[0039] TWS true wireless Bluetooth headsets, that is, truly wireless Bluetooth headsets, use two wireless and independent Bluetooth headsets, and a charging case that can accommodate two headsets and charge the headsets will be provided. In the related art, during the production process of the charging case, it is necessary to perform performance tests on the charging case at multiple test workstations, and usually, a data cable is inserted into the charging interface of the charging bin for connection, which is very likely to scratch the charging interface of the charging case and affect the performance of the charging case.

[0040] To solve the above problems, the present application proposes a test carrier 1, which can be used to carry and connect a product under test 200 such as a charging case, so that the product under test 200 is connected to a test device 2 through the test carrier 1 for testing, thereby reducing the risk of damage to the test interface 210 of the product under test 200.

[0041] Please refer to Figure 1 、 Figure 2 and Figure 5 , in an embodiment of the present application, the test carrier 1 includes:

[0042] A base 11, the base 11 is provided with a mounting surface 111 for placing the product under test 200;

[0043] A connection structure 12, the connection structure 12 is arranged on the base 11, the connection structure 12 has a connection head 121 and a adapter 122, the connection head 121 and the adapter 122 are electrically connected, at least part of the connection head 121 protrudes from the mounting surface 111 for plugging and mating with the product under test 200, and the adapter 122 is used to connect to the test device 2.

[0044] The test vehicle 1 proposed in this application can be used in the test processes of different products such as charging boxes, earphones, and wearing devices according to actual needs. Specifically, the test vehicle 1 includes a base 11 and a connection structure 12 provided on the base 11. The base 11 can be in the form of a block, a plate, or other regular or irregular structures. An installation surface 111 for placing the product 200 to be tested is formed on the base 11. The connection structure 12 can be embedded in the base 11 or installed on the surface of the base 11; the connection structure 12 includes a connection head 121 and a adapter 122 that are electrically connected to each other. The connection head 121 and the adapter 122 can be connected by a wire or can be configured as a connection structure 12 such as a coaxial connector; among them, the connection head 121 protrudes from the installation surface 111 so that when the product 200 to be tested is placed on the installation surface 111, the connection head 121 is inserted into the test interface 210 of the product 200 to be tested. The adapter 122 of the connection structure 12 can be located outside the base 11 or can be housed inside the base 11 as in the following embodiments. Only an opening for exposing the adapter 122 needs to be provided on the surface of the base 11. The adapter 122 can be provided with connection contacts 1221 for abutting against the probe 221 type test connector 22 provided on the test device 2 to conduct electricity with each other; the adapter 122 and the test connector 22 provided on the test device 2 can also be configured as a male-female head structure that can be plugged and mated; in addition, it is defined that the base 11 has an installation surface 111, a bottom surface opposite to the installation surface 111, and a side surface located between the installation surface 111 and the bottom surface; the adapter 122 can be connected to the test device 2 from the bottom surface or can be connected to the test device 2 from the side surface, which is not limited herein.

[0045] When using the test vehicle 1 of this application to test the product 200 to be tested, the product 200 to be tested is placed on the installation surface 111 of the base 11, and the connection head 121 is inserted into the test interface 210 of the product 200 to be tested. Then, when the adapter 122 of the test vehicle 1 is electrically connected to the test connector 22 of the test device 2, the test device 2 can test the product 200 to be tested. After the product 200 to be tested is detected at the current test station, the test vehicle 1 loaded with the product 200 to be tested is disconnected from the test device 2 and transferred to the next test station to be connected to another test device 2; thus configured, when performing multi-station testing on the product 200 to be tested, the product 200 to be tested only needs to be plugged into the test vehicle 1 before testing and does not need to be removed from the test vehicle 1 during the entire test process, reducing the plugging and unplugging operations at the test interface 210 of the product 200 to be tested, reducing the risk of damage to the product test interface 210, and ensuring product performance.

[0046] Therefore, it can be understood that in the technical solution of the present application, the test vehicle 1 is used to place the charging box and the product 200 to be tested. When the product 200 to be tested is placed on the mounting surface 111 of the test vehicle 1, the connector 121 of the connection structure 12 in the test vehicle 1 is inserted into the charging interface or other test interfaces 210 of the product 200 to be tested; the product 200 to be tested can be electrically connected to the test device 2 through the test vehicle 1 to test the product 200 to be tested. After the test is completed, the test vehicle 1 with the product 200 to be tested is transferred to the next workstation for testing together. That is to say, in the technical solution of the present application, during the process of testing the product 200 to be tested, the product 200 to be tested only needs to be inserted and pulled out with the test vehicle 1 once, and there is no need to repeatedly insert and pull the data cable into the charging interface or other test interfaces 210 of the product 200 to be tested on multiple test workstations, reducing the risk of damage to the product test interface 210.

[0047] Please refer to Figure 1 、 Figure 3 and Figure 5 , in an embodiment, the mounting surface 111 is convexly provided with a limiting structure 13, the limiting structure 13 encloses a limiting space 132, the connector 121 is located in the limiting space 132, and the limiting space 132 is used to limit the product 200 to be tested.

[0048] In this embodiment, the limiting structure 13 can be an open-loop or closed-loop structure integrally provided along at least part of the circumference of the mounting surface 111, or can be composed of at least two limiting parts 131 in the following embodiments; and the connection structure 12 is located in the limiting space 132 enclosed by the limiting structure 13. In this setting method, when the product 200 to be tested is placed on the mounting surface 111, at least part of the product 200 to be tested is limited in the limiting space 132, which can improve the connection strength between the product 200 to be tested and the test vehicle 1, reduce the risk of the product 200 to be tested detaching from the test vehicle 1, and can use the limiting space 132 to guide the installation of the product 200 to be tested, facilitating the alignment and insertion between the test interface 210 of the product 200 to be tested and the connector 121. Among them, the limiting structure 13 can be made of at least one material such as plastic, metal, rubber, foam, etc., and the limiting structure 13 can be integrally formed with the base 11, or the limiting structure 13 can be detachably connected to the base 11.

[0049] Please refer to Figure 5 and Figure 7 , in an embodiment, the limiting structure 13 includes at least two limiting parts 131, and at least two of the limiting parts 131 are arranged at intervals along the circumference of the limiting space 132.

[0050] Among them, the limiting structure 13 may include two relatively arranged limiting portions 131, or may be provided with three or more limiting portions 131, and the shapes of the respective limiting portions 131 may be the same or different; among them, two adjacent limiting portions 131 are arranged at intervals, which can not only reduce the material use of the limiting structure 13, but also form an avoidance gap to facilitate the user to grab the product 200 to be measured from the gap position.

[0051] Please refer to Figure 7 , in an embodiment, the limiting structure 13 is detachably connected to the base 11. With such a setting, it is convenient to replace the limiting structures 13 of different shapes to form limiting spaces 132 with different contours to be applicable to products 200 to be measured of different shapes.

[0052] Combined with referring to Figure 7 and Figure 9 , in an embodiment, one of the first positioning holes 133 and the first positioning posts 112 is provided on the mounting surface 111, and the other of the first positioning holes 133 and the first positioning posts 112 is provided on the surface of the limiting structure 13 facing the mounting surface 111, and the first positioning post 112 is inserted into the first positioning hole 133.

[0053] In this embodiment, the limiting structure 13 and the base 11 are not an integral structure, and the base 11 is mounted on the mounting surface 111 of the base 11 in a detachable or non-detachable manner. Among them, the first positioning holes 133 may be provided at the bottom of the limiting structure 13, and the first positioning posts 112 are correspondingly provided on the mounting surface 111 of the base 11; or the first positioning posts 112 may be protruded at the bottom of the limiting structure 13, and the first positioning holes 133 are correspondingly opened on the mounting surface 111; with such a setting, when the limiting structure 13 needs to be mounted on the base 11, the first positioning posts 112 are inserted into the first positioning holes 133 to limit and position the mounting position of the limiting structure 13, ensuring that the formed limiting space 132 is adapted to the product 200 to be measured and can accommodate and limit the product 200 to be measured. Among them, the first positioning posts 112 may be cylindrical, prismatic or columnar structures of other shapes, and the shape of the first positioning holes 133 is adapted to the first positioning posts 112. When the first positioning posts 112 are cylindrical, at least two groups of first positioning posts 112 and first positioning holes 133 may be provided, or other positioning structures or locking structures may be provided to prevent the limiting structure 13 from rotating on the mounting surface 111.

[0054] In some embodiments, the limiting structure 13 includes at least two limiting portions 131, and each limiting portion 131 and the base 11 can be positioned and matched through at least one group of first positioning posts 112 and first positioning holes 133.

[0055] In an embodiment of the present application, at least one side of the limiting structure 13 facing the limiting space 132 is provided as an elastic structure.

[0056] In this embodiment, the entire limiting structure 13 can be made of an elastic material, such as soft polyurethane (PU) plastic or polyoxymethylene (POM) plastic, rubber, foam, latex, etc.; it can also be composed of a hard material and an elastic material attached to the inner side of the hard material. Making the surface of the limiting structure 13 facing the limiting space 132 relatively elastic and soft can avoid scratching the surface of the product 200 to be tested and reduce the risk of damage to the product 200 to be tested.

[0057] Please refer to Figures 5 to 8 , in an embodiment, the base 11 has a bottom surface opposite to the mounting surface 111, and the base 11 is provided with a connection hole 113 penetrating through the mounting surface 111 and the bottom surface; the connection structure 12 is inserted through the mounting hole, and the adapter 122 is exposed at one end of the connection hole 113 away from the mounting surface 111.

[0058] In this embodiment, the base 11 has a bottom surface and a mounting surface 111 opposite to each other, and a connection hole 113 penetrating through the mounting surface 111 and the bottom surface is provided on the base 11; the connection head 121 and the adapter 122 of the connection structure 12 are arranged in sequence along the axial direction of the connection hole 113, so that the connection structure 12 is inserted into the connection hole 113, the connection head 121 protrudes from the opening at one end of the connection hole 113 located on the mounting surface 111, and the adapter 122 is exposed at the opening at one end of the connection hole 113 located on the bottom surface. At least part of the adapter 122 can protrude from the connection hole 113 to the bottom surface, or the adapter 122 can be located inside the connection hole 113, so that the test connector 22 of the test device 2 is inserted into the connection hole 113 to be connected to the adapter 122. By arranging the connection head 121 and the adapter 122 at two coaxial ends, a bearing surface for carrying the test carrier 1 can be provided on the test device 2, and the bearing surface is provided with a test connector 22 for connecting to the adapter 122. In this way, when the test carrier 1 is placed on the bearing surface, the test connector 22 can be connected to the adapter 122, and when the test carrier 1 is removed after the test is completed, the test connector 22 and the adapter 122 are also disconnected at the same time, without the need to plug and unplug the test connector 22 in addition to the operation of taking and placing the test carrier 1, improving the test convenience.

[0059] Please refer to Figure 7 , in an embodiment, the connection structure 12 is further provided with at least one indicator light 123, and the indicator light 123 is used to indicate the connection state of at least one of the product 200 to be tested and the test device 2 with the connection structure 12.

[0060] In this embodiment, an indicator light 123 is further provided in the connection structure 12. The indicator light 123 is electrically connected to the connector 121 and the adapter 122. The indicator light 123 can be arranged outside the connection hole 113, or can be arranged inside the connection hole 113 as in the following embodiment and emit light outward through the light leakage hole 114; the indicator light 123 can be used to indicate the connection state between the product under test 200 and the connector 121, or can be used to indicate the connection state between the test device 2 and the adapter 122 of the test carrier 1. Taking the indicator light 123 indicating the connection state between the product under test 200 and the connector 121 as an example, the connection state between the product under test 200 and the connector 121 includes normal connection and abnormal connection. The normal and abnormal connection states can be respectively corresponding to the indicator light 123 being on or off, or the indicator light 123 can have different lighting effects, such as different lighting colors, different lighting durations (constant on or flashing), or at least two indicator lights 123 can be set to light different indicator lights 123 to respectively correspond to and prompt the two connection states of normal connection and abnormal connection; with such a setting, it is convenient for the operator to determine whether the product under test 200 is normally connected to the connector 121, and timely adjust the installation state of the product under test 200 and check the product under test 200 and the test carrier 1 when the connection is abnormal.

[0061] The method of using the indicator light 123 to indicate the connection state between the test device 2 and the adapter 122 of the test carrier 1 is substantially the same as the above-described embodiment of indicating the connection state between the product under test 200 and the connector 121, and will not be specifically described herein. It should be noted that the connection structure 12 can be provided with only one set of indicator lights 123 to indicate the connection state between the test device 2 and the adapter 122 of the test carrier 1, or to indicate the connection state between the product under test 200 and the connector 121. Two sets of indicator lights 123 can also be provided to respectively indicate the connection state between the test device 2 and the adapter 122 of the test carrier 1 and the connection state between the product under test 200 and the connector 121.

[0062] In some embodiments, only one set of indicator lights 123 can also be provided to indicate the connection state between the product under test 200 and the connector 121 and the connection state between the adapter 122 and the test device 2. For example, the indicator light 123 can emit red light and green light. When the product under test 200 is connected to the test carrier 1, if red light is emitted, it indicates an abnormal connection, and if green light is emitted, it indicates a normal connection; after confirming that the product under test 200 is normally connected to the test carrier 1, the test carrier 1 with the product under test 200 installed needs to be connected to the test device 2. If the test carrier 1 is normally connected to the test device 2, the indicator light 123 still emits green light. If the test carrier 1 is abnormally connected to the test device 2, the indicator light 123 changes to red light.

[0063] In some embodiments, different lighting effects of the indicator light 123 can respectively correspond to the connection states between the product under test 200 and the connector 121, as well as the connection states between the adapter 122 and the test device 2. For example, two connection states of normal connection and abnormal connection between the product under test 200 and the connector 121 are indicated by different lighting colors, and two connection states of normal connection and abnormal connection between the adapter 122 and the test device 2 are indicated by different lighting durations (constant on or flashing).

[0064] Please refer to Figure 7 , in one embodiment, the indicator light 123 is located within the connection hole 113, and a light leakage hole 114 penetrating through to the side wall of the connection hole 113 is formed on the surface of the base 11, and the indicator light 123 is arranged facing the light leakage hole 114.

[0065] In this embodiment, the indicator light 123 is arranged on the side wall of the connection structure 12, so that the connector 121, the adapter 122, and the indicator light 123 in the connection structure 12 are integrated into an integral structure, facilitating the overall disassembly and assembly of the connection structure 12. The connection structure 12 is inserted into the connection hole 113 of the base 11, such that the indicator light 123 is received within the connection hole 113 and is disposed opposite to the light leakage hole 114 penetrating through to the surface of the base 11 on the side wall of the connection hole 113; this arrangement can protect the indicator light 123, and the setting of the light leakage hole 114 does not affect the operator's observation of the light emission of the indicator light 123.

[0066] Please refer to Figures 5 to 7 , in one embodiment, the test carrier 1 further includes a stopper 14, the stopper 14 is located on one side of the mounting surface 111 and covers the mounting hole, the stopper 14 is provided with an avoidance hole 141, a limiting step 124 facing the connector 121 is provided on the side of the connection structure 12, the connector 121 passes through the avoidance hole 141, and the limiting step 124 abuts against the stopper 14.

[0067] In this embodiment, the test carrier 1 is provided with a stopper 14, the stopper 14 covers the opening of the connection hole 113 on the side of the mounting surface 111 and is connected to the base 11. When the connection structure 12 is inserted into the connection hole 113, the connector 121 passes through the avoidance hole 141 of the stopper 14 to protrude from the mounting surface 111, and the limiting step 124 of the connection structure 12 abuts against the stopper 14 to limit the connection structure 12, so as to limit the height of the connector 121 protruding from the mounting surface 111, and prevent the connector 121 from protruding too high and causing the product under test 200 to be unable to be carried on the mounting surface 111 after being inserted and matched with the connector 121.

[0068] Combined with reference to Figure 5 andFigure 7 , in one embodiment, a counterbore 115 is formed in the mounting surface 111, the connecting hole 113 penetrates through the bottom wall of the counterbore 115, and the stopper 14 is located in the counterbore 115.

[0069] In this embodiment, a counterbore 115 is formed in the mounting surface 111. The counterbore 115 is located outside the connecting hole 113. The stopper 14 can be installed in the counterbore 115, which can not only limit the stopper 14 but also prevent the stopper 14 from protruding from the mounting surface 111, so as to ensure that the product under test 200 can directly contact and be placed on the mounting surface 111, improving the stability of the product under test 200 placed on the base 11.
