[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] Embodiment 1

[0036] The present embodiment relates to a magnetic ring bracket, which is helpful to improve the convenience and stability of the installation of the magnetic ring 2 and is conducive to the mass production of the project.

[0037] In terms of overall structure, Figure 1 As shown, the magnetic ring bracket of this embodiment includes a base 1 for connecting to the battery pack shell, blocking portions 3 arranged on both sides of the base 1 in the width direction, and a through hole 12 penetrating the base 1 along the width direction of the base 1.

[0038] The two blocking portions 3 and the base 1 together form an installation cavity 11 for installing the magnetic ring 2 , and the insertion hole 12 is used to pass a strap 21 for tightening the magnetic ring 2 in the installation cavity 11 .

[0039] Here, by providing the blocking portion 3 on both sides of the base 1 in the width direction, the blocking portion 3 and the base 1 are enclosed to form an installation cavity 11 for installing the magnetic ring 2, and the binding strap 21 for binding the magnetic ring 2 in the installation cavity 11 is passed through the through-hole 12 that penetrates the base 1 along the width direction of the base 1. The structure is simple and easy to arrange, which is conducive to improving the stability of the installation of the magnetic ring 2. The binding strap 21 in this embodiment adopts a binding product well known to those skilled in the art, such as a nylon tie.

[0040] The magnetic ring 2 is a common power accessory that plays an anti-interference role in the circuit and can prevent the electromagnetic interference inside the battery pack from affecting other devices. In specific implementation, the circular hole through which the wire harness passes is wrapped around the magnetic ring 2, and then the magnetic ring 2 is placed in the installation cavity 11, and then the binding band 21 is passed through the through hole 12 to tighten the magnetic ring 2 in the installation cavity 11.

[0041] Based on the above overall introduction, in this embodiment, as a preferred implementation form, Figure 1As shown, each blocking portion 3 includes two blocking plates 31 spaced apart along the length direction of the base 1, and the through hole 12 is located between the two blocking plates 31 in each side blocking portion 3. In addition, each blocking plate 31 is slidably disposed on the base 1 along the width direction of the base 1.

[0042] With this arrangement, the width of the installation cavity 11 can be adjusted, thereby increasing the flexibility and stability of the device, which is beneficial to improving the application range of the bracket.

[0043] In addition, in this embodiment, as a preferred implementation form, Figure 4 As described above, an elastic member 32 is provided between the baffle 31 and the base 1. The elastic member 32 is preferably a spring, which is a mature product and is conducive to reducing the risk of use, and can also realize the elastic clamping of the baffle 31 on the magnetic ring 2, which is conducive to improving the convenience and stability of installation.

[0044] At the same time, refer to Figure 3 As shown, the two baffles 31 in each side blocking portion 3 are connected by a connecting member 13. The setting of the connecting member 13 can improve the stability of the structure. It is worth mentioning that in order to achieve the lightweight design of the magnetic ring bracket of this embodiment, a weight reduction area can be added if necessary. In the specific structure, for example, a weight reduction hole 131 is opened on the connecting member 13.

[0045] Secondly, as a preferred implementation form, Figure 1 and Figure 2 As shown, the magnetic ring 2 is cylindrical. In addition, the base 1 is provided with an arc groove 111 located in the installation cavity 11 , the arc groove 111 is extended along the length direction of the base 1 , and the arc groove 111 is used to place the magnetic ring 2 .

[0046] By providing the arc groove 111, the shaking of the magnetic ring 2 can be reduced after the magnetic ring 2 is placed in the arc groove 111, thereby improving the stability of the installation. The base 1 is provided with a connecting groove 14 that penetrates the thickness of the base 1. The connecting groove 14 is located in the circular groove and is connected to the insertion hole 12, which is convenient for the strap 21 to be inserted, thereby improving the convenience of operation.

[0047] Furthermore, in this embodiment, as a preferred implementation form, Figure 3 and Figure 4 As shown, the base 1 is provided with a connecting groove 14 that penetrates the base 1 through its thickness. The connecting groove 14 is located in the arc groove 111 and is connected to the insertion hole 12. This arrangement facilitates the insertion of the strap 21 and improves the convenience of operation.

[0048] In addition, as a preferred embodiment, Figures 2 to 4As shown, the bottom of the base 1 of this embodiment is provided with a card connector 15 for card connection with the battery pack shell, and the card connector 15 is connected to the base 1 through a connecting plate 16 located in the connecting groove 14. The advantage of such a setting is that a detachable connection can be formed, the operation is simple, and it is convenient for subsequent maintenance and replacement.

[0049] In specific implementation, the card connector 15 can be arranged in the middle of the bottom of the base 1, thereby improving the stability of the structure. It is worth mentioning that when the connecting plate 16 is not provided, the card connector 15 can be arranged on the peripheral side of the connecting groove 14, and the number of the card connector 15 can be set and adjusted accordingly according to actual needs. In this embodiment, it is preferably set to one.

[0050] In addition, in this embodiment, as a preferred implementation form, see Figure 4 As shown, support portions 17 are respectively provided at both ends of the base 1 in the length direction, and the support portions 17 are used to support the base 1 when the base 1 is engaged with the battery pack shell.

[0051] Support parts 17 are provided at both ends of the base 1 in the length direction to support the base 1 when the base 1 and the battery pack shell are clamped together, thereby improving the reliability of the connection by tightening.

[0052] It is worth mentioning that, in addition to being suitable for cylindrical magnetic rings, the magnetic ring bracket of the present embodiment can also be used to fix magnetic rings of other shapes, such as square magnetic rings, that is, rectangular parallelepiped. In the specific implementation, the retaining portion 3 is first slid out along the width direction of the base 1, allowing the wiring harness to pass through the circular hole of the square magnetic ring and be wrapped around the square magnetic ring. After the square magnetic ring is placed in the installation cavity 11 (at this time, the arc groove 111 is located at the bottom of the square magnetic ring, and the arc groove 111 cannot play a role in pre-positioning and avoiding shaking), the retaining portion 3 is then slid in to fix the square magnetic ring (of course, the provision of the elastic member 32 can save manpower to slide the retaining portion 3 into the installation cavity 11), and the magnetic ring is fixed to the bracket by passing the binding strap 21 through the insertion hole 12 and the connecting groove 14, so that the magnetic ring bracket is not limited to fixing cylindrical magnetic rings, that is, the scope of application of the magnetic ring bracket is increased.

[0053] The magnetic ring bracket involved in this example is provided with a base 1 connected to the battery pack shell, and retaining parts 3 and insertion holes 12 are provided on both sides of the base 1 in the width direction. In specific implementation, each retaining part 3 can be slid out along the width direction of the base 1, and the magnetic ring 2 with the wrapped wiring harness can be placed in the installation cavity 11, and the strap 21 is passed through the insertion hole 12 and the connecting groove 14 to fix the magnetic ring 2 on the bracket, and then the bracket is fixed to the battery pack shell through the clamping joint 15 at the bottom, so as to reduce the shaking amount of the magnetic ring 2 during installation, improve the convenience and stability of the installation of the magnetic ring 2, and facilitate the mass production of the project.
