[0034] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0036] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "connect", and "install" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Based on the background technology, the existing battery swap equipment can meet the disassembly and assembly requirements of batteries at different installation heights, but the overall structure of the equipment is relatively complex, occupies a large space and has high production costs. The utility model provides a locking and unlocking device for battery swap equipment, a battery swap equipment, and a battery swap station. By providing a suction cup and a suction seat that can adsorb each other, the sleeve and the drive device are fixed on the suction seat and can move in the vertical direction relative to the suction cup. The suction and separation of the suction cup and the suction seat realize the extension and retraction of the sleeve in the vertical direction to meet the disassembly and assembly requirements of vehicle batteries at different installation heights.

[0038] Specifically, Figures 1 to 3 As shown, the locking and unlocking device of the utility model comprises: a suction cup 1, which is fixed on the battery carrier and is provided with a first guide hole extending in the vertical direction, and a suction coil (not shown in the figure) is provided inside the suction cup 1, and the suction cup 1 can generate electromagnetic force by energizing the suction coil; a sleeve 2, which is inserted into the first guide hole and can move in the vertical direction along the first guide hole, and the top of the sleeve 2 can dock with the battery fixing bolt on the vehicle body to screw the battery fixing bolt; a driving device, which is arranged at the bottom of the sleeve 2 and drives the sleeve 2 connection to drive the sleeve 2 to rotate; an elastic component 4, both ends of the elastic component 4 are fixedly connected to the driving device and the sleeve 2 respectively, to realize the elastic connection between the sleeve 2 and the driving device in the vertical direction; a suction seat 5, the suction seat 5 is slidably connected under the suction cup 1, and can be sucked from the separation position to the suction position by the electromagnetic force generated by the suction cup 1, and can fall from the suction position to the separation position after the electromagnetic force disappears, and the bottom of the suction seat 5 is fixedly connected to the driving device to drive the driving device and the sleeve 2 to move relative to the suction cup 1 in the vertical direction, so as to realize the extension and retraction of the sleeve 2 on the locking and unlocking device.

[0039] Exemplarily, a plurality of battery swapping stations are provided in the battery swapping station, and a battery carrier is provided at the bottom of the battery swapping station. The battery carrier can automatically dock with the installation position of the vehicle battery, and the fixing bolts of the battery can be screwed through the locking and unlocking device to realize the disassembly and assembly of the battery and complete the rapid battery swapping.

[0040] Specifically, in a preferred battery replacement mode, when the vehicle enters the battery replacement station, the control system will control the battery carrier to move to the bottom of the vehicle and correspond to the installation position of the battery, and then control the unlocking device to rise to connect with the battery fastening bolts, and twist the battery fixing bolts by rotating them, so as to unlock the battery fixing bolts to remove the low-charged battery from the vehicle body, and then transfer the low-charged battery to the charging compartment for charging through the transmission mechanism (such as transmission wheels, transmission belts, etc.). At the same time when the low-charged battery leaves the battery carrier, the system will transfer a fully charged battery to the battery carrier, and the battery carrier will send the fully charged battery into the battery compartment on the vehicle body, and then control the unlocking device to install the battery fixing bolts into the screw holes and tighten them, thereby completing the battery replacement process of the vehicle. This process usually only takes about 3 minutes.

[0041] Since the installation heights of batteries and battery fixing bolts are different on different models, it is often necessary to adjust the height of the locking and unlocking device to complete the docking with the battery fixing bolts during the locking and unlocking process of the battery fixing bolts. The utility model utilizes the magnetic suction principle to achieve the extension and retraction of the sleeve 2 and the adjustment of the height. Specifically, the suction cup 1 is configured as a disc-shaped structure or a cylindrical structure, the first guide hole is coaxially arranged with the suction cup 1 and passes through the upper and lower surfaces of the suction cup 1 in the vertical direction, the suction coil is arranged around the first guide hole in the suction cup 1, and is connected to an external power supply to form a loop.

[0042] The suction seat 5 below can be set as an iron block or a permanent magnet block. The driving device and the sleeve 2 are both installed on the suction seat 5 and can move synchronously with the suction seat 5. The suction seat 5 has two working positions: the suction position and the separation position. When the suction coil in the suction cup 1 is energized, magnetic force will be generated, which can suck the suction seat 5 from the separation position to the suction position, and at the same time drive the sleeve 2 to move upward, so as to achieve the extension of the sleeve 2 on the locking and unlocking device to meet the locking and unlocking requirements of the battery fixing bolts with a higher installation position; when the suction coil in the suction cup 1 is de-energized, the suction seat 5 will be separated from the suction cup 1 and move downward to the separation position under the action of gravity, and at the same time drive the sleeve 2 to move downward, so as to achieve the shortening of the locking and unlocking device to meet the locking and unlocking requirements of the lower fixing bolts.

[0043] The driving device is connected to the bottom of the sleeve 2 to drive the sleeve 2 to rotate. At the same time, the driving device and the sleeve 2 are also elastically connected in the vertical direction through an elastic component 4 (such as a coil spring, etc.) so that during the locking and unlocking process, the sleeve 2 and the battery fixing bolts are pressed by the elastic component 4, which helps to absorb the vibration generated by the locking and unlocking device, reduce the impact of the vibration on the vehicle body, make the battery replacement process quieter, and enhance the battery replacement experience of users in the car.

[0044] For example, Figure 4 As shown, the bottom of the sleeve 2 is sleeved on the output end of the driving device and can move in the vertical direction relative to the output end of the driving device. A strip-shaped limit hole extending in the vertical direction is also provided on the output end of the driving device, and a circular limit hole is provided at a corresponding position on the sleeve 2. The limit pin 34 is simultaneously inserted into the circular limit hole and the strip-shaped limit hole, which can not only limit the relative rotation between the sleeve 2 and the driving device, so that the two can rotate synchronously to realize the transmission of torque, but also ensure the axial movement of the sleeve 2 relative to the driving device, so as to realize the absorption of vibration through the elastic component 4.

[0045] To sum up, the locking and unlocking device configured in this way, on the one hand, when locking and unlocking the battery bolt installed at a higher position, can utilize the power of the attraction coil to enable the suction cup 1 to generate electromagnetic force, so as to attract the attraction seat 5 upward from the separation position to the attraction position, thereby driving the driving device and the sleeve 2 to move upward synchronously, so as to achieve the extension of the sleeve 2 on the locking and unlocking device to adapt to vehicles of different heights, thereby improving the compatibility of the locking and unlocking device; on the other hand, after the sleeve 2 is combined with the bolt and the elastic member 4 is in a compressed state, the attraction seat 5 is separated downward from the suction cup 1 by de-energizing the attraction coil, which helps to release part of the elastic potential energy in the elastic member 4, reduce the compression force of the elastic member 4 on the sleeve 2 and the vehicle body, and make the energy absorption and shock-absorbing effects of the elastic member 4 more effective, thereby reducing the noise and vibration generated by the sleeve 2 and the bolt during the locking and unlocking process, thereby improving the user's battery replacement experience; on the other hand, compared with the traditional lifting mechanism, the structure of the battery replacement equipment is simplified, the equipment volume is reduced, and the equipment cost is reduced.

[0046] Preferably, if Figure 1 and Figure 2 As shown, the suction cup 1 of the utility model also includes a permanent magnet (not shown in the figure) and a separation coil (not shown in the figure). The permanent magnet can maintain the suction force on the suction seat 5 after the suction coil is powered off, and the separation coil can generate a magnetic field opposite to that of the permanent magnet after being powered on to release the suction force of the suction cup 1 on the suction seat 5.

[0047] For example, when facing a battery fixing bolt installed at a higher position, it is necessary to energize the suction coil so that the suction cup 1 generates a sufficiently large suction force to suck the suction seat 5 from the separation position to the suction position, thereby realizing the rise of the sleeve 2. After the suction cup 1 and the suction seat 5 are attracted to each other, the power supply of the suction coil can be disconnected. At this time, only the suction force of the permanent magnet is sufficient to keep the suction seat 5 and the suction cup 1 in the attracted state, so as to ensure that the height of the sleeve 2 is maintained. In the process of unlocking the battery fixing bolt, as the battery fixing bolt is gradually As it descends, the elastic member 4 is pressed tighter and tighter until the driving device and the sleeve 2 are almost hard-connected, so that the noise and vibration generated by the locking and unlocking device will be clearly transmitted to the vehicle body, causing the noise and vibration to intensify. At this time, the separation coil can be energized to generate a magnetic field opposite to that of the permanent magnet to release the suction force of the suction cup 1 on the suction seat 5, thereby separating the suction seat 5 from the suction cup 1, and then releasing the elastic potential energy accumulated in the elastic member 4, reducing the pressing force of the elastic member 4 on the sleeve 2 and the vehicle body, so that it can play the role of energy absorption and shock absorption.

[0048] Therefore, the attraction coil is only responsible for applying upward suction to the attraction seat 5, the permanent magnet is only responsible for keeping the attraction coil closed after power is cut off, and the separation coil is only responsible for offsetting the magnetism of the permanent magnet to separate the attraction seat 5 from the suction cup 1. In this way, each coil can operate independently and the operating time can be controlled, avoiding high temperature caused by the coil being energized for too long and preventing damage to the coil or power supply.

[0049] It should be noted that the voltage loaded on the attraction coil and the separation coil and the magnetic force generated by the permanent magnet can be flexibly set according to the total weight of the attraction seat 5, the sleeve 2 and the driving device. As long as the attraction and separation of the attraction seat 5 can be achieved, this case is not specifically limited here.

[0050] Preferably, if Figures 1 to 4 As shown, the locking and unlocking device of the utility model includes a plurality of adjusting bolts 6 installed in the vertical direction at the bottom of the suction cup 1, and a plurality of limiting holes slidably matched with the adjusting bolts 6 are arranged at corresponding positions on the suction seat 5. The adjusting bolts 6 are passed through the limiting holes to realize the sliding connection between the suction seat 5 and the suction cup 1. The bottom of the adjusting bolt 6 is provided with a limiting cap 61, which can limit the downward movement of the suction seat 5, and the adjusting bolt 6 can adjust the distance between the limiting cap 61 and the suction cup 1 by rotating.

[0051] Exemplarily, a plurality of adjusting bolts 6 are arranged at intervals along the circumference at the bottom edge of the suction cup 1. The number can be flexibly set as needed. In this case, it is preferably set to six. The adjusting bolts 6 are connected to the threaded holes at the bottom of the suction cup 1 through the external threads set at the top. The limit cap 61 is located at the bottom of the adjusting bolt 6. The suction seat 5 is slidably installed on the adjusting bolt 6. By rotating the adjusting bolt 6, the length of the part of the adjusting bolt 6 exposed outside the suction cup 1 (i.e., the distance between the suction position and the separation position) can be changed, thereby being able to adjust the maximum telescopic length of the sleeve 2.

[0052] It should be noted that, in practical applications, those skilled in the art can flexibly set the adjustment range of the bolt, which is preferably set between 10 cm and 20 cm in this case, so as to take into account both the adjustment height of the sleeve 2 and the adsorption capacity of the suction cup 1.

[0053] Preferably, if Figures 1 to 4 As shown, the locking and unlocking device of the utility model also includes a plurality of guide rods 7 fixed at the bottom of the suction cup 1 in the vertical direction, and a plurality of second guide holes slidably matched with the guide rods 7 are also provided at corresponding positions on the suction seat 5, and the guide rods 7 are inserted into the second guide holes to limit and guide the suction seat 5.

[0054] Illustratively, multiple guide rods 7 and multiple adjusting bolts 6 are alternately arranged, which can guide and limit the movement of the suction seat 5 in the vertical direction, further improving the stability of the suction seat 5 during movement, ensuring the axial accuracy of the sleeve 2 at different height positions, and making the sleeve 2 more accurately docked with the battery bolts.

[0055] Preferably, if Figures 1 to 4 As shown, the driving device of the utility model includes a driving motor 31 and a mounting seat 32. The driving motor 31 is mounted at the bottom of the mounting seat 32, and the output end of the driving motor 31 is drivingly connected to the sleeve 2. The mounting seat 32 is used to support and fix the driving motor 31, thereby improving the installation stability of the driving motor 31 and the stability of the power output.

[0056] Preferably, if Figures 1 to 4 As shown, the driving device of the utility model further includes a reducer 33 mounted on the top of the mounting seat 32 , the input end of the reducer 33 is drivingly connected to the output end of the driving motor 31 , and the output end of the reducer 33 is drivingly connected to the sleeve 2 .

[0057] The speed reducer 33 reduces the speed of the power output by the driving motor 31 and increases the torque, thereby increasing the torque of the sleeve 2 and making the locking and unlocking process easier.

[0058] Preferably, if Figures 1 to 3 As shown, a plurality of grooves 51 extending in the radial direction are further provided on the top surface of the suction seat 5 of the utility model, and the plurality of grooves 51 are distributed at intervals in the circumferential direction.

[0059] For example, when replacing the battery in rainy or snowy weather or when the vehicle has just been washed, the accumulated water on the vehicle body will flow into the interior of the locking and unlocking device through the first guide hole, and there is a risk of flowing into the driving device. The groove 51 can discharge the water flowing from the vehicle body to the top of the suction seat 5 in time to prevent the water from seeping in and damaging the equipment. In this scheme, three grooves 51 are preferably provided for drainage.

[0060] Preferably, if Figures 1 to 4 As shown, the sleeve 2 of the present invention is detachably drivingly connected to the driving device.

[0061] Exemplarily, the connection and separation of the sleeve 2 and the drive device can be achieved by plugging and pulling out the limit pin 34, thereby realizing the rapid disassembly and replacement of the sleeve 2, which can not only enable the damaged sleeve 2 to be quickly replaced, but also facilitate the rapid replacement of sleeves 2 of different shapes to adapt to different types of bolts, such as round, hexagonal, plum blossom, etc.

[0062] In addition, the setting of the groove 51 also facilitates the insertion and removal of the limit pin 34. It only needs to adjust the position of the groove 51 to the same height as the limit pin 34 so that the groove 51 is directly opposite the limit pin 34, thereby facilitating the connection and separation of the sleeve 2 and the drive device.

[0063] In addition, the battery exchange equipment further provided by the utility model on the basis of the above-mentioned locking and unlocking device has the technical effects of the above-mentioned locking and unlocking device due to the adoption of the above-mentioned locking and unlocking device.
