Description

Technical Field

[0001] This utility model relates to the field of battery testing equipment technology, and in particular to a power battery testing device. Background Technology

[0002] Power battery testing devices are specialized equipment used to evaluate and monitor battery performance, health status, and safety. With the rapid development of electric vehicles, energy storage systems, and other fields, the demand for high-performance and high-reliability power batteries is increasing, and the corresponding testing technologies are becoming increasingly important.

[0003] In the prior art, such as Chinese Patent No. CN222379730U, "A Power Battery Testing Device", a base and a test pen fixing device are included. Support columns are installed at the four corners of the top of the base. A top plate is fixedly connected between the four support columns. An instrument mounting base is installed on the top of the top plate. A battery positioning device is provided on the top of the base. The battery positioning device includes three first guide rails, which are respectively set on both sides and the back of the top of the base. A sliding rod is slidably connected inside the first guide rail. The side of the sliding rod near the center of the base passes through the first guide rail and is fixedly connected to a limit plate. A slot is opened on the top of the first guide rail. A positioning mechanism is provided on the top of the first guide rail at the position corresponding to the slot. This utility model replaces the traditional manual method of measuring voltage with a test pen, greatly reducing the labor intensity of the staff and thus improving work efficiency.

[0004] The aforementioned technologies, while enabling precise control of the horizontal and vertical positions of the fixed sleeve to ensure that the test pen inside the fixed sleeve can touch the positive and negative terminals of the power battery when falling vertically, thus replacing manual testing, still require testing one battery at a time before removing it to test another when multiple batteries need to be tested, which consumes a lot of time. Furthermore, when testing multiple batteries simultaneously, if a problem occurs, it is necessary to locate one or more damaged batteries, which is also very time-consuming. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that when multiple batteries need to be tested, one battery still needs to be tested before another can be removed for testing. When multiple batteries are tested simultaneously, if a problem occurs, it is still necessary to find one or more damaged batteries.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a power battery testing device, comprising: a base, a rotating shaft movably connected to the top of the base, a turntable sleeved on the outer surface of the rotating shaft, two fixing blocks I fixedly connected to both sides of the turntable, a linkage shaft sleeved on the outer surface of the two fixing blocks I, a fixing block II fixedly connected to the other side of each of the two linkage shafts, a connecting strip fixedly connected to the top of each of the two fixing blocks II, and a slider fixedly connected to both sides of each of the two connecting strips.

[0007] In a preferred embodiment, a plurality of fixing strips are fixedly installed on the top of the base, and sliding grooves are provided on both sides of the plurality of fixing strips. A plurality of sliders are slidably connected to the outer surface of the plurality of fixing strips. An electric push rod is fixedly installed on the top of the base, and a push plate is fixedly connected to the output end of the electric push rod. The push plate is fixedly connected to the outer surface of one side of one of the sliders. A base plate is fixedly connected to the top of each of the two connecting strips, and a fixing frame is fixedly installed on the top of each of the two base plates.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: When the electric push rod is activated, the output end of the electric push rod drives the push plate to move. The movement of the push plate causes the slider to slide on the outer surface of the sliding groove. The sliding of the slider causes the connecting strip to move synchronously. Since the two linkage shafts are connected to the fixed block on the outer surface of the turntable, the movement of the connecting strip causes the turntable to rotate on the outer surface of the shaft. However, since the turntable is limited by the angle of the linkage shaft, the rotation angle of the turntable is limited to 180 degrees. The rotation of the turntable causes the two linkage shafts to move in opposite directions. Therefore, the two connecting strips move synchronously in opposite directions. The movement of the connecting strips causes the entire base plate to move.

[0009] In a preferred embodiment, the device further includes a plurality of battery tubes, each of which has a detection line fixedly connected to one side and a sensor block fixedly connected to the other side of each of the detection lines. Detection plates are fixedly installed on the other side of each of the two fixed frames, and a plurality of sensor lights are fixedly connected to the outer surface of each of the two detection plates. Detection blocks are fixedly connected to the top of each of the plurality of detection plates.

[0010] The technical effect of adopting the above-mentioned further solution is that when the battery is inserted into the inside of one of the battery tubes, the movement of the base plate causes the two battery tubes on both sides to connect, causing the two ends of the battery to be inserted into the two battery tubes respectively. The positive and negative terminals of the battery are connected to the detection line and the information is transmitted to the inside of the detection block through the sensing block.

[0011] In a preferred embodiment, a cylindrical frame is fixedly installed on one side of the base, a motor is fixedly installed on the top of the cylindrical frame, the output shaft of the motor is fixedly connected to a motor threaded rod, a nut block is movably sleeved on the outer surface of the motor threaded rod, a support bar is fixedly connected to one side of the nut block, two telescopic lines are fixedly connected to both sides of the support bar, a detection head is fixedly installed on the other side of each of the two telescopic lines, and two detection lights are fixedly installed on the top of each support bar.

[0012] The technical effect of adopting the above-mentioned further solution is as follows: when the motor is started, the output shaft of the motor drives the motor threaded rod to rotate, causing the nut block to move on the outer surface of the motor threaded rod. The movement of the nut block drives the support bar to move. The staff manually pulls the telescopic line to insert the detection head into the inside of the detection block for detection. The condition of the battery is judged by observing the detection light. If the battery is damaged, the damaged battery can be found by using the sensor light.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In use, the electric push rod is activated, and its output end drives the push plate to move. The movement of the push plate causes the slider to slide on the outer surface of the sliding groove. The sliding of the slider causes the connecting strip to move synchronously. Since the two linkage shafts are connected to the fixed block on the outer surface of the turntable, the movement of the connecting strip causes the turntable to rotate on the outer surface of the shaft. However, due to the angle limitation of the linkage shaft, the rotation angle of the turntable is limited to 180 degrees. The rotation of the turntable causes the two linkage shafts to move in opposite directions, so the two connecting strips move synchronously in opposite directions. The movement of the connecting strips causes the entire base plate to move. The battery is inserted into the battery compartment. The movement of the base plate causes the two battery compartments on both sides to connect, causing the two ends of the battery to enter the two battery compartments respectively. The positive and negative terminals of the battery are connected to the detection line and the information is transmitted to the inside of the detection block through the sensing block.

[0015] In this invention, the motor is started, and the output shaft of the motor drives the motor threaded rod to rotate, causing the nut block to move on the outer surface of the motor threaded rod. The movement of the nut block drives the support bar to move. The operator manually pulls the telescopic cable to insert the detection head into the detection block for testing. The condition of the battery is determined by observing the detection light. If the battery is damaged, the damaged battery can be located by using the sensor light. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, such as Figure 1-4As shown, to achieve the above objectives, the present invention adopts the following technical solution: a power battery testing device, comprising: a base 1, a rotating shaft 101 movably connected to the top of the base 1, a turntable 102 sleeved on the outer surface of the rotating shaft 101, two fixing blocks 103 fixedly connected to both sides of the turntable 102, a linkage shaft 104 sleeved on the outer surface of the two fixing blocks 103, a fixing block 105 fixedly connected to the other side of each of the two linkage shafts 104, a connecting strip 106 fixedly connected to the top of each of the two fixing blocks 105, and a connecting strip 106 fixedly connected to both sides of each of the two connecting strips 106. A slider 107 is fixedly connected to the base 1. Multiple fixing strips 108 are fixedly installed on the top of the base 1. Sliding grooves 109 are opened on both sides of the multiple fixing strips 108. Multiple sliders 107 are slidably connected to the outer surface of the multiple fixing strips 108. An electric push rod 110 is fixedly installed on the top of the base 1. The output end of the electric push rod 110 is fixedly connected to a push plate 111. The push plate 111 is fixedly connected to the outer surface of one side of one of the sliders 107. The tops of the two connecting strips 106 are fixedly connected to a base plate 112. The tops of the two base plates 112 are fixedly installed with a fixing frame 114.

[0025] In this embodiment, the electric push rod 110 is activated, and the output end of the electric push rod 110 drives the push plate 111 to move. The movement of the push plate 111 causes the slider 107 to slide on the outer surface of the sliding groove 109. The sliding of the slider 107 causes the connecting bar 106 to move synchronously. Since the two linkage shafts 104 are connected to the fixed block 103 on the outer surface of the turntable 102, the movement of the connecting bar 106 causes the turntable 102 to rotate on the outer surface of the rotating shaft 101. However, since the turntable 102 is limited by the angle of the linkage shaft 104, the rotation angle of the turntable 102 is limited to 180 degrees. The rotation of the turntable 102 causes the two linkage shafts 104 to move in opposite directions. Therefore, the two connecting bars 106 move synchronously in opposite directions. The movement of the connecting bars 106 causes the entire base plate 112 to move.

[0026] Example 2, as Figure 1-4 As shown, a cylindrical frame 118 is fixedly installed on one side of the base 1, and a motor 119 is fixedly installed on the top of the cylindrical frame 118. The output shaft of the motor 119 is fixedly connected to a motor threaded rod 120. A nut block 121 is movably sleeved on the outer surface of the motor threaded rod 120. A support bar 122 is fixedly connected to one side of the nut block 121. Two telescopic lines 123 are fixedly connected to both sides of the support bar 122. A detection head 124 is fixedly installed on the other side of each of the two telescopic lines 123. Two detection lights 125 are fixedly installed on the top of each support bar 122.

[0027] In this embodiment, the motor 119 is started, and the output shaft of the motor 119 drives the motor threaded rod 120 to rotate, causing the nut block 121 to move on the outer surface of the motor threaded rod 120. The movement of the nut block 121 drives the support bar 122 to move. The operator manually pulls the telescopic cable 123 to insert the detection head 124 into the detection block 126 for detection. The battery condition is determined by observing the detection light 125. If the battery is damaged, the damaged battery is located by using the sensor light 127.

[0028] Working Principle: This device is a power battery testing device. During use, the electric push rod 110 is activated. The output end of the electric push rod 110 drives the push plate 111 to move. The movement of the push plate 111 causes the slider 107 to slide on the outer surface of the sliding groove 109. The sliding of the slider 107 causes the connecting strip 106 to move synchronously. Since the two linkage shafts 104 are connected to the fixed block 103 on the outer surface of the turntable 102, the movement of the connecting strip 106 causes the turntable 102 to rotate on the outer surface of the rotating shaft 101. However, due to the angle limitation of the linkage shafts 104, the rotation angle of the turntable 102 is limited to 180 degrees. The rotation of the turntable 102 causes the two linkage shafts 104 to move in opposite directions, so the two connecting strips 106 move synchronously in opposite directions. The movement of the connecting strips 106 drives the base plate 112. The entire unit is moved, and the battery is inserted into one of the battery tubes 115. As the base plate 112 moves, the two battery tubes 115 on both sides are connected, causing the two ends of the battery to be inserted into the two battery tubes 115 respectively. The positive and negative terminals of the battery are connected to the detection line 116 and the information is transmitted to the detection block 126 through the sensor block 117. Then, the motor 119 is started. The output shaft of the motor 119 drives the motor threaded rod 120 to rotate, causing the nut block 121 to move on the outer surface of the motor threaded rod 120. The movement of the nut block 121 drives the support bar 122 to move. The operator manually pulls the telescopic line 123 to insert the detection head 124 into the detection block 126 for detection. The battery condition is judged by observing the detection light 125. If the battery is damaged, the damaged battery is located by using the sensor light 127.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
