[0026] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] The embodiment of the present application is a telescopic storage bracket, and its specific structure is as follows Figure 1-8 The storage stand can be used as a smartphone stand, tablet stand, etc.

[0030] like Figure 1 As shown in the figure, the storage rack of the embodiment includes a base 10, a fixed head 20, and an axially retractable telescopic component 30. One end of the telescopic component 30 penetrates the receiving hole 11 of the base 10 to form a sliding connection, and the other end of the telescopic component 30 is connected to the fixed head 20. When the storage rack is in the extended state, the telescopic component 30 is in the extended state and extends out of the receiving hole 11 of the base 10. Figure 1 As shown, when the storage stand is in the retracted state, the telescopic assembly 30 is also retracted and retracted into the receiving hole 11 of the base 10. Thus, the storage stand of the embodiment connects the base 10 and the fixed head 20 via the telescopic assembly 30. When needed, the telescopic assembly 30 can be extended to separate the base 10 and the fixed head 20, allowing the fixed head 20 to be used to hold electronic devices. When not in use, the storage stand can be retracted to reduce its overall size, thereby improving portability and transportation.

[0031] In some embodiments, as Figure 1 As shown, the fixing head 20 has a built-in magnetic ring 21 to secure external electronic devices, such as mobile phones and tablets, through magnetic attraction. In other embodiments, the fixing head can be provided with a suction cup on its surface to secure the electronic device through vacuum suction, or a right-angled surface can be provided on the fixing head to directly support the electronic device. Of course, the fixing head can also be made into a common clamping frame to secure the electronic device through clamping force.

[0032] In some embodiments, as Figure 1 As shown, a suction cup is fixed at the bottom of the base 10, which generates a vacuum force to fix the entire storage bracket to the flat / curved surface. In other embodiments, an adhesive layer can also be provided at the bottom of the base to fix the entire storage bracket to the flat / curved surface by gluing.

[0033] In some embodiments, as Figure 1As shown, a ring groove 22 is provided on the bottom surface of the fixing head 20, and a top cover 13 is fixed on the top of the base 10 by snapping. The top cover 13 is provided with a ring protrusion 131, and the receiving hole 11 is the middle hole of the top cover 13. Figure 2 As shown, the annular protrusion 131 is placed in the annular groove 22 to reduce the occupied space, and at the same time, the bottom surface of the fixing head 20 and the horizontal bar 132 of the top cover 13 abut against each other.

[0034] In some embodiments, as Figure 1 As shown, the telescopic assembly 30 includes a telescopic cylinder 50 and a connector 40. The telescopic cylinder 50 penetrates the receiving hole 11 of the base 10 and forms a sliding connection with the receiving hole 11. One end of the connector 40 is connected to the fixed head 20 through a universal ball structure 61, and the other end of the connector 40 penetrates the telescopic cylinder 50 and forms a sliding connection with the telescopic cylinder 50. The sliding direction of the connector 40 and the sliding direction of the telescopic cylinder 50 are both axial to the telescopic cylinder 50. Figure 1 and Figure 3 As shown, when the storage bracket is in the extended state, a section of the connector 40 connected to the fixed head 20 extends out of the telescopic cylinder 50 and the connector 40 and the telescopic cylinder 50 form a snap connection, and a section of the telescopic cylinder 50 extends out of the receiving hole 11 of the base 10 and the telescopic cylinder 50 and the receiving hole 11 of the base 10 form a snap connection. Figure 3 In the state shown, the fixing head 20 is rotated relative to the connecting member 40 to a suitable angle, and the following is obtained: Figure 5 Shown state. Combined Figure 2 and Figure 4 As shown, when the storage bracket is in the retracted state, the connecting member 40 is retracted into the telescopic cylinder 50 and the telescopic cylinder 50 is retracted into the receiving hole 11 of the base 10. At the same time, the fixing head 20 is in contact with the base 10. The retracted telescopic cylinder 50 and the connecting member 40 cannot be directly observed from the outside of the storage bracket, and the integrity of the storage bracket is improved.

[0035] like Figure 1 As shown, the connector 40 and the fixed head 20 are rotatably connected via a universal ball joint 61. When the fixed head 20 is away from the base 10, the range of motion of the fixed head 20 is expanded, and the fixed head 20 can rotate to a suitable position around the universal ball joint 61. In other embodiments, the connector and the fixed head can also be connected using other conventional multi-axis structures.

[0036] In some embodiments, as Figure 1 As shown, a positioning column 14 is provided in the middle of the receiving hole 11 of the base 10, and a positioning hole 41 is provided in the middle of the connecting member 40, and the opening of the positioning hole 41 faces the positioning column 14. Figure 2As shown, the positioning post 14 is inserted into the positioning hole 41 so that the connecting member 40 remains coaxial with the telescopic cylinder 50 when moving up and down axially relative to the telescopic cylinder 50, thereby improving the stability of the telescopic movement.

[0037] In some embodiments, as Figure 6 As shown, the outer wall of the telescopic tube 50 is provided with a radially outwardly projecting annular plate 51, and a receiving groove 111 corresponding to the annular plate is formed at the opening of the receiving hole 11. When the storage rack is extended, the telescopic tube 50 slides until the annular plate 51 is seated within the receiving groove 111. This limits the maximum outward travel of the telescopic tube 50 relative to the receiving hole 11, preventing the telescopic tube 50 from separating from the base 10 when extended.

[0038] In some embodiments, combined Figure 6 and Figure 7 As shown, the annular plate 51 is provided with at least one positioning groove 52. Specifically, there are four positioning grooves 52, which divide the annular plate 51 into four equal parts. Figure 6 As shown, an axial strip-shaped positioning protrusion 112 is provided on the inner wall of the accommodating hole 11 , and the strip-shaped positioning protrusion 112 passes through the positioning groove 52 , thereby guiding the axial sliding of the telescopic cylinder 50 and improving the stability of the telescopic activity.

[0039] In some embodiments, as Figure 6 As shown, an axially extending enclosure 113 is provided at the opening of the receiving hole 11, and an accommodating groove 111 is formed between the enclosure 113 and the inner wall of the receiving hole 11. Figure 6 and Figure 7 As shown, the inner wall of the enclosure 113 is provided with a first latch 114, and the outer wall of the telescopic cylinder 50 is correspondingly provided with a first latching groove 531 and a second latching groove 532, which are arranged axially. When the storage bracket is extended, the first latch 114 is seated in the first latching groove 531, forming a locking engagement, thereby preventing the telescopic cylinder 50 from loosening relative to the receiving hole 11 in the absence of external forces. When the storage bracket is retracted, the first latch 114 is seated in the second latching groove 532, thereby preventing the telescopic cylinder 50 from loosening relative to the receiving hole 11 in the absence of external forces.

[0040] In some embodiments, as Figure 6 As shown, the inner wall of the telescopic cylinder 50 is provided with a third slot 533 and a fourth slot 534 axially distributed at positions corresponding to the first slot 531 and the second slot 532. Specifically, the position of the third slot 533 corresponds to the position of the first slot 531, and the position of the fourth slot 534 corresponds to the position of the second slot 532. Figure 6 and Figure 7As shown, the outer wall of the connector 40 is provided with a plurality of second clamping heads 42. When the storage rack is in the retracted state, the connector 40 is located within the telescopic cylinder 50, and the second clamping heads 42 are seated in the third clamping slots 533, forming a locking engagement. This prevents the connector 40 from loosening relative to the telescopic cylinder 50 in the absence of external force. When the storage rack is in the extended state, the second clamping heads 42 are seated in the fourth clamping slots 534.

[0041] In some embodiments, as Figure 6 As shown, a cavity 535 is provided inside the wall where the first slot 531 , the second slot 532 , the third slot 533 and the fourth slot 534 are located, which can improve the elasticity of the wall at that location, make it easier to deform, and reduce the resistance during expansion and contraction.

[0042] In some embodiments, combined Figure 6 and Figure 7 As shown, the side wall of the connecting member 40 is provided with two radial protrusions 43, and the inner wall of the telescopic cylinder 50 is provided with axial limiting grooves 54 corresponding to the radial protrusions 43. The radial protrusions 43 are placed in the limiting grooves 54 and form a sliding connection. The limiting grooves 54 are used to limit the maximum extension of the connecting member 40 relative to the telescopic cylinder 50 to prevent the connecting member 40 from detaching from the telescopic cylinder 50.

[0043] In some embodiments, as Figure 7 As shown, the connecting member 40 is provided with at least one radial spring tooth 44, the outer end of the spring tooth 44 protrudes from the side wall of the connecting member 40, and the inner wall of the telescopic cylinder 50 is provided with a limiting step 55. Figure 1 and Figure 7 As shown, when the storage bracket is in the extended state, the spring teeth 44 are engaged with the limiting step 55, and the radial protrusion 43 is also at the end of the limiting groove 54. When the connecting member 40 is subjected to axial thrust, it cannot move relative to the telescopic cylinder 50.

[0044] In some embodiments, combined Figure 1 and Figure 7 As shown, the middle position of the outer end of the spring tooth 44 is provided with an inclined surface 441 that is inclined downward toward the inner wall of the telescopic cylinder 50, and the receiving hole 11 is provided with a vertical column 15, which corresponds to the spring tooth 44 one by one. The vertical column 15 penetrates the telescopic cylinder 50, and the position of the vertical column 15 corresponds to the outer end of the spring tooth 44. When the storage bracket is in the extended state, as shown in FIG. Figure 1 As shown, when the connecting member 40 is subjected to axial thrust, the connecting member 40 and the telescopic cylinder 50 are synchronously retracted downward into the accommodating hole 11. When the telescopic cylinder 50 is blocked and stops axial movement (i.e., reaches the end of the stroke), the top inclined surface 151 of the vertical column 15 is squeezed with the inclined surface 441 to compress the outer end of the spring tooth 55 into the connecting member 40. At this time, the connecting member 40 will not be blocked by the limiting step 55, and the connecting member 40 can be smoothly retracted into the telescopic cylinder 50, finally completing the contraction of the storage bracket, and obtaining the result as shown in FIG. Figure 2 As shown in the status. Figure 1 As shown, there are two spring teeth 44 , so there are two corresponding vertical columns 15 , and there are also two corresponding limiting steps 55 .

[0045] In some embodiments, as Figure 8 As shown, the bottom of the connector 40 is fixed with a bottom cover 49 by screws. After removing the bottom cover 49, the internal structure of the connector 40 can be seen. The connector 40 is provided with two spring teeth 44, and the two spring teeth 44 form a central symmetry. Figure 8 As shown, two spring teeth 44 are positioned between two side plates 45, and their movement is restricted by the side plates 45. A spring 46 is sandwiched between the inner end of the spring tooth 44 and the trapezoidal groove 48 in the middle, providing a restoring force for the spring tooth 44. The extension arm of the spring tooth 44 is provided with a strip-shaped limiting hole 442. A limiting boss 47 is provided within the connector 40. The limiting boss 47 is inserted into the strip-shaped limiting hole 442 to limit the maximum travel of the spring tooth 44.
