Further, to facilitate the assembly of the accessory 200 and the electronic device 100, one or more positioning posts 250 can be provided on the accessory 200, and one or more positioning holes 140 are provided on the device housing 110. The positioning posts 250 are inserted into the positioning holes 140, and through the cooperation of the positioning posts 250 and the positioning holes 140, the accessory 200 is positioned when the accessory 200 and the electronic device 100 are assembled, improving the assembly accuracy and efficiency.

[0045] Figure 6 Schematic structural diagram of the accessory and the electronic device in the locked state provided by the embodiment of the present application, Figure 7Schematic diagram of the structure of the accessory and the electronic device provided by the embodiment of the present application during the unlocking process; Figure 8 It is a schematic diagram of the structure of the accessory and the electronic device provided by the embodiment of the present application when fully unlocked. As Figures 6 to 8 shown, when the accessory 200 is assembled with the electronic device 100, the buckle 231 on the accessory 200 is snap-connected with the fixed buckle 120 on the electronic device 100 to fix the accessory 200 on the electronic device 100. Exemplarily, the buckle 231 is arranged on the bottom surface of the accessory 200 in the thickness direction, and the fixed buckle 120 is arranged on the top surface of the electronic device 100 in the thickness direction. When the accessory 200 is inserted into the electronic device 100, the buckle 231 located on the bottom surface of the accessory 200 is snap-connected with the fixed buckle 120 located on the top surface of the electronic device 100 to limit the accessory 200 in the first direction (width direction) of the accessory 200, so that the accessory 200 is fixed on the electronic device 100 and will not fall off the electronic device 100. When it is necessary to disassemble the accessory 200, push the push block 220 in the first direction. When the push block 220 moves in the first direction, it drives the bracket 230 to move in the second direction, so that the buckle 231 is disengaged from the fixed buckle 120, and the snap connection between the buckle 231 and the fixed buckle 120 is released. Then, push the accessory 200 in the first direction away from the electronic device 100, and the accessory 200 can be removed from the electronic device 100.

[0046] In this embodiment, the electronic device 100 is provided with a fixed buckle 120, and the accessory 200 is provided with a buckle 231. The accessory 200 and the electronic device 100 can be fixedly connected through the snap connection between the buckle 231 and the fixed buckle 120. When unlocking, pushing the push block 220 to move in the first direction drives the bracket 230 to move in the second direction, so that the buckle 231 and the fixed buckle 120 are disengaged, and the disassembly of the accessory 200 can be realized. The disassembly and assembly are convenient and fast, greatly improving the user experience. In addition, in this embodiment, the movement of the push block 220 in the first direction drives the bracket 230 to move in the second direction. The bracket 230 does not need to extend to the end of the accessory 200, which is convenient for the distribution of electronic components in the accessory 200 and can solve the problem of limited space.

[0047] In some embodiments, the conversion of the linear motion of the push block 220 in the first direction into the linear motion of the bracket 230 in the second direction can be achieved in various ways. For example, it can be achieved through a bevel surface cooperation, a cam structure, etc.

[0048] When it is achieved through the bevel surface cooperation method, as Figure 2As shown in the figure, the push block 220 is arranged at one end of the bracket 230. A first inclined surface 221 is provided on the side of the push block 220 close to the bracket 230, and a second inclined surface 232 is provided at one end of the bracket 230 close to the push block 220. The first inclined surface 221 cooperates with the second inclined surface 232 so that when the push block 220 moves in the first direction, it drives the bracket 230 to move in the second direction, so that the buckle 231 is disengaged from the fixed buckle 120. Through the cooperation of the two inclined surfaces, the movement of the push block 220 in the first direction is converted into the movement of the bracket 230 in the second direction. The structure is simpler, there are fewer components, and the cost is saved.

[0049] Optionally, the inclination angles of the first inclined surface 221 and the second inclined surface 232 are both 45 degrees. In this way, when the push block 220 moves a distance S in the first direction, the bracket 230 will move a distance S in the second direction, and the buckle 231 can be disengaged from the fixed buckle 120, and the buckling connection between the buckle 231 and the fixed buckle 120 is released. It should be noted that the inclination angles of the first inclined surface 221 and the second inclined surface 232 can also be other angles, such as 30 degrees, 60 degrees, etc., as long as it can be realized that when the push block 220 moves in the first direction, it drives the bracket 230 to move in the second direction and the buckle 231 is disengaged from the fixed buckle 120.

[0050] When realized by a cam structure, the push block 220 can be connected to the cam through a screw pair. When the push block 220 moves in the first direction, it drives the cam to rotate. The bracket 230 is located on one side of the cam. When the push block 220 is pushed in the first direction, it drives the cam to rotate. When the cam rotates, it drives the bracket 230 to move in the second direction, so that the buckle 231 is disengaged from the fixed buckle 120.

[0051] In some embodiments, such as Figure 2 and Figure 3As shown, the pushing block 220 and the bracket 230 are both arranged inside the fitting housing 210; on one side of the fitting housing 210 along the first direction, there is a pin hole 211, and the pin hole 211 is arranged corresponding to the pushing block 220. The pin hole 211 is arranged on the fitting housing 210, and the pushing block 220 is arranged inside the fitting housing 210. When unlocking is required, a stabbing needle or a pointed object can be inserted into the pin hole 211 and the pushing block 220 is pushed to move along the first direction. The pushing block 220 cooperates with the bracket 230 through an inclined surface, driving the bracket 230 to move along the second direction, so that the buckle 231 on the bracket 230 leaves the fixing buckle 120 on the electronic device 100, and the clamping connection between the buckle 231 and the fixing buckle 120 is released. In this embodiment, the pushing block 220 is arranged inside the fitting housing 210, and only the pin hole 211 is arranged on the fitting housing 210, which can not only realize the unlocking of the buckle 231 and the fixing buckle 120, but also has little influence on the appearance of the fitting 200. There is only one pin hole 211, which is relatively concealed. The specific size of the pin hole 211 in this embodiment is not limited, and the size of the pin hole 211 can be set according to actual needs, as long as a stabbing needle or a relatively pointed object can be inserted into the pin hole 211 and the pushing block 220 can be pushed to move.

[0052] Optionally, as Figure 2 shown, on the other side of the fitting housing 210 along the first direction, there is an elastic protrusion 212, and the elastic protrusion 212 protrudes from the outer surface of the fitting housing 210. The pin hole 211 is located on one side of the fitting housing 210 along the first direction, and the elastic protrusion 212 is located on the other side of the fitting housing 210 along the first direction. When the fitting 200 is assembled with the electronic device 100, the elastic protrusion 212 is located between the fitting 200 and the electronic device 100 and abuts against the electronic device 100, and the elastic protrusion 212 is deformed, pre-giving the fitting 200 a force in the disassembly direction. When the clamping connection between the buckle 231 and the fixing buckle 120 is released, the fitting 200 can quickly leave the electronic device 100 by a certain distance under the action of the elastic protrusion 212, so as to facilitate the removal of the fitting 200 from the electronic device 100, making the disassembly of the fitting 200 more convenient and labor-saving.

[0053] As Figure 2As shown, a notch 260 is provided on one side of the accessory housing 210 along the first direction. The notch 260 includes a first side wall and a second side wall, and the first side wall and the second side wall are oppositely arranged along the second direction. An elastic arm 270 is provided in the notch 260. The first end of the elastic arm 270 is fixedly connected to the first side wall, and there is a spacing between the second end of the elastic arm 270 and the second side wall. The elastic arm 270 forms a cantilever structure, and an elastic protrusion 212 is provided at the second end of the elastic arm 270. When the accessory 200 is assembled with the electronic device 100, the accessory housing 210 presses the elastic protrusion 212 of the elastic arm 270, and the second end of the elastic arm 270 can retract into the notch 260 of the accessory housing 210. When the buckle 231 is disengaged from the fixed buckle 120, the elastic arm 270 resets, causing the accessory 200 to automatically pop out in a direction away from the electronic device 100, facilitating the disassembly of the accessory 200. In this embodiment, the deformation amount of the elastic arm 270 is generally designed to be greater than 1 mm, that is, the pre-pressing movement stroke of the accessory 200 is greater than or equal to 1 mm, and the distance for the accessory 200 to automatically pop out is greater than or equal to 1 mm, facilitating the disassembly of the accessory 200. The elastic arm 270 can be made of plastic material, and the push block 220 and the bracket 230 can also be made of plastic material to reduce costs.

[0054] In some embodiments, as Figure 2 shown, the accessory 200 further includes an elastic member 280. One end of the elastic member 280 is fixedly connected to the accessory housing 210, and the other end of the elastic member 280 is fixedly connected to the bracket 230. The elastic member 280 is used to reset the bracket 230 and keep the buckle 231 and the fixed buckle 120 in a locked state.

[0055] When the push block 220 moves along the first direction to drive the bracket 230 to move along the second direction and unlock the buckle 231 from the fixed buckle 120, the elastic member 280 is in a stretched state and has a pulling force to return the bracket 230 to its initial position, or the elastic member 280 is in a compressed state and has a pushing force to return the bracket 230 to its initial position. After releasing the push block 220, the bracket 230 resets under the pulling force or pushing force of the elastic member 280. The bracket 230 resets and drives the push block 220 to reset, facilitating the next engagement of the buckle 231 and the fixed buckle 120. When the buckle 231 is engaged with the fixed buckle 120, under the pulling force or pushing force of the elastic member 280, the buckle 231 and the fixed buckle 120 are kept in an engaged state to lock the accessory 200 with the electronic device 100. The elastic member 280 can be a spring or a tension spring.

[0056] This application also provides an embodiment of an electronic device assembly, as Figures 1 to 8As shown in the figure, it includes an electronic device 100 and a fitting of the electronic device described in any of the above embodiments. When the fixing buckle 120 on the electronic device 100 is snapped with the buckle 231 on the fitting 200, the fitting 200 is fixed on the device housing 110. When disassembling, only need to push the push block 220 to disengage the buckle 231 from the fixing buckle 120. The disassembly and assembly are convenient, fast, time-saving and labor-saving.

[0057] An installation opening 150 is provided on the device housing 110, the fixing buckle 120 is arranged in the installation opening 150, and the fitting 200 is inserted into the installation opening 150 along the first direction. An expansion opening 130 is arranged on one side surface of the installation opening 150 along the first direction. When the fitting 200 is inserted into the installation opening 150, the interface 240 on the fitting 200 is electrically connected to the expansion opening 130 on the electronic device 100 to realize signal transmission. The fitting 200 is installed in the installation opening 150, which can prevent the fitting 200 from protruding from the electronic device 100, not only improving the aesthetics, but also avoiding affecting other electronic devices.

[0058] A first guiding surface 2311 is provided on one side of the buckle 231, and a second guiding surface 121 is provided on one side of the fixing buckle 120; the first guiding surface 2311 and the second guiding surface 121 cooperate so that when the fitting 200 is inserted into the installation opening 150, the fixing buckle 120 and the buckle 231 can be automatically snapped. Guiding surfaces are provided on both the buckle 231 and the fixing buckle 120. When assembling the fitting 200, the fitting 200 can be directly pushed along the first direction towards the electronic device 100, and automatic locking of the fitting 200 can be achieved when pushed to the end. The assembly is convenient, fast, time-saving and labor-saving.

[0059] In the above embodiments, the descriptions of each embodiment have their own emphases. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0060] It should be noted that the above embodiments can be freely combined according to needs. The above are only the preferred embodiments of the present application.
