Description

Technical Field

[0001] This utility model relates to the field of emergency power supply technology, and in particular to an emergency starter power supply with a mounting bracket. Background Technology

[0002] Emergency jump starters, as portable energy storage devices, are used in emergency situations where vehicles such as cars and ships cannot start due to a dead battery. By providing a powerful starting current in an instant, emergency jump starters can help the engine start smoothly and play an important role in daily life.

[0003] Currently available emergency jump starters on the market use energy storage units composed of multiple high-rate discharge lithium-ion batteries.

[0004] Lithium polymer batteries are connected in series and parallel. In order to output hundreds or even thousands of amperes of current in an instant, the battery cells need to discharge at a very high rate in a very short time. This process is inevitably accompanied by the Joule heating effect, which generates a lot of heat inside the battery.

[0005] However, most existing portable emergency jump starters focus on miniaturization and lightweight design, and do not adequately consider heat dissipation. Many products rely solely on natural convection of the casing for heat dissipation. When faced with repeated startups or use in high-temperature environments, the heat accumulated inside the battery cannot be dissipated in time. This not only accelerates the aging of battery materials, leading to capacity decay and increased internal resistance, but in severe cases, it can also induce thermal runaway, posing fire and explosion safety hazards.

[0006] In addition, the combined effects of high temperature and high-rate discharge can also cause side reactions and gas generation inside the battery, leading to physical bulging and expansion. This bulging not only disrupts the arrangement and connection of cells within the battery pack, but also squeezes and damages the overall structure of the power supply. It can even puncture the separator due to excessive internal stress, causing an internal short circuit. Existing technologies do not have structural designs that effectively constrain battery bulging, which significantly reduces the reliability and safety of the product after long-term use.

[0007] Therefore, this utility model proposes an emergency starter power supply with a mounting bracket to overcome the shortcomings of the prior art. Utility Model Content

In addition, the existing structures generally lack integrated design of physical limiting and efficient active heat dissipation. The present invention aims to provide an emergency jump starter with mounting brackets with an improved structure that can effectively solve the above problems.

[0012] Preferably, the emergency starter power supply with mounting bracket further includes a lifting handle, which is fixedly connected to the top of the main mounting bracket.

[0013] Preferably, the mounting and fixing mechanism further includes a side fixing bracket and an opening button. The side fixing bracket is fixedly connected to the bottom of the main fixing bracket, and the opening button is located on the rear side of the side fixing bracket.

[0016] Preferably, the heat dissipation mechanism further includes a lower connecting plate and a plurality of side connecting columns, the bottom of the water-cooling fin is fixedly connected to the top of the lower connecting plate, and the lower connecting plate is supported by the plurality of side connecting columns.

[0017] Preferably, the heat dissipation mechanism further includes a rear heat sink and a rear fixing member, which are fixedly connected to the rear side of the water-cooled plate to dissipate the heat carried by the cooling medium to the outside.

[0018] Preferably, the upper cooling plate tightly wraps around the upper guide tube through the opening of the cooling plate, and the upper cooling plate is attached to the top of the upper cooling plate, together forming a highly efficient heat conduction interface from the power battery to the upper guide tube.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting a limiting space formed by the inner fixing frame and the main fixing frame, applies physical compression force to the installed power battery, which solves the problem that the battery in the existing emergency starter power supply will bulge and expand due to internal gas generation during high-rate discharge, thus affecting the structural stability and safety.

It achieves the goal of quickly removing the heat generated by the battery, effectively controlling the battery operating temperature, ensuring that the emergency start-up power supply can operate stably and reliably under high load, and extending its service life.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example:

[0030] Please refer to Figure 1 and Figure 2 As shown, an emergency jump starter with a mounting bracket includes a main mounting bracket 1, a mounting and fixing mechanism 3, and a heat dissipation mechanism 4. A lifting handle 31 is fixedly connected to the top of the main mounting bracket 1, and a side mounting bracket 32 ​​is fixedly connected to the bottom of the main mounting bracket 1. An activation button 33 is located on the rear side of the side mounting bracket 32. The mounting and fixing mechanism 3 is used to accommodate and fix multiple power batteries 310, such as... Figure 3 As shown, the mounting and fixing mechanism 3 includes an inner fixing frame 35, a bottom mounting plate 34, an upper mounting plate 38, and a fixing post 39. The inner fixing frame 35 and the side wall of the main fixing frame 1 together form a limiting space for applying compressive force to the power battery 310. The inner fixing frame 35 is fixedly connected to the bottom mounting plate 34, and the upper mounting plate 38 and the fixing post 39 are fixedly connected to the top of the inner fixing frame 35. The front side of the inner fixing frame 35 is provided with a current-passing strip 36 and an external connection port 37. The current-passing strip 36 and the external connection port 37 are used to connect the circuits of multiple power batteries 310, such as... Figure 4 As shown, the heat dissipation mechanism 4 is used to dissipate heat from the power battery 310. The heat dissipation mechanism 4 includes an upper guide pipe 43, an upper cooling plate 44, an upper cooling plate 46, a water cooling plate 2, and a circulation pump. The upper guide pipe 43, the water cooling plate 2, and the circulation pump are connected in series to form a closed loop for circulating the cooling medium. The upper cooling plate 46 is attached to the top of the upper cooling plate 44 and together they cover the top of the power battery 310. The upper cooling plate 44 has a cooling plate opening 45 that wraps around the upper guide pipe 43. The heat dissipation mechanism 4 also includes a lower connecting plate 41 and multiple side connecting posts 42. The bottom of the water cooling plate 2 is fixedly connected to the top of the lower connecting plate 41. The lower connecting plate 41 is supported by multiple side connecting posts 42. The rear heat sink 47 and the rear fixing member 48 are fixedly connected to the rear side of the water cooling plate 2.

[0031] Please refer to Figure 3 and Figure 4The inner fixing frame 35 in the mounting and fixing mechanism 3 is fixedly installed inside the main fixing frame 1. The inner fixing frame 35 and the side wall of the main fixing frame 1 together form a size-controlled limiting space. Multiple power batteries 310 are tightly installed in this limiting space. This structural layout allows the mounting and fixing mechanism 3 to position the power batteries 310 while the side wall of the inner fixing frame 35 can apply a preset compressive force to the casing of the power batteries 310. This physically suppresses the bulging and expansion of the power batteries 310 during operation. At the same time, the heat absorption end structure of the heat dissipation mechanism 4 forms a tight contact with the power batteries 310. The upper cooling plate 46 is attached to the top of the upper cooling plate 44, and multiple cooling plates 44 are provided with... A cooling plate opening 45, whose shape is adapted to the outer wall of the upper guide tube 43, is provided. In the assembled state, the upper cooling plate 44 tightly wraps around the upper guide tube 43 through the cooling plate opening 45. The heat-conducting component composed of the upper cooling plate 46 and the upper cooling plate 44 together covers the top of the multiple power batteries 310 within the limiting space. This multi-layer composite tight-fitting structure ensures that the heat generated by the power battery 310 during operation can be quickly and with low thermal resistance conducted to the cooling medium in the upper guide tube 43. As for the specific selection of the cooling medium and the internal circuit controlled by the start button 33, those skilled in the art can use conventional fluids such as water and ethylene glycol mixtures and known circuit designs. Specific details are known in the art and will not be elaborated here.

[0032] In a preferred embodiment, to facilitate carrying and operating the entire device, a lifting handle 31 is fixedly connected to the top of the main mounting frame 1, allowing the user to lift the entire emergency start-up power supply by pulling the handle 31. A side mounting frame 32 is fixedly connected to the bottom of the main mounting frame 1 to stably place the entire device. An on / off button 33 is located on the rear side of the side mounting frame 32 to control the on / off state of the entire emergency start-up power supply circuit.

[0033] In a preferred embodiment, to further enhance the stability and structural integrity of the multiple power batteries 310, a bottom mounting plate 34 is fixedly connected to the bottom of the inner fixing frame 35, and an upper mounting plate 38 is fixedly connected to the top of the inner fixing frame 35 through a fixing post 39. The bottom mounting plate 34 and the upper mounting plate 38 limit the power batteries 310 from the bottom and top respectively, and together with the lateral compression cooperation formed by the inner fixing frame 35 and the main fixing frame 1, they form a stable housing structure.

[0034] In a preferred embodiment, in order to achieve reliable power collection and output among multiple power batteries 310, a flow strip 36 and an external connection port 37 are provided on the front surface of the inner fixing frame 35. The flow strip 36 is used to connect the electrodes of multiple power batteries 310 in series and parallel to form a unified power module. The external connection port 37 serves as the electrical interface of the entire device to the outside world, used to connect external devices that need to be started.

[0035] In a preferred embodiment, in order to provide a stable mounting base for the heat dissipation mechanism 4 and achieve the final heat exchange, the bottom of the water-cooled plate 2 is fixedly connected to the top of the lower connecting plate 41. The four corners of the lower connecting plate 41 are supported by multiple side connecting columns 42 to form a sturdy base. At the same time, a rear heat sink 47 is fixedly connected to the rear side of the water-cooled plate 2 by a rear fixing member 48. The rear heat sink 47 has a large heat dissipation area and is used to efficiently dissipate the heat generated by the cooling medium circulating in the closed loop to the surrounding environment.

[0036] Working principle:

[0037] When an emergency start-up power supply is needed, the operator presses the start button 33 located on the rear side of the side mounting bracket 32. At this time, multiple power batteries 310 installed in the limiting space formed by the inner mounting bracket 35 and the main mounting bracket 1 begin to discharge with a large current. During the discharge process, a large amount of heat is generated inside the power batteries 310 due to chemical reactions, accompanied by an increase in internal pressure, which poses a risk of bulging and expansion. The installation and fixing mechanism 3 of this utility model continuously applies a certain amount of compressive force to the multiple power batteries 310 through the formed limiting space. This physical constraint can effectively suppress the deformation of the power battery 310 shell, prevent the occurrence and aggravation of bulging, and ensure the structural integrity and safety of the battery pack. At the same time, the heat dissipation mechanism 4 begins to work in coordination. The heat generated by the power batteries 310 is first conducted to the upper cooling plate 46 and the upper cooling plate 44 that are tightly covered on the top of the power batteries 310. Since the upper cooling plate 44 is tightly wrapped through the cooling plate opening 45, Encased in the upper guide tube 43, a highly efficient heat-conducting interface is formed. Heat is rapidly transferred from the upper cooling plate 46 and the upper cooling plate 44 to the upper guide tube 43 and absorbed by the cooling medium flowing inside the tube. Driven by the circulating pump, the heated cooling medium circulates along the closed loop formed by the upper guide tube 43 and the water-cooled plate 2 components connected in series. When the cooling medium carrying heat flows through the water-cooled plate 2, the heat is conducted to the rear heat sink 47, which is fixedly connected to the water-cooled plate 2. The rear heat sink 47, with its large heat dissipation area, efficiently dissipates the heat into the surrounding air, completing the heat exchange process. The cooled cooling medium continues to flow back to the upper guide tube 43 under the action of the circulating pump, ready to absorb a new round of heat. Through the combined effect of the physical limiting of the mounting and fixing mechanism 3 and the active water cooling of the heat dissipation mechanism 4, this utility model effectively solves the problem of the power battery 310 bulging and being damaged due to overheating, ensuring the reliability and service life of the emergency start-up power supply under extreme conditions.
