Description

Technical Field

[0001] This utility model relates to the field of power supply, specifically to a portable vehicle-mounted emergency power supply. Background Technology

[0002] As the name suggests, a vehicle emergency power supply is a device that provides power support to vehicles and related equipment in emergency situations. When the battery of a car or other vehicle is depleted and cannot work properly, the vehicle emergency power supply can serve as a backup power source, providing the necessary voltage to the vehicle's starting system, ensuring that the vehicle can start normally and get out of trouble.

[0003] Existing vehicle emergency power supplies still have some problems when used: When using a vehicle emergency power supply, the emergency jump starter harness needs to be connected to the car battery. The harness is long and may become loose, which makes it inconvenient to use the emergency power supply and also makes it inconvenient to carry the power supply.

[0004] Therefore, it is necessary to invent a portable vehicle-mounted emergency power supply to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a portable vehicle emergency power supply to solve the problem mentioned in the background art that the vehicle emergency power supply requires the emergency starter harness to be connected to the car battery when in use. The long power harness may cause the power cord to become loose, which makes it inconvenient to use the emergency power supply and also makes it inconvenient to carry the power supply.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable vehicle-mounted emergency power supply, comprising a charging module body, the charging module body being connected to a connecting wire, and a take-up reel being fitted around the outside of the connecting wire, and a take-up cavity being provided inside the take-up reel, with the connecting wire wound inside the take-up cavity, and a first wire-passing hole being provided inside the take-up reel, through which the connecting wire passes; a winding post being rotatably installed inside the take-up cavity, and a second wire-passing hole being provided inside the winding post, wherein the connecting wire is fixedly connected to the inner wall of the second wire-passing hole, and the winding post is rotated and fixed inside the take-up reel by a toggle assembly.

[0007] Preferably, the winding cavity is cylindrical and connected to the wire threading hole. The top and bottom walls of the winding cavity are attached to the outer wall of the connecting wire and are movably connected, which facilitates winding the connecting wire into the winding cavity and ensures that the connecting wire does not become tangled after winding.

[0008] Preferably, the actuating component includes a movable groove preset inside the winding post, and a linkage rod is movably connected inside the movable groove via a spring. A protrusion is fixedly connected to the outer wall of the linkage rod, and an actuating block is fixedly connected to the top of the linkage rod. Actuating the actuating block drives the winding post to rotate, thereby achieving the winding and storage of the connecting wire.

[0009] Preferably, the actuating block consists of a circular plate and four extended square plates fixedly connected to the outer wall of the circular plate. The four extended square plates are distributed in a ring at equal angles. The actuating block matches the matching groove reserved on the top of the winding reel. After the actuating block matches the matching groove, the angle of the winding column is limited, so that the connecting wires wound on the outer ring of the winding column will not be loosened after being stored.

[0010] Preferably, the movable groove consists of a columnar groove and a vertical groove connected to the columnar groove. The columnar groove is attached to the outer wall of the linkage rod to achieve a sliding connection between the upper and lower parts. The inner wall of the vertical groove is attached to the outer wall of the protrusion to achieve a sliding connection between the upper and lower parts. Both the upper and lower ends of the vertical groove are closed to ensure that the rotation of the linkage rod after it moves up and down can still drive the rotation of the winding column to achieve the winding of the connecting wire.

[0011] Preferably, the upper end of the spring is fixedly connected to the lower end of the linkage rod, and the lower end of the spring is fixedly connected to the bottom wall of the movable groove.

[0012] Preferably, the matching groove is connected to the notch, and there are four notches. The four notches are connected to the slots in the matching grooves of the extended square plate in the toggle block, so as to facilitate the unlocking and rotation of the linkage rod by pushing the toggle block upward through the notch.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] This invention unlocks the linkage rod by pushing the push block upwards through the notch. The rotation of the push block causes the winding column to rotate, which in turn causes the connecting wire to be wound and stored on the outer ring of the winding column. This facilitates the organization of the connecting wire. At the same time, the push block matches the matching slot to limit the angle of the winding column, thus preventing the connecting wire wound on the outer ring of the winding column from coming loose. This ensures that the connecting wire does not affect the subsequent use of the power supply, making the emergency power supply composed of the connecting wire and the charging module more portable.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-4 The portable vehicle-mounted emergency power supply shown includes a charging module body 1, which is connected to a connecting wire 2. A winding reel 3 is installed on the outside of the connecting wire 2, and a winding cavity 4 is provided inside the winding reel 3. The connecting wire 2 is wound inside the winding cavity 4. A first wire-passing hole 5 is provided inside the winding reel 3, through which the connecting wire 2 passes. A winding post 6 is rotatably installed inside the winding cavity 4, and a second wire-passing hole 7 is provided inside the winding post 6. The connecting wire 2 is fixedly connected to the inner wall of the second wire-passing hole 7. The winding post 6 is rotated and fixed inside the winding reel 3 by a toggle component 8.

[0024] During use, the linkage rod 802 is unlocked by pushing the toggle block 801 upward through the notch 807. The rotation of the toggle block 801 causes the winding post 6 to rotate, which in turn causes the connecting wire 2 to be wound and stored on the outer ring of the winding post 6. This makes it easy to organize the connecting wire 2. At the same time, after the toggle block 801 matches the matching slot 806, the angle of the winding post 6 is limited, so that the connecting wire 2 wound on the outer ring of the winding post 6 will not come loose after being stored. This makes the emergency power supply composed of the connecting wire 2 and the charging module body 1 connected to the connecting wire 2 more portable and easier to use.

[0025] To facilitate the storage of the connecting wire 2, the winding cavity 4 is cylindrical and connected to the wire hole 5. The top and bottom walls of the winding cavity 4 are attached to the outer wall of the connecting wire 2 and are movably connected, making it easy to wind and rewind the connecting wire 2 into the winding cavity 4. This ensures that the connecting wire 2 is not tangled after being wound up, making the emergency power supply composed of the connecting wire 2 and the charging module body 1 more portable.

[0026] The actuating component 8 includes a movable groove 804 pre-set inside the winding post 6, and a linkage rod 802 is movably connected inside the movable groove 804 via a spring 805. A protrusion 803 is fixedly connected to the outer wall of the linkage rod 802, and an actuating block 801 is fixedly connected to the top of the linkage rod 802. The upper end of the spring 805 is fixedly connected to the lower end of the linkage rod 802, and the lower end of the spring 805 is fixedly connected to the bottom wall of the movable groove 804, which facilitates the up-and-down movement and reset movement of the linkage rod 802.

[0027] The actuating block 801 consists of a circular plate and four extended square plates fixedly connected to the outer wall of the circular plate. The four extended square plates are distributed in a ring at equal angles, and the actuating block 801 matches the matching groove 806 reserved on the top of the take-up reel 3.

[0028] When the actuating block 801 matches the matching slot 806, the angle of the winding post 6 is limited. Under the action of the spring 805, the linkage rod 802 drives the actuating block 801 to match the matching slot 806 completely, so that the connecting wire 2 wound on the outer ring of the winding post 6 will not come loose after being stored.

[0029] The movable groove 804 consists of a columnar groove and a vertical groove connected to the columnar groove. The columnar groove is attached to the outer wall of the linkage rod 802 to achieve a sliding connection between the upper and lower parts. The inner wall of the vertical groove is attached to the outer wall of the protrusion 803 to achieve a sliding connection between the upper and lower parts. Both the upper and lower ends of the vertical groove are closed. The matching groove 806 is connected to the notch 807. There are four notches 807. The four notches 807 are connected to the slots in the matching groove 806 that are adapted to the extended square plate in the toggle block 801.

[0030] The linkage rod 802 can be unlocked and rotated by pushing the toggle block 801 upward through the notch 807. The rotation of the linkage rod 802 drives the rotation of the winding column 6 to store and organize the connecting wire 2, making the emergency power supply composed of the connecting wire 2 and the charging module body 1 more portable.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
