Description

Technical Field

[0001] This invention relates to the field of emergency power supply technology, specifically a low-temperature emergency start-up power supply device. Background Technology

[0002] Emergency jump starters, as a type of portable energy storage device, are mainly used to provide temporary starting power support when vehicles such as cars, ships, and construction machinery cannot start normally due to sudden situations such as battery depletion or malfunction. With their advantages of portability and ease of operation, they have been widely used in daily travel, outdoor operations, emergency rescue and other scenarios.

[0003] Existing low-temperature emergency start-up power supplies still have some technical problems in use, such as:

[0004] 1. When using existing emergency start-up power supplies, the power cords connecting to other equipment are usually placed separately, which makes them easy to lose;

[0005] 2. Existing emergency start-up power supply devices are designed to be used on inclined slopes, which limits their application.

[0006] 3. The panel of existing emergency starter power devices is generally exposed, which makes it easy for them to collide and rub against the casing when being carried, resulting in damage or even destruction, which is not conducive to ensuring their service life.

[0007] Therefore, a low-temperature emergency start-up power supply device is needed to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a low-temperature emergency start-up power supply device to solve the problems mentioned in the background art, such as the existing low-temperature emergency start-up power supply devices having a separate power cord that is easy to lose, being inconvenient to use on inclined slopes, and providing insufficient protection for the panel.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A low-temperature emergency start-up power supply device includes a housing and four folding slots on its lower surface. The housing has a doorway on its side, with two dust covers spun onto the doorway. The lower surface of the housing has a recessed hole, within which a support column extends movably into the housing. The lower surface of each support column has a cross-shaped groove, within which four support bars are connected via damping bearings. Each support bar is connected to a connecting bar via a telescopic mechanism, which includes mounting slots for engaging the sliding connecting bars. Each support bar has a mounting slot on its lower surface. The upper end of each support column is connected to a wiring panel via a displacement drive mechanism, which includes a piston rod connected to the top of the housing. The upper and lower ends of the wiring panel are slidably connected to the upper and lower sides of the housing via a slider-sliding groove structure. The housing also includes an adaptive heat dissipation mechanism, which includes a mounting bracket fixedly connected to the housing.

[0011] Furthermore, the dust cover rotates in a vertical direction, the doorway is a convex through-slot structure, and the larger opening of the doorway matches the structural dimensions formed by the two dust covers, while the smaller opening of the doorway matches the dimensions of the wiring panel.

[0012] Furthermore, the telescopic mechanism also includes limiting holes equally spaced on both sides of the support bar, and the limiting holes are connected to the corresponding mounting grooves. One end of the connecting bar is provided with a through hole that passes through both sides, and both ends of the through hole slide through a limiting post. A spring is provided between the two opposing limiting posts, and the limiting posts are engaged and connected in the corresponding limiting holes.

[0013] Furthermore, the width of the support bar matches the inner width of the folding groove, making it easy for the support bar to be stored in the corresponding folding groove after rotation. The cross-section of the mounting groove is a cross-shaped structure, which ensures that the connecting bar can only slide along the axis of the mounting groove and cannot rotate relative to the mounting groove.

[0014] Furthermore, the displacement driving mechanism also includes a piston chamber disposed at the upper end of the support column, and the lower end of the piston rod movably penetrates the support column into the interior of the piston chamber. The piston chamber is an inverted T-shaped structure, and a spring is disposed between the lower end of the piston chamber and the inner bottom end of the piston chamber. Two support frames are symmetrically disposed at the upper end of the support column, and each support frame has an inclined groove on its end side. Two symmetrical connecting rods are disposed on the wiring panel, and a guide block is fixedly connected to each connecting rod. The guide block is slidably connected in the corresponding inclined groove.

[0015] Furthermore, the recessed hole has a reserved hole for the support column to move through into the interior of the shell. The support column has an I-shaped structure, and the diameter of its upper end is larger than the inner diameter of the reserved hole.

[0016] Furthermore, the adaptive heat dissipation mechanism includes heat dissipation holes penetrating both the inner and outer sides of the housing, and the heat dissipation holes are evenly distributed in each folding groove. The lower surface of the mounting bracket is provided with a recessed hole at a position corresponding to the folding groove, and the lower end of the recessed hole movably passes through a piston bracket. The lower surface of the piston bracket is provided with a sealing strip, and the sealing strip is engaged and connected to the corresponding heat dissipation hole. The inner top end of the recessed hole is connected to the upper end of the corresponding piston bracket by a memory spring.

[0017] Furthermore, the inner top of the recessed hole is provided with a vent hole that extends to the upper surface of the mounting bracket, so that the memory spring can sense the temperature inside the housing.

[0018] Furthermore, the mounting bracket is an I-shaped structure that is narrower at the top and wider at the bottom, and the mounting bracket moves through the recessed hole in its middle. The recessed hole is a convex structure, and the minimum inner diameter of the recessed hole matches the middle outer diameter of the mounting bracket. The upper diameter of the mounting bracket is greater than the minimum inner diameter of the recessed hole, and the upper diameter of the mounting bracket is less than the maximum inner diameter of the recessed hole.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the low-temperature emergency start-up power supply device can conveniently store the power cord, thereby avoiding the problem of the power cord being lost by storing it separately; in addition, it can be used horizontally on a slope, which helps to reduce its usage limitations; furthermore, it can protect the wiring panel, preventing it from being exposed, thus avoiding friction and impact between it and the housing, which helps to extend the service life of the wiring panel.

[0020] 1. The recessed hole and the I-shaped support column installed inside it allow the power cord to be stored in the recessed hole by winding around the middle of the support column, and the support strip limits the position of the power cord, thereby ensuring that the power cord will not be lost due to being placed alone.

[0021] 2. The housing can be suspended and supported by the support bars and the connecting bars installed on them. By adjusting the rotation angle of the support bars and the movement of the connecting bars on the support bars, the housing can be stably and horizontally supported on the slope, thereby reducing the limitations of its use.

[0022] 3. When the support bar and connecting bar are stored in the folding groove, the spring is in its natural state. At this time, the wiring panel is inside the housing, so it will not collide or rub against the box, which helps to protect it. When the support bar and connecting bar are supported in the use position, the housing and its internal electronic components will cause the support column to move gradually into the housing. Then, through the inclined groove and guide block, the wiring panel can slide inside the housing until it lifts the dust cover and is exposed to the outside, so as to facilitate wiring.

[0023] 4. When the support strip and connecting strip are stored in the folding groove, the heat dissipation hole will be blocked, thus preventing heat dissipation and making it difficult for external dust to enter the interior of the housing. When the support strip and connecting strip are supported in the use position and the electronic components inside the housing generate high heat, the memory spring will contract, thereby causing the sealing strip to disengage from the heat dissipation hole, so as to facilitate heat dissipation inside the housing.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-12 The present invention provides a technical solution:

[0039] A low-temperature emergency start-up power supply device includes a housing 1 and four folding grooves 7 on its lower surface. A doorway 19 is provided on the side of the housing 1, and two dust covers 2 are axially connected to the doorway 19. A recessed hole 3 is provided on the lower surface of the housing 1, and a support column 4 is provided within the recessed hole 3, extending movably into the housing 1. A cross-shaped groove is provided on the lower surface of the support column 4, and four support bars 5 are connected to the cross-shaped groove via damping bearings. Connecting bars 6 are connected to the support bars 5 via a telescopic mechanism. The telescopic mechanism includes mounting grooves 25 for engaging the sliding connecting bars 6. Mounting grooves 25 are provided on the lower surface of each support bar 5. The telescopic mechanism also includes... Equally spaced limiting holes 24 are provided on both sides of the support bar 5, and the limiting holes 24 are connected to the corresponding mounting grooves 25. One end of the connecting bar 6 is provided with a through hole 26 that passes through both sides, and both ends of the through hole 26 slide through the limiting post 28. A spring 27 is provided between the two opposing limiting posts 28, and the limiting post 28 is engaged with the corresponding limiting hole 24. The width of the support bar 5 matches the inner width of the folding groove 7, so that the support bar 5 can be stored in the corresponding folding groove 7 after rotation. The cross section of the mounting groove 25 is a cross-shaped structure, which makes it easy to ensure that the connecting bar 6 can only slide along the axis of the mounting groove 25 and cannot rotate relative to the mounting groove 25.

[0040] The upper end of the support column 4 is connected to a wiring panel 16 via a displacement drive mechanism. The displacement drive mechanism includes a piston rod 10 connected to the top of the housing 1. Both the upper and lower ends of the wiring panel 16 are slidably connected to the upper and lower sides of the housing 1 via a slider groove structure 20. An adaptive heat dissipation mechanism is also provided inside the housing 1. The displacement drive mechanism also includes a piston cavity 9 located at the upper end of the support column 4. The lower end of the piston rod 10 extends through the support column 4 into the piston cavity 9. The piston cavity 9 has an inverted T-shaped structure. A spring 11 is provided between the lower end and the inner bottom end of the piston chamber 9. Two support frames 12 are symmetrically provided on the upper end of the support column 4, and each support frame 12 has a slanted groove 13 on its end side. Two symmetrical connecting rods 15 are provided on the wiring panel 16, and a guide block 14 is fixedly connected to each connecting rod 15. The guide block 14 is slidably connected in the corresponding slanted groove 13. A reserved hole is reserved in the recessed hole 3 for the support column 4 to move through into the interior of the housing 1. The support column 4 has an I-shaped structure, and the diameter of its upper end is larger than the inner diameter of the reserved hole.

[0041] The adaptive heat dissipation mechanism includes a mounting bracket 17 fixedly connected inside the housing 1. The dust cover 2 rotates in a vertical direction. The door opening 19 is a convex through-slot structure, and the larger opening of the door opening 19 matches the structural dimensions formed by the two dust covers 2. The smaller opening of the door opening 19 matches the dimensions of the wiring panel 16. The adaptive heat dissipation mechanism includes heat dissipation holes 8 penetrating both the inner and outer sides of the housing 1, and the heat dissipation holes 8 are evenly distributed in each folding groove 7. A recessed hole 21 is provided on the lower surface of the mounting bracket 17 at a position corresponding to the folding groove 7, and the lower end of the recessed hole 21 movably passes through a piston bracket 18. A sealing strip 23 is provided on the lower surface of the piston bracket 18, and the sealing strip 23... 3. The recessed hole 21 is connected to the corresponding heat dissipation hole 8. The inner top end of the recessed hole 21 is connected to the upper end of the corresponding piston bracket 18 through the memory spring 22. The inner top end of the recessed hole 21 is provided with a vent hole that extends to the upper surface of the mounting bracket 17, so that the memory spring 22 can sense the temperature inside the housing 1. The mounting bracket 17 is an I-shaped structure that is narrow at the top and wide at the bottom. The mounting bracket 17 moves through the recessed hole 21 through its middle part. The recessed hole 21 is a convex structure. The minimum inner diameter of the recessed hole 21 matches the middle outer diameter of the mounting bracket 17. The upper diameter of the mounting bracket 17 is greater than the minimum inner diameter of the recessed hole 21, and the upper diameter of the mounting bracket 17 is less than the maximum inner diameter of the recessed hole 21.

[0042] When using it, first take it out of the box where it is stored, and then take out the support strip 5 from the folding slot 7;

[0043] During the process of removing the support bar 5, the support bar 5 will rotate through the damping bearing connected to the support column 4. When all the support bars 5 have rotated to be perpendicular to the lower surface of the housing 1, manually wind the power cord wrapped around the middle of the support column 4 to remove the power cord from the support column 4.

[0044] Subsequently, based on the installation location of the emergency start-up power supply device, the four support bars 5 are rotated to a suitable angle, and the connecting bars 6 are extended a certain distance beyond the corresponding support bars 5. The specific process of extending the connecting bars 6 is as follows:

[0045] Press the two limiting posts 28 to completely disengage the two limiting posts 28 from the corresponding limiting holes 24, then pull the connecting strip 6 to slide a distance on the corresponding support strip 5. Then release your hand, and the limiting posts 28 will be reset under the action of the second spring 27 and engage with the corresponding limiting holes 24 at this time, thereby fixing the position of the connecting strip 6 on the corresponding support strip 5.

[0046] After the housing 1 is supported in the installation position by the connecting strip 6, under the gravity of the housing 1 and its internal electronic components, the upper end of the support column 4 will gradually move closer to the inner top of the housing 1, thereby causing the piston rod 10 to gradually move closer to the inner bottom of the piston chamber 9, thus compressing the spring 11.

[0047] During the process, the support frame 12 connected to the support column 4 will move relative to the connecting rod 15, so that the guide block 14 on the connecting rod 15 can slide in the corresponding inclined groove 13, causing the connecting rod 15 to move towards the dust cover 2.

[0048] When the connecting rod 15 moves, it synchronously drives the wiring panel 16 to move. When the wiring panel 16 moves, it will come into contact with the dust cover 2, thereby causing the dust cover 2 to flip so that the wiring panel 16 is exposed outside the housing 1, which facilitates subsequent wiring operations.

[0049] During the above process, if the emergency start-up power supply is stored in the housing, that is, when the support bar 5 is stored in the folding groove 7, the heat dissipation hole 8 is not only sealed by the sealing bar 23, but also by the support bar 5, thereby preventing external dust from entering the interior of the housing 1 and helping to ensure the stability of the electronic components inside the housing 1.

[0050] When the emergency start-up power supply is in use, the heat dissipation hole 8 will still be sealed by the sealing strip 23 when the internal temperature is low, which helps to increase the temperature inside the housing 1 and ensure the normal operation of electronic components. When the temperature inside the housing 1 is too high, the memory spring 22 will contract, causing the piston frame 18 to move upward. At this time, the sealing strip 23 on the lower surface of the piston frame 18 will separate from the heat dissipation hole 8, which helps to exchange heat between the inside and outside of the housing 1, thereby helping to cool the inside of the housing 1.

[0051] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
