Description

Technical Field

[0001] The invention relates to the technical field of mobile power supplies, and in particular to a stably placed mobile power supply. Background Art

[0002] With the development of modern society and the accelerated pace of life, people are increasingly pursuing a higher quality of life, not only to meet their basic daily needs, but also to yearn for a natural, healthy and diverse lifestyle. Among them, outdoor camping, as a form of activity that combines leisure, adventure and closeness to nature, has been favored by more and more people in recent years. A variety of outdoor activities, such as photography, music playing, lighting and cooking, all rely on stable and high-power mobile power support to ensure worry-free power supply during the activities, which greatly enriches the camping experience.

[0003] In addition, in certain work scenarios, such as outdoor construction, agricultural operations, or temporary activities, traditional power supply methods are inconvenient due to the long distance and the need to pull wires. Mobile power, with its portability, flexibility, and instant power supply capabilities, has become an ideal power solution for these practical tools. It can effectively shorten the power access distance, avoid the safety hazards and increased costs caused by long-distance wiring, and enable various equipment in the work area to operate smoothly, greatly improving work efficiency and convenience.

[0004] However, although mobile power supplies play a vital role in outdoor activities and operations, they still have some shortcomings that cannot be ignored in actual use. Especially in outdoor camping environments, people need to find a flat ground to place barbecue grills or lay picnic mats in order to enjoy a more comfortable and convenient camping experience. Mobile power supplies are limited by uneven terrain, soft ground or lack of fixed support, making it difficult to place them stably and easy to tip over or slide, which not only affects the stability of power supply, but also may cause safety hazards. Similarly, in rooftop construction, due to the lack of a flat placement platform, it is difficult for existing mobile power supplies to find a suitable fixed position, limiting the choice of work areas. Summary of the invention

[0005] In order to overcome the disadvantages of being restricted by the environment and having unstable placement, the present invention provides a mobile power source with stable placement, aiming to solve the above disadvantages.

[0006] A stably placed mobile power source comprises a shell, a battery assembly and a handle, wherein the battery assembly is arranged in the shell, the shell is provided with a handle, and the shell further comprises a mounting frame, a ball panel, a support assembly, a limiting assembly and a positioning assembly, wherein the bottom of the shell is connected with the mounting frame, the bottom of the mounting frame is connected with the ball panel, the ball panel is provided with a support assembly for adjusting the placement of the shell, the shell is provided with a limiting assembly for stabilizing the supporting assembly, and the shell is provided with a positioning assembly for fixing the limiting assembly.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0030] Embodiment: A mobile power source that is stably placed, such as Figure 1-Figure 10 As shown, it includes a shell 1, a battery assembly 2 and a handle 3. The battery assembly 2 is arranged in the shell 1. The handle 3 is rotatably connected to the shell 1. Different plugs are arranged on the shell 1, and the user can select a suitable plug according to the power demand. It also includes a mounting frame 4, a spherical panel 5, a support assembly 6, a limiting assembly 7 and a positioning assembly. The bottom of the shell 1 is connected to the mounting frame 4, the bottom of the mounting frame 4 is connected to the spherical panel 5, the top of the spherical panel 5 is a spherical surface, and the spherical panel 5 is provided with a supporting assembly 6 for adjusting the placement of the shell 1, a limiting assembly 7 for stabilizing the supporting assembly 6 is arranged in the shell 1, and a positioning assembly for fixing the limiting assembly 7 is arranged in the shell 1.

[0031] like Figure 3 and Figure 4As shown, the support assembly 6 includes a ball-jointed arc plate 61 and a support arc plate 62. The ball-jointed arc plate 61 is slidably connected to the ball panel 5. The bottom of the mounting frame 4 is set to a spherical surface. The upper and lower side surfaces of the ball-jointed arc plate 61 are respectively fitted with the bottom surface of the mounting frame 4 and the top surface of the ball panel 5. Four support arc plates 62 are evenly connected to the bottom of the ball-jointed arc plate 61. The support arc plate 62 and the inner spherical surface of the ball-jointed arc plate 61 have co-curved surfaces, that is, the support arc plate 62 can also fit with the top surface of the ball panel 5. A number of limiting grooves 63 are provided on the ball-jointed arc plate 61. When the mobile power supply is placed stably, the support arc plate 62 supports the mobile power supply and pushes the ball-jointed arc plate 61 to move upward. The top of the ball-jointed arc plate 61 contacts with the limiting assembly 7. When the mobile power supply is suspended in the air, the ball-jointed arc plate 61 naturally hangs down, and the ball-jointed arc plate 61 is separated from the limiting assembly 7.

[0032] like Figure 5-Figure 7 As shown, the limiting assembly 7 includes a connecting rod 71, a gear 72, a rack 73, a hydraulic cylinder 74, a sealing plate 75, a delivery pipe 76, a stepped ring pipe 77 and a limiting piece 78. The top of the shell 1 is rotatably connected to the connecting rod 71, the handle 3 is fixedly connected to the connecting rod 71, and the handle 3 is rotated 90 degrees to fit the top surface of the shell 1. A gear 72 is connected to both ends of the connecting rod 71. Two hydraulic cylinders 74 are installed in the shell 1. The two hydraulic cylinders 74 are symmetrically distributed. A sealing plate 75 is slidably connected in the two hydraulic cylinders 74. The sealing plate 75 is tightly connected to the hydraulic cylinder 74, and the liquid in the hydraulic cylinder 74 will not overflow from the top. The top of the sealing plate 75 is connected to the rack 73, which is vertically arranged and meshed with the gear 72. The two racks 73 are located on the same side of the two gears 72, so that the two sealing plates 75 move synchronously. The bottom side of the mounting frame 4 is connected to The stepped annular tube 77 is composed of a circular tube that is successively reduced from bottom to top. The distance between the stepped annular tube 77 and the ball joint arc plate 61 is close at each place. One end of the delivery tube 76 is connected to the hydraulic cylinder 74, and the other end is connected to the stepped annular tube 77. The delivery tube 76 and the stepped annular tube 77 are filled with liquid. A plurality of limiting members 78 for limiting the ball joint arc plate 61 are arranged on the bottom side of the stepped annular tube 77. The limiting member 78 includes an extension tube 781, a piston rod 782, a first elastic member 783 and a rubber ball head 784. A plurality of extension tubes 781 are connected to the bottom of the stepped annular tube 77. The piston rod 782 is slidably connected in the extension tube 781. The bottom of the piston rod 782 is connected to a rubber ball head 784. The first elastic member 783 is sleeved on the piston rod 782. One end of the first elastic member 783 is connected to the extension tube 781, and the other end is connected to the rubber ball head 784. Figure 7 A retaining ring is provided in the extension tube 781 for connecting the first elastic member 783 .

[0033] like Figure 5 and Figure 8As shown, the positioning assembly includes a limit rod 8 and a second elastic member 81. The limit rod 8 is slidably connected to the inner sides of the left and right ends of the shell 1. The second elastic member 81 is sleeved on the limit rod 8. One end of the second elastic member 81 is connected to the limit rod 8, and the other end is connected to the shell 1. Eight spherical grooves 82 are circumferentially arranged at both ends of the connecting rod 71. The limit rod 8 cooperates with the spherical grooves 82, so that the connecting rod 71 is limited by the limit rod 8.

[0034] When power support is needed in the outdoor environment, the user can easily take out the mobile power supply through the handle 3, and then simply insert the plug into the socket of the shell 1, and the battery assembly 2 can provide a stable power supply for the electrical equipment. The mobile power supply needs to select a suitable placement location. The user needs to find a flat ground and then put the mobile power supply down vertically. At this time, the support arc plates 62 of the support assembly 6 are in contact with the ground at the same time, providing a stable support foundation for the mobile power supply. If the ground is tilted, there is a sequence in which the support arc plates 62 contact the ground. The support arc plates 62 will push the ball-jointed arc plates 61 to rotate on the ball panel 5 until all the support arc plates 62 are completely in contact with the ground to adapt to the tilt angle of the ground and ensure that the mobile power supply remains vertical.

[0035] When the user confirms that the mobile power supply has been stably placed, the user will then turn the handle 3, which will drive the connecting rod 71 to rotate, thereby meshing the gear 72 with the rack 73. As the gear 72 rotates, the rack 73 will push the sealing plate 75 in the hydraulic cylinder 74 to move. During the movement, the sealing plate 75 will squeeze the liquid in the hydraulic cylinder 74, which will then flow into the stepped ring tube 77 along the delivery pipe 76 and finally act on the limiting member 78. The limiting member 78 includes an extension tube 781, a piston rod 782, a first elastic member 783 and a rubber ball head 784. When the liquid in the hydraulic cylinder 74 flows into the stepped ring tube 77 through the delivery pipe 76 and further pushes the limiting member 78, the piston rod 782 will slide in the extension tube 781, stretching the first elastic member 783, and the rubber ball head 784 corresponding to the limiting groove 63 will move to the limiting groove 63 to cooperate, and the rubber ball head 784 not corresponding to the limiting groove 63 will abut against the surface of the ball-jointed arc plate 61. This matching mode not only limits the further rotation of the ball-jointed arc plate 61, but also effectively stabilizes the placement state of the mobile power supply.

[0036] At the same time, during the rotation of the connecting rod 71, the spherical groove 82 provided thereon will be separated from the limiting rod 8. At this time, the limiting rod 8 will be compressed under the action of the second elastic member 81. When the handle 3 is rotated 90 degrees, the limiting rod 8 is aligned with the spherical groove 82 again, and the rebound force of the second elastic member 81 will push the limiting rod 8 into the spherical groove 82, thereby limiting the further rotation of the connecting rod 71, ensuring that the stable placement state of the mobile power supply is maintained.

[0037] When the mobile power supply is not in use, the handle 3 is rotated in the opposite direction, and the sealing plate 75 is pulled upward through the gear 72 and the rack 73 to draw the liquid upward. The first elastic member 783 rebounds to disengage the rubber ball head 784 from the ball-jointed arc plate 61. The mobile power supply is then lifted and placed on a transport vehicle. After the supporting arc plate 62 contacts the placement plane, the ball-jointed arc plate 61 is pushed to rotate and reset on the ball panel 5.

[0038] like Fig. 9 and Fig.10 As shown, it also includes a fixing rod 9, a supporting foot 91 and a docking block 92. The fixing rod 9 is connected inside the supporting arc plate 62, and the fixing rod 9 is rotatably connected to the supporting foot 91. When the supporting foot 91 is in contact with the bottom of the ball panel 5, the end surface of the supporting foot 91 and the supporting arc plate 62 are co-curved. The bottom of the ball panel 5 is connected to the docking block 92, and the end of the supporting foot 91 is provided with a docking groove 93. The supporting foot 91 is limited by the cooperation of the docking block 92 and the docking groove 93. The docking block 92 is made of rubber.

[0039] If the placement plane is flat, the support foot 91 will be in a folded state, fit with the bottom of the ball panel 5, and its rotation will be limited by the cooperation of the docking block 92 and the docking slot 93. When the mobile power supply is moving, the support foot 91 will not rotate around the fixed rod 9 and fall due to its own gravity. If the placement plane is tilted, the user can flip the support foot 91 downward to disengage it from the docking block 92, and make the arc surface of the support foot 91 coplanar with the support arc plate 62, thereby extending the support length to adapt to a larger tilt angle. When the support foot 91 is not needed, turn it upward, and the docking block 92 will automatically cooperate with the docking slot 93 to limit its rotation.

[0040] like Fig.11 As shown, it also includes a connecting ring 10 and a cleaning brush head 11. The bottom of the shell 1 is connected to the connecting ring 10, and the inner side of the connecting ring 10 is provided with a plurality of cleaning brush heads 11. The cleaning brush heads 11 are slidably connected to the ball joint arc plate 61.

[0041] like Figure 4 and Fig. 9 As shown, a rubber pad 12 is also included, and the end surfaces of the supporting arc plate 62 and the supporting foot 91 are both connected to the rubber pad 12.

[0042] During the rotation and reset of the ball arc plate 61, the cleaning brush head 11 on the connecting ring 10 will slide in contact with its upper surface to remove surface contaminants. This not only ensures the cleanliness of the ball arc plate 61, but also ensures the stable squeezing effect between the rubber ball head 784 and the ball arc plate 61. At the same time, the support arc plate 62 and the support foot 91 are both equipped with rubber pads 12 to increase the friction between the placement plane, further improving the stability of the mobile power supply placement, and after the support foot 91 is flipped downward, the rubber pads 12 on the support arc plate 62 cooperate with the support foot 91 to ensure the stability of the support foot 91 and prevent the support foot 91 from swinging freely.

[0043] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
