[0049] Heavy trucks can meet different types of freight transportation needs due to their strong load capacity and excellent driving performance, and are widely used in freight transportation field, playing a key role in promoting social and economic development. Correspondingly, heavy trucks also have the problem of huge energy consumption. Under the background of rapid development of new energy vehicles, electric heavy trucks emerge as the times require. Compared with traditional heavy trucks, new energy heavy trucks are more energy-saving and environmentally friendly, and have lower operation and maintenance costs.

[0050] To solve the problem of high energy consumption of new energy heavy trucks and improve their endurance, it is usually necessary to equip them with large-capacity batteries. Once the large-capacity batteries run out of power, it takes a long time to charge, and the new energy heavy trucks have to be out of service for a long time, which is extremely unfavorable for the normal development of production activities. Therefore, for new energy heavy trucks, modular overall battery replacement is a better solution to the endurance problem: before the battery runs out of power, go to the battery replacement station, take out the battery that is about to run out of power, and replace it with a fully charged battery. The new energy heavy truck can continue to run, and such a solution can improve production efficiency.

[0051] In the battery replacement process, whether the battery is locked in place or not is related to the reliability of electrical connection, which is very important for driving safety. However, the battery is usually located at the bottom of the vehicle, so how to conveniently, quickly and accurately detect the battery locking condition is a technical problem that needs to be solved in the industry.

[0052] For example,Figure 1 And Figure 2 As shown in the figure, in order to solve the above problems, the utility model provides a heavy truck battery lock detection device, including support casing 1, image acquisition module 2, refraction component 3 and infrared filter 4. Among them, support casing 1 is as the structural component, its effect is to play the structural support effect to image acquisition module 2, refraction component 3 and infrared filter 4 etc.;Image acquisition module 2, refraction component 3 and infrared filter 4 are as functional components, the effect of image acquisition module 2 is to carry out real-time image acquisition, this technical scheme adopts camera module as image acquisition module 2, the effect of refraction component 3 is to change the light path structure, and the effect of infrared filter 4 is to filter other light rays except infrared light.

[0053] The support casing 1 is a square cylindrical structure, the support casing 1 includes a first support plate, a second support plate, a third support plate and a fourth support plate, the first support plate, the second support plate, the third support plate and the fourth support plate are sequentially connected by side edges to form the support casing 1, and a filter window 101 is formed in the first support plate.

[0054] The image acquisition module 2 and the refraction component 3 are respectively fixedly arranged at two ends in the support casing 1, the image acquisition module 2 faces the refraction component 3, and the infrared filter 4 is fixedly arranged on the filter window 101, external light is refracted by the refraction component 3 after passing through the infrared filter 4 and enters the image acquisition module 2.

[0055] On the heavy truck, the battery is fixedly arranged at the bottom of the truck, the battery is electrically connected with the outside through an electrical connecting piece, and the lock condition between the battery and the electrical connecting piece represents the reliability of the electrical connection: when the lock is in place, it indicates that the battery connection of the heavy truck is reliable;When the lock is not in place, it indicates that the battery connection of the heavy truck is unreliable. The so-called lock condition represents the battery connection condition.

[0056] The space of the heavy truck bottom is originally narrow, and the space of the bottom is further compressed after assembling the battery, and under this premise, the lock detection device is further arranged, and since the lock detection device occupies a large volume in the vertical direction, it will have a great impact on the heavy truck.

[0057] In order to solve this problem, the image acquisition module 2 and the refraction component 3 are fixedly arranged in the support casing 1, so that the structure is formed into a flat structure, the volume of the device in the vertical direction is compressed, and through reasonable and scientific structural design, the battery at the bottom of the heavy truck can be conveniently, quickly and accurately detected.

[0058] When installing, the filter window 101 is aligned with the drop lock connection of the battery, the light of the drop lock connection is transmitted to the refracting assembly 3 after passing through the infrared filter 4, is refracted into the image acquisition module 2 after being refracted by the refracting assembly 3, the corresponding image data is acquired by the image acquisition module 2, and the drop lock condition of the battery can be acquired in real time by further analyzing and processing the image data. In the technical solution, the data processing process is not creatively improved, but the structure of the battery drop lock detection device is optimized for the problem of insufficient space of the heavy truck bottom, and the vertical space of the device is compressed to meet the actual application requirements.

[0059] As shown in Figure 3 Preferably, the refracting assembly 3 comprises a refracting plane mirror 301 and a plane mirror support frame, wherein the refracting plane mirror 301 is used for changing the light path, and the plane mirror support frame is used for supporting and fixing the refracting plane mirror 301. Specifically, the plane mirror support frame comprises a plane mirror support top plate 302, a plane mirror support bottom plate 303 and a plane mirror support side plate 304, the plane mirror support top plate 302 and the plane mirror support bottom plate 303 are connected and fixed through the plane mirror support side plate 304, a plane mirror fixing inclined table 305 is arranged between the plane mirror support top plate 302 and the plane mirror support bottom plate 303, and the refracting plane mirror 301 is fixedly arranged on the plane mirror fixing inclined table 305; the plane mirror support frame is fixedly arranged in the inside of the support shell 1 through the plane mirror support bottom plate 303, a heat dissipation gap is formed between the plane mirror support top plate 302 and the plane mirror support bottom plate 303, and the infrared filter 4 is located above the plane mirror support top plate 302.

[0060] In the technical solution, the light path is changed mainly through the refracting plane mirror 301, which needs to form a certain angle between the image acquisition module 2 and the refracting plane mirror 301, and the relative angle needs to be kept unchanged for a long time. Therefore, how to fix the refracting plane mirror 301 is one of the important technical problems to be solved in the technical solution.

[0061] In the technical solution, the plane mirror support frame is formed through the plane mirror support top plate 302, the plane mirror support bottom plate 303, the plane mirror support side plate 304 and the plane mirror fixing inclined table 305, and the refracting plane mirror 301 is fixedly arranged on the plane mirror support frame. The light path is changed by using the refracting plane mirror 301, so that the technical purpose of compressing the volume of the device in the vertical direction is achieved. In addition, the heat dissipation gap is formed between the plane mirror support top plate 302 and the plane mirror support bottom plate 303, which can effectively improve the heat dissipation efficiency of the device.

[0062] As shown in Figure 3As shown, preferably, the plane mirror support top plate 302 has a light-transmitting hole, and a light-blocking sleeve 5 is provided outside the light-transmitting hole. An LED light group 6 is fixedly installed on the plane mirror support top plate 302, and the LED light group 6 is located on the side of the light-blocking sleeve 5. The lower surface of the infrared filter 4 abuts and is fixed to the upper edge of the light-blocking sleeve 5.

[0063] The lighting conditions under heavy trucks are generally very poor and unstable. To solve this problem, this technical solution has an LED light group 6 fixedly installed on the top plate 302 of the plane mirror support. During operation, the LED light group 6 emits light to provide a detection light source, ensuring good "visibility conditions" for the image acquisition module 2.

[0064] However, once the light emitted by the LED light group 6 enters the image acquisition module 2, it will negatively affect the image acquisition module 2, causing it to be unable to properly acquire real-time images of the locking situation, or causing the real-time images to be distorted, thus affecting the judgment. To solve this problem, a light-blocking sleeve 5 is set outside the light-transmitting hole, and the LED light group 6 is located on the side of the light-blocking sleeve 5. On this basis, the lower surface of the infrared filter 4 is fixed to the upper edge of the light-blocking sleeve 5. In this way, the light emitted by the LED light group 6 can only pass through the infrared filter 4 to the battery locking connection, and cannot pass through the light-blocking sleeve 5 to enter the image acquisition module 2.

[0065] Based on the above structure, the detection light source is provided by the LED light group 6, and the image acquisition is performed by the detection light source, which can minimize the impact of the ambient light source on the image data. Furthermore, by placing the LED light group 6 on the side of the light blocking sleeve 5, the light emitted by the LED light group 6 can be prevented from directly entering the image acquisition module 2, thereby reducing the impact of the detection light source on the image data.

[0066] like Figure 4 As shown, preferably, the LED light group 6 is disposed on a light group circuit board 7, the light group circuit board 7 has a socket hole 701 in the middle, and the light group circuit board 7 is sleeved on the light blocking sleeve 5 through the socket hole 701; the light group circuit board 7 is fixedly disposed on the plane mirror support top plate 302 by a circuit board connecting bolt 702, and a support copper tube 703 is sleeved on the circuit board connecting bolt 702.
