Description

Technical Field

[0001] The utility model relates to a vibration reduction device with a rubber spring in a generator, in particular to a vibration reduction seat.

[0002] The utility model also relates to a generator. Background Art

[0003] The shock-absorbing seat is generally a component connected between the power unit and the fixed bracket of the generator. The shock-absorbing pad made of deformable rubber on the shock-absorbing seat plays a role in reducing the vibration of the power unit transmitted to the fixed bracket. The structural composition of the shock-absorbing seat generally includes a dynamic mounting part for connecting the power unit, a static mounting part for connecting the fixed bracket, and a shock-absorbing pad connected between the dynamic mounting part and the static mounting part. When in use, the power unit connected to the dynamic mounting part and the fixed bracket connected to the static mounting part can move relative to each other through the shock-absorbing pad to achieve the reduction of vibration transmission. However, in actual use, it is found that the use of such a shock-absorbing seat is prone to damage to the generator due to excessive movement of the power unit or other components connected to the dynamic mounting part, which may collide with other components of the generator, or cause the shock-absorbing pad of the shock-absorbing seat to be overstretched and damaged, thereby affecting the normal use of the entire generator. For example, the above problems are very likely to occur in vehicle-mounted generators.

[0004] Chinese patent document CN 219809357 U discloses a shock-absorbing seat and a generator, comprising: a first connecting plate, one side of which is bent to form a first inclined plate, and the first inclined plate is inclined upward at one end away from the first connecting plate; a second connecting plate, which is arranged above the first inclined plate, and the bottom of the second connecting plate is bent to form a second inclined plate, and the second inclined plate is inclined toward the first connecting plate; a shock-absorbing block, which is arranged between the first inclined plate and the second inclined plate and is connected to the first inclined plate and the second inclined plate respectively; and a limiting plate, which is detachably arranged on the second connecting plate, and the bottom of the limiting plate is provided with a hook tongue, and the hook tongue can hook the first inclined plate upward. When in use, when the second connecting plate is pulled upward during the vibration of the engine, due to the existence of the limiting plate, when the hook tongue hooks the second inclined plate, the maximum upward displacement of the second connecting plate will be limited, thereby avoiding the safety problem caused by the engine hitting the fuel tank due to excessive vibration amplitude, and improving safety.

[0005] Although the shock absorber seat of the prior art solves the problem of the engine vibrating too much and hitting the fuel tank, the structure of the entire shock absorber seat is relatively complex and the processing cost is relatively high. Utility Model Content

[0006] The utility model aims to provide a shock-absorbing seat to solve the problem in the prior art that parts of a generator connected to the shock-absorbing seat are easily damaged by impact due to excessive movement.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a shock-absorbing seat, including a dynamic mounting part, a static mounting part and a shock-absorbing pad, wherein the shock-absorbing pad is connected between the dynamic mounting part and the static mounting part, the dynamic mounting part is fixedly provided with a first limiting part, and the static mounting part is fixedly provided with a second limiting part cooperating with the first limiting part for at least limiting the lateral displacement and longitudinal displacement of the dynamic mounting part.

[0008] The beneficial effect of this basic solution is that through the cooperation of the first limiting part and the second limiting part, the lateral displacement and longitudinal displacement of the movable mounting part are limited, thereby avoiding the movable mounting part from having excessive movement amplitudes in both the lateral and longitudinal directions, thereby avoiding the power unit or other components of the generator connected to the movable mounting part from being damaged by impact due to excessive movement amplitude, and avoiding the shock-absorbing pad from being damaged due to excessive stretching, thereby improving the shock-absorbing effect of the shock-absorbing seat and extending the service life of the shock-absorbing seat, which is conducive to further improving the safety of the generator.

[0009] Preferably, the first limiting portion includes a limiting plate extending toward the static mounting part, the limiting plate is provided with a limiting hole, and the second limiting portion includes a limiting block penetrating the limiting hole, and a limiting gap is provided between the circumference of the limiting block and the inner wall of the limiting hole. With such a setting, the limiting block can move in the limiting hole along the radial direction of the limiting hole due to the existence of the limiting gap, so that the movement range of the dynamic mounting part is limited by the movement of the limiting block in the limiting hole, which is conducive to simplifying the structure.

[0010] Preferably, a fixing bolt for fixing the static mounting member is arranged between the second limiting portion and the shock absorbing pad on the static mounting member. With such an arrangement, the second limiting portion is conveniently connected to the first limiting portion, and the processing difficulty of the shock absorbing seat is reduced.

[0011] Preferably, the first limiting part is integrally formed with the movable mounting member. This arrangement facilitates the processing and forming of the first limiting part and reduces the number of connection steps.

[0012] Preferably, the second limiting portion is integrally formed with the static mounting member. This arrangement facilitates the processing and forming of the second limiting portion and reduces the number of connection steps.

[0013] Preferably, a connecting bolt is arranged on a side of the second limiting portion away from the fixing bolt. Such an arrangement is conducive to enhancing the structural stability of the static mounting member and the second limiting portion, thereby improving the reliability of the shock absorbing seat.

[0014] Preferably, it further comprises a support member connected to the static mounting member, and the support member is provided with a clearance hole for accommodating the movement of the limit plate. With such a configuration, the clearance hole can reduce the interference of the limit plate on the connection between the static mounting member and the support member, and at the same time, the normal use of the original shock-absorbing seat can be ensured within the installation space of the original shock-absorbing seat, so that the improved shock-absorbing seat can directly replace the original shock-absorbing seat.

[0015] Another object of the utility model is to provide a generator which can prevent the power part or other parts of the generator connected to the shock-absorbing seat from being damaged by impact due to excessive movement.

[0016] In order to achieve the above object, the utility model provides a generator, comprising any one of the above-mentioned shock absorbing seats.

[0017] The utility model has the following beneficial effects:

[0018] 1. By using the utility model, the movement range of the movable mounting part of the shock-absorbing seat is limited in multiple directions, thereby avoiding the problem that the parts of the generator installed on the shock-absorbing seat have excessive movement range due to external force or abnormal operation and hit the adjacent parts. At the same time, it also avoids the situation that the shock-absorbing pad of the shock-absorbing seat is damaged due to excessive stretching, thereby improving the safety of the generator.

[0019] 2. By arranging the first limiting part on the dynamic mounting part and the second limiting part on the static mounting part, no new independent parts are added to the entire shock absorbing seat, thereby making the structure of the entire shock absorbing seat simple and convenient for processing and manufacturing.

[0025] Definition: The lateral displacement refers to the displacement of the movable mounting part in the horizontal direction when the shock absorber is installed. The longitudinal displacement refers to the displacement of the movable mounting part in the plumb line direction when the shock absorber is installed.

[0026] The following is further described in detail through specific implementation methods:

[0027] The figure marks in the drawings of the specification include: power unit 1, shock absorbing seat 2, dynamic mounting part 21, shock absorbing pad 22, static mounting part 23, support part 24, fixing bolt 25, connecting bolt 26, limiting gap 27, dynamic connecting part 211, dynamic inclined plate part 212, limiting plate 213, limiting hole 214, static inclined plate part 231, static connecting part 232, limiting block 233.

[0028] The embodiment is basically as shown in the attached Figures 1 to 5 As shown: A generator includes a power unit 1 and a fixed bracket, and a shock-absorbing seat 2 is installed between the bottom of the power unit 1 and the fixed bracket. The shock-absorbing seat 2 includes a dynamic mounting member 21, a static mounting member 23 and a shock-absorbing pad 22. The static mounting member 23 is located at the lower side of the dynamic mounting member 21, and the shock-absorbing pad 22 is connected between the dynamic mounting member 21 and the static mounting member 23. In this embodiment, the dynamic mounting member 21 includes a vertically arranged dynamic connection part 211, an inclined dynamic inclined plate part 212 and a first limiting part from top to bottom. The dynamic connection part 211, the dynamic inclined plate part 212 and the first limiting part are integrally formed, so that the entire dynamic mounting member 21 is a bent plate-shaped member. The dynamic mounting member 21 is connected to the power unit 1 of the generator through the dynamic connecting part 211. The first limiting part includes a vertically arranged limiting plate 213, so that the limiting plate 213 is extended toward the static mounting member 23. A limiting hole 214 is provided on the limiting plate 213. In this embodiment, the static mounting member 23 includes a static inclined plate portion 231 corresponding to the dynamic inclined plate portion 212, and also includes a static connection portion 232. A second limiting portion is provided on the side of the static connection portion 232 away from the static inclined plate portion 231. The static inclined plate portion 231, the static connection portion 232 and the second limiting portion are integrally formed, so that the entire static mounting member 23 is a bent plate-shaped member. The shock absorbing pad 22 is bonded between the dynamic inclined plate portion 212 and the static inclined plate portion 231. In this embodiment, the shock absorbing pad is preferably an elastic rubber pad. The second limiting portion cooperates with the first limiting portion to limit at least the lateral displacement and longitudinal displacement of the dynamic mounting member 21.

[0029] The second limiting portion includes a limiting block 233 that is inserted into the limiting hole 214. A limiting gap 27 is set between the circumference of the limiting block 233 and the inner wall of the limiting hole 214, so that the limiting block 233 can move a certain distance in the radial direction of the limiting hole 214 in the limiting hole 214, thereby limiting the lateral displacement and longitudinal displacement of the dynamic mounting member 21. A fixing bolt 25 for fixing the static mounting member 23 is set between the second limiting portion and the shock absorbing pad 22 on the static mounting member 23. A connecting bolt 26 is set on the side of the second limiting portion away from the fixing bolt 25, so that both ends of the limiting block 23 are fixed by bolts. The lower part of the static mounting member 23 is connected to the support member 24. Specifically, the static mounting member 23 is connected and fixed to the support member 24 by the fixing bolt 25 and the connecting bolt 26. The support member 24 is provided with a clearance hole for accommodating the movement of the limiting plate 213 , thereby preventing the support member 24 from interfering with the movement of the limiting plate 213 .

[0030] By using the utility model, the movement range of the movable mounting member 21 of the shock-absorbing seat 2 is limited in multiple directions, thereby avoiding the problem that the components of the generator installed on the shock-absorbing seat 2 collide with adjacent components due to excessive movement due to external force or abnormal operation, and also avoiding the situation that the shock-absorbing pad 22 of the shock-absorbing seat 2 is damaged due to excessive stretching, thereby improving the safety of the generator. In addition, from the perspective of the structural composition of the shock-absorbing seat 2, the number of independent parts of the improved shock-absorbing seat 2 does not increase, thereby avoiding the problem of increased assembly difficulty and easy loss of parts due to the increase of independent parts.

[0031] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
