Description

Technical Field

[0001] The utility model relates to the technical field of mobile power supplies, and particularly relates to an outdoor mobile power supply. Background Art

[0002] With the growth of the needs for outdoor activities and field operations, mobile power supplies, as independent power supply devices, are widely used in occasions without power supply such as urban power outages or outdoor powerless areas. Existing outdoor mobile power supplies are generally equipped with roller devices, and the device is moved by pulling the handlebar configured thereon.

[0003] The utility model with the authorized announcement number of CN216625351U discloses an outdoor mobile power supply, which relates to the technical field of power supplies. By providing a plurality of charging interfaces, a plurality of discharging interfaces, a sub-power supply and a wireless charging module, in actual use, the types of interfaces of the existing mobile power supply are increased, so that the whole mobile power supply can provide convenience for users with different needs, and further the practicability of the existing mobile power supply in outdoor use is improved. In addition, by providing a temperature sensor, an electric heater and a heat conducting plate, wherein the temperature sensor and the heat conducting plate are both arranged on the surface of the main power supply. When the temperature sensor monitors that the temperature in the mobile box is relatively low, the electric heater works to heat up the heat conducting plate, and under the action of heat conduction, the heat is transferred to the main power supply, thereby increasing the self-temperature of the main power supply, being not affected by the ambient temperature, and improving the charging and discharging efficiency of the main power supply.

[0004] The above-mentioned utility model is very inconvenient to use in complex terrain scenarios. When the fixed rollers of conventional products move on rough and uneven roads, the device is prone to rapid tilting and bumping changes due to the ground undulation, which is likely to cause the center of gravity of the device to shift and lead to rollover, and the severe vibration impacts the internal components of the battery, affecting the power supply quality of precision instruments. Summary of the Utility Model

[0005] To solve the above problems, the utility model provides an outdoor mobile power supply to solve the problem that the mobile power supply used outdoors is easily affected by rough roads and damages the internal components of the battery.

[0006] The utility model specifically adopts the following technical solutions to achieve the above object: An outdoor mobile power supply includes a battery box and a handlebar, and further includes moving wheels, support columns, a positioning and buffering mechanism and shock dampers. The handlebar is arranged on the front side of the battery box, and an adjusting mechanism is fixedly installed on the rear side of the battery box. A shock damper is fixedly installed at the mobile end inside the adjusting mechanism. The bottom end of the shock damper is fixedly connected to the top of the positioning and buffering mechanism, and the bottom of the positioning and buffering mechanism is connected to the top of the moving wheel. A limiting groove is opened at the bottom of the battery box, and the rotating end of the moving wheel is located inside the limiting groove of the battery box.

[0007] The battery box includes a box body, a box cover and a control panel. A power supply component is provided inside the box body. The box cover is hingedly installed on the top of the box body, and a control panel is provided inside the box body.

[0008] The moving wheels include rollers, rotating rods and sleeves. The number of rollers is two, and the two rollers are respectively fixedly installed at the left and right ends of the rotating rod. The rotating rod is rotatably installed inside the sleeve. Limiting bumps are provided at both ends of the rotating rod, and the rotating rod is fixedly connected to the bottom of the positioning and buffering mechanism.

[0009] The support column is rotatably installed at the bottom of the battery box. A torsion spring is provided at the connection between the support column and the battery box. The support column and the limiting groove of the battery box are arranged in correspondence.

[0010] The positioning and buffering mechanism includes a sliding sleeve, a sliding block, a sliding rod and a spring. An arc-shaped sliding groove is provided at the top of the sliding sleeve. The sliding block is slidably installed inside the arc-shaped sliding groove of the sliding sleeve. The sliding rod is fixedly installed inside the arc-shaped sliding groove of the sliding sleeve, and the sliding rod is slidably inserted into the sliding block. The number of springs is two, and the two springs are respectively fixedly installed inside the arc-shaped sliding groove of the sliding sleeve, and the free ends of the two springs are respectively connected to the left and right sides of the sliding block. The top of the sliding block is fixedly connected to the bottom of the shock damping, and the side of the sliding block is fixedly connected to the battery box.

[0011] The adjusting mechanism includes a support plate, a screw rod, a guide rod and a support block. The support plate is fixedly installed at the rear side of the battery box. The support block is slidably installed inside the support plate. The screw rod is rotatably installed inside the support plate. The screw rod is threadedly connected to the support block. The top end of the screw rod penetrates through the top of the support plate and is fixedly installed with a dial. The guide rod is fixedly installed inside the support plate, and the guide rod is slidably inserted into the support block.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In the present utility model, through the cooperation of the positioning and buffering mechanism and the moving wheels, the side of the sliding block is fixedly connected to the battery box, and the sliding block and the battery box remain stationary. Depending on the relative sliding between the sliding sleeve and the sliding block, when the staff holds the pull rod for handling, the moving wheels at the bottom of the positioning and buffering mechanism will displace with the left and right displacement of the sliding sleeve. The two springs can effectively ensure the reset of the sliding sleeve, and then the moving wheels are reset, thus ensuring the horizontal stability of the battery box during handling on the undulating road surface, thereby maintaining the stable movement of the device in the horizontal direction, reducing its inclination amplitude, and improving the safety of using the device outdoors;

[0014] Due to the undulation of the ground, the device shakes up and down. Through the shock damping, when handling the battery box, the shock damping performs shock absorption treatment on the vertical direction of the battery box, reducing the amplitude of the up and down shaking of the device, making the handling of the battery box more stable, reducing the vertical shaking degree during the handling of the battery box, reducing the impact force, and improving the safety of using the device outdoors;

[0015] The adjusting mechanism can effectively adjust the tightness of the shock damping. By rotating the dial, the screw rod rotates, thereby driving the support block to move up and down, so as to adjust the tightness of the shock damping to adapt to different road conditions. When the shock damping is adjusted to be tighter, the up-and-down shaking stroke of the battery box will become shorter. When the shock damping is adjusted to be looser, the up-and-down shaking stroke of the battery box will become longer, so as to cope with the handling work in different scenarios.

[0024] Figure 1-6 is the best embodiment of the present utility model. The following further describes the present utility model with reference to the attached Figure 1 - attached Figure 6 drawings.

[0025] An outdoor mobile power supply includes a battery box 1 and a pull rod 2, as well as moving wheels 3, a support column 4, a positioning and buffering mechanism 5, and a shock-absorbing damper 6. The front side of the battery box 1 is provided with a retractable pull rod 2, the rear side of the battery box 1 is fixedly mounted with an adjustment mechanism 7, and the movable end of the adjusting mechanism 7 is fixedly mounted with a shock-absorbing damper 6. The bottom end of the shock-absorbing damper 6 is fixedly connected to the top of the positioning and buffering mechanism 5, and the bottom of the positioning and buffering mechanism 5 is connected to the top of the moving wheel 3. A limiting groove is defined at the bottom of the battery box 1, and the rotating end of the moving wheel 3 is located within the limiting groove of the battery box 1.

[0026] Specifically, electric energy is stored in the battery box 1, thereby providing electric energy in outdoor areas without power supply. The battery box 1 is pulled by the pull rod 2 to facilitate the transportation of the device outdoors. The mobile wheel 3 supports the movement of the device. The support column 4 provides support for the parked device and limits the flipping of the mobile wheel 3. The positioning buffer mechanism 5 enables the mobile wheel 3 to slide horizontally left and right at its bottom, which has a buffering effect on the horizontal shaking of the mobile wheel 3, thereby reducing the horizontal shaking amplitude of the battery box 1. The vertical shaking of the device when moving is buffered by the shock absorber damper 6 to reduce the impact of drastic changes. The tightness of the shock absorber damper 6 is adjusted by the adjustment mechanism 7.

[0027] The battery box 1 includes a box body 101, a box cover 102 and a control panel 103. A power supply component is provided inside the box body 101. The power supply component is an existing energy storage lithium battery power supply, which belongs to the prior art and the specific structure is not repeated here. The box body 101 is hingedly mounted with the box cover 102 on the top. The box body 101 is provided with a control panel 103 inside. The control panel 103 is provided with ventilation holes, a display screen, control buttons, input and output jacks, and switches.

[0028] Specifically, the power supply components inside the box 101 store and output electrical energy, and the device is controlled and set through the control panel 103.

[0029] The moving wheel 3 includes a roller 301, a rotating rod 302 and a sleeve 303. There are two rollers 301, which are fixedly mounted on the left and right ends of the rotating rod 302 respectively. The rollers 301 are slidably mounted inside the limiting groove of the battery box 1. The rotating rod 302 is rotatably mounted inside the sleeve 303. The sleeve 303 is fixedly mounted on the bottom of the sliding sleeve 501. The two ends of the rotating rod 302 are provided with limiting protrusions, which are correspondingly arranged with the sliding sleeve 501. The rotating rod 302 is fixedly connected to the bottom of the positioning buffer mechanism 5.

[0030] Specifically, it moves by means of the roller 301 support device. The rotating rod 302 rotates inside the sleeve 303, enabling the roller 301 to flip, and it can be selected to be in the state within the limit groove of the battery box 1, or maintain the state where the limit bump of the rotating rod 302 is in close contact with the sliding sleeve 501, so as to adapt to the flat or rough ground conditions.

[0031] The support column 4 is rotatably installed at the bottom of the battery box 1. A torsion spring is provided at the connection between the support column 4 and the battery box 1. The support column 4 and the limit groove of the battery box 1 are arranged in correspondence.

[0032] Specifically, the torsion spring enables the support column 4 to remain in the state below the limit groove of the battery box 1 to block the roller 301 in the limit groove. When it is necessary to flip the roller 301, the support column 4 is pushed to rotate, thereby releasing its limit on the roller 301.

[0033] The positioning and buffering mechanism 5 includes a sliding sleeve 501, a sliding block 502, a sliding rod 503, and a spring 504. An arc-shaped chute is provided at the top of the sliding sleeve 501. The sliding block 502 is slidably installed inside the arc-shaped chute of the sliding sleeve 501. The sliding rod 503 is fixedly installed inside the arc-shaped chute of the sliding sleeve 501, and the sliding rod 503 is slidably inserted into the sliding block 502. The number of springs 504 is two. The two springs 504 are respectively fixedly installed inside the arc-shaped chute of the sliding sleeve 501, and the free ends of the two springs 504 are respectively connected to the left and right sides of the sliding block 502. The top of the sliding block 502 is fixedly connected to the bottom of the shock damping 6. The side of the sliding block 502 is fixedly connected to the battery box 1.

[0034] Specifically, the side of the sliding block 502 is fixedly connected to the battery box 1, and the sliding block 502 and the battery box 1 remain in a fixed state. Through the relative sliding of the sliding sleeve 501 and the sliding block 502, the roller 301 at the bottom of the sliding sleeve 501 can drive the sliding sleeve 501 to slide along with the undulation of the ground. The sliding rod 503 makes the sliding of the sliding block 502 more stable and prevents the spring 504 from disengaging from the inside of the arc-shaped chute of the sliding sleeve 501. Through the contact of the spring 504 with the sliding block 502 and the sliding sleeve 501, the deflected side can return to its original position.

[0035] The adjusting mechanism 7 includes a support plate 701, a screw rod 702, a guide rod 703, and a support block 704. The support plate 701 is fixedly installed at the rear side of the battery box 1. The support block 704 is slidably installed inside the support plate 701. The screw rod 702 is rotatably installed inside the support plate 701. The screw rod 702 is in threaded connection with the support block 704. The top end of the screw rod 702 penetrates through the top of the support plate 701 and is fixedly installed with a dial. The guide rod 703 is fixedly installed inside the support plate 701. The guide rod 703 is slidably inserted into the support block 704. The bottom of the support block 704 is fixedly connected to the top of the shock damping 6.

[0036] Specifically, by turning the dial of the screw 702, it drives the screw 702 to rotate, and the screw 702 drives the support block 704 to move up and down inside the support plate 701, thereby adjusting the tightness of the shock absorber 6, and the sliding of the support block 704 is guided by the guide rod 703 to make its movement process more stable.

[0037] In summary, when the present invention is in use, the staff opens the box cover 102, recharges the battery box 1 with electricity, closes the box cover 102, and pulls the pull rod 2 to unfold for outdoor activities, driving the battery box 1 to move. If the outdoor ground is in good condition and relatively flat, keep the roller 301 in the limit groove at the bottom of the battery box 1, rely on the support column 4 to limit the roller 301, and the staff pulls the pull rod 2 to drive the device to carry and move. If the outdoor ground is in poor condition and undulating, the support column 4 can be rotated to compress its torsion spring, flip the roller 301 to make the rotating rod 302 rotate inside the sleeve 303, push the roller 301 out of the limit groove of the battery box 1, loosen the support column 4 to return it to its original position, rotate the roller 301 until the limit protrusion of the rotating rod 302 fits with the bottom of the sliding sleeve 501, and the dial belt can be toggled according to the needs of transportation. The movable screw 702 rotates, and the support block 704 moves up and down under the guidance of the guide rod 703, so that the tightness of the shock absorber 6 can be adjusted according to different road conditions to cope with different road conditions, and at the same time, it can avoid collision with external objects during movement. In the process of pulling the pull rod 2 to move the battery box 1, the undulating ground causes the two rollers 301 to be at different heights. The side of the slider 502 is fixedly connected to the battery box 1 and remains stationary. The left and right tilt is maintained stable by the relative sliding of the sleeve 501 and the slider 502, and the two springs 504 drive the deflected sleeve 501 to return to its original position. The up and down shaking is absorbed and buffered by the shock absorber 6, which reduces the shaking amplitude and conversion speed at the battery box 1, improves the stability of the battery box 1, and ensures that the device maintains smooth movement on rugged roads.
