Description

Technical Field

[0001] The present invention relates to a wheel limiting device, a lifting machine and a battery swapping station. Background Art

[0002] Electric vehicles have the advantages of zero emissions, low noise, and being very economical in operation and maintenance, and are increasingly favored by users. The energy used by electric vehicles is the electric energy provided by the on-board power battery pack, and electric vehicles need to be charged after the electric energy is used up. Due to the limitations of existing battery technology and charging technology, it takes a long time to fully charge an electric vehicle, which is not as simple and fast as directly refueling a fuel vehicle. Therefore, in order to reduce the waiting time of users, replacing the battery when the electric energy of the electric vehicle is almost exhausted is an effective means. In order to facilitate the replacement of the battery of the electric vehicle and meet the battery swapping needs of the electric vehicle, it is necessary to build a battery swapping station. With the rapid popularization of electric vehicles, more battery swapping stations need to be built to meet the demand.

[0003] Existing battery swapping stations are all provided with a battery swapping room, and a lifting machine is arranged in the battery swapping room. The lifting machine is used to lift the battery swapping vehicle to facilitate the fast battery swapping operation. A wheel limiting device is arranged on the lifting machine. The wheel limiting device includes a roller, and the roller is installed on the mounting seat. Since the roller bears the wheel, when the wheel passes over the roller, dust or muddy water often falls, and the dust or muddy water will flow through the roller to the inside of the mounting seat below, which is not convenient for cleaning. Especially in cold regions, the battery swapping vehicle will bring snow into the mounting seat. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that the wheel limiting device in the prior art is not convenient for cleaning the muddy water and dust brought by the vehicle and collected on the mounting seat, and to provide a wheel limiting device, a lifting machine and a battery swapping station.

[0005] The present invention solves the above technical problem by the following technical solutions:

[0006] A wheel limiting device is arranged on a lifting machine in a battery swapping station and is used to limit the wheels of a battery swapping vehicle. The wheel limiting device includes a mounting seat and a limiting mechanism. The mounting seat has a receiving cavity with an upper opening, and the limiting mechanism is installed in the receiving cavity. The bottom of the receiving cavity has a sewage discharge port that penetrates up and down, so that the dirt falling from the wheels of the battery swapping vehicle passes through the limiting mechanism and is discharged to the outside of the wheel limiting device through the sewage discharge port.

[0007] In this solution, when the battery-swapping vehicle drives into the wheel limiting device, some dirt (sand grains, dust, snow or sewage) attached to the tire surface will be brought into the wheel limiting device. To ensure the normal use of the wheel limiting device, a sewage outlet is provided at the bottom of the receiving cavity of the mounting seat, so that the dirt brought onto the wheel limiting device by the tire falls from the tire into the lower receiving cavity and then is discharged through the sewage outlet of the receiving cavity, preventing sewage, dust and melted snow from accumulating at the bottom of the mounting seat and affecting the normal use of the wheel limiting device.

[0008] Preferably, the limiting mechanism includes a plurality of rollers, and the plurality of rollers are divided into two rows and are installed on the mounting seat at intervals to form a downwardly concave V-shaped groove structure.

[0009] The sewage outlet includes a first sewage outlet, and the first sewage outlet is provided below each row of the rollers.

[0010] In this solution, when the battery-swapping vehicle stops on the V-shaped groove structure, it can automatically center by gravity. The first sewage outlet is provided below each row of rollers, improving the sewage discharge effect.

[0011] Preferably, the projection of each row of the rollers in the vertical direction is located inside the first sewage outlet.

[0012] In this solution, with the above structure, the dirt falling off the wheel can fall into the first sewage outlet after passing through the rollers, improving the sewage discharge effect.

[0013] Preferably, the mounting seat has two side plates for mounting the limiting mechanism and a bottom plate for fixing the two side plates below the limiting mechanism. Two first sewage outlets are formed by hollowing out the bottom plate, and a reinforcing plate is provided in the interval area corresponding to the two rows of rollers, and the first sewage outlets are formed on both sides of the reinforcing plate.

[0014] In this solution, with the above structure, the strength of the mounting seat is ensured by setting the reinforcing plate, and the first sewage outlets are provided on both sides of the reinforcing plate corresponding to the two rows of rollers one by one, improving the sewage discharge effect. At the same time, through the hollow design, two first sewage outlets and the reinforcing plate are directly formed, facilitating the processing and production of the mounting seat.

[0015] Preferably, the sewage outlet further includes a second sewage outlet provided on the reinforcing plate.

[0016] In this solution, the second sewage outlet is provided to discharge the dirt falling from the interval between the two rows of rollers, improving the sewage discharge effect.

[0017] Preferably, the number of the second sewage outlets is multiple, and the multiple second sewage outlets are arranged at intervals along the length direction of the reinforcing plate.

[0018] In this solution, with the above structure setting, the sewage discharge effect is improved.

[0019] A lift, the lift includes a base and a lifting platform, and the two ends of the lifting platform are respectively provided with the wheel limiting devices as described above.

[0020] In this solution, the lifting platform is installed on the base and can lift relative to the base. The two wheel limiting devices on the lifting platform are respectively used for limiting and fixing the left and right wheels at one end of the battery swapping vehicle.

[0021] Preferably, a receiving cavity for receiving dirt is provided on the base, and the sewage discharge port and the receiving cavity are correspondingly arranged.

[0022] In this solution, the wheel limiting device lifts together with the lifting platform of the lift, which is not conducive to setting the drainage pipeline. Therefore, the dirt is discharged by dropping from the sewage discharge port at the bottom of the mounting seat into the receiving cavity on the base and then being discharged, which simplifies the structure setting and improves the sewage discharge effect at the same time.

[0023] Preferably, a discharge port is provided at the bottom of the receiving cavity, and the discharge port is connected to an external sewage discharge device.

[0024] In this solution, with the above structure setting, the dirt falling from the wheels of the battery swapping vehicle passes through the wheel limiting device and drops into the receiving cavity on the base through the sewage discharge port, and then is discharged to the outside of the lift through the discharge port and the sewage discharge device. Impurities such as dust and gravel in the dirt will be discharged together with rainwater and muddy water. If the dirt is not easily discharged, it can be discharged by flushing with water.

[0025] A battery swapping station, which includes the lift as described above. The battery swapping station is provided with a receiving cavity on the ground corresponding to the sewage discharge port. The base of the lift is a hollow structure, and the receiving cavity is arranged in the hollow area of the base.

[0026] In this solution, by setting the base of the lift as a hollow structure, the dirt falling from the wheels of the battery swapping vehicle is discharged to the receiving cavity on the ground through the sewage discharge port, without setting a receiving cavity on the base of the lift, so as to simplify the structure setting of the lift and reduce the manufacturing cost of the lift.

[0027] On the basis of conforming to the common knowledge in the field, the above preferred conditions can be combined arbitrarily to obtain various preferred examples of the present invention.

[0028] The positive and progressive effects of the present invention are as follows: When the battery-swapping vehicle drives into the wheel limiting device, some dirt (sand particles, dust, snow, and sewage) attached to the tire surface will be brought into the wheel limiting device. To ensure the normal use of the wheel limiting device, a sewage discharge port is provided at the bottom of the accommodating cavity of the mounting seat. Dirt brought by the tire into the wheel limiting device will fall from the tire into the lower accommodating cavity and then be discharged through the sewage discharge port of the accommodating cavity, preventing sewage, dust, and melted snow from accumulating at the bottom of the mounting seat and affecting the normal use of the wheel limiting device.

[0046] The present invention will be more clearly and completely described below by way of examples in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described examples.

[0047] As shown Figures 1 - 4 in the figure, this embodiment discloses a wheel limiting device. The wheel limiting device 10 is arranged on a lift in a battery swapping station and is used to limit the wheels of a battery swapping vehicle. The wheel limiting device 10 includes a mounting base 1 and a limiting mechanism 2. The mounting base 1 has a receiving cavity 11 with an open upper end. The limiting mechanism 2 is installed in the receiving cavity 11. The bottom of the receiving cavity 11 has a sewage discharge port 111 that penetrates up and down, so that dirt falling from the wheels of the battery swapping vehicle passes through the limiting mechanism 2 and is discharged to the outside of the wheel limiting device 10 through the sewage discharge port 111. When the battery swapping vehicle drives into the wheel limiting device 10, the vehicle will bring some dirt (sand grains, dust, snow or sewage) attached to the tire surface into the wheel limiting device 10. To ensure the normal use of the wheel limiting device 10, the sewage discharge port 111 is provided at the bottom of the receiving cavity 11 of the mounting base 1, so that the dirt brought by the tire into the wheel limiting device 10 falls from the tire into the lower receiving cavity 11 and then is discharged through the sewage discharge port 111 of the receiving cavity 11, preventing sewage, dust, and melted snow from accumulating at the bottom of the mounting base 1 and affecting the normal use of the wheel limiting device 10.

[0048] As shown Figure 1 in the figure, the limiting mechanism 2 includes a number of rollers. The number of rollers is divided into two rows and is installed on the mounting base 1 at intervals to form a downwardly concave V-shaped groove structure. When the battery swapping vehicle stops on the V-shaped groove structure, under the action of gravity, the wheels can roll from the edge of the V-shaped groove structure to the lowest point in the middle of the V-shaped groove structure and stop at the lowest point of the V-shaped groove structure, realizing automatic rough centering.

[0049] As shown Figures 1 - 3 in the figure, in this embodiment, the sewage discharge port 111 includes a first sewage discharge port 1111. A first sewage discharge port 1111 is provided below each row of rollers to improve the sewage discharge effect.

[0050] As shown Figure 1 in the figure, the projection of each row of rollers in the vertical direction is located inside the first sewage discharge port 1111, so that the dirt falling off the wheels can fall into the first sewage discharge port 1111 after passing through the gaps between the rollers, improving the sewage discharge effect.

[0051] As shown Figures 1 - 3As shown, the mounting base 1 has two side plates 12 for mounting the limiting mechanism 2 and a bottom plate 13 that fixes the two side plates 12 below the limiting mechanism 2. Two first sewage outlets 1111 are formed by hollowing out the bottom plate 13, and a reinforcing plate 14 is provided in the interval area corresponding to the two rows of rollers. The first sewage outlets 1111 are formed on both sides of the reinforcing plate 14. By providing the reinforcing plate 14, the strength of the mounting base 1 is ensured. The first sewage outlets 1111 are provided on both sides of the reinforcing plate 14 and correspond to the two rows of rollers one by one, improving the sewage discharge effect. At the same time, through the hollow design, two first sewage outlets 1111 and the reinforcing plate 14 are directly formed, facilitating the processing and manufacturing of the mounting base 1.

[0052] As Figure 2 and Figure 3 shown, the sewage outlet 111 further includes a second sewage outlet 1112 provided on the reinforcing plate 14. The second sewage outlet 1112 is provided to discharge the dirt that falls from the interval between the two rows of rollers, improving the sewage discharge effect. Preferably, the number of the second sewage outlets 1112 is multiple, and the multiple second sewage outlets 1112 are arranged at intervals along the length direction of the reinforcing plate 14, further improving the sewage discharge effect.

[0053] As Figure 4 shown, this embodiment also discloses a lift, which includes a base 20 and a lifting platform 30. Wheel limiting devices 10 as described above are respectively provided at both ends of the lifting platform 30. The lifting platform 30 is installed on the base 20 and can lift relative to the base 20. The two wheel limiting devices 10 on the lifting platform 30 are respectively used for limiting and fixing the left and right wheels at one end of the battery swapping vehicle.

[0054] A receiving cavity for receiving dirt (not shown in the figure) is provided on the base 20, and the sewage outlet 111 and the receiving cavity are correspondingly arranged. Since the wheel limiting device 10 lifts together with the lifting platform 30 of the lift, it is not conducive to setting up drainage pipes. Therefore, the dirt is discharged by dropping from the sewage outlet 111 at the bottom of the mounting base 1 into the receiving cavity on the base 20 and then being discharged, simplifying the structural setting and also improving the sewage discharge effect.

[0055] Preferably, a discharge port is provided at the bottom of the receiving cavity, and the discharge port is connected to an external sewage disposal device. The dirt that falls from the wheels of the battery swapping vehicle passes through the wheel limiting device 10 and drops into the receiving cavity of the base 20 through the sewage outlet 111, and then is discharged to the outside of the lift through the discharge port and the sewage disposal device. Impurities such as dust and gravel in the dirt will be discharged together with rainwater and muddy water. If the dirt is not easily discharged, it can be discharged by flushing with water.

[0056] This embodiment also discloses a battery swapping station, which includes the lift as described above. The battery swapping station is provided with a receiving cavity on the ground corresponding to the sewage outlet 111. The base 20 of the lift is of a hollow structure, and the receiving cavity is arranged within the hollow area of the base 20. By setting the base 20 of the lift to be of a hollow structure, the dirt falling from the wheels of the battery swapping vehicle can be discharged through the sewage outlet 111 to the receiving cavity on the ground, without the need to provide a receiving cavity on the base 20 of the lift, so as to simplify the structural arrangement of the lift and reduce the manufacturing cost of the lift.
