[0001] The present application relates to the field of battery charging technology, and in particular to a battery charging cabinet. Background Art

[0002] At present, in order to reduce the burden of workers carrying batteries that need to be replaced, more and more factories use battery carts to transport batteries. Battery carts can transport batteries to charging stations for charging. However, when the battery cart transports the battery to the charging station and docks it with the charging socket, the stability of the docking between the charging plug on the battery and the charging socket at the charging station fluctuates greatly. If the battery cart is subjected to a large force when entering the charging station, the battery cart is prone to collision and damage to the battery or the charging station. If the battery cart is subjected to a small force when entering the charging station, the force of the charging plug on the battery docking with the charging socket at the charging station is small, resulting in an unstable connection.

[0064] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0065] like Figures 1 to 3 As shown, this embodiment provides a battery charging cabinet 100, which is applied to a battery 20. The battery charging cabinet 100 can charge the battery 20. The battery 20 is configured with a mobile device 10, and the mobile device 10 can carry the battery 20 to move. The mobile device 10 can carry the battery 20 into or out of the battery charging cabinet 100, and can also carry the battery 20 to other places outside the battery charging cabinet 100. The mobile device 10 can be a trolley, which can be pushed or pulled by manpower to move. The mobile device 10 can also be an AGV (Automated Guided Vehicle) trolley, or an RGV (Rail Guided Vehicle) trolley, etc., to realize the automated movement of the mobile device 10.

[0066] The mobile device 10 includes a vehicle body 11 and rollers 12. The rollers 12 are rotatably mounted on the bottom end surface of the vehicle body 11, and are used to support and drive the vehicle body 11 to move. The number of rollers 12 can be four or six or other numbers, which is not specifically limited in this application. An empty slot 110 is provided on the top surface of the vehicle body 11, and the battery 20 is fixed in the empty slot 110, and the height of the battery 20 is higher than the depth of the empty slot 110, so that the top of the battery 20 is exposed in the empty slot 110. The battery 20 is provided with a power connection structure 21, and the power connection structure 21 is located on the outer surface of the portion of the battery 20 exposed in the empty slot 110, so as to facilitate docking with the battery charging cabinet 100.

[0067] It is understandable that in other embodiments, the battery 20 may not be equipped with the mobile device 10. The battery 20 may be placed in a material frame, and the material frame carries the battery 20 into or out of the battery charging cabinet 100.

[0068] For the convenience of subsequent reading, the present application introduces a first direction Y, a second direction X, and a third direction Z to describe the embodiments of the present application. The first direction Y, the second direction X, and the third direction Z may be three non-parallel linear directions in space; further, the first direction Y, the second direction X, and the third direction Z may be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction Y is the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction X is the X-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0069] The battery charging cabinet 100 includes a cabinet body 30 , a power transmission structure 40 , and a driving guide device 50 .

[0070] A charging slot 31 is formed on one side of the cabinet 30 along the first direction Y. The charging slot 31 is used to receive the mobile device 10 and the battery 20. The extension length of the charging slot 31 along the first direction Y is less than the extension length of the cabinet 30, so that the charging slot 31 has a bottom wall.

[0071] The power transmission structure 40 is arranged on the side wall of the charging slot 31. The power transmission structure 40 is used to be electrically connected to the power connection structure 21 of the battery 20 accommodated in the charging slot 31, so that a current channel is formed between the battery 20 and the cabinet 30, and the battery 20 is charged by the power supply device (not shown in the figure) arranged on the cabinet 30.

[0072] The driving guide device 50 is installed on the cabinet 30 and can be clamped on the opposite sides of the battery 20 along the second direction X. Along the second direction X, the inner walls on the opposite sides of the charging slot 31 are set as the first inner walls P1. The driving guide device 50 is installed at the two first inner walls P1 of the charging slot 31. The driving guide device 50 is configured to be able to slide relative to the battery 20 entering the charging slot 31, and is used to apply a driving force to the battery 20, and the driving force is used to drive the mobile device 10 to carry the battery 20 to approach or move away from the power transmission structure 40. In addition, when the battery 20 moves between the power connection structure 21 and the power transmission structure 40 to transmit electric energy, the driving force is also used to keep the position of the battery 20 unchanged to prevent charging interruption due to the movement of the battery 20.

[0073] It is understandable that, in some embodiments, the power connection structure 21 is a plug structure, and the power transmission structure 40 is a socket structure.

[0074] It is understandable that when other embodiments are adopted, the battery 20 can also be charged by wireless charging, instead of charging by docking the plug structure with the socket structure. At this time, the power connection structure 21 is a current receiving structure, and the power transmission structure 40 is a current transmitting structure. When the battery 20 enters the charging slot 31, the battery 20 moves to the current receiving structure and is located in the electromagnetic field formed by the current transmitting structure. The current receiving structure can receive the magnetic energy emitted by the current transmitting structure and convert it into electrical energy.

[0075] It is worth noting that the driving guide device 50 can be pre-tested by continuously adjusting the working parameters of the driving guide device 50 so that the driving guide device 50 applies different driving forces to the mobile device 10. When it is detected that the battery 20 and the cabinet 30 are best docked under a certain driving force, the working parameters of the driving guide device 50 under the driving force are recorded, and the subsequent driving guide device 50 works with the working parameters to ensure that the battery 20 that is charged can be docked stably each time.

[0076] In this way, the battery charging cabinet 100 of the present application, by setting a driving guide device 50 in the charging slot 31, when the mobile device 10 carrying the battery 20 enters the charging slot 31, the driving guide device 50 acts on the mobile device 10 to exert a force on it to continue moving forward. This not only saves effort for the person pushing the mobile device 10 into the charging slot 31, but also allows the driving guide device 50 to exert a relatively stable force on different mobile devices 10, ensuring that the battery 20 will not be damaged or the connection will be unstable when docking with the cabinet 30.

[0077] Please combine again Figure 3 and Figure 4In one embodiment, along the third direction Z, the charging slot 31 penetrates the bottom end surface of the cabinet 30, so that the entire cabinet 30 is roughly arranged in a "gantry" structure. In addition, along the third direction Z, the height of the charging slot 31 is greater than the total height of the mobile device 10 carrying the battery 20. The bottom end surface of the cabinet 30 is provided with supporting feet 32, and the number of the supporting feet 32 ​​is four or six.

[0078] The mobile device 10 carrying the battery 20 enters the slot of the charging slot 31 and continues to move forward until the power connection structure 21 of the battery 20 is connected to the power transmission structure 40 of the cabinet 30. The position of the power transmission structure 40 on the bottom wall of the charging slot 31 is set based on the position of the first electrical connection of the battery 20 entering the charging slot 31.

[0079] In particular, in some embodiments, both the power connection structure 21 and the power transmission structure 40 are provided with a magnetic attraction structure. The magnetic attraction structure is an electromagnet, which generates magnetism when energized, thereby facilitating the power connection structure 21 and the power transmission structure 40 to be quickly connected.

[0080] Please combine again Figures 3 to 6 In one embodiment, the number of the driving guide devices 50 is set to two, and the two driving guide devices 50 act on opposite sides of the mobile device 10 respectively to improve the stability of the driving guide device 50 when driving the mobile device 10 to move. Along the second direction X, the two first inner walls P1 of the charging slot 31 are both provided with mounting grooves 33, and the two driving guide devices 50 are respectively disposed in the mounting grooves 33.

[0081] Furthermore, the driving guide device 50 includes a driving member 51 and a guide stop assembly 52. ​​The driving member 51 is a power device such as an electric motor or a motor, and is installed in the installation slot 33.

[0082] The guide limit assembly 52 is rotatably connected to the cabinet 30 for rotating about the third direction Z. The driving member 51 is transmission-connected to the guide limit assembly 52 to drive the guide limit assembly 52 to rotate. At least a portion of the outer peripheral surface of the guide limit assembly 52 abuts against the side wall of the mobile device 10 entering the charging slot 31, so that when the guide limit assembly 52 rotates, the guide limit assembly 52 applies a driving force along the first direction Y to the mobile device 10, thereby driving the mobile device 10 to move.

[0083] Specifically, the guide limit assembly 52 includes at least two guide wheels 521, and the at least two guide wheels 521 are both connected to the driving member 51, and the driving member 51 simultaneously drives the at least two guide wheels 521 to rotate. Along the first direction Y, the at least two guide wheels 521 are arranged at intervals and can be rotatably received in the mounting groove 33.

[0084] The guide wheel 521 is a cylindrical structure, and the direction of the axis of the guide wheel 521 is parallel to the third direction Z. Along the third direction Z, the two opposite ends of the guide wheel 521 are convexly provided with first rotation shafts 5210, and the two first rotation shafts 5210 are rotatably connected to the groove walls on the upper and lower sides of the installation groove 33. Along the second direction X, the side of the guide wheel 521 away from the cabinet 30 is at least partially located outside the installation groove 33, so that at least part of the outer peripheral surface of the guide wheel 521 abuts against the side wall of the mobile device 10 entering the charging groove 31, so that the rotation of at least two guide wheels 521 jointly applies a driving force to the mobile device 10 to realize the forward or backward movement of the mobile device 10.

[0085] In particular, the driving member 51 can rotate forward or reverse to realize the forward or reverse rotation of the guide wheel 521 , thereby realizing the forward or backward movement of the mobile device 10 .

[0086] It can be understood that, in another embodiment, the guide and limiting assembly 52 further includes a conveyor belt 522 .

[0087] The conveyor belt 522 is sleeved on the outer circumference of at least two guide wheels 521, so that the conveyor belt 522 is driven to rotate by at least two guide wheels 521. At least part of the conveyor belt 522 is located outside the installation slot 33, so that at least part of the outer circumference of the conveyor belt 522 abuts against the side wall of the mobile device 10 entering the charging slot 31, and then the conveyor belt 522 applies a driving force to the mobile device 10 to realize the forward or backward movement of the mobile device 10.

[0088] Compared with the method of directly acting on the mobile device 10 through the guide wheel 521 , the use of the conveyor belt 522 can increase the magnitude of the force applied to the mobile device 10 .

[0089] Furthermore, the driving guide device 50 also includes a transmission assembly 53 , and the driving member 51 is transmission-connected to at least two guide wheels 521 via the transmission assembly 53 .

[0090] Specifically, the transmission assembly 53 includes at least two transmission wheels 531 and a transmission belt 532. The number of the transmission wheels 531 is the same as the number of the guide wheels 521, and each guide wheel 521 is provided with a transmission wheel 531. The transmission wheel 531 is fixed to the first rotating shaft 5210 located at the top of the guide wheel 521, and is coaxially arranged with the first rotating shaft 5210.

[0091] At least two transmission wheels 531 are transmission-connected to the transmission belt 532, and one transmission wheel 531 is transmission-connected to the driving member 51, so that the driving member 51 drives one transmission wheel 531 to rotate, and the transmission wheel 531 drives other transmission wheels 531 to rotate through the transmission belt 532, so that each transmission wheel 531 drives each guide wheel 521 connected thereto to rotate.

[0092] Please combine again Figure 3 to Figure 4 In one embodiment, the battery charging cabinet 100 further includes a guide device 60. Along the third direction Z, the guide device 60 is disposed on the second inner wall P2 of the charging slot 31. The guide device 60 is rotatably connected to the cabinet body 30 and can rotate around the second direction X. Along the third direction Z, the guide device 60 supports the battery 20 entering the charging slot 31 away from the side of the mobile device 10.

[0093] Further, the guide device 60 includes a mounting plate 61 and a pressure wheel 62. The mounting plate 61 is protruding from the second inner wall P2. Two connecting protrusions 611 are protruding from one end of the mounting plate 61 away from the second inner wall P2, and the two connecting protrusions 611 are arranged at intervals along the second direction X. The pressure wheel 62 is a cylindrical structure and is located between the two connecting protrusions 611. Second rotating shafts 621 are protruding from opposite ends of the pressure wheel 62 along the second direction X. The two second rotating shafts 621 are rotatably connected to the two connecting protrusions 611, respectively.

[0094] When the mobile device 10 carrying the battery 20 enters the charging slot 31 , the pressing wheel 62 presses against the side of the battery 20 away from the mobile device 10 to prevent the battery 20 from tilting when the driving guide device 50 drives the mobile device 10 to move.

[0095] Please combine again Figures 3 to 5 In one embodiment, the battery charging cabinet 100 further includes two guide plates 70, and the two guide plates 70 are roughly distributed in an "eight" shape. Along the second direction X, the two guide plates 70 are respectively arranged on the two first inner walls P1 of the charging slot 31, and along the first direction Y, the guide plates 70 are inclined from the end away from the power transmission structure 40 to the end close to the power transmission structure 40 toward the side away from the first inner wall P1 close to it. When the mobile device 10 enters the charging slot 31, the two guide plates 70 respectively abut against the opposite side walls of the mobile device 10, thereby guiding the mobile device 10 into the preset track to ensure smooth alignment of the power connection structure 21 and the power transmission structure 40.

[0096] Please combine again Figures 3 to 5 In one embodiment, the battery charging cabinet 100 further includes a heat dissipation component 80 , which is disposed on the cabinet body 30 and is used to blow air toward the battery 20 accommodated in the charging slot 31 .

[0097] Specifically, the heat dissipation assembly 80 includes a fan 81, and the number of the fans 81 is one or more. A top groove 34 is provided at the top of the cabinet 30, and the fan 81 is installed on the bottom wall of the top groove 34, and a vent 340 is provided on the bottom wall of the top groove 34, and the vent 340 is connected to the charging slot 31, and the air outlet of the fan 81 is arranged toward the vent 340, so that the fan 81 charges the battery 20 located in the charging slot 31 through the vent 340, so as to prevent the battery 20 from overheating during the charging process.

[0098] In particular, the opening cover of the top groove 34 is provided with a top plate 35, and the top plate 35 closes the top groove 34 to protect the fan 81 installed in the top groove 34. The top plate 35 is provided with a plurality of strip grooves so that airflow can enter the top groove 34.

[0099] In the above, the specific embodiments of the present application are described with reference to the accompanying drawings. However, those skilled in the art will appreciate that various changes and substitutions may be made to the specific embodiments of the present application without departing from the scope of the present application.
