Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, and in particular to an electronic device mounting bracket. Background Technology

[0002] Conventional phone holders include suction cups or adhesive layers for attaching to flat surfaces. Some users attach these traditional phone holders to dashboard surfaces to browse their phones in the car without holding them. However, vehicles frequently experience sudden acceleration, braking, and steering, causing the phone holder to lose its secure grip and easily fall off. Therefore, existing phone holders have limited applicability; the suction cups or adhesive layers are only suitable for attaching to flat surfaces. Utility Model Content

[0003] In view of this, the present invention provides an electronic device mounting bracket that can be stably attached to the surface of non-planar objects and has a wider range of applicable environments.

[0004] The electronic device mounting bracket of this utility model includes a frame unit, multiple contact surfaces and multiple mounting bases, with each of the contact surfaces and mounting bases connected in a one-to-one correspondence, and each mounting base connected to the frame unit; at least one of the mounting bases is a movable base, which is connected to the frame unit through a multi-degree-of-freedom rotation joint.

[0005] This invention relates to an electronic device mounting bracket that can be attached to a single plane via multiple contact surfaces, or simultaneously to a curved surface via multiple contact surfaces. By moving a movable base, the position and orientation of the contact surfaces connected to the movable base can be changed, allowing different contact surfaces to have different positions and orientations. This enables multiple contact surfaces to be securely attached to different positions on a non-planar object surface, such as a curved surface of an instrument panel. The multi-degree-of-freedom rotation joints allow the contact surfaces to rotate with multiple degrees of freedom relative to the bracket unit, thus making the position and orientation changes of the contact surfaces more diverse. The applicable environment of the electronic device mounting bracket is extended to object surfaces of various shapes. In actual use, by moving the movable base, each contact surface can reach its optimal orientation state, which is the state where the contact surface of the contact surface has the largest area.

[0012] In some embodiments, a locking part is also included, which is capable of switching back and forth between a locked position and a released position. The locking part is fixedly connected to the movable base and the frame unit when the locked position is engaged, and disengaged from the movable base and / or the frame unit when the released position is engaged.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] This utility model provides an electronic device mounting bracket that can be fixed to an object surface and replaces the user's hands in carrying the electronic device, allowing the user to browse the electronic device. (See also...) Figures 1-2 The electronic device mounting bracket includes a frame unit 10, a support unit 20, a mounting base 32, and a contact surface 31. The frame unit 10 supports the support unit 20, which in turn supports the electronic device. The mounting base 32 is connected to the frame unit 10, and the contact surface 31 is disposed on the mounting base 32 and used to attach to the surface of an object. Under user control, the support unit 20 can move relative to the frame unit 10, thereby moving the electronic device and changing its angle so that the user can adjust the angle of the electronic device to the most suitable viewing position.

[0030] In some embodiments, the bonding surface 31 includes a cup-shaped suction cup 3111, which forms a low-pressure sealed space with the object surface, thereby allowing the suction cup 3111 to adhere tightly to the object surface under external atmospheric pressure. In other embodiments, the bonding surface 31 includes an adhesive layer with adhesive properties, which can adhere tightly to the object surface. In still other embodiments, the bonding surface 31 includes a magnetic clasp, which can adhere tightly to a magnetic object surface. It is understood that the bonding surface 31 may also include any two or all of the suction cup 3111, the adhesive layer, and the magnetic clasp.

[0031] For ease of description, the surface on the adhesive surface 31 used to adhere to the object surface will be referred to as the adhesive surface, and the surface to which the adhesive surface 31 is adhered will be referred to as the object surface. For each individual adhesive surface 31, its adhesive surface can be a plane or a curved surface. Preferably, the adhesive surface of each individual adhesive part is a plane, and the object surface can be a plane or a curved surface.

[0032] Specifically, in some embodiments, there are multiple mounting bases 32 and contact surfaces 31, which are connected one-to-one. The frame unit 10 is connected to one end of the mounting base 32, and the mounting base 32 extends outward from the frame unit 10. The contact surfaces 31 are located at the other end of the mounting base 32 that is relatively far away from the frame unit 10. Different mounting bases 32 extend in different directions. With this arrangement, the contact surfaces 31 are far apart from each other, and the distance between any two contact surfaces 31 is greater. Multiple contact positions with greater distances are formed between the contact surfaces 31 and the object surface, thereby improving the stability of the electronic device mounting bracket on the object surface and its ability to resist external interference.

[0033] The electronic device mounting bracket of this utility model can be a mobile phone bracket, a tablet bracket, a camera bracket, etc. This utility model does not limit the specific type of electronic device held by the holding unit 20. In addition, unlike traditional mobile phone brackets or traditional tablet brackets that can only be fixed on a single plane, this utility model does not limit the specific type of object surface. The contact surface 31 can be attached to a flat object surface or a curved object surface, and can be attached to curved object surfaces with different degrees of curvature and different shapes. The object surface can be a desktop, a glass surface, a dashboard surface, etc.

[0034] Specifically, among the multiple mounting bases 32, there is at least one movable base 321, and among the multiple contact surfaces 31, there is at least one movable contact portion 311 connected to the movable base 321. The movable base 321 is independently rotatably connected to the frame unit 10, meaning that each movable base 321 can be manipulated by the user to rotate independently relative to the frame unit 10, and the rotation angle and direction of each movable base 321 are not affected by other mounting bases 32. Each movable base 321 is connected to the frame unit 10 through a multi-degree-of-freedom rotational joint, and the movable base 321 can rotate relative to the frame unit 10 with multiple degrees of freedom. With this configuration, when any movable base 321 rotates relative to the frame unit 10, the contact surface of the movable contact portion 311 provided on the movable base 321 can undergo various different forms of pose and orientation changes.

[0035] With the above settings, the electronic device mounting bracket of this utility model is not limited to any particular environment. The contact surface 31 can be attached to the flat surface of objects such as desks and office desks, as well as the flat surface of objects such as doors, windows, refrigerators, and walls. It can also be attached to any curved surface, such as the surface of an instrument panel. The user can selectively move the movable base 321 to selectively change the position and orientation of the movable contact part 311, thereby selectively changing the position and orientation of the surface to which it is attached. This allows different surfaces to have different positions and orientations. In actual use, the movable base 321 can be moved to bring each contact surface 31 to its optimal orientation state. The optimal orientation state of the contact surface 31 is when the contact surface 31 contacts the object surface to the maximum extent.

[0036] See Figures 1-2 , Figure 5 In some embodiments, the multi-degree-of-freedom rotary joint includes a hinge 323, a movable base 321 including a support arm 322, the support arm 322 including a supporting end 3221 and a movable end 3222, the supporting end 3221 and the movable end 3222 being the two ends of the support arm 322, the supporting end 3221 having a movable fitting portion 311, the hinge 323 connecting the movable end 3222 to the frame unit 10, and at least one of the movable end 3222 and the frame unit 10 forming a spherical pair with the hinge 323. Preferably, the hinge 323 is a spherical hinge with a ball head, and the support arm 322 is configured to rotate about the center of the sphere of the hinge 323. With this configuration, each movable base 321 has an infinite number of rotation axes, all of which pass through the center of the ball head. The center of the ball is the rotation center of the movable base 321 relative to the frame unit 10. Each movable base 321 can rotate in three degrees of freedom relative to the frame unit 10, and the pose and orientation of the contact surface 31 can be transformed in a more diverse manner, further expanding the types of object surfaces that the electronic device mounting bracket is applicable to.

[0037] Optionally, all mounting bases 32 are movable bases 321 rotatably connected to the frame unit 10, and all contact surfaces 31 are movable contact parts 311 connected to the movable bases 321. This invention does not limit the number of movable bases 321 and movable contact parts 311. Figures 1-2 , Figure 5 As shown, the frame unit 10 includes a first column 11 and a second column 12 arranged side by side. The side of the first column 11 facing away from the second column 12 forms a first facade 111, and the side of the second column 12 facing away from the first column 11 forms a second facade. There are two movable bases 321 and two movable fitting parts 311. The two movable bases 321 are rotatably connected to the first facade 111 and the second facade through hinges 323, respectively. The support arms 322 of the two movable bases 321 extend outward from the frame unit 10 in opposite directions.

[0038] Furthermore, in some embodiments, the electronic device mounting bracket also includes a locking part 33 that can reciprocate between a locked position and a released position. When the locking part 33 is in the locked position, the locking part 33 is fixedly connected to the movable base 321 and the frame unit 10 and restricts the rotational degree of freedom of the movable base 321 relative to the frame unit 10; when the locking part 33 is in the released position, the locking part 33 disengages from the movable base 321 and / or the frame unit 10, at which time the rotational degree of freedom between the movable base 321 and the frame unit 10 is released, thereby allowing the movable base 321 to rotate. With this configuration, the user can adjust the locking part 33 to the released position before the contact part 31 is attached to the object surface, so that the movable base 321 can rotate relative to the frame unit 10 and help the movable contact part 311 quickly find the optimal orientation. After the contact part rotates with the movable base 321 to reach the optimal orientation, the user can adjust the locking part 33 from the released position to the locked position. After that, the movable base 321 cannot rotate relative to the frame unit 10, and the movable contact part 311 and the object surface can remain relatively fixed for a long time. This avoids the frame unit 10 from accidentally rotating relative to the movable base 321 and the dashboard due to acceleration, braking or steering when the vehicle is in motion, and reduces the risk of electronic equipment falling off the holding unit 20.

[0039] Specifically, such as Figure 3 As shown, in some embodiments, the multi-degree-of-freedom rotary joint includes a hinge 323 and a deformable support 13. The hinge 323 is a ball joint located on the movable base 321, and the support 13 may specifically be a joint protruding from the base. Figures 1-2 , Figure 5The first elevation 111 and the boss on the second elevation are shown. The end of the support 13 has a first connecting groove 131 for accommodating the hinge 323. When the outer periphery of the support 13 is subjected to pressure, the support 13 will contract and deform, compressing the first connecting groove 131. A part of the hinge 323 is accommodated in the first connecting groove 131 and can rotate in three degrees of freedom relative to the support 13. The movable end 3222 of the support arm 322 is fixedly connected to the side of the hinge 323 facing away from the support 13.

[0040] When the locking part 33 is in the locked position, the locking part 33 applies pressure to the outer periphery of the support 13, and the support 13 deforms to cause the first connecting groove 131 to contract. At this time, the hinge 323 and the inner wall of the first connecting groove 131 are fixedly engaged, and the support arm 322 cannot rotate relative to the frame unit 10 around the center of the hinge 323. When the locking part 33 is in the released position, the locking part 33 disengages from the side of the support 13. At this time, the pressure of the locking part 33 on the support 13 is removed, the first connecting groove 131 expands, and the degree of freedom of the hinge 323 to rotate in the first connecting groove 131 is restored. Therefore, the support arm 322 can rotate around the center of the hinge 323.

[0041] Optionally, the locking part 33 can be sleeved on the support 13 and threadedly connected to the support 13. The locking part 33 and the support 13 are locked together by the threaded engagement. Figure 3 As shown by arrow V1, the locking part 33 can move in the direction of arrow V1, that is, it can reciprocate between the locked position and the released position. When the locking part 33 is in the locked position, it is sleeved on the outer periphery of the support 13 to press against the first connecting groove 131. When the locking part 33 is in the released position, as shown by arrow V1, it can move in the direction of arrow V1. Figure 3 As shown, at this time, the locking part 33 disengages from the support 13 and is fitted onto the support arm 322. It can be understood that in other embodiments, the locking part 33 may also be a movable clamp or sleeve fitted onto the support 13.

[0042] like Figure 4 As shown, in some embodiments, the multi-degree-of-freedom rotary joint includes a hinge 323 and a deformable movable end 3222. The frame unit 10 also includes a support 13, which may be protruding from the frame. Figures 1-2 , Figure 5 The first elevation 111 and the boss on the second elevation are shown. The hinge 323 is a ball joint hinge provided on the support 13. The movable end 3222 is formed at the other end of the support arm 322 that is relatively far away from the supporting end 3221. The movable end 3222 has a second connecting groove 3223 for accommodating the hinge 323. When the outer periphery of the movable end 3222 is subjected to pressure, the movable end 3222 will contract and deform and compress the second connecting groove 3223. A part of the hinge 323 is accommodated in the second connecting groove 3223 and can rotate in three degrees of freedom relative to the support arm 322. The support 13 is fixedly connected to the side of the hinge 323 opposite to the support arm 322.

[0043] When the locking part 33 is in the locked position, the locking part 33 applies pressure to the outer periphery of the movable end 3222. The deformation of the movable end 3222 causes the second connecting groove 3223 to contract. At this time, the hinge 323 and the inner wall of the second connecting groove 3223 are fixedly engaged, and the support arm 322 cannot rotate relative to the frame unit 10 around the center of the hinge 323. When the locking part 33 is in the released position, the locking part 33 disengages from the movable end 3222 of the support arm 322. At this time, the pressure of the locking part 33 on the outer periphery of the movable end 3222 is removed, the second connecting groove 3223 expands, and the degree of freedom of the hinge 323 to rotate within the second connecting groove 3223 is restored. Therefore, the support arm 322 can rotate around the center of the hinge 323.

[0044] Optionally, the locking part 33 is sleeved on the support arm 322 and threadedly connected to the support arm 322. The thread of the support arm 322 is located on the outer periphery of the movable end 3222. The locking part 33 and the support arm 322 are locked together by the threaded engagement. Figure 4 As shown by arrow V2, the locking part 33 moves in the direction of arrow V2, reciprocating between the locked and released positions. When the locking part 33 is in the locked position, as... Figure 4 As shown, the locking part 33 is sleeved on the outer periphery of the movable end 3222 to press against the second connecting groove 3223. When the locking part 33 is in the released position, the locking part 33 disengages from the outer periphery of the movable end 3222. In other embodiments, the locking part 33 may also be a movable clamp or sleeve sleeved on the support arm 322.

[0045] In some embodiments, the electronic device mounting bracket also includes an auxiliary loading member 34 disposed on the movable base 321. The auxiliary loading member 34 can be switched back and forth between a pressing position and a depressurizing position under user operation. When the auxiliary loading member 34 is in the pressing position, it presses the contact surface 31 to make the contact surface 31 fit tightly against the object surface. When the auxiliary loading member 34 is in the depressurizing position, it disengages from the contact surface 31. This configuration allows the user to indirectly apply pressure to the contact surface 31 through the auxiliary loading member 34, reducing the difficulty of operation. When the contact surface 31 is a suction cup 3111, the auxiliary loading member 34 can squeeze out the air between the suction cup 3111 and the object surface.

[0046] See Figures 1-2 , Figure 5In some embodiments, the auxiliary loading member 34 includes a pressing end 341 and a loading end 342. The movable base 321 includes a pin 35 disposed on the support arm 322, which passes between the pressing end 341 and the loading end 342. The auxiliary loading member 34 can thus rotate relative to the support arm 322 about the pin 35. The pressing end 341 is used to contact and press the contact surface 31, and the loading end 342 allows the user to apply force. The distance from the loading end 342 to the pin 35 is greater than the distance from the pressing end 341 to the pin 35. With this configuration, the auxiliary loading member 34 is equivalent to a lever, the pin 35 is equivalent to a fulcrum, and the pressing end 341 and the loading end 342 are respectively equivalent to the resistance force receiving part and the power force receiving part. The user can thus achieve contact between the contact surface 31 and the object surface through the lever principle. This makes it easier for the user to manipulate the auxiliary loading member 34, reducing finger pain.

[0047] See Figure 7 In some embodiments, the holding unit 20 includes a holding plate 21, a first clamping block 231, a second clamping block 232, a lead screw 24, and a first rotating wheel 25. The electronic device can be fixedly attached to the holding plate 21. The lead screw 24 is rotatably mounted on the holding plate 21. The lead screw 24 includes a first threaded section 241 and a second threaded section 242 arranged coaxially. The first threaded section 241 and the second threaded section 242 have threads with opposite directions of rotation. The first clamping block 231 and the first threaded section 241 are threadedly engaged, and the second clamping block 232 and the second threaded section 242 are threadedly engaged. The first clamping block 231 and the second clamping block 232 are both slidably connected to the holding plate 21, forming a clamping gap between them. One end of the lead screw 24 is fixedly connected to the first rotating wheel 25.

[0048] When the user applies a positive torque to the first rotating wheel 25, the lead screw 24 rotates relative to the holding plate 21, the first clamping block 231 and the first threaded section 241 move in a relative spiral motion, and the second clamping block 232 and the second threaded section 242 move in a relative spiral motion. At the same time, the first clamping block 231 slides relative to the holding plate 21 along the axial direction of the lead screw 24, and the second clamping block 232 slides relative to the holding plate 21 along the axial direction of the lead screw 24. The first clamping block 231 and the second clamping block 232 move in opposite directions, and the clamping gap decreases. If the electronic device is located in the clamping gap, the first clamping block 231 and the second clamping block 232 will gradually clamp the electronic device.

[0049] When the user applies a reverse torque to the first rotating wheel 25, the lead screw 24 rotates relative to the holding plate 21, the first clamping block 231 and the first threaded section 241 move in a relative spiral motion, and the second clamping block 232 and the second threaded section 242 move in a relative spiral motion. At the same time, the first clamping block 231 slides relative to the holding plate 21 along the axial direction of the lead screw 24, and the second clamping block 232 slides relative to the holding plate 21 along the axial direction of the lead screw 24. The first clamping block 231 and the second clamping block 232 move in opposite directions, and the clamping gap increases. If the electronic device is located in the clamping gap, the first clamping block 231 and the second clamping block 232 gradually release the electronic device.

[0050] Furthermore, the support unit 20 also includes a support boss 29 fixed to the support plate 21. The support boss 29 protrudes from the side of the support plate 21 that contacts the electronic device, thereby forming a support step between the support boss 29 and the support plate 21, which can support the electronic device.

[0051] Furthermore, the holding unit 20 also includes a locking nut 26 connected to the lead screw 24. The locking nut 26 can lock the lead screw 24 to the holding plate 21, thereby restricting the degree of freedom of rotation of the lead screw 24 relative to the holding plate 21, ensuring that the first clamping block 231 and the second clamping block 232 are relatively stationary, so that the electronic device can be reliably clamped by the first clamping block 231 and the second clamping block 232 for a long time. When it is necessary to change the clamping gap or release the electronic device, the locking nut 26 can be adjusted to release the locking of the lead screw 24, thereby restoring the degree of freedom of rotation of the lead screw 24.

[0052] Furthermore, the support unit 20 also includes a heat sink 28 and a fan 27 disposed on the support plate 21. The support plate 21 has ventilation holes, the heat sink 28 is connected to the ventilation holes, and the fan 27 can generate airflow through the ventilation holes. When the heat of the electronic device is conducted to the support plate 21, the heat sink 28 can dissipate the heat of the support plate 21 to the ventilation holes, and then this heat is carried away by the airflow generated by the fan 27. This can achieve heat dissipation and cooling of the support unit 20, ensuring that heat does not easily accumulate between the electronic device and the support unit 20.

[0053] See Figures 5-6In some embodiments, the electronic device mounting bracket further includes an angle adjustment mechanism. This mechanism adjusts the orientation of the holding unit 20 to change the screen orientation of the electronic device, allowing the user to adjust the screen to the most suitable viewing position. Specifically, the angle adjustment mechanism includes a second rotating wheel 41, a pitch rotation shaft 42, a worm gear 43, a worm 44, and an input shaft 45. The holding unit 20 also includes a connecting shaft 22, which is fixedly connected to the holding plate 21 and the pitch rotation shaft 42. The pitch rotation shaft 42 is rotatably mounted on the frame unit 10. The worm gear 43 is coaxially connected to the pitch rotation shaft 42, and the worm 44 is coaxially connected to the input shaft 45. The worm gear 43 and the worm 44 mesh with each other. The second rotating wheel 41 is connected to the input shaft 45. When the user applies torque to the second rotating wheel 41, the input shaft 45 and the worm 44 rotate, the worm wheel 43 rotates under the meshing action of the worm 44 and synchronously drives the pitch rotating shaft 42, which in turn drives the connecting shaft 22 to rotate, thereby causing the carrier plate 21 to rotate around the axis of the pitch rotating shaft 42.

[0054] Because the worm gear 43 and worm 44 have a self-locking function, when the torque applied to the second rotating wheel 41 is stopped, the worm gear 43 and worm 44 are self-locked and fixed. Therefore, the pitch rotation shaft 42 can be fixed relative to the frame unit 10, so the carrying unit 20 and the electronic equipment can be fixed relative to the frame unit 10 and the object surface.

[0055] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
