[0044] See also Figure 1 and Figure 2 The embodiment of the present application provides a detachable bracket 100, including a tray assembly 10, a connecting rod assembly 20 and a base assembly 30, wherein the tray assembly 10 and the base assembly 30 are respectively arranged at two ends of the connecting rod assembly 20, and the tray assembly 10 and the base assembly 30 are connected to the connecting rod assembly 20 by threaded connection.

[0045] The detachable bracket 100 provided in the embodiment of the present application includes a tray assembly 10, a connecting rod assembly 20 and a base assembly 30, wherein the base assembly 30 serves to stabilize the center of gravity of the detachable bracket 100, the connecting rod assembly 20 is used to support the tray assembly 10, and the tray assembly 10 serves to support and hold items to be stored (such as VR / AR products). Since the tray assembly 10 and the base assembly 30 are connected to the connecting rod assembly 20 by threaded connection, consumers can assemble the components into a complete machine by themselves; conversely, when consumers do not need to use this detachable bracket 100, the complete machine can be disassembled into components to reduce storage space.

[0046] It can be understood that, compared with packaging and selling the detachable bracket 100 as a complete unit after installation, disassembling the detachable bracket 100 into parts for packaging and selling can reduce the volume of the packaging and simplify the packaging form, thereby reducing the packaging cost and transportation cost of the detachable bracket 100.

[0047] See also Figure 3 The tray assembly 10 includes a tray 11 and a threaded column 12, one end of the threaded column 12 is connected to the tray 11, the outer surface of the threaded column 12 is provided with a first external thread, and the connecting rod assembly 20 is provided with a first recessed portion 201 at one end facing the tray assembly 10, the inner surface of the first recessed portion 201 is provided with a first internal thread, and at least a portion of the threaded column 12 enters the first recessed portion 201 and is threadedly connected to the first recessed portion 201.

[0048] Exemplarily, the tray 11 and the threaded column 12 are both made of metal.

[0049] See also Figure 4 , Figure 5 and Figure 6 The connecting rod assembly 20 includes a connecting rod 21, a screw sleeve 22 and a connecting piece 23, wherein the screw sleeve 22 and the connecting rod 21 are arranged in sequence in the direction from the tray assembly 10 to the base assembly 30, the screw sleeve 22 is provided with a first hollow structure 221, the first hollow structure 221 includes the first recessed portion 201, the connecting rod 21 is provided with a second recessed portion 212 corresponding to the first hollow structure 221 and interpenetrating with each other, the connecting piece 23 passes through the first hollow structure 221 and one end of the connecting piece 23 is arranged in the second recessed portion 212, the connecting piece 23 is connected to the connecting rod 21, and a gap is maintained between the connecting piece 23 and the first recessed portion 201;

[0050] A third recessed portion 123 is formed on one end of the threaded column 12 facing the connecting rod assembly 20 , and one end of the connecting member 23 away from the connecting rod 21 is engaged with the third recessed portion 123 .

[0051] See also Figure 6 , illustratively, the first recessed portion 201 is a through hole.

[0052] See also Figure 3 , illustratively, the third recessed portion 123 is a groove.

[0053] See also Figure 6 , illustratively, the second recessed portion 212 is a groove.

[0054] It can be understood that in the embodiment of the present application, the pallet assembly 10 and the connecting rod assembly 20 are mainly connected through the threaded connection between the threaded column 12 and the screw sleeve 22. However, since the side walls of the threaded column 12 and the screw sleeve 22 are relatively thin, that is, the mechanical strength is relatively poor, the present application provides a connecting piece 23 in the connecting rod assembly 20, so that the connecting piece 23 is arranged on the inner side of the threaded column 12 and the screw sleeve 22. Since the connecting piece 23 is a solid columnar body with high mechanical strength, the mechanical strength of the connection position between the pallet assembly 10 and the connecting rod assembly 20 can be improved by providing the connecting piece 23. In addition, since the connecting piece 23 is snap-fitted to the threaded column 12, the connection stability and connection strength between the pallet assembly 10 and the connecting rod assembly 20 can also be improved.

[0055] See also Figure 1 , Figure 2 and Figure 3 The surface of the tray 11 that is away from the base assembly 30 is arc-shaped and protrudes in a direction away from the base assembly 30 .

[0056] It can be understood that by setting the upper surface of the tray 11 as an arc surface and protruding in the direction away from the base assembly 30, it can be convenient for the VR / AR product to be hung on the tray 11. It is known that VR / AR products usually have an arc-shaped structure, so that the VR / AR product can be stably attached to the tray 11, thereby achieving stability in supporting the VR / AR product.

[0057] See also Figure 3 An annular boss 13 is provided on the tray 11 on one side facing the connecting rod assembly 20 . The annular boss 13 is arranged on the outer periphery of the threaded column 12 and is spaced apart from the threaded column 12 .

[0058] It should be noted that, by providing an annular boss 13 on the tray 11 on the side facing the connecting rod assembly 20, and making the annular boss 13 provided on the outer periphery of the threaded column 12 and maintaining a gap between the threaded column 12, after the tray assembly 10 and the connecting rod assembly 20 are installed, a partial area of ​​the screw sleeve 22 can be located in the gap area between the annular boss 13 and the threaded column 12, so that the annular boss 13 can be used to cover the connection position between the screw sleeve 22 and the threaded column 12 to improve the appearance of the detachable bracket 100.

[0059] See also Figure 4For example, the outer surface of the screw sleeve 22 is an uneven rough surface, so that when the user installs the tray assembly 10 and the connecting rod assembly 20, the friction between the hand and the outer surface of the screw sleeve 22 can be increased, thereby making the installation process smoother.

[0060] Exemplarily, the outer surface of the screw sleeve 22 is provided with a plurality of strip-shaped protrusions and a plurality of strip-shaped recesses which are alternately arranged at intervals.

[0061] Exemplarily, the connecting rod 21 , the threaded sleeve 22 and the connecting member 23 are all made of metal.

[0062] See also Figure 6 The connecting member 23 includes a first connecting portion 231, which is engaged with the third recessed portion 123. The cross-section of the first connecting portion 231 is non-circular, and the cross-sectional area of ​​the first connecting portion 231 gradually decreases in the direction from the connecting rod 21 to the tray 11. The size of the third recessed portion 123 matches the size of the first connecting portion 231.

[0063] Exemplarily, the cross section of the first connection portion 231 is D-shaped, and the cross section of the third recessed portion 123 is D-shaped.

[0064] It can be understood that, in the embodiment of the present application, the cross section of the first connecting portion 231 is set to be non-circular, the cross-sectional area of ​​the first connecting portion 231 gradually decreases in the direction from the connecting rod 21 to the tray 11, and the size of the third recessed portion 123 is set to match the size of the first connecting portion 231. It can be seen that after the first connecting portion 231 is connected to the third recessed portion 123, the first connecting portion 231 cannot rotate relative to the third recessed portion 123. When the user installs the tray assembly 10 and the connecting rod assembly 20, by screwing the screw sleeve 22, the threaded column 12 and the screw sleeve 22 rotate relative to each other, so that the threaded column 12 gradually moves in the direction of deepening into the first recessed portion 201 until the threaded connection between the threaded column 12 and the screw sleeve 22 is completed. In the process of screwing the screw sleeve 22, the first connecting portion 231 and the threaded column 12 maintain a fixed connection relationship. Therefore, the user can accurately judge when the threaded connection between the threaded column 12 and the screw sleeve 22 is completed during the screwing process, so as to avoid the relative rotation between the first connecting portion 231 and the third recessed portion 123 interfering with the user's judgment, thereby improving the user's installation experience.

[0065] See also Figure 6One end of the connecting member 23 that enters the second recessed portion 212 is connected to the inner surface of the second recessed portion 212 through an adhesive, and the adhesive is located between the outer surface of the connecting member 23 and the inner surface of the second recessed portion 212.

[0066] See also Figure 6 The first hollow structure 221 includes a first recessed portion 201, a second through hole 202 and a third through hole 203 which are arranged in sequence and interconnected in the direction from the tray assembly 10 to the base assembly 30, and the cross-sectional areas of the first recessed portion 201, the second through hole 202, the third through hole 203 and the second recessed portion 212 decrease in sequence.

[0067] See also Figure 6 The connecting member 23 includes a first connecting portion 231, a second connecting portion 232, a third connecting portion 233, and a fourth connecting portion 234 which are sequentially connected in the direction from the tray assembly 10 to the base assembly 30, the first connecting portion 231 is snap-connected with the third recessed portion 123, at least a portion of the first connecting portion 231 is located in the first recessed portion 201, and a gap is maintained between the first connecting portion 231 and the inner surface of the first recessed portion 201, at least a portion of the second connecting portion 232 is located in the second through hole 202 and the size of the second through hole 202 matches, the third connecting portion 233 is located in the third through hole 203 and the size of the third through hole 203 matches, and the fourth connecting portion 234 is located in the second recessed portion 212 and the size of the fourth connecting portion 234 matches.

[0068] It can be understood that the spacing space between the first connecting portion 231 and the inner surface of the first recessed portion 201 is used to accommodate the threaded column 12 .

[0069] See also Figure 6 It can be seen that the cross-sectional areas of the second connection portion 232 , the third connection portion 233 and the fourth connection portion 234 gradually decrease.

[0070] It should be noted that, by setting the cross-sectional areas of the second through hole 202, the third through hole 203 and the second recessed portion 212 to decrease successively, the connection position of the second through hole 202 and the third through hole 203 in the screw sleeve 22 forms a first hanging platform, and the intersection position of the screw sleeve 22 and the connecting rod 21 forms a second hanging platform, so that when the connecting member 23 is installed, the second connecting portion 232 and the third connecting portion 233 of the connecting member 23 are hung on the first hanging platform and the second hanging platform respectively, and by suspending the connecting member 23, a gap can be maintained between the bottom of the connecting member 23 (that is, the bottom of the fourth connecting portion 234) and the bottom of the second recessed portion 212, so that when an adhesive (glue) is used to connect the fourth connecting portion 234 and the second recessed portion 212, the gap between the fourth connecting portion 234 and the bottom of the groove of the second recessed portion 212 can be filled with adhesive, thereby improving the connection stability between the fourth connecting portion 234 and the second recessed portion 212.

[0071] See also Figure 6 The outer surface of one end of the connecting member 23 entering the second recessed portion 212 is provided with a glue groove 239 , and adhesive is provided in the glue groove 239 .

[0072] See also Figure 6 Exemplarily, a glue groove 239 is provided on the outer surface of the fourth connecting portion 234 . In some embodiments, the glue groove 239 is located on the side of the fourth connecting portion 234 .

[0073] It should be noted that, by providing a glue groove 239 on the outer surface of one end of the connecting member 23 that enters the second recessed portion 212 (i.e., the outer surface of the fourth connecting portion 234), the glue groove 239 can be used to store adhesive, thereby increasing the total amount of adhesive provided between the outer surface of the fourth connecting portion 234 and the inner surface of the second recessed portion 212, thereby increasing the bonding force between the fourth connecting portion 234 and the inner surface of the second recessed portion 212, and since the total area of ​​the outer surface of the fourth connecting portion 234 is increased, the contact area between the outer surface of the fourth connecting portion 234 and the adhesive is increased, thereby improving the bonding force between the adhesive and the fourth connecting portion 234, thereby improving the connection stability between the connecting member 23 and the connecting rod 21.

[0074] See also Figure 2 and Fig.10 The detachable bracket 100 further includes a screw 40, wherein the screw 40 includes a head 41 and a screw rod 42 connected to each other, and the screw rod 42 is provided with a second external thread.

[0075] See also Figure 8 and Fig. 9 The base assembly 30 includes a base 31, on which a second hollow structure 313 is provided. The second hollow structure 313 includes a fourth through hole 304, a fifth through hole 305 and a sixth through hole 306 which are sequentially arranged and interconnected in the direction from the connecting rod assembly 20 to the base assembly 30, and the cross-sectional areas of the fourth through hole 304 and the sixth through hole 306 are both larger than the cross-sectional area of ​​the fifth through hole 305.

[0076] See also Figure 7 and Fig.10 The head 41 of the screw 40 is located in the sixth through hole 306, the screw rod 42 of the screw 40 passes through the fifth through hole 305 and enters the fourth through hole 304, a fourth recessed portion 214 is provided at one end of the connecting rod assembly 20 that is away from the tray assembly 10, and a second internal thread is provided on the upper surface of the fourth recessed portion 214, and the end of the connecting rod assembly 20 that is away from the tray assembly 10 enters the fourth through hole 304, and at least a portion of the screw rod 42 of the screw 40 enters the fourth recessed portion 214 and is threadedly connected to the fourth recessed portion 214.

[0077] See also Fig.10 Exemplarily, the end of the connecting rod 21 that faces away from the tray assembly 10 enters the fourth through hole 304 .

[0078] It can be understood that, by setting the cross-sectional areas of the fourth through hole 304 and the sixth through hole 306 to be larger than the cross-sectional area of ​​the fifth through hole 305, the fourth through hole 304 can be used to accommodate the head 41 of the screw 40 to prevent the head 41 of the screw 40 from protruding from the bottom of the base 31, resulting in the detachable bracket 100 being unable to be stably placed on a plane. The sixth through hole 306 can also be used to accommodate the screw rod 42 of the screw 40 and the end of the connecting rod assembly 20 that faces away from the tray assembly 10, so that the base body of the base 31 can be used to cover the connection position of the screw 40 and the connecting rod assembly 20 to enhance the appearance of the detachable bracket 100.

[0079] See also Fig. 9 and Fig.10 , a cross section of at least a portion of the fourth through hole 304 is non-circular.

[0080] See also Figure 8 , Fig. 9 and Fig.10 , illustratively, the cross-section of one end of the fourth through hole 304 close to the fifth through hole 305 is D-shaped.

[0081] It can be understood that by setting the cross-section of at least a part of the fourth through hole 304 to be non-circular, it is possible to avoid the connection rod 21 from rotating relative to the fourth through hole 304 when the screw 40 is screwed, so that the rotation only occurs between the screw 40 and the connection rod 21, so that the user can accurately judge when the threaded connection between the screw rod 42 of the screw 40 and the connection rod 21 is completed, thereby avoiding interference with the user's judgment during the relative rotation between the connection rod 21 and the fourth through hole 304, thereby improving the user's installation experience.

[0082] See also Fig. 9 and Fig.10 The base 31 includes a plastic substrate 311 and a metal reinforcing plate 312 disposed inside the plastic substrate 311 , the metal reinforcing plate 312 is provided with the fifth through hole 305 , and the plastic substrate 311 is provided with the fourth through hole 304 and the sixth through hole 306 .

[0083] It can be understood that by arranging the metal reinforcing plate 312 inside the plastic base 311 , the weight of the base 31 can be increased by utilizing the metal reinforcing plate 312 , so that the detachable bracket 100 can be stably placed on a plane.

[0084] See also Figures 8 to 11 The base assembly 30 further includes a spring sheet 32 ​​, and the spring sheet 32 ​​is disposed between the metal reinforcing plate 312 and the connecting rod assembly 20 .

[0085] It can be understood that by arranging the spring sheet 32 ​​between the metal reinforcement plate 312 and the connecting rod assembly 20, the spring sheet 32 ​​can be used to play a buffering role in the connection process between the screw 40 and the connecting rod 21, and when looseness may occur between the screw 40 and the connecting rod 21, the spring sheet 32 ​​can apply an appropriate reaction force to the connecting rod 21, thereby reducing the possibility of loosening.

[0086] See also Fig. 9 , the spring piece 32 is connected to the metal reinforcing plate 312 .

[0087] It is understandable that by setting the spring clip 32 to be connected to the metal reinforcing plate 312, the user's operations during the installation process can be reduced, the user does not need to determine which side the spring clip 32 should be set on the metal reinforcing plate 312, and the spring clip 32 is not easily lost.

[0088] Exemplarily, the spring sheet 32 ​​and the metal reinforcing plate 312 are connected by welding.

[0089] Exemplarily, the elastic piece 32 is made of metal.

[0090] See also Fig.11 The spring piece 32 includes a connected spring piece body 321 and an inclined portion 322. An opening 329 is provided inside the spring piece body 321. The inclined portion 322 is connected to the inner edge of the opening 329. Moreover, the angle between the inclined portion 322 and the spring piece body 321 is an obtuse angle. The inclined portion 322 is located on the side of the spring piece body 321 facing the connecting rod assembly 20.

[0091] It can be understood that by providing the inner edge of the spring sheet body 321 with the inclined portion 322, since the inclined portion 322 is thin and therefore has good elasticity, when the connecting rod assembly 20 applies downward pressure to the spring sheet 32, the inclined portion 322 can bend downward to achieve a buffering effect. When the screw 40 and the connecting rod assembly 20 may become loose, the inclined portion 322 will tilt upward (gradually return to its original state) and apply an appropriate reaction force to the connecting rod assembly 20, thereby reducing the possibility of loosening between the screw 40 and the connecting rod assembly 20.

[0092] See also Fig.11 Exemplarily, the spring clip 32 includes a plurality of inclined portions 322, and the plurality of inclined portions 322 are evenly distributed on the inner edge of the spring clip body 321. A spacing area is provided between any two adjacent inclined portions 322, and the spacing area is petal-shaped, so that a plum blossom-shaped opening 329 is formed on the inner side of the spring clip body 321.

[0093] Exemplarily, the angle between the connecting rod assembly 20 and the bottom surface of the base 31 is an acute angle, such as 15°, 30°, 45°, 60°, 75°, etc.

[0094] It should be noted that the detachable bracket 100 of the embodiment of the present application may be composed of four independent modules when sold, and the four modules include a tray assembly 10, a connecting rod assembly 20, a base assembly 30 and a screw 40;

[0095] When a user wants to install the detachable bracket 100 of the embodiment of the present application, the user can follow the following steps:

[0096] When the tray assembly 10 and the connecting rod assembly 20 need to be connected, the connecting piece 23 in the connecting rod assembly 20 is inserted into the third recessed portion 123 of the threaded column 12 of the tray assembly 10, and the threaded sleeve 22 in the connecting rod assembly 20 is screwed so that the threaded column 12 gradually moves toward the direction of the first recessed portion 201 of the threaded sleeve 22 until the threaded connection between the threaded column 12 and the threaded sleeve 22 is completed, thereby achieving a fixed connection between the tray assembly 10 and the connecting rod assembly 20;

[0097] When it is necessary to connect the connecting rod assembly 20 and the base assembly 30, the screw 40 is inserted into the second hollow structure 313 on the base 31 so that the head 41 of the screw 40 is located in the sixth through hole 306, and the screw rod 42 of the screw 40 passes through the fifth through hole 305 and enters the fourth through hole 304, and one end of the connecting rod 21 is inserted into the fourth through hole 304 so that at least a portion of the screw rod 42 of the screw 40 enters the fourth recessed portion 214 on the connecting rod 21, and by screwing the head 41 of the screw 40, the screw rod 42 of the screw 40 gradually moves in a direction of deepening into the fourth recessed portion 214 until the threaded connection between the screw rod 42 and the connecting rod 21 is completed, thereby realizing the fixed connection between the connecting rod assembly 20 and the base assembly 30.
