Description

Technical Field

[0001] This utility model relates to the field of storage batteries, and in particular to a storage battery that is easy to move. Background Technology

[0002] Batteries are widely used as a power source in many industries, resulting in high utilization rates. However, this also presents challenges in the bulk management of batteries. For medium-sized batteries, such as those used in electric vehicles, manual loading and unloading requires workers to first load and arrange the batteries on the vehicle. To save time and effort, the batteries are often moved and organized immediately after loading. Due to the weight of the batteries, the friction from the ground is significant when moving them, which can lead to difficulties such as difficulty in moving large quantities of batteries, making it hard to place them easily. Moreover, this method of handling is time-consuming and inefficient.

[0003] Utility model CN210503698U discloses a lead-acid battery that facilitates mobile transportation. It includes a casing, a snap-fit ​​structure fixedly installed at the bottom of the casing, and plug-in structures inserted into both sides of the snap-fit ​​structure. A movable structure is fixedly installed on the snap-fit ​​structure via the plug-in structures. An auxiliary structure is fixedly installed on one side of the outer surface of the casing, and a battery is fixedly installed inside the casing. This utility model achieves convenient transportation and reduces the labor intensity of manual handling through its movable mechanism; however, its movement and steering are not flexible and it cannot adjust its direction of travel in a timely manner, leaving room for improvement. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a conveniently movable battery, solving the problem of inflexible battery movement and steering, thereby improving battery installation efficiency and significantly saving manpower. The technical solution of this application is as follows:

[0005] This utility model provides a portable storage battery, including an energy storage device, with a movable component connected to the bottom of the energy storage device. The movable component includes a roller and a mounting member, the mounting member being rotatably connected to the energy storage device, and the roller being connected to one side of the mounting member. The mounting member is provided with an adjusting member and a foot pad, one end of the adjusting member abutting against the mounting member, and the opposite end being connected to the foot pad. An adjusting opening is provided on the side of the mounting member, and the adjusting opening is located on one side of the adjusting member.

[0006] The mounting component has an outwardly extending extension on its side, with a connecting hole for mounting the roller via bolts. One end of the mounting component has an inwardly extending blind hole, forming a mounting groove with a small recess at the top. An adjusting component is located in the mounting groove, with one end abutting the small recess and the other end having external threads. A foot pad has a channel with threads, allowing it to connect threadedly to the adjusting component. The foot pad protrudes from the blind hole opening of the mounting component. Rotating the adjusting component adjusts the foot pad's height, raising the roller and converting the battery into a stationary position. An adjustment port is located on the side wall of the mounting groove, connecting it to the outside. Positioned to one side of the adjusting component, it allows the user to adjust the foot pad's height by rotating the adjusting component from outside the mounting component.

[0007] In a preferred embodiment of this invention, the mounting component has a limiting portion, and the foot pad is engaged with the limiting portion.

[0008] The limiting part is located on the side wall of the mounting groove, and the foot pad is correspondingly provided with a concave edge. The limiting part and the concave edge are engaged to restrict the rotation of the foot pad and prevent the foot pad from rotating synchronously when the adjustment part is rotated, thus failing to achieve the effect of adjusting the height.

[0009] In a preferred embodiment of this invention, the adjusting member includes a protrusion and a shaft, the shaft connects the mounting member and the foot pad, and the protrusion is circumferentially disposed on the shaft.

[0010] The adjusting component uses a shaft to abut against the mounting groove and is threaded to the foot pad. The protrusions distributed on the side of the shaft have multiple sides, making it easier for the adjusting component to bear force, which helps the user to turn the adjusting component and makes it easy to adjust.

[0011] In a preferred embodiment of this invention, the energy storage device is detachably connected to a base, and a steering component is fixed at the four corners of the bottom of the base. The steering component has a groove, and a ball bearing is rotatably connected in the groove. The mounting component is bolted to the steering component to clamp the ball bearing on the top surface of the mounting component.

[0012] The base and energy storage device are bolted together, and the steering component is attached to the base. The roller groove is annular, with its center coinciding with the center of the steering component. The balls are arranged along the annular groove, closely packed within it. The mounting component and steering component are bolted together, allowing the mounting component to rotate, and the mounting component and steering component hold the balls between them. When the roller contacts and rolls on the ground, the roller experiences friction from the ground, which is transmitted to the mounting component through the bolts. Due to the rotatability of the balls, the mounting component can rotate in the direction of the resistance experienced by the roller to reduce resistance, thereby achieving the steering of the roller.

[0013] In a preferred embodiment of this invention, a conductive port electrically connected to the energy storage device is further included, the conductive port being disposed on the energy storage device. The conductive port includes a conductive element, an interface element connected to the conductive element, and a fixing element; both the conductive element and the interface element are snapped onto the fixing element, the interface element penetrating the conductive element, and the conductive element penetrating the fixing element.

[0014] The conductive ports include a charging port and a discharging port, and the charging port and discharging port have the same structure. The fixing component is bolted to the outer casing of the energy storage device. The outer casing has conductive holes at the connection point, and the fixing component has corresponding conductive grooves. Additionally, the fixing component has grooves for mounting the interface component and the conductive component. The interface component is an electrode post; the larger end is snapped into the corresponding groove, and the smaller end can be electrically connected to the battery clamp. One end of the conductive component passes through the conductive groove into the interior of the energy storage device, and then connects to the energy storage unit via a wire. The other end connects to the interface component and is snapped onto the fixing component to achieve discharge.

[0015] In a preferred embodiment of this invention, the fixing member is covered with a cover that engages with the fixing member, and one end of the interface member penetrates through the top of the cover.

[0016] The enclosure is placed over the fixing and conductive components, and the bottom cavity wall surrounds the fixing, conductive, and interface components. This reduces the probability of leakage caused by contact between the interface components and conductive components and other conductive materials, and protects other components below, such as the fixing components, from damage. Moreover, one end of the interface component passes through the enclosure and protrudes from the top of the enclosure, allowing the port to be connected to the electrical appliance without removing the enclosure, which is convenient and quick.

[0017] In a preferred embodiment of this invention, an insulating cap is fitted onto one end of the interface component that penetrates the cover.

[0018] An insulating cap is snapped onto one end of the interface component, isolating the interface component from other conductive materials when not in use, thereby improving the electrical safety of the battery.

[0019] In a preferred embodiment of this invention, the top of the cover is provided with a connecting groove through which the interface component passes.

[0020] The connection slot provides a connection point to help users quickly locate and connect the battery when charging and discharging it. After connection, it can restrict the movement of the connector, thus preventing the connector from becoming loose.

[0021] In a preferred embodiment of this invention, two connection ports are provided on the side of the cover, and the two connection ports are symmetrically arranged on both sides of the cover.

[0022] A baffle is installed at the connection port to reduce the probability of liquid splashing and contact with the interface component. The design of the connection port allows the interface component to connect to the chuck while it is covered by the cover, thereby improving the safety of the connection. At the same time, the cover provides a limit for the chuck, increasing the stability of the connection.

[0023] The specific implementation process of this device is as follows: When the battery is placed face down, the roller contacts the ground. Pushing the battery causes the roller to roll, moving the battery and facilitating its movement. When the battery needs to be stored for an extended period, the foot pads can be extended beyond the mounting bracket by rotating the adjustment mechanism, thereby raising the rollers and making the battery less prone to movement, ensuring safe storage. When using the battery, the clamp can be inserted into the interface under the cover through the connection port, or the insulating cap can be removed and the connector aligned with the connection slot on the cover to connect to the interface for current supply.

[0024] The beneficial effects of this utility model include at least the following:

[0025] This utility model provides a portable storage battery. The storage battery has a movable component connected to the bottom of the energy storage device. The movable component achieves the effect of movement by means of rollers. The direction of the rollers is changed in time according to the resistance encountered when the rollers rotate, so that the storage battery can be moved flexibly in multiple directions, improving its practicality.

[0042] Example 1

[0043] See Figures 1 to 3 As shown, this application provides a portable storage battery, including an energy storage device 1. A movable component 3 is fixedly connected to the bottom of the energy storage device 1. The movable component 3 includes a roller 31 and a mounting component 32. The mounting component 32 is rotatably connected to the energy storage device 1, and the roller 31 is rotatably connected to one side of the mounting component 32. An adjusting component 33 and a foot pad 4 are provided in the mounting component 32. One end of the adjusting component 33 abuts against the mounting component 32, and the other end is threadedly connected to the foot pad 4. An adjusting port 322 is opened on the side of the mounting component 32, and the adjusting port 322 is located on one side of the adjusting component 33.

[0044] Specifically, the mounting component 32 has a cylindrical structure with two outwardly extending extensions on its side. These extensions have connecting holes, allowing the roller 31 to be mounted on the mounting component 32 by bolts passing through the connecting holes and centering with the roller 31. One end of the mounting component 32 has an inwardly formed blind hole, creating a mounting groove with a small recess at the top. The adjusting component 33 is a disc-shaped piece with support rods at both ends, integrally positioned within the mounting groove. One end abuts against the small recess, and the other end has external threads. The foot pad 4 has a channel with threads on its sidewalls, allowing it to be threadedly connected to the adjusting component 33. The foot pad 4 protrudes from the blind hole opening of the mounting component 32. Rotating the adjusting component 33 adjusts the height of the foot pad 4, thus elevating the roller 31 and converting the battery into a non-moving placement method. The adjustment port 322 is opened on the side wall of the mounting slot, connecting the mounting slot to the outside. Its position is on one side of the adjustment component 33, so that the user can rotate the adjustment component 33 in the mounting slot from the outside of the mounting component 32 to adjust the height of the foot pad 4.

[0045] Furthermore, the mounting component 32 has a limiting part 321, and the foot pad 4 is engaged with the limiting part 321.

[0046] Specifically, the limiting part 321 is a raised strip, which is vertically and symmetrically arranged on the side wall of the mounting groove. The foot pad 4 is provided with a corresponding concave edge. The limiting part 321 and the concave edge are engaged to restrict the rotation of the foot pad 4, which replaces the original method of adjusting the height by friction between the foot pad 4 and the mounting part 32. This avoids the foot pad 4 and the adjusting part 33 rotating synchronously and failing to achieve the effect of adjusting the height.

[0047] Furthermore, the adjusting member 33 includes a protrusion 331 and a shaft 332, the shaft 332 is connected to the mounting member 32 and the foot pad 4, and the protrusion 331 is circumferentially arranged on the shaft 332.

[0048] Specifically, one end of the adjusting member 33 abuts against the mounting groove via the shaft 332, and the other end is threaded to the foot pad 4. The protrusions 331 distributed on the side of the shaft 332 have multiple sides and edges, making it easier for the user to apply force when turning it, which helps the user to use the adjusting member 33 and makes it easier to adjust.

[0050] See Figures 1 to 5As shown, this embodiment provides a portable battery, including an energy storage device 1. A movable component 3 is fixedly connected to the bottom of the energy storage device 1. The movable component 3 includes a roller 31 and a mounting component 32.

[0051] Specifically, the mounting component 32 has a cylindrical structure with two outwardly extending extensions on its side. These extensions have connecting holes, allowing the roller 31 to be mounted on the mounting component 32 by bolts passing through the connecting holes and centering with the roller 31. One end of the mounting component 32 has an inwardly formed blind hole, creating a mounting groove with a small recess at the top. The adjusting component 33 is a disc-shaped piece with support rods at both ends, integrally positioned within the mounting groove. One end abuts against the small recess, and the other end has external threads. The foot pad 4 has a channel with threads on its sidewalls, allowing it to be threadedly connected to the adjusting component 33. The foot pad 4 protrudes from the blind hole opening of the mounting component 32. Rotating the adjusting component 33 adjusts the height of the foot pad 4, thus elevating the roller 31 and converting the battery into a non-moving placement method. The adjustment port 322 is opened on the side wall of the mounting slot, connecting the mounting slot to the outside. Its position is on one side of the adjustment component 33, so that the user can rotate the adjustment component 33 in the mounting slot from the outside of the mounting component 32 to adjust the height of the foot pad 4.

[0052] Furthermore, the mounting component 32 has a limiting part 321, and the foot pad 4 is engaged with the limiting part 321.

[0053] Specifically, the limiting part 321 is a raised strip, which is vertically and symmetrically arranged on the side wall of the mounting groove. The foot pad 4 is provided with a corresponding concave edge. The limiting part 321 and the concave edge are engaged to restrict the rotation of the foot pad 4, which replaces the original method of adjusting the height by friction between the foot pad 4 and the mounting part 32. This avoids the foot pad 4 and the adjusting part 33 rotating synchronously and failing to achieve the effect of adjusting the height.

[0054] Furthermore, the adjusting member 33 includes a protrusion 331 and a shaft 332, the shaft 332 is connected to the mounting member 32 and the foot pad 4, and the protrusion 331 is circumferentially arranged on the shaft 332.

[0055] Specifically, one end of the adjusting member 33 abuts against the mounting groove via the shaft 332, and the other end is threaded to the foot pad 4. The protrusions 331 distributed on the side of the shaft 332 have multiple sides and edges, making it easier for the user to apply force when turning it, which helps the user to use the adjusting member 33 and makes it easier to adjust.

[0056] Furthermore, it also includes a conductive port 2 electrically connected to the energy storage device 1. The conductive port 2 is disposed on the energy storage device 1. The conductive port 2 includes a conductive element 21, an interface element 22 connected to the conductive element 21, and a fixing element 23. The conductive element 21 and the interface element 22 are both snapped onto the fixing element 23. The interface element 22 passes through the conductive element 21, and the conductive element 21 passes through the fixing element 23.

[0057] Specifically, the conductive port 2 includes a charging port and a discharging port, and the charging port and discharging port have the same structure. The four corners of the fixing member 23 are bolted to the outer casing of the energy storage device 1. The outer casing has conductive holes at the connection points, and the fixing member 23 is correspondingly provided with conductive grooves, which are inserted into the conductive holes. In addition, the fixing member 23 is also provided with slots for installing the interface member 22 and the conductive member 21. The interface member 22 is an electrode post; the larger end is snapped into the corresponding slot, and the smaller end can be electrically connected to the battery clamp. The conductive member 21 has an L-shaped structure, one section of which has a through hole for the interface member 22 and a bent portion inserted into the groove of the fixing member 23.

[0058] Furthermore, the fastener 23 is covered with a cover 7 that engages with the fastener 23, and one end of the interface piece 22 penetrates through the top of the cover 7.

[0059] Specifically, the cover 7 is fitted over the fixing member 23, the conductive member 21, and the interface member 22. The edge of the side wall of the cover 7 abuts against the perimeter of the fixing member 23, and the size enclosed by the side wall is the same as that of the fixing member 23, so the cover 7 can be snapped onto the fixing member 23. The side wall of the cover 7 surrounds the fixing member 23, the conductive member 21, and the interface member 22, which on the one hand reduces the probability of leakage caused by the interface member 22 and other components coming into contact with other conductive materials, avoiding safety hazards; on the other hand, it protects other components underneath, such as the interface member 22, from collisions with other objects that could cause it to tilt. Moreover, one end of the interface member 22 passes through the cover 7 and protrudes from its top surface, allowing the interface member 22 to be connected to the connector without disassembling the cover 7, which is convenient and quick.

[0061] Specifically, the insulating cap 8 is nut-shaped and made of rubber or plastic, making it easy to twist and remove. Its inner edge size is the same as that of one end of the interface piece 22, and it is snapped onto one end of the interface piece 22, so that the interface piece 22 is isolated from other conductive materials when not in use, thereby improving the safety of the battery.

[0062] Furthermore, the top of the cover 7 is provided with a connecting groove 71 through which the interface component 22 passes.

[0063] Specifically, the connection slot 71 provides a connection position to help the user quickly locate and connect the battery when charging and discharging it, and after connection, it can restrict the movement of the connector, thus making it less likely to loosen.

[0064] Furthermore, two connection ports 72 are also provided on the side of the cover 7, and the two connection ports 72 are symmetrically arranged on both sides of the cover 7.

[0065] Specifically, a baffle is provided at the connection port 72 to reduce the probability of liquid splashing and contacting the interface component 22. The design of the connection port 72 allows the interface component 22 to be connected to the clamp while it is covered by the cover 7, thereby improving the safety of the connection. At the same time, the cover 7 can provide a limit for the clamp, increasing the stability of the connection.

[0068] Mounting component 32 has a cylindrical structure with two outwardly extending extensions on its side. The extensions have connecting holes, allowing the roller 31 to be mounted on the mounting component 32 by bolts passing through the connecting holes and centering with the roller 31. One end of the mounting component 32 has an inwardly formed blind hole, creating a mounting groove with a small recess at the top. Adjusting component 33 is a disc-shaped piece with support rods at both ends, integrally set in the mounting groove. One end abuts against the small recess, and the other end has external threads. Foot pad 4 has a channel with threads on its sidewalls, allowing it to be threadedly connected to adjusting component 33. Foot pad 4 protrudes from the blind hole opening of mounting component 32. Rotating adjusting component 33 adjusts the height of foot pad 4, thus elevating the roller 31 and converting the battery into a non-moving placement method. The adjustment port 322 is opened on the side wall of the mounting slot, connecting the mounting slot to the outside. Its position is on one side of the adjustment component 33, so that the user can rotate the adjustment component 33 in the mounting slot from the outside of the mounting component 32 to adjust the height of the foot pad 4.

[0069] Furthermore, the mounting component 32 has a limiting part 321, and the foot pad 4 is engaged with the limiting part 321.

[0070] Specifically, the limiting part 321 is a raised strip, which is vertically and symmetrically arranged on the side wall of the mounting groove. The foot pad 4 is provided with a corresponding concave edge. The limiting part 321 and the concave edge are engaged to restrict the rotation of the foot pad 4, which replaces the original method of adjusting the height by friction between the foot pad 4 and the mounting part 32.

When the roller 31 contacts and rolls on the ground, it experiences friction from the ground, which is then transmitted to the mounting component 32 via the bolts. Due to the rotatability of the balls 62, the mounting component 32 can adjust its rotation according to the direction of the resistance experienced by the roller 31 to reduce the resistance, thereby achieving steering of the roller 31. The base 5 can be used to install the moving component 3 and the steering component 6 as a whole, thus allowing the base 5 to be assembled separately from the energy storage device 1, reducing production time.
