Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone brackets, in particular to a clamping structure and a mobile phone bracket. Background Art

[0002] The mobile phone holder can be divided into a clamping structure and functional components. The clamping structure is used to clamp the mobile phone. The functional components are connected to the clamping structure to achieve functions such as angle adjustment and lifting. The mobile phone holder is stably connected to the usage scenario by relying on the functional components, such as being connected to the air outlet of the vehicle as a vehicle-mounted mobile phone holder, or being connected to the bed as a bedside mobile phone holder.

[0003] In order to ensure the reliability of mobile phone clamping during use, the clamping structure of existing mobile phone holders generally adopts springs to achieve clamping, and the two clamping arms are connected by the two ends of the spring, and the two clamping arms are opened or retracted synchronously. However, in actual use, users often only operate one of the clamping arms. The two clamping arms are linked by the spring, and the related linkage parts are easily deformed and stuck due to the offset load, which eventually leads to partial functional failure. In addition, when the space in a certain direction in the use scenario is limited, such as near the car door or the bed frame, because the space is not enough to meet the synchronous movement of the two clamping arms at the same time, it is necessary to first adjust the position of the mobile phone holder, clamp the mobile phone and then return to its original position, which reduces the user experience.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] like Figure 1-Figure 6As shown, the utility model provides a clamping structure, which is used to clamp objects. Specifically, the clamping structure in this embodiment is applied to a mobile phone holder to clamp mobile phones, tablet computers, various handheld terminals and other products. The clamping structure includes a base 1, a cover plate 2, a clamping arm 3 and an elastic member 4. The base 1 is used to install the clamping arm 3 and the elastic member 4. After the clamping arm 3 and the elastic member 4 are installed on the base 1, the cover plate 2 is positioned and connected to the base 1 through a positioning member 11 provided on the base 1. The clamping arm 3 is provided in two, and the two clamping arms 3 are respectively installed at both ends of the base 1, and the two clamping arms 3 are arranged opposite to each other. One of the clamping arms 3 can slide relative to the base 1 to change the distance between the two clamping arms 3, and the sliding direction of the clamping arm 3 is the connecting direction of the two clamping arms 3. By changing the distance between the two clamping arms 3, objects of different specifications can be clamped. One end of the elastic member 4 is connected to the base 1, and the other end of the elastic member 4 is connected to one of the clamping arms 3, specifically, the elastic member 4 is connected to the clamping arm 3 that can slide relative to the base 1. The elastic member 4 is used to make one of the clamping arms 3 slide relative to the base 1 toward the other clamping arm 3. When clamping an object, first operate one of the clamping arms 3 to slide relative to the base 1, increase the distance between the two clamping arms 3, and place the object between the two clamping arms 3. At this time, the clamping arm 3 slides relative to the base 1 toward the other clamping arm 3 under the action of the elastic member 4, thereby clamping the object. The clamping structure in this embodiment does not involve the linkage of the moving parts. During use, the movement is not subject to eccentric load, the probability of deformation and jamming is reduced, and the structural reliability is improved. At the same time, for the use scenario where space is limited in a certain direction, the clamping can be completed by operating one of the clamping arms 3, thereby improving the applicability in a small space.

[0035] Furthermore, in this embodiment, two elastic members 4 are provided, and the two elastic members 4 are respectively installed at the two ends of the base 1. Both clamping arms 3 can slide relative to the base 1, and the two elastic members 4 are respectively connected to the two clamping arms 3, and are used to make one clamping arm 3 slide toward the other clamping arm 3. In this way, when one clamping arm 3 is deformed or partially damaged and loses its movement function, the clamping requirement can still be met by the other clamping arm 3.

[0036] Specifically, Figure 1-Figure 6 As shown, the clamping arm 3 includes a sliding portion 31 and a clamping portion 32 which are fixedly connected, and the clamping portion 32 and the sliding portion 31 are arranged vertically. The sliding portion 31 is arranged parallel to the base 1 and is slidably connected to the base 1. A sliding groove 14 is arranged on the base 1. The sliding portion 31 is placed in the sliding groove 14 and can slide along the sliding groove 14. Its sliding direction is the direction of the line connecting the two clamping arms 3. The clamping portion 32 is arranged protruding from the base 1 and is used to clamp an object. A buffer pad 321 is fixedly connected to the inner side of the clamping portion 32 to prevent the clamping portion 32 from directly contacting the object and causing scratches or scratches on the surface.

[0037] For details, please refer to Figure 2 As shown, the thickness of the buffer pad 321 increases in the direction away from the sliding portion 31. After clamping the object, the object contacts the end of the buffer pad 321 close to the sliding portion 31, where the thickness of the buffer pad 321 is smaller, so that the end of the buffer pad 321 away from the sliding portion 31 has a certain blocking effect on the object, thereby effectively preventing the object from slipping off. At the same time, the side of the buffer pad 321 away from the clamping portion 32, that is, the side of the buffer pad 321 in contact with the object, is set to a serrated structure to further increase the friction between the buffer pad 321 and the object, further preventing the object from slipping off.

[0038] Optionally, please continue to refer to Figure 2 As shown, a downwardly protruding protrusion 314 is formed at one end of the sliding portion 31 near the clamping portion 32. When no external force is applied, the distance between the two clamping arms 3 is the shortest. When an object needs to be clamped, one of the clamping arms 3 is operated to slide in a direction away from the other clamping arm 3, that is, the clamping arm 3 is operated to slide outward. This process requires overcoming the elastic force of the elastic member 4. If the clamping arm 3 is operated to slide outward by pulling the clamping portion 32, the portion where the clamping portion 32 and the sliding portion 31 are connected is subjected to shear force and is easily deformed or even damaged during the sliding process. Therefore, the downwardly protruding protrusion 314 is provided, and the clamping arm 3 is slid outward by pulling the downwardly protruding protrusion 314. During this process, the portion where the clamping portion 32 and the sliding portion 31 are connected only bears the pulling force along its length direction, thereby effectively preventing the portion where the two are connected from being deformed or damaged.

[0039] Furthermore, if Figure 1-Figure 6 As shown, in order to prevent the clamping arm 3 from sliding too long relative to the clamping portion 32 and causing it to fall out of the sliding groove 14, a limit member 13 is fixedly provided on the base 1, and a limit hole 312 is correspondingly provided on the sliding portion 31, and the limit member 13 and the limit hole 312 are slidably matched. The limit hole 312 is set as an oblong hole, and the limit member 13 is set as a columnar structure and the diameter of the limit member 13 is equal to the end diameter of the oblong hole, so that the center distance at the two ends of the oblong hole is the sliding stroke of the clamping arm 3. Correspondingly, the clamping arm 3 has a first limit position and a second limit position. Please refer to Figure 3 and Figure 4 As shown, when the clamping arms 3 are not subjected to external force, the distance between the two clamping arms 3 is the shortest, the clamping arms 3 are located at the first limit position, and the limiting member 13 contacts one end wall of the limiting hole 312, namely the first limiting end 3121. Figure 5-Figure 6 As shown, when the outward sliding stroke of the two clamping arms 3 reaches the maximum, the distance between the two clamping arms 3 is the longest, the clamping arms 3 are located at the second extreme position, and the limiting member 13 contacts the other end wall of the limiting hole 312, namely the second limiting end 3122.

[0040] Optionally, in order to strengthen the structural strength of the connection between the base 1 and the sliding part 31, two parallel limiting holes 312 are set on each sliding part 31, and two corresponding limiting members 13 are set on the base 1 to cooperate with the two limiting holes 312 respectively, so as to strengthen the structural strength and ensure the smoothness of the movement process.

[0041] Furthermore, if Figure 1-Figure 6 As shown, in order to realize the installation of the elastic member 4, a first mounting seat 12 is fixedly arranged on the base 1, and a second mounting seat 311 is arranged on the clamping arm 3. The first mounting seat 12 and the second mounting seat 311 are arranged opposite to each other and the first mounting seat 12 is located outside the second mounting seat 311. The two ends of the elastic member 4 are connected to the first mounting seat 12 and the second mounting seat 311 respectively. When one of the clamping arms 3 slides in a direction away from the other clamping arm 3, that is, when one of the clamping arms 3 slides outward, the second mounting seat 311 slides outward synchronously, that is, the second mounting seat 311 moves toward the first mounting seat 12, and the elastic member 4 is compressed in this process and its elastic potential energy increases with the increase of the sliding distance. In this embodiment, the elastic member 4 is preferably a coil spring, and its two ends are fixedly sleeved on the first mounting seat 12 and the second mounting seat 311 respectively. In other embodiments, the elastic member 4 can also be set as a torsion spring, and its spring body and one of its ends are fixedly mounted on the base 1, and the two ends are respectively mounted on the first mounting seat 12 and the second mounting seat 311, which can also achieve the same function as the coil spring.

[0042] Alternatively, if Figure 4-Figure 6 As shown, in order to reduce the volume of the clamping structure and reduce the space occupied so as to be suitable for clamping objects with greater thickness, a receiving groove 313 is also provided on the sliding part 31. The first mounting seat 12, the second mounting seat 311 and the elastic member 4 are all located in the receiving groove 313, so that the gap between the sliding part 31 and the base 1 is smaller, and the overall thickness is smaller. In addition, an avoidance groove 15 can be provided at a position corresponding to the receiving groove 313 on the base 1 at the same time, and the receiving space of the elastic member 4 is formed by the avoidance groove 15 and the receiving groove 313, so that the sliding part 31 and the base 1 can be fitted together, further reducing the overall thickness.

[0043] The utility model provides a mobile phone holder, comprising a connection structure and a clamping structure in this embodiment, wherein the connection structure is connected to a base 1. By providing the clamping structure in this embodiment, the reliability of the mobile phone holder and the applicability of the mobile phone holder in a small space are improved, thereby improving the user experience.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
