[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Please refer to the comprehensive Figure 3 and Figure 4 An embodiment of the present invention provides a test stand for detecting changes in various performance parameters of a transmitting module and a receiving module mounted on a device when the transmitting module and the receiving module are in different relative positions.

[0046] The test stand of this embodiment includes an adjustment base 1, an adjustment structure 2, a transmission structure 3, a guide structure 4, and a movable structure 5. The adjustment structure 2 and the transmission structure 3 are both mounted on the adjustment base 1, and the adjustment structure 2, the transmission structure 3, and the movable structure 5 are sequentially connected in a transmission manner. The adjustment structure 2 is configured for external manual adjustment. The movable structure 5 is configured to carry the module to be tested. The guide structure 4 is mounted on the adjustment base 1 and extends along a first direction. The movable structure 5 is slidably connected to the guide structure 4 and moves along the guide structure 4.

[0047] This embodiment adopts an adjustment structure 2 that can be manually adjusted. When in use, the inspection personnel can manually drive the adjustment structure 2, and the adjustment structure 2 controls the operation of the transmission structure 3. Under the transmission action of the transmission structure 3, the mobile structure 5 moves in the first direction, thereby adjusting the position of the module to be tested mounted on the mobile structure 5 in the first direction.

[0048] For example usage scenarios, please refer to Figure 1 and Figure 2 The wireless charging module 10 to be tested includes a transmitting module 10a and a receiving module 10b. The transmitting module 10a and the receiving module 10b can use the alternating magnetic field generated between each other's coils to achieve the transmission of electrical energy. The receiving module 10b can be set in a functional device, such as assembled in the body of a snowplow. The transmitting module 10a is usually set in a charging device, such as assembled in a charging base. One of the transmitting module 10a and the receiving module 10b is fixed in position, and the other is carried by a test stand with a mobile function, so that the position between the two can be achieved. The receiving module 10b or the device equipped with the receiving module 10b can be fixed in a certain position. As a reference solution, Figure 1 As shown, the receiving module 10b or the device equipped with the receiving module 10b can be fixed on the top of the guide structure 4; as another reference solution, a rack can be set up to mount the receiving module 10b or the device equipped with the receiving module 10b to a fixed position. The transmitting module 10a or the device equipped with the transmitting module 10a is then installed on the mobile structure 5. The transmitting module 10a or the device equipped with the transmitting module 10a can move along with the mobile structure 5, thereby changing the relative position of the transmitting module 10a and the receiving module 10b in the first direction, and achieving the proximity or distance between the transmitting module 10a and the receiving module 10b. It is understandable that the transmitting module 10a and the receiving module 10b can exchange positions, that is, the transmitting module 10a or the device equipped with the transmitting module 10a is fixed at a certain position, and the receiving module 10b or the device equipped with the receiving module 10b is mounted on the mobile structure 5.

[0049] It should be noted that the module to be tested may be a module or device that needs to be tested, for example, the module to be tested may be a transmitting module 10a or a device equipped with a transmitting module 10a, and the module to be tested may be a receiving module 10b or a device equipped with a receiving module 10b, such as a snowplow, etc. This embodiment can also be applied to the detection of other devices that need to adjust the relative position, and is not limited to wireless charging devices.

[0050] In some optional embodiments, a placement portion 6 is provided on the top of the guide structure 4 for carrying the module to be tested, for example, carrying one of the transmitting module 10a and the receiving module 10b, while the other is carried on the mobile structure 5. The placement portion 6 can be a plurality of supporting plates, such as Figure 1 As shown in , it is used to support the module to be tested. Alternatively, the placement portion 6 is a platform, and the platform can place the module to be tested.

[0051] In this way, the tester can manually control the adjustment structure 2 to adjust the position of the receiving module 10b relative to the transmitting module 10a in the first direction, thereby facilitating measurement of changes in various performance parameters when the transmitting module 10a and the receiving module 10b are in different relative positions. This embodiment uses a manually controlled adjustment structure 2 to adjust the position of the mobile structure 5 and the module under test mounted on the mobile structure 5, eliminating the need for a motor or other drive device. This effectively reduces costs, meets the needs of low-cost testing, and facilitates flexible and instant manual position adjustment.

[0052] The guide structure 4 is used to guide the moving structure 5 to move in a first direction.

[0053] In some optional embodiments, the guide structure 4 may include at least one support column 41, which passes through the movable structure 5, and the movable structure 5 moves along the support column 41. The number and shape of the support columns 41 can be adjusted according to actual needs. As an optional solution, the guide structure 4 includes four support columns 41, each of which is erected on the adjustment seat 1, and each of which passes through the movable structure 5. Such an arrangement can provide a more stable and reliable supporting force, as well as a more stable guiding effect. Optionally, the position on the movable structure 5 through which the support column 41 passes can be equipped with an anti-damage part 511. The anti-damage part 511 can be, but is not limited to, a self-lubricating kit to reduce friction and loss. In this embodiment, the anti-damage part 511 is a graphite copper sleeve. As another optional solution, the guide structure 4 includes a non-cylindrical support column 41, such as a rectangular column, which passes through the movable structure 5 to achieve guidance while circumferentially limiting the movable structure 5.

[0054] In some optional embodiments, the transmission structure 3 includes a screw mechanism 31, a transmission wheel 32, and a flexible member 33. The transmission wheel 32 is connected to the screw mechanism 31. The transmission wheel 32 and the screw mechanism 31 are coaxial and rotate synchronously. The transmission wheel 32 and the screw mechanism 31 are integrally rotatably connected to the adjustment base 1. The screw mechanism 31 is threadedly connected to the movable structure 5. The adjustment structure 2 is flexibly connected to the flexible member 33, and the flexible member 33 is flexibly connected to the transmission wheel 32. When the adjustment structure 2 rotates, the flexible member 33 moves, and the flexible member 33 in turn drives the transmission wheel 32 to rotate.

[0055] During operation, the inspector manually controls the adjustment structure 2, which drives the flexible member 33. The flexible member 33 then drives the transmission wheel 32 and the screw mechanism 31 to rotate as a whole. Because the screw mechanism 31 and the movable structure 5 are threadedly connected, and under the action of the guide structure 4, when the screw mechanism 31 rotates, the movable structure 5 moves in the first direction. Optionally, the first direction can be the vertical direction.

[0056] The transmission wheel 32 and the screw mechanism 31 are integrally rotatably connected to the adjustment base 1. As one example, the screw mechanism 31 is rotatably connected to the adjustment base 1, the transmission wheel 32 is sleeved on the screw mechanism 31, and the transmission wheel 32 is circumferentially limited on the screw mechanism 31; as another example, the transmission wheel 32 is rotatably connected to the adjustment base 1, and the screw mechanism 31 and the transmission wheel 32 are plugged and circumferentially limited.

[0057] Optionally, a single transmission wheel 32 and a single screw mechanism 31 are used as a set, and the adjustment seat 1 may be provided with two or more sets of the above sets to increase transmission stability.

[0058] The above-mentioned flexible transmission connection can be a friction type transmission connection and a meshing type transmission connection. The friction type transmission can be a belt transmission or a rope transmission, and the meshing type transmission can be a belt transmission connection or a chain transmission connection.

[0059] Optionally, the screw mechanism 31 includes a screw 311, which is threadedly connected to the movable structure 5. When the screw 311 rotates, the movable structure 5 is guided by the guide structure 4 and moves in the first direction. The screw 311 can be, but is not limited to, a T-shaped screw.

[0060] In some optional embodiments, such as Figure 4 As shown in , the screw 311 can be rotatably connected to the adjustment seat 1 by setting a screw bearing 13. For example, the adjustment seat 1 has a bearing seat 12, and the screw bearing 13 is assembled in the bearing seat 12. One end of the screw 311 passes through the transmission wheel 32 and is plugged into the screw bearing 13.

[0061] In some optional embodiments, the screw mechanism 31 further includes a buffer 312, which is sleeved on the screw 311 and located between the screw 311 and the transmission wheel 32 to provide shock absorption and noise reduction. The buffer 312 can separate the transmission wheel 32 to protect the transmission wheel 32. The buffer 312 can be an elastic member, such as a rubber pad.

[0062] The adjustment structure 2 can be a rotary structure, allowing the inspector to control the operation of the transmission structure 3 by rotating it. In some optional embodiments, the adjustment structure 2 includes an adjustment wheel 21 and an adjustment shaft 22. The adjustment shaft 22 is rotatably connected to the adjustment base 1. The adjustment wheel 21 is sleeved around the outer periphery of the adjustment shaft 22, and the adjustment wheel 21 and the adjustment shaft 22 are circumferentially limited to ensure synchronous rotation of the adjustment wheel 21 and the adjustment shaft 22. The adjustment wheel 21 is in flexible transmission connection with the flexible member 33.

[0063] The inspector can manually rotate the adjusting shaft 22 , which drives the adjusting wheel 21 to rotate, and the adjusting wheel 21 drives the flexible member 33 to operate, and the flexible member 33 further drives the screw mechanism 31 to rotate.

[0064] The flexible member 33 can realize transmission over a longer distance. The flexible member 33 can be an elastic structure to mitigate impact and absorb vibration.

[0065] For example, the adjusting shaft 22 can be rotatably connected to the adjusting seat 1 by providing a bearing. The adjusting seat 1 is provided with a first bearing, and the adjusting shaft 22 is plugged into the first bearing.

[0066] In some optional embodiments, the flexible member 33 is a synchronous toothed belt. The flexible member 33 meshes with the adjustment wheel 21, which in turn meshes with the transmission wheel 32. This effectively prevents the flexible member 33 from slipping relative to the transmission object, ensuring a stable and reliable transmission process. The synchronous toothed belt has teeth on its inner ring, while both the adjustment wheel 21 and the transmission wheel 32 have teeth on their outer circumferences for meshing with the synchronous toothed belt.

[0067] In some optional embodiments, please refer to Figure 3 and Figure 4 The transmission structure 3 also includes a tensioning wheel 34 , which is arranged on the adjustment seat 1 . The tensioning wheel 34 is used to press the flexible member 33 to achieve a tensioning effect on the flexible member 33 .

[0068] Optionally, a slot 11 is formed on the adjustment base 1, and the tensioning wheel 34 is slidably connected to the slot 11 and moves along the slot 11. In this way, the force with which the tensioning wheel 34 presses against the flexible member 33 can be adjusted, allowing the inspector to adjust the tension of the flexible member 33 to ensure normal operation of the transmission structure 3. The tensioning wheel 34 can be an idler wheel.

[0069] Optional, such as Figure 3 As shown in , the tensioning wheel 34 may include a wheel body and a central shaft, the wheel body is sleeved on the central shaft, and the central shaft is slidably connected in the sliding groove 11.

[0070] The mobile structure 5 can adopt a structure of no movement, single axis or multi-axis movement according to actual conditions. In some optional embodiments, the mobile structure 5 can be set as a structure of two-axis movement.

[0071] As an optional embodiment, please refer to Figure 3 and Figure 4 The movable structure 5 includes a base 51, a first movable platform 52, a second movable platform 53, a first guide structure 54, and a second guide structure 55. The base 51 is slidably connected to the guide structure 4 and is threadedly connected to the screw mechanism 31. The first guide structure 54 extends along the second direction and is disposed on the base 51. The first movable platform 52 is slidably connected to the first guide structure 54. The second guide structure 55 extends along the third direction and is disposed on the first movable platform 52. The second movable platform 53 is slidably connected to the second guide structure 55. The second movable platform 53 is used to carry the module to be tested.

[0072] During use, if the position of the module carried by the second movable platform 53 needs to be adjusted in the second direction, the inspection personnel can push and pull the position of the first movable platform 52; if the position of the module carried by the second movable platform 53 needs to be adjusted in the third direction, the inspection personnel can push and pull the second movable platform 53.

[0073] In this way, the movable direction of the module under test mounted on the mobile structure 5 can be increased, so that the tester can adjust the relative position between the transmitting module 10a and the receiving module 10b. Moreover, the adjustable range along the first direction, the second direction, or the third direction is relatively large, which can be used with a variety of devices and has high versatility.

[0074] The first direction, the second direction and the third direction are all different directions. For example, the first direction can be set to a vertical direction, the second direction can be set to a left-right direction, and the third direction can be set to a front-back direction.

[0075] The base 51 is threadedly connected to the screw mechanism 31. As one example, the base 51 is a plate having a threaded hole formed therein, into which the screw mechanism 31 is inserted. As another example, the base 51 includes a main body and a threaded member 512 disposed on the main body, which is threadedly connected to the screw mechanism 31. The threaded member 512 may be, but is not limited to, a nut. Optionally, the screw 311 may be, but is not limited to, a T-shaped screw, adapted to the threaded member 512. The T-shaped screw has a self-locking function, enabling the movable structure 5 to hover arbitrarily and preventing the movable structure 5 from slipping. After adjustment by the adjustment structure 2, there is no need to additionally limit the movable structure 5.

[0076] Optionally, the first guide structure 54 includes a first guide rail 541 extending along the second direction and disposed on the base 51. A first slider 542 is slidably connected to the first guide rail 541. The first movable platform 52 is fixed to the first slider 542 and moves along the first guide rail 541 following the first slider 542. The second guide structure 55 includes a second guide rail 551 extending along the third direction and disposed on the first movable platform 52. A second slider 552 is slidably connected to the second guide rail 551. The second movable platform 53 is fixed to the second slider 552 and moves along the second guide rail 551 following the second slider 552.

[0077] In some optional embodiments, such as Figure 3 As shown in the figure, a first limit member 56 is provided on the base 51, and the first limit member 56 is located within the moving range of the first movable platform 52, and the first movable platform 52 is used to abut against the first movable platform 52; and / or, a second limit member 57 is provided on the first movable platform 52, and the second limit member 57 is located within the moving range of the second movable platform 53, and the second limit member 57 is used to abut against the second movable platform 53.

[0078] The first stopper 56 is used to limit the range of movement of the first movable platform 52. Before testing, the position of the first movable platform 52 can be adjusted so that it abuts against the first stopper 56. This allows for preliminary positioning of the module under test in the second direction as a foolproof design to improve testing efficiency. Further position adjustments can be made later based on actual needs.

[0079] Similarly, the second stopper 57 is used to limit the range of movement of the second movable platform 53. Before testing, the position of the second movable platform 53 can be adjusted so that it abuts the second stopper 57. This allows for preliminary positioning of the module under test in its initial position in the third direction, as a foolproof design to improve testing efficiency. Further position adjustments can be made later based on actual needs.

[0080] like Figure 4 As shown in , the first limiting member 56 can be a first limiting block, which is fixed to the base 51 by screws. Similarly, the second limiting member 57 can be a second limiting block, which is fixed to the first movable platform 52 by screws.

The first marker 42 may be a scale marker. When the movable structure 5 moves along the guide structure 4, the first marker 42 can be used to identify the position of the movable structure 5. The first marker 42 may also be a sticker, a reference line, or other markers, which are not described here.

[0082] Optional, such as Figure 4 As shown in FIG, a second marker 521 is provided on the first movable platform 52, and the second marker 521 is used to identify the position information of the first movable platform 52 in the second direction. As an example, the second marker 521 can be set as an observation plate, and the observation plate moves with the first movable platform 52. A scale marker can also be provided on the base 51 or / and the first guide structure 54, for example Figure 4 The first scale mark 513 shown in FIG. 5 is provided to facilitate viewing the movement of the observation plate. As another example, the second mark 521 can be provided as a scale mark, and a reference line or an observation plate can be provided on the base 51 and / or the first guide structure 54 to facilitate viewing the movement of the observation plate.
