Description

Technical Field

[0001] This utility model relates to the field of dynamometer technology, specifically a miniature portable high-precision dynamometer. Background Technology

[0002] A dynamometer is used to measure key performance parameters of an electric motor, such as power, torque, and speed. It is an important tool for evaluating the efficiency and performance of an electric motor. By simulating the load conditions under which the electric motor is actually working, it accurately measures the output capacity of the motor, providing strong support for the research, development, production, and maintenance of electric motors.

[0003] Existing dynamometers for measuring electric motors typically have their brakes, sensors, clamps, and motors arranged in a straight line. This not only occupies a lot of space, but also makes transportation and installation particularly cumbersome when on-site testing or use in different locations. For users who need to frequently test electric motor performance or work in different environments, this inconvenience greatly reduces work efficiency and flexibility. Therefore, we propose a miniature portable high-precision dynamometer. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that the existing dynamometers for measuring electric motors have brakes, sensors, clamps, and motors arranged in a straight line, which takes up a lot of space and is not convenient to carry and transport.

[0005] To address the aforementioned technical problems, this application provides a miniature portable high-precision dynamometer, including a base, and further comprising:

[0006] A rotating unit is provided on the top of the base. The rotating unit contains a first plate and a second plate. The second plate is rotatably connected to the first plate. The second plate drives the clamp to rotate, thereby reducing the space occupied.

[0007] The measuring unit is located on the top of the base. The measuring unit contains a brake, a sensor, and a clamp. The brake, sensor, and clamp work together to measure values.

[0008] In some embodiments, the rotating unit includes a first rotating member disposed on the top of the base, and a second rotating member disposed on the top of the first rotating member. The first rotating member and the second rotating member cooperate to reduce the space occupied.

[0009] In some embodiments, the first rotating member includes a first plate disposed on the top of the base, the top of the first plate having a circular groove, a motor disposed on the inner top of the first plate, a drive gear disposed on the drive end of the motor, and a first limiting block disposed on the top of the first plate.

[0010] In some embodiments, an arc-shaped groove is provided in the first limiting block, and the arc-shaped groove is connected to the circular groove.

[0011] In some embodiments, the second rotating member includes a second plate disposed on the top of the first plate, a semi-circular toothed plate disposed at the bottom of the second plate, the semi-circular toothed plate meshing with a drive gear, a second limiting block disposed at the bottom of the second plate, a rotating shaft disposed at the bottom of the second plate, the bottom end of the rotating shaft being rotatably connected to the first plate, and a rotating plate being rotatably connected to the top of the second plate.

[0012] In some embodiments, a limiting strip is provided at the bottom of the semi-circular toothed plate, and the limiting strip is rotatably connected in the circular groove.

[0013] In some embodiments, the measuring unit includes a brake disposed on the top of a first plate, a sensor disposed on one side of the brake, the sensor being welded to the top of a rotating plate, a clamp disposed on one side of the sensor, the bottom of the clamp being fixedly welded to a second plate, a first coupling rod disposed between the brake and the sensor, and a second coupling rod disposed on one side of the sensor.

[0014] In some embodiments, two rods are rotatably connected within the second plate, each rod having a screw threadedly connected to it, each screw having a wheel welded to its top, and each screw having a support block at its bottom.

[0015] This utility model has at least the following beneficial effects:

[0016] By setting a rotating unit, the second rotating component rotates on top of the first rotating component and stops rotating when it reaches 90 degrees. At this time, the fixture will rotate to 90 degrees with the second rotating component. The brake, sensor and fixture are changed from a linear layout to a vertical layout, which significantly reduces the area occupied. In short, it can reduce the space occupied and make it easier to carry, transport and install.

[0017] Meanwhile, the sensor does not rotate with the rotation of the second plate, so there is no need to disassemble the second coupling. Only the object to be measured needs to be separated from the first coupling, reducing the number of operation steps. Attached Figure Description

[0024] 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. Example 1

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A miniature portable high-precision dynamometer includes a base 1, a rotating unit 2, and a measuring unit 3. The rotating unit 2 is located on the top of the base 1 and contains a first plate 211 and a second plate 221. The second plate 221 is rotatably connected to the first plate 211 and drives a clamp 33 to rotate, thereby reducing space occupation. The measuring unit 3 is located on the top of the base 1 and contains a brake 31, a sensor 32, and a clamp 33. The brake 31, sensor 32, and clamp 33 work together to measure values.

[0027] The rotating unit 2 includes a first rotating member 21 disposed on the top of the base 1, and a second rotating member 22 disposed on the top of the first rotating member 21. The first rotating member 21 and the second rotating member 22 cooperate to reduce the space occupied. The central axis of the first rotating member 21 and the second rotating member 22 is set as a rotating shaft 224, which rotates the unit.

[0028] The first rotating component 21 includes a first plate 211 disposed on the top of the base 1. A circular groove 212 is provided on the top of the first plate 211. A motor 213 is disposed on the inner top of the first plate 211. A drive gear 214 is disposed on the drive end of the motor 213. A first limiting block 215 is disposed on the top of the first plate 211. An arc-shaped groove 216 is provided in the first limiting block 215. The arc-shaped groove 216 communicates with the circular groove 212. The semi-circular toothed plate 222 can rotate into the arc-shaped groove 216 so as not to obstruct its rotation.

[0029] The second rotating component 22 includes a second plate 221 disposed on the top of the first plate 211. A semi-circular toothed plate 222 is disposed at the bottom of the second plate 221, which meshes with the drive gear 214. A second limiting block 223 is disposed at the bottom of the second plate 221. A rotating shaft 224 is disposed at the bottom of the second plate 221, and the bottom end of the rotating shaft 224 is rotatably connected to the first plate 211. A rotating plate 225 is rotatably connected to the top of the second plate 221. A limiting strip 226 is disposed at the bottom of the semi-circular toothed plate 222, which is rotatably connected in the circular groove 212. The limiting strip 226 is used to limit the rotation and prevent it from deviating from the center. In addition, the abutment between the first limiting block 215 and the second limiting block 223 can stop the rotation, so that the first plate 211 and the second plate 221 stop rotating when they reach a parallel state.

[0030] When in use, the motor 213 is started, which drives the drive gear 214 to rotate, which in turn drives the semi-circular toothed plate 222 to rotate. The semi-circular toothed plate 222 then drives the second rotating component 22 to rotate as a whole. When it rotates to 90 degrees, it stops rotating. At this time, the clamp 33 will rotate to 90 degrees with the second rotating component 22. The brake 31, sensor 32 and clamp 33 change from a linear layout to a vertical layout, which can reduce the space occupied and make it easier to carry. At the same time, since the bottom of the sensor 32 is welded to the rotating plate 225, and the rotating plate 225 is rotatably connected to the second plate 221, and the sensor 32 is connected to the brake 31 through the first coupling rod 34, the sensor 32 will not rotate. Therefore, it is not necessary to disassemble the second coupling rod 35. Only the object to be measured and the first coupling rod 34 need to be disassembled, reducing the operation steps.

[0031] Furthermore, two rods 4 are rotatably connected inside the second plate 221. Each rod 4 is threaded with a screw 41. A rotating wheel 42 is welded to the top of each screw 41, and a support block 43 is provided at the bottom of each screw 41. When the first plate 211 and the second plate 221 are rotated to a straight layout, the two rods 4 can be rotated to a state perpendicular to the ground. Then, the rotating wheel 42 is rotated to drive the screw 41 to rotate and descend, which in turn drives the support block 43 to descend and press against the ground to support the second plate 221. This enhances stability. Example 2

[0032] Please see Figure 1 This utility model provides a technical solution:

[0033] Unlike Embodiment 1, the measuring unit 3 includes a brake 31 disposed on the top of the first plate 211, a sensor 32 disposed on one side of the brake 31, the sensor 32 being welded to the top of the rotating plate 225, a clamp 33 disposed on one side of the sensor 32, the bottom of the clamp 33 being fixedly welded to the second plate 221, a first coupling rod 34 disposed between the brake 31 and the sensor 32, and a second coupling rod 35 disposed on one side of the sensor 32. The brake 31 is used for braking, the sensor 32 is used for actual measurement, the clamp 33 is used for clamping and fixing the object to be measured, and the first coupling rod 34 and the second coupling rod 35 are used for connection. The brake 31, the sensor 32 and the clamp 33 are existing technologies and will not be described in detail here.

[0034] After the object to be tested is clamped by the fixture 33, the drive end of the object to be tested is connected to the sensor 32 through the second coupling 35. When the object to be tested is started, the sensor 32 measures the power and speed, and the brake 31 performs braking.
