Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mobile phone brackets and relates to a mobile phone bracket with a rack cam with damping for quick tightening and loosening. Background Art
[0002] There are many types of mobile phone holders. In life, mobile phone holders that are commonly installed and fixed on motorcycles, electric vehicles or bicycles are widely used. The fixed mobile phone holder clamps the mobile phone, which has the advantages of freeing hands and using the mobile phone's navigation to assist riding. However, it is found that the current mobile phone holders still have the following shortcomings:
[0003] 1. Traditional mobile phone holders use springs to push inward on one or both sides to clamp the phone. The springs will become weaker than the original state after multiple clamping, resulting in a decrease in the clamping strength on both sides of the mobile phone holder. When riding on bumpy roads, the phone may fall out and break.
[0004] 2. The traditional mobile phone holder has a weak shock absorption method. For example, only the spring set inside is used to form a local shock absorption effect, and the shock absorption performance is weak, which affects the use of the mobile phone;
[0005] 3. The existing mobile phone holder only functions as a mobile phone holder to be installed on a bicycle or electric motorcycle. The single clamping function cannot adapt to the riding needs of different application scenarios. For example, the mobile phone interface will reflect light when riding during the day, which may make it difficult to see the navigation route on the mobile phone interface. Utility Model Content

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0045] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0046] To solve the above purpose, the utility model embodiment provides a rack 10 cam with damping to quickly tighten the mobile phone holder, refer to Figure 1-4 As shown, the mobile phone holder includes:
[0047] A fixed clamping seat 1 with a cavity 6 on one side, a shock absorbing mechanism 5 connected to the outer side of the back side of the fixed clamping seat 1, and a mounting hole 7 is provided on the back side of the fixed clamping seat 1;
[0048] A sliding clamping seat 2 is arranged corresponding to the fixed clamping seat 1, and one side of the sliding clamping seat 2 is provided with two one-piece cylinder arms 8 which are slidably matched with the cavity 6 to form a slot 9 penetrating the sliding clamping seat 2, and the inner side wall of the slot 9 is provided with an integrally connected rack 10, and a spring 11 for pushing the cavity 6 is arranged inside the one-piece cylinder arm 8;
[0049] A damping mechanism 4 disposed in the fixed clamping seat 1 and meshingly connected with the rack 10 to enable the sliding clamping seat 2 to slide in a balanced manner relative to the fixed clamping seat 1;
[0050] The helical gear loosening mechanism 3 installed in the slot hole 9 and the mounting hole 7 is used to enable the fixed clamping seat 1 and the sliding clamping seat 2 to achieve a quick clamping state or a quick loosening state.
[0051] In this embodiment, under the action of the spring 11, the sliding clamping seat 2 will pop outward relative to the fixed clamping seat 1. Because the damping mechanism 4 is engaged and connected with the rack 10, the sliding speed of the sliding clamping seat 2 is relatively slow, which effectively prevents the sliding clamping seat 2 from violently popping out and improves the comfort of use.
[0052] For further reference, Figure 2 , Figure 3 and Figure 6 As shown, the helical gear tensioning mechanism 3 includes a pull plate 12, an eccentric cam handle 13, a handle latch 14, a rotating hook block 15, a hook inclined spring 16, a hook latch 17, and a hook seat 18. The pull plate 12 is movable through the slot 9. The outer end of the pull plate 12 is provided with an eccentric cam handle 13 through the handle latch 14. The eccentric cam handle 13 is located on the outer side of the sliding clamping seat 2. The rotating hook block 15 is laterally provided with a waist-shaped hole 19. The hook latch 17 is installed through the waist-shaped hole 19. In the cavity 6, an oblique blind hole 20 is provided on the rotating hook block 15, and a hook oblique spring 16 is installed in the oblique blind hole 20. The mounting hole 7 is provided with a hook seat 18. The two ends of the hook oblique spring 16 act on the hook seat 18 and the rotating hook block 15 respectively to push the front end of the rotating hook block 15 toward the side of the pull plate 12. The surface of the pull plate 12 is provided with a first oblique tooth 21, and the front end surface of the rotating hook block 15 is provided with a second oblique tooth 22. The first oblique tooth 21 and the second oblique tooth 22 are meshed and connected with each other.
[0053] With this arrangement, the eccentric cam handle 13 will increase the outward pulling force on the pull plate 12 during the downward bending process, and the first bevel teeth 21 and the second bevel teeth 22 will engage with each other to drive the rotating hook block 15 to move toward the sliding clamping seat 2. The rotating hook block 15 is obliquely pressed by the hook bevel spring 16, and the first bevel teeth 21 of the rotating hook block 15 are always hooked on the second bevel teeth 22 of the pull plate 12. In this way, the clamping of the mobile phone between the fixed clamping seat 1 and the sliding clamping seat 2 will be more reliable and powerful, and the bumpy road section will not cause the mobile phone to fall out.
[0054] For further reference, Figure 3 As shown, the rotating hook block 15 is provided with a finger pressing end portion 23 on a side away from the second beveled tooth 22, which is used to drive the rotating hook block 15 to rotate along the hook latch 17, so that the second beveled tooth 22 is separated from the first beveled tooth 21. In this way, by pressing the finger pressing end portion 23, the rotating hook block 15 is rotated, the first beveled tooth 21 is separated relative to the second beveled tooth 22, and the sliding clamping seat 2 is quickly moved away relative to the fixed clamping seat 1 under the action of the spring 11. After the mobile phone is placed and clamped, the eccentric cam handle 13 is moved in place to tighten the rotating hook block 15 and quickly lock it.
[0055] For further reference, Figure 6 As shown, the pull plate 12 is provided with a limiting rib 24 on one side away from the handle latch 14, and the limiting rib 24 is oriented in the same direction as the first oblique tooth 21. In this way, the limiting rib 24 can always maintain the relative position of the pull plate 12 and the rotating hook block 15, preventing the pull plate 12 from falling out and causing the sliding clamping seat 2 to separate from the fixed clamping seat 1.
[0056] Quick release for the first use: move the eccentric cam handle 13 downward to the released state, and then press the finger pressing end 23 of the rotating hook block 15. At this time, the sliding clamping seat 2 will automatically slide outward a certain distance under the tension of the hook bevel spring 16, for example, a sliding distance of 30 mm. This distance is limited by the activity space between the limiting rib 24 at the end of the pull rod of the rack 10 and the first bevel tooth 21 of the rotating hook block 15, and the damping effect of the damping mechanism 4 makes the sliding movement of the sliding clamping seat 2 smooth and smooth.
[0057] Quick locking for the first use: put the mobile phone in, then press the eccentric cam handle 13 with your hand to make the pull plate 12 slide inward quickly, so that the fixed clamping seat 1 and the sliding clamping seat 2 are in contact with the mobile phone and pressed without moving, then release your hand. At this time, the sliding clamping seat 2 will be loosened outward by a certain distance, for example 4 mm, under the tension of the hook spring 11 and the limit of the waist-shaped hole 19 of the rotating hook block 15, and then pull the eccentric cam handle 13 upward to the locked state, at this time The sliding clamping seat 2 will slide inward and then lock the mobile phone.
[0058] Normal quick release and lock: For the first use, follow the above two steps to adjust the distance between the sliding clamping seat 2 and the fixed clamping seat 1. For future use, if you do not change the mobile phone, you only need to loosen the eccentric cam handle 13 downward or lock it upward to quickly loosen or lock the sliding clamping seat 2, so as to quickly take and put the mobile phone. If you want to change the mobile phone, please repeat the above two steps.
[0059] For further reference, Figure 4 and Figure 5As shown, the damping mechanism 4 includes a mounting plate 25, a damping inner gear 26, a damping rubber ring, an adjusting screw 27, and an outer damping gear 28 with inner teeth. The mounting plate 25 is fixedly mounted in the cavity 6. The lower end of the mounting plate 25 is connected with an outer damping gear 28 with inner teeth. The inner damping gear 28 with inner teeth is meshed with an inner damping gear 26. The inner damping gear 26 is connected to the mounting plate 25 through an adjusting screw 27. A damping rubber ring is provided between the outer damping gear 28 with inner teeth and the inner damping gear 26. The outer damping gear 28 with inner teeth is meshed with the rack 10. For example, the adjusting screw 27 is preferably such that the damping inner gear 26 can rotate slowly, and damping oil is added between the damping inner gear 26 and the outer damping gear 28 with inner teeth for lubrication to avoid rotation jamming, so that the sliding clamping seat 2 will not feel frustrated during the sliding process.
[0060] For further reference, Figure 4 As shown, a first clamping arm 29 is integrally connected to the outer side of the fixed clamping seat 1, a first anti-slip pad 30 is bonded to the inner side of the first clamping arm 29, and a second clamping arm 31 is integrally connected to the outer side of the sliding clamping seat 2, a second anti-slip pad 32 is bonded to the inner side of the second clamping arm 31.
[0061] For further reference, Figure 3 and Figure 7 As shown, the shock absorbing mechanism 5 includes a shock absorbing expansion plate 33, a fastening screw 34, and a silicone shock absorbing tube 35. A fixing column 36 with an internal thread is provided on the back of the fixed clamping seat 1. The shock absorbing expansion plate 33 is connected to the fixing column 36 by the fastening screw 34. A retractable silicone shock absorbing tube 35 is inserted into the fixing column 36, and both ends of the silicone shock absorbing tube 35 are tightly pressed between the fixed clamping seat 1 and the shock absorbing expansion plate 33. The silicone shock absorbing tube 35 is provided with a shock absorbing shrinking annular portion 37. The middle part of the shock absorbing expansion plate 33 is integrally connected outward with a hollow hemispherical body 38 with an open end, and a universal hemispherical expansion piece 39 with a screw head at the end is installed in the hollow hemispherical body 38. For example, for the sake of balance, four fixing columns 36 are preferably provided, and a silicone shock-absorbing tube 35 is inserted into each fixing column 36. Since the silicone shock-absorbing tube 35 is provided with a shock-absorbing shrinking ring portion 37, the elasticity of the silicone shock-absorbing tube 35 is not utilized, and the shock-absorbing shrinking ring portion 37 is utilized. Even if the mobile phone holder is clamped on a bumpy road section, the fixed clamping seat 1 can always maintain a good anti-shake and shock-absorbing effect for the shock-absorbing mechanism 5.
[0062] For further reference, Figure 8-Figure 10 As shown, the universal hemispherical expansion piece 39 is detachably connected with a clamp fastener 40 or a long arm fastener 41.
[0063] For example, in one embodiment, the clamp fastener 40 can be a clamp tightening method on one side and a nut on the other side, and the nut is screwed and fastened with the universal hemispherical extension 39 with a screw head, so that the mobile phone holder can be installed on the tube of the handle of a bicycle or an electric vehicle; in another embodiment, Fig.11 and Fig.12 As shown, the long arm fastener 41 can be a connecting arm with a long strip on one side, and an assembly plate is provided at one end of the connecting arm, which is screwed to the electric vehicle frame by means of screws, while the other side is provided with the same nut, which is screwed and fastened to the universal hemispherical extension piece 39 with a screw head. In this way, the mobile phone holder can also be installed and used in different ways, which broadens the usage.
[0064] In yet another embodiment, reference Fig.13 and Fig.14 As shown, a sunshade 42 is connected to the top of the fixed clamping seat 1, a mounting threaded hole 43 is provided on the outer side of the bottom of the fixed clamping seat 1, and a positioning assembly column 44 is provided on one side of the mounting threaded hole 43. The sunshade 42 is detachably connected to the fixed clamping seat 1 through the mounting threaded hole 43 and the positioning assembly column 44. In this way, the sunshade 42 is located above the clamped mobile phone, and can block the reflection of sunlight on the mobile phone screen during riding, so as to better maintain the viewing and use of the mobile phone; on rainy days, the sunshade 42 can also serve as a rain shield.
