[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0028] like Figure 1-5 As shown, this embodiment relates to a connection system. The connection system is used to connect a first device and a second device. The connection system includes a first housing 10 and a bracket 20. The first housing 10 is configured to form a first receiving cavity 13. The first device is assembled into the first receiving cavity 13 along a first direction x, exposing its first display area. One end of the bracket 20 is detachably connected to the side of the first housing 10 opposite to the first device. The second device is assembled into the other end of the bracket 20 along the first direction x, exposing its second display area. The bracket 20 extends at least partially along a second direction y, where the first direction x is perpendicular to the second direction y, such that both the first and second display areas are simultaneously exposed.

[0029] It should be further noted that the first housing 10 includes a first body 11 and a first extension 12. The first extension 12 is disposed around the first body 11 and extends in the opposite direction to the first direction x, such that the first body 11 and the first extension 12 form a first receiving cavity 13. One end of the bracket 20 is connected to the side of the first body 11 facing away from the first device, or to the side of the first extension 12 facing away from the first device. Preferably, the bracket 20 is connected to the side of the first body 11 facing away from the first device. The bracket 20 can be in the shape of a "7", an arc, or a "Z", etc. The bracket 20 extends at least partially along the second direction y, which is perpendicular to the first direction x, so that the second device can extend out from the back of the second device and expose the second display area, so as to simultaneously observe the first display area and the second display area.

[0030] Specifically, the first extension 12 has a clearance hole 121 to avoid the heat dissipation holes, charging holes, card slots, and buttons of the first device, allowing the first device to be used normally. The first extension 12 covers the edge of the first device away from the first housing 10 to assemble the first device into the first housing 10. The first body 11 includes a mounting member 111 and a protective member 112. The protective member 112 is disposed on the outer edge of the mounting member 111 and is connected to the first extension 12. The side of the mounting member facing away from the first device is detachably connected to one end of the bracket 20. The hardness of the mounting member 111 is greater than that of the protective member 112, thereby ensuring both the user's grip comfort and the connection strength between the bracket 20 and the first housing 10.

[0031] In this embodiment, the bracket 20 is connected to the side of the first body 11 facing away from the first device. The second direction y can be any direction perpendicular to the first direction x. Preferably, the second direction y is an upward or downward direction. More preferably, the second direction y is a vertically upward direction.

[0032] In other embodiments, the bracket 20 is connected to the side of the first extension 12 facing away from the first device, and the second direction y should be the direction in which the first extension 12 faces away from the first device.

[0033] like Figure 1-5 As shown, the first housing 10 includes a first body 11 and a first connecting unit 1111. The first body 11 is configured to form a first receiving cavity 13. The first connecting unit 1111 is disposed on the side of the first body 11 facing away from the first device, and extends at least partially along the first direction x.

[0034] The support 20 includes an adsorption unit 23, a support unit 21, and a second connecting unit 22, wherein the adsorption unit 23 is used to adsorb the second device. The support unit 21 extends at least partially along the second direction y, one end of the support unit 21 is connected to the adsorption unit 23, and the other end of the support unit 21 is detachably connected to the first connecting unit 1111. The second connecting unit 22 is connected to the end of the support unit 21 away from the adsorption unit 23, and the second connecting unit 22 is detachably connected to the first connecting unit 1111.

[0035] Specifically, the adsorption unit 23 is rotatably connected to the support unit 21, and the posture of the second device can be adjusted by rotating the adsorption unit 23 so that the user can observe the second display area.

[0036] like Figure 1-3 and Figure 5 As shown, in this embodiment, the adsorption unit 23 and the support unit 21 are hinged together by a first rotating shaft 24. The length direction of the first rotating shaft 24 is consistent with a third direction, which is perpendicular to the first direction x and the second direction y. The posture of the second device can be adjusted by rotating the adsorption unit 23 to facilitate observation of the second display area.

[0037] Specifically, the support unit 21 includes a third body 211 and a third connecting portion 212. The third body 211 extends at least partially along the second direction y. The third connecting portion 212 is disposed at one end of the third body 211 near the adsorption unit 23, and the third connecting portion 212 has a first shaft hole 2122, which is disposed along the third direction.

[0038] The adsorption unit 23 includes an adsorption section 231 and a fourth connecting section 232. One side of the adsorption section 231 is used to adsorb the second device. The fourth connecting section 232 is located on the side of the adsorption section 231 facing away from the second device, and the fourth connecting section 232 has a second shaft hole 2321, which is arranged along a third direction. Both the first shaft hole 2122 and the second shaft hole 2321 are used for assembling a first rotating shaft 24, so that the adsorption unit 23 and the support unit 21 are hinged together via the first rotating shaft 24.

[0039] Specifically, the third connecting part 212 includes two connecting legs, which are spaced apart along a third direction to form a relief groove 2123 together with the third body 211. The relief groove 2123 is used for the fourth connecting part 232 to be inserted so that the second shaft hole 2321 is aligned with the first shaft hole 2122.

[0040] More specifically, the adsorption part 231 includes a fifth body 2311, a cover plate 2312, and a magnetic component 2313. The fifth body 2311 and the cover plate 2312 form a receiving space 2314 for receiving the magnetic component 2313. The fourth connecting part 232 includes a screw hole 2322. In this embodiment, the screw hole 2322 is a blind hole and is arranged along the first direction x. The fifth body 2311 has a third through hole 23111, which is arranged along the first direction x and communicates with the screw hole 2322. A screw 233 is inserted from the receiving space 2314 along the first direction x into the third through hole 23111 and the screw hole 2322 to fix the fourth connecting part 232 and the adsorption part 231.

[0041] In other embodiments, the adsorption section 231 is a component of a second adsorption device such as a suction cup.

[0042] like Figure 5 As shown, in this embodiment, a damping sleeve is provided between the first rotating shaft 24 and the first shaft hole 2122, or a damping sleeve is provided between the first rotating shaft 24 and the second shaft hole 2321, so as to fix the posture of the second device after the adsorption unit 23 rotates.

[0043] In other implementations, the first rotating shaft 24 is a damping shaft, which facilitates fixing the posture of the second device after the adsorption unit 23 rotates.

[0044] like Figure 1-3 and Figure 5 As shown, preferably, the dimension of the third connecting portion 212 in the first direction x is greater than the dimension of the third main body 211 in the first direction x. That is, the thickness of the third connecting portion 212 is greater than the thickness of the third main body 211, thereby ensuring the strength when the third connecting portion 212 and the fourth connecting portion 232 are hinged, while reducing the overall weight of the bracket 20.

[0045] like Figure 1-3 and Figure 5 As shown, the third connecting portion 212 extends at least partially in the opposite direction to the first direction x, so that the second device extends in the opposite direction to the first direction x, making the first display area flush with the second display area, or the second display area extends out of the plane where the first display area is located, so that the second display area is closer to the user and makes it easier for the user to observe the first display area and the second display area at the same time.

[0046] like Figure 1-5 As shown, the first connecting unit 1111 includes a first connecting portion 11111 and a first snap-fit ​​portion 11112. The first connecting portion 11111 is disposed on the side of the first main body 11 facing away from the first device and extends along the first direction x. The first snap-fit ​​portion 11112 is disposed at the end of the first connecting portion 11111 away from the first main body 11 and extends along the second direction y and the opposite direction of the second direction y.

[0047] The second connecting unit 22 includes a fourth main body 221, a second connecting portion 223, and two second snap-fit ​​portions 226. The fourth main body 221 is connected to the end of the support unit 21 away from the adsorption unit 23. The second connecting portion 223 is located on the side of the fourth main body 221 facing the first connecting unit 1111 and extends towards the first connecting unit 1111. The second connecting portion 223 has a connecting groove 222 for the first connecting portion 11111 and the first snap-fit ​​portion 11112 to be inserted in a third direction. Both second snap-fit ​​portions 226 are located at the end of the second connecting portion 223 facing the first connecting unit 1111, and are respectively located on the two walls of the connecting groove 222, extending towards each other. The two second snap-fit ​​portions 226 are spaced apart to accommodate the passage of the first connecting portion 11111. The first connecting portion 11111 and the second connecting portion 223 are interference-fitted.

[0048] Specifically, the two second latching portions 226 cooperate with the first latching portion 11112 to limit the relative displacement of the first connecting unit 1111 and the second connecting unit 22 in the first direction x. The two second latching portions 226 cooperate with the first connecting portion 11111, and the first latching portion 11112 cooperates with the second connecting portion 223 to limit the relative displacement of the first connecting unit 1111 and the second connecting unit 22 in the second direction y. The first connecting portion 11111 and the second connecting portion 223 are interference-fitted, as are the first latching portions 11112 and the second connecting portion 223, and the two second latching portions 226 and the first connecting portion 11111 to limit the relative displacement of the first connecting unit 1111 and the second connecting unit 22 in the third direction. Through the above arrangement, the first housing 10 and the bracket 20 are securely assembled.

[0049] In other embodiments, the second connecting unit 22 and the first connecting unit 1111 are fastened and detachably connected by means of snap-fit ​​or other means.

[0050] like Figure 1-3 and Figure 5 As shown, in the direction away from the connecting groove 222, the second connecting portion 223 gradually increases in size in the third direction to form a third guide slope 224, which facilitates the first connecting unit 1111 to be embedded in the connecting groove 222.

[0051] like Figure 1-3 and Figure 5As shown, in the direction away from the connecting groove 222, the second snap-fit ​​portion 226 gradually increases in size in the third direction to form a fourth guide slope 225, which facilitates the first connecting unit 1111 to be embedded in the connecting groove 222. The direction away from the connecting groove 222 of the second snap-fit ​​portion 226 is the opposite direction to the first direction x.

[0052] Specifically, when the bracket 20 is assembled with the first housing 10, the first connecting unit 1111 needs to be embedded in the connecting groove 222. Since the first connecting unit 1111 is an interference fit with the second connecting unit 22, and the size of the first connecting unit 1111 is slightly larger than the size of the connecting groove 222, the first connecting unit 1111 needs to be deformed before being embedded in the connecting groove 222. Without the third guide slope 224 and the fourth guide slope 225, the first connecting unit 1111 needs to be squeezed to make its size smaller than the size of the connecting groove 222 before assembling the first connecting unit 1111 with the second connecting unit 22, making the assembly of the first connecting unit 1111 and the second connecting unit 22 difficult.

[0053] By setting the third guide slope 224 and the fourth guide slope 225, a guide space is formed outside the connecting groove 222. The size of the guide space is slightly larger than the size of the first connecting unit 1111. During the assembly of the first connecting unit 1111 and the second connecting unit 22, the third guide slope 224 and the fourth guide slope 225 guide the deformation of the first snap-fit ​​part 11112 and the first connecting part 11111 of the first connecting unit 1111, so that the first connecting unit 1111 can be smoothly embedded into the connecting groove 222, and the first connecting unit 1111 and the second connecting unit 22 can be interference-fitted, thereby realizing the fastening assembly of the bracket 20 and the first housing 10 together.

[0054] Furthermore, the first connecting unit 1111 needs to be aligned with the connecting groove 222 before it can be inserted into the connecting groove 222. If the first connecting unit 1111 is not aligned with the connecting groove 222, it will be difficult for the first connecting unit 1111 to be inserted into the connecting groove 222. By providing the third guide slope 224 and the fourth guide slope 225, when the first connecting unit 1111 is not aligned with the connecting groove 222, the third guide slope 224 and the fourth guide slope 225 guide the first connecting unit 1111 to be aligned with the connecting groove 222, which makes it easier to assemble and connect the first connecting unit 1111 with the second connecting unit 22.

[0055] like Figure 1-5As shown, in the second direction y, the size of the first connecting part 11111 near the adsorption unit 23 gradually decreases in the third direction, and the size of the first connecting part 11111 away from the adsorption unit 23 gradually increases in the third direction, so as to form a first guide slope 11113. The first guide slope 11113 facilitates the first connecting unit 1111 to be embedded in the connecting groove 222.

[0056] Specifically, before the first connecting unit 1111 is inserted into the connecting groove 222, the two need to be aligned. If the first connecting unit 1111 is not aligned with the connecting groove 222, it will be difficult for the first connecting unit 1111 to be inserted into the connecting groove 222. By setting the first guide slope 11113, when the first connecting unit 1111 is not aligned with the connecting groove 222, the first guide slope 11113 guides the first connecting unit 1111 to align with the connecting groove 222, making it easier to connect the first connecting unit 1111 with the second connecting unit 22.

[0057] like Figure 1-5 As shown, in the first direction x, the size of the first snap-fit ​​portion 11112 gradually decreases in the third direction, and the size of the first snap-fit ​​portion 11112 gradually decreases in the second direction y to form a second guide slope 11114. The second guide slope 11114 facilitates the first snap-fit ​​portion 11112 to be embedded in the connecting groove 222.

[0058] Specifically, when the bracket 20 is assembled with the first housing 10, the first connecting unit 1111 needs to be embedded in the connecting groove 222. Since the first connecting unit 1111 is an interference fit with the second connecting unit 22, and the size of the first connecting unit 1111 is slightly larger than the size of the connecting groove 222, the first connecting unit 1111 needs to be deformed before being embedded in the connecting groove 222. Without the third guide slope 224, the first connecting unit 1111 would need to be squeezed to make its size smaller than the size of the connecting groove 222 before assembling the first connecting unit 1111 with the second connecting unit 22, making the assembly of the first connecting unit 1111 and the second connecting unit 22 difficult.

[0059] By setting the second guide slope 11114, the outer periphery of the second snap-fit ​​portion 226 is formed into a slope, so that the size of the outer periphery of the second snap-fit ​​portion 226 is smaller than the size of the center of the second snap-fit ​​portion 226. Thus, during the assembly of the first connecting unit 1111 and the second connecting unit 22, the second guide slope 11114 guides the outer edge of the connecting groove 222, causing the first connecting unit 1111 to deform, thereby allowing the first connecting unit 1111 to be smoothly embedded into the connecting groove 222, and making the first connecting unit 1111 and the second connecting unit 22 interference fit, thereby realizing the fastening assembly of the bracket 20 and the first housing 10 together.

[0060] In some embodiments, the first housing 10 has a first through hole 11115 at its center, the first through hole 11115 is disposed along a first direction x, and the first through hole 11115 passes through the first connecting portion 11111 and the second connecting portion 223. The above is merely illustrative of the technical solution of this utility model and not intended to limit it. Other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
