Description

Technical Field

[0001] The utility model relates to the technical field of waste power battery detection devices, and in particular to a retired power battery residual energy detection machine. Background Art

[0002] With the global concern about reducing greenhouse gas emissions and air pollution, the market demand for new energy vehicles, especially electric vehicles, is growing rapidly. As the core component of electric vehicles, the performance and safety testing of power batteries has become particularly important. The performance of power batteries is directly related to the endurance and safety of electric vehicles. Battery residual energy testing machines can evaluate the health of batteries, prevent battery performance degradation and potential safety risks, and are of great significance for enhancing user confidence and promoting new energy vehicles. As a large number of electric vehicles are put into use, the problem of battery retirement and recycling will be faced in the future. Battery residual energy testing machines can accurately evaluate retired batteries and provide data support for battery recycling, reuse or remanufacturing, which is in line with the requirements of circular economy and sustainable development.

[0003] In the prior art, the lines in the power battery remaining energy detection device are long and complicated, which makes it easy for workstation accidents to occur. The long lines will be dragged on the ground or hung in the air in the working area, which will cause the workers to trip or be entangled in the lines, causing falls. Frequent movement and operation will cause physical damage to the lines, such as wear, indentation or cutting, which will lead to electrical failure or short circuit. The lines are dragged or hung in the working area and are easily crushed by heavy objects or damaged by tools, causing the insulation layer to wear, the wires to be exposed, or even broken. These physical damages cause electrical short circuits, open circuits or unstable connections, affecting the normal operation of the detection device. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a retired power battery residual energy detection machine.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a detection platform, a wire-taking device is fixed on the upper end surface of the detection platform, the wire-taking device includes the outer wall of a box body, the inner wall of the outer wall of the box body is fixed with a support shaft, the outer wall of the support shaft is rotatably connected with a wire winder, the upper end surface of the wire winder is provided with an annular groove, the inside of the annular groove is fixed with oblique square teeth, the bottom of the wire winder is fixed with a rotary spring, the other end of the rotary spring is fixedly connected to the outer wall of the box body, a detection wire is wound around the circumference of the wire winder, one end of the detection wire is electrically connected to a detection display, and the other end of the detection wire is electrically connected to a detection display. A detection pen is connected to the box body, a fixed shell is fixed on the upper end face of the outer wall of the box body, a positioning shaft is fixed on the inner wall of the fixed shell, a connecting plate is contacted on the surface of the positioning shaft, a supporting spring is fixed on the inner wall of the fixed shell, the upper end face of the supporting spring is fixedly connected to the connecting plate, the upper end face of the connecting plate is fixed to the switch button, a fixing pin is fixed on the bottom end face of the connecting plate, and the bottom of the fixing pin is slidably connected to the annular groove. In the prior art, the circuits in the power battery residual energy detection device are long and complicated, which makes it easy to cause workstation accidents. The long circuits will be dragged on the ground or hung in the air in the working area, which leads to Workers trip or get entangled in wires, causing falls. Frequent movement and operation can cause physical damage to wires, such as wear, indentation or cutting, which leads to electrical failure or short circuit. Lines are dragged or hung in the work area and are easily crushed by heavy objects or damaged by tools, causing insulation wear, wire exposure, or even breakage. These physical damages cause electrical short circuits, disconnections, or unstable connections, affecting the normal operation of the detection device. By installing a wire take-up device, when the user uses the detection device, the detection pen drives the detection wire to be pulled out. At this time, the detection wire is entangled on the wire winder, causing the wire winder to rotate. , so the fixing pin rotates clockwise along the annular groove. After the length required by the user is pulled out, the wire winder rotates with the help of the return spring. At this time, the fixing pin is blocked by the bevel teeth inside the annular groove, so the wire winder cannot continue to rotate. Therefore, the detection line pulled out by the user is fixed. After the detection is completed, the user presses the switch button. At this time, with the help of the connecting plate, the fixing pin is lifted. Therefore, the wire winder is reset with the help of the return spring, thereby retracting the detection line, thereby avoiding the problem of workstation accidents caused by the long and complicated wires of the detection device.

[0006] Preferably, a fixing device and a handle are provided inside the detection platform, the fixing device includes a fixing base, the fixing base is fixedly connected to the detection platform, an adjusting spring is fixed to the upper end surface of the fixing base, an expansion clamping tooth is fixed to the top of the adjusting spring, an axial rod is fixed to the bottom of the handle, a frustum is fixed to the bottom of the axial rod, and the frustum and the expansion clamping tooth are detachably connected. In the prior art, power batteries are often fixed to the platform of the power battery detection device by bolts. Using bolts to fix the battery usually requires a certain amount of installation time, including steps such as alignment, tightening or loosening bolts, and these operations are relatively time-consuming, especially when the battery needs to be frequently replaced for testing. For heavy batteries, For large or oversized power batteries, manual tightening and loosening of bolts requires great physical strength, which increases the labor intensity of the staff. Various tools, such as wrenches, are required for bolt fixing. If used improperly, it may cause equipment damage or personal injury. The utility model adopts a new fixing device. The user places the power battery on the surface of the operating platform, removes the handle, and then aligns the holes and grooves around the power battery with the expansion teeth to install the power battery. Then, the handle is installed and the handle is pressed to make the cone downward. Then, the expansion teeth expand outward along the cone until the power battery is buckled and fixed, thereby increasing the installation efficiency of the power battery and increasing the detection speed of the user.

[0007] Preferably, the support spring is a double-strand spring. The design of the double-strand spring makes it more stable than a single-strand spring when bearing load, because the two spiral coils can support each other, reducing distortion and deflection, thereby increasing the stability of the spring mechanism and improving the service life of the device.

[0008] Preferably, a buffer washer is fixed to the tail end of the detection pen, so as to buffer the collision between the detection pen and the outer wall of the box body when the wire winder is quickly reset, thereby avoiding damage to the detection pen.

[0009] Preferably, baffles are fixed at both ends of the wire winder to prevent the detection wire from falling off the wire winder when the wire winder is reset.

[0010] Preferably, the surface of the handle is covered with a rubber sleeve, which usually has a soft touch and good elasticity, can improve the comfort of the handle and reduce hand fatigue during long-term use, thereby avoiding hand fatigue caused by frequent plugging and unplugging of users, resulting in reduced detection work efficiency.

[0011] Preferably, a latch tooth is provided inside the expansion latch tooth, thereby further improving the tightness between the frustum and the expansion latch tooth.

[0012] Beneficial Effects

[0013] 1. In the prior art, the circuits in the power battery residual energy detection device are long and complicated, which makes it easy for workstation accidents to occur. The long circuits will be dragged on the ground or hung in the air in the working area, which will cause the workers to trip or be entangled in the circuits, causing falls. Frequent movement and operation will cause physical damage to the circuits, such as wear, indentation or cutting, which will cause electrical failures or short circuits. The circuits are dragged or hung in the working area, which are easily crushed by heavy objects or damaged by tools, causing the insulation layer to wear, the wires to be exposed, or even broken. These physical damages cause electrical short circuits, circuit breaks or unstable connections, affecting the normal operation of the detection device. By installing a wire-retracting device, the user can put the detection pen in the detection device when using the detection device. The detection line is driven to be pulled out. At this time, since the detection line is wound on the winder, the winder rotates, so the fixing pin rotates clockwise along the annular groove. After the required length of the user is pulled out, the winder rotates with the help of the return spring. At this time, the fixing pin is blocked by the bevel teeth inside the annular groove, so the winder cannot continue to rotate. Therefore, the detection line pulled out by the user is fixed. After the detection is completed, the user presses the switch button. At this time, with the help of the connecting plate, the fixing pin is lifted. Therefore, the winder is reset with the help of the return spring, thereby retracting the detection line, thereby avoiding the problem of work station accidents caused by the long and complicated wires of the detection device.

[0014] 2. In the prior art, power batteries are often fixed on the platform of the power battery detection device by bolts. Fixing the battery with bolts usually requires a certain amount of installation time, including steps such as alignment, tightening or loosening the bolts, etc. These operations are time-consuming, especially when the battery needs to be frequently replaced for testing. For power batteries with heavy weight or large size, manual tightening and loosening of the bolts will require greater physical strength, increasing the labor intensity of the staff. Bolt fixing requires the use of various tools, such as wrenches, etc. If used improperly, it will cause equipment damage or personal injury. The utility model adopts a new type of fixing device. The user places the power battery on the surface of the operating platform, removes the handle, and then aligns the holes and grooves around the power battery with the expansion teeth to install the power battery, then installs the handle, presses the handle to make the cone downward, and then the expansion teeth expand outward along the cone until the power battery is buckled and fixed, thereby increasing the installation efficiency of the power battery and increasing the detection speed of the user.

[0025] In the prior art, the lines in the power battery residual energy detection device are long and complicated, which makes it easy for workstation accidents to occur. The long lines will be dragged on the ground or hung in the air in the work area, which will cause the workers to trip or be entangled in the lines, causing falls. Frequent movement and operation will cause physical damage to the lines, such as wear, indentation or cutting, which will cause electrical failure or short circuit. The lines are dragged or hung in the work area and are easily crushed by heavy objects or damaged by tools, causing the insulation layer to wear, the wires to be exposed, or even broken. These physical damages cause electrical short circuits, disconnections or unstable connections, affecting the normal operation of the detection device. By installing the wire take-up device 2, when the user uses the detection device, the detection pen drives the detection line 207 to be pulled out. At this time, since the detection line 207 is entangled in the wire winder 20 3, the wire winder 203 rotates, so the fixing pin 213 rotates clockwise along the annular groove 204. After the length required by the user is pulled out, the wire winder 203 rotates with the help of the return spring 206. At this time, the fixing pin 213 is blocked by the bevel teeth 205 inside the annular groove 204, so the wire winder 203 cannot continue to rotate, so the detection line 207 pulled out by the user is fixed. After the detection is completed, the user presses the switch button 212. At this time, with the help of the connecting plate 211, the fixing pin 213 is lifted, so the wire winder 203 is reset with the help of the return spring 206, so that the detection line 207 is retracted, thereby avoiding the problem of workstation accidents caused by the long and complicated wires of the detection device.

[0026] The working principle of the utility model is as follows: when the user uses the detection device, the user drives the detection pen to pull out the detection line 207. At this time, since the detection line 207 is wound on the winder 203, the winder 203 rotates, so the fixing pin 213 rotates clockwise along the annular groove 204. After the required length of the user is pulled out, the winder 203 rotates with the help of the return spring 206. At this time, the fixing pin 213 is blocked by the bevel teeth 205 inside the annular groove 204, so the winder 203 cannot continue to rotate. Therefore, the detection line 207 pulled out by the user is fixed. After the detection is completed, the user presses the switch button 212. At this time, with the help of the connecting plate 211, the fixing pin 213 is lifted up. Therefore, the winder 203 is reset with the help of the return spring 206, thereby retracting the detection line 207.
