Description

Technical Field

[0001] This utility model relates to the field of mobile phone holder technology, and its features include a vehicle-mounted mobile phone holder that can hide the power cord and adjust the direction in multiple directions. Background Technology

[0002] Currently, mobile devices such as smartphones have increasingly sophisticated communication, navigation, and multimedia functions, making them indispensable electronic products in people's lives. Especially for smartphones, for safety reasons, when users need to use their phones while driving and the phone is fixed to the car's center console, a car phone holder is required to secure it.

[0003] In existing technology, car phone holders typically include a phone clamp for holding the phone and a bracket body for supporting the phone clamp. The phone clamp is usually an electric phone clamp with a power cord, typically powered from the car's cigarette lighter socket via an adapter or from the car's USB socket. The bracket body is usually fixed to the windshield via a suction cup, or to the center console via a suction cup, or to the air vent grille via a vent clip, or to the rearview mirror via a clamp. Furthermore, to enable the phone clamp to steer (see Chinese patent documents CN208401615U and CN203267928U), some car phone holders have a steerable bracket body.

[0004] However, the existing car phone holders described above have the following technical problems: 1) The main body of a car phone holder usually only has the function of rotating to adjust the direction (e.g., CN203267928U), or only has the function of swinging up and down to adjust the direction (e.g., CN208401615U), and cannot enable the phone holder to have both its own rotation adjustment function and multi-directional rotation adjustment function around multiple axes at the same time. 2) The power cord of the car phone holder is separate from the holder body. The power cord is exposed and cannot be passed through and hidden inside the holder body. Especially when the holder body has a steering function, it is even more difficult for the power cord to pass through and be hidden in the pivot position of the holder body. The exposed power cord not only has a poor visual effect, but is also easy to get tangled and interfere with the holder body. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a car phone holder that can hide the power cord and adjust the direction in multiple directions, in order to address the shortcomings of the prior art. On the one hand, the car phone holder can enable the phone clamp to have its own rotation adjustment function and multi-directional rotation adjustment function around two axes. On the other hand, it can allow the power cord to pass through and be hidden inside the holder, avoiding the power cord from being exposed, and enabling the DC terminal to be electrically connected to the phone clamp.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a car phone holder that can hide the power cord and adjust the direction in multiple directions, including a phone clamp, a first bracket, a second bracket, a power plug, and a power cord. A first screw is installed between one end of the phone clamp and one end of the first bracket, and the phone clamp can rotate to adjust its direction based on the first screw. A first central hole is provided inside the first screw. A second screw is installed between the other end of the first bracket and the front end of the second bracket, and the first bracket can rotate to adjust its direction based on the second screw. A second central hole is provided inside the second screw. The rear end of the two brackets is rotatably connected to the front end of the power plug. The front end of the power plug is provided with a plug contact, and the rear end of the second bracket is provided with a bracket contact. The plug contact and the bracket contact engage to achieve electrical connection. The rear end of the power plug is provided with a DC terminal, and the DC terminal is electrically connected to the plug contact. The front end of the power cord is electrically connected to the mobile phone clamp, and the rear end of the power cord is electrically connected to the plug contact of the power plug. The power cord is sequentially passed through the mobile phone clamp, the first central hole of the first screw, the first bracket, the second central hole of the second screw, and the second bracket.

[0007] The beneficial effects of this utility model are: (1) Since a first screw is installed between the mobile phone clamp and one end of the first bracket, the mobile phone clamp can rotate and adjust its direction based on the first screw. Therefore, the mobile phone clamp itself can rotate and adjust its direction; Since a second screw is installed between the other end of the first bracket and the front end of the second bracket, the first bracket can rotate and adjust its direction based on the second screw. Therefore, the mobile phone clamp can rotate and adjust its direction with the first bracket, that is, the mobile phone clamp can rotate and adjust its direction with the first bracket around the axis of the second screw; Since the rear end of the second bracket The power plug is rotatably connected to the front end of the power plug. Therefore, the mobile phone clamp can rotate and adjust its direction with the rotation of the second bracket. That is, the mobile phone clamp can rotate and adjust its direction with the rotation axis between the second bracket and the power plug, thereby allowing the mobile phone clamp to rotate and adjust its direction in multiple directions. (2) In this utility model, the first screw has a first central hole, the second screw has a second central hole, the front end of the power plug has a plug contact, the rear end of the second bracket has a bracket contact, the plug contact and the bracket contact are in contact and cooperate to achieve electrical connection, the rear end of the power plug has a DC terminal, the DC terminal is electrically connected to the plug contact, the front end of the power cord is electrically connected to the mobile phone clamp, the rear end of the power cord is electrically connected to the plug contact of the power plug, and the power cord is sequentially passed through the mobile phone clamp, the first central hole of the first screw, the first bracket, the second central hole of the second screw, and the second bracket. Therefore, this utility model can make the power cord pass through and hide inside the bracket, avoid the power cord being exposed, and make the DC terminal electrically connected to the mobile phone clamp.

[0008] In the above technical solution, a first screw positioning sleeve is installed outside the front end of the first screw, a screw positioning hole is provided at one end of the first bracket, the rear end of the first screw positioning sleeve is installed inside the screw positioning hole and positioned by the screw positioning hole, a first disc body is provided outside the front end of the first screw positioning sleeve, and a disc sleeve is provided at the rear end of the mobile phone clamp, the disc sleeve being rotatably fitted onto the first disc body; the first central hole is axially located inside the front end of the first screw, and a first side hole communicating with the first central hole is also provided on the side of the first screw, the power cord passing outward from the first central hole of the first screw through the first side hole and the first screw positioning sleeve. This utility model can position the first screw positioning sleeve through the screw positioning hole of the first bracket, and then position the first screw through the first screw positioning sleeve, thereby preventing the first screw from rotating inside the first bracket. Therefore, when the power cord passes outward from the first central hole of the first screw through the first side hole and the first screw positioning sleeve, the power cord will not twist, avoiding the problem of the power cord twisting due to the rotation of the mobile phone clamp. This invention enables the mobile phone clamp to rotate by the cooperation between the disc sleeve and the first disc body.

[0009] In the above technical solution, the rear end of the first screw extends rearward from the screw positioning hole of the first bracket, and a first knob nut is screwed onto the rear end of the first screw. The first knob nut is used to lock or loosen the first disc body and the disc sleeve. When the first knob nut is loosened, the first disc body and the disc sleeve are released from each other, allowing the phone clamp to rotate. When the first knob nut is tightened, the first disc body and the disc sleeve are locked together, preventing the phone clamp from rotating.

[0010] In the above technical solution, a second screw positioning sleeve is installed outside one end of the second screw, and a second disc is provided outside one end of the second screw positioning sleeve. The second disc is mounted on the second bracket, and disc teeth are provided on the outer side of the second disc. A sleeve is provided at the other end of the second screw positioning sleeve, and a shaft hole is provided at the other end of the first bracket. The shaft hole is rotatably fitted onto the sleeve. The second central hole is axially located inside one end of the second screw, and a second side hole communicating with the second central hole is also provided on the side of the second screw. The power cable passes outward from the second central hole of the second screw through the second side hole and the second screw positioning sleeve. The second bracket of this utility model can fix the second screw positioning sleeve, and then the second screw is positioned by the second screw positioning sleeve, thereby preventing the second screw from rotating inside the second bracket, thereby preventing the power cable from twisting due to the rotation of the second screw. Since the shaft hole of the first bracket is rotatably fitted onto the sleeve of the second screw positioning sleeve, the first bracket can rotate based on the second screw positioning sleeve on the second screw. The second bracket has a limiting surface to limit the maximum rotation angle of the first bracket, thus preventing the power cord from breaking due to excessive rotation of the first bracket.

[0011] In the above technical solution, the outer side of the first bracket is provided with bracket retaining teeth, which are positioned opposite to the disc retaining teeth. The other end of the second screw extends outward from the shaft hole of the second bracket, and a second knob nut is screwed onto the rear end of the second screw. The second knob nut is used to lock or loosen the bracket retaining teeth and the disc retaining teeth. When the second knob nut is loosened, the bracket retaining teeth and the disc retaining teeth are disengaged, allowing the first bracket to rotate. When the second knob nut is tightened, the bracket retaining teeth and the disc retaining teeth are locked together, preventing the first bracket from rotating.

[0012] In the above technical solution, the plug contact of the power plug includes a copper shaft and a copper ring, and the bracket contact of the second bracket includes a first elastic pin and a second elastic pin. The first elastic pin is in elastic contact with the copper shaft, and the second elastic pin is in elastic contact with the copper ring. When the second bracket rotates, the first elastic pin can always be in elastic contact with the copper shaft to always achieve electrical connection, while the second elastic pin can rotate on the side of the copper ring to always achieve electrical connection.

[0013] In the above technical solution, a third screw is provided between the power plug and the second bracket. The front end of the third screw is screwed into the rear end of the second bracket. The rear end of the second bracket is provided with a fixing plate, which fixes the front end of the third screw. The rear end of the third screw has a threadless section, and the front end of the power plug has a rotating plate, which is rotatably fitted onto the threadless section of the third screw. The rear end of the third screw is provided with a nut to prevent the rotating plate from loosening backward. This utility model enables the power plug and the second bracket to rotate relative to each other by rotating the rotating plate on the threadless section of the third screw, and prevents the power plug from becoming detached from the second bracket.

[0014] In the above technical solution, the third screw has a third central hole in the axial direction, and the first elastic pin is installed inside the third central hole. This structure enables the first elastic pin to be located at the axial center of the third screw, ensuring that the first elastic pin is aligned with the axis of the copper shaft, resulting in stable and reliable rotation, and facilitating the connection of the other end of the copper shaft to a DC terminal.

[0015] In the above technical solution, a washer is provided between the fixed plate and the rotating plate, and the washer is fitted onto the third screw. By setting the washer, the rotating plate generates a damping effect when rotating. Therefore, when the user needs to rotate the second bracket, a little force is required to overcome the damping effect of the washer. When the user removes the rotation force, the second bracket and the power plug can be positioned still by the damping effect of the washer.

[0016] In the above technical solution, the DC terminal includes a terminal contact piece, a terminal contact cylinder, and an insulating cylinder. The terminal contact piece is installed inside the insulating cylinder, and the terminal contact cylinder is installed outside the insulating cylinder. The rear end of the copper shaft is screwed to the terminal contact cylinder. A copper shaft hole is provided inside the copper shaft hole, and a wire is passed through the copper shaft hole. One end of the wire extends into the insulating cylinder and is connected to the terminal contact piece, and the other end of the wire is connected to a copper ring. The DC terminal of this utility model is used to plug into a DC socket on the center console of an automobile. Attached Figure Description

[0027] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-10 As shown, this utility model is a car phone holder that can hide the power cord and adjust the direction in multiple directions. It includes a phone clamp 1, a first bracket 2, a second bracket 3, a power plug 4, and a power cord 5. A first screw 6 is installed between one end of the phone clamp 1 and the first bracket 2, allowing the phone clamp 1 to rotate and adjust its direction based on the first screw 6. A first central hole 61 is provided inside the first screw 6. A second screw 7 is installed between the other end of the first bracket 2 and the front end of the second bracket 3, allowing the first bracket 2 to rotate and adjust its direction based on the second screw 7. A second central hole 71 is provided inside the second screw 7. The rear end of the second bracket 3... The power cord 5 is rotatably connected to the front end of the power plug 4, the front end of the power plug 4 is provided with a plug contact, and the rear end of the second bracket 3 is provided with a bracket contact. The plug contact and the bracket contact are in contact and cooperate to achieve electrical connection. The rear end of the power plug 4 is provided with a DC terminal 41, and the DC terminal 41 is electrically connected to the plug contact. The front end of the power cord 5 is electrically connected to the mobile phone clamp 1, and the rear end of the power cord 5 is electrically connected to the plug contact of the power plug 4. The power cord 5 is sequentially passed through the mobile phone clamp 1, the first central hole 61 of the first screw, the first bracket 2, the second central hole 71 of the second screw, and the second bracket 3.

[0029] In this invention, because a first screw 6 is installed between one end of the phone clamp 1 and the first bracket 2, the phone clamp 1 can rotate and adjust its direction based on the first screw 6. Therefore, the phone clamp 1 itself can rotate and adjust its direction. In this invention, because a second screw 7 is installed between the other end of the first bracket 2 and the front end of the second bracket 3, the first bracket 2 can rotate and adjust its direction based on the second screw 7. Therefore, the phone clamp 1 can rotate and adjust its direction along with the first bracket 2, that is, the phone clamp 1 can rotate and adjust its direction around the axis of the second screw 7 along with the first bracket 2. In this invention, because the rear end of the second bracket 3 is connected to the power plug 4... The front ends are rotatably connected, therefore, the phone clamp 1 can rotate and adjust its direction as the second bracket 3 rotates. That is, the phone clamp 1 can rotate and adjust its direction around the rotation axis between the second bracket 3 and the power plug 4, thereby allowing the phone clamp 1 to rotate and adjust its direction in multiple directions. In this invention, the first screw 6 has a first central hole 61, the second screw 7 has a second central hole 71, the front end of the power plug 4 has a plug contact, and the rear end of the second bracket 3 has a bracket contact. The plug contact and the bracket contact engage to achieve electrical connection. The rear end of the power plug 4 has a DC terminal 41. The DC terminal 41 is electrically connected to the plug contact, the front end of the power cord 5 is electrically connected to the mobile phone holder 1, and the rear end of the power cord 5 is electrically connected to the plug contact of the power plug 4. The power cord 5 passes through the mobile phone holder 1, the first hole 61 of the first screw 6, the first bracket 2, the second hole 71 of the second screw 7, and the second bracket 3 in sequence. Therefore, this utility model can make the power cord 5 pass through and hide inside the mobile phone holder, avoid the power cord 5 being exposed to the outside, and make the DC terminal 41 electrically connected to the mobile phone holder 1.

[0030] like Figure 2 , Figure 4 and Figure 5As shown, a first screw positioning sleeve 8 is installed outside the front end of the first screw 6. One end of the first bracket 2 is provided with a screw positioning hole 21. The rear end of the first screw positioning sleeve 8 is installed inside the screw positioning hole 21 and is positioned by the screw positioning hole 21. A first disc body 81 is provided outside the front end of the first screw positioning sleeve 8. A disc sleeve 101 is provided at the rear end of the mobile phone clamp 1. The disc sleeve 101 is rotatably fitted onto the first disc body 81. The first central hole 61 is axially located inside the front end of the first screw 6. The side of the first screw 6 is also provided with a first side hole 62 communicating with the first central hole 61. The power cord 5 passes out of the first central hole 61 of the first screw 6 and through the first side hole 62 and the first screw positioning sleeve 8. This invention can position the first screw positioning sleeve 8 through the screw positioning hole 21 of the first bracket 2, and then position the first screw 6 through the first screw positioning sleeve 8, thereby preventing the first screw 6 from rotating within the first bracket 2. Therefore, when the power cord 5 passes outward from the first central hole 61 of the first screw 6 through the first side hole 62 and the first screw positioning sleeve 8, the power cord 5 will not twist, avoiding the problem of the power cord 5 twisting due to the rotation of the mobile phone clamp 1. This invention enables the mobile phone clamp 1 to rotate on its own through the cooperation of the disc sleeve 101 and the first disc body 81.

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the rear end of the first screw 6 extends rearward from the screw positioning hole 21 of the first bracket 2, and a first knob nut 9 is screwed onto the rear end of the first screw 6. The first knob nut 9 is used to lock or loosen the first disc body 81 and the disc sleeve 101. In this invention, when the first knob nut 9 is loosened, the first disc body and the disc sleeve 101 are released from each other, and the mobile phone clamp 1 can be rotated. When the first knob nut 9 is tightened, the first disc body and the disc sleeve 101 are locked together, and the mobile phone clamp 1 cannot be rotated.

[0032] like Figure 2 , Figure 6 and Figure 7As shown, a second screw positioning sleeve 10 is installed outside one end of the second screw 7. A second disc 102 is provided outside one end of the second screw positioning sleeve 10. The second disc 102 is mounted on the second bracket 3, and disc retaining teeth 103 are provided on the outer side of the second disc 102. A sleeve 104 is provided at the other end of the second screw positioning sleeve 10. A shaft hole 22 is provided at the other end of the first bracket 2, and the shaft hole 22 is rotatably fitted onto the sleeve 104. The second central hole 71 is axially located inside one end of the second screw 7. A second side hole 72 communicating with the second central hole 71 is also provided on the side of the second screw 7. The power cord 5 passes out of the second central hole 71 of the second screw 7 and through the second side hole 72 and the second screw positioning sleeve 10. The second bracket 3 of this utility model can fix the second screw positioning sleeve 10, and then the second screw 7 is positioned by the second screw positioning sleeve 10, thereby preventing the second screw 7 from rotating inside the second bracket 3, thereby preventing the power cord 5 from twisting due to the rotation of the second screw 7. Because the shaft hole 22 of the first bracket 2 is rotatably fitted onto the sleeve 104 of the second screw positioning sleeve 10, the first bracket 2 can rotate based on the second screw positioning sleeve 10 on the second screw 7. A limiting surface 31 is provided on the second bracket 3 to limit the maximum rotation angle of the first bracket 2 and prevent the power cord 5 from being twisted and broken due to excessive rotation of the first bracket 2.

[0033] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the outer side of the first bracket 2 is provided with bracket retaining teeth 23, which are positioned opposite to the disc retaining teeth 103. The other end of the second screw 7 extends outward from the shaft hole 22 of the second bracket 3, and a second knob nut 11 is screwed onto the rear end of the second screw 7. The second knob nut 11 is used to lock or loosen the bracket retaining teeth 23 and the disc retaining teeth 103. In this invention, when the second knob nut 11 is loosened, the bracket retaining teeth 23 and the disc retaining teeth 103 are disengaged, and the first bracket 2 can be rotated. When the second knob nut 11 is tightened, the bracket retaining teeth 23 and the disc retaining teeth 103 are locked together, and the first bracket 2 cannot be rotated.

[0034] like Figure 1-3 As shown in Figures 8-10, the plug contact of the power plug 4 includes a copper shaft 12 and a copper ring 13, and the bracket contact of the second bracket 3 includes a first elastic pin 14 and a second elastic pin 15. The first elastic pin 14 is in elastic contact with the copper shaft 12, and the second elastic pin 15 is in elastic contact with the copper ring 13. When the second bracket 3 rotates, the first elastic pin 14 can always be in elastic contact with the copper shaft 12 to always achieve electrical connection, while the second elastic pin 15 can rotate on the side of the copper ring 13 to always achieve electrical connection.

[0035] like Figure 2 , 3 As shown in Figures 8-10, a third screw 16 is provided between the power plug 4 and the second bracket 3. The front end of the third screw 16 is screwed into the rear end of the second bracket 3. A fixing plate 17 is provided at the rear end of the second bracket 3, which fixes the front end of the third screw 16. The rear end of the third screw 16 has a threadless section 162. The front end of the power plug 4 has a rotating plate 18, which is rotatably fitted onto the threadless section 162 of the third screw 16. The rear end of the third screw 16 has a nut 163 to prevent the rotating plate 18 from loosening. This utility model allows the power plug 4 and the second bracket 3 to rotate relative to each other by rotating the rotating plate 18 on the threadless section 162 of the third screw 16, and prevents the power plug 4 from loosening from the second bracket 3.

[0036] like Figure 2 , 3 As shown in Figures 8-10, the third screw 16 has a third central hole 161 in the axial direction, and the first elastic pin 14 is installed inside the third central hole 161. This structure enables the first elastic pin 14 to be located at the axial center of the third screw 16, so that the first elastic pin 14 is aligned with the axis of the copper shaft 12, ensuring stable and reliable rotation, and making it easy to connect the other end of the copper shaft 12 to the DC terminal 41.

[0037] like Figure 2 , 3 As shown in Figures 8-10, a washer 19 is provided between the fixed plate 17 and the rotating plate 18, and the washer 19 is fitted onto the third screw 16. By setting the washer 19, the rotating plate 18 generates a damping effect when rotating. Therefore, when the user needs to rotate the second bracket 3, a little force is required to overcome the damping effect of the washer 19. When the user removes the rotation force, the second bracket 3 and the power plug 4 can be positioned still by the damping effect of the washer.

[0038] like Figure 2 , 3As shown in Figures 8-10, the DC terminal 41 includes a terminal contact piece 411, a terminal contact cylinder 412, and an insulating cylinder 413. The terminal contact piece 411 is installed inside the insulating cylinder 413, and the terminal contact cylinder 412 is installed outside the insulating cylinder 413. The rear end of the copper shaft 12 is screwed to the terminal contact cylinder 412. The copper shaft 12 has a copper shaft hole 121 inside, and a wire (not shown in the figure) passes through the copper shaft hole 121. One end of the wire extends into the insulating cylinder 413 and is connected to the terminal contact piece 411, and the other end of the wire is connected to the copper ring 13. The DC terminal 41 of this invention is used to be plugged into a DC socket on the center console of an automobile. The DC terminal 41 of this invention has an external thread 414 and a handle 415. By rotating the handle, the external thread of the DC terminal 41 can be screwed into the external thread inside the DC socket, thereby fixing the power plug 4.

[0039] like Figure 1 and Figure 2 As shown, the first bracket 2 is L-shaped, the axis of the first screw 6 is perpendicular to the axis of the second screw 7, and the axis of rotation between the second bracket 3 and the power plug 4 is perpendicular to the axis of the second screw 7.

[0040] The above description is merely a preferred embodiment of this utility model. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
