[0005] This application provides a battery locking and unlocking device and system, which can effectively improve the convenience and efficiency of battery replacement.

[0006] In a first aspect, this application provides a battery locking and unlocking device, including a locking and unlocking body, a prime mover, and a transmission device. 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. The preset angle is greater than 0° and less than 180°.

[0007] 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 occupied space of the battery locking and unlocking device, and providing the possibility for the battery locking and unlocking device to enter below 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.

[0008] In some embodiments, the preset angle is 90°. This embodiment can further shorten the length of the battery locking and unlocking device, reduce the occupied space of the battery locking and unlocking device, enable the battery locking and unlocking device to enter below the vehicle to perform the operation of disassembling and assembling the battery without the vehicle rising, and improve the convenience and efficiency of battery replacement.

[0009] In some embodiments, the rotation axis of the transmission device is collinear with the rotation axis of the locking and unlocking body. Such an arrangement can make the height of the battery locking and unlocking device basically the total height of the transmission device and the locking and unlocking body, and can simplify the transmission path between the transmission device and the locking and unlocking body, improving the power transmission efficiency.

[0010] In some embodiments, the prime mover includes an electric motor. The electric motor has the advantages of small volume, light weight, and large output. Using the electric motor as the prime mover helps to reduce the overall volume of the battery locking and unlocking device and the occupied space of the battery locking and unlocking device.

[0011] In some embodiments, the transmission device includes a speed reducer. The speed reducer has the advantages of compact structure, small volume, and strong overload-bearing capacity. The speed reducer plays a role in matching the rotational speed and transmitting torque between the prime mover and the locking and unlocking body.

[0012] In a second aspect, the present application provides a battery locking and unlocking system, including the above-mentioned battery locking and unlocking device.

[0013] In some embodiments, the power output axis of the prime mover is horizontally arranged; and / or, the rotation axis of the transmission device is vertically arranged, and the locking and unlocking body is arranged upward.

[0014] In some embodiments, the battery locking and unlocking system includes a battery locking and unlocking unit, and the battery locking and unlocking unit includes a mounting platform and a plurality of battery locking and unlocking devices, and the plurality of battery locking and unlocking devices are mounted on the mounting platform. By providing the mounting platform, a plurality of battery locking and unlocking devices can be mounted and supported.

[0015] In some embodiments, the battery locking and unlocking device is mounted on the side of the mounting platform.

[0016] By mounting 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.

[0017] In some embodiments, the battery locking and unlocking system includes a plurality of battery locking and unlocking units, and a groove is provided on the side of the mounting platform, and the groove is configured to cross-arrange the battery locking and unlocking devices in two adjacent battery locking and unlocking units.

[0018] By providing the groove, the battery locking and unlocking device of one battery locking and unlocking unit in two adjacent battery locking and unlocking units can be inserted into the groove of the other battery locking and unlocking unit, so as to improve the compactness of the battery locking and unlocking system including a plurality of battery locking and unlocking units, and at the same time, it can be avoided that the two adjacent battery locking and unlocking units are too far apart to disassemble and install two adjacent batteries simultaneously.

[0019] In some embodiments, the groove is configured to accommodate one or more battery locking and unlocking devices.

[0020] By configuring the groove to be able to accommodate one or more battery locking and unlocking devices, the arrangement forms of the battery locking and unlocking devices and the crossing modes of multiple battery locking and unlocking units can be enriched, and the layout flexibility of the battery locking and unlocking devices and the battery locking and unlocking units can be improved.

[0021] In some embodiments, multiple battery locking and unlocking devices are respectively installed on both sides of the installation platform, and grooves are provided on both sides of the installation platform.

[0022] By respectively providing grooves on both sides of the installation platform, both sides of the installation platform can be cross-arranged with adjacent battery locking and unlocking units.

[0023] In some embodiments, the installation platform is horizontally arranged, the locking and unlocking body is at least partially arranged above the installation platform, and the prime mover and the transmission device are arranged below the installation platform.

[0024] By arranging the locking and unlocking body above the installation platform and arranging the prime mover and the transmission device below the installation platform, the distance between the installation platform and the battery to be locked and unlocked can be effectively shortened, and the supporting effect of the installation platform on the battery can be improved. For example, after unlocking, the battery can fall more stably on the installation platform without falling or dropping onto the installation platform due to too large a distance; at the same time, it is also convenient for the locking and unlocking body to work and prevent the prime mover or the transmission device from interfering with the battery.

[0025] In some embodiments, the battery locking and unlocking system further includes a control device and a walkable chassis. The battery locking and unlocking unit is installed on the chassis, and the control device is configured to control the chassis to move under the battery to lock or unlock the battery.

[0048] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0049] The capacity of the battery is limited and the power supply time is limited. Therefore, the battery needs to be replaced during long-distance travel. The disassembly and installation method of the battery affects the convenience and efficiency of battery replacement.

[0050] In the related art, in order to more conveniently disassemble the dead battery and install the fully charged battery, the vehicle is usually lifted to a certain height, and then it is convenient for personnel or equipment to perform disassembly and installation operations under the vehicle.

[0051] After the vehicle is lifted to a certain height and then the battery is disassembled and installed, although it can provide a larger operating space for the equipment and personnel, lifting the vehicle not only consumes energy but also wastes time.

[0052] Based on the above considerations, the structure of the battery locking and unlocking device in the present application is improved. In the battery locking and unlocking device provided in the present application, it includes a locking and unlocking body, a prime mover, and a transmission device.

Among them, the included angle between the axis of the power output shaft of the prime mover and the axis of rotation of the transmission device is greater than 0° and less than 180°.

[0053] Compared with the scheme where the axis of the power output shaft of the prime mover is parallel to the axis of rotation of the transmission device, the technical scheme provided in the present application can reduce the total length of the prime mover and the transmission device, thereby reducing the occupied space of the battery locking and unlocking device, and thus providing the possibility for the battery locking and unlocking device to enter under the vehicle to disassemble and install the battery without lifting the vehicle, thereby reducing the waste of energy and time and improving the convenience and efficiency of battery replacement.

[0054] The battery unlocking and locking device disclosed in the embodiments of the present application can be but is not limited to being used in electrical equipment such as vehicles, ships, or aircraft.

[0055] For the convenience of description in the following embodiments, a vehicle 10a, which is an electrical equipment in an embodiment of the present application, is taken as an example for illustration.

[0056] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of the vehicle 10a provided in some embodiments of the present application. The vehicle 10a can be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc. A battery 1a is disposed inside the vehicle 10a, and the battery 1a can be disposed at the bottom, head, or tail of the vehicle 10a. The battery 1a can be used for power supply of the vehicle 10a. For example, the battery 1a can be used as the operating power source of the vehicle 10a. The vehicle 10a may further include a controller 2a and a motor 3a. The battery 1a is used to provide electrical energy for the operation of the motor 3a and other components in the vehicle.

Generally, the battery 1a is divided into three types according to the encapsulation method: cylindrical battery monomers, square battery monomers, and soft-pack battery monomers. The embodiments of the present disclosure do not limit this either.

[0059] Next, with reference to the attached Figure 2 and 3 , the structure of the embodiments of the battery unlocking and locking device 10 provided by the present application will be introduced.

[0060] As Figure 2 and Figure 3 shown, in an embodiment of the battery locking and unlocking device 10 provided in the present application, the battery locking and unlocking device 10 includes a locking and unlocking body 1, a prime mover 2, and a transmission device 3. The locking and unlocking body 1 is configured to lock or unlock the battery. The prime mover 2 is used to provide power. The transmission device 3 is disposed between the locking and unlocking body 1 and the prime mover 2, and 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. The preset angle is greater than 0° and less than 180°.

[0061] 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 occupied space of the battery locking and unlocking device, and providing the possibility for the battery locking and unlocking device to enter below 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.

[0062] In some embodiments, the preset angle is 90°. This embodiment can further shorten the length of the battery locking and unlocking device 10, reduce the occupied space of the battery locking and unlocking device 10, so that the battery locking and unlocking device 10 can enter below the vehicle to perform the operation of disassembling and assembling the battery without the vehicle rising, and improve the convenience and efficiency of battery replacement.

[0063] In some embodiments, the rotation axis of the transmission device 3 is collinear with the rotation axis of the locking and unlocking body 1. Such a setting can make the height of the battery locking and unlocking device 10 basically the total height of the transmission device 3 and the locking and unlocking body 1, and can simplify the transmission path between the transmission device 3 and the locking and unlocking body 1, and improve the power transmission efficiency.

[0064] In some embodiments, the prime mover 2 includes an electric motor. The electric motor has the advantages of small volume, light weight, and large output. Using the electric motor as the prime mover 2 helps to reduce the overall volume of the battery locking and unlocking device 10 and reduce the occupied space of the battery locking and unlocking device 10.

[0065] In some embodiments, the transmission device 3 includes a reducer. The reducer has the advantages of compact structure, small volume, and strong overload capacity. The reducer has the function of matching the speed and transmitting the torque between the prime mover 2 and the locking and unlocking body 1.

[0066] The battery locking and unlocking device 10 provided by the embodiments of the present application can be used for various electrical equipment equipped with batteries.

[0067] The following combines the attached Figure 4 and 5, the structure of the battery locking and unlocking system 1000 embodiment provided by the present application will be introduced.

[0068] As Figure 4 shown, the battery locking and unlocking system 1000 includes the above-mentioned battery locking and unlocking device 10.

[0069] As Figure 2 shown, in some embodiments, the power output axis of the prime mover 2 is horizontally arranged; and / or, the rotation axis of the transmission device 3 is vertically arranged, and the locking and unlocking body 1 is arranged upward. Such a setting can facilitate the locking or unlocking operation of the battery by the battery locking and unlocking device under the vehicle.

[0070] In some embodiments, the battery locking and unlocking system 1000 includes a battery locking and unlocking unit 100. The battery locking and unlocking unit 100 includes a mounting platform 20 and a plurality of battery locking and unlocking devices 10. The plurality of battery locking and unlocking devices 10 are mounted on the mounting platform 20. By providing the mounting platform 20, a plurality of battery locking and unlocking devices 10 can be installed and supported.

[0071] In some embodiments, the battery locking and unlocking device 10 is mounted on the side of the mounting platform 20.

[0072] By mounting the battery locking and unlocking device 10 on the side of the mounting platform 20, the volume of the mounting platform 20 can be minimized, thereby reducing the overall weight of the battery locking and unlocking system 1000.

[0073] In some embodiments, the battery locking and unlocking system 1000 includes a plurality of battery locking and unlocking units 100. A groove 21 is provided on the side of the mounting platform 20. The groove 21 is configured to cross-arrange the battery locking and unlocking devices 10 in two adjacent battery locking and unlocking units 100. The groove 21 recesses from one side of the mounting platform 20 to the other side opposite thereto.

[0074] By providing the groove 21, the battery locking and unlocking device 10 of one battery locking and unlocking unit 100 in 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 a plurality of battery locking and unlocking units 100, and at the same time, it can be avoided that the two adjacent battery locking and unlocking units 100 are too far apart to disassemble and install two adjacent batteries at the same time.

[0075] In some embodiments, the groove 21 is configured to accommodate one or more battery locking and unlocking devices 10.

[0076] By arranging the groove 21 to accommodate one or more battery unlocking and locking devices 10, the arrangement forms of the battery unlocking and locking devices 10 and the crossing modes of multiple battery unlocking and locking units 100 can be enriched, and the arrangement flexibility of the battery unlocking and locking devices 10 and the battery unlocking and locking units 100 can be improved.

[0077] In some embodiments, multiple battery unlocking and locking devices 10 are respectively installed on both sides of the installation platform 20, and grooves 21 are provided on both sides of the installation platform 20.

[0078] By respectively arranging the grooves 21 on both sides of the installation platform 20, cross-arrangement can be achieved between both sides of the installation platform 20 and the adjacent battery unlocking and locking units 100.

[0079] In some embodiments, the installation platform 20 is horizontally arranged, at least part of the unlocking and locking body 1 is arranged above the installation platform 20, and the prime mover 2 and the transmission device 3 are arranged below the installation platform 20.

[0080] By arranging the unlocking and locking body 1 above the installation platform 20 while arranging the prime mover 2 and the transmission device 3 below the installation platform 20, the distance between the installation platform 20 and the battery to be unlocked and locked can be effectively shortened, and the supporting effect of the installation platform 20 on the battery can be improved. For example, after unlocking, the battery can fall more stably on the installation platform 20 without falling or crashing onto the installation platform 20 due to too large a distance. At the same time, it is also convenient for the unlocking and locking body 1 to work and prevent the prime mover 2 or the transmission device 3 from interfering with the battery.

[0081] In some embodiments, the battery unlocking and locking system 1000 further includes a control device and a walkable chassis. The battery unlocking and locking unit 100 is installed on the chassis, and the control device is configured to control the chassis to move under the battery to lock or unlock the battery.

[0082] By providing a control device and a walkable chassis, the control device can be used to control the chassis to drive the battery unlocking and locking unit 100 to move under the battery to lock or unlock the battery.

[0083] The following combines the attached Figures 2 to 5 to illustrate the structure of the battery unlocking and locking device and system provided in this application.

[0084] In the embodiments as Figure 2 and Figure 3 shown, the battery unlocking and locking device 10 includes an unlocking and locking body 1, a prime mover 2, and a transmission device 3. The transmission device 3 is connected between the unlocking and locking body 1 and the prime mover 2.

[0085] The prime mover 2 uses an electric motor, and the transmission device 3 uses a speed reducer. The power generated when the electric motor works is transmitted to the locking and unlocking body 1 through the speed reducer. The locking and unlocking body 1 rotates around its own axis under the driving action of the electric motor, and can drive the screwing member to rotate, so as to install the battery on the vehicle through the screwing member, realizing the installation of the battery, that is, completing the locking operation; or, disassembling the screwing member from the battery and the vehicle, realizing the disassembly of the battery, that is, completing the unlocking operation. The screwing member can be a screw or a bolt, etc.

[0086] In this embodiment, the axis of the power output shaft of the prime mover 2 is perpendicular to the axis of rotation of the transmission device 3, and the axis of rotation of the locking and unlocking body 1 is collinear with the axis of rotation of the transmission device 3, which can significantly shorten the length of the battery locking and unlocking device 10 in the direction of the axis of rotation of the locking and unlocking body 1, and further reduce the occupied space of the battery locking and unlocking device 10, so that the battery locking and unlocking device 10 can enter the space below the vehicle to lock or unlock the battery without the vehicle rising.

[0087] As Figure 4 shown, the battery locking and unlocking unit 100 includes an installation platform 20 and a plurality of battery locking and unlocking devices 10 installed on the installation platform 20. Moreover, the battery locking and unlocking devices 10 installed on both sides of the installation platform 20 are arranged staggeredly.

[0088] In the embodiment as Figure 4 shown, 12 battery locking and unlocking devices 10 are installed on the installation platform 20, and 6 battery locking and unlocking devices 10 are installed on each side of the installation platform 20.

[0089] Six battery locking and unlocking devices 10 are installed on the first side of the installation platform 20, and six battery locking and unlocking devices 10 are also installed on the second side of the installation platform 20. The first side and the second side are arranged oppositely. The installation platform 20 is strip-shaped, and the first side and the second side extend along the length direction.

[0090] A plurality of grooves 21 are provided on both the first side and the second side of the installation platform 20. One or more battery locking and unlocking devices 10 in another battery locking and unlocking unit 100 can be accommodated in the grooves 21.

[0091] The plurality of battery locking and unlocking devices 10 installed on the same side can be arranged at intervals individually, or two, three or more battery locking and unlocking devices 10 can be arranged at intervals in groups. The installation positions and quantities of the battery locking and unlocking devices 10 on the installation platform 20 match the installation positions and quantities of the locking devices on the battery.

[0092] Six battery locking and unlocking devices 10 installed on the first side of the installation platform 20 and 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 respectively.

[0093] In the embodiment as Figure 5 shown, the battery locking and unlocking system 1000 includes three battery locking and unlocking units 100, and one battery locking and unlocking unit 100 is spliced on each side of the battery locking and unlocking unit 100 located in the middle. The battery locking and unlocking devices 10 on the sides of two adjacent battery locking and unlocking units 100 that are close to each other are arranged crosswise to reduce the distance between the two adjacent battery locking and unlocking units 100 and avoid being unable to lock or unlock two batteries simultaneously due to too large a distance between the two adjacent battery locking and unlocking units 100.

[0094] 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 as Figure 5 shown, which will not be elaborated here.

[0095] Although the present application has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
