Description

Technical Field

[0001] This invention relates to the field of battery swapping connectors for heavy-duty trucks, and more particularly to a battery swapping connector for a heavy-duty truck battery swapping pack with a heating device. Background Technology

[0002] With the increasing emphasis on environmental protection by the government, pure electric vehicles, as a new energy vehicle product, have been promoted in the market for many years and represent the future development direction of the automotive industry. Current battery-swapping heavy-duty trucks adopt a backpack-style battery pack structure where the battery is separated from the vehicle: the battery is assembled inside the upper frame, while the battery swapping connector, protective components, and other parts are mounted on the base. The base is rigidly connected to the vehicle frame by bolts. When the vehicle is in normal operation, the upper battery frame is connected to the base via a lock. Because the base is fixed to the vehicle frame, the battery pack can be stably installed on the vehicle chassis. Current is transmitted to the vehicle through the battery swapping connector on the base, providing power for vehicle operation. In this backpack-style structure, both the upper battery pack frame and the base are mounted on the frame behind the cab, and are exposed to the natural environment for extended periods.

[0003] In practical applications, battery swapping connectors for pure electric heavy-duty trucks are susceptible to damage from mud, rain, and frost, leading to functional failure. Especially during battery swapping, the connector's metal contacts experience a surge in contact resistance due to frost and ice. Furthermore, the following key defects exist: the high-voltage terminals of the battery swapping connector plug are connected to the cable lugs via bolts, leaving the connection exposed. Due to frost, water, and ice, insulation performance deteriorates, posing a risk of electric shock. Additionally, traditional battery swapping connector plugs have low IP protection levels, failing to effectively resist rain and dust intrusion, easily leading to corrosion of internal components and affecting normal connector operation. The battery pack structure is prone to water seepage; moisture penetration reduces the insulation performance of the battery swapping connector, causing vehicle insulation failure and affecting normal vehicle use. Therefore, a battery swapping connector with a heating device for heavy-duty truck battery packs is proposed to address these issues. Summary of the Invention

[0004] To overcome the above deficiencies, the present invention provides a battery swapping connector for a heavy-duty truck battery swapping pack with a heating device, aiming to solve the problems of easy frost or ice formation, low protection level, and poor insulation performance of the existing heavy-duty truck battery swapping connector in low-temperature environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery swapping connector for a heavy-duty truck battery swapping pack with a heating device, comprising a battery swapping connector body, wherein a PDC constant temperature module mounting slot is provided on the battery swapping connector body, and an insulating sealing component is provided on the battery swapping connector body; a protective shell, wherein the protective shell is bolted to the battery swapping connector body; a constant temperature heating module and a waterproof plug, wherein the constant temperature heating module and the waterproof plug are both fixedly connected in the PDC constant temperature module mounting slot; and a temperature sensor, wherein the temperature sensor is fixedly connected to the battery swapping connector body.

[0006] Preferably, the battery swapping connector body includes a base, a socket, and a plug. The surface of the base is fixedly connected to the protective shell by bolts, the socket is fixedly connected to the base, and the plug is fixed to the socket.

When the temperature sensor detects that the contact temperature is ≤0℃, the controller triggers the constant temperature heating module to start running at maximum power to quickly heat up and defrost. S2. When the contact temperature rises to the 60-70℃ range, the controller controls the constant temperature heating module to switch to dry-burning power constant temperature operation to maintain the contact temperature above the freezing point. S3. When the vehicle is in battery swapping mode, the electronic control unit sends a battery swapping signal to the controller, and the controller keeps the constant temperature heating module running. S4. When the constant temperature heating module malfunctions, the controller sends a fault signal to the vehicle's electronic control unit.

[0008] Preferably, the maximum starting power of the constant temperature heating module is set to 15W, and the dry-burning power of the constant temperature heating module is set to 2W.

[0009] Preferably, the insulating sealing assembly includes a sealing gasket and an insulating sleeve, the sealing gasket being fixedly connected to the socket, the insulating sleeve being fixedly connected to the sealing gasket, and the insulating sleeve being fitted onto the plug.

[0010] Preferably, the socket has a contact groove cavity inside, and multiple metal contacts are fixedly connected in the contact groove cavity. One end of the plug passes through the socket and is located in the contact groove cavity.

[0011] Preferably, the constant temperature heating module is located inside the socket, the waterproof plug is located above the constant temperature heating module, and is used to seal and protect the constant temperature heating module in the PDC constant temperature module mounting slot. The temperature sensor is sleeved on the plug and is used to monitor the temperature of the metal contacts.

[0013] Preferably, the base is provided with a floating mechanism assembly, which includes a mounting ring fixedly connected to the base.

[0014] Preferably, the ends of the movable docking seat and the floating base are fixedly connected to the ends of the two sets of springs, respectively.

[0015] The present invention has the following beneficial effects: 1. In this invention, by setting a constant temperature heating module in the PDC constant temperature module mounting slot, the battery swapping connector body can be heated in a low-temperature environment, so that the battery swapping connector body is maintained within a stable operating temperature range. This effectively avoids the problem of increased contact resistance due to low temperature, ensures power transmission efficiency and stability, and can specifically solve the problem of frost or ice formation on connector contacts, avoiding low-temperature contact failures. Compared with traditional heating methods, the temperature control is more precise and the energy consumption is lower.

[0017] 3. In this invention, the guide tube cooperates with the guide post on the battery pack during the battery swapping docking process. The guide tube can play a precise guiding role during the docking of the battery swapping connector with the battery pack or vehicle, reducing docking difficulty and improving battery swapping connection efficiency. The low-voltage power supply interface is electrically connected to the constant temperature heating module and temperature sensor through wires, respectively, to provide low-voltage working power for electrical components such as the constant temperature heating module and temperature sensor.

[0018] 4. In this invention, the floating mechanism assembly, through the elastic action of the spring and the sliding connection between the movable docking seat and the floating base, can effectively compensate for horizontal or angular deviations during the battery swapping docking process, buffer the vibration and impact generated by vehicle driving or battery swapping operations, avoid component damage caused by hard contact, and improve connection reliability and service life.

[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] Reference Figures 1-4 The present invention provides an embodiment of a battery swapping connector for a heavy-duty truck battery swapping pack with a heating device, comprising a connector body 1, a PDC constant temperature module mounting slot 4 on the connector body 1, an insulating sealing component 3 on the connector body 1 to improve the sealing and insulation performance of the connector; a protective shell 2, which is bolted to the connector body 1 and provides collision and corrosion protection for the connector body 1; a constant temperature heating module 5 and a waterproof plug 6. All components are fixedly connected in the PDC constant temperature module mounting slot 4. The constant temperature heating module 5 is used to realize the low-temperature heating and constant temperature function. The constant temperature heating module 5 adopts a 24V constant temperature PDC heating element and a constant temperature control of 70℃. It can specifically solve the problem of frost or ice formation on the connector contacts and avoid low-temperature contact failure. Compared with traditional heating methods, the temperature control is more accurate and the energy consumption is lower. The waterproof plug 6 is made of rubber and is used to seal and protect the constant temperature heating module 5 in the PDC constant temperature module mounting slot 4 to prevent moisture from entering. The temperature sensor 7 is fixedly connected to the battery swapping connector body 1.

[0023] Reference Figures 5-6 The battery swapping connector body 1 includes a base 11, a socket 12, and a plug 13. The bottom of the protective shell 2 is connected to the base 11 by bolts, and waterproof sealant is applied to the connection surface to form a protective space inside the protective shell 2, effectively resisting the intrusion of rainwater and dust, and meeting the protection requirements in harsh environments. The socket 12 is fixedly connected to the base 11, and the plug 13 is fixed to the socket 12. The constant temperature heating module 5 is glued and fixed inside the socket 12 with thermal conductive adhesive, and the constant temperature heating module 5 is tightly fitted to the inner wall of the socket 12 to improve heat conduction efficiency. The waterproof plug 6 is fixed to the opening of the PDC constant temperature module mounting slot 4 by threaded connection, located above the constant temperature heating module 5, to achieve sealed protection for the constant temperature heating module 5.

[0024] Reference Figure 8 A controller is installed on the constant temperature heating module 5, and an electronic control unit is installed on the base 11. The controller is communicatively connected to the constant temperature heating module 5, the temperature sensor 7, and the electronic control unit. The control logic is as follows: S1. When the temperature sensor 7 detects that the contact temperature is ≤0℃, the controller triggers the constant temperature heating module 5 to start running at the maximum power of 15W to quickly heat up and defrost, so as to avoid contact failure caused by contact freezing at low temperature. S2. When the contact temperature rises to the range of 60-70℃, the controller controls the constant temperature heating module 5 to switch to the dry-burning power of 2W for constant temperature operation, maintaining the contact temperature above the freezing point to prevent frost and reduce energy consumption. S3. When the vehicle is in battery swapping mode, the electronic control unit sends a battery swapping signal to the controller. The controller keeps the constant temperature heating module 5 running to ensure that the contacts do not freeze during the battery swapping process and to ensure that the battery swapping operation is carried out smoothly. S4. When the constant temperature heating module 5 malfunctions, the controller sends a fault signal to the vehicle's electronic control unit and provides an alarm notification through the instrument panel to ensure safe use and comply with the technical standards for fault warning in commercial vehicles.

[0025] Reference Figure 5 The insulating sealing assembly 3 includes a sealing gasket 31 and an insulating sleeve 32. The sealing gasket 31 is fixedly connected to the socket 12 and is made of nitrile rubber. It is placed between the protective shell 2 and the base 11 to further enhance waterproof performance. The insulating sleeve 32 is fixedly connected to the sealing gasket 31 and is fitted onto the plug 13. The insulating sleeve 32 is made of silicone rubber with a temperature resistance of 125℃ and is fitted onto the bolt connection between the plug 13 of the power swapping connector and the cable lug, thus avoiding exposed metal and solving the problem of traditional connection points lacking electric shock protection. By setting the insulating sealing assembly 3, which consists of the sealing gasket 31 and the insulating sleeve 32, the sealing gasket 31 can achieve a sealed connection between the socket 12 and external components. The insulating sleeve 32, fitted onto the plug 13, can enhance the insulation performance of the plug 13 and further improve the sealing performance at the connection between the plug 13 and the socket 12, effectively preventing external moisture, dust, and other impurities from entering the connector and avoiding the risk of short circuit. The protective shell 2 works in conjunction with the insulating sealing component 3 to achieve sealed protection. The insulating sleeve 32 and the sealant further enhance the insulation performance, solving the problem of reduced insulation caused by water seepage into the battery pack grid, which meets the protection requirements of the mining truck's rear battery box structure.

[0026] Reference Figure 6The socket 12 has a contact groove 14 inside, and multiple metal contacts 15 are fixedly connected in the contact groove 14. A temperature sensor 7 is sleeved on the plug 13, which can directly monitor the temperature of the metal contacts 15 in real time, so that the background control system can keep track of the connector's working temperature status. When the temperature is abnormal, the working status of the constant temperature heating module 5 can be adjusted in time or an early warning signal can be issued, further improving the safety of the battery swapping process. One end of the plug 13 passes through the socket 12 and is located in the contact groove 14. By setting the constant temperature heating module 5 in the PDC constant temperature module mounting slot 4, the socket 12 and the internal metal contacts 15 can be heated in a low-temperature environment, so that the metal contacts 15... Maintaining a stable operating temperature range effectively avoids the problem of increased contact resistance due to low temperatures, ensuring power transmission efficiency and stability. Simultaneously, the constant temperature heating module 5 has self-limiting temperature characteristics, eliminating the need for an additional temperature control switch, preventing overheating damage and improving safety. The temperature sensor 7, mounted on the plug 13, monitors the temperature of the metal contacts 15 in real time, allowing the backend control system to promptly grasp the connector's operating temperature status. When abnormal temperatures occur, the operating status of the constant temperature heating module 5 can be adjusted promptly or an early warning signal can be issued, further enhancing the safety of the battery swapping process.

[0027] Reference Figure 6 Two sets of symmetrically distributed guide tubes 17 are fixedly connected to the base 11. The inner wall of the guide tube 17 is provided with guide grooves, which can cooperate with the guide posts on the battery pack during the battery swapping docking process. The guide tubes 17 can play a precise guiding role during the docking of the battery swapping connector with the battery pack or vehicle, reducing docking difficulty and improving battery swapping connection efficiency. A low-voltage power supply interface 16 is fixedly connected to the base 11. The low-voltage power supply interface 16 is electrically connected to the constant temperature heating module 5 and the temperature sensor 7 through wires, respectively, to provide low-voltage working power to electrical components such as the constant temperature heating module 5 and the temperature sensor 7.

[0028] Reference Figure 7A floating mechanism assembly 8 is provided on the base 11. The floating mechanism assembly 8 includes a mounting ring 81, a movable docking seat 82, a limiting guide rod 83, a floating base 84, and springs 85. The mounting ring 81 is fixedly connected to the base 11. The movable docking seat 82 is slidably connected to one end of the mounting ring 81 and is in direct contact with the battery swapping docking end. The limiting guide rod 83 is fixedly connected to the other end of the mounting ring 81 and serves as a guide and limit. The floating base 84 is slidably sleeved on the limiting guide rod 83 and can slide along the axial direction of the guide rod. Both ends of the mounting ring 81 are fixedly connected to springs 85 by welding. The ends of the movable docking seat 82 and the floating base 84 are respectively fixedly connected to the ends of two sets of springs 85. During the battery swapping process, if there is an installation deviation or vibration impact, the movable docking seat 82 can slide along the mounting ring 81, and the floating base 84 can slide along the limiting guide rod 83. The two sets of springs 85 undergo elastic deformation to generate buffer force, thereby compensating for deviations in the horizontal direction and angle, avoiding damage from hard contact between the plug 13 and the docking end, and ensuring connection stability. After the docking is completed, the springs 85 reset, driving the movable docking seat 82 and the floating base 84 back to their initial positions to ensure connection accuracy.

[0029] Working principle: The battery swapping connector socket 12 is fixed to the mounting base of the base 11 with bolts, ensuring that the socket 12 and the base 11 are perpendicular to avoid installation deviation affecting the connection. The plug 13 is connected to the cable lug in the upper frame of the battery pack with bolts. After connection, a silicone rubber insulating sleeve 32 is fitted at the bolt. Thermal conductive silicone is applied to the contact surface of the constant temperature heating module 5 and it is attached to the outer wall of the contact seat of the battery swapping connector socket 12 to ensure that the module and the contact seat are in close contact and improve the heat conduction efficiency. The constant temperature heating module 5 is connected to the low voltage power supply interface 16 on the base 11 through a waterproof terminal to ensure the waterproofness of the wiring connection.

[0030] When the ambient temperature is low, the low-voltage power supply interface 16 supplies power to the constant temperature heating module 5. The constant temperature heating module 5 generates heat and transfers it to the socket 12 and the metal contacts 15, heating the metal contacts 15 to maintain them at a suitable operating temperature and prevent increased contact resistance due to low temperature. The temperature sensor 7 monitors the temperature of the metal contacts 15 in real time and transmits the temperature signal to the background control system. When the temperature exceeds the set threshold, the background control system can control the constant temperature heating module 5 to stop heating; when the temperature is below the set threshold, it can control the constant temperature heating module 5 to start heating, achieving constant temperature regulation. The sealing gasket 31 and insulating sleeve 32 in the insulation sealing assembly 3 can effectively prevent external moisture and dust from entering the connector, ensuring the sealing and insulation performance of the connector and improving safety. In this technical solution, the components are connected by bolts, adhesives, etc., without the need for complex tooling, which facilitates assembly on the production line and after-sales maintenance, reducing production and maintenance costs. The constant temperature heating module 5 has constant temperature control, overcurrent protection and fault alarm functions, and meets the requirements of protection against electric shock, high insulation and high protection, which comply with the safety technical standards for commercial vehicles.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
