Description

Technical Field

[0001] This utility model relates to the field of shock absorption technology for new energy vehicles, and in particular to a hydraulic shock absorber for engines. Background Technology

[0002] Hydraulic damping pads (usually referring to hydraulic shock absorbers) work by using the damping force generated by the flow of liquid to dissipate vibration energy. When the piston moves, the oil is forced to flow through the throttle orifice or valve system, generating flow resistance, thereby forming a damping force to achieve the vibration reduction effect.

[0003] Hydraulic damping pads, when used in new energy vehicles, can improve driving comfort and stability. Currently, engine hydraulic damping pads on the market are generally divided into two types: circular and cylindrical. These two types are suitable for different scenarios and have different installation methods.

[0004] A hydraulic shock absorber for engines, patent number CN202320208197.2, includes an outer pad, with telescopic rods fixedly installed at each of the four corners of the outer pads. An annular hydraulic bag is fixedly installed between the outer pads, and a through hole is formed at the center of each outer pad. An inner pad is installed inside the through hole, and a barrel-shaped hydraulic bag is installed between the inner pads. This design, with its modular outer and inner pad structure, allows for assembly and disassembly, improving both the shock absorption effect and the applicability of the device. However, in practical use, some drawbacks exist. For example, while the outer and inner pads allow for disassembly and assembly, each requires a separate hydraulic bag, which is wasteful of resources. Therefore, this application proposes a hydraulic shock absorber for engines to address these issues. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides an engine hydraulic shock absorber.

[0006] The technical solution adopted by this utility model is as follows: it includes an outer pad, the inner part of which is hollow, and movable rings are movably installed near the top and bottom of the inner cavity of the outer pad. A hydraulic bag is installed between the two movable rings. The hydraulic bag is ring-shaped and has a hydraulic cavity inside. A circular block is movably installed through the two movable rings. A positioning component is provided on the circular block, and a fixing plate is installed on the side of the two circular blocks that are far apart. The fixing plate has multiple fixing holes.

[0007] Preferably, the positioning component includes multiple positioning rods, which are respectively movably mounted on the movable ring. Each of the multiple positioning rods has a stop block fixedly mounted on its outer side. A spring is fixedly mounted between the stop block and the movable ring. The spring is sleeved on the outer side of the positioning rod. Multiple positioning holes are opened on opposite sides of the two circular blocks. One end of the positioning rod is inserted into the inner cavity of the corresponding positioning hole.

[0008] By adopting the above technical solution, in order to improve the docking strength between the circular block and the movable ring, the circular block is fixed inside the movable ring, so that when the fixed plate is subjected to force, the force can be directly transmitted to the movable ring, so that the two movable rings exert force on the hydraulic bag together, and the hydraulic bag and hydraulic chamber are used to achieve the purpose of shock absorption.

[0009] Preferably, an abutment block is fixedly installed at the other end of the positioning rod, and the abutment block is cylindrical.

[0010] By adopting the above technical solution, it is possible to facilitate the application of force to the positioning rod, control the separation of the positioning rod from the round block, and thus facilitate the subsequent disassembly of components such as the round block.

[0011] Preferably, the outer wall of the contact block has a number of evenly distributed anti-slip textures.

[0012] By adopting the above technical solution, the friction of the outer wall of the contact block can be increased to avoid slippage during subsequent force application.

[0013] Preferably, each of the two circular blocks is fixedly mounted with a screw on the side away from each other, and each of the two screws is threaded with a threaded sleeve on its outer side. The two threaded sleeves are respectively fixedly connected to the outer wall of the corresponding fixed disk on the side away from each other.

[0014] By adopting the above technical solution, the distance between the two fixed plates can be adjusted to facilitate the installation of the overall shock absorption structure.

[0015] Preferably, each of the two screws has a round shaft fixedly installed at one end opposite to the other, and the two round shafts pass through the corresponding round blocks and are rotatably connected to the corresponding round blocks.

[0016] By adopting the above technical solution, it is possible to easily adjust the horizontal angle of components such as the fixing plate, thus facilitating subsequent fixing and installation.

[0017] Preferably, the outer wall of the circular block is provided with an external thread, and the inner wall of the movable ring is provided with an internal thread. The circular block is threadedly connected to the inner cavity of the movable ring through the external and internal threads.

[0018] By adopting the above technical solution, the connection strength between the circular block and the movable ring can be improved, and the subsequent disassembly operation can be facilitated.

[0019] Preferably, the outer diameter of the movable ring is the same as the inner diameter of the outer pad.

[0020] By adopting the above technical solution, the movable ring is limited so that it can only move vertically, thus providing a stable shock absorption effect.

[0021] The beneficial effects of this utility model are as follows: By setting a movable ring, the internal thread on the movable ring is threadedly connected to the external thread on the circular block, and the positioning is further achieved by inserting the positioning rod into the positioning hole, thereby ensuring that the whole is formed into a cylindrical shape. Subsequently, the fixed plate is used to cooperate with the fixed hole to realize the installation at both ends. Subsequently, the hydraulic bag and hydraulic cavity are used to achieve shock absorption. Even after the two circular blocks, fixed plate and other components are removed, when installing them, the hydraulic bag and hydraulic cavity are used to achieve shock absorption. A single hydraulic bag and hydraulic cavity can achieve the shock absorption effect in both states, ensuring the shock absorption effect while reducing production costs, and is suitable for widespread promotion and use.

[0022] By incorporating positioning rods, positioning holes, and springs, multiple abutment blocks are pressed during the threaded connection between the round block and the movable ring. This causes each abutment block to move its corresponding positioning rod, which in turn moves a stop block synchronously. Simultaneously, the stop block stretches its corresponding spring. After the threaded connection between the round block and the movable ring is completed, the abutment blocks are released, allowing the positioning rods to reset under the elastic force of their respective springs. This allows the positioning rods to insert into the positioning holes on the round block, achieving positioning between the round block and the movable ring. This dual cooperation with the threaded connection enhances the installation strength between the round block and the movable ring. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] As shown in the figure, this embodiment provides an engine hydraulic shock absorber, including an outer pad 1. The outer pad 1 has a hollow interior, and movable rings 2 are movably installed near the top and bottom of the inner cavity of the outer pad 1. A hydraulic bag 4 is installed between the two movable rings 2. The hydraulic bag 4 is annular and has a hydraulic cavity 5 inside. A circular block 6 is movably installed through the two movable rings 2. A positioning component is provided on the circular block 6, and a fixing plate 11 is installed on the side of the two circular blocks 6 that is far apart from each other. The fixing plate 11 has multiple fixing holes 12.

[0031] In this embodiment, when in use, the two fixed plates 11 are first connected to the two ends of the shock absorber to install the overall shock absorber structure. During subsequent shock absorption, the two fixed plates 11 transmit force, and the vibration force is directly transmitted to the movable ring 2. The two movable rings 2 apply force to the hydraulic bag 4 and the hydraulic cavity 5 together, and the hydraulic bag 4 and the hydraulic cavity 5 are used to achieve the effect of hydraulic shock absorption, and the shock absorption reset is achieved through the hydraulic bag 4 and the hydraulic cavity 5.

[0032] If the shock-absorbing structure needs to be assembled, the two round blocks 6 need to be removed from the corresponding movable rings 2 respectively, and the outer pad 1, movable ring 2, hydraulic bag 4 and other components need to be assembled. After assembly, the vibration force is directly transmitted to the movable ring 2, and the movable ring 2 still uses the hydraulic bag 4 and hydraulic chamber 5 to achieve the shock absorption effect.

[0033] As an optional implementation, the positioning assembly includes multiple positioning rods 16, which are movably mounted through the movable ring 2. Each positioning rod 16 has a stop 17 fixedly mounted on its outer side. A spring 18 is fixedly mounted between the stop 17 and the movable ring 2. The spring 18 is sleeved on the outer side of the positioning rod 16. Multiple positioning holes 13 are opened on opposite sides of the two circular blocks 6. One end of the positioning rod 16 is inserted into the inner cavity of the corresponding positioning hole 13.

[0034] In this embodiment, by embedding multiple positioning rods 16 on the movable ring 2 into the positioning holes 13 on the circular block 6, the positioning operation between the circular block 6 and the movable ring 2 is realized, avoiding the circular block 6 from rotating inside the movable ring 2 and causing instability. During subsequent disassembly, it is only necessary to press the multiple positioning rods 16 to pull the positioning rods 16 out of the positioning holes 13. After pressing, the positioning rods 16 will drive the stop block 17 to stretch the corresponding spring 18. The elastic force of the spring 18 can be used to easily drive the positioning rods 16 to reset and perform a repositioning operation.

[0035] As an optional implementation, a contact block 14 is fixedly installed at the other end of the positioning rod 16, and the contact block 14 is cylindrical.

[0036] In this embodiment, the contact block 14 is designed so that when the worker applies force, there is no need to contact the positioning rod 16, which makes it convenient for the worker to apply force.

[0037] As an optional implementation, the outer wall of the contact block 14 is provided with a number of evenly distributed anti-slip textures 15.

[0038] In this embodiment, the use of multiple anti-slip textures 15 can effectively increase the friction of the outer wall of the contact block 14, so that the worker can avoid slipping when applying force.

[0039] As an optional implementation, screws 9 are fixedly installed on the opposite side of the two circular blocks 6, and threaded sleeves 10 are threadedly connected to the outer side of the two screws 9. The opposite side of the two threaded sleeves 10 are respectively fixedly connected to the outer wall of the corresponding fixed plate 11.

[0040] In this embodiment, by utilizing the threaded connection between the screw 9 and the threaded sleeve 10, the fixed plate 11 can be moved vertically by rotating the threaded sleeve 10, thereby adjusting the distance between the fixed plate 11 and the circular block 6. This allows the overall shock absorption structure to be installed in areas of different sizes to carry out shock absorption operations, improving the versatility and convenience of the overall shock absorption structure installation.

[0041] As an optional implementation, each of the two screws 9 has a round shaft 8 fixedly installed at one end opposite to the other. The two round shafts 8 pass through the corresponding round blocks 6 and are rotatably connected to the corresponding round blocks 6.

[0042] In this embodiment, the rotational connection between the circular shaft 8 and the circular block 6 allows the fixed plate 11 to be adjusted horizontally after its position is adjusted, so that the fixing holes 12 on the fixed plate 11 can be aligned with the installation position for subsequent fixing and installation.

[0043] As an optional implementation, the outer wall of the circular block 6 is provided with an external thread 7, and the inner wall of the movable ring 2 is provided with an internal thread 3. The circular block 6 is threadedly connected to the inner cavity of the movable ring 2 through the external thread 7 and the internal thread 3.

[0044] In this embodiment, the threaded connection between the circular block 6 and the movable ring 2 ensures the connection strength between the circular block 6 and the movable ring 2, while facilitating subsequent disassembly. Furthermore, in conjunction with the positioning component, the fixing effect between the circular block 6 and the movable ring 2 is further improved, ensuring the strength of the overall shock absorption structure.

[0045] As an optional implementation, the outer diameter of the movable ring 2 is set to be the same as the inner diameter of the outer pad 1.

[0046] In this embodiment, this setting limits the movement of the movable ring 2 inside the outer pad 1, so that the movable ring 2 can only move vertically inside the outer pad 1 and cannot tilt or perform other measures, thus ensuring the shock absorption effect.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of the invention. All such changes and modifications fall within the scope of the invention as claimed, which is defined by the appended claims and their equivalents.
