[0056] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] At present, the tires used in low-speed electric vehicles mainly include pneumatic tires (also known as inflated tires) and solid tires. Among them, solid tires have the advantages of not requiring inflation and having no risk of blowouts, and are increasingly widely used in low-speed electric vehicles.

[0058] An embodiment of the present invention provides a tire mounting machine. Refer to Figure 1 as shown, including:

[0059] An operating table 1;

[0060] A turntable mechanism 2, arranged on the operating table 1, for detachably connecting with the wheel hub and driving the wheel hub to rotate;

[0061] A mounting frame 3, arranged on the operating table 1, having a cross beam 31 located above the turntable mechanism 2;

[0062] A tire pressing assembly 4, arranged between the cross beam 31 and the operating table 1;

[0063] An axis limiting assembly 5, arranged between the cross beam 31 and the operating table 1, for detachably connecting the wheel hub to the turntable mechanism 2 and restricting the axis line of the wheel hub to be collinear with the rotation axis line of the turntable mechanism 2 when the wheel hub rotates.

[0064] When a tire mounting operation needs to be performed, the user can place the wheel hub at the tire mounting position of the turntable mechanism 2 for connecting the wheel hub, and operate the axis limiting assembly 5 to detachably connect the wheel hub to the turntable mechanism 2. During the process of achieving the detachable connection, synchronously, the axis limiting assembly 5 also restricts the axis line of the wheel hub to be collinear with the rotation axis line of the turntable mechanism 2. Further, the user operates the turntable mechanism 2 to rotate, driving the wheel hub connected to the turntable mechanism 2 to rotate around the axis line of the wheel hub itself. During the rotation process, the user can operate the tire pressing assembly 4 to squeeze the tire and gradually press the tire into the wheel hub. When the tire is completely pressed into the wheel hub, the tire mounting operation is completed. At this time, the user can operate the turntable mechanism 2 to stop rotating.

[0065] In an embodiment of the present invention, the tire mounting machine includes: an operating table 1; a turntable mechanism 2, arranged on the operating table 1, for detachably connecting with the wheel hub and driving the wheel hub to rotate; a mounting frame 3, arranged on the operating table 1, having a cross beam 31 located above the turntable mechanism 2; a tire pressing assembly 4, arranged between the cross beam 31 and the operating table 1; an axis limiting assembly 5, arranged between the cross beam 31 and the operating table 1, for detachably connecting the wheel hub to the turntable mechanism 2 and restricting the axis line of the wheel hub to be collinear with the rotation axis line of the turntable mechanism 2 when the wheel hub rotates. By using the tire mounting machine of the present invention, the user can realize the operations of wheel hub limiting, driving the wheel hub to rotate, and pressing the tire in one stop, improving the tire mounting efficiency.

[0066] In some embodiments of the present invention, optionally, refer to Figures 1 to 3 as shown, the tire pressing assembly 4 includes:

[0067] A first connecting rod 41, one end of which is fixedly connected to the crossbeam 31, and the other end of which is fixedly connected to the operating platform 1;

[0068] The tire pressing member 42 is provided on the first connecting rod 41 and can slide along the length direction of the first connecting rod 41;

[0069] The first cylinder 43 is disposed on the cross beam 31 , and the telescopic arm of the first cylinder 43 is connected to the tire pressing piece 42 , so as to drive the tire pressing piece 42 to slide along the length direction of the connecting rod.

[0070] In the embodiment of the present invention, one end of the first connecting rod 41 is fixedly connected to the crossbeam 31, and the other end is fixedly connected to the operating table 1, extending in the up-down direction. The tire pressing piece 42 can slide along the length direction of the first connecting rod 41, that is, it can slide in the up-down direction. Before the tire installation operation, the tire pressing piece 42 can be lifted upward along the first connecting rod 41 to provide enough space for the wheel hub to enter the tire installation position of the turntable mechanism 2 to avoid interference; and provide enough space for the tire to enter under the tire pressing piece 42, so as to improve the convenience of the tire installation operation.

[0071] In some embodiments of the present invention, optionally, see specifically Figure 2 and Figure 3 As shown, the first connecting rod 41 may be prismatic, and the tire pressing piece 42 has a connecting through hole 42a that penetrates in the up-down direction and can slide with the first connecting rod 41. The above arrangement can limit the tire pressing piece 42 from rotating around the axis of the first connecting rod 41, reduce the risk of the tire pressing piece 42 being displaced by the reaction force of the tire during the tire installation operation (i.e., the tire pressing piece 42 rotates around the axis of the first connecting rod 41), and is conducive to improving the success rate of tire installation, thereby improving the efficiency of tire installation.

[0072] In some optional embodiments, the first connecting rod 41 may be in the shape of a triangular prism. In some optional embodiments, the first connecting rod 41 may be in the shape of a hexagonal prism. In some optional embodiments, the first connecting rod 41 may be in the shape of an octagonal prism. It should be noted that, in actual applications, the specific prism shape of the first connecting rod 41 may be specifically selected by the user according to design requirements, and the present invention does not limit this.

[0073] In some embodiments of the present invention, optionally, see Figures 4 to 6 As shown, the axis limiting assembly 5 includes:

[0074] The second cylinder 51 is provided on the cross beam 31;

[0075] The sleeve 52 is provided on the telescopic arm of the second cylinder 51 and can rotate around the axis of the sleeve 52 . The axis of the sleeve 52 is colinear with the rotation axis of the turntable mechanism 2 .

[0076] In the embodiments of the present invention, the hub is detachably connected to the turntable mechanism 2. Specifically, the user can operate the telescopic arm of the second cylinder 51 to extend downward, so that the sleeve 52 abuts against the hub located at the tire mounting position of the turntable mechanism 2, thereby realizing the connection between the hub and the turntable mechanism 2. It can be understood that when it is necessary to disassemble, the user can operate the telescopic arm of the second cylinder 51 to contract upward, so that the sleeve 52 disengages from the hub located at the tire mounting position of the turntable mechanism 2. At this time, the connection between the hub and the turntable mechanism 2 is released, and the user can remove the hub from the tire mounting position.

[0077] In the embodiments of the present invention, the sleeve 52 can rotate around the axis of the sleeve 52, and the axis of the sleeve 52 is collinear with the rotation axis of the turntable mechanism 2. When the turntable mechanism 2 drives the hub to rotate, the sleeve 52 abutting against the hub can also rotate with the hub, avoiding sliding friction between the sleeve 52 and the hub, preventing friction marks from being formed on the surface of the hub due to sliding friction, and improving the appearance perception of consumers. It can be understood that avoiding sliding friction between the sleeve 52 and the hub can also reduce the failure rate of the turntable mechanism 2 and the sleeve 52, ensuring that the tire mounting machine of the present invention can serve stably for a long time and has a high service life.

[0078] See Figure 5 and Figure 6 As shown, an assembly seat 511 is fixedly arranged at the end of the telescopic arm of the second cylinder 51, and the sleeve 52 is rotatably arranged on the assembly seat 511 through a first bearing 512, realizing the ability to rotate around the axis of the sleeve 52, and the axis of the sleeve 52 is collinear with the rotation axis of the turntable mechanism 2.

[0079] In some embodiments of the present invention, optionally, see Figure 5 and Figure 6 As shown, there are two first bearings 512 arranged at intervals along the axis direction of the telescopic arm, which can prevent the axis of the sleeve 52 from deviating relative to the rotation axis of the turntable mechanism 2 due to wear between components during long-term service, ensuring that the tire mounting machine in the embodiments of the present invention can serve stably for a long time.

[0080] It should be noted that the user can specifically select the specifications and rotational accuracy of the first bearing 512 according to actual needs, and the present invention does not limit this.

[0081] In some embodiments of the present invention, optionally, the tire mounting machine further includes:

[0082] A mounting seat 6, arranged on the telescopic arm of the second cylinder 51, and located above the sleeve 52 in the axial direction of the telescopic arm of the second cylinder 51;

[0083] A tire mounting pressing plate assembly 7, arranged on the mounting seat 6.

[0084] See Figure 5 and Figure 6As shown, an assembly seat 511 is fixedly arranged at the end of the telescopic arm of the second cylinder 51. The sleeve 52 is rotatably arranged on the assembly seat 511 through a first bearing 512, enabling it to rotate around the axis line of the sleeve 52. The axis line of the sleeve 52 is collinear with the rotation axis line of the turntable mechanism 2. The mounting seat 6 is rotatably arranged on the assembly seat 511 through a second bearing and can rotate around the axis line of the telescopic arm of the second cylinder 51.

[0085] In some embodiments of the present invention, optionally, refer to Figure 4 and Figure 5 As shown, the mounting seat 6 has a first through hole 6a penetrating in the up and down direction;

[0086] The tire mounting pressing plate assembly 7 includes:

[0087] The second connecting rod 71 has a first end 71a and a second end 71b at both ends in its own length direction. The first end 71a passes through the first through hole 6a provided and extends to the lower part of the mounting seat 6;

[0088] The pressing plate 72 is arranged at the first end 71a;

[0089] The third cylinder 73 is arranged on the mounting seat 6. The telescopic arm of the third cylinder 73 is connected to the second end 71b and is used to drive the second connecting rod 71 to slide along the first through hole 6a.

[0090] In the embodiments of the present invention, the pressing plate 72 is used to press the tire into the hub groove. The hub groove refers to the groove part on the hub (i.e., the central part of the wheel) for installing the tire. The design and shape of this groove are very important for the fixation and sealing of the tire.

[0091] In the embodiments of the present invention, the mounting seat 6 has a first through hole 6a penetrating in the up and down direction; the tire mounting pressing plate assembly 7 includes: the second connecting rod 71 having a first end 71a and a second end 71b at both ends in its own length direction, the first end 71a passing through the first through hole 6a provided and extending to the lower part of the mounting seat 6; the pressing plate 72 arranged at the first end 71a; the third cylinder 73 arranged on the mounting seat 6, the telescopic arm of the third cylinder 73 being connected to the second end 71b and used to drive the second connecting rod 71 to slide along the first through hole 6a, realizing the up and down displacement of the pressing plate 72 relative to the hub. When it is necessary to press the tire into the hub groove, the user can operate the telescopic arm of the third cylinder 73 to extend downward, so that the pressing plate 72 presses the tire, providing the downward pressure required for the tire to enter the hub groove. After completing the operation of pressing the tire into the hub groove, the user can operate the telescopic arm of the third cylinder 73 to contract upward, so that the pressing plate 72 disengages from the tire.

[0092] In some embodiments of the present invention, optionally, refer to Figure 7 As shown, the tire mounting machine further includes:

[0093] A driving device 74 is provided on the operation table 1 and is used to drive the turntable mechanism 2 to rotate.

[0094] In the embodiment of the present invention, the rotation of the turntable mechanism 2 specifically refers to the turntable mechanism 2 rotating around the rotation axis of the turntable mechanism 2. That is to say, the driving device 74 is used to drive the turntable mechanism 2 to rotate around the rotation axis of the turntable mechanism 2. When a hub is detachably connected to the turntable mechanism 2, the driving device 74 further drives the hub to rotate.

[0095] In some embodiments of the present invention, optionally, refer to Figure 7 As shown, the driving device 74 includes: a driving motor 741 and a speed reducer 742;

[0096] The power output end of the driving motor 741 is in transmission connection with the power input end of the speed reducer 742, and the power output end of the speed reducer 742 is in transmission connection with the power input end of the turntable mechanism 2.

[0097] It should be noted that the rotational speed of the driving motor 741 often far exceeds the rotational speed requirement of the turntable mechanism 2 for tire mounting operations. Therefore, the speed reducer 742 in the embodiment of the present invention can ensure that the driving motor 741 meets the rotational speed requirement of the turntable mechanism 2. In addition, the speed reducer 742 also has the function of amplifying torque to ensure that the turntable mechanism 2 can drive the hub to rotate.

[0098] In some embodiments of the present invention, the specific scheme for the power output end of the driving motor 741 to be in transmission connection with the power input end of the speed reducer 742 can be that a first belt pulley 75 is provided on the power shaft of the driving motor 741, a second belt pulley 76 is provided on the power input rotating shaft of the speed reducer 742, and a belt 77 is sleeved between the first belt pulley 75 and the second belt pulley 76 to achieve transmission.

[0099] In some embodiments of the present invention, optionally, refer to Figure 7 As shown, the speed reducer 742 is a worm and gear speed reducer.

[0100] A worm and gear speed reducer (also known as a turbine reducer or a worm and gear reducer) is a speed reduction device applied to various mechanical transmission systems. Its main feature is to achieve speed reduction and torque amplification through the combination of a worm and a gear. The basic components of a worm and gear speed reducer include:

[0101] Worm: Usually a helical gear responsible for receiving the input rotational motion.

[0102] Gear: A gear that cooperates with the worm and is responsible for outputting the rotational motion.

[0103] When the worm rotates, its helical teeth drive the turbine to rotate. Since the number of teeth of the worm is usually greater than that of the turbine, when the worm makes one full rotation, the turbine only rotates a certain angle, thus achieving speed reduction.

[0104] The reduction ratio of the turbine and worm reducer can be calculated by the number of teeth of the worm and the turbine. The larger the reduction ratio, the lower the output speed and the higher the output torque.

[0105] The advantages of the turbine and worm reducer include: High reduction ratio: The turbine and worm reducer can achieve a large reduction ratio, which is suitable for applications that require low speed and high torque. Self-locking property: The worm drive has a self-locking property, which can keep the load stable without power, and is suitable for occasions such as lifting and hoisting. Compact structure: Compared with other types of reducers, the structure of the turbine and worm reducer is relatively compact, which is suitable for applications with limited space.

[0106] In the embodiments of the present invention, taking advantage of the compact structure of the turbine and worm reducer, the embodiments of the present invention can effectively reduce the space reserved for installing the reducer on the operation platform 1, avoid interference of the installed reducer 742 with other components, and obtain the rotational speed and high torque required for the turntable mechanism 2 to drive the hub to rotate.

[0107] In some embodiments of the present invention, optionally, the turntable mechanism 2 has a limiting structure 21, and the limiting structure 21 is used to limit the axis line of the hub to be collinear with the rotation axis line of the turntable mechanism 2.

[0108] See Figure 7 As shown, the limiting structure 21 may specifically be a plurality of limiting grooves arranged at intervals along the circumferential direction of the turntable mechanism 2, and the plurality of limiting grooves correspond to the spokes (also called web plates) of the hub one by one. When the spokes of the hub are fitted into the limiting grooves, the axis line of the hub is limited to be collinear with the rotation axis line of the turntable mechanism 2.

[0109] It can be understood that different specifications of hubs have different spoke arrangements, for example, the number of spokes, the size of the spokes, and the spoke spacing are different. Therefore, in actual applications, users can select the turntable mechanism 2 that can match the hub according to actual needs, so that: when the spokes of the hub are fitted into the limiting grooves, the axis line of the hub is restricted to be collinear with the rotation axis line of the turntable mechanism 2.

[0110] In some embodiments of the present invention, optionally, the mounting bracket 3 further includes at least one support column 32,

[0111] One end of the support column 32 is fixedly connected to the operation platform 1, and the other end is fixedly connected to the cross beam 31.

[0112] See Figure 1As shown, in the embodiment of the present invention, there are three support columns 32 arranged at intervals, which play a role in stably supporting the cross beam 31.

[0113] In some embodiments of the present invention, optionally, as shown in Figure 1 the tire mounting machine further includes a controller 8, and the controller 8 includes:

[0114] A first control port, electrically connected to the first cylinder 43, for sending an extension signal or a contraction signal to the first cylinder 43;

[0115] A second control port, electrically connected to the second cylinder 51, for sending an extension signal or a contraction signal to the second cylinder 51;

[0116] A third control port, electrically connected to the third cylinder 73, for sending an extension signal or a contraction signal to the third cylinder 73;

[0117] A fourth control port, electrically connected to the turntable mechanism 2, for sending a rotation signal or a stop rotation signal to the turntable mechanism 2.

[0118] When using the tire mounting machine of the embodiment of the present invention for tire mounting operations, the specific steps are as follows:

[0119] Step 1: Place the wheel hub on the turntable mechanism 2;

[0120] Step 2: Place the solid tire above the wheel hub;

[0121] Step 3: Operate the telescopic arm of the second cylinder 51 to extend downward through the controller 8, and the sleeve 52 moves downward synchronously. When the bottom surface of the sleeve 52 presses against the upper end surface of the wheel hub, operate the second cylinder 51 to stop extending the telescopic arm downward;

[0122] Step 4: Operate the telescopic arm of the first cylinder 43 to extend downward through the controller 8, and the tire pressing member 42 moves downward synchronously along the length direction of the first connecting rod 41. The tire pressing member 42 presses the part of the solid tire in contact with the wheel rim into the wheel rim;

[0123] Step 5: Operate the telescopic arm of the third cylinder 73 to extend downward through the controller 8, and the pressing plate 72 moves downward synchronously to the wheel rim end surface;

[0124] Step 6: Operate the turntable mechanism 2 to rotate through the controller 8, drive the wheel hub to rotate, and the wheel hub drives the solid tire to rotate one circle; when the pressing plate 72 rotates to a specific angle, it immediately rotates back and resets automatically.
