[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the invention to this.

[0034] like Figures 1 to 10 As shown in the figure, the wireless charger with linkage storage and clamping described in this embodiment includes a charging base 1; the bottom of the charging base 1 is provided with a support member 2 that can slide up and down, the support member 2 is used to provide support for the charging terminal; a first tension spring 22 is provided between the support member 2 and the charging base 1 to provide a reset function for the support member 2; the left and right side walls of the charging base 1 are symmetrically provided with receiving cavities 11; each of the two receiving cavities 11 is provided with a clamping unit 3;

[0035] Two clamping units 3 are mirror images of each other; the two clamping units 3 are movably connected to the support member 2 to realize the linkage between the clamping unit 3 and the support member 2; the clamping unit 3 has a storage state and a clamping state; when the support member 2 slides downward against the tension of the first tension spring 22, the clamping unit 3 changes from the storage state to the clamping state; when the support member 2 slides upward under the tension of the first tension spring 22, the clamping unit 3 changes from the clamping state to the storage state.

[0036] Specifically, when the charging terminal is placed on the support 2, the charging terminal causes the support 2 to slide downwards against the tension of the first tension spring 22. The support 2 drives the two clamping units 3 to simultaneously switch from a storage state to a clamping state until the two clamping units 3 clamp and fix the charging terminal from the left and right sides. Figure 5 and Figure 6 As shown; when the charging terminal is removed from the support member 2, the support member 2 slides upward and resets under the tension of the first tension spring 22. At this time, the support member 2 drives the two clamping units 3 to synchronously switch from the clamping state to the storage state until the clamping units 3 are housed in the storage cavity, as shown. Figures 1 to 3 As shown.

[0037] The embodiment links between the support 2 and the two clamping units 3, so that the clamping units 3 are automatically unfolded and clamped after the charging terminal is placed on the support 2, and are automatically stored and hidden after the charging terminal is removed. Only one hand operation is needed during use, the use operation is more convenient, the space occupied by the clamping units 3 when not in use is reduced, dust accumulation and collision damage are reduced, and the use experience is improved.

[0038] Specifically, as shown in Figures 1 to 7 、 Figure 9 and Figure 10 , the clamping unit 3 of the embodiment includes a driving member, a second tension spring 32, a clamping slider 33, a turnover block 34, and a first clamping block 35; the driving member is horizontally arranged in the receiving cavity 11, and the clamping slider 33 is horizontally and slidingly arranged in the receiving cavity 11; a first transmission member is rotationally arranged at the upper end of the clamping slider 33 and is in transmission connection with the driving member; the clamping slider 33 is also movably hinged to the support 2; the second tension spring 32 is connected between one side of the clamping slider 33 and the charging base 1; one side of the turnover block 34 is hinged to the other side of the clamping slider 33; a second transmission member is rotationally arranged at the upper end of the turnover block 34 and is in transmission connection with the first transmission member; an elastic energy storage member is connected between the second transmission member and the turnover block 34; one side of the first clamping block 35 is arranged at the other side of the turnover block 34;

[0039] In the storage state, as shown in Figure 3 , the clamping slider 33, the turnover block 34, and the first clamping block 35 are stored in the receiving cavity 11; in the clamping state, the clamping slider 33, the turnover block 34, and the first clamping block 35 are extended out of the receiving cavity 11, and the turnover block 34 drives the first clamping block 35 to overturn 90 degrees relative to the clamping slider 33, as shown in Figure 5 The wireless charger of the linkage storage and clamping of the embodiment, in some embodiments, as shown in Figure 7 、 Figure 9 and Figure 10 , the driving member is a rack 31, the first transmission member is a first gear 332, the second transmission member is a second gear 342, and the elastic energy storage member is a coil spring 36.

[0040] When the charging terminal is placed on the support 2, the support 2 drives the clamping slider 33 to slide outward, the clamping slider 33 drives the turnover block 34 and the first clamping block 35 to slide outward, at this time, the turnover block 34 is limited from turning over due to being located in the accommodation cavity 11, the rack 31 drives the first gear 332 to rotate, the first gear 332 drives the second gear 342 to rotate, the second gear 342 drives the coil spring 36 to store energy, the second tension spring 32 is stretched, and until the clamping slider 33 slides to the position, the turnover block 34 moves out of the accommodation cavity 11 and is not limited by the charging base 1, at this time, the second gear 342 cannot rotate due to being limited by the first gear 332, the coil spring 36 releases the stored energy and drives the turnover block 34 to drive the first clamping block 35 to turn over by 90 degrees, since the turning over angle of the turnover block 34 is only 90 degrees, that is, 1 / 4 turn of the coil spring 36, and since the number of energy storage turns of the coil spring 36 is greater than 1 / 4 turn, at this time, the stored energy of the coil spring 36 is not completely released, that is, the first clamping block 35 is still subjected to the force of the coil spring 36, so that the first clamping block 35 can always tightly adhere to the side wall of the charging terminal, thereby enhancing the clamping stability, at this time, the clamping unit 3 is in a clamping state, as shown in Figure 5 and Figure 6 .

[0041] When the charging terminal is removed from the support 2, the support 2 drives the clamping slider 33 to slide inward, at the same time, the second tension spring 32 pulls the clamping slider 33 to reset inward, the clamping slider 33 drives the turnover block 34 to move inward, so that the turnover block 34 drives the first clamping block 35 to reverse turn over, so that the coil spring 36 stores energy, at the same time, the rack 31 drives the first gear 332 to reverse rotate, the first gear 332 drives the second transmission to reverse rotate, thereby driving the coil spring 36 to release the stored energy, until the turnover block 34 reversely turns over by 90 degrees, with the reset of the support 2, the clamping slider 33 drives the turnover block 34 and the first clamping block 35 to retract into the accommodation cavity 11, the elastic potential energy of the coil spring 36 gradually decreases and returns to the initial point, at this time, the clamping unit 3 is in a storage state, as shown in Figures 1 to 3 .

[0042] As shown in Figure 3 , Figures 7 to 10 , the wireless charger of the linkage storage and clamping of the embodiment, in some embodiments, the accommodation cavity 11 is provided with an inclined table top 12, and the low end of the inclined table top 12 is close to the opening position of the accommodation cavity 11; the clamping slider 33 is vertically provided with a first sliding rod 333 which can slide up and down; the lower end of the first sliding rod 333 is movably abutted against the inclined table top 12; the lower end of the first sliding rod 333 is further provided with a connecting rod 334; one end of the connecting rod 334 is fixedly connected with the first sliding rod 333; the support 2 is connected with a second sliding rod 23 which can slide up and down in the storage cavity; the second sliding rod 23 is perpendicular to the first sliding rod 333; the second sliding rod 23 is slidably hinged to the other end of the connecting rod 334.

[0043] Specifically, when the charging terminal is placed on the support 2, the support 2 slides downward, the first tension spring 22 is stretched, the support 2 drives the second slide rod 23 to slide downward, the second slide rod 23 drives the first slide rod 333 to slide downward, and since the lower end of the first slide rod 333 is in movable abutment with the inclined table top 12, as shown in Figure 3 the first slide rod 333 simultaneously slides outward horizontally, thereby driving the clamping slider 33 to drive the turnover block 34 and the first clamping block 35 to move outward out of the accommodation cavity 11, and the second tension spring 32 is stretched; after the downward pressing on the support 2 is released, the first slide rod 333 moves upward, and the second tension spring 32 synchronously drives the clamping slider 33 to slide inward, thereby realizing the accommodation of the turnover block 34 and the first clamping block 35. In this way, through the cooperation between the first slide rod 333 and the second slide rod 23, linkage between the support 2 and the clamping unit 3 is realized, thereby realizing automatic clamping and accommodation operation, and clamping operation is convenient.

[0044] As shown in Figure 3 and Figure 7 the wireless charger of the linkage accommodation and clamping of the present embodiment, in some embodiments, the support 2 includes a support table 211 and two extension columns 212 arranged at intervals on the support table 211; the upper ends of the two extension columns 212 are movably penetrated into the corresponding accommodation cavities 11 and are fixedly connected with the second slide rod 23; the first tension spring 22 is sleeved on the outer wall of the extension column 212, and the two ends of the first tension spring 22 are connected with the extension column 212 and the charging base 1 respectively. In the present embodiment, two extension columns 212 are arranged to facilitate the connection of the support table 211 with the second slide rod 23 and the installation of the first tension spring 22, so that the movement of the support 2 is more stable, and the support 2 can provide more reliable support for the charging terminal.

[0045] As shown in Figure 10 the wireless charger of the linkage accommodation and clamping of the present embodiment, in some embodiments, the turnover block 34 is provided with an inclined groove 341 on the other side, and the first clamping block 35 is provided with a boss 351 on one side; the boss 351 is slidingly connected in the inclined groove 341; the inclined groove 341 is provided with a spring 37; and the two ends of the spring 37 are connected with the boss 351 and the turnover block 34 respectively. In the present embodiment, the inclined groove 341, the boss 351 and the spring 37 are arranged in cooperation, so as to adapt to the clamping and fixing of charging terminals of different widths.

[0046] When the first clamping block 35 is pressed against the charging terminal edge, that is, the charging terminal presses the first clamping block 35, the first clamping block 35 slides relative to the turnover block 34, the boss 351 slides in the inclined groove 341, and the spring 37 is compressed. Since the first clamping block 35 is matched with the inclined groove 341 through the boss 351, during the sliding of the first clamping block 35 relative to the turnover block 34, the first clamping block 35 has both horizontal displacement and vertical displacement, thereby achieving automatic adjustment to adapt to the width of the placed charging terminal and realizing stable and reliable clamping. Since the length of the existing charging terminal is proportional to the width, when the width of the charging terminal increases, the length increases by the same proportion, so that the upward movement of the first clamping block 35 can make the clamping more stable.

[0047] As shown in Figures 1 to 3 , Figure 7 , Figure 9 and Figure 10 , the linkage storage and clamping wireless charger of the present embodiment, in some embodiments, the clamping unit 3 further comprises a second clamping block 38 slidingly arranged on the other side of the first clamping block 35; the second clamping block 38 and the first clamping block 35 are connected by a third tension spring 39. The present embodiment can adapt to charging terminals of different thicknesses by providing a second clamping block 38 and a third tension spring 39 on the first clamping block 35, and the structure is more applicable. At the same time, the second clamping block 38 can clamp and fix the charging terminal from the thickness direction of the charging terminal, and the clamping and fixing effect is further improved. When the charging terminal is removed from the support 2, the charging terminal can be directly pulled out upward.

[0048] As shown in Figure 10 , the linkage storage and clamping wireless charger of the present embodiment, in some embodiments, the second clamping block 38 is spaced apart and has two slide columns 381; the two slide columns 381 slide through the first clamping block 35; each slide column 381 and the first clamping block 35 are connected by a third tension spring 39.
