Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vehicle parking equipment, and in particular to a roller and a vehicle guiding mechanism. Background Technology
[0002] In the fields of automated parking, battery swapping, or charging, it is often necessary to straighten the vehicle's parking angle when parking, swapping, or charging. Therefore, the system typically includes a vehicle entry guide mechanism, which uses a pair of clamping rods to hold the vehicle and correct its angle. To reduce tire damage during passive vehicle straightening, rollers are usually laid at the vehicle's parking location to reduce tire friction and stress.
[0003] The currently used rollers have bearings at both ends, resulting in very smooth rotation between the outer ring of the roller and the shaft. This makes it easy for people standing on the rollers to fall, posing a serious safety hazard. Therefore, it is necessary to increase the damping of the rollers to reduce the safety risks of the system. Utility Model Content
[0004] In view of the above, it is necessary to provide a built-in damping roller and a vehicle guiding mechanism to improve the rotational damping of the roller.
[0005] Therefore, this disclosure first provides a built-in damping roller, comprising:
[0006] A drum with an internal cavity;
[0007] A mandrel passes through the cavity and is rotatably connected to the roller;
[0008] A friction block is connected to the mandrel, and the friction block contacts the drum when the drum and the mandrel rotate relative to each other.
[0009] According to the built-in damping roller, the friction block includes a through hole and a protrusion, the spindle passes through the through hole and connects to the friction block, and the protrusion abuts against the inner wall of the cavity in the radial direction.
[0010] According to the built-in damping roller, the protrusion extends in the axial direction, and a plurality of the protrusions are distributed in the circumferential direction.
[0011] The built-in damping roller includes a plurality of friction blocks, which are sleeved on the mandrel.
[0012] The built-in damping roller also includes a pair of bearings, which are disposed within the cavity of the roller and connect the roller and the spindle, with the friction block located between the pair of bearings.
[0013] The built-in damping roller also includes a first baffle plate, which is disposed on the outside of the bearing and located between the mandrel and the roller, for sealing the cavity.
[0014] According to the built-in damping roller, the first baffle is a shaft elastic retaining ring that fits onto the mandrel and stops the gap between the mandrel and the roller.
[0015] The built-in damping roller also includes a second baffle plate, which is connected to the spindle and located on both sides of the friction block in the axial direction, for fixing the friction block in the axial direction.
[0016] In addition, this disclosure also provides a vehicle alignment mechanism, characterized in that it includes a front wheel support for supporting the front wheels of the vehicle and a rear wheel support for supporting the rear wheels of the vehicle, wherein at least one of the front wheel support and the rear wheel support is provided with the built-in damping roller.
[0017] The vehicle alignment mechanism further includes a pair of clamping rods, which are movably connected to both sides of the front wheel support and the rear wheel support, for clamping the vehicle and aligning its parking angle when the vehicle is parked at the front wheel support and the rear wheel support.
[0018] Compared to existing technologies, the aforementioned built-in damping roller and vehicle guiding mechanism, by setting a friction block between the spindle and the roller, can apply frictional force to the spindle and roller when the roller rotates between the spindle and the spindle, thereby increasing the damping during the roller's rotation and preventing personnel from being injured by the roller's rotation.
[0019] Furthermore, the aforementioned friction blocks are located inside the cavity of the roller, which can prevent debris and sand from getting trapped. If these get stuck in the roller and come into contact with the friction blocks, it can easily cause wear on both the friction blocks and the roller, reducing their service life. Moreover, debris can easily get stuck in the gap between the roller and the friction blocks, increasing the difficulty of maintenance and cleaning. Attached Figure Description

[0026] The following detailed embodiments will further illustrate this disclosure in conjunction with the above-described drawings. Detailed Implementation
[0027] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this disclosure; the described embodiments are merely a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.
[0029] In various embodiments, for ease of description and not limitation of this disclosure, the term "connection" used in the patent application specification and claims is not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.
[0030] This embodiment first provides a vehicle straightening mechanism, which includes a pair of front wheel supports, a pair of rear wheel supports, and a pair of clamping rods. The front wheel supports support the two front wheels of the vehicle after it is parked. The rear wheel supports support the two rear wheels of the vehicle after it is parked. The pair of clamping rods are movably connected to both sides of the front and rear wheel supports, and are used to clamp the vehicle and straighten its parking angle when it is parked at the front and rear wheel supports. Thus, by providing a traction device for the clamping rods, the pair of clamping rods can move relatively closer or further apart to clamp the front and rear wheels of the vehicle, causing at least one of the front and rear wheels to swing and straighten the vehicle's parking angle.
[0031] During vehicle straightening, the movement of the tires relative to the front and rear wheel supports can cause damage due to friction. Therefore, in some embodiments, a number of built-in damping rollers are installed at at least one of the front and rear wheel supports. Those skilled in the art can install the built-in damping rollers at either the front or rear wheel support as needed, or simultaneously at both; this application does not impose any restrictions on this. Because the friction is high during vehicle straightening, the built-in damping rollers can rotate during the straightening process, reducing damage to the wheels. On the other hand, since the operator's weight is much less than the vehicle's weight, the force exerted on the built-in damping rollers is smaller, making it less likely that stepping on them will cause them to rotate, thus preventing the built-in damping rollers from rolling and causing falls and injuries.
[0032] Figure 1 This is a cross-sectional view of the built-in damping roller. Figure 2 This is an exploded view of a built-in damping roller. (Example) Figure 1 and Figure 2 As shown, the built-in damping roller includes a roller 10, a spindle 20, and a friction block 30. The spindle 20 can be installed on other components, the roller 10 can rotate relative to the spindle 20, and the friction block 30 is used to provide a certain damping for the roller 10 to prevent the roller 10 from rotating randomly and causing the staff to fall.
[0033] The roller 10 is generally cylindrical in shape and has an internal cavity 11. In this embodiment, the roller 10 is a hollow cylindrical structure, and the cavity 11 is a through hole extending through the roller 10 along its length. The mandrel 20 passes through the cavity 11 and is rotatably connected to the roller 10. Specifically, the mandrel 20 is generally rod-shaped, sleeved inside the cavity 11 of the roller 10, and is generally coaxially rotatable with the roller 10. In some embodiments, the mandrel 20 is rotatably connected by bearings 40. Specifically, the built-in damping roller also includes a pair of bearings 40, which are located at the two ends of the roller 10 and the mandrel 20, respectively. The bearings 40 are disposed inside the cavity 11 of the roller 10 and connect the roller 10 and the mandrel 20. The inner ring of the bearing 40 is sleeved on the mandrel 20, and the outer ring is mounted on the inner wall of the cavity 11 of the roller 10. In this way, the roller 10 can rotate relative to the mandrel 20 through the bearings 40. However, those skilled in the art will understand that the roller 10 and the spindle 20 can also be rotatably connected by other components, such as rollers, or by relative sliding.
[0034] To prevent external mud, dust, and moisture from entering the cavity 11, in this embodiment, the built-in damping roller further includes a first baffle 41. The first baffle 41 is disposed outside the bearing 40 and located between the spindle 20 and the roller 10, for sealing the cavity 11. Figure 2As shown, the mandrel 20 has slots 21 at both ends. The first baffle 41 can be a shaft elastic retaining ring, which is fitted into the slots 21 of the mandrel 20 and blocks the gap between the mandrel 20 and the roller 10, thereby sealing the cavity 11 of the roller 10.
[0035] Figure 3 This is a schematic diagram of the friction block 30. (See attached diagram.) Figure 1-3 As shown, the friction block 30 is connected to the spindle 20. When the roller 10 and the spindle 20 rotate relative to each other, the friction block 30 contacts the roller 10. There can be one or more friction blocks 30, with multiple friction blocks 30 sleeved on the spindle 20 and located between a pair of bearings 40. In this way, the friction block 30 is disposed within the sealed cavity 11, which not only saves space for the built-in damping roller but also protects the friction block 30.
[0036] In this embodiment, the friction block 30 extends along the length of the spindle 20, and its cross-section can be a straight line, a cross shape, or a rice-shaped structure. It includes multiple radially protruding portions 32, with recesses 33 between the protruding portions 32. The protruding portions 32 extend axially, and the multiple protruding portions 32 are distributed circumferentially. The protruding portions 32 abut against the inner wall of the cavity 11 in the radial direction. Furthermore, a through hole 34 extending axially is provided at the center of the friction block 30, through which the spindle 20 passes and connects to the friction block 30. During the rotation of the roller 10, the protruding portions 32 abutting against the inner wall of the cavity 11 of the roller 10 can generate friction with the roller 10, and can also generate friction between the inner wall of the through hole 34 and the spindle 20, thereby increasing the rotational damping between the roller 10 and the spindle 20.
[0037] To fix the friction block 30 axially, in this embodiment, the built-in damping roller further includes a second baffle 31. The second baffle 31 is connected to the spindle 20 and located on both sides of the friction block 30 in the axial direction, for fixing the friction block 30 axially. Specifically, the spindle 20 has slots 21 on both sides where the friction block 30 is mounted. The second baffle 31 can be a shaft elastic retaining ring, which is fitted into the slots 21 of the spindle 20 to stop the friction block 30.
[0038] During operation, due to the vehicle's considerable weight, a significant frictional force is applied to the built-in damping roller during the straightening process. This causes the roller to rotate, thus correcting the angle and reducing tire wear and resistance during straightening. However, in other situations, because the worker's weight is relatively small compared to the vehicle, it is difficult to cause the roller 10 to rotate when stepping on it, thereby reducing the risk of falling due to the rotation of the roller 10.
[0039] The aforementioned built-in damping roller and vehicle guiding mechanism, by setting a friction block 30 between the spindle 20 and the roller 10, can apply frictional force to the spindle 20 and the roller 10 when the roller 10 rotates between the spindle 20 and the spindle 20, thereby increasing the damping during the rotation of the roller 10 and preventing personnel from falling and getting injured due to the rotation of the roller 10.
[0040] Furthermore, the aforementioned friction block 30 is disposed inside the cavity 11 inside the roller 10, which can prevent the inclusion of debris and sand. If the debris and sand get stuck in the roller 10 and come into contact with the friction block 30 after the roller 10 rotates, it will easily cause wear on the friction block 30 and the roller 10, reducing the service life. Moreover, debris is easy to get stuck in the gap between the roller 10 and the friction block 30, increasing the difficulty of maintenance and cleaning.
