[0006] Summary of the Invention

[0007] The present application provides a battery locking and unlocking device and system, which can effectively improve the convenience and efficiency of battery replacement.

[0008] In a first aspect, the present application provides a battery locking and unlocking device, comprising a locking and unlocking body, a prime mover, and a transmission device, wherein the locking and unlocking body is configured to lock or unlock the battery, the prime mover is configured to provide power to the locking and unlocking body, the transmission device is arranged between the locking and unlocking body and the prime mover, and there is a preset angle between the axis of the power output shaft of the prime mover and the rotation axis of the transmission device, and the preset angle is greater than 0° and less than 180°.

[0009] By setting the angle between the axis of the power output shaft of the prime mover and the rotation axis of the transmission device to be greater than 0° and less than 180°, the total length of the prime mover and the transmission device can be effectively reduced, thereby reducing the space occupied by the battery locking and unlocking device, thereby providing the possibility for the battery locking and unlocking device to enter the bottom of the vehicle to disassemble and assemble the battery without the vehicle rising, thereby reducing the waste of energy and time and improving the convenience and efficiency of battery replacement.

[0010] In some embodiments, the preset angle is 90°. This embodiment can further shorten the length of the battery locking and unlocking device, reduce the space occupied by the battery locking and unlocking device, and enable the battery to be removed and installed under the vehicle without the vehicle being lifted, thereby improving the convenience and efficiency of battery replacement.

[0011] In some embodiments, the rotation axis of the transmission mechanism is collinear with the rotation axis of the locking and unlocking body. This arrangement allows the height of the battery locking and unlocking device to be substantially equal to the combined height of the transmission mechanism and the locking and unlocking body, simplifies the transmission path between the transmission mechanism and the locking and unlocking body, and improves power transmission efficiency.

[0012] In some embodiments, the prime mover includes a motor. A motor has advantages such as small size, light weight, and high output. Using a motor as the prime mover helps reduce the overall size of the battery locking and unlocking device and reduces the space occupied by the battery locking and unlocking device.

[0013] In some embodiments, the transmission device includes a reducer. The reducer has the advantages of compact structure, small size and strong overload bearing capacity. The reducer has the function of matching the speed and transmitting the torque between the prime mover and the locking and unlocking body.

[0014] In a second aspect, the present application provides a battery locking and unlocking system, comprising the above-mentioned battery locking and unlocking device.

[0015] In some embodiments, the power output axis of the prime mover is arranged horizontally; and / or the rotation axis of the transmission device is arranged vertically, with the locking and unlocking body facing upward.

[0016] In some embodiments, the battery unlocking system includes a battery unlocking unit, which includes a mounting platform and multiple battery unlocking devices, each of which is mounted on the mounting platform. The mounting platform can be used to mount and support multiple battery unlocking devices.

[0017] In some embodiments, the battery locking and unlocking device is installed on a side of the mounting platform.

[0018] By installing the battery locking and unlocking device on the side of the mounting platform, the volume of the mounting platform can be minimized, thereby reducing the overall weight of the battery locking and unlocking system.

[0019] In some embodiments, the battery locking and unlocking system includes multiple battery locking and unlocking units, and a groove is provided on the side of the mounting platform. The groove is configured to allow the battery locking and unlocking devices in two adjacent battery locking and unlocking units to be arranged crosswise.

[0020] By setting the groove, the battery unlocking device of one of the two adjacent battery unlocking units can be inserted into the groove of the other battery unlocking unit, so as to improve the compactness of the battery unlocking system including multiple battery unlocking units, and at the same time avoid the inability to simultaneously remove and install two adjacently arranged batteries due to the distance between the two adjacent battery unlocking units being too far.

[0021] In some embodiments, the recess is configured to accommodate one or more battery locking and unlocking devices.

[0022] By setting the groove to accommodate one or more battery locking and unlocking devices, the layout of the battery locking and unlocking devices and the crossing mode of multiple battery locking and unlocking units can be enriched, thereby improving the layout flexibility of the battery locking and unlocking devices and battery locking and unlocking units.

[0023] In some embodiments, a plurality of battery locking and unlocking devices are respectively installed on both sides of the mounting platform, and grooves are provided on both sides of the mounting platform.

[0025] In some embodiments, the mounting platform is arranged horizontally, the locking and unlocking body is at least partially arranged above the mounting platform, and the prime mover and the transmission device are arranged below the mounting platform.

[0026] By setting the locking and unlocking body above the mounting platform and the prime mover and transmission device below the mounting platform, the distance between the mounting platform and the battery to be locked and unlocked can be effectively shortened, and the support effect of the mounting platform on the battery can be improved. For example, after the unlocking is completed, the battery can fall on the mounting platform more smoothly without falling or falling onto the mounting platform due to the large distance; at the same time, it can also facilitate the operation of the locking and unlocking body and prevent the prime mover or transmission device from interfering with the battery.

[0027] In some embodiments, the battery locking and unlocking system further includes a control device and a movable chassis, the battery locking and unlocking unit is installed on the chassis, and the control device is configured to control the chassis to move to the bottom of the battery to lock or unlock the battery.

[0028] By providing a control device and a movable chassis, the control device can control the chassis to drive the battery locking and unlocking unit to move to the bottom of the battery to lock or unlock the battery.

There is a preset angle between the axis of the power output shaft of the prime mover 2 and the rotation axis of the transmission device 3, and the preset angle is greater than 0° and less than 180°.

[0059] By setting the angle between the axis of the power output shaft of the prime mover 2 and the rotation axis of the transmission device 3 to be greater than 0° and less than 180°, the total length of the prime mover and the transmission device can be effectively reduced, thereby reducing the space occupied by the battery locking and unlocking device, thereby providing the possibility for the battery locking and unlocking device to enter the bottom of the vehicle to disassemble and assemble the battery without the vehicle rising, thereby reducing the waste of energy and time and improving the convenience and efficiency of battery replacement.

[0060] In some embodiments, the preset angle is 90°. This embodiment can further shorten the length of the battery locking and unlocking device 10 and reduce the space occupied by the battery locking and unlocking device 10, allowing the battery locking and unlocking device 10 to be inserted under the vehicle without the vehicle being lifted, thereby improving the convenience and efficiency of battery replacement.

[0061] In some embodiments, the rotation axis of the transmission device 3 is collinear with the rotation axis of the locking and unlocking body 1.

The multiple battery unlocking devices 10 are mounted on the mounting platform 20. By providing the mounting platform 20, multiple battery unlocking devices 10 can be mounted and supported.

[0069] In some embodiments, the battery locking and unlocking device 10 is installed on a side of the mounting platform 20 .

[0070] By installing the battery locking and unlocking device 10 on the side of the mounting platform 20 , the volume of the mounting platform 20 can be reduced as much as possible, thereby reducing the overall weight of the battery locking and unlocking system 1000 .

[0071] In some embodiments, a battery unlocking system 1000 includes multiple battery unlocking units 100. A groove 21 is provided on the side of a mounting platform 20. The groove 21 is configured to allow the battery unlocking devices 10 in two adjacent battery unlocking units 100 to be arranged crosswise. The groove 21 is recessed from one side of the mounting platform 20 toward the opposite side.

[0072] By providing the groove 21, the battery locking and unlocking device 10 of one battery locking and unlocking unit 100 of two adjacent battery locking and unlocking units 100 can be inserted into the groove 21 of the other battery locking and unlocking unit 100, so as to improve the compactness of the battery locking and unlocking system 1000 including multiple battery locking and unlocking units 100, and at the same time avoid the inability to simultaneously remove and install two adjacently arranged batteries due to the distance between the two adjacent battery locking and unlocking units 100 being too far.

[0073] In some embodiments, the recess 21 is configured to accommodate one or more battery locking and unlocking devices 10 .

[0074] By setting the groove 21 to accommodate one or more battery locking and unlocking devices 10, the arrangement of the battery locking and unlocking devices 10 and the crossing manner of multiple battery locking and unlocking units 100 can be enriched, thereby improving the arrangement flexibility of the battery locking and unlocking devices 10 and the battery locking and unlocking units 100.

[0075] In some embodiments, a plurality of battery locking and unlocking devices 10 are respectively installed on both sides of the mounting platform 20 , and grooves 21 are provided on both sides of the mounting platform 20 .

[0076] By providing the grooves 21 on both sides of the mounting platform 20 , both sides of the mounting platform 20 can be cross-arranged with the adjacent battery unlocking units 100 .

[0077] In some embodiments, the mounting platform 20 is arranged horizontally, the locking and unlocking body 1 is at least partially arranged above the mounting platform 20 , and the prime mover 2 and the transmission device 3 are arranged below the mounting platform 20 .

[0078] By setting the locking and unlocking body 1 above the mounting platform 20, and the prime mover 2 and the transmission device 3 below the mounting platform 20, the distance between the mounting platform 20 and the battery to be locked and unlocked can be effectively shortened, and the supporting effect of the mounting platform 20 on the battery can be improved. For example, after the unlocking is completed, the battery can fall on the mounting platform 20 more smoothly, and will not fall or fall onto the mounting platform 20 due to the large distance; at the same time, it can also facilitate the operation of the locking and unlocking body 1 and prevent the prime mover 2 or the transmission device 3 from interfering with the battery.

[0079] In some embodiments, the battery locking and unlocking system 1000 further includes a control device and a movable chassis. The battery locking and unlocking unit 100 is installed on the chassis. The control device is configured to control the chassis to move under the battery to lock or unlock the battery.

[0080] By providing a control device and a movable chassis, the control device can control the chassis to drive the battery locking and unlocking unit 100 to move to the bottom of the battery to lock or unlock the battery.

[0081] The structure of the battery locking and unlocking device and system provided by this application is described below with reference to Figures 2 to 5.

[0083] The prime mover 2 is a motor, and the transmission device 3 is a speed reducer. The power generated by the motor is transmitted via the speed reducer to the locking and unlocking body 1. Driven by the motor, the locking and unlocking body 1 rotates about its own axis, driving a screw member to rotate. This allows the battery to be installed on the vehicle, completing the locking operation; alternatively, the screw member can be removed from the battery and vehicle, completing the battery removal operation. The screw member can be a screw or bolt, etc.

[0084] In this embodiment, the axis of the power output shaft of the prime mover 2 is perpendicular to the rotation axis of the transmission device 3, and the rotation axis of the locking and unlocking body 1 is collinear with the rotation axis of the transmission device 3. This can significantly shorten the length of the battery locking and unlocking device 10 in the direction of the rotation axis of the locking and unlocking body 1, thereby reducing the space occupied by the battery locking and unlocking device 10, so that the battery locking and unlocking device 10 can enter the space under the vehicle to lock or unlock the battery without the vehicle rising.

[0085] As shown in Figure 4, the battery locking and unlocking unit 100 includes a mounting platform 20 and a plurality of battery locking and unlocking devices 10 mounted on the mounting platform 20.

[0089] Multiple battery locking and unlocking devices 10 installed on the same side can be arranged individually, or in groups of two, three, or more. The location and number of the battery locking and unlocking devices 10 on the mounting platform 20 match the location and number of the locking devices on the battery.

[0090] The six battery locking and unlocking devices 10 installed on the first side of the installation platform 20 and the six battery locking and unlocking devices 10 installed on the second side of the installation platform 20 are staggered, so that new battery locking and unlocking units 100 can be spliced ​​on both sides of the installation platform 20.

[0091] In the embodiment shown in Figure 5, the battery unlocking system 1000 includes three battery unlocking units 100, with two battery unlocking units 100 attached to either side of the central battery unlocking unit 100. The battery unlocking devices 10 on the adjacent sides of two adjacent battery unlocking units 100 are arranged in a staggered arrangement to reduce the distance between the two adjacent battery unlocking units 100, thus preventing the inability to lock or unlock both batteries simultaneously due to the excessive distance between the two adjacent battery unlocking units 100.

[0092] In other embodiments, the battery locking and unlocking system 1000 may include two, four or more battery locking and unlocking units 100 , and the splicing method is the same as that of the embodiment shown in FIG. 5 , which will not be described in detail here.
