[0044] Battery Pack 200 DETAILED DESCRIPTION

[0045] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0046] like Figure 2 , Figure 3 and Figure 4 As shown, this embodiment discloses a battery swapping device, which includes a battery swapping platform 20 and at least one visual detection device 10. The battery swapping platform 20 is used to replace the battery pack 200 of the electric vehicle 100. Each visual detection device 10 is arranged at a predetermined position of the battery swapping platform 20 to detect the locked or unlocked state of the battery pack 200. The bottom of the electric vehicle 100 has a quick-change bracket 101, and the battery pack 200 is installed on the quick-change bracket 101. The battery swapping platform 20 can install the battery pack 200 on the quick-change bracket 101 or remove the battery pack 200 on the quick-change bracket 101 for replacement, so that the battery swapping device can replace the battery pack 200 on the electric vehicle 100 through the battery swapping platform 20. The battery swapping device detects whether the battery pack 200 and the quick-change bracket 101 are locked or unlocked through the visual detection device 10 to detect whether they are installed in place or unlocked successfully and replaced.

[0047] like Figure 4 As shown, the visual inspection device 10 includes a visual inspection body 1 and a reflector 2. The direction of the incident light path of the visual inspection body 1 is set to be non-perpendicular to the plane direction of the battery pack 200. The reflector 2 is set to be set on the incident light path of the visual inspection body 1 at a preset tilt angle, and is used to reflect the locked or unlocked state image of the battery pack 200 into the visual inspection body 1. The incident light is reflected onto the visual inspection body 1 by the reflector 2, so that the direction of the incident light path of the visual inspection body 1 is non-perpendicular to the plane direction of the battery pack 200. The visual inspection body 1 will not need to be directly facing the target to be inspected, thereby realizing the adjustment of the installation position of the visual inspection device 10 on the battery swap platform 20. The installation and setting are very convenient, and the installation space resources are saved. At the same time, the height of the battery swap equipment is reduced, which is greatly beneficial to the use of the battery swap equipment.

[0048] Among them, the angle between the mirror surface of the reflector 2 and the plane direction of the battery pack 200 is 30° to 60°. The mirror surface of the reflector 2 is tilted relative to the plane of the battery pack 200, and the locked or unlocked state image of the battery pack 200 is reflected into the visual detection body 1 through the mirror surface of the reflector 2. Preferably, the direction of the incident light path of the visual detection body 1 is parallel to the plane direction of the battery pack 200, and the reflector 2 is set at a 45° tilt angle. By setting the reflector 2 at a 45° tilt angle, that is, the angle between the mirror surface of the reflector 2 and the plane direction of the battery pack 200 is 45°, the incident light will be reflected by the reflector 2 onto the visual detection body 1, so that the direction of the incident light path of the visual detection body 1 is parallel to the plane direction of the battery pack 200, and the length direction of the visual detection body 1 is parallel to the plane direction of the battery swap platform 20 and is installed on the top surface of the battery swap platform 20. The installation is very convenient and occupies the least space resources.

[0049] The battery exchange equipment also includes two unlocking devices for unlocking and disengaging the battery pack 200 from the quick-change bracket 101 of the electric vehicle 100. The unlocking devices are arranged on the battery exchange platform 20. There are two visual inspection devices 10, which are arranged one by one at the corresponding positions of the unlocking devices. The multiple lock bases on the quick-change bracket 101 respectively lock the multiple lock shafts of the battery pack 200 through the lock tongues. When the battery exchange equipment unlocks the battery pack 200 on the electric vehicle 100, the two sides of the battery pack 200 can lift the lock tongue through the two unlocking devices, so that the lock shaft is free from the restraint of the lock tongue. After that, the battery exchange platform 20 will drive the movement of the battery pack 200 to make the lock shaft separate from the lock base.

[0050] The visual inspection device 10 is stationary on the battery exchange platform 20, and the visual inspection device 10 can photograph the lock base that is unlocked by the unlocking device, that is, the lock tongue is the target to be detected, and the visual inspection device 10 is used to photograph the lock tongue to detect the locked or unlocked state of the battery pack 200. The setting position of the visual inspection device 10 only needs to be able to photograph the target area. Of course, the visual inspection device 10 can also photograph the lock link, which is the target to be detected. The lock tongues of multiple lock bases are connected by a lock link, and the movement of the lock link drives the lock tongue to swing to achieve locking or unlocking of the lock shaft. In actual applications, the visual inspection device 10 photographs the end of the lock link to detect the locked or unlocked state of the battery pack 200.

[0051] like Figure 4As shown, each visual detection device 10 also includes a protective shell 3, which is connected to the battery exchange platform 20. The visual detection body 1 and the reflector 2 are both arranged in the protective shell 3. The incident light detected by the visual detection device 10 will pass through the protective shell 3 and irradiate the reflector 2. The protective shell 3 can protect the visual detection body 1 and the reflector 2, thereby improving the stability and reliability of the visual detection device 10. At the same time, the incident light will pass through the protective shell 3 and irradiate the reflector 2 in the protective shell 3, and the incident light will be reflected into the visual detection body 1 by the reflector 2.

[0052] The protective housing 3 has a sealed chamber in which the visual detection body 1 and the reflector 2 are both arranged. External impurities such as dust and water cannot enter the sealed chamber, which further strengthens the protection of the visual detection body 1 and the reflector 2 and improves the stability and reliability of the visual detection device 10.

[0053] The protective shell 3 includes a shell body and a transparent sheet. The bottom end of the shell body is connected to the battery exchange platform 20. The visual detection body 1 and the reflector 2 are both bonded to the shell body. The top of the shell body is provided with a light-transmitting port. The transparent sheet is sealed and connected to the shell body and is used to completely cover the light-transmitting port. The incident light detected by the visual detection device 10 will pass through the transparent sheet and the light-transmitting port and irradiate the reflector 2. The visual detection body 1 and the reflector 2 are both bonded to the shell body to facilitate the installation of the visual detection body 1 and the reflector 2 in the protective shell 3. At the same time, the protective shell 3 will pass through the transparent sheet and the light-transmitting port, so that the incident light will pass through the protective shell 3 and irradiate the reflector 2.

[0054] The transparent sheet is sealed and bonded to the shell body, thereby ensuring the sealing performance in the protective shell 3, and at the same time, the structure is simple and the connection is convenient. The transparent sheet can be made of glass, and the shell body can be made of stainless steel.

[0055] The two sides of the bottom end of the shell body have connecting plates extending outwards, and both connecting plates have a number of connecting holes, through which the shell body is connected to the power exchange platform 20. An installation connecting hole is provided at a predetermined position of the power exchange platform 20, and the fastener will pass through the connecting hole and be connected to the power exchange platform 20, so that the protective shell 3 is installed and set at a predetermined position of the power exchange platform 20, which is convenient for installation and connection and has high positioning accuracy.

[0056] The visual detection body 1 includes a visual lens 11, a signal processing unit 12 and an output line 13. The output line 13 is electrically connected to one end of the signal processing unit 12. The visual lens 11 is located between the other end of the signal processing unit 12 and the reflector 2. The light reflected by the reflector 2 will pass through the visual lens 11 and then project onto the signal processing unit 12. The light of the target to be detected will be reflected by the reflector 2, and the reflected light will pass through the visual lens 11. The image will be transmitted to the signal processing unit 12 through the visual lens 11. The signal processing unit 12 converts the image into an electrical signal, which is transmitted to the control system through the output line 13, so as to determine the locked or unlocked state of the battery pack 200. The structure is simple and the cost is low.

[0057] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
