Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery swapping technology, and in particular to a battery swapping cabinet with a laser ranging device. Background Technology

[0002] In the daily operation of electric vehicle battery swapping stations, the efficiency of the battery swapping process is crucial to both user experience and the station's operational efficiency. Currently, the common battery swapping model adopted by battery swapping stations is as follows: after a vehicle enters the swapping station, a transfer trolley retrieves the battery from under the vehicle and transports it to the swapping cabinet.

[0003] However, existing technologies have some shortcomings in battery transport and swapping processes. During the swapping process, after the battery is picked up from the bottom of the vehicle by a transport trolley, it needs to be accurately placed into the swapping cabinet for replacement. Due to the uncertainty of the vehicle's parking posture, the battery may be at a certain angle when picked up. Existing technologies are not precise enough in identifying this battery angle, making it difficult to accurately determine the battery's posture during transport to the swapping cabinet. This increases the probability of swapping failure and reduces swapping efficiency.

[0004] Furthermore, existing battery swapping cabinets lack effective battery attitude recognition devices at the battery inlet and outlet, making it impossible to obtain battery deflection angle information in a timely manner. Consequently, they cannot provide accurate attitude data support for subsequent battery swapping operations. This not only affects the smoothness of the battery swapping process but also increases the operational complexity and failure risk of the battery swapping equipment.

[0005] In summary, existing battery swapping technologies have shortcomings in battery deflection angle identification and the accuracy of the swapping process. There is an urgent need for a technical solution that can effectively identify battery deflection angle to improve swapping efficiency and accuracy, reduce the failure rate, and provide more reliable technical support for the development of the electric vehicle battery swapping industry. Utility Model Content

[0006] The purpose of this invention is to provide a battery swapping cabinet with a laser ranging device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following solution:

[0008] A battery swapping cabinet with a laser ranging device includes a battery swapping cabinet, a data storage unit is provided inside the battery swapping cabinet, a channel frame is provided at the front end of the battery inlet and outlet of the battery swapping cabinet, and two sets of first ranging devices are horizontally spaced on one side wall of the channel frame along the direction of battery entry and exit from the battery swapping cabinet.

[0009] The two sets of the first ranging devices are respectively connected to the data storage unit.

[0010] Furthermore, two sets of second ranging devices are horizontally spaced on the other side wall of the channel frame along the direction of the battery entering and exiting the battery swapping cabinet, and the two sets of second ranging devices are respectively connected to the data storage unit.

[0011] Furthermore, a third ranging device is provided on the top wall of the channel frame facing the direction in which the battery enters and exits the battery swapping cabinet.

[0012] Furthermore, the first ranging device is a laser ranging device or an ultrasonic ranging device.

[0013] Furthermore, the first ranging device and the second ranging device are laser ranging devices or ultrasonic ranging devices.

[0014] Furthermore, the first ranging device, the second ranging device, and the third ranging device are laser ranging devices or ultrasonic ranging devices.

[0015] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By installing two horizontally spaced laser ranging devices on the side of the channel frame at the front end of the battery inlet and outlet of the battery swapping cabinet, two points in the horizontal direction of the battery (or battery compartment) can be accurately measured, thereby accurately recording its original tilt attitude (angle). This precise identification function provides reliable data support for subsequent battery swapping operations, avoiding the risk of battery swapping failure due to uncertain battery attitude.

[0017] 2. Because the deflection angle of the battery (or battery compartment) can be quickly identified at the front end of the battery swapping cabinet, there is no need to strictly correct the vehicle's parking posture at the battery swapping station, greatly saving the time spent on parking and aligning the vehicle. This not only shortens the driver's waiting time for battery swapping but also improves the overall operational efficiency of the battery swapping station, making the battery swapping process smoother and more efficient.

[0018] 3. In existing technologies, the high-power correction devices added to correct vehicle parking posture not only increase the complexity and failure rate of the equipment, but also increase the construction and maintenance costs of the battery swapping station. This invention reduces the need for vehicle parking posture correction by accurately identifying the deflection angle of the battery (or battery compartment), thereby reducing the equipment failure rate and the operating cost of the battery swapping station, and improving the reliability and service life of the equipment.

[0019] 4. No need to correct the vehicle's parking posture, avoiding the driver's anxiety caused by vehicle movement, providing electric vehicle users with a more convenient and comfortable battery swapping experience, and helping to improve user satisfaction and loyalty to the battery swapping station.

[0030] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0031] Example 1

[0032] See Figure 1-2 As shown, this embodiment provides a battery swapping cabinet with a laser ranging device, including a battery swapping cabinet 1. The battery swapping cabinet 1 is equipped with a data storage unit. The feature is that a channel frame 2 is provided at the front end of the battery 3 inlet and outlet of the battery swapping cabinet 1. Two sets of first ranging devices 4 are horizontally spaced on one side wall of the channel frame 2 along the direction of the battery 3 entering and exiting the battery swapping cabinet 1. The two sets of first ranging devices 4 are respectively connected to the data storage unit.

[0033] Specifically, the channel frame 2 refers to the support structure installed at the front end of the battery 3 inlet and outlet of the battery swapping cabinet 1. It can be made of materials such as a metal frame and is used to fix the ranging device and form the entry and exit path of the battery 3. The first ranging device 4 refers to the sensor used to detect the distance from the surface of the battery 3. It can be implemented by a laser ranging module or an ultrasonic sensor. They are arranged at intervals to cooperate in capturing the distance data between two symmetrical points on the same side wall of the battery 3 and the first ranging device 4 that detects the points. The data storage unit can be used to record the ranging data. It can be implemented by an embedded controller or an industrial computer. The angle of deflection of the battery 3 is inferred by receiving the two sets of ranging signals.

[0034] By measuring two points in the horizontal direction of battery 3 (or battery compartment) to record the original tilt posture (angle) of battery 3 (or battery compartment), and sending the posture (angle) data to the data storage unit of battery swapping cabinet 1, it is easy to correct battery 3 (or battery compartment) to the normal battery swapping posture in subsequent work. Then, the gripping device of battery swapping cabinet 1 will grab the feeding battery 3, and the process of sending battery 3 is reversed.

[0035] Specifically, when battery 3 enters channel frame 2, two sets of horizontally spaced first ranging devices 4 continuously detect the distance values ​​at different positions on the same sidewall of battery 3. When battery 3 exhibits horizontal deflection, the distance difference obtained by the two sets of ranging devices changes with the deflection angle. The data storage unit analyzes the difference between the two sets of distance data to calculate the real-time deflection angle of battery 3. This information can then be transmitted to other systems, such as a battery 3 adjustment system, to adjust the deflection angle of battery 3.

[0036] The installation positions of the two sets of first ranging devices 4 can be as follows: Figure 2 As shown.

[0037] Example 2

[0038] This embodiment provides a battery swapping cabinet with a laser ranging device. The difference between this embodiment and Embodiment 1 is that this embodiment also includes two sets of second ranging devices (not shown in the attached drawings, but can be referenced) horizontally spaced at intervals on the other side wall of the channel frame 2 along the direction in which the battery 3 enters and exits the battery swapping cabinet 1. Figure 2 The positions of the two sets of first ranging devices 4 correspond to the installation of two sets of second ranging devices, and the two sets of second ranging devices are respectively connected to the data storage unit.

[0039] The second ranging device refers to a sensor installed on the side wall of the channel frame 2 to measure the distance between the battery 3 and its surface. Specifically, it can be implemented using a laser ranging device or an ultrasonic ranging device, calculating distance data by emitting and receiving reflected signals. The horizontal spacing setting refers to the two sets of ranging devices being arranged in a non-overlapping manner on the same plane. This can be achieved by adjusting the spacing using fixed brackets or sliding rails, ensuring that distance information to the battery 3 surface is obtained from different positions.

[0040] Specifically, when battery 3 enters the passage frame 2 of battery swapping cabinet 1, two sets of second ranging devices synchronously scan the surface of battery 3 from the other side wall. By measuring the time difference or phase difference of reflected signals at different positions, corresponding distance data is generated and transmitted to the data storage unit. The data storage unit compares and analyzes the data from the two sets of second ranging devices, and combines it with the data from the first ranging device 4 to determine whether battery 3 has lateral deflection or tilt. For example, if the difference between the data measured by the two ranging devices exceeds a preset threshold, the battery 3 is determined to have an abnormal posture.

[0041] Specifically, the first ranging device 4 and the second ranging device are the same device, perform the same function, and cooperate with each other to make the inference of the deflection angle of the battery 3 more accurate.

[0042] Example 3

[0043] See Figure 1-3This embodiment provides a battery swapping cabinet with a laser ranging device. Based on embodiment two, this embodiment has a third ranging device 5 installed on the top wall of the channel frame 2 in the direction of the battery 3 entering and exiting the battery swapping cabinet 1.

[0044] The installation location of the third ranging device 5 can be found in [reference]. Figure 3 The location shown could also be another location.

[0045] The third ranging device 5 refers to a sensor used to measure the distance between the side wall of the battery 3 facing the battery swapping cabinet 1 and the ranging device. Specifically, it can be implemented using a laser ranging module or an ultrasonic ranging module, which calculates distance data by emitting signals and receiving reflected signals. The direction facing the battery 3 as it enters or exits the battery swapping cabinet 1 means that the signal transmission direction of the ranging device is aligned with the positive direction of the battery 3's movement path. This can be achieved by adjusting the sensor angle or setting a positioning reference to ensure that the measuring axis coincides with the plane of the battery 3's movement.

[0046] Specifically, the third ranging device 5 can be installed at the center of the top wall of the channel frame 2, and its signal coverage area overlaps with the vertical projection of the battery 3's entry and exit path. When the battery 3 enters or exits the battery swapping cabinet 1 in a horizontal direction, the third ranging device 5 continuously collects the distance data between the side wall of the battery 3 facing the battery swapping cabinet 1 and the sensor, and transmits the data to the data storage unit.

[0047] Specifically, when battery 3 enters the passage frame 2 of battery swapping cabinet 1, the ranging devices on both side walls (i.e., the first ranging device 4 and the second ranging device) detect the distance data of the left and right edges of battery 3 using laser or ultrasonic waves. The vertical ranging device at the top simultaneously detects the distance between battery 3 and battery swapping cabinet 1 (by calculation, the distance between the side wall of battery 3 facing battery swapping cabinet 1 and the ranging device can be calculated as the distance between the side wall of battery 3 facing battery swapping cabinet 1 and battery swapping cabinet 1). The real-time distance information collected by the three sets of ranging devices is transmitted to the data storage unit, and the attitude deflection angle of battery 3 in three-dimensional space is calculated through a coordinate transformation algorithm.

[0048] Specifically, the third ranging device is the same as the first ranging device 4 (or the second ranging device), performs the same function, and works together to make the inference of the deflection angle of the battery 3 more accurate.

[0049] 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.
