Description

Technical Field

[0001] This invention relates to the field of liquid cooling plate positioning technology, and in particular to a liquid cooling plate positioning structure. Background Technology

[0002] With the development of technology and the progress of society, new energy vehicles are becoming increasingly popular. As the requirements for mileage and performance increase, ensuring battery stability becomes particularly important, necessitating cooling of the batteries to ensure their normal operation. Currently, the most ideal solution is liquid cooling, using liquid cooling plates to cool the battery pack, making the liquid cooling plates quite crucial.

[0003] For example, a patent with publication number CN216370585U, entitled "A Pre-positioning Welding Device for Liquid Cooling Plates in Automotive Battery Packs," was published on April 26, 2022. It includes a limiting fixture and a clamping device. The limiting fixture can limit the liquid cooling plate and the flow channel tube, and the clamping device can press the liquid cooling plate and the flow channel tube onto the limiting fixture. This utility model ensures that the relative position of the liquid cooling plate and the flow channel tube is fixed during brazing, preventing product deformation. However, the applicant found that when processing liquid cooling plates of different sizes, if the same fixture is used for positioning, the position of the liquid cooling plate is not easily fixed, reducing the efficiency of producing qualified products. If different sizes of liquid cooling plates are used for positioning, clamping and disassembly are time-consuming and labor-intensive, also reducing the efficiency of producing qualified products. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a liquid cooling plate positioning structure to solve the problem of low efficiency of qualified products.

[0005] To achieve the above objectives, the present invention provides a liquid cooling plate positioning structure, including a base, a placement plate for placing a liquid cooling plate body on the base, a plurality of paired openings on the liquid cooling plate body, a clamping member for fixing the liquid cooling plate body on the placement plate, a movable arm on one side of the placement plate, a positioning member for positioning the liquid cooling plate body connected to the movable arm, the movable arm for moving the positioning member, the positioning member including a positioning plate, two positioning rods that cooperate with the openings on the lower end face of the positioning plate, an extension plate hinged to both sides of the lower end of each positioning rod via a hinge shaft, a torsion spring on the hinge shaft, the two ends of the torsion spring abutting or connecting to the extension plate and the positioning rod respectively.

[0009] Optionally, the upper surface of the extension plate is connected to the positioning rod via a limiting spring at its center.

[0010] Optionally, the limiting spring is fitted with a multi-section protective sleeve on its outer side.

[0011] Optionally, the positioning component includes a connecting plate arranged parallel to the positioning plate, the connecting plate being located between the positioning plate and the moving arm, a plurality of multi-section limiting rods being connected between the positioning plate and the connecting plate, the two ends of the multi-section limiting rods being fixedly connected to the positioning plate and the connecting plate respectively, and a connecting spring located within the multi-section limiting rods being connected between the positioning plate and the connecting plate.

[0012] Optionally, the liquid cooling plate body has multiple elliptical grooves, and elliptical protrusions are provided in the elliptical grooves.

[0021] like Figure 1-9 As shown, a liquid cooling plate positioning structure includes a base 2, on which a placement plate 3 for placing a liquid cooling plate body 1 is provided. The liquid cooling plate body 1 has a plurality of paired openings 103. The placement plate 3 is provided with clamping members for fixing the liquid cooling plate body 1. A movable arm 6 is provided on one side of the placement plate 3. A positioning member 4 for positioning the liquid cooling plate body 1 is connected to the movable arm 6. The movable arm 6 is used to move the positioning member 4. The positioning member 4 includes a positioning plate 5. The lower end face of the positioning plate 5 is provided with two positioning rods 503 that cooperate with the openings 103. Each positioning rod 503 has an extension plate 504 hinged to both sides of its lower end via a hinge shaft. A torsion spring is provided on the hinge shaft. The two ends of the torsion spring abut or connect to the extension plate 504 and the positioning rod 503, respectively.

[0022] When the liquid cooling plate body 1 needs to be processed, it is placed on the placement plate 3. The clamping components on the placement plate 3 pre-clamp the liquid cooling plate body 1. The clamping components include two clamping cylinders and clamping plates connected to each clamping cylinder. The two clamping cylinders control the two clamping plates to move towards each other to pre-clamp the liquid cooling plate body 1. The moving arm 6 controls the positioning component 4 to move, moving the positioning plate 5 to the upper surface of the liquid cooling plate body 1. The lower end face of the positioning rod 503 and the lower end face of the extension plate 504 contact the upper surface of the liquid cooling plate body 1. When both positioning rods 503 are provided with An opening 103 is provided, which facilitates the positioning of the opening 103. The extension plates 504 on both sides of the positioning rod 503 swing upward under the constraint of the side wall of the opening 103. The extension plates 504 press and fix the opening 103 under the action of the torsion spring. In addition, when the positioning plate 5 moves horizontally, it is convenient to detect the flatness of the liquid cooling plate body 1 through the positioning rod 503 and the extension plates 504. When the liquid cooling plate body 1 has a protrusion, the positioning rod 503 and the extension plates 504 will be lifted, indicating that the liquid cooling plate body 1 is not flat. This facilitates the detection of unqualified products and improves the efficiency of processing qualified products.

[0023] The movable arm 6 is connected to the base 2 via a rotating component. The rotating component includes a rotating motor connected to the base 2. The output end of the rotating motor is connected to a vertically arranged rotating shaft. The upper end of the rotating shaft is connected to the movable arm 6. When the rotating motor is started, it can drive the rotating shaft to rotate, thereby realizing the control of the rotation of the movable arm 6.

[0024] The movable arm 6 includes multiple adjacent connected arm segments. Two adjacent arm segments are connected by an adjusting member. The adjusting member includes an adjusting motor. The output end of the adjusting motor is connected to an adjusting shaft. The side wall of the adjusting shaft and the adjusting motor are respectively connected to two adjacent arm segments. When the adjusting motor is started, it drives the adjusting shaft to rotate, adjusting the angle between two adjacent arm segments, thereby realizing the adjustment and control of the positioning member 4 by the movable arm 6, and being able to adjust the up-down, left-right, and forward-backward movement of the positioning member 4.

[0025] The extension plate 504 is arc-shaped at one end near the positioning rod 503. A limiting groove 507 is provided at the end of the extension plate 504 near the positioning rod 503. A limiting plate 506 is provided on the side wall of the positioning rod 503 to cooperate with the limiting groove 507, so as to limit the extension plate 504 from being lower than the lower end of the positioning rod 503.

[0026] The limiting groove 507 includes a first groove and a connected second groove. The bottom of the first groove is at the same distance from the axis of the hinge shaft. The distance between the bottom of the second groove connected to the first groove and the axis of the hinge shaft is greater than the distance between the bottom of the second groove away from the first groove and the axis of the hinge shaft. The limiting plate 506 facilitates the limitation of the extension plate 504 from continuing to swing downward when it is perpendicular to the positioning rod 503. When the extension plate 504 swings upward counterclockwise, the limiting plate 506 can move in the limiting groove 507.

[0027] The upper end face of the extension plate 504 is connected to the positioning rod 503 via a limiting spring 505, which allows the extension plate 504 to remain perpendicular to the positioning rod 503 when there is no other force pushing it.

[0028] The limiting spring 505 is fitted with a multi-section protective sleeve on its outer side to facilitate the protection of the limiting spring 505.

[0029] The positioning component 4 includes a connecting plate 7 arranged parallel to the positioning plate 5. The connecting plate 7 is located between the positioning plate 5 and the moving arm 6. Multiple multi-section limiting rods 8 are connected between the positioning plate 5 and the connecting plate 7. The two ends of the multi-section limiting rods 8 are fixedly connected to the positioning plate 5 and the connecting plate 7, respectively. A connecting spring 9 located inside the multi-section limiting rods 8 is connected between the positioning plate 5 and the connecting plate 7 for positioning the paired openings 103. When there are openings 103 below both positioning rods 503, the positioning plate 5 moves downward to facilitate the positioning of the openings 103. In addition, when the positioning plate 5 moves on the liquid cooling plate body 1, it is also convenient to detect the flatness of the liquid cooling plate body 1. When there is a protrusion on the surface of the liquid cooling plate body 1, the positioning plate 5 is lifted up, indicating that the liquid cooling plate body 1 is not flat.

[0030] The liquid cooling plate body 1 has multiple elliptical grooves, and elliptical protrusions 101 are provided in the elliptical grooves. The upper end surface of the elliptical protrusions 101 is higher than the upper end surface of the liquid cooling plate body 1. Elliptical annular grooves 102 are provided outside the elliptical protrusions 101 and located in the elliptical grooves. Two pairs of openings 103 are respectively located on both sides of the elliptical grooves. The lower end surface of the positioning plate 5 is provided with two arc-shaped strips 501 located between the two positioning rods 503. The two arc-shaped strips 501 are used to fix the elliptical protrusions 101. The coverage of the arc-shaped strips 501 is smaller than that of the positioning rods 503. When the positioning plate 5 moves on the liquid cooling plate body 1, when the two openings 103 are engaged with the two positioning rods 503, the positioning plate 5 moves downward, and the two positioning rods 503 are respectively inserted into the two openings 103. The two arc-shaped strips 501 move to both sides of the elliptical protrusions 101 to restrict them.

[0031] The positioning rod 503 is connected to the lower end face of the positioning plate 5 via the pad 502. The height of the pad 502 is the same as that of the arc strip 501, so that when the positioning rod 503 is inserted into the opening 103, the arc strip 501 does not need to be inserted into the elliptical groove. The arc strip 501 only needs to restrict the elliptical protrusion 101.

[0032] Both of the two arc-shaped strips 501 are provided with inclined guide blocks at their lower ends. The inclined surfaces of the two inclined guide blocks are arranged facing each other. The thickness of the lower part of the inclined guide block is less than the thickness of the upper part of the inclined guide block. The lower end face of the positioning plate 5 is provided with two sliding grooves that are slidably connected to the two arc-shaped strips 501 respectively. The upper part of each arc-shaped strip 501 is connected to the side wall of the sliding groove by an elastic spring. The two elastic springs are located on the opposite side of the two arc-shaped strips 501. When the distance between the two arc-shaped strips 501 is less than the length of the elliptical protrusion 101, and the two positioning rods 503 are respectively inserted into the two openings 103, the two arc-shaped strips 501 move obliquely downwards. The two arc-shaped strips 501 move to both sides of the elliptical protrusion 101 to restrict it.
