Description

Technical Field

[0001] This utility model belongs to the field of mobile phone holder technology, and in particular relates to a vacuum adsorption type mobile phone holder. Background Technology

[0002] As an auxiliary tool, a phone stand can help users fix their phone in a suitable position and angle, thereby freeing their hands and improving the user experience.

[0003] Chinese patent application No. 202510741532.9 discloses a folding suction cup mobile phone holder, including a base plate, a suction cup connected to the top of the base plate, a bolt fixedly installed on the top of the base plate, a knob movably installed on the top of the suction cup, a nut fixedly installed inside the knob, the nut threadedly engaging with the bolt, the suction cup being movably disposed outside the bolt through an opening, a support rod movably installed on the top of the suction cup, a folding rod movably connected to one side of the support rod, and a magnetic suction cup movably connected to the side of the folding rod away from the support rod.

[0004] In the above technical solution, vacuum adsorption is achieved through suction cups to ensure that the stand can be used stably in different environments. However, in the above technical solution, magnetic suction cups are needed to attach to the back of the phone to support and fix the phone. However, since magnetic suction cups need to be used with phones that have magnetic rings, they cannot be used with mid-to-low-end models that do not have magnetic rings, resulting in a narrow range of compatibility. In addition, the actual size of the magnetic suction cups occupies the space on the back of the phone, taking up the space required by the user when using wireless charging. Summary of the Invention

[0005] To address the shortcomings of existing technologies, a vacuum adsorption type mobile phone holder is provided.

[0006] This utility model is achieved using the following technical solution:

[0007] A vacuum-adhesive mobile phone holder includes a base. A support plate is pivotally connected to one end face of the base. The pivot is a damping shaft and is parallel to the end face. At least two support claws are arranged along the axial direction of the pivot near the support plate on the base. The support claws have a barbed structure and the barbs are inclined towards the support plate. An adjustment mechanism is provided inside the base to adjust the distance between the support claws and the pivot. The support plate and the support claws together form a support mechanism for supporting the mobile phone. A negative pressure mechanism is provided at the end of the base away from the support mechanism to fix the base to the mounting plane.

[0008] The negative pressure mechanism allows the base to be fixed in any position on a flat surface, and the accompanying support plate and support claws provide fixed support for the mobile phone, making it compatible with different mobile phone models.

[0009] Preferably, the base has a frustum-shaped structure, and a knob is rotatably provided on the outer circumferential surface of the base. The knob is coaxially arranged with the base. When the knob is rotated, the negative pressure mechanism retracts towards the inside of the base in the axial direction, and increases the space enclosed between the outer circumferential surface of the base and the mounting plane to form negative pressure.

[0010] By placing the knob on the outside, the torque required when the user rotates the knob is guaranteed, thus ensuring the pressure difference between the inside and outside generated by the negative pressure mechanism. This makes it more effortless compared to a small-radius knob placed in the center.

[0011] Preferably, the base includes a first housing, a second housing, and a third housing supported between the first and second housings arranged along its axial direction. The knob is sleeved on the outside of the third housing. A clearance groove for avoiding the support of the third housing is provided on the horizontal surface of the knob. The first housing is hollow inside, and the adjustment mechanism is located inside the first housing.

[0012] The third housing can be smaller than the diameter of the first and second housings, so that the knob can be located between the first and second housings in an embedded structure; the third housing can also be equal to the diameter of the first and second housings, so that the knob can be fitted together.

[0013] Preferably, the adjustment mechanism includes a slide table disposed in the first housing, the other end of the support claw relative to the barb is a connecting end, the connecting end passes through the first housing and is fixedly connected to the slide table, the first housing is provided with a limiting groove for the connecting end to slide, the first housing is provided with a limiting slide channel that fits into the slide table, and the first housing is provided with a stop for fixing the slide table.

[0014] The sliding table drives the support claw to slide synchronously, thereby adjusting the distance between the support claw and the support plate to accommodate mobile phones of different thicknesses and tilt angles.

[0015] Preferably, the first housing has an oblong hole located between the limiting slides, and the stop is a double-ended button located in the oblong hole. The double-ended button can lock or unlock by increasing the resistance between itself and the slide.

[0016] When the first end of the double-ended button is pressed, the double-ended button can lock the slide. When the second end of the double-ended button is pressed, the double-ended button rotates through a certain angle and changes the end face that is in contact with the slide, thereby unlocking the slide.

[0017] Preferably, the slide table has a toothed groove along the limiting sliding extension direction, the opening of the toothed groove faces the double-ended button, the double-ended button has a protrusion that extends into the toothed groove, and the protrusion has a toothed surface for meshing with the toothed groove.

[0018] By setting a toothed protrusion on the double-ended button, the friction between the double-ended button and the slide is changed into a supporting force, thereby further ensuring the stability of the slide after positioning.

[0019] Preferably, the first housing is provided with two ears for hinged connection of the two-ended buttons, and the two ears are provided with locking positions arranged along the rotation direction of the two-ended buttons.

[0020] The dual ears with locking positions allow the dual buttons to remain self-locking after switching, preventing the dual buttons from unlocking on their own and causing the slide to lose its restraint, making it difficult for the support claw to limit the phone.

[0021] Preferably, a spring is provided between the slide and the inner wall of the first housing to increase the preload between the slide and the double-ended button.

[0022] The spring can be a tension spring or a thrust spring. When the vector direction of the force generated by the spring is from the position of the support claw to the position of the support plate, the elastic force of the spring can be used to support the phone in the tilted state after the double-end buttons are unlocked, preventing the phone from losing its restraint on one side and sliding off on its own.

[0023] Preferably, the third housing has a radially recessed platform that abuts against the first housing. The platform has an annular structure and circumferentially arranged positioning holes. The first housing has a positioning pin that can extend and retract in the axial direction. The head of the positioning pin is inserted into the positioning hole, thereby enabling the first housing to rotate circumferentially.

[0024] Preferably, the end of the support claw near the support plate is provided with an elastic pad.

[0025] The elastic pad can be made of materials such as rubber or silicone, which have anti-slip and deformation capabilities.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] The device uses a negative pressure mechanism to install the base, making it compatible with platforms that cannot be held and fixed using traditional clamping mechanisms. This ensures a stable and secure hold. The device also uses support claws and support plates located on the front and rear sides of the upper part of the base to hold and fix the phone, avoiding taking up the space required for wireless charging and achieving compatibility between the fixing function and the wireless charging function.

[0037] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 — Figure 8As shown, this embodiment discloses a vacuum adsorption type mobile phone holder, including a base 10 with a frustum-shaped structure. The base 10 includes a first housing 11, a second housing 12, and a third housing 13 arranged sequentially from top to bottom along the axial direction. The first housing 11 includes a first upper cover 111 and a second upper cover 112 spaced apart, with an assembly space formed between the first upper cover 111 and the second upper cover 112. A support plate 15 is pivotally connected to the upper end face of the first upper cover 111. The pivot is a damping rotating shaft 14, which is parallel to the end face. Two support claws 16 are symmetrically arranged on the first upper cover 111 near the support plate 15 along the pivot axis. The support claws 16 have a barb-shaped structure and the barbs are inclined towards the support plate 15. The support plate 15 and the support claws 16 together form a support mechanism for supporting the mobile phone. An elastic pad is provided at the end of the support claw 16 near the support plate 15.

[0039] The third housing 13 is provided with a radially recessed platform 131, which abuts against the first housing 11. The platform 131 has an annular structure and is provided with circumferentially arranged positioning holes 24. The first housing 11 is provided with a positioning pin 25 that can extend and retract in the axial direction, and the head of the positioning pin 25 is embedded in the positioning hole 24.

[0040] An adjustment mechanism is provided in the assembly space to adjust the distance between the support claw 16 and the pivot. The lower end of the second housing 12 is provided with a negative pressure mechanism for fixing the base 10 on the mounting plane. A knob 30 is rotatably mounted on the outer circumferential surface of the third housing 13. The knob 30 is coaxially arranged with the base 10. When the knob 30 is rotated, the negative pressure mechanism retracts into the inner side of the base 10 in the axial direction, and increases the space enclosed between the outer circumferential surface of the base 10 and the mounting plane to form a negative pressure.

[0041] The second housing 12 has an internal space 26 for accommodating the negative pressure mechanism. A limiting slide 40 and a sliding table 18 are provided on the upper surface of the second housing 12. The sliding table 18 can engage with the limiting slide 40, allowing it to slide along the length of the limiting slide 40. A tension spring 23 is provided between the sliding table 18 and the inner wall of the first housing 11. The other end of the support claw 16 relative to the barb is a connecting end, which passes through the first housing 11 and is fixedly connected to the sliding table 18. Figure 7 As shown, the first housing 11 is provided with a limiting groove 41 for the connecting end to slide, and the position of the limiting groove 41 corresponds to the position of the support claw 16.

[0042] The first housing 11 is provided with a stop for fixing the slide 18. The first housing 11 is provided with an oblong hole 42 located between the limiting slides 40. The stop is a double-ended button 17 provided in the oblong hole 42. The first housing 11 is provided with double ears 20. The double-ended button 17 is hinged between the double ears 20 through a hinge shaft 171. The double ears 20 are provided with locking positions, including a first locking position 21 and a second locking position 22. The first locking position 21 and the second locking position 22 correspond to the locking position and unlocking position of the double-ended button 17, respectively. The first locking position 21 and the second locking position 22 are arranged along the rotation direction of the double-ended button 17. The two ends of the double-ended button 17 in the width direction are provided with locking rods 174 for locking into the locking positions.

[0043] A toothed groove 19 is provided inside the slide table 18 along the limiting sliding extension direction. The toothed groove 19 is located on one side of the slide table 18 in the width direction. The opening of the toothed groove 19 faces the double-ended button 17. The double-ended button 17 is provided with a protrusion 172 that extends into the toothed groove 19. The protrusion 172 is provided with a toothed surface 173 for meshing with the toothed groove 19.

[0044] The knob 30 includes a grip portion 31 located on the outside of the third housing 13 and a collar portion 32 located at the axial center. A horizontal portion 33 at the bottom is connected between the grip portion 31 and the collar portion 32. A clearance groove 34 for avoiding the support portion of the third housing 13 is provided in the horizontal portion 33. The support portion can be any existing fixed screw or support column structure that extends and supports in the axial direction. No limitation is made here. The negative pressure mechanism is a suction cup 27 coaxially arranged with the collar portion 32. The collar portion 32 is fitted on the back straight rod of the suction cup 27. Two sets of inclined slides 35 with a spiral upward trend are symmetrically arranged on the collar portion 32. A linkage rod is radially passed through the back straight rod of the suction cup 27. The two ends of the linkage rod are located in the two inclined slides 35.

[0045] When the gripping part 31 is rotated in the first direction, the gripping part 31 drives the collar part 32 to rotate in the first direction through the horizontal part 33. This allows the inner wall of the inclined slide 35 to abut against the linkage rod, causing the linkage rod to drive the straight rod on the back of the suction cup 27 to move upward along the axis. This causes the suction cup 27 to retract into the inner side of the base 10 within the movable space 26, thereby increasing the volume of the space enclosed by the suction cup 27, the second housing 12, and the mounting plane to create negative pressure, thus completing the fixed installation of the base 10. When it is necessary to remove the base 10, rotating the gripping part 31 in the second direction will drive the suction cup 27 to push outward, thereby reducing the volume of the space enclosed by the suction cup 27, the second housing 12, and the mounting plane, balancing the internal and external pressures. At this time, the base 10 is released from fixation.

[0046] When the double-ended button 17 is in the locked position, the locking rod 174 engages with the first locking position 21, and the double-ended button 17 moves the protrusion 172 to the lower limit position, thereby engaging the tooth surface 173 with the tooth groove 19. The double-ended button 17 then intercepts the slide table 18 by wedging it in the sliding direction, thus locking the slide table 18. When the double-ended button 17 is in the unlocked position, the locking rod 174 engages with the second locking position 22, and the double-ended button 17 moves the protrusion 172 to the upper limit position, thereby disengaging the tooth surface 173 from the tooth groove 19, thus releasing the lock on the slide table 18.
