[0022] The utility model is further described below in conjunction with embodiments.

[0023] Example

[0024] The three-dimensional magnetic field testing device for the Hall element described in this embodiment is shown in the attached Figure 1 -Attached Figure 4 As shown, the outer frame 1 is made into a long strip shape as a whole, and frame walls are formed at both left and right ends of the outer frame 1. A rotating shaft 11 is respectively provided on the left and right frame walls of the outer frame 1. The rotating frame 3 is also in a long strip shape as a whole, but its height and length are slightly smaller than the height and length of the outer frame 1, so as to ensure that when the rotating frame 3 is set inside the outer frame 1 through the rotating shaft 11, a gap can be formed between the bottom of the rotating frame 3 and the bottom of the outer frame 1. For the convenience of installation, in this embodiment, a fixing groove 6 is respectively provided on the left and right outer side walls of the rotating frame 3, and the position and aperture of the fixing groove 6 correspond to the position and aperture of the rotating shaft 11, so as to ensure that the rotating shaft 11 can be fixed inside the fixing groove 6 in a plug-in manner, so that the rotating frame 3 can rotate synchronously with the rotating shaft 11.

[0025] An external motor 2 is fixed at an external position at one end of the outer frame 1, that is, the external motor 2 can be arbitrarily arranged on the left or right side of the outer frame 1. An external driven tooth 12 is arranged at the end of the rotating shaft 11 located on one side of the external motor 2, that is, the external driven tooth 12 and the external motor 2 are located on the same side of the outer frame 1, so as to ensure that the external driven tooth 12 and the external motor 2 can be connected by a belt or a gear, that is, the driving force of the external motor 2 can be transmitted to the external driven tooth 12 through the belt or the gear.

[0026] A long slot is provided in the middle of the rotating frame 3, and an internal motor 4 is arranged inside the rotating frame 3. The bottom end of the internal motor 4 passes through the slot through a bolt, and engages with the bottom of the fixing bolt through a locking nut to achieve fixed connection with the rotating frame 3. The rotating shaft of the internal motor 4 extends vertically downward and passes through the bottom of the rotating frame 3 and is located inside the gap. At the same time, an internal driving wheel 41 is provided on the rotating shaft of the internal motor 4, and the internal driving wheel 41 is also located inside the gap.

[0027] In order to facilitate the testing of the Hall element, a fixing assembly 5 is provided in the middle of the rotating frame 3, and the fixing assembly 5 is composed of a rotating table 51 and a bottom driven tooth 52 fixed to the bottom end of the rotating table 51. The rotating table 51 is arranged in the middle of the rotating frame 3, and the bottom driven tooth 52 is located inside the gap, and the bottom driven tooth 52 is fixedly connected to the bottom of the rotating table 51 to ensure that the rotating table 51 and the bottom driven tooth 52 can rotate synchronously in a clockwise or counterclockwise direction around the central axis of the rotating table 51. A number of preset holes 7 are provided in the middle of the rotating table 51 for mounting and fixing the Hall element to be tested.

[0028] At this time, the inner driving wheel 41 and the bottom driven gear 52 are both located in the gap formed by the bottom of the outer frame 1 and the bottom of the rotating frame 3. Similarly, the inner driving wheel 41 and the bottom driven gear 52 can also be connected by a belt or gear to ensure that the driving force of the internal motor 4 can drive the rotating table 51 to rotate clockwise or counterclockwise.

[0029] In order to reduce the overall height of the device, the height of the gap only needs to be such that when the entire rotating frame 3 rotates on a vertical plane, the bottom driven teeth 52 and the inner driving wheel 41 will not come into contact with the bottom of the outer frame 1.

[0030] In order to facilitate the installation of the entire testing device, connecting plates 13 with through holes are fixedly provided at the four outer corners of the outer frame 1 .

[0031] This embodiment, through the framework structure of the outer frame 1, the rotating shaft 11, the rotating frame 3 and the rotating platform 51 and their mutual cooperation, can transmit the power of the external motor 2 to the external driven gear 12 through a belt or a gear, and then transmit its power to the rotating shaft 11 through the rotation of the external driven gear 12, and finally drive the rotating frame 3 to rotate left and right in the vertical plane under the action of the rotating shaft 11; at the same time, the rotating platform 51 can rotate clockwise or counterclockwise in the horizontal plane under the drive of the internal motor 4. Finally, the rotation on the vertical plane and the horizontal plane is realized, and the test efficiency is improved.

[0032] As described above, the present utility model can be realized better.
