Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically a fixing flange for a cooler in a new energy bus. Background Technology

[0002] Against the backdrop of global advocacy for energy conservation and emission reduction, new energy buses have gradually become the main force in the public transportation sector due to their obvious advantages of low emissions and high efficiency. As a key component of new energy buses, the cooling system is directly related to the vehicle's power performance, safety, and service life. As the core connecting component of the cooler, the performance of the fixed flange plays a decisive role in whether the cooling system can operate stably.

[0003] The fixed flanges used in traditional fuel-powered bus coolers have revealed numerous problems when adapted to new energy buses. Because the batteries and motors of new energy buses generate a large amount of heat during operation, the working pressure and temperature of their cooling systems are significantly higher than those of traditional fuel-powered buses. The materials and structures of traditional fixed flanges are insufficient to withstand this, leading to decreased sealing performance and an increased risk of coolant leakage. Once coolant leaks, not only will cooling efficiency be reduced, but in severe cases, it may even cause a battery short circuit, posing a significant threat to driving safety. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing flange for the cooler of a new energy bus, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing flange for a cooler of a new energy bus, including a first auxiliary frame, a connecting mechanism provided inside the first auxiliary frame, and a second auxiliary frame provided around the connecting mechanism;

[0006] The connecting mechanism includes a flange body, which is fixedly connected to the inner side of the first auxiliary frame. A limit pin is threadedly connected to the left side of the flange body, a gasket is slidably connected to the periphery of the limit pin, and a nut is threadedly connected to the periphery of the limit pin. A slide rod is fixedly connected inside the flange body, and a first moving block is slidably connected to the periphery of the slide rod. A first sealing ring is fixedly connected to the left side of the first moving block and slidably connected to the inner side of the flange body. A second moving block is slidably connected to the periphery of the slide rod, and a second sealing ring is fixedly connected to the right side of the second moving block and slidably connected to the inner side of the flange body. A spring is sleeved around the periphery of the slide rod.

[0007] Preferably, the left side of the spring is fixedly connected to the right side of the first moving block, the right side of the spring is fixedly connected to the left side of the second moving block, and the flange body is fixedly connected to the inner side of the second auxiliary frame, so as to ensure the stability of the first sealing ring and the second sealing ring under the action of the spring.

[0008] Preferably, there are two sets of the first moving block, slide rod, spring and second moving block. The two sets of the first moving block, slide rod, spring and second moving block are symmetrically distributed on the upper and lower sides of the flange body, and the two sets of the first moving block and the second moving block are respectively distributed on the right side of the first sealing ring and the left side of the second sealing ring. By setting two sets, the stability of the first sealing ring and the second sealing ring can be further guaranteed.

[0009] Preferably, the outer peripheries of the first and second sealing rings are in contact with the inner side of the flange body, and both the first and second sealing rings are made of heat-resistant and corrosion-resistant materials, so that the first and second sealing rings can improve the sealing effect when the cooler is connected to the flange body or when the flange body is connected to other pipes.

[0010] Preferably, the limiting pins, washers, and nuts are provided in two sets, and the two sets of limiting pins, washers, and nuts are symmetrically distributed on the left and right sides of the flange body, so as to facilitate the fixing of the cooler and other pipes to the flange body under the action of the limiting pins.

[0011] Preferably, the flange body includes a sealing layer, a high-temperature resistant layer is fixedly connected to the periphery of the sealing layer, a shock-absorbing layer is fixedly connected to the periphery of the high-temperature resistant layer, and a corrosion-resistant layer is fixedly connected to the periphery of the shock-absorbing layer.

[0012] Preferably, the sealing layer is the innermost layer, which is made of fluororubber material, and the corrosion-resistant layer is the outermost layer, which is made of aluminum alloy material, so as to improve the service life and quality of the flange body under the action of the corrosion-resistant layer.

[0013] Compared with the prior art, this utility model provides a fixing flange for the cooler of a new energy bus, which has the following advantages:

[0014] 1. The cooling unit fixing flange of this new energy bus uses a connection mechanism. When the cooling unit needs to be fixed, the limit pin, nut, and gasket are first removed. The connection part of the cooling unit is then brought into contact with the left side of the flange body, corresponding to the through hole inside the flange body. When the connection part is in contact with the flange body, it compresses the first sealing ring, causing the first sealing ring to drive the first moving block to slide around the slide rod, and causing the spring to deform. At the same time, the first sealing ring and its outer periphery are always in contact with the inner side of the flange body, ensuring the stability and sealing effect of the connection between the cooling unit and the flange body. Even if the cooling unit vibrates during operation, the elastic deformation of the spring can ensure that the sealing ring maintains a good sealing state, effectively preventing coolant leakage and ensuring the efficient and stable operation of the cooling system. When the connection is completed, the flange body and the cooling unit can be fixed by the limit pin, nut, and gasket, making it convenient for users to install and disassemble.

[0015] 2. The fixed flange of the cooler in this new energy bus is constructed with a sealing layer, a high-temperature resistant layer, a shock-absorbing layer, and a corrosion-resistant layer, made of fluororubber, high-temperature alloy, natural rubber, and aluminum alloy, respectively. The shock-absorbing layer effectively absorbs the vibration and impact generated during the operation of the cooler, reducing its impact on other components of the bus and extending the service life of the cooler and related parts, while also reducing noise caused by vibration. The high-temperature resistant layer effectively resists the effects of high-temperature environments on the flange, ensuring that it maintains good mechanical properties and structural stability under high-temperature conditions. The outermost corrosion-resistant layer is made of aluminum alloy, which not only effectively prevents corrosion of the flange by coolant, air, and other media, extending the product's service life, but also reduces the product's weight, meeting the lightweight design requirements of new energy buses. Furthermore, the sealing layer ensures good sealing between the fixed flange body and the cooler and bus connections, preventing coolant leakage. Attached Figure Description

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-5 This utility model provides a technical solution: a fixing flange for a cooler of a new energy bus, including a first auxiliary frame 1, a connecting mechanism 2 is provided inside the first auxiliary frame 1, and a second auxiliary frame 3 is provided around the connecting mechanism 2;

[0028] The connecting mechanism 2 includes a flange body 21, which is fixedly connected to the inner side of the first auxiliary frame 1. A limit pin 22 is threadedly connected to the left side of the flange body 21. A gasket 23 is slidably connected to the periphery of the limit pin 22. A nut 24 is threadedly connected to the periphery of the limit pin 22. A slide rod 27 is fixedly connected inside the flange body 21. A first moving block 25 is slidably connected to the periphery of the slide rod 27. A first sealing ring 26 is fixedly connected to the left side of the first moving block 25. The first sealing ring 26 is slidably connected to the inner side of the flange body 21. A second moving block 29 is slidably connected to the periphery of the slide rod 27. A second sealing ring 291 is fixedly connected to the right side of the second moving block 29. The second sealing ring 291 is slidably connected to the inner side of the flange body 21. A spring 28 is sleeved around the periphery of the slide rod 27.

[0029] The left side of spring 28 is fixedly connected to the right side of the first moving block 25, and the right side of spring 28 is fixedly connected to the left side of the second moving block 29. The flange body 21 is fixedly connected to the inner side of the second auxiliary frame 3, so as to ensure the stability of the first sealing ring 26 and the second sealing ring 291 under the action of spring 28. There are two sets of the first moving block 25, slide rod 27, spring 28 and second moving block 29. The two sets of the first moving block 25, slide rod 27, spring 28 and second moving block 29 are symmetrically distributed on the upper and lower sides of the flange body 21, and the two sets of the first moving block 25 and the second moving block 29 are respectively distributed on the right side of the first sealing ring 26 and the left side of the second sealing ring 291. By setting two sets, the stability of the first sealing ring 26 and the second sealing ring 291 can be further guaranteed.

[0030] The outer periphery of the first sealing ring 26 and the second sealing ring 291 respectively contact the inner side of the flange body 21. Both the first sealing ring 26 and the second sealing ring 291 are made of heat-resistant and corrosion-resistant materials, which can improve the sealing effect when the cooler is connected to the flange body 21 or when the flange body 21 is connected to other pipes. Two sets of limit pins 22, gaskets 23 and nuts 24 are provided. The two sets of limit pins 22, gaskets 23 and nuts 24 are symmetrically distributed on the left and right sides of the flange body 21, which can facilitate the fixing of the cooler and other pipes to the flange body 21 under the action of the limit pins 22.

[0031] Example 2

[0032] Please see Figure 1-5 Furthermore, based on Embodiment 1, the flange body 21 further includes a sealing layer 4, a high-temperature resistant layer 5 fixedly connected to the periphery of the sealing layer 4, a shock-absorbing layer 6 fixedly connected to the periphery of the high-temperature resistant layer 5, and a corrosion-resistant layer 7 fixedly connected to the periphery of the shock-absorbing layer 6. The sealing layer 4 is the innermost layer and is made of fluororubber material. The corrosion-resistant layer 7 is the outermost layer and is made of aluminum alloy material, which facilitates the improvement of the service life and quality of the flange body 21 under the action of the corrosion-resistant layer 7.

[0033] In actual operation, when this device is used and the cooler of a new energy bus needs to be fixed, first remove the limit pin 22, nut 24, and washer 23. Then, align the cooler connection part with the left side of the flange body 21, aligning it with the through hole inside the flange body 21. When the connection part contacts the flange body 21, it compresses the first sealing ring 26, causing the first sealing ring 26 to drive the first moving block 25 to slide around the slide rod 27, and causing the spring 28 to deform. Simultaneously, the first sealing ring 26 and its outer periphery remain in contact with the inner side of the flange body 21, ensuring the stability and sealing effect of the connection between the cooler and the flange body 21. Even if the cooler vibrates during operation, the elastic deformation of the spring 28 ensures that the sealing ring maintains a good seal, effectively preventing coolant leakage and ensuring the efficient and stable operation of the cooling system.

[0034] When the connection is complete, the nut 24 can be threaded onto the periphery of the limiting pin 22, and the washer 23 can be slidably connected to the periphery of the limiting pin 22. At the same time, the limiting pin 22 is threaded onto the cooler connection part and the inside of the flange body 21. Then tighten the nut 24 to quickly complete the connection with the cooler or other components. The washer 23 and the nut 24 can evenly distribute the force on the connection part, making the connection more secure and reliable, and reducing the risk of loosening due to vibration or external force. When the flange body 21 needs to be connected to other pipes, it is also first contacted with the right side of the flange body 21 and the second sealing ring 291 is squeezed. When the connection is complete, it is fixed by the limiting pin 22, nut 24 and washer 23 on the right side of the flange body 21, which is convenient for users to install and disassemble. During installation, the first auxiliary frame 1 and the second auxiliary frame 3 can be held to support the flange body 21, which improves the convenience of installation.

[0035] The flange body 21 is constructed with a sealing layer 4, a high-temperature resistant layer 5, a shock-absorbing layer 6, and a corrosion-resistant layer 7, made of fluororubber, high-temperature alloy, natural rubber, and aluminum alloy, respectively. The shock-absorbing layer 6 effectively absorbs the vibration and impact generated during the operation of the cooler, reducing its impact on other components of the bus and extending the service life of the cooler and related components, while also reducing noise caused by vibration. The high-temperature resistant layer 5 effectively resists the impact of high-temperature environments on the flange, ensuring that it maintains good mechanical properties and structural stability under high-temperature conditions. The outermost corrosion-resistant layer 7 is made of aluminum alloy, which not only effectively prevents the flange from being corroded by media such as coolant and air, extending the product's service life, but also reduces the product's weight, meeting the lightweight design requirements of new energy buses. Furthermore, the sealing layer 4 ensures good sealing at the connection between the flange body 21 and the cooler and the bus, preventing coolant leakage.
