Description

Technical Field

[0001] This utility model relates to the field of battery technology, and more specifically, to a waterproof component, a waterproof connector, and a battery. Background Technology

[0002] The energy storage battery includes a battery casing, a battery module, and a battery management system, with the battery module and battery management system housed within a cavity in the battery casing. A connector is provided on the battery casing, penetrating the casing to allow the battery module to connect to an external circuit.

[0003] Because there are gaps between the mounting slots and connectors on the battery casing, the seal between the connectors and the battery casing is not good, and dust, moisture and other substances can easily enter the casing. Therefore, in order to ensure the waterproof effect of the battery casing, waterproof connectors are usually used or glue is poured into the mounting slots to seal the gaps.

[0004] However, applying glue makes it difficult to replace the connector. To ensure easy replacement, waterproof connectors are often chosen to seal the gaps. Different sizes of waterproof connectors are required for different mounting slots, which is time-consuming and labor-intensive. Furthermore, waterproof connectors can only meet the lower waterproof requirements of the battery casing, resulting in poor waterproof performance of the battery casing with waterproof connectors. Utility Model Content

[0005] The main objective of this invention is to provide a waterproof component, a waterproof connector, and a battery to solve the problem of poor waterproof performance of battery casings in the prior art.

[0006] To achieve the above objectives, according to a first aspect of the present invention, a waterproof component is provided, suitable for a connector for insertion into a socket in a first mounting groove on a battery cover. The waterproof component includes: a first plate on which the connector is disposed; a waterproof ring on which the connector is disposed and surrounds the connector; waterproof ribs are provided on the circumferential sidewalls of the waterproof ring so that when the connector is inserted into the socket, the first plate passes through the first mounting groove to seal the portion of the first mounting groove away from the battery cover; wherein, when the waterproof ring is inserted into the first mounting groove, the waterproof ribs abut against the groove wall of the first mounting groove.

[0007] Furthermore, the first mounting groove includes a first groove segment and a second groove segment that are connected to each other. The first groove segment and the second groove segment are arranged sequentially along the depth direction of the first mounting groove. Along the depth direction of the first mounting groove, the projected area of ​​the first groove segment on the battery cover is smaller than the projected area of ​​the second groove segment on the battery cover. The socket is disposed in the first groove segment, and the second groove segment is disposed close to the battery cover relative to the first groove segment, so that when the connector is inserted into the socket, the first plate is inserted into the second groove segment to block the first groove segment.

[0008] Furthermore, the first plate includes an upper end face and a lower end face that are disposed opposite to each other along the depth direction of the first mounting groove. The waterproof ring and the connector are both disposed on the lower end face so that when the connector is inserted into the socket, the lower end face abuts against the bottom wall of the second groove segment, and the upper end face is disposed flush with the surface of the battery cover.

[0009] Furthermore, waterproof reinforcing strips are arranged around the circumferential sidewall of the waterproof ring, and the extension direction of the waterproof reinforcing strips is perpendicular to the depth direction of the first mounting groove.

[0010] Furthermore, there are multiple waterproof reinforcing strips, which are spaced apart on the circumferential sidewall of the waterproof ring along the depth direction of the first mounting groove.

[0011] Furthermore, the waterproof component also includes a connector, which is disposed on the upper end surface of the first plate. The connector has a connecting channel for passing through the connector wire.

[0012] Furthermore, the waterproof ring, the first plate, and the connector are injection molded as a single unit.

[0013] Furthermore, the waterproof ring, the first plate, and the connectors are all made of silicone.

[0014] According to a second aspect of the present invention, a waterproof connector is provided, comprising a connector, a terminal block body, and the aforementioned waterproof component, wherein a connector of the waterproof component is used to connect to the terminal block body to enable electrical connection between the connector and the terminal block body.

[0015] According to a third aspect of the present invention, a battery is provided, comprising a battery compartment, a battery cover, and the aforementioned waterproof connector.

[0016] The waterproof component of this invention includes a first plate and a waterproof ring. The waterproof ring surrounds the connector and is disposed on the first plate. Waterproof ribs are provided on the circumferential sidewalls of the waterproof ring. When the connector is inserted into the socket, the waterproof ribs pass through the first plate and into the first mounting groove to seal the portion of the first mounting groove away from the battery cover (i.e., the groove where the socket is located), preventing moisture from entering the battery through the first mounting groove. Simultaneously, as the waterproof ring is inserted into the first mounting groove, the waterproof ribs abut against the groove wall of the first mounting groove, allowing the waterproof ribs to seal the gap between the first mounting groove and the waterproof ring, preventing moisture from entering the battery through the gap between the first mounting groove and the waterproof ring. This improves the waterproof effect of the battery casing on which the waterproof component of this invention is installed, thus solving the problem of poor waterproof effect of battery casings in the prior art.

[0028] Please refer to Figures 1 to 5 This utility model provides a waterproof component suitable for a connector 1. The connector 1 is used to insert into a socket 3 in a first mounting groove on a battery cover 7. The waterproof component includes: a first plate 10, on which the connector 1 is disposed; a waterproof ring 20, on which the waterproof ring 20 is disposed and surrounds the connector 1. The circumferential sidewall of the waterproof ring 20 extends along the depth direction of the first mounting groove. A waterproof rib 21 is provided on the circumferential sidewall of the waterproof ring 20 so that when the connector 1 is inserted into the socket 3, the first plate 10 passes through the first mounting groove to seal the portion of the first mounting groove away from the battery cover 7. The waterproof ring 20 is inserted into the first mounting groove, and the waterproof rib 21 abuts against the groove wall of the first mounting groove.

[0029] The waterproof component of this utility model includes a first plate 10 and a waterproof ring 20. The waterproof ring 20 is disposed around the connector 1 on the first plate 10. Waterproof ribs 21 are provided on the circumferential sidewall of the waterproof ring 20. When the connector 1 is inserted into the socket 3, the waterproof ring 20 passes through the first plate 10 and into the first mounting groove to seal the part of the first mounting groove away from the battery cover 7 (i.e., the groove where the socket is located), preventing moisture from entering the battery through the first mounting groove. At the same time, as the waterproof ring 20 is inserted into the first mounting groove, the waterproof ribs 21 abut against the groove wall of the first mounting groove, so that the waterproof ribs 21 can seal the gap between the first mounting groove and the waterproof ring 20, preventing moisture from entering the battery through the gap between the first mounting groove and the waterproof ring 20. This improves the waterproof effect of the battery casing installed with the waterproof component of this utility model, thereby solving the problem of poor waterproof effect of the battery casing in the prior art.

[0030] Specifically, connector 1 is a male connector. The waterproof component of this utility model can solve the problem of poor waterproof effect of mass-produced battery shells, achieve IPX7 waterproof rating for battery shells, and improve the product reliability of batteries. When there is no suitable waterproof connector on the market or the waterproof connector is too large to use, a non-waterproof connector can be directly selected, and then the waterproof component can be installed on the non-waterproof connector to meet the waterproof requirements of the battery shell.

[0031] In this embodiment, the first mounting groove includes a first groove segment 2 and a second groove segment 4 that are connected to each other. The first groove segment 2 and the second groove segment 4 are arranged sequentially along the depth direction of the first mounting groove. Along the depth direction of the first mounting groove, the projected area of ​​the first groove segment 2 on the battery cover 7 is smaller than the projected area of ​​the second groove segment 4 on the battery cover 7. The socket 3 is disposed in the first groove segment 2, and the second groove segment 4 is disposed close to the battery cover 7 relative to the first groove segment 2, so that when the connector 1 is inserted into the socket 3, the first plate 10 passes through the second groove segment 4 to block the first groove segment 2.

[0032] Specifically, the waterproof ring 20 is inserted into the first groove section 2, the waterproof rib 21 abuts against the groove wall of the first groove section 2, and the second groove section 4 is used to accommodate the first plate 10. The first plate 10 passes through the second groove section 4, so that the first plate 10 covers the first groove section 2 to seal the first groove section 2 and prevent moisture from entering the battery after entering the first groove section 2.

[0033] In this embodiment, the first plate 10 includes an upper end surface 11 and a lower end surface 12 that are disposed opposite to each other along the depth direction of the first mounting groove. The waterproof ring 20 and the connector 1 are both disposed on the lower end surface 12 so that when the connector 1 is inserted into the socket 3, the lower end surface 12 and the bottom groove wall of the second groove segment 4 abut against each other. The upper end surface 11 and the surface of the battery cover 7 are disposed flush with each other.

[0034] Specifically, when the connector 1 is inserted into the socket 3, it abuts against the bottom wall of the second slot 4 through the lower end face 12, ensuring that the first plate 10 can fully block the first slot 2.

[0035] In this embodiment, the waterproof reinforcing strip 21 is arranged around the circumferential sidewall of the waterproof ring 20, and the extending direction of the waterproof reinforcing strip 21 is perpendicular to the depth direction of the first mounting groove.

[0036] Specifically, this arrangement ensures that the waterproof reinforcing strip 21 can abut against the groove wall at various points of the first groove section 2, and that the waterproof reinforcing strip 21 can fully and completely seal the gap between the first groove section 2 and the waterproof ring 20.

[0037] In this embodiment, there are multiple waterproof reinforcing bars 21, which are spaced apart on the circumferential sidewall of the waterproof ring 20 along the depth direction of the first mounting groove.

[0038] Specifically, multiple waterproof ribs 21 can jointly seal the gap between the first groove section 2 and the waterproof ring 20, further preventing moisture from entering the battery through the gap between the first groove section 2 and the waterproof ring 20, and further ensuring the waterproof effect of the battery casing on which the waterproof component of this utility model is installed.

[0039] In this embodiment, the waterproof ring 20, the first plate 10, and the connector 30 are injection molded as a single unit.

[0040] Specifically, this utility model uses a waterproof ring 20, a first plate 10, and a connector 30 injection molded onto the male connector. After the connector 1 is inserted into the socket 3, the first plate 10 directly seals the first groove segment 2. This method avoids the problems of increased price and insufficient space caused by customizing waterproof connectors due to waterproof requirements.

[0041] In this embodiment, the waterproof ring 20, the first plate 10, and the connector 30 are all made of silicone. This arrangement ensures the waterproof reliability of the waterproof ring 20, the first plate 10, and the connector 30.

[0042] This utility model also provides a waterproof connector, including a connector 1, a terminal block body 5 and the aforementioned waterproof component. The connector 30 of the waterproof component is used to connect with the terminal block body 5 so that the connector 1 and the terminal block body 5 are electrically connected.

[0043] Specifically, the waterproof connector also includes an external connector 8, which is used to connect to external electrical appliances. The two ends of the terminal block 5 are connected to the external connector 8 and the connector 1, respectively.

[0044] In this embodiment, the waterproof component also includes a connector 30, which is disposed on the upper end face 11 of the first plate 10. The connector 30 has a communication channel inside, which is used to pass through the connecting wire of the connector 1.

[0045] Specifically, the connector 30 is used to connect with the terminal block 5, so that the connecting wires in the terminal block 5 and the connecting wires of the connector 1 are connected to each other through a communication channel, so that the current in the connecting wires of the connector 1 can be transmitted to the connecting wires of the external connector 8 through the connecting wires in the terminal block 5.

[0046] Specifically, after the external connector 8, the terminal block 5, and the connector 1 are soldered together, a waterproof ring 20, a first plate 10, and a connector 30 are injection molded onto the connector 1 to form a single waterproof connector. Then, during production, after the connector 1 is inserted into the socket 3, the first plate 10 is inserted into the second groove 4, so that the first plate 10 and the second groove 4 are interference-fitted to form a seal.

[0047] This utility model also provides a battery, including a battery compartment 6, a battery cover 7, and the aforementioned waterproof connector.

[0048] Specifically, during assembly, the terminal block 5 is first placed into the battery cover 7, and then the first plate 10 is inserted into the second slot 4 to achieve a seal.

[0049] Specifically, the battery of this invention is applicable to electric bicycles, electric scooters, electric-assisted bicycles, outdoor energy storage, and consumer electronics.

[0050] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0051] The waterproof component of this utility model includes a first plate 10 and a waterproof ring 20. The waterproof ring 20 is disposed around the connector 1 on the first plate 10. Waterproof ribs 21 are provided on the circumferential sidewall of the waterproof ring 20. When the connector 1 is inserted into the socket 3, the waterproof ring 20 passes through the first plate 10 and into the first mounting groove to seal the part of the first mounting groove away from the battery cover 7 (i.e., the groove where the socket is located), preventing moisture from entering the battery through the first mounting groove. At the same time, as the waterproof ring 20 is inserted into the first mounting groove, the waterproof ribs 21 abut against the groove wall of the first mounting groove, so that the waterproof ribs 21 can seal the gap between the first mounting groove and the waterproof ring 20, preventing moisture from entering the battery through the gap between the first mounting groove and the waterproof ring 20. This improves the waterproof effect of the battery casing installed with the waterproof component of this utility model, thereby solving the problem of poor waterproof effect of the battery casing in the prior art.

[0052] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
