Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging test, and more specifically, to a tooling for testing low-power wireless charging equipment. Background Art

[0002] In the field of wireless charging, the Qi protocol of WPC (Wireless Power Consortium) has become the mainstream standard in the market due to its wide compatibility and recognition. The Qi protocol supports a wide range of product types, including consumer electronic products such as mobile phones, watches, and headphones. In the development and certification process of the above products, it is crucial to ensure the correctness of the charging area, especially after the launch of the Qi2.0 protocol, there are strict requirements for the accuracy of the charging position; therefore, the test of the coupling effect at different distances has become a key step in the successful launch of the product, and any small deviation may affect the certification result of the product.

[0003] In the prior art, in order to meet the requirements for different test positions of the equipment, the following methods are generally used:

[0004] 1. Fix the transmitter device and use the three-axis motor to move the receiver device in the X, Y, and Z directions to achieve testing at different positions. This solution is difficult to accurately locate whether the centers of the two coils are aligned. It can only rely on the displacement of the receiver device and the theoretical calculation of the center point of electrical performance parameters such as efficiency. In addition, in the magnetic wireless charging system, the coils of the transmitter device and the receiver device contain magnets, and the motor movement cannot adapt to different sizes of magnetic attraction.

[0005] 2. Place positioning paper on the surface of the transmitter device and calibrate the center line of the receiver device, and test by manually aligning the positioning grid. This has great deficiencies in test position stability and accuracy; problems such as the inability to reproduce test results often occur;

[0006] The positioning accuracy of the above method is greatly reduced and cannot meet the needs of testing low-power wireless charging equipment. Utility Model Content

[0046] The utility model is described in detail below.

[0047] Embodiment 1:

[0048] like Figure 1-Figure 9 As shown:

[0049] A tool for testing low-power wireless charging equipment, comprising an RX fixing component 1 for clamping and fixing a receiving-end device and moving along the Z-axis direction, a TX clamping and fixing component 2 located below the RX fixing component 1 and for clamping and fixing a transmitting-end device, a three-dimensional adjustment mechanism for supporting the TX clamping and fixing component 2 and controlling the movement of the TX clamping and fixing component 2 in the X-axis, Y-axis, and Z-axis directions, a base 4 for installing the TX fixing end and the RX fixing component 1, and a positioning rod for positioning the RX fixing component 1 and the TX clamping and fixing component 2; the RX fixing component 1 is provided with an RX positioning through hole 11, and the TX clamping and fixing component 2 is provided with a TX positioning hole 21 used in conjunction with the RX positioning through hole 11 and the positioning rod;

[0050] The sizes of the RX positioning through hole 11, the positioning rod, and the TX positioning hole 21 are adapted;

[0051] When in use, firstly, the RX positioning through hole 11 is controlled by the positioning rod to be coaxial with the TX positioning hole 21, so as to realize the reset of the RX fixing component 1 and the TX clamping fixing component 2;

[0052] Then install the transmitter device on the TX clamping and fixing component 2 and clamp it;

[0053] Then the receiving device is installed on the transmitting device. Since both the receiving device and the transmitting device are provided with magnetic ring coils, the magnetic ring coils in the transmitting device and the receiving device are made coaxial through magnetic attraction and contact.

[0054] The RX fixing component 1 is controlled to move toward the side close to the TX clamping fixing component 2, and the receiving end device is clamped and fixed; the receiving end device and the transmitting end device are installed, and the magnetic ring coils of the two are coaxially arranged;

[0055] Finally, the three-dimensional adjustment device is used to adjust in the X-axis, Y-axis and Z-axis directions, so as to achieve the test of the transmitting device at different positions relative to the receiving device, with high test efficiency and high test accuracy;

[0056] In some possible implementations, in order to effectively achieve the clamping and fixing of the corresponding receiving end device;

[0057] like Figure 2 , Figure 3 As shown, the RX fixing assembly 1 includes a Z guide shaft 10 mounted on the base 4 and arranged in the Z-axis direction, an RX clamping frame 12 sleeved on the outside of the Z guide shaft 10 and used to clamp and fix the receiving end device, and an RX locking member used to lock the RX clamping frame 12 and the Z guide shaft 10;

[0058] Specifically, there are multiple groups of Z guide shafts 10, and the RX clamping frame 12 is mounted on the outside of the multiple groups of Z guide shafts 10 and can move along the axial direction thereof, so as to realize the position adjustment of the RX clamping frame 12 in the Z-axis direction. When the position of the RX clamping frame 12 is adjusted to the right position and the receiving end device is clamped and fixed, it is locked with the Z guide shaft 10 through the RX locking member to prevent movement;

[0059] In order to effectively realize the clamping and fixing of the receiving end device; the RX clamping frame 12 is provided with a mounting cavity 13, two sets of X-direction abutments 14 arranged in parallel and moving along the X-axis direction, and two sets of Y-direction contact abutments 15 arranged in parallel and moving along the Y-axis direction on one side thereof close to the TX clamping and fixing component 2; the two sets of X-direction abutments 14 and the two sets of Y-direction contact abutments 15 cooperate with each other to form an RX clamping groove for clamping and fixing the receiving end device; a boss 16 is coaxially arranged with the RX clamping groove in the clamping cavity; the RX positioning through hole 11 is arranged on the boss 16 and coaxial with the boss 16; the RX positioning through hole 11 runs through the RX clamping frame 12;

[0060] Preferably, the RX clamping groove is square or circular;

[0061] When the positioning rod passes through the RX positioning through hole 11 but does not enter the TX positioning hole 21, it means that the boss 16 of the RX fixing component 1 is not coaxial with the support platform 24 of the TX clamping and fixing component 2. At this time, the TX clamping and fixing component 2 is adjusted in the X-axis and / or Y-axis direction by the three-dimensional adjustment device, so as to complete the coaxial reset of the support platform 24 and the boss 16, and then the transmitting end device and the receiving end device are clamped and fixed in turn;

[0062] When clamping and fixing the receiving-end device, the receiving-end device is installed on the transmitting-end device. After the coil is coaxial through the magnetic attraction of the magnetic ring coil, the RX clamping frame 12 is controlled to move toward the side close to the transmitting-end device, and the transmitting-end device is located in the installation cavity 13 and the bottom of the boss 16 is abutted against the top of the transmitting-end device, and the receiving-end device is installed in the RX clamping groove; then, the X-direction abutment 14 and the Y-direction contact abutment 15 are controlled to move in the installation cavity 13, so that the inner side surfaces of the two groups of X-direction abutment 14 and the two groups of Y-direction contact abutment 15 are respectively abutted against the outer side surface of the receiving section, so that the receiving-end device is clamped and fixed.

[0063] In order to effectively clamp and fix the receiving end device through the X-direction abutment member 14 and the Y-direction contact abutment member 15 at one end in the installation cavity 13;

[0064] like Figure 3 As shown, the X-direction abutment member 14 has the same structure as the Y-direction contact abutment member 15, including an RX screw rod 141 with one end passing through the installation cavity 13 and extending into the boss 16, an abutment bar 142 located in the installation cavity 13 and threadedly engaged with the RX screw rod 141, and a guide rod 143 arranged parallel to the screw rod and connected to the boss 16 and the RX clamping frame 12 at both ends;

[0065] Furthermore, the abutment strip 142 is a rubber strip supported by rubber or silicone material; thus, hard contact with the receiving end device is avoided;

[0066] In the X-direction abutment member 14, the length direction of the abutment bar 142 is arranged along the Y-axis direction; the guide rods 143 are in two groups and are located on both sides of the corresponding RX screw rods 141, and the guide rods 143 are sleeved in the abutment bar 142; the RX screw rods 141 are arranged along the X-axis direction, one end of the RX screw rods 141 extends into the boss 16 and the other end is located outside the RX clamping frame 12;

[0067] When adjusting the position of the abutting bar 142, the RX screw 141 is screwed. Since the abutting bar 142 is sleeved on the outside of the guide rod 143 and is screwed to the RX screw 141, the abutting bar 142 can only move along the long direction of the RX screw 141, that is, along the X-axis direction.

[0068] In the Y-direction contact abutment member 15, the length of the abutment bar 142 is set along the X-axis direction; the RX screw 141 is set along the X-axis direction; its working principle is the same as that of the X-direction abutment member 14; it drives the corresponding abutment bar 142 to move along the Y-axis direction;

[0069] By controlling the movement of the four groups of abutment bars 142, the abutment bars 142 are brought into abutment with the outer side surface of the receiving-end device, thereby achieving clamping and fixing of the receiving-end device.

[0070] In some possible implementations, in order to effectively clamp and fix the transmitting end device;

[0071] like Figure 4 As shown, the TX clamping and fixing assembly 2 includes a TX fixing frame 22 installed on the three-dimensional adjustment mechanism and provided with a mounting groove on the top, and a plurality of clamping members 23 installed on the TX fixing frame 22 and cooperating with each other to form a TX clamping cavity; the clamping members 23 are slidably matched with the TX fixing frame 22;

[0072] A support platform 24 coaxially arranged with the mounting groove is arranged in the TX clamping cavity; the TX positioning hole 21 is arranged on the support platform 24 and coaxially with the support platform 24;

[0073] The clamping member 23 includes a plurality of clamping blocks 231 located in the installation groove and slidingly matched with the TX fixing frame 22, and a TX threaded rod 232 arranged one-to-one with the clamping blocks 231 and used to control the movement of the clamping blocks 231 in the installation groove;

[0074] One end of the TX threaded rod 232 is located outside the TX fixing frame 22, and the other end thereof extends into the installation slot and is connected to the clamping block 231, and the TX threaded rod 232 is threadedly matched with the TX fixing frame 22;

[0075] Preferably, the clamping blocks 231 are four groups and are arranged one by one with the TX threaded rods 232, and the clamping cavity formed is circular or square, which is specifically determined according to the shape of the transmitting end device;

[0076] The coaxiality of the RX clamping frame 12 and the TX fixing frame 22 is adjusted through the RX positioning through hole 11 and the TX positioning hole 21, thereby resetting the RX clamping frame 12 and the TX fixing frame 22; when the three-dimensional adjustment mechanism is adjusted in the X-axis or Y-axis direction, the problem of insufficient stroke due to non-resetting is avoided, thereby affecting the test range;

[0077] The transmitting end device is mounted on the supporting platform 24. Specifically, by twisting the TX threaded rod 232, the clamping block 231 is controlled to move in the TX clamping cavity to clamp and fix the transmitting end device.

[0078] After the transmitter device is fixed in place, the clamping block 231 and the TX fixing frame 22 can be fixed to avoid relative movement during the test. The inner side of the clamping block 231 will abut against the outer side of the transmitter device to clamp and fix the transmitter device.

[0079] In some possible implementations, in order to effectively implement the requirement of testing the transmitting end device at a different location relative to the receiving end device;

[0080] like Figure 4-Figure 9 As shown, the three-dimensional adjustment mechanism includes a vertical adjustment device 31 connected to the bottom of the TX clamping and fixing component 2, and a two-dimensional adjustment device installed at the bottom of the vertical adjustment device 31 and realizing adjustment in the X-axis and Y-axis directions.

[0081] The vertical adjustment device 31 includes a sliding frame 311 installed at the bottom of the TX fixing frame 22 and moving along the Z-axis direction, a bracket 312 installed on the two-dimensional adjustment device and slidingly matched with the sliding frame 311, and a vertical driving member 313 installed on the bracket 312 and used to control the sliding frame 311 to slide along the Z-axis direction;

[0082] The vertical drive member 313 is used to adjust the transmitting end device relative to the receiving end in the Z-axis direction during the test, and can be driven by a linear drive mechanism in the prior art to move in the Z-axis direction, such as a linear electric push rod, a hydraulic telescopic cylinder, etc.;

[0084] This enables testing of the transmitter device and the receiver device at different locations;

[0085] In some possible implementations, in order to effectively implement position adjustment of the TX clamping and fixing assembly 2 in the Z-axis direction;

[0086] The bracket 312 includes a bottom plate mounted on the two-dimensional adjustment device, and a side plate 3121 mounted on the bottom plate and enclosing a mounting groove;

[0087] like Figure 6 , Figure 7 As shown, in order to provide control over the movement accuracy in the Z-axis direction, the vertical driving member 313 includes an adjustment block 3131 located in the installation groove and rotatably matched with the side plate 3121, an abutment column 3132 installed at the bottom of the sliding frame 311 and used in conjunction with the adjustment block 3131, a Z-direction adjustment micrometer 3133 with one end passing through the side plate 3121 and abutting against the adjustment block 3131, and a locking assembly 3134 for locking the bracket 312 and the side plate 3121;

[0090] When adjusting the Z-axis direction, the micrometer screw of the Z-axis adjustment micrometer 3133 is turned to make the micrometer screw move toward the side close to the adjustment block 3131 and abut against the rotating block 31312. The micrometer screw is continuously turned, and the adjustment block 3131 will rotate the end abutting against the micrometer screw toward the side away from the Z-axis adjustment micrometer 3133, and make the rotating block 31312 abut against the bottom of the abutting column 3132. Due to the continuous turning of the micrometer screw, the abutting column 3132 is driven by the rotating block 31312 to move toward the side close to the RX fixed component 1 along the Z-axis direction, thereby preventing it from moving away from the RX fixed component 1 along the Z-axis direction. Thus, the position of the receiving end device and the fixed end device in the Z-axis direction can be adjusted.

[0091] Specifically, the rotating block 31312 includes a rotating part which is sleeved on the outside of the rotating shaft 31311 and rotates with the rotating shaft 31311, a first part which is connected to the rotating part and abuts with one end of the Z-axis adjustment micrometer 3133 extending into the installation groove, and a second part which is connected to the rotating part and the other end of which is connected to the abutting column 3132.

[0092] Further, the abutment column 3132 is coaxially arranged with the bracket 312;

[0093] Specifically, the sliding frame 311 includes a vertical plate that is slidably matched with the Z-direction sliding groove and is arranged along the Z-axis direction, and a support plate installed on the vertical plate and used to install the TX clamping and fixing assembly 2; the abutment column 3132 is arranged on one side of the support plate close to the bracket 312;

[0094] The locking assembly 3134 includes a clamping plate installed on the outside of the side plate 3121 and provided with a waist-shaped hole, and a locking screw used in conjunction with the waist-shaped hole and located on the outside of the vertical plate; the waist-shaped hole is located on the outside of the clamping vertical plate and its long axis is set along the Z-axis direction.
