[0020] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0021] The present application provides an electrically controlled suspension adjustable gas spring. The preferred embodiments of the electrically controlled suspension adjustable gas spring are described below in conjunction with the accompanying drawings.

[0022] Embodiment 1 This embodiment provides an electrically controlled suspension regulating gas spring. The controllable gas spring uses an additional release mechanism to control the switch at the top of the gas spring piston rod on the basis of the gas spring to achieve control of the gas spring stroke and stiffness. Controllable gas springs are widely used in many fields, such as automotive suspension systems, medical care beds, industrial automation robotic arms, etc.

[0023] When using existing controllable gas springs, most of them use a pull wire to control the top switch of the gas spring. For example, a micro motor is used to drive the winding rod to rotate. The winding rod is connected to the winding wire to pull the connecting rod. The connecting rod pulls the adjusting rod through the adjusting rope. The adjusting rod presses the adjusting tube through the pressure rod, thereby causing the inner tube body to expand and contract. This control method can realize the flexible use of gas springs, and further achieve the effect of automatic control of gas springs by adding automation equipment. There are still some problems with the pull wire control gas spring. For example, when the gas spring itself has a large force value, the control method of the pull wire control gas spring is more laborious to operate; at the same time, the pull wire control gas spring can only control the force of the gas spring in one direction, and cannot achieve the effect of gas spring suspension; the control method of the pull wire control gas spring lacks buffering when the gas spring is started, and there is a risk of injuring the operator. In the above example, the structure of controlling the gas spring by pulling the pull wire by a micro motor has a high manufacturing cost, a higher failure rate compared to the mechanical structure, and a larger volume.

[0024] Furthermore, in order to overcome the problems of the existing wire-type controllable gas springs, such as being laborious to operate when facing gas springs with large force values, having a single force direction, being unable to achieve a suspension effect, being expensive, and having a relatively high failure rate, this embodiment proposes a mechanical structure to control the gas spring 1 to achieve stroke control of the gas spring 1. The stroke of the gas spring 1 is controlled by pressing and releasing the push switch 11 of the gas spring 1 through a simpler rocker arm 22 mechanism. At the same time, a telescopic rod 32 mechanism for controlling the rocker arm 22 is provided on the rocker arm 22 mechanism. The setting position of the telescopic rod 32 mechanism is consistent with the length direction of the gas spring 1, which relatively reduces the volume.

[0025] Reference Figure 3 The connecting seat 21 is in a stepped shape as a whole, and a gas spring connecting hole 24 is provided on the plane threadedly connected to the gas spring 1. The end of the gas spring 1 where the push switch 11 is located is inserted into the gas spring connecting hole 24 and threadedly connected; the two plate-like structures connected to the plane where the gas spring connecting hole 24 is located are arranged opposite to each other, and the two plate-like structures are the same. There is a swing cavity 23 between the two plate-like structures, and after the gas spring 1 is fixedly connected to the connecting seat 21, the push switch 11 of the gas spring 1 extends into the swing cavity 23; the two plate-like structures are connected to the plane where the gas spring connecting hole 24 is located. A hinge hole for the rocker arm 22 is protrudingly provided on one side of the connecting seat 21 as a whole; a fixing boss 25 is provided on the other side of the connecting seat 21 away from the hinge hole of the rocker arm 22, and the fixing boss 25 is extended from the plane where the gas spring connecting hole 24 is located, and a step is formed between the two; a second hinge hole 13 is provided at the end of the connecting seat 21 away from the gas spring connecting hole 24; a telescopic through hole 251 and a fixing hole 252 are opened on the fixing boss 25, the telescopic through hole 251 is used to pass the telescopic rod 32, and the fixing hole 252 is used to fix the sleeve 31.

[0026] Continue to refer to the attached Figure 3 A through hole is provided at each end of the rocker arm 22 for passing a pin shaft. The rocker arm 22 is passed through the variable cavity of the connecting seat 21. The through hole at one end is hinged to the hinge hole of the rocker arm 22 through the first pin shaft 221. The rocker arm 22 rotates around the first pin shaft 221 in the swing cavity 23. A first cotter pin 222 is passed through one end of the first pin shaft 221 to prevent the first pin shaft 221 from falling off, and a gasket 225 is arranged between the first cotter pin 222 and the connecting seat 21; the other end of the rocker arm 22 is hinged to the hinge hole of the telescopic rod 32 through the second pin shaft 223, a second cotter pin 224 is passed through one end of the second pin shaft 223 to prevent the second pin shaft 223 from falling off, and a gasket 225 is arranged between the second cotter pin 224 and the telescopic rod 32.

[0027] Continue to refer to the attached Figure 3 The telescopic rod assembly 3 includes a telescopic rod 32 and a sleeve 31. The sleeve 31 has a planar structure fixedly connected to the fixed boss 25 and has two through holes, which are fixedly connected to the two fixing holes 252 on the fixed platform by bolts; the telescopic rod 32 is inserted into the sleeve 31, and one end of the telescopic rod 32 has a hinge hole, which is hinged to the end of the rocker arm 22 away from the hinge hole of the rocker arm 22; in a stationary state, the side of the rocker arm 22 close to the gas spring 1 abuts against the press switch 11 of the gas spring 1.

[0028] Continue to refer to the attached Figure 3In order to realize that the electric-controlled suspension regulating gas spring of this embodiment has two force directions and realizes the suspension effect during the stroke, this embodiment also includes a buffer component 4, a first hinge hole 26 is set at the end of the gas spring 1 away from the rocker arm 22 mechanism, and a second hinge hole 13 is set at the end of the connecting seat 21 of the rocker arm 22 mechanism away from the fixing hole 252 of the gas spring 1, and the axes of the first hinge hole 26 and the second hinge hole 13 are set in parallel; a first stepped shaft 42 is passed through the first hinge hole 26, and a second stepped shaft 43 is passed through the second hinge hole; the first stepped shaft 42 and the second stepped shaft 43 have the same structure. Taking the first stepped shaft 42 as an example, the two ends of the first stepped shaft 42 are small diameter sections with equal outer diameters, and the middle It is a large diameter section with a larger outer diameter, one of the small diameter ends of which is inserted into the first hinge hole 26 and transitionally matched with the first hinge hole 26; similarly, one of the small diameter ends of the second stepped shaft 43 is inserted into the second hinge hole 13 and transitionally matched with the second hinge hole 13; after the first stepped shaft 42 is matched with the first hinge hole 26, the small diameter end of the first stepped shaft 42 matched with the first hinge hole 26 is fixed by a retaining spring 44 to prevent the first stepped shaft 42 from falling off, and the second stepped shaft 43 is fixed by a retaining spring 44 in the same manner; the first stepped shaft 42 and the second stepped shaft 43 are correspondingly arranged up and down on the whole of the electrically controlled suspension adjustment gas spring in this embodiment; the buffer assembly 4 also includes an elastic member 41 arranged on the first stepped shaft 42 The elastic member 41 in this embodiment is a high-strength spring, one end of the elastic member 41 is sleeved on the small-diameter end of the first step shaft 42 and the other end is sleeved on the small-diameter end of the second step shaft 43. The small-diameter ends of the first step shaft 42 and the second step shaft 43 that cooperate with the elastic member 41 are fixed with retaining springs 44 to prevent the elastic member 41 from falling off; the elastic member 41 can provide a certain buffer in the initial stage of the stroke of the gas spring 1, and at the same time make the expansion and contraction of the gas spring 1 have a suspension effect during the complete stroke of the gas spring 1; it should be noted that the elastic member 41 needs to have a certain stretch when the gas spring 1 is fully retracted, so as to ensure that the gas spring 1 provides a certain amount of tension at the beginning of the extension stroke. A certain elastic force is applied to achieve a buffering effect; during the extension of the gas spring 1 during its stroke, the elastic member 41 is stretched to provide a force in the opposite direction of the extension of the gas spring 1. The value of the elastic force generated by the elastic member 41 is selected according to the force value parameter of the gas spring 1 to ensure the normal extension of the gas spring 1. During the retraction of the gas spring 1 during its stroke, the gas spring 1 is subjected to the pulling force of the elastic member 41, and the gas spring 1 can be retracted with the help of a smaller external force, that is, the electrically controlled suspension-adjustable gas spring in this embodiment can be easily extended and retracted during the complete stroke to achieve a suspension effect, and can be suspended and retracted at any point in the stroke as needed. Compared with the current wire-type controllable gas spring, it is more convenient to use.

[0029] Furthermore, the telescopic rod assembly 3 in the present embodiment is a push-pull electromagnet, and the telescopic rod 32 is externally connected to an electrical control system. The operator can control the telescopic movement of the telescopic rod 32 mechanism through a control button, thereby controlling the telescopic movement of the gas spring 1. The advantage of this structure is that it simplifies the operator's operating steps for the gas spring 1, and the control of the control button can complete the control of the electrically controlled suspension adjustment gas spring of the present embodiment.

[0030] The motion process of the electronically controlled suspension regulating gas spring in this embodiment: The operator presses the control button, the push-pull electromagnet is energized, the telescopic rod 32 moves upward relative to the sleeve 31, the telescopic rod 32 drives the rocker arm to rotate upward around the first pin shaft 221, and the rocker arm 22 presses the push switch 11 of the gas spring, and the gas spring 1 performs an extension stroke. During this process, the elastic member 41 continues to be stretched, providing a reaction force in the extension direction for the gas spring 1, ensuring the buffering of the gas spring 1 at the beginning of the extension stroke; during the extension process of the gas spring 1, the operator can release the control button at any time to stop the extension stroke of the gas spring 1. After the control button is released, the push-pull electromagnet loses power, the telescopic rod 32 returns to the initial position, and the rocker arm 22 releases the push switch 11 of the gas spring 1, and the gas spring 1 stops extending; the operator continues to press the control button, the push-pull electromagnet is energized, and the movement process after pressing the control switch is repeated. With the help of the elastic force of the elastic member 41 and the external force, the gas spring 1 performs a retraction stroke, and the operator can release the control button at any time to stop the retraction of the gas spring 1.

[0031] The electrically controlled suspension regulating gas spring in this embodiment uses a rocker mechanism, an elastic member and a push-pull electromagnet to control the extension and retraction stroke of the gas spring with a large force value. At the same time, it has a suspension effect during the extension and retraction process of the gas spring, and can be stopped at any time during the extension and retraction process of the gas spring. The electrically controlled suspension regulating gas spring in this embodiment has a simple structure, and each component can be easily manufactured and processed. The manufacturing cost is lower than that of the current wire-type controllable gas spring, and the mechanical structure is more stable.
