Description

Technical Field

[0001] This application relates to the field of disassembly technology, and more particularly to a tire disassembly device. Background Technology

[0002] In the field of automotive repair and maintenance, tire removal and installation is a high-frequency and critical operation, and its efficiency and safety directly affect the quality of repair services and the lifespan of tires and rims. Currently, the mainstream automotive tire removal and installation equipment in the industry mainly relies on two types of core structures to achieve tire removal and installation: one is a combination structure of traditional pry bar and tire lifter, and the other is a relatively complex pneumatic tire removal device.

[0003] The traditional method of using a pry bar and a tire lifter relies entirely on manual application of external force to separate or assemble the tire from the rim. This is not only time-consuming and labor-intensive, significantly increasing the workload of maintenance personnel, but also poses significant safety hazards. The manual force is difficult to control precisely, and the operator's hand is easily injured due to the pry bar slipping. At the same time, the hard-contact prying method can cause impact damage to the rim surface or scratch the tire bead, affecting the sealing performance of the tire and rim and the overall service life.

[0004] While existing pneumatic tire changers, by using pneumatic power to replace some manual operations and reduce labor costs to a certain extent, generally suffer from unreasonable structural design: some devices lack stable motion guidance mechanisms, making it easy for the tire changer components to deviate from their trajectory, resulting in unexpected contact with the wheel hub and tire during the removal and installation process, causing damage; some devices, in order to achieve complex motion functions, excessively increase structural complexity, which not only increases manufacturing costs and maintenance difficulty, but also reduces the overall stability of the equipment. After long-term use, components are prone to loosening, jamming, and other malfunctions, further affecting the removal and installation efficiency and safety factor.

[0005] However, the inventors have discovered at least the following technical problems in the relevant technology: the existing tire-removal components have unstable running trajectories and are prone to damaging the wheel rims and tires. Utility Model Content

[0006] One object of this application is to provide a tire removal device that at least solves the above-mentioned problems.

[0007] To achieve the above objectives, some embodiments of this application provide a tire removal device, including:

[0008] The mounting box is constructed with a first guide groove;

[0009] The tire removal hook body is slidably disposed in the first guide groove of the mounting box. The bottom end of the tire removal hook body is provided with a hook-shaped structure for hooking the tire. A sliding groove is opened on the tire removal hook body. The tire removal hook body is slidably connected to the first guide groove of the mounting box through a limiting pin. At least one end of the limiting pin is fixed to the side wall of the first guide groove, and the other end passes through the sliding groove and slides in cooperation with the sliding groove. Under the limiting action of the limiting pin and the sliding groove, the tire removal hook body can reciprocate along the extension direction of the first guide groove.

[0010] A connecting rod is located in the first guide groove. One end of the connecting rod is rotatably connected to the side wall of the first guide groove, and the other end is rotatably connected to the tire removal hook body. The connecting rod is used to constrain the movement trajectory of the tire removal hook body.

[0011] Compared with related technologies, the solution provided in this application's embodiments forms a complete "guiding-execution-constraint" motion system through the coordinated action of the mounting box, the tire removal hook body, and the connecting rod. The first guide groove of the mounting box provides basic guidance, the tire removal hook body achieves directional movement through the cooperation of the sliding groove and the limiting pin, and the connecting rod further constrains trajectory deviations. Together, these three components ensure the motion stability and hooking accuracy of the tire removal hook body, providing structural protection for efficient and safe tire removal and installation, and avoiding problems such as low removal and installation efficiency and easy damage to the wheel rim caused by disordered component movement in traditional removal and installation devices.

[0012] By constructing the first guide groove, a stable mounting and movement carrier is provided for the tire removal hook body and connecting rod, the assembly space boundary of each component is clearly defined, and the position disorder caused by the lack of a guide structure during component movement is avoided, ensuring the regularity of the overall structure of the device and the ease of assembly. At the same time, it lays the foundation for the directional movement of the tire removal hook body in the future.

[0013] The hook-shaped structure of the tire removal hook body can directly act on the tire rim to effectively hook the tire, providing a core execution component for tire removal and installation. The cooperation of the sliding groove and the limiting pin restricts the tire removal hook body to reciprocate only along the extension direction of the first guide groove, preventing disorderly deviation of its movement direction and ensuring that the hook-shaped structure is always aligned with the position to be hooked on the rim. The slidable setting allows the tire removal hook body to adjust its position according to the removal and installation requirements, adapting to the relative positional relationship between the tire and the rim under different working conditions, and improving the versatility of the device.

[0014] The connecting rod, through its own rigid constraint and the rotational cooperation at both ends, limits the tire removal hook body to reciprocate along the preset trajectory formed by the cooperation of the slide groove and the limit pin, so as to prevent the tire removal hook body from lateral swinging or twisting off the preset trajectory during the movement, and ensure that the hook-shaped structure at the bottom of the tire removal hook body is always accurately aligned with the position to be hooked on the tire rim.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0046] Combination Figures 1 to 11 As shown in the figure, a tire removal device provided in this embodiment includes: a mounting box 10, a tire removal hook body 20, and a connecting rod 40.

[0047] The mounting box 10 has a first guide groove 101. The tire removal hook body 20 is slidably disposed in the first guide groove 101 of the mounting box 10. The bottom end of the tire removal hook body 20 has a hook-shaped structure 201 for hooking the tire. The tire removal hook body 20 has a sliding groove 202. The tire removal hook body 20 is slidably connected to the first guide groove 101 of the mounting box 10 through a limiting pin 30. At least one end of the limiting pin 30 is fixed to the side wall of the first guide groove 101, and the other end passes through the sliding groove 202 and slides in cooperation with the sliding groove 202. Under the limiting action of the limiting pin 30 and the sliding groove 202, the tire removal hook body 20 can reciprocate along the extension direction of the first guide groove 101. The connecting rod 40 is disposed in the first guide groove 101. One end of the connecting rod 40 is rotatably connected to the side wall of the first guide groove 101, and the other end is rotatably connected to the tire removal hook body 20. The connecting rod 40 is used to constrain the movement trajectory of the tire removal hook body 20.

[0048] The tire removal device provided in this embodiment forms a complete motion system of "guidance-execution-constraint" through the coordinated action of the mounting box 10, the tire removal hook body 20, and the connecting rod 40. The first guide groove 101 of the mounting box 10 provides basic guidance, the tire removal hook body 20 achieves directional movement through the cooperation of the sliding groove 202 and the limiting pin 30, and the connecting rod 40 further constrains the trajectory deviation. The three together ensure the motion stability and hooking accuracy of the tire removal hook body 20, providing structural protection for efficient and safe tire removal and installation, and avoiding problems such as low removal and installation efficiency and easy damage to the wheel rim caused by disordered movement of components in traditional removal and installation devices.

[0049] By constructing the first guide groove 101, a stable mounting and movement carrier is provided for the tire removal hook body 20 and the connecting rod 40, the assembly space boundary of each component is clearly defined, and the position disorder caused by the lack of a guide structure during component movement is avoided, ensuring the regularity of the overall structure of the device and the ease of assembly. At the same time, it lays the foundation for the directional movement of the tire removal hook body 20.

[0050] The hook-shaped structure 201 of the tire removal hook body 20 can directly act on the tire rim to effectively hook the tire, providing a core execution component for tire removal and installation. The sliding groove 202 and the limiting pin 30 cooperate to limit the tire removal hook body 20 to move back and forth only along the extension direction of the first guide groove 101, avoiding disorderly deviation of its movement direction and ensuring that the hook-shaped structure 201 can always be aligned with the position to be hooked on the rim. The slidable setting allows the tire removal hook body 20 to adjust its position according to the removal and installation requirements, adapting to the relative positional relationship between the tire and the rim under different working conditions, and improving the versatility of the device.

[0051] The connecting rod 40, through its own rigid constraint and the rotational cooperation at both ends, limits the tire removal hook body 20 to reciprocate along the preset trajectory formed by the cooperation of the slide groove 202 and the limit pin 30, so as to prevent the tire removal hook body 20 from deviating from the preset trajectory during the movement, and ensure that the hook-shaped structure 201 at the bottom of the tire removal hook body 20 is always accurately aligned with the position to be hooked on the tire rim.

[0052] Optionally, the tire removal hook body 20 has a receiving groove 203 constructed below the sliding groove 202 along the extension direction of the sliding groove 202. The first end of the connecting rod 40 is rotatably connected to the side wall of the first guide groove 101 through the first mounting shaft 50, and the second end of the connecting rod 40 is inserted into the receiving groove 203 and rotatably connected to the side wall of the receiving groove 203.

[0053] The receiving groove 203 provides installation space for the second end of the connecting rod 40. The second end of the connecting rod 40 is inserted into it and rotatably connected to the side wall of the receiving groove 203, making the connection between the connecting rod 40 and the tire removal hook body 20 more compact and reducing the overall space occupied by the device.

[0054] The axis of the first mounting shaft 50 is perpendicular to the extension direction of the first guide groove 101, and the two ends of the first mounting shaft 50 are respectively detachably fixed to the two side walls opposite to the first guide groove 101 (such as interference fit, snap ring limit).

[0055] The second end of the connecting rod 40 is inserted into the cavity of the receiving groove 203, and the second end of the connecting rod 40 forms a rotatable connection with the two side walls of the receiving groove 203. The axis of the rotatable connection is parallel to the axis of the first mounting shaft 50, ensuring that the connecting rod 40 can only rotate around the axis parallel to the first mounting shaft 50, thereby forming a stable unilateral constraint on the movement trajectory of the tire removal hook body 20 and preventing the tire removal hook body 20 from lateral deviation during reciprocating motion.

[0056] Optionally, the second end of the connecting rod 40 is rotatably connected to the side wall of the receiving groove 203 in any of the following ways:

[0057] The second end of the connecting rod 40 has a boss, and the inner wall of the receiving groove 203 has a matching groove. The boss is embedded in the groove and can rotate.

[0058] The second end of the connecting rod 40 can be rotatably connected to the side wall of the receiving groove 203 through the second mounting shaft 60, that is, the second mounting shaft 60 passes through the connecting rod 40 and the side wall of the receiving groove 203;

[0059] The receiving groove 203 is a through structure, and the tire removal hook body 20 is provided with a through hole 208 corresponding to the position of the receiving groove 203. The second end of the connecting rod 40 is embedded in the receiving groove 203 and is provided with a corresponding through hole. The second mounting shaft 60 passes through the through hole 208 and is rotatably connected to the second end of the connecting rod 40; or the boss of the second end of the connecting rod 40 is embedded in the through hole 208 to achieve a rotatable connection.

[0060] The second end boss of the connecting rod 40 is embedded in the groove of the receiving slot 203 and rotates. The structure is simple and does not require additional connecting parts 702, reducing the number of parts and the assembly complexity. At the same time, the cooperation between the boss and the groove can achieve precise positioning and ensure smooth rotation.

[0061] The second end of the connecting rod 40 is rotatably connected to the side wall of the receiving groove 203 via the second mounting shaft 60, or rotatably connected to the second end of the connecting rod 40 via the second mounting shaft 60 passing through the through hole 208. Both methods can achieve stable rotational engagement, have high connection strength, and can withstand large forces, preventing the connecting rod 40 and the tire hook body 20 from becoming loose or detached during movement, thus ensuring the trajectory constraint effect.

[0062] Optionally, the connecting rod 40 is a rigid straight rod structure. The axis of the straight rod structure remains within the motion plane of the tire-removing hook body 20 during movement, and the rod body has no bending or irregular protrusions. Through the rigid transmission characteristics of the straight rod structure, the trajectory constraint of the connecting rod 40 on the tire-removing hook body 20 is ensured to be a linear and controllable constraint, avoiding constraint lag or trajectory deviation caused by the irregular shape of the connecting rod 40 itself. At the same time, the straight rod structure is easy to process and manufacture and has a lower cost, which can improve the overall production economy and assembly convenience of the device.

[0063] Optionally, the connecting rod 40 is a straight rod structure with a circular, rectangular, or polygonal cross-section. The length of the straight rod structure is adapted to the depth of the first guide groove 101 and the travel of the tire hook body 20. Both ends of the straight rod structure are respectively constructed with connecting parts for cooperating with the first mounting shaft 50 and the receiving groove 203. The connecting part at the first end of the straight rod structure is a through hole, the diameter of which is adapted to the outer diameter of the first mounting shaft 50, allowing the first mounting shaft 50 to pass through to realize the rotational connection between the connecting rod 40 and the side wall of the first guide groove 101. The connecting part at the second end of the straight rod structure is a plane, a boss, or a through hole, respectively adapted to fit and rotate with the groove on the inner side wall of the receiving groove 203, and to rotate by passing through the second mounting shaft 60 on the side wall of the receiving groove 203.

[0064] Optionally, the receiving groove 203 is located on the center line of the tire removal hook body 20 along the depth direction of the slide groove 202 (that is, the central axis of the receiving groove 203 is collinear with the central axis of the tire removal hook body 20 along the depth direction of the slide groove 202), and the receiving groove 203 has a symmetrical structure on the center line.

[0065] By ensuring that the center lines of the receiving grooves 203 are collinear and symmetrically arranged, the rotational connection point between the connecting rod 40 and the tire removal hook body 20 is located in the force center area of ​​the tire removal hook body 20. This ensures that when the tire removal hook body 20 moves, the constraint reaction force applied by the connecting rod 40 can be evenly transmitted to the entire tire removal hook body 20, avoiding unilateral wear or movement jamming of the tire removal hook body 20 due to force deviation. At the same time, it ensures that the hook structure 201 always moves accurately along the preset trajectory, improving the stability and service life of the device for tire removal and installation.

[0066] Optionally, the slide groove 202 can be a blind groove structure or a through structure; when the slide groove 202 is a blind groove structure, the opening direction of the slide groove 202 faces the side wall of the first guide groove 101 on which the limiting pin 30 is installed; when the slide groove 202 is a through structure, one end of the limiting pin 30 is installed on the side wall of the first guide groove 101, and the other end of the limiting pin 30 is suspended through the slide groove 202, or the other end of the limiting pin 30 passes through the slide groove 202 and is fixed to the other side wall of the first guide groove 101.

[0067] The opening of the slide groove 202 faces the side wall of the first guide groove 101 on which the limit pin 30 is installed. This reduces the entry of external dust and impurities into the slide groove 202, reduces wear between the limit pin 30 and the slide groove 202, and ensures smooth sliding cooperation between the two. At the same time, the blind groove structure can provide a certain degree of shielding and protection for the limit pin 30, and extend the service life of the component.

[0068] One end of the limiting pin 30 is installed on the side wall of the first guide groove 101, and the other end is suspended or fixed to the other side wall through the sliding groove 202. Both settings can enhance the limiting effect of the limiting pin 30 on the tire removal hook body 20, prevent the tire removal hook body 20 from tilting to one side during movement, and ensure that the tire removal hook body 20 moves smoothly along the preset trajectory. In addition, the through structure facilitates the maintenance and inspection of the limiting pin 30 and the sliding groove 202, and timely detection of component wear.

[0069] Optionally, the hook-shaped structure 201 at the bottom end of the tire hook body 20 is at least partially adapted to the contour of the wheel rim.

[0070] The hook-shaped structure 201 at the bottom of the tire hook body 20 has an arc-shaped hook surface that is adapted to the outer circumferential contour of the wheel rim. The difference between the radius of curvature of the arc-shaped hook surface and the outer circumferential radius of curvature of the target adapted wheel rim does not exceed a preset threshold, and the circumferential length of the arc-shaped hook surface is not less than the thickness of the wheel rim edge.

[0071] The hook tip of the hook structure 201 is rounded, and a smooth curved surface is formed at the transition between the hook tip and the arc hook surface. A limiting boss for fitting the inner wall of the wheel rim is constructed on the side of the arc hook surface away from the hook tip. The limiting boss is arranged along the extension direction of the arc hook surface, and the fitting surface of the limiting boss is adapted to the contour of the inner wall of the wheel rim.

[0072] By partially fitting the arc-shaped hook surface to the outer periphery of the wheel rim and fitting the limiting boss to the inner wall of the wheel rim, the hook-shaped structure 201 can form multi-point contact positioning with the wheel rim during the process of hooking the tire, thus avoiding slippage of the hook-shaped structure 201 relative to the wheel rim and reducing the risk of compression damage to the wheel rim surface caused by the hook-shaped structure 201.

[0073] Optionally, the slide groove 202 of the tire removal hook body 20 is arc-shaped, and the slide groove 202 includes a first limiting end 2021 and a second limiting end 2022; under the drive of the drive assembly, the tire removal hook body 20 slides relative to the limiting pin 30 through the slide groove 202; when the limiting pin 30 abuts against the first limiting end 2021 of the slide groove 202, the tire removal hook body 20 is in the locked position of hooking the tire; when the limiting pin 30 abuts against the second limiting end 2022 of the slide groove 202, the tire removal hook body 20 is in the extraction position.

[0074] The slide groove 202 of the tire removal hook body 20 has an arc-shaped structure with a preset curvature. The two ends of the arc-shaped slide groove 202 form a first limiting end 2021 and a second limiting end 2022, respectively, and the first limiting end 2021 and the second limiting end 2022 are spaced apart along the movement direction of the tire removal hook body 20. Under the driving force output by the drive component and the trajectory constraint of the connecting rod 40, the tire removal hook body 20 can drive the limiting pin 30, which is relatively fixed in the arc-shaped slide groove 202, to slide.

[0075] When the limiting pin 30 slides along the arc-shaped groove 202 to abut against the first limiting end 2021, the limiting pin 30 restricts the tire removal hook body 20 from continuing to move towards the tire rim through the first limiting end 2021. At this time, the hook-shaped structure 201 at the bottom of the tire removal hook body 20 is fully embedded in the preset hooking position of the tire rim, and the tire removal hook body 20 is in the fastening position of hooking the tire.

[0076] When the limiting pin 30 slides along the arc-shaped groove 202 to abut against the second limiting end 2022, the limiting pin 30 restricts the tire removal hook body 20 from continuing to move away from the tire rim through the second limiting end 2022. At this time, the hook-shaped structure 201 at the bottom of the tire removal hook body 20 has driven the tire edge to detach from the tire rim, and the tire removal hook body 20 is in the extraction position.

[0077] Under the driving force of the drive component and the trajectory constraint of the connecting rod 40, the tire removal hook body 20 drives the arc-shaped slide groove 202 to slide relative to the limit pin 30. The switching between the two position states ensures that the tire removal and installation process is carried out in an orderly manner, avoiding removal and installation failure or component damage caused by loss of control of the movement stroke, and ensuring that the tire removal and installation work is completed stably and efficiently.

[0078] Optionally, the tire hook body 20 includes at least a first part 204 and a second part 205 that are integrally formed or detachably fixedly connected. The first part 204 has a groove 202 on its side for the limiting pin 30 to pass through and slide. The second part 205 bends and extends from the bottom end of the first part 204 toward the center of the arc-shaped groove 202, and the free end of the second part 205 is constructed with a hook-shaped structure 201 for hooking the tire. The first part 204 and the second part 205 are bent at a preset angle, and the bending position forms a smoothly transitioned bending portion 206. The rotatable connection between the connecting rod 40 and the tire hook body 20 is located at the bending portion 206, or in the area of ​​the first part 204 near the bending portion 206, and the axis of the rotatable connection is perpendicular to the plane of motion of the tire hook body 20.

[0079] The direction in which the second part 205 bends toward the center of the arc-shaped groove 202 is opposite to the direction of the hook-holding opening of the hook-shaped structure 201. When the tire removal hook body 20 moves toward the fastening position along the arc-shaped groove 202, the bending direction of the second part 205 can guide the hook-shaped structure 201 to gradually approach from the outside to the inside of the tire rim. The reverse-set hook-holding opening can naturally face the inside edge of the rim when the hook-shaped structure 201 is close to the rim, ensuring that the hook-shaped structure 201 can accurately fit into the gap between the rim and the tire. When the tire removal hook body 20 moves toward the extraction position, the reverse-set hook-holding opening can firmly hook the edge of the rim, forming a stable force support in conjunction with the bending angle of the second part 205, preventing the hook-shaped structure 201 from detaching from the rim during the lifting process, and ensuring the reliability of the tire removal and installation operation.

[0080] The initial stationary position of the tire removal hook body 20 is defined as the extraction position. When the driving device 70 is a cylinder, the cylinder's extension rod extends along the second guide groove 102, driving the tire removal hook body 20 to move downwards along the preset trajectory of the arc-shaped slide groove 202. During this process, the connecting rod 40 forms a lateral constraint on the tire removal hook body 20, causing the hook-shaped structure 201 at the bottom of the tire removal hook body 20 to simultaneously displace towards the center of the tire, i.e., the hook-shaped structure 201 exhibits a "downward and inward" composite motion trajectory. This composite motion guides the hook-shaped structure 201 to gradually approach the tire rim and precisely insert into the gap between the rim and the tire until the limiting pin 30 abuts against the first limiting end 2021 of the arc-shaped slide groove 202. At this point, the tire removal hook body 20 stops moving and is in the latching position, and the hook-shaped structure 201 completely hooks the preset force-bearing part of the rim. (Reference) Figure 8 and Figure 11 As shown.

[0081] The cylinder extension rod extends and drives, combined with the lateral constraint of the connecting rod 40, causing the hook structure 201 to have a "downward and inward" compound motion trajectory. This guides the hook structure 201 to gradually approach the wheel rim and accurately insert into the gap between the wheel rim and the tire until it is in the locked position. This ensures that the hook structure 201 fully hooks the preset force-bearing part of the wheel rim, laying the foundation for subsequent tire removal. This compound motion trajectory makes the hooking process more stable and precise, avoiding collisions between the hook structure 201 and the wheel rim.

[0082] When the tire removal hook body 20 is in the locked position, the cylinder's telescopic rod retracts along the second guide groove 102, driving the tire removal hook body 20 to move along the preset trajectory of the arc-shaped slide groove 202 towards the top of the first guide groove 101. During this process, the connecting rod 40 continuously constrains the trajectory of the tire removal hook body 20, causing the hook-shaped structure 201 at the bottom of the tire removal hook body 20 to simultaneously displace away from the center of the tire, i.e., the hook-shaped structure 201 exhibits a composite motion trajectory of "upward and outward". This composite motion can drive the hook-shaped structure 201 to lift the rim, causing the tire edge to gradually detach from the rim until the limiting pin 30 abuts against the second limiting end 2022 of the arc-shaped slide groove 202. At this point, the tire removal hook body 20 returns to the extraction position, completing the tire extraction action from the rim. (Reference) Figure 7 and Figure 10 As shown.

[0083] The cylinder telescopic rod retracts, and the connecting rod 40 continuously constrains the trajectory. The hook-shaped structure 201 exhibits an "upward and outward" compound motion trajectory, which can drive the hook-shaped structure 201 to lift the wheel rim, causing the tire edge to gradually detach from the wheel rim until it returns to the extraction position, completing the tire extraction action. The compound motion trajectory can evenly apply the lifting force, avoiding damage to the wheel rim or tire due to uneven force, while ensuring that the tire stably detaches from the wheel rim, improving the reliability and safety of the extraction action.

[0084] Optionally, it also includes: a drive assembly, including a drive device 70 and a drive rod 80 that is telescopically extendable along the extension direction of the first guide groove 101, the free end of the drive rod 80 being rotatably connected to the top end of the tire removal hook body 20; wherein, the drive device 70 drives the drive rod 80 to telescopically move, and under the drive of the drive rod 80 and the constraint of the connecting rod 40, the tire removal hook body 20 reciprocates along a preset trajectory defined by the sliding groove 202 and the limiting pin 30.

[0085] The fixed end of the drive rod 80 is connected to the power output end of the drive device 70. The free end of the drive rod 80 is rotatably engaged with the top end of the tire removal hook body 20 via a rotatable connection structure (such as a transmission connection shaft 90), and the axis of this rotatable engagement is perpendicular to the plane of motion of the tire removal hook body 20. The drive device 70 is a power component (such as a cylinder or electric push rod) capable of outputting linear driving force. The drive device 70 is fixed at a preset position in the mounting box 10, and the power output direction of the drive device 70 is consistent with the extension direction of the first guide groove 101.

[0086] During operation, the drive unit 70 drives the drive rod 80 to extend and retract axially. The drive rod 80 transmits axial driving force to the tire removal hook body 20 through the rotational connection structure at its free end. During this process, the connecting rod 40 forms a trajectory constraint on the tire removal hook body 20. The two work together to ensure that the tire removal hook body 20 can only reciprocate along the preset trajectory defined by the sliding groove 202 and the limiting pin 30, ensuring that the driving force is always transmitted along the preset trajectory direction and preventing the tire removal hook body 20 from jamming or deviating from the trajectory due to deviation in the direction of force.

[0087] The drive unit 70 drives the drive rod 80 to extend and retract, and combined with the linkage 40 to constrain the trajectory of the tire removal hook body 20, the tire removal hook body 20 moves stably back and forth along the preset trajectory, without the need for manual driving, realizing the mechanization of tire removal and installation, reducing the intensity of manual labor, while ensuring stable transmission of driving force, avoiding the movement deviation of the tire removal hook body 20 caused by uneven manual operation force, and improving work efficiency and stability.

[0088] Optionally, the free end of the drive rod 80 is rotatably connected to the top end of the tire removal hook body 20 via a transmission connecting shaft 90, and the transmission connecting shaft 90 is respectively perpendicular to the drive rod 80 and the tire removal hook body 20.

[0089] The transmission connecting shaft 90 is a cylindrical rod-shaped structure. Its axis is perpendicular to the axis of the drive rod 80 and the motion plane of the tire removal hook body 20. That is, the axis of the transmission connecting shaft 90 is perpendicular to both the extension and retraction direction of the drive rod 80 and the plane in which the tire removal hook body 20 moves back and forth along a preset trajectory.

[0090] The first end of the transmission connecting shaft 90 is detachably and fixedly connected to the free end of the drive rod 80 (such as threaded connection or interference fit). The second end of the transmission connecting shaft 90 passes through the pre-set through hole 207 at the top of the tire removal hook body 20 and forms a clearance fit with the hole wall of the through hole 207 to ensure that the transmission connecting shaft 90 can rotate flexibly relative to the tire removal hook body 20, while avoiding radial shaking between the transmission connecting shaft 90 and the tire removal hook body 20 due to excessive clearance.

[0091] By vertically connecting the transmission shaft 90 to the drive rod 80 and the tire removal hook body 20, the axial driving force output by the drive rod 80 can be smoothly transmitted in a direction perpendicular to the plane of motion of the tire removal hook body 20. When the tire removal hook body 20 moves along a preset trajectory, the transmission shaft 90 can adapt to the angle change between the drive rod 80 and the tire removal hook body 20 by rotating itself, ensuring that the movements of the two do not interfere with each other and guaranteeing the continuity and stability of the driving force transmission.

[0092] Optionally, the free end of the drive rod 80 is provided with a threaded structure 801, and the first end of the transmission connecting shaft 90 is provided with a through hole. The free end of the drive rod 80 passes through the through hole and is threadedly connected by a nut to achieve a fixed connection between the drive rod 80 and the transmission connecting shaft 90; or, the first end of the transmission connecting shaft 90 is provided with a threaded hole 901, and the threaded structure 801 of the free end of the drive rod 80 is connected to the threaded hole 901 of the transmission connecting shaft 90 to achieve a fixed connection between the drive rod 80 and the transmission connecting shaft 90; or, the free end of the drive rod 80 is provided with a threaded structure 801, and the first end of the transmission connecting shaft 90 is provided with a threaded hole 901, and the threaded structure 801 of the free end of the drive rod 80 is connected to the threaded hole 901 of the transmission connecting shaft 90 to achieve a fixed connection between the drive rod 80 and the transmission connecting shaft 90; or, when the free end of the drive rod 80 is threadedly connected to the threaded hole 901 of the first end of the transmission connecting shaft 90, the free end of the drive rod 80 can extend out of the transmission connecting shaft 90 and be further fixed by a nut.

[0093] The free end of the drive rod 80 passes through the through hole of the transmission connecting shaft 90 and is fixed by a nut, or the free end of the drive rod 80 is connected to the threaded hole 901 of the transmission connecting shaft 90. Both threaded connection methods can achieve detachable and secure fixation of the two, which is convenient for assembly and later maintenance and replacement. At the same time, the relative position of the two can be finely adjusted by adjusting the nut or the thread mating depth to ensure assembly accuracy.

[0094] In addition, the free end of the drive rod 80 extends out of the transmission connecting shaft 90 and is further fixed by a nut. Compared with a single threaded connection, this increases the number of fixing points, improves the stability and reliability of the connection, effectively resists the vibration generated during the operation of the device, prevents loosening between the drive rod 80 and the transmission connecting shaft 90, and ensures stable transmission of driving force.

[0095] Optionally, the first end of the transmission connecting shaft 90 is provided with at least a first positioning plane 902, and the transmission connecting shaft 90 abuts against the shoulder of the drive rod 80 through the first positioning plane 902.

[0096] The first end of the transmission connecting shaft 90 is radially cut to form at least one first positioning plane 902. The first positioning plane 902 is a planar structure and is parallel to the axis of the transmission connecting shaft 90. The end of the drive rod 80 near the transmission connecting shaft 90 is constructed with an annular shoulder. When the first end of the transmission connecting shaft 90 is assembled with the drive rod 80, the first positioning plane 902 and the end face of the annular shoulder of the drive rod 80 are tightly abutted to form circumferential positioning, which restricts the relative rotation between the transmission connecting shaft 90 and the drive rod 80 and ensures that the two move synchronously along the axial direction of the drive rod 80.

[0097] Optionally, the first end of the transmission connecting shaft 90 may also be provided with a second positioning plane 903, which is symmetrically arranged with the first positioning plane 902 so that when the free end of the drive rod 80 is threadedly connected to the nut, the nut abuts against the second positioning plane 903.

[0098] The first end of the transmission connecting shaft 90 can also be radially cut to form a second positioning plane 903. The second positioning plane 903 and the first positioning plane 902 are symmetrically arranged about the axis of the transmission connecting shaft 90, and the second positioning plane 903 and the first positioning plane 902 have the same size and shape. When the free end of the drive rod 80 is fixed to the transmission connecting shaft 90 by a nut thread connection, the end face of the nut abuts tightly against the second positioning plane 903. The second positioning plane 903 forms a circumferential limit on the nut, preventing the nut from rotating and loosening due to vibration during the operation of the device, while ensuring that the axial preload of the nut on the drive rod 80 and the transmission connecting shaft 90 is evenly transmitted.

[0099] Optionally, the outer peripheral surface of the transmission connecting shaft 90 is provided with a shoulder 904. When the second end of the transmission connecting shaft 90 passes through the top of the tire removal hook body 20, the tire removal hook body 20 abuts against the shoulder 904 of the transmission connecting shaft 90, and a stop 100 is provided at the second end of the transmission connecting shaft 90 to prevent the transmission connecting shaft 90 from separating from the tire removal hook body 20.

[0100] The outer circumferential surface of the transmission connecting shaft 90 is integrally formed with an annular shoulder 904. The axis of the annular shoulder is collinear with the axis of the transmission connecting shaft 90, and the outer diameter of the annular shoulder 904 is larger than the diameter of the through hole 207 at the top of the tire removal hook body 20 of the transmission connecting shaft 90. After the second end of the transmission connecting shaft 90 passes through the pre-set through hole 207 at the top of the tire removal hook body 20 in sequence along the axial direction, the end face of the annular shoulder 904 abuts against the outer wall of the tire removal hook body 20, forming an axial limit and restricting the transmission connecting shaft 90 from moving away from the tire removal hook body 20. The direction of movement; a stop 100 is provided at the second end of the transmission connecting shaft 90 and on the side of the tire removal hook body 20 away from the shoulder 904. The stop 100 is detachably fixed to the transmission connecting shaft 90. Through the bidirectional clamping action of the stop 100 and the annular shoulder 904, the transmission connecting shaft 90 and the tire removal hook body 20 are limited to the preset assembly position to prevent the two from separating along the axial direction of the transmission connecting shaft 90, while not affecting the relative rotation of the transmission connecting shaft 90 and the tire removal hook body 20 around the axis of the through hole 207.

[0101] Optionally, the stop 100 can be a nut, a pin, or a cotter pin. When the stop 100 is a nut, it is threaded to the thread structure 801 at the second end of the transmission connecting shaft 90. When the stop 100 is a pin, the second end of the transmission connecting shaft 90 has a hole, and the pin is inserted into the hole to fix it. When the stop 100 is a cotter pin, it is inserted into the hole to achieve relative fixation between the stop 100 and the transmission connecting shaft 90, and to prevent the transmission connecting shaft 90 from separating from the tire-removing hook body 20.

[0102] Optionally, the second end of the transmission connecting shaft 90 is constructed with a limiting groove 905, and the stop 100 is embedded in the limiting groove 905 to achieve relative fixation between the stop 100 and the transmission connecting shaft 90, and to prevent the transmission connecting shaft 90 from separating from the tire removal hook body 20.

[0103] When the stop 100 is a nut, it is fixed to the second end of the transmission connecting shaft 90 via a threaded connection. The connection is firm and easy to disassemble. The position of the nut can be adjusted according to actual needs to adapt to different assembly scenarios. When the stop 100 is a pin, it is inserted into the insertion hole of the transmission connecting shaft 90 for fixation. Installation is convenient, and it can quickly achieve the stopping function. It also has a simple structure and low cost. When the stop 100 is a cotter pin, it is inserted into the insertion hole. It not only achieves the stopping function and prevents the transmission connecting shaft 90 from separating from the tire-removing hook body 20, but also has the characteristics of easy installation and disassembly, and is not easy to loosen. It can maintain a stable stopping effect in a vibration environment.

[0104] Optionally, the transmission connecting shaft 90 and the drive rod 80 move synchronously along the axial direction of the drive rod 80, and the transmission connecting shaft 90 is rotatably connected to the tire removal hook body 20.

[0105] The transmission connecting shaft 90 and the drive rod 80 move synchronously along the axial direction of the drive rod 80, ensuring that the driving force is efficiently transmitted from the drive rod 80 to the transmission connecting shaft 90. At the same time, the transmission connecting shaft 90 is rotatably connected to the tire removal hook body 20, which can adapt to the angle changes of the tire removal hook body 20 during the movement process, avoid motion interference between the two, ensure that the tire removal hook body 20 moves smoothly along the preset trajectory, and further improve the continuity and stability of the driving force transmission.

[0106] Optionally, the mounting box 10 is also configured with a second guide groove 102 arranged parallel to the first guide groove 101, and the drive rod 80 is disposed in the second guide groove 102 and moves telescopically along the extension direction of the second guide groove 102.

[0107] The second guide groove 102 is parallel to the first guide groove 101. The drive rod 80 is located in it and extends and retracts along its extension direction, providing a dedicated movement channel for the drive rod 80, clarifying the movement direction of the drive rod 80, avoiding deviation of the drive rod 80 during extension and retraction, and making the movement space of the drive rod 80 and the tire hook body 20 independent and parallel to each other, optimizing the internal structural layout of the device and reducing movement interference between components.

[0108] Optionally, the first guide groove 101 and the second guide groove 102 are adjacent and share the same vertical sidewall; the extension direction of the shared sidewall 103 is consistent with the extension direction of the first guide groove 101 and the second guide groove 102; the shared sidewall 103 is recessed at the transition position from the bottom region of the first guide groove 101 to the top region of the second guide groove 102 to avoid the transmission connecting shaft 90, so as to prevent the shared sidewall 103 from interfering with the transmission connecting shaft 90.

[0109] Specifically, at the bend where the common sidewall 103 transitions from the bottom region of the first guide groove 101 to the top region of the second guide groove 102, a recess is formed on the side away from the movement path of the transmission connecting shaft 90, forming a clearance recess 104. The depth of the clearance recess 104 is not less than the radius of the transmission connecting shaft 90, and the circumferential length of the clearance recess 104 is not less than the maximum movement distance of the transmission connecting shaft 90 in the transition region. By setting the clearance recess 104, sufficient movement space is provided for the transmission connecting shaft 90 when it extends and retracts with the drive rod 80 and swings with the tire removal hook body 20, effectively avoiding hard collisions or frictional interference between the transmission connecting shaft 90 and the common sidewall 103, ensuring the smooth movement of the transmission connecting shaft 90, and thus ensuring the stable transmission of the driving force of the drive rod 80 to the tire removal hook body 20.

[0110] Optionally, the drive device 70 is a cylinder, which is detachably connected to the top side wall of the second guide groove 102, facilitating the installation, disassembly, maintenance and replacement of the cylinder. At the same time, the fixed installation position ensures the stability of the cylinder during operation and prevents the extension and retraction direction of the drive rod 80 from changing due to cylinder position displacement.

[0111] Optionally, the cylinder is provided with a lug 701, which is rotatably connected to the side wall of the second guide groove 102 via a connector 702. The cylinder can rotate around the axis of the connector 702, thereby driving the drive rod 80 to synchronously adjust the extension and retraction direction to adapt to the dynamic angle change when the tire hook body 20 moves back and forth along a preset trajectory.

[0112] The cylinder body has an integrally formed or detachably fixed lug 701 on its outer side wall. The lug 701 has a mounting hole 7011 through it along the direction perpendicular to the cylinder's extension and retraction. The top side wall of the second guide groove 102 has two oppositely arranged connecting ear plates protruding from it at the position of the lug 701. Both connecting ear plates have an assembly hole 105 coaxial with the mounting hole 7011. The connector 702 is a pin or bolt. The connector 702 passes through the assembly hole 105 of the connecting ear plate and the mounting hole 7011 of the lug 701 in sequence. The connector 702 is rotatably fitted with the lug 701 and the connecting ear plate.

[0113] By rotating the lug 701 with the connecting lug plate (which can also be understood as the side wall of the second guide groove 102), the cylinder can rotate around the axis of the connecting piece 702, thereby driving the drive rod 80 to synchronously adjust the extension and retraction direction to adapt to the dynamic angle change when the tire hook body 20 moves back and forth along the preset trajectory, ensuring that the driving force of the drive rod 80 on the tire hook body 20 is always transmitted in the effective work direction, avoiding additional stress or movement interference caused by the misalignment of the two movement directions.

[0114] Optionally, it also includes: a mounting body 110, located at the bottom of the mounting box 10, for fixing the mounting box 10; wherein, the top end face of the mounting body 110 is provided with a through portion along the reciprocating motion direction of the tire removal hook body 20, the through portion corresponds to and communicates with the opening area at the bottom of the mounting box 10, together forming an avoidance portion 1101 for the reciprocating motion of the tire removal hook body 20.

[0115] The mounting body 110 is located at the bottom of the mounting box 10, providing a stable mounting base for the entire device and ensuring that the device does not shift position during operation. The top end face through part and the bottom opening area of ​​the mounting box 10 form a clearance part 1101, providing sufficient space for the reciprocating movement of the tire removal hook body 20, avoiding collision between the tire removal hook body 20 and the mounting body 110 during movement, and ensuring smooth movement.

[0116] Optionally, the width of the clearance portion 1101 is not less than the maximum lateral offset of the tire hook body 20 during the movement, and a gap is reserved between the inner wall of the clearance portion 1101 and the outer wall of the tire hook body 20 to ensure that the tire hook body 20 moves back and forth along the preset trajectory without jamming or collision, while avoiding deviation of the movement trajectory of the tire hook body 20 due to excessive gap.

[0117] Optionally, the mounting body 110 is a plate-shaped or frame-type structure, and the mounting body 110 is detachably and fixedly connected to the bottom of the mounting box 10 (such as bolt connection or snap-fit ​​connection). The mounting body 110 is used to fix the mounting box 10 to an external work platform or equipment frame.

[0118] Optionally, it also includes: a steel column 120, which is inserted into the top of the mounting body 110 to help fix the relative position of the mounting body 110 and the external mounting structure, prevent the mounting body 110 from rotating or shifting relative to the external mounting structure during operation, further improve the overall stability of the device installation, ensure that the device is always in the preset working position during operation, and ensure the accuracy and reliability of tire removal and installation. At the same time, the steel column 120 can be a hexagonal structure, which is convenient for tool clamping and facilitates the insertion and adjustment of the hexagonal steel column 120.
