Description

Technical Field

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

[0002] A battery tester is an electronic device used for real-time monitoring and management of batteries. It can measure parameters such as voltage, internal resistance, and capacity. It is easy to operate, versatile, and can accurately assess battery status, ensuring normal equipment operation. Currently, battery testers are often used in conjunction with testing fixtures to achieve modular, batch testing capabilities.

[0003] Currently, a Chinese patent discloses a batch testing fixture for lithium batteries (authorization announcement number CN222125399U). A motor is placed on the upper surface of the support plate, and a drive sprocket is installed at the output end of the motor. A connecting rod is fixedly connected to the bottom surface of each turntable, and a driven sprocket is fixedly connected to the other end of each connecting rod. The drive sprocket and the driven sprocket are connected by chain drive, which is beneficial to the stability of the drive sprocket and the driven sprocket. The rotation of the drive sprocket can drive the driven sprocket to rotate stably.

[0004] As can be seen from the above reference case, the above device uses a chain to drive multiple sprockets on the same straight line to rotate simultaneously. However, since the above device also uses an elastic structure to lock batteries of different diameters, when the elastic structure comes into contact with the battery in advance, the elastic structure will hinder the sprocket transmission. This will increase the resistance of the chain drive sprocket. Furthermore, there is no obstruction on the chain surface. At this time, the chain is prone to "tooth skipping" due to excessive resistance, causing the sprocket rotation to become unbalanced. Consequently, the transmission of the sprocket loses uniformity, making it difficult to ensure that the clamping fixture is uniformly reset by the chain in the future.

[0005] Therefore, a modular battery state monitoring device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a modular battery status monitoring device to solve the above-mentioned problems, thereby improving the problem of unstable clamping and adjustment of the existing modular battery status monitoring device using synchronous centering fixture.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a modular battery status monitoring device, comprising: a mounting frame and an adjustment mechanism, wherein uniformly distributed lower conductive sheets are embedded in the surface of the mounting frame, an elastic guide mechanism is fixedly connected to the surface of the mounting frame, and uniformly distributed upper conductive sheets, each opposite to an adjacent lower conductive sheet, are fixedly connected to the surface of the elastic guide mechanism.

[0008] Preferably, the adjustment mechanism includes a horizontal electric cylinder fixedly connected inside the mounting frame, a crossbar fixedly connected to the end of the output shaft of the horizontal electric cylinder, a uniformly distributed rack fixedly connected to one end of the crossbar, a gear rotatably connected to the mounting frame meshing with the surface of the rack, a central clamping assembly slidably connected to the top of the gear, and a lower conductive sheet disposed inside the central clamping assembly.

[0009] Preferably, the mounting frame has an internal mounting cavity, the horizontal electric cylinder is fixedly connected to the inside of the mounting cavity, the crossbar is slidably connected to the inside of the mounting cavity, the gear and the centering clamping assembly are rotatably connected to the inside of the mounting cavity, and the top of the centering clamping assembly extends through to the outside of the mounting cavity.

[0010] Preferably, the maximum stroke of the horizontal electric cylinder driving the crossbar to reciprocate is the same as the stroke of the rack driving the gear to rotate ±90°.

[0011] Preferably, the mounting bracket has a guide cavity that communicates with the mounting cavity, and the crossbar is slidably connected to the inside of the guide cavity.

[0012] Preferably, the lower conductive sheet, rack, gear, and centering clamping assembly are all used in combination and are all the same quantity.

[0013] Preferably, a bearing is fixedly connected to the bottom of the gear, and the bearing is embedded in the interior of the mounting cavity.

[0014] Preferably, a controller is fixedly connected to one end of the mounting bracket, and the controller is electrically connected to the horizontal electric cylinder.

[0015] The beneficial effects of this utility model are:

[0016] 1. The testing personnel only need to control the horizontal electric cylinder to move in the corresponding direction through the controller. The horizontal electric cylinder drives the crossbar, rack and pinion, and the gear to deform all the centering clamping components, so that the centering clamping components clamp or release the battery in the center. Compared with the existing chain and sprocket drive design of all centering clamping components, this can effectively reduce the probability of slippage of the centering clamping components during the adjustment process, so that all the centering clamping components can operate stably and synchronously. This not only ensures the stability of battery status testing, but also reduces the probability of subsequent maintenance by the testing personnel.

[0017] 2. The design of housing the crossbar, rack, and gear inside the mounting cavity isolates them from the outside environment, allowing them to operate in a clean environment and reducing resistance in horizontal transmission. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-4 As shown, a modular battery status monitoring device includes: a mounting frame 100 and an adjustment mechanism 500. The surface of the mounting frame 100 is embedded with uniformly distributed lower conductive sheets 200. The surface of the mounting frame 100 is fixedly connected to an elastic guide mechanism 300. The surface of the elastic guide mechanism 300 is fixedly connected to uniformly distributed upper conductive sheets 400 that are respectively opposite to the adjacent lower conductive sheets 200.

[0025] The battery tester mainly consists of key components such as a control module, test circuit, measurement module, display unit, and interface and communication module. The control module is responsible for overall control and data processing. The test circuit simulates battery working conditions for charging and discharging. The measurement module accurately collects parameters such as battery voltage, current, and temperature. The display unit shows the test results. The interface and communication module realizes data transmission with external devices and connection with the lower conductive plate 200 and upper conductive plate 400. The battery tester operates based on the charging and discharging characteristics of the battery. The user first sets the test parameters according to the battery type. Then, the battery tester charges the battery according to the set parameters until it is fully charged. Next, a discharge test is performed to simulate the load conditions in actual use and records the changes in various battery parameters. After the test is completed, the tester processes and analyzes the collected data, evaluates the battery's performance and health status, and displays the results in the form of charts, reports, etc. Throughout the testing process, the tester also has a safety protection mechanism to ensure the safety and reliability of the testing process.

[0026] Before use, the lower conductive plate 200 and the upper conductive plate 400 are connected to the corresponding interfaces of the battery tester via connector wires. Once the battery establishes a connection between the lower conductive plate 200 and the upper conductive plate 400, the battery tester establishes a connection with the battery via connector wires, the lower conductive plate 200, and the upper conductive plate 400.

[0027] The elastic guide mechanism 300 includes a vertical electric cylinder fixedly connected to the surface of the mounting bracket 100. A horizontal plate is fixedly connected to the end of the output shaft of the vertical electric cylinder. T-shaped guide rods are evenly distributed and inserted into the top of the horizontal plate. The bottom of the T-shaped guide rods extends through to the bottom of the horizontal plate. The bottom of the T-shaped guide rods is fixedly connected to the upper conductive plate 400. A plastic spring is sleeved on the surface of the T-shaped guide rods. The plastic spring is located between the horizontal plate and the upper conductive plate 400.

[0028] Once the battery is centered and clamped, the user only needs to manually control the vertical electric cylinder to retract. The vertical electric cylinder drives the horizontal plate to move down, the horizontal plate drives all the T-shaped guide rods to move down, and the T-shaped guide rods drive the upper conductive plates 400 to move down until all the upper conductive plates 400 are in contact with the corresponding positive or negative terminal of the battery.

[0029] like Figure 1-4As shown, the adjustment mechanism 500 includes a horizontal electric cylinder 510 fixedly connected inside the mounting bracket 100. A crossbar 520 is fixedly connected to the end of the output shaft of the horizontal electric cylinder 510. A uniformly distributed rack 530 is fixedly connected to one end of the crossbar 520. A gear 540 rotatably connected to the mounting bracket 100 is meshed with the surface of the rack 530. A centrally located clamping assembly 550 slidably connected to the mounting bracket 100 is fixedly connected to the top of the gear 540. The lower conductive sheet 200 is provided with... Inside the centering clamping assembly 550; the mounting bracket 100 has a mounting cavity 110, the horizontal electric cylinder 510 is fixedly connected to the inside of the mounting cavity 110, the crossbar 520 is slidably connected to the inside of the mounting cavity 110, the gear 540 and the centering clamping assembly 550 are both rotatably connected to the inside of the mounting cavity 110, and the top of the centering clamping assembly 550 extends to the outside of the mounting cavity 110, housing the crossbar 520, rack 530 and gear 540 within the mounting cavity 110. The design of the component isolates the crossbar 520, rack 530, and gear 540 from the outside environment, allowing them to operate in a clean environment and reducing resistance in horizontal transmission. The maximum stroke of the horizontal electric cylinder 510 driving the crossbar 520 to reciprocate is the same as the stroke of the rack 530 driving the gear 540 to rotate ±90°. The mounting bracket 100 has a guide cavity 120 communicating with the mounting cavity 110, and the crossbar 520 is slidably connected inside the guide cavity 120. The lower conductive plate 200, rack 530, gear 540, and centering clamping assembly 550 are all used in the same quantity. A bearing 560 is fixedly connected to the bottom of the gear 540 and is embedded inside the mounting cavity 110. A controller 600 is fixedly connected to one end of the mounting bracket 100, and the controller 600 is electrically connected to the horizontal electric cylinder 510. The specific connection method needs to be selected according to the actual situation and will not be described in detail here.

[0030] The surface of the mounting bracket 100 is provided with evenly distributed grooves that are arranged in a ring around the adjacent gears 540. The grooves are connected to the mounting cavity 110. The central clamping assembly 550 includes a turntable fixedly connected to the top of the gear 540. The surface of the turntable is hinged with a ring-shaped connecting rod. One end of the connecting rod is hinged to a slider that is slidably connected to the groove. The top of the slider is fixedly connected to an arc-shaped clamping plate. One end of the arc-shaped clamping plate is provided with a horizontal cavity. A horizontal guide rod is slidably connected inside the horizontal cavity. One end of the horizontal guide rod is fixedly connected to a reinforcing clamping plate. The other end of the horizontal guide rod is fixedly connected to a metal spring that contacts the horizontal cavity. The metal spring is always in a compressed state.

[0031] When gear 540 rotates, it drives the turntable to rotate, which in turn pulls all the connecting rods. The connecting rods drive the slider to move directionally inside the groove. The slider drives the arc-shaped clamping plate to move closer to or away from gear 540 until the battery is firmly clamped or reset. As the arc-shaped clamping plate moves closer to gear 540, it drives the reinforcing clamping plate closer to the battery through the horizontal cavity and the horizontal guide rod. When the reinforcing clamping plate contacts the battery in advance, the battery blocks the reinforcing clamping plate from moving forward. The reinforcing clamping plate, through the horizontal guide rod and the arc-shaped clamping plate, compresses the metal spring. At this time, the elasticity of the metal spring increases continuously, firmly and centrally locking the battery at the top of the lower conductive sheet 200.

[0032] When this invention is in use, if the testing personnel need to lock or unlock the battery simultaneously, they only need to control the horizontal electric cylinder 510 to move in the corresponding direction via the controller 600. The horizontal electric cylinder 510 drives the crossbar 520 to move, the crossbar 520 drives all the racks 530 to move, the racks 530 drive the gears 540 to rotate, and the gears 540 drive the centering clamping component 550 to deform, so that the centering clamping component 550 clamps or releases the battery in the center. Compared with the existing chain and sprocket drive design of all centering clamping components 550, this can effectively reduce the probability of slippage of the centering clamping component 550 during the adjustment process, so that all the centering clamping components 550 can operate stably and synchronously. This not only ensures the stable operation of battery status testing, but also reduces the probability of subsequent maintenance by the testing personnel.

[0033] It should be noted that the battery tester, lower conductive plate 200, vertical electric cylinder, upper conductive plate 400, horizontal electric cylinder 510, bearing 560, and controller 600 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the battery tester, vertical electric cylinder, horizontal electric cylinder 510, and controller 600 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
