Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a new energy battery test bench. Background Technology

[0002] There are five types of batteries for new energy vehicles: lithium cobalt oxide batteries, lithium iron phosphate batteries, nickel-metal hydride batteries, ternary lithium batteries, and graphene batteries. Electric vehicles are currently a hot topic, and batteries are a crucial factor restricting their development. Many sectors are seeking technological breakthroughs to achieve a leading position.

[0003] After the production of new energy vehicle batteries is completed, test benches are usually used to fix the batteries in place. For example, Chinese utility model patent CN219224854U relates to the field of new energy vehicle battery testing technology and discloses a new energy vehicle battery test bench, including a base and a first U-shaped frame. The first U-shaped frame is located on the top outer wall of the base. The first U-shaped frame is connected to a drive shaft via a bearing. One end of the drive shaft is connected to a worm gear. A flipping component is installed on one outer wall of the first U-shaped frame and meshes with the worm gear. A second U-shaped frame is rotatably connected to the inner wall of the first U-shaped frame. Through the flipping component, drive shaft, and worm gear, the flipping component drives the worm gear to rotate. The worm gear drives the second U-shaped frame to flip through the drive shaft, thus facilitating the flipping test of the battery without the need for manual secondary clamping and flipping. The output end of a second motor drives a first pulley to rotate. The first pulley drives the second pulley to rotate through a drive belt. A second threaded rod and a third threaded rod drive the first U-shaped frame to move, thus facilitating movement and adjustment in conjunction with testing equipment.

[0004] However, some problems still exist. Although the worm gear drives the second U-shaped frame to rotate through the transmission shaft, which facilitates the rotation test of the battery, the worm gear will wear down after long-term use. It also needs to drive the electric push rod to rotate, which increases the power required for rotation and is inconvenient. Therefore, a new energy battery test bench is proposed to solve the above problems. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a new energy battery test bench.

[0006] This utility model proposes a new energy battery test bench, which includes a frame and a clamping mechanism installed on the frame for clamping the battery. Unlike the prior art, the clamping mechanism includes a first telescopic member installed on the frame. The telescopic end of the first telescopic member is rotatably connected to a first clamping plate. A second clamping plate is rotatably installed on the frame. The second clamping plate and the first clamping plate are used to clamp the battery.

[0007] It also includes a turntable mounted on the frame, the axis of rotation of the turntable relative to the frame coincides with the axis of rotation of the first clamping plate relative to the first telescopic member, a connecting member is provided between the turntable and the first clamping plate, and the turntable drives the first clamping plate to rotate through the connecting member.

[0008] During battery testing, the battery is first placed between the first clamp and the second clamp. The battery is then fixed between the first clamp and the second clamp by extending the first telescopic member. The battery is then flipped by rotating the turntable to drive the first clamp and the second clamp to rotate. During this process, the first telescopic member does not rotate with the battery.

[0009] As a further optimization of this utility model, the connector is a connecting column, one end of which is fixed to the first clamping plate, and the other end of which is slidably mounted on the turntable.

[0010] During the process of the first telescopic member moving the first clamping plate, the connecting column slides relative to the turntable, and when the turntable rotates, the turntable drives the first clamping plate to rotate through the connecting column.

[0011] As a further optimization of this utility model, the displacement of the connecting column relative to the turntable is parallel to the axis of the turntable.

[0012] The movement of the first clamping plate also calibrates the displacement of the second clamping plate.

[0013] As a further optimization of this utility model, a limiting member is provided at the end of the connecting column away from the first clamping plate, and the limiting member is used to limit the displacement of the first clamping plate relative to the turntable.

[0014] The limiting member can restrict the movement and displacement of the first clamping plate.

[0015] As a further optimization of this utility model, it also includes a drive mechanism for driving the turntable to rotate.

[0016] The drive mechanism can be a gear transmission mechanism or other drive mechanism that can drive the turntable to rotate, which can reduce the labor intensity of workers to a certain extent.

[0017] As a further optimization of this utility model, a first extension post for initially limiting the battery is slidably installed laterally on the first clamping plate, and a first elastic member is provided between the first extension post and the first clamping plate. The first elastic member can undergo elastic deformation along the displacement direction of the first extension post relative to the first clamping plate.

[0018] The first elastic element can be a spring in the prior art. When the battery is placed between the first clamping plate and the second clamping plate, the battery contacts the first extension post. When the first telescopic element drives the first clamping plate to move closer to the second clamping plate, the first elastic element deforms, thereby causing the portion of the first extension post extending out of the first substrate to gradually shorten.

[0019] As a further optimization of this utility model, when the first telescopic member drives the first clamping plate to contact the battery, the first extension column slides into the first clamping plate, and the first telescopic mechanism stops operating, thereby avoiding excessive squeezing force of the first and second clamping plates on the battery.

[0020] As a further optimization of this utility model, a support plate is installed on the first clamping plate, and a second clamping plate is slidably installed on the support plate. The displacement of the second clamping plate relative to the support plate is parallel to the axis of rotation of the second clamping plate relative to the frame.

[0021] The support plate facilitates initial support of the battery, and the second clamp slides relative to the support plate as the first clamp moves closer to the second clamp.

[0022] As a further optimization of this utility model, the axis of rotation of the second clamping plate relative to the frame coincides with the axis of rotation of the first clamping plate relative to the first telescopic member.

[0023] This further facilitates the flipping of the battery between the first and second clamping plates.

[0024] As a further optimization of this utility model, it also includes a second telescopic member, which is mounted on the frame, and the second clamping plate is rotatably mounted on the telescopic end of the second telescopic member.

[0025] This further facilitates clamping the battery.

[0026] In this utility model, the proposed new energy battery test bench, through the arrangement of the first clamping plate, the second clamping plate, the turntable and the connecting parts mounted on the frame, facilitates the first telescopic part not to rotate with the first clamping plate during the rotation of the first clamping plate and the second clamping plate, and the first clamping plate can be moved without the turntable moving, so that the rotation of the turntable can drive the first clamping plate to move.

[0027] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] like Figure 1-3 The diagram shows a new energy battery test bench, including a frame 1 and a clamping mechanism mounted on the frame 1 for clamping the battery. The clamping mechanism is used to clamp the battery and includes a first telescopic member 2 mounted on the frame 1. The first telescopic member 2 can be an electric cylinder, a pneumatic cylinder, or other components that can drive a plate-shaped component to move horizontally. In this embodiment, the first telescopic member 2 is an electric cylinder. The telescopic end of the first telescopic member 2 is rotatably connected to a first clamping plate 3. Specifically, the telescopic end of the first telescopic member 2 can be fixed to a mounting plate, and the first clamping plate 3 can be rotatably mounted on the mounting plate to achieve the lateral rotation of the first clamping plate 3 on the first telescopic member 2. A second clamping plate 4 is rotatably mounted on the frame 1. The first telescopic member 2 is used to drive the first clamping plate 3 to move horizontally. The first clamping plate 3 and the second clamping plate 4 are arranged opposite to and parallel to each other. The second clamping plate 4 and the first clamping plate 3 are used to clamp the battery.

[0034] It also includes a turntable 5 installed on the frame 1. The axis of rotation of the turntable 5 relative to the frame 1 coincides with the axis of rotation of the first clamping plate 3 relative to the first telescopic member 2. A connecting member 6 is provided between the turntable 5 and the first clamping plate 3. The turntable 5 drives the first clamping plate 3 to rotate through the connecting member 6.

[0035] Specifically, the frame 1 has a vertical plate 10, the turntable 5 is horizontally rotatably mounted on the vertical plate 10, and the first telescopic member 2 is mounted on the vertical plate 10. In this embodiment, in order to reduce the footprint of the entire device, a through hole is opened in the middle of the turntable 5, the first telescopic member 2 passes through the through hole, and the through hole of the turntable 5 is larger than the maximum size of the first telescopic member 2, so that the turntable 5 will not interfere with the first telescopic member 2 during rotation.

[0036] During the battery testing process, the battery is first placed between the first clamping plate 3 and the second clamping plate 4. The battery is then fixed between the first clamping plate 3 and the second clamping plate 4 by extending the first telescopic member 2. Then, the battery is flipped by rotating the turntable 5 to drive the first clamping plate 3 and the second clamping plate 4 to rotate. During this process, the first telescopic member 2 does not rotate with the battery. Compared with the existing technology, which requires the telescopic mechanism to rotate during the battery flipping process, this reduces energy loss to a certain extent.

[0037] In this embodiment, specifically, the connecting member 6 is a connecting column. One end of the connecting column is fixed on the first clamping plate 3, and the other end of the connecting column is slidably mounted on the turntable 5. The turntable 5 has a sliding hole, and the connecting column passes through the sliding hole and is horizontally slidably connected to the turntable 5. The connection position between the connecting column and the turntable 5 is offset relative to the axis of the turntable 5. The displacement of the connecting column relative to the turntable 5 is parallel to the axis of the turntable 5. When the first telescopic member 2 drives the first clamping plate 3 to move, the connecting column slides relative to the turntable 5. When the turntable 5 rotates, the turntable 5 drives the first clamping plate 3 to rotate through the connecting column. The sliding hole matches the connecting column. Thus, when the first telescopic member 2 drives the first clamping plate 3 to move horizontally, the sliding hole and the connecting column calibrate the horizontal movement of the first telescopic member 2.

[0038] In this embodiment, preferably, a limiting member 7 is provided at the end of the connecting column away from the first clamping plate 3. The limiting member 7 is used to limit the displacement of the first clamping plate 3 relative to the turntable 5. The limiting member 7 can be a nut that can be detachably installed on the limiting column. The outer diameter of the limiting member 7 is larger than the diameter of the sliding hole. The limiting member 7 can be used to limit the displacement of the first clamping plate 3.

[0039] Preferably, the system also includes a drive mechanism for rotating the turntable 5. In this embodiment, the drive mechanism includes a motor 9 mounted on the frame 1 and a gear transmission mechanism 8. The driving gear is mounted on the frame 1, and the motor 9 drives the driving gear to rotate. The driven gear ring is sleeved on the outside of the turntable 5 and meshes with the driving gear. When the motor 9 drives the driving gear to rotate, the turntable 5 is rotated through the driven gear ring. This reduces the labor intensity of the workers to a certain extent.

[0040] Preferably, a first extension post 11 for initially limiting the battery is slidably mounted on the first clamping plate 3. The first clamping plate 3 has a sliding hole, and the first extension post 11 is slidably mounted in the sliding hole. A first elastic member 12 is provided between the first extension post 11 and the first clamping plate 3. The first elastic member 12 can be a spring in the prior art. The first elastic member 12 can elastically deform along the displacement direction of the first extension post 11 relative to the first clamping plate 3. After the first telescopic member 2 drives the first clamping plate 3 to move away from the second clamping plate 4, the first extension post 11 returns to its original position and extends out of the first clamping plate 3 under the action of the first elastic member 12. The first extension post 11 has a portion located between the first clamping plate 3 and the second clamping plate 4.

[0041] When the battery is placed between the first clamping plate 3 and the second clamping plate 4, the battery contacts the first extension post 11. As the first telescopic member 2 moves the first clamping plate 3 closer to the second clamping plate 4, the first elastic member 12 deforms, causing the portion of the first extension post 11 extending out of the first substrate to gradually shorten.

[0042] In some preferred embodiments, when the first telescopic member 2 drives the first clamping plate 3 to contact the battery, the first extension post 11 slides into the first clamping plate 3, and the first telescopic mechanism stops operating, thereby avoiding excessive squeezing force on the battery by the first clamping plate 3 and the second clamping plate 4.

[0043] In some specific embodiments, the first extension post 11 has a protrusion 110 and a touch switch 13 in the sliding hole. When the first extension post 11 extends completely into the sliding hole in the first clamping plate 3, the protrusion 110 contacts the touch switch 13, and the touch switch 13 controls the first telescopic member 2 to stop moving. Specifically, the touch switch 13 can be connected in series in the circuit of the first telescopic member 2 and the power supply.

[0044] In some preferred embodiments, a support plate 14 is mounted on the first clamping plate 3, and a second clamping plate 4 is slidably mounted on the support plate 14. The displacement of the second clamping plate 4 relative to the support plate 14 is parallel to the axis of rotation of the second clamping plate 4 relative to the frame 1. The support plate 14 facilitates the initial support of the battery. When the first clamping plate 3 moves closer to the second clamping plate 4, the second clamping plate 4 slides relative to the support plate 14. During the rotation of the first clamping plate 3, the support plate 14 drives the second clamping plate 4 to rotate, reducing the force between the second clamping plate 4 and the battery.

[0045] Preferably, the axis of rotation of the second clamping plate 4 relative to the frame 1 coincides with the axis of rotation of the first clamping plate 3 relative to the first telescopic member 2, which further facilitates the flipping of the battery between the first clamping plate 3 and the second clamping plate 4.

[0046] As a further optimization of this utility model, it also includes a second telescopic member 15, which is mounted on the frame 1. The second clamping plate 4 is rotatably mounted on the telescopic end of the second telescopic member 15. The second telescopic member 15 can be an electric cylinder, a pneumatic cylinder, or other components capable of driving horizontal movement of parts, such as... Figure 1 The second telescopic member 15 shown is an electric cylinder. The first telescopic member 2 and the second telescopic member 15 drive the movement of the first clamping plate 3 and the second clamping plate 4, thereby facilitating the clamping of the battery.

[0047] It should be noted that, in order to achieve the pre-tightening force on the battery and control the closing of the first telescopic member 2, the structure on the second clamping plate 4 is the same as the structure on the first clamping plate 3.

[0048] It should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
