Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage battery technology, specifically a mobile energy storage battery device. Background Technology
[0002] Mobile energy storage battery devices, as portable energy supply equipment, have been widely used in outdoor operations, emergency rescue, camping and travel, and power supply for small equipment. With their flexible mobility, they fill the gap in fixed power supply and provide stable power support for areas without grid coverage. Whether it is temporary lighting for engineering teams, power supply for equipment at rescue sites, or power needs for families outdoors, their convenience is highly favored.
[0003] To improve mobility, existing devices generally have a roller structure at the bottom. However, most current mainstream rollers use an arc-shaped contact surface design. While this structure can reduce bumps during movement, it reveals a flaw during the device fixing stage. The contact area between the arc-shaped contact surface and the ground is limited, forming only line contact or small-area point contact, which cannot provide sufficient static friction. This design flaw makes the device prone to displacement under slight external force, which may not only cause damage to the equipment but also loosen the wiring during charging or power supply, leading to the risk of power outage. In severe cases, it may even cause safety hazards due to wire pulling. Summary of the Invention
[0004] The purpose of this invention is to provide a mobile energy storage battery device to solve the problems mentioned in the background art.
[0005] This mobile energy storage battery device includes a main body, a base (located on one side of the main body), multiple sets of omnidirectional wheels (located on one side of the base), two mounting brackets (slidably mounted on one side of the base), and multiple support legs (located on one side of the mounting brackets). When the omnidirectional wheels are on the ground, the device is supported by them, allowing for easy movement. When a fixed position is required, the support legs replace the omnidirectional wheels in contact with the ground and support the device. This avoids the problem of displacement caused by the curved contact surface design of the omnidirectional wheels. An adjustment assembly includes a fixed plate and two sets of support plates. The fixed plate is fixedly mounted inside the base, and the support plates are slidably mounted inside the base. The unit comprises a fixed plate with two sets of connecting plates slidably disposed on one side, a fixed column disposed on one side of the connecting plate, two sets of swing plates rotatably disposed on one side of the fixed plate, one side of the swing plates slidably disposed outside the fixed column, and a half gear disposed on the other side of the swing plates, a support plate with both sides penetrating the base and fixedly disposed with two sets of mounting brackets respectively, a support plate with two sets of protrusions disposed on one side of the support plate, the protrusions being semi-elliptical, a slider disposed on one side of the connecting plate, a central shaft slidably disposed inside the slider, two sets of pulleys rotatably disposed outside the central shaft, the outer side of the pulleys contacting one side of the protrusions, and a drive assembly disposed on one side of the fixed plate, and one side of the drive assembly meshing with the half gear.
[0006] Preferably, two sets of balance bars are slidably arranged inside the support plate, and both ends of the balance bars are fixed inside the base.
[0007] Preferably, two sets of first springs are provided on one side of the support plate, and the end of the first spring away from the support plate is located inside the base.
[0008] Preferably, two sets of placement racks are provided on one side of the support plate, and the protrusion is provided on one side of the placement rack, and the protrusion is semi-elliptical.
[0009] Preferably, the fixing plate has two sets of mounting seats on one side, and limit rods are provided on both sides of the mounting seats. The connecting plate is slidably disposed on the outside of the two sets of limit rods.
[0010] Preferably, a push plate is slidably provided on the outer side of the limiting rod, a disc is fixedly provided on the outer side of the limiting rod, and a second spring is provided between the disc and the push plate.
[0011] Preferably, the swing plate is provided with a movable shaft on the side away from the fixed column, and one end of the movable shaft is fixedly disposed on one side of the fixed plate.
[0012] Preferably, the drive assembly includes a support base, which is disposed on one side of a fixed plate. A rotary motor is disposed on one side of the support base. A threaded pipe is key-connected to the output end of the rotary motor. A sleeve is screwed onto the outer side of the threaded pipe. A movable plate is disposed on one side of the sleeve. Two sets of racks are disposed on one side of the movable plate, and the racks mesh with half gears.
[0013] By adopting the above technical solution, the problem of displacement caused by the arc-shaped contact surface design of the caster wheel can be avoided.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This mobile energy storage battery device, through the cooperation between the pulley and the protrusion, will push the support plate to move longitudinally by pushing the protrusion to move longitudinally when the pulley moves laterally. The displacement of the support plate will push the support leg to move longitudinally by pushing the mounting bracket. At this time, the support leg will contact the ground and replace the universal wheel to support the device. This avoids the situation where the universal wheel adopts an arc-shaped contact surface design, which makes the device very easy to shift. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0020] Please see Figure 1-7 This utility model provides a technical solution: a mobile energy storage battery device, including a body 1, a base 4 fixedly connected to one side of the body 1, four sets of universal wheels 5 provided on one side of the base 4, mounting frames 6 slidably connected to both sides of the base 4, two sets of support legs 7 fixedly connected to one side of the mounting frame 6, an adjustment component 2 provided inside the base 4, and one side of the adjustment component 2 fixedly connected to the mounting frame 6, and a drive component 3 provided on one side of the adjustment component 2.
[0021] Please see Figure 2-7The adjusting assembly 2 includes a fixed plate 201 and two sets of support plates 204. The fixed plate 201 is fixedly connected to the inside of the base 4. Two sets of movable shafts 219 are fixedly connected to one side of the fixed plate 201. A swing plate 212 is rotatably connected to the outside of the movable shafts 219. A half gear 213 is fixedly connected to one side of the swing plate 212. Two sets of connecting plates 203 are slidably connected to one side of the fixed plate 201. A fixed column 211 is fixedly connected to one side of the connecting plate 203, and the side of the swing plate 212 away from the half gear 213 is slidably connected to the outside of the fixed column 211. Two sets of sliders 206 are fixedly connected to one side of the connecting plate 203. A central shaft 210 is slidably connected inside the slider 206, and both ends of the central shaft 210 pass through it. The slider 206 has two sets of pulleys 209 rotatably connected to the outside of the central shaft 210. The support plate 204 is slidably connected inside the base 4. Both sides of the support plate 204 penetrate the base 4 and are fixedly connected to two sets of mounting brackets 6 respectively. Two sets of placement brackets 205 and two sets of first springs 208 are fixedly connected to one side of the support plate 204. The end of the first spring 208 away from the support plate 204 is fixedly connected to the inside of the base 4. A protrusion 202 is fixedly connected to one side of the placement bracket 205. The protrusion 202 is semi-elliptical and one side of the protrusion 202 contacts the outside of the two sets of pulleys 209. Two sets of balance bars 207 are slidably connected inside the support plate 204, and both ends of the balance bars 207 are fixedly connected to the inside of the base 4.
[0022] Specifically, in order to maintain the balance of the connecting plate 203, a mounting base 217 is fixedly connected to one side of the fixed plate 201. Limiting rods 214 are fixedly connected to both sides of the mounting base 217, and the connecting plate 203 is slidably connected to the outside of the two sets of limiting rods 214. Thus, on the one hand, the limiting rods 214 maintain the balance of the connecting plate 203 during movement, preventing the connecting plate 203 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the connecting plate 203. On the other hand, the limiting rods 214 restrict the direction of the connecting plate 203, preventing the device from failing due to misalignment of the connecting plate 203, and ensuring the normal use of the device.
[0023] Meanwhile, in order to enable the connecting plate 203 to move back quickly, a disc 216 is fixedly connected to the outside of the limiting rod 214, and a push plate 218 is slidably connected to the outside of the limiting rod 214. A second spring 215 is fixedly connected between the push plate 218 and the disc 216. Thus, when the connecting plate 203 is pushed, the push plate 218 will be squeezed by the connecting plate 203. At this time, the second spring 215 will be squeezed by the push plate 218. When the connecting plate 203 is no longer pushed, the second spring 215 will bounce the connecting plate 203 back quickly by bouncing the push plate 218 back.
[0024] When the half gear 213 is pushed, the half gear 213 will push the swing plate 212 to swing around the movable shaft 219. At this time, one side of the swing plate 212 will push the fixed column 211 to move. The displacement of the fixed column 211 will push the connecting plate 203 to move. The displacement of the connecting plate 203 will push the slider 206 to move. The displacement of the slider 206 will push the pulley 209 to move laterally by pushing the central shaft 210. The displacement of the pulley 209 will push the protrusion 202 to move longitudinally. The displacement of the protrusion 202 will push the support plate 204 to move longitudinally by pushing the placement frame 205. The displacement of the support plate 204 will push the support leg 7 to move longitudinally by pushing the mounting frame 6. At this time, the support leg 7 will contact the ground and replace the universal wheel 5 to support the device. Thus, the body 1 can be stably supported by the support leg 7.
[0025] Please see Figure 3 and Figure 7 The drive assembly 3 includes a support base 303, which is disposed on one side of the fixed plate 201. A rotary motor 301 is disposed on one side of the support base 303. The rotary motor 301 is a bidirectional motor, and its output end can rotate forward or backward. A threaded tube 304 is keyed to the output end of the rotary motor 301. A sleeve 306 is screwed onto the outside of the threaded tube 304. A movable plate 305 is disposed on one side of the sleeve 306. Two sets of racks 302 are disposed on one side of the movable plate 305, and the racks 302 mesh with the half gears 213. After the rotary motor 301 is turned on, the output end of the rotary motor 301 will drive the threaded tube 304 to rotate. The rotation of the threaded tube 304 will drive the sleeve 306 to move linearly. The displacement of the sleeve 306 will push the movable plate 305 to move. The displacement of the movable plate 305 will push the racks 302 to move. The displacement of the racks 302 will push the half gears 213 to rotate.
[0026] This mobile energy storage battery device, through the cooperation between the pulley 209 and the protrusion 202, will push the support plate 204 to move longitudinally by pushing the protrusion 202 to move longitudinally when the pulley 209 moves laterally. The displacement of the support plate 204 will push the support leg 7 to move longitudinally by pushing the mounting bracket 6. At this time, the support leg 7 will contact the ground and replace the caster 5 to support the device. This avoids the situation where the caster 5 adopts an arc-shaped contact surface design, which makes the device prone to displacement.
[0027] In use, turning on the rotary motor 301 causes its output end to drive the threaded tube 304 to rotate. The rotation of the threaded tube 304 will cause the sleeve 306 to move linearly. The displacement of the sleeve 306 will push the moving plate 305 to move. The displacement of the moving plate 305 will push the rack 302 to move. The displacement of the rack 302 will push the half gear 213 to rotate. When the half gear 213 is pushed, it will push the swing plate 212 to swing around the movable shaft 219. At this time, one side of the swing plate 212 will push the fixed column 211 to move. The displacement of the fixed column 211 will push the connecting... When the connecting plate 203 moves, the displacement of the connecting plate 203 will push the slider 206 to move. The displacement of the slider 206 will push the pulley 209 to move laterally by pushing the central shaft 210. The displacement of the pulley 209 will push the protrusion 202 to move longitudinally. The displacement of the protrusion 202 will push the support plate 204 to move longitudinally by pushing the placement frame 205. The displacement of the support plate 204 will push the support leg 7 to move longitudinally by pushing the mounting frame 6. At this time, the support leg 7 will contact the ground and replace the universal wheel 5 to support the device. Thus, the body 1 can be stably supported by the support leg 7.
