[0030] The following is for reference. Figures 1 to 3 This invention describes a charging and swapping integrated device according to an embodiment of the present invention.

[0031] refer to Figures 1 to 3As shown, the charging and swapping integrated device according to an embodiment of the present utility model includes a charging pile 100, a charging box 200, and multiple swapping boxes 300.

[0032] The pile body 100 is used to support the charging box 200 and multiple battery swapping boxes 300. The bottom of the pile body 100 can be equipped with multiple casters for easy movement.

[0033] The charging box 200 can be installed at the top of the charging pile 100. The charging box 200 is provided with a first charging cable 201, and a first charging gun 202 is provided at the end of the first charging cable 201. In addition, the charging box 200 can also be provided with a power module, a control module and various other components. The power module converts the external AC power into DC power and delivers it to the first charging gun 202 through the first charging cable 201. The user's electric two-wheeled vehicle battery is provided with a corresponding socket. The first charging gun 202 is inserted into the socket to quickly charge the electric two-wheeled vehicle battery. The control module is used to control the operation of the charging and swapping integrated pile.

[0034] Multiple battery swapping boxes 300 are installed on the pile body 100. For example, there can be two, three, four, or other numbers of battery swapping boxes 300. The multiple battery swapping boxes 300 can be arranged vertically. A receiving cavity 301 is formed inside the battery swapping box 300. The front end of the battery swapping box 300 is provided with a pick-up and put-out port 302 and a door 303 for opening and closing the pick-up and put-out port 302. The door 303 can be rotatably or slidably installed in the battery swapping box 300, as long as it can open and close the pick-up and put-out port 302. A sliding plate 304 for carrying batteries is slidably installed at the bottom end of the receiving cavity 301. The sliding direction of the sliding plate 304 can be front and back. When the sliding plate 304 slides forward, it can pass through the pick-up and put-out port 302 and partially extend out of the receiving cavity 301. When the sliding plate 304 slides backward, it can be stored in the receiving cavity 301. A second charging cable 305 is connected to the outside of the battery swapping box 300. For example, the end of the second charging cable 305 away from the second charging gun 306 can be connected to the outside of the left side wall of the battery swapping box 300. The second charging cable 305 can be electrically connected to the power module. The battery swapping box 300 is provided with a clearance hole communicating with the receiving cavity 301. The second charging cable 305 passes through the clearance hole, and the end of the second charging cable 305 is provided with the second charging gun 306. The length of the second charging cable 305 can be greater than the distance between the position where the second charging cable 305 is connected to the battery swapping box 300 and the pick-up and drop-off port 302, so that the second charging gun 306 can move to pass through the pick-up and drop-off port 302 and be located outside the receiving cavity 301. In addition, when the second charging cable 305 moves from inside the receiving cavity 301 to outside the receiving cavity 301 along the clearance hole, the second charging cable 305 can be stored on the outside of the battery swapping box 300, thereby driving the second charging gun 306 to move to be located inside the receiving cavity 301.

[0035] In this invention, when a battery to be charged needs to be placed in the receiving cavity 301 of the battery swapping box 300 for charging, the door 303 is opened, and then the sliding plate 304 is slid outward so that the sliding plate 304 passes through the pick-up and put-out port 302 and extends out of the receiving cavity 301. The battery to be charged is placed on the sliding plate 304, and the second charging gun 306 is pulled so that the second charging gun 306 passes through the pick-up and put-out port 302 and is located outside the receiving cavity 301. The second charging gun 306 can then be inserted into the battery to be charged. Finally, the sliding plate 304, together with the battery to be charged, is slid together until it is stored in the receiving cavity 301. At the same time, the second charging cable 305 is gradually stored on the outside of the battery swapping box 300 so that the second charging gun 306 moves into the receiving cavity 301. The operation is simple and convenient. When a charged battery needs to be retrieved, slide the slide plate 304 outwards so that the charged battery on the slide plate 304 passes through the retrieval port 302 and extends out of the receiving cavity 301. At the same time, the second charging gun 306 moves along with it to pass through the retrieval port 302 and is located outside the receiving cavity 301. The second charging gun 306 can then be easily pulled out of the charged battery, and the charged battery can then be removed. The operation is simple and convenient.

[0036] It is understandable that existing charging and swapping integrated devices are prone to interference when removing and placing batteries because the size of the battery swapping box is generally only slightly larger than the size of the battery. In addition, interference is also likely to occur when the second charging gun 306 is plugged into or separated from the battery, resulting in troublesome operation and wasting time and effort. This application can effectively solve the above problems.

[0037] It should be noted that the pile body 100 may be provided with an installation groove, and the battery swapping box 300 may be installed in the installation groove. The outer side of the battery swapping box 300 refers to the space between the outer surface of the battery swapping box 300 and the inner surface of the installation groove. In other words, the second charging cable 305 can be stored in the space between the outer surface of the battery swapping box 300 and the inner surface of the installation groove, thereby moving the second charging gun 306 to the receiving cavity 301.

[0038] In some embodiments of this utility model, such as Figure 3As shown, a drive assembly 400 is provided on the outside of the battery swapping box 300. The drive assembly 400 is used to drive the second charging cable 305 to be stored on the outside of the battery swapping box 300. In this embodiment, the drive assembly 400 is provided so that when the second charging gun 306 is inserted into the battery to be charged on the slide plate 304 and the slide plate 304 slides inward to be stored in the receiving cavity 301, or when the second charging gun 306 is separated from the charged battery on the slide plate 304 and the slide plate 304 slides inward to be stored in the receiving cavity 301, the second charging cable 305 can be automatically stored on the outside of the battery swapping box 300 under the drive of the drive assembly 400, thereby moving the second charging gun 306 into the receiving cavity 301, without requiring the user to move the second charging cable 305, making it more convenient to use.

[0039] In some embodiments of this utility model, such as Figure 3 As shown, the drive assembly 400 includes a pulley 401 and a drive unit 402. The pulley 401 is slidably mounted on the outside of the battery swapping box 300. The second charging cable 305 is wound around the pulley 401. During the process of the second charging gun 306 moving to pass through the pick-up and put-out port 302 and being located outside the receiving cavity 301, the second charging cable 305 can drive the pulley 401 to slide in a first direction. The drive unit 402 is located on the outside of the battery swapping box 300 and connected to the pulley 401 to drive the pulley 401 to slide in the opposite direction of the first direction, so that the pulley 401 drives the second charging cable 305 to be stored on the outside of the battery swapping box 300. When the user pulls the second charging gun 306 from inside the receiving cavity 301 to pass through the pick-up and put-out port 302 and being located outside the receiving cavity 301, the second charging gun 306 drives the pulley 401 to slide in the first direction through the second charging cable 305, avoiding interference from the pulley 401 to the movement of the second charging gun 306. When the second charging gun 306 is inserted into the battery to be charged on the slide plate 304 and the slide plate 304 slides inward to be stored in the receiving cavity 301, or when the second charging gun 306 is separated from the charged battery on the slide plate 304 and the slide plate 304 slides inward to be stored in the receiving cavity 301, the drive unit 402 can drive the pulley 401 to slide in the opposite direction of the first direction. The pulley 401 thereby drives the second charging cable 305 to be stored on the outside of the battery swapping box 300, so that the second charging gun 306 automatically moves into the receiving cavity 301, making it more convenient to use.

[0040] It should be noted that the drive component 400 can also be other structures, such as a counterweight and a collar. The collar is fitted onto the second charging cable 305, and the counterweight is connected to the collar by a rope. Thus, under the gravity of the counterweight, the second charging cable 305 can be directly driven to be stored on the outside of the battery swapping box 300.

[0041] In some embodiments of this utility model, such as Figure 3As shown, the second charging cable 305 is connected to the outer side of the top of the side wall of the battery swapping box 300. A clearance hole is located at the top of the side wall of the battery swapping box 300. A pulley 401 is vertically slidably mounted on the outer side of the side wall of the battery swapping box 300. The second charging cable 305 is wound around the bottom of the pulley 401. The driving part 402 is used to drive the pulley 401 to slide downwards. With this configuration, when the pulley 401 slides upwards to the top of the side wall of the battery swapping box 300, the distance between the second charging cable 305 connected to the battery swapping box 300 and the pulley 401 is small, and the distance between the clearance hole and the pulley 401 is also small. This facilitates the user pulling the second charging gun 306 outwards, allowing the second charging gun 306 to move through the take-up / put-out port 302 and be located outside the receiving cavity 301. When the pulley 401 slides downwards to the bottom of the side wall of the battery swapping box 300, the distance between the position of the second charging cable 305 connected to the battery swapping box 300 and the pulley 401 is relatively large, and the distance between the clearance hole and the pulley 401 is also relatively large. This allows the second charging cable 305 to be quickly retracted to the outside of the battery swapping box 300, resulting in a good retraction effect for the second charging cable 305.

[0042] In some embodiments of this utility model, such as Figure 3 As shown, the drive assembly 400 also includes a mounting plate 403, which is disposed on the outer side of the side wall of the battery swapping box 300 and extends vertically. A pulley 401 is located between the mounting plate 403 and the side wall of the battery swapping box 300, and the two ends of the pulley 401 are slidably connected to the mounting plate 403 and the side wall of the battery swapping box 300, respectively. For example, the top and bottom ends of the mounting plate 403 can be provided with connecting plates and connected to the outer surface of the battery swapping box 300 through the connecting plates. In this embodiment, the pulley 401 is located between the mounting plate 403 and the side wall of the battery swapping box 300, so that the mounting plate 403 and the outer surface of the battery swapping box 300 can limit the second charging cable 305, so that the second charging cable 305 can always be wound around the pulley 401, thereby making the pulley 401 drive the second charging cable 305 to be stored on the outside of the battery swapping box 300 more effectively.

[0043] In some embodiments of this utility model, such as Figure 3As shown, the bottom end of the mounting plate 403 is provided with a connecting block 404. The mounting plate 403 is provided with a guide groove that extends vertically. The end of the pulley 401 away from the battery swapping box 300 is provided with a mounting shaft 405. The mounting shaft 405 passes through the pulley 401. The drive part 402 is configured as a tension spring and is located on the side of the mounting plate 403 away from the battery swapping box 300. The top end of the drive part 402 is connected to the mounting shaft 405, and the bottom end of the drive part 402 is connected to the connecting block 404. When the user pulls the second charging gun 306 from inside the receiving cavity 301 to outside the receiving cavity 301 through the take-up and put-out port 302, the second charging gun 306 drives the pulley 401 to slide to the top of the side wall of the battery swapping box 300 via the second charging cable 305. In this case, the tension spring extends and generates an elastic restoring force. When the second charging gun 306 is inserted into the battery to be charged on the slide plate 304 and the slide plate 304 slides inward to be stored in the receiving cavity 301, or when the second charging gun 306 is separated from the charged battery on the slide plate 304 and the slide plate 304 slides inward to be stored in the receiving cavity 301, the elastic restoring force of the tension spring can drive the pulley 401 to slide downward. The pulley 401 then drives the second charging cable 305 to be quickly stored on the outside of the battery swapping box 300. The structure is simple and easy to use, and the effect of driving the second charging cable 305 to be stored on the outside of the battery swapping box 300 is better. Furthermore, the drive unit 402 is located on the side of the mounting plate 403 away from the battery swapping box 300, which can prevent interference with the second charging cable 305.

[0044] It should be noted that the drive unit 402 can also be other structures; for example, the tension spring can be replaced with a rubber rope. Alternatively, a counterweight can be directly suspended from the mounting shaft 405, which will not be elaborated upon here.

[0045] In some embodiments of this utility model, such as Figure 3 As shown, a terminal block 307 is provided on the outer surface of the top of the side wall of the battery swapping box 300. The second charging cable 305 is connected to the terminal block 307, and a connecting portion 308 is formed at the end of the second charging cable 305 near the terminal block 307. The connecting portion 308 is connected to the side wall of the battery swapping box 300 by fasteners. The terminal block 307 can be electrically connected to the power module. In this embodiment, the connecting portion 308 can be integrally formed from the outer sleeve of the second charging cable 305. The connecting portion 308 is connected to the side wall of the battery swapping box 300 by fasteners. In this way, during the process of pulling the second charging gun 306 and the pulley 401 driving the second charging cable 305 to be stored outside the battery swapping box 300, the connecting portion 308 mainly bears the force, thereby avoiding the situation where the connection between the second charging cable 305 and the terminal block 307 is subjected to excessive force, which could cause poor contact or even damage to the terminal block 307.

[0046] In some embodiments of this utility model, such as Figure 3As shown, the inner wall of the receiving cavity 301 has an outwardly protruding receiving groove 309. The receiving groove 309 is located at the front end of the receiving cavity 301, and the front end of the receiving groove 309 is through-hole. When the second charging cable 305 is stored outside the battery swapping box 300, the second charging gun 306 is stored in the receiving groove 309. Thus, when the drive assembly 400 drives the second charging cable 305 to be stored outside the battery swapping box 300, the second charging gun 306 can be stored in the receiving groove 309. Since the receiving groove 309 protrudes outward, it can reduce the interference between the second charging gun 306 and the battery when they are both in the receiving cavity 301. Moreover, the receiving groove 309 is located at the front end of the receiving cavity 301, and the front end of the receiving groove 309 is through-hole, making it easier for the second charging gun 306 to be quickly stored in the receiving groove 309.

[0047] In some embodiments of this utility model, such as Figure 1 As shown, the charging pile 100 has an installation groove, and the battery swapping box 300 is installed in the installation groove. A storage space is formed between the outer surface of the battery swapping box 300 and the inner surface of the installation groove, and the second charging cable 305 can be stored in the storage space. This arrangement makes the storage effect of the second charging cable 305 better.

[0048] In some embodiments of this utility model, such as Figure 3 As shown, the slide plate 304 is provided with side plates 310 on both sides. The two ends of the side plates 310 along the sliding direction of the slide plate 304 are provided with slots 311 or holes. The side walls on both sides of the receiving cavity 301 are provided with spring beads 312. When the slide plate 304 slides to extend out of the receiving cavity 301 or is stored in the receiving cavity 301, at least one spring bead 312 is engaged in the slot 311 or hole to limit the slide plate 304 from continuing to slide.

[0049] During the sliding of the skateboard 304, the spring retainer 312 elastically contracts. When the skateboard 304 slides to extend out of the receiving cavity 301 or retract into the receiving cavity 301, at least one spring retainer 312 elastically extends and locks into the slot 311 or the hole, thereby restricting the skateboard 304 from continuing to slide. This prevents the skateboard 304 from sliding randomly during the battery removal and placement process, thus avoiding affecting the battery removal and placement, or the skateboard 304 from sliding randomly during the charging process, thus affecting the battery charging.

[0050] It should be noted that the spring-loaded retaining ball 312 includes a mounting cylinder, a spring, and a retaining ball. The mounting cylinder is located on the side walls of both sides of the receiving cavity 301, the spring is installed inside the mounting cylinder, and the retaining ball is connected to the spring. The spring-loaded retaining ball 312 is a common elastically retractable snap-fit ​​structure, which will not be described in detail here.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
