An energy storage base and a shared energy storage device

Abstract

This utility model belongs to the field of energy storage technology and discloses an energy storage base and a shared energy storage device. The energy storage base includes a shell, a fixing head, and a snap-fit ​​component. The shell has a cable passage hole. The fixing head is fitted onto the lead wire, and the fixing head and the cable passage hole are engaged by an anti-rotation structure to prevent the fixing head from rotating relative to the cable passage hole. The snap-fit ​​component is snapped into the fixing head and abuts against the inner sidewall of the shell to restrict the axial movement of the fixing head along the cable passage hole. Because the fixing head and the cable passage hole are engaged by an anti-rotation structure to prevent the fixing head from rotating circumferentially around the cable passage hole, and because the snap-fit ​​component is snapped into the fixing head to prevent the axial movement of the fixing head relative to the cable passage hole, the stability of the fixing head is ensured, thereby ensuring the stability of the lead wire. In addition, because all the cable passage holes are located on the shell, compared with the semi-hole structure of the prior art, the edge strength of the shell is better and less prone to damage.

Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to an energy storage base and a shared energy storage device. Background Technology

[0002] The shared energy storage device consists of multiple energy storage power sources and a charging base. One charging base can charge multiple power banks simultaneously. The charging cable of the charging base needs to be connected from the outside to the inside of the charging base. In the traditional way, the charging base is usually divided into two parts: an upper shell and a lower shell. Half holes are set at the parting point on the upper shell and the lower shell for wire harness connection. This is not good for the stability of the wire harness connection, and the half hole positions on the upper shell and the lower shell are relatively weak and easily damaged. Utility Model Content

[0003] The purpose of this utility model is to provide an energy storage base that can stably engage the lead wire, and the position where the energy storage base passes through the lead wire has high strength and is not easily damaged.

[0004] Another objective of this invention is to provide a shared energy storage device with relatively stable lead wires, high operational reliability, and low failure rate.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model discloses an energy storage base, comprising: a housing having a wire passage hole; a fixing head sleeved on the lead wire, wherein the fixing head and the wire passage hole are engaged by an anti-rotation structure to prevent the fixing head from rotating relative to the wire passage hole; and a snap-fit ​​member snapping onto the fixing head and abutting against the inner sidewall of the housing to restrict the axial movement of the fixing head along the wire passage hole.

[0007] In some embodiments, the anti-rotation structure includes a first anti-rotation plane and a second anti-rotation plane, one of which is disposed on the inner sidewall of the wire hole and the other is disposed on the outer sidewall of the fixing head.

[0008] In some embodiments, the anti-rotation structure includes an anti-rotation groove and an anti-rotation protrusion that fits within the anti-rotation groove, wherein one of the anti-rotation groove and the anti-rotation protrusion is disposed on the inner sidewall of the wire hole and the other is disposed on the outer sidewall of the fixing head.

[0009] In some embodiments, a fixing slot is provided on the outer side wall of the fixing head, and the snap-fit ​​member has a fixing insert edge that mates with the fixing slot.

[0010] In some specific embodiments, the fixing slots are arranged in pairs, and the two fixing slots in the pair are symmetrically distributed about the center line of the fixing head. There are two fixing inserts, and the opening formed by the two fixing inserts is a flared mouth.

[0011] In some specific embodiments, the fixed insertion edge is provided with a protrusion, the fixed slot has a stop wall that abuts against the fixed insertion edge, and the protrusion, the stop wall and the inner sidewall of the housing form an interference fit in the receiving space.

[0012] In some embodiments, the fixing head includes a fixing protrusion that abuts against the outer side wall of the housing.

[0013] In some embodiments, a first fixing part is provided on the inner sidewall of the housing, the first fixing part is formed with a fixing groove, and the first end of the snap-fit ​​member is inserted into the fixing groove.

[0014] In some embodiments, the inner sidewall of the housing is further provided with a second fixing part, and the second end of the snap-fit ​​member is provided with a stop flange, which abuts against the second fixing part.

[0015] This utility model also discloses a shared energy storage device, which includes the energy storage base, energy storage support base and multiple energy storage power sources mentioned above. The energy storage support base is installed on the energy storage base, and the multiple energy storage power sources are installed on the energy storage support base.

[0016] The beneficial effects of this utility model are as follows: During actual assembly, after the fixing head is installed into the cable passage hole, the lead wire is passed through the fixing head and led out to the outside of the energy storage base. Then, the snap-fit ​​component engages with the fixing head. Because the fixing head and the cable passage hole are engaged through an anti-rotation structure, the fixing head is prevented from rotating circumferentially around the cable passage hole. Furthermore, because the snap-fit ​​component engages with the fixing head, it prevents the fixing head from moving axially relative to the cable passage hole, ensuring the stability of the fixing head and thus ensuring the stability of the lead wire. In addition, since all the cable passage holes are located on the housing, compared with the semi-hole structure of the prior art, the edge strength of the housing is better, and it is not easy to be damaged.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] This utility model discloses an energy storage base 100, for reference... Figures 1-4 As shown, the energy storage base 100 includes a housing 110, a fixing head 120, and a snap-fit ​​component 130. The housing 110 is provided with a wire passage hole 111. The fixing head 120 is sleeved on the lead wire 140, and the fixing head 120 and the wire passage hole 111 are engaged by an anti-rotation structure to prevent the fixing head 120 from rotating relative to the wire passage hole 111. The snap-fit ​​component 130 is snapped into the fixing head 120 and abuts against the inner sidewall of the housing 110 to restrict the axial movement of the fixing head 120 along the wire passage hole 111. Understandably, during actual assembly, after the fixing head 120 is installed into the wire passage hole 111, the lead wire 140 is passed through the fixing head 120 and led out to the outside of the energy storage base 100. Then, the snap-fit ​​component 130 engages with the fixing head 120. Because the fixing head 120 and the wire passage hole 111 are engaged through an anti-rotation structure, the fixing head 120 is prevented from rotating circumferentially around the wire passage hole 111. Furthermore, because the snap-fit ​​component 130 engages with the fixing head 120, it prevents the fixing head 120 from moving axially relative to the wire passage hole 111, thus ensuring the stability of the fixing head 120 and consequently the stability of the lead wire 140. In addition, since all the wire passage holes 111 are located on the housing 110, compared to the semi-hole structure of the prior art, the edge strength of the housing 110 is better, and it is less prone to damage.

[0040] refer to Figures 3-4 , Figures 10-11 As shown, a fixing slot 122 is provided on the outer wall of the fixing head 120, and the snap-fit ​​member 130 has a fixing insert edge 131 that mates with the fixing slot 122. It can be understood that during actual assembly, after the fixing head 120 is installed into the wire hole 111, the snap-fit ​​member 130 is directly inserted into the fixing head 120 from the inside of the housing 110, so that the fixing insert edge 131 is inserted into the fixing slot 122. After the fixing insert edge 131 and the fixing slot 122 mate, the fixing head 120 cannot move axially along the wire hole 111, ensuring the installation stability of the fixing head 120.

[0041] Optionally, the fixing slots 122 are arranged in pairs, with the two fixing slots 122 symmetrically distributed about the center line of the fixing head 120, and there are two fixing insert edges 131. It can be understood that by setting two fixing slots 122, the fixing head 120 is bilaterally constrained, which helps to improve the installation stability of the fixing head 120.

[0042] Optional, see reference Figures 10-11 As shown, the opening formed by the two fixed insert edges 131 is a flared opening 132. It can be understood that during the insertion of the fixed insert edges 131, since the opening formed by the two fixed insert edges 131 is a flared opening 132, it is convenient for the snap-fit ​​component 130 to be stably inserted into the fixed head 120 to snap the fixed head 120, and it can also ensure the fixing effect of the snap-fit ​​component 130 on the fixed head 120 after it is inserted into the fixed head 120.

[0043] Optional, see reference Figures 10-11 As shown, the fixing insert 131 has a protrusion 1311, and the fixing slot 122 has a stop wall 1221 that abuts against the fixing insert 131. The protrusion 1311, the stop wall 1221, and the inner wall of the housing 110 form an interference fit in the receiving space. It can be understood that during actual installation, when the snap-fit ​​component 130 is snapped into the fixing head 120, the interference fit between the protrusion 1311 on the snap-fit ​​component 130, the stop wall 1221, and the inner wall of the housing 110 effectively prevents the snap-fit ​​component 130 from dislodging from the fixing head 120 when the energy storage base 100 vibrates, thereby reducing the occurrence of fixing head 120 failure. Further optionally, the protrusion 1311 is an elongated protrusion and is integrally formed on the snap-fit ​​component 130 by stamping or injection molding. This improves the installation stability of the snap-fit ​​component 130 and simplifies its manufacturing cost.

[0044] refer to Figure 5As shown, the fixing head 120 includes a fixing protrusion 123, which abuts against the outer wall of the housing 110. It can be understood that during actual installation, when the fixing head 120 is inserted into the wire hole 111, the fixing protrusion 123 abutting against the outer wall of the housing 110 confirms that the fixing head 120 is properly inserted. Then, the snap-fit ​​component 130 is inserted into the fixing head 120. The added fixing protrusion 123 enables the fixing head 120 to be positioned and inserted, facilitating user assembly.

[0045] refer to Figures 6-7 As shown, a first fixing part 112 is provided on the inner side wall of the housing 110, and the first fixing part 112 forms a fixing groove 1121. The first end of the snap-fit ​​member 130 is inserted into the fixing groove 1121. It can be understood that in the actual installation process, when the snap-fit ​​member 130 is inserted into the fixing groove 1121, it means that the snap-fit ​​member 130 is inserted into place. On the one hand, it realizes the precise snap-fit ​​of the snap-fit ​​member 130, and on the other hand, it can fix the snap-fit ​​member 130. This can better prevent the snap-fit ​​member 130 from coming off the fixing head 120 when the energy storage base 100 vibrates, thereby reducing the occurrence of fixing head 120 failure.

[0046] refer to Figures 6-7 As shown, the inner wall of the housing 110 is also provided with a second fixing part 113, and the second end of the snap-fit ​​member 130 is provided with a stop flange 133, which abuts against the second fixing part 113. It can be understood that the second fixing part 113 and the first fixing part 112 form a double-sided fixation for the snap-fit ​​member 130, further preventing the snap-fit ​​member 130 from coming off the fixing head 120 when the energy storage base 100 vibrates, thereby reducing the occurrence of fixing head 120 failure.

[0047] refer to Figures 8-9 As shown, the anti-rotation structure includes a first anti-rotation plane 1111 and a second anti-rotation plane 121. One of the first anti-rotation plane 1111 and the second anti-rotation plane 121 is disposed on the inner sidewall of the wire passage hole 111, and the other is disposed on the outer sidewall of the fixing head 120. It can be understood that when the fixing head 120 is inserted into the wire passage hole 111...

[0048] In an alternative embodiment of this utility model, the anti-rotation structure includes an anti-rotation groove and an anti-rotation protrusion that fits within the anti-rotation groove. One of the anti-rotation groove and the anti-rotation protrusion is disposed on the inner sidewall of the wire passage hole 111, and the other is disposed on the outer sidewall of the fixing head 120. The cooperation of the anti-rotation groove and the anti-rotation protrusion can also restrict the fixing head 120, thereby preventing the fixing head 120 from being installed in the wire passage hole 111. The distribution of the anti-rotation groove and the anti-rotation protrusion can be selected according to actual needs. In some embodiments, the anti-rotation groove is disposed on the inner sidewall of the wire passage hole 111, and the anti-rotation protrusion is disposed on the outer sidewall of the fixing head 120; in some embodiments, the anti-rotation groove is disposed on the outer sidewall of the fixing head 120, and the anti-rotation protrusion is disposed on the inner sidewall of the wire passage hole 111; in some embodiments, both the anti-rotation protrusion and the anti-rotation groove are disposed on the outer sidewall of the fixing head 120, and both the anti-rotation protrusion and the anti-rotation groove are disposed on the inner sidewall of the wire passage hole 111.

[0049] This utility model also discloses a shared energy storage device, see reference. Figure 12 As shown, the shared energy storage device includes the aforementioned energy storage base 100, energy storage support 200, and multiple energy storage power sources 300. The energy storage support 200 is mounted on the energy storage base 100, and the multiple energy storage power sources 300 are mounted on the energy storage support 200. Due to the aforementioned energy storage base 100, the lead wires 140 of this shared energy storage device are relatively stable, have high operational reliability, and a low failure rate.
