Description

Technical Field

[0001] This application belongs to the field of battery charging equipment technology, specifically relating to a battery charging carrier. Background Technology

[0002] Currently, the requirements for battery storage include: the storage location must be clean, ventilated and dry; protective measures such as dust prevention, moisture prevention and impact prevention must be taken for the batteries (e.g., using a tray to store the batteries); batteries stored for more than six months should be recharged; and used batteries should be fully charged before storage.

[0003] However, batteries may experience abnormal phenomena such as power loss during long-term storage. This is especially true for used batteries. If a battery is depleted due to power loss during storage and is not recharged in time, it may be damaged after being left for a long time. Utility Model Content

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0017] The battery charging carrier provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0018] like Figures 1 to 10 As shown in the figure, this application provides a battery charging carrier, which includes a charging base 100 and a power connector 200.

[0019] The charging dock 100 includes a base 110 and a circuit board 120. The base 110 has a battery compartment 111 for accommodating a battery 300. The battery 300 can be a new battery or a used battery; this embodiment does not impose specific limitations on this. The circuit board 120 is disposed on the base 110 and has a charging interface 121 located on the circuit board 120 near the battery compartment 111. The charging interface 121 is used to electrically connect to the connector 310 of the battery 300.

[0020] A power connector 200 is disposed on the charging base 100 and is electrically connected to the circuit board 120. The power connector 200 is used to electrically connect to an external power source, thereby transmitting current from the external power source to the charging base 100. When the battery 300 is placed in the battery compartment 111, the connector 310 of the battery 300 is inserted and engaged with the charging interface 121 on the circuit board 120, and the power connector 200 transmits current from the external power source to the circuit board 120, thereby charging the battery 300.

[0021] The battery charging carrier provided in this application embodiment allows the battery 300 to be electrically connected to the charging interface 121 on the circuit board 120 of the charging carrier 100 when the battery 300 is placed in the battery compartment 111. This enables the battery 300 to be charged, preventing damage to the battery 300 due to lack of timely charging after power loss during storage. Therefore, this application embodiment can solve the current problem of battery 300 being damaged due to lack of timely charging after power loss during storage.

[0022] In addition, the battery charging carrier provided in the above embodiments can avoid the need to charge batteries separately after they have lost power during battery storage, which helps to improve the efficiency of battery maintenance and management.

[0023] In one optional embodiment, the base 110 is provided with a receiving groove 112, and the circuit board 120 is disposed in the receiving groove 112, thereby avoiding the circuit board 120 occupying additional space in the thickness direction of the base 110. Of course, the receiving groove 112 may not be provided, in which case the circuit board 120 is stacked on the top surface of the base 110.

[0024] Optionally, the number of charging bases 100 can be one, or the number of charging bases 100 can be at least two, with each charging base 100 stacked sequentially. The at least two charging bases 100 include a main charging base 130 and a secondary charging base 140. The secondary charging base 140 is disposed above the main charging base 130. A power connector 200 is disposed on the main charging base 130 and is electrically connected to the circuit board 120 of the main charging base 130. The secondary charging base 140 is provided with an interlayer connector 141, which is electrically connected to the circuit board 120 of the secondary charging base 140. Optionally, the interlayer connector 141 is electrically connected to the conductive part 124 on the circuit board 120, and the interlayer connector 141 can also be electrically connected to the circuit board 120 of the main charging base 130. When it is necessary to charge the battery 300 stored on the charging sub-base 140, the interlayer connector 141 provided on the charging sub-base 140 is electrically connected to the circuit board 120 of the charging main base 130, so that the current on the charging main base 130 is transmitted to the charging sub-base 140, thereby energizing the charging sub-base 140 and charging the battery 300 stored on it. This solution increases the number of batteries 300 that can be stored by setting up multiple charging bases 100, thereby improving the utilization rate of the battery charging carrier; in addition, when the charging bases 100 are stacked in sequence, the circuit board 120 of each charging base 100 is set in the receiving slot 112 of the base 110, which can reduce the space occupied by each charging base 100 in the vertical direction, thereby reducing the height of the battery charging carrier.

[0025] In a further optional embodiment, the side of the charging main seat 130 facing the charging auxiliary seat 140 is a first surface 131, and the side of the charging auxiliary seat 140 facing the charging main seat 130 is a second surface 142. In the direction extending from the battery compartment 111 to the receiving groove 112, one of the first ends of the first surface 131 and the first ends of the second surface 142 is provided with a first positive magnetic element 132 (i.e., the magnetic line emitted by the magnetic element points to the end near the geographic North Pole), and the other is provided with a first negative magnetic element 143 (i.e., the magnetic line emitted by the magnetic element points to the end near the geographic South Pole). The first positive magnetic element 132 and the first negative magnetic element 143 are magnetically connected, so that the first end of the charging main seat 130 and the first end of the charging auxiliary seat 140 are detachably connected. The second end of the first surface 131 and the second end of the second surface 142 are each provided with a second positive magnetic element 133 (i.e., the magnetic lines emitted by this magnetic element point towards the geographic North Pole) or a second negative magnetic element (i.e., the magnetic lines emitted by this magnetic element point towards the geographic South Pole). That is, the second ends of the first surface 131 and the second ends of the second surface 142 are both provided with magnetic elements of the same polarity, which repel each other. Optionally, at least one of the first positive magnetic element 132, the first negative magnetic element 143, the second positive magnetic element 133, and the second negative magnetic element can be a magnet.

[0026] The battery charging carrier also includes a positioning buckle 400, one end of which is rotatably connected to the second end of the main charging seat 130. Optionally, the positioning buckle 400 and the main charging seat 130 can be rotatably connected via a connecting shaft. The positioning buckle 400 is provided with a positioning groove 410, and the second end of the auxiliary charging seat 140 is provided with a positioning protrusion 144. When the positioning protrusion 144 and the positioning groove 410 are engaged, the interlayer connector 141 is electrically connected to the circuit board 120 of the main charging seat 130. When the positioning protrusion 144 and the positioning groove 410 are disengaged, the like magnetic forces between the second end of the main charging seat 130 and the second end of the auxiliary charging seat 140 repel each other, thereby disconnecting the interlayer connector 141 from the circuit board 120 of the main charging seat 130.

[0027] Specifically, when the battery 300 stored on the charging sub-base 140 needs charging, the positioning buckle 400 is rotated so that the positioning groove 410 on the positioning buckle 400 is positioned and engaged with the positioning protrusion 144 of the charging sub-base 140. At this time, the force between the positioning buckle 400 and the charging sub-base 140 can counteract the magnetic repulsion between the second end of the charging main base 130 and the second end of the charging sub-base 140, so that the interlayer connector 141 of the charging sub-base 140 is electrically connected to the circuit board 120 of the charging main base 130, thereby charging the battery 300 stored on the charging sub-base 140. 00 Charging begins; once the battery 300 stored on the charging sub-base 140 has finished charging, the positioning groove 410 of the positioning buckle 400 can be disengaged from the positioning protrusion 144 of the charging sub-base 140. At this time, due to magnetic repulsion, the second end of the charging sub-base 140 is lifted up. The interlayer connector 141 of the charging sub-base 140 is disconnected from the circuit board 120 of the charging main base 130, thereby preventing the charging sub-base 140 from continuing to consume power and thus saving power consumption of the battery charging carrier.

[0028] Optionally, in the direction from the end of the positioning buckle 400 connected to the charging main seat 130 to the end away from the charging main seat 130, the width of the positioning groove 410 can be equal; or, in other optional embodiments, in the direction from the end of the positioning buckle 400 connected to the charging main seat 130 to the end away from the charging main seat 130, the positioning groove 410 has a first positioning plane 411 and a first guide slope 412 disposed opposite to each other. The first guide slope 412 is located between the first positioning plane 411 and the rotation center axis of the positioning buckle 400. In the direction from the opening of the positioning groove 410 to the bottom of the groove, the distance between the first positioning plane 411 and the first guide slope 412 gradually decreases, that is, the positioning groove 410 has a V-shaped structure. Correspondingly, the positioning protrusion 144 has a second positioning plane 144a and a second guide slope 144b arranged opposite to each other. The second guide slope 144b is connected to the second positioning plane 144a. The first guide slope 412 can guide and cooperate with the second guide slope 144b. The first positioning plane 411 can position and cooperate with the second positioning plane 144a in the thickness direction of the base 110.

[0029] During the rotation of the positioning buckle 400, the first guide slope 412 and the second guide slope 144b guide and cooperate to ensure that the positioning groove 410 and the positioning protrusion 144 of the positioning buckle 400 are smoothly positioned and engaged or disengaged, thereby improving the work efficiency of the staff in maintaining the battery. When the positioning groove 410 and the positioning protrusion 144 of the positioning buckle 400 are positioned and engaged, the first positioning plane 411 and the second positioning plane 144a are positioned and engaged in the thickness direction of the base 110, thereby improving the positioning stability between the positioning buckle 400 and the charging sub-base 140, and further improving the stability of current transmission between the interlayer connector 141 of the charging sub-base 140 and the charging main base 130.

[0030] Optionally, there are at least two positioning grooves 410, with each positioning groove 410 spaced apart along the length of the positioning buckle 400. The charging sub-base 140 corresponds one-to-one with each positioning groove 410, allowing the battery charging carrier to hold a larger number of batteries 300. It should be noted that when there are multiple charging sub-bases 140, there is a preset distance between adjacent charging sub-bases 140 to ensure sufficient heat dissipation for the batteries 300 stored on each charging sub-base 140. Optionally, there can be four charging sub-bases 140, which avoids making the overall height of the battery charging carrier excessively large.

[0031] In another optional embodiment, the main charging base 130 is provided with a positioning post 134. Optionally, the positioning post 134 is located on the side of the receiving groove 112 opposite to the battery compartment 111. The auxiliary charging base 140 is provided with a positioning hole 145. The auxiliary charging base 140 is fitted onto the positioning post 134 through the positioning hole 145, so that the auxiliary charging base 140 and the main charging base 130 are positioned and engaged, thereby preventing the auxiliary charging base 140 from shifting relative to the main charging base 130 when the positioning protrusion 144 and the positioning groove 410 are disengaged. Furthermore, during the installation of the auxiliary charging base 140 onto the main charging base 130, the positioning post 134 can act as a guide, thereby improving the installation efficiency of the auxiliary charging base 140. Of course, the positioning post 134 can also be omitted.

[0032] And / or, one of the opposing sides of the main charging seat 130 and the auxiliary charging seat 140 is provided with a limiting groove 135, and the other is provided with a limiting post 146. The limiting post 146 and the limiting groove 135 are matched in the radial direction of the limiting post 146 (i.e., in the direction perpendicular to the depth direction of the battery compartment 111) to prevent the auxiliary charging seat 140 from tilting or shifting relative to the main charging seat 130 when the positioning protrusion 144 and the positioning groove 410 are matched.

[0033] Optionally, the charging main seat 130 is provided with the aforementioned limiting groove 135 on the side facing the charging auxiliary seat 140. The number of limiting grooves 135 is at least two, and each limiting groove 135 is provided on the edge of the charging main seat 130. The limiting grooves 135 are arranged at intervals along the circumference of the charging main seat 130. The limiting post 146 is provided in a one-to-one correspondence with the limiting groove 135, thereby improving the relative stability between the charging auxiliary seat 140 and the charging main seat 130 when the positioning protrusion 144 and the positioning groove 410 are in positioning cooperation.

[0034] In another optional embodiment, each charging base 100 has a handle groove 113 on its base 110. The handle groove 113 and the battery compartment 111 are both located on the top surface of the base 110, and the handle groove 113 extends to the circumference of the base 110. During the handling or installation of each charging base 100, the hand can grip the handle groove 113, thereby improving the work efficiency of the operator. Optionally, the handle groove 113 and the battery compartment 111 can be spaced apart, or the handle groove 113 can be connected to the battery compartment 111. During the process of placing the battery 300 into the battery compartment 111 or removing the battery 300 from the battery compartment 111, the hand can be placed in the handle groove 113 to facilitate the operator's placement and removal of the battery 300. Hand grooves 113 are provided on both opposite sides of the battery compartment 111 to facilitate the operator's two-handed handling of the charging base 100, especially for heavier charging bases 100. In another optional embodiment, the number of charging ports 121 is at least two, and the battery compartment 111 is provided with at least one partition strip 150 to divide the battery compartment 111 into at least two storage compartments arranged at intervals. Each storage compartment is arranged in a one-to-one correspondence with each charging port 121. That is to say, a charging stand 100 can store at least two batteries 300 to increase the number of batteries 300 that the charging stand 100 can store, thereby improving the utilization rate of the charging stand 100.

[0035] Optionally, the divider 150 can be fixed to the bottom of the battery compartment 111, that is, the divider 150 and the base 110 can be fixedly connected by welding, bonding or other methods; or, in other optional embodiments, the divider 150 and the base 110 are magnetically connected, in which case the divider 150 can be moved inside the battery compartment 111. When it is necessary to store batteries 300 of different sizes, the size of the compartment can be adjusted by moving the divider 150, thereby improving the adaptability of the compartment and expanding the applicability of the charging stand 100.

[0036] In an optional embodiment, the circuit board 120 includes a rigid circuit board 122 and a flexible circuit board 123. The flexible circuit board 123 is detachably disposed on the rigid circuit board 122. The charging interface 121 is disposed on the flexible circuit board 123. The flexible circuit board 123 is provided with a connector connector 123a, and the rigid circuit board 122 is provided with a connector interface 122a. The connector connector 123a and the connector interface 122a are plugged into each other to electrically connect the flexible circuit board 123 and the rigid circuit board 122. Since different types of batteries 300 correspond to different charging interfaces 121, when storing different types of batteries 300 in the battery charging carrier, the flexible circuit board 123 corresponding to the battery 300 can be replaced according to actual needs, so that the battery charging carrier can store multiple types of batteries 300. Therefore, the circuit board 120 described above can expand the applicability of the battery charging carrier. Of course, the flexible circuit board 123 described above can also be omitted, and the charging interface 121 can be directly disposed on the rigid circuit board 122. In an optional embodiment, the battery charging carrier further includes a first indicator light 160 and a second indicator light 170. Both the first and second indicator lights 160 and 170 are mounted on the circuit board 120 and electrically connected to it. The first indicator light 160 indicates the charging status of the battery 300, and the second indicator light 170 indicates the working status of the charging base 100. When the battery 300 stored on the base 110 is fully charged, the first indicator light 160 illuminates to remind the operator to disconnect the power. When the charging base 100 malfunctions during operation, the second indicator light 170 illuminates to remind the operator to promptly repair the charging base 100, thereby improving the efficiency of battery maintenance and the safety of the battery charging carrier. Alternatively, the first and second indicator lights 160 can be omitted. In this case, the operator can manually check the charging status of the battery 300 and the working status of the charging base 100.

[0037] Optionally, the first signal light 160 and the second signal light 170 can be signal lights of the same color or signal lights of different colors. For example, the first signal light 160 can be green and the second signal light 170 can be red. This application embodiment does not impose specific limitations on this.

[0038] The specific assembly process of the battery charging carrier provided in this application embodiment is as follows: First, place the battery 300 in the battery compartment 111, and then fasten the connector 310 of the battery 300 to the charging interface 121 on the flexible circuit board 123 (this is the same for placing and installing the batteries 300 stored on the main charging base 130 and the auxiliary charging base 140). Then, stack the auxiliary charging base 140 on top of the main charging base 130, and align the limiting post 146 on the back (i.e., the second side 142) of the auxiliary charging base 140 with the limiting groove 13 on the front (i.e., the first side 131) of the main charging base 130. 5. Perform alignment and fastening, simultaneously fitting the positioning holes 145 on the charging auxiliary seat 140 onto the positioning posts 134 on the charging main seat 130, and stacking 4 layers of charging auxiliary seats 140 in sequence (the number of layers of charging auxiliary seats 140 is limited by the height of the positioning buckle 400: the number of positioning grooves 410 on the positioning buckle 400 should be greater than or equal to the number of layers of charging auxiliary seats 140). At this time, since the first end of the front (i.e., the top surface) of the charging main seat 130 is provided with a first negative magnetic element 143 and the second end is provided with a second positive magnetic element 143, the charging main seat 130 will be engaged. The charging auxiliary seat 140 has a positive magnetic component 133 on its front side (i.e., bottom surface). Both the first and second ends of the back side (bottom surface) of the charging auxiliary seat 140 are provided with positive magnetic components. When the charging auxiliary seat 140 is stacked on top of the front side of the charging main seat 130, the second positive magnetic component 133 on the front side of the charging main seat 130 repels the second positive magnetic component 133 on the back side of the charging auxiliary seat 140, while the first negative magnetic component 143 on the front side of the charging main seat 130 attracts the second positive magnetic component on the back side of the charging auxiliary seat 140. At this time, the second negative magnetic component 143 on the front side of the charging main seat 130... When the first end is lifted, it attaches to the main charging base 130, causing the interlayer connector 141 to be unable to contact the circuit board 120 of the main charging base 130 and thus unable to transmit current to the secondary charging base 140. When the positioning buckle 400 is positioned and engaged with the positioning protrusion 144 of the secondary charging base 140, the positioning buckle 400 cancels the magnetic repulsion force, causing the positioning groove 410 to be positioned and engaged with the positioning protrusion 144, pressing the secondary charging base 140 into place, and electrically connecting the interlayer connector 141 and the circuit board 120 of the main charging base 130.

[0039] When using the battery charging carrier disclosed in this application, an external power source is first connected from the power connector 200. The current is transmitted through the interlayer connector 141 to the charging sub-bases 140 of different layers. Each charging sub-base 140 transmits the current to the battery 300 through the connector 310 between the flexible circuit board 123 and the battery 300, thereby enabling the simultaneous charging of batteries 300 of different layers. Meanwhile, each charging dock 140 is equipped with a first indicator light 160 and a second indicator light 170. When the battery 300 stored on the charging dock 100 of this layer is fully charged, the first indicator light 160 lights up. When the charging dock 100 of this layer malfunctions, the second indicator light 170 lights up, providing users with an intuitive status display. Conversely, when disassembling the charging dock 140, the positioning buckle 400 must be opened first. At this time, the charging dock 140 will be lifted up by magnetic repulsion due to the loss of restraint. When the charging dock 140 is lifted up, in order to prevent the charging dock 140 from tilting left and right, the limiting post 146 and the limiting groove 135 are engaged to limit it. Then, the user can immediately insert his finger into the handle groove 113 to remove the charging dock 140.

[0040] In addition, when storing batteries 300 of other sizes and models, the magnetic separator 150 can be removed or its position adjusted to change the size of the battery compartment 111 to accommodate batteries 300 of different sizes. At the same time, only the flexible circuit board 123 corresponding to the new battery 300 needs to be replaced, and other components can remain unchanged.

[0041] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
