Detailed Description

In order to make the technical solution of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings and specific embodiments.

Without loss of generality, the embodiment of the present application uses the output pole support assembly 100 shown in fig. 1 as a description basis, and details an implementation scheme of an assembly clamping structure between an output pole support and a fixing member. It should be understood that the particular functional structure of the output pole is not central to the subject utility model and is not a substantial limitation of the output pole support assembly claimed herein.

Referring to fig. 1 and 2, fig. 1 is a schematic diagram illustrating an assembly relationship formed by a side view of an output pole support assembly according to the present embodiment, and fig. 2 is a schematic diagram illustrating a direction a of a fixing member shown in fig. 1.

As shown, the output pole support assembly 100 includes a snap-fit output pole support 10 and a mount 20. The output electrode mount 10 includes a first mounting portion 11, and the first mounting portion 11 is usable for mounting and fixing the electrode-side FPC (Flexible Printed Circuit, flexible circuit board) 30. The fixture 20 may be a high pressure mount for better integration of the assembly of the components; in other embodiments, the fixing element 20 may be a separately provided component of the battery device, as long as the functional requirement of the snap-fit connection with the output pole support 10 is met.

It will be appreciated that the particular configuration of the first mounting portion 11 may be determined based on the overall design requirements of the particular product and is not limited to the configuration shown in the figures.

Here, in order to clearly describe the specific structure of the output pole support and the assembly relationship thereof, a direction in which the output pole support 10 is clamped and slid with respect to the fixing member 20 is defined as a first direction X; a plane perpendicular to the first direction X is defined as a mounting reference plane, and the second direction Y and the third direction Z are defined as two different directions lying within the mounting reference plane.

In this embodiment, the output pole support 10 includes a first clamping structure 12, the first clamping structure 12 includes two first clamping portions 121 disposed along the second direction Y, the first clamping portions 121 are fixed on the first mounting portion 11 through the connecting portion 122, and the extending directions of the two first clamping portions 121 are opposite. The two first engaging portions 121 are shown extending opposite each other.

Correspondingly, the fixing piece 20 includes a first concave portion 21 adapted to the first clamping structure 12, two side walls of the first concave portion 21 are respectively provided with a first limiting portion 211, and two first limiting portions 211 of the fixing piece 20 are disposed in one-to-one correspondence with two first clamping portions 121 of the output pole support 10, and extend in opposite directions along the second direction Y.

The first engaging portion 121 may be disposed in the first concave portion 21, and form a first engaging pair with the corresponding first limiting portion 211, so as to limit the output pole support 10 from being separated from the fixing member 20 in the third direction Z. That is, a limit between the two is formed in the third direction Z. Specifically, after the first clamping structures 12 on the output pole support 10 are aligned with the first concave portions 21 along the first direction X, the first clamping structures 12 on the output pole support 10 can move towards the fixing piece 20 along the first direction X, and the two first clamping structures 12 on the output pole support 10 can slide along the corresponding first limiting portions 211 respectively, and are reliably attached to the inner side surfaces of the first limiting portions 211 after reaching the mounting position, so that a first clamping fit pair is formed.

Based on the two first engaging portions 121 on the output electrode support 10 side and the two first limiting portions 211 on the fixing member 20 side, better bearing strength is obtained between the two first engaging portions. In the use, can effectively block the structure and appear damaging the inefficacy problem such as, have better joint reliability. In addition, after the assembly is completed, the first clamping structure 12 of the output pole support 10 is built in the fixing piece 20, the space size occupation is not increased due to the construction of the first clamping proper matching pair, and the overall integration level is high.

In this embodiment, the first concave portion 21 of the fixing member 20 has therein a reinforcing rib 212 extending in the first direction X to increase the structural strength. Correspondingly, a rib accommodating groove 123 is formed between the two first clamping parts 121 of the output pole support 10 so as to accommodate the reinforcing rib 212 on the side of the fixing piece 20 after clamping connection; that is, the fitting accommodation structure of the reinforcing rib 212 is provided on the output pole support 10 side while constructing the first card fitting pair, without affecting the assembly integration.

In a specific implementation, the first clamping structures 12 may be arranged at intervals along the second direction Y as required, and the bearing strength of the clamping adaptation relationship is improved by increasing the first limiting pair.

In other specific implementations, the two first engaging portions 121 of the first engaging structure 12 may also extend in opposite directions along the second direction Y, and correspondingly, the two first limiting portions 211 of the fixing member 20 extend in opposite directions along the second direction Y (not shown in the drawing), so that a first suitable mating pair of the first card with reliable connection can be formed in the third direction Z.

In order to further improve the reliability of the assembly relationship between the output pole support 10 and the fixing piece 20, a second suitable mating pair of the second clamp can be further added, that is, a stop limit is formed in the first direction X.

The overhanging end of the elastic arm comprises a stop protrusion 131, and the stop protrusion 131 protrudes out of the body of the second clamping structure 13. Here, in the second direction Y, the second engagement structure 13 is located beside the first engagement structure 12.

Accordingly, the fixing member 20 includes a second concave portion 22, and the second concave portion 22 has a second limiting portion 221 extending in the third direction X, as shown in fig. 1 and 3, where the second concave portion 22 is disposed opposite to the second engaging structure 13.

The retaining protrusion 131 may be disposed in the second concave portion 22, and form a second snap fit pair with the corresponding second limiting portion 221, so as to limit the output pole support 10 from being separated from the fixing member 20 in the first direction X. Specifically, in the process of moving the output electrode support 10 along the first direction X toward the fixing member 20, the edge of the second limiting portion 221 may press against the elastic arm of the second clamping structure 13 to deform, until the retaining protrusion 131 moves to the inner side of the second concave portion 22, the elastic arm of the second clamping structure 13 is no longer pressed against by the second limiting portion 221, and returns under the action of the stored elastic deformation energy, where the retaining protrusion 131 abuts against the inner side surface of the second limiting portion 221, so as to form a second suitable matching pair of the second clamp. Referring also to fig. 5, a cross-sectional view of the mating relationship of the second card mating pair is shown in an embodiment.

Based on the retaining protrusion 131 on the output pole support 10 side and the second limiting portion 221 on the fixing member 20 side, the output pole support 10 can be prevented from reversely retreating from the fixing member 20, and the stability of the clamping and matching relationship between the two can be prevented from being affected.

Of course, in other specific implementations, the second fastening structure 13 may also be disposed beside the first mounting portion 11 (not shown in the drawings), that is, outside the body of the first mounting portion 11. It should be appreciated that the specific location of the second clamping structure 13 may be configured according to actual needs, as long as the function of the backstop protrusion 131 can be provided.

Based on the guide slope 1311, jamming can be avoided, and operability is improved.

It will be appreciated that the guiding inclined surface may be a guiding surface of other shapes, such as, but not limited to, a guiding curved surface, and can also cooperate with the edge of the second limiting portion 221 to avoid jamming, and is not limited to the inclined surface shown in the drawings.

Meanwhile, the two second positioning portions 152 of the second mounting portion 14 may form a fourth card mating pair with the corresponding fourth limiting portion 232, so as to form a limit in the third direction Z.
