[0031] like Figures 1-3 As shown, one embodiment of this utility model is:

[0032] The magnetic back clip includes a back plate 1 and a back clip assembly 2. The front side of the back plate 1 is used to connect with a mobile phone, and the rear side of the back plate 1 is respectively provided with a first magnetic component 11, a locking groove 12 and a positioning post 13. The back clip assembly 2 includes: a housing 21, a second magnetic component 22, a control base 23, two locking tongue assemblies 24 and two control components 25.

[0033] The front side of the housing 21 is used to dock with the back plate 1, and the rear side is used to connect to the external bracket;

[0034] The second magnetic component 22 is disposed inside the housing 21 and matches the first magnetic component 11 for magnetic connection with the back plate 1.

[0035] The control seat 23 is elastically and slidably disposed in the housing 21 in the front-back direction, and its front end abuts against the positioning post 13;

[0036] Two locking tongue assemblies 24 are slidably disposed in the housings 21 on both sides of the control seat 23 along the second direction, and respectively engage with the locking groove 12 and the control seat 23;

[0037] Two control components 25 correspond one-to-one with two locking tongue components 24 and are slidably disposed on both sides of the housing 21. The first end of each control component 25 extends out of the housing 21, and its second end abuts against the locking tongue component 24.

[0038] In use, connect the front side of the back panel 1 to the mobile phone. The front side of the back panel 1 can be directly pasted onto the mobile phone, pasted onto the mobile phone case, or integrally formed with the mobile phone case. Press the two control components 25 simultaneously towards the inside of the housing 21, so that the control seat 23 locks the two locking tongue components 24 simultaneously. Move the front side of the housing 21 close to the rear side of the back panel 1. The second magnetic component 22 and the first magnetic component 11 attract each other, so that the back panel 1 and the housing 21 are aligned. At this time, the positioning post 13 abuts against the control seat 23, and the positioning post 13 pushes... When the control base 23 moves backward, the two locking tongue assemblies 24 are unlocked from the control base 23, and at the same time, the two locking tongue assemblies 24 are locked to the locking groove 12. At this time, the back clip assembly 2 can be connected to the external bracket. When the back clip assembly 2 and the back plate 1 are separated, the two control components 25 are pressed at the same time, causing the two locking tongue assemblies 24 to move inward respectively, and the two locking tongue assemblies 24 are separated from the locking groove 12. At the same time, the control base 23 locks the two locking tongue assemblies 24 simultaneously. Then the first magnetic suction assembly 11 and the second magnetic suction assembly 22 can be separated.

[0039] This application uses the first magnetic suction component 11 and the second magnetic suction component 22 to quickly connect the back plate 1 and the back clip component 2. The positioning post 13 on the back plate 1 controls the positioning seat, thereby locking the two locking tongue components 24 and the locking groove 12, making the connection between the back plate 1 and the back clip component 2 more stable and preventing them from shifting positions. The two locking tongue components 24 are controlled by two control components 25 respectively, and the two locking tongue components 24 are locked by the control seat 23, making the separation of the back plate 1 and the back clip more convenient and quick. At the same time, the first magnetic suction component 11 and the second magnetic suction component 22 can prevent the mobile phone from falling.

[0040] In one embodiment, such as Figure 4 As shown, the control seat 23 includes a sliding part 231, a locking part 232, a first control part 233 and a second control part 234. The sliding part 231 is slidably connected to the housing 21, the locking part 232 is engaged with the locking tongue assembly 24, the first control part 233 extends out of the housing 21 and abuts against the positioning post 13, and the second control part 234 is elastically connected to the rear side of the housing 21.

[0041] Specifically, the sliding part 231 includes two sliding arms disposed on the upper and lower sides of the control base 23. The two sliding arms are slidably connected to the housing 21 to maintain the stability of the control base 23 in the front-back direction. The locking part 232 includes two locking arms disposed on the left and right sides of the control base 23. The two locking arms control the two locking tongue assemblies 24 respectively. The first control part 233 is disposed on the front side of the control base 23 and extends out of the housing 21 to abut against the positioning post 13. The second control part 234 is elastically connected to the rear side of the housing 21.

[0042] In one embodiment, such as Figure 5As shown, the latch assembly 24 includes a movable seat 241, a latch 242, and a first spring 243. The movable seat 241 is slidably disposed in the housing 21 in the left and right direction. A control groove 244 is provided on its rear side near the control seat 23. The control groove 244 engages with the locking part 232. The latch 242 is disposed on the front side of the movable seat 241 and engages with the locking groove 12. The first spring 243 connects the movable seat 241 and the housing 21 and is used to keep the latch 242 moving towards the locking groove 12.

[0043] Understandably, when the movable seat 241 moves toward the control seat 23, the first spring 243 is stretched, and the locking part 232 of the control seat 23 enters the control groove 244, locking the movable seat 241. When the positioning pin 13 and the first control part 233 abut, the positioning pin 13 pushes the control seat 23 to move backward, the locking part 232 and the control groove 244 disengage, the first spring 243 resets, causing the movable seat 241 to slide outward, thereby locking the latch 242 and the locking groove 12.

[0044] In one embodiment, such as Figure 6 As shown, the control component 25 includes a button 251 and a second spring 252. The button 251 is slidably disposed inside the housing 21, with its first end extending out of the housing 21 and its second end respectively provided with an abutment part 253 and a spring seat 254. The abutment part 253 abuts against the movable seat 241 and is used to control the latch assembly 24. The second spring 252 is sleeved on the spring seat 254 and is used to keep the button 251 moving out of the housing 21.

[0045] In this embodiment, the second spring 252 is connected to the two control components 25 respectively, so that the two control components 25 are kept far apart from each other.

[0046] In one embodiment, such as Figure 3 As shown, a return spring 231 is provided on the rear side of the control seat 23. The return spring 231 keeps the control seat 23 moving forward. When the locking tongue assembly 24 moves inward, the locking tongue assembly 24 is automatically locked.

[0048] It is understood that the groove 14 can be circular, quadrilateral, or polygonal. The locking groove 12 can be a slot that surrounds the inner wall of the groove 14, or it can be two slots that are opposite to each other on both sides of the inner wall of the groove 14. The two slots are respectively engaged with the two locking tongues 242. In this embodiment, the groove 14 is quadrilateral. In order to facilitate switching between horizontal and vertical orientation of the mobile phone, four slots are respectively opened on the four inner walls of the groove 14.

[0049] In one embodiment, such as Figure 2 As shown, a boss 211 is provided on the front side of the housing 21, and the boss 211 matches the groove 14.

[0050] It is understandable that when the groove 14 is circular, the boss 211 is also circular, and when the groove 14 is polygonal, the boss 211 is also polygonal. In this embodiment, the groove 14 is quadrilateral, and the boss 211 is also quadrilateral. When the two are joined, the boss 211 enters the groove 14.

[0051] In one embodiment, such as Figure 1 As shown, the first magnetic attraction component 11 includes a first magnet, and multiple first magnets are respectively disposed at the bottom of the groove 14. In this embodiment, there are four first magnets, which are respectively disposed at the four corners of the bottom of the groove 14.

[0052] In one embodiment, such as Figure 3 As shown, the second magnetic attraction component 22 includes a plurality of second magnets, each of which corresponds to and is magnetically connected to a plurality of first magnets. In this embodiment, there are four first magnets and four second magnets.

[0053] In one embodiment, such as Figure 1 As shown, a connecting seat 212 is provided on the rear side of the housing 21, which is used to connect an external bracket.

[0054] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
