Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

The invention provides a charging rack 100 for a battery pack transfer device to place a battery pack 30 for use, wherein the charging rack 100 comprises a bearing mechanism 1 and an electric connection mechanism 2. The carrying mechanism 1 carries the battery pack 30 through a carrying frame, as shown in fig. 1 and fig. 2, the carrying mechanism 1 has a frameless space 1a for an extending mechanism (not shown) of the battery pack transfer device to enter when the battery pack transfer device places the battery pack 30 on the carrying mechanism 1, and the electrical connection mechanism 2 is disposed on the carrying mechanism 1, and the electrical connection mechanism 2 is used for electrically connecting with the battery pack 30 after the battery pack 30 is placed on the carrying mechanism 1, so as to charge the battery pack 30.

Specifically, the protruding mechanism of the battery pack transfer device is usually a plug board disposed on the lower surface of the battery pack 30, and after such protruding mechanism transports and places the battery pack 30 downward on the carrying mechanism 1, the protruding mechanism can further move downward to be quickly withdrawn from the charging rack 100 without interfering with other parts of the charging rack 100. Therefore, the charging bin 10 can avoid the interference of the battery pack transfer device with the support mechanism 1 when the battery pack 30 is placed or taken out relative to the support mechanism 1 by arranging the frameless space 1a for the extension mechanism of the battery pack transfer device to enter on the support mechanism 1, and can simplify the structure of the charging bin 10. On the other hand, the charging cabin 10 can save the space reserved for avoiding the extension mechanism of the battery pack transfer device to extend and retract under the battery pack by arranging the frameless space 1a for the extension mechanism of the battery pack transfer device to enter on the bearing mechanism 1, so that the space occupied by the charging cabin is reduced in height.

That is to say, the extending mechanism of the battery pack transferring device only needs to move downwards continuously to continuously realize the two steps of placing the battery pack 30 on the carrying frame and withdrawing from the charging frame 100, and in contrast, the extending mechanism of the battery pack transferring device only needs to move upwards continuously to continuously realize the two steps of entering the charging bin 10 and taking out the battery pack 30 from the carrying frame, so that the flow steps of taking and placing the battery pack 30 can be effectively simplified.

Taking this embodiment as an example, the carrying frame of the carrying mechanism 1 may specifically include a front carrying frame 111 and a rear carrying frame 112, and the front carrying frame 111 and the rear carrying frame 112 are distributed at two ends of the battery pack 30 to carry the battery pack 30 together. The frameless space 1a is formed in a gap formed between the front carrying frame 111 and the rear carrying frame 112, and the electrical connection mechanism 2 is disposed on the front carrying frame 111, so that the frameless space 1a is formed on the carrying mechanism 1 by separately disposing frames.

As shown in fig. 2 to 4, first aligning mechanisms 16 are respectively disposed on the left and right sides of the front carrier frame 111, and second aligning mechanisms 301 are disposed at positions on the side surfaces of the battery pack 30 corresponding to the first aligning mechanisms 16. When the battery pack 30 is placed on the bearing mechanism 1 by the battery pack transfer device from top to bottom, the first aligning mechanism 16 is matched with the second aligning mechanism 301 on the battery pack 30, so that the purpose of positioning and placing the battery pack 30 on the bearing mechanism 1 is achieved.

In this embodiment, as shown in fig. 3, the first aligning mechanism 16 is a guide fork, the second aligning mechanism 301 is an aligning block, and the aligning block is configured to be fittingly positioned in the slot 162 between the two fork portions 161 of the guide fork, so as to limit the horizontal displacement of the second aligning mechanism 301 through the two fork portions 161, and achieve the purpose of positioning the battery pack 30 relative to the bearing mechanism 1. Among them, as for the fork part 161 of the guide fork, the top thereof may preferably have an inclined surface or an arc surface arranged toward the inner direction of the guide fork, so as to form a guide structure by using the above inclined surface or arc surface, and the position of the battery pack 30 is guided by the way that the inner side surface of the fork part 161 contacts with the side surface of the battery pack 30, which may effectively improve the position accuracy and reliability of placing the battery pack 30. In addition, the top of the fork 161 of the guide fork can be turned outwards towards the outside of the charging bin 10, so as to form a guide structure for the battery pack 30 on the inside of the fork 161, thereby realizing the alignment adjustability of the battery pack 30 in the width direction and accurately positioning and placing the battery pack on the bearing frame.

As shown in fig. 2, the carrying mechanism 1 further includes a third aligning mechanism 17, the third aligning mechanism 17 is respectively disposed on the left and right sides of the rear carrying frame 112, the third aligning mechanism 17 is also used for positioning the battery pack 30, so that when the battery pack 30 is placed on the carrying mechanism 1 from top to bottom in the battery pack transferring device, the positioning of the battery pack 30 by the carrying mechanism 1 is increased from two guiding aligning points to a guiding aligning surface having four guiding aligning points through the guiding aligning function of the third aligning mechanism 17, thereby increasing the aligning accuracy and the success rate for placing the battery pack 30. In the present embodiment, the third aligning mechanism 17 is a vertically arranged sheet structure, and the top of the third aligning mechanism 17 is turned outwards towards the outside of the charging bin 10, so as to form a guiding structure for the battery pack 30 inside the top end of the third aligning mechanism 17.

In addition, the front and rear carrying frames 111 and 112 are provided with a reinforcing beam 113 at a position far from the entering side of the protruding mechanism of the battery pack transfer device, that is, the reinforcing beam 113 is disposed at the rear side of the charging bin 10, two ends of the reinforcing beam 113 are respectively connected to the front and rear carrying frames 111 and 112, so as to simultaneously reinforce the front and rear carrying frames 111 and 112, compensate for the reduction of the frame strength caused by the split frame structure, and meanwhile, the position of the reinforcing beam 113 avoids occupying the middle frameless space 1 a. In other embodiments, the reinforcing beam 113 may also be directly integrated with the front or

rear carrier frame

111, 112 to improve the fixing effect.

By directly arranging the electrical connection mechanism 2 on the first bearing table 12 for placing the battery pack 30, the accuracy of the relative position between the electrical connection mechanism 2 and the battery pack 30 when the battery pack 30 is placed on the first bearing table 12 can be ensured, so that the reliability and accuracy of the butt joint of the electrical connection mechanism 2 and the battery pack 30 are improved. In the present embodiment, the first stage 12 is disposed above the front carrier frame 111.

In addition, a push-pull mechanism for driving the electrical connection mechanism 2 to be inserted into the battery pack 30 is further provided on the first carrier 12. After the battery pack 30 is placed on the first bearing table 12, the push-pull mechanism drives the electrical connection mechanism 2 to be electrically connected with the electrical connector on the battery pack 30; when the battery pack 30 is lifted up relative to the first bearing table 12, the push-pull mechanism drives the electric connector to be separated from the electric connector on the battery pack 30, so that the purpose of plugging and unplugging the electric connector relative to the battery pack 30 is achieved by arranging the push-pull mechanism.

Wherein, the upper surface of the first bearing platform 12 may further be provided with a buffer pad 121, and the buffer pad 121 is used to directly contact with the battery pack 30, so as to reduce the impact generated when the battery pack 30 is placed on the first bearing platform 12. Preferably, the surface of the buffer pad 121 contacting the battery pack 30 may be a smooth surface to avoid a horizontal friction force between the buffer pad 121 and the battery pack 30.

The push-pull mechanism may be a horizontal electric push-pull mechanism to drive the electric connector to horizontally reciprocate by inputting electric power to a horizontal driver connected to the electric connector, thereby realizing plugging and unplugging with respect to the battery pack 30. In this embodiment, the push-pull mechanism is an obliquely guiding push-pull mechanism, and the obliquely guiding push-pull mechanism includes a mounting seat 131, the mounting seat 131 is formed on the outer surface of the housing of the electrical connection mechanism 2, the mounting seat 131 is connected to the first bearing platform 12 through a sliding rail device 132 to achieve a relative horizontal movement with the first bearing platform 12, and is connected to the front bearing frame 111 through an orientation device 133 to achieve a relative oblique movement with the front bearing frame 111. The slide rail device 132 and the orientation device 133 cooperate with each other to enable the electrical connection mechanism 2 to move back and forth, so that after the battery pack 30 is placed on the first carrier 12, the gravity applied by the battery pack 30 to the first carrier 12 is used as a driving force to achieve the purpose of electrically connecting or disconnecting the electrical connection mechanism 2 with the electrical connector on the battery pack 30.

Specifically, as shown in fig. 6-8, the slide rail device 132 includes vertical plates 1321 disposed on both sides of the first carrier 12, and pulleys 1322 disposed on both side surfaces of the mounting seat 131, and a sliding slot 1323 extending in the horizontal direction and engaged with the pulley 1322 is disposed on the vertical plate 1321 at a position corresponding to the pulley 1322, so that the mounting seat 131 can move in the horizontal direction relative to the first carrier 12 through the sliding slot 1323 after being mounted on the first carrier 12. Of course, the structure of the slide rail device 132 is not limited to this, and in other embodiments, a slide rail may be disposed at a position corresponding to the pulley 1322, so as to cooperate with the slide slot 1323 on the vertical plate 1321 through the slide rail, and achieve the purpose of moving in the horizontal direction.

The present embodiment also provides a preferred implementation for the orientation device 133. As shown in fig. 5 and 9, the orientation device 133 may include a guide plate 1331 mounted on the mounting base 131 and having an inclined groove 1331a, and a horizontally disposed limiting rod 1332 mounted on the front carrying frame 111, wherein the inclined groove 1331a is inclined downward along the direction of approaching the battery pack 30 by the electrical connection mechanism 2, and the limiting rod 1332 passes through the inclined groove 1331a, so that the mounting base 131 is driven to move downward along the extending direction of the inclined groove 1331a by the gravity of the battery pack 30 when a battery is placed on the first carrying platform 12, so as to drive the electrical connection mechanism 2 to move toward the battery pack 30, thereby achieving the purpose of electrically connecting the electrical connection device on the battery pack 30. And when the battery pack 30 is lifted up on the first bearing table 12, the battery pack 30 moves upward, so that the mounting seat 131 moves in the opposite direction to drive the electrical connection mechanism 2 to move in the direction away from the battery pack 30, thereby achieving the purpose of separating the battery pack 30 from the electrical connector. As shown in fig. 6, an opening 122 is provided on the surface of the first platform 12, and the opening 122 is used for allowing the mounting seat 131 located above to lift the guide plate 1331 thereof downward so as to engage with the limiting rod 1332 fixed on the front bearing frame 111 through the inclined groove 1331a thereof for shaft hole matching.

Of course, if the number of the elastic devices 14 is more than three, the supporting capability of the first carrier stage 12 will be correspondingly improved.

The supporting mechanism 1 further comprises a guiding device 15, wherein the guiding device 15 is used for guiding the elastic device 14 to move elastically along the vertical direction so as to ensure that the first supporting platform 12 moves vertically relative to the front supporting frame 111, so that the front supporting frame 111 supports the first supporting platform 12 elastically along the vertical direction.

Meanwhile, the elastic device 14 in this embodiment is a compression spring, which is sleeved on the guide rod 151 and located between the guide hole 152 and the first bearing platform 12, so as to utilize the resilience generated when the compression spring is compressed to drive the first bearing platform 12 to reset upwards when the battery pack 30 is separated from the first bearing platform 12.
