Description

Technical Field

[0001] This utility model relates to the field of tire disassembly and assembly technology, and more specifically, to a tire disassembly and assembly device. Background Technology

[0002] In the tire industry, frequent tire replacement and maintenance are essential, especially in the automotive and heavy vehicle sectors. Traditional tire changing techniques relied primarily on manual operation and simple mechanical assistance. Over time, this has evolved to the use of more advanced tire changing machines. These machines are typically equipped with tire hooks, pneumatic devices, and mechanisms for securing the tire, which can improve the efficiency and safety of tire changing to a certain extent.

[0003] However, existing technologies have revealed some significant shortcomings when dealing with certain types of tires, especially low-profile tires and heavy-duty tires for new energy vehicles:

[0004] Due to their low profile, low-profile tires have a tight fit between the tire edge and the rim, making it difficult to find a suitable entry point for tire removal hooks during positioning. The weight and hardness of tires in new energy vehicles further increase the complexity of positioning, making it difficult for traditional tire removal hooks to be accurately inserted into the tire bead.

[0005] Traditional tire changers require frequent use of the auxiliary arm and manual operation when handling large tires to ensure proper alignment of the tire hook with the tire edge. This not only increases operation time but also places higher demands on the operator's physical strength and skills.

[0006] Directly hooking the tire can easily damage the tire edge when dealing with tires with high hardness (such as low-profile tires and tires with rims), and may even damage the tire liner under strong force, thereby reducing the tire's lifespan and increasing additional maintenance costs. Utility Model Content

[0007] The main purpose of this utility model is to provide a tire disassembly and assembly device to solve the problems in the prior art where it is difficult to position and hook the tires during disassembly, which is time-consuming and labor-intensive.

[0008] To achieve the above objectives, according to one aspect of the present invention, a tire removal and installation device is provided, comprising:

[0009] Tire disassembly structure;

[0010] At least one pressure roller structure is disposed on the tire removal structure; the tire removal structure is movably disposed in a preset direction to drive the pressure roller structure to approach or move away from the tire to be removed; when the pressure roller structure approaches the tire to be removed, the pressure roller structure contacts the outer tire of the tire to be removed to apply force to the outer tire so that a tire removal opening is formed between the outer tire of the tire to be removed and the rim.

[0011] Tire removal hooks are installed on tire removal structures so that the tire removal structures can move the tire removal hooks closer to the tire removal opening. The tire removal hooks are movably installed relative to the tire removal structures so that they can extend into the tire removal opening and disassemble and separate the outer tire and the rim of the tire to be removed.

[0012] Furthermore, the tire removal and installation equipment also includes: a transmission component, which is mounted on the tire removal structure; the transmission component is movably mounted relative to the tire removal structure along a first direction; the tire removal hook is movably connected to the transmission component; and a guide portion is provided on the tire removal structure.

[0013] The tire hook engages with the guide portion via the engaging component, so that when the transmission component moves in the first direction, the tire hook moves along the extension direction of the guide portion under the action of the engaging component and the guide portion; at least a portion of the guide section of the guide portion is set at an angle to the first direction.

[0014] Furthermore, the guide portion includes: a first guide portion, the first guide portion including a first guide segment, the extension direction of the first guide segment being set at an angle to the extension direction of the axis of the transmission component;

[0015] The mating components include a first mating part, which is rotatably disposed relative to the tire removal hook about a first axis;

[0016] The first guide section is a strip-shaped groove, the first mating part passes through the tire removal hook and is slidably connected to the first guide section, and the extension direction of the first axis is perpendicular to the preset direction and the first direction.

[0017] Furthermore, the first guide section also includes:

[0018] The second guide section is connected to the first guide section, and the extension direction of the second guide section is set at an angle to the extension direction of the axis of the transmission component.

[0019] The second guide section is a strip-shaped groove.

[0020] Furthermore, the guide section also includes: a second guide section;

[0021] The mating components also include a second mating part, which is rotatably arranged relative to the tire removal hook about a second axis;

[0022] The second axis is perpendicular to the preset direction and the first direction, and parallel to the extension direction of the first axis.

[0023] Furthermore, the tire removal hook and the transmission component are rotatably configured, and the tire removal hook can rotate about the second axis;

[0024] The second axis extends perpendicularly to the first direction and the preset direction.

[0025] Furthermore, the pressure roller structure includes a pressure roller component, which is rotatably arranged relative to the tire removal structure about a fourth axis, so that when the tire to be removed rotates, it drives the pressure roller component to rotate about the fourth axis.

[0026] The fourth axis extends perpendicularly to the axis of the tire to be removed.

[0027] Furthermore, tire changing equipment also includes:

[0028] An auxiliary mounting component is disposed on the tire removal structure. This structure moves the auxiliary mounting component closer to the rim of the tire to be installed along a predetermined direction, causing it to adhere to the inner side of the first or second edge of the outer tire. When the tire rotates, the auxiliary mounting component provides support to the outer tire, thus completing the installation of the rim and the outer tire. Further, there are two auxiliary mounting components, with the outer tire having a first and a second edge along its circumference.

[0029] The two auxiliary mounting parts are located on both sides of the tire removal structure, and the two auxiliary mounting parts extend in opposite directions. One auxiliary mounting part is used to cooperate with the first edge, and the other auxiliary mounting part is used to cooperate with the second edge.

[0030] Furthermore, tire changing equipment also includes:

[0031] The first drive structure has a drive unit that is connected to the tire removal hook drive to drive the tire removal hook to move closer to the tire removal opening relative to the tire removal structure.

[0032] The second drive structure has a drive unit connected to the main body of the first drive structure to drive the tire removal hook to approach the tire removal opening relative to the tire removal structure.

[0033] The second drive structure has a drive unit connected to the main body of the first drive structure to drive the first drive structure and the tire removal hook together toward the tire to be removed.

[0034] Applying the technical solution of this utility model, during use, firstly, the tire removal structure guides the pressure roller structure close to the tire to be removed. Through the uniform pre-pressure of the tire's outer casing by the pressure roller structure, a tire removal opening gradually forms between the tire's outer casing and the rim. The key to this process lies in the balance of forces generated when the pressure roller structure contacts the tire's outer casing, ensuring that the tire's outer casing can create sufficient separation space from the rim without damage.

[0035] Once the tire removal opening is formed, the tire removal mechanism moves the tire removal hook towards it until it accurately enters the opening. This step relies on the precise matching of the tire removal hook and the tire removal opening position, allowing the hook to hook onto the tire edge without damaging it. After entering the opening, the tire removal hook uses the power of the tire removal mechanism to smoothly pull the outer edge of the tire to be removed along a preset trajectory, ultimately separating the tire from the rim.

[0036] The mobility of the tire removal structure allows the equipment to flexibly handle the removal of tires of different sizes and types, enhancing its versatility and ease of operation. This design allows the pressure roller structure to precisely adjust its relative position to the tire as needed. The pressure roller structure, positioned on the tire removal structure, applies pressure to the tire's outer layer as it approaches the tire, creating a removal opening. Through the pre-pressure applied to the tire by the pressure roller structure, a removal opening can be safely and non-destructively created between the tire's outer layer and the rim. This opening not only reduces the risk of damage to the tire during removal but also provides a clear entry point for the precise insertion of the tire removal hook. The tire removal hook, positioned on the tire removal structure, can be moved closer to the removal opening by the structure and can then be inserted to separate the tire's outer layer from the rim. The design of the tire removal hook fully utilizes the advantageous condition created by the pressure roller structure—the existence of the removal opening. When the tire hook is accurately inserted into the tire removal opening under the guidance of the tire removal structure, it can effectively hook the edge of the tire using its special shape and material. Then, through the power transmission of the tire removal structure, the tire is smoothly separated from the rim, avoiding the destructive operation that may be caused by traditional tire removal tools.

[0059] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0060] As mentioned in the background section, the purpose of this application is to provide a tire removal and installation device to solve the problems in the prior art where it is difficult to position and hook the tires during the removal process of low-profile tires and new energy vehicle tires, which is time-consuming and labor-intensive.

[0061] The tire removal and installation equipment provided in this application includes a tire removal structure 2; at least one pressure roller structure 3, disposed on the tire removal structure 2; the tire removal structure 2 is movably disposed in a preset direction to drive the pressure roller structure 3 to approach or move away from the tire 8 to be removed; when the pressure roller structure 3 approaches the tire 8 to be removed, the pressure roller structure 3 contacts the outer tire of the tire 8 to be removed to apply force to the outer tire, so that a tire removal opening 9 is formed between the outer tire of the tire 8 to be removed and the rim; a tire removal hook 4 is disposed on the tire removal structure 2 so that the tire removal structure 2 drives the tire removal hook 4 to approach the tire removal opening 9; the tire removal hook 4 is movably disposed relative to the tire removal structure 2 to extend into the tire removal opening and disassemble and separate the outer tire of the tire 8 to be removed and the rim of the tire 8 to be removed.

[0062] Specifically, such as Figures 1 to 18As shown, the tire removal and installation equipment provided in this application includes a tire removal structure 2 and a rotating support platform for supporting the tire 8 to be removed (not shown in the figure, but it should be noted that the rotating support platform of this application is located below at least part of the structure in the tire removal and installation equipment). The side view of the tire removal structure 2 is shown below. Figure 2 As shown, the exploded view of tire removal structure 2 is as follows: Figure 3 As shown, a pressure roller structure 3 is provided on the tire removal structure 2. In this embodiment, when the number of pressure roller structures 3 is one, as follows: Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the tire removal structure 2 can be movable along a preset direction, where the preset direction is the direction in which the tire removal structure 2 moves relatively closer to or further away from the rotating support platform. Figure 2 In the preset direction, the tire removal structure 2 moves in the vertical direction, which can drive the pressure roller structure 3 to move closer to or away from the tire 8 to be removed. When tire removal is required, the tire removal structure 2 will move the pressure roller structure 3 towards the tire 8 to be removed. When the pressure roller structure 3 contacts the outer tire of the tire 8 to be removed, it applies a force to the outer tire of the tire 8 to be removed, thereby forming a tire removal opening 9 between the outer tire of the tire 8 and the rim. Figure 9 The diagram shows the contact between the pressure roller structure 3 and the outer tire of the tire 8 to be removed. Figure 10 As shown, the tire removal opening 9 is formed between the outer tire and the rim of the tire to be removed 8 under the action of the pressure wheel structure 3. A tire removal hook 4 is also provided on the tire removal structure 2. When the tire removal structure 2 moves, it can drive the tire removal hook 4 closer to the tire removal opening 9. The tire removal hook 4 is movably arranged relative to the tire removal structure 2, so that the tire removal hook 4 can extend into the tire removal opening 9. Figure 11 As shown, when the tire removal hook 4 is inserted into the tire removal opening 9, the end of the tire removal hook 4 (the hooked part) directly hooks the outer tire of the tire to be removed 8. As the tire removal structure 2 moves the tire removal hook 4 away from the tire removal opening 9, the outer tire of the tire to be removed 8 gradually separates from the rim of the tire to be removed 8 under the action of the end of the tire removal hook 4. Figure 12 As shown, the rotating support platform is then controlled to rotate, thus completing the separation of the outer tire and rim of the tire to be removed 8, thereby completing the tire removal.

[0063] Furthermore, the number of pressure roller structures 3 in this application can be one or more. When the number of pressure roller structures 3 is one, its structure and position are as shown above, and the schematic diagram is as follows. Figure 2 , Figure 3 and Figure 4 As shown, when there are multiple pressure roller structures 3, their structure is as follows: Figure 19As shown, two pressure roller structures 3 are respectively arranged on both sides of the tire removal structure 2 and are symmetrically distributed relative to the tire removal structure 2. When there are two pressure roller structures 3, there is only one auxiliary mounting part, specifically the second auxiliary part 2015. At the same time, a pressure roller structure 3 can also be set below the main sleeve 203, which can realize the formation of the tire removal opening 9. Among them, when there are two pressure roller structures 3, the structure of the pressure roller structure 3 is the same as the structure when there is only one pressure roller structure 3. However, the difference is that when there are two pressure roller structures 3, a connecting part 303 is provided between the pressure roller structure 3 and the tire removal structure 2. The connecting part 303 is directly fixedly connected to the pressure roller body 301. The pressure roller component 302 can rotate around the axis of the pressure roller body 301. Figure 9 As shown, the pressure roller structure 3 is installed on the tire removal structure 2 in this way.

[0064] The mobility of the tire removal structure 2 allows the tire removal equipment to precisely position itself on the tire 8 to be removed, enhancing operational accuracy and reliability. The ability to move in a preset direction ensures that the tire removal equipment can be quickly adjusted according to different tire sizes and positions, improving adaptability to various tire types. When the tire removal structure 2 moves the pressure roller structure 3 closer to the tire, the effectiveness of the pressure roller structure 3 is maximized, reducing pre-treatment time before tire removal. The pressure roller structure 3, mounted on the tire removal structure 2, can contact and apply pressure to the outer surface of the tire 8 to be removed when the tire removal structure 2 approaches the tire 8, creating a tire removal opening 9 between the tire 8 and the rim.

[0065] The pre-compression function of the pressure roller structure 3 helps to avoid tire damage caused by directly using the tire removal hook 4, ensuring tire protection during the removal process. Under the pressure of the pressure roller structure 3, a gap is formed between the outer tire of the tire to be removed 8 and the rim, creating conditions for the intervention of the tire removal hook 4. The use of the pressure roller structure 3 reduces the amount of preparation work before tire removal and speeds up the entire removal process. The tire removal hook 4 is movably mounted on the tire removal structure 2 and can extend into the tire removal opening 9 formed by the pressure roller structure 3 as the tire removal structure 2 moves, thereby hooking the outer tire of the tire to be removed 8 and separating the outer tire of the tire to be removed 8 from the rim.

[0066] The telescopic design of the tire removal hook 4 makes the disassembly process smoother, eliminating the need for complex auxiliary operations and reducing the labor intensity of workers. The intervention of the tire removal hook 4, along with the assistance of the rotating support platform, ensures the non-destructive separation of the tire 8 from the rim, enhancing the safety and practicality of the equipment. Working in conjunction with the pressure wheel structure 3, the tire removal hook 4 significantly improves tire removal speed and reduces overall disassembly and assembly time through precise insertion and hooking actions.

[0067] By integrating the tire removal hook 4 and the pressure roller structure 3 onto the tire removal structure 2, seamless connection of each step in the tire removal process is ensured, avoiding the time waste caused by frequent tool switching in traditional tire removal and assembly.

[0068] The integrated design enables tire changers to not only efficiently remove tires but also install them without altering the equipment's position, thus enhancing the overall service capabilities of the tire changer.

[0069] Furthermore, the tire removal and installation equipment also includes: a transmission component 202, which is disposed on the tire removal structure 2; the transmission component 202 is movably disposed relative to the tire removal structure 2 along a first direction; the tire removal hook 4 is movably connected to the transmission component 202; and a guide portion is provided on the tire removal structure 2.

[0070] The tire hook 4 is engaged with the guide portion through the engaging component 5, so that when the transmission component 202 moves in the first direction, the tire hook 4 moves along the extension direction of the guide portion under the action of the engaging portion and the engaging component 5; at least a portion of the guide portion is set at an angle to the first direction in the extension direction of the guide portion.

[0071] Specifically, the tire removal and installation equipment also includes a transmission component 202 mounted on the tire removal structure 2. In this embodiment, the transmission component 202 is a drive shaft, such as... Figure 2 and Figure 3 As shown, the transmission component 202 is movably arranged relative to the tire removal structure 2 along a first direction. The tire removal hook 4 is movably connected to one end of the transmission component 202. When the transmission component 202 moves along the first direction, the tire removal hook 4 will also move synchronously under the action of the transmission component 202. A guide portion is provided on the tire removal structure 2. The tire removal and installation equipment also includes a mating component 5 that cooperates with the guide portion, such as... Figure 2 and Figure 3 As shown, the guide portion restricts the movement trajectory of the tire removal hook 4. With the cooperation of the cooperating component 5, the tire removal hook 4 can move along the extension direction of the guide portion and enter the tire removal opening 9 to complete the tire removal operation. At least a portion of the guide portion's extension direction forms an angle with a first direction, where the first direction is... Figure 3 The direction of movement of the transmission component 202, that is... Figure 2 The horizontal direction in the middle.

[0072] Tire disassembly structure 2 includes disassembly / assembly body 201, such as Figure 2 As shown, the disassembly / assembly main body 201 includes a first disassembly / assembly part 2011, which includes multiple segments distributed along a first direction. Figure 2The components are divided into three segments from left to right: the first segment, the second segment, and the third segment. The first segment is inclined downwards, and the lowest point of the first segment forms an acute angle with the axial extension direction of the transmission component 202. The second segment is a rounded transition segment, and the third segment is a straight segment. The disassembly and assembly main body 201 also includes a second disassembly and assembly part 2012 and a third disassembly and assembly part 2013. The structure of the second disassembly and assembly part 2012 is the same as that of the third disassembly and assembly part 2013. The second disassembly and assembly part 2012 and the third disassembly and assembly part 2013 are symmetrically arranged with respect to the axial direction of the transmission component 202. There are two guide parts, which are respectively arranged on the second disassembly and assembly part 2012 and the third disassembly and assembly part 2013. The guide parts on the second disassembly and assembly part 2012 and the third disassembly and assembly part 2013 are symmetrical along the axial direction of the transmission component 202. Therefore, under the combined action of the cooperating component 5 and the two guide parts, the tire removal hook 4 moves along the extension direction of the guide parts and enters the tire removal opening 9 to complete the tire removal operation.

[0073] The main body 201 is the carrier platform of the entire tire disassembly and assembly equipment, which includes the first disassembly and assembly section 2011, the second disassembly and assembly section 2012 and the third disassembly and assembly section 2013.

[0074] The first segment is inclined downwards, forming an acute angle with the axial extension direction of the transmission component 202. This design provides directional guidance for the initial movement of the tire removal hook 4, making it easy for the tire removal hook 4 to smoothly extend into the tire removal port 9.

[0075] The inclined design of the first segment ensures that the tire removal hook 4, driven by the transmission component 202, can smoothly transition to the optimal angle of contact with the tire to be removed 8, avoiding the obstacles that the tire removal hook 4 might encounter when falling directly vertically, and achieving a smoother removal process.

[0076] The movement of the transmission component 202 drives the tire removal hook 4 to move synchronously along the first direction, ensuring that the tire removal hook 4 can be accurately positioned at the tire removal opening 9, while providing the driving force required for tire removal. The linear motion of the transmission component 202 is converted into the extension and retraction of the tire removal hook 4. This conversion process is achieved through the movable connection between the transmission component 202 and the tire removal hook 4, allowing the tire removal hook 4 to move freely on a preset trajectory, thereby ensuring that it is accurately inserted into the tire removal opening 9 to complete tire removal.

[0077] The selection of the first direction takes into account the relative position of the tire 8 to be removed and the rim, as well as the necessary angle for the tire removal hook 4 to extend into the tire removal port 9. This setting allows the movement of the transmission component 202 to be directly converted into the effective action of the tire removal hook 4, ensuring smooth and efficient operation of the equipment.

[0078] The guide portion restricts the movement trajectory of the tire removal hook 4, ensuring it can extend into the tire removal opening 9 along the optimal route and avoiding tire damage that may result from blind movement. The symmetrical arrangement of the guide portion and the angle setting in the first direction together constitute the movement trajectory planning of the tire removal hook 4. When the tire removal hook 4 moves under the drive of the transmission component 202, the guide portion guides its movement direction, enabling it to complete the positioning and smooth insertion of the tire removal opening 9 within the shortest path, thereby optimizing the disassembly process and improving work efficiency.

[0079] The coordinated action of the cooperating component 5 and the guide can be seen as a fine-tuning mechanism for the movement trajectory of the tire removal hook 4. After the transmission component 202 provides power transmission, the precise control of the guide and the cooperating component 5 ensures that the tire removal hook 4 can accurately extend into the tire removal opening 9, avoiding errors and potential damage during operation.

[0080] The symmetrical design of the second assembly / disassembly section 2012 and the third assembly / disassembly section 2013 ensures balance throughout the assembly / disassembly process and avoids the impact of eccentric movement on equipment stability. The symmetrical structural design takes into account the center position of the tire and the balanced force distribution of the tire removal hook 4, so that the equipment can maintain a good balance when removing the tire, preventing damage to the tire or equipment due to excessive force on one side.

[0081] The formation of the tire removal opening 9 ensures that the tire removal hook 4 can smoothly insert into the gap between the tire 8 to be removed and the rim, simplifying the removal process and avoiding potential damage to the tire caused by traditional removal methods. The pre-compression action of the pressure wheel structure 3 creates the tire removal opening 9, and the size and position of this opening directly affect whether the tire removal hook 4 can successfully perform the removal task. The accurate formation of the tire removal opening 9 is crucial for the successful insertion of the tire removal hook 4.

[0082] The main assembly / disassembly body 201, transmission component 202, guide part, mating component 5, and tire removal port 9 work together to enable the tire removal hook 4 to efficiently and safely complete the tire removal operation. The orderly cooperation of each component ensures that every step of the tire removal process can be reasonably controlled. From positioning to pre-compression, from transmission to guidance, until the tire removal hook 4 extends into the tire removal port 9, the entire process is interlocked, ultimately achieving tire removal without damage and quickly.

[0083] Furthermore, the guide section includes:

[0084] The first guide portion 7 includes a first guide section 701, the extension direction of the first guide section 701 is set at an angle to the extension direction of the axis of the transmission component 202;

[0085] The mating component 5 includes a first mating part 501, which is rotatably arranged relative to the tire removal hook 4 about a first axis.

[0086] The first guide section 701 is a strip groove, the first mating part 501 passes through the tire removal hook 4 and is slidably connected to the first guide section 701, and the extension direction of the first axis is perpendicular to the preset direction and the first direction.

[0087] The first guide section 7 also includes:

[0088] The second guide section 702 is connected to the first guide section 701, and the extension direction of the second guide section 702 is set at an angle to the extension direction of the axis of the transmission component 202.

[0089] The second guide section 702 is a strip-shaped groove;

[0090] The guidance section also includes:

[0091] Second guide section 6;

[0092] The mating component 5 also includes a second mating part 502, which is rotatably arranged relative to the tire removal hook 4 about the second axis;

[0093] The second axis is perpendicular to the preset direction and the first direction, and parallel to the extension direction of the first axis.

[0094] Specifically, the guide section includes a first guide section 7 and a second guide section 6, such as... Figure 3 As shown, the first guide portion 7 is a first guide groove, and the first guide portion 7 includes a first guide section 701, which is a strip-shaped groove, such as... Figure 13 As shown, the extending direction of the first guide section 701 forms an angle of 71° with the extending direction of the axis of the transmission component 202. The mating component 5 includes a first mating part 501, which is a pin in this embodiment. The first guide part 7 also includes a second guide section 702 communicating with the first guide section 701. The second guide section 702 is a strip groove, and its extending direction forms an angle of 15° with the axial direction of the transmission component 202. A second hinge hole 402 is provided on the tire removal hook 4. Figure 3 As shown, the second hinge holes 402 are arranged in pairs. One end of the first mating member 501 extends into one of the second hinge holes 402 and extends out of the other second hinge hole 402. The two ends of the first mating member 501 located outside the tire removal hook 4 are respectively arranged in the corresponding two first guide portions 7 and extend out of the first guide portions 7 to the outside, and are slidably connected with the first guide portions 7. The first mating member 501 can be rotated relative to the disassembly and assembly body 201 around the first axis.

[0095] The second guide section 6 is a strip-shaped groove, such as Figure 3As shown, the second guide portion 6 extends along the first direction, and the mating component 5 also includes a second mating member 502. In this embodiment, the second mating member 502 is a pin. A first hinge hole 401 is also provided on the tire removal hook 4. Figure 3 As can be seen, the first hinge hole 401 and the second hinge hole 402 are arranged along the extension direction of the tire removal hook 4. The first hinge holes 401 are arranged in pairs. One end of the second mating member 502 extends into one of the first hinge holes 401 and extends out of the other first hinge hole 401. The two ends of the second mating member 502 located outside the tire removal hook 4 are respectively set in the two corresponding second guide portions 6 and extend out of the second guide portions 6 to the outside, and are slidably connected with the second guide portions 6. The second mating member 502 can be rotated relative to the disassembly and assembly body 201 around the second axis. Protective pads are provided at both ends of the first mating member 501 and the second mating member 502 to ensure that the first mating member 501 and the second mating member 502 will not detach from the first guide portion 7 and the second guide portion 6 during use.

[0096] In another embodiment of this application, the extending direction of the first guide segment 701 is consistent with the extending direction of the second guide segment 702. In this case, the included angle between the first guide segment 701 and the second guide segment 702 is 180 degrees. At this time, the tire hook 4 is not... Figure 8 Instead of entering the tire removal port 9 at a vertical angle to perform the tire removal operation, the tire removal operation is performed by entering the tire removal port 9 at a certain inclined angle. That is, as long as the end of the tire removal hook 4 can be inserted into the tire removal port 9 so that the end of the tire removal hook 4 hooks onto the tire bead of the outer tire of the tire to be removed 8, the tire removal operation can be achieved.

[0097] During use, when tire removal is required, the tire removal opening 9 is first formed using the pressure roller structure 3. At this time, the first mating part 501 and the second mating part 502 are in their original positions, as shown in the image. Figure 5 and Figure 9 As shown;

[0098] After the tire opening 9 is formed, the transmission component 202 drives the tire removal hook 4 to enter through the tire opening 9. At this time, the first mating component 501 and the second mating component 502 are in the first preset position, such as... Figure 6 and Figure 10 As shown;

[0099] When the tire removal hook 4 enters the tire removal port 9, the transmission component 202 continues to drive the tire removal hook 4 to move, so that the tire removal hook 4 hooks the outer tire of the tire 8 to be removed. At this time, the first mating part 501 and the second mating part 502 are in the second preset position, such as... Figure 7 and Figure 11 As shown;

[0100] Then, driven by the tire removal structure 2, the tire removal hook 4 moves away from the tire 8 to be removed. At this time, the first mating part 501 and the second mating part 502 are in the third preset position, such as... Figure 8 and Figure 11 As shown, in Figure 8 and Figure 11 In the middle, the tire removal hook 4 is in a vertical position. At this time, the end of the tire removal hook 4 will drive the outer tire of the tire to be removed 8 to gradually move away from the wheel hub of the tire to be removed 8, thereby completing the removal of the outer tire of the tire to be removed 8 from the wheel hub.

[0101] The first guide section 7, particularly the first guide segment 701, guides the first mating member 501 to move obliquely at 71°, ensuring that the tire removal hook 4 can approach the tire removal opening 9 along the optimal path, reducing initial contact resistance and improving disassembly efficiency. The 71° included angle design of the first guide segment 701 is intended to allow the tire removal hook 4 to contact the outer tire of the tire to be removed 8 at a relatively gentle angle when the transmission component 202 moves along the first direction, avoiding tire damage or disassembly failure due to an unsuitable angle.

[0102] The 15° angle of the second guide section 702 further guides the tire removal hook 4 deeper into the interior of the tire 8 to be removed, ensuring that the tire removal hook 4 can accurately hook onto the outer edge of the tire 8 to be removed, thus completing the removal operation. After the tire removal hook 4 initially contacts the outer edge of the tire 8 to be removed, the precise angle setting of the second guide section 702 enables the tire removal hook 4 to move smoothly inside the tire 8 to be removed, avoiding the inability to effectively hook onto the edge of the outer edge of the tire 8 to be removed due to an angle that is too large or too small, thereby ensuring the smooth completion of the removal operation.

[0103] The function of the first mating component 501 is to convert the linear motion of the transmission component 202 into the rotational and linear motion of the tire removal hook 4, ensuring that the tire removal hook 4 can accurately contact the tire to be removed 8. When the transmission component 202 pushes the tire removal hook 4, the first mating component 501, through its interaction with the first guide part 7, ensures that the tire removal hook 4 can be adjusted to a suitable angle before contacting the tire, thereby smoothly extending into the tire removal opening 9 and achieving effective separation of the outer tire of the tire to be removed 8 from the rim.

[0104] The function of the second mating component 502 is to control the depth to which the tire removal hook 4 penetrates into the tire 8 to be removed, ensuring that the hook can firmly hook onto the edge of the outer tire of the tire 8 to be removed, without being too deep or too shallow, which would affect the removal effect. After the tire removal hook 4 initially extends into the tire removal opening 9, the second mating component 502, guided by the second guide part 6, controls the tire removal hook 4 to make an arc movement until it reaches the optimal hooking position, that is, the stop between the outer tire of the tire 8 to be removed and the rim, ensuring that the tire removal hook 4 can accurately hook onto the outer tire of the tire 8 to be removed, avoiding tire damage caused by insufficient or excessive hooking force.

[0105] The paired first hinge hole 401 and second hinge hole 402 provide the tire removal hook 4 with rotational flexibility around the first axis and the second axis, ensuring that the tire removal hook 4 can smoothly follow the trajectory of the guide. Without the hinge holes, the first mating part 501 and the second mating part 502 cannot achieve rotational connection with the tire removal hook 4, which would restrict the movement path of the tire removal hook 4, thus preventing it from effectively extending into and hooking the outer tire of the tire 8 to be removed. The hinge holes solve this problem, making the movement of the tire removal hook 4 more in line with the removal requirements.

[0106] The formation of the tire removal opening 9 simplifies the process of the tire removal hook 4 inserting into the tire 8 to be removed, ensuring the smooth progress of the removal action and avoiding potential damage to the tire 8 that might be caused by directly using the tire removal hook 4. The pressure wheel structure 3 pre-presses the outer tire of the tire 8 to be removed to form the tire removal opening 9, providing a clear entry point for the tire removal hook 4, allowing the tire removal hook 4 to extend into the tire along this preset path, reducing direct impact on the tire 8 to be removed, and ensuring the integrity and safety of the tire 8 to be removed during the removal process.

[0107] The orderly disassembly process ensures that each step is executed precisely. From the formation of the tire removal opening 9 to the final separation of the tire 8 from the rim, each step is carefully designed to guarantee the efficiency and safety of the entire disassembly process. Through the coordinated work of the above components, from the formation of the tire removal opening 9 by the pressure roller structure 3, to the movement of the first mating part 501 and the second mating part 502 along the first guide part 7 and the second guide part 6 respectively, until the tire removal hook 4 penetrates and rotates, the separation of the tire 8 from the rim is finally completed.

[0108] Furthermore, the tire removal hook 4 is rotatably disposed with the transmission component 202, and the tire removal hook 4 can rotate about the second axis;

[0109] The second axis extends perpendicularly to the first direction and the preset direction.

[0110] Specifically, the tire removal hook 4 and the transmission component 202 are rotatably connected by the second mating member 502. That is, the second mating member 502 connects the tire removal hook 4 with the transmission component 202 and the second guide part 6, and the tire removal hook 4 can rotate around the second axis.

[0111] The second mating component 502, as a key component connecting the tire removal hook 4 and the transmission component 202, not only transmits motion but also allows the tire removal hook 4 to adjust its posture under the combined action of the first hinge hole 401 and the second guide part 6 to adapt to different tire removal requirements of the tire 8 to be removed. The rotation mechanism of the second mating component 502 allows the tire removal hook 4 to adjust its vertical angle according to the path change of the guide part while moving horizontally, ensuring the accuracy of the angle of the tire removal hook 4 when it is inserted into the tire removal hole 9, thereby reducing the risk of damage during tire removal.

[0112] The first guide section 7 guides the extension and retraction direction of the tire removal hook 4 by setting different included angles between the first guide section 701 and the second guide section 702. The second guide section 6 extends along the first direction, restricting the linear movement path of the tire removal hook 4 and ensuring the continuity and accuracy of the disassembly process. The 70° angle between the first guide section 701 and the axis of the transmission component 202, and the 15° angle between the second guide section 702, together determine the initial posture and subsequent posture adjustment of the tire removal hook 4 when it extends into the tire removal opening 9. The second guide section 6 provides horizontal guidance for the tire removal hook 4, ensuring its straightness during extension and retraction.

[0113] The tire removal hook 4, connected to the second mating part 502 via the first hinge hole 401, enables rotation around the second axis. Simultaneously, the engagement of the second hinge hole 402 with the first mating part 501 ensures that the tire removal hook 4 can extend and retract along the path of the first guide part 7 under the drive of the transmission component 202. The combination of the first hinge hole 401 and the second mating part 502 allows for vertical adjustment of the tire removal hook 4; while the engagement of the second hinge hole 402 with the first mating part 501 ensures the stability of the tire removal hook 4 during extension and retraction along the first guide part 7. This multi-axis linkage design allows the tire removal hook 4 to be flexibly adjusted in multiple degrees of freedom to adapt to tires 8 of different shapes and sizes to be removed, while maintaining stability and control precision.

[0114] The different positions of the tire removal hook 4 before and after entering the tire removal opening 9 enable phased control of the tire removal process 8. In particular, the transition between the second and third preset positions demonstrates the complete control of the tire removal hook 4 from entering the tire removal opening 9 to fully hooking the outer tire of the tire 8, and finally completing the removal. In the initial position, a certain distance is maintained between the tire removal hook 4 and the tire 8 to facilitate the formation of the tire removal opening 9 by the pressure wheel structure 3. Subsequently, in the first preset position, the tire removal hook 4 begins to extend into the tire removal opening 9 along the path of the first guide 7. Upon reaching the second preset position, the tire removal hook 4 fully hooks the outer tire of the tire 8. At this point, it is necessary to further separate the outer tire of the tire 8 from the rim along the path of the second guide 6. Finally, in the third preset position, the tire removal hook 4 completes the tire removal and withdraws. The entire process, through the precise control of the guide and the mating components (the second mating component 502 and the first mating component 501), achieves safe and efficient management of the entire tire removal process 8.

[0115] Furthermore, the pressure roller structure 3 includes a pressure roller component 302, which is rotatably arranged relative to the tire removal structure 2 about a fourth axis, so that when the tire to be removed 8 rotates, the pressure roller component 302 is driven to rotate about the fourth axis.

[0116] The fourth axis extends perpendicularly to the axis of the tire 8 to be removed.

[0117] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the pressure roller structure 3 includes a pressure roller component 302, which is cylindrical in this embodiment, as shown below. Figure 17 As shown, the pressure roller structure 3 also includes a pressure roller body 301 that works in conjunction with the pressure roller component 302. In this embodiment, the pressure roller body 301 is a support rod.

[0118] A baffle plate 2016 is also provided at the end of the second disassembly section 2012 and the third disassembly section 2013 that is away from the first disassembly section 2011, such as... Figure 18As shown, the extending direction of the baffle plate 2016 is consistent with the extending direction of the axis of the transmission component 202. The baffle plate 2016, the first disassembly / assembly part 2011, the second disassembly / assembly part 2012, and the third disassembly / assembly part 2013 together form a movement space for the tire hook 4 to move. A mounting component 2017 is provided below the baffle plate 2016 away from the first disassembly / assembly part 2011. The mounting components 2017 are arc-shaped and appear in pairs. Each mounting component 2017 has a mounting hole 2018. Both ends of the pressure roller body 301 can extend into two mounting holes 2018 respectively, and the two ends of the pressure roller body 301 are connected to the mounting components 2017 by bolts. The pressure roller component 302 can rotate around the axis of the pressure roller body 301, thereby enabling the pressure roller structure 3 to be installed on the tire removal structure 2. When removing the tire, when the pressure roller component 302 contacts the outer tire of the tire to be removed 8, the rotating support platform will drive the tire to be removed 8 to rotate. During the rotation of the outer tire of the tire to be removed 8, due to the force between the pressure roller component 302 and the outer tire of the tire to be removed 8, the pressure roller component 302 will also rotate simultaneously with the tire to be removed 8. However, the axis of rotation of the tire to be removed 8 is its own axis, which is perpendicular to the fourth axis of rotation of the pressure roller component 302. This arrangement can ensure that the outer tire of the tire to be removed 8 will not be damaged due to the tire removal equipment during the tire removal operation.

[0119] When the cylindrical pressure roller component 302 contacts the outer surface of the tire to be removed 8, it can evenly distribute the pressure, avoiding excessive local force that could damage the outer surface of the tire to be removed 8. The design of the cylindrical pressure roller component 302 ensures that the pressure can be evenly distributed laterally along the outer surface of the tire to be removed 8 when it contacts the outer surface of the tire to be removed 8. When the tire to be removed 8 rotates, the pressure roller component 302 rotates accordingly, maintaining a constant contact area and pressure distribution, thereby effectively preventing damage to the outer surface of the tire to be removed 8 in the initial stage of disassembly.

[0120] The pressure roller body 301 serves as a support structure, providing necessary support for the pressure roller component 302 while allowing the pressure roller component 302 to rotate freely around its axis, ensuring the flexibility and efficiency of the tire pre-pressing operation of the tire to be removed 8. As a connection point, the pressure roller body 301 must bear the weight of the pressure roller component 302 and the pressure generated during pre-pressing; furthermore, its design must allow the pressure roller component 302 to rotate freely to accommodate the rotation of the tire to be removed 8, maintaining effective pre-pressing contact and ensuring that the tire to be removed 8 is not damaged during the pressure roller operation.

[0121] The baffle plate 2016, together with the other parts of the disassembly and assembly body 201, forms the movement space of the tire removal hook 4, effectively limiting the range of motion of the tire removal hook 4 and ensuring safety during operation. The position setting of the baffle plate 2016 ensures that the tire removal hook 4 will not exceed the preset range during movement, avoiding accidental collisions or derailment that may occur during movement, and providing a safer working environment for the operator.

[0122] The arc-shaped design of the mounting component 2017 facilitates the installation of the pressure roller body 301, while the bolt fixing method ensures the firmness and stability of the pressure roller structure 3 during disassembly and assembly operations, avoiding vibration and displacement during the process. The arc-shaped design of the mounting component 2017 matches the shape of the pressure roller body 301, allowing the pressure roller body 301 to be easily inserted into the mounting hole 2018; the bolt fixing method further strengthens the connection strength between the pressure roller structure 3 and the disassembly and assembly body 201, ensuring that even under large reaction forces during tire removal, the pressure roller structure 3 remains stable and will not loosen or fall off, guaranteeing the safety and efficiency of the disassembly operation.

[0123] The mounting holes 2018 provide a precise mounting position for the pressure roller body 301. By adjusting the position of the pressure roller body 301 in different mounting holes 2018, the contact surface between the pressure roller component 302 and the outer tire of the tire to be removed 8 can be fine-tuned, thus adapting to tires of different sizes and types. Different tire widths and diameters require different contact positions between the pressure roller component 302 and the tire; the design of the mounting holes 2018 allows the operator to select the appropriate hole position for installing the pressure roller body 301 according to the specific tire conditions. This fine-tuning capability ensures that the pressure roller component 302 always contacts the tire at the most suitable angle and force, optimizing the pre-pressure effect and improving the success rate and safety of tire removal.

[0124] Based on the pre-pressure of the tire by the pressure roller component 302, the tire removal hook 4 can smoothly extend into the tire removal opening 9 to separate the outer tire of the tire to be removed 8 from the rim. Since the axis of contact between the pressure roller component 302 and the outer tire of the tire to be removed 8 is perpendicular, excessive compression of the outer tire of the tire to be removed 8 is avoided, achieving efficient and non-destructive tire removal. First, the pressure roller component 302 applies uniform pressure to the surface of the outer tire of the tire to be removed 8, forming the tire removal opening 9, providing an entry point for the tire removal hook 4 to extend; then, the tire removal hook 4 extends into the tire removal opening 9 along the path of the first guide part 7 and the second guide part 6, hooking the connection between the rim and the outer tire of the tire to be removed 8; finally, driven by the tire removal structure 2, the tire removal hook 4 pulls the outer tire of the tire to be removed 8, achieving separation of the outer tire of the tire to be removed 8 from the rim. Throughout the process, since the fourth axis of contact between the pressure roller component 302 and the tire is perpendicular to its own axis of rotation, the tire to be removed 8 is not easily damaged during rotation, ensuring the efficiency and non-destructive nature of the removal process.

[0125] Furthermore, an auxiliary mounting component is provided on the tire removal structure 2 so that the tire removal structure 2 drives the auxiliary mounting component to approach the wheel hub 1001 of the tire to be installed 10 in a preset direction, and makes the auxiliary mounting component adhere to the inner side of the first edge or the second edge of the outer tire 1002 of the tire to be installed 10. When the tire to be installed 10 rotates, the auxiliary mounting component generates a supporting force on the outer tire 1002 to be installed, so that the wheel hub 1001 and the outer tire 1002 to be installed are installed.

[0126] Furthermore, there are two auxiliary mounting components, and the outer tire of the tire to be installed 10 has a first edge and a second edge along its circumference;

[0127] The two auxiliary mounting parts are located on both sides of the tire removal structure 2, and the two auxiliary mounting parts extend in opposite directions. One auxiliary mounting part is used to cooperate with the first edge, and the other auxiliary mounting part is used to cooperate with the second edge.

[0128] Specifically, the tire removal and installation equipment also includes an auxiliary mounting component for installing the tire 10 to be installed. The tire 10 to be installed includes a wheel hub 1001 to be installed and an outer tire 1002 to be installed. The auxiliary mounting component is set on the tire removal structure 2. When the tire 10 to be installed needs to be installed, the tire removal structure 2 drives the auxiliary mounting component to move along a preset direction until the auxiliary mounting component is close to the wheel hub 1001 to be installed and makes the auxiliary mounting component adhere to the inner side of the first edge or the second edge of the outer tire 1002 to be installed. Then the tire 10 to be installed is rotated, and the auxiliary mounting component can generate a supporting force on the outer tire 1002 to be installed, so that the wheel hub 1001 to be installed and the outer tire 1002 to be installed are installed.

[0129] The auxiliary mounting components in this application are two: a first auxiliary component 2014 and a second auxiliary component 2015. The first auxiliary component 2014 is disposed on the first disassembly / assembly part 2011, and the extension direction of the first auxiliary component 2014 is opposite to that of the transmission component 202. A first protective pad 2019 is disposed on the first auxiliary component 2014. Figure 3 As shown, the first auxiliary component 2014 has a hollow interior. The first protective pad 2019 is at least partially disposed within the hollow interior of the first auxiliary component 2014. The second auxiliary component 2015 is disposed on the side of the second disassembly / assembly part 2012 away from the third disassembly / assembly part 2013, and away from the first disassembly / assembly part 2011. The extension direction of the second auxiliary component 2015 is opposite to that of the transmission component 202. A second protective pad 2020 is disposed on the second auxiliary component 2015, with the specific location as shown in the figure. Figure 3As shown, similarly, the interior of the second auxiliary component 2015 is also hollow. At least a portion of the second protective pad 2020 is disposed in the hollow position inside the second auxiliary component 2015. The arrangement of the second auxiliary component 2015 enables the tire bead of the tire to be installed 1002 to be protected when the tire to be installed 10 is installed, so as to prevent the tire bead of the tire to be installed 1002 from contacting the wheel hub 1001 to be installed and causing damage.

[0130] The tire to be installed 10 includes a first edge and a second edge. When the tire to be installed 10 is placed on the rotating support platform, the upper edge is the first edge, and the lower edge is the second edge. The second auxiliary component 2015 is used to cooperate with the first edge. The second auxiliary component 2015 is controlled to fit against the wheel hub 1001 to be installed. Then, the outer tire 1002 to be installed is placed on the wheel hub 1001 to be installed, and the rotating support platform is controlled to rotate. Figure 15 As shown, during the rotation process, and under the action of the second auxiliary component 2015, the second edge is mounted on the wheel hub 1001 to be installed. Then, the tire removal structure 2 is controlled to move away from the second edge, so that the first auxiliary component 2014 fits against the side of the wheel hub 1001 to be installed away from the second edge, and the rotating support platform is controlled to rotate, as shown. Figure 16 As shown, during the rotation of the tire 10 to be installed, and under the action of the first auxiliary component 2014, the first edge is installed on the wheel hub 1001 to be installed, thus completing the installation of the tire 1002 to be installed and the wheel hub 1001 to be installed.

[0131] The auxiliary mounting components are designed to accurately fit the first or second edge of the tire 1002 to be installed. By applying a supporting force to these edges, and in conjunction with the rotation of the rotating support platform, efficient installation of the tire 1002 to be installed onto the wheel rim 1001 is achieved. When the tire 10 is placed on the rotating support platform, the first auxiliary component 2014 and the second auxiliary component 2015 are positioned at the first and second edges of the tire 1002, respectively. As the rotating support platform rotates, these two auxiliary components apply a supporting force to the edges of the tire 1002, causing the edges of the tire 1002 to be installed to fit tightly against the wheel rim 1001, ultimately completing the installation of the tire 10. This process utilizes the positioning capability and supporting force characteristics of the auxiliary mounting components, significantly improving the accuracy and speed of tire installation.

[0132] In use, the second auxiliary component 2015 first controls the installation of the first edge, and then the first auxiliary component 2014 completes the installation of the second edge. This sequential operation ensures the accuracy and integrity of tire installation, avoids misalignment or jamming during the installation process, and improves the quality of tire installation. First, through the cooperation of the second auxiliary component 2015 and the first edge, the first edge of the tire to be installed 1002 is controlled to fit against the wheel hub 1001 to be installed. As the rotating support platform rotates, the second edge is installed onto the wheel hub 1001 under the supporting force. Figure 15 Then, the tire removal structure 2 moves the first auxiliary component 2014 away from the second edge, so that it fits against the other side of the wheel hub 1001 to be installed. Figure 16 During the rotation of the rotating support platform, the first auxiliary component 2014 causes the first edge to be stably mounted on the hub 1001 to be installed.

[0133] The first protective pad 2019, especially when the first auxiliary component 2014 contacts the second edge of the tire 1002 to be installed, reduces friction and vibration, prevents the tire edge from being scratched or worn, and maintains the integrity and appearance of the tire. The first protective pad 2019 is located at the point where the first auxiliary component 2014 contacts the tire. When the first auxiliary component 2014 is in contact with the second edge, the first protective pad 2019 contacts the tire. Its soft or cushioning material absorbs the impact force generated during contact, reducing direct damage to the tire edge and ensuring safety during tire installation and the tire's own integrity.

[0134] The second protective pad 2020 plays a crucial role in the contact process between the second auxiliary component 2015 and the first edge. Similarly, by reducing contact damage, it provides additional safety for tire installation. Combined with the first protective pad 2019, it enhances the overall tire installation experience. Similar to the protective function of the first protective pad 2019, the second protective pad 2020 also provides cushioning and shock absorption when the second auxiliary component 2015 contacts the first edge. When the second auxiliary component 2015 is in contact with the first edge and the second protective pad 2020 is in contact with the tire, its material or structural design prevents damage to the tire edge during installation, ensuring a damage-free and quick tire installation, further improving the user-friendliness and professional performance of the tire installation and removal equipment.

[0135] The rotation of the rotating support platform, combined with the supporting force of the first auxiliary component 2014 and the second auxiliary component 2015, makes the tire installation process smoother and more natural, avoiding the manual adjustment difficulties and installation failure risks that may be encountered in traditional installation methods, thus optimizing the overall tire installation process. With the continuous rotation of the rotating support platform, the first auxiliary component 2014 and the second auxiliary component 2015 alternately act on both sides of the tire edge, promoting the fit between the tire edge and the rim through the application of dynamic supporting force.

[0136] The precise fit of the auxiliary mounting components, combined with the rotation of the rotating support platform, ensures accurate installation of the tire edge onto the rim, improving the precision of tire installation. The inclusion of the first protective pad 2019 and the second protective pad 2020 reduces physical damage to the tire during installation, protecting its lifespan and appearance.

[0137] Furthermore, the tire removal and installation equipment also includes: a first drive structure 1, whose drive unit is drivenly connected to the tire removal hook 4 to drive the tire removal hook 4 to approach the tire removal opening relative to the tire removal structure 2.

[0138] The second drive structure has a drive unit connected to the main body component 205 of the first drive structure 1, so as to drive the first drive structure and the tire removal hook 4 together to move in the direction of the tire 8 to be removed.

[0139] Specifically, such as Figure 1 and Figure 2 As shown, the tire removal and installation equipment also includes a first drive structure 1, which includes a first drive component 101. The drive part of the first drive component 101 is connected to the transmission component 202 to transmit power to the transmission component 202, and then the transmission component 202 transmits the power to the tire removal hook 4, thereby driving the tire removal hook 4 to move. The first drive structure 1 also includes a main sleeve 203 sleeved outside the transmission component 202. The end of the main sleeve 203 away from the first drive component 101 is connected to the tire removal structure 2. For example, a first fixing seat 204 can be provided between the main sleeve 203 and the base of the first drive component 101 by bolts. The main sleeve 203 is directly fixed to the first fixing seat 204 by bolts.

[0140] The second drive structure (not shown in the figure) includes a second drive component. The second drive component and the first drive component 101 are components that can achieve linear drive, such as electric telescopic rods or motors. The drive part of the second drive component is connected to the main body component 205 in the first drive structure 1. The main body component 205 includes a second mounting base 2051 and a bearing component 2052. The second mounting base 2051 is fixed to the drive part of the second drive component by bolts or other means. The bearing component 2052 is fixed to the second mounting base 2051 by bolts or welding. A through hole is provided on the bearing component 2052, through which the main sleeve 203 can pass and be fixedly connected to the bearing component 2052.

[0141] The first driving component 101 serves as the power source, and its stable connection with the transmission component 202 ensures effective power transmission, enabling the tire removal hook 4 to perform the disassembly action precisely and powerfully. The main sleeve 203 not only enhances the stability of the structure but also, through its connection with the first fixed seat 204, ensures the stability and directionality of power transmission, thereby improving the operational accuracy and efficiency of the entire device.

[0142] The main sleeve 203 not only protects the transmission component 202 from external interference, but also ensures the stability of the tire hook 4 during movement through its connection with the first fixed seat 204.

[0143] The introduction of the first fixed seat 204 ensures a firm connection between the main sleeve 203 and the base of the first drive component 101, avoiding the loosening of the power transmission chain under high-intensity working conditions, thereby ensuring the stable operation of the equipment for a long time and improving operational safety and reliability.

[0144] Through reasonable layout and ingenious connection between components, the first drive structure 1 achieves precise control of the movement of the tire hook 4, which not only ensures efficient use of power, but also enhances the overall rigidity and vibration resistance of the equipment through the cooperation of the main sleeve 203 and the first fixed seat 204, making the power output smoother and reducing energy loss and noise generation during the movement process.

[0145] The second drive structure includes a second drive member, which is similar to the first drive member 101 and can achieve linear drive; the main body component 205 includes a second mounting base 2051 and a bearing component 2052, which are fixed by bolts or welding. The bearing component 2052 is provided with a through hole, through which the main sleeve 203 can pass and be fixedly connected to the bearing component 2052.

[0146] The second drive component, acting as an independent power source, is connected to the carrier component 2052 via the second mounting base 2051, ensuring direct and controllable power transmission. The design of the through-hole on the carrier component 2052 allows the main sleeve 203 to connect directly to it, achieving seamless integration between the first drive structure 1 and the second drive structure. This enables flexible switching or coordinated use of the two drive structures during tire removal and installation operations, improving the equipment's versatility and operational flexibility.

[0147] The second guide portion 6 has a length of 100mm, and the distance between the end of the second guide portion 6 away from the first drive structure 1 and the end of the disassembly / assembly body 201 away from the first drive structure 1 is 20mm. The first guide section 701 and the second guide portion 6 are located at... Figure 2 The maximum vertical distance between the second guide section 702 and the second guide part 6 is 50mm, and the minimum vertical distance is 35.5mm. The maximum vertical distance between the second guide section 702 and the second guide part 6 is 35.5mm, and the minimum vertical distance is 21mm. The distance between the end of the first guide section 701 away from the second guide section 702 and the end of the disassembly / assembly body 201 away from the first drive structure 1) is L3, and L3 is 15mm. The length of the first guide section 701 is 20mm. The length of the second guide section 702 is 74.5mm. A first included angle is formed between the first guide section 701 and the second guide section 702. The first included angle is 125°, and the opening of the first included angle is away from the transmission component 202. Figure 14 As shown, the angle between the first guide segment 701 and the horizontal plane where the bottom end of the first guide segment 701 is located is the second angle, which is 15°; the angle between the second guide segment 702 and the horizontal plane where the bottom end of the second guide segment 702 is located is the third angle, which is 110°.

[0148] The precise length and position setting of the second guide part 6 ensures the stability of the tire removal hook 4 during its telescopic movement. Simultaneously, the 20mm distance between it and the end of the tire removal body 201 provides sufficient movement space for the tire removal hook 4, ensuring precise control during tire removal. The length and position of the second guide part 6 directly determine the range and trajectory of the tire removal hook 4. A length of 100mm is sufficient to cover the maximum telescopic distance required for tire removal, while the 20mm spacing ensures that the tire removal hook 4 can extend freely without structural restrictions. Together, these factors achieve precise guidance for the movement of the tire removal hook 4.

[0149] The specific angle settings and length configurations of the first guide section 701 and the second guide section 702 form an optimized motion path, enabling the tire removal hook 4 to smoothly enter the tire removal port 9 according to the specific fit between the tire and the rim. Even with tires with complex structures, efficient removal can be achieved. The 15° second included angle design allows the tire removal hook 4 to initially contact the tire at an oblique angle under the guidance of the first guide section 701, reducing the impact of direct contact and improving operational safety. The 110° third included angle of the second guide section 702 guides the tire removal hook 4 to move along a path that better conforms to the internal contour of the tire after entering the tire removal port 9. The 74.5mm length ensures sufficient travel coverage, and the 125° first included angle ensures a smooth transition of the tire removal hook 4 between the two guide sections. The entire path design takes into account the physical characteristics of the tire, achieving optimization and adaptation of the removal action, and improving operational flexibility and efficiency.

[0150] The change in vertical distance between the first guide section 701 and the second guide section 6 provides a vertical positioning reference for the tire removal hook 4, ensuring vertical position control of the tire removal hook 4 during disassembly and avoiding damage to the tire or equipment due to inaccurate vertical positioning. The maximum distance of 50mm and the minimum distance of 35.5mm allow the tire removal hook 4 to automatically adjust its vertical position according to changes in tire thickness as it moves along the first guide section 701, ensuring vertical accuracy of the disassembly action, reducing operational errors and potential damage, and improving the adaptability and safety of the equipment.

[0151] The vertical distance between the second guide section 702 and the second guide part 6 controls the depth to which the tire removal hook 4 penetrates the tire. A maximum distance of 35.5 mm and a minimum distance of 21 mm ensure that the tire removal hook 4 can penetrate the tire to the appropriate position, achieving separation of the tire from the rim while avoiding potential damage to the tire's internal structure from excessive insertion. The length of the second guide section 702 and the distance between the second guide part 6 together determine the depth and path of the tire removal hook 4 into the tire. This depth control mechanism ensures that the tire removal hook 4 effectively hooks onto the connection between the tire and the rim while avoiding mechanical damage to the inner side of the tire from excessive insertion, ensuring a safe and efficient disassembly process.

[0152] The 15mm distance between the first guide section 701 and the end of the disassembly / removal body 201 is the "preparation zone" before the tire removal hook 4 starts moving along the first guide section 7. This setting takes into account the initial contact requirements between the tire and the tire removal hook 4, ensuring that the tire removal hook 4 can start the disassembly process at the best angle and position, avoiding tire damage or disassembly failure due to improper positioning.

[0153] It is worth noting that during use, the first drive structure 1 can drive the tire removal hook 4 to move towards the tire 8 to be removed, and then the second drive structure can drive the pressure roller structure 3 to form a tire removal opening 9 with the tire 8 to be removed. Alternatively, the tire removal opening 9 can be formed first, and then the first drive structure 1 can drive the tire removal hook 4 to move towards the tire removal opening and enter the tire removal opening 9 to complete the tire removal work. In practical applications, it is generally preferred to form the tire removal opening first, and then transport the tire removal hook 4 to the tire removal opening 9 to complete the tire removal work. When installing the tire 10 to be installed, either the first edge or the second edge can be installed first. In practical applications, it is generally preferred to install the second edge, which is located at the bottom, first, and then install the first edge. This application embodiment does not limit the above operation process.

[0154] The first drive structure 1 offers optional operation procedures: it can either activate the drive to bring the tire removal hook 4 closer to the tire 8 to be removed first, or it can wait until the pressure roller structure 3 has formed the tire removal opening 9 before activating the drive. This ensures operational flexibility, allowing for the selection of the optimal operation sequence based on different scenarios and needs. In actual operation, if removal is required before the tire removal opening 9 has been pre-formed, the first drive structure 1 will activate first, guiding the tire removal hook 4 closer to the tire. However, to improve removal efficiency and reduce tire damage, the generally recommended operation sequence is: first, the pressure roller structure 3 forms the tire removal opening 9, and then the first drive structure 1 drives the tire removal hook 4 into the tire removal opening 9. This flexible design provides operators with more options and improves the adaptability of the equipment.

[0155] The pressure wheel structure 3 pre-compresses the tire, forming a tire removal opening 9. This provides a clear entry point for the tire removal hook 4, simplifying subsequent disassembly steps and protecting the tire from damage. The pressure wheel structure 3 first acts on the tire to form the tire removal opening 9, a crucial step for tire removal. Without this pre-compressed opening 9, the tire removal hook 4 would struggle to accurately insert into the tire-rim connection, increasing the difficulty and potential risks of disassembly.

[0156] First, the pressure roller structure 3 forms the tire removal opening 9, and then the first drive structure 1 drives the tire removal hook 4 to enter. This optimized process design avoids the ineffective operation of the tire removal hook 4 blindly searching for the entry point, improving the efficiency and success rate of tire removal while reducing damage to the tire. The tire removal opening 9 formed by the pressure roller structure 3 provides a clear entry point for the tire removal hook 4, allowing it to directly and quickly extend into the gap between the tire and the rim under the drive of the first drive structure 1, significantly shortening the time of the entire removal process. In addition, the pre-formed tire removal opening 9 also reduces the direct impact of the tire removal hook 4 on the tire, avoiding damage to the tire during the removal process.

[0157] The auxiliary mounting component is designed to allow for installation of either the second edge or the first edge first. This bidirectional installation capability enhances the equipment's versatility, adapts to various tire installation needs, simplifies the installation process, and improves operator efficiency. During the installation of tire 10, the bidirectional installation capability of the auxiliary mounting component means that regardless of which side of the tire is underneath, it can serve as the starting edge for installation. This design avoids unnecessary tire flipping, saving time and effort.

[0158] The flexible design of the equipment's operation process takes into account the different needs in various practical scenarios. Whether it's disassembly or installation, adjustments can be made according to the specific condition of the tire and the operator's preferences, enhancing the equipment's adaptability and user convenience. Combining the above technical features, the tire disassembly and installation equipment of this application demonstrates a highly customized operating mode through the flexible use of the first drive structure 1, the pressure wheel structure 3, and auxiliary installation components. Whether it's the pre-compression operation before disassembly or the edge selection during installation, the equipment offers multiple operational possibilities. This flexible design allows the equipment to better adapt to tires of different sizes and shapes, as well as the operator's personal habits and needs, thus demonstrating high efficiency, safety, and user-friendliness in a wide range of application scenarios.

[0159] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0160] The pressure roller component 302 contacts and pre-presses the outer tire of the tire 8 to be removed, forming the tire removal opening 9. Figure 9 This ensures that the tire removal hook 4 can smoothly and without damage insert between the tire and the rim, avoiding potential tire damage or removal difficulties that might occur if the tire is pried open forcefully using the tire removal hook 4, thus improving removal efficiency and safety. Guided by the first guide section 7 (first guide segment 701 and second guide segment 702) and the second guide section 6, the tire removal hook 4 can move along a preset path when inserting into the tire removal opening 9 and hooking the tire. Figures 6 to 8 This path control not only ensures the stability and accuracy of the tire hook 4's movement, but also avoids excessive compression or damage to the tire, improving the equipment's operating efficiency and adaptability to different tires.

[0161] This flexible design of the operating sequence allows the equipment to adapt to different tire removal needs and scenarios. Figures 9 to 12 For example, for some tires, pre-forming the tire removal opening 9 can simplify the removal process and reduce direct damage to the tire; while directly driving the tire removal hook 4 may be more suitable for situations where the tire and rim are tightly connected. This adjustable operating mode greatly improves the adaptability of the equipment and the convenience of user operation.

[0162] The bidirectional installation capability of the auxiliary mounting components eliminates the need to consider the initial orientation of the tires during installation, simplifying the process and improving operational efficiency. Simultaneously, this flexible design enhances the equipment's adaptability to different tire sizes and types, making tire installation smoother and faster, reducing operational difficulty, and improving the user experience.

[0163] The optimized design of these structural parameters ensures the precision and efficiency of the tire removal hook 4's movement. For example, the variation in the vertical distance between the first guide section 701 and the second guide section 6 (maximum 50mm, minimum 35.5mm) controls the depth to which the tire removal hook 4 enters the tire removal opening 9; the variation in the vertical distance between the second guide section 702 and the second guide section 6 (maximum 35.5mm, minimum 21mm) ensures that the tire removal hook 4 can accurately hook onto the connection between the tire and the rim. This ingenious combination of parameters allows the equipment to achieve optimal performance during disassembly and installation operations, improving the overall accuracy and safety of the operation.

[0164] During tire installation, the use of the first protective pad 2019 and the second protective pad 2020 reduces direct contact between the tire edge and the auxiliary parts, effectively preventing the tire from being scratched or damaged by friction during installation, extending the tire's service life, and improving the aesthetics of the tire installation and user satisfaction.
