Description

Technical Field

[0001] This invention relates to the field of vehicle battery swapping, and particularly to a wheel alignment mechanism, a lift, and a battery swapping station. Background Technology

[0002] Electric vehicles, as a new energy mode of transportation, have the characteristics of low noise, high energy efficiency, and zero exhaust emissions, and have become one of the strategic emerging industries that my country focuses on supporting.

[0003] Energy supply is a crucial link in the electric vehicle (EV) industry chain, and the energy supply model is closely related to the development of EVs. Battery swapping models based on battery leasing, combined with large-scale centralized charging, have become competitive factors in the current development of EVs. In existing technologies, battery swapping stations can provide fast battery swapping services for EVs; the more types of EVs a swapping station can accommodate, the higher its utilization rate.

[0004] Currently, battery swapping stations can only locate and swap batteries for vehicles of the same size and specifications, which greatly restricts the utilization rate of the stations. How to make battery swapping stations compatible with vehicles of different sizes and specifications has become a key research and development direction for designers.

[0005] In the prior art, before the battery swapping operation is performed on an electric vehicle, the electric vehicle will drive to the battery swapping station and park on the lift. In order to facilitate the battery swapping equipment to drive from the side of the electric vehicle into the preset position under the electric vehicle and align with the locking mechanism of the electric vehicle, so as to ensure that the battery swapping equipment can be smoothly installed and removed from the electric vehicle, the lift needs to adjust the posture of the electric vehicle so that the locking mechanism of the electric vehicle is aligned with the battery swapping equipment located in the preset position in both the vertical and horizontal directions.

[0006] To improve the compatibility of battery swapping stations, the lift needs to be compatible with different vehicle models. This means that the wheel track adjustment mechanism of the lift needs to be compatible with wheels of different tire widths. However, current lifts are not compatible with different vehicle models. Summary of the Invention

[0007] The present invention addresses the technical problem that existing lifts cannot be adapted to different vehicle models, resulting in low compatibility of battery swapping stations and hindering further improvement. The invention provides a wheel alignment mechanism, a lift, and a battery swapping station.

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A wheel positioning mechanism includes guide rollers arranged at relatively intervals on a lift. Along the wheel width direction, a wheel positioning space for accommodating a wheel is formed between two of the guide rollers. The wheel positioning mechanism also includes a displacement adjustment unit. At least one of the guide rollers is arranged on the lift through the displacement adjustment unit, and the displacement adjustment unit allows the position of the guide roller to be adjusted along the wheel width direction.

[0010] This solution employs a structural form where a displacement adjustment unit controls the distance between the two guide rollers. The wheel positioning space defined by these rollers can accommodate wheels with different tire widths, thus improving the versatility and compatibility of the wheel positioning mechanism. Furthermore, the structure is simple and easy to operate. This enhances the versatility and compatibility of lifts and battery swapping stations equipped with this wheel positioning mechanism.

[0011] Preferably, the displacement adjustment unit includes:

[0012] The connecting part is mounted on the lift;

[0013] Adjustment section, wherein the guide roller is mounted on the adjustment section;

[0014] A limiting part is provided, which is connected to the connecting part and the adjusting part respectively. The limiting part is used to limit the displacement of the adjusting part relative to the connecting part in the wheel width direction.

[0015] In this solution, this structural form is adopted. After the position of the adjusting part relative to the connecting part is adjusted, the position of the adjusting part relative to the connecting part is limited by the limiting part, so that the distance between the two guide rollers can be maintained in a relatively fixed state after adjustment, and the distance between the guide rollers is prevented from changing due to external impact.

[0016] Preferably, the limiting part is a positioning pin, and the adjusting part is provided with at least two first through holes for the positioning pin to pass through, and a plurality of first through holes are arranged at intervals along the wheel width direction.

[0017] The connecting part is provided with a second through hole for the positioning pin to pass through. The positioning pin passes through one of the first through holes and the second through hole in sequence, so that the corresponding guide roller can be in different positions along the wheel width direction.

[0018] In this solution, this structural form is adopted. By setting multiple first through holes on the adjustment part for the positioning pins to pass through, the positioning pins are selected to be inserted into one of them, so as to limit the adjustment part to different positions relative to the connecting part, thereby achieving the purpose of multi-level adjustment.

[0019] Preferably, the limiting part includes a first limiting member and a second limiting member that are threadedly engaged with each other. The first limiting member and the second limiting member are respectively disposed on the connecting part and the adjusting part. The first limiting member can drive the second limiting member to move along the wheel width direction by rotation.

[0020] In this solution, this structural form is adopted, and the stepless displacement adjustment of the adjustment part relative to the connecting part is achieved by the relative rotation of the meshing first limit member and the second limit member, so as to adapt to a variety of wheels with different wheel track and width.

[0021] Preferably, the first limiting member is an adjusting nut rotatably connected to the connecting part, and the adjusting nut is provided with a first thread;

[0022] The second limiting member is an adjusting screw fixedly connected to the adjusting part, and the adjusting screw is provided with a second thread that meshes with the first thread.

[0023] In this solution, the adjusting nut and adjusting screw can be purchased externally, making assembly convenient. Furthermore, the use of adjusting screw and adjusting nut, connected through their cooperation, enhances the reliability of the connection between the two, thereby enabling stable and reliable movement of the adjusting part in the wheel width direction.

[0024] Preferably, the adjusting screw has a second thread on its circumferential outer surface, the adjusting nut has a through hole at its middle position, the adjusting nut rotates around its own axis, the through hole has a first thread on its inner wall, and the adjusting screw passes through the through hole and the two are threadedly connected.

[0025] In this design, this structural form is adopted, in which the first thread and the second thread together form an internal meshing, resulting in a compact structure.

[0026] Preferably, the adjusting nut is at least partially located on the side of the connection portion away from the adjusting portion.

[0027] In this design, this structural form provides space for the user to operate the adjusting nut.

[0028] Preferably, the connecting part is provided with a cylindrical structure extending horizontally in the direction of wheel width, and the adjusting nut part extends into the cylindrical structure and is rotatably connected to the cylindrical structure.

[0029] In this design, this structural form is adopted. By setting up a cylindrical structure, the inner wall of the structure is used to position the adjusting nut, thereby increasing the contact area between the adjusting part and the adjusting nut and improving the structural strength of the rotating connection between the two.

[0030] Preferably, the cylindrical structure is a sliding sleeve arranged in the direction of wheel width.

[0031] In this design, this structural form is adopted to increase the contact area between the adjusting nut and the connecting part, making the positioning and connection between the two more reliable.

[0032] Preferably, the limiting portion further includes an axial limiting structure, which at least partially limits the adjusting nut along the extension direction of the adjusting screw within the cylindrical structure.

[0033] In this solution, this structural form is adopted, and the adjusting nut is at least partially confined within the cylindrical structure by setting an axial limiting structure, so as to prevent the adjusting nut from being displaced relative to the cylindrical structure or from coming out of the cylindrical structure due to external forces.

[0034] Preferably, the axial limiting structure includes a limiting boss disposed on the circumferential surface of the adjusting nut, the limiting boss abutting against the end face of the connecting portion away from the adjusting portion.

[0035] In this design, a limiting boss is provided on one side of the adjusting nut to limit the movement and sliding of the adjusting nut relative to the connecting part, i.e., the cylindrical structure, thereby enhancing the stability of the adjusting nut inside the cylindrical structure.

[0036] Preferably, the axial limiting structure further includes a third limiting member, which is screwed onto the adjusting nut and the cylindrical structure is sandwiched between the limiting boss and the third limiting member.

[0037] In this design, a limiting boss is provided on one side of the adjusting nut, and a third limiting member is provided on the other side of the adjusting nut. By limiting the two sides of the adjusting nut, the movement and sliding of the adjusting nut relative to the connecting part are further prevented, and the stability of the adjusting nut inside the cylindrical structure is enhanced.

[0038] Preferably, the adjusting screw is provided with a fourth limiting member, which abuts against the end face of the adjusting nut away from the third limiting member.

[0039] In this design, this structural form is adopted so that when the screw is subjected to axial impact toward the adjusting nut, the fourth and third limiting members work together to form an integral structure to bear the force, thereby improving the overall structural strength of the adjusting nut.

[0040] Preferably, the adjusting part is slidably connected to the connecting part along the width direction of the wheel via a sliding mechanism.

[0041] In this design, this structural form is adopted, and the sliding mechanism further guides the movement of the adjusting part along the width direction of the wheel.

[0042] Preferably, the sliding mechanism includes:

[0043] A slider is disposed on the upper surface of the connecting part, and a first step is provided on the end face of the slider facing the connecting part. The first step extends from one end of the slider along the width direction of the wheel to the other end of the slider.

[0044] A slide rail is provided on the adjustment part and extends along the width direction of the wheel. The slide rail is provided with a first protrusion that matches the shape of the first step. The first step of the slider presses on the first protrusion.

[0045] In this solution, this structural form is adopted. By setting a slider and a slide rail, at least part of the first protrusion is located on the first step. When the adjusting part moves along the width direction of the wheel, it plays a guiding role for the adjusting part and can limit the displacement of the connecting part along the direction perpendicular to the width direction of the wheel.

[0046] Preferably, the adjustment part further includes a reinforcing structure disposed between the slide rail and the connecting part.

[0047] In this solution, this structural form is adopted. By setting up a reinforcing structure, the connection strength between the slide rail and the connecting part is improved, so as to avoid the slide rail and the connecting part breaking at the connection point due to the force of the wheel hitting the guide roller.

[0048] Preferably, the reinforcing structure is a horizontally arranged reinforcing rib, which is disposed at the connection between the slide rail and the adjusting part.

[0049] In this design, this structural form is adopted, and the stability of the connection between the adjustment part and the connecting part is enhanced by adding reinforcing ribs.

[0050] Preferably, the reinforcing rib is located on the side of the slide rail opposite to the slider.

[0051] In this design, the reinforcing ribs do not affect the guiding and mating of the slide rail and the slider.

[0052] Preferably, the sliding mechanism includes:

[0053] The guide hole provided on the connecting part has its length direction parallel to the wheel width direction;

[0054] A guide rod is connected to the adjustment part, the guide rod passes through the guide waist hole and can reciprocate within the guide waist hole.

[0055] In this design, this structural form is adopted, and the guiding function of the adjustment part is achieved by the cooperation of the guide waist hole and the guide rod.

[0056] Preferably, the sliding mechanism includes one guide hole and two guide rods, the two guide rods being arranged at intervals along the width direction of the wheel.

[0057] In this solution, this structural form is adopted, which makes it less likely for the adjustment part to tip over when passing through the above structure. At the same time, it can reduce problems such as jamming at the sliding connection between the adjustment part and the connecting part and poor movement caused by a single guide rod being subjected to force at a single point.

[0058] Preferably, the adjustment part is connected to the connecting part by two sliding mechanisms, and the two sliding mechanisms are arranged symmetrically at intervals along the length of the vehicle.

[0059] In this design, this structural form provides better guidance and limits the movement of the adjustment part relative to the connecting part in the vehicle's length direction.

[0060] A lift comprising: a wheel positioning mechanism as described in any of the preceding claims;

[0061] A lifting platform, wherein the wheel positioning mechanism is provided on the lifting platform.

[0062] In this solution, this structural form is adopted. By setting the wheel positioning mechanism on the lifting platform of the lift, the lift can be adapted to wheels with different tire widths, thereby improving the compatibility and versatility of the lift.

[0063] Preferably, the wheel positioning mechanism is provided at the positions of the two coaxial wheels on the lifting platform;

[0064] The lift also includes a drive mechanism disposed on the lifting platform, the drive mechanism being connected to at least one set of wheel positioning mechanisms and capable of driving the two sets of wheel positioning mechanisms to adjust the distance along the wheel width direction.

[0065] In this solution, this structural form is adopted. By setting a drive mechanism to adjust the relative distance between the two sets of wheel positioning mechanisms, the lift can be compatible with vehicles with different wheel track and tire width, thereby improving the versatility and compatibility of the lift.

[0066] Preferably, the lift further includes a lifting base and a scissor lift mechanism, the lifting platform being connected to the lifting base via the scissor lift mechanism, and the scissor lift mechanism being used to drive the lifting platform to move up and down relative to the lifting base.

[0067] This design employs a scissor lift mechanism to raise and lower the platform, providing high driving force and stable, reliable lifting, making it suitable for lifting electric vehicles.

[0068] A battery swapping station comprising a lift as described in any of the preceding claims.

[0069] In this solution, the lift can be adapted to wheels with different tire widths and track widths, thereby improving the compatibility and versatility of the battery swapping station and thus increasing its utilization rate.

[0070] The positive and progressive effects of this invention are as follows:

[0071] This wheel alignment mechanism, lift, and battery swapping station achieve the desired distance between two guide rollers by incorporating a displacement adjustment unit. The wheel alignment space defined by these rollers can accommodate wheels with different tire widths, thus improving the versatility and compatibility of the wheel alignment mechanism. Furthermore, the mechanism is simple in structure and easy to operate. This enhances the versatility and compatibility of lifts and battery swapping stations equipped with this wheel alignment mechanism. Attached Figure Description

[0112] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0113]

Example 1

[0114] like Figures 1-2 As shown, Embodiment 1 discloses a lift that is installed in a battery swapping station and is used to lift electric vehicles and adjust their posture.

[0115] Specifically, such as Figure 1 and Figure 3 As shown, the lift 200 includes two wheel alignment mechanisms 100, a lifting platform 201, and a drive mechanism 204. The drive mechanism 204 is connected to one set of wheel alignment mechanisms 100 and can drive the two sets of wheel alignment mechanisms 100 to adjust the distance along the wheel width direction C. Specifically, the fixed end of the drive mechanism 204 is fixedly connected to the lifting platform 201, and a horizontally arranged connecting plate 205 is provided on the power output end of the drive mechanism 204, which rests on the upper surface of the lifting platform 201.

[0116] Among them, a wheel positioning mechanism 100 is provided at the position of each of the two coaxial wheels on the lifting platform 201. The wheel positioning mechanism 100 is set on the connecting plate 205, that is, it is set on the lifting platform 201 through the connecting plate 205.

[0117] In other specific embodiments, the connecting plate 205 can also be disposed on the upper surface of the lifting platform 201 by means of rolling connection or sliding connection; optionally, such as Figure 2 As shown, the lift 200 can also be equipped with two drive mechanisms 204, which respectively drive two sets of wheel positioning mechanisms 100 to adjust their positions along the wheel width direction. This will not be elaborated here.

[0118] To enable the lift 200 to lift electric vehicles, the lift 200 also includes a lifting base 202 and a scissor lift mechanism 203. The lifting platform 201 is connected to the lifting base 202 via the scissor lift mechanism 203. The scissor lift mechanism 203 is used to drive the lifting platform 201 to lift relative to the lifting base 202.

[0119] By adjusting the relative distance between the two sets of wheel alignment mechanisms 100 using the drive mechanism 204, the lift 200 can be compatible with vehicles of different wheelbases, thereby improving its versatility and compatibility, and positioning the vehicle wheels in the positions required for battery swapping. Figures 3-7 As shown, this embodiment provides a preferred structure for a wheel positioning mechanism 100. This wheel positioning mechanism 100 specifically includes two guide rollers 1 spaced apart on the lift 200. The guide rollers 1 are spaced apart along the wheel width direction C, and a wheel positioning space for accommodating the wheel is formed between the two guide rollers 1.

[0120] The wheel positioning mechanism 100 also includes a displacement adjustment unit 2, in which one of the guide rollers 1 is mounted on the lift 200 via the displacement adjustment unit 2. The displacement adjustment unit 2 allows the guide roller 1 to be adjusted in position along the wheel width direction C, thereby changing the distance between the two guide rollers 1 and thus limiting the width of wheels.

[0121] Specifically, in this embodiment, the wheel positioning mechanism 100 includes two parallel guide rollers 1. The guide roller 1 located on the outer side of the lift 200 is directly connected to the connecting plate 205, while the guide roller 1 located on the inner side of the lift 200 is connected to the connecting plate 205 via a displacement adjustment unit 2. That is, both displacement adjustment units 2 are mounted on the lift 200 via the connecting plate 205. The distance between these two guide rollers 1 can be adjusted, and the wheel positioning space defined by them can accommodate wheels with different tire widths, allowing the lift 200 to adapt to wheels with different tire widths. This improves the versatility and compatibility of the wheel positioning mechanism 100, and its simple structure makes it easy to operate. It also improves the versatility and compatibility of the lift 200.

[0122] like Figure 3 As shown, each displacement adjustment unit 2 is provided with a connecting part 21, a limiting part 23 and an adjustment part 22.

[0123] The connecting part 21 is mounted on the lift 200, and the guide roller 1 is mounted on the adjusting part 22, which is used to install and support the guide roller 1. A limiting part 23 is connected to both the connecting part 21 and the adjusting part 22, and limits the displacement of the adjusting part 22 relative to the connecting part 21 along the wheel width direction C. Thus, after the adjusting part 22 is repositioned relative to the connecting part 21, the limiting part 23 restricts the position of the adjusting part 22 relative to the connecting part 21, ensuring that the distance between the two guide rollers 1 remains relatively fixed after adjustment, preventing changes in the distance between the guide rollers 1 due to external impact.

[0124] Specifically, such as Figure 6-7As shown, the limiting part 23 is a positioning pin 24, and the adjusting part 22 has at least two first through holes 221 for the positioning pin 24 to pass through. Multiple first through holes 221 are arranged at intervals along the wheel width direction C. Correspondingly, the connecting part 21 has a second through hole 211 for the positioning pin 24 to pass through. The positioning pin 24 passes through one of the first through holes 221 and the second through hole 211 in sequence, so that the corresponding guide roller 1 can be in different positions along the wheel width direction C. That is, the positioning pin 24 is used to limit the adjusting part 22 to different positions relative to the connecting part 21, achieving multi-level adjustment.

[0125] In this embodiment, as Figure 4 As shown, the adjustment unit 22 includes an adjustment plate 224 and a mounting plate 225 that are horizontally connected to each other. The mounting plate 225 is U-shaped and its opening faces away from the adjustment plate 224. The guide roller 1 is installed at the U-shaped opening of the mounting plate 225.

[0126] The adjustment part 22 is provided with four first through holes 221 for the positioning pin 24 to pass through. The four first through holes 221 are arranged in two rows and two columns, with two first through holes 221 in each row arranged at intervals along the wheel width direction C.

[0127] like Figure 6 and Figure 7 As shown, the connecting part 21 is provided with two second through holes 211, which are spaced apart along the direction C perpendicular to the wheel width. The positions of the second through holes 211 correspond to the positions of the two rows of first through holes 221, thereby realizing a multi-position positioning connection through multiple positioning pins 24, enhancing the stability of the connection between the connecting part 21 and the adjusting part 22, preventing the connecting part 21 from tipping over, and saving processing costs by having fewer second through holes 211.

[0128] In other embodiments, the number and arrangement of the first through hole 221 and the second through hole 211 are not limited and can be set as needed, as long as the positioning pin 24 can achieve the function of adjusting the adjustment part 22 in multiple positions through the first through hole 221 and the second through hole 211.

[0129] In other specific embodiments, the number of first through holes 221 is not limited to this example, but it is necessary to ensure that there are at least two first through holes 221 in each row, and that a second through hole 211 is provided at the corresponding position on the connecting part 21. The purpose of multi-level adjustment can be achieved by inserting the positioning pin 24. For example, there are six first through holes 221 arranged in two rows and three columns or three rows and two columns, and the second through holes 211 are set to two or three respectively. The number of second through holes 211 is consistent with the number of rows of first through holes 221, which will not be elaborated here.

[0130] Furthermore, such as Figure 4 and Figure 6 As shown, both ends of the guide roller 1 are connected to two plate-shaped extensions of the mounting plate 225 extending away from the adjusting plate 224. Specifically, one of the extensions has a circular hole 225a, and the other end has a circular notch structure 225b, that is, a notch is made in the basis of the circular hole.

[0131] The guide roller 1 includes a main body section 11 and a guide section 12 connected in sequence. When installing the guide roller 1, the end of the main body section 11 away from the guide section 12 is first inserted into the circular hole 225a, and then the other end of the main body section 11 is inserted into the circular notch structure 225b through the notch, so that one of the extensions is located between the main body section 11 and the guide section 12, thereby completing the quick positioning and installation of the guide roller 1 and the mounting plate 225.

[0132] The mounting plate 225 adopts the above-mentioned snap-fit ​​mounting structure, which facilitates the installation of the guide roller 1 relative adjustment part 22 by the staff.

[0133] like Figures 4-5 As shown, the wheel positioning mechanism also includes a sliding mechanism 3. The adjusting part 22 is slidably connected to the connecting part 21 along the wheel width direction C through the sliding mechanism 3. This can further realize that the adjusting part 22 can be slidably connected to the connecting part 21 while playing a guiding role.

[0134] like Figure 5 As shown, the sliding mechanism 3 includes a slider 31 and a slide rail 32 that work together.

[0135] Specifically, the slider 31 is disposed on the upper surface of the connecting part 21, and a first step 311 is provided on the end face of the slider 31 facing the connecting part 21. The first step 311 extends from one end of the slider 31 along the wheel width direction C to the other end of the slider 31. At the same time, the slide rail 32 is disposed on the mounting plate of the adjusting part 22, and the slide rail 32 extends along the wheel width direction C. A first protrusion 321 adapted to the first step 311 is provided on the slide rail 32, that is, the shape of the first step 311 matches the shape of the first protrusion 321, so that the first step 311 presses down on the first protrusion 321 from top to bottom. When the adjusting part is displaced relative to the connecting part 21 along the wheel width direction C, the first protrusion 321 moves along the wheel width direction C under the guidance of the first step 311, and is not prone to deviation, thereby realizing the guiding function of the sliding mechanism 3.

[0136] To further improve the connection strength between the slide rail 32 and the connecting part 21, the adjusting part 22 also includes a reinforcing structure 223. In this embodiment, the reinforcing structure 223 is specifically a horizontally arranged reinforcing rib, which is disposed between the slide rail 32 and the connecting part 21, located at the lowest point of the connection between the slide rail 32 and the connecting part 21, and on the side of the slide rail 32 away from the slider 31. This avoids the reinforcing rib affecting the guiding of the slide rail 32 and the slider 31. By providing the reinforcing rib, the force of the wheel hitting the guide roller 1 can be used to prevent the slide rail 32 and the connecting part 21 from breaking at the connection.

[0137] like Figure 4 As shown, in this embodiment, the adjustment part 22 is connected to the connecting part 21 by two sliding mechanisms 3, and the two sliding mechanisms 3 are symmetrically arranged at intervals along the length of the vehicle. The two sliding mechanisms 3 are mirror-symmetrically arranged, meaning that the sliders 31 on both sliding mechanisms 3 are located on the side of the slide rail 32 away from the reinforcing structure 223, so that the slide rails 32 of both sliding mechanisms 3 are located on the side closest to the center of the connecting part 21. This structural form allows the force-bearing area of ​​the adjustment part 22 on the slide rails 32 to be balanced when the adjustment part 22 moves on the two slide rails 32, enhancing the balance and stability of the adjustment part 22's movement on the slide rails 32, and also limiting the movement of the adjustment part 22 relative to the connecting part 21 in the length of the vehicle.

[0138]

Example 2

[0139] like Figures 8-14 As shown, this embodiment discloses another implementation of the wheel positioning mechanism 100. The difference between the wheel positioning mechanism 100 of Embodiment 2 and Embodiment 1 is that the displacement adjustment unit 2 has a different structural form.

[0140] In this embodiment, each displacement adjustment unit 2 is provided with a connecting part 21, a limiting part 23 and an adjustment part 22.

[0141] The connecting part 21 is mounted on the lift 200, the guide roller 1 is mounted on the adjusting part 22, that is, the adjusting part 22 is used to install and support the guide roller 1, and the limiting part 23 is connected to the connecting part 21 and the adjusting part 22 respectively. The limiting part 23 is used to limit the displacement of the adjusting part 22 relative to the connecting part 21 along the wheel width direction C.

[0142] Specifically, such as Figures 8-9 and Figure 12As shown, the limiting part 23 includes a first limiting member 25 and a second limiting member 26 that are threadedly engaged with each other. The first limiting member 25 and the second limiting member 26 are respectively disposed on the connecting part 21 and the adjusting part 22. At the same time, the first limiting member 25 can rotate relative to the adjusting part 22, thereby driving the second limiting member 26 to move along the wheel width direction C, thereby realizing the stepless displacement adjustment of the guide roller 1, which can be adapted to wheels of various widths.

[0143] Preferably, the first limiting member 25 is an adjusting nut, and the second limiting member 26 is an adjusting screw.

[0144] The adjusting nut has a through hole in its center, and the inner wall of this through hole has a first thread. The outer circumferential surface of the adjusting screw has a second thread that meshes with the first thread. The adjusting nut is rotatably connected to the connecting part, allowing it to rotate around its own axis. The end of the adjusting screw away from the adjusting nut is fixedly connected to the adjusting part, while the end of the adjusting screw closer to the adjusting nut passes through the through hole of the adjusting nut, and both are engaged by the first and second threads. Rotating the adjusting nut causes the adjusting screw to move along the wheel width direction C, thereby adjusting the distance between the two guide rollers 1.

[0145] like Figures 12-14 As shown, the outer contour of the adjusting nut projected on the vertical plane is T-shaped, and the smaller end of the adjusting nut extends into the connecting part. That is, the adjusting nut is at least partially located on the side of the connecting part 21 away from the adjusting part 22, which provides sufficient operating space for the user to operate the adjusting nut.

[0146] like Figure 12 As shown, to further reduce the friction between the adjusting nut and the connecting part, a cylindrical structure 222 extending in the wheel width direction C is provided on the connecting part 21. A portion of the adjusting nut extends into the cylindrical structure 222 and fits against the inner wall of the cylindrical structure 222, achieving a rotatable connection between the two. In this embodiment, the cylindrical structure 222 is a sliding sleeve provided in the wheel width direction C.

[0147] The inner wall of the cylindrical structure 222 is used to position the adjusting nut, which increases the contact area between the adjusting part 22 and the adjusting nut, improves the structural strength of the rotating connection and reduces friction.

[0148] like Figures 12-14 As shown, the limiting part 23 also includes an axial limiting structure. The axial limiting structure abuts one end against the cylindrical structure 222 of the connecting part 21, so that the adjusting nut is at least partially confined inside the cylindrical structure 222 in the extending direction of the adjusting screw, and the remaining part of the adjusting nut is located outside the connecting part 21.

[0149] The axial limiting structure includes a limiting boss 251 provided on the circumferential surface of the adjusting nut (see details). Figure 12 and Figure 14 The cylindrical structure 222 includes a limiting boss 251 and a third limiting member 27 screwed onto the adjusting nut. The limiting boss 251 and the third limiting member 27 are located on both sides of the cylindrical structure 222, with the limiting boss 251 abutting against the end face of the connecting part 21 away from the adjusting part 22. By providing a limiting boss 251 on one side of the cylindrical structure 222 and a third limiting member 27 on the other side, the cylindrical structure 222 is limited on both sides, preventing movement and sliding of the cylindrical structure 222 relative to the connecting part 21. This enhances the stability of the adjusting nut inside the cylindrical structure 222 and prevents the adjusting nut from displacing relative to the cylindrical structure 222 or coming out of the cylindrical structure 222.

[0150] Preferably, such as Figures 12-13 As shown, the adjusting screw is provided with a fourth limiting member 28, which abuts against the end face of the adjusting nut away from the third limiting member 27. When the adjusting screw is subjected to an axial impact towards the adjusting nut, the fourth limiting member 28 and the third limiting member 27 work together to form a unified structure on the adjusting nut, improving the overall structural strength of the adjusting nut installed in the connecting part 21. Figures 10-11 As shown, the sliding mechanism 3 includes a guide hole 33 and two guide rods 34 disposed on the connecting part 21. The guide hole 33 is disposed parallel to the wheel width direction C, and the guide rods 34 are spaced apart along the wheel width direction C. The guide rods 34 pass through the guide hole 33 and reciprocate along the length of the guide hole 33. In this embodiment, by adding the guide hole 33, it not only connects the adjusting part 22 and the connecting part 21, but also guides the movement of the adjusting part 22. At the same time, with the above structure, the adjusting part 22 is less likely to tip over, and it can reduce problems such as jamming and unsmooth movement at the sliding connection between the adjusting part 22 and the connecting part 21 caused by a single guide rod 34 being subjected to force at a single point.
