As shown in fig. 8 and 9, the wheel bearing mechanism includes two sets of roller mechanisms 3 accommodated in the mounting groove 51, the two sets of roller mechanisms 3 are arranged in a V shape, each set of roller mechanism 3 includes a plurality of rollers 31 sequentially arranged along the vehicle width direction (Y direction in fig. 2), the inclination angle of the roller 31 relative to the horizontal plane is adjustable, and as shown in fig. 6, the axial direction of the roller 31 is perpendicular to the vehicle width direction, so that the roller 31 can roll when the wheel performs the wheel pitch adjustment, the resistance received when the wheel moves is reduced, and the wear of the roller 31 and the wheel is reduced, thereby improving the service life and the user experience of the lifting device.

Specifically, as shown in fig. 8, the two sets of roller mechanisms 3 are completely accommodated in the mounting groove 51, i.e., the highest point of the roller mechanisms 3 is flush with the upper end of the mounting groove 51. Because the running roller 31 of two sets of running roller mechanisms 3 extends towards the direction of keeping away from each other from bottom to top, running roller 31 is the outside slope of orientation framework 21 from bottom to top promptly, consequently set up the mounting groove 51 that is used for holding running roller mechanism 3 on mounting bracket 5, can make the vehicle at the in-process that removes the running roller mechanism 3 to the mounting groove 51, the wheel can not receive stopping of running roller 31, make the vehicle travel more smoothly, and can also reduce the impact damage of wheel to running roller 31, improve the life of running roller mechanism 3.

In other alternative embodiments, the roller mechanism 3 may not be completely accommodated in the mounting groove 51, but is slightly higher than the upper end of the mounting groove 51, which will not be described herein.

Each group of roller mechanisms 3 further comprises a roller mounting plate 32, a plurality of rollers 31 are rotatably mounted on the roller mounting plate 32, the roller mounting plates 32 play roles of positioning and supporting the rollers 31, and the rollers 31 can rotate around the axes of the rollers 31 relative to the roller mounting plates 32. The two sets of roller mechanisms 3 are arranged oppositely along the running direction of the vehicle, the rollers 31 of the two sets of roller mechanisms 3 extend from bottom to top along the running direction of the vehicle towards the direction far away from each other, the inclination angles of the rollers 31 in the two sets of roller mechanisms 3 are the same, the projections of the two sets of roller mechanisms 3 on the projection surface are V-shaped, and the projection surface is perpendicular to the horizontal plane and parallel to the running direction of the vehicle. A concave space is formed between the two groups of roller mechanisms 3, when the wheel bearing mechanism bears the wheel, part of the wheel is accommodated in the concave space, and the two sides of the wheel along the running direction of the vehicle are respectively abutted against the outer surfaces of the rollers 31 of the two groups of roller mechanisms 3 so as to limit the front and back movement of the wheel in the running direction of the vehicle.

As shown in fig. 4 to 7, the front lift device 13 further includes a track adjusting mechanism provided on the frame body 21. As shown in fig. 4 and 10, the track adjusting mechanism includes a driving portion 4 and two pushing portions 7, the driving portion 4 is connected to the two pushing portions 7, the driving portion 4 is configured to drive the two pushing portions 7 to move in a direction away from each other along the vehicle width direction, so that the two pushing portions 7 are respectively abutted to one of the two coaxial wheels and push the two coaxial wheels to move synchronously along the vehicle width direction, and the centers of the pushing portions 7 are located on the symmetry planes of the two sets of roller mechanisms 3 on the corresponding sides.

Specifically, both the pushing portions 7 are disposed between the two coaxial wheels, that is, both the pushing portions 7 are disposed at the first wheel placing portion 211 and the second wheel placing portion 212. When the electric automobile stops on the front lifting device 13, the two pushing portions 7 are located between the two front wheels, the pushing portions 7 can push the wheels from the inner sides of the two wheels, and compared with the situation that the wheels are pushed from the outer sides of the wheels, the space between the two wheels is fully utilized, so that the lifting device is more compact in structure, and the occupied space is smaller.

The driving portion 4 is connected to the pushing portions 7, and is configured to drive the two pushing portions 7 to move in the vehicle width direction synchronously toward the first wheel placing portion 211 and the second wheel placing portion 212, respectively, and to move in the vehicle width direction by driving the pushing portions 7, so that the pushing portions 7 abut against the wheels on the corresponding sides, and further push the wheels to move in the vehicle width direction. Because the two sets of roller mechanisms 3 have the same inclination angle and are V-shaped, the center of the pushing part 7 in this embodiment is located on the symmetry plane of the two sets of roller mechanisms 3, and the center of the wheel is also located on the symmetry plane of the two sets of roller mechanisms 3, wherein the symmetry plane of the two sets of roller mechanisms 3 is perpendicular to the horizontal plane and parallel to the width direction of the vehicle. The center of pushing part 7 is aligned with the symmetrical surfaces of the two sets of roller mechanisms 3, so that the center of the pushing part 7 can be aligned with the center of the wheel more accurately, the wheel is stressed more uniformly, the wheel is prevented from inclining in the moving process, and the wheel track adjusting precision is improved.

Because the vehicle of different models probably has the wheel of unidimensional not, through setting up two sets of running roller mechanisms and become angle adjustable V type structure for the intermediate position of the wheel of no matter what kind of size all is in the middle zone of two sets of running roller mechanisms, and the central zone of the push portion of track adjustment mechanism is located between two sets of running roller mechanisms, and what make the push portion supported all the time at the in-process that the track was adjusted is the middle zone of wheel.

In other alternative embodiments, it is also possible that the central area of the pushing portion 7 is located between the two sets of roller mechanisms 3, wherein the central area of the pushing portion 7 may also refer to a space around the center of the pushing portion 7 in addition to the center of the pushing portion 7, and the center of the pushing portion 7 is the center of the aforementioned pushing portion 7, and a technician may adjust the central area according to actual conditions, but should ensure that the wheels are uniformly stressed in the process of being pushed by the pushing portion 7 as much as possible; the inclination angles of the rollers 31 in the two sets of roller mechanisms 3 can also be different, and the design can be specifically carried out according to actual conditions, so that the thrust which the wheels receive when the wheel track is adjusted needs to be ensured to be equal to the force required by the rotation of the rollers 31, and the description is omitted here.

Specifically, as shown in fig. 10, the first avoidance portion in the present embodiment is the avoidance slope 71 on both sides of the lower portion of the pushing portion 7, and as shown on both sides of the pushing portion 7 in the vehicle traveling direction in fig. 4, the two avoidance slopes 71 extend from bottom to top in the vehicle traveling direction toward directions away from each other, that is, the inclined direction of the avoidance slope 71 corresponds to the inclined direction of the roller mechanism 3, so as to reduce the possibility of interference between the pushing portion 7 and the roller mechanism 3. The embodiment directly processes the avoidance inclined surface 71 on the pushing part 7 to form the first avoidance part, and has simple structure and easy processing.

As shown in fig. 11, the lower end of the roller mechanism 3 is rotatably connected to the mounting frame 5 of the frame body 21 through a rotating mechanism 61, and the wheel bearing mechanism further includes an angle adjusting assembly, which is disposed between the roller mechanism 3 and the mounting frame 5 of the frame body 21 and is used for adjusting an inclination angle of the roller mechanism 3 relative to a horizontal plane.

The angle adjusting assembly can change the included angle between the roller mechanism 3 and the frame body 21 according to actual requirements, and further realize the inclination angle adjustment of the roller 31, so that the roller 31 can be adapted to wheels of more sizes.

Specifically, as shown in fig. 11 to 13, the rotating mechanism 61 includes two first ear plates 611, two sets of second ear plates 612 and a rotating shaft 613, the roller mechanism 3 further includes an adjusting plate 33, the roller mounting plate 32 is detachably fixed on the adjusting plate 33 by a bolt, the adjusting plate 33 is rotatably connected to the mounting frame 5 of the frame body 21 by the rotating mechanism 61, and the roller mounting plate 32 is prevented from being directly hinged to the frame body 21. The axes of the plurality of rollers 31 in the roller mechanism 3 are parallel to each other and perpendicular to the rotation axis of the rotation mechanism 61. The two first lug plates 611 are attached to the adjustment plate 33 and located at one end of the adjustment plate 33 near the bottom of the attachment groove 51 (the lower end of the adjustment plate 33 in fig. 13), and the two first lug plates 611 are located at both ends of the adjustment plate 33 (the left and right ends of the adjustment plate 33 in fig. 9), respectively, in the vehicle width direction. Two sets of second otic placodes 612 are installed on the tank bottom of mounting groove 51 and are corresponding the setting with two first otic placodes 611 respectively, and first otic placode 611 and two corresponding second otic placodes 612 of the same set rotate through axis of rotation 613 and are connected, and above-mentioned structure can provide stable support for running roller mechanism 3.

In other alternative embodiments, there may be only one second ear plate 612 in each set of second ear plates 612, as long as the first ear plate 611 and the corresponding second ear plate 612 are rotatably connected by the rotating shaft 613; if the adjusting plate 33 is not disposed in this embodiment, the first ear plate 611 is disposed at an end of the roller mounting plate 32 close to the bottom of the mounting groove 51, so that the roller mechanism 3 can rotate relative to the frame body 21, which is not described herein again.

Since the larger the inclination angle of the roller mechanism 3 with respect to the horizontal plane is, the closer the distance between the upper ends of the two sets of roller mechanisms 3 in the vehicle traveling direction is, and since the push portion 7 is located between the two sets of roller mechanisms 3, when the inclination angle of the roller mechanism 3 with respect to the horizontal plane is the largest, the closer the distance between the upper end of the roller mechanism 3 and the push portion 7 is, the more easily the interference therebetween is generated. In this embodiment, when the inclination of running roller mechanism 3 for the horizontal plane is the maximum value, the angle adjusting part is in first extreme position, and pushing part 7 has the certain distance with running roller mechanism 3 to guarantee that pushing part 7 and running roller mechanism 3 do not produce the interference all the time.

[ example 3 ]

Embodiment 3 discloses another specific implementation of a multi-vehicle type lifting device convenient for adjusting the wheel track, and the specific structure of the angle adjusting assembly is further optimized on the basis of embodiment 3 and embodiment 2.

As shown in fig. 11 and 13, the angle adjusting assembly includes a guiding subassembly 62 and a limiting subassembly 63, the guiding subassembly 62 includes a moving part and a guiding part which are matched with each other, the guiding part is disposed on the frame body 21, and the moving part is slidably connected with the roller mechanism 3 through a rotating block 623. The moving portion moves on the frame body 21 in the vehicle traveling direction under the guidance of the guide portion. The stop subassembly 63 serves to define the relative position of the moving part on the guide part. The sliding connection between the moving part and the roller mechanism 3 means that the moving part and the roller mechanism 3 can slide relatively, but the moving part and the roller mechanism 3 cannot be separated from each other when sliding relatively.

In this embodiment, the moving portion drives the rotating block 623 to move synchronously along the vehicle traveling direction in the process of moving along the vehicle traveling direction, and the rotating block 623 also rotates relative to the moving portion under the action of the downward pressure of the roller mechanism 3, so that the relative positions of the rotating block 623 and the roller mechanism 3 are changed, and the angle between the roller mechanism 3 and the frame body 21 is changed.

The bottom of the first sliding block 622 has a first sliding slot 6221, and the first sliding block 622 slides in cooperation with the first sliding rail 621 through the first sliding slot 6221. The end of the first slider 622 away from the frame body 21 is provided with an inclined surface 6222, the inclined direction of the inclined surface 6222 is the same as the inclined direction of the roller mechanism 3, in this embodiment, the inclined direction of the inclined surface 6222 is the same as the inclined direction of the roller mechanism 3, which means that the inclined surfaces 6222 are the same as the inclined direction of the roller mechanism 3, and do not represent the same inclined angle. The inclined plane 6222 is provided with a groove 6223 which is recessed downwards, a rotating block 623 is hinged in the groove 6223, and part of the rotating block 623 extends out of the groove 6223 and is connected with the roller mechanism 3 in a sliding way.

The sliding rail 621 is used for guiding the moving direction of the first slider 622, so as to prevent the first slider 622 from shifting in the moving process, and the first slider 622 can drive the rotating block 623 to synchronously move along the vehicle moving direction in the moving process along the vehicle moving direction, and the rotating block 623 can also rotate relative to the first slider 622 under the action of downward pressure of the roller mechanism 3, so that the relative positions of the rotating block 623 and the roller mechanism 3 are changed, and the angle between the roller mechanism 3 and the frame body 21 is changed. The rotating block 623 is hinged to the first slider 622, so that the rotating block 623 can perform adaptive angle adjustment according to the inclination angle of the roller mechanism 3, the rotating block 623 and the roller mechanism 3 are always in a surface contact state, and the rotating block 623 can provide stable support for the roller mechanism 3. The first sliding block 622 is provided with a groove 6223, and the partial rotating block 623 is hinged inside the groove 6223, so that the space inside the first sliding block 622 is fully utilized, the size of the moving part in the height direction of the vehicle is shortened, and the whole structure is more compact.

In this embodiment, one surface of the rotating block 623 facing the roller mechanism 3 is a plane, one surface of the adjusting plate 33 facing the rotating block 623 is also a plane, the rotating block 623 and the adjusting plate 33 slide in direct contact, the first slider 622 has a certain limiting effect on the rotating block 623, the rotating block 623 is prevented from moving in the vehicle width direction, and the possibility of deviation when the rotating block 623 and the roller mechanism 3 slide relatively is reduced.

In other alternative embodiments, a guide mechanism may be disposed between the rotating block 623 and the roller mechanism 3 to guide the sliding direction of the rotating block 623 relative to the roller mechanism 3, so as to further reduce the possibility of offset when the rotating block 623 and the roller mechanism 3 slide relatively, and the guide mechanism may be a linear guide mechanism such as a sliding rail slider, a rack and pinion, etc.; the rotating block 623 and the roller mechanism 3 may not be in sliding connection, and the rotating block 623 and the roller mechanism 3 may simply abut against each other, that is, a part of the rotating block 623 extends out of the groove 6223 and abuts against the roller mechanism 3, which is not described herein again.

As shown in fig. 13 and 14, when the angular adjustment assembly is in the first extreme position, the rotary block 623 abuts against the first side notch 6224 of the groove 6223 (the right side notch of the groove 6223 in fig. 14). When the inclination angle of the roller mechanism 3 with respect to the horizontal plane is at a minimum, the angle adjustment assembly is at the second limit position, and the rotating block 623 abuts against the second side notch 6225 of the groove 6223 (the left side notch of the groove 6223 in fig. 14). Wherein the distance between the second side notch 6225 of the groove 6223 and the roller mechanism 3 in the vehicle traveling direction is larger than the distance between the first side notch 6224 of the groove 6223 and the roller mechanism 3 in the vehicle traveling direction. The first side notch 6224 and the second side notch 6225 of the groove 6223 are used for limiting the rotation range of the rotation block 623, preventing the rotation block 623 from rotating excessively, and ensuring that the rotation block 623 can be always connected with the roller mechanism 3.

As shown in fig. 11, the frame body 21 includes a side plate 52 vertically disposed, the side plate 52 is a side wall of the mounting frame 5 corresponding to the mounting groove 51, the limiting subassembly 63 includes an adjusting nut 632 and an adjusting rod 631, the adjusting nut 632 is fixedly disposed on the side plate 52, and the adjusting rod 631 abuts against the first slider 622 after passing through the adjusting nut 632 and the side plate 52 in sequence, so as to apply an acting force to the first slider 622 along the vehicle traveling direction. The adjustment rod 631 is screw-coupled with the adjustment nut 632. In the embodiment, the first slider 622 is driven to move by the movement of the adjusting rod 631 relative to the side plate 52, so as to adjust the included angle between the roller mechanism 3 and the frame body 21, and the threaded connection between the adjusting rod 631 and the adjusting nut 632 can limit the movement of the adjusting rod 631 along the axial direction thereof when the roller mechanism 3 is not required to be adjusted, so as to prevent the first slider 622 from continuously moving relative to the first sliding rail 621.

Specifically, the side plate 52 has a through hole, the adjusting nut 632 is fixed on the side plate 52, and the adjusting nut 632 is coaxially disposed with the through hole on the side plate 52. The adjusting rod 631 in this embodiment is a bolt, and the adjusting rod 631 is screwed to the side plate 52 through an adjusting nut 632. During adjustment, the adjusting rod 631 is rotated to axially move the adjusting rod 631 relative to the adjusting nut 632, so as to drive the first sliding block 622 to move on the first sliding rail 621. In the embodiment, the adjusting nut 632 is arranged on the side plate 52, so that a threaded hole is not processed on the side plate 52, and the production cost is reduced.

In this embodiment, the angle adjustment subassembly that every group running roller mechanism 3 corresponds has two sets ofly, includes two direction subassemblies 62 and two spacing subassemblies 63 promptly, and two direction subassemblies 62 and two spacing subassemblies 63 set up the both ends at running roller mechanism 3 along vehicle width direction, improve the supporting effect to running roller mechanism 3, guarantee that running roller mechanism 3 atress is even when carrying out angle adjustment.

When the inclination angle of the roller mechanism 3 needs to be adjusted to be small, the adjusting rod 631 is driven to move towards the outside of the mounting groove 51 in the vehicle driving direction, the adjusting rod 631 is separated from the first slider 622, the first slider 622 is not supported by the adjusting rod 631, the limiting effect on the roller mechanism 3 is limited, the roller mechanism 3 falls under the influence of gravity, and the first slider 622 is driven to move towards the outside of the mounting groove 51 in the vehicle driving direction until the first slider 622 abuts against the adjusting rod 631.
