[0028] Please refer to Figure 1 , this embodiment provides a mobile phone compass test device. The mobile phone compass test device includes a test platform 1, a graduated compass 2, a rotating bracket 3, and a mobile phone bracket 4. The graduated compass 2 is disposed on the test platform 1. The rotating bracket 3 is rotatably arranged on the test platform 1, and its rotation axis is perpendicular to the graduated compass 2. The rotating bracket 3 includes a pair of clamping arms 31 arranged oppositely. The mobile phone bracket 4 is rotatably arranged between the two clamping arms 31 and is suspended above the graduated compass 2.
[0029] Among them, since the mobile phone compass test is affected by the geomagnetic field during the test process, the test platform 1, the graduated compass 2, the rotating bracket 3, and the mobile phone bracket 4 are all made of plastic or ceramic materials, effectively reducing the influence of metal objects on the test process.
[0030] Please refer to together Figure 2, on one side of the two clamping arms 31, there is a "7"-shaped sliding rail 311. On both sides of the mobile phone holder 4, there are sliding rods 41. The sliding rods 41 are slidably connected to the sliding rail 311. The sliding rail 311 includes a connected lifting sliding rail 3111 and a translation sliding rail 3112. The translation sliding rail 3112 extends parallel to the scale compass 2 from one end of the lifting sliding rail 3111 away from the scale compass 2. The line connecting the closest end of the lifting sliding rail 3111 to the scale compass 2 and the farthest end of the translation sliding rail 3112 from the lifting sliding rail 3111 is perpendicular to the scale compass 2, and the line is located in the middle of the clamping arm 31. When the mobile phone needs to be tested vertically, the mobile phone holder 4 can be raised along the lifting sliding rail 3111 to the translation sliding rail 3112, so that the mobile phone holder 4 is away from the scale compass 2, leaving enough height for the mobile phone to be placed vertically. When the mobile phone needs to be tested horizontally, the mobile phone holder 4 can be moved from the translation sliding rail 3112 to the lowest end of the lifting sliding rail 3111, so that the mobile phone holder 4 is arranged parallel to the scale compass 2. Preferably, the sliding rod 41 is of a cylindrical structure, which facilitates the mobile phone holder 4 to rotate to any angle.
[0031] The test platform 1 is of a disc-shaped structure. Adopting this structure can avoid problems such as sharp corners or edges in a square structure that may cause harm to testers, and improve the safety factor. In order to further improve the test accuracy, the test platform 1 is arranged parallel to the horizontal plane.
[0032] Please refer to Figure 3 , the test platform 1 is provided with an annular groove 11. The same ends of the two clamping arms 31 are connected by an arc-shaped sliding arm 32. The sliding arms 32 are oppositely arranged at both ends of the clamping arms 31. The bottom of the sliding arm 32 is inserted into the annular groove 11. The sliding arm 32 slides annularly in the annular groove 11, driving the clamping arm 31 to rotate 360 degrees in the horizontal direction to determine the compass accuracy in different orientations. By using the mobile phone holder 4 to cooperate with the sliding of the sliding arm 32 in the annular groove 11, the accuracy tests in the three directions of the x, y, and z axes of the mobile phone gyroscope can be covered. In addition, the sliding fit between the annular groove 11 and the sliding arm 32 can also make the rotation of the clamping arm 31 more stable, further improving the test accuracy. In another embodiment, a rotating shaft is provided in the middle of the test platform 1, and the middle parts of the two clamping arms 31 are connected by a connecting arm. The connecting arm is provided with a through hole matching the rotating shaft.
[0033] Please refer to Figure 4 and Figure 5, the mobile phone compass testing device further includes a ball 5. A groove 321 is provided at the bottom of the sliding arm 32. The depth of the groove 321 is less than the diameter of the ball 5. The ball 5 is arranged between the annular groove 11 and the groove 321. The friction between the sliding arm 32 and the annular groove 11 is reduced, and the smoothness of the rotation of the rotating bracket 3 is improved. Specifically, two grooves 321 are provided at the bottom of a single sliding arm 32, which are matched with the two balls 5 to improve the rotation stability. In another embodiment, three, four or other numbers of grooves 321 may be provided at the bottom of a single sliding arm 32. Correspondingly, the number of balls 5 is matched with it. In another embodiment, lubricating oil is applied in the annular groove 11, which can also improve the smoothness of the rotation of the rotating bracket 3.
[0034] The slide rail 311 is disposed through the clamping arm 31, and the slide rod 41 is inserted through the slide rail 311. The mobile phone bracket 4 is detachably connected to the slide rod 41. When installing the mobile phone bracket 4 on the clamping arm 31, the slide rod 41 can be first inserted through the slide rail 311 and then connected to the mobile phone bracket 4, which is convenient for assembly. Moreover, the slide rod 41 being inserted through the slide rail 311 can make the sliding of the slide rod 41 smoother.
[0035] Please refer to Figure 6 , a retaining cap 411 is provided at one end of the slide rod 41 away from the mobile phone bracket 4. The outer diameter of the retaining cap 411 is greater than the width of the slide rail 311. The retaining cap 411 can prevent the slide rod 41 from detaching from the slide rail 311. The retaining cap 411 is of a cylindrical structure, which can avoid problems such as sharp corners or edges of a square structure that may cause harm to testers and improve the safety factor. In another embodiment, the retaining cap 411 may also be oval, square or other shapes.
[0036] Please refer to Figure 7, the mobile phone holder 4 further includes a support body 42 and a clamping module 43. The clamping module 43 is disposed at the top end of the support body 42, and its telescopic direction is parallel to the length direction of the support body 42. The support body 42 includes a lifting part 421, a baffle 422 and a storage groove 423. The lifting part 421 protrudes from the bottom end of the storage groove 423 and forms an "L" - shaped structure with the storage groove 423. The baffle 422 covers the lifting part 421 and the storage groove 423. The lifting part 421, the baffle 422 and the storage groove 423 enclose a limiting notch 424. The clamping module 43 is disposed at the top end of the storage groove 423; the clamping module 43 includes a clamping block 431 and telescopic members 432 disposed at both ends of the clamping block 431. The telescopic members 432 are inserted into the storage groove 423. When installing a mobile phone on the mobile phone holder 4, first insert the bottom of the mobile phone obliquely into the limiting notch 424, and then make the mobile phone lie flat in the storage groove 423. The clamping block 431 approaches and abuts against the top of the mobile phone through the telescoping of the retractable member. Preferably, the telescopic member includes an insertion post and a spring. The insertion post includes an insertion part and a limiting part. The insertion part sequentially passes through the clamping block 431 and the support body. The spring is elastically disposed between the clamping block and the limiting part. In the state without a mobile phone assembled, the clamping block 431 abuts against the top of the support body 42 under the action of the spring. At this time, the distance between the clamping block 431 and the lifting part 421 is less than the length of the mobile phone; when a mobile phone needs to be assembled, pull the clamping block 431 away from the support body 42 until the distance between the clamping block 431 and the lifting part 421 is greater than the length of the mobile phone. After placing the mobile phone flat in the storage groove, then release the hand to make the clamping block 431 rebound and clamp the mobile phone. In another embodiment, the spring can also be replaced by an elastic strip. At this time, the elastic strip is disposed between the support body 42 and the clamping block 431. In another embodiment, the clamping module 43 can also be composed of two elastic strips. The two ends of a single elastic strip are disposed at the vertical corner positions at the top of the support body. After the mobile phone is placed flat in the storage groove 423, the elastic strip presses the mobile phone tightly in the storage groove 423.
[0037] The bottom of the scale compass 2 is provided with a mounting shaft 21. The test platform 1 is provided with a shaft hole 13. The mounting shaft 21 is inserted into the shaft hole 13 so that the scale compass 2 is rotatably fixed on the test platform 1.
[0038] The mobile phone compass testing device further includes a base 6, which includes a support platform 61 and a connecting rod 62. The connecting rod 62 is vertically upwardly disposed on the support platform 61. A sleeve 12 is also vertically provided at the bottom of the testing platform 1, and the connecting rod 62 is coaxially inserted into the sleeve 12. The base 6 facilitates the support of the testing platform 1 and makes the placement of the testing platform 1 more stable.
[0039] A plurality of first locking holes 121 are provided through the side wall of the sleeve 12, and a plurality of second locking holes 621 are provided through the side wall of the connecting rod 62. Bolts pass through the first locking holes 121 and the second locking holes 621 to lock the sleeve 12 and the connecting rod 62. The connection by bolts facilitates the disassembly and assembly of the base 6 and the testing platform 1, which is convenient for carrying and maintenance. In another embodiment, the testing platform 1 and the base 6 are integrally formed.
[0040] The first locking holes 121 are arranged at equal intervals along the length direction of the sleeve 12, and the second locking holes 621 are arranged at equal intervals along the length direction of the connecting rod 62. By the misaligned cooperation of the first locking holes 121 and the second locking holes 621, the relative distance between the testing platform 1 and the support platform 61 can be adjusted, achieving the technical effect that the compass testing device can be telescopically adjusted, which is convenient for testers to adjust the height of the testing platform 1 according to the actual working scenario for testing. In another embodiment, the sleeve 12 and the connecting rod 62 can be replaced by telescopic rods.
[0041] A receiving cavity for receiving a weight material is provided inside the support platform 61, and the weight material can be poured in to increase the weight of the support platform 61 and improve stability. Specifically, water or sand and gravel can be poured in for weight increase.
