[0068] In this embodiment, the accessory body 12 includes a connecting portion 42 and an extension portion 44 connected to the connecting portion 42. The connecting portion 42 is U-shaped, and a slide groove 20 is formed on the inner side of the connecting portion 42. The connecting portion 42 is slidably mounted on the outer side of the frame bar 38 through the slide groove 20. The extension portion 44 extends from one side of the connecting portion 42 to above the mounting space 40 and corresponds to the position of the camera of the electronic product. The mounting opening 18 is provided through the extension portion 44. The U-shaped connecting portion 42 includes two side panels spaced apart and oppositely arranged, and a connecting plate connected between the two side panels. The slide groove 20 is located between the two side panels. The frame bar 38 can be inserted between the two side panels or withdrawn from between the two side panels. When the back panel 14 is mounted on the frame bar 38, the two side panels are located on opposite sides of the frame bar 38, and the connecting plate is located on the side of the frame bar 38 away from the mounting space 40. The extension portion 44 extends from one of the side panels into the mounting space 40.

[0069] Specifically, the connecting portion 42 and the extending portion 44 are integrally formed to ensure the overall strength of the back plate 14 .

[0070] In this embodiment, a guide protrusion 26 is provided on the inner side of the connecting portion 42, and a guide groove 24 is correspondingly provided on the outer side of the frame bar 38. When the connecting portion 42 is sleeved on the outer side of the frame bar 38, the guide protrusion 26 can be slidably inserted into the guide groove 24 to form a limiting effect in a direction perpendicular to the extension direction of the slide groove 20, thereby enhancing the stability of the connecting portion 42 on the frame bar 38.

[0071] Specifically, guide protrusions 26 are respectively provided on opposite sides of the connecting portion 42 , and the frame strip 38 has guide grooves 24 on opposite sides along the axial direction of the sleeve space 40 . Each guide protrusion 26 can be slidably inserted into a corresponding guide groove 24 .

[0072] In one embodiment, a locking structure is provided between the back panel 14 and the mounting portion 22. The locking structure has a locked state and an unlocked state. The back panel 14 can be slid relative to the mounting portion 22 to switch the locking structure between the locked and unlocked states. When the back panel 14 is mounted to the mounting portion 22, the locking structure is in the locked state, maintaining the back panel 14 relative to the accessory body 12 and enhancing the stability of the back panel 14 in the installed state. When the back panel 14 is removed from the mounting portion 22, the locking structure is in the unlocked state, releasing the locking effect and facilitating the sliding of the back panel 14 relative to the mounting portion 22.

[0073] It can be understood that the specific way in which the locking structure forms the locking effect is not limited. For example, the locking effect can be formed by snapping the back panel 14 and the mounting portion 22, or by the locking structure resisting the outer side of the back panel 14.

[0074] In the present application, the locking structure includes an elastic positioning member 46 provided on the mounting portion 22 and a corresponding positioning hole 48 provided on the back panel 14. In the locked state, the elastic positioning member 46 is inserted into the positioning hole 48. In the unlocked state, the elastic positioning member 46 is located outside the positioning hole 48. The elastic positioning member 46 is elastic and can be deformed. When the back plate 14 slides relative to the mounting portion 22, the back plate 14 will squeeze the elastic positioning member 46, and the elastic positioning member 46 will be deformed to prevent it from affecting the sliding of the back plate 14. When the back plate 14 slides until the positioning hole 48 moves to the elastic positioning member 46, the pressure of the back plate 14 on the elastic positioning member 46 disappears, and the elastic positioning member 46 returns to its initial state under the action of its own elastic force, so that the elastic positioning member 46 is inserted into the positioning hole 48, forming a locking effect, positioning the back plate 14 in this position to enhance the stability of the back plate 14 in this position, and continue to apply external force to the back plate 14 to make it slide relative to the accessory body 12. The back plate 14 squeezes the elastic positioning member 46 to deform it and withdraws from the positioning hole 48, releasing the locking effect.

[0075] It is understandable that the locking structure may also not have the positioning hole 48, and use the elastic positioning member 46 to resist the outside of the back panel 14. That is, when the back panel 14 is installed to the mounting portion 22, the elastic positioning member 46 and the back panel 14 are pressed against each other on one side of their sliding direction, which can also have a certain limiting effect on the back panel 14.

[0076] In other embodiments, the elastic positioning member 46 is provided on the back plate 14 and the positioning hole 48 is provided on the accessory body 12, which can also achieve the locking and unlocking effects.

[0077] The specific number of elastic positioning members 46 and positioning holes 48 is not limited and can be one or more. In the present application, the number of elastic positioning members 46 and positioning holes 48 is multiple and corresponds one to one. Multiple elastic positioning members 46 and multiple positioning holes 48 are arranged at intervals. In the locked state, each elastic positioning member 46 is inserted into a corresponding positioning hole 48, further enhancing the stability of the back plate 14 when it is installed on the accessory body 12.

[0078] like Figure 4 and Figure 5 As shown, in the embodiment where the accessory body 12 is a protective shell, the elastic positioning member 46 is provided on the side of the annular protrusion close to the back plate body 34 , and the positioning hole 48 is provided on the side of the back plate body 34 close to the annular protrusion.

[0079] Specifically, a mounting hole 56 is provided on a side of the annular protrusion near the back plate body 34. The elastic positioning member 46 includes an elastic member 58 positioned within the mounting hole 56 and a ball 60 connected to the elastic member 58. The ball 60 at least partially protrudes from the mounting hole 56, that is, the ball 60 protrudes from the outer surface of the annular protrusion. The positioning hole 48 is provided on a side of the back plate body 34 near the annular protrusion. As the back plate 14 slides relative to the annular protrusion, the back plate body 34 squeezes the ball 60, compressing and deforming the elastic member 58, causing the ball 60 to retract into the mounting hole 56. When the ball 60 moves to the positioning hole 48, the ball 60, under the action of the elastic member 58, extends from the mounting hole 56 and inserts into the positioning hole 48, thereby achieving a positioning effect.

[0080] In this embodiment, the number of elastic positioning members 46 and positioning holes 48 is two. The two elastic positioning members 46 and the two positioning holes 48 are arranged at intervals in a direction perpendicular to the sliding direction of the back plate 14. During the sliding process of the back plate 14, the two elastic positioning members 46 are inserted into the corresponding positioning holes 48 at the same time.

[0081] like Figure 8 and Figure 9 As shown, in the embodiment where the accessory body 12 is an expansion frame, the elastic positioning member 46 is provided on the side of the frame bar 38 away from the sleeve space 40 , and the positioning hole 48 is correspondingly provided on the connecting portion 42 of the back plate 14 .

[0082] Specifically, a mounting hole 56 is provided on the side of the frame strip 38 away from the sleeve space 40. The elastic positioning member 46 includes an elastic member 58 located in the mounting hole 56 and a ball 60 connected to the elastic member 58. The ball 60 at least partially protrudes from the outside of the mounting hole 56, that is, the ball 60 protrudes from the outer surface of the frame strip 38. The positioning hole 48 is correspondingly provided on the inner side of the connecting portion 42. During the sliding process of the back plate 14 relative to the frame strip 38, the connecting portion 42 will squeeze the ball 60 and compress and deform the elastic member 58, and the ball 60 will retract into the mounting hole 56. When the ball 60 moves to the positioning hole 48, the ball 60 extends from the mounting hole 56 under the action of the elastic member 58 and is inserted into the positioning hole 48, forming a positioning effect.

[0083] In this embodiment, the number of elastic positioning members 46 and positioning holes 48 is two. The two elastic positioning members 46 and the two positioning holes 48 are perpendicular to the length direction of the frame strip 38, that is, the sliding direction of the back panel 14. During the sliding process of the back panel 14, the two elastic positioning members 46 are successively inserted into the corresponding positioning holes 48.

[0084] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
