Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a buffer support component. Additionally, this utility model also relates to a vehicle. Background Technology

[0002] Between sheet metal components with gaps, such as the hood and engine compartment frame, buffer supports are typically installed. The engine compartment frame serves as the base component, and the hood as the supported component. By installing the buffer supports onto the engine compartment frame, the hood is supported. Besides supporting the hood and maintaining proper clearance and flushness between the hood and surrounding components like headlights and the front bumper, the buffer supports also absorb energy when the hood is impacted by external objects, reducing the damage to the vehicle and pedestrians.

[0003] In existing technologies, buffer supports typically adopt a design in the form of buffer blocks. However, limited by the specific sealing gap space between the base component and the supported component, buffer blocks of a particular size are difficult to adapt to the installation space conditions of different vehicle models, thus limiting their versatility. Furthermore, the single support force setting of buffer blocks cannot meet diverse scenario requirements. For example, gentle support is needed when adjusting differences in the hood panel, while strong buffer support is required when the hood closes violently or under the vibrations of rough road conditions to ensure that the headlights and front bumper are protected from hood impact damage. Moreover, when a vehicle collides with a pedestrian, the single support performance of the buffer block cannot effectively protect the pedestrian, resulting in a high impact force from the hood to the pedestrian in a collision, leading to a higher injury coefficient. This safety issue urgently needs to be addressed. Utility Model Content

[0004] In view of this, the present invention aims to provide a buffer support to improve the buffering effect of the buffer support on the supported component.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A buffer support is provided for forming a support between a base member and a supported member that are spaced apart. The buffer support includes a base for connecting the base member, a support body for supporting the supported member, and an elastic buffer portion disposed between the base and the support body.

[0007] In the supporting direction of the buffer support, the elastic buffer portion maintains an elastic support state between the support body and the base, thereby mitigating the impact force from the support body.

[0008] Furthermore, in the supporting direction, the position of the support body on the elastic buffer is adjustable.

[0009] Furthermore, the elastic buffer includes a sliding sleeve guided and disposed on the base along the support direction, and an elastic body acting between the bottom of the sliding sleeve and the base; the support body is screwed onto the sliding sleeve, and turning the support body can adjust the position of the support body on the sliding sleeve in the support direction.

[0010] Furthermore, the support body includes a head for supporting the supported member and a connecting portion screwed onto the sliding sleeve; the head and / or the connecting portion are provided with cavities.

[0011] Furthermore, the base is provided with a sliding cavity with an open top, and the sliding sleeve is guided and disposed in the sliding cavity; the elastic body includes a spring disposed at the bottom of the sliding cavity, and the spring is elastically supported between the bottom of the sliding cavity and the sliding sleeve.

[0012] Furthermore, the elastomer also includes a rubber block disposed at the bottom of the sliding cavity, with a gap between the top of the rubber block and the bottom of the sliding sleeve.

[0013] Furthermore, the top opening of the sliding cavity is provided with an anti-detachment buckle, which restricts the sliding sleeve within the sliding cavity; and / or, the inner wall of the sliding cavity is provided with a guide groove, and the outer wall of the sliding sleeve is provided with a guide rib, which guides the sliding within the guide groove; and / or, the bottom of the sliding sleeve is provided with a positioning post, which is inserted into the spring.

[0014] Furthermore, the base includes a columnar main body and a mounting plate disposed around the main body, and the mounting plate is provided with a mounting clip on the side of the main body facing away from the support; when the main body is inserted into the mounting hole on the base member, the base member is clamped between the mounting plate and the mounting clip.

[0015] Furthermore, the mounting base plate and the main body are connected by a weak connecting rib.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] (1) The buffer support of this utility model is designed as a base, an elastic buffer part and a support body. By utilizing the elastic buffer performance of the elastic buffer part, the impact force of the collision borne by the supported part is transmitted to the elastic buffer part through the support body. Then, the elastic buffer part absorbs a large amount of impact force through elastic deformation, thereby playing a supporting and buffering role between the base and the supported part, which is conducive to improving the buffering effect of the buffer support on the supported part.

[0018] (2) By designing the support body on the elastic buffer section to be position-adjustable, the support dimension of the entire buffer support component in its support direction can be changed by adjusting the position of the support body on the elastic buffer section. This allows it to adapt to different interval size requirements between the base component and the supported component, thereby meeting different assembly interval size requirements between the base component and the supported component. When the base component is the engine compartment frame and the supported component is the engine hood, it can meet the support requirements of engine hoods of different vehicle models, thus greatly improving the versatility of the buffer support component.

[0019] (3) The elastic buffer part is designed as two parts: a sliding sleeve and an elastic body. The sliding sleeve adopts the form of guiding and sliding on the base, which provides a flexible and reliable foundation for the support body to be set on the sliding sleeve. Then, by utilizing the elastic support effect of the elastic body between the base and the sliding sleeve, sufficient elastic buffer performance of the elastic buffer part is ensured.

[0020] (4) The support body is designed as two parts: the head and the connecting part. By increasing the radial dimension of the head, the support contact area of ​​the support body on the supported part can be increased, thereby forming a more stable support for the supported part. The connecting part is provided with threads, which can be screwed into the sliding sleeve. Thus, by rotating and twisting the head, the height position of the support body on the sliding sleeve can be adjusted well.

[0021] (5) A sliding cavity with an open top is provided on the base, which can be conveniently inserted into the sliding cavity. The sliding cavity is set in a form that can slide up and down in the sliding cavity. The elastic body is set at the bottom of the sliding cavity in the form of a spring, which can form a good elastic support for the sliding cavity, so that the elastic buffer part can play a stable buffer support role.

[0022] (6) By placing a rubber block at the bottom of the sliding cavity and maintaining a certain gap between the top of the rubber block and the bottom of the sliding sleeve, the spring and the rubber block can play a buffering role in different compression buffering stages. In this way, the buffer support has two buffering sections with different elastic support forces. Taking the case where the buffer support is set between the engine hood and the engine compartment frame of the vehicle as an example, the spring can buffer the slight normal vibration of the engine hood under normal vehicle operation.

[0023] (7) Anti-detachment buckles are installed at the top opening of the sliding cavity. Utilizing the elastic deformation characteristics of the anti-detachment buckles, the sliding sleeve can open each anti-detachment buckle and be inserted into the sliding cavity. After insertion, the barbed head of the anti-detachment buckle can restrict the sliding sleeve within the sliding cavity, thereby effectively preventing the sliding sleeve from detaching from the sliding cavity. Guide grooves and guide ribs are correspondingly provided on the inner wall of the sliding cavity and the outer wall of the sliding sleeve. This can improve the smoothness of the sliding sleeve's guiding slide within the sliding cavity and effectively prevent the sliding sleeve from rotating arbitrarily within the sliding cavity, thus maintaining the support stability of the support body on the sliding sleeve. Multiple positioning posts are provided at the top of the sliding sleeve corresponding to each spring, which can realize the positioning of the spring and prevent the spring from tilting or skewing at the bottom of the sliding cavity, ensuring that the spring plays a stable elastic support role.

[0024] (8) The main body of the base is designed as a column to accommodate the installation requirements of the mounting holes on the base. By utilizing the snap-fit ​​action of the mounting base plate and the mounting clip on the main body, the base can be easily installed and fixed onto the base.

[0025] (9) By setting several weak connecting ribs between the mounting base and the main body to achieve the connection between the two, the connection strength between the main body and the mounting base can be reduced. In this way, when the engine hood is subjected to a strong external impact, the impact force is transmitted to the main body through the support and elastic buffer. Under the condition that the main body is subjected to a strong impact, the weak connecting ribs can break, causing the base to detach from the base component. With this connection structure, in the event of a vehicle collision with a pedestrian, the collapse and breakage of the weak connecting ribs can accelerate the collapse and deformation of the engine hood, thereby reducing the impact injury to the pedestrian and achieving the purpose of reducing the degree of impact injury to the pedestrian.

[0026] Another objective of this invention is to provide a vehicle equipped with the buffer support described herein. The vehicle of this invention possesses the technical advantages of the aforementioned buffer support. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] Example 1

[0048] This embodiment relates to a buffer support member, used to form a support between a spaced-apart base member 5 and a supported member 6, which can improve the buffering effect of the buffer support member on the supported member 6; an exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0049] Overall, the buffer support includes a base 1 for connecting the base 5, a support body 4 for supporting the supported member 6, and an elastic buffer portion disposed between the base 1 and the support body 4; in the support direction of the buffer support, the elastic buffer portion maintains an elastic support state between the support body 4 and the base 1, thereby mitigating the impact force from the support body 4.

[0050] It should be noted that, based on the above-mentioned overall design concept, the technical solution of this utility model can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the above-mentioned elastic buffer part can be a single component with its own elastic deformation performance, or it can be a split structure in which a sliding guide and an elastic component cooperate; the support body 4 can be fixed to the elastic buffer part, or it can be set on the elastic buffer part in an adjustable manner. The specific arrangement sequence and assembly method of the base 1, the elastic buffer part, and the support body 4 can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not involved in the above-mentioned overall setting, reasonable and flexible design can be carried out by referring to mature setting methods in the field and the actual situation during implementation. The specific implementation schemes described below in this embodiment are only one of the many solutions that can be formed by the above-mentioned combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many solutions that can be formed by the above-mentioned combinations and variations, as well as the specific implementation schemes of this embodiment, are all within the protection scope of this utility model.

[0051] Specifically, in this embodiment, the support body 4 is positioned adjustable on the elastic buffer section in the support direction of the buffer support. By designing the support body 4 to be position-adjustable on the elastic buffer section, the support dimension of the entire buffer support in its support direction can be changed by adjusting the position of the support body 4 on the elastic buffer section. This allows it to adapt to different interval size requirements between the base component 5 and the supported component 6, thereby meeting different assembly interval sizes between the base component 5 and the supported component 6. When the base component 5 is an engine compartment frame and the supported component 6 is an engine hood, it can meet the support requirements of engine hoods for different vehicle models, thus greatly improving the versatility of the buffer support.

[0052] For the design of the elastic buffer section, a split structure is preferred. For example... Figure 3 and combined Figure 4As shown, the elastic buffer in this embodiment includes a sliding sleeve 2 guided and disposed on a base 1 along the support direction, and an elastic body 3 acting between the bottom of the sliding sleeve 2 and the base 1. A support body 4 is screwed into an adjusting screw hole 20 on the sliding sleeve 2. Tightening the support body 4 allows adjustment of its position on the sliding sleeve 2 in the support direction. The elastic buffer is designed with two parts: the sliding sleeve 2 and the elastic body 3. The sliding sleeve 2, which slides along the base 1, provides a flexible and reliable foundation for the support body 4. The elastic body 3, acting as an elastic support between the base 1 and the sliding sleeve 2, ensures sufficient elastic buffering performance. Based on this, by screwing the support body 4 onto the sliding sleeve 2 and rotating it to change its screw depth, the position of the support body 4 on the elastic buffer can be effectively adjusted, thereby changing the support height of the buffer support and thus effectively improving the versatility of the buffer support.

[0053] Preferably, such as Figure 5 , Figure 6 As shown, the support body 4 adopts the following structural scheme. In this embodiment, the support body 4 includes a head 40 for supporting the supported member 6, and a connecting portion 41 screwed onto the sliding sleeve 2; furthermore, a cavity 42 can be provided in the head 40 or the connecting portion 41. By designing the support body 4 as two parts, the head 40 and the connecting portion 41, the radial dimension of the head 40 is increased, thereby increasing the support contact area of ​​the support body 4 on the supported member 6, thus better forming a stable support for the supported member 6; the connecting portion 41 is provided with threads, enabling screwing into the sliding sleeve 2, thereby allowing for good adjustment of the height position of the support body 4 on the sliding sleeve 2 by rotating and turning the head 40. Providing a cavity 42 inside the head 40 or the connecting portion 41 not only saves on the manufacturing materials of the support body 4 but also helps to reduce the weight of the support body 4 itself.

[0054] To ensure a smooth and guideable sliding configuration of the sliding sleeve 2 on the base 1, it is still as follows Figure 4 and combined Figure 5 , Figure 6 As shown, the base 1 has a top-opening sliding cavity 100, and the sliding sleeve 2 is guided and disposed within the sliding cavity 100. The elastic body 3 includes a spring 30 disposed at the bottom of the sliding cavity 100, and the spring 30 elastically supports the bottom of the sliding cavity 100 and the sliding sleeve 2. The top-opening sliding cavity 100 on the base 1 allows the sliding sleeve 2 to be easily inserted into the sliding cavity 100, and the sliding sleeve 2 is designed to slide up and down within the sliding cavity 100. By placing the elastic body 3 at the bottom of the sliding cavity 100 and using the spring 30, good elastic support can be formed for the sliding sleeve 2, thereby enabling the elastic buffer part to play a stable buffering support role.

[0055] Based on the above configuration, the elastic body 3 in this embodiment also includes a rubber block 31 disposed at the bottom of the sliding cavity 100, with a gap between the top of the rubber block 31 and the bottom of the sliding sleeve 2. By placing the rubber block 31 at the bottom of the sliding cavity 100 and maintaining a certain gap between the top of the rubber block 31 and the bottom of the sliding sleeve 2, the spring 30 and the rubber block 31 can respectively play a buffering role in different compression buffering stages. In this way, the buffer support has two buffering sections with different elastic support forces. Taking the case where the buffer support is disposed between the engine hood and the engine compartment frame of a vehicle as an example, the spring 30 can buffer the slight normal vibration of the engine hood under normal vehicle operation conditions. When the vehicle is traveling on bumpy roads, the vibration amplitude of the engine hood increases, and the buffering effect of the spring 30 is insufficient to completely alleviate the compressive impact of the engine hood. In this case, the top of the rubber block 31 will abut against the sliding sleeve 2, exerting a greater buffering effect.

[0056] In practical implementation, three springs 30 and three rubber blocks 31 can be installed at the bottom of the sliding cavity 100, with the springs 30 and rubber blocks 31 arranged alternately around the center of the bottom of the sliding cavity 100. Specifically, in the natural state where the buffer support is not compressed, the distance D between the top of the rubber block 31 and the bottom of the sliding sleeve 2 (e.g., ...) Figure 6 (As shown in the image) can be set to around 2mm.

[0057] In this way, the rubber block 31 and the spring 30 can play a buffering role under different compression stages and impact forces. The curve showing the impact compression force of the engine hood on the buffer support and the stroke of the buffer support under compression is as follows: Figure 7 As shown. When the compression stroke reaches 2mm, the rubber block 31 begins to function, the curvature of the curve changes, and the cushioning strength increases significantly. Figure 7 The arrow in the middle of the curve indicates the position where the compression stroke is 2mm. At this point, the bottom of the sliding sleeve 2 abuts against the rubber block 31. The curvature of the curve changes thereafter, indicating a significant change in the buffering force of the buffer support. In the initial compression stroke between 0 and 2mm, the compressive force (i.e., the supporting force) is provided solely by the spring 30, and the force increases linearly. However, in the subsequent compression stroke (i.e., the curve after the position indicated by the arrow in the figure), the buffering support force is provided by the rubber block 31, and the curve of the supporting force begins to increase rapidly until the weak connecting rib 120 breaks.

[0058] Furthermore, an anti-detachment buckle 102 is provided at the top opening of the sliding cavity 100. The specific number of anti-detachment buckles 102 can be one or more. In this embodiment, three anti-detachment buckles 102 are provided at the opening of the sliding cavity 100, and the three anti-detachment buckles 102 are evenly distributed around the circumference of the main body 10 of the base 1. In this way, the anti-detachment buckles 102 can confine the sliding sleeve 2, which is inserted into the sliding cavity 100, within the sliding cavity 100. By providing the anti-detachment buckles 102 at the top opening of the sliding cavity 100, the elastic deformation characteristics of the anti-detachment buckles 102 allow the sliding sleeve 2 to open and insert into the sliding cavity 100. After insertion, the barbed head of the anti-detachment buckle 102 can confine the sliding sleeve 2 within the sliding cavity 100, thereby effectively preventing the sliding sleeve 2 from detaching from the sliding cavity 100.

[0059] In addition, a guide groove 101 can be provided on the inner wall of the sliding cavity 100, and a guide rib 21 can be provided on the outer wall of the sliding sleeve 2. The guide rib 21 guides the sliding within the guide groove 101. Providing the guide groove 101 and the guide rib 21 on the inner wall of the sliding cavity 100 and the outer wall of the sliding sleeve 2 can improve the smoothness of the sliding within the sliding cavity 100 and effectively prevent the sliding sleeve 2 from rotating randomly within the sliding cavity 100, so as to maintain the support stability of the support body 4 on the sliding sleeve 2.

[0060] For the spring 30 located below the sliding sleeve 2, a corresponding number of positioning posts 22 can be set at the bottom of the sliding sleeve 2, and the positioning posts 22 can be inserted into the corresponding spring 30. The top of the sliding sleeve 2 is provided with multiple positioning posts 22 corresponding to each spring 30, which can realize the positioning of the spring 30, prevent the spring 30 from tilting or tilting at the bottom of the sliding cavity 100, and ensure that the spring 30 plays a stable elastic support role.

[0061] Regarding the specific configuration of the base 1, there are naturally many different structural options available; for example, the base 1 can be designed as a cube or a cylinder. In this embodiment, as... Figure 4 and Figure 8 As shown, the base 1 includes a columnar main body 10 and a mounting base 11 surrounding the main body 10; and a mounting clip 103 is provided on the side of the main body 10 facing away from the support body 4 on the mounting base 11. When the main body 10 is inserted into the mounting hole 50 on the base member 5, the mounting clip 103 can retract inward and pass through the mounting hole 50 on the base member 5 by its own elastic deformation capability; when the base 1 is inserted into the base member 5, the base member 5 is clamped between the mounting base 11 and the mounting clip 103, thereby completing the installation and fixation of the base 1 on the base member 5. Preferably, three mounting clips 103 can be provided at intervals in the circumferential direction of the main body 10, which cooperate with the annular mounting base 11 above them to realize the installation of the base 1 on the base member 5.

[0062] The main body 10 of the base 1 is designed as a column to accommodate the installation requirements of the mounting holes 50 on the base component 5. By utilizing the snap-fit ​​action of the mounting base plate 11 and the mounting clip 103 on the main body 10, the base 1 can be easily installed and fixed onto the base component 5.

[0063] At the same time, combined Figure 9 As shown, multiple anti-rotation protrusions 104 can be provided on the main body 10, and a corresponding number of anti-rotation notches 51 can be provided on the side of the mounting hole 50 of the base 5. When the base 1 is inserted, each anti-rotation protrusion 104 is inserted into the anti-rotation notch 51, which can prevent the base 1 from rotating freely on the base 5.

[0064] Regarding the connection method between the mounting substrate 11 and the main body 10, the plate of the mounting substrate 11 can be extended inward and connected to the outer peripheral surface of the main body 10 as a whole; or multiple arc-shaped holes can be reserved between the annular mounting substrate 11 and the peripheral surface of the main body 10, thereby forming a weak connecting rib 120 between each arc-shaped hole; so that the mounting substrate 11 and the main body 10 are connected by the weak connecting rib 120.

[0065] like Figure 4 and Figure 8 As shown, by providing several weak connecting ribs 120 between the mounting base 11 and the main body 10 to achieve the connection between the two, the connection strength between the main body 10 and the mounting base 11 can be reduced. Thus, when the hood is subjected to a strong external impact, the impact force is transmitted to the main body 10 through the support 4 and the elastic buffer. Under strong impact, the weak connecting ribs 120 can break, causing the base 1 to detach from the base member 5. The aforementioned weak connecting ribs 120 can also be called collapse ribs, referring to structures that yield and lose their support or connection capacity when subjected to extreme pressure or loads exceeding their bearing capacity. This connection structure, in the event of a vehicle collision with a pedestrian, utilizes the collapse and breakage of the weak connecting ribs 120 to accelerate the collapse and deformation of the hood, thereby reducing impact injuries to pedestrians and achieving the goal of reducing the degree of pedestrian impact damage.

[0066] In summary, the buffer support in this embodiment is designed as a base 1, an elastic buffer part, and a support body 4. Utilizing the elastic buffer performance of the elastic buffer part, the impact force borne by the supported member 6 is transmitted to the elastic buffer part through the support body 4. The elastic buffer part then absorbs a large amount of impact force through elastic deformation, thereby playing a supporting and buffering role between the base member 5 and the supported member 6, which is beneficial to improving the buffering effect of the buffer support on the supported member 6.

[0067] Example 2

[0068] This embodiment relates to a vehicle equipped with the buffer support member provided in Embodiment 1. Of course, the aforementioned buffer support member can be disposed between spaced panels throughout the vehicle, providing support and buffering between the panels; preferably, the buffer support member can be disposed between the engine compartment frame and the engine hood in the front engine compartment of the vehicle. By providing the buffer support member, the vehicle possesses the technical advantages of the buffer support member listed in Embodiment 1.

[0069] Compared to commercially available buffer blocks, most are injection-molded from a single piece of rubber. As aftermarket components, their rigidity determines their support performance, and once installed, the support height (i.e., the distance between the base component 5 and the supported component 6) cannot be adjusted. Furthermore, the fixed stiffness of existing buffer blocks prevents dynamic changes in rigidity, thus hindering their adaptive buffering performance. Under normal vibrations of the vehicle's hood or during abnormal external collisions, the buffer block's support strength and buffering performance remain unchanged, significantly reducing its effectiveness.

[0070] It is evident that existing buffer blocks have limited versatility, offer only one type of support, and are difficult to adapt to changes in scenarios. Especially in abnormal situations such as severe collisions or adverse road conditions, they cannot ensure adequate cushioning of the hood, and the hood may collide with the headlights, bumpers, etc. In the event of a pedestrian collision, inadequate protection for pedestrians may result in serious injury.

[0071] The above description is merely a preferred embodiment of this utility model. Detailed explanations of configurations, examples of specific structural arrangements, and descriptions of assembly and connection methods are provided to ensure sufficient disclosure so that those skilled in the art can better implement this utility model, and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
