For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Reference below Figure 1-Figure 6 A buffer member 100 according to an embodiment of the present invention is described.

[0034] like Figure 1-Figure 6 As shown, the buffer 100 according to the embodiment of the utility model includes: a connecting portion 10 and a deformable elastic portion 20, the side wall of the connecting portion 10 has a thread, so that the connecting portion 10 is threadedly connected to a component, which is conducive to the installation of the buffer 100, and the elastic portion 20 is arranged at one end of the connecting portion 10 (such as Figure 1 The elastic portion 20 is connected to the connecting portion 10, and the end of the elastic portion 20 away from the connecting portion 10 (as shown in the figure) Figure 1 The lower end as shown in the figure can abut against another component, so that when the two components are close to each other, the elastic portion 20 is compressed and deformed to absorb energy, thereby preventing the two components from being damaged or deformed due to mutual impact.

[0035] The end of the elastic portion 20 away from the connecting portion 10 (such as Figure 1 The lower end of the elastic part 20 is partially recessed to form an escape groove 21, which is conducive to the full deformation of the elastic part 20. That is, after the elastic part 20 is compressed, at least a part of the elastic part 20 is squeezed into the escape groove 21 to disperse the stress, which can prevent the compressed end of the elastic part 20 (such as Figure 1The stress at the lower end (as shown) is too concentrated, which reduces the probability of the elastic portion 20 being damaged due to multiple compression deformations, and can increase the service life of the buffer 100.

[0036] According to the buffer 100 of the embodiment of the utility model, the buffer 100 is arranged between two components, and a deformable elastic part 20 is provided at the end of the buffer 100, so that the elastic part 20 can be compressed and deformed when the two components are close to each other, so as to absorb the energy generated by the mutual impact of the two components, and prevent the two components from being damaged or deformed due to the mutual impact; by providing an avoidance groove 21 at the compressed end of the elastic part 20, the avoidance groove 21 can provide a space margin for the deformation of the elastic part 20, which is conducive to the full deformation of the elastic part 20, and the energy absorption effect of the elastic part 20 can be improved. At the same time, it can prevent the stress of the elastic part 20 from being too concentrated, reduce the probability of the elastic part 20 being damaged due to multiple compression deformation, and improve the service life of the buffer 100.

[0037] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the avoidance groove 21 includes a plurality of avoidance grooves 21, which are arranged at intervals along the circumference of the elastic part 20, which can improve the uniformity of the compression deformation of the elastic part 20 and prevent the elastic part 20 from being damaged due to stress concentration. The elastic part 20 includes a bottom wall 201 and a side wall 202. The end of the elastic part 20 away from the connecting part 10 (such as Figure 2 The bottom wall 201 is formed at the lower end of the bottom wall 201, and the side wall 202 surrounds the bottom wall 201, and the side wall 202 is located on one side of the bottom wall 201 close to the connecting portion 10 (as shown in FIG. Figure 2 A plurality of avoidance grooves 21 may be provided on the bottom wall 201 of the elastic portion 20, which is beneficial for the elastic portion 20 to fully deform after being compressed.

[0038] Of course, multiple avoidance grooves 21 can be interconnected to form an annular avoidance groove 21 on the bottom wall 201, which can improve the uniformity of the compressive deformation of the elastic part 20 and improve the dispersion effect of the stress generated by the compression of the elastic part 20; further, the number of avoidance grooves 21 can be more, so as to form multiple annular avoidance grooves on the bottom wall 201 of the elastic part 20, and the multiple annular avoidance grooves 21 are arranged in sequence; in addition, the multiple avoidance grooves 21 can also be evenly distributed on the bottom wall 201 of the elastic part 20, that is, the multiple avoidance grooves 21 are evenly distributed on the bottom wall 201 of the elastic part 20.

[0039] In some examples, the plurality of avoidance grooves 21 may extend to the bottom wall 201 and the side wall 202 of the elastic portion 20, respectively. Figure 1 and Figure 2As shown, the avoidance groove 21 can be arranged at the junction edge of the bottom wall 201 and the side wall 202, which can increase the opening size of the avoidance groove 21, increase the space margin required for the elastic part 20 to be compressed and deformed, and enable the elastic part 20 to move outward (such as Figure 2 The outer side as shown in the figure is deformed, thereby ensuring that the elastic part 20 can fully deform and absorb energy after being compressed, thereby improving the dispersion effect of the stress generated by the elastic part 20 being compressed, and improving the service life of the buffer 100.

[0040] like Figure 2 As shown, in some examples, the avoidance groove 21 includes a first side surface 211, a second side surface 212 and a bottom surface 213. The first side surface 211 and the second side surface 212 are arranged relative to each other, so that the first side surface 211 and the second side surface 212 can be close to each other when the elastic part 20 is compressed and deformed, and the stress at the compressed end surface of the elastic part 20 can be dispersed; the bottom surface 213 is opposite to the opening of the avoidance groove 21, and the bottom surface 213 is respectively connected to the first side surface 211 and the second side surface 212, so that the bottom surface 213 can be toward the outside of the opening (such as Figure 2 The outer side as shown in the figure) can disperse the stress at the compressed end surface of the elastic part 20.

[0041] In which, along the direction away from the bottom surface 213 of the elastic portion 20 (such as Figure 2 As shown in the direction from inside to outside, the first side surface 211 and the second side surface 212 extend obliquely in the direction away from each other, which can increase the opening size of the avoidance groove 21 and increase the space margin required for the elastic part 20 to be compressed and deformed, thereby preventing the first side surface 211 and the second side surface 212 from squeezing each other after the elastic part 20 is compressed and deformed, reducing the probability of the elastic part 20 being damaged due to multiple compression deformations, thereby delaying the aging speed of the elastic part 20 and increasing the service life of the buffer 100.

[0042] like Figure 2 As shown, in some examples, the elastic portion 20 may be a cylinder, and the first side surface 211 and the second side surface 212 are respectively along the radial direction of the elastic portion 20 (eg Figure 2 The first side surface 211 and the second side surface 212 extend in a direction away from the bottom surface 213 (as shown in the inner and outer directions). Figure 2 The elastic portion 20 is separated from each other in the direction from inside to outside as shown in the figure, and the processing is facilitated based on increasing the space margin required for the elastic portion 20 to be compressed and deformed.

[0043] like Figure 1 and Figure 2 As shown, in some examples, the elastic portion 20 is moved in a direction away from the connecting portion 10 (eg Figure 2The connecting portion 10 extends in the direction from top to bottom as shown, thereby preventing the connecting portion 10 from interfering with another component based on the connection between the connecting portion 10 and a component, reducing the probability of the connecting portion 10 being damaged by pressure, and ensuring that the elastic portion 20 can smoothly press against the other component when the two components are close to each other, so that the elastic portion 20 can deform normally to absorb energy, and at the same time is beneficial to improving the stability of the buffer 100 in supporting the two components.

[0044] The extension direction of the bottom surface 213 is inclined to the extension direction of the elastic portion 20 (eg Figure 2 For example, in the direction from top to bottom, the bottom surface 213 is facing away from the opening (such as Figure 2 The side of the avoidance groove 21 close to the bottom wall 201 of the buffer member 100 (such as Figure 2 The space of the lower side shown in the figure is beneficial to the end of the elastic part 20 (such as the lower side) based on improving the dispersion effect of the stress generated by the elastic part 20 under pressure. Figure 2 The lower end shown in the figure is fully deformed after being compressed, which can improve the cushioning effect of the two components.

[0045] It is understandable that if Figure 2 As shown, the bottom surface 213 can be a straight inclined surface for easy processing; or, the bottom surface 213 includes a plurality of planes, for example, the bottom surface 213 includes two planes, the two planes are perpendicular to each other, and the extension direction of one of the planes is the same as the extension direction of the elastic portion 20 (such as Figure 2 Of course, the bottom surface 213 may also be inward (such as Figure 2 The concave curved surface (from the outside to the inside as shown) can improve the guiding effect on the deformation of the elastic part 20, which is beneficial for the elastic part 20 to deform into the avoidance groove 21 after being compressed, can improve the deformation energy absorption capacity of the elastic part 20, and can improve the dispersion effect of the stress generated by the elastic part 20 being compressed.

[0046] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the buffer 100 also includes: a limit member 30, which is arranged on the side wall of the connecting portion 10, and the limit member 30 can be connected to the connecting portion 10, at least a portion of the limit member 30 protrudes from the side wall of the connecting portion 10, and then in the process of threaded connection between the connecting portion 10 and a component, the limit member 30 can abut against the component to limit the length of the buffer 100 exposed from the component, thereby when the buffer 100 abuts against another component, the limit member 30 can limit the distance between the two components to achieve support for the two components.

[0047] It can be understood that the number of buffer components 100 can include multiple, multiple buffer components 100 are symmetrically arranged, and the limiting component 30 limits the buffer component 100, which can improve the consistency of the distance between the two components at the relative positions, prevent the two components from shaking relative to each other, and improve the stability of the buffer component 100 supporting the two components.

[0048] In some examples, the limit member 30 can be integrally formed with the connecting portion 10 for ease of processing and can improve the structural strength of the connection between the limit member 30 and the connecting portion 10, thereby preventing the limit member 30 from breaking when the two components impact each other, thereby improving the service life of the buffer 100. By measuring the dimensions of different components, for example, by obtaining the dimensional data of the engine hood 200 and the engine compartment of different vehicle models, the position layout of the limit member 30 can be changed, and then a plurality of buffer members 100 can be processed to adapt to different vehicle models.

[0049] It can be understood that the stopper 30 of different buffer members 100 is arranged in the extension direction of the connecting portion 10 (eg Figure 2 The positions in the up and down directions (as shown) can be different, so that when different buffer members 100 are threadedly connected to a component at the connecting portion 10, the lengths exposed from the component can be different, so that the product can be adapted to a variety of vehicle models and the processing cost can be reduced.

[0050] In some examples, the limiting member 30 can be detachably connected to the connecting portion 10, which is convenient for replacing the limiting member 30, and is conducive to the application of the buffer member 100 to various models of vehicles. For example, the limiting member 30 can be a limiting column, which has a simple structure and low cost, and the side wall of the connecting portion 10 can have a plurality of limiting grooves, and the plurality of limiting grooves are arranged along the extension direction of the connecting portion 10 (such as Figure 2 The limiting columns can be arranged at intervals in the upper and lower directions as shown, and the limiting columns can be plugged into and matched with the limiting grooves to achieve fixation of the limiting columns, or the limiting columns can be threadedly connected to the limiting grooves to improve the fixation effect of the limiting columns.

[0051] Among them, the length of the limiting column is greater than the depth of the limiting groove, and after the limiting column is inserted into the limiting groove, a part of the limiting column is exposed from the limiting groove, and the part of the limiting column exposed from the limiting groove can press against a component when the buffer 100 is threadedly connected to the component, so as to achieve the limitation of the buffer 100.

[0052] It can be understood that by first disengaging the limit member 30 from one limit groove and then plugging the limit member 30 into another limit groove, the position of the limit member 30 on the buffer member 100 can be changed, and the operation is convenient. Furthermore, by processing one buffer member 100, it can be adapted to different vehicle models, which can reduce the processing cost.

[0053] like Figure 1As shown, according to some embodiments of the present invention, the connecting portion 10 has a positioning column 11, and the positioning column 11 is arranged at one end of the connecting portion 10 away from the elastic portion 20 (such as Figure 1 The upper end shown in the figure) allows the positioning column 11 to cooperate with a component before the connecting portion 10 is threadedly connected to the component, so that the buffer 100 can be positioned, which is convenient for operation.

[0054] The cross-sectional area of ​​the positioning column 11 in the direction away from the elastic portion 20 (eg Figure 1 That is, the side wall 202 of the positioning column 11 gradually decreases in the direction from bottom to top (as shown in the figure). Figure 1 The positioning post 11 extends from the outside to the inside (as shown), and then after contacting a component, the positioning post 11 can guide the movement direction of the entire buffer 100, making it easier for the connecting portion 10 to be threadedly connected to the component, thereby improving the positioning effect of the buffer 100.

[0055] In some examples, the elastic part 20 can be made of a flexible material such as rubber or silicone, which is beneficial to the deformation and energy absorption of the elastic part 20, and the elastic part 20 can be sleeved on the lower end of the connecting part 10 to achieve the connection between the elastic part 20 and the connecting part 10, and the elastic part 20 can be interference fit with the connecting part 10, which can improve the stability of the connection between the elastic part 20 and the connecting part 10; of course, the elastic part 20 can be integrally formed with the connecting part 10, that is, the entire buffer 100 can be made of a flexible material such as rubber or silicone.

[0056] like Figure 1-Figure 6 As shown, the vehicle according to the embodiment of the utility model includes an engine hood 200, an engine compartment and a buffer 100. The connecting portion 10 of the buffer 100 can be threadedly connected to the engine hood 200, and the elastic portion 20 of the buffer 100 can abut against the engine compartment when the engine hood 200 closes the engine compartment, thereby supporting the engine hood 200. The buffer 100 can absorb the energy generated when the engine hood 200 closes the engine compartment, and after the engine hood 200 closes the engine compartment, the buffer 100 can attenuate the impact force between the engine hood 200 and the engine compartment during vehicle bumps, which is beneficial to improving the stability of the vehicle.

[0057] Alternatively, the connection portion 10 of the buffer member 100 may be threadedly connected to the engine compartment, and the elastic portion 20 of the buffer member 100 may abut against the engine cover 200 when the engine cover 200 closes the engine compartment.

[0058] According to the vehicle of the embodiment of the utility model, the above-mentioned buffer component 100 can absorb the energy generated when the engine hood 200 closes the engine compartment, and after the engine hood 200 closes the engine compartment, the buffer component 100 can attenuate the impact force between the engine hood 200 and the engine compartment during vehicle bumps, which can reduce the probability of deformation of the engine hood 200 and the probability of damage to components in the engine compartment, which is beneficial to improving the stability of the vehicle and increasing the service life of the vehicle.

[0059] like Figure 3-Figure 6 As shown, according to some embodiments of the utility model, the engine hood 200 may have a hood bracket 210, which is connected to the engine hood 200, and a cavity is defined between the hood bracket 210 and the engine hood 200, and the hood bracket 210 has a threaded hole so that the connecting portion 10 of the buffer member 100 is threadedly connected to the hood bracket 210, and the connecting portion 10 extends into the cavity through the threaded hole, so that the hood bracket 210 can share the stress of the engine hood 200 and prevent the connecting portion 10 from damaging the engine hood 200 due to direct contact with the engine hood 200.

[0060] The engine compartment has a compartment bracket 300. When the engine cover 200 closes the engine compartment, the elastic portion 20 of the buffer 100 presses against the compartment bracket 300 to absorb the energy generated when the engine cover 200 closes the engine compartment, and the compartment bracket 300 may have a support pad 310. The support pad 310 may be made of a flexible material such as rubber or silicone. Then, when the engine cover 200 closes the engine compartment, the elastic portion 20 presses against the support pad 310, and both the elastic portion 20 and the support pad 310 deform to absorb energy. On the one hand, the deformation of the support pad 310 can improve the absorption effect of the energy generated by the mutual impact between the engine cover 200 and the engine compartment. On the other hand, the deformation of the support pad 310 can share the stress for the elastic portion 20, thereby improving the service life of the buffer 100.

[0061] In some examples, the number of buffer members 100 may be two, and taking the left and right directions of the vehicle as an example, the two buffer members 100 are relatively arranged on the left and right sides of the engine hood 200, and the limit member 30 can limit the buffer member 100 during the installation of the buffer member 100, so that the lengths of the parts of the two buffer members 100 exposed from the engine hood 200 remain consistent, and then after the engine hood 200 closes the engine compartment, the heights of the left and right sides of the engine hood 200 remain consistent, which can reduce the probability of the engine hood 200 shaking and improve the stability of the engine hood 200.

[0062] Other components and operations of the vehicle according to the embodiment of the utility model are known to those skilled in the art and will not be described in detail here. In the description of the utility model, "first feature" and "second feature" may include one or more of the features. Among them, the up-down direction, left-right direction and front-back direction are based on the up-down direction, left-right direction and front-back direction shown in the figure.
