[0002] As an important equipment for outdoor camping, emergency rescue and other fields, outdoor tents have portability and rapid deployment capabilities as core requirements. Traditional tents mostly use manually assembled skeleton structures, and the construction process requires connecting support poles one by one and fixing the tarpaulin, which is time-consuming and labor-intensive, and inefficient in bad weather or emergency situations.

[0003] In recent years, some outdoor tents with automatic deployment functions have appeared on the market. For example, they use a spring pre-tensioned structure, which utilizes the energy storage effect of spring compression to achieve automatic deployment after the lock is released; or they use a pneumatic support structure to achieve automatic deployment of the tent through inflation.

[0004] However, although the outdoor tents with automatic deployment function in the prior art can be automatically deployed, they still have obvious defects: for example, the deployment force of spring-driven tents is uncontrollable, which can easily lead to structural instability; pneumatic tents have extremely high requirements for the sealing of the pneumatic device, and there is a risk of leakage and failure. In addition, some structures require the use of electric tools when compressing the spring or inflating, which will consume outdoor electricity.

[0028] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0030] The present invention provides a power-supply type automatic unfolding mechanical arm skeleton structure for outdoor tents, including a support frame, a mechanical arm skeleton connected to the support frame, and a mobile power supply. The support frame includes a main lifting frame, a secondary lifting frame, and a mounting seat. The main lifting frame is connected to a main lifting mechanism; the secondary lifting frame is connected to the main lifting frame, and the secondary lifting mechanism is connected to the secondary lifting frame. When the main lifting mechanism is started, it is used to drive the secondary lifting frame and the secondary lifting mechanism to lift relative to the main lifting frame; the mounting seat is connected to the secondary lifting frame, and when the main lifting mechanism is started, the secondary lifting mechanism is driven to start, so as to drive the mounting seat to lift in a direction close to or away from the top of the secondary lifting frame. The mechanical arm skeleton includes at least two groups of self-folding mechanical arms symmetrically distributed on both sides of the mounting seat, and the self-folding mechanical arms are driven to unfold or fold when the mounting seat is lifted or lowered. The mobile power supply is used to power the main lifting mechanism, and a plurality of power supply ports are provided on the mobile power supply to provide power for outdoor life.

[0031] The main lifting mechanism is powered by a mobile power supply, which drives the auxiliary lifting frame and the auxiliary lifting mechanism to rise and fall relative to the main lifting frame. At the same time, the main lifting mechanism drives the auxiliary lifting mechanism to start, so as to drive the mounting seat to rise and fall relative to the auxiliary lifting frame; when the mounting seat rises and falls relative to the auxiliary lifting frame, it can drive multiple sets of self-folding mechanical arms to unfold or fold. Therefore, by starting the main lifting mechanism, the support frame can be lifted and lowered and the mechanical arm skeleton can be unfolded or retracted, so as to realize the automatic unfolding or storage of the outdoor tent. In addition, the mobile power supply is not only used to power the operation of the support frame and the mechanical arm skeleton, but also can be used as an outdoor portable power supply to power outdoor life. The automatic unfolding mechanical arm skeleton structure with high mechanical linkage and power supply greatly improves the convenience of outdoor tents.

[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of the present invention provides a power-supplying automatically deployable mechanical arm skeleton structure for an outdoor tent, comprising a support frame 1 and a mechanical arm skeleton 2 connected to the support frame 1 .

[0034] The support frame 1 includes a main lifting frame 12, a secondary lifting frame 15 and a mounting seat 17. The main lifting frame 12 is connected to a main lifting mechanism 13; the secondary lifting frame 14 is connected to the main lifting frame 12, and the secondary lifting mechanism 16 is connected to the secondary lifting frame 15. When the main lifting mechanism 13 is started, it is used to drive the secondary lifting frame 15 and the secondary lifting mechanism 16 to move up and down relative to the main lifting frame 12; the mounting seat 17 is connected to the secondary lifting frame 15, and when the main lifting mechanism 13 is started, it drives the secondary lifting mechanism 16 to start, so as to drive the mounting seat 17 to move up and down in a direction close to or away from the top of the secondary lifting frame 15; the mechanical arm skeleton 2 includes at least two groups of self-folding mechanical arms symmetrically distributed on both sides of the mounting seat 117, and when the mounting seat 17 is raised or lowered, it drives the self-folding mechanical arms to unfold or fold. The mobile power supply 3 is used to supply power to the main lifting mechanism 13, and the mobile power supply 3 is provided with multiple power supply ports to provide power for outdoor life.

[0035] Specifically, the support frame 1 is used as a supporting component of an outdoor tent to provide support for the mechanical arm skeleton 2. A main lifting frame 12 is provided with a main lifting mechanism 13, a secondary lifting frame 15 is connected to the main lifting frame 12, and a secondary lifting mechanism 16 is provided on the secondary lifting frame 15. When the main lifting mechanism 13 is started, the secondary lifting frame 15 can be driven to be lifted and lowered, and the mounting seat 17 is connected to the secondary lifting mechanism 16. Therefore, when the secondary lifting frame 15 is lifted and lowered, the secondary lifting mechanism 16 and the mounting seat 17 are driven to be lifted and lowered together. Therefore, when the main lifting mechanism 13 is started, the secondary lifting frame 15, the secondary lifting mechanism 16 and the mounting seat 17 are all lifted and lowered relative to the main lifting frame 12.

[0036] At the same time, the main lifting mechanism 13 is connected to the auxiliary lifting mechanism 16 in a transmission manner. When the main lifting mechanism 13 is started, the auxiliary lifting mechanism 16 can be driven to start. When the auxiliary lifting mechanism 16 is started, the mounting seat 17 is driven to move up and down relative to the auxiliary lifting frame 15. That is, the mounting seat 17 is lifted and down relative to the mounting platform 11, and is also lifted and down relative to the auxiliary lifting frame 15, and moves toward or away from the top of the auxiliary lifting frame 15.

[0037] Further, such as Figure 3 As shown, the mechanical arm skeleton 2 includes at least two groups of self-folding mechanical arms symmetrically distributed on both sides of the mounting seat 17. When the mounting seat 17 is raised or lowered, the self-folding mechanical arms are driven to unfold or fold. At the same time, the mobile power supply 3 can be connected to the support frame and supply power to the main lifting mechanism 13. When the main lifting mechanism 13 is started, the auxiliary lifting frame 15 can be driven to rise and fall, and the auxiliary lifting mechanism 16 can be started, thereby driving the mounting seat 17 to rise and fall, so as to unfold or fold the mechanical arm skeleton. In addition, the mobile power supply 3 can also be used as an outdoor portable power supply to provide power for outdoor life. By combining the mobile power supply 3 with the support frame 1, there is no need to carry an outdoor power supply separately, which improves the convenience of using the outdoor tent; the mobile power supply 3 can also be used as a backup power supply or emergency power supply.

[0038] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, in the embodiment of the present invention, the support frame 1 also includes a mounting platform 11 and a connecting seat 14, the main lifting frame 12 and the mobile power supply 3 are both installed on the mounting platform 11, the connecting seat 14 is connected to the main lifting frame 12, and the auxiliary lifting frame 15 is connected to the connecting seat 14; the main lifting frame 12 includes two groups of first support columns 121 symmetrically fixed on the mounting platform 11, and each group of first support columns 121 is slidably connected to the connecting seat 14, and the main lifting mechanism 13 includes a fixed shaft 131, a first driving gear 132, a first transmission belt 133 and a driving part 134. Two fixed shafts 131 are provided, which are respectively fixed on the top and bottom ends of the first support column 121; the two fixed shafts 131 are fixedly sleeved with a first driving gear 132; the first transmission belt 133 connects the two first driving wheels, and the connecting seat 14 and the auxiliary lifting mechanism 16 are both connected to the first transmission belt 133; the driving part 134 is provided on the mounting platform 11, and is used to drive the fixed shaft 131 to rotate; wherein, when the driving part 134 is started, the first driving gear 132 drives the first transmission belt 13 to operate, thereby driving the connecting seat 14 to rise and fall.

[0039] Specifically, the mounting platform 11 serves as a fixing platform for the support frame 1 and the mechanical arm frame 2. The mounting platform 11 can be fixed to the ground or on a vehicle to ensure the stability of the mechanical arm frame 2 as an outdoor tent frame. The driving mechanism and operating mechanism for providing power to the mechanical arm frame 2 can be installed on the mounting platform 11, which is convenient for user control. In addition, the mobile power supply 3 is installed on the mounting platform 11 and can be used as a counterweight for the outdoor tent, which is conducive to improving the stability of the power-supply type automatic unfolding mechanical arm frame structure during the unfolding or folding process.

[0040] Further, the first support column 121 can be a vertical pole, symmetrically fixed on the installation platform 11. The fixed shaft 131 can be between the two first support columns 121, and fixedly arranged at the lower end and the top end of the two first support columns 121 respectively; the first driving gear 132 is fixedly sleeved on the fixed shaft 131, and the upper and lower first driving gears 132 are connected by the first transmission belt 133. A connection point is provided at one place on the first transmission belt 133, and the connecting seat 14 is connected to the first transmission belt 133 through the connection point, so that when the first transmission belt 133 is running, the connecting seat 14 can be driven to move together. By controlling the position of the connection point and the running direction of the first transmission belt 133, the lifting of the connecting seat 14 can be realized; the driving part 134 is arranged on the installation platform 11, and is used to drive the fixed shaft 131 to rotate. The driving part 134 can drive the fixed shaft 131 to rotate by means of a motor and a bevel gear transmission, and the mobile power supply 3 can supply power to the motor. When the fixed shaft 131 rotates, the first driving gear 132 below is driven to rotate, thereby driving the first transmission belt 133 to operate. When the first transmission belt 133 operates, the connecting seat 14 is driven to rise and fall.

[0041] It should be noted that the first driving gears 132 can be symmetrically arranged on both sides of the fixed shaft 131, and two first driving gears 132 are arranged on each side, so that there are four first transmission belts 133 between the upper and lower fixed shafts 131, two of which are arranged on each side, and the connecting seats 14 on both sides are respectively connected to the first transmission belts 133 close to each other, and the auxiliary lifting mechanism 16 is connected to the inner first transmission belt 133, so that the connecting seats 14 on both sides maintain movement balance, which is beneficial to improving the stability of the support frame 1.

[0042] Furthermore, a first through groove 135 is opened on the first support column 121 along the length direction, and the side walls on both sides of the first through groove 135 are semi-cylindrical. A first sliding seat 136 is slidably arranged in the first through groove 135, and a first pulley 137 is arranged in the first sliding seat 136. The first pulley 137 abuts against the side wall of the first through groove 135, and the connecting seat 14 is fixedly connected to the first sliding seat 136.

[0043] For example, first through slots 135 are provided on the opposite side walls of the two groups of first support columns 121, and semi-cylindrical protrusions are formed on the opposite side walls of the first through slots 135. A plurality of first pulleys 137 may be provided in the first sliding seat 136, so that the first pulleys 137 abut against the semi-cylindrical protrusions on the side walls of the first through slots 135. When the first sliding seat 136 slides in the first through slots 135, the plurality of first pulleys 137 rotate under the friction with the semi-cylindrical protrusions on the side walls of the first through slots 135. When the first transmission belt 133 drives the connection seat 14 to rise and fall, it can drive the first sliding seat 136 to slide in the first through slots 135. The first sliding seat 136 and the first pulleys 137 can not only guide and limit the rise and fall of the connection seat 14, but also reduce the friction effect on the connection seat 14 during the rise and fall process.

[0044] like Figure 3 , Figure 4 , Figure 5 , Figure 7 As shown, in the embodiment of the present invention, the auxiliary lifting frame 15 includes a second support column 151 and a transverse fixing frame 152. The second support column 151 is fixedly connected to the connecting seats 14 on both sides, and the self-folding mechanical arm is rotatably connected to the top of the second support column 151; the transverse fixing frame 152 is connected between the two second support columns 151 and is located at the lower end of the second support column 151; wherein, the auxiliary lifting mechanism 16 is connected to the transverse fixing frame 152.

[0045] Specifically, the second support column 151 can be a vertical column fixedly connected to the connecting seat 14, the lower end of the second support column 151 is fixedly connected to the connecting seat 14, the transverse fixing frame 152 is fixedly connected to the lower ends of the two second support columns 151, and the auxiliary lifting mechanism 16 is connected to the transverse fixing frame 152. When the connecting seat 14 is raised or lowered, the second support column 151 and the transverse fixing frame 152 and the auxiliary lifting mechanism 16 connected to the second support column 151 are driven to be raised or lowered.

[0046] Furthermore, the auxiliary lifting frame 15 also includes a second sliding seat 153 and a mounting column 154. The second sliding seats 153 are fixedly connected to the connecting seats 14 on both sides; the mounting columns 154 are slidably connected to the second sliding seats 153 on both sides, and the mounting seat 17 is fixedly connected to the top of the mounting column 154.

[0047] Furthermore, the auxiliary lifting mechanism 16 includes a vertical mounting frame 161, a second driving gear 162 and a second transmission belt 163. The vertical mounting frame 161 is fixedly connected to the horizontal mounting frame 152; two second driving gears 162 are provided, which are respectively located at the upper end and the lower end of the vertical mounting frame 161, and the two second driving gears 162 are both rotatably connected to the vertical mounting frame 161; the second transmission belt 163 connects the two second driving gears 162, and the mounting column 154 is connected to the second transmission belt 163.

[0048] In addition, the operating cycle of the first transmission belt 133 is greater than the operating cycle of the second transmission belt 163. When the powered automatic deployment robotic arm skeleton structure is in a retracted state, the connection point between the second transmission belt 163 and the first transmission is located at the lower end of the first transmission belt 133, and the connection point between the mounting column 154 and the second transmission belt 163 is located at the lower end of the second transmission belt 163.

[0049] Specifically, the second sliding seat 153 is fixedly connected to the connecting seat 14, and the connecting seat 14 drives the second sliding seat 153 to slide when it is lifted or lowered, and the mounting post 154 is slidably connected to the second sliding seat 153. Therefore, when the second sliding seat 153 is lifted or lowered, the mounting post 154 will not be driven to be lifted or lowered.

[0050] At the same time, the vertical mounting frame 161 is fixedly connected to the horizontal fixing frame 152, the second driving gear 162 is rotatably connected to the vertical mounting frame 161 through a rotating shaft, the upper and lower ends of the vertical mounting column 154 are connected to the second driving gear 162, the second transmission belt 163 connects the two second driving gears 162 and forms a transmission connection, and a connection point is provided on the second transmission belt 163. The mounting column 154 is connected to the second transmission belt 163 through the connection point, that is, when the second transmission belt 163 is running, it can drive the mounting column 154 to move.

[0051] It can be understood that when the connecting seat 14 is raised or lowered, the second support column 151 and the second sliding seat 153 are driven to be raised or lowered at the same time, and the horizontal fixing frame 152 and the vertical mounting frame 161 fixedly connected to the second support column 151 are also raised or lowered at the same time, thereby driving the second driving gear 162 and the second transmission belt 163 to be raised or lowered, and at the same time, the mounting column 154 connected to the second transmission belt 163 is also raised or lowered together.

[0052] Therefore, when the connection seat 14 is lifted or lowered, the second support column 151, the second sliding seat 153, the horizontal fixing frame 152, the vertical fixing frame, the second driving gear 162, the second transmission belt 163, and the installation column 154 are driven to be lifted or lowered relative to the installation platform 11. Since the operation cycle of the first transmission belt 133 is greater than the operation cycle of the second transmission belt 163, and at the same time, the connection point between the second transmission belt 163 and the first transmission belt 133 is located at the lower end of the first transmission belt 133, and the connection point between the installation column 154 and the second transmission belt 163 is located at the upper end of the second transmission belt 163, and the connection point between the installation column 154 and the second transmission belt 163 is located at the lower end of the second transmission belt 163, therefore, when the connection point between the first transmission belt 133 and the second transmission belt 163 moves upward, the first transmission belt 133 and the second transmission belt 163 have a stroke difference, and the second transmission belt 163 can run under the drive of the first transmission belt 133. After the connection seat is lifted and lowered, the displacement distance of the connection point between the second transmission belt 163 and the first transmission belt 133 is T, and the displacement distance of the connection point between the first transmission belt 133 and the second transmission belt 163 is 2T.

[0053] The mounting column 154 and the second support column 151 are both vertically arranged, so that by controlling the position of the connection point between the mounting column 154 and the second transmission belt 163, the second transmission belt 163 can drive the mounting column 154 to rise and fall relative to the second support column 151 during operation, thereby driving the mounting seat 17 fixedly connected to the top of the mounting column 154 to move toward or away from the top of the second support column 151.

[0054] Furthermore, a second through slot 155 is opened on the mounting column 154 along the length direction, the second sliding seat 153 is located in the second through slot 155, the side walls on both sides of the second through slot 155 are semi-cylindrical, and a second pulley 156 is arranged in the second sliding seat 153, and the second pulley 156 abuts against the side wall of the second through slot 155.

[0055] Exemplarily, a second through slot 155 is provided on the side walls opposite to the two mounting posts 154 on the second sliding seat 153 connected to both sides, the second sliding seat 153 is slidably arranged in the second through slot 155, and the opposite side walls in the second through slot 155 have a semi-cylindrical protrusion, and the second sliding wheel 156 arranged in the second sliding seat 153 abuts against the semi-cylindrical protrusion on the side wall of the second through slot 155. When the mounting post 154 slides relative to the second sliding seat 153, the second pulley 156 rotates under the friction with the semi-cylindrical protrusion on the side wall of the second through slot 155. The second sliding seat 153 and the second pulley 156 can not only guide and limit the lifting and lowering of the mounting post 154, but also reduce the friction effect on the lifting seat during the lifting process.

[0056] In an embodiment of the present invention, Figure 3 , Figure 6 , Figure 8As shown, any group of self-folding mechanical arms includes a support rod 21, a connecting arm 22, a folding arm 23 and a linkage mechanism 24. The support rod 21 is rotatably connected to the mounting seat 17; the connecting arm 22 has a rotating end and a free end, the rotating end of the connecting arm 22 is rotatably connected to the top of the auxiliary lifting frame 15, and the end of the support rod 21 away from the mounting seat 17 is rotatably connected to the connecting arm 22; the folding arm 23 is movably connected to the free end of the connecting arm 22, and there are multiple groups of folding arms 23, and the multiple groups of folding arms 23 are connected in sequence; a linkage mechanism 24 is provided between the connecting arm 22 and the folding arm 23, and between two adjacent groups of folding arms 23, and the linkage mechanism 24 is used to make the connecting arm 22 and the multiple groups of folding arms 23 unfold or fold at the same time. Among them, when the mounting seat 17 is lifted or lowered, the support rod 21 drives the connecting arm 22 to rotate, and when the connecting arm 22 rotates, it drives the linkage mechanism 24 to start.

[0057] Specifically, the mechanical arm frame 2 is connected to the support frame 1, and the mechanical arm frame 2 can be used as a support frame of the outdoor tent. The mechanical arm frame 2 includes at least two groups of self-folding mechanical arms symmetrically distributed on both sides of the mounting seat 17. The number of self-folding mechanical arms is selected according to the volume and floor space requirements of the outdoor tent. For example, two groups of self-folding mechanical arms are provided on both sides of the mounting seat 17, and after unfolding, a semicircular outdoor tent can be formed.

[0058] The connecting arm 22 is a hollow tube structure, and two ends of the connecting arm 22 are two symmetrically arranged ear plates. One end of the connecting arm 22 is a rotating end, and the other end is a free end. The rotating end of the connecting arm 22 is rotatably connected to the top of the auxiliary lifting frame 15 through the ear plate. One end of the support rod 21 is rotatably connected to the mounting seat 17, and the other end is rotatably connected to the middle position of the connecting arm 22, and the position of the rotatable connection is fixed. When the auxiliary lifting mechanism 16 drives the mounting seat 17 to rise and fall relative to the auxiliary lifting frame 15, the mounting seat 17 and the top of the auxiliary lifting frame 15 produce displacement changes, so that the mounting seat 17 drives the connecting arm 22 to rotate around the connection point rotatably connected to the auxiliary lifting frame 15 by pushing the support rod 21 during the lifting process. At the same time, the free end of the connecting arm 22 is rotatably connected to the folding arm 23. The folding arms 23 may be provided in multiple groups, and the multiple groups of folding arms 23 are connected in sequence. The connection between the connecting arm 22 and the folding arm 23, as well as the connection between two adjacent groups of folding arms 23 are provided with a linkage mechanism 24. When the connecting arm 22 rotates, the linkage mechanism 24 can be driven to drive the multiple groups of folding arms 23 to rotate at the same time, thereby realizing the simultaneous expansion or folding of the connecting arm 22 and the multiple groups of folding arms 23.

[0059] For example, when it is necessary to unfold an outdoor tent, the main lifting mechanism 13 is started, and the auxiliary lifting frame 15 and the auxiliary lifting mechanism 16 are lifted together by driving the connecting seat 14. The main lifting mechanism 13 drives the auxiliary lifting mechanism 16 to move in the direction close to the top of the auxiliary lifting frame 15; during the movement of the mounting seat 17, the connecting arm 22 is driven by the support rod 21 to rotate in the direction away from the auxiliary lifting frame 15. When the connecting arm 22 rotates, it drives the linkage mechanism 24 to operate, and then drives the multiple groups of folding arms 23 to rotate, thereby realizing the automatic unfolding or folding of the self-folding mechanical arm. The automatic unfolding or folding of the outdoor tent is realized by using the support frame 1 and the mechanical arm frame 2 with high linkage, which greatly improves the convenience of the outdoor tent.

[0060] like Figure 2 , Figure 3 , Figure 6 , Figure 8 As shown, in the embodiment of the present invention, the linkage mechanism 24 includes a driving sprocket 241 and a driven sprocket 242. The driving sprocket 241 is fixedly connected to one end of the connecting arm 22 or the folding arm 23 close to the second support column 151; the driven sprocket 242 is rotatably connected to one end of the connecting arm 22 or the folding arm 23 away from the second support column 151; wherein the driving sprocket 241 and the driven sprocket 242 on the connecting arm 22 or the same group of folding arms 23 are linked by a chain, and the driven sprocket 242 on the connecting arm 22 and the driven sprocket 242 on the folding arm 23 are coaxial and fixedly connected with the driving sprocket 241 on the adjacent folding arm 23.

[0061] Specifically, both ends of the connecting arm 22 and the folding arm 23 located in the middle are connected with a driving sprocket 241 and a driven sprocket 242. Both the connecting arm 22 and the folding arm 23 can be hollow tube structures, and two symmetrical ear plates are provided at both ends, and the ear plates at the connecting ends of the connecting arm 22 and the folding arm 23 and the connecting ends of two adjacent folding arms 23 are staggered and plugged. The connecting arm 22 and the multiple groups of folding arms 23 are fixedly connected to a driving sprocket 241 at one end near the top of the second support column 151, and are rotatably connected to a driven sprocket 242 at the other end. The driven sprocket 242 on the connecting arm 22 and the driven sprocket 242 on the folding arm 23 are coaxial and fixedly connected to the driving sprocket 241 on the adjacent folding arm 23, that is, the connecting arm 22 and the folding arm 23, as well as the adjacent folding arms 23, are rotatably connected by the same rotating shaft, the rotating shaft is rotatably connected to the connecting arm 22 or the folding arm 23 at the front end, and is fixedly connected to the folding arm 23 at the rear end, and the driven sprocket 242 and the driving sprocket 241 are fixedly connected to the rotating shaft.

[0062] At the same time, the driving sprocket 241 and the driven sprocket 242 connected to the connecting arm 22, and the driving sprocket 241 and the driven sprocket 242 of the same group of folding arms 23 are all connected by chains. When the connecting arm 22 or the folding arm 23 rotates around the rotating shaft connected to one end of the driving sprocket 241, the driving sprocket 241 can be driven to rotate around the rotating shaft, and then the driven sprocket 242 can be driven to rotate through the chain, and the driven sprocket 242 can drive the driving sprocket 241 of the next section of the folding arm 23 to rotate, so that the connecting arm 22 and multiple groups of folding arms 23 can be automatically unfolded or folded.

[0063] Furthermore, when the mounting column 154 is lifted or lowered relative to the second support column 151, the mounting seat 17 is driven to lift or lower in a direction close to or away from the second support column 151. During the movement of the mounting seat 17, the connecting arm 22 is driven to rotate through the support rod 21, so as to drive the driving sprocket 241 on the connecting arm 22 to rotate. The vertical lifting movement of the mounting column 154 drives the connecting arm 22 to rotate, thereby driving the multiple groups of folding arms 23 to rotate simultaneously.

[0064] For example, when the power-supplying automatic unfolding mechanical arm skeleton structure unfolds from a retracted state, the driving unit 134 is first started, and the driving unit 134 drives the fixed shaft 131 at the lower end, namely the first driving gear 132, to rotate, so as to drive the first transmission belt 133 to operate; when the first transmission belt 133 operates, it drives the connecting seat 14 and the second support column 151 to rise, so as to increase the overall height of the outdoor tent; while the first transmission belt 133 operates, it drives the second transmission belt 163 to operate, and when the second transmission belt 163 operates, it drives the mounting column 154 to approach the top of the second support column 151, thereby driving the mounting seat 17 to approach the top of the second support column 151; during the process of the mounting seat 17 approaching the top of the second support column 151, the connecting arm 22 is pushed to rotate by the support rod 21. When the connecting arm 22 rotates, the driving sprocket 241 connected to the connecting arm 22 also rotates around the axis, and drives the driven sprocket 242 to rotate through the chain, and when the driven sprocket 242 rotates, it drives the folding arm 23 at the rear end to rotate. Thereby, the support frame 1 and the mechanical arm frame 2 can be automatically unfolded, and the mechanical arm frame 2 serves as an outdoor tent frame, thereby realizing automatic unfolding of the outdoor tent.

[0065] The embodiment of the present invention also provides an outdoor tent, including the above-mentioned power-supply type automatic deployment mechanical arm skeleton structure. The use of the power-supply type automatic deployment mechanical arm skeleton structure as the skeleton of the outdoor tent can realize the automatic deployment or storage of the outdoor tent, has the advantages of high mechanical linkage and convenience, and can also improve the structural stability of the outdoor tent skeleton. At the same time, the mobile power supply 3 can not only be used to power the drive unit 134, but also can be used as a portable battery to provide daily electricity for outdoor camping when camping outdoors. Integrating the mobile power supply 3 on the outdoor tent is convenient for overall carrying, and there is no need to carry an outdoor battery separately. It can reduce the weight of the outdoor tent and facilitate the movement and installation of the outdoor tent.
