Description

Technical Field

[0001] This utility model relates to the field of air spring manufacturing technology, and specifically to an air spring assembly device. Background Technology

[0002] An air spring is a spring that utilizes the elasticity of air by filling a retractable, sealed container with compressed air. Air spring crimping is a manufacturing process that involves flipping the air bladder inside the air spring to wrap around the piston.

[0003] However, current air springs typically rely on manual or mechanical edge-rolling for edge rolling. Because these devices are structurally complex, they require first fixing the air spring in place, then activating an electric or hydraulic drive source to roll the air spring, and finally removing the air spring from the device. This significantly reduces the efficiency of the air spring's edge-rolling process. Utility Model Content

[0004] The purpose of this invention is to provide an air spring assembly device to solve the problems of complex operation and low air spring curling efficiency caused by the complex structure of existing curling devices.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An air spring assembly device, the air spring assembly device comprising:

[0007] A base, wherein an assembly space is provided on the base;

[0008] A rotary-to-linear conversion assembly is disposed in the assembly space and connected to the base. The rotary-to-linear conversion assembly is used to convert the input rotational motion into linear motion output.

[0009] A rotary drive assembly is connected to the rotary-to-linear conversion assembly, wherein the rotary drive assembly includes at least a rocker arm configured to provide rotational power to the rotary-to-linear conversion assembly when driven to rotate by an external force;

[0010] A limiting component, comprising a first limiting member and a second limiting member, wherein the first limiting member and the second limiting member are distributed relative to each other along both ends of the linear conversion component, and the first limiting member and the second limiting member are respectively used to limit and cooperate with both ends of the air spring, wherein the first limiting member is disposed on the base, and the second limiting member is drivenly connected to the linear output end of the rotary linear conversion component;

[0011] When the rotary drive assembly inputs rotational motion to the rotary-linear conversion assembly, the rotary-linear conversion assembly drives the second limiting member to perform reciprocating linear motion, thereby causing the air spring to perform extension and retraction motion, thus realizing the assembly and disassembly of the air spring.

[0012] According to the above-mentioned technical means, when the air spring is placed in the limiting assembly, the rotary drive assembly drives the air spring to perform telescopic movements, thereby enabling the assembly and disassembly of the air spring. For example, when the air spring is compressed, the air bladder in the air spring can flip over to wrap around the piston, completing the edge-rolling process of the air spring. When the air spring is extended, the air bladder in the air spring can separate from the piston, completing the disassembly of the air spring. This simplifies the structure of the air spring assembly device, and without the need for any drive source, the operator can rotate the rocker arm, causing the rotary linear conversion assembly to drive the second limiting member to perform reciprocating linear movements, thereby causing the air spring to telescopic, thus greatly improving the ease of assembly and disassembly of the air spring.

[0013] Furthermore, the rotary drive assembly also includes:

[0014] The first gear is connected to the rotary-linear conversion component in a transmission manner;

[0015] The second gear is rotatably connected to the base and meshes with the first gear, wherein the diameter of the second gear is smaller than the diameter of the first gear;

[0016] The rocker arm is connected to the second gear so as to drive the second gear to rotate by rotating the rocker arm.

[0017] Based on the above-mentioned technical means, the operating force required by the operator can be reduced by using a reasonable transmission ratio between the first gear and the second gear. This not only further reduces the structural complexity of the air spring assembly device, but also reduces the structural cost of the air spring assembly device.

[0018] Furthermore, the central axis formed by the first limiting member and the second limiting member is arranged parallel to the linear motion direction of the rotary linear conversion assembly.

[0019] According to the above technical means, when the second limiting member moves closer to or away from the first limiting member along the linear motion direction of the rotary linear conversion assembly, since there is no deviation angle between the central axis and the linear motion direction, the air spring can be extended and retracted so that the compressive force and elongation force on the air spring are both applied to the air spring from the axial direction, thereby improving the deformation uniformity of the air spring.

[0020] Furthermore, the rotary-linear conversion component includes:

[0021] A screw is rotatably connected to the base and is drively connected to the rotary drive assembly so that the rotary drive assembly drives the screw to rotate.

[0022] A sliding member is fitted onto the screw and is throttle-connected to the screw. A second limiting member is throttle-connected to the sliding member. When the screw rotates, the sliding member drives the second limiting member to reciprocate linearly along the length of the screw, so that the second limiting member moves closer to or away from the first limiting member.

[0023] According to the above-mentioned technical means, through the transmission and cooperation of the screw and the sliding member, the rotational motion of the screw is converted into the reciprocating linear motion of the sliding member along the screw, thereby driving the air spring to perform telescopic motion. This reduces the structural complexity of the rotation-to-linear conversion assembly.

[0024] Furthermore, the rotary-linear conversion component includes:

[0025] A slide rail, which is mounted on the base;

[0026] A slider, which is slidably connected to the slide rail;

[0027] A rack is connected to the slider and is arranged parallel to the slide rail. The second limiting member is connected to the rack or the slider in a transmission manner. The rack meshes with the first gear. When the first gear rotates, it drives the rack, causing the second limiting member to reciprocate linearly along the length of the rack, so that the second limiting member moves closer to or away from the first limiting member.

[0028] According to the above-mentioned technical means, the rotational motion of the first gear is converted into the reciprocating linear motion of the rack by meshing with the rack. Furthermore, the rack and the base are slidably engaged via a slide rail and a slider, which reduces the driving force required to move the second limiting member. In addition, the first gear can serve as a rotary transmission component in the rotary drive assembly or in the rotary-to-linear conversion assembly. By sharing components of the first gear, the structural complexity of the air spring assembly device can be further reduced.

[0029] Furthermore, the air spring assembly device also includes a scale disposed on the surface of the base, wherein the scale extends in a direction parallel to the linear movement direction of the second limiting member, so as to mark the reciprocating linear displacement of the second limiting member by means of the scale.

[0030] According to the above technical means, the linear displacement corresponding to the reciprocating linear motion of the second limiting member can be visually measured by the scale on the scale. Thus, when the air spring is determined to be compressed or extended to a preset length according to the scale, the operation of the rotary drive component can be stopped, so that the second limiting member maintains its current position.

[0031] Furthermore, the slider of the rotary-linear conversion assembly extends to the upper surface of the base and is positioned close to the scale graduations; or,

[0032] The air spring assembly device further includes a connecting member that is connected to the rotary linear conversion component (200) or the second limiting member, the connecting member extending to the upper surface of the base and being set close to the scale of the ruler.

[0033] According to the above technical means, the sliding member or connecting member is set close to the scale of the ruler, which makes it easier for the operator to accurately observe the reciprocating linear displacement of the second limiting member, and can improve the control accuracy of the extension and retraction length of the air spring.

[0034] Furthermore, the air spring assembly device also includes a protective cover, which engages with the base to form a telescopic space for the air spring to be embedded within it; wherein,

[0035] The telescopic space is completely provided along the straight direction of the second limiting member, and the protective cover is provided close to the first limiting member.

[0036] According to the above technical means, the protective cover is set close to the first limiting member and wraps around the air spring, so that the compressed air spring is in the protective cover, avoiding the situation where the air spring breaks during the compression process due to product defects or other factors, resulting in the splashing of parts, thereby improving the operational safety factor of the air spring assembly device.

[0037] Furthermore, the first limiting member is provided with a first limiting groove, the cross-sectional shape of the first limiting groove being arc-shaped, so that the air spring engages with the groove wall of the first limiting groove.

[0038] According to the above technical means, the setting of the first limiting groove can facilitate the air spring to be directly placed on the first limiting member in the vertical direction and to form a snap-fit ​​with the groove wall of the first limiting groove, thereby forming an axial limit on the first end of the air spring. The first limiting groove can improve the limiting accuracy of the air spring and facilitate the improvement of the loading and unloading efficiency of the air spring.

[0039] Furthermore, the second limiting member is provided with a second limiting groove, the cross-sectional shape of which is an arc, so that the air spring engages with the groove wall of the second limiting groove.

[0040] According to the above technical means, the setting of the second limiting groove can facilitate the air spring to be directly placed on the second limiting member in the vertical direction and to form a snap-fit ​​with the groove wall of the second limiting groove, thereby forming an axial limit on the second end of the air spring. The second limiting groove can improve the limiting accuracy of the air spring and facilitate the improvement of the loading and unloading efficiency of the air spring.

[0041] The beneficial effects of this utility model are:

[0042] This invention allows the two ends of the air spring to be respectively positioned and engaged with the first and second limiting members. The rotary drive assembly compresses the air spring, causing the air bladder within to flip and enclose the piston. Alternatively, the rotary drive assembly can extend the air spring, separating the air bladder from the piston and completing the disassembly of the air spring. This simplifies the structure of the air spring assembly device, and without the need for any drive source, the operator rotates the rocker arm, causing the rotary-linear conversion assembly to drive the second limiting member in a reciprocating linear motion, thereby extending and retracting the air spring. This significantly improves the ease of assembly and disassembly of the air spring. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0052] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation.

[0053] An air spring is a spring that utilizes the elasticity of air by filling a retractable, sealed container with compressed air. Air spring crimping is a manufacturing process that involves flipping the air bladder inside the air spring to wrap around the piston.

[0054] However, current air springs typically rely on manual or mechanical edge-rolling for edge rolling. Because these devices are structurally complex, they require first fixing the air spring in place, then activating an electric or hydraulic drive source to roll the air spring, and finally removing the air spring from the device. This significantly reduces the efficiency of the air spring's edge-rolling process.

[0055] Based on the aforementioned technical problems, this application proposes an embodiment that may include a base, a rotary-to-linear conversion component, a rotary drive component, and a limiting component. The base has an assembly space, and the rotary-to-linear conversion component is disposed in the assembly space and connected to the base. The rotary-to-linear conversion component converts input rotational motion into linear motion output. The rotary drive component is drively connected to the rotary-to-linear conversion component. The limiting component includes a first limiting member and a second limiting member, which are distributed opposite to each other along both ends of the linear conversion component. Both ends of an air spring are respectively fitted with the first limiting member and the second limiting member to limit their respective ends. The first limiting member is disposed on the base, and the second limiting member is drively connected to the linear output end of the rotary-to-linear conversion component. When the rotary drive component inputs rotational motion to the rotary-to-linear conversion component, the rotary-to-linear conversion component drives the second limiting member to perform reciprocating linear motion, thereby causing the air spring to extend and retract, realizing the assembly and disassembly of the air spring. Therefore, the rotary drive assembly compresses the air spring, causing the air bladder within the air spring to flip and enclose the piston. Alternatively, the rotary drive assembly can extend the air spring, separating the air bladder from the piston and completing the disassembly of the air spring. This embodiment simplifies the structure of the air spring assembly device, and without the need for any drive source, the operator rotates the rocker arm, causing the rotary-linear conversion assembly to drive the second limiting member in a reciprocating linear motion, thereby extending and retracting the air spring. This significantly improves the ease of assembling and disassembling the air spring.

[0056] Reference Figure 1-6 This application discloses an air spring assembly device, which may include a base 100, a rotary-to-linear conversion component 200, a rotary drive component 300, and a limiting component 400. The base 100 provides structural support for other components in the air spring assembly device besides itself. The rotary-to-linear conversion component 200, the rotary drive component 300, and the limiting component 400 are respectively disposed on the base 100. The rotary-to-linear conversion component 200 converts input rotational motion into linear motion for output. The rotary drive component 300 is drively connected to the rotary-to-linear conversion component 200 and inputs rotational driving force to the rotary-to-linear conversion component 200.

[0057] The base 100 has an assembly space 101, and the rotary-to-linear conversion assembly 200 is disposed in the assembly space 101 and connected to the base 100. For example, the rotary-to-linear conversion assembly 200 can be installed on the side wall of the assembly space 101. The rotary drive assembly 300 can include at least a rocker arm 330, which is configured to provide rotational power to the rotary-to-linear conversion assembly 200 when driven by an external force. In one example, the rocker arm 330 can be connected to a rotary transmission component in the rotary drive assembly 300, allowing an operator to manually rotate the rocker arm 330, causing the rotary drive assembly 300 to rotate as a whole and input rotational power to the rotary-to-linear conversion assembly 200.

[0058] The limiting component 400 may include a first limiting member 410 and a second limiting member 420, which are distributed opposite to each other along both ends of the linear conversion component. That is, the first limiting member 410 and the second limiting member 420 are respectively provided at both ends of the linear conversion component along its linear movement direction. The first limiting member 410 and the second limiting member 420 are respectively used to limit the ends of the air spring 700. Thus, both ends of the air spring 700 can be placed on the first limiting member 410 and the second limiting member 420 respectively. The first limiting member 410 is disposed on the base 100, and the second limiting member 420 is drive-connected to the linear output end of the rotary linear conversion component 200. Through the limiting engagement of both ends of the air spring 700 with the limiting component 400, the limiting component 400 can form a limit along the axial direction of the air spring 700. When the rotary drive assembly 300 inputs rotational motion to the rotary-linear conversion assembly 200, the rotary-linear conversion assembly 200 drives the second limiting member 420 to reciprocate linearly towards or away from the first limiting member 410, and drives one end of the air spring 700, which is limited and cooperates with the second limiting member 420, to reciprocate linearly towards or away from the other end of the air spring 700. This allows the air spring 700 to extend and retract along the axial direction.

[0059] In one example, the operator rotates the joystick 330 to activate the rotary drive assembly 300, causing the air spring 700 to compress, which in turn causes the air bladder in the air spring 700 to flip and enclose the piston. Alternatively, the operator can rotate the joystick 330 to activate the rotary drive assembly 300, causing the air spring 700 to extend, which separates the air bladder from the piston, thus disassembling the air spring 700.

[0060] In summary, the operator can place the air spring 700 into the limiting component 400, and without the need for any drive source, rotate the rocker arm 330 to cause the rotary linear conversion component 200 to drive the second limiting member 420 to perform reciprocating linear motion, thereby causing the air spring 700 to extend and retract. This reduces the structural complexity of the air spring assembly device and greatly improves the ease of assembly and disassembly of the air spring 700.

[0061] In one or more embodiments, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, the rotary drive assembly 300 may further include a first gear 310 and a second gear 320. The first gear 310 is pultrusively connected to the rotary-linear conversion assembly 200. The second gear 320 is rotatably connected to the base 100 and meshes with the first gear 310, wherein the diameter of the second gear 320 is smaller than the diameter of the first gear 310. The rocker arm 330 is pultrusively connected to the second gear 320, so as to drive the second gear 320 to rotate by rotating the rocker arm 330.

[0062] In this embodiment, the first gear 310 is drive-connected to the rotary-linear conversion assembly 200. This can be understood as the first gear 310 being the driven gear and the second gear 320 being the driving gear. The second gear 320 can be rotatably connected to the base 100 via bearings or other components. The second gear 320 is also drive-connected to the rocker arm 330. This can be understood as the central axis of the second gear 320 coinciding with the rotation axis of the rocker arm 330, and the rocker arm 330 being fixedly connected to the second gear 320.

[0063] When the rocker arm 330 is rotated under force, it drives the second gear 320, which is connected to the rocker arm 330, to rotate. The second gear 320 drives the first gear 310, which meshes with the second gear 320, to rotate. The first gear 310 then inputs rotational power to the rotary-linear conversion assembly 200, which is connected to the first gear 310. The diameter of the second gear 320 is smaller than the diameter of the first gear 310. When the rotational motion of the second gear 320 is transmitted to the first gear 310, the rotational speed of the first gear 310 decreases and the torque increases, thereby allowing it to output a greater rotational force to the rotary-linear conversion assembly 200. Thus, by setting a reasonable transmission ratio between the first gear 310 and the second gear 320, the required operating force of the operator can be reduced, and the linear motion rate of the second limiting member 420 can be slowed down. Furthermore, the high transmission accuracy of the meshing between the first gear 310 and the second gear 320 improves the control accuracy of the extension length of the air spring 700. This not only further reduces the structural complexity of the air spring assembly device but also reduces its structural cost.

[0064] In one or more embodiments, refer to Figure 2 As shown, the central axis formed by the first limiting member 410 and the second limiting member 420 is parallel to the linear motion direction of the rotary-linear conversion assembly 200. When the second limiting member 420 moves closer to or away from the first limiting member 410 along the linear motion direction of the rotary-linear conversion assembly 200, since there is no deviation angle between the central axis and the linear motion direction, the air spring 700 can be extended and retracted such that both the compressive force and the elongation force acting on the air spring 700 are axially applied to the air spring 700, thus improving the deformation uniformity of the air spring 700.

[0065] In one or more embodiments, refer to Figure 1 , Figure 2 , Figure 5 as well as Figure 6As shown, the rotary-linear conversion assembly 200 may include a screw 210 and a slider 220. The screw 210 is rotatably connected to the base 100 and is driveably connected to the rotary drive assembly 300, so that the rotary drive assembly 300 drives the screw 210 to rotate. The slider 220 is fitted onto the screw 210 and is driveably connected to the screw 210. The second limiting member 420 is driveably connected to the slider 220. When the screw 210 rotates, the slider 220 drives the second limiting member 420 to reciprocate linearly along the length direction of the screw 210, so that the second limiting member 420 moves closer to or further away from the first limiting member 410.

[0066] In this embodiment, the rotary-linear conversion assembly 200 may include a screw 210 and a slider 220. The two ends of the screw 210 can be mounted on the base 100 via bearings or other components, enabling the screw 210 to form a rotatable connection within the assembly space 101. The central axis formed by the first limiting member 410 and the second limiting member 420 is parallel to the length direction of the screw 210.

[0067] The screw 210 is driven by the rotary drive assembly 300, so that when the operator rotates the rocker arm 330, the screw 210 can be driven to rotate synchronously. For example, the screw 210 can be driven by the first gear 310, wherein the end of the screw 210 near the first gear 310 can be fixedly connected to the first gear 310, and the central axis of the first gear 310 coincides with the central axis of the screw 210. Thus, when the first gear 310 rotates, the screw 210 can be driven to rotate.

[0068] The slider 220 is fitted onto the screw 210 and is kinetically connected to the screw 210. In other words, the screw 210 and the slider 220 can form a lead screw and nut pair, so that when the screw 210 rotates and its position is limited by the base 100, the slider 220 can reciprocate linearly along the length direction of the screw 210, thereby reducing the structural complexity of the rotary-linear conversion assembly 200. In one example, when the rocker arm 330 rotates in a first direction, it drives the slider 220 to move linearly closer to the first limiting member 410. In another example, when the rocker arm 330 rotates in a second direction, it drives the slider 220 to move linearly away from the first limiting member 410.

[0069] The second limiting member 420 is connected to the sliding member 220 via a transmission connection. For example, the second limiting member 420 can be fixed to the sliding member 220 by means of bolts, welding, or screws. This allows the second limiting member 420 to simultaneously reciprocate linearly towards and away from the first limiting member 410 while the sliding member 220 is performing reciprocating linear motion. This enables the disassembly and assembly of the air spring 700.

[0070] In another or more embodiments, the rotary-linear conversion assembly 200 may include a slide rail, a slider, and a rack. The slide rail is disposed on the base 100. The slider is slidably connected to the slide rail, and the rack is connected to the slider and disposed parallel to the slide rail. The second limiting member 420 is pulsatorically connected to the rack or the slider. The rack meshes with the first gear 310. When the first gear 310 rotates, it drives the rack, causing the second limiting member 420 to reciprocate linearly along the length direction of the rack, so that the second limiting member 420 moves closer to or further away from the first limiting member 410.

[0071] In this embodiment, the slide rail and the slider are slidably coupled. The slide rail can be fixedly connected to the base 100, and the slider is fixedly connected to the rack. This allows the rack to slide directionally along the slide rail under force, reducing the driving force required for the rack to slide. The second limiting member 420 is connected to the rack or the slider, so that when the rack reciprocates linearly along the slide rail under external force, it synchronously drives the second limiting member 420 to move. For example, the second limiting member 420 can be fixed to the rack or the slider by bolts, welding, or screws. This allows the second limiting member 420 to reciprocate linearly towards and away from the first limiting member 410 simultaneously when the rack reciprocates linearly. This enables the disassembly and assembly of the air spring 700.

[0072] The rack meshes with the first gear 310, which is rotatably connected to the base 100. The central axis of the first gear 310 is parallel to the vertical direction. In one example, when the rocker arm 330 rotates in a first direction, it causes the rack to move linearly closer to the first limiting member 410. In another example, when the rocker arm 330 rotates in a second direction, it causes the rack to move linearly away from the first limiting member 410.

[0073] Based on the above structure, the rotational motion of the first gear 310 can be converted into the reciprocating linear motion of the rack. Furthermore, the rack and the base 100 are slidably engaged via a slide rail and a slider, which reduces the driving force required to move the second limiting member 420. In addition, the first gear 310 can serve as a rotary transmission component in the rotary drive assembly 300 or in the rotary-linear conversion assembly 200. By sharing components of the first gear 310, the structural complexity of the air spring assembly device can be further reduced.

[0074] In one or more embodiments, refer to Figure 1 and Figure 2 As shown, the air spring assembly device may further include a scale 500 disposed on the surface of the base 100, wherein the scale extension direction of the scale 500 is parallel to the linear movement direction of the second limiting member 420, so as to mark the reciprocating linear displacement of the second limiting member 420 by means of the scale 500.

[0075] In this embodiment, the linear displacement corresponding to the reciprocating linear motion of the second limiting member 420 can be visually estimated through the scale on the scale 500. Therefore, when the air spring 700 is determined to have compressed or extended to a preset length according to the scale 500, the operation of the rotary drive assembly 300 can be stopped, allowing the second limiting member 420 to maintain its current position. The scale 500 improves the control accuracy of the extension and retraction length of the air spring 700. The scale 500 can be attached to the upper surface of the base 100, and the extension direction of the scale of the scale 500 is parallel to the linear motion direction of the second limiting member 420. For example, the 0 mark of the scale 500 can correspond to the initial position of the second limiting member 420. When the operator rotates the rocker arm 330 to compress and curl the air spring 700, they can determine that the air spring 700 has reached the preset compression length based on the scale on the scale 500, and then stop the operation of the rocker arm 330. With the first gear 310 and the second gear 320 engaged, the air spring 700 maintains its current compressed state, and the curling process of the air spring 700 is completed. At this time, the air spring 700 can be removed from the limiting component 400 in the vertical direction.

[0076] In one or more embodiments, refer to Figure 1 and Figure 2As shown, the slider 220 extends to the upper surface of the base 100 and is positioned near the scale of the ruler 500. Alternatively, the air spring assembly device may further include a connecting member that is kinetically connected to the rack or the second limiting member 420, the connecting member extending to the upper surface of the base 100 and positioned near the scale of the ruler 500.

[0077] In this embodiment, the setting of the scale near the ruler 500 can include the following two situations: First, the slider 220 or the connector is in direct contact with the scale on the ruler 500. Second, the distance between the slider 220 or the connector and the scale on the ruler 500 is short. For example, the distance is within 1 cm or 2 cm. Considering that the longer the distance between the slider 220 / connector and the ruler 500, the greater the error in the reading of the ruler 500 obtained by the operator by visual inspection, setting the slider 220 or connector close to the scale on the ruler 500 can make it easier for the operator to accurately observe the reciprocating linear displacement of the second limiting member 420 and can improve the control accuracy of the extension and retraction length of the air spring 700.

[0078] In one or more embodiments, refer to Figure 1-6 As shown, the air spring assembly device may further include a protective cover 600, which is matched with the base 100 to form a telescopic space 601 for the air spring 700 to be embedded within. For example, the base 100 has an assembly groove, the protective cover 600 is inserted into the assembly groove, and the protective cover 600 can be snapped into the base 100. Alternatively, the base 100 is inserted into the assembly groove and then moves along the linear motion direction of the rotary linear conversion component 200, thereby forming a misaligned fit between the protective cover 600 and the base 100. The telescopic space 601 is completely penetrated along the linear direction of the second limiting member 420, and the protective cover 600 is positioned close to the first limiting member 410. That is, the protective cover 600 is located on the base 100 between the first limiting member 410 and the second limiting member 420. Figure 6 As shown, by enclosing the air spring 700 with the protective cover 600, the compressed air spring 700 is kept within the protective cover 600, which prevents the air spring 700 from breaking during compression due to product defects or other factors, thus avoiding the splashing of parts and improving the operational safety factor of the air spring assembly device.

[0079] In one or more embodiments, the first limiting member 410 is provided with a first limiting groove 411. The cross-sectional shape of the first limiting groove 411 is arc-shaped, and the arc shape is less than or equal to half an arc, so that the air spring 700 can be engaged with the groove wall of the first limiting groove 411. The provision of the first limiting groove 411 facilitates the direct placement of the air spring 700 into the first limiting member 410 in the vertical direction, and the engagement with the groove wall of the first limiting groove 411, thereby axially limiting the first end of the air spring 700. The first limiting groove 411 can improve the limiting accuracy of the air spring 700 and facilitate the improvement of the loading and unloading efficiency of the air spring 700.

[0080] In one or more embodiments, the second limiting member 420 is provided with a second limiting groove 421. The cross-sectional shape of the second limiting groove 421 is arc-shaped, and the arc shape is less than or equal to half an arc, so that the air spring 700 can be engaged with the groove wall of the second limiting groove 421. The provision of the second limiting groove 421 facilitates the direct placement of the air spring 700 vertically onto the second limiting member 420 and the engagement with the groove wall of the second limiting groove 421, thereby axially limiting the second end of the air spring 700. The second limiting groove 421 can improve the limiting accuracy of the air spring 700 and facilitate the improvement of the loading and unloading efficiency of the air spring 700.

[0081] In summary, this application discloses an air spring assembly device, which may include a base 100, a rotary-to-linear conversion component 200, a rotary drive component 300, and a limiting component 400. The base 100 has an assembly space 101, and the rotary-to-linear conversion component 200 is disposed in the assembly space 101 and rotates relative to the base 100. The rotary drive component 300 is drive-connected to the rotary-to-linear conversion component 200. The limiting component 400 includes a first limiting member 410 and a second limiting member 420, which are distributed opposite to each other along both ends of the linear conversion component. The first limiting member 410 and the second limiting member 420 are respectively used to limit and cooperate with both ends of the air spring 700. The first limiting member 410 is disposed on the base 100, and the second limiting member 420 is drive-connected to the linear output end of the rotary-to-linear conversion component 200. When the rotary drive assembly 300 inputs rotational motion to the rotary-linear conversion assembly 200, the rotary-linear conversion assembly 200 drives the second limiting member 420 to perform reciprocating linear motion, thereby causing the air spring 700 to perform telescopic motion, realizing the assembly and disassembly of the air spring 700. Thus, by the operation of the rotary drive assembly 300 driving the air spring 700 to perform compression motion, the air bladder in the air spring 700 flips to wrap around the piston. Alternatively, by the operation of the rotary drive assembly 300 driving the air spring 700 to perform extension motion, the air bladder separates from the piston, completing the disassembly of the air spring 700. This embodiment simplifies the structure of the air spring assembly device, and without the need for any drive source, the operator rotates the rocker arm 330, causing the rotary-linear conversion assembly 200 to drive the second limiting member 420 to perform reciprocating linear motion, thereby causing the air spring 700 to telescopic, thus greatly improving the ease of assembly and disassembly of the air spring 700.

[0082] Furthermore, the air spring assembly device can quickly assemble and disassemble the air spring using a purely mechanical structure, has a long service life, and can minimize the structural cost of the air spring assembly device.
