  1, 2, and 3 are a three-dimensional view of the present invention, a diagram showing an internal structure, and an exploded view, respectively. The electric clamping device of the present invention includes a housing 1, a clamping unit 2, an electric drive unit 3, a control unit 4, a receiving member 5, a return spring 6, and a trigger unit 7. The clamping unit 2 has a first clamping arm 21 and a second clamping arm 22.

  As an operation of the present invention, when the user's mobile phone is to be clamped, the trigger unit 7 is triggered by pressing the receiving member 5 on the bottom side of the mobile phone, and the control unit 4 is moved to the electric drive unit 3. By controlling the above, the clamping unit 2 is separated by the electric drive unit 3, and the mobile phone is set before returning to the clamped state. When the user intends to remove the cellular phone, the cellular phone may be removed after the holding unit 2 is separated by following the same procedure of pushing the receiving member 5. In any procedure, since it is not necessary to touch other switches, the user can operate with one hand, so that the convenience of use can be improved.

  Next, the structure of each member will be described in detail.

  The housing 1 has a front cover 11 and a base housing 12, and the spaces formed by facing each other are for accommodating the respective members. The front cover 11 has an exposed placement surface 111, and the placement surface 111 is a place where a mobile phone is set. The base housing 12 is provided with a relative tank base for accommodating the respective members. For example, the first tank base 121 is for accommodating the main members of the electric drive unit 3. The guide tank set 122 is for smoothly sliding the first clamping arm 21 and the second clamping arm 22 and is an operation space for the electric drive unit 3 and the clamping unit 2. The slide holder 123 is for attaching the receiving member 5. The displacement hole 124 is for a member that works with the receiving member 5 to extend to the outside.

  The sandwiching unit 2 includes the first sandwiching arm 21 and the second sandwiching arm 22, and both the first sandwiching arm 21 and the second sandwiching arm 22 are substantially L-shaped, and are relatively left and right. By being disposed and partially attached in the housing 1, they can be smoothly approached or separated from each other, but cannot be separated from the housing 1. The portions where the first clamping arm 21 and the second clamping arm 22 extend to the outside of the housing 1 are positioned on both sides of the mounting surface 111, so that the cellular phone can be clamped.

  In this embodiment, when there is no external force, the first clamping arm 21 and the second clamping arm 22 need to maintain a state in which they automatically return to their original positions after the clamping force and separation. At least one spring in contact with these is provided inside 12. In this embodiment, two springs are provided, which are a first spring 23 and a second spring 24, respectively.

  The first clamping arm 21 has a first stop plate 211 extending toward the base housing 12, and after the assembly of the clamping unit 2 is completed, the first spring 23 is disposed in the base housing 12 and the first housing. It is located between the stop plate 211 and provides the urging force that returns from the first spring 23 to the original position by its own elastic force after the movement of the first clamping arm 21 and the first clamping arm 21.

  The second holding arm 22 has a second stop plate 221 extending toward the base housing 12, and after the assembly of the holding unit 2 is completed, the second spring 24 is connected to the inside of the base housing 12 and the second housing 24. It is located between the stop plate 221 and provides the urging force for returning from the second spring 24 to the original position by the clamping force of the second clamping arm 22 and its own elastic force after movement.

  The electric drive unit 3 contributes to the separation of the clamping unit 2. The electric drive unit 3 includes a motor 31, a gear 32, a first push block 33, and a second push block 34. The gear 32 is driven by the motor 31, the first push block 33 has a first rack 331, the first rack 331 meshes with the bottom position of the gear 32, and the second push block 34 The second rack 341 is meshed with the top position of the gear 32, and when the gear 32 is rotated, the first push block 33 and the second push block 34 are respectively in the upper and lower positions. Therefore, they can approach or separate from each other.

  As shown in FIG. 4, in the actual operation state, the first push block 33 comes into contact with the first stop plate 211 to push the first holding arm 21, and the second push block 34 The second clamping arm 22 is pushed by contacting the two-stop plate 221.

  In the present embodiment, the electric drive unit 3 is mainly for driving the separation of the clamping unit 2, and the return after the separation is due to the elastic force of the clamping unit 2 itself. The operation mode of the electric drive unit 3 is always operated several times in the clockwise direction and then stopped for a while, and then operates several times in the counterclockwise direction.

  When the electric drive unit 3 operates clockwise, the first push block 33 and the second push block 34 are interlocked and separated from each other. At this time, the first sandwiching arm 21 and the second sandwiching arm 22 are moved. While being separated (as shown in FIG. 4).

  On the other hand, when the counterclockwise operation is performed, the first push block 33 and the second push block 34 are interlocked to return to the original positions, and the first sandwiching arm 21 and the second sandwiching arm 22 are also moved while being interlocked. However, these movements are mainly due to the elastic force of the first spring 23 and the second spring 24. When the mobile phone is sandwiched, the first sandwiching arm 21 and the second sandwiching arm 22 do not move to the initial position, so even mobile phones having different widths can be clamped by the device of the present invention.

  The control unit 4 is a circuit board and controls the operation timing and mode of the motor 31 by being electrically connected to the electric drive unit 3 and the trigger unit 7. The control unit 4 is provided with a connector 41. The connector 41 is a USB connector, and external power is supplied to the inside of the apparatus via this connector.

  The receiving member 5 has a substantially L shape, and a part of the receiving member 5 is attached to the housing 1 and a portion extending to the outside protrudes from the mounting surface 111. The receiving member 5 is for supporting the bottom side of the mobile phone and can prevent the mobile phone from dropping. In the present invention, another main purpose of the receiving member 5 is to be used as an operation means of the electric clamping device in combination with the trigger unit 7.

  After the assembly of the receiving member 5 is completed, the receiving member 5 can be moved in the vertical direction for a short distance, so that the trigger unit 7 is triggered and returns to the original position after the external force disappears. can do. This is because the return spring 6 contributes. The return spring 6 is installed in the base housing 12, one end is fixed to the fixed column 126 of the base housing 12, and the other end is the receiving member. 5 is fixed.

  When there is no external force, the return spring 6 pulls the receiving member by its own elastic force and moves it to an initial position, that is, a position near the holding unit 2 side. Thereby, when the receiving member 5 is pushed down, the trigger unit 7 is triggered. In addition, by making the elastic force of the return spring 6 larger than the weight of the mobile phone, unnecessary touch to the set mobile phone can be prevented.

  The trigger unit 7 is a touch switch, and is provided with two metal elastic plates 71 and 72. When these metal elastic plates 71 and 72 are pressed and contacted, a signal is generated and transmitted to the control unit 4. Is done. In this embodiment, the trigger unit 7 is attached to the fixed base 125 of the base housing 12 and is electrically connected to the control unit 4. The position of the trigger unit 7 is adjacent to the receiving member 5.

  When the electric clamping device of the present invention is applied to a single-size mobile phone, the vertical position of the receiving member 5 is fixed, that is, the vertical position cannot be adjusted greatly, and only short-distance movement is possible. It becomes possible. Actually, a short distance movement of only 1 to 3 mm is possible.

  However, since the present invention is applied to mobile phones having different heights by expanding the operation range, in this embodiment, the vertical position of the receiving member 5 can be adjusted, and the structure of the member is the same as that of the operating member 81. A third spring 82 is provided. In this embodiment, the receiving member 5 is a substantially L-shaped member composed of at least one stop plate 51 and a connecting portion 52, and the connecting portion 52 includes a longitudinally penetrating guide tank 521 and two rows of unidirectional teeth 522. The unidirectional teeth 522 are located on both sides of the guide tank 521.

  The actuating member 81 has a cylindrical shape, has two convex teeth 811 at the relative position of the outer wall, and has a non-penetrated storage tank 812 at the center. The third spring 82 can be accommodated in the accommodating tank 812, the position of the displacement hole 124 of the base housing 12 corresponds to the operation member 81, and the longitudinal size L 1 of the displacement hole 124 is the operation member 81. By setting it to be larger than the outer diameter L2 (as shown in FIG. 6), the operating member 81 can move up and down in the displacement hole 124.

  Refer to FIGS. 5, 6, and 7 for the relative position of each member after the assembly of the receiving member 5 is completed. The operating member 81 passes through the guide tank 521, and a part thereof is extended to the outside through the displacement hole 124. The convex teeth 811 are engaged with the unidirectional teeth 522, and the third spring 82 is When the external force is not provided, the third spring 82 contributes to the engagement of the convex teeth 811 with the unidirectional teeth 522 so that the vertical length of the receiving member 5 is adjusted. Fix the directional position. One end of the return spring 6 is fixed to the fixed column 126, and the other end is hooked on the outer periphery of the operating member 81, thereby pulling the receiving member 5 and being positioned at a higher initial position. The actuating member 81 contacts the metal elastic plate 71 of the trigger unit 7.

  As shown in FIG. 5, when the user wants to adjust the longitudinal position of the receiving member 5 that extends to the outside of the housing 1, the user presses the operating member 81 toward the housing 1 (shown by the arrow in FIG. 5). As described above, the elastic force of the third spring 82 is canceled, and the convex tooth 811 is separated from the unidirectional tooth 522 so that the connecting portion 52 can be pushed downward (as shown in FIG. 4). ). Thereby, the vertical direction position in the said housing 1 of the said receiving member 5 can be changed significantly.

  As shown in FIG. 8, when the user actually applies an urging force to the receiving member 5 that is larger than the elastic force of the return spring 6 on the bottom side of the mobile phone, the convex teeth 811 are unidirectional. Since the operating member 81 is moved downward due to meshing with the teeth 522, the metal elastic plates 71 and 72 of the trigger unit 7 are in contact with each other to generate a signal, and the control unit 4 is connected to the electric drive unit 3. By controlling the operation, the clamping unit 2 is separated. In this embodiment, the receiving member 5 can be moved by a short distance of only 1 to 3 mm.

  Thereby, in the normal use state, in the electric clamping device of the present invention, the clamping unit 2 is in the clamping state. When a user tries to hold a mobile phone, the trigger unit 7 inside is triggered by pushing down the receiving member 5 on the bottom side of the mobile phone, and the control unit 4 is moved to the electric drive unit. 3 is controlled, the first clamping arm 21 and the second clamping arm 22 of the clamping unit 2 are sequentially separated, stopped, and clamped.

  The user sets the mobile phone in the stationary state, and the mobile phone is pinched when the user enters the pinched state. Since the pinched state is due to the pinching force from the internal first spring 23 and the second spring 24, the present invention can be applied to mobile phones having various widths. Since it is possible to remove the mobile phone by following the same procedure, the user can automatically hold or release the mobile phone by pressing it with one hand.

  Furthermore, the first separation state of the clamping unit 2 of the present invention may be realized by a radar microwave sensor. As shown in FIGS. 1, 2, and 3, the front cover 11 is further provided with two mounting holes 113, and the two radar microwave sensors 9 are installed in the mounting holes 113. The radar microwave sensor 9 is electrically connected to the control unit 4. In this embodiment, the radar microwave sensor 9 is installed on the control unit 4.

  As an operation or operation of the embodiment of the present invention, first, when the mobile phone approaches the electric clamping device, the radar microwave sensor 9 senses an external object approaching, so that a signal is generated and the control unit is operated. 4, the control unit 4 controls the electric drive unit 3 to separate the clamping unit 2. When attempting to remove the mobile phone, the series of operations is the same as in the above embodiment.

  The above description is only a preferred embodiment of the present invention, and does not limit the scope of the embodiment of the present invention, and equivalent changes and improvements based on the claims of the utility model registration of the present invention are not limited to the present invention. It should be included in the scope of the utility model registration request.
