[0005] 2. Due to the uncontrollability of the clamping force and the material factors of the component, the screen or paint surface of the component to be clamped will be scratched, or even the screen will be damaged, resulting in the damage of the component to be clamped. Summary of the Invention

[0015] Further, a boss is protrudingly provided in the middle of the first clamping portion, and the rear end surface of the boss is in movable abutment with the sensing device.
[0016] Further, the rear end surface of the first clamping portion is recessed to form a cavity with the base, and the rear end surface of the boss is located in the cavity.
[0017] Further, a butting plane is formed at the front end of the first clamping portion, the boss is arranged on the butting plane, and after the butting plane is recessed and deformed into the cavity, the rear end surface of the boss abuts against the sensing device.
[0018] Further, a sensor is provided at the rear side of the base, and a butting edge is protrudingly provided at the rear end of the second clamping portion. The butting edge is in movable abutment with the sensor and is used to provide a signal to the controller to stop the movement of the second clamping portion.
[0019] Further, a switch one for controlling the start of the driving unit is provided on the base, and through holes for mutual induction between the switch ones are provided on both the second clamping portion and the first clamping portion.
[0020] Further, a switch two for controlling the start of the driving unit is provided on the base. The bottom of the component to be clamped abuts against the switch two, presses the switch two, generates a signal change, and makes the driving unit work.
[0021] Further, a housing is provided outside the base, a U-shaped groove is provided on the housing, and the boss on the first clamping portion protrudes from the inner wall of the U-shaped groove.
[0022] Further, a clamping edge is protrudingly provided at the lower end of the first clamping portion. The clamping edge is in movable abutment with the inner wall of the housing, and the clamping position is smaller than the hooked end of the clamping convex edge.

[0027] 2. The setting of the boss on the first clamping part of the present invention can, during the clamping process, under the action of the boss, cause the middle part of the abutting plane to start to sink and deform into the cavity first, so as to abut against the sensing device. When the clamping force reaches the set value of the sensing device, the driving unit stops working. At this time, the upper and lower edges and the middle boss of the first clamping part support the component to be clamped, achieving the effect of three-point fixation at the upper, middle, and lower positions, ensuring the stability of clamping the component to be clamped and a constant clamping force, and avoiding the situation of excessive local clamping force and damage to the component to be clamped.
[0028] 3. The design of the cavity of the present invention can provide a deformation space for the abutting plane, and at the same time can reduce the external force required to trigger the deformation of the abutting plane, so that the clamping force is closer to the set value of the sensing device, achieving the purpose of facilitating the calculation and control of the clamping force and avoiding the problem of excessive clamping force and damage to the component to be clamped.

Detailed description of the specific implementation
[0040] The following further elaborates on the specific implementation of the present invention in conjunction with the attached drawings.
[0041] Embodiment 1:
[0042] As Figure 1 、 Figure 2 and Figure 5 shown, a clamping assembly includes a base 18, a drive unit 2 is arranged below the base 18. The base 18 includes a fixed base 1, a controller 21 is arranged on the fixed base 1, and a drive unit 2 is arranged on the lower end face of the fixed base 1. A second clamping part 3 is also movably arranged on the fixed base 1, and the drive unit 2 can drive the second clamping part 3 to move on the fixed base 1. An induction device is arranged at the front end of the fixed base 1, and a first clamping part 5 is arranged on the side of the induction device, and the two can be movably in contact with each other. A clamping position 6 for clamping the component to be clamped is formed between the second clamping part 3 and the first clamping part 5.
[0043] The base 18 can be a part of the housing, or the above-mentioned fixed base 1 or the sliding seat 12. The base 18 is a general term, and as long as it can carry the object to be clamped, it can be called a base.
[0044] The induction device includes a controller 21 and a pressure sensor 4 connected to the controller 21.
[0045] After the component to be clamped is placed in the clamping position 6, the controller 21 drives the driving unit 2. The driving unit 2 drives the second clamping part 3 to move, reducing the size of the clamping position 6. When the component to be clamped abuts against the first clamping part 5, the first clamping part 5 starts to deform under force and simultaneously triggers the pressure sensor 4. When the clamping force reaches the set value of the pressure sensor 4, a signal is sent to the controller 21, and the controller 21 then controls the driving unit 2 to stop working and maintain the existing clamping state, that is, the clamping of the component to be clamped is completed.
[0046] The set value can be selected according to the actual situation, and the value is not unique.
[0047] The design of the present invention improves the way of clamping the component to be clamped by movably arranging the second clamping part 3 on the fixed base 1 and using the driving unit 2 to drive the second clamping part 3 to move, so that the size of the clamping position 6 can be adjusted arbitrarily, enabling the clamping assembly to clamp components to be clamped with different thicknesses; at the same time, the pressure sensor 4 is used to control the size of the clamping force. When the clamping force is greater than the set value of the pressure sensor 4, the driving unit 2 will stop working, thus ensuring the controllability of the clamping force and solving the problem of damage to the component to be clamped caused by uncontrollable clamping force.
[0048] The driving unit 2 can adopt a motor.
[0049] Further setting, as Figures 3 - 6 shown, the entire first clamping part 5 can be made of rubber, with a relatively hard overall material, or other relatively hard elastic materials can also be used. The rear end face of the first clamping part 5 is recessed inward to form a groove 22. A cavity is formed between this groove 22 and the fixed base 1. As Figure 4 shown, the front end face of the first clamping part 5 is formed with an abutting plane 24, and the abutting plane 24 will be recessed and deformed into the cavity. The cavity provides the space required for the deformation of the abutting plane 24. At the same time, a boss 7 is provided in the middle of the abutting plane 24. Both end faces of the boss 7 protrude outside the first clamping part 5. The edge of the first clamping part 5 abuts against the outer shell 17 outside the fixed base 1, so the deformation amount at the edge is very small. If the boss 7 is not provided, then the entire abutting plane of the first clamping part 5 abuts against the component to be clamped, and the entire surface needs to deform to trigger the pressure sensor 4. In this way, a large clamping force is required to normally trigger the pressure sensor 4, which is likely to cause damage to the component to be clamped. Based on this, the boss 7 is provided.
[0050] As described in the clamping method above, after clamping the component to be clamped, as the driving unit 2 drives the second clamping part 3 to move, due to the design of the boss 7, the abutting plane 24 and the cavity, a relatively small external force will cause the deformation of the abutting plane 24 at the boss 7 part, thereby triggering the pressure sensor 4. After such a design, the additional force brought by the material deformation to the clamping of the component to be clamped can be reduced, which is convenient for calculating the clamping force and avoiding the problem of excessive clamping force.
[0051] In the clamping state, there are two clamping states: one is that the upper and lower edges and the middle boss 7 of the first clamping part 5 will support the component to be clamped. Since the upper and lower edges are directly abutted against the outer shell 17, the stability of the support points can be ensured, so as to achieve the effect of three-point fixation at the upper, middle and lower parts, ensure the stability of the clamping of the component to be clamped and the clamping force is constant, and avoid the situation of excessive local clamping force damaging the component to be clamped.
[0052] The other is to directly use the boss 7 to cooperate with the second clamping part 3 to clamp the component to be clamped.
[0053] Both clamping methods can realize the clamping of the component to be clamped, and can be selected according to the actual situation.
[0054] Further setting, as Figure 3 shown, in order to trigger the opening or closing of the clamping component of the component to be clamped, a switch one 10 for controlling the start of the driving unit 2 is provided on the fixed base 1. The switch one 10 can adopt a photoelectric switch. The switch one 10 includes a receiving end and a transmitting end, and the receiving end and the transmitting end are respectively located on both sides of the fixed base 1. Through holes 11 for mutual induction between the switch one 10 are provided on both the second clamping part 3 and the first clamping part 5. The light emitted by the transmitting end is received by the receiving end through the through hole 11, and the light passes through the clamping position 6.
[0055] In this embodiment, taking the photoelectric switch as an example, in actual use, the light emitted by the transmitting end is received by the receiving end through the through hole 11, and at this time it is in the standby state; when the component to be clamped, such as the component to be clamped is placed in the clamping position 6, the light is blocked, the signal received by the receiving end changes, the program works, the controller 21 controls the driving unit 2 to drive, and the clamping position 6 is reduced to clamp the component to be clamped. When the clamping force reaches the load of the pressure sensor 4, the controller 21 will control the driving unit 2 to stop working, and at this time the clamping action of the component to be clamped is completed.
[0056] When it is necessary to remove the component to be clamped, there are two situations: one is to directly pull out the component to be clamped. At this time, the light of switch 10 loses its shielding, and the controller 21 will directly control the driving unit 2 to work, moving the second clamping part 3 back to the initial position; the other is to set a button on the housing 17. When the button is pressed, the controller 21 will directly control the driving unit 2 to work, moving the second clamping part 3 back to the initial position.
[0057] In order for the driving unit 2 to stop working after the second clamping part 3 moves to the position, a sensor 9 is provided at the rear side of the fixed base 1. A bent abutting edge 8 protrudes from the rear end of the second clamping part 3, and the abutting edge 8 is in movable abutment with the sensor 9. The sensor 9 can be a pressure sensor, an inductive switch, a push-button switch or a microswitch.
[0058] When the abutting edge 8 abuts against the sensor 9 and sends a signal, it proves that the second clamping part 3 has moved to the initial position. After receiving the signal, the controller 21 stops the driving unit 2, that is, completes the action of the second clamping part 3 returning to the initial position, which facilitates the subsequent clamping action.
[0059] Further setting, as Figure 7 shown, a sliding seat 12 is provided on the fixed base 1. The edge of the sliding seat 12 is bent to form a C-shaped edge 15. A slider 16 is arranged inside the C-shaped edge 15, and the slider 16 is movably connected to the edge of the fixed base 1, and the sliding seat 12 can move on the fixed base 1. A driving unit 2 is further provided on the lower end surface of the fixed base 1. The driving unit 2 includes a motor and a lead screw 14. The lead screw 14 is connected to the driving unit 2. A connecting convex edge 13 is provided on the sliding seat 12, and a lead screw nut is arranged on the connecting convex edge 13. The driving unit 2 can drive the sliding seat 12 through the cooperation of the lead screw 14 and the lead screw nut.
[0060] As Figure 7 shown, in order to make the structure more compact, a movable notch 23 is opened on the fixed base 1. The connecting convex edge 13 is bent and located inside the movable notch 23, so that the connecting convex edge 13 can move inside the movable notch 23 to realize the movement of the sliding seat 12. This design can make full use of the space and will not cause the problem of the overall size of the clamping assembly being too large.
[0061] At the same time, the whole sliding seat 12 can be of an L-shaped design. The second clamping part 3 is connected to the vertical part of the sliding seat 12, and the second clamping part 3 is located above the sliding seat 12 as a whole. In this way, there will be a gap between the second clamping part 3 and the sliding seat 12. This gap can be used to install the bottom part of the U-shaped groove of the housing 17, so that the clamping position 6 is always inside the U-shaped groove, ensuring the normal use of the component to be clamped by the clamping assembly.
[0062] At the same time, when the fixed base 1 and the shell 17 are installed, the protrusion set on the inner wall of the shell 17 will cooperate with the fixed base 1 to form a snap-fit position, and the side of the first clamping part 5 is protruding with a snap-fit convex edge 20, and the end of the snap-fit convex edge 20 is hook-shaped.
[0063] When installing the first clamping part 5, it is only necessary to insert the clamping protrusion 20 into the clamping position so that the end is hooked in the clamping position, and the first clamping part 5 can be installed, which is also very convenient for subsequent maintenance and replacement.
[0064] In order to ensure the stability of the connection between the first clamping part 5 and the outer shell 17, an installation groove is opened on the side wall of the U-shaped groove of the outer shell 17. The middle part of the installation groove is hollow, and a clamping edge 19 is protruded from the lower end of the first clamping part 5. After the first clamping part 5 is installed on the outer shell 17, the edge of the first clamping part 5 is located in the installation groove, and the clamping edge 19 is movably abutted against the inner wall of the outer shell 17.
[0065] When clamping the component to be clamped, the edge of the first clamping portion 5 abuts against the inner wall of the mounting groove, and the mounting groove provides supporting force to ensure the stability of clamping. The design of the clamping edge 19 can be combined with the clamping convex edge 20 when the component to be clamped is not clamped to ensure that the first clamping portion 5 will not detach from the mounting groove, thereby ensuring the stability of the connection.
[0066] It is further configured that a shell 17 is provided outside the fixed base 1, a U-shaped groove is opened on the shell 17, the second clamping part 3 and the first clamping part 5 are respectively located on the two side walls of the U-shaped groove, a rubber pad is provided at the end of the second clamping part 3, and the rubber pad is mainly used for anti-slip and protection of the parts to be clamped; the side of the boss on the first clamping part 5 protrudes from the side wall of the U-shaped groove.
[0067] This design is mainly to protect the parts to be clamped. When clamping, the parts in contact with the rubber pad and the first clamping part 5 will not directly contact the outer shell 17, which can protect the parts to be clamped and will not scratch the surface paint, thereby ensuring the aesthetics of the parts to be clamped.
[0068] The above control instructions are all controlled by a controller, which can adopt some common single-chip microcomputers on the market to control the coordination of various parts through programs.
[0069] At the same time, in order to increase the practicality of the device, an external port can be installed in the U-shaped groove to connect other peripherals, so that the device can not only hold a mobile phone, but also install other products.
[0070] The clamping device also has an anti-pinching function, which is mainly implemented by setting a current detection device in the clamping device. The current detection device is mainly set on the controller and mainly includes multiple chip patches to collect the current of the motor. After amplification, it is transmitted to the controller, and the controller controls the drive unit to stop working.
[0071] The actual usage steps are as follows: When the driving unit drives the second clamping part 3 to move, the controller does not detect a valid signal transmitted by the pressure sensor 4, and the current of the motor exceeds the set value. The controller controls the driving unit to stop working and run in reverse to open the second clamping part 3, thus achieving the function of preventing pinching.
[0072] Embodiment 2:
[0073] It is basically the same as the structure of Embodiment 1, and the difference lies in that: as Figure 8 shown, a second switch 25 for controlling the start of the driving unit 2 is provided on the base 18. The second switch 25 can be a push-button switch or a trigger switch. When the component to be clamped abuts against the second switch 25, the component to be clamped may abut against it at the bottom, or on the side, or when placed, the hand abuts against the second switch 25. The triggering method is not unique. Pressing the second switch 25 generates a signal change to make the driving unit 2 work and realize the clamping operation.
[0074] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
