[0034] In outdoor activities such as hiking, off-roading or cycling, especially in the current atmosphere where users love to share their lives on the Internet, users often need to carry a large amount of equipment and gear to complete outdoor activities that last for days, weeks or even months. During this period, they also need to record a large number of videos and photos and other materials during the outdoor activities, and they also need to reserve a large amount of power for various electronic devices. Therefore, they need to carry a lot of supplies, such as clothes, sleeping bags, food, cameras, drones, lighting and medicines, etc. These things require multiple types of backpacks to store them separately. When carrying these supplies by themselves, especially when they need to record videos while hiking or cycling, these complex actions cannot be completed by the user's hands alone. An efficient outdoor supply carrying solution is needed to meet the above needs.

[0035] This application provides a multifunctional backpack stand 100, see Figures 1 to 3 , Figure 1 This is a structural diagram of an embodiment of a multifunctional backpack rack provided by this application. Figure 2yes Figure 1 Schematic diagram of the structure of the multifunctional rod group. Figure 3 yes Figure 2 Schematic diagram of the exploded structure of the multifunctional rod group.

[0036] The multifunctional backpack frame 100 includes a main frame 10 and a multifunctional pole group 20, wherein the main frame 10 stores the backpack, and the multifunctional pole group 20 includes a connecting component 22 and a telescopic rod 24. One end of the connecting component 22 is fixed to the main frame 10, and the bottom end of the telescopic rod 24 is fixed to the other end of the connecting component 22. The top end of the telescopic rod 24 is used for a detachable connection functional device (not shown in the figure). The connecting component 22 allows the telescopic rod 24 to move relative to the main frame 10.

[0037] The main frame 10 can be used to store various types of backpacks, such as material bags, equipment bags, and battery packs. The main frame 10 includes a shoulder strap 12 for the user to use. The user can use the shoulder strap 12 to carry the main frame 10 and the various backpacks loaded thereon together to efficiently carry various backpacks and free up their hands.

[0038] The multifunctional pole group 20 has multiple uses. For example, a mobile phone or camera can be installed on it, and a fixed position required by the user can be provided to record the video of the user during hiking, crossing or cycling; or, a lighting lamp can be installed on it to continuously provide the user with lighting for the road ahead; or, a navigator can be installed on it so that the user can view the navigation route in real time; or, it can also be used as a support stick to support the bottom surface when the user stops, thereby providing a certain amount of assistance and reducing the weight of the user when standing and resting.

[0039] The multifunctional pole group 20 includes a connecting component 22 and a telescopic pole 24, wherein the connecting component 22 can be connected to the side of the main frame 10, so that when the user carries the main frame 10 on his back, the telescopic pole 24 can be extended forward from one of the left and right sides of the user, so that the installed camera can take pictures of the user's face. Of course, the telescopic pole 24 can also be extended above the user's head, so that the camera installed thereon can record the scene of the user's forward journey from an overhead perspective.

[0040] Optionally, the connection assembly 22 may also be installed on the back of the main frame 10 facing away from the user.

[0041] The telescopic rod 24 can be extended and shortened to adjust the appropriate length. The telescopic rod 24 includes a plurality of rod bodies that are arranged in a nested manner. The plurality of rod bodies can be contracted to form the length of a single rod body, or can be extended to form a combined length of the plurality of rod bodies.

[0042] The user can adjust the length of the telescopic rod 24 based on needs. For example, when not in use, the telescopic rod 24 can be retracted to the minimum length and placed on the main frame 10, or fixed to a fixed position on the main frame 10; for example, when the user needs to take a bird's-eye view or a bird's-eye view, the length of the telescopic rod 24 can be adjusted based on the user's height and the required shooting field of view.

[0043] In this embodiment, the connecting component 22 allows the telescopic rod 24 to move relative to the main frame 10. In other words, the connecting component 22 can determine whether the telescopic rod 24 can move relative to the main frame 10, that is, the connecting component 22 can lock the position of the telescopic rod 24, and can be unlocked to allow the telescopic rod 24 to move relative to the main frame 10.

[0044] Among them, when the connecting component 22 locks the position of the telescopic rod 24, the telescopic rod 24 can maintain its current posture unchanged, for example, maintaining a downward or upward shot while moving; when the connecting component 22 is unlocked, the telescopic rod 24 can move freely relative to the main frame 10, for example, rotate relative to the main frame 10 in a plane, or rotate relative to the main frame 10 in a hemispherical space, or swing relative to the main frame 10, etc.

[0045] In this embodiment, the connecting component 22 allows the telescopic rod 24 to rotate 0 to 360 degrees within a plane relative to the main frame 10, thereby allowing the telescopic rod 24 to have a great degree of freedom, realizing shooting or lighting in various postures and various angles, and can also be supported downward on the bottom surface to help the user reduce the weight when standing.

[0046] The present application arranges a multifunctional pole group 20 on a main frame 10 that can store a backpack, wherein the multifunctional pole group 20 includes a connecting component 22 and a telescopic pole 24. The connecting component 22 allows the telescopic pole 24 to move relative to the main frame 10. The top end of the telescopic pole 24 can be detachably connected to functional devices such as a mobile phone, a camera or a lighting lamp, so that the multifunctional pole group 20 can provide various camera positions that follow the user's movements and free the user's hands.

[0047] Optionally, one group of the multifunctional rod groups 20 is installed on the main frame 10, or two or three groups of the multifunctional rod groups 20 are provided on the main frame 10. The present application does not limit the number.

[0048] In this embodiment, a group of multifunctional pole groups 20 are provided on both sides of the main frame 10, so that two camera positions can be provided in real time, such as overhead shooting and downward shooting, etc., or a camera is installed on one for upward shooting, and a lighting lamp is installed on the other to provide lighting, thereby further improving the types of matching of various functional devices and achieving richer and more interesting gameplay.

[0049] The top end of the telescopic rod 24 can be detachably connected to a functional component, such as a screw connection, a clamping connection, a snap connection or a magnetic attraction functional component.

[0050] For example, the top end of the telescopic rod 24 is detachably connected to a corresponding bracket (not shown), such as a mobile phone bracket, camera bracket, gimbal or stabilizer, etc., which can clamp, snap or magnetically attract the corresponding functional components; or, a fixed threaded hole is provided on the lighting lamp, and a stud is provided on the top end of the telescopic rod 24, so that the lighting lamp can be screwed to the top end of the telescopic rod 24.

[0051] The above-mentioned various types of brackets can refer to various types of mobile phone brackets or gimbals and other equipment currently on the market; of course, the top end of the telescopic rod 24 can also be set as a clamping component in today's selfie sticks, which can further provide the functional device with additional adjustable freedom of movement when clamping the functional device. The clamping component can be swung and adjusted relative to the main body of the telescopic rod 24 and can be buckled on the main body of the telescopic rod 24.

[0052] Among them, functional devices may include mobile phones, cameras, lighting, navigators, metal detectors or reflectors, etc. These suitable devices can be installed on the top of the telescopic rod 24 to play their roles in appropriate scenarios.

[0053] See Figures 2 to 4 ,in Figure 4 yes Figure 2 Schematic diagram of the cross-sectional structure of the connecting component Figure 4 yes Figure 2 Schematic diagram of the cross-sectional structure of the connecting components.

[0054] In this embodiment, the connecting assembly 22 includes a fixed base 220, a movable part 222 and a first locking part 224. The fixed base 220 is fixedly connected to the main frame 10, the movable part 222 is movably connected to the fixed base 220, the telescopic rod 24 is connected to the movable part 222, and the first locking part 224 is located on the side of the movable part 222 away from the fixed base 220 and is connected to the fixed base 220 through a fastener; wherein, the first locking part 224 allows the movable part 222 to move relative to the fixed base 220 or not.

[0055] Among them, the fixed seat 220 can be fixedly connected to the main frame 10 by fasteners such as screws, pins or rivets, and the movable part 222 can be rotatably connected or hinged to the fixed seat 220, such as a ball joint. The telescopic rod 24 is connected to the movable part 222 so that it can move relative to the fixed seat 220. The first locking part 224 can be adjusted to allow the movable part 222 to move relative to the fixed seat 220.

[0056] The first locking member 224 can lock the movable member 222 by applying pressure to the movable member 222, and allow the movable member 222 to move relative to the fixed base 220 after the pressure is released; or the first locking member 224 can limit the movable member 222 from moving relative to the fixed base 220 by being connected to the fixed base 220 or the main frame 10, and allow the movable member 222 to move relative to the fixed base 220 when the connection with the fixed base 220 or the main frame 10 is released.

[0057] Optionally, the first locking member 224 is passed through the through hole of the movable member 222 , and a plurality of threaded holes distributed in an annular pattern are provided on the fixing seat 220 or the main frame 10 . The first locking member 224 locks the movable member 222 by connecting to the threaded holes.

[0058] In this embodiment, the fixed seat 220 includes a gear shaft 221, and the movable part 222 includes a turntable 223 and a locking tooth 225 movably arranged on the turntable 223. The turntable 223 is rotatably arranged on the gear shaft 221, and the locking tooth 225 is used to cooperate with the tooth gap on the gear shaft 221 to preliminarily lock the position of the movable part 222 relative to the fixed seat 220 when the external force stops driving the movable part 222.

[0059] When the first locking member 224 is unlocked, the user directly rotates the telescopic rod 24, thereby driving the turntable 223 on the movable member 222 to rotate around the axis of the gear shaft 221, and the locking teeth 225 can be moved and cyclically inserted into the tooth gaps on the gear shaft 221, that is, when rotating, the locking teeth 225 can retract when they hit the teeth of the gear shaft 221, and can rebound and insert into the tooth gap when corresponding to the tooth gap, one of which can make the user rotate the telescopic rod 24 more rhythmically and with better feedback. The other is that when the telescopic rod 24 is stopped from rotating, the locking teeth 225 can preliminarily lock the movable member 222 and the telescopic rod 24 connected thereto by being inserted into the tooth gap, preventing the movable member 222 and the telescopic rod 24 from rotating freely, that is, the telescopic rod 24 and the movable member 222 only start to rotate when driven by force, and can stop at the current position after not being driven, further improving the user's operation convenience, and effectively avoiding the problem of easy position change after adjustment.

[0060] See Figures 3 to 5 , Figure 5 yes Figure 2 Schematic diagram of the structure of the moving parts.

[0061] The turntable 223 is provided with a center hole, and the side wall of the turntable 223 is provided with a stop groove connected to the center hole. The lock tooth 225 is movably installed in the stop groove. The connecting component 20 also includes an elastic member (not shown) supporting the lock tooth 225, so that the lock tooth 225 can partially extend into the center hole to cooperate with the tooth gap of the gear shaft 221, and when the turntable 223 rotates, the lock tooth 225 can retract when it encounters the teeth of the gear shaft 221, that is, it compresses the elastic member and exits the center hole and retracts into the stop groove. When corresponding to the tooth gap, it can rebound and insert into the tooth gap under the elastic force support of the elastic member.

[0062] The fixed seat 220 also includes a seat body 226 connected to the gear shaft 221, and the seat body 226 is provided with a first corrugated surface 227 on the side facing the turntable 223, and the turntable 223 is provided with a second corrugated surface 228 matching the first corrugated surface 227 on the side facing the seat body 226; the gear shaft 221 is a hollow shaft, and the first locking piece 224 is provided on the side of the turntable 223 away from the seat body 226, and the fastener is installed on the seat body 226 and is threadedly connected to the first locking piece 224 through the hollow channel on the gear shaft 221; wherein, the first locking piece 224 is tightened with the fastener, and pressure is applied to the turntable 223, so that the first corrugated surface 27 fits with the second corrugated surface 228, thereby fastening the movable part 222 and the fixed seat 220; the first locking piece 224 is loosened from the fastener to allow the turntable 223 to rotate relative to the gear shaft 221.

[0063] The seat body 226 is fixed to the main frame 10 by screws, and the gear shaft 221 is arranged on the boss of the seat body 226. The boss has a first corrugated surface 227 on the side facing the turntable 223. The first corrugated surface 227 is a plurality of corrugations arranged in a circle around the gear shaft 221 on the boss, and the turntable 223 has a second corrugated surface 228 on the side facing the seat body 226. The corrugations of the first corrugated surface 227 and the second corrugated surface 228 are the same, and the peaks and troughs on the first corrugated surface 227 and the second corrugated surface 228 can fit together, so that when the first locking member 227 applies pressure to the turntable 223, the fitted first corrugated surface 227 and the second corrugated surface 228 can strengthen the prevention of the turntable 223 from rotating relative to the seat body 226, so that the movable member 222 can be locked and fixed more reliably to avoid fixation failure caused by loosening.

[0064] Furthermore, the movable part 222 also includes a mounting sleeve 201 connected to the outside of the turntable 223 and a second locking part 202 connected to the mounting sleeve 21. The telescopic rod 24 is connected to the mounting sleeve 201, and the second locking part 202 allows the telescopic rod 24 to be telescopic relative to the mounting sleeve 201.

[0065] The second locking member 202 can be locked or unlocked by turning the knob. When the second locking member 202 is locked, the telescopic rod 24 cannot be further extended. When the second locking member 202 is unlocked, the telescopic rod 24 can be freely extended.

[0066] Optionally, the second locking member 202 can be a screw threaded onto the mounting sleeve 201. By turning the second locking member 202, the second locking member 202 can be pressed against the telescopic rod 24 in the mounting sleeve 201, thereby locking the telescopic rod 24; the second locking member 202 can be unlocked by turning the knob in the opposite direction.

[0067] In this embodiment, a plurality of movable gaps are provided on the wall at the top of the mounting sleeve 201, so that a plurality of elastic walls 203 are formed at the top of the mounting sleeve 201. The second locking member 202 is threadedly connected to the top of the mounting sleeve 201, and a guide slope is provided on the inner wall of the second locking member 202. When the second locking member 202 is tightened relative to the mounting sleeve 201, the guide slope presses the plurality of elastic walls 203 together to lock the telescopic rod 24, thereby fixing the length of the telescopic rod 24. When the second locking member 202 is loosened relative to the mounting sleeve 201, the guide slope releases the pressure on the plurality of elastic walls 203, thereby allowing the telescopic rod 24 to be extended and retracted relative to the mounting sleeve 201.

[0068] In other words, the second locking member 202 is tightened to fix the length of the telescopic rod 24 ; the second locking member 202 is loosened in the opposite direction to allow the telescopic rod 24 to be extended and retracted, thereby adjusting the length of the telescopic rod 24 .

[0069] The first locking member 224 can be used to control whether the telescopic rod 24 can rotate relative to the fixed base 220, and the second locking member 202 can be set to control whether the telescopic rod 24 can continue to extend or maintain the current length, so that the adjustment of the multi-function rod group 20 in each degree of freedom is controllable, and thus the use posture formed by the adjustment of the multi-function rod group 20 can be maintained, such as supporting the camera's downward or upward shooting posture, thereby freeing both hands, allowing the functional device to follow the user's movement in real time with an appropriate use posture, and provide real-time functional support to the user without the user having to hold it personally, which saves physical energy and does not interfere with the user's activities and movements.

[0070] See also Figure 1 and Figure 6 ,in Figure 6 yes Figure 1 Schematic diagram of the structure of the middle main frame.

[0071] In this embodiment, the main frame 10 includes a bottom plate bracket 11, a side support frame 12, a support side plate 13 and a top bracket 14, one end of the two side support frames 12 are respectively connected to the two sides of the bottom plate bracket 11, and the other ends of the two side support frames 12 are respectively connected to the two sides of the top bracket 14, and the support side plate 13 connects the two side support frames 12 and is relatively located between the top bracket 14 and the bottom plate bracket 11; wherein the main frame 10 defines a first backpack space, a second backpack space and a third backpack space, the first backpack space is defined by the bottom plate bracket 11, between the two side support frames 12 and one side of the support side plate 13, the second backpack space is defined by the support side plate 13, between the two side support frames 12 and the top bracket 14, and the third backpack space is defined by the other side of the support side plate 12.

[0072] The first backpack compartment can be used to store the main backpack 30, which has a large capacity and can hold a variety of items such as food, medicine, clothing, and sleeping bags. The second backpack compartment can be used to store the equipment bag 40, which can be used to store drones or camera equipment. The third backpack compartment can be used to store the battery box 50, which contains a large-capacity battery and provides various electrical interfaces such as USB, Type-C, and power strips. It can also provide AC and DC power to meet the power needs of various electronic devices.

[0073] Specifically, the main backpack 30 is installed in the first backpack space; the equipment bag 40 is installed in the second backpack space and is detachably connected to the side support frame 12 and / or the top support 14; the battery box 50 is installed in the third backpack space and is detachably connected to the support side panel 13.

[0074] The main backpack 30 is further detachably connected to the bottom bracket 11 and / or the side support frame 12 and / or the supporting side panel 13, for example, by using straps or buckles to fix the main backpack 30 to the bottom bracket 11 and / or the side support frame 12 and / or the supporting side panel 13.

[0075] The main backpack 30 can also take advantage of the special structure of the first backpack space and be placed directly in the first backpack space without the need for additional fixing means. The bottom bracket 11, the side support frame 12, the supporting side panel 13 and the back of the user when carrying the backpack can all provide support, thereby limiting the position of the main backpack 30 and preventing the main backpack 30 from falling off.

[0076] The bottom frame 11 is a plate-like structure that supports the main backpack 30 and provides a secure support on the ground, table, or countertop when the user removes the multifunctional backpack stand 100. The bottom frame 11, side support frames 12, supporting side panels 13, and top frame 14 are all rigid frames, made of various hard materials such as stainless steel, aluminum alloy, or copper alloy. These frames provide sufficient load-bearing strength and rigidity to prevent the main frame 10 from deforming during use, potentially causing the backpacks to be squeezed against each other. This eliminates the risk of damage to the equipment stored within each backpack.

[0077] The first backpack space and the second backpack space are separated by the supporting side panel 13, wherein the battery box 50 can be detachably connected to the supporting side panel 13 to avoid applying pressure to the main backpack 30, thereby preventing the main backpack 30 and the battery box 50 from being squeezed against each other; the equipment bag 40 can be detachably connected to the side support frame 12 and / or the top bracket 14, and supported by the top of the supporting side panel 13 to avoid applying pressure to the main backpack 30 and the battery box 50, thereby preventing the equipment bag 40 from squeezing the main backpack 30 and the battery box 50.

[0078] See Figure 1 and Figure 6 The tops of the main backpack 30 and the battery box 50 do not extend beyond the tops of the supporting side panels 13, and the supporting side panels 13 can support the equipment bag 40, thereby preventing the equipment bag 40 from squeezing the main backpack 30 and the battery box 50, and effectively protecting the items stored in the equipment bag 40, the main backpack 30, and the battery box 50. Furthermore, the bottom of the battery box 50 does not extend beyond the bottom of the supporting side panels 13, and the battery box 50 is connected to the supporting side panels 13, with the supporting side panels 13 fully providing support to the battery box 50, thereby preventing the bottom of the battery box 50 from squeezing the storage portion 34 of the main backpack 30. The supporting side panels 13 also isolate the battery box 50 from the backpack portion 32 of the main backpack 30, thereby preventing the battery box 50 and the backpack portion 32 from squeezing each other.

[0079] In the present application, the main frame 10 defines a first backpack space, a second backpack space and a third backpack space. The main backpack 30, the equipment bag 40 and the battery box 50 stored in each backpack space are separated from each other by the supporting side panels 13 to avoid mutual squeezing, thereby effectively protecting the items in each backpack and avoiding damage to the items in each backpack due to mutual squeezing.

[0080] In this embodiment, the main frame 10 further includes a shoulder strap 15 connecting at least the top support 14 and the bottom support 11. The shoulder strap 15 can also be connected to the two side support frames 12 to effectively limit the main backpack 30. The shoulder strap 15 is located on an isolation pad on the main backpack 30, away from the supporting side panels 13. This isolation pad has a certain degree of elasticity, which can increase the user's comfort when carrying the backpack. Furthermore, the isolation pad can be designed to have multiple storage compartments, which can store items such as raincoats and medicines.

[0081] The equipment bag 40 can be detachably connected to the side support frame 12 and / or the top support 14 by means of straps or buckles; the battery box 50 can also be detachably connected to the supporting side panel 13 by means of straps or buckles.

[0082] The main backpack 30, equipment bag 40 and battery box 50 are reasonably installed in the backpack spaces of the main frame 10, so that the overall volume formed by the main backpack 30, equipment bag 40 and battery box 50 is small, which is convenient for users to carry outdoors; and the main backpack 30, equipment bag 40 and battery box 50 can all be removed from the main frame 10, making it convenient to take items in and out at any time. Equipment that needs to be used frequently can be placed in the equipment bag 40, and the battery box 50 can also charge functional devices that need power or charging at any time to ensure the battery life of equipment such as drones, cameras or mobile phones.

[0083] Furthermore, if Figure 6 As shown, a plurality of weight-reducing holes are provided on the supporting side panel 13 for installing the battery box 50, and weight-reducing holes may also be provided on the bottom bracket 11, thereby further lightweighting the main frame 10 to reduce the weight when the user carries it. Of course, after these weight-reducing holes are provided, the main frame 10 still has sufficient strength to support the main backpack 30, the equipment bag 40 and the battery box 50.

[0084] In this embodiment, Figure 1 As shown, the main backpack 30 includes a backpack part 32 and a storage part 34 connected to the backpack part 32. The backpack part 32 and the storage part 34 are both supported on the bottom plate bracket 11. The backpack part 32 and the battery box 50 are respectively located on both sides of the supporting side plate 13. The battery box 50 is located between the equipment bag 40 and the storage part 34. The equipment bag 40 is also supported by the battery box 50 and the backpack part 32.

[0085] By further limiting the structure of the main backpack 30 and the distribution positions of the various bags, the main backpack 30, the equipment bag 40 and the battery box 50 integrated on the host 10 can form a larger backpack shape as a whole, which is convenient for users to carry and has higher space utilization. The center of gravity of the multifunctional backpack frame 100 is more stable.

[0086] The storage portion 34 can serve as an independent small space, or it can be connected to the backpack portion 32. The sum of the thickness of the battery box 50 and the backpack portion 32, the sum of the thickness of the backpack portion 32 and the storage portion 34, and the thickness of the equipment bag 40 in the same direction are roughly the same, and the width in the width direction is also roughly the same. Therefore, the main backpack 30, the equipment bag 40 and the battery box 50 can be stacked on the main frame 10 to form a large backpack shape, which is extremely convenient for users to carry.

[0087] In this embodiment, the multifunctional rod set 20 is connected to the side support frame 12, wherein the fixing base 220 is fixedly connected to the side support frame 12. Specifically, the multifunctional rod set 20 is connected to both side support frames 12.

[0088] See also Figure 1 、 Figure 6 and Figure 7 ,in Figure 7 yes Figure 6 Schematic diagram of the structure of the middle sliding member and the claw mechanism.

[0089] In this embodiment, a sliding member 42 is provided on the equipment bag 40, and a sliding guide rail 120 and a pawl mechanism 122 are provided on the side support frame 12 and / or the top support frame 14. The sliding member 42 is used to be slidably assembled in the sliding guide rail 120 and can be locked by the pawl mechanism 122. The pawl mechanism 122 is also used to be driven to release the lock of the sliding member 42.

[0090] The cooperation between the sliding guide rail 120 and the pawl mechanism 122 can realize the quick locking and unlocking of the sliding member 42 on the equipment bag 40, making the connection and disassembly between the equipment bag 40 and the main frame 10 very convenient and avoiding cumbersome operation steps.

[0091] The sliding guide rail 120 can guide the sliding member 42 into the locked position and be directly locked by the claw mechanism 122, so that the equipment bag 40 can be quickly fixed to the main frame 10; when unlocking is required, the user can manually operate the claw mechanism 122 to release the lock on the sliding member 42, so that the equipment bag 40 can be removed smoothly.

[0092] In this embodiment, the sliding guide rail 120 also stops and limits the non-sliding direction of the sliding member 42. Specifically, the sliding guide rail 120 has a sliding groove, the edges of which are provided with relatively bent ribs. The sliding member 42 enters the sliding groove from one end and slides along the sliding groove. The ribs can limit the sliding of the sliding member 42 within the sliding groove and stop and limit the sliding member 42 in the non-sliding direction, preventing the sliding member 42 from falling out of the non-sliding direction of the sliding groove. Therefore, when the sliding member 42 is slidably assembled on the sliding guide rail 120, it can reliably trigger the pawl mechanism 122 to lock it.

[0093] The pawl mechanism 122 includes a mounting plate 121, a pawl 123 rotatably connected to the mounting plate 121, and a torsion spring (not shown) installed between the pawl 123 and the mounting plate 121. The mounting plate 121 is connected to the side support frame 12 and / or the top bracket 14. One end of the pawl 123 is located in the slide groove of the sliding guide rail 120 under the support of the torsion spring. When the sliding member 42 is slidably assembled in the sliding guide rail 120, it can press the pawl 123 and enter the slide groove of the sliding guide rail 120. After the pawl 123 is reset with the support of the torsion spring, it can lock the sliding member 42. One end of the pawl 123 is also used to exit the slide groove of the sliding guide rail 120 under active drive, thereby releasing the lock on the sliding member 42.

[0094] In other words, when the sliding member 42 is slidably assembled in the sliding guide rail 120, the sliding member 42 can be locked without the need for additional actions to complete the locking, making the fixation of the equipment bag 40 very efficient and convenient; and when unlocking, the user only needs to manually move the claw 123 to quickly release the lock on the sliding member 42, making the disassembly between the equipment bag 40 and the main frame 10 also very convenient.

[0095] See also Figure 1 、 Figure 6 and Figure 8 ,in Figure 8 yes Figure 1 Schematic diagram of the battery box structure. In this embodiment, the battery box 50 is detachably connected to the support side panel 13. The battery box 50 includes an interface panel 52, which is provided with multiple electrical interfaces 522 and ventilation areas 524 located on both sides of the multiple electrical interfaces 522. The ventilation areas 524 are connected to the interior of the battery box 50.

[0096] The multiple types of electrical interfaces 522 include USB interfaces, type-c interfaces and power strip interfaces. The multiple types of electrical interfaces 522 may include DC interfaces and AC interfaces. The multiple types of electrical interfaces 522 may also include other types of electrical interfaces. This application does not impose any specific restrictions on this.

[0097] By integrating multiple types of electrical interfaces 522 and ventilation areas 524 on the interface panel 52, two ventilation areas 524 are used for heat dissipation, one ventilation area 524 can be used for air intake, and the other ventilation area 524 can be used for air exhaust. This allows for efficient heat dissipation at multiple types of electrical interfaces 522, and also facilitates waterproofing treatment together. That is, it is beneficial to use waterproofing treatment on the interface panel 52, so that various types of electrical interfaces 522 and ventilation areas 524 can be waterproofed together, greatly reducing the difficulty of waterproofing the battery box 50.

[0098] Compared with dispersing the ventilation area 524 and the electrical interfaces 522 in different positions, more places need to be waterproofed, which makes it cumbersome to use. It is easy to miss the waterproofing of the ventilation area 524 and the electrical interfaces 522 when not in use. In the present application, multiple types of electrical interfaces 522 and ventilation areas 524 are directly integrated on the same interface panel 52, making the waterproofing relatively simple and efficient. The interface panel 52 can be directly waterproofed, the operation is simple, and waterproofing omissions can be effectively avoided.

[0099] Furthermore, the battery box 50 also includes a sealing cover (not shown) detachably connected to the interface panel 52 to cover the various electrical interfaces 522 and the ventilation area 524, thereby simultaneously protecting the electrical interfaces 522 and the ventilation area 524 from water.

[0100] The sealing cover can be snapped onto the interface panel 52 to simultaneously cover the electrical interface 522 and the ventilation area 524 ; alternatively, the sealing cover can be snapped onto the interface panel 52 or the battery box 50 to simultaneously cover the electrical interface 522 and the ventilation area 524 .

[0101] In this embodiment, the battery box 50 has a recessed area 53 formed at the interface panel 52 . The interface panel 52 forms the bottom of the recessed area 53 . The sealing cover is buckled into the recessed area 53 , thereby simultaneously covering the electrical interface 522 and the ventilation area 524 .

[0102] Furthermore, the sealing cover can be rotatably connected to the battery box 50 and can be snapped onto the recessed area 53, thereby preventing the sealing cover from being lost.

[0103] See Figure 1 、 Figure 6 and Figure 9 ,in Figure 9 yes Figure 8 Schematic diagram of the structure of the battery box from another perspective.

[0104] In this embodiment, the battery box 50 includes a box body 54 and a locking member 56 connected to the box body 54. The box body 54 is slidably assembled on the supporting side plate 13 of the main frame 10 and is locked with the supporting side plate 13 of the main frame 10 through the locking member 56; wherein the locking member 56 can be driven to release the locking relationship with the supporting side plate 13 of the main frame 10 to allow the box body 54 to slide relative to the main frame 10.

[0105] Optionally, a dovetail slide rail may be provided on the support side panel 13, and a dovetail slide groove compatible with the dovetail slide rail may be provided on the box body 54, so that the battery box 50 can be slidably assembled on the support side panel 13 to achieve rapid positioning and preliminary installation, and after installation in place, the box body 54 is fixed to the support side panel 13 by the locking member 56. After the locking member 56 is locked to the support side panel 13, the battery box 50 will be restricted and fixed to the main frame 10.

[0106] In this embodiment, Figure 6 and Figure 9 As shown, a first slide rail 132 is provided on the supporting side panel 13 of the main frame 10, and a second slide rail 57 is provided on the side of the box body 54 facing the main frame 10, which is slidably connected to the first slide rail 132. By using the slide rails to slide between the box body 54 and the supporting side panel 13, the first slide rail 132 and the second slide rail 57 can slide together and can also be locked to prevent them from falling off. The slide rails can also provide more precise guidance, allowing the battery box 50 to be reliably installed in the preset position.

[0107] The first slide rail 132 and the second slide rail 57 have the same structure, but the slidingly matched first slide rail 132 and the second slide rail 57 are arranged oppositely so that they can be hooked and connected to each other and can slide along a defined sliding direction.

[0108] Specifically, the supporting side panels 13 of the main frame 10 are provided with two first slide rails 132 with grooves facing each other, and the box body 54 is provided with two second slide rails 57 with grooves facing each other. The first slide rail 132 is slidably set in the grooves of the second slide rails 57, and at the same time, the second slide rails 57 are slidably set in the grooves of the first slide rails 132, so that the two groups of matching first slide rails 132 and second slide rails 57 can also restrain each other to prevent the first slide rails 132 and the second slide rails 57 in any group from falling off each other, so that they can only slide along the limited direction under the limitation of the slide rails and cannot be separated from the other directions, further increasing the sliding stability and reliability.

[0109] A slide groove 134 is provided on the supporting side plate 13 of the main frame 10, and the first slide rail 132 is arranged on the bottom surface of the slide groove 134, and one end along the extension direction of the slide groove 134 is open; the second slide rail 57 enters the slide groove 134 from the opening of the slide groove 134 and is slidably connected to the first slide rail 132 under the guidance of the slide groove 134.

[0110] The slide groove 134 can play a guiding role, and the second slide rail 57 can be efficiently slidably assembled with the first slide rail 132 along the slide groove 134, thereby reducing the alignment difficulty during installation by the user and improving the user's operational convenience.

[0111] See also Figure 6 、 Figures 8 to 11In this embodiment, a lock hole 136 is provided on the supporting side plate 13 of the main frame 10; a guide groove 540 is provided on the side of the box body 54 facing the main frame 10, and the lock member 56 includes a sliding seat 560 and a lock tooth 562 and a manual unlocking portion 564 provided on the sliding seat 560. The sliding seat 560 is slidably provided in the guide groove 540 and an elastic member (not shown) supporting the sliding seat 560 is also provided in the guide groove 540. A stopper 542 for stopping the sliding seat 560 is also installed at the notch of the guide groove 540. The lock tooth 562 is provided on the sliding seat 560. 2 can at least partially pass over the stopper 542 and extend outward, and the manual unlocking portion 564 is exposed from the notch in the side wall of the guide groove 540. The locking tooth 562 can be retracted into the guide groove 540 by the pressure of the supporting side plate 13 of the main frame 10, and after being aligned with the locking hole 136, it is supported by the elastic force of the elastic member and inserted into the locking hole 136. The manual unlocking portion 564 can be driven to release the locking relationship between the locking tooth 562 and the locking hole 136, thereby allowing the box body 54 to slide relative to the supporting side plate 13 of the main frame 10.

[0112] The locking member 56 is slidably installed in the guide groove 540, and the elastic member provides elastic support force, so that the locking tooth 562 can extend outward beyond the stop member 542, and after it is aligned with the lock hole 136, it can be directly inserted into the lock hole 136, thereby completing the locking of the battery box 50, so that the battery box 50 can be efficiently installed on the support side panel 13.

[0113] When unlocking, the user can manually operate the manual unlocking portion 564 to disengage the locking teeth 562 from the locking hole 136 and release the lock, thereby allowing the box body 54 to slide relative to the supporting side plate 13 of the main frame 10 to remove the battery box 50.

[0114] By adopting the cooperation between the lock hole 136 and the lock member 56, the battery box 50 can be easily locked on the supporting side panel 13, and unlocking is also very convenient, which greatly reduces the difficulty of loading and unloading the battery box 50 on the main frame 10 and is very convenient for users to load and unload the battery box 50.

[0115] Furthermore, a handle 544 is provided on the box body 54 to facilitate the user to take the battery box 50 and to facilitate the installation and removal of the battery box 50 on the supporting side plate 13 .

[0116] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application.
