Description

Technical Field

[0001] This invention relates to the field of new energy battery testing technology, specifically a testing device for new energy batteries. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. In pure electric vehicles, the battery plays a crucial role as the energy source, so the battery needs to be tested when inspecting new energy vehicles.

[0003] Currently, battery testing requires precise positioning of the battery. A test indenter is then slowly pressed down on the battery surface from top to bottom, causing deformation. The depth of the indenter's movement is controlled by a computer, while sensors on the equipment transmit data such as battery voltage, capacity, and temperature. Depending on the purpose, the pressure can be increased to the point of spontaneous combustion, with pressure levels as low as 1mm or 2mm. This testing process is inherently dangerous and can easily lead to fire or explosion. Summary of the Invention

[0004] This invention addresses the aforementioned shortcomings of existing technologies by providing a testing device for new energy batteries. The device secures the battery to a fastening frame and a support frame for testing, and raises a protective cover when the battery is in position to ensure testing safety.

[0005] To achieve the above objectives, the invention provides the following technical solution:

[0006] A testing device for new energy batteries includes a workbench and a test head. A support frame for placing the battery is installed on the workbench. The support frame is provided with a fastening frame that cooperates with it and is used to prevent the battery from rotating. The fastening frame is movably connected to the test head.

[0007] A discharge port is provided on one side of the workbench. A sealing plate for blocking the discharge port is installed on the lower side of the workbench via a connecting rod assembly. A rack that moves up and down along the workbench is installed on one side of the connecting rod assembly. The support frame is rotatable relative to the workbench. A gear assembly is provided on one side of the workbench. After the support frame is rotated, it drives the gear assembly to transmit power. The gear assembly meshes with the rack.

[0008] Preferably, the support frame is provided with a semi-circular ring, and a rubber ring matching its shape is provided inside the semi-circular ring. A pressure rod that contacts the rubber ring is provided on one side of the fastening frame.

[0009] Preferably, there is a gap between the upper part of the rubber ring and the semi-circular ring, and one end of the pressure rod is a pointed tip that can be inserted into the gap.

[0010] Preferably, the test head is provided with a mounting plate on one side, and the fastening bracket is fitted on the outside of the test head and located on the mounting plate.

[0011] Preferably, the linkage assembly includes a support rod and a linkage rod. The support rod is provided on the lower side of the worktable, and the linkage rod is movably installed at the lower end of the support rod. One end of the linkage rod contacts the sealing plate, and the other end is movably connected to the rack.

[0012] Preferably, the support frame is provided with a counterweight in the middle.

[0013] Preferably, the workbench is equipped with a protective cover, which includes a vertical plate and a baffle.

[0014] Preferably, the vertical plate has a C-shaped structure, and a baffle is provided on one side of the vertical plate; a connecting rope is provided on one side of the baffle, and the connecting rope passes through the fastening frame and connects to the mounting plate.

[0015] Preferably, a coil spring is fitted on one side of the baffle, and the coil spring is connected to the connecting rope.

[0016] Preferably, the gear assembly includes a large gear and a small gear, the large gear is connected to the support frame, and the small gear meshes with the rack; the outer end of the support frame is connected to the vertical plate bearing, and one end of the support frame is provided with a large gear.

[0017] Compared with existing technologies, the beneficial effects of the invention are:

[0018] 1. The present invention has a reasonable structural design. By moving the test head, it can not only perform the detection action of pressing into the battery surface, but also fix the position of the battery to ensure the accuracy of the test results. It can also be used in conjunction with the vertical plate and fastening frame after the baffle is raised to improve the safety of the test.

[0019] The test head moves the fastening frame, and the fastening frame uses its own weight to make the pressure rod engage with the rubber ring, thereby fastening the battery end between the fastening frame and the support frame through the rubber ring, preventing the battery from rotating when the test head contacts the battery surface, and improving the stability of use.

[0020] Furthermore, once the fastening frame and support frame are engaged, the test head continues to move without interference from the fastening frame. The continued movement of the test head causes the connecting rope to move the baffle upwards, thus creating a protective shield between the baffle and the vertical plate to protect the testing personnel.

[0021] Furthermore, since the connecting rope is connected to the baffle via a coil spring, when the baffle and the vertical plate work together for protection, even if the test head continues to move for testing, the connecting rope will cause the coil spring to tighten. The coil spring provides the connecting rope with a range of movement, thus ensuring that the connecting rope will not be broken due to excessive movement and improving the reliability of use.

[0022] 2. After the test of this invention is completed, the scrapped batteries need to be collected. At this time, the support frame is rotated. The support frame drives the rack to move through the gear assembly. The movement of the rack drives the linkage rod to move. The inner end of the linkage rod moves downward, so that the sealing plate opens under its own weight and the battery leaves from the discharge port.

[0023] In the gear assembly, the large gear is connected to the support frame, while the small gear meshes with the rack. Therefore, the rotation of the large gear will drive the small gear to rotate more times, thus allowing the rack to move a sufficient distance to drive the linkage rod to move, ensuring the opening effect of the sealing plate.

[0024] A counterweight is installed in the middle of the support frame to prevent the support frame from rotating arbitrarily. This ensures that the gear assembly and rack do not change position, thereby ensuring that the connecting rod assembly does not change the use state of the sealing plate and ensuring the sealing effect of the sealing plate on the discharge port during the test.

Detailed Implementation

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1

[0036] A testing device for new energy batteries, such as Figures 1-8 As shown, it includes a workbench 1 and a test head 2. A support frame 3 for placing batteries is installed on the workbench 1. A fastening frame 4 that cooperates with the support frame 3 and is used to prevent the batteries from rotating is provided on the support frame 3. A semi-circular ring 31 is provided on the support frame 3. A rubber ring 32 that matches the shape of the semi-circular ring 31 is provided inside the semi-circular ring 31. A pressure rod 41 that contacts the rubber ring 32 is provided on one side of the fastening frame 4.

[0037] A gap is provided between the upper part of the rubber ring 32 and the semi-circular ring 31, and one end of the pressure rod 41 is pointed and can be inserted into the gap. The test pressure head 2 drives the fastening frame 4 to move. The fastening frame 4 uses its own weight to make the pressure rod 41 cooperate with the rubber ring 32, thereby fastening the end of the battery between the fastening frame 4 and the support frame 3 through the rubber ring 32, preventing the battery from rotating when the test pressure head 2 contacts the battery surface, and improving the stability of use.

[0038] The fastening bracket 4 is movably connected to the test head 2; a mounting plate 21 is provided on one side of the test head 2, and the fastening bracket 4 is fitted onto the outside of the test head 2 and located on the mounting plate 21. In this way, when the fastening bracket 4 is engaged with the support frame 3, the continued movement of the test head 2 will not be affected by the fastening bracket 4.

[0039] A discharge port 5 is provided on one side of the workbench 1, and a sealing plate 6 for blocking the discharge port 5 is installed on the lower side of the workbench 1 via a connecting rod assembly. The sealing plate 6 is movably connected to the discharge port 5, and the sealing plate 6 can fall under its own weight without external support, thereby opening the discharge port 5.

[0040] The linkage assembly includes a support rod 71 and a linkage rod 72. The support rod 71 is provided on the lower side of the worktable 1. The linkage rod 72 is movably installed at the lower end of the support rod 71. One end of the linkage rod 72 is in contact with the sealing plate 6, and the other end is movably connected to the rack 8.

[0041] A rack 8 that moves up and down along the worktable 1 is installed on one side of the connecting rod assembly. The support frame 3 is rotatable relative to the worktable 1. A gear assembly is provided on one side of the worktable 1. After the support frame 3 is rotated, it drives the gear assembly to transmit power. The gear assembly meshes with the rack 8.

[0042] After the test, the scrapped batteries need to be collected. At this time, the support frame 3 is rotated. The support frame 3 drives the rack 8 to move through the gear assembly. The movement of the rack 8 drives the linkage rod 72 to move. The inner end of the linkage rod 72 moves downward, so that the sealing plate 6 opens under its own weight, and the battery leaves from the discharge port 5.

[0043] The gear assembly includes a large gear 91 and a small gear 92. The large gear 91 is connected to the support frame 3, and the small gear 92 meshes with the rack 8. The outer end of the support frame 3 is connected to the bearing of the vertical plate 101, and the large gear 91 is provided at one end of the support frame 3.

[0044] Therefore, the rotation of the large gear 91 will drive the small gear 92 to rotate more times, thereby allowing the rack 8 to move a sufficient distance to drive the linkage rod 72 to move, ensuring the opening effect of the sealing plate 6.

[0045] When using this device, place the battery on the support frame 3, start the test head 2, and the fastening frame 4 moves with the test head 2 under its own weight until the pressure rod 41 and the rubber ring 32 cooperate to fix the battery between the support frame 3 and the fastening frame 4.

[0046] At the same time, the movement of the test head 2 causes the connecting rope 104 to move, thereby flipping the baffle 102 and making the baffle 102 cooperate with the vertical plate 101. The fastening frame 4 is located on the upper side of the baffle 102, thus forming a protective cover for the test space and conducting tests on the test personnel.

[0047] After the test, the test head 2 is removed from the battery and the baffle 102 is not opened to prevent natural gas or smoke from escaping and affecting the operating environment. The tester rotates the support frame 3 on one side of the vertical plate 101, and the battery on the support frame 3 falls onto the sealing plate 6.

[0048] At the same time, the support frame 3 rotates, driving the large gear 91 to rotate. The large gear 91 drives the rack 8 to move upward through the small gear 92. The movement of the rack 8 drives the outer end of the linkage rod 72 to move upward, that is, the inner end of the linkage rod 72 moves downward and no longer supports the sealing plate 6. The sealing plate 6 falls under its own weight, thereby opening the discharge port 5.

[0049] Example 2

[0050] The support frame 3 is provided with a counterweight 33 in the middle. The counterweight 33 prevents the support frame 3 from rotating arbitrarily, thereby preventing the gear assembly and rack 8 from changing, and thus ensuring that the connecting rod assembly does not change the use state of the sealing plate 6, and ensuring the sealing effect of the sealing plate 6 on the discharge port 5 during the test.

[0051] The gear assembly may be provided with a housing on the outside, which can protect the gear assembly from external impacts that could damage it, or prevent debris from falling into the gear assembly and affecting the meshing between the components.

[0052] Example 3

[0053] The workbench 1 is equipped with a protective cover, which includes a vertical plate 101 and a baffle 102. The protective cover protects the test personnel. Before use, the open baffle 102 facilitates the test personnel in placing the battery. During use, the fastening frame 4, the vertical plate 101, and the baffle 102 form a sealed space to prevent spontaneous combustion or explosion of the battery from injuring the test personnel.

[0054] The vertical plate 101 has a C-shaped structure, and a baffle 102 is provided on one side of the vertical plate 101. A connecting rope 104 is provided on one side of the baffle 102, and the connecting rope 104 passes through the fastening frame 4 and connects to the mounting plate 21 (or the horizontal plate on which the test pressure head 2 is mounted). A coil spring 103 is fitted on one side of the baffle 102, and the coil spring 103 is connected to the connecting rope 104.

[0055] After the fastening frame 4 and the support frame 3 are engaged, the test pressure head 2 continues to move without being interfered with by the fastening frame 4. The continued movement of the test pressure head 2 causes the connecting rope 104 to move the baffle 102 upward, thereby forming a protective shield between the baffle 102 and the vertical plate 101 to protect the test personnel.

[0056] Because the connecting rope is connected to the baffle via a coil spring, when the baffle and the vertical plate work together for protection, even if the test head continues to move for testing, the connecting rope will cause the coil spring to tighten. The coil spring provides the connecting rope with a range of movement, thus ensuring that the connecting rope will not be broken due to excessive movement and improving the reliability of use.

[0057] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
