Description

Technical Field

[0001] This utility model relates to the field of automotive emergency jump starter technology, and more specifically, to an automotive emergency jump starter with a preheating function. Background Technology

[0002] With the development of the times, cars have entered ordinary households, bringing great convenience to people's travel. However, many problems also arise, such as cars failing to start under certain special circumstances, causing great inconvenience to users. Cars generally use batteries to start the engine. After the engine starts, it charges the battery through its own generator system. Under normal circumstances, the battery charge is balanced. However, due to factors such as battery aging, insufficient charging, long-term storage, or cold weather, the battery power supply may be insufficient, and the alternator may fail to start normally, affecting the normal use of the vehicle. The market has introduced car emergency jump starters. Currently, car emergency jump starters generally have a preheating structure to facilitate normal use in cold environments. However, existing preheating structures still have some problems. The preheating structure is usually placed directly on the front and rear sides of the emergency jump starter. This causes the contact area to heat up continuously, while other areas heat up slowly, resulting in uneven preheating. Moreover, direct contact can easily lead to overheating, which may damage the emergency jump starter and affect the effectiveness of the preheating structure.

[0003] Regarding the aforementioned issue of potential damage to the emergency jump starter, thus affecting the effectiveness of the preheating structure, extensive research revealed a patent (CN222465112U) for a car emergency jump starter with preheating function. This patent includes an insulated shell with a cover installed on the outer side of its opening. Two support frames are mounted on the upper side of the bottom side wall of the insulated shell. Limiting blocks are located on the front and rear sides of the upper side of each support frame, and a limiting baffle is located on the left side of the left support frame. An emergency jump starter body, which fits against the limiting blocks and baffle, is mounted on the upper sides of both support frames. Electric heating plates are installed on all four inner walls of the insulated shell. This invention, through the support frames, allows the emergency jump starter body to be suspended inside the insulated shell. The electric heating plates, mounted on the inner wall of the insulated shell, avoid contact with the emergency jump starter body. Thus, with the cooperation of the insulated shell and the cover, the space where the emergency jump starter body is placed is heated by the electric heating plates, allowing the entire space to be heated. However, the technical solution provided by this patent has the following problems:

[0004] (1) Existing car emergency jump starters have a simple structure and lack a buffer structure at the bottom. Moreover, the power supply is generally very heavy. If placed directly, it will cause impact collision between the insulation shell and the car or the ground, which will accelerate the damage of the car emergency jump starter.

[0005] (2) Existing car emergency jump starters do not have a unified connection wire system, and the connection wires are messy during daily storage and are easily damaged by friction;

[0006] (3) Existing car emergency jump starters are easy to move and have a heat insulation shell, but they cannot achieve the effect of being easy and portable.

[0007] This invention can prevent the insulation shell from impacting or colliding with cars or the ground, thus avoiding damage to the power supply, and can also store the connecting wires and make it easy to carry. Utility Model Content

[0008] The present invention aims to solve the technical problems mentioned in the background art and provide an emergency starter power supply for automobiles with a preheating function.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a car emergency jump starter with preheating function, comprising: an insulation shell, buffer blocks installed at the four corners of the bottom of the insulation shell, a fixed seat installed on the outer sleeve of the buffer block, a buffer spring installed inside the fixed seat, a connecting rod one and a connecting rod two symmetrically connected to the front and rear ends of the insulation shell, the connecting rod two being located directly below the connecting rod one, a connecting ring installed on the outer sleeve of the connecting rod two, a fixed block installed at the center of the upper end of the connecting ring, a through groove opened between the fixed blocks, a movable rod installed in the through groove, the movable rod being rotatably connected to the inside of the fixed block through a movable shaft, and a handle connected to the front and rear ends of the insulation shell through a rotating shaft.

[0010] A further preferred embodiment: The buffer block is composed of a hollow column in the upper part and a hollow ring in the lower part. The fixing seat is a hollow cylinder with an open top. The opening is circular and the diameter of the opening is equal to the outer diameter of the hollow column. The inner wall of the fixing seat fits against the outer wall of the hollow ring.

[0011] A further preferred embodiment: the buffer spring is fixedly connected to the bottom of the mounting base, and the other end of the buffer spring is connected to the bottom of the insulation shell.

[0012] A further preferred option: The number of connecting rods is 12, and a limiting groove is opened at the lower end of the connecting rod. The length of the limiting groove is less than the length of the connecting rod.

[0013] A further preferred embodiment: The number of connecting rods 2 is 12, and connecting grooves are symmetrically opened on the left and right ends of the connecting rods 2. The connecting grooves are located between the front and rear ends of the connecting rods 2, and the length of the connecting grooves is less than the length of the connecting rods 2.

[0014] A further preferred embodiment: the inner wall of the connecting ring has protrusions on the left and right ends, the protrusions fit perfectly with the connecting groove, the inner wall of the protrusions is magnetic, the protrusions attract the connecting groove, and the movable rod matches the limiting groove.

[0015] A further preferred option: There are two handles, the handles are n-shaped, and the maximum height of the handle is greater than the length of the handle from the end closer to the insulation shell. Beneficial effects

[0016] 1. By setting up a buffer block, a fixed seat and a buffer spring, when the insulation shell is placed, the fixed seat is in contact with the contact surface. At this time, the buffer spring is compressed by the insulation shell, and the buffer block moves up and down along the inner wall of the fixed seat. This provides a buffer effect for the insulation shell when it is placed, and avoids the insulation shell from impacting or colliding with the car or the ground, which could cause damage to the power supply.

[0017] 2. The system includes connecting rod one, connecting rod two, connecting ring, protrusion, fixing block, and movable rod. When the connecting wire needs to be stored, push the movable rod outwards by hand in sequence. The movable rod rotates outwards around the movable axis. Then, place the connecting wire between connecting rod one and connecting rod two. Then, push the movable rod upwards. The movable rod rotates inwards around the movable axis to its original position. At this time, the top of the movable rod is located in the limiting groove. Then, push the connecting ring to move the protrusion in the connecting groove. When the connecting ring touches the connecting wire, stop pushing. At this time, the protrusion attracts the connecting groove, so that the connecting ring is stabilized on connecting rod two, thus realizing the storage of the connecting wire.

[0018] 3. With a handle, when you need to carry the car emergency jump starter, simply rotate the handle around the pivot to the vertical direction to lift it up. When not in use, simply rotate the handle around the pivot to the horizontal direction, achieving an easy and portable effect.

[0019] 4. In summary, this type of car emergency jump starter with preheating function, by incorporating a buffer block, a fixing base, and a buffer spring, effectively prevents damage to the power supply caused by impacts or collisions between the insulation shell and the car or the ground; by incorporating a connecting rod, a fixing block, and a movable rod, it enables the storage of the connecting cable; and by incorporating a handle, it achieves an easy and portable effect.

[0024] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0025] Please see Figure 1-3 In this embodiment of the present invention, an emergency car jump starter with preheating function includes: an insulation shell 1, buffer blocks 2 installed at the four corners of the bottom of the insulation shell 1, a fixed seat 3 installed on the outer sleeve of the buffer block 2, a buffer spring 4 installed inside the fixed seat 3, a connecting rod 5 and a connecting rod 6 symmetrically connected to the front and rear ends of the insulation shell 1, the connecting rod 6 being located directly below the connecting rod 5, a connecting ring 7 installed on the outer sleeve of the connecting rod 6, a fixed block 8 installed at the upper center of the connecting ring 7, a through groove opened between the fixed blocks 8, a movable rod 9 installed in the through groove, the movable rod 9 being rotatably connected to the inside of the fixed block 8 through a movable shaft 10, and a handle 11 connected to the front and rear ends of the insulation shell 1 through a rotating shaft 12.

[0026] In this embodiment of the utility model, the buffer block 2 is composed of a hollow column in the upper part and a hollow ring in the lower part. The fixing seat 3 is a hollow cylinder with an open top and a circular opening. The diameter of the opening is equal to the outer diameter of the hollow column. The inner wall of the fixing seat 3 is in contact with the outer wall of the hollow ring. The buffer spring 4 is fixedly connected to the bottom of the fixing seat 3. The other end of the buffer spring 4 is connected to the bottom of the heat insulation shell 1. When the heat insulation shell 1 is placed, the fixing seat 3 is in contact with the contact surface. At this time, the buffer spring 4 is compressed by the heat insulation shell 1, and the buffer block 2 moves up and down along the inner wall of the fixing seat 3. This provides a buffer effect for the heat insulation shell 1 when it is placed, and avoids the heat insulation shell 1 from being impacted or collided with the car or the ground, thereby causing damage to the power supply.

[0027] In this embodiment of the utility model, there are 12 connecting rods 5. Each connecting rod 5 has a limiting groove at its lower end, the length of which is less than the length of the connecting rod 5. There are also 12 connecting rods 6. Each connecting rod 6 has symmetrical connecting grooves at its left and right ends, located between its front and rear ends. The length of these connecting grooves is less than the length of the connecting rod 6. The inner wall of the connecting ring 7 has protrusions 701 connected to its left and right ends. These protrusions 701 fit snugly against the connecting grooves. The inner wall of the protrusions 701 is magnetic, attracting the protrusions 701 to the connecting grooves. The movable rod 9 matches the limiting groove. To store the connecting cable, push the movable rod 9 outwards by hand. The movable rod 9 rotates outwards around the movable shaft 10. Then place the connecting cable between the connecting rod 5 and the connecting rod 6. Then push the movable rod 9 upwards. The movable rod 9 rotates inwards around the movable shaft 10 back to its original position. At this time, the top of the movable rod 9 is located in the limiting groove. Then push the connecting ring 7 to move the protrusion 701 in the connecting groove. When the connecting ring 701 touches the connecting cable, stop pushing. At this time, the protrusion 701 is attracted to the connecting groove, so that the connecting ring 7 is stable on the connecting rod 6, thus realizing the storage of the connecting cable.

[0028] In this embodiment of the utility model, there are two handles 11. The handles 11 are n-shaped handles. The maximum height of the handles 11 is greater than the length of the end of the handle 11 that is closer to the heat insulation shell. When carrying the car emergency jump starter, the handles 11 can be lifted by rotating them around the pivot 12 to the vertical direction. When normally placed, the handles 11 can be rotated around the pivot 12 to the horizontal direction.

[0029] Working principle: When the insulation shell 1 is placed, the fixing seat 3 is in contact with the contact surface. At this time, the buffer spring 4 is compressed by the insulation shell 1, and the buffer block 2 also moves up and down along the inner wall of the fixing seat 3, thus providing a buffer for the insulation shell 1 when it is placed, avoiding impact collisions between the insulation shell and the car or the ground, which could damage the power supply. When it is necessary to store the connecting wire, push the movable rod 9 outward by hand. The movable rod 9 rotates outward around the movable shaft 10. Then place the connecting wire between the connecting rod 5 and the connecting rod 6, and then push the movable rod 9 upward. The rod 9 rotates inward around the movable shaft 10 to its original position. At this time, the top of the movable rod 9 is located in the limiting groove. Then, the connecting ring 7 is pushed to drive the protrusion 701 to move in the connecting groove. When the connecting ring 701 touches the connecting wire, the pushing stops. At this time, the protrusion 701 is attracted to the connecting groove, so that the connecting ring 7 is stabilized on the connecting rod 6, realizing the storage of the connecting wire. When carrying the car emergency jump starter, the handle 11 can be lifted by rotating the shaft 12 to the vertical direction. When normally placed, the handle 11 can be rotated to the horizontal direction by rotating the shaft 12, achieving an easy and portable effect.
