Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0039] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings:

[0040] refer to Figure 1 and Figure 2According to the transmission device of the first aspect embodiment of the present application, the transmission device includes a connecting structure 300, a carrier 210, a first bracket 100 and a second bracket 200. The first bracket 100 is connected to the second bracket 200. The first bracket 100 and the second bracket 200 jointly enclose a first cavity 110 and a second cavity 120 that are connected. The first cavity 110 is provided with a first opening 111 along a first direction for the male connector 350 to be inserted into the first cavity 110 along the first direction. The connection structure 300 includes a plug female connector 310, a fixing portion 320 and a connecting portion 330. The fixing portion 320 and the plug female connector 310 are both located in the first cavity 110. Along the first direction, the plug female connector 310 is located on a side of the fixing portion 320 close to the first opening 111 and connected to the fixing portion 320. The connecting portion 330 is located in the second cavity 120 and connected to a side of the fixing portion 320 away from the first opening 111. The inner wall of the first cavity 110 abuts against the fixing portion 320 to fix the fixing portion 320. The entire connection structure 300 has a determined position in the first cavity 110, and there is a gap 113 between the female connector 310 and the inner wall of the first cavity 110, and the gap 113 is suitable for the male connector 350 to be inserted into the first cavity 110. The supporting member 210 is located between the second bracket 200 and the connecting portion 330, and the connecting portion 330 is used to connect with the FPC 340. The second bracket 200 abuts against the supporting member 210, so that the first bracket 100 and the supporting member 210 are used to jointly abut and fix the FPC 340.

[0041] Therefore, the abutment and fixation of the fixing part 320 by the first bracket 100 and the second bracket 200 improves the reliability of the plug-in fit between the plug-in male connector 350 and the plug-in female connector 310. The first bracket 100 and the carrier 210 also jointly abut and fix the FPC 340 to fill the gap between the connecting part 330 and the second bracket 200, effectively avoiding the unstable connection between the connecting part 330 and the FPC 340 caused by frequent charging and plugging, and further increasing the reliability of the transmission device.

[0042] It should be noted that the transmission device can be used for charging, data transmission, etc., and the male plug 350 and the female plug 310 can be male and female plugs of the Type-c interface type.

[0043] In other embodiments, the transmission device includes a carrier 210, which is located between the connecting portion 330 and the second bracket 200. The connecting portion 330 is connected to an FPC 340 on the side facing the carrier 210. The connecting portion 330 is connected to the FPC 340, and the carrier 210 supports the FPC 340. The connecting portion 330 and the carrier 210 are used to jointly fix the FPC 340. It should be understood that the plug-in female head 310 will generate certain vibrations when plugging with the plug-in male head 350, and the vibrations will be transmitted to the connecting portion 330 along the fixing portion 320, affecting the connection stability between the connecting portion 330 and the FPC 340. The carrier 210 is provided to support the FPC 340 connected to the connecting portion 330, thereby reducing the vibration impact generated when the plug-in female head 310 and the plug-in male head 350 are plugged together, effectively ensuring the stability of the connection between the connecting portion 330 and the FPC 340, and the transmission device can transmit more stably.

[0044] refer to Figures 1 to 3 In some embodiments, a positioning column 220 is provided on the second bracket 200, and a fixing hole 211 is provided on the carrier 210. The positioning column 220 is penetrated in the fixing hole 211 to realize the connection between the carrier 210 and the second bracket 200. It should be noted that the number of the positioning columns 220 can be multiple. Taking the second bracket 200 as an example where two positioning columns 220 are provided, two fixing holes 211 are correspondingly provided on the carrier 210, and each fixing hole 211 is penetrated by a positioning column 220, thereby limiting the rotation of the carrier 210 around the axis of the positioning column 220 relative to the second bracket 200, so as to better support the FPC340 connected to the connecting portion 330 and ensure the stability of the connection between the connecting portion 330 and the FPC340.

[0045] refer to Figure 1 and Figure 2In some embodiments, the transmission device further includes a third bracket 400, the third bracket 400 defines a third cavity 410, the inner wall of the third cavity 410 is provided with a first groove 411 and a second groove 412, the outer wall of the first bracket 100 is provided with a first protrusion 130, and the outer wall of the second bracket 200 is provided with a second protrusion 140. After the first bracket 100 and the second bracket 200 are connected, the third cavity 410 is configured to accommodate the first bracket 100 and the second bracket 200. When the first bracket 100 and the second bracket 200 are in the third cavity 410, the first protrusion 130 is stuck The first bracket 100 and the second bracket 200 are inserted into the first groove 411, and the second protrusion 140 is stuck into the second groove 412 to limit the first bracket 100 and the second bracket 200 from being separated from the third cavity 410. The inner wall of the third cavity 410 also supports the first bracket 100 and the second bracket 200, further increasing the stability of the connection between the first bracket 100 and the second bracket 200. The more stable the connection between the first bracket 100 and the second bracket 200 is, the less likely the connection structure 300 is to shake, and the connection between the connecting part 330 and the FPC 340 is more stable, further improving the transmission reliability of the transmission device.

[0046] refer to Figures 1 to 4 In some embodiments, a plurality of positioning holes 150 are provided on the first bracket 100, and a plurality of positioning posts 220 are provided on the second bracket 200. When the first bracket 100 is connected to the second bracket 200, the positions of the positioning posts 220 and the positioning holes 150 correspond to each other, and the positioning posts 220 are inserted into the positioning holes 150 one by one, that is, the number of the positioning posts 220 and the positioning holes 150 is the same, and each positioning hole 150 is inserted with a positioning post 220. The arrangement of the positioning holes 150 and the positioning posts 220 enables the first bracket 100 and the second bracket 200 to be connected along the direction of the axis of the positioning posts 220, and can also limit the relative rotation of the first bracket 100 and the second bracket 200 around the axis of the positioning posts 220, thereby ensuring the stable support of the inner wall of the first cavity 110 against the fixing portion 320, and the first bracket 100 and the second bracket 200 jointly clamp and fix the FPC 340, which is beneficial to ensuring the transmission stability of the transmission device.

[0047] In other embodiments, the first bracket 100 is provided with a plurality of positioning holes 150, the second bracket 200 is provided with a plurality of positioning posts 220, the connecting portion 330 is placed in the first cavity 110, a carrier 210 is provided between the connecting portion 330 and the second bracket 200, a plurality of fixing holes 211 are provided on the carrier 210, the positioning posts 220 first penetrate into the fixing holes 211, and then pass out from the fixing holes 211, and the part of the positioning posts 220 that passes out from the fixing holes 211 then penetrates into the positioning holes 150. It should be noted that the FPC 340 is connected to the connecting portion 330, and in order to fix the carrier 210 against the FPC 340, the FPC 340 is arranged between the carrier 210 and the connecting portion. Therefore, a position corresponding to the positioning posts 220 on the FPC 340 is provided with an avoidance structure to avoid the positioning posts 220. The first bracket 100 is connected to the second bracket 200. At the location of the second cavity 120, the first bracket 100 abuts against the FPC 340 at the side where the FPC 340 is connected to the connecting portion 330, and the carrier 210 abuts against the FPC 340 at the other side opposite to the FPC 340. The first bracket 100 and the carrier 210 jointly fix the FPC 340, and the carrier 210 is connected to the second bracket 200. The first bracket 100 and the second bracket 200 jointly clamp the FPC 340. It should be understood that the second bracket 200 and the first bracket 100 jointly clamp the FPC 340 through the carrier 210. This is beneficial to ensure that the electrical connection between the connecting portion 330 and the FPC 340 is stable.

[0048] refer to Figures 1 to 4 In some embodiments, a third protrusion 112 is provided on the inner wall of the first cavity 110, and the third protrusion 112 protrudes from the inner wall of the first cavity 110 toward the plug female connector 310. There is also a gap 113 between the third protrusion 112 and the plug female connector 310. When the plug male connector 350 is plugged into the plug female connector 310 in the first cavity 110, the third protrusion 112 is used to abut against the outer wall of the plug male connector 350. Compared with not providing the third protrusion 112, the contact area between the inner wall of the first bracket 100 and / or the second bracket 200 and the outer wall of the plug male connector 350 is reduced.

[0049] It should be noted that when the male connector 350 is mated with the female connector 310, the gap 113 between the inner wall of the first cavity 110 and the female connector 310 is used to limit the position of the male connector 350, thereby limiting the movement of the male connector 350 in the first cavity 110 in directions other than the first direction. To ensure that the male connector 350 can be smoothly inserted into the first cavity 110 along the first direction, the gap 113 between the inner wall of the first cavity 110 and the female connector 310 should be larger than the size of the male connector 350, that is, the male connector 350 is not inserted into the first cavity 110. After the male connector 350 is plugged into the female connector 310, there is a small distance between the outer wall of the male connector 350 and the inner wall of the first cavity 110. The smaller the distance is, the less likely the male connector 350 is to shake when plugged into the female connector 310, but the male connector 350 is less likely to be inserted into the first cavity 110. Therefore, when the male connector 350 is plugged into the female connector 310, a suitable distance should be maintained between the outer wall of the male connector 350 and the inner wall of the first cavity 110 to obtain a smoother plugging and unplugging experience.

[0050] Compared with reducing the size of the first cavity 110, by setting the third protrusion 112 on the inner wall of the first cavity 110, when the plug-in male connector 350 is inserted into the first cavity 110 along the first direction, the plug-in male connector 350 will not generate friction with the inner wall of the first cavity 110, but will generate friction with the third protrusion 112, thereby minimizing the contact area between the outer wall of the plug-in male connector 350 and the outer wall when the plug-in male connector 350 is inserted into the first cavity 110 along the first direction, thereby facilitating a smoother plug-in mating of the plug-in male connector 350 with the plug-in female connector 310.

[0051] refer to Figures 1 to 5 In some embodiments, the third protrusion 112 on the inner wall of the first cavity 110 is provided with a first guide slope 1121 on the side facing the female connector 310, and along the direction of the female connector 310 toward the fixing portion 320, that is, the direction in which the male connector 350 is inserted into the first cavity 110, the third protrusion 112 gradually approaches the female connector 310. Specifically, when the plug-in male connector 350 is inserted into the first cavity 110, the outer wall of the plug-in male connector 350 is guided by the first guide slope 1121, which facilitates the insertion of the plug-in male connector 350 into the first cavity 110. As the plug-in male connector 350 is inserted into the first cavity 110, the distance between the third protrusion 112 and the outer wall of the plug-in male connector 350 gradually decreases to limit the shaking of the plug-in male connector 350 in the first cavity 110, thereby ensuring the connection stability between the plug-in male connector 350 and the plug-in female connector 310. In addition, the stability of the plug-in female connector 310 can also ensure the stability of the connection between the connecting part 330 and the FPC 340, which is beneficial to make the transmission device more reliable.

[0052] refer to Figures 1 to 4In some embodiments, the first bracket 100 includes a supporting surface 160 that is supported by the second bracket 200, and a clamping portion 170 is provided on the supporting surface 160. The clamping portion 170 protrudes outward from the supporting surface 160. Along the first direction, the clamping portion 170 is located on a side of the first bracket 100 close to the first opening 111. A clamping groove 230 is provided on the second bracket 200, and the clamping groove 230 is located on a side of the second bracket 200 close to the first opening 111. The clamping portion 170 is used to be clamped into the clamping groove 230 to connect the first bracket 100 with the second bracket 200. The first bracket 100 and the second bracket 200 can be clamped with each other through the cooperation of the clamping portion 170 and the clamping groove 230. After the clamping portion 170 is clamped into the clamping groove 230, the clamping groove 230 restricts the clamping portion 170 from detaching from the clamping groove 230, and the connection between the first bracket 100 and the second bracket 200 is more stably.

[0053] refer to Figure 4 In some embodiments, at least one of the clamping groove 230 and the clamping portion 170 is provided with a second guide slope 231, and the second guide slope 231 is inclined relative to the direction in which the first bracket 100 and the second bracket 200 are clamped to each other. The second guide slope 231 is used to guide when the first bracket 100 and the second bracket 200 are clamped to facilitate smooth clamping between the first bracket 100 and the second bracket 200.

[0054] Specifically, in some embodiments, a second guiding slope 231 is provided on the groove wall of the snap-in groove 230, and the second guiding slope 231 is inclined relative to the direction in which the first bracket 100 and the second bracket 200 are snapped together. When the snap-in portion 170 is snapped with the snap-in groove 230, the snap-in portion 170 resists the second guiding slope 231, and the snap-in portion 170 is snapped with the snap-in groove 230 under the guidance of the second guiding slope 231, so as to facilitate the smooth connection between the first bracket 100 and the second bracket 200.

[0055] In other embodiments, a second guide bevel 231 is provided on the clamping portion 170, and the second guide bevel 231 is inclined relative to the direction in which the first bracket 100 and the second bracket 200 are clamped to each other. When the clamping portion 170 is clamped with the clamping groove 230, the groove wall of the clamping groove 230 resists the second guide bevel 231 and can move along the second guide bevel 231 relative to the first bracket 100, so that the clamping portion 170 and the clamping groove 230 cooperate and clamp with each other, thereby facilitating a smooth connection between the first bracket 100 and the second bracket 200.

[0056] In some embodiments, a second guiding bevel 231 is provided on both the snap-in groove 230 and the snap-in portion 170, and the second guiding bevel 231 on the snap-in groove 230 and the snap-in portion 170 are inclined relative to the direction in which the first bracket 100 and the second bracket 200 are snap-in to each other, and the second guiding bevel 231 provided on the snap-in groove 230 and the snap-in portion 170 are parallel to each other, so as to more smoothly realize the snap-in connection between the snap-in groove 230 and the snap-in portion 170, and ensure the smooth connection between the first bracket 100 and the second bracket 200.

[0057] It should be noted that the clamping portion 170 in any of the above embodiments can produce elastic deformation to achieve clamping with the clamping groove 230. After the clamping portion 170 is clamped with the clamping groove 230, the groove wall of the clamping groove 230 can limit the clamping portion 170 from detaching from the clamping groove 230 to ensure the stability of the connection between the first bracket 100 and the second bracket 200.

[0058] refer to Figure 3 and Figure 4 In some embodiments, the first cavity 110 includes an inner circumferential wall 114 arranged parallel to the first direction, one of the inner circumferential wall 114 and the fixing portion 320 is provided with a protrusion structure 115, and the other is provided with a groove structure 116. Along the first direction, the protrusion structure 115 and the groove structure 116 are located in the first cavity 110, and the protrusion structure 115 is used to be placed in the groove structure 116 to limit the movement of the fixing portion 320 along the first direction. The fixing portion 320 is also supported by the inner circumferential wall 114, which further increases the stability of the fixing portion 320 in the first cavity 110.

Both the plug-in female connector 310 and the connecting part 330 are connected to the fixing part 320, and limiting the relative movement of the fixing part 320 in the first cavity 110 along the first direction is equivalent to limiting the relative movement of the connection structure 300 in the first cavity 110 along the first direction, which is beneficial to ensuring the reliability of the transmission device.

[0060] In other embodiments, a groove structure 116 is provided on the inner wall 114, and a protrusion structure 115 is provided on the fixing portion 320. The protrusion structure 115 and the groove structure 116 should be able to cooperate with each other. After the first bracket 100 is connected to the second bracket 200, the protrusion structure 115 should be inserted into the groove structure 116 to limit the movement of the fixing portion 320 along the first direction in the first cavity 110. Similarly, the mutual cooperation between the protrusion structure 115 and the groove structure 116 is used to limit the movement of the connecting structure 300 along the first direction in the first cavity 110, so as to ensure the reliability of multiple insertions of the transmission device.

[0061] In other embodiments, a protrusion structure 115 and a groove structure 116 are provided on the inner circumferential wall 114, and a protrusion structure 115 and a groove structure 116 are also provided on the fixing part 320.
