Description

Technical Field

[0001] This utility model generally relates to the technical field of battery charging devices, and more specifically to a charging plug-in device for a battery pack, a charging battery compartment, and a charging and swapping station. Background Technology

[0002] Currently, most existing battery swapping stations for new energy electric vehicles use a power source to drive the plug to close the battery pack, thus achieving charging. However, using a power source-driven charging system increases costs and requires circuit control for operation.

[0003] In the existing technology, the charging devices of some battery compartments without power sources mostly use cam sliding groove mechanism, bearing sliding groove mechanism or gear rack mechanism to achieve the closing of the plug and battery pack for charging. Due to the use of rigid mechanical transmission, the overvoltage when the plug and battery pack are closed depends entirely on the floating amount of the plug itself. Insufficient adjustment amount can lead to damage to the plug and battery pack. Utility Model Content

[0059] Figures 1 to 4 A charging plug-in device 120 for a battery pack 110 according to the present invention is shown. The charging plug-in device 120 includes a fixed plate 130, a movable plate 140, an electrical plug 160, a first elastic element 170, and a transmission assembly 180.

[0060] The movable plate 140 is movably connected to the fixed plate 130 along the height direction Z of the charging plug-in device 120 between the highest and lowest positions. The mounting base 150 is movably connected to the movable plate 140 along a first horizontal direction D1 perpendicular to the height direction Z between an inserted position and a disengaged position.

[0061] A power plug 160 is disposed on a mounting base 150 for insertion into a battery pack 110 when the mounting base 150 moves to a plugging position. A first elastic element 170 is disposed between the power plug 160 and the mounting base 150 for providing elastic force to the power plug 160 along a first horizontal direction D1.

[0062] The transmission assembly 180 is disposed between the mounting base 150 and the fixed plate 130. The transmission assembly 180 is configured to convert the movement of the movable plate 140 relative to the fixed plate 130 in the height direction Z into the movement of the mounting base 150 relative to the movable plate 140 in the first horizontal direction D1.

[0063] According to the charging and plugging device 120 of the battery pack 110 of this utility model, during use, the battery pack 110 is placed on the movable plate 140. Under the gravity of the battery pack 110, the movable plate 140 moves from the highest position to the lowest position. Under the action of the transmission component 180, the mounting base 150 moves from the disengaged position to the plugged position along the first horizontal direction D1, thereby allowing the electrical plug 160 on the mounting base 150 to be plugged into the battery pack 110, thus charging the battery pack 110. There is no need for a separate power source to drive the electrical plug 160, resulting in a compact structure, stable transmission, and low failure rate. The first elastic element 170 provides elastic force when the electrical plug 160 is plugged into the battery pack 110, thereby reducing damage to the electrical plug 160 and the battery pack interface 111 when the electrical plug 160 is plugged into the battery pack 110.

[0064] Reference Figure 1 This utility model also provides a rechargeable battery compartment, including a battery rack 100 and at least two charging plug-in devices 120 according to the above-described battery pack 110. The battery rack 100 is provided with at least two receiving slots 101 arranged along the height direction Z of the battery rack 100, and the receiving slots 101 are used to accommodate batteries. At least two charging plug-in devices 120 are correspondingly arranged in the receiving slots 101 for connecting the corresponding battery packs 110 in the receiving slots 101. According to the rechargeable battery compartment of this utility model, the power plug 160 and the battery pack 110 can be plugged in by the gravity of the battery pack 110, without the need for a separate power source to drive the power plug 160. The structure is compact, the transmission is stable, the failure rate is low, and the first elastic element 170 provides elastic force when the power plug 160 is plugged into the battery pack 110, thereby reducing the damage to the power plug 160 and the battery pack interface 111 when the power plug 160 is plugged into the battery pack 110.

[0065] Reference Figure 1In some embodiments of this utility model, the battery rack 100 includes a base frame 103, two side supports 105, a top frame 104, a back frame 107, and multiple support frames 106. The base frame 103 and the top frame 104 are spaced apart along the height direction Z. The two side supports 105 are arranged at both ends of the base frame 103 along a first horizontal direction D1, and the side supports 105 are located between the base frame 103 and the top frame 104. The back frame 107 is arranged on one side of the base frame 103 along a second horizontal direction D2 perpendicular to the first horizontal direction D1. The multiple support frames 106 are connected to the two side supports 105, and the multiple support frames 106 are spaced apart along the height direction Z. The support frames 106 on the two side supports 105 are arranged one-to-one along the height direction Z, thereby forming multiple receiving slots 101 arranged sequentially along the height direction Z on the battery rack 100 for accommodating multiple battery packs 110 (or batteries and other battery modules, etc.; this embodiment only uses battery pack 110 as an example).

[0066] Optionally, the fixing plate 130 of the charging plug-in device 120 is provided with mounting holes 131 for mounting to the support frame 106 by fasteners, so as to plug in and charge the battery pack 110 placed in the receiving slot 101.

[0067] Combination Figure 2 As shown, in the charging battery compartment working chamber, the shift fork mechanism 102 transports the battery pack 110 and transfers it into the receiving slot 101 of the battery rack 100. During the process of the shift fork mechanism 102 placing the battery pack 110, the battery pack 110 abuts against the movable plate 140, causing the movable plate 140 to move from the highest position to the lowest position along the height direction Z. Under the action of the transmission component 180, the drive mounting base 150 is moved from the disengaged position to the plugged position along the first horizontal direction D1, thereby causing the electrical plug 160 on the mounting base 150 to be plugged into the battery pack 110.

[0068] Reference Figure 3 In some embodiments of this utility model, the charging plug-in device 120 further includes a guide rod 190, a guide sleeve 191, and a second elastic element 192. The guide rod 190 extends along the height direction Z and passes through the guide sleeve 191. One of the guide rod 190 and the guide sleeve 191 is disposed on the movable plate 140, and the other of the guide rod 190 and the guide sleeve 191 is disposed on the fixed plate 130. Figure 3In the illustrated embodiment, the guide rod 190 is disposed on the fixed plate 130, and the guide sleeve 191 is disposed on the movable plate 140. When the movable plate 140 moves along the height direction Z, the guide rod 190 passes through the guide sleeve 191 along the height direction Z, thereby making the movement direction of the movable plate 140 relative to the fixed plate 130 parallel to the height direction Z, thus guiding the movable plate 140. The second elastic element 192 is sleeved on the guide rod 190 and arranged between the movable plate 140 and the fixed plate 130 along the height direction Z, thereby buffering the movement of the movable plate 140, and further buffering the mounting base 150 and the electrical plug 160, reducing wear between the interface of the electrical plug 160 and the battery pack 110. In addition, the second elastic element 192 provides elastic force for the reset of the charging plug-in device 120. In detail, when the battery pack 110 is lifted away from the movable plate 140 by the shift fork mechanism 102, the movable plate 140 moves from the lowest position to the highest position under the elastic action of the second elastic element 192. Through the cooperation of the transmission assembly 180, the mounting base 150 moves from the insertion position to the disengagement position, thereby realizing the power-off action of the battery pack 110.

[0069] The guide rod 190, guide sleeve 191, and second elastic element 192 constitute a guide structure between the movable plate 140 and the fixed plate 130. In some embodiments of this utility model, combined with... Figure 4 As shown, the charging plug-in device 120 includes three guide structures. The three guide structures are arranged along a second horizontal direction D2 that is perpendicular to the first horizontal direction D1 and the height direction Z, so that the movement of the movable plate 140 on both sides along the second horizontal direction D2 is more balanced, which also helps to improve the plugging accuracy of the charging plug-in device 120.

[0070] In some embodiments of this utility model, reference is made to Figure 3 Among the three guide structures, the central guide structure is spaced apart from the other two guide structures along the first horizontal direction D1, which makes the movement of the movable plate 140 on both sides along the first horizontal direction D1 more balanced, and further helps to improve the plugging accuracy of the charging plugging device 120.

[0071] In some embodiments of this utility model, reference is made to Figure 1 and Figure 3 A support block 141 is provided on the side of the movable plate 140 near the battery pack 110. The support block 141 is used to engage with the bottom of the battery pack 110, so that during the placement of the battery pack 110, the support block 141 can transfer the weight of the battery pack 110 to the movable plate 140, causing the movable plate 140 to move along the height direction Z. The top of the support block 141 can be constructed of a flexible material, such as rubber, thereby reducing wear on the bottom of the battery pack 110.

[0072] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 The charging plug-in / plug-out device 120 also includes a slide rail 193 and a slider 194. The slide rail 193 is fixed to the movable plate 140 and extends along a first horizontal direction D1. The slider 194 is movably connected to the slide rail 193 along the first horizontal direction D1, and the bottom surface of the mounting base 150 is connected to the slider 194. Through the cooperation of the slide rail 193 and the slider 194, the mounting base 150 is movably connected to the movable plate 140 along the first horizontal direction D1 between an inserted position and a disengaged position, which guides the movement of the mounting base 150 relative to the movable plate 140, making the movement of the mounting base 150 more stable. In addition, the cooperation of the slide rail 193 and the slider 194 also limits the distance between the mounting base 150 and the movable plate 140 along the height direction Z, so that the transmission assembly 180 can convert the movement of the movable plate 140 relative to the fixed plate 130 along the height direction Z into the movement of the mounting base 150 relative to the movable plate 140 along the first horizontal direction D1.

[0073] In some embodiments of this utility model, reference is made to Figure 3 The movable plate 140 is provided with a through groove 142. The transmission component 180 passes through the through groove 142 and is connected to the mounting base 150 and the fixed plate 130 respectively, so that the transmission component 180 can be connected to the fixed plate 130 and the mounting base 150 respectively, thereby allowing the movement of the movable plate 140 to be transmitted to the mounting base 150.

[0074] In some embodiments of this utility model, reference is made to Figure 3 The projection of the transmission component 180 along the height direction Z falls within the projection range of the through slot 142 along the height direction Z, so that the arrangement of the transmission component 180 does not affect the travel of the movable plate 140 relative to the fixed plate 130, thereby allowing the mounting base 150 to have sufficient travel to be inserted and fitted into the battery pack 110.

[0075] In some embodiments of this utility model, reference is made to Figure 3The transmission assembly 180 includes a first transmission plate 181, a second transmission plate 182, and a cam 183. The first transmission plate 181 is connected to the fixed plate 130 by fasteners. The second transmission plate 182 is connected to the mounting base 150 by fasteners. A guide groove 184 is provided on the side wall of the second transmission plate 182, and the cam 183 is disposed on the first transmission plate 181 and engages with the guide groove 184. The guide groove 184 is set at an angle to the first horizontal direction D1, and the bottom end of the guide groove 184 is close to the insertion position, while the top end of the guide groove 184 is close to the disengagement position. When the movable plate 140 moves along the height direction Z, the mounting base 150 moves along the height direction Z along with the movable plate 140 through the cooperation of the slider 194 and the slide rail 193. This causes the second transmission plate 182 to move along the height direction Z. With the cooperation of the cam 183 and the guide groove 184, the second transmission plate 182 and the mounting base 150 move along the first horizontal direction D1, thereby allowing the electrical plug 160 on the mounting base 150 to move along the first horizontal direction D1. Specifically, when the cam 183 is at the top of the guide groove 184, the movable plate 140 is at its highest position, and the mounting base 150 is in the disengaged position; when the cam 183 is at the bottom of the guide groove 184, the movable plate 140 is at its lowest position, and the mounting base 150 is in the insertion position.

[0076] Under the action of transmission component 180:

[0077] When the movable plate 140 moves from the highest position to the lowest position along the height direction Z, the mounting base 150 moves from the disengaged position to the plugged position relative to the movable plate 140 along the first horizontal direction D1, thereby driving the power plug 160 on the mounting base 150 so that the power plug 160 is plugged into the battery pack 110.

[0078] When the battery pack 110 is lifted, under the elastic force of the second elastic element 192, the movable plate 140 moves from the lowest position to the highest position along the height direction Z, and the mounting base 150 moves from the plugged position to the disengaged position relative to the movable plate 140 along the first horizontal direction D1, thereby driving the power plug 160 on the mounting base 150 so that the power plug 160 disengages from the battery pack 110.

[0079] The transmission assembly 180 effectively converts the movement of the movable plate 140 along the height direction Z into the movement of the mounting base 150 along the first horizontal direction D1, resulting in high transmission efficiency. Furthermore, the axial dimension (the dimension along the second horizontal direction D2) is small and the structure is compact due to the cooperation of the cam 183 and the guide groove 184. With the cooperation of the through groove 142, the movement stroke of the movable plate 140 along the height direction Z will not be affected.

[0080] In some embodiments of this utility model, reference is made to Figure 3The charging plug-in / plugging device 120 includes two transmission components 180, which are arranged at intervals along the second horizontal direction D2 and on both sides of the slide rail 193. Correspondingly, the movable plate 140 is provided with two through slots 142, which are arranged one-to-one with the transmission components 180. The arrangement of the transmission components 180 makes the movement of the two sides of the mounting base 150 more balanced, thereby making the plugging and unplugging control of the charging plug-in / plugging device 120 more precise.

[0081] In some embodiments of this utility model, reference is made to Figure 3 The through groove 142 extends along the first horizontal direction D1, so that the movable plate 140 can fully avoid the transmission assembly 180 (e.g., the first transmission plate 181 and the second transmission plate 182) during the movement, so that the transmission assembly 180 can smoothly and effectively convert the movement of the movable plate 140 along the height direction Z into the movement of the mounting base 150 along the first horizontal direction D1.

[0082] In some embodiments of this utility model, reference is made to Figure 3 The mounting base 150 has an L-shaped cross-section perpendicular to the second horizontal direction D2, and a reinforcing rib 152 is provided on the back of the mounting base 150 away from the battery pack 110, thereby enhancing the structural strength of the mounting base 150. A clearance groove 151 is also provided on the side wall of the mounting base 150 perpendicular to the first horizontal direction D1, to prevent the wiring harness of the connecting plug 160 from affecting the relative movement between the plug 160 and the mounting base 150.

[0083] In some embodiments of this utility model, reference is made to Figure 3 The first elastic element 170 includes a limiting bolt 172 and a telescopic spring 171. The limiting bolt 172 passes through the side wall of the plug 160 and the mounting base 150 perpendicular to the first horizontal direction D1. A nut is fitted at the end of the limiting bolt 172, and the nut is threadedly connected to the limiting bolt 172. This allows the plug 160 and the mounting base 150 to move within a certain range of travel, preventing a rigid connection between the mounting base 150 and the plug 160 and preventing the plug 160 from detaching from the mounting base 150. The telescopic spring 171 is fitted onto the limiting bolt 172 and is arranged along the first horizontal direction D1 between the mounting base 150 and the plug 160, thereby providing an elastic connection between the plug 160 and the mounting base 150 and reducing wear when the plug 160 is inserted into the battery pack interface 111. Optionally, the charging plug-in device 120 includes four first elastic elements 170, which are arranged at the four corners of the plug 160, thereby making the relative movement between the plug 160 and the mounting base 150 more balanced and stable.

[0084] This utility model also provides a charging and battery swapping station, including the charging battery compartment as described above. According to this utility model, the charging and battery swapping station can utilize the gravity of the battery pack 110 to connect the plug 160 and the battery pack 110, eliminating the need for a separate power source to drive the plug 160. It features a compact structure, stable transmission, low failure rate, and reduces damage to the plug 160 and the battery pack interface 111 when the plug 160 is connected to the battery pack 110.
