Description

Technical Field

[0001] The present invention relates to the field of battery swap stations, and in particular to a vehicle positioning device and a battery swap station. Background Art

[0002] The problems of low battery energy storage and unsatisfactory mileage after a single charge have always restricted the development of electric vehicles. At present, the power supply methods of electric vehicle power batteries are generally divided into two methods: plug-in charging with the car and replacing the battery. The plug-in charging method has two modes: slow charging and fast charging. The plug-in charging method has the following defects: 1. The initial investment cost of the battery is large, which to a certain extent hinders the popularization of electric vehicles; 2. The charging time is too long, at least 2 to 4 hours. Compared with the refueling of ordinary cars, the time spent on electric vehicles to replenish energy is too long, which is very inconvenient and far from meeting people's needs. The fast charging mode will cause great damage to the battery, resulting in a shortened battery life. The use of battery replacement can effectively avoid the problems of the plug-in charging method. The battery replacement solution has become a more popular method of electric vehicle power replenishment because it can complete the power supply of electric vehicles in a very short time and will not affect the service life of the power battery.

[0003] Battery replacement is usually carried out in a battery swap station. A battery swap station generally includes a battery swap platform for replacing electric vehicle batteries, a battery compartment for storing and replenishing power for depleted batteries, and a battery swap cart for carrying fully charged / depleted power batteries between the battery swap platform and the battery compartment. In the prior art, when replacing batteries, it is first necessary to drive the electric vehicle to the target position on the battery swap platform so that the battery swap cart is located below the battery pack of the vehicle chassis, and then use the lifting mechanism to lift the battery swap cart so that the battery swap cart is suitable for vehicles with different chassis heights. However, if the vehicle does not enter the target area on the battery swap platform, the battery swap cart cannot accurately replace the battery pack. In addition, the positioning method of driving the vehicle to the target area has a large subjective factor and requires extremely high driving experience from the driver. If the entry position is inaccurate, the driver needs to adjust the vehicle position multiple times until the accurate battery swap position is reached. The positioning time is long, which not only causes a poor user experience but also seriously affects the vehicle's battery swap efficiency.

[0004] In response to the above-mentioned problems existing in the prior art, the present application aims to provide a vehicle positioning device and a battery swap station, which can not only quickly and accurately locate an incoming vehicle and adjust the position of the vehicle so that the vehicle is in an appropriate battery swap position; but also save battery swap time, improve the accuracy and efficiency of battery swap, and enhance the user experience.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0031] Example

[0032] In order to improve the efficiency of battery pack replacement, battery swap stations often position the battery pack installed on the vehicle chassis by positioning the wheels. The positioning of the vehicle wheels is mostly determined by two slopes with a V-shaped cross-section. Specifically, when the vehicle drives to the middle of the slope, the wheels are stuck to achieve positioning along its own length. However, this structure cannot achieve positioning in the width direction of the vehicle body. When the vehicle enters the battery swap station and its centerline position is not aligned, it is still impossible to quickly replace the battery pack. To solve this problem, the prior art usually uses a mechanical arm to push the vehicle along the width direction of its body and push the vehicle horizontally to the target position. However, the mechanical arm has the following defects: First, the mechanical arm can only achieve movement in a single direction, which is not suitable for situations where the vehicle is in an inclined position; second, pushing the vehicle requires a sufficiently large driving force, which makes the mechanical arm consume a lot of energy and have a complex mechanical structure; third, the mechanical arm has the risk of causing damage to the wheels (or other parts).

[0033] In order to overcome the above-mentioned defects of the prior art, this embodiment provides a vehicle positioning device 100, please combine Figures 1 to 3 , the vehicle positioning device 100 includes a base 30, a first positioning mechanism 10, a second positioning mechanism 20 and a driving device 40;

The first receiving surface 31 and the second receiving surface 32 form an angle.

[0035] The first positioning mechanism 10 is installed on the first receiving surface 31, and the first positioning mechanism 10 includes a first conveyor belt 11 and a first roller assembly, the first roller assembly includes at least two rollers 50 distributed along the length direction of the first receiving surface 31, and the first conveyor belt 11 is wound on the first roller assembly;

[0036] The second positioning mechanism 20 is installed on the second receiving surface 32, and the second positioning mechanism 20 includes a second conveyor belt 21 and a second roller assembly, and the second roller assembly includes at least two rollers 50 arranged side by side along the length direction of the second receiving surface 32, and the second conveyor belt 32 is wound on the second roller assembly;

The first roller assembly can drive the first conveyor belt 11 to rotate under the driving action of the driving device 40; the second roller assembly can drive the second conveyor belt 21 to rotate under the driving action of the driving device 40.

[0038] Preferably, the angle formed by the first receiving surface 31 and the second receiving surface 32 is an obtuse angle.

The second fixing mechanism, the third fixing mechanism and the fourth fixing mechanism are similar to the first fixing mechanism.

[0050] In the embodiment of the present specification, a gap is formed between the first conveyor belt 11 and the first receiving surface 31. Since the two ends of the first positioning mechanism 10 are respectively connected to the first side beam 33 and the middle cross beam through the roller connecting portion 52, and the first conveyor belt 11 is wound on the first roller assembly, there is no contact between the first positioning mechanism 10 and the first receiving surface 31, so that the transmission of the first conveyor belt will not be affected by the resistance from the first receiving surface 31;

[0055] In some embodiments, the transmission direction of the first conveyor belt 11 is consistent with the transmission direction of the second conveyor belt 21 ; of course, the transmission direction of the first conveyor belt 11 may also be opposite to the transmission direction of the second conveyor belt 21 .

[0056] The first roller assembly includes a first active roller and a first driven roller, one end of the first conveyor belt 11 is wound around the first active roller, the other end of the first conveyor belt 11 is wound around the first driven roller, and the output shaft of the driving device 40 is connected to the first active roller;

[0057] Similarly, the second roller assembly includes a second active roller and a second driven roller, one end of the second conveyor belt 21 is wound on the second active roller, the other end of the second conveyor belt 21 is wound on the second driven roller, and the output shaft of the driving device 40 is also connected to the second active roller.
