Description

Technical Field

[0001] This utility model relates to the field of methanol range extender technology, and in particular to a quick connection and cooling interface device for a methanol range extender. Background Technology

[0002] A methanol range extender is a range-extending power device that uses methanol as fuel and generates electricity through an internal combustion engine to replenish the power battery. Its core value lies in balancing range, cost, and environmental protection requirements, and it shows significant advantages, especially in commercial vehicles, logistics vehicles, and mining trucks. The quick connection and cooling interface device of the methanol range extender is a key design element for improving system reliability and maintenance efficiency.

[0003] Existing technologies for quick connections in methanol fuel lines must meet requirements for corrosion resistance, sealing, and rapid insertion / removal. MANTECO's dry quick-connect couplings designed for marine methanol refueling systems employ a double-sealing structure and an emergency break valve to achieve leak-free connections. Applications of this type of coupling in the automotive field can refer to the SAE J2044 standard. However, methanol has a high latent heat of vaporization, easily forming liquid deposits in environments below -20°C, leading to difficulties in cold starts. Currently, electro-liquid heaters are used to dynamically adjust the target coolant temperature based on ambient temperature. However, long-term use causes the inner wall of the interface to thin, and vibrations during vehicle operation can cause the coupling to loosen and detach at the connection point, resulting in seal failure. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a quick connection and cooling interface device for a methanol range extender, which aims to improve the problems in the prior art where long-term use leads to thinning of the inner wall of the interface, and vibration during vehicle operation causes the connector and socket connection to loosen and fall off, resulting in sealing failure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick connection and cooling interface device for a methanol range extender, comprising a housing, a methanol engine mounted on the left side of the inner wall of the housing, a fixing mechanism mounted on the front side of the outer wall of the methanol engine to prevent components from falling off, multiple fixing plates equidistantly fixed to the front side of the outer wall of the methanol engine, a vibration damping mechanism mounted at the front end of the fixing plates to reduce the vibration impact on the components; the fixing mechanism includes fixing plates equidistantly fixed to the front side of the outer wall of the methanol engine, a connector mounted on the outer wall of the methanol engine, slots provided at the upper and lower ends of the outer wall of the connector, a rotating shaft rotatably connected to the right side of the front end of the outer wall of the fixing plate, a limiting plate rotatably connected to the outer wall of the rotating shaft, the limiting plate slidably connected to the inner wall of the slot, and a drive assembly mounted on the left side of the inner wall of the fixing plate.

[0006] As a further description of the above technical solution:

[0007] The drive assembly includes a pull rod, which is slidably connected to the left side of the inner wall of the fixed plate. A fixed rod is fixedly connected to the middle of the outer wall of the pull rod, and a spring is installed on the outer wall of the pull rod.

[0008] As a further description of the above technical solution:

[0009] A limit rod is installed at the end of the pull rod, and the limit rod is slidably connected to the inner wall of the limit plate.

[0010] As a further description of the above technical solution:

[0011] The vibration damping mechanism includes a base, which is fixedly connected to the front side of the outer wall of the fixed plate. A damping rod is installed in the middle of the top wall of the base, and a long plate is installed at the top of the damping rod.

[0012] As a further description of the above technical solution:

[0013] The bottom wall of the long plate is rotatably connected to both the left and right sides, and the inner wall of the crank is rotatably connected to a slider.

[0014] As a further description of the above technical solution:

[0015] A second spring is installed on the outer wall of the slider, and the slider is slidably connected to the inner wall of the base.

[0016] As a further description of the above technical solution:

[0017] A control module is installed on the top wall of the housing, and a connecting pipe is installed at one end of the connector.

[0018] As a further description of the above technical solution:

[0019] A generator is installed at the end of the connecting pipe, and the generator is fixedly connected to the right side of the inner wall of the outer casing.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, after the connector is inserted into the socket on the outer wall of the methanol engine, the pull rod is pulled. The pull rod drives the limiting rod to move to the left on the inner wall of the fixing plate. At the same time, the fixing rod on the outer wall of the pull rod will compress the spring. After reaching the designated position, the limiting plate is moved. The limiting plate rotates along the pivot, so that the limiting plate is inserted into the slot on the outer wall of the connector. At the same time, the limiting rod slides into the inner side of the limiting plate along the opening of the limiting plate. The pull rod is released, and the spring rebounds and pushes against the fixing rod, so that the fixing rod pushes the pull rod, so that the limiting rod is locked into the inner wall of the limiting plate, forming a stable connection. This prevents the inner wall of the interface from thinning due to long-term use, and prevents the connector from loosening and falling off due to vibration during vehicle operation, resulting in sealing failure.

[0022] 2. In this utility model, when the equipment vibrates, the vibration force is transmitted to the base through the fixed plate, while the vibration generated by the methanol engine is transmitted to the long plate through the joint. The long plate compresses the damping rod, and then transmits the crank. The crank compresses the slider, pushes the slider to slide in the base and compress the second spring. When the second spring is subjected to vibration, it undergoes elastic deformation. Through the damping rod and the contraction of the second spring, the vibration energy is absorbed and buffered, enabling the equipment to adapt to the vibration frequency, further improving the structure's vibration resistance, avoiding loosening, wear or even damage of parts due to long-term vibration, and extending the service life of the equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a quick connection and cooling interface device for a methanol range extender, including a housing 1. A methanol engine 2 is installed on the left side of the inner wall of the housing 1. The methanol engine 2 is a Yuchai YCK06H, with a displacement of 2.8L, a compression ratio of 16.5:1, and a thermal efficiency of 42%. A fixing mechanism 3 is installed on the front side of the outer wall of the methanol engine 2 to prevent components from falling off. Multiple fixing plates 8 are equidistantly fixed to the front side of the outer wall of the methanol engine 2. A vibration damping mechanism 4 is installed at the front end of the fixing plates 8 to reduce the vibration impact on the components. The fixing mechanism 3 includes fixing pieces 301, which are equidistantly fixed to the front side of the outer wall of the methanol engine 2. A connector 305 is installed on the outer wall. Slots 304 are provided at the upper and lower ends of the outer wall of the connector 305. A rotating shaft 302 is rotatably connected to the right front end of the outer wall of the fixing plate 301. A limiting plate 303 is rotatably connected to the outer wall of the rotating shaft 302. The limiting plate 303 is slidably connected to the inner wall of the slot 304. A drive assembly 307 is installed on the left side of the inner wall of the fixing plate 301. The drive assembly 307 includes a pull rod 3071. The pull rod 3071 is slidably connected to the left side of the inner wall of the fixing plate 301. A fixing rod 3073 is fixedly connected to the middle of the outer wall of the pull rod 3071. A spring 3072 is installed on the outer wall of the pull rod 3071. A limiting rod 306 is installed at the end of the pull rod 3071. The limiting rod 306 is slidably connected to the inner wall of the limiting plate 303.

[0032] Specifically, after inserting connector 305 into the socket on the outer wall of methanol engine 2, pull rod 3071. Pull rod 3071 causes limiting rod 306 to move to the left on the inner wall of fixing plate 301. At the same time, fixing rod 3073 on the outer wall of pull rod 3071 compresses spring 3072. After reaching the designated position, move limiting plate 303. Limiting plate 303 rotates along rotating shaft 302, causing limiting plate 303 to insert into slot 304 on the outer wall of connector 305. Simultaneously, limiting rod 306 slides into the inner side of limiting plate 303 along the opening of limiting plate 303. Release the pull rod 3071, and the spring 3072 will rebound and press against the fixing rod 3073, causing the fixing rod 3073 to push the pull rod 3071, allowing the limiting rod 306 to engage with the inner wall of the limiting plate 303, forming a stable connection. This prevents the connector 305 from loosening and falling off at the connection point with the socket, which could lead to sealing failure. When it is necessary to remove the connector 305, pull the pull rod 3071 again. The pull rod 3071 will move the limiting rod 306 to the designated position. Rotate the limiting plate 303 to slide it out of the slot 304, and then the connector 305 can be removed. The operation is convenient.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The vibration damping mechanism 4 includes a base 405, which is fixedly connected to the front side of the outer wall of the fixed plate 8. A damping rod 406 is installed in the middle of the top wall of the base 405. A long plate 401 is installed at the top of the damping rod 406. Cranks 402 are rotatably connected to the left and right sides of the bottom wall of the long plate 401. A slider 403 is rotatably connected to the inner wall of the crank 402. A spring 404 is installed on the outer wall of the slider 403. The slider 403 is slidably connected to the inner wall of the base 405.

[0034] Specifically, when the equipment vibrates, the vibration force is transmitted to the base 405 through the fixed plate 8, while the vibration generated by the methanol engine 2 is transmitted to the long plate 401 through the joint 305. The long plate 401 compresses the damping rod 406, and then drives the crank 402. The crank 402 compresses the slider 403, pushing the slider 403 to slide within the base 405 and compress the second spring 404. When the second spring 404 is subjected to vibration, it undergoes elastic deformation. Through the contraction of the damping rod 406 and the second spring 404, the vibration energy is absorbed and buffered, enabling the equipment to adapt to the vibration frequency, further improving the structure's vibration resistance, avoiding loosening, wear, or even damage of components due to long-term vibration, and extending the service life of the equipment.

[0035] Reference Figure 1 , Figure 2 and Figure 3The top wall of the outer casing 1 is equipped with a control module 6. The control module 6 uses an Infineon AURIX TC397 chip with a main frequency of 400MHz and supports ASIL-D functional safety level. One end of the connector 305 is equipped with a connecting pipe 5, and the end of the connecting pipe 5 is equipped with a generator 7. The generator 7 uses Huichuan HD2200 with a power of 30kW and an efficiency of 96.8%. The generator 7 is fixedly connected to the right side of the inner wall of the outer casing 1.

[0036] Specifically, the outer shell 1 of the methanol range extender serves as the overall structural carrier, and is made of 1.5mm thick cold-rolled steel plate through stamping. The control module 6 automatically triggers the start command of the methanol engine 2, and adjusts the injection timing of the fuel injector and the speed of the generator 7 to make the output power of the generator 7 match the power demand of the whole vehicle. The connecting pipe 5 is used to stably transmit the mechanical energy output by the methanol engine 2 to the input shaft of the generator 7.

[0037] Working principle: After inserting connector 305 into the socket on the outer wall of methanol engine 2, pull rod 3071. Pull rod 3071 drives limit rod 306 to move to the left on the inner wall of fixing plate 301. At the same time, fixing rod 3073 on the outer wall of pull rod 3071 will compress spring 3072. After reaching the designated position, move limit plate 303. Limit plate 303 rotates along shaft 302, so that limit plate 303 is inserted into slot 304 on the outer wall of connector 305. At the same time, limit rod 306 slides into the inner side of limit plate 303 through the opening of limit plate 303. Release the pull rod 3071, and the spring 3072 will rebound and press against the fixing rod 3073, causing the fixing rod 3073 to push the pull rod 3071, allowing the limiting rod 306 to engage with the inner wall of the limiting plate 303, forming a stable connection. This prevents the connector 305 from loosening and falling off at the connection point with the socket, which could lead to sealing failure. When it is necessary to remove the connector 305, pull the pull rod 3071 again. The pull rod 3071 will move the limiting rod 306 to the designated position. Rotate the limiting plate 303 so that it slides out of the slot 304, allowing the connector 305 to be removed. The operation is convenient.

[0038] When the equipment vibrates, the vibration force is transmitted to the base 405 through the fixed plate 8, while the vibration generated by the methanol engine 2 is transmitted to the long plate 401 through the joint 305. The long plate 401 compresses the damping rod 406, and then drives the crank 402. The crank 402 compresses the slider 403, pushing the slider 403 to slide in the base 405 and compress the second spring 404. When the second spring 404 is subjected to vibration, it undergoes elastic deformation. Through the contraction of the damping rod 406 and the second spring 404, the vibration energy is absorbed and buffered, enabling the equipment to adapt to the vibration frequency, further improving the structure's vibration resistance, avoiding loosening, wear, or even damage of components due to long-term vibration, and extending the service life of the equipment.
