Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a vehicle anti-skid roller, a wheel positioning device for a battery swapping station, and a battery swapping platform. Background Technology

[0002] Existing battery swapping stations frequently experience wheel slippage during rain and snow, preventing vehicles from leaving the platform and severely impacting swapping efficiency and user experience. To address this issue, one solution involves installing anti-slip rollers on the swapping platform. These rollers provide space for the wheels, allowing them to contact the rollers as the vehicle leaves the platform and clear rain and snow. However, these anti-slip rollers generally suffer from insufficient friction, poor drainage, and low durability. Summary of the Invention

[0003] This utility model provides a vehicle anti-slip roller with good drainage effect and durability, including a cylinder body, on which an anti-slip unit is provided. The anti-slip unit is used to scrape rain and snow off the wheel. The anti-slip unit includes a drainage groove recessed on the surface of the cylinder body. A first side of the drainage groove and the cylinder body form a first step portion, and a second side of the drainage groove and the cylinder body form a second step portion. The anti-slip unit contacts the wheel through the first step portion and the second step portion.

[0004] Furthermore, the anti-slip unit also includes a drainage profile, which is disposed on the surface of the cylinder. The drainage profile is disposed on both the first and second sides of the drainage groove. The drainage profile and the drainage groove form the first step and the second step. The drainage profile is provided with knurling, which is used to contact the wheel.

[0005] Furthermore, the drainage groove includes a first surface, a second surface, and a third surface, which are sequentially connected to form the drainage groove. The first surface and the second surface are located on the first side and the second side of the drainage groove, respectively, and the third surface is located at the bottom of the drainage groove.

[0006] Furthermore, the drainage surface and the first surface are arranged vertically to form the first step portion, and the drainage surface and the second surface are arranged vertically to form the second step portion.

[0007] Furthermore, the first and third surfaces are arranged vertically, as are the second and third surfaces.

[0008] Furthermore, it also includes a roller shaft and an elastic part. The roller shaft is disposed in the cylinder along the axial direction of the vehicle anti-slip roller, and the elastic part is disposed in the cylinder. The cylinder can slide relative to the roller shaft, and the elastic part is used to reset the cylinder after sliding relative to the roller shaft.

[0009] Furthermore, it also includes a bearing section, which is connected to the roller shaft and the cylinder body respectively, and the cylinder body rotates relative to the roller shaft through the bearing section.

[0010] Furthermore, it also includes a dust cover, which is disposed at the front end and rear end of the vehicle anti-slip roller in the axial direction. The dust cover is used to protect the elastic part and the bearing part inside the roller.

[0011] Furthermore, this utility model also includes a wheel positioning device for a battery swapping station, which includes the aforementioned anti-skid rollers for vehicles. The wheel positioning device for the battery swapping station includes a plurality of anti-skid rollers arranged side by side, and the axial direction of the anti-skid rollers is consistent with the length direction of the vehicle.

[0012] Furthermore, the present invention also includes a battery swapping platform, which includes the aforementioned vehicle anti-slip roller, and the battery swapping platform also includes a sewage collection device for collecting rain and snow scraped off by the anti-slip unit.

[0013] The anti-slip roller provided by this utility model scrapes away rain and snow from the wheels through the anti-slip unit on the cylinder, making it difficult for a water film to form between the wheels and the cylinder. This avoids the problem of the wheels slipping on the battery swapping platform and being unable to leave the battery swapping station. It has a good drainage effect and is more durable than setting a knurled structure on the cylinder alone, with lower processing cost. Attached Figure Description

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended purpose of the invention, the present utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0019] It should be noted that the terms "first," "second," "third," "fourth," etc., in the specification and claims of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0020] In this manual, the directional terms "X-direction," "Y-direction," and "Z-direction" refer to the "vehicle X-direction," "vehicle Y-direction," and "vehicle Z-direction" commonly used in the automotive industry, respectively. "Vehicle X-direction" refers to the length of the vehicle body, which is also the front-to-back direction; "Vehicle Y-direction" refers to the width of the vehicle body, which is also the left-to-right direction; and "Vehicle Z-direction" refers to the height of the vehicle body, which is also the up-and-down direction.

[0021] Please see Figures 1 to 3 The present invention relates to an anti-skid roller for vehicles, comprising a cylindrical body 1, on which an anti-skid unit 2 for scraping rain and snow off the wheels is provided. The anti-skid unit 2 includes a drainage groove 21 recessed into the surface of the cylindrical body 1. A first side of the drainage groove 21 forms a first step with the cylindrical body 1, and a second side of the drainage groove 21 forms a second step with the cylindrical body 1. The anti-skid unit 2 contacts the wheel through the first and second steps. Specifically, in this embodiment, the cylindrical body 1 is cylindrical, and several drainage grooves 21 are spaced apart along the axial direction of the cylindrical body 1 on its surface. The drainage grooves 21 are annular grooves circumferentially recessed into the cylindrical body 1. The first and second steps are formed on two opposite edges of the drainage grooves 21. The axial direction of the anti-skid roller is consistent with the driving direction of the vehicle, i.e., the X-direction of the vehicle body. When the vehicle enters the battery swapping platform where the anti-skid roller is located, the first and second steps contact different parts of the wheel successively. The anti-slip roller of this utility model scrapes away rain and snow on the wheels through the anti-slip unit 2 on the cylinder 1, making it difficult for a water film to form between the wheels and the cylinder 1. This avoids the problem of the wheels slipping on the battery swapping platform and being unable to leave the battery swapping station. It has a good drainage effect and is more durable than setting a knurled structure on the cylinder 1 alone.

[0022] Furthermore, the anti-slip unit 2 also includes a drainage surface 22, which is disposed on the surface of the cylinder 1. Drainage surfaces 22 are provided on both the first and second sides of the drainage groove 21, forming a first step and a second step with the drainage groove 21. Specifically, in this embodiment, the drainage surface 22 is provided with knurling for contact with the wheel. As is well known to those skilled in the art, knurling is a structure that can increase the surface friction of an object. Providing knurling on the first surface of the cylinder 1 can increase the friction when the cylinder 1 contacts the wheel, strengthening the anti-slip effect of the anti-slip roller. Furthermore, since drainage surfaces 22 are provided on the first and second sides of the drainage groove 21 respectively, when the wheel contacts and rubs against the drainage surface 22, rain and snow that are rubbed off the wheel will naturally fall into the drainage groove 21, thereby preventing the battery swapping platform from being blocked by sewage or rain and snow. The overall drainage effect is good, and it is easy to maintain later.

[0023] Furthermore, the drainage groove 21 includes a first surface 21a, a second surface 21b, and a third surface 21c. The first surface 21a, the second surface 21b, and the third surface 21c are connected in sequence to form the drainage groove 21. The first surface 21a and the second surface 21b are located on the sidewalls of the first and second sides of the drainage groove 21, respectively, and the third surface 21c is located at the bottom of the drainage groove 21. Specifically, in this embodiment, the drainage groove 21 formed by the first surface 21a, the second surface 21b, and the third surface 21c connected in sequence is a rectangular groove, that is, the first surface 21a and the third surface 21c form a right angle, the second surface 21b and the third surface 21c form a right angle, and the cross section of the drainage groove 21 is a rectangle with the opening facing the outside of the cylinder 1; the drainage surface 22 forms a right angle with the first surface 21a and forms a first step, and the drainage surface 22 forms a right angle with the second surface 21b and forms a second step, that is, the first step and the second step are both right angles in cross section. The first step, the second step and the drainage groove 21 configured in this way have extremely low manufacturing cost and high durability. The rain and snow scraped off by the first step and the second step and the rain and snow scraped off by the knurling on the first surface 21a can fall from the wheel into the drainage groove 21, and then fall into the sewage collection device of the battery swapping platform below the vehicle anti-skid roller. This invention uses a drainage groove 21 of a certain depth to temporarily accommodate rain and snow scraped off the wheel, thus preventing rain and snow from accumulating on the wheel surface again after being scraped off the wheel and forming a water film, resulting in good drainage.

[0024] Furthermore, the anti-slip roller of this invention also includes a roller shaft 3 and an elastic part 4. The roller shaft 3 passes through the anti-slip roller along its axial direction and is installed inside the anti-slip roller. The cylinder body 1 is sleeved on the roller shaft 3 and can move relative to the roller shaft 3 along its axial direction. The elastic part 4 is disposed inside the cylinder body 1 and is used to reset the cylinder body 1 after axial movement relative to the roller shaft 3. Even further, the anti-slip roller of this invention also includes a bearing part 5, which is disposed inside the cylinder body 1 and is connected to both the cylinder body 1 and the roller shaft 3. The cylinder body 1 rotates relative to the roller shaft 3 via the bearing part 5. Specifically, in this embodiment, the bearing part 5 includes a ball bearing. The inner ring of the ball bearing is integrally connected to the roller shaft 3, and the outer ring of the ball bearing is integrally connected to the cylinder body 1. The cylinder body 1 and the roller shaft 3 achieve relative rotation through the ball bearing arranged in this way. In a preferred embodiment of this utility model, the front and rear ends of the vehicle anti-slip roller shaft 3 are respectively provided with bearing parts 5, so that the cylinder body 1 and the roller shaft 3 can rotate stably relative to each other. Furthermore, the vehicle anti-slip roller in this utility model also includes a dust cover 6. The dust cover 6 is disposed at the front and rear ends of the vehicle anti-slip roller shaft 3 in the axial direction. The dust cover 6 is used to shield and protect the elastic part 4 and the bearing part 5 inside the cylinder body 1 from the axial direction of the vehicle anti-slip roller. In a preferred embodiment of this utility model, the dust cover 6 is disposed outside the bearing part 5 and covers the bearing part 5. By shielding the elastic part 4 and the bearing part 5 inside the cylinder body 1 from the front and rear ends of the vehicle anti-slip roller shaft 3 in the axial direction, the service life of the vehicle anti-slip roller is improved. Specifically, in this embodiment, the roller shaft 3 is located on the central axis of the vehicle anti-skid roller, and the elastic part 4 is a spring sleeved on the roller shaft 3. When the wheel comes into contact with the vehicle anti-skid roller, the wheel rotation will drive the cylinder 1 to rotate along the roller shaft 3, and at the same time, it will push the cylinder 1 along the axial direction of the vehicle anti-skid roller, so that the cylinder 1 and the roller shaft 3 move relative to each other in the axial direction. At this time, the anti-skid unit 2 on the cylinder 1 contacts the wheel and scrapes away the rain and snow on the wheel. When the wheel is separated from the vehicle anti-skid roller, the cylinder 1 is reset under the elastic action of the elastic part 4.

[0025] Furthermore, this utility model also includes a wheel positioning device for a battery swapping station, which includes several of the aforementioned anti-skid rollers arranged in groups side by side, wherein the axial direction of the anti-skid rollers is consistent with the length direction of the vehicle, i.e., the X-direction of the vehicle body.

[0026] Furthermore, this utility model also includes a battery swapping platform, which includes several of the aforementioned vehicle anti-slip rollers arranged in groups side by side, and a sewage collection device disposed below the vehicle anti-slip rollers. Rain and snow scraped off by the vehicle anti-slip rollers will fall into the anti-slip unit 2 inside the sewage collection device along the drainage groove 21 under the action of gravity. The sewage collection device can collect sewage and discharge it uniformly.

[0027] In summary, the vehicle anti-slip roller of this utility model scrapes away rain and snow from the wheels through the anti-slip unit on the cylinder, making it difficult for a water film to form between the wheels and the cylinder, thus avoiding the problem of the wheels slipping on the battery swapping platform and being unable to leave the battery swapping station. It has a good drainage effect and is more durable than setting a knurled structure on the cylinder alone, with lower processing costs.

[0028] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
