Description
Technical Field
[0001] The present invention relates to the technical field of wireless charging detection structures, and in particular to a wireless charger detection device and a detection method thereof. Background Art
[0002] Wireless charging technology is a technology that transfers electrical energy from a charging device to an electrical device through an electromagnetic field. In recent years, it has been widely used in fields such as smartphones, electric vehicles, and medical equipment. Compared with traditional wired charging, wireless charging does not require physical contact and transmits energy through the air medium. It has significant advantages in terms of ease of use, waterproofness, and safety. The wireless charging system is mainly composed of a transmitter (charger) and a receiver (charged device). The transmitter converts electrical energy into electromagnetic energy through a coil, and the coil at the receiver converts electromagnetic energy back into electrical energy through electromagnetic induction to achieve the charging process.
[0003] In the wireless charging system, the coil is the core component of energy transmission. The magnetic field generated by the transmitting coil will generate current in the receiving coil through electromagnetic induction, thereby realizing energy transmission. Among them, the distance between the coils and the presence of the medium will have a significant impact on the charging efficiency; the distance between the coils, the alignment and the presence of the medium will have a significant impact on the charging efficiency. For example, the larger the coil spacing, the significantly lower the transmission efficiency will usually be; poor coil alignment will affect the coupling effect of the magnetic field, thereby reducing the charging efficiency; if there is a material such as plastic or glass between the two coils as a medium, the thickness and material properties of the medium will also affect the electromagnetic energy transmission.
[0004] In this regard, the detection scheme proposed by technicians in this field is limited to the proofing test scheme, that is, pre-proofing to obtain a transmitting coil wrapped in one medium and a receiving coil wrapped in another medium, and then performing charge and discharge tests on both to verify whether the overall design of the wireless charging system is reasonable. The above scheme is suitable for the final test scenario during factory production, but in the laboratory scenario, it is necessary to explore the operation of the wireless charging system under various parameters. The proofing test scheme requires proofing coils of various media with different thicknesses, which has the disadvantages of long proofing time and cumbersome operation. Summary of the invention

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

[0051] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.
[0052] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0053] Embodiment 1:
[0054] The wireless charger detection device provided in this embodiment is suitable for quickly testing and evaluating the performance of wireless chargers under different media conditions in a laboratory environment. For example, it can realize charging efficiency testing of different media thicknesses. In this embodiment, the structure of the wireless charger detection device is improved to simplify the cumbersome proofing test process, significantly improve the test efficiency and equipment adaptability, and simplify the operation.
[0055] In the specific application scenario of the wireless charger, the wireless charger includes a transmitting coil and a receiving coil. The transmitting coil converts electrical energy into electromagnetic energy, and the receiving coil converts the electromagnetic energy back into electrical energy through electromagnetic induction to complete the electrical energy transfer. In this charging process, various performance tests are involved, such as charging efficiency test, thermal management performance test, electromagnetic compatibility test, etc. The above performance tests are well known to those skilled in the art and are not specifically expanded in this embodiment. The improvement focus in this embodiment is to provide an efficient, fast and convenient switching method for the test environment of the wireless charger.
[0056] like Figure 1 and Figure 2 As shown, the wireless charger detection device in this embodiment includes a transmitting base 100 and a receiving movable part 200 arranged on a frame 600, and a medium part 300 is arranged on the transmitting base 100. Figure 2As shown, a transmitting station 001 for placing a transmitting coil (not shown) is provided on the transmitting base 100; Figure 5 As shown, a receiving station 002 for placing a receiving coil (not shown) is provided on the receiving movable part 200, and the relative height of the receiving movable part 200 relative to the transmitting base 100 is adjustable; Figures 6 to 9 As shown, the dielectric part 300 is arranged above the emission station 001, and includes a plurality of dielectric sheet groups 310 stacked in sequence along the height direction, and each dielectric sheet group 310 can be switched between a closed state and an open state.
[0057] like Fig. 9 As shown, the dielectric sheet group 310 in the open state forms a first avoidance hole 003 for avoiding the receiving station 002; the test spacing between the receiving station 002 and the transmitting station 001 is greater than or equal to the sum of the thicknesses of the dielectric sheet group 310 in the closed state. It should be noted that the test spacing is controlled by the receiving movable part 200. Since the relative height of the receiving movable part 200 relative to the transmitting base 100 is adjustable, it means that the receiving movable part 200 can drive the receiving coil to move in a direction away from or close to the transmitting coil, so that the test spacing is adjustable.
[0058] Specifically, Figure 6 As shown, the wireless charger detection device is configured with a plurality of stacked dielectric sheet groups 310 above the transmitting station 001, and each dielectric sheet group 310 can be switched between a closed state and an open state, so that the dielectric thickness can be adjusted according to the number of dielectric sheet groups 310 in a closed state. At the same time, other dielectric sheet groups 310 can be in an open state to avoid the receiving coil, which means that there are only a plurality of dielectric sheet groups 310 in a closed state between the receiving coil and the transmitting coil. Therefore, the dielectric thickness can be changed by adjusting the state of each dielectric sheet group 310, and the receiving active part 200 is cooperated to drive the receiving coil to move to change the test spacing, thereby meeting the detection requirements of wireless chargers matching different dielectric thicknesses in laboratory scenarios, saving proofing time and proofing steps, thereby reducing overall time consumption and simplifying steps.
[0059] Furthermore, the wireless charger detection device in this embodiment has at least three test scenarios, including:
[0060] 1. When all the multiple dielectric sheet groups 310 are in an open state, the test spacing is greater than or equal to the thickness of a single dielectric sheet group 310;
[0061] 2. Along the direction away from the transmitting station 001, that is, from bottom to top, when the dielectric sheet groups 310 of a preset number of groups are in a closed state in sequence and the dielectric sheet groups 310 of the remaining number of groups are in an open state in sequence, the test spacing is greater than the thickness sum of the dielectric sheet groups 310 in the closed state, and the spacing where the test spacing exceeds the thickness sum is greater than the thickness of a single group of the dielectric sheet groups 310;
[0062] 3. When all the multiple dielectric sheet groups 310 are in a closed state, the test spacing is greater than or equal to the thickness of the dielectric portion 300 .
[0063] Through the above settings, the wireless charger detection device has the function of increasing the thickness of the medium from zero to the maximum value (the thickness of the medium part 300), or reducing the thickness of the medium from the maximum value to zero, so as to meet the detection requirements of the wireless charger matching different medium thicknesses. For example, as the thickness of the medium increases, the charging efficiency increases accordingly, and as the thickness of the medium decreases, the heat accumulation of the wireless charger becomes more obvious. Through testing at various medium thicknesses, a suitable medium thickness can be selected to meet both the charging efficiency requirements and the safety requirements of heat accumulation.
[0064] In this embodiment, if Figures 6 to 9 As shown, the wireless charger detection device also includes a plurality of mounting plates 400 arranged one by one corresponding to the plurality of dielectric sheet groups 310, and the dielectric sheet groups 310 can be movably mounted on the mounting plates 400; that is, each dielectric sheet group 310 is independently configured with a mounting plate 400. A plurality of mounting posts 110 are arranged on the transmitting base 100 corresponding to a group of mounting plates 400 to support the mounting plates 400.
[0065] The dielectric sheet group 310 includes four dielectric sheet monomers 311 slidably connected to the mounting plate 400. The dielectric sheet monomers 311 are provided with an isosceles right angle portion 312. The four isosceles right angle portions 312 are distributed in a circle, and the isosceles right angle portions 312 are connected to adjacent isosceles right angle portions 312. The mounting plate 400 is also provided with a transmission assembly 500. The transmission assembly 500 is used to drive the dielectric sheet monomers 311 to slide along the extending direction of the right angle side corresponding to the isosceles right angle portion 312. The extending direction of each right angle side is along the same rotation direction. Figure 8 and Fig. 9 As shown, when each dielectric sheet monomer 311 rotates in the clockwise direction and slides along the extension direction of its right-angle side (the upper dielectric sheet monomer 311 slides from left to right, the right dielectric sheet monomer 311 slides from top to bottom, the lower dielectric sheet monomer 311 slides from right to left, and the left dielectric sheet monomer 311 slides from bottom to top), each dielectric sheet monomer 311 is moved away from the circumferential center of the isosceles right-angle portion 312, thereby forming a first avoidance hole 003.
[0066] In a specific test scenario, along the direction away from the transmitting station 001, a portion of the dielectric sheet groups 310 are in a closed state in sequence, and the remaining number of groups of dielectric sheet groups 310 are in an open state in sequence. The receiving movable part 200 can be used to place the receiving coil in the first avoidance hole 003, so that the test spacing is greater than the thickness and thickness of the dielectric sheet group 310 in the closed state, and the spacing by which the test spacing exceeds the thickness and thickness is less than the thickness of a single group of the dielectric sheet group 310.
[0067] It is understandable that, as another optional embodiment, the dielectric sheet group 310 may include six dielectric sheet monomers in the form of equilateral triangles, and these dielectric sheet monomers are evenly distributed in a ring around the center point. The edge of the dielectric sheet monomer away from the center point is the sliding edge, and the transmission assembly 500 can drive the dielectric sheet monomer to slide along the sliding edge.
[0068] Based on the above-mentioned implementation of the four dielectric sheet monomers 311, the dielectric sheet monomers 311 are formed with racks 313 at the right angles; the transmission assembly 500 includes a first gear 510 rotatably connected to the mounting plate 400 corresponding to each rack 313, and also includes a gear ring 530 arranged outside the dielectric sheet group 310, and the gear ring 530 is provided with internal teeth; the mounting plate 400 is provided with a transmission hole 420, and the transmission hole 420 can be rotatably connected to the first gear 510 through a shaft; one end of the first gear 510 is meshed with the internal teeth of the gear ring 530, and the other end of the first gear 510 is meshed with the rack 313. It can be understood that the gear ring 530 can synchronously drive the rotation of multiple first gears 510, and correspondingly drive the rotation of the rack 313, so as to realize the synchronous opening and closing of each dielectric sheet monomer 311.
[0069] Furthermore, the transmission assembly 500 also includes a second gear 520 rotatably connected to the mounting plate 400 through a rotating shaft (not shown in the figure), and the second gear 520 is arranged on the outer side of the gear ring 530 and meshes with the outer teeth of the gear ring 530; along the height direction, the projections of the second gears 520 corresponding to each group of medium sheet groups 310 do not overlap each other. This means that each group of medium sheet groups 310 can realize the conversion between the open state and the closed state through its corresponding second gear 520, so that the independent control of each group of medium sheet groups 310 becomes possible. For example, a plurality of motors with third gears (not shown in the figure) are arranged on the outer ring of the mounting plate 400, and each third gear meshes with a second gear 520, and the state conversion of the corresponding medium sheet group 310 can be realized through the motor, which has the advantages of strong independence and higher flexibility.
[0070] In this embodiment, the mounting plate 400 is rotatably connected with a transmission ring 540 corresponding to the position of the second gear 520 thereof, and the second gear 520 is sleeved outside the transmission ring 540 and fixedly connected with the transmission ring 540; the inner ring surface of the transmission ring 540 is formed with an internal thread, and the internal thread is detachably mounted with a trigger threaded rod 550; the transmission ring 540 can drive the second gear 520 to rotate through the internal thread and the thread of the trigger threaded rod 550. Exemplarily, the height of each trigger threaded rod 550 can be independently controlled by a lifting structure such as a cylinder, a lifting rod motor, etc., that is, the state conversion of the corresponding dielectric sheet group 310 can be realized by a lifting structure such as a cylinder, a lifting rod motor, etc., which has the advantages of strong independence and higher flexibility. At the same time, the structure does not occupy the surface space of the transmitting base 100 additionally, so that the overall space utilization rate is higher, which is conducive to arranging more transmitting stations 001, so that the receiving coil of the receiving station 002 can match and test more scenes in one operation process, which can improve the test efficiency.
[0071] As a preferred embodiment, Figures 3 to 9 As shown, the transmission assembly 500 also includes a second gear 520 rotatably connected to the mounting plate 400 through a rotating shaft (not shown), the second gear 520 is arranged on the outer side of the gear ring 530, and meshes with the outer teeth of the gear ring 530; along the height direction, the projections of the second gears 520 corresponding to each group of medium sheet groups 310 do not overlap each other. The mounting plate 400 is rotatably connected to a transmission ring 540 corresponding to the position of its second gear 520, the second gear 520 is sleeved outside the transmission ring 540, and is fixedly connected to the transmission ring 540; the inner ring surface of the transmission ring 540 is formed with an internal thread, and a trigger threaded rod 550 is detachably installed on the internal thread; the transmission ring 540 can drive the second gear 520 to rotate through the internal thread and the thread of the trigger threaded rod 550.
[0072] Among them, the trigger threaded rods 550 are installed on the receiving movable part 200 in a circular array, and the trigger spacing of the external threaded parts on each trigger threaded rod 550 relative to the receiving station 002 is the same. Since the transmission ring 540 is installed on the mounting plate 400 at different heights, it means that as the receiving station 002 descends, the transmission ring 540 will be driven to rotate one by one by the corresponding trigger threaded rod 550; the projection of each transmission ring 540 on the launch base 100 corresponds to each trigger threaded rod 550 in a circular array, making the overall weight distribution more reasonable and improving the stability. In addition, by adopting the above layout, the state conversion of each dielectric sheet group 310 can be realized without arranging a motor on the launch base 100, which means that this setting can avoid electromagnetic interference components such as motors from interfering with the test at the launch station 001 and the receiving station 002, thereby improving the accuracy of the test, completing the test under different conditions, and simplifying the structure.
[0073] In this preferred embodiment, the external thread of each trigger thread rod 550 should be compatible with the internal thread of the corresponding transmission ring 540. When the trigger thread rod 550 passes through the internal thread of the transmission ring 540, the transmission ring 540 can only rotate because the position of the transmission ring 540 in the height direction is unchanged. Then, after the length and position of the external thread are preset, the trigger thread rod 550 is allowed to pass through the internal thread of the transmission ring 540. Even if the rotation angle of the transmission ring 540 changes accordingly, the rotation angle of the transmission ring 540 can be controlled, and then the state conversion of the medium sheet group 310 can be controlled in cooperation with the second gear 520, the ring gear 530, the first gear 510 and the rack portion 313.
[0074] On this basis, the length of the external threaded portion of the trigger threaded rod 550 is called the transmission pitch, which is the height of the external threaded portion from the "starting position of connection with the internal thread" to the "ending position of connection with the internal thread", that is, the height of the external threaded portion.
[0075] Illustratively, in this embodiment, the receiving movable part 200 is provided with 8 trigger threaded rods 550 distributed in a circle, and along the height direction, the 8 external threaded parts are connected end to end to ensure that each medium sheet group 310 can switch the state respectively, and the installation height of the mounting plate 400 where each transmission ring 540 is located is matched one by one.
[0076] More specifically, in order to ensure that the receiving coil does not collide with the dielectric portion 300, the transmission spacing can be made equal to the thickness of the single dielectric sheet 311. For this purpose, the test spacing in different test scenarios can be set:
[0077] 1. When all the multiple groups of dielectric sheet groups 310 are in the closed state, a transmission gap is left between the receiving station 002 and the uppermost dielectric sheet group 310. The test gap is equal to the sum of the thickness of the dielectric part 300 and the transmission gap, so as to ensure that the receiving coil on the receiving station 002 will not collide with the dielectric part 300. The transmission ring 540 of the uppermost dielectric sheet group 310 begins to mesh with the trigger threaded rod 550.
[0078] 2. The receiving movable part 200 drives the receiving station 002 to move down by the thickness of a single dielectric sheet 311. Since the transmission spacing is equal to the thickness of the single dielectric sheet 311, the transmission ring 540 of the uppermost dielectric sheet group 310 ends the engagement with the trigger threaded rod 550, so that the dielectric sheet group 310 enters the open state; at this time, the test spacing should be equal to the sum of the thickness of the 7 dielectric sheet groups 310 and the transmission spacing;
[0079] 3. The process is repeated in the same manner until all the dielectric sheet groups 310 enter the open state and the test spacing is equal to the transmission spacing.
