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

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be noted that the orientation terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0031] Embodiment: A mobile power supply with stable placement, as Figures 1-10 shown, includes a housing 1, a battery assembly 2 and a handle 3. A battery assembly 2 is arranged inside the housing 1, a handle 3 is rotatably connected to the housing 1, and different plugs are arranged on the housing 1. Users can select appropriate plugs according to their power consumption requirements. It also includes a mounting bracket 4, a spherical panel 5, a support assembly 6, a limiting assembly 7 and a positioning assembly. The mounting bracket 4 is connected to the bottom inside the housing 1, the spherical panel 5 is connected to the bottom of the mounting bracket 4, the top of the spherical panel 5 is spherical, and a support assembly 6 for adjusting the placement of the housing 1 is arranged on the spherical panel 5. A limiting assembly 7 for stably supporting the support assembly 6 is arranged inside the housing 1, and a positioning assembly for fixing the limiting assembly 7 is arranged inside the housing 1.

[0032] As Figure 3 and Figure 4As shown in the figure, the support assembly 6 includes a ball joint arc plate 61 and a support arc plate 62. The ball joint arc plate 61 is slidably connected to the ball panel 5. The bottom of the mounting bracket 4 is spherical. The upper and lower sides of the ball joint arc plate 61 are respectively in contact with the bottom surface of the mounting bracket 4 and the top surface of the ball panel 5. Four support arc plates 62 are evenly connected to the bottom of the ball joint arc plate 61. The support arc plates 62 and the inner spherical surface of the ball joint arc plate 61 are co-curved, that is, the support arc plates 62 can also be in contact with the top surface of the ball panel 5. A number of limiting grooves 63 are provided on the ball joint arc plate 61. When the mobile power supply is placed stably, the support arc plates 62 support the mobile power supply, pushing the ball joint arc plate 61 to move upward. The top of the ball joint arc plate 61 contacts the limiting component 7. When the mobile power supply is suspended, the ball joint arc plate 61 hangs down naturally, and the ball joint arc plate 61 is separated from the limiting component 7.

[0033] As Figures 5-7 shown, the limiting component 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 member 78. The connecting rod 71 is rotatably connected to the top of the housing 1. The handle 3 is fixedly connected to the connecting rod 71. After the handle 3 is rotated 90 degrees, it is in contact with the top surface of the housing 1. A gear 72 is connected to both ends of the connecting rod 71. Two hydraulic cylinders 74 are installed in the housing 1. The two hydraulic cylinders 74 are symmetrically distributed left and right. A sealing plate 75 is slidably connected in each of the two hydraulic cylinders 74. The sealing plate 75 is closely 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 a rack 73. The rack 73 is vertically arranged and meshes with the gear 72. Both 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 bracket 4 is connected to a stepped ring pipe 77. The stepped ring pipe 77 is composed of circular pipes that gradually decrease from bottom to top. The distance between each part of the stepped ring pipe 77 and the ball joint arc plate 61 is similar. One end of the delivery pipe 76 is communicated with the hydraulic cylinder 74, and the other end is communicated with the stepped ring pipe 77. The delivery pipe 76 and the stepped ring pipe 77 are already filled with liquid. A number of limiting members 78 for limiting the ball joint arc plate 61 are provided on the bottom side of the stepped ring pipe 77. The limiting member 78 includes an extension pipe 781, a piston rod 782, a first elastic member 783 and a rubber ball head 784. A number of extension pipes 781 are connected to the bottom of the stepped ring pipe 77. A piston rod 782 is slidably connected in the extension pipe 781. The bottom of the piston rod 782 is connected to a rubber ball head 784. A first elastic member 783 is sleeved on the piston rod 782. One end of the first elastic member 783 is connected to the extension pipe 781, and the other end is connected to the rubber ball head 784. Referring Figure 7 to, a retaining ring is provided in the extension pipe 781 for connecting the first elastic member 783.

[0034] As Figure 5 and Figure 8As shown in the figure, the positioning component includes a limiting rod 8 and a second elastic member 81. The inner sides of the left and right ends of the housing 1 are both slidably connected with the limiting rod 8. A second elastic member 81 is sleeved on the limiting rod 8. One end of the second elastic member 81 is connected to the limiting rod 8, and the other end is connected to the housing 1. Eight spherical grooves 82 are circumferentially arranged at both ends of the connecting rod 71. The limiting rod 8 cooperates with the spherical grooves 82, so as to limit the connecting rod 71 through the limiting rod 8.

[0035] When the outdoor environment requires power support, the user can conveniently take out the mobile power supply through the handle 3. Subsequently, simply insert the plug into the socket of the housing 1, and the battery assembly 2 can provide a stable power supply for the electrical equipment. The mobile power supply needs to be placed in a suitable position. The user needs to find a flat ground and then vertically place the mobile power supply. At this time, the supporting arc plates 62 of the supporting component 6 contact the ground simultaneously, providing a stable supporting foundation for the mobile power supply. If the ground is inclined, there is a sequence in which the supporting arc plates 62 contact the ground. The supporting arc plates 62 will push the spherical joint arc plate 61 to rotate on the spherical panel 5 until all the supporting arc plates 62 are completely in contact with the ground to adapt to the inclination angle of the ground and ensure that the mobile power supply remains vertical.

[0036] When the user confirms that the mobile power supply is stably placed, then the handle 3 is rotated. The handle 3 drives the connecting rod 71 to rotate, and then the gear 72 meshes 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 of the sealing plate 75, the liquid in the hydraulic cylinder 74 will be squeezed. These liquids will then flow into the stepped ring pipe 77 along the delivery pipe 76 and finally act on the limiting member 78. The limiting member 78 includes an extension pipe 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 pipe 77 through the delivery pipe 76 and further pushes the limiting member 78, the piston rod 782 will slide in the extension pipe 781, stretching the first elastic member 783, and the rubber ball head 784 corresponding to the limiting groove 63 will move into the limiting groove 63 for cooperation, while the rubber ball head 784 not corresponding to the limiting groove 63 will abut against the surface of the spherical joint arc plate 61. This cooperation method not only limits the further rotation of the spherical joint arc plate 61, but also effectively stabilizes the placement state of the mobile power supply.

[0037] At the same time, during the rotation of the connecting rod 71, the spherical grooves 82 provided thereon will disengage from the limiting rod 8. At this time, the limiting rod 8 will be compressed under the action of the second elastic member 81. After the handle 3 rotates 90 degrees, the limiting rod 8 is aligned with the spherical groove 82 again, and the resilience of the second elastic member 81 will push the limiting rod 8 into the spherical groove 82, thereby restricting the further rotation of the connecting rod 71 and ensuring that the stable placement state of the mobile power supply is maintained.

[0038] When the mobile power supply is not in use, turn the handle 3 in the reverse direction. By means of the gear 72 and the rack 73, the sealing plate 75 is pulled upward to extract the liquid upward. The first elastic member 783 rebounds, causing the rubber ball head 784 to disengage from the spherical joint arc plate 61. Subsequently, lift the mobile power supply and place it on the transportation tool. After the supporting arc plate 62 contacts the placement plane, the spherical joint arc plate 61 is pushed to rotate and reset on the spherical panel 5.

[0039] As Figure 9 and Figure 10 shown, it further includes a fixing rod 9, a supporting foot 91 and a docking block 92. A fixing rod 9 is connected inside the supporting arc plate 62. The fixing rod 9 is rotatably connected with the supporting foot 91. When the supporting foot 91 fits against the bottom of the spherical panel 5, the end face of the supporting foot 91 and the supporting arc plate 62 are coplanar. A docking block 92 is connected to the bottom of the spherical panel 5. A docking groove 93 is provided at the end of the supporting foot 91. 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.

[0040] If the placement plane is flat, the supporting foot 91 will be in a folded state, fitting against the bottom of the spherical panel 5, and its rotation is restricted by the cooperation of the docking block 92 and the docking groove 93. When the mobile power supply is moving, the supporting foot 91 will not rotate and fall around the fixing rod 9 due to its own gravity. If the placement plane is inclined, the user can turn the supporting foot 91 downward to disengage it from the docking block 92 and make the arc surface of the supporting foot 91 coplanar with the supporting arc plate 62, thereby extending the supporting length to adapt to a larger inclination angle. When the supporting foot 91 is not needed, turn it upward, and the docking block 92 will automatically cooperate with the docking groove 93 to restrict its rotation.

[0041] As Figure 11 shown, it further includes a connecting ring 10 and a cleaning brush head 11. A connecting ring 10 is connected to the bottom of the housing 1. A plurality of cleaning brush heads 11 are arranged on the inner side surface of the connecting ring 10. The cleaning brush heads 11 are slidably connected with the spherical joint arc plate 61.

[0042] As Figure 4 and Figure 9 shown, it further includes a rubber pad 12. Rubber pads 12 are connected to both the end face of the supporting arc plate 62 and the supporting foot 91.

[0043] During the process of the spherical joint arc plate 61 rotating and resetting, the cleaning brush head 11 on the connecting ring 10 will slide into contact with its upper surface to remove the pollutants on the surface. This not only ensures the cleanliness of the spherical joint arc plate 61, but also guarantees the stable extrusion effect between the rubber ball head 784 and the spherical joint arc plate 61. At the same time, both the support arc plate 62 and the support feet 91 are equipped with rubber pads 12 to increase the friction force with the placement plane, further improving the stability of the mobile power supply placement. After the support feet 91 are turned downward, through the cooperation of the rubber pads 12 on the support arc plate 62 and the support feet 91, the stability of the support feet 91 can be ensured to prevent the support feet 91 from swinging freely.

[0044] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
