Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and in particular to a spring 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] Existing shock absorbers mainly consist of a rubber body and metal inserts. The rubber body is usually made of one of the following: natural rubber (NR), silicone rubber (VMQ), chloroprene rubber (CR), or nitrile rubber (NBR). The metal inserts are mainly bolts, nuts, or metal sleeves embedded in the rubber body for connection between the shock absorbers. However, the support of such shock absorbers mainly comes from the mechanical strength of the rubber body itself, which limits the application scenarios of these shock absorbers. In high-impact application scenarios, insufficient support is prone to occur, thus limiting their shock absorption capacity. Utility Model Content

[0004] Therefore, it is necessary to provide a spring shock absorber to address the technical problem of insufficient support in existing shock absorbers.

[0005] A spring shock absorber includes a base, a main body, a first connecting member, a second connecting member, and an elastic member. The main body is disposed on the top side of the base, and the bottom end of the main body is connected to the top side surface of the base. The first connecting member is disposed at the geometric center of the base, and extends from the bottom side surface of the base to the top side of the base and is connected to the bottom end of the main body. The second connecting member is disposed at the geometric center of the top end of the main body, and extends from the end face of the top end of the main body into the interior of the main body, and the second connecting member is correspondingly disposed to the first connecting member. The elastic member is movably disposed inside the main body, and its two ends along its energy absorption direction are respectively connected to the first connecting member and the second connecting member.

[0006] In one embodiment, the aforementioned body is made of an elastic material.

[0007] In one embodiment, the main body is sealed to the base, the first connector and the second connector respectively, and based on this, the interior of the main body can be filled with damping oil.

[0008] In one embodiment, the aforementioned body is made of rubber.

[0009] In one embodiment, the elastic element is configured as a spring, and its two ends are respectively connected to the first connector and the second connector.

[0010] In one embodiment, the main body is provided with a first connecting end, which is located at the bottom end of the main body.

[0011] In one embodiment, the aforementioned base is provided with a connecting portion, which corresponds to and engages with the first connecting end.

[0012] In one embodiment, the first connecting end is configured as a columnar groove, and the connecting part is configured as a hollow cylindrical boss corresponding to the first connecting end, so that the connecting part can be fitted into the first connecting end. At this time, the first connecting member can penetrate through the inside of the connecting part and extend to the first connecting end.

[0013] In one embodiment, the first connecting end and the connecting part are subjected to an interference fit.

[0014] In one embodiment, the main body is further provided with a second connecting end and a receiving cavity. The second connecting end is located at the top of the main body; the receiving cavity is located inside the main body, and its two ends are respectively connected to the first connecting end and the second connecting end.

[0015] In one embodiment, the second connector and the second connecting end are correspondingly engaged, thereby enabling the second connector to be sealed to the main body.

[0016] In one embodiment, the elastic member is disposed inside the receiving cavity, and the two ends of the elastic member respectively abut against the first connector and the second connector.

[0017] In one embodiment, the first connector is provided with a connecting groove, a mating part, and a limiting part. Based on the main body, the connecting groove is provided at one external end of the first connector, the limiting part is provided at one internal end of the first connector, and the mating part is provided on the side surface of the first connector. Thus, the first connector is mated with the inner surface of the connecting part through the mating part, the limiting part is mated with the corresponding end of the elastic member, and the connecting groove is used to connect with an external application point.

[0018] In one embodiment, the aforementioned mating portion is configured as an annular groove circumferentially arranged along the side surface of the first connector. Correspondingly, the inner wall surface of the connector is provided with a first annular insert. When the first connector is installed into the connector, the first annular insert is embedded into the mating portion.

[0019] In one embodiment, the second connector described above has the same structure as the first connector and is mirror-installed into the second connector end.

[0020] In one embodiment, the second connecting end is configured as a columnar groove, and a second annular insert is provided on the inner wall surface of the second connecting end.

[0021] In one embodiment, a third annular insert is provided at the bottom end of the aforementioned main body.

[0022] In one embodiment, the aforementioned third annular insert is disposed circumferentially at the edge along the bottom end face of the main body.

[0023] In one embodiment, the top side surface of the aforementioned seat is provided with an annular groove, and when the bottom end of the main body is connected to the seat, the third annular insert is embedded in the annular groove.

[0024] The aforementioned spring shock absorber significantly enhances its damping capacity through the synergistic effect of the buffering performance between the main body and the elastic element. Specifically, the spring shock absorber can be connected to preset connection points via first and second connecting parts at its top and bottom ends. For example, when the spring shock absorber is applied to a vehicle hard drive, the first connecting part connects to the hard drive, and the second connecting part connects to the corresponding mounting point of the hard drive, thereby achieving a buffered connection between the hard drive and the mounting point. The main body, combined with the elastic element, supports and supports the hard drive. When vibration occurs during vehicle operation, the main body and the elastic element deform to absorb energy, thereby absorbing the impact force and achieving a vibration filtering effect. Compared to traditional rubber shock absorbers, the spring shock absorber of this invention, while ensuring vibration filtering performance, has stronger support capacity and is more suitable for high-vibration intensity applications, such as aerospace, aviation, marine, vehicles, and other power machinery. At the same time, by adjusting the buffering performance brought by the material properties of the elastic element and the main body, the support capacity and energy absorption capacity of the spring shock absorber can be further balanced, allowing for flexible matching according to actual needs.

[0035] Please see Figures 1 to 4This utility model discloses a spring shock absorber 1, which includes a base 10, a main body 20, a first connecting member 30, a second connecting member 40, and an elastic member 50. The main body 20 is disposed on the top side of the base 10, and the bottom end of the main body 20 is connected to the top side surface of the base 10. The first connecting member 30 is disposed at the geometric center of the base 10, and extends from the bottom side surface of the base 10 to the top side of the base 10 and is connected to the bottom end of the main body 20. The second connecting member 40 is disposed at the geometric center of the top end of the main body 20, and extends from the end face of the top end of the main body 20 into the interior of the main body 20, and the second connecting member 40 is correspondingly disposed with the first connecting member 30. The elastic member 50 is movably disposed inside the main body 20, and the two ends of the elastic member 50 along its energy absorption direction are respectively connected to the first connecting member 30 and the second connecting member 40. Based on the above configuration, specifically, the main body 20 is made of elastic material; the main body 20 is sealed and connected to the seat 10, the first connecting member 30, and the second connecting member 40 respectively. Therefore, damping oil can be filled inside the main body 20 to further enhance the shock absorption performance of the spring shock absorber 1. In practical applications, the spring shock absorber 1 of this invention can greatly improve its shock absorption capacity based on the synergistic effect of the buffering performance between the main body 20 and the elastic member 50. Specifically, the spring shock absorber 1 can be connected to preset connection points through the first connecting member 30 and the second connecting member 40 at its top and bottom ends, respectively. For example, when the spring shock absorber 1 is applied to a vehicle hard drive, the first connecting member 30 is connected to the hard drive, and the second connecting member 40 is connected to the corresponding mounting point of the hard drive, thereby achieving a buffered connection between the hard drive and the mounting point. The main body 20, combined with the elastic member 50, can support and carry the hard drive. When vibration occurs during vehicle operation, the main body 20, together with the elastic element 50, deforms to absorb energy, thereby absorbing the impact force and achieving a vibration filtering effect. Compared with traditional rubber shock absorbers, the spring shock absorber 1 of this utility model has stronger support capacity while ensuring vibration filtering performance, and is more suitable for high vibration intensity application scenarios, such as aerospace, aviation, marine, vehicles and other power machinery. At the same time, by adjusting the buffering performance brought by the material properties of the elastic element 50 and the main body 20, the support capacity and energy absorption capacity of the spring shock absorber 1 can be further balanced, so as to flexibly match according to actual needs.

[0036] Furthermore, in one embodiment, the main body 20 is made of rubber; in another embodiment, the elastic element 50 is configured as a spring, with its two ends respectively connected to the first connecting member 30 and the second connecting member 40. This ensures the elastic deformation capability of the elastic shock absorber within a certain impact limit.

[0037] Furthermore, the main body 20 is provided with a first connecting end 21, which is located at the bottom end of the main body 20. Correspondingly, the seat 10 is provided with a connecting part 11, which corresponds to and engages with the first connecting end 21, thereby enabling a sealed connection between the seat 10 and the main body 20. In one embodiment, the first connecting end 21 is configured as a columnar groove, and the connecting part 11 is configured as a hollow cylindrical boss corresponding to the first connecting end 21, so that the connecting part 11 can be fitted into the first connecting end 21. In this case, the first connecting member 30 can penetrate through the interior of the connecting part 11 and extend to the first connecting end 21. In another embodiment, the first connecting end 21 and the connecting part 11 are press-fitted, thereby enhancing the sealing between the main body 20 and the seat 10.

[0038] Furthermore, the main body 20 is also provided with a second connecting end 22 and a receiving cavity 23. The second connecting end 22 is located at the top of the main body 20; the receiving cavity 23 is located inside the main body 20, and its two ends are respectively connected to the first connecting end 21 and the second connecting end 22. Based on the above configuration, specifically, the second connecting member 40 and the second connecting end 22 are correspondingly engaged, thereby making the second connecting member 40 and the main body 20 form a sealed connection; the elastic member 50 is located inside the receiving cavity 23, and its two ends are respectively engaged and abut against the first connecting member 30 and the second connecting member 40. When the spring shock absorber 1 receives a vibration impact, the first connecting member 30 and the second connecting member 40 are compressed towards each other, thereby causing the main body 20 and the elastic member 50 to compress and absorb energy, thereby realizing the vibration filtering capability of the spring shock absorber 1.

[0039] Furthermore, in one embodiment, the first connector 30 is provided with a connecting groove a, a mating part b, and a limiting part c. Based on the main body 20, the connecting groove a is located at one external end of the first connector 30, the limiting part c is located at one internal end of the first connector 30, and the mating part b is located on the side surface of the first connector 30. Thus, the first connector 30 mates with the inner surface of the connecting part 11 via the mating part b, and the limiting part c mates with the corresponding end of the elastic member 50. The connecting groove a is used for mating and connecting with an external application point. The mating part b enables a stable connection between the first connector 30 and the connecting part 11, and the limiting part c effectively limits the relative position between the elastic member 50 and the receiving cavity 23, improving the installation stability of the elastic member 50. Furthermore, in another embodiment, the mating part b is configured as an annular groove circumferentially arranged along the side surface of the first connector 30. Correspondingly, the inner wall surface of the connecting part 11 is provided with a first annular insert 111. When the first connector 30 is installed to the connecting part 11, the first annular insert 111 is embedded into the mating part b to further improve the connection stability between the first connector 30 and the connecting part 11. At the same time, the interference fit can further enhance the connection tightness between the first connector 30 and the seat 10.

[0040] Furthermore, in one embodiment, the second connector 40 has the same structure as the first connector 30 and is mirror-installed into the second connecting end 22. Correspondingly, the second connecting end 22 is configured as a columnar groove, and a second annular insert 221 is provided on the inner wall surface of the second connecting end 22. When the second connector 40 is installed into the second connecting end 22, the second annular insert 221 is embedded into the mating portion b of the second connector 40, thereby further improving the connection stability between the second connector 40 and the second connecting end 22. Simultaneously, the interference fit further strengthens the connection tightness between the second connector 40 and the main body 20, thus ensuring the sealing of the receiving cavity 23. In addition, the limiting portion c of the second connector 40, together with the limiting portion c of the first connector 30, respectively mates with both ends of the elastic member 50 to ensure the stability of the elastic member 50 within the receiving cavity 23.

[0041] Furthermore, a third annular insert 24 is provided at the bottom end of the main body 20. Specifically, the third annular insert 24 is disposed at the edge along the circumference of the bottom end face of the main body 20. Correspondingly, an annular groove 12 is provided on the top side surface of the seat 10. When the bottom end of the main body 20 is connected to the seat 10, the third annular insert 24 is embedded in the annular groove 12, thereby improving the connection stability between the main body 20 and the seat 10. At the same time, the interference fit can further strengthen the connection tightness between the main body 20 and the seat 10, thereby ensuring the sealing of the cavity 23 and preventing leakage.

[0042] In summary, the spring shock absorber disclosed in this utility model can greatly improve the shock absorption capacity of the spring shock absorber based on the synergistic effect of the buffering performance between the main body and the elastic element. Specifically, the spring shock absorber can be connected to preset connection points through the first and second connecting parts at its top and bottom ends, respectively. For example, when the spring shock absorber is applied to a vehicle hard drive, the first connecting part is connected to the hard drive, and the second connecting part is connected to the corresponding mounting point of the hard drive, thereby realizing a buffered connection between the hard drive and the mounting point. The main body, combined with the elastic element, can support and support the hard drive. When vibration occurs during vehicle operation, the main body and the elastic element deform and absorb energy to absorb the impact force, thereby achieving a vibration filtering effect. Compared with traditional rubber shock absorbers, the spring shock absorber of this utility model has stronger support capacity while ensuring vibration filtering performance, and is more suitable for high vibration intensity application scenarios, such as aerospace, aviation, marine, vehicles and other power machinery. At the same time, by adjusting the buffering performance brought by the material properties of the elastic element and the main body, the support capacity and energy absorption capacity of the spring shock absorber can be further balanced, so as to flexibly match according to actual needs.

[0043] 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.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. 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.
