Description

Technical Field

[0001] This application belongs to the technical field of seat shock absorption, specifically relating to a seat fixed shock absorption structure and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, consumers are increasingly demanding higher levels of vehicle comfort. As a crucial component of the passenger space, the seat's shock absorption performance directly impacts passenger comfort. Because seats are typically rigidly connected to the vehicle body or to the floor, vibrations from the vehicle are directly transmitted to the seat, thus affecting passenger comfort.

[0003] To enhance passenger comfort, some vehicle models use bolts to secure the seats to the vehicle body or to mounting points on the vehicle body. Rubber covers are then fitted over the bolts to absorb vibrations transmitted from the vehicle body to the seats, thus improving passenger comfort. However, since the seat frame is typically made of sheet metal, the edges of the bolt holes are often sharp, which can damage the rubber covers and thus affect their lifespan.

[0004] To ensure the lifespan of the rubber body, a common approach is to cover it with a metal bushing. This bushing isolates the rubber body from the holes and corners of the seat frame. While this prevents damage to the rubber body from the holes and corners of the seat frame, the friction between the metal bushing and the seat frame and the vehicle body generates noise, thus affecting the passenger's riding experience. It also increases the number of parts required for seat installation, thereby reducing installation efficiency. Utility Model Content

[0005] This application provides a seat fixing and shock absorption structure to improve seat installation efficiency and enhance passenger riding experience.

[0006] The technical solution adopted in this application is as follows:

[0007] A seat fixing and shock absorption structure includes bolts passing through a seat frame and a vehicle body or base, nuts threaded to the bolts, and two shock absorbers. Each shock absorber includes a flexible elastomer sleeved outside the bolt and a bracket disposed on the flexible elastomer. Each flexible elastomer includes a first shock absorber portion located outside the seat frame and a second shock absorber portion extending into the seat frame. Each bracket includes a body disposed on the first shock absorber portion and an extension portion disposed on the outside of the second shock absorber portion. The extension portion extends from the inside of the body in a direction away from the axial elastomer. Both the side of the body opposite to the first shock absorber portion and the side of the extension portion opposite to the second shock absorber portion have plastic contact layers.

[0008] By adopting the above technical solution, when fixing the seat using the seat fixing and shock absorption structure of this application, firstly, two shock absorbers are installed on the seat frame so that the second shock absorber on the two flexible elastomers extends into the holes of the seat frame, and the first shock absorber of the two flexible elastomers is located on both sides of the seat frame, and the two brackets are located at both ends of the hole structure on the seat frame. Then, the seat is moved to the required installation position so that the hole structure on the seat frame is aligned with the hole structure on the vehicle body or the hole structure on the foot of the vehicle body. At the same time, the first shock absorber at the bottom of the seat frame abuts against the vehicle body or the foot. Then, the bolts are installed so that the bolts pass through the hole structure on the seat frame and the hole structure on the vehicle body or the hole structure on the foot. Finally, the nuts are installed so that the nuts are threaded together with the bolts, and the nuts are used to apply pressure to the shock absorbers to fix the seat to the vehicle body or to the foot of the vehicle body.

[0009] When a vehicle vibrates, the seat is mounted on the vehicle body or the ground using the seat fixing and shock absorption structure described in this application. The vibration of the vehicle body is directly transmitted to the flexible elastomer or transmitted to the flexible elastomer through the ground, thereby allowing the flexible elastomer to absorb the vibration and isolate the vibration of the vehicle body from the seat frame. This prevents the seat from vibrating and improves passenger comfort.

[0010] Since the main body is located on the first shock absorber and the extension is located on the outside of the second shock absorber, the extension extends from the inside of the main body in a direction away from the first shock absorber. This allows the flexible elastomer to contact the corners of the holes in the seat frame through the bracket after the shock absorber is installed. This prevents the corners of the holes in the seat frame from damaging the flexible elastomer, thus ensuring the service life of the flexible elastomer. At the same time, it avoids the situation where the connection stability between the seat and the vehicle body or the ground is affected due to the damage to the flexible elastomer, thereby ensuring the connection stability between the seat and the vehicle body or the ground.

[0011] Furthermore, since both the side of the main body away from the first shock absorber and the side of the extension away from the second shock absorber have plastic contact layers, the bracket can contact the seat frame through the plastic contact layers to avoid noise caused by friction between the bracket and the seat frame, thereby improving the passenger's riding experience.

[0012] Furthermore, since the bracket is located on a flexible elastomer, when installing the shock absorber, only the flexible elastomer needs to be installed so that the bracket can be attached to the flexible elastomer and installed onto the seat frame. This avoids the need to install the flexible elastomer and the bracket separately, thereby reducing the number of parts required for fixing the seat and improving the installation efficiency of the seat.

[0013] Optionally, the first damping part is a ring structure, and multiple second damping parts are arranged at intervals along the circumference of the first damping part, and an insertion space for accommodating another flexible elastomer is formed between two adjacent second damping parts.

[0014] By adopting the above technical solution, since the first shock absorber is a ring structure, the absorption effect of the flexible elastomer on the axial vibration of the bolt can be improved, so as to further isolate the vibration transmitted in the axial direction of the bolt, thereby further ensuring the passenger's riding comfort.

[0015] Furthermore, since multiple second shock absorbers are spaced apart along the circumference of the first shock absorber, and an insertion space for another flexible elastomer is formed between two adjacent second shock absorbers, the structures of the two shock absorbers are identical, allowing them to be manufactured from the same mold, thus reducing the production cost of the shock absorbers and consequently the production cost of the seat fixed shock absorption structure. On the other hand, the two shock absorbers can be staggered and cross-fitted, so that the second shock absorber can completely wrap around the bolt as much as possible in the circumferential direction of the bolt, thereby ensuring the shock absorption effect of the second shock absorber on the radial direction of the bolt, further isolating the vibration transmitted in the radial direction of the bolt, and thus further ensuring the passenger's riding comfort.

[0016] Meanwhile, since there may be tolerances in the manufacturing of shock absorbers, multiple second shock absorbers are arranged at intervals along the circumference of the first shock absorber. This makes it easier for the second shock absorber to deform radially in the bolt, thus avoiding the situation where the bolt is difficult to pass through the second shock absorber due to the existence of tolerances. This ensures that the bolt is easy to install, thereby further improving the installation efficiency of the seat.

[0017] Optionally, the first damping part is provided with a clearance notch located between two adjacent second damping parts, and another second damping part of the flexible elastomer can extend into the clearance notch.

[0018] By adopting the above technical solution, since the first shock absorber is provided with a clearance notch between two adjacent second shock absorbers, and the second shock absorber of another flexible elastomer can extend into the clearance notch, the size of the second shock absorber in the bolt axial direction can be increased to improve the vibration absorption effect of the flexible elastomer, thereby further improving the passenger's riding comfort. On the other hand, the adjustment range of the distance between the two first shock absorbers can be increased, so that the seat fixed shock absorber structure can be used to fix and install various types of seats, avoiding the need to develop different shock absorbers for different seats, thereby increasing the flexibility of the seat fixed shock absorber structure.

[0019] Optionally, the dimension of the body in the radial direction of the bolt is smaller than the dimension of the first shock-absorbing part in the radial direction of the bolt;

[0020] And / or, the dimension of the extension in the axial direction of the bolt is smaller than the dimension of the second damping portion in the axial direction of the bolt.

[0021] By adopting the above technical solution, since the size of the main body in the radial direction of the bolt is smaller than that of the first shock absorber in the radial direction of the bolt, the size of the main body is reduced. This reduces the amount of raw materials required for the production of the bracket, thereby reducing the production cost of the bracket. On the other hand, it reduces the weight of the bracket, thus facilitating the lightweighting of the seat fixing shock absorption structure.

[0022] Since the dimension of the extension in the bolt axial direction is smaller than that of the second shock absorber in the bolt axial direction, the dimension of the extension is reduced. This reduces the amount of raw materials required for the production of the bracket, thereby reducing the manufacturing cost of the bracket. It also reduces the weight of the bracket, thus facilitating the lightweighting of the seat fixing and shock absorption structure.

[0023] Optionally, the first shock-absorbing part is provided with a receiving notch, and the main body is located in the receiving notch;

[0024] And / or, the second shock absorber is provided with a receiving notch, and the extension is located in the receiving notch.

[0025] By adopting the above technical solution, since the first damping part is provided with a receiving notch and the main body is located in the receiving notch, the connection area between the main body and the first damping part is increased, thereby increasing the connection stability between the main body and the first damping part, and thus improving the protective effect of the bracket on the flexible elastomer.

[0026] Because the second damping part is provided with a receiving notch, the extension part is located in the receiving notch, which increases the connection area between the extension part and the second damping part, thereby increasing the connection stability between the extension part and the second damping part, and thus improving the protective effect of the support on the flexible elastomer.

[0027] Optionally, the second shock absorber is provided with a receiving notch, the opening wall of the receiving notch opposite to the first shock absorber protruding in a direction away from the first shock absorber, and the extension is located in the receiving notch and adapted to the receiving notch.

[0028] By adopting the above technical solution, since the accommodating notch and the wall opposite to the first shock absorber protrude in the direction away from the first shock absorber, and the extension is adapted to the accommodating notch, the accommodating notch and the wall opposite to the first shock absorber can cooperate with the end of the extension away from the body to limit the relative rotation of the flexible elastomer and the support, thereby increasing the connection stability between the support and the flexible elastomer, and further increasing the protective effect of the support on the flexible elastomer.

[0029] Optionally, the flexible elastomer is integrally formed on the support;

[0030] And / or, the bracket is made of plastic material.

[0031] By adopting the above technical solution, since the flexible elastomer is integrally molded into the bracket, the connection stability between the flexible elastomer and the bracket is increased, thereby further enhancing the protective effect of the bracket on the flexible elastomer. On the other hand, it avoids the need to assemble the bracket and the flexible elastomer together, thereby improving the production efficiency of the shock absorber.

[0032] Because the bracket is made of plastic, the production cost of the bracket is reduced, thereby reducing the production cost of the seat fixing and shock absorption structure. At the same time, the production difficulty of the bracket is reduced, thereby improving the production efficiency of the bracket. In addition, compared with the bracket made of composite material, the weight of the bracket is reduced, so as to facilitate the lightweight design of the seat fixing and shock absorption structure.

[0033] Optionally, the bolt is a stepped bolt, and the stepped bolt has an anti-rotation part at the step. The seat fixing and shock absorption structure also includes a washer located between the nut and the shock absorber. The washer has a mating part that cooperates with the anti-rotation part in the circumferential direction of the stepped bolt.

[0034] By adopting the above technical solution, before installing the nut, the washer is first installed on the stepped bolt so that the anti-rotation part on the stepped bolt and the mating part on the washer cooperate. The anti-rotation part and the mating part stop in the circumferential direction of the stepped bolt to limit the rotation of the washer with the nut when the nut is installed, so as to avoid the washer rubbing against the flexible elastomer and ensure the service life of the flexible elastomer.

[0035] Meanwhile, if the washer can rotate with the nut, it will exert a torsional force on the flexible elastomer as it rotates with the nut, causing the flexible elastomer to elastically twist in its circumferential direction. When the rotational force on the nut disappears, the flexible elastomer will gradually recover its deformation and exert a reverse force on the nut through the washer, thereby causing the nut to loosen. This will affect the stability of the seat and the effect of isolating the seat from vibration. In this application, by setting an anti-rotation part and a mating part, the situation of the washer rotating with the nut can be avoided, so as to ensure the fixing effect of the seat fixing and shock absorption structure on the seat and the effect of isolating the seat from vibration.

[0036] Optionally, the anti-rotation part is an anti-rotation block provided at the step, and the mating part is an anti-rotation notch provided in the gasket, wherein the anti-rotation block can extend into the anti-rotation notch.

[0037] By adopting the above technical solution, after the washer is installed on the stepped bolt, the anti-rotation block extends into the anti-rotation notch. Then, the anti-rotation block and the wall of the anti-rotation notch can stop the relative rotation of the washer and the bolt in the circumferential direction of the stepped bolt. By setting the anti-rotation part as the anti-rotation block and the mating part as the anti-rotation notch, the manufacturing difficulty of the stepped bolt and washer can be reduced while ensuring the structural strength of the stepped bolt and washer, thereby reducing the manufacturing cost of the stepped bolt and washer.

[0038] This application also discloses a vehicle to improve the efficiency of vehicle assembly and enhance the passenger riding experience.

[0039] A vehicle includes a vehicle body and a seat, wherein the seat is fixed to the vehicle body by a seat fixing and shock absorption structure as described above;

[0040] Alternatively, the vehicle body may be equipped with feet, and the seat may be fixed to the feet by a seat fixing and shock absorption structure as described above.

[0041] By adopting the above technical solution, the seat in this application is fixedly installed on the vehicle body through the aforementioned seat fixing and shock absorption structure, thereby improving the efficiency of seat fixing and installation, thus improving the assembly efficiency of the vehicle. At the same time, it also avoids seat vibration, thereby improving passenger comfort. In addition, it also avoids noise at the connection between the seat and the vehicle body, thereby improving the passenger riding experience.

[0042] Since the seat in this application is fixedly installed on the base of the vehicle body through the aforementioned seat fixing and shock absorption structure, the efficiency of fixing and installing the seat is improved, thereby improving the assembly efficiency of the vehicle. At the same time, seat vibration is avoided, thereby improving passenger comfort. In addition, noise is avoided at the connection between the seat and the base, thus improving the passenger riding experience.

[0043] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0044] 1. The seat fixing and shock absorption structure in this application includes bolts passing through the seat frame and the vehicle body or base, nuts threaded to the bolts, and two shock absorbers. Each shock absorber includes a flexible elastomer sleeved outside the bolt and a bracket disposed on the flexible elastomer. Each flexible elastomer includes a first shock absorber located outside the seat frame and a second shock absorber extending into the seat frame. Each bracket includes a body disposed on the first shock absorber and an extension disposed on the outside of the second shock absorber. The extension extends from the inside of the body in a direction away from the first shock absorber. Both the side of the body away from the first shock absorber and the side of the extension away from the second shock absorber have plastic contact layers, thereby allowing the bracket to contact the seat frame through the plastic contact layers to avoid noise caused by friction between the bracket and the seat frame, thus improving the passenger's riding experience. It also reduces the number of parts required for seat fixing and installation, thereby improving the installation efficiency of the seat.

[0045] 2. The first shock absorber in this application has a ring structure, which can improve the absorption effect of the flexible elastomer on the axial vibration of the bolt, thereby further isolating the vibration transmitted in the axial direction of the bolt and further ensuring the passenger's riding comfort. Multiple second shock absorbers are arranged at intervals along the axial direction of the first shock absorber, and an insertion space for accommodating another flexible elastomer is formed between two adjacent second shock absorbers. This makes the structures of the two shock absorbers completely identical, so that the two shock absorbers can be manufactured from the same mold, thereby reducing the production cost of the shock absorbers and thus reducing the production cost of the seat fixed shock absorber structure. On the other hand, the two shock absorbers can be staggered and cross-fitted, so that the second shock absorber can completely wrap the bolt as much as possible in the circumferential direction of the bolt, thereby ensuring the absorption effect of the second shock absorber on the radial vibration of the bolt, thereby further isolating the vibration transmitted in the radial direction of the bolt and further ensuring the passenger's riding comfort.

[0046] 3. The first shock absorber in this application is provided with a clearance notch between two adjacent second shock absorbers. The second shock absorber of another flexible elastomer can extend into the clearance notch. This increases the size of the second shock absorber in the bolt axial direction to improve the vibration absorption effect of the flexible elastomer, thereby further improving passenger comfort. It also increases the range of adjustment for the distance between the two first shock absorbers, allowing the seat fixing shock absorber structure to be used for fixing various types of seats, avoiding the need to develop different shock absorbers for different seats, thus increasing the flexibility of the seat fixing shock absorber structure.

[0066] Reference Figures 1 to 11 A seat fixing shock absorption structure includes bolts 3 passing through a seat frame 1 and a vehicle body or footrest 2, nuts 4 threaded to the bolts 3, and two shock absorbers 5. Each shock absorber 5 includes a flexible elastomer 51 sleeved outside the bolt 3 and a bracket 52 disposed on the flexible elastomer 51. Each flexible elastomer 51 includes a first shock absorber 511 located outside the seat frame 1 and a second shock absorber 512 extending into the seat frame 1. Each bracket 52 includes a body 521 disposed on the first shock absorber 511 and an extension 522 disposed on the outside of the second shock absorber 512. The extension 522 extends from the inside of the body 521 in a direction away from the first shock absorber 511. The side of the body 521 away from the first shock absorber 511 and the side of the extension 522 away from the second shock absorber 512 both have a plastic contact layer.

[0067] It is understood that the first shock absorber 511 has an inner end face facing the seat frame 1 and an outer end face away from the seat frame 1, and the body 521 is disposed on the inner end face of the first shock absorber 511.

[0068] It should be noted that the outer side of the second shock absorber 512 refers to the side of the second shock absorber 512 away from the bolt 3; the inner side of the body 521 refers to the side of the body 521 close to the bolt 3; the "bolt 3 passing through the seat frame 1 and the vehicle body or the foot 2" mentioned above refers to the bolt 3 passing through the seat frame 1 and the vehicle body for vehicles without foot 2 on the vehicle body, and the bolt 3 passing through the seat frame 1 and the foot 2 for vehicles with foot 2 on the vehicle body.

[0069] When using the seat fixing and shock absorption structure of this application to fix the seat, first install two shock absorbers 5 onto the seat frame 1, so that the second shock absorber parts 512 on the two flexible elastomers 51 extend into the holes of the seat frame 1, and the first shock absorber parts 511 of the two flexible elastomers 51 are respectively located on the upper and lower sides of the seat frame 1, and the two brackets 52 are respectively located at both ends of the hole structure on the seat frame 1. Then move the seat to the desired installation position so that the hole structure on the seat frame 1 matches the hole structure on the vehicle body for installing the seat frame 1. Align the seat with the holes on the base 2 of the vehicle body, and make the first shock absorber 511 at the bottom of the seat frame 1 contact the vehicle body or base 2. Then install the bolt 3 so that the bolt 3 passes through the holes on the seat frame 1 and the holes on the vehicle body or base 2. Finally, install the nut 4 so that the nut 4 is threaded together with the bolt 3, and use the nut 4 to apply pressure to the shock absorber 5, so as to fix the seat to the vehicle body or to the base 2 of the vehicle body.

[0070] When a vehicle with a seat installed on the vehicle body or foot 2 vibrates due to the seat fixing and shock absorption structure described in this application, the vibration of the vehicle body is directly transmitted to the flexible elastomer 51 or transmitted to the flexible elastomer 51 through the foot 2, thereby allowing the flexible elastomer 51 to absorb the vibration and isolate the vibration of the vehicle body from the seat frame 1, thus avoiding the occurrence of seat vibration and improving passenger comfort.

[0071] Since the main body 521 is located on the first shock absorber 511 and the extension 522 is located on the outside of the second shock absorber 512, the extension 522 extends from the inside of the main body 521 in a direction away from the first shock absorber 511. As a result, after the shock absorber 5 is installed on the seat frame 1, the flexible elastomer 51 contacts the corner of the hole in the seat frame 1 through the bracket 52, so as to avoid the corner of the hole in the seat frame 1 from damaging the flexible elastomer 51. This ensures the service life of the flexible elastomer 51 and avoids the connection stability between the seat and the vehicle body or the foot 2 due to the damage of the flexible elastomer 51, thereby ensuring the connection stability between the seat and the vehicle body or the foot 2.

[0072] Furthermore, since the side of the main body 521 facing away from the first shock absorber 511 and the side of the extension 522 facing away from the second shock absorber 512 both have plastic contact layers, the bracket 52 contacts the seat frame 1 through the plastic contact layers, thereby avoiding the situation where the bracket 52 and the seat frame 1 rub against each other and generate noise, thus improving the passenger's riding experience.

[0073] Since the bracket 52 is located on the flexible elastomer 51, when installing the shock absorber 5, only the flexible elastomer 51 needs to be installed so that the bracket 52 is attached to the flexible elastomer 51 and installed to the seat frame 1. This avoids the need to install the flexible elastomer 51 and the bracket 52 separately, thereby reducing the number of parts required for fixing the seat and improving the installation efficiency of the seat.

[0074] This application does not specifically limit the material used to manufacture the flexible elastomer 51. Preferably, the flexible elastomer 51 is made of rubber material to increase its stability while ensuring vibration absorption, thereby extending its service life. In other embodiments, the flexible elastomer 51 may also be made of nylon material or other flexible materials capable of absorbing vibration.

[0075] This application does not specify the installation method of bolt 3, which can be as follows: Figure 9 As shown, a footrest 2 extends downwards from the top of the seat frame 1 and passes through the seat frame 1 and the vehicle body, or is located on the vehicle body; it can also be as follows: Figure 10 The seat frame 1 extends from below the vehicle body or the footrest 2 located on the vehicle body and passes through the vehicle body or the footrest 2 located on the vehicle body.

[0076] This application does not specifically limit the structure of the first damping part 511 and the second damping part 512. Preferably, refer to Figures 2 to 5 The first damping part 511 has a ring structure, and multiple second damping parts 512 are arranged at intervals along the circumference of the first damping part 511. An insertion space 515 for accommodating another flexible elastic body 51 is formed between two adjacent second damping parts 512.

[0077] It is understandable that the first damping part 511 is a ring structure sleeved on the bolt 3, and the second damping part 512 is a strip-shaped rib structure.

[0078] After the two shock absorbers 5 are installed on the seat frame 1, the second shock absorbers 512 on the two flexible elastomers 51 are interlocked and connected, that is, the second shock absorber 512 on one flexible elastomer 51 is inserted into the interlocking space 515 formed between two adjacent second shock absorbers 512 on the other flexible elastomer 51.

[0079] Since the first shock absorber 511 has a ring structure, it can improve the absorption effect of the flexible elastomer 51 on the axial vibration of the bolt 3, so as to further isolate the vibration transmitted in the axial direction of the bolt 3, thereby further ensuring the passenger's riding comfort.

[0080] Furthermore, since multiple second shock absorbers 512 are spaced apart along the circumference of the first shock absorber 511, and an insertion space 515 is formed between two adjacent second shock absorbers 512 to accommodate another flexible elastomer 51, the structures of the two shock absorbers 5 are completely identical, so that the two shock absorbers 5 can be manufactured from the same mold, thereby reducing the production cost of the shock absorbers 5 and thus reducing the production cost of the seat fixed shock absorption structure. On the other hand, the two shock absorbers 5 can be staggered and cross-fitted, so that the second shock absorber 512 can completely wrap the bolt 3 as much as possible in the circumferential direction of the bolt 3, thereby ensuring the vibration absorption effect of the second shock absorber 512 on the radial direction of the bolt 3, further isolating the vibration transmitted in the radial direction of the bolt 3, and further ensuring the passenger's riding comfort.

[0081] Meanwhile, since there may be tolerances in the manufacturing of the shock absorber 5, by arranging multiple second shock absorbers 512 at intervals along the circumference of the first shock absorber 511, the second shock absorber 512 can be more easily deformed in the radial direction of the bolt 3. This avoids the situation where the bolt 3 is difficult to pass through the second shock absorber 512 due to the existence of tolerances, thereby ensuring the effect of easy installation of the bolt 3 and further improving the installation efficiency of the seat.

[0082] This application does not specify the particular arrangement of the second damping section 512; preferably, refer to... Figures 2 to 5 The second damping portion 512 is arranged parallel to the axial direction of the bolt 3 to reduce the manufacturing difficulty of the flexible elastomer. In other embodiments, the second damping portion 512 may also be arranged to extend spirally along the circumference of the bolt 3 to increase the stability of the misaligned insertion of the second damping portions 512 on the two flexible elastomers 51.

[0083] The better one is to refer to Figure 4 and Figure 5 Multiple second damping parts 512 are evenly spaced along the circumference of the first damping part 511, and the insertion space 515 is adapted to the second damping parts 512. This achieves the effect of facilitating the installation of the two damping components 5, and also allows the second damping parts 512 on the two damping components 5 to cooperate with each other and completely wrap around the bolt 3 in the circumference of the bolt 3, so as to ensure the effect of the flexible elastomer 51 in absorbing vibration.

[0084] This application does not specify the number of second damping portions 512 in each flexible elastomer 51. Preferably, refer to Figure 3 and Figure 4Each flexible elastomer 51 has three second damping portions 512 to ensure the stability of the connection between the second damping portions 512 and the first damping portions 511 while reducing the manufacturing difficulty of the flexible elastomer 51. In other embodiments, each flexible elastomer 51 may also have two second damping portions 512 or other numbers of second damping portions 512.

[0085] Furthermore, refer to Figure 3 The first damping part 511 is provided with a clearance notch 513 located between two adjacent second damping parts 512, and the second damping part 512 of another flexible elastomer 51 can extend into the clearance notch 513.

[0086] It is understood that the clearance notch 513 is adapted to the shape of the second damping part 512 so that the second damping part 512 on one of the flexible elastomers 51 can extend into the clearance notch 513 on the other flexible elastomer 51.

[0087] Because the first damping part 511 is provided with a clearance notch 513 between two adjacent second damping parts 512, and the second damping part 512 of another flexible elastomer 51 can extend into the clearance notch 513, the size of the second damping part 512 in the axial direction of the bolt 3 can be increased to improve the vibration absorption effect of the flexible elastomer 51, thereby further improving the passenger's riding comfort. On the other hand, the adjustment range of the distance between the two first damping parts 511 can be increased, so that the seat fixing damping structure can be used to fix and install various types of seats, so as to avoid the need to develop different damping parts 5 for different seats, thereby increasing the flexibility of the seat fixing damping structure.

[0088] The better one is to refer to Figure 6 The main body 521 is a ring structure that extends circumferentially along the bolt 3 to ensure the protective effect of the bracket 52 on the flexible elastomer 51.

[0089] Preferably, the outer contour of the first damping part 511 is frustum-shaped, so as to facilitate the demolding of the flexible elastomer 51.

[0090] In this embodiment, the structure of the extension 522 is not specifically limited. Preferably, the extension 522 is a sheet-like structure, and multiple extensions 522 are provided corresponding to the second damping parts 512, so as to reduce the manufacturing cost of the support 52 while ensuring the protective effect of the support 52 on the flexible elastomer 51. In other embodiments, the extension 522 can also be a columnar structure with a circular, semi-circular or other shapes of cross-section, or even a tubular structure sleeved on the outside of multiple second damping parts 512.

[0091] In other embodiments, the second damping part 512 is an annular structure extending circumferentially along the bolt 3, and multiple first damping parts 511 are spaced apart circumferentially along the bolt 3; or, both the first damping part 511 and the second damping part 512 are annular structures extending circumferentially along the bolt 3.

[0092] This application does not specifically limit the dimensional relationship between the main body 521 and the first shock-absorbing part 511. Preferably, refer to... Figure 2 and Figure 4 The dimension of the main body 521 in the radial direction of the bolt 3 is smaller than the dimension of the first damping part 511 in the radial direction of the bolt 3.

[0093] It is understandable that the main body 521 is coaxially arranged with the first damping part 511, and the diameter of the main body 521 is smaller than the diameter of the first damping part 511.

[0094] Since the size of the main body 521 in the radial direction of the bolt 3 is smaller than that of the first shock absorber 511 in the radial direction of the bolt 3, the size of the main body 521 is reduced. This reduces the amount of raw materials required for the production of the bracket 52, thereby reducing the production cost of the bracket 52. It also reduces the weight of the bracket 52, thus facilitating the lightweighting of the seat fixing shock absorption structure.

[0095] In other embodiments, the size of the body 521 in the radial direction of the bolt 3 may also be equal to the size of the first damping part 511 in the radial direction of the bolt 3, or the size of the body 521 in the radial direction of the bolt 3 may be greater than the size of the first damping part 511 in the radial direction of the bolt 3; that is, the diameter of the body 521 may be equal to the diameter of the first damping part 511 or the diameter of the body 521 may be greater than the diameter of the first damping part 511.

[0096] This application does not specifically limit the dimensional relationship between the extension 522 and the second shock-absorbing part 512. Preferably, refer to... Figure 2 and Figure 4 The dimension of the extension 522 in the axial direction of the bolt 3 is smaller than the dimension of the second damping part 512 in the axial direction of the bolt 3.

[0097] It is understandable that the dimension of the extension 522 in the axial direction of the bolt 3 is the length of the extension 522, and the dimension of the second damping part 512 in the axial direction of the bolt 3 is the length of the second damping part 512. In other words, the above-mentioned "the dimension of the extension 522 in the axial direction of the bolt 3 is smaller than the dimension of the second damping part 512 in the axial direction of the bolt 3" means that the length of the extension 522 is smaller than the length of the second damping part 512.

[0098] Since the dimension of the extension 522 in the axial direction of the bolt 3 is smaller than the dimension of the second shock absorber 512 in the axial direction of the bolt 3, the dimension of the extension 522 is reduced. This reduces the amount of raw materials required for the production of the bracket 52, thereby reducing the production cost of the bracket 52. It also reduces the weight of the bracket 52, thus facilitating the lightweighting of the seat fixing shock absorber structure.

[0099] In other embodiments, the length of the extension 522 may also be equal to the length of the second shock absorber 512.

[0100] In a preferred embodiment, refer to Figure 5 The first shock absorber 511 is provided with a receiving notch 514, and the body 521 is located in the receiving notch 514, thereby increasing the connection area between the body 521 and the first shock absorber 511, so as to increase the connection stability between the body 521 and the first shock absorber 511, and thus improve the protective effect of the bracket 52 on the flexible elastomer 51.

[0101] The better one is to refer to Figure 4 The end face of the main body 521 that is away from the outer end face of the first shock absorber 511 is flush with the inner end face of the first shock absorber 511, so as to further increase the connection area between the main body 521 and the first shock absorber 511, thereby further increasing the connection stability between the main body 521 and the first shock absorber 511. At the same time, it can also increase the contact area between the shock absorber 5 and the seat frame 1, so as to reduce the pressure between the shock absorber 5 and the seat frame 1, thereby extending the service life of the shock absorber 5.

[0102] In a preferred embodiment, refer to Figure 5 The second shock absorber 512 is provided with a receiving notch 516, and the extension 522 is located in the receiving notch 516, thereby increasing the connection area between the extension 522 and the second shock absorber 512, so as to increase the connection stability between the extension 522 and the second shock absorber 512, and thus improve the protective effect of the bracket 52 on the flexible elastomer 51.

[0103] The better one is to refer to Figure 4 The second shock absorber 512 has an inner side that contacts the bolt 3 and an outer side that is away from the bolt 3. The extension 522 is flush with the outer side of the second shock absorber 512, so that the second shock absorber 512 can contact the inner wall of the hole structure on the seat frame 1, thereby increasing the stability of the shock absorber 5 and increasing the vibration absorption effect of the flexible elastomer 51.

[0104] In a preferred embodiment, refer to Figure 4 and Figure 5The second damping part 512 is provided with a receiving notch 516. The opening wall of the receiving notch 516 opposite to the first damping part 511 protrudes in a direction away from the first damping part 511. The extension part 522 is located in the receiving notch 516 and is adapted to the receiving notch 516.

[0105] Since the receiving notch 516 protrudes in the direction away from the first shock absorber 511, and the extension 522 is adapted to the receiving notch 516, the receiving notch 516 and the end of the extension 522 away from the body 521 can cooperate to limit the relative rotation of the flexible elastomer 51 and the bracket 52, thereby increasing the connection stability between the bracket 52 and the flexible elastomer 51, and further increasing the protective effect of the bracket 52 on the flexible elastomer 51.

[0106] This application does not specifically limit the number of points on the opening wall opposite to the first damping part 511 in the direction away from the first damping part 511. Preferably, the opening wall opposite to the first damping part 511 in the accommodating notch 516 has one point protruding in the direction away from the first damping part 511, so as to reduce the manufacturing difficulty of the support 52 and the flexible elastomer 51 while ensuring the relative rotation limiting effect of the support 52 and the flexible elastomer 51. In other embodiments, the opening wall opposite to the first damping part 511 in the accommodating notch 516 may also have multiple points protruding in the direction away from the first damping part 511.

[0107] This application does not specifically limit the connection method between the flexible elastomer 51 and the bracket 52. Preferably, the flexible elastomer 51 is integrally formed into the bracket 52, which on the one hand increases the connection stability between the flexible elastomer 51 and the bracket 52, thereby further increasing the protective effect of the bracket 52 on the flexible elastomer 51. On the other hand, it avoids the need to assemble the bracket 52 and the flexible elastomer 51 together, thereby improving the production efficiency of the shock absorber 5.

[0108] This application does not specify the method of integrally molding the flexible elastomer into the bracket 52. It can be that the two are molded using a two-color injection molding process; it can also be that the bracket 52 is produced first, and then the bracket 52 is placed into the mold for molding the flexible elastomer 51, so that the flexible elastomer 51 is molded into the bracket 52.

[0109] In other embodiments, the flexible elastomer 51 can also be fixedly connected to the bracket 52 by adhesive or snap-fit.

[0110] This application does not specifically limit the material of the bracket 52. Preferably, the bracket 52 is made of plastic material. That is, the part of the body 521 of the bracket 52 facing away from the first shock absorber 511 and the part of the extension 522 of the bracket 52 facing away from the second shock absorber 512 constitute the plastic contact layer.

[0111] Because the bracket 52 is made of plastic material, the production cost of the bracket 52 is reduced, thereby reducing the production cost of the seat fixing and shock absorption structure. At the same time, the production difficulty of the bracket 52 is reduced, thereby improving the production efficiency of the bracket 52. In addition, compared with the solution of the bracket 52 being made of composite material, the weight of the bracket 52 is reduced, thereby facilitating the lightweight design of the seat fixing and shock absorption structure.

[0112] In other embodiments, the bracket 52 may also be made of a composite material of plastic and steel. That is, the bracket 52 includes an inner layer made of steel and a plastic contact layer made of plastic disposed outside the inner layer. After the plastic contact layer is completely worn away, the inner layer made of steel can also protect the flexible elastomer 51 to avoid the situation where the seat fixation stability is affected due to the wear of the flexible elastomer 51, thereby ensuring the stability of the seat.

[0113] In a preferred embodiment, refer to Figure 7 and Figure 8 Bolt 3 is a stepped bolt, and an anti-rotation part 31 is provided at the step of the stepped bolt. The seat fixing shock absorption structure also includes a washer 6 located between the nut 4 and the shock absorber 5. The washer 6 is provided with a mating part 61 that stops and cooperates with the anti-rotation part 31 in the circumferential direction of the stepped bolt.

[0114] Before installing the nut 4, the washer 6 is first installed on the stepped bolt so that the anti-rotation part 31 on the stepped bolt engages with the mating part 61 on the washer 6. The anti-rotation part 31 and the mating part 61 stop the rotation of the washer 6 with the nut 4 during installation by using the anti-rotation part 31 and the mating part 61 in the circumferential direction of the stepped bolt. This prevents the washer 6 from rubbing against the flexible elastomer 51 and ensures the service life of the flexible elastomer 51.

[0115] Meanwhile, if the washer 6 can rotate with the nut 4, it will cause the flexible elastomer 51 to be subjected to a torsional force when it rotates with the nut 4, so that the flexible elastomer 51 will be elastically torn in its own circumferential direction. When the rotational force on the nut 4 disappears, the flexible elastomer 51 will gradually recover its deformation and exert a reverse force on the nut 4 through the washer 6, thereby causing the nut 4 to loosen, which will affect the fixing stability of the seat and the effect of isolating the seat from vibration. In this application, by setting the anti-rotation part 31 and the mating part 61, the situation of the washer 6 rotating with the nut 4 can be avoided, so as to ensure the fixing effect of the seat fixing and shock absorption structure on the seat and the effect of isolating the seat from vibration.

[0116] This application does not specifically limit the structure of the anti-rotation part 31 and the mating part 61. Preferably, refer to... Figure 7 and Figure 8 The anti-rotation part 31 is an anti-rotation block provided at the step, and the mating part 61 is an anti-rotation notch provided at the gasket 6, and the anti-rotation block can extend into the anti-rotation notch.

[0117] It is understandable that the gasket 6 has a central hole, and the anti-rotation notch is located on the wall of the central hole.

[0118] After the washer 6 is installed on the stepped bolt, the anti-rotation block extends into the anti-rotation notch. Then, the anti-rotation block and the wall of the anti-rotation notch can stop the relative rotation of the washer 6 and the bolt 3 by using the anti-rotation block and the wall of the anti-rotation notch to stop in the circumferential direction of the stepped bolt. By setting the anti-rotation part 31 as the anti-rotation block and the mating part 61 as the anti-rotation notch, the manufacturing difficulty of the stepped bolt and the washer 6 can be reduced while ensuring the structural strength of the stepped bolt and the washer 6, so as to reduce the manufacturing cost of the stepped bolt and the washer 6.

[0119] In other embodiments, the mating part 61 may also be a block structure provided on the gasket 6, and the anti-rotation part 31 may be a notch that can accommodate the block structure; or, the mating part 61 may be a columnar structure provided on the gasket 6, and the anti-rotation part 31 may be a hole structure provided on the step surface of the stepped bolt. After the gasket 6 is installed on the stepped bolt, the columnar structure extends into the hole structure, so as to restrict the relative rotation of the gasket 6 and the stepped bolt by utilizing the cooperation between the columnar structure and the hole structure.

[0120] This application does not specifically limit the number of anti-rotation parts 31 and mating parts 61. Preferably, multiple anti-rotation parts 31 are evenly spaced along the circumference of the stepped bolt, and multiple mating parts 61 are evenly spaced along the circumference of the washer 6. Each mating part 61 corresponds to one anti-rotation part 31. This increases the number of stopping points between the stepped bolt and the washer 6, further preventing the washer 6 from rotating with the nut 4. It also facilitates the mating of the anti-rotation parts 31 and 61, reducing the difficulty of installing the washer 6 and improving the efficiency of seat installation. In other embodiments, only one anti-rotation part 31 and one mating part 61 may be provided; even for schemes where the anti-rotation part 31 is a anti-rotation block and the mating part 61 is a anti-rotation notch, only one anti-rotation part 31 may be provided, while multiple mating parts 61 may be provided.

[0121] Reference Figures 9 to 11 This application also discloses a vehicle, which includes a vehicle body and a seat, wherein the seat is fixed to the vehicle body by the aforementioned seat fixing and shock absorption structure; or, the vehicle body is provided with a foot 2, and the seat is fixed to the foot 2 by the aforementioned seat fixing and shock absorption structure.

[0122] It is understood that the seat has a seat frame 1. The above-mentioned "the seat is fixed to the vehicle body by the above-mentioned seat fixing and shock absorption structure" means that the seat frame 1 of the seat is fixed to the vehicle body by the above-mentioned seat fixing and shock absorption structure. The "the seat is fixed to the ground foot 2 by the above-mentioned seat fixing and shock absorption structure" means that the seat frame 1 of the seat is fixed to the ground foot 2 by the above-mentioned seat fixing and shock absorption structure.

[0123] Since the seat in this application is fixedly installed on the vehicle body through the aforementioned seat fixing and shock absorption structure, or fixedly installed on the foot 2 provided on the vehicle body through the aforementioned seat fixing and shock absorption structure, the efficiency of fixing and installing the seat is improved, thereby improving the assembly efficiency of the vehicle. At the same time, seat vibration is avoided, thereby improving passenger comfort. In addition, noise is avoided at the connection between the seat and the vehicle body, thereby improving the passenger riding experience.

[0124] In a preferred embodiment, the seat has a backrest with a resonator inside, which can absorb vibrations not absorbed by the damping element 5, thereby further improving passenger comfort.
