Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings to which the invention is attached.
The first embodiment is as follows: as shown in fig. 1 to 3, a shock absorbing device includes an upper housing 1, a movable plate 2, a suspension spring 3, a plurality of damping springs 4, a plurality of buffer springs 5, a suspension spring 6, and a mass 7.
The upper case 1 is cylindrical as a whole, and its cross section is circular. The upper shell 1 comprises an upper bottom plate and a lower bottom plate, and a hollow inner cavity surrounded by side walls is formed between the upper bottom plate and the lower bottom plate. The lower bottom plate is provided with a communication hole 9 for communicating the inner cavity with the outside of the upper shell 1, and the communication hole 9 is positioned in the center of the lower bottom plate.
The cross section of the movable plate 2 is circular. The movable disk 2 includes a main body 21, an additional body 22, and a plurality of balls 23. The main body 21 is disposed in the inner cavity of the upper case 1, the additional body 22 is connected to the main body 21 and located below the main body 21, and at least a part (lower part) of the additional body 22 is located in the communication hole 9. The balls 23 are movably installed on the lower surface of the main body, and the balls 23 are in rolling contact with the upper surface of the lower plate. For example, a mounting groove is formed on the lower surface of the movable plate 2, the upper portion of the ball 23 is mounted in the mounting groove, the lower portion of the ball 23 is exposed out of the movable plate 2, and the ball 23 is annularly arranged near the edge of the main body 21.
The suspension spring 3 is longitudinally arranged in the inner cavity, and one end (upper end) of the suspension spring is connected with the upper bottom plate of the upper shell 1. The other end (lower end) of the suspension spring 3 is a free end or is connected to the upper surface of the main body 21 of the movable plate 2. When the other end (lower end) of the suspension spring 3 is a free end, a plurality of the suspension springs 3 can be distributed; when the other ends (lower ends) of the suspension springs 3 are connected to the upper surface of the main body 21 of the movable tray 2, one to two suspension springs 3 are generally provided at the center of the movable tray 2. The suspension spring 3 can buffer the longitudinal vibration of the movable plate 2.
The damping springs 4 are arranged in the inner cavity in the radial direction of the upper housing 1, and the respective damping springs 4 are uniformly distributed in the inner cavity. One end of the damping spring 4 is fixedly connected with the inner surface of the side wall of the upper case 1, and the other end is a free end and corresponds to the side surface of the main body 21 of the movable plate 2. When the movable disk 2 moves in the outer circumferential direction thereof, a damping function is achieved by the damping spring 4.
The buffer springs 5 are disposed in the communication hole 9 in the radial direction of the upper case 1, and the respective buffer springs 5 are uniformly distributed in the communication hole 9. The number of the buffer springs 5 may be less than the number of the damping springs 4. One end (outer end, i.e. the end farther from the center of the communication hole 9) of the buffer spring 5 is fixedly connected with the hole wall of the communication hole 9, and the other end (inner end, i.e. the end closer to the center of the communication hole 9) is a free end and corresponds to the side of the additional body 22; alternatively, one end (inner end, i.e., the end closer to the center of the communication hole 9) of the buffer spring 5 is fixedly connected to the side surface of the additional body 22, and the other end (outer end, i.e., the end farther from the center of the communication hole 9) is a free end and corresponds to the hole wall of the communication hole 9. The buffer spring 5 can be a common spring or a disc spring. The damping spring 5 mainly damps the movement of the movable disc 2 and partly damps the same.
The mass 7 is suspended below the additional body 22 by the suspension spring 6, and both the mass 7 and the suspension spring 6 are located outside the upper case 1. The mass 7 changes its suspension point by means of the movement of the movable disc 2.
Example two: as shown in fig. 4, a shock absorbing device is different from the first embodiment in that: the damping device further comprises a lower shell 8, wherein the lower shell 8 is connected with the upper shell 1 and is installed below the lower shell 8, and the outer side surface of the lower shell 8 is flush with the outer side surface of the upper shell 1, so that the mass block 7 is positioned in the lower shell 8.
The damping springs used in the two embodiments may be the existing damping springs, or the following novel damping springs.
As shown in fig. 5, the damping spring includes a first bellows 101, a second bellows 102, and a two-way valve 103.
A first cavity is formed in the first telescopic bag 101, a second cavity is formed in the second telescopic bag 102, the first cavity is communicated with the second cavity, and the two-way valve 103 is arranged at the communication position of the first cavity and the second cavity. The first cavity is filled with a damping energy-dissipating material 104 (such as asphalt cement) with certain fluidity, and a negative pressure environment is formed in the second cavity.
Specifically, the first bellows 101 and the second bellows 102 are arranged in parallel. The first bellows 101 comprises a first telescopic part and a first supporting part arranged at the bottom of the first telescopic part; the second bellows 102 includes a second bellows portion and a second support portion disposed at a bottom of the second bellows portion; the first supporting part and the second supporting part are connected to form a communication part of the first cavity and the second cavity. The first flexible portion includes that a plurality of stacks up the first bag monomer that sets up and inside intercommunication, and the second flexible portion includes that a plurality of stacks up the second bag monomer that sets up and inside UNICOM. The shape of the first single bag body and the shape of the second single bag body are both formed by curved surfaces.
The two-way valve 103 comprises a steel sheet with one end rotatably connected to the communication position of the first cavity and the second cavity and the other end being a free end.
The damping spring has an unstressed initial state. In the initial state, the damping energy dissipation material 104 filled in the first cavity extends the length of the first bellows 101 to a desired value, and the negative pressure environment formed in the second cavity shortens the length of the second bellows 102 to the minimum. When the first bellows 101 of the damping spring is stressed, the first bellows shortens and deforms, so that part of the damping energy-consuming material 104 flows into the second bellows 102 through the two-way valve 103, the second bellows 102 extends and deforms appropriately, and in the process, the damping energy-consuming material 104 achieves a buffering function. When the external force is lost, the damping energy-consuming material 104 flows back into the first bellows 101 through the two-way valve 103.
The damping spring can also adopt the following structural form: the damping spring comprises a bellows with a cavity, and the bellows is filled with a damping energy dissipation material 104 with fluidity and used for playing a role of buffering when the bellows is deformed under a force.
The telescopic bag of the damping spring is strip-shaped, and the length direction of the telescopic bag is vertical to the telescopic direction of the telescopic bag. It may be linear or arcuate. The expansion bag comprises an expansion part or a plurality of expansion parts which are arranged in parallel and are communicated with each other. Each expansion part comprises a plurality of bag monomers which are stacked and communicated with each other. The shape of the single capsule body is formed by a curved surface.
In an initial state, the filled damping energy dissipation material 104 maintains a certain uniform pressure on the bellows, and when a certain position of the bellows is stressed, the bellows is compressed and deformed, and the damping energy dissipation material 104 is forced to flow to other positions except the stressed position, and in the process, a buffer function is realized through the damping energy dissipation material 104.
When the damping spring is applied to the damping device of the present invention, a plurality of the damping springs may be arranged to be annularly distributed on the sidewall, thereby achieving a damping function in a circumferential direction. For example, four end-to-end damping springs may be provided, each damping spring being located within a range corresponding to a 90 ° central angle of the ring. At this time, each damping spring is arc-shaped, so that in the telescopic bag, the sectional area of each single bag body along the length direction of each single bag body is gradually reduced from the outside of the ring to the inside of the ring, namely the longitudinal section of the telescopic bag is approximately in a fan shape.
The damping device scheme of the invention realizes installation and use in a suspension mode, and realizes multiple damping functions through the swinging of the mass block 7, the movement of the movable disc 2 and the damping spring 4.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
