Description

Technical Field

[0001] This utility model relates to a shock absorber seat, specifically to a shock absorber seat and a general-purpose engine-driven work machine. Background Technology

[0002] Vibration damping mounts absorb and disperse mechanical vibration energy through their elastic properties, preventing vibration from being directly transmitted to adjacent structures or objects. This reduces the impact on the surrounding environment and minimizes damage to the equipment itself. Vibration damping mounts on generators are typically connected between the generator's power unit and the fixed support. During use, the damping pads reduce the transmission of vibration between the power unit and the fixed support. However, in practical use, it has been found that such vibration damping mounts are prone to damage when the power unit or other components connected to the moving mount move excessively, impacting other parts of the generator. Alternatively, the damping pads may become overstretched and break, affecting the normal operation of the entire generator. Vehicle-mounted generators are particularly susceptible to these problems.

[0003] To address the aforementioned problems, Chinese patent document CN219809357U discloses a vibration damping seat, comprising a first connecting plate, a second connecting plate, a vibration damping block, and a limiting plate. The vibration damping block is installed between the first and second inclined plates and connected to both plates. The limiting plate is detachably mounted on the second connecting plate, and a hook is provided at the bottom of the limiting plate, which can hook upwards onto the first inclined plate. Due to the presence of the limiting plate, when the hook hooks onto the second inclined plate, it limits the maximum upward displacement of the second connecting plate, thereby avoiding safety issues caused by excessive vibration leading to engine impact with the fuel tank, and improving safety. This utility model also provides a generator, including the aforementioned vibration damping seat, which improves the safety during operation and extends the service life of the entire generator.

[0004] For example, Chinese patent document CN222229293U discloses a vibration damping base and a generator, including a dynamic mounting component, a static mounting component, and a vibration damping pad. The vibration damping pad is connected between the dynamic mounting component and the static mounting component. The dynamic mounting component is fixedly provided with a first limiting part, and the static mounting component is fixedly provided with a second limiting part that cooperates with the first limiting part to at least limit the lateral and longitudinal displacement of the dynamic mounting component. This solution solves the problem in the prior art that components connected to the vibration damping base on the generator are easily damaged by impact due to excessive movement.

[0005] In the aforementioned prior art, additional limiting components are used to restrict the displacement of the mounting plates at both ends of the shock absorber, thereby preventing excessive movement of components during operation and potential impact damage. However, all of the aforementioned prior art suffers from structural complexity. Utility Model Content

[0006] To address the technical problem of complex structures in existing technologies, this utility model provides a shock-absorbing seat, comprising a dynamic mounting component and a static mounting component. A shock-absorbing component is provided between the dynamic mounting component and the static mounting component. A static mounting portion is provided at the end of the static mounting component away from the shock-absorbing component, and a dynamic mounting portion is provided at the end of the dynamic mounting component away from the shock-absorbing component. The static mounting portion and the dynamic mounting portion are arranged opposite to each other, and a limiting component is provided between the static mounting portion and the dynamic mounting portion to restrict the circumferential movement of the dynamic mounting component.

[0007] In existing technologies, because the moving and stationary mounting parts are staggered, additional mounting positions are needed for the limiting components to connect between them, resulting in complex vibration damper structures. In this solution, the stationary and moving mounting parts are positioned opposite each other. Besides facilitating the installation of the vibration damper between the moving and stationary mounting parts, these parts also provide space for the limiting components between them. Compared to existing technologies, this eliminates the need for additional mounting positions for the limiting components, simplifying the vibration damper structure and manufacturing process.

[0008] Preferably, the limiting member is detachably connected to the moving or stationary mounting part. In this design, the detachable connection facilitates the installation and replacement of the limiting member.

[0009] Preferably, the moving mounting part has a mounting position, and the stationary mounting part has a limiting through hole corresponding to the mounting position. In this design, the mounting position and the stationary mounting part facilitate the installation of the limiting part, resulting in a simple structure.

[0010] Preferably, one end of the limiting member is connected to the movable mounting part, and the other end of the limiting member is intermittently fitted with the limiting through hole. This design facilitates the installation of the limiting member and has a simple structure.

[0011] Preferably, the end of the limiting member extending from the driven mounting portion toward and through the limiting through hole is provided with a boss to prevent the end from exiting the limiting through hole. This design can prevent the limiting member from exiting the limiting through hole, thereby ensuring that the limiting member can limit the displacement of the driven mounting portion, and also preventing the problem of the shock absorber tearing due to excessive displacement of the driven mounting portion.

[0012] Preferably, the movable mounting part is provided with a mounting hole, and a fastener for connecting to the limiting member is provided in the mounting hole. In this solution, the fastener serves as a connector between the movable mounting part and other components, while also reinforcing the connection between the movable mounting part and the limiting member, resulting in a simpler structure and lower cost.

[0013] Preferably, the limiting member has a hollow portion that matches the fastener. In this design, the connection between the limiting member and the fastener is achieved by utilizing the hollow portion on the limiting member, which helps in adjusting manufacturing tolerances.

[0014] Secondly, this utility model also provides a universal engine-driven work machine, including a work device, a frame arranged around the work device, and a base supporting the work device; wherein: it also includes the aforementioned shock-absorbing seat, with a static mounting part connected to the base and a dynamic mounting part connected to the work device.

[0015] In this solution, the installation of the shock-absorbing seat can effectively reduce the vibration intensity of the working device, and at the same time, it can also limit the displacement of the moving mounting part, thereby avoiding the problem of the working device hitting other surrounding parts due to excessive vibration amplitude, and also improving the service life of the working machine.

[0016] Preferably, four shock-absorbing seats are provided on the base, and the four shock-absorbing seats are located at the four corners of the working machine. This solution can further and effectively reduce the vibration intensity of the working device.

[0017] Preferably, the centerlines of the four shock absorber seats passing through the limiting holes intersect, and the included angle between any two of the centerlines is within the range of 90±40°. This design ensures that the shock absorber seats have a certain buffer when subjected to impact along the positioning axis direction, while preventing the shock absorber components from tearing.

[0018] This utility model has the following beneficial effects:

[0019] 1. In addition to enabling the installation of the shock absorber seat with other components, the static mounting part and the dynamic mounting part of this utility model can also provide a limiting component between the dynamic mounting part and the static mounting part.

[0024] The following detailed description illustrates the specific implementation method:

[0025] The reference numerals in the accompanying drawings include: moving mounting part 1, moving mounting section 11, mounting position 12, shock absorber 2, static mounting part 3, static mounting section 31, limiting through hole 32, limiting part 4, boss 41, fastener 5, working device 6, base 7.

[0026] The basic implementation examples are as follows: Figure 1 As shown: The shock absorber seat includes a dynamic mounting part 1 and a static mounting part 3. Both the static mounting part 3 and the dynamic mounting part 1 are bent plates, that is, the two ends of the static mounting part 3 are set at a certain angle, and the two ends of the dynamic mounting part 1 are set at a certain angle.

[0027] A shock absorber 2 is provided between the movable mounting component 1 and the stationary mounting component 3, and the shock absorber 2 is located at the same end of the movable mounting component 1 and the stationary mounting component 3. A stationary mounting portion 31 is provided at the end of the stationary mounting component 3 away from the shock absorber 2, and a movable mounting portion 11 is provided at the end of the movable mounting component 1 away from the shock absorber 2. The stationary mounting portion 31 and the movable mounting portion 11 are arranged opposite to each other, and a limiting component 4 is provided between the stationary mounting portion 31 and the movable mounting portion 11 to restrict the circumferential movement of the movable mounting component 1. In this embodiment, the shock absorber 2 is an elastic rubber pad, and the shock absorber 2 is bonded between the stationary mounting component 3 and the movable mounting component 1.

[0028] The limiting member 4 is detachably connected to either the moving mounting part 11 or the stationary mounting part 31. Specifically, the moving mounting part 11 is provided with a mounting position 12, and the stationary mounting part 31 is provided with a limiting through hole 32 corresponding to the mounting position 12. One end of the limiting member 4 is connected to the moving mounting part 11, and the other end of the limiting member 4 is intermittently fitted with the limiting through hole 32.

[0029] The driven mounting portion 11 on the limiting member 4 extends toward and through the limiting through hole 32, and has a boss 41 at its end that restricts the end from exiting the limiting through hole 32. In this embodiment, the diameter of the boss 41 is larger than the diameter of the limiting through hole 32.

[0030] Based on the aforementioned shock absorber, this embodiment also provides a universal engine-driven work machine, including a work device 6, a frame surrounding the work device 6, a base supporting the work device 6, and a shock absorber. The static mounting part 31 is connected to the base 7, and the dynamic mounting part 11 is connected to the work device 6. Figure 2 As shown. In this embodiment, the working device is an engine, and the working machine is a generator.

[0031] Specifically, four shock absorbers are provided on the base 7, and the four shock absorbers are located at the four corners of the machine; the center lines of the four shock absorbers passing through the limiting through holes 32 are intersecting, and the included angle formed by each pair of the center lines is 90±40°.

[0032] The movable mounting part 11 is provided with a mounting hole, and a fastener 5 that connects to the limiting member 4 is provided in the mounting hole. The limiting member 4 is provided with a hollow part that matches the fastener 5.

[0033] The specific implementation process is as follows: During the use of the work machine, the shock absorber 2 on the shock absorber seat can reduce the vibration transmitted from the work device 6 to the frame. Furthermore, when the movement amplitude of the work device 6 is too large, the limiting member 4 of the shock absorber seat can restrict the displacement of the movable mounting part 11. Since the movable mounting part 11 is connected to the work device 6, the shock absorber seat can also limit the vibration amplitude of the work device 6 through the movable mounting part 11, thus preventing the work device 6 from colliding with surrounding components due to excessive movement. Simultaneously, because the limiting member 4 restricts the displacement of the movable mounting part 11, it can also prevent the shock absorber 2 from being overstretched and torn due to excessive displacement of the movable mounting part 11.
