Description

Technical Field

[0001] This invention relates to the field of automotive emergency jump starter housing technology, specifically a split-type, shock-resistant, detachable automotive jump starter housing. Background Technology

[0002] Automotive emergency jump starters are widely used in emergency rescue scenarios for passenger cars, commercial vehicles, and construction machinery when vehicles are out of power. These devices are stored in vehicles for extended periods and continuously endure complex mechanical environments such as road bumps, instantaneous impacts, and sudden braking vibrations during driving. They also face conditions such as rain, car washes, outdoor wading through water, and corrosion from dust and oil. Therefore, the power supply casing has stringent requirements for shock absorption, waterproof sealing, and maintenance performance. Currently, most mainstream automotive jump starters on the market use an integrated injection-molded casing, with the internal battery and protection board integrated, which is the common structural solution for current vehicle emergency power supplies.

[0003] Existing integrated automotive starter housings have several significant drawbacks in practical use: First, they have weak shock resistance. The battery module and control module are in direct, rigid contact with the housing, relying only on a small amount of simple foam for localized cushioning. Vehicle vibrations are rigidly transmitted to the battery cells and circuit boards, easily causing component desoldering and cell damage from impacts. The rigid copper busbars connecting the battery and control board can easily pull on the solder joints when vibrations cause relative displacement, leading to circuit breaks and sparking malfunctions. Second, their waterproof and dustproof protection is inadequate. Only the housing seams are sealed with a single layer of adhesive; the wiring holes, external plugs, and top electrode posts lack corresponding sealing structures, allowing liquids and sediment to easily seep into the housing, causing short circuits and corrosion. Third, they are inconvenient for inspection and maintenance. The housing is secured with screws and clips, requiring specialized tools for disassembly. There are no independent internal compartments; the battery and control board are tangled and stacked, making it impossible to replace a single faulty module, necessitating the scrapping of the entire unit and resulting in high maintenance costs. Fourth, they lack internal physical isolation structures, allowing heat from the battery cells to be directly conducted to the control circuit, posing safety hazards such as thermal crosstalk and overheating runaway.

[0004] Therefore, a split-type, shock-resistant, detachable automotive starter power supply housing is proposed to solve the aforementioned problems. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a split-type shock-resistant detachable car starter housing, which solves the problems of poor shock absorption, low waterproof and dustproof protection, cumbersome module disassembly and maintenance, and thermal interference caused by the lack of physical isolation between the battery cell and the control circuit in traditional integrated starter housings.

The control module is correspondingly assembled and housed inside the main control compartment of the main housing. The control module and the battery module are electrically connected through a flexible connection component, which forms a floating electrical connection structure between the control module and the battery module without rigid contact.

[0007] Preferably, the lower shell and the upper shell are both integrally injection molded from high-strength engineering plastic material, and the two are combined to form an upper and lower split composite shell structure. The lower shell is provided with an annular sealing groove at its edge, and the bottom of the upper shell is provided with an annular protrusion that matches the annular sealing groove. The annular protrusion is embedded in the annular sealing groove and then filled with sealant to complete the sealing fit.

[0008] Preferably, the battery compartment and the main control compartment are completely separated by a partition rib inside the main housing. The partition rib is integrally formed with the lower housing and the upper housing. Only small wiring through holes are reserved on the partition rib for the soft connection components to pass through. Sealing rings are provided at the wiring through holes to seal the gaps.

[0009] Preferably, the flexible connection component is a flexible conductive copper strip connector. One end of the flexible connection component is welded and fixed to the total output electrode of the battery module, and the other end of the flexible connection component is locked and fixed to the input terminal of the control module. Relying on the flexible deformation capability of the flexible connection component itself, it absorbs displacement when the shell is subjected to vibration and impact, and maintains the continuous conduction of the circuit.

[0010] Preferably, the sealing interface module is a waterproof aviation plug structure, with an integrally formed waterproof sealing ring surrounding the outer side of the plug body; the sealing interface module and the outer wall of the lower housing are assembled with an interference fit.

[0011] Preferably, the shock-absorbing silicone pad is made of high-temperature resistant silicone material and is molded. The silicone pad has fitting grooves according to the outline of the battery module and the control module, and the module is inserted into the corresponding groove to achieve full wrapping and limiting.

[0012] Preferably, the joint sealing structure of the lower shell and the upper shell, the embedded waterproof structure of the sealing interface module, and the sealing ring of the wiring through hole cooperate with each other to form the sealing and protection structure of the whole machine; after assembly, the whole machine can be immersed in water without any liquid seepage channels inside the shell.

[0013] Preferably, the battery module and control module are both set as independent standardized modular units, and the battery compartment and main control compartment have no locking buckle structure to restrict the removal of the modules; during disassembly, only the lower shell and the upper shell need to be separated, and the battery module and control module can be directly removed from the corresponding compartment by hand without the need for special disassembly tools.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a split-type shock-absorbing and detachable car starter housing, which has the following advantages: 1. This split-type shock-resistant detachable car jump starter housing utilizes a high-temperature resistant silicone full-wrap buffer structure to block the transmission of rigid vibrations between the housing and the battery cell and circuit board. It relies on the elastic deformation of the silicone to disperse the impact, preventing damage to the battery cell from bumps and breakage and desoldering of circuit board components. It is suitable for long-term bumpy driving conditions of vehicles and improves the service life of the power supply.

[0016] 2. This split-type shock-resistant detachable car starter power supply housing utilizes a flexible copper strip soft connection floating conductive structure to eliminate rigid hard limits between the battery module and the control module. Under vibration, it adaptively cancels the relative displacement between the two, continuously ensuring stable circuit conduction and eliminating the risk of circuit breakage and arcing caused by displacement and pulling of traditional hard copper busbar connections.

[0017] 3. This split-type shock-resistant detachable car jump starter housing utilizes a multi-seal waterproof structure, with all seams, wiring holes, external interfaces, and electrode output positions fully sealed, achieving a high level of waterproof and dustproof performance. It can be used stably in outdoor, rainy, and water-filled vehicle scenarios, making it suitable for a wider range of applications.

[0018] 4. This split-type, shock-resistant, detachable car jump starter housing utilizes a modular, unlockable upper and lower compartment design, eliminating the need for screws or clip tools for disassembly and assembly. The battery and control module can be individually removed and replaced, simplifying maintenance and reducing overall wear and tear, thus lowering future maintenance costs. The internal dual-compartment integrated structure isolates the battery cells from the control circuitry, reducing the risk of thermal runaway and circuit crosstalk, resulting in enhanced safety.

[0021] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 - Figure 5As shown, a split-type shock-absorbing detachable automotive starter power supply housing includes a lower housing 1, an upper housing 2, a battery module 3, shock-absorbing silicone pads 4, high-temperature resistant silicone, with a shock resistance level meeting the automotive ISO16750 standard, a control module 5, a flexible connection assembly 6, and a sealed interface module with a insertion / removal life ≥5000 cycles. The lower housing 1 and upper housing 2 are interlocked to form the main housing. An integrally formed partition rib divides the internal space of the main housing into two independent enclosed cavities: a battery compartment and a main control compartment. The battery module 3 is detachably assembled and stored in the battery compartment inside the lower housing 1. The battery module 3 is composed of multiple lithium iron phosphate battery packs of various specifications arranged together. The shock-absorbing silicone pads 4 are respectively wrapped and attached to the outer periphery of the battery module 3 and the outer periphery of the control module 5. After the shock-absorbing silicone pads 4 are completed, they elastically abut against the inner walls of the lower housing 1 and the upper housing 2 respectively. The control module 5 is correspondingly assembled and stored inside the main control compartment of the main housing. The control module 5 and the battery module 3 are electrically connected through the flexible connection component 6. The flexible connection component 6 makes the control module 5 and the battery module 3 form a floating electrical connection structure without rigid contact. The sealing interface module is embedded and fixed in the reserved installation position on the outer wall of the lower housing 1. The sealing interface module passes through the housing wall and is sealed and electrically connected to the control module 5 inside the main control compartment. The joint formed by the snap-fit ​​of the lower housing 1 and the upper housing 2 is filled with sealant to completely seal the joint. The battery compartment has dimensions of 228×173×107mm and a protection level of IP67, which can be immersed in 1 meter of water for 30 minutes without leakage.

[0023] First, both the lower shell 1 and the upper shell 2 are integrally injection molded from high-strength engineering plastic material. The two together form an upper and lower split composite shell structure. The lower shell 1 has an annular sealing groove on its edge, and the bottom of the upper shell 2 has an annular protrusion that matches the annular sealing groove. The annular protrusion is embedded in the annular sealing groove and then filled with sealant to complete the sealing fit. By integrally injection molding the lower shell 1 and the upper shell 2 from high-strength engineering plastic, the shell is lightweight while having high resistance to compression and impact, making it suitable for vehicle bumps and collisions. The upper and lower shell 2 split composite structure allows the whole machine to be directly disassembled and opened for easy internal module maintenance. The annular sealing groove of the lower shell 1 and the annular protrusion of the upper shell 2 are interlocked and positioned, and then the groove is filled with sealant, which greatly increases the sealing contact area of ​​the shell splicing surface, forming the first waterproof sealing barrier of the whole machine and preventing liquids and dust from seeping into the internal cavity from the joint between the upper and lower shells.

[0024] Secondly, the battery compartment and the main control compartment are completely separated by a partition rib inside the main housing. The partition rib is integrally formed with the lower housing 1 and the upper housing 2. Only small wiring through holes are reserved on the partition rib for the flexible connection component 6 to pass through. Sealing rings are installed at the wiring through holes to seal the gaps. The partition rib, which is integrally formed with the lower housing 1 and the upper housing 2, divides the interior of the housing into independent battery compartment and main control compartment, realizing physical isolation between battery module 3 and control module 5, blocking the direct conduction of heat from the battery cell to the control circuit board, and reducing the risk of thermal crosstalk and overheating runaway. The partition rib only has narrow wiring through holes for the flexible connection component 6 to pass through, reducing the gaps between the inside and outside. The sealing rings are fitted to the through holes to tightly wrap the flexible connection component 6, sealing the gaps in the through holes, forming the second internal sealing line of the whole machine, preventing moisture and dust from entering the compartment along the wiring channels.

[0025] Furthermore, the flexible connection component 6 is a flexible conductive copper strip connector. One end of the flexible connection component 6 is welded and fixed to the main output electrode of the battery module 3, and the other end of the flexible connection component 6 is locked and fixed to the input terminal of the control module 5. Relying on the flexible deformation capability of the flexible connection component 6 itself, it absorbs displacement when the shell is subjected to vibration and impact, and maintains continuous circuit conduction. The flexible conductive copper strip is used as the flexible connection component 6, with one end welded and fixed to the main electrode of the battery module 3 and the other end locked and fixed to the terminal of the control module 5, to establish a stable conductive path. With the flexible deformation characteristics of the flexible connection component 6, which can be bent and stretched, it absorbs the relative displacement between the battery module 3 and the control module 5 when the vehicle is vibrating, replacing the rigid connection of the traditional hard copper busbar, avoiding cracking, loose connection and arcing caused by pulling the electrode solder joint, maintaining stable circuit conduction throughout the process, and improving the vibration resistance and electrical reliability.

[0026] Furthermore, the sealing interface module is a waterproof aviation plug structure, with an integrated waterproof sealing ring surrounding the outer side of the plug body; the sealing interface module and the outer wall of the lower housing 1 are assembled with an interference fit. The sealing interface module uses a waterproof aviation plug with an integrated waterproof sealing ring, which is interference-fitted into the reserved installation position on the side wall of the lower housing 1. The sealing ring is squeezed tightly against the outer wall of the lower housing 1, completely sealing the assembly gap between the plug and the housing, forming the third external interface sealing barrier of the whole machine, preventing mud, water, oil, and dust from seeping into the cavity from the external interface. At the same time, the aviation plug has a long insertion and removal life and is not prone to sealing failure after long-term use.

[0027] Furthermore, the shock-absorbing silicone pad 4 is made of high-temperature resistant silicone material and molded. The silicone pad has fitting grooves according to the outline of the battery module 3 and the control module 5. The entire module is inserted into the corresponding groove to achieve full enclosure and limitation. The shock-absorbing silicone pad 4 is made of high-temperature resistant silicone and molded in one piece. It can withstand the high temperature of the battery cell without aging and failure. The silicone pad has fitting grooves inside that match the outline of the battery module 3 and the control module 5. The two modules are inserted into the entire module to achieve full enclosure and limitation, eliminating the rigid contact between the module and the inner wall of the lower shell 1 and the upper shell 2. It absorbs the vibration impact by relying on the elastic deformation of the silicone, cuts off the vibration path transmitted from the shell to the battery cell and the circuit board, and avoids the battery cell from being bumped and broken and the circuit board components from being desoldered.

[0028] Furthermore, the joint sealing structure of the lower shell 1 and the upper shell 2, the embedded waterproof structure of the sealing interface module, and the sealing ring of the wiring through hole work together to form the overall sealing and protection structure of the machine. After assembly, the whole machine can be immersed in water without any liquid seepage channels inside the shell. The three-layer sealing structure of the joint sealing of the lower shell 1 and the upper shell 2, the plug sealing of the sealing interface module, and the sealing ring of the wiring through hole of the partition rib work together to completely seal all the internal and external connecting gaps of the shell, forming a complete sealing and protection system. The whole machine can be immersed in water for a short time without any liquid seepage channels, effectively resisting the corrosion of rainwater, car wash sewage, and outdoor dust and oil.

[0029] Furthermore, both battery module 3 and control module 5 are set as independent, standardized, and modular units. The battery compartment and main control compartment have no locking or buckle structures to restrict module removal. During disassembly, only the lower shell 1 and the upper shell 2 need to be separated, and the battery module 3 and control module 5 can be removed by hand directly from their respective compartments without the need for special disassembly tools. The battery module 3 and control module 5 are designed as independent, standardized units, and there are no buckles or bolt locking structures inside the battery compartment and main control compartment. Only the lower shell 1 and the upper shell 2 need to be separated, and the battery module 3 or control module 5 can be removed by hand without the need for special disassembly tools such as screwdrivers. In case of failure, the damaged module can be replaced individually without scrapping the entire machine, which greatly reduces the later maintenance costs.

[0030] Finally, two positive and negative electrode output posts are vertically installed through the top surface of the upper housing 2. A ring-shaped waterproof gasket is installed at the contact point between the outer wall of the positive and negative electrode output posts and the upper housing 2. The lower ends of the positive and negative electrode output posts extend into the main control compartment and are electrically connected to the power output circuit of the control module 5. The upper ends of the positive and negative electrode output posts are exposed on the outside of the upper housing 2 for connecting external loads. The positive and negative electrode output posts are installed through the top surface of the upper housing 2. A ring-shaped waterproof gasket is installed between the electrodes and the through holes of the upper housing 2 to seal the electrode assembly gaps, forming a fourth sealing point to prevent liquids and dust from seeping into the main control compartment along the electrode gaps. The lower ends of the electrodes are connected to the power output circuit of the control module 5, and the upper ends are exposed for connecting external loads, ensuring high-power output while providing comprehensive waterproof protection for the entire machine.

[0031] Working principle: The device consists of a lower shell 1 and an upper shell 2 that are fastened together to form a closed main shell. The main shell has an integrally formed partition rib that divides the cavity into two main areas: the battery compartment and the main control compartment. The battery module 3 is stored separately in the battery compartment, and the control module 5 is stored separately in the main control compartment. The two are physically isolated.

[0032] During vehicle operation, continuous bumps and impacts are generated. The shock-absorbing silicone pad 4, which wraps around and fits the outer contour of the battery module 3 and control module 5, completely covers the two core electrical modules. The shock-absorbing silicone pad 4 makes all-round elastic contact with the inner cavity wall of the lower shell 1 and the inner bottom surface of the upper shell 2. The shock-absorbing silicone pad 4 is made of high-temperature resistant silicone through one-piece molding, and its internal deformation buffering margin is reserved. When the vehicle vibration and impact are transmitted from the shell structure of the lower shell 1 and upper shell 2 inward, the shock-absorbing silicone pad 4 relies on the elastic compression and rebound deformation ability of its silicone material to absorb, disperse and attenuate the external vibration and impact energy layer by layer, cutting off the rigid connection between the shell and the internal battery module 3 and control module 5. The force transmission path avoids the direct rigid transmission of high-frequency vibrations and instantaneous impacts to internal precision electrical components such as battery cells, circuit boards, and solder joints. A complete conductive path is established between the battery module 3 and the control module 5 inside the main control compartment through a flexible connection component 6. The flexible connection component 6 is made of flexible conductive copper strip, which has the deformation allowance to be freely bent and stretched. This creates a floating electrical connection structure between the battery module 3 and the control module 5 without rigid metal joints or rigid limits. Under vehicle bumpy conditions, the battery module 3 and the control module 5 will experience slight relative displacement due to vibration. The flexible connection component 6 can synchronously follow the bending deformation of the two modules to offset the positional offset between them, continuously maintain a stable conductive path, and prevent the force from being transmitted due to rigidity. To prevent electrode solder joint cracking and detachment, conductive terminal contact failure, and circuit breakage caused by tensile stress and relative displacement, the lower housing 1 has an integrally formed annular sealing groove around its top edge. The upper housing 2 has an annular protrusion at the bottom corresponding to the size of the annular sealing groove. During assembly, the annular protrusion is fully embedded into the annular sealing groove, and then sealant is filled and cured to form the first sealing barrier at the joint of the upper and lower housings. The partition rib separating the battery compartment and the main control compartment has only narrow, small wiring through-holes for the flexible connection component 6 to pass through. Sealing rings are fitted at the wiring through-holes to completely seal the gaps, forming the second internal wiring sealing barrier. A dedicated mounting position is reserved on the outer wall of the lower housing 1, and the sealing interface module is integrally formed. The waterproof aviation plug structure with waterproof sealing ring has an interference fit between the sealing interface module and the mounting hole of the lower housing 1. The plug sealing ring is tightly attached to the outer wall of the housing to seal the gap of the external interface, forming a third external interface sealing barrier. The three-layer sealing structure of housing seam sealing, wiring hole sealing and external interface sealing works together to form the whole machine sealing protection system, which can effectively prevent liquid and solid impurities such as rainwater, mud, dust, and oil from seeping into the internal cavity of the housing from the three gaps of housing seam, internal wiring channel and external power supply interface. When the equipment is working normally, the multiple sets of lithium iron phosphate battery packs arranged inside the battery module 3 continuously output DC power, and the power is stably conducted to the control module 5 in the main control compartment through the soft connection component 6.Control module 5 has built-in voltage, current, and temperature acquisition and detection circuits, which synchronously collect three sets of operating parameters in real time: the output voltage of battery module 3, the circuit operating current, and the cell surface temperature. When overvoltage, overcurrent, or overtemperature abnormal conditions are detected, the internal protection circuit of control module 5 quickly cuts off the output circuit, realizing multiple safety protections against overload, overtemperature, and overvoltage. The electrical energy after regulation and protection is delivered outward through the positive and negative electrode output posts vertically penetrating the top surface of the upper housing 2. Annular waterproof gaskets are installed at the contact positions between the positive and negative electrode output posts and the through holes of the upper housing 2. The gaskets tightly wrap around the outer wall of the electrodes, sealing the electrodes from the housing. The small gaps between the electrodes prevent liquids and dust from seeping into the main control compartment along the electrode assembly seams. When the equipment malfunctions and needs repair, only the lower housing 1 and upper housing 2 need to be disassembled and reassembled to open the main housing. The battery compartment and main control compartment do not have any locking clips, fastening bolts, or other limiting structures. Battery module 3 and control module 5 are independent, standardized, and modular units. Operators do not need any special disassembly tools; they can remove each module individually from its corresponding compartment by hand to replace the faulty module, without disassembling and scrapping the entire unit. This design prevents the rigid transmission of vehicle-borne vibrations to internal components, avoids relative displacement of modules pulling on solder joints, electrode solder joint detachment, circuit breakage, and cell displacement and damage from impacts, improves the overall shock and impact resistance of the unit, meets vehicle vibration standards, ensures stable power supply operation under complex vehicle road conditions, and significantly reduces the probability of electrical faults caused by vibration.
