Description

Technical Field

[0001] This invention relates to the technical field of battery replacement testing for logistics vehicles, and more specifically, to a verification system and method for replacing power batteries in logistics vehicles. Background Technology

[0002] An electric vehicle battery swapping station is a facility that provides power to electric vehicles through battery swapping. The station mainly comprises a power supply and distribution system, a charging system, a battery swapping system, a battery testing and maintenance system, and a monitoring system. Among these, the battery swapping system is the core system, and its efficiency determines the overall operational efficiency of the station. Unlike the overall layout of passenger car swapping stations, logistics vehicle swapping stations use V-grooves on the front wheels for X-axis positioning to determine the location of the battery and swapping brackets. Pure electric logistics vehicles use leaf spring suspensions at the front. Under different loads, the leaf springs deform differently, causing the wheel center to shift in the X-axis, meaning the distance from the front wheel center to the battery pack changes with the load. Currently, battery swapping for pure electric logistics vehicles is mainly semi-automatic, requiring manual verification and evaluation of the vehicle model to determine its compatibility with the swapping station. This verification and evaluation process is time-consuming and inefficient. Therefore, finding a quick and convenient way to verify and evaluate the compatibility of logistics vehicles with the swapping station is of great importance. Summary of the Invention

[0003] This invention provides a verification system and method for replacing power batteries in logistics vehicles, which solves the problem of low efficiency caused by the need for manual operation in the existing pure electric logistics vehicle power battery replacement for vehicle model matching. It can improve the convenience of vehicle model matching verification and improve the working efficiency of battery swapping stations.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A verification system for replacing power batteries in logistics vehicles includes: a host computer, a line scan camera, and a testing platform;

[0006] The detection platform is provided with a front wheel centering roller area and a rear wheel centering roller area. A power battery replacement slot is provided between the front wheel centering roller area and the rear wheel centering roller area. The power battery replacement slot is provided with an opening and closing door.

[0007] The testing platform is equipped with personnel access steps on both sides, and the line scan camera is movably set on the side of the power battery replacement slot to collect images and confirm the location of the battery pack identification features of the vehicle under test.

[0008] The host computer is connected to the line scan camera. The host computer identifies the corresponding model and size of the battery pack based on the battery pack identification feature image acquired by the line scan camera, and verifies whether the battery pack of the vehicle under test is compatible with the battery swapping station based on the identified battery pack model and size.

[0009] Preferably, it also includes: a laser rangefinder;

[0010] The laser rangefinder is movably mounted in the rear wheel centering roller area to detect the X-direction position of the battery pack;

[0011] The host computer is connected to the laser rangefinder and determines the battery pack replacement location based on the X-direction position of the battery pack.

[0012] Preferably, the testing platform is equipped with a lifting device that can move up and down when the vehicle battery is replaced.

[0013] Preferably, the testing platform is equipped with a side guardrail, the bottom of which is more than 65mm higher than the bottom of the battery pack of the vehicle under test.

[0014] Preferably, the front wheel centering roller area is provided with a V-shaped groove for centering and positioning the front wheels of the vehicle under test.

[0015] Preferably, it also includes: an encryption / unlocking platform;

[0018] Preferably, the host computer is equipped with a human-machine interface, through which operators can control and view information about the encryption / unlocking platform, the line scan camera, and the laser rangefinder.

[0019] This invention also provides a verification method for replacing the power battery of a logistics vehicle, using the above-mentioned verification system, comprising:

[0020] After the vehicle under test is positioned on the testing platform, the line scan camera is controlled to acquire images of the battery pack and confirm its position.

[0021] The corresponding model and size of the battery pack are identified based on the collected battery pack identification feature images;

[0022] The battery pack model and size of the vehicle under test are used to verify whether the battery pack is compatible with the battery swapping station.

[0023] Preferred options also include:

[0024] For vehicles with leaf spring front suspension, the battery pack location is identified by a line scan camera, and the height difference between the side guardrail and the battery pack is checked to ensure that the connection between the line scan camera and the identification feature is not obstructed by the side guardrail.

[0025] This invention provides a verification system and method for replacing power batteries in logistics vehicles. A line scan camera is movably mounted on the side of the testing platform to acquire images of the battery pack identification features of the vehicle under test. The host computer identifies the corresponding model and size of the battery pack based on the battery pack identification feature images acquired by the line scan camera, and verifies whether the battery pack of the vehicle under test is compatible with the battery swapping station based on the identified battery pack model and size.

It can improve the convenience of vehicle model matching verification and improve the working efficiency of the battery swapping station. Attached Figure Description

[0026] To more clearly illustrate the specific embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly described below.

[0027] Figure 1 This is a schematic diagram of a verification system for replacing the power battery of a logistics vehicle, provided by the present invention.

[0028] Figure 2 This is a schematic diagram of a verification method for replacing the power battery of a logistics vehicle provided by the present invention. Detailed Implementation

[0029] To enable those skilled in the art to better understand the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0030] To address the issue of low efficiency in the current practice of manually matching vehicle models when replacing power batteries for pure electric logistics vehicles, this invention provides a verification system and method for replacing power batteries in logistics vehicles. This system and method solves the problem of low efficiency caused by the manual matching of vehicle models when replacing power batteries for pure electric logistics vehicles, improves the convenience of vehicle model matching verification, and increases the working efficiency of battery swapping stations.

[0031] like Figure 1As shown, a verification system for replacing power batteries in logistics vehicles includes: a host computer, a line scan camera 1, and a testing platform. The testing platform has a front wheel centering roller area 21 and a rear wheel centering roller area 22. A power battery replacement slot 23 is provided between the front wheel centering roller area 21 and the rear wheel centering roller area 22, and the power battery replacement slot 23 has an opening and closing door 25. Personnel access platforms 24 are provided on both sides of the testing platform. The line scan camera 1 is movably mounted on the side of the power battery replacement slot 23 to acquire images and confirm the location of the battery pack identification features of the vehicle under test. The host computer is signal-connected to the line scan camera. The host computer identifies the corresponding model and size of the battery pack based on the battery pack identification feature images acquired by the line scan camera, and verifies whether the battery pack of the vehicle under test is compatible with the battery swapping station based on the identified battery pack model and size.

[0032] In practical applications, the front wheels of the battery swapping logistics vehicle must fall into the front wheel centering roller area. This roller has a certain range of movement to align the vehicle's battery with the unlocking platform. Simultaneously, the rear wheels must fall into the rear wheel centering roller area, ensuring that all tire treads touching the ground are within this area; otherwise, centering cannot be achieved. A line-scanning camera scans an area within a suitable range before and after the identification features on the battery pack frame to determine the battery's position and size, and acquires images of the battery pack's identification features, which can be RFID tags. The host computer obtains the corresponding battery pack model based on the identification feature images and determines whether it matches the battery swapping station based on the battery pack's position, size, and model. This system improves the convenience of vehicle matching verification, increases the efficiency of the battery swapping station, and reduces manual operation.

[0033] The system also includes: a laser rangefinder 3; the laser rangefinder 3 is movably disposed in the rear wheel centering roller area 22 to detect the X-direction position of the battery pack; the host computer is signal-connected to the laser rangefinder and determines the battery pack replacement position based on the X-direction position of the battery pack.

[0034] In practical applications, a laser rangefinder is installed in the center channel of the rear wheel centering area. During the battery swapping process, the laser rangefinder will rise and fall to remeasure the X-axis position of the battery pack. Therefore, the laser rangefinder motion envelope must not interfere with the vehicle end structure.

[0035] Furthermore, the testing platform is equipped with a lifting device that can move up and down when the vehicle's battery is being replaced.

[0036] Furthermore, the testing platform is equipped with a side guardrail, the bottom of which is more than 65mm higher than the bottom of the battery pack of the vehicle under test.

[0037] Meanwhile, the guide pin hole of the battery pack fixing frame requires that when the straight section of the battery pack positioning pin just contacts its internal straightness, there is still a Z-direction gap between the lock body T-head and the frame hole.

[0038] Furthermore, the front wheel centering roller area is provided with a V-shaped groove for centering and positioning the front wheels of the vehicle under test.

[0039] The system also includes: an unlocking platform 4; the unlocking platform 4 is connected to the host computer via signal and is located below the power battery replacement slot for docking and separating the battery pack from the vehicle chassis.

[0040] Furthermore, the host computer is equipped with an image processing and recognition algorithm to identify the RFID tag that identifies vehicle battery information from the battery pack identification feature image and decode the corresponding battery pack model.

[0041] Furthermore, the host computer is equipped with a human-machine interface, through which operators can control and view information about the encryption / unlocking platform, the line scan camera, and the laser rangefinder.

[0042] As can be seen, the present invention provides a verification system for replacing power batteries in logistics vehicles. A line scan camera is movably mounted on the side of the testing platform to acquire images of the battery pack identification features of the vehicle under test. The host computer identifies the corresponding model and size of the battery pack based on the battery pack identification feature images acquired by the line scan camera, and verifies whether the battery pack of the vehicle under test is compatible with the battery swapping station based on the identified battery pack model and size. This solves the problem that the existing pure electric logistics vehicle power battery replacement requires manual operation for vehicle model matching, which is inefficient. It can improve the convenience of vehicle model matching verification and improve the working efficiency of the battery swapping station.

[0043] Accordingly, such as Figure 2 As shown, the present invention also provides a verification method for replacing the power battery of a logistics vehicle, using the above-mentioned verification system, including:

[0044] S1: After the vehicle under test is in the set position on the detection platform, control the line scan camera to acquire images and confirm the position of the battery pack.

[0045] S2: Identify the corresponding model and size of the battery pack based on the collected battery pack identification feature image.

[0046] S3: Verify whether the battery pack of the vehicle under test is compatible with the battery swapping station based on the identified battery pack model and size.

[0047] The method also includes: for vehicles with leaf spring front suspension, identifying the battery pack position using a line scan camera and verifying the height difference between the side guardrail and the battery pack to ensure that the connection between the line scan camera and the identification feature is not obstructed by the side guardrail.

[0048] As can be seen, this invention provides a verification method for replacing the power battery of a logistics vehicle. It uses a line scan camera to acquire images of the battery pack, and identifies the corresponding model and size of the battery pack based on the acquired battery pack identification feature images. The method then verifies whether the battery pack of the vehicle under test is compatible with the battery swapping station based on the identified battery pack model and size. This solves the problem of low efficiency caused by the manual operation required for vehicle model matching in existing pure electric logistics vehicle power battery replacement systems, and improves the convenience of vehicle model matching verification, thereby increasing the working efficiency of the battery swapping station.

[0049] The structure, features, and effects of the present invention have been described in detail above with reference to the embodiments shown in the figures. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, shall be within the protection scope of the present invention as long as they do not exceed the spirit covered by the specification and figures.
