Description

Technical Field

[0001] The utility model relates to the field of new energy battery collection systems, in particular to a metal collection piece and a positioning seat for positioning the metal collection piece. Background Art

[0002] Under the dual carbon goals, people's demand for power and energy storage batteries is increasing, and the new energy market has entered a stage of rapid development. Power batteries mostly use acquisition harnesses to collect the temperature and voltage signals of the batteries inside the module. The acquisition harnesses include flexible printed circuits (FPC) and flexible flat cables (FFC). In the prior art, the SMT method is often used to weld the FPC or FFC to the metal acquisition sheet. When the FPC or FFC needs after-sales service due to abnormal acquisition, the FPC or FFC cannot be replaced by welding, and the entire battery pack can only be scrapped, and the after-sales cost remains high.

[0003] Therefore, in recent years, a connection method that uses a connection mechanism to achieve a detachable connection between the FPC or FFC and the metal collection sheet has gradually emerged. This connection method can achieve convenient, fast and non-destructive replacement of the FPC or FFC for maintenance, greatly reducing after-sales costs. However, using a connection mechanism to achieve a detachable connection between the FPC or FFC and the metal collection sheet may result in inaccurate relative positioning between the metal collection sheet and the FPC or FFC, as well as poor contact between the metal collection sheet and the FPC or FFC, thereby affecting the connection reliability between the two.

[0004] Therefore, the utility model proposes a metal collection piece and a positioning seat for positioning the metal collection piece to solve the above-mentioned problems. Utility Model Content

[0010] On the other hand, the utility model also provides a positioning seat, which is used to position the metal collection piece described in any of the above items, and the positioning seat includes a base plate, and a positioning groove for accommodating the positioning part is provided at the middle position of the upper surface of the base plate, and an opening is provided at one end of the positioning groove, and the bottom upper surface of the positioning groove is provided in a bent shape to form a bearing convex strip that cooperates with the contact convex strip; a plurality of vertical protrusions that cooperate with the limiting through hole are provided in the positioning groove, and / or at least one side of the positioning groove is provided with a lateral protrusion that cooperates with the limiting groove.

[0011] Furthermore, a plurality of the vertical protrusions are arranged in sequence along the bearing protrusions.

[0012] Furthermore, there are four vertical protrusions and they are all elliptical, the lengths of the two middle vertical protrusions are greater than the lengths of the two side vertical protrusions, and end positioning protrusions are provided on one end of the two middle vertical protrusions close to the opening extending upward.

[0013] Furthermore, the lateral protrusions are provided in two numbers and are symmetrically arranged on two sides of the positioning groove close to the opening.

[0014] Furthermore, in the absence of external force, there is a first gap between an end of the positioning portion away from the opening and a side wall of the positioning groove, and / or a second gap between the bottom of the positioning portion and an upper surface of the bottom of the positioning groove.

[0015] Furthermore, positioning slots and / or positioning hooks connected to the external clamping assembly are also provided on the bottom plates on both sides of the positioning groove.

[0016] Beneficial effects of the utility model:

[0017] (1) By providing a structure of a limiting through hole and / or a limiting groove on the metal collection sheet and cooperating with an external positioning seat, the position of the metal collection sheet can be accurately limited, and the external positioning seat can also accurately position the external FPC or FFC, thereby ensuring that the relative position between the metal collection sheet and the external FPC or FFC is accurately positioned; and, by providing an upwardly protruding contact ridge on the metal collection sheet, that is, the contact ridge protrudes in the direction of the external FPC or FFC, it is helpful for the metal collection sheet to achieve good contact with the FPC or FFC through the contact ridge, thereby ensuring the reliability of the connection between the two.

DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0030] Example 1

[0031] like Figures 1 to 7 As shown, this embodiment provides a metal collection sheet 1, which includes a main body 11 and a positioning portion 12 extending at one end of the main body 11, the main body 11 is straight, the positioning portion 12 is bent and forms an upwardly protruding contact ridge 13, a plurality of limiting through holes 14 are provided in the positioning portion 12, and / or a limiting groove 15 is provided on at least one side of the positioning portion 12.

[0032] In this embodiment, by providing a limiting through hole 14 and / or a limiting groove 15 on the metal collection sheet 1 and cooperating with the external positioning seat 2, the position of the metal collection sheet 1 can be accurately limited, and the external positioning seat 2 can also accurately position the external FPC or FFC 8, thereby ensuring that the relative position between the metal collection sheet and the external FPC or FFC 8 is accurate; and, by providing an upwardly protruding contact ridge 13 on the metal collection sheet 1, that is, the contact ridge 13 protrudes in the direction of the external FPC or FFC 8, it is helpful for the metal collection sheet 1 to achieve good and stable contact with the FPC or FFC8 through the contact ridge 13, thereby ensuring the reliability of the connection between the two.

[0033] Furthermore, a plurality of the limiting through holes 14 are sequentially arranged along the contact ridge 13. Specifically, the positioning portions 12 located on both sides of the contact ridge 13 are bent downward by 1 to 10 degrees relative to the horizontal plane, preferably by 4 to 5 degrees, and the bending angle should not be too large to prevent stress concentration. Long-term stress concentration may cause metal fatigue and form micro cracks and fractures.

[0034] In this embodiment, a plurality of the limiting through holes 14 are sequentially arranged along the contact protrusion 13. By rationally arranging the positions of the contact protrusion 13 and the limiting through holes 14, not only the structure is made more compact, but also the stress at the bending part of the contact protrusion 13 is helped to be released along the limiting through holes 14, thereby further avoiding the occurrence of stress concentration.

[0035] Furthermore, there are four limiting through holes 14, all of which are elliptical, and the lengths of the two middle limiting through holes 14 are greater than the lengths of the two side limiting through holes 14. In this embodiment, by setting the limiting through holes 14 to be elliptical, it is helpful to reduce the friction between the limiting through holes 14 and the external positioning seat 2, thereby reducing the wear of the positioning seat 2 on the metal collection sheet 1 and extending the service life.

[0036] Furthermore, there are two limiting grooves 15 symmetrically arranged on both sides of the positioning portion 12. In this embodiment, by symmetrically arranging the limiting grooves 15 on both sides of the positioning portion 12, the force on the metal collection sheet can be balanced, and the positioning effect is better. Specifically, the limiting grooves 15 are arc-shaped grooves, which can also reduce the friction between the limiting grooves 15 and the external positioning seat 2, thereby reducing the wear of the positioning seat 2 on the metal collection sheet 1 and extending the service life.

[0037] Example 2

[0038] like Figures 1 to 7 As shown, the utility model also provides a positioning seat 2, which is used to position the metal collection piece 1 described in any one of the embodiments 1, and the positioning seat includes a bottom plate 21, and a positioning groove 22 for accommodating the positioning portion 12 is provided at the middle position of the upper surface of the bottom plate 21, and an opening 26 is provided at one end of the positioning groove 22, and the bottom upper surface of the positioning groove 22 is provided in a bent shape and forms a bearing convex strip 23 that matches the contact convex strip 13; the positioning groove 22 is provided with a plurality of vertical protrusions 24 that match the limiting through hole 14, and / or at least one side of the positioning groove 22 is provided with a lateral protrusion 25 that matches the limiting groove 15. Specifically, the two sides of the positioning groove 22 are also provided with lateral positioning grooves 28 and / or lateral positioning blocks 29 that match the external FPC or FFC 8 for positioning.

[0039] In this embodiment, the positioning seat 2 can accurately define the position of the metal collection piece 1 by providing a positioning groove 22, a vertical protrusion 24, and a lateral protrusion 25 that cooperate with the positioning portion 12 in the metal collection piece 1. At the same time, the external positioning seat 2 can also accurately position the external FPC or FFC 8, thereby ensuring that the relative position between the metal collection piece and the external FPC or FFC 8 is accurately positioned; at the same time, the bottom upper surface of the positioning groove 22 in the positioning seat 2 also forms a bearing convex strip 23 accordingly to match the shape of the metal collection piece 1 and better carry the metal collection piece 1; and, an opening 26 is provided at one end of the positioning groove 22 to facilitate the main body 11 of the metal collection piece 1 to extend outward.

[0040] Furthermore, a plurality of the vertical protrusions 24 are sequentially arranged along the bearing protrusions 23 to correspond to the positions of the limiting through holes 14 in the positioning portion 12 .

[0041] Furthermore, there are four vertical protrusions 24 and they are all elliptical. The lengths of the two middle vertical protrusions 24 are greater than the lengths of the two side vertical protrusions 24 , and end positioning protrusions 27 are extended upward from one end of the two middle vertical protrusions 24 close to the opening 26 .

[0042] In this embodiment, the vertical protrusion 24 is set to an elliptical shape to adapt to the shape of the limiting through hole 14, and it helps to reduce the friction between the limiting through hole 14 and the vertical protrusion 24, thereby reducing the wear between the metal collection plate 1 and the positioning seat and extending the service life. Specifically, the four vertical protrusions 24 are set flush at one end away from the opening 26, the ends of the two middle vertical protrusions 24 close to the opening 26 are longer than the two side vertical protrusions 24, and the end positioning protrusion 27 is extended above the part where the two middle vertical protrusions 24 are longer than the two side vertical protrusions 24; since the external FPC or FFC 8 is set at one end of the positioning seat 2 away from the opening 26, by setting the end positioning protrusion 27, the end of the external FPC or FFC 8 can be effectively limited, and at the same time, the end positioning protrusion 27 is set integrally on the two middle vertical protrusions 24, which can make the structure of the positioning seat more compact.

[0043] Furthermore, the lateral protrusions 25 are provided in two and symmetrically arranged on both sides of the positioning groove 22 near the opening 26. In this embodiment, by providing two lateral protrusions 25 to cooperate with the two limiting grooves 15 in the positioning portion 12, the metal collection sheet 1 can be subjected to balanced force and have a better positioning effect. Specifically, the lateral protrusions 25 are arc-shaped protrusions, which can also reduce the friction between the limiting grooves 15 and the lateral protrusions 25, thereby reducing the wear of the positioning seat 2 and the metal collection sheet 1 and extending the service life.

[0044] Furthermore, in the absence of external force, there is a first gap 3 between the end of the positioning portion 12 away from the opening 26 and the side wall of the positioning groove 22, and / or a second gap 4 between the bottom of the positioning portion 12 and the bottom upper surface of the positioning groove 22.

[0045] In the present embodiment, after the metal collecting sheet 1 is installed, when the metal collecting sheet 1 is not subjected to external force, there is a first gap 3 and / or a second gap 4 between the positioning groove 22 and the metal collecting sheet 1. When the metal collecting sheet 1 is subjected to a downward pressing force, the metal collecting sheet 1 will undergo elastic deformation, and the first gap 3 and / or the second gap 4 provide sufficient space for the elastic deformation, thereby preventing the metal collecting sheet 1 from undergoing uncontrollable deformation due to insufficient elastic deformation space.

[0046] Furthermore, the bottom plate 21 on both sides of the positioning groove 22 is also provided with positioning grooves 5 and / or positioning hooks 6 connected to the external clamping assembly 7. In this embodiment, by providing the positioning groove 22 with the positioning groove 5 and / or positioning hooks 6, it is convenient for the positioning groove 22 to be detachably connected with the external clamping assembly 7.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
