Abstract
Description
Technical Field
[0001] This utility model relates to the field of shock absorber technology, and in particular to a spherical shock absorber. Background Technology
[0002] The technological development of shock absorbers (also known as dampers) involves various design principles, materials science, and control methods. Shock absorbers used in automotive instruments are primarily used to isolate engine vibration, road bumps, or vibrations during equipment operation, protecting the precision electronic components and display assemblies inside the instrument. Their design and structure must balance damping performance, durability, and space constraints. Currently, common types of rubber shock absorbers on the market mainly include: cylindrical rubber shock absorbers, with a cylindrical rubber block as the main body, possibly with embedded metal sleeves or bolts; the rubber material is bonded to the metal parts through a vulcanization process to form an integral structure; conical rubber shock absorbers, with a conical or tower-shaped rubber body, wide at the bottom and narrow at the top, achieving multi-directional vibration absorption through shape optimization, often paired with a metal base or top plate to enhance installation stability; and composite rubber shock absorbers, consisting of multiple layers of rubber and metal sheets stacked alternately to form a composite damping effect, where the metal sheets limit the deformation range of the rubber and improve fatigue resistance.
[0003] To ensure damping performance, existing rubber shock absorbers typically incorporate sufficient buffer structures in the compression direction, resulting in a larger overall height and volume. However, these shock absorbers require a significant amount of installation space in practical applications, thus limiting their installation scenarios and making them difficult to use in confined spaces. Utility Model Content
[0004] Therefore, it is necessary to provide a spherical shock absorber to address the technical problem of the large volume of existing rubber shock absorbers under the equivalent damping capacity.
[0005] A spherical shock absorber includes a main body, connectors, and reinforcing members. The connectors are located at both ends of the main body, and the reinforcing members are located inside the main body.
[0006] The main body is a hollow, spherical structure with connecting end faces at its top and bottom ends along its central axis. Connecting parts are respectively located at the connecting end faces at the top and bottom ends of the main body. The reinforcing parts are designed as ring-shaped structures, and are fitted into the inner wall surface of the main body, with the top and bottom ends of the reinforcing parts corresponding to the inner sides of the two connecting end faces. Subsequently, the connecting parts are fitted into the corresponding connecting end faces and connected to the corresponding ends of the reinforcing parts.
[0007] In one embodiment, the main body is further provided with a reinforcing structure, which is disposed on the outer surface of the main body.
[0008] In one embodiment, the aforementioned reinforcing structure includes a first reinforcing part, a second reinforcing part, and a third reinforcing part; the first reinforcing part is disposed on the outer surface of the top of the main body and the outer surface of the bottom of the main body; the second reinforcing part extends along the outer surface of the side wall of the main body from the connecting end face at one end to the connecting end face at the other end; the third reinforcing part is disposed on the outer surface of the side wall between the two connecting end faces of the main body, and the third reinforcing part is arranged to surround the main body in a ring-shaped reinforcing structure.
[0009] In one embodiment, the second reinforcing part is configured as a plurality of arc-shaped reinforcing structures extending along the central axis of the main body; the third reinforcing part intersects the second reinforcing part perpendicularly, thereby forming a latitude and longitude network reinforcing structure based on the main body.
[0010] In one embodiment, the main body is provided with a plurality of through holes, which are disposed through the side wall of the main body.
[0011] In one embodiment, the aforementioned through holes are provided as two, and the two through holes are respectively provided on the opposite two side walls of the main body.
[0012] In one embodiment, the above-mentioned reinforcing structure is provided with a plurality of fourth reinforcing parts corresponding to a plurality of through holes, and the fourth reinforcing parts are arranged around the edge of the corresponding through holes to form an annular reinforcing structure.
[0013] In one embodiment, the connecting end face is provided with a mounting hole, and the connector is fitted into the mounting hole accordingly.
[0014] In one embodiment, the mounting hole is provided with a first fastening part, which is disposed on the inner wall of the mounting hole; correspondingly, a second fastening part is provided at the edge of the connector, which can be engaged with the first fastening part; when the connector is fitted into the mounting hole, the first fastening part engages with the second fastening part for connection.
[0015] In one embodiment, the connector is further provided with a mating part, which extends inward by a predetermined distance from one side surface of the connector toward the interior of the main body; correspondingly, the reinforcement is provided with a mating hole, the hole wall of which mates with the side surface of the mating part, and when the connector is installed in place, the mating part mates with the mating hole.
[0016] In one embodiment, the connector is further provided with a connecting hole, which extends through the outer surface of the connector to the inner surface of the connector, based on the main body.
[0017] The aforementioned spherical shock absorber, through its reinforcing components, strengthens the structural strength of the main body from within, thereby significantly improving its shock absorption capacity while controlling the overall volume of the main body. The connecting components also define the relative position between the reinforcing components and the main body, ensuring the stability of the connection within the main body. When the spherical shock absorber is correctly installed at its intended application location, it can be compressed along its central axis to absorb impact forces. During this process, the reinforcing components support the connecting components at both ends and the side walls of the connected main body, thus strengthening the overall impact resistance of the spherical shock absorber and effectively improving its shock absorption performance without increasing the volume of the main body. Based on equivalent shock absorption performance, compared to traditional rubber shock absorbers, this spherical shock absorber effectively reduces its volume while maintaining shock absorption capacity, making it more suitable for confined application scenarios and providing excellent shock absorption performance.

[0027] Please see Figures 1 to 3This utility model discloses a spherical shock absorber 1, which includes a main body 10, a connector 20, and a reinforcing member 30. The connector 20 is disposed at both ends of the main body 10, and the reinforcing member 30 is disposed inside the main body 10. Thus, the main body 10 can be stably connected to the externally preset connection points through the connector 20, while the reinforcing member 30 can strengthen the structural strength of the main body 10 from the inside. In this way, the shock absorption capacity of the main body 10 can be greatly improved while controlling the overall volume of the main body 10. Specifically, the main body 10 is configured as a hollow, spherical structure, with connecting end faces 11 at both the top and bottom ends along its central axis; connecting members 20 are respectively disposed at the connecting end faces 11 at both the top and bottom ends of the main body 10; the reinforcing member 30 is configured as a ring-shaped structure, based on which the reinforcing member 30 is fitted into the inner wall surface of the main body 10, and the top and bottom ends of the reinforcing member 30 respectively correspond to the inner sides of the two connecting end faces 11; then, the connecting member 20 is fitted into the corresponding connecting end face 11 and connected to the corresponding end of the reinforcing member 30. Based on the above structure, the connector 20 can also limit the relative position between the reinforcement 30 and the main body 10, thereby ensuring the connection stability of the reinforcement 30 inside the main body 10. When the spherical shock absorber 1 is correctly installed at the actual application point, the spherical shock absorber 1 can be compressed along the central axis to absorb the impact force. During this process, the reinforcement 30 supports the connectors 20 at both the top and bottom ends, and the reinforcement 30 supports the side walls of the main body 10 to which it is connected, thereby strengthening the overall impact resistance of the spherical shock absorber 1. Thus, without increasing the volume of the main body 10, the shock absorption performance of the spherical shock absorber 1 is effectively improved. Based on the equivalent shock absorption performance, compared with traditional rubber shock absorbers, the spherical shock absorber 1 of this utility model can effectively reduce the volume while ensuring the shock absorption capacity, making it more suitable for narrow application scenarios and providing excellent shock absorption performance.
[0028] Furthermore, the main body 10 is also provided with a reinforcing structure, which is provided on the outer surface of the main body 10 to further enhance the structural strength of the main body 10.
[0029] Furthermore, in one embodiment, the reinforcing structure includes a first reinforcing part 12, a second reinforcing part 13, and a third reinforcing part 14; the first reinforcing part 12 is disposed on the outer surface of the top of the main body 10 and the outer surface of the bottom of the main body 10 to structurally reinforce the top and bottom of the main body 10; the second reinforcing part 13 extends along the outer surface of the sidewall of the main body 10 from one end connection face 11 to the other end connection face 11; the third reinforcing part 14 is disposed on the outer surface of the sidewall between the two connection face 11s of the main body 10, and the third reinforcing part 14 is arranged circumferentially around the main body 10 to form a ring-shaped reinforcing structure. Based on the above configuration, in another embodiment, the second reinforcing part 13 is configured as several arc-shaped reinforcing structures extending along the central axis of the main body 10; the third reinforcing part 14 intersects the second reinforcing part 13 perpendicularly, thereby forming a latitude and longitude network reinforcing structure based on the main body 10 to sufficiently reinforce the sidewall of the main body 10.
[0030] Furthermore, in one embodiment, the main body 10 is provided with a plurality of through holes a, which are disposed through the side wall of the main body 10, thereby enabling the interior of the main body 10 to communicate with the exterior, so as to achieve internal and external air pressure balance and thus avoid the generation of internal and external pressure difference when the main body 10 is compressed, which would affect the damping operation of the spherical shock absorber 1. In another embodiment, there are two through holes a, and the two through holes a are respectively disposed on opposite side walls of the main body 10.
[0031] Furthermore, the reinforcing structure is provided with several fourth reinforcing parts 15 corresponding to several through holes a. The fourth reinforcing parts 15 are arranged around the edge of the corresponding through hole a to form an annular reinforcing structure, thereby reinforcing the hole wall.
[0032] Furthermore, the connecting end face 11 is provided with a mounting hole b, and the connector 20 is correspondingly fitted into the mounting hole b, thereby enabling the connector 20 to be stably connected to the main body 10. Specifically, in one embodiment, the mounting hole b is provided with a first fastening part 111, which is located on the inner wall of the mounting hole b; correspondingly, the edge of the connector 20 is provided with a second fastening part 21, which can cooperate with the first fastening part 111; when the connector 20 is fitted into the mounting hole b, the first fastening part 111 and the second fastening part 21 cooperate to connect, thereby enhancing the connection stability of the connector 20 to the main body 10.
[0033] Furthermore, the connector 20 is also provided with a mating part 22, which extends inward by a predetermined distance from one side surface of the connector 20 toward the interior of the main body 10; correspondingly, the reinforcement 30 is provided with a mating hole c, the wall of the mating hole c is mated with the side surface of the mating part 22, when the connector 20 is installed in place, the mating part 22 is mated and connected to the mating hole c, so that the connector 20 can limit the installation position of the reinforcement 30 inside the main body 10.
[0034] Furthermore, the connector 20 is also provided with a connection hole d, which extends from the outer surface of the connector 20 to the inner surface of the connector 20 based on the main body 10, for connection between preset application surfaces.
[0035] In summary, the spherical shock absorber disclosed in this invention strengthens the structural strength of the main body from within through the reinforcing member, thereby significantly improving the shock absorption capacity of the main body while controlling its overall volume. The connecting member also defines the relative position between the reinforcing member and the main body, ensuring the connection stability of the reinforcing member within the main body. When the spherical shock absorber is correctly installed at its intended application location, it can be compressed along its central axis to absorb impact forces. During this process, the reinforcing member supports the connecting members at both ends and the side walls of the connected main body, thereby enhancing the overall impact resistance of the spherical shock absorber and effectively improving its shock absorption performance without increasing the volume of the main body. Based on equivalent shock absorption performance, compared to traditional rubber shock absorbers, the spherical shock absorber of this invention effectively reduces its volume while maintaining shock absorption capacity, making it more suitable for confined application scenarios and providing excellent shock absorption performance.
[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
