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.

[0034] 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.

[0035] like Figure 1-Figure 7As shown, the utility model provides a back plate assembly, which is used to clamp objects. Specifically, the back plate assembly in this embodiment is applied to a mobile phone holder to clamp mobile phones, tablet computers, various handheld terminals and other products. The back plate assembly 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 with two, and the two clamping arms 3 are respectively located at the two ends of the base 1, and the two clamping arms 3 cooperate with each other to clamp the object. The clamping arm 3 includes a fixedly connected clamping portion 32 and a sliding portion 31, the two clamping portions 32 are arranged opposite to each other, and the two clamping portions 32 are used to clamp the object together, and the two sliding portions 31 are both slidably connected to the base 1. By sliding the two sliding portions 31 on the base 1, the distance between the two clamping portions 32 is changed, so as to clamp objects of different specifications. The two sliding parts 31 slide on the base 1 along the connecting line direction of the two clamping parts 32. The elastic member 4 is arranged between the sliding part 31 and the base 1, and the elastic member 4 is used to make the sliding part 31 slide in the direction of the base 1, that is, the elastic member 4 is used to make the sliding part 31 slide inward on the base 1, so that the two clamping parts 32 can reliably clamp the object. An avoidance groove 15 is arranged on the base 1, and at least part of the elastic member 4 is located in the avoidance groove 15. By arranging the avoidance groove 15 on the base 1, at least part of the elastic member 4 is located in the avoidance groove 15, thereby reducing the interval that needs to be reserved between the clamping arm 3 and the base 1 or achieving the clamping arm 3 and the base 1 to fit together, and reducing the thickness of the back plate assembly.

[0036] The elastic member 4 in this embodiment is preferably a spring, and the two ends of the spring are respectively connected to the sliding part 31 and the base 1. When the operator operates the sliding part 31 to slide outward on the base 1, the spring is compressed. After the external force is removed, the sliding part 31 slides inward on the base 1 under the elastic force of the spring. The shape of the corresponding avoidance groove 15 matches the shape of the spring, and at least part of the spring along its radial direction is located in the avoidance groove 15 to reduce space occupation. In other embodiments, the elastic member 4 can also be selected as a torsion spring, the spring body of the torsion spring is installed on the base 1, and the two ends of the torsion spring are respectively connected to the base 1 and the sliding part 31. When the operator operates the sliding part 31 to slide outward on the base 1, the spring body of the torsion spring is twisted, thereby increasing the elastic potential energy. After the external force is removed, the spring body of the torsion spring recovers under the action of the elastic potential energy, and drives the sliding part 31 to slide inward on the base 1 through the two ends. The shape of the corresponding avoidance groove 15 matches the spring body of the torsion spring, and at least a portion of the spring body of the torsion spring along its axial direction is located in the avoidance groove 15 to reduce space occupation.

[0037] Furthermore, if Figure 1-Figure 3As shown, two sliding grooves 14 are respectively provided at both ends of the base 1, and the sliding part 31 is slidably matched with the sliding groove 14 and slides inward or outward along the sliding groove 14. A receiving groove 313 is provided on the sliding part 31, and the receiving groove 313 is connected with the avoidance groove 15, and the receiving groove 313 and the avoidance groove 15 together form a receiving space for the elastic member 4, and the elastic member 4 is located in the receiving space. By continuing to set the receiving groove 313 on the basis of the avoidance groove 15, while meeting the installation space requirements of the elastic member 4, the sliding part 31 is fitted with the base 1, so that the thickness of the backplane assembly is further reduced. In addition, the elastic member 4 can also be set to two, and the corresponding avoidance groove 15 and the receiving groove 313 are both set to two, the two avoidance grooves 15 are set in parallel, and the two receiving grooves 313 are set in parallel, and two receiving spaces are formed, and the two elastic members 4 are respectively set in the two receiving spaces. Compared with the case of setting only one elastic member 4, setting two elastic members 4 can also meet the use requirements and can reduce the specifications and dimensions of each elastic member 4. On this basis, the thickness of the base 1 and the sliding part 31 can be further reduced while meeting the structural strength, so as to further reduce the thickness of the backplane assembly.

[0038] Specifically, a first mounting seat 12 is fixedly provided on the base 1, and a second mounting seat 311 is fixedly provided on the sliding portion 31, and both the first mounting seat 12 and the second mounting seat 311 are located in the accommodating space. 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 respectively connected to the first mounting seat 12 and the second mounting seat 311. When the user operates the sliding portion 31 to slide outward relative to the base 1, the second mounting seat 311 on the sliding portion 31 slides toward the outside, that is, slides toward the direction close to the first mounting seat 12. The elastic member 4 is compressed in this process and its elastic potential energy increases with the increase of the sliding distance. When an object is placed between the clamping parts 32 and the external force is removed, under the elastic force of the elastic member 4, the second mounting seat 311 slides in the direction away from the first mounting seat 12, that is, the sliding part 31 slides inward relative to the base 1 under the elastic force of the elastic member 4 until the clamping part 32 contacts the object. At this time, the elastic member 4 still has a certain elastic potential energy, and under the elastic force, the clamping part 32 abuts against the object, so that the object is reliably clamped between the two clamping parts 32.

[0039] Furthermore, if Figure 1-Figure 7As 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 4 and Figure 5 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 6-Figure 7 As shown, when the outward sliding strokes of the two clamping arms 3 are both at their maximum, the distance between the two clamping arms 3 is the longest, the clamping arms 3 are at the second limit position, and the limiting member 13 contacts the other end wall of the limiting hole 312, i.e., the second limiting end 3122. The limiting hole 312 is arranged in parallel with the accommodating groove 313, i.e., the length direction of the limiting hole 312 is parallel with the sliding direction of the sliding portion 31, so as to avoid friction or jamming between the limiting member 13 and the hole wall of the limiting hole 312.

[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 slide with the two limiting holes 312 respectively, thereby strengthening the structural strength and ensuring the smoothness of the movement process.

[0041] For further information, please refer to Figure 7 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.

[0042] For further information, please refer to Figure 5 and Figure 7As shown, the clamping portion 32 and the sliding portion 31 in this embodiment are arranged vertically, and a buffer pad 321 is fixedly connected to the inner side of the clamping portion 32 for contacting with an object to prevent the clamping portion 32 from directly contacting the object and causing scratches or bruises on the surface. 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 small, 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, and further prevent the object from slipping off.

[0043] The utility model provides a mobile phone holder, comprising a connecting structure and a back plate assembly in this embodiment, wherein the connecting structure is connected to a base 1. By arranging the back plate assembly in this embodiment, the volume of the mobile phone holder is reduced, and the mobile phone holder is more compact and flexible in use.
