 is hinged to the rear side of the support plate 1, and the other end is hinged to the side of the support member 2. By adding the support plate 1, the strength of the front bumper 4 is enhanced, and the damage to the legs of pedestrians when impacted is reduced. At the same time, a buffer component is added to the rear side of the support plate 1 to enhance the ability of the support plate 1 to weaken the impact strength, thereby reducing the damage to the legs of pedestrians when the car hits the pedestrians. The support plate 1, the support member 2 and the buffer component cooperate with each other to enhance the ability of the front bumper 4 to weaken the impact strength, so that the impact damage to the legs of pedestrians caused by the front bumper 4 is reduced.

[0043] Furthermore, the support plate 1 is provided with at least one slot corresponding to the position between two adjacent support members 2 .

[0044] By providing a plurality of grooves on the support plate 1, the deformation area of ​​the support plate 1 can be increased through the grooves when the support plate 1 is impacted, so that the support plate 1 can undergo greater plastic deformation when impacted, thereby absorbing more impact energy and reducing the impact strength. At the same time, the stress generated at the grooves is concentrated. The impact strength can be reduced by evenly distributing the grooves. At the same time, the position of the fracture of the support plate 1 and the number of fractures can be effectively controlled by the setting of the grooves. The position of the grooves is the position where the support plate is most likely to fracture. By providing a plurality of grooves, the spikes of the support plate after fracture are difficult to extend to the outside to injure the legs of pedestrians after they break, thereby reducing the possibility of the sharp spikes formed by the fracture injuring the legs of pedestrians.

[0045] The strength of some positions of the support plate 1 is enhanced by the support member 2, and the possibility of the support plate 1 breaking during a collision is reduced. However, when a pedestrian's legs are at this position during a collision, the excessive strength of the support plate 1 will cause more serious damage. Therefore, it is necessary to make the support member 2 reduce the damage to the pedestrian's legs during a collision while enhancing the strength of the support plate 1. Specifically, in an embodiment of the present invention, the support member 2 includes a fixed rod 21 and a second elastic telescopic rod 22. The fixed rod 21 is arranged on the rear side of the support plate 1, and a movable groove is opened at the rear end. One end of the second elastic telescopic rod 22 is used to be fixed to the front end frame 5 of the car, and the other end is extended into the movable groove.

[0046] The support plate 1 is deformed after being hit, and drives the fixed rod 21 in the deformed area to move together. When the fixed rod 21 moves, it compresses the second elastic telescopic rod 22, and the second elastic telescopic rod 22 shrinks into the inside of the fixed rod 21, so that the length of the support member is shortened, so that the position where the support plate 1 is hit is deformed smoothly to absorb part of the impact energy. At the same time, the second elastic telescopic member 22 absorbs part of the impact energy through elastic potential energy to weaken the impact intensity, so that the pedestrian's legs are hit and the impact damage is reduced.

[0047] In the present invention, the fixing member includes a fixing rod 21 and a second elastic telescopic rod 22. Specifically, the fixing rod 21 is installed on the rear side of the support plate 1. In order to ensure the stability and reliability of the fixing rod 21, a movable groove is specially provided at its rear end portion. The function of the movable groove is to limit the moving range of the second elastic telescopic rod 22, thereby ensuring the stability and safety of the entire device. One end of the second elastic telescopic rod 22 is designed to be fixed on the front end frame 5 of the automobile. This structure enables the second elastic telescopic rod 22 to be firmly connected to the structure of the automobile, thereby providing sufficient supporting force. The other end of the second elastic telescopic rod 22 is extended into the aforementioned movable groove for setting. Through this setting method, the second elastic telescopic rod 22 can perform appropriate telescopic movement under the constraint of the movable groove to adapt to different usage environments and needs.

[0048] Furthermore, the second elastic telescopic rod 22 includes a movable rod 222 and an elastic member 221. One end of the movable rod 222 is used to be fixed to the front end frame 5 of the automobile, and the other end is extended into the movable groove. The elastic member 221 is arranged inside the movable groove and is located between the end of the movable rod 222 and the bottom of the movable groove.

[0049] One end of the movable rod 222 is designed to be firmly fixed on the front frame 5 of the automobile to ensure that it remains stable during the driving of the vehicle. The other end of the movable rod 222 extends into a specially designed movable groove. The setting of this movable groove is to ensure that the movable rod 222 does not exceed a predetermined range during the extension and retraction process, thereby ensuring the safety and reliability of the entire telescopic rod system. Specifically, the movable groove is a groove body with a specific shape and size, and the end of the movable rod 222 can be accommodated inside it. In order to further improve the stability and buffering performance of the system, the elastic member 221 is arranged inside the movable groove. The elastic member 221 is usually a material or structure with elasticity, such as an elastic Spring, rubber pad or other similar elastic elements, the function of the elastic member 221 is to provide a certain buffer and elastic support when the movable rod 222 is subjected to external force, thereby reducing the damage of the impact force to the entire system. The elastic member 221 is placed between the end of the movable rod 222 and the bottom of the movable groove, so that when the movable rod 222 is subjected to external force, the elastic member 221 can effectively absorb and disperse these forces to prevent the movable rod 222 from directly hitting the bottom of the movable groove, thereby avoiding possible damage or noise. In addition, the presence of the elastic member 221 can also enable the movable rod 222 to quickly return to its original position after being subjected to external force, thereby ensuring the stability and reliability of the entire telescopic rod system.

[0050] When the fixed rod 21 moves backward with the support plate 1, the internal elastic member 221 is compressed, and the movable rod 222 moves toward the inside of the fixed rod 21 to squeeze the elastic member 221. At the same time, the elastic member 221 pushes the fixed rod 21 and the movable rod 222 in the opposite direction through elastic potential energy, thereby offsetting part of the impact energy transmitted by the fixed rod 21 and the movable rod 221, thereby weakening the impact strength and reducing the impact damage to the pedestrian's legs.

[0051] When the elastic member 221 is a spring, the movable rod 222 is telescopically movable in the fixed rod 21 with the cooperation of the spring, so that when the support plate 1 moves backwards when hit, the impact energy is weakened by the elastic potential energy of the spring. At the same time, a rubber block is provided on the inner cavity wall of one end of the movable rod 222 facing the support plate 1 or on the side of the movable groove facing the movable rod 222 as a damper, so that the movable rod 222 collides with the rubber block or drives the rubber block to collide with the inner cavity wall of the movable groove during the movement, thereby avoiding resonance of the spring.

[0052] The movable rod 222 moves in the fixed rod 21 through the elastic member 221 to weaken the impact on the support plate 1. However, when the movable rod 222 moves over a long distance, it is easy to move to the outside of the fixed rod 21 and escape from the movable groove. Therefore, it is necessary to limit the movable distance of the movable rod 222. A limiting structure 23 is provided between the movable rod 222 and the fixed rod 21. The limiting structure 23 is used to limit the movable rod 222 from escaping from the movable groove. Specifically, in an embodiment of the present invention, a limiting structure 23 is provided between the movable rod 222 and the fixed rod 21. The limiting structure 23 is used to limit the movable rod 222 from escaping from the movable groove.

[0053] Furthermore, the limiting structure 23 includes a limiting member and a limiting groove 232 , and the limiting structure 23 includes a limiting groove 232 and a limiting protrusion 231 extending into the limiting groove 232 , and one of the limiting protrusion 231 and the limiting groove 232 is arranged on the movable rod 222 , and the other is arranged on the fixed rod 21 .

[0054] Specifically, the limit member can be any form of mechanical device, such as a protrusion or a groove, and its main function is to play a limiting role when the movable rod 222 moves to a specific position. The limit groove 232 is a structure that matches the limit member, usually a groove or a hole, which is used to receive the limit protrusion 231, thereby forming a predetermined range of motion between the movable rod 222 and the fixed rod 21. Through the limit structure 23, when the movable rod 222 reaches the position of the limit groove 232 during the movement, the limit member will enter the limit groove 232 to prevent the movable rod 222 from continuing to move, thereby ensuring that the movable rod 222 moves within a safe and predetermined range.

[0055] See also Figure 4 The present application also provides a vehicle, which includes a front bumper 4, a front end frame 5, a pedestrian leg impact protection structure and a front headlight 6, wherein the front end frame 5 is arranged behind the front bumper, and the front headlight 6 is arranged on the rear side of the support plate 1. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0056] The shape of the support plate 1 is set according to the shape of the front bumper 4. The support plate 1 can be set as a straight plate or an arc plate, so that the front bumper 4 can contact the support plate 1 after colliding with the legs of the pedestrian, and the support plate 1 can weaken the impact damage caused by the collision.

[0057] In order to ensure the safety of pedestrians, a certain distance is deliberately reserved between the support plate 1 and the headlight 6. Such a structure is to allow the support plate 1 to have a certain deformation space in the event of an accidental collision. When the support plate 1 is deformed after being impacted, the reserved distance can effectively prevent the legs of pedestrians from directly hitting the headlight 6. In this way, even in the unfortunate event of a collision, the legs of pedestrians will not suffer secondary injuries due to the collision with the hard headlight 6, thereby greatly reducing the risk of pedestrian injury. At the same time, the support plate 1 cooperates with the support member 2 to weaken the impact energy and gradually weaken the impact strength during the backward deformation process, so that the impact strength of the legs of pedestrians is weakened before contacting the headlight 6, thereby reducing the damage to the legs of pedestrians caused by the collision with the headlight 6 when the collision is too severe, and the telescopic length of the second elastic telescopic rod 22 can be limited, so that when the second elastic telescopic rod 22 is compressed to the shortest, the headlight 6 is still located on the rear side of the support plate 1, thereby reducing the possibility of pedestrian legs being injured by colliding with the headlight 6 during the collision.

[0058] The support plate 1 is installed at the rear side of the front bumper 4, which improves the overall strength and stability of the front bumper 4. Through this installation method, the possibility of damage to the front bumper 4 in the event of a collision or external force impact can be effectively reduced. In addition, the presence of the support plate 1 further enhances the buffering capacity of the front bumper 4, enabling it to better absorb and disperse the impact force when facing an unexpected collision. When a pedestrian unfortunately comes into contact with the front bumper 4 of the vehicle, the support plate 1 can significantly reduce the impact damage to the legs of the pedestrian, thereby improving the safety of the pedestrian to a certain extent. Specifically, in an embodiment of the present invention, a card slot is provided on the rear side of the front bumper 4, and a card connector is provided on the front side of the support plate 1. The card connector is carded in the card slot to fix the support plate 1 on the rear side of the front bumper 4.

[0059] In the rear area of ​​the front bumper 4, a slot structure for installation is provided, and the slot structure is intended to fix and connect the support plate 1. At the same time, the front end of the support plate 1 is also correspondingly designed and equipped with snap connectors. The shape and size of these snap connectors are adapted to the slot structure and can be smoothly embedded in the slot. Through this method, the snap connectors and the slot structure are closely matched to ensure that the support plate 1 is firmly installed on the rear side of the front bumper 4. The slot structure not only ensures the stability and reliability of the support plate 1, but also facilitates disassembly and replacement when necessary, thereby improving the overall convenience of maintenance and operation.

[0060] Furthermore, the length of the clamping member is greater than the depth of the clamping groove, so that a buffer gap is formed between the front bumper 4 and the support plate 1 .

[0061] A certain buffer gap is deliberately designed between the support plate 1 and the front bumper 4. Such a structure is intended to provide a buffer zone to unload force when an unexpected situation occurs in which the pedestrian's legs are hit. The existence of such a buffer gap enables the front bumper 4 to absorb part of the impact force when it hits the pedestrian's legs, thereby reducing the damage to the pedestrian. In addition, this structure also allows the pedestrian's legs to move a certain distance with the front bumper 4 after being hit. This movement can not only further reduce the impact force, but also reduce the secondary damage caused by being fixed. The structure of this buffer gap can not only effectively absorb the impact force, but also protect the safety of pedestrians to a certain extent and reduce the damage caused by the impact.

[0062] In order to ensure the stability of the support plate 1, it is necessary to install the support member 2 on the rear side of the support plate 1 on the front frame 5. Specifically, in the embodiment of the present invention, the support member 2 includes a fixed rod 21 and a second elastic telescopic rod 22. The fixed rod 21 is arranged on the rear side of the support plate 1, and a movable groove is opened at the rear end. The second elastic telescopic rod 22 includes a movable rod 222 and an elastic member 221. One end of the movable rod 222 is used to be fixed to the front frame 5, and the other end is extended into the movable groove. The elastic member 221 is arranged inside the movable groove and is located between the end of the movable rod 222 and the bottom of the movable groove.

[0063] A mounting piece corresponding to the movable rod 222 is convexly provided on the front side of the front end frame 5. The movable rod 222 is sleeved on the outside of the mounting piece, and a positioning pin is passed between the movable rod 222 and the mounting piece. The positioning pin is used to limit the movable rod 222 from being separated from the mounting piece.

[0064] On the front side of the front end frame 5, a group of mounting parts corresponding to the movable rod 222 are provided. These mounting parts are arranged at appropriate positions of the front end frame 5 so as to effectively cooperate with the movable rod 222. The movable rod 222 is sleeved on the outside of these mounting parts to form a tight connection structure. In order to ensure that the movable rod 222 does not accidentally detach from the mounting parts during use, a positioning pin is passed between the movable rod 222 and the mounting parts. The positioning pin not only fixes the position of the movable rod 222, but also effectively limits the possibility of the movable rod 222 detaching from the mounting parts, thereby significantly improving the stability and reliability of the entire front end frame 5, ensuring that the support plate 1 and the support part 2 can effectively play a role after the front bumper 4 collides with the legs of pedestrians, thereby weakening the impact strength and reducing the damage to the legs of pedestrians.

[0065] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
