[0035] This embodiment discloses an electronic test device, such as a head-mounted earphone test device, including a special-shaped wheel groove motion mechanism. Please refer to Figure 1 and Figure 2, the special-shaped wheel groove motion mechanism includes a base plate 100, a first groove plate 200, a first bracket 300, and a first swing arm 400. The base plate 100 is installed with a first slide rail 110, and the length of the first slide rail 110 extends along the first direction. As shown in the figure, the first direction is indicated as the X-axis direction, that is, the front-back direction. The first groove plate 200 is connected to the base plate 100, and a first guiding groove 201 is provided on the first groove plate 200. The first bracket 300 is slidably installed on the first slide rail 110, and a second slide rail 310 is provided on the first bracket 300. The length of the second slide rail 310 extends along the second direction, and the second direction is perpendicular to the first direction. As shown in the figure, the second direction is indicated as the Z-axis direction, that is, the up-down direction. A first slider 320 is slidably installed on the second slide rail 310. The first swing arm 400 is provided with a first guiding member 410, and the first guiding member 410 is movably installed in the first guiding groove 201. The first swing arm 400 is rotatably connected to the first slider 320, and a first assembly end 401 is provided on the first swing arm 400.
[0036] During use, the power source acts on the first bracket 300, that is, the first bracket 300 is used as the driving part. When the first bracket 300 is driven to move along the first slide rail 110, the first bracket 300 drives the first swing arm 400 to move in the first direction. At the same time, the first bracket 300 enables the first swing arm 400 to move in the second direction through the cooperation of the second slide rail 310 and the first slider 320. During the movement, the position difference between the relative two ends of the first guiding member 410 in the first guiding groove 201 causes the first swing arm 400 to rotate relative to the first slider 320, so that the first assembly end 401 of the first swing arm 400 moves and rotates around the axis in the first direction and the second direction to cope with complex compound motion scenarios and simplify the mechanism, realizing miniaturized design.
[0037] Among them, the first guiding groove 201 is a special-shaped guiding groove. Compared with the conventional straight guiding groove, the structure of the special-shaped guiding groove can be designed according to the actual motion trajectory and can cope with complex compound motion scenarios. Exemplarily, the first distance of the first guiding groove 201 is less than the second distance of the first guiding groove 201. The first distance is used to represent the distance between the first end of the first guiding groove 201 and the base plate 100 in the second direction, and the second distance is used to represent the distance between the second end of the first guiding groove 201 and the base plate 100 in the second direction. As shown in the figure, an X-Z coordinate system is established with the marked position O in the figure as the coordinate origin. The overall shape of the first guiding groove 201 is similar to an arc, and the X-axis coordinate of the first end of the first guiding groove 201 is greater than the X-axis coordinate of the second end, and the Z-axis coordinate of the first end of the first guiding groove 201 is less than the Z-axis coordinate of the second end to realize the guiding of the first swing arm 400 in the X-axis direction and the Z-axis direction.
[0038] Please refer to Figure 1The first guide member 410 includes a first roller 411 and a second roller 412, which are arranged adjacent to each other and are both installed in the first guide groove 201. Assume that the first end of the first swing arm 400 is connected to the first slider 320, and the second end of the first swing arm 400 is provided with the first roller 411 and the second roller 412. When the first roller 411 and the second roller 412 move in the first guide groove 201, since the first roller 411 and the second roller 412 have a position difference, in the first guide groove 201, the relative position of the first roller 411 is higher than the relative position of the second roller 412, and the second end of the first swing arm 400 can be rotated relative to the first end during the movement, thereby realizing the rotation around the axis, and then the first assembly end 401 on the first swing arm 400 can be rotated around the axis.
[0039] Please refer to Figure 1 or Figure 2 A first position sensor 330 is provided adjacent to the first slide rail 110 and on the moving track of the first bracket 300. The moving position of the first bracket 300 can be detected by the first position sensor 330, thereby achieving accurate positioning of the motion track.
[0040] Please refer to Figure 2 or Figure 3 The substrate 100 is also provided with a third slide rail 120 parallel to the first slide rail 110 and a driving member 130 installed. For example, the driving member 130 is a motor. The driving member 130 is installed at the bottom of the substrate 100, which can leave enough space for the upper surface of the substrate 100. Please refer to Figure 1 and Figure 2 The special-shaped wheel groove motion mechanism also includes a second groove plate 500, a second bracket 600 and a second swing arm 700. The second groove plate 500 is connected to the base plate 100. The second groove plate 500 is provided with a second guide groove 501. The second bracket 600 is slidably installed on the third slide rail 120. A connecting plate 140 is connected between the second bracket 600 and the first bracket 300. The connecting plate 140 is transmission-connected to the driving member 130, for example, the connecting plate 140 is connected to the motor through a belt. A fourth slide rail 610 parallel to the second slide rail 310 is provided on the second bracket 600. A second slider 620 is slidably installed on the fourth slide rail 610. The second swing arm 700 is provided with a second guide member 710. The second guide member 710 is movably installed in the second guide groove 501. The second swing arm 700 is rotationally connected to the second slider 620, and a second assembly end 701 is provided on the second swing arm 700.
[0041] In use, the driving member 130 drives the connecting plate 140 to move in the first direction. The connecting plate 140 drives the first bracket 300 and the second bracket 600 to move along the first slide rail 110 and the third slide rail 120 respectively, thereby driving the first swing arm 400 and the second swing arm 700 to achieve X-axis, Z-axis, and R-axis (rotation about the axis) movements. The movement principle of the second swing arm 700 is the same as that of the first swing arm 400, and thus will not be elaborated here.
[0042] The structure of the second guiding groove 501 is the same as that of the first guiding groove 201, and the structure of the second guiding member 710 is the same as that of the first guiding member 410. For example, the second guiding member 710 includes a third roller 711 and a fourth roller 712, so that the synchronous movement of the first swing arm 400 and the second swing arm 700 can be achieved.
[0043] A second position sensor is provided adjacent to the third slide rail 120 and on the movement trajectory of the second bracket 600. Alternatively, a third position sensor is provided on the substrate 100 and on the movement trajectory of the connecting plate 140. Precise positioning of the movement trajectory can be achieved through the second position sensor or the third position sensor.
[0044] Please refer to Figure 3 and Figure 4 , as one of the mechanisms of the electronic product testing equipment, in application, an assembly plate 800 is installed at the first assembly end 401 of the first swing arm 400 and the second assembly end 701 of the second swing arm 700, and corresponding product fixtures are installed on the assembly plate 800. When conducting product testing, the special-shaped wheel groove movement mechanism is used in pairs. The earcups on the opposite sides of the product (such as a head-mounted earphone) are placed on the corresponding fixtures. By realizing the X-axis, Z-axis, and R-axis movements of the assembly plate 800 through the special-shaped wheel groove movement mechanism, the earcups on the opposite sides of the head-mounted earphone can be pulled to simulate the actions of a user putting on or taking off the product, thereby testing the performance of the product.
[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
