Description

Technical Field

[0001] This utility model belongs to the field of smartphone assembly technology, and specifically relates to a smartphone assembly structure. Background Technology

[0002] As a communication tool, smartphones are characterized by high performance and multiple functions, and are widely used in daily life and work. They play an increasingly important role in today's society. In the manufacturing process of smartphones, it is necessary to assemble the prepared parts.

[0003] Currently, because the bottom shells of existing smartphones are relatively thin, excessive force can easily be applied during clamping and fixing, causing damage to the bottom shell. Therefore, during the assembly of smartphones, it is often impossible to accurately position them. This leads to bugs caused by poor contact due to slight misalignment of components, reducing the lifespan of the smartphone.

[0004] Therefore, in view of the problem that the existing smartphone bottom shell is relatively thin and clamping fixation can easily lead to the shell cracking, a smartphone assembly structure with suction cups can be designed. Utility Model Content

[0005] To overcome the problem that the thinness of existing smartphone back covers makes it easy for the casing to crack when using clamping for fixation.

[0006] The technical solution of this utility model is as follows: a smartphone assembly structure, including an mounting plate; and a fixed suction cup. A phone bottom shell is placed on the assembly platform. Two opposing mounting plates are arranged on the front and rear sides of the phone bottom shell. Two opposing movable blocks are arranged between the two mounting plates. The bottom ends of the two movable blocks are provided with telescopic grooves. Telescopic rods are movably connected in the telescopic grooves. A fixed suction cup is fixedly connected to the bottom end of the telescopic rods. A first threaded rod is rotatably connected in the telescopic grooves. A first limiting post is fixedly connected in the telescopic grooves. A screw hole matching the first threaded rod is opened in the telescopic rod. The telescopic rod is sleeved on the outside of the first limiting post. A first knob is provided above the movable blocks. The first knob is fixedly connected to the first threaded rod.

[0007] Preferably, the first screw rod is rotated by the first knob. Under the restriction of the first limit post, the telescopic rod cannot rotate with the first screw rod. Instead, it drives the fixed suction cup to move downward along the telescopic groove. The fixed suction cup discharges the air and uses the pressure difference between the inside and outside to generate an adsorption force. The external atmospheric pressure presses the object tightly onto the surface of the suction cup to achieve adsorption.

[0008] Preferably, a limiting groove is provided in the telescopic groove, and a limiting slider is movably connected in the limiting groove. The limiting slider is fixedly connected to the outside of the telescopic rod.

[0009] Preferably, a No. 2 threaded rod is rotatably connected inside the mounting plate, and a No. 2 limiting post is fixedly connected to the side of the mounting plate near the bottom shell of the mobile phone. A screw hole matching the No. 2 threaded rod is opened on the moving block, and the moving block is sleeved on the outside of the No. 2 limiting post.

[0010] Preferably, a second knob is provided on the side of the mounting plate away from the bottom of the phone, and the second knob is fixedly connected to the second threaded rod.

[0011] Preferably, the No. 2 threaded rod has a No. 1 connecting groove, and a No. 1 connecting post is threadedly connected in the No. 1 connecting groove. A limiting ring located on the outside of the mounting plate is fixedly connected to the side of the No. 1 connecting post away from the No. 1 connecting groove.

[0012] Preferably, a second connecting groove is provided on the side of the second limiting post away from the mounting plate, and an extended limiting post is threaded into the second connecting groove.

[0013] Preferably, one side of the extended limiting post is fixedly connected to a second connecting post that matches the second connecting groove, and the other side of the extended limiting post is fixedly connected to a third connecting groove that matches the second connecting post.

[0014] The beneficial effects of this utility model are:

[0015] The telescopic rod moves downward in the telescopic groove, causing the fixed suction cup to move downward. The fixed suction cup expels air and uses the pressure difference between the inside and outside to generate an adsorption force. The external atmospheric pressure presses the object firmly onto the surface of the suction cup to achieve adsorption. This fixing method is relatively gentle and is less likely to damage the bottom of the phone, making it convenient for positioning when assembling other parts later. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment: a smartphone assembly structure, including an mounting plate 1; and a fixing suction cup 2. A phone bottom shell is placed on the assembly platform. Two opposing mounting plates 1 are arranged on the front and rear sides of the phone bottom shell. Two opposing movable blocks 3 are arranged between the two mounting plates 1. The bottom ends of the two movable blocks 3 are provided with telescopic grooves 4. Telescopic rods 5 are movably connected in the telescopic grooves 4. The bottom ends of the telescopic rods 5 are fixedly connected to the fixing suction cup 2. A first threaded rod 6 is rotatably connected in the telescopic grooves 4. A first limiting post 7 is fixedly connected in the telescopic grooves 4. A screw hole matching the first threaded rod 6 is opened in the telescopic rod 5. The telescopic rod 5 is sleeved on the outside of the first limiting post 7. A [missing information - likely a device or structure] is provided above the movable blocks 3. Knob 8 is fixedly connected to threaded rod 6. Knob 8 drives threaded rod 6 to rotate. Under the restriction of limit post 7, telescopic rod 5 cannot rotate with threaded rod 6. Instead, it drives fixed suction cup 2 to move downward along telescopic groove 4. Fixed suction cup 2 expels air and uses the pressure difference between inside and outside to generate suction force. External atmospheric pressure presses the object tightly onto the suction cup surface to achieve adsorption. Limiting groove 9 is opened in telescopic groove 4. Limiting slider 10 is movably connected in limiting groove 9. Limiting slider 10 is fixedly connected to the outside of telescopic rod 5. Limiting slider 10 and limiting groove 9 can limit the range of movement of telescopic rod 5 to prevent telescopic rod 5 from completely coming out of telescopic groove 4.

[0025] Please see Figure 1 , Figure 5 , Figure 6In this embodiment, a second threaded rod 11 is rotatably connected inside the mounting plate 1. A second limiting post 12 is fixedly connected to the side of the mounting plate 1 near the bottom of the phone casing. A screw hole matching the second threaded rod 11 is opened on the movable block 3. The movable block 3 is sleeved on the outside of the second limiting post 12. After the second threaded rod 11 rotates, under the restriction of the second limiting post 12, the movable block 3 screwed to the outside of the second threaded rod 11 moves along the second limiting post 12. The mounting plate 1 is set on the side away from the bottom of the phone casing. There is a second knob 13, which is fixedly connected to a second threaded rod 11. Rotating the second knob 13 drives the second threaded rod 11 to rotate, providing power for the rotation of the second threaded rod 11. The second threaded rod 11 has a first connecting groove 14, and a first connecting post 15 is threaded into the first connecting groove 14. A limiting ring 16 located on the outer side of the mounting plate 1 is fixedly connected to the side of the first connecting post 15 away from the first connecting groove 14. The limiting ring 16 is used to connect the two mounting plates 1. Plate 1 is fixed together, and limiting ring 16 is fixed through first connecting groove 14 and first connecting post 15 to limit the movement range of the phone bottom shell. Second limiting post 12 has second connecting groove 17 on the side away from mounting plate 1. Extending limiting post 18 is threaded into second connecting groove 17. The setting of extended limiting post 18 makes it easy to install moving block 3 between two mounting plates 1. One side of extended limiting post 18 is fixedly connected to second connecting post 19 that matches second connecting groove 17, and the other side of extended limiting post 18 is fixedly connected to third connecting groove 20 that matches second connecting post 19. The extension post 18 and second limiting post 12 are connected by screwing second extension post into second connecting groove 17. At the same time, second connecting post 19 is connected into second connecting groove 17 to connect extension limiting post 18 with extension limiting post 18. In this way, the distance between mounting plates 1 can be changed according to the size of the phone bottom shell, thereby limiting the phone bottom shell.

[0026] During installation, first place the phone bottom case on the assembly platform, then take out the mounting plate 1, take out two mounting plates 1, place them tightly against the front and back sides of the phone bottom case, then fix the mounting plate 1 on the assembly platform, then pass the moving block 3 through the second limiting post 12, then take out a threaded rod of appropriate length, pass it through the hole groove on the mounting plate 1, pass it through the screw hole on the moving block 3, then screw the first connecting post 15 into the first connecting groove 14, and fix the limiting ring 16 on the outside of the mounting plate 1 on the other side.

[0027] During assembly, the second threaded rod 11 is rotated according to the position of the assembled parts. Under the restriction of the second limiting post 12, the moving block 3 drives the fixed suction cup 2 to move along the second limiting post 12 and the extension limiting post 18. After moving to the appropriate position, the first knob 8 is rotated. The first knob 8 drives the first threaded rod 6 to rotate. Under the restriction of the first limiting post 7, the limiting slide groove 9 and the limiting slider 10, the telescopic rod 5 screwed to the outside of the first threaded rod 6 drives the fixed suction cup 2 to move downward along the telescopic groove 4. The air in the fixed suction cup 2 is expelled by squeezing. The suction force is generated by the pressure difference between the inside and outside. The external atmospheric pressure presses the bottom shell of the mobile phone onto the surface of the suction cup to achieve adsorption and fixation, which is convenient for subsequent assembly processing.

[0028] Through the above steps, the telescopic rod 5 moves downward in the telescopic groove 4, causing the fixed suction cup 2 to move downward. The fixed suction cup 2 expels air and uses the pressure difference between the inside and outside to generate an adsorption force. The external atmospheric pressure presses the object firmly onto the surface of the suction cup to achieve adsorption. This fixing method is relatively gentle and is less likely to damage the bottom shell of the phone. It is convenient for positioning when assembling other parts later, thus solving the problem that the bottom shell of existing smartphones is relatively thin and clamping fixation can easily cause the shell to crack.
