Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a wheel-shaped energy storage compartment, including an energy storage compartment body 1. Foldable multi-directional drive components 2 are located at the four corners of the bottom surface of the energy storage compartment body 1. Each foldable multi-directional drive component 2 includes a mounting base 201, which is detachably connected to the bottom surface of the energy storage compartment body 1 by fasteners. An upper connecting shaft 202 and a lower connecting shaft 203 are coaxially arranged and rotatably connected below the mounting base 201. The upper connecting shaft 202 and the lower connecting shaft 203 are rotatably connected at opposite ends by a hinge structure. A first connecting member 206 is integrally provided at the bottom end of the lower connecting shaft 203. The first connecting member 206 has a ring structure and one end of a rotating shaft 207 is rotatably mounted inside it. A moving wheel 3 is fixedly connected to the other end of the rotating shaft 207. A folding mechanism is provided between the upper connecting shaft 202 and the lower connecting shaft 203, and a drive mechanism is provided on the lower connecting shaft 203.

[0023] Please see Figure 2 and Figure 3 The hinge structure includes a hinge seat 204 integrally mounted on the upper connecting shaft 202 and a hinge plate 205 integrally mounted on the lower connecting shaft 203. The hinge plate 205 is rotatably connected in the hinge seat 204.

[0024] The hinge seat 204 is a grooved structure with ear plates on both sides. The hinge plate 205 is inserted into the groove and rotatably connected to the ear plates via a pin, forming a stable rotating pair. This ensures that the upper connecting shaft 202 and the lower connecting shaft 203 can smoothly rotate relative to each other around the pin under the drive of the folding mechanism, providing reliable support for folding angles from 0° to 180°. The hinge structure has low rotational resistance and high stability, and can withstand the weight pressure of the energy storage compartment for a long time without easily being damaged, effectively ensuring the long-term reliable operation of the folding function.

[0025] Furthermore, the hinge seat 204 and the hinge plate 205 are respectively disposed on the outer wall of one side of the upper connecting shaft 202 and the lower connecting shaft 203, and the hinge plate 205 has an L-shaped structure.

[0026] Both the hinge seat 204 and the hinge plate 205 are offset from the axes of the upper connecting shaft 202 and the lower connecting shaft 203 to avoid structural interference caused by the coincidence of their axes during folding. When the L-shaped hinge plate 205 is folded to 0°, its lateral portion can naturally fit against the outer wall of the upper connecting shaft 202, which reduces the overall volume after folding and prevents structural damage due to over-folding through the limiting effect of the fitting surface. While ensuring the folding function, space is maximized so that the foldable multi-directional drive assembly 2 can be more compactly stored at the bottom of the energy storage compartment body 1 without occupying additional external space.

[0027] Furthermore, the top end of the upper connecting shaft 202 is rotatably connected to the bottom surface of the mounting base 201. The top surface of the mounting base 201 has a recessed mounting cavity, in which a directional drive motor 208 is fixedly installed. One end of the output shaft of the directional drive motor 208 is fixedly connected to the top end of the upper connecting shaft 202 through a through hole.

[0028] The direction drive motor 208 starts after receiving a control signal (such as a wireless remote control or control panel command), and drives the upper connecting shaft 202 to rotate relative to the mounting base 201 via its output shaft. Since the upper connecting shaft 202, lower connecting shaft 203, and moving wheel 3 are linked, the rotation of the upper connecting shaft 202 will cause the lower connecting shaft 203 and moving wheel 3 to rotate as a whole, thus adjusting the direction of movement. The mounting cavity provides protection for the direction drive motor 208, preventing external dust and rainwater from directly contacting the motor. At the same time, the direct connection between the motor and the upper connecting shaft 202 reduces power transmission loss, making direction adjustment more precise and response faster, meeting the needs of complex movement scenarios such as turning in narrow passages and rotating in place.

[0029] Furthermore, a first mounting plate 209 is integrally provided on the outer wall of the upper connecting shaft 202 away from the hinge structure. A telescopic drive device 210 is rotatably mounted on one side surface of the first mounting plate 209 via a rotating shaft. An L-shaped connecting plate 211 is integrally provided on the outer wall of the lower connecting shaft 203. A connecting rod 212 is fixedly mounted on one side surface of the L-shaped connecting plate 211. A second connecting member 213 is integrally provided at one end of the piston rod of the telescopic drive device 210. The second connecting member 213 has a ring structure and is rotatably sleeved on the outside of the connecting rod 212.

[0030] The telescopic drive device 210 (such as an electric push rod) is rotatably mounted on the first mounting plate 209 via a rotating shaft. The second connecting piece 213 at one end of its piston rod is rotatably sleeved on the connecting rod 212 of the L-shaped connecting plate 211. This double-rotation connection method avoids rigid stress caused by angle changes during the drive process. When expansion is required, the piston rod of the telescopic drive device 210 extends, pushing the L-shaped connecting plate 211 to rotate the lower connecting shaft 203 around the hinge structure, causing the upper connecting shaft 202 and the lower connecting shaft 203 to expand to 180°, perpendicular to the bottom of the energy storage compartment body 1. When folding is required, the piston rod retracts, pulling the lower connecting shaft 203 to rotate in the opposite direction until it is folded to 0°. The folding function is achieved through telescopic movement, resulting in stable operation and low energy consumption. Simultaneously, the rotating connection design extends the service life of the device.

[0031] Furthermore, a second mounting plate 214 is integrally provided on the outer wall of the lower connecting shaft 203 away from the hinge structure. A power drive motor 215 is fixedly mounted on one side surface of the second mounting plate 214. A drive bevel gear 216 is fixedly sleeved on one end of the output shaft of the power drive motor 215. The drive bevel gear 216 meshes with the driven bevel gear 217. The driven bevel gear 217 is fixedly sleeved on the rotating shaft 207.

[0032] After the drive motor 215 starts, the driving bevel gear 216 rotates with the output shaft, meshing with the driven bevel gear 217 and the rotating shaft 207 to rotate, ultimately driving the moving wheel 3 to move the energy storage compartment. The bevel gear enables vertical power transmission, allowing the drive motor 215 to be mounted axially along the lower connecting shaft 203, avoiding obstruction of the radial space of the moving wheel 3. Simultaneously, the high stability of the meshing transmission ensures efficient power transmission. Furthermore, by indirectly connecting the motor and the moving wheel 3 via gears, the gear ratio can be adjusted to adapt to different movement speed requirements, meeting the energy storage compartment's movement efficiency requirements in various scenarios.

[0033] Furthermore, a leakage protection device 218 is installed on the outer wall of one side of the mounting base 201.

[0034] The leakage current protection device 218 integrates components such as a current sensor and an electromagnetic switch. The current sensor is connected to the circuit system of the energy storage compartment body 1 and related electrical components of the moving wheels 3 via wires, monitoring the leakage current in the circuit in real time. When the detected leakage current reaches a dangerous threshold, the electromagnetic switch immediately cuts off the electrical connection between the energy storage compartment body 1 and the moving wheels 3, preventing the current from being conducted to the person who comes into contact with it through the moving wheels 3. At the same time, the outer shell of the leakage current protection device 218 is connected to the metal shell of the energy storage compartment body 1 through a highly conductive copper braided strip. The metal shell is then connected to the earth through a grounding stake, forming an equipotential grounding system. Even if the leakage current protection device 218 fails to disconnect the power in time, the current will still be conducted to the earth through the grounding system, preventing the person who comes into contact with it from being electrocuted. In addition, the leakage current protection device 218 is linked with the drive mechanism of the foldable multi-directional drive assembly 2. When the power is cut off, a signal is sent synchronously to stop the drive mechanism from working, preventing the energy storage compartment from continuing to move and increasing the risk while in a leakage state. Through multiple protection mechanisms, the problem of traditional energy storage compartments lacking protection against accidental electric shock is solved, improving the safety of use.

[0035] Please see Figure 4 Each movable wheel 3 includes a wheel rim 301. Inside the wheel rim 301, a connecting part 302 is coaxially arranged and fixedly connected to the rotating shaft 207. The outer wall of the connecting part 302 and the inner wall of the wheel rim 301 are integrally formed with several ring-shaped and evenly distributed support parts. The outer wall of the wheel rim 301 is provided with a shock-absorbing and anti-slip layer.

[0036] The wheel rim 301 is made of high-strength, low-weight material to ensure it can withstand the weight of the energy storage compartment. The shock-absorbing and anti-slip layer on the outer wall is made of flame-retardant rubber, which can both cushion the impact of ground bumps on the energy storage compartment through its own elasticity and increase the friction with the ground to prevent slippage during movement. The support part evenly transmits the force of the connecting part 302 to the wheel rim 301, preventing the wheel rim 301 from deforming due to excessive local stress. The overall structure takes into account both load-bearing capacity and mobility stability, adapting to the mobility needs of complex terrains (such as slopes and gravel roads).

[0037] Furthermore, each support part is a Y-shaped structure consisting of an integrally formed main support section 303 and two branch support sections 304. One end of the main support section 303 is connected to the outer wall of the connecting part 302, and the other end of the main support section 303 is connected to one end of the two branch support sections 304. The other ends of the two branch support sections 304 are connected to the inner wall of the wheel rim 301. Both branch support sections 304 are provided with bending angles on both sides of the corresponding main support section 303.

[0038] One end of the main support section 303 is connected to the outer wall of the connecting part 302, and the other end branches into two branch support sections 304, which are connected to the inner wall of the wheel rim 301. The two branch support sections 304 are bent at a certain angle towards both sides of the main support section 303, forming a triangular stable structure. The main support section 303 mainly bears the vertical load, distributing the weight of the energy storage compartment transmitted from the connecting part 302 to the two branch support sections 304. The two branch support sections 304 form lateral support through the bending angle, resisting the lateral force generated when the moving wheel 3 turns or moves laterally, and preventing damage to the wheel rim 301 and the connecting part 302 due to excessive lateral force. Compared with the traditional straight support structure, the Y-shaped structure achieves the same or even higher strength with less material, reducing the weight of the moving wheel 3 while improving the load-bearing and deformation resistance, which meets the design requirements of the energy storage compartment for material saving and economic reliability.

[0039] Working principle: The energy storage compartment body 1 achieves flexible movement and safety protection through the foldable multi-directional drive components 2 at the four corners of the bottom. The mounting base 201 fixes the components to the bottom of the energy storage compartment body 1. The upper connecting shaft 202 and the lower connecting shaft 203 are rotatably connected by a hinge structure. The folding mechanism drives the two to fold from 0° to 180°. The directional drive motor 208 drives the upper connecting shaft 202 and the lower connecting shaft 203 to rotate as a whole. In conjunction with the drive mechanism, the rotating shaft 207 and the moving wheel 3 rotate. The moving wheel 3 achieves high-strength load-bearing and movement through the Y-shaped connection part, achieving omnidirectional flexible movement. At the same time, the leakage protection device 218 on the mounting base 201 prevents electric shock by detecting current, automatically cutting off power, and equipotentially grounding with the metal shell of the energy storage compartment (internal wiring of the support shaft). Combined with the insulating material of the moving wheel 3, this ensures efficient movement, safety protection, and stable operation of the energy storage compartment.

[0040] It should be noted that the specific models and specifications of the energy storage compartment body 1, the directional drive motor 208, the telescopic drive device 210, the power drive motor 215, and the leakage protection device 218 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0041] The power supply and operating principle of the energy storage compartment body 1, the directional drive motor 208, the telescopic drive device 210, the power drive motor 215, and the leakage protection device 218 are clear to those skilled in the art and will not be described in detail here.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
