[0002] Existing backpacks, especially those used for outdoor activities or professional fields, often have certain limitations. These backpacks usually only provide fixed carrying methods and limited functionality, and cannot adapt to the needs of different users or carry different types of electronic devices.

[0003] Specifically, existing backpacks often lack flexibility in their bracket designs. The bracket's angle and position are typically fixed, limiting the user's ability to adjust the backpack to their specific needs. For example, when an antenna or other electronic device needs to be mounted on a backpack, existing brackets lack sufficient angle adjustment, impacting device performance and user experience.

[0004] Furthermore, the functional expansion capabilities of existing backpacks are limited. Most lack effective expansion interfaces, preventing users from adding additional functional devices such as communication devices, navigation equipment, or other specialized electronic equipment as needed. This restricts the range and flexibility of backpacks, making them unable to meet the diverse needs of users.

[0005] Therefore, in order to solve the above problems, we propose a multifunctional carrying device. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-4 An embodiment of the present invention discloses a multifunctional carrying device, specifically comprising a back frame 2 connected to a shoulder strap assembly 1, wherein the shoulder strap assembly 1 is used to be worn on the body when carrying the device;

[0030] The back of the back frame 2 is fixedly connected to two support arms 3, a bracket 4 is provided between the tops of the two support arms 3, and a reversing and adjustment component 5 is provided between the bracket 4 and the support arms 3;

[0031] A leg member 6 is also fixedly connected to the lower side of the back of the backpack 2. The leg member 6 has a bearing portion 61. The bearing portion 61 can be used to place electronic equipment. The leg member 6 is an L-shaped structure as a whole, and its bent end can be used as a supporting foot.

[0032] In some embodiments, the shoulder strap assembly 1 of the present invention includes a backrest 11 fixed to the front end of the back frame 2. The backrest 11 is used to improve the comfort of the user's back when carrying the backpack. Specifically, the backrest 11 can be set as a flexible member such as a sponge pad, which conforms to the ergonomic design and meets the comfort requirements.

[0033] The front end of the backrest 11 is further connected to two shoulder straps 12 and two binding straps 13 , and the ends of the two binding straps 13 are connected via a first buckle assembly 14 .

[0034] On the basis of the above embodiment, both ends of the shoulder strap 12 in this embodiment are fixed to the backrest 11, and a connecting belt 15 is also fixed to the middle part of the shoulder strap 12. The ends of the two connecting belts 15 are connected and fixed by a second buckle assembly 16. Of course, the first buckle assembly 14 and the second buckle assembly 16 described in this embodiment have the same structure, and both adopt the plug-in method of male buckle and female buckle to achieve mutual connection.

[0035] Specifically, when carrying the device, the user can wear the two straps 12 on the shoulders, bend the two straps 13, and fix them around the abdomen through the first buckle assembly 14. This can greatly improve the stability of carrying the device. Of course, in order to prevent the straps 12 from slipping off the shoulders, two connecting straps 15 are also used in this embodiment to restrain the two straps 12 from each other. Specifically, the two connecting straps 15 can be connected and fixed through the second buckle assembly 16, which further enhances the carrying stability of the device.

[0036] In a preferred embodiment, the reversing and adjusting assembly 5 of the present invention includes a U-shaped member 51 , and a rotating disk 52 is fixedly connected to the side of the U-shaped member 51 ;

[0037] The turntable 52 is rotatably connected to the end of the support arm 3 , and a locking structure is provided between the turntable 52 and the support arm 3 .

[0038] Preferably, the locking structure in this embodiment includes a locking bolt 53 passing through the outside of the support arm 3, and a plurality of locking holes 54 are circumferentially distributed on the end face of the turntable 52. The end of the locking bolt 53 is threadedly connected to the locking hole 54, and a spring 55 is also provided between the locking bolt 53 and the support arm 3.

[0039] That is to say, in this embodiment, a design of multiple locking holes 54 is adopted, and the threads of different locking holes 54 are locked and fixed by locking bolts 53 to adjust the rotation angle of the U-shaped part 51, thereby adjusting and fixing different inclination angles of the bracket 4. When carrying electronic equipment, different angles can be adjusted when the antenna is installed on the top of the bracket 4. In addition, the spring 55 is used to prevent the locking bolt 53 from falling off, thereby ensuring the working stability of the reversing and adjustment component 5.

[0040] Furthermore, the bracket 4 in this embodiment includes two arms 41, a mounting plate 42 connected between the tops of the two arms 41, and a fixing plate 43 connected between the bottoms of the two arms 41. The bottom of the fixing plate 43 has two pairs of side wings 44. Each pair of side wings 44 is mounted on the outside of the U-shaped member 51 and is connected and fixed by fasteners. As a preferred embodiment, the fasteners described in this embodiment are also configured as bolts. Of course, to prevent the bolts from falling out, a spring can also be placed between the bolts and the side wings 44. In this embodiment, the bracket 4 is connected and fixed by a locking member, so that the position of the bracket 4 can be rotated and replaced during disassembly, thereby further improving the adjustability of the entire bracket 4. In addition, in this embodiment, a locating pin is fixedly installed in the middle of the fixing plate 43, and a locating hole is opened in the middle of the U-shaped member 51. The locating pin is inserted into the locating hole to provide a good connection and support effect when replacing or rotating the bracket 4.

[0041] It should be noted that, in this embodiment, a number of expansion interfaces 21 are distributed on the end face of the back frame 2, and the support arm 3 and the leg member 6 are connected to the back frame 2 through fasteners and the expansion interface 21. Preferably, the expansion interface 21 in this embodiment is configured as a planar portion having multiple threaded holes. In this embodiment, each expansion interface 21 adopts a threaded hole design with four matrix parts. Of course, the fasteners are also configured as bolts, and the above-mentioned parts are locked and fixed with the threaded holes by bolts to achieve convenient replaceable expansion operations.

[0042] In addition, in order to reduce the overall weight, the back frame 2 in this embodiment is a molded carbon fiber part. Of course, the support arm 3 and the support leg part 6 and other parts can also be designed with carbon fiber parts. This method is a conventional means used by technicians in the field and will not be elaborated here.

[0043] In summary, the carrying device in the present invention realizes the adjustment and fixation of different inclination angles of the bracket 4 through the design of the reversing and adjusting component 5. When carrying electronic equipment, different angles can be adjusted when the antenna is installed on the top of the bracket 4. At the same time, the reversing and adjusting component 5 can also be used to disassemble and replace the entire bracket 4, which further improves the adjustability of the entire bracket 4. Secondly, the back frame 2 adopts the design of multiple expansion interfaces 21, which can expand multiple functional devices as needed, carry various forms of electronic equipment, and is light in weight, high in strength, and has a wide range of uses.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
