[0035] See also Figure 1 The utility model provides a suction cup clamp, comprising a first rod body 11, a second rod body 12, a handle 60 and a suction cup 13. The number of the second rod bodies 12 is at least two. Preferably, the number of the second rod bodies 12 is two, and the upper ends of the two second rod bodies 12 are respectively connected to the two opposite ends of the first rod body 11, and the lower ends of the two second rod bodies 12 are respectively connected to the two suction cups 13. Optionally, the second rod body 12 is integrally formed with the first rod body 11, or is fixedly connected to the first rod body 11 by means of threaded connection or the like. The suction cups 13 at the lower ends of at least two second rod bodies 12 include a first suction cup for adsorbing workpieces such as a controller, and a second suction cup for adsorbing on a vehicle body. Through the cooperation of the first suction cup and the second suction cup, the controller can be pre-positioned to the vehicle body.

[0036] Furthermore, the handle 60 is fixedly connected to the first rod 11, and the suction cup 13 is connected to the end of the second rod 12 away from the first rod 11. Specifically, the handle 60 includes a gripping portion 61 disposed opposite the first rod 11, and a connecting rod 62 connecting the gripping portion 61 and the first rod 11. The gripping portion 61 and the connecting rod 62 can be fixedly connected or integrally formed by bolting, welding, or the like. The connecting rod 62 and the first rod 11 can be fixedly connected or integrally formed by bolting, welding, or the like. In addition, the length of the gripping portion 61 is less than the length of the first rod 11, and in this embodiment is approximately 1 / 3 of the length of the first rod 11. This leaves the sides of the first rod 11 near the gripping portion 61 at both ends free, reducing the space occupied by the suction cup fixture and enabling the suction cup fixture to adapt to smaller workpiece installation spaces. The suction cup 13 can be fixedly connected to the end of the second rod 12 by threading, snapping, interference fit, adhesive bonding, or the like. Optionally, the suction cup 13 protrudes axially outward at one end close to the second rod body 12 to form a hollow cylindrical connecting section, and the connecting section and the second rod body 12 are sleeved with each other. In one example, the connecting section is sleeved on the end of the second rod body 12 and has an interference fit with the second rod body 12. In another example, the connecting section is provided with an external thread, and the second rod body 12 is provided with an internal thread that cooperates with the connecting section, so that the suction cup 13 is fixed to the end of the second rod body 12 by a threaded connection.

[0037] Preferably, one of the two suction cups 13 includes an adhesive portion 131, and the other includes a magnetic portion (not shown). In one example, the adhesive portion 131 is attached to the surface of the suction cup 13 that contacts the controller, and the controller is picked up by viscosity. The magnetic portion is fixedly connected to the suction cup 13 and adsorbed to the vehicle body by magnetic attraction. In one example, the adhesive portion 131 can be made of a material that is both flexible and sticky, such as silicone, rubber, or polyurethane, so that it is not easy to leave residue or damage the surface of the controller when removed. In another example, the adhesive portion 131 can be made of a low-residue, easy-to-peel double-sided tape to ensure stable adsorption while facilitating non-destructive removal, thereby avoiding damage to the surface of the controller.

[0038] The suction cup clamp of the present invention further includes a control button 63 and a wiring harness 64. The control button 63 is at least partially embedded in the gripping portion 61 and is electrically connected to the magnetic portion via the wiring harness 64. Optionally, the magnetic portion includes a coil and a magnetic core disposed within the coil. The control button 63 is electrically connected to the coil via the wiring harness 64 to control the power on and off of the magnetic portion, thereby switching the suction cup 13 between adsorption and release from the vehicle body.

[0039] See also Figure 2 and Figure 3In some embodiments, at least one of the first rod 11 and the two second rods 12 includes a telescopic portion 20. The telescopic portion 20 allows the length of the second rod 12 to be adjusted to accommodate different workpieces, or the length of the first rod 11 to be adjusted to accommodate different workpiece installation locations on the vehicle body. Specifically, the telescopic portion 20 includes an outer sleeve 21 and an inner sleeve 22 that are interconnected. The outer sleeve 21 and the inner sleeve 22 are each provided with a plurality of limiting holes 211 arranged along their axial directions. A limiting member 23 is provided within the inner sleeve 22. The limiting member 23 at least partially passes through the corresponding limiting hole 211 to limit the relative position of the outer sleeve 21 and the inner sleeve 22.

[0040] Specifically, the limiting member 23 includes a clamping portion 23a that is at least partially clamped in the limiting hole 211, a first mounting plate 231 fixedly connected to the side of the inner sleeve 22 away from the limiting hole 211, a second mounting plate 232 fixedly connected to the clamping portion 23a, and a connecting plate 233 connecting the first mounting plate 231 and the second mounting plate 232. Figure 2 In the embodiment shown, the connecting plate 233 is arc-shaped. Figure 3 In the illustrated embodiment, the connecting plate 233 is V-shaped and made of an elastic material such as metal. The clamping portion 23a can apply force to the connecting plate 233 via the second mounting plate 232. The arc-shaped or V-shaped structure allows the connecting plate 233 to bend easily, accumulating elastic potential energy and providing a driving force for the clamping portion 23a to spring outward. By pressing the clamping portion 23a into the retaining hole 211 of the inner sleeve 22, the length of the inner sleeve 22 extending relative to the outer sleeve 21 can be adjusted. When the inner sleeve 22 slides relative to the outer sleeve 21 until the clamping portion 23a aligns with a retaining hole 211 on the outer sleeve 21, the elastic force of the connecting plate 233 pushes the clamping portion 23a into the retaining hole 211 of the outer sleeve 21, fixing the relative position between the inner sleeve 22 and the outer sleeve 21 and maintaining a relatively constant length of the inner sleeve 22 extending relative to the outer sleeve 21.

[0041] Preferably, both the outer sleeve 21 and the inner sleeve 22 are hollow prisms, for example, their cross-sections can be square or polygonal, thereby preventing relative rotation between the outer sleeve 21 and the inner sleeve 22, thereby facilitating the engagement of the clamping portion 23a in the limiting hole 211. Optionally, the outer sleeve 21 and the inner sleeve 22 are respectively provided with a second limiting portion and a first limiting portion (not shown) along the axial direction of the outer sleeve 21. Specifically, the inner sleeve 22 is recessed along its radial direction to form the first limiting portion, and the outer sleeve 21 is recessed along its radial direction to form a second limiting portion that cooperates with the first limiting portion. Optionally, the cross-sections of the first limiting portion and the second limiting portion are both roughly U-shaped. The second limiting portion cooperates with the first limiting portion to limit the circumferential position of the outer sleeve 21 relative to the inner sleeve 22, preventing rotation between the outer sleeve 21 and the inner sleeve 22, and ensuring the circumferential position of the clamping portion 23a and the limiting hole 211. Moreover, when the axial positions of the outer sleeve 21 and the inner sleeve 22 reach the limit positions, the opposite ends of the first limiting portion and the second limiting portion can abut against each other to prevent the inner sleeve 22 from falling out of the outer sleeve 21 .

[0042] See also Figure 4 In some embodiments, an angle adjustment member 30 for adjusting the relative angle between the two second rods 12 is further provided between the first rod 11 and the second rod 12. The angle adjustment member 30 is generally T-shaped or L-shaped, and includes a steering portion 40 and a connecting portion 50. Preferably, the steering portion 40 is perpendicular to the connecting portion 50. The steering portion 40 is connected to the first rod 11, and the connecting portion 50 is connected to the second rod 12. The steering portion 40 can be used to rotate the second rod 12 along the first direction around the axis of the first rod 11, thereby adjusting the relative angle between the two second rods 12. Optionally, the steering portion 40 and the connecting portion 50 are integrally formed, or the steering portion 40 is fixedly connected to the connecting portion 50 by means of threaded connection, adhesive bonding, etc.

[0043] See also Figures 5 to 7In some embodiments, the steering portion 40 includes a first steering ring 41 and a second steering ring 42. One of the first steering ring 41 and the second steering ring 42 is integrally connected to one of the outer sleeve 21 and the inner sleeve 22 of the telescopic portion 20, and the other of the first steering ring 41 and the second steering ring 42 is integrally connected to the connecting portion 50. The inner surface of the first steering ring 41 is circumferentially distributed with recessed adjustment grooves 411. The outer surface of the second steering ring 42 is circumferentially distributed with radially protruding adjustment teeth 412. The diameter of the circle on which the tips of the adjustment teeth 412 lie is slightly larger than the inner diameter of the first steering knuckle 41. This allows the first steering ring 41 to rotate relative to the second steering ring 42, driving the second rod 12 to rotate along the axis of the first rod 11, changing the relative angle between the two second rods 12 and further accommodating different installation positions of the workpiece on the vehicle body. Optionally, the inner surface of the first steering ring 41 is radially recessed to form a limiting groove, and the adjusting tooth 412 is at least partially embedded in the limiting groove to limit the relative position of the first steering ring 41 and the second steering ring 42 along the axial direction of the steering part 40, thereby improving the connection stability.

[0044] See also Figure 6 The two sidewalls of the adjustment groove 411 form arc-shaped guide surfaces 411a and planar stop surfaces 411b. When the second steering ring 42 rotates in the first direction, the adjustment teeth 412 can slide along the guide surfaces 411a, changing the relative angle between the two second rods 12. If the second steering ring 42 rotates in the opposite direction, the adjustment teeth 412 will abut against the stop surfaces 411b, preventing forward movement. This allows the second steering ring 42 to rotate only in one direction relative to the first steering ring 41, thereby limiting the relative angle between the two second rods 12. In one example, the adjustment teeth 412 include two substantially perpendicular tooth surfaces 412a, one of which is designed to mate with the stop surface 411b in the adjustment groove 411, ensuring that the steering portion 40 is locked in the predetermined position and improving stability. In another example, both sidewalls of the adjustment groove 411 can be arc-shaped. This allows for bidirectional rotation between the second steering ring 42 and the first steering ring 41, further facilitating the use of the suction cup clamp.

[0045] See also Figure 4In one example, the suction cup clamp of the present invention further includes a spring 24, which is disposed between the portion of the telescopic portion 20 without the limiting hole 211 and the angle adjustment member 30, facilitating length adjustment of the telescopic portion 20. In one example, the inner sleeve 22 of the telescopic portion 20 is integrally connected to the second steering ring 42 of the angle adjustment member 30, the outer sleeve 21 of the telescopic portion 20 is integrally connected to the portion of the first rod 11 near the handle 60, and the first steering ring 41 of the angle adjustment member 30 is integrally connected to the connecting portion 50. The spring 24 is sandwiched between the outer sleeve 21 of the telescopic portion 20 and the first steering ring 41 of the angle adjustment member 30. When the length of the telescopic portion 20 is shortened, the spring 24 is compressed, accumulating elastic potential energy, providing elastic thrust for the extension of the telescopic portion 20, making the extension operation of the telescopic portion 20 more labor-saving. When the length of the telescopic portion 20 exceeds a certain length, the spring 24 is stretched, accumulating elastic potential energy, providing elastic tension for shortening the telescopic portion 20, making shortening the telescopic portion 20 more labor-efficient. The above-described embodiment describes the spring 24 being located on the first rod 11. It is understood that the spring 24 can also be located on the second rod 12. When the spring 24 is located on the second rod 12, the specific conditions are similar to those when it is located on the first rod 11. The difference is that the component connected to the lower end of the spring 24 is replaced by the angle adjustment member 30 with the connecting section of the suction cup 13. The specific connection method is not repeated here.

[0046] When the suction cup clamp of the present invention is in use, the suction cup 13 with the adhesive portion 131 picks up the workpiece. When the workpiece is moved to the pre-positioned position of the vehicle body, the control button 63 is pressed to control the magnetic attraction portion to be energized to generate a magnetic attraction force. The magnetic attraction force is used to make the suction cup 13 with the magnetic attraction portion adsorbed to the vehicle body, and the workpiece is pre-positioned to the vehicle body; then the workpiece is fixed to the vehicle body by fasteners such as bolts and nuts. After the installation is completed, the control button 63 is pressed again to control the magnetic attraction portion to be de-energized. At this time, the suction cup clamp of the present invention can be removed from the vehicle body and the surface of the workpiece. It is easy to use and can improve work efficiency. When there is a front-to-back offset between the pre-positioning position of the magnetic part and the pre-positioning position of the workpiece, the relative angle between the two suction cups 13 can be adjusted by the angle adjustment part 30; when the distance between the pre-positioning position of the magnetic part and the pre-positioning position of the workpiece is greater than or less than the current length of the suction cup clamp, the length of the suction cup clamp can be adjusted by the telescopic part 20; when the height of the installation space of the workpiece in the Y direction of the car is greater than or less than the current height of the suction cup clamp, the height of the suction cup clamp can be adjusted by the telescopic part 20; the above method can make the suction cup clamp suitable for more usage occasions.

[0047] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
