Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] An embodiment of this utility model: A portable handheld display device for angle and displacement sensors includes a carrying case 1. A rigid foam liner A2 is fixedly installed inside the carrying case 1. The surface of the rigid foam liner A2 has a recessed structure. A mounting base plate 3 is provided on the surface of the rigid foam liner A2. A displacement sensor testing device 4 and two large mounting holes are provided on the mounting base plate 3. An angle sensor testing device 5 is fixed at one of the large mounting holes, and a display screen 7 is fixed at the other large mounting hole. The angle sensor testing device 5 includes a circular PCB board 6 located at the large mounting hole. Multiple angle sensors are distributed on the PCB board 6. A rotary motor bracket 8 is provided on the lower back of the PCB board 6. The rotary motor bracket 8 is fixed on the mounting base plate 3. A rotary motor 9 is fixed on the rotary motor bracket 8. A rotary swing rod 10 is fixedly sleeved on the output shaft of the rotary motor 9. A magnet 11 is provided on the top surface of the rotary swing rod 10.

[0018] After installing all components onto the mounting base plate 3, the connections between them need to be completed. PCB board 6 is electrically connected to display screen 7 and rotary motor 9. Before testing PCB board 6 and display screen 7, an external power supply is required. The recessed structure on the surface of the rigid foam liner A2 provides the corresponding installation space for the back structure of mounting base plate 3 (rotary motor bracket 8, rotary motor 9, and corresponding connecting lines). Display screen 7 also displays product information for the corresponding angle and displacement sensors, as well as corresponding test programs. During the demonstration, the display screen 7 can show the relevant product information. If angle sensor testing is required, the angle sensor test program on display screen 7 can be started, and the corresponding test parameters can be set on display screen 7. Display screen 7 controls the rotation of rotary motor 9, which in turn drives the rotating arm 10 to rotate. When the magnet 11 at the top of the rotating arm 10 rotates to different positions of the angle sensor, it will ultimately feed back the rotation angle signal information to display screen 7, displaying the feedback signal parameters, such as the rotation speed of rotary motor 9 and the rotation angle of rotating arm 10.

[0019] The displacement sensor testing device 4 includes two mounting bases 12 fixed to the mounting base 3 by screws. A mounting tube 13 connects the two mounting bases 12. A float 14 is movably sleeved on the mounting tube 13. The displacement sensor (magnetoresistive level band) to be tested is placed in the mounting tube 13. The wiring terminal of the magnetoresistive level band extends to the bottom of the mounting base 3 and is connected to the display screen 7. The display screen 7 supplies power to the magnetoresistive level band, and the magnetoresistive level band feeds back the corresponding position signal to the display screen 7. When the displacement sensor (magnetoresistive level band) needs to be tested, the displacement sensor test program on the display screen 7 is started, so that the magnetoresistive level band is powered on. The float 14 is manually moved to move linearly along the mounting tube 13. At this time, the magnetoresistive level band can feed back the signal information of the position of the float 14 to the display screen 7, and display it on the display screen 7.

[0020] The mounting base plate 3 is also provided with multiple small mounting holes 15, one of which is equipped with a power plug 16. One end of the power plug 16 is used to connect to an external power source, and the other end is connected to the PCB board 6 and the display screen 7 to provide power to various electrical devices. When on-site testing / demonstration is required, simply plug the power supply into the power plug 16 to provide power. Some of the other small mounting holes 15 are designed to allow a hand to be inserted into them to hold the mounting base plate 3, thus facilitating its insertion into the rigid foam liner A2. The small mounting hole 15 on the right side of the mounting tube 13 is for facilitating the insertion of the wiring terminal of the magnetic resistance level strip into the bottom of the mounting base plate 3 to connect with the display screen 7.

[0021] It also includes a suitcase lid 17, in which a rigid foam liner B18 is provided. The surface of the rigid foam liner B18 is provided with an outwardly protruding limiting block 19. When the suitcase lid 17 is closed, the limiting block 19 on the surface of the rigid foam liner B18 will abut against the surface of the mounting base plate 3, thereby limiting and fixing the mounting base plate 3 and preventing the mounting base plate 3 from shaking inside the suitcase during movement.

[0022] The rigid foam liner A2 has an embedded mounting base plate 3, which facilitates the installation and removal of the mounting base plate 3. The rigid foam liner A2 itself can effectively fix the mounting base plate 3 in place.

[0023] The edge of the PCB board 6 is supported on the mounting base plate 3 and is fixedly connected to the mounting base plate 3 by screws; the bottom of the display screen 7 is provided with a mounting plate, the display screen 7 extends out from one of the large mounting holes, the mounting plate contacts the bottom surface of the mounting base plate 3 and is fixedly connected to the mounting base plate 3 by screws, thereby fixing the PCB board 6 and the display screen 7 well to the mounting base plate 3.

[0024] The structure of this utility model is not limited to testing / displaying angle sensors and displacement sensors. When it is necessary to test / display other electronic products, the corresponding electronic product testing device can be fixed on the mounting base plate 3.

[0025] Furthermore, the structure of this invention avoids the problems of interference during testing wiring for different types of products and errors in line identification. This invention uses modular and zoned wiring for connecting different types of electronic components, avoiding the time-consuming, labor-intensive, and error-prone phenomenon when switching between tests of different products. Since the various components have been pre-assembled and connected, there is no need for on-site assembly, saving testing time. Moreover, the testing device does not need to be repeatedly disassembled and reassembled, reducing the probability of device failure.

[0026] Since the structure of this utility model is relatively simple, mainly including displacement sensor testing device 4, angle sensor testing device 5 and display screen 7, its main purpose is to test and demonstrate a certain main performance of the product, and it cannot replace laboratory testing equipment to test various performance parameters of the product.

[0027] For some parts that require motion display, the rotating structure of the test structure should be as simple and reliable as possible. This utility model places the rotating device on the back of the mounting base plate 3, while the overall structure is embedded in the rigid foam lining A2 frame. The overall structure is simple, reliable and practical.
