Description

Technical Field

[0001] This utility model relates to the field of magnetic wireless charging gravity support technology, and in particular to a magnetic wireless charging gravity support. Background Technology

[0002] With the widespread use of electronic devices, mobile phones, wireless earphones, and rechargeable watches have become increasingly common. In particular, mobile phones have become a necessity in people's lives. These electronic devices have many functions and are used for a long time. Mobile phone stands are used to fix and support the placement of mobile phones. They are generally composed of a clip or suction cup and a base. Therefore, mobile phone stands play a supporting role and free up the hands.

[0003] The utility model patent with application number 201620912277.6 discloses a "stand-type wireless charging device" which includes a front shell and a positioning bracket. The wireless charging induction coil and the wireless charging control module are located inside the front shell. The rotation position of the positioning bracket can be adjusted as needed to "stand up" the wireless charging device so that the mobile phone can be charged vertically.

[0004] However, it has the following drawbacks: Since the position of the wireless charging stand is fixed, the position of the bottom support arm is also fixed. When different sized mobile phones are placed on the bottom support arm, the position of the mobile phone's wireless charging may be slightly higher or lower than the position of the wireless charging induction coil of the stand. This will cause the wireless charging induction coil to be misaligned, affecting the charging efficiency.

[0005] Therefore, in this utility model patent application, the applicant has carefully researched a magnetic wireless charging gravity bracket to solve the above problems. Utility Model Content

The second elastic reset member 52 can be disposed on at least one of the bottom support arm 30, the left clamping arm 41, and the right clamping arm 42.

[0063] When the mobile terminal is placed on the adsorption surface 101, the magnetic wireless charging base 10 moves downward relative to the housing under the gravity of the mobile terminal. When the bottom support arm 30 supports the lower end of the mobile terminal, the bottom support arm 30 moves downward relative to the housing under the gravity of the mobile terminal. At the same time, the downward movement of the bottom support arm 30 is linked to the left clamping arm 41 and the right clamping arm 42 to move towards each other to clamp and fix the mobile terminal.

[0064] In this embodiment, a first gear 43 and a second gear 44 are provided on the housing, and the first gear 43 and the second gear 44 are coaxially fixedly connected and move synchronously.

[0065] The left clamping arm 41 and the right clamping arm 42 both have a horizontal rack 401, and the bottom support arm 30 has a vertical rack 301. The vertical rack 301 and the horizontal rack 401 are respectively driven by the first gear 43 and the second gear 44 so that the bottom support arm 30, the left clamping arm 41 and the right clamping arm 42 are linked together.

[0066] The housing is provided with a guide block 23, and the left clamping arm 41 and / or the right clamping arm 42 are provided with guide grooves 402 that cooperate with the guide block 23.

[0067] When the left clamping arm 41 and / or the right clamping arm 42 move inward or outward relative to the housing, the guide groove 402 moves inward or outward relative to the guide block 23.

[0068] The housing has a first groove 24 extending vertically.

[0069] In this embodiment, the first gear 43, the second gear 44, the vertical rack 301, and the horizontal rack 401 are all located inside the housing 20.

The first sliding groove 24 and the second sliding groove 311 are arranged one after the other, and the length of the first sliding groove 24 is greater than the length of the second sliding groove 311.

[0073] The magnetic wireless charging base 10 is connected to a slider 11 that can be slidably installed in the first slide groove 24 and the second slide groove 311;

[0074] When the lower end of the mobile terminal contacts the bottom support arm 30, the slider 11 slides to the lower end of the second groove 311. Then, under the gravity of the mobile terminal, the bottom support arm 30 and the magnetic wireless charging base 10 move downward relative to the housing in sync.

[0075] Both the first elastic reset member 51 and the second elastic reset member 52 are reset springs; the two ends of the first elastic reset member 51 are respectively connected to the slider 11 and the bottom support arm 30, and the two ends of the second elastic reset member 52 are respectively connected to the housing and the bottom support arm 30.

[0076] When the mobile terminal is a large-sized phone, the first elastic reset component is stretched less; when the mobile terminal is a small-sized phone, the first elastic reset component is stretched more. In this way, by adjusting the stretching state of the first elastic reset component, it can adapt to phones of different sizes.

[0077] The bottom support arm 30 is provided with a first wire passage hole 35. The magnetic wireless charging base 10 includes a wireless charging base body and a charging coil located inside the wireless charging base body.

[0078] A control board 36 is provided inside the housing 20. The control board 36 is connected to a wire 37. The wire 37 passes through the first wire hole 35, the third wire hole 202, and the second wire hole 12 in sequence and is electrically connected to the charging coil.

[0079] A wire support block 38 for carrying the wire 37 is provided on the side of the bottom support arm 30 corresponding to the first wire hole 35.

[0080] The housing 20 has a cable tray 203 located near its edge sidewall. The cable support block 38 is located next to the outlet of the cable tray 203. The wire 37 is laid along the cable tray 203 and enters the first cable hole 35 through the cable support block 38.

[0081] The bottom support arm 30 is also provided with a mounting groove 312 extending vertically for mounting the first elastic reset member 51. The mounting groove 312 is located above the second slide groove 311 and the lower end of the mounting groove 312 is connected to the second slide groove 311. The width of the mounting groove 312 is smaller than the width of the second slide groove 311. The lower end of the first elastic reset member 51 extends into the second slide groove 311 and connects with the slider 11.

[0082] The mounting slot 312 is provided in two parallel positions with a left-right spacing. Correspondingly, the second sliding groove 311 and the first sliding groove 24 are also provided in two parallel positions with a left-right spacing. The first elastic reset member 51 is provided in two, each first elastic reset member 51 is adapted to a mounting slot 312, and each mounting slot 312 is connected to a corresponding second sliding groove 311.

[0083] In this embodiment, the bottom support arm 30 includes a mounting plate 302 and a support foot 34; the mounting plate 302 extends into the housing 20 through the clearance groove 201 at the lower end of the housing 20.

[0084] The mounting plate 302 is located behind the magnetic wireless charging base 10;

[0085] The mounting plate 302 includes a first vertical plate 31, an inclined plate 32, and a second vertical plate 33 connected sequentially from top to bottom;

[0086] Both the first sliding groove 24 and the mounting groove 312 are formed on the first vertical plate 31, and the vertical rack 301 is disposed on the first vertical plate 31. Preferably, the two ends of the first elastic reset member 51 are respectively connected to the slider 11 and the first vertical plate 31.

[0087] The inclined plate 32 is arranged at an angle from front to back and downwards. The inclined plate 32 provides clearance space.

[0088] The lower end of the second vertical plate 33 is connected to the support leg 34. In this embodiment, the two ends of the second elastic reset member 52 are respectively connected to the housing 20 and the second vertical plate 33.

[0089] The second vertical plate 33 has a mounting groove 313 extending vertically for mounting the second elastic reset member 52. The inner sidewall of the front shell 21 has a fixing block 211 protruding forward, and the fixing block 211 extends into the mounting groove 313.

[0090] The inner top wall of the mounting groove 312 is provided with a protruding post 314 for the upper end of the second elastic reset member 52 to be sleeved. The protruding post 314 extends into the upper end of the second elastic reset member 52, and the lower end of the second elastic reset member 52 is fixedly connected to the fixing block 211.

[0091] When the mobile terminal is attached to the adsorption surface 101, the magnetic wireless charging base 10 moves downward relative to the housing under the gravity of the mobile terminal. At this time, the first elastic reset member 51 is in a stretched state until the lower end of the mobile terminal contacts the bottom support arm 30. Then, the bottom support arm 30 moves downward relative to the housing under the gravity of the mobile terminal. At the same time, the downward movement of the bottom support arm 30 is linked to the left clamping arm 41 and the right clamping arm 42 to move inward to clamp the mobile terminal. At this time, the second elastic reset member 52 is in a compressed state.

[0092] After the mobile terminal is removed, the bottom support arm 30 moves upward relative to the housing under the elastic reset force of the second elastic reset member 52. At the same time, the upward movement of the bottom support arm 30 is linked to the outward movement of the left clamping arm 41 and the right clamping arm 42, and the left clamping arm 41 and the right clamping arm 42 move away from each other. The magnetic wireless charging base 10 automatically resets upward under the elastic reset force of the first elastic reset member 51.

[0093] The key design feature of this utility model is that the magnetic wireless charging base moves downward under the gravity of the mobile terminal and is reset by the action of the reset component, which can keep the position of the wireless charging receiver of mobile terminals of different sizes aligned with the magnetic wireless charging base, thereby improving charging efficiency.

[0094] Secondly, by setting two first elastic reset components, it is ensured that the magnetic wireless charging base will not shift during the displacement process;

[0095] Furthermore, the overall structural design is ingenious and reasonable, ensuring the stability and reliability of the product during use.

[0096] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
