Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery swapping technology, and in particular to a battery swapping system with vehicle distance measurement and control of the movement distance of the transfer trolley. Background Technology

[0002] In the field of new energy vehicles, battery swapping, as an efficient energy replenishment method, is being used more and more widely. Existing battery swapping stations typically use cameras and displays to show the vehicle's location, guiding drivers to park their vehicles in the swapping bays. Limiting devices are also installed at the bottom of the swapping bays, primarily to restrict the position of the vehicle's tires, ensuring the vehicle is accurately parked in the bay, thus facilitating subsequent battery swapping operations.

[0003] However, this existing battery swapping guidance method has some obvious drawbacks. Firstly, the vehicle position image displayed on the screen cannot provide drivers with a comprehensive and accurate understanding of whether their vehicle is parked in the correct swapping bay, especially when there is a slight deviation between the vehicle and the bay, making it difficult for drivers to make an accurate judgment based solely on the screen image. Secondly, image recognition technology itself has latency issues, which may cause drivers to miss the optimal parking position when adjusting the vehicle's position based on the screen image. Furthermore, the limiting devices at the bottom of the swapping bay are prone to mechanical failure under frequent impacts from vehicle tires, which not only affects the smooth operation of the swapping process but may also increase the maintenance costs and repair frequency of the swapping station, causing considerable inconvenience to its normal operation. Utility Model Content

[0004] The purpose of this invention is to provide a battery swapping system that can measure vehicle distance and control the movement distance of the transfer trolley, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A battery swapping system with vehicle ranging and control of the movement distance of a transfer trolley includes a battery swapping cabinet and a transfer trolley that cooperate with each other. The battery swapping cabinet is equipped with a data processing unit and an ultrasonic ranging device for identifying the parking position of the vehicle is installed on the battery swapping cabinet. The ultrasonic ranging device is connected to the data processing unit.

[0007] The transfer trolley is equipped with a PLC controller and a laser ranging device for identifying the distance between the transfer trolley and the battery swapping cabinet. The PLC controller is connected to the data processing unit and the laser ranging device respectively.

[0008] Furthermore, it also includes a parking platform corresponding to the battery swapping cabinet, the parking platform comprising two sets of correspondingly arranged single-sided bridge structures with a gap between the two sets of single-sided bridge structures.

[0009] Furthermore, the top of the transfer trolley is provided with a support platform, and the transfer trolley is provided with a lifting component that can raise and lower the support platform.

[0010] Furthermore, the transfer trolley is equipped with a rotating component that can rotate the carrying platform.

[0011] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The ultrasonic ranging device can accurately identify the parking distance of the vehicle and feed the distance information back to the data processing unit. The transfer trolley automatically drives to the corresponding position under the vehicle based on this information, without the need for the driver to accurately adjust the front and rear distance of the vehicle. This effectively solves a series of problems caused by the driver's inaccurate parking in the existing technology.

[0013] During its movement, the transfer trolley uses a laser rangefinder to identify the distance to the battery swapping cabinet in real time, ensuring that it stops precisely below the vehicle's parking position. This greatly improves the success rate of the battery swapping trolley in grabbing batteries, reduces the time required for readjustment due to inaccurate positioning, and thus significantly saves the driver's battery swapping time and improves the overall operating efficiency of the battery swapping system.

[0014] In existing technologies, the limiting devices at the bottom of the battery swapping station are prone to mechanical failure due to repeated impacts from vehicle tires, increasing maintenance costs and repair frequency. This invention, through the coordinated operation of an ultrasonic ranging device and a transfer trolley, eliminates the need for vehicles to frequently rely on the limiting devices for parking and positioning. This reduces the number of impacts on the limiting devices, lowers the probability of mechanical failure, improves the stability and reliability of the battery swapping station equipment, and reduces equipment maintenance costs and workload.

[0024] Example

[0025] See Figure 1 As shown, this embodiment provides a battery swapping system with vehicle ranging and control of the movement distance of the transfer trolley, including a battery swapping cabinet 1 and a transfer trolley 2 that cooperate with each other. The battery swapping cabinet 1 is equipped with a data processing unit, and the battery swapping cabinet 1 is equipped with an ultrasonic ranging device for identifying the parking position of the vehicle. The ultrasonic ranging device is connected to the data processing unit.

[0026] The transfer trolley 2 is equipped with a PLC controller and a laser ranging device for identifying the distance between the transfer trolley 2 and the battery swapping cabinet 1. The PLC controller is connected to the data processing unit and the laser ranging device respectively.

[0027] Specifically, the ultrasonic ranging device feeds back the identified vehicle parking position information (distance information) to the data processing unit. The data processing unit then sends the vehicle parking position information to the transfer trolley 2. The transfer trolley 2 sets its moving distance based on this information. During the movement, the laser ranging device identifies the distance to the battery swapping cabinet 1, and the trolley eventually moves to the position corresponding to the vehicle parking position information. The PLC controller obtains the vehicle parking position data measured by the ultrasonic ranging device from the data processing unit and directly controls the moving distance of the transfer trolley. Therefore, the vehicle can be parked near the parking space without needing to adjust the front and rear distances. The battery swapping trolley automatically moves to the bottom of the vehicle based on the parking position, saving the driver's battery swapping time and improving the success rate of the battery swapping trolley grabbing the battery compartment.

[0028] It should be noted that the appendix Figure 1 The PLC controller / ultrasonic ranging device, data processing unit, and laser ranging device are not shown in the diagram. These devices or units can be installed according to the actual situation.

[0029] Specifically, an ultrasonic ranging device is installed directly in front of the battery swapping cabinet 1, and a laser ranging device is installed in the direction of the transfer trolley 2 facing the battery swapping cabinet 1.

[0030] It should be noted that the battery swapping system also includes a parking platform 3 corresponding to the battery swapping cabinet 1. The parking platform 3 includes two sets of corresponding single-sided bridge structures with a gap between them, so that after the vehicle drives to the parking platform 3 and stops, the transfer trolley 2 can drive through the gap between the two sets of single-sided bridge structures to directly under the vehicle to pick up the battery.

[0031] Specifically, the top of the transfer trolley 2 is equipped with a support platform for carrying the battery compartment. The transfer trolley 2 is equipped with a lifting component for lifting the support platform and a rotating component for rotating the support platform, which makes it easy to pick up and adjust the battery.

[0032] It should be noted that the platform can support both the battery and the battery compartment.

[0033] It should be noted that the appendix Figure 1 The lifting and rotating components are not shown in the diagram; these components can be installed according to the actual situation.

[0034] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
