Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, specifically to a spoiler assembly, a gearbox device, and a vehicle. Background Technology

[0002] In the field of transportation equipment, especially electric vehicles, the gearbox, as a key component of the transmission system, directly affects the overall efficiency of the vehicle. The gearbox achieves speed and torque conversion through the meshing of gears, a process accompanied by energy conversion and inevitably generating heat. For example, in electric vehicles, the drive motor converts high speed to the low speed and high torque required by the wheels through the gearbox; the energy loss during this conversion process is mainly released as heat.

[0003] In related technologies, the temperature control of lubrication systems typically relies on internal natural cooling. However, with technological advancements and increasingly demanding vehicle performance requirements, the gear ratio and load-bearing capacity of reduction gearboxes have also increased accordingly. This leads to a tendency for lubricating oil temperature to rise under high-load operating conditions. Excessively high lubricating oil temperature not only accelerates oil aging and reduces its lubrication effect, but can also cause thermal expansion of gears and bearings, resulting in decreased transmission accuracy and efficiency, and in severe cases, even equipment failure. Utility Model Content

[0004] The main objective of this invention is to provide a spoiler assembly, a gearbox device, and a vehicle to solve the problem of excessively high lubricating oil temperature during gearbox operation in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a spoiler assembly is provided, disposed below the gear in a gearbox. The spoiler assembly includes: a spoiler body having an oil-containing cavity and an opening communicating with the oil-containing cavity, the oil-containing cavity being used to contain lubricating oil and the gear, and the opening allowing the gear to enter into the oil-containing cavity; and a heat exchange structure including a heat exchange body, an input section, and an output section, the heat exchange body being disposed within the oil-containing cavity and having a heat exchange channel, the input section and the output section being disposed on the outer surface of the spoiler body and communicating with the heat exchange channel, so that the heat exchange fluid can flow into and out of the heat exchange channel.

[0006] Furthermore, the heat exchange body includes a cover body, which is disposed on the inner wall of the baffle body. The heat exchange channel is located between the cover body and the inner wall of the baffle body. The baffle body is provided with an inlet that connects the input part and the heat exchange channel, and an outlet that connects the output part and the heat exchange channel.

[0007] Furthermore, the spoiler body includes a base plate and a first side plate and a second side plate disposed on both sides of the base plate. The base plate, the first side plate and the second side plate surround to form an oil-containing cavity. An opening is formed between the top of the first side plate and the top of the second side plate. A cover is disposed on the first side plate. An input part and an output part are disposed on the outer surface of the first side plate.

[0008] Furthermore, the heat exchange structure also includes multiple heat-conducting elements that pass through the cover. The heat-conducting elements have a first section located in the heat exchange channel and a second section located in the oil cavity. The second section is spaced apart from the gear.

[0009] Furthermore, the heat-conducting component is made of metal; and / or, the spoiler body and cover are made of plastic.

[0010] Furthermore, the spoiler assembly also includes a switching structure. The base plate has a first through hole. The switching structure is disposed on the base plate and located at the first through hole. The switching structure is used to open or close the first through hole so that the lubricating oil outside the spoiler assembly flows into the oil receiving cavity or blocks the lubricating oil outside the spoiler assembly from flowing into the oil receiving cavity.

[0011] Furthermore, the switching structure includes a mounting shell, a blocking block, and a driving unit. The mounting shell is disposed on the outer surface of the base plate and has a mounting cavity communicating with the first through hole and a second through hole communicating with the mounting cavity. The blocking block and the driving unit are both disposed in the mounting cavity. The blocking block is movably disposed and has a connected state and a blocked state. The driving unit drives the blocking block to switch between the connected state and the blocked state. When the blocking block is in the blocked state, it blocks the first through hole and the second through hole. When the blocking block is in the connected state, it connects the first through hole and the second through hole.

[0012] Furthermore, the mounting cavity extends in the lateral direction and includes a first cavity, a second cavity, and a connecting port connecting the first cavity and the second cavity. The first cavity is connected to a first through hole, and the second cavity is connected to a second through hole. The sealing block is movably disposed in the first cavity or the second cavity. When the sealing block is in the sealing state, the sealing block blocks the connecting port. When the sealing block is in the connecting state, the sealing block opens the connecting port.

[0013] Furthermore, the driving unit includes a temperature-sensitive deformation element and a spring element. The sealing block is disposed in the first cavity, the temperature-sensitive deformation element is located in the second cavity and abuts against the first end of the sealing block, and the spring element is located in the first cavity and abuts against the second end of the sealing block. The temperature-sensitive deformation element has a first volume at a first preset temperature and a second volume at a second preset temperature. The first preset temperature is greater than the second preset temperature, and the first volume is greater than the second volume. When the temperature-sensitive deformation element switches from the second volume to the first volume, the temperature-sensitive deformation element drives the sealing block to move toward the spring element, thereby causing the sealing block to switch to the connected state. When the temperature-sensitive deformation element switches from the first volume to the second volume, the spring element drives the sealing block to move toward the temperature-sensitive deformation element, thereby causing the sealing block to switch to the blocking state.

[0014] According to another aspect of the present invention, a gearbox device is provided, including a housing and gears, a spoiler assembly and lubricating oil disposed in the housing, wherein the input and output parts of the spoiler assembly pass through the housing, and the spoiler assembly is the aforementioned spoiler assembly.

[0015] According to another aspect of the present invention, a vehicle is provided, including a reduction gearbox device, wherein the reduction gearbox device is the reduction gearbox device described above.

[0016] Applying the technical solution of this utility model, the spoiler body has an oil-containing cavity and an opening communicating with the oil-containing cavity. The lower part of the gear can be set in the oil-containing cavity through the opening. The oil-containing cavity can hold lubricating oil. During operation, the gear rotates, and the lower part of the gear can lift the lubricating oil in the oil-containing cavity. The lifted lubricating oil splashes through the opening to various parts of the components in the gearbox, thereby achieving a lubrication effect on various components. Because the spoiler body can isolate the lower part of the gear, the lower part of the isolated gear can only lift the lubricating oil in the oil-containing cavity without agitating the lubricating oil outside the spoiler body, thus ensuring that... During the initial startup of the gearbox, the lower temperature and higher viscosity of the lubricating oil reduce the resistance to gear starting, thus reducing the overall energy consumption of the gearbox. The heat exchanger body is located within the oil chamber and has a heat exchange channel. The inlet and outlet are located on the outer surface of the baffle body and communicate with the heat exchange channel, allowing the heat exchange fluid to flow in and out of the channel. The heat exchange fluid flowing within the channel exchanges heat with the lubricating oil in the oil chamber, thereby cooling the lubricating oil and ensuring it is at a suitable temperature, thus providing better lubrication performance. Therefore, the technical solution of this application effectively solves the problem of excessively high lubricating oil temperature during gearbox operation in related technologies.

[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.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0033] like Figures 1 to 6 As shown, this application provides a spoiler assembly disposed at the lower part of gear 1 in a gearbox. An embodiment of the spoiler assembly of this application includes: a spoiler body 10 and a heat exchange structure 20; the spoiler body 10 has an oil cavity 11 and an opening communicating with the oil cavity 11, the oil cavity 11 is used to contain lubricating oil and gear 1, and the opening allows gear 1 to enter into the oil cavity 11; the heat exchange structure 20 includes a heat exchange main body 21, an input part 22 and an output part 23, the heat exchange main body 21 is disposed in the oil cavity 11 and has a heat exchange channel, the input part 22 and the output part 23 are disposed on the outer surface of the spoiler body 10 and communicate with the heat exchange channel so that the heat exchange fluid can flow into and out of the heat exchange channel.

[0034] Applying the technical solution of this embodiment, the spoiler body 10 has an oil-containing cavity 11 and an opening communicating with the oil-containing cavity 11. The lower part of the gear 1 can be disposed in the oil-containing cavity 11 through the opening. The oil-containing cavity 11 can contain lubricating oil. During operation, when the gear 1 rotates, the lower part of the gear 1 can lift the lubricating oil in the oil-containing cavity 11. The lifted lubricating oil splashes through the opening to various parts of the components in the gearbox, thereby achieving a lubrication effect on each component. Since the spoiler body 10 can isolate the lower part of the gear 1, the lower part of the isolated gear 1 can only lift the lubricating oil in the oil-containing cavity 11 without agitating the lubricating oil outside the spoiler body 10. This reduces the resistance of the lower-temperature, higher-viscosity lubricating oil to the starting of gear 1 during the initial startup of the gearbox, thus reducing the overall energy consumption of the gearbox. The heat exchange body 21 is disposed within the oil chamber 11 and has a heat exchange channel. The input part 22 and the output part 23 are disposed on the outer surface of the baffle body 10 and communicate with the heat exchange channel, allowing the heat exchange fluid to flow in and out of the channel. The heat exchange fluid flowing within the channel can exchange heat with the lubricating oil in the oil chamber 11, thereby cooling the lubricating oil and ensuring it is at a suitable temperature, thus providing better lubrication performance. Therefore, the technical solution of this embodiment effectively solves the problem of excessively high lubricating oil temperature during gearbox operation in related technologies.

[0035] like Figures 1 to 6 As shown, the heat exchange body 21 includes a cover 211, which covers the inner wall of the baffle body 10. The heat exchange channel is located between the cover 211 and the inner wall of the baffle body 10. The baffle body 10 is provided with an inlet connecting the inlet 22 and the heat exchange channel, and an outlet connecting the outlet 23 and the heat exchange channel. Specifically, by covering the inner wall of the baffle body 10, the cover 211 can form a closed heat exchange channel using the inner wall of the baffle body 10, making full use of the structure of the baffle body 10 itself.

[0036] like Figures 1 to 6As shown, the spoiler body 10 includes a base plate 12 and a first side plate 13 and a second side plate 14 disposed on both sides of the base plate 12. The base plate 12, the first side plate 13, and the second side plate 14 form an oil-containing cavity 11. An opening is formed between the top of the first side plate 13 and the top of the second side plate 14. A cover 211 is placed on the first side plate 13. An input part 22 and an output part 23 are disposed on the outer surface of the first side plate 13. Specifically, the structural design of the spoiler body 10, consisting of the base plate 12, the first side plate 13, and the second side plate 14, not only realizes the storage and circulation of lubricating oil in terms of function, but also brings multiple advantages in terms of space utilization and system integration. The oil-containing cavity 11 formed by the base plate 12, the first side plate 13, and the second side plate 14 provides a storage space of moderate capacity for lubricating oil, ensuring that there is a sufficient amount of lubricating oil to maintain good lubrication and cooling of the gears when the lubricating oil circulates inside the gearbox, avoiding excessive wear and equipment failure caused by insufficient lubricating oil. The input section 22 and the output section 23 are disposed on the outer surface of the first side plate 13. This arrangement simplifies the access and discharge of the heat exchange fluid, reduces complex piping, and lowers the complexity and cost of the system.

[0037] like Figures 1 to 6 As shown, the heat exchange structure 20 also includes multiple heat-conducting elements 212 passing through the cover 211. Each heat-conducting element 212 has a first section located within the heat exchange channel and a second section located within the oil cavity 11. The second section is spaced apart from the gear 1. Specifically, the second section does not interfere with the gear 1, and it increases the contact area with the lubricating oil, allowing heat from the lubricating fluid to be exchanged onto the second section and then transferred to the first section. Since the first section is in contact with the heat exchange fluid, heat is transferred from the first section to the heat exchange fluid, thus achieving heat exchange of the lubricating oil. It should be noted that "the second section located within the oil cavity 11" means that the second section is directly located within the oil cavity 11 and directly in contact with the lubricating fluid, or that the second section is located within the range of the oil cavity 11.

[0038] Furthermore, in this embodiment, the heat-conducting component 212 is made of metal. Using metal as the core material for the heat-conducting component 212 offers several advantages: Metals, especially copper, aluminum, and silver, possess excellent thermal conductivity. This means that when the heat exchange fluid flows through the heat exchange channel, the metal heat-conducting component 212 can quickly absorb and conduct heat, accelerating the heat exchange process and effectively reducing the temperature of gear 1 and the surrounding lubricating oil, thereby improving the overall thermal management efficiency of the gearbox. The strength and stability of metals are superior to many other materials, enabling them to withstand the high-pressure and high-speed flowing lubricating oil environment inside the spoiler assembly. This durability ensures that the heat-conducting component 212 is not easily deformed or damaged during long-term use, maintaining its structural integrity and thermal conductivity even under extreme conditions, thus enhancing the reliability of the spoiler assembly. Metals have good machinability, allowing for the manufacture of complex shapes and structures through casting, forging, and machining to meet the design requirements of different heat exchange channels. Simultaneously, the metal heat-conducting component 212 is relatively easy to replace and maintain after damage or wear, reducing maintenance difficulty and time costs. The spoiler body 10 and the cover 211 are made of plastic.

[0039] like Figures 1 to 5 as well as Figure 7 As shown, the spoiler assembly also includes a switching structure 30. The base plate 12 has a first through hole 121. The switching structure 30 is disposed on the base plate 12 and located at the first through hole 121. The switching structure 30 is used to open or close the first through hole 121 so that the lubricating oil outside the spoiler assembly flows into the oil receiving cavity 11 or blocks the lubricating oil outside the spoiler assembly from flowing into the oil receiving cavity 11. Specifically, when the overall temperature of the gearbox is low (e.g., at the start of operation), the lubricating oil is at a low temperature and has a high viscosity. The user can control the on / off structure 30 to block the lubricating oil outside the spoiler assembly from flowing into the oil chamber 11, so that the amount of lubricating oil in the oil chamber 11 is not excessive, thereby hindering the operation of gear 1. When the overall temperature of the gearbox is high (e.g., during continuous operation), the lubricating oil will be continuously heated by components such as gear 1, resulting in a high temperature of the lubricating oil. The user can control the on / off structure 30 to allow the lubricating oil outside the spoiler assembly to flow into the oil chamber 11, so that the lubricating oil can continuously contact the heat exchange structure 20, thereby achieving the effect of controlling the overall temperature of the lubricating oil and ensuring the lubrication performance of the lubricating oil.

[0040] like Figures 1 to 5 as well as Figure 7As shown, the switching structure 30 includes a mounting shell 31, a blocking block 32, and a driving part 33. The mounting shell 31 is disposed on the outer surface of the base plate 12. The mounting shell 31 has a mounting cavity 311 communicating with the first through hole 121 and a second through hole 312 communicating with the mounting cavity 311. The blocking block 32 and the driving part 33 are both disposed within the mounting cavity 311. The blocking block 32 is movably disposed and has a connected state and a blocked state. The driving part 33 drives the blocking block 32 to switch between the connected state and the blocked state. When the blocking block 32 is in the blocked state, it blocks the first through hole 121 and the second through hole 312. When the blocking block 32 is in the connected state, it connects the first through hole 121 and the second through hole 312. Specifically, the driving part 33 can drive the blocking block 32 to move, thereby realizing the switching of different states of the blocking block 32, and thus realizing the connection or blockage between the first through hole 121 and the second through hole 312.

[0041] like Figures 1 to 5 as well as Figure 7 As shown, the mounting cavity 311 extends laterally and includes a first cavity 3111, a second cavity 3112, and a connecting port 3113 connecting the first cavity 3111 and the second cavity 3112. The first cavity 3111 communicates with the first through hole 121, and the second cavity 3112 communicates with the second through hole 312. The sealing block 32 is movably disposed within the first cavity 3111 or the second cavity 3112. When the sealing block 32 is in a blocking state, it blocks the connecting port 3113; when it is in a communicating state, it opens the connecting port 3113. Specifically, the sealing block 32 achieves communication or blockage between the first through hole 121 and the second through hole 312 by blocking or opening the connecting port 3113.

[0042] like Figures 1 to 5 as well as Figure 7As shown, the driving unit 33 includes a temperature-sensing deformation element 331 and a spring element 332. The sealing block 32 is disposed in the first cavity 3111. The temperature-sensing deformation element 331 is located in the second cavity 3112 and abuts against the first end of the sealing block 32. The spring element 332 is located in the first cavity 3111 and abuts against the second end of the sealing block 32. The temperature-sensing deformation element 331 has a first volume at a first preset temperature and a second volume at a second preset temperature. The first preset temperature is greater than the second preset temperature, and the first volume is greater than the second volume. When the temperature-sensing deformation element 331 switches from the second volume to the first volume, the temperature-sensing deformation element 331 drives the sealing block 32 to move toward the spring element 332, thereby causing the sealing block 32 to switch to the connected state. When the temperature-sensing deformation element 331 switches from the first volume to the second volume, the spring element 332 drives the sealing block 32 to move toward the temperature-sensing deformation element 331, thereby causing the sealing block 32 to switch to the blocking state. Specifically, the temperature-sensitive deformation element 331 can be made of paraffin wax. The temperature-sensitive deformation element 331 achieves volume change through thermal expansion and contraction. The volume change of the temperature-sensitive deformation element 331 and the elastic properties of the spring element 332 work together to achieve the movement of the sealing block 32.

[0043] This application also provides a gearbox device, which includes a housing, a gear 1, a spoiler assembly, and lubricating oil disposed within the housing. The input portion 22 and output portion 23 of the spoiler assembly pass through the housing. The spoiler assembly is the aforementioned spoiler assembly. The aforementioned spoiler assembly effectively solves the problem of excessively high lubricating oil temperature during gearbox operation in related technologies, and the gearbox device with the aforementioned spoiler assembly also has the above-mentioned advantages.

[0044] This application also provides a vehicle that includes a reduction gearbox assembly, wherein the reduction gearbox assembly is the aforementioned reduction gearbox assembly. The aforementioned reduction gearbox assembly can effectively solve the problem of excessively high lubricating oil temperature during reduction gearbox operation in related technologies, and vehicles equipped with the aforementioned reduction gearbox assembly also have the aforementioned advantages.

The temperature-sensitive deformation element (331) is located in the second cavity (3112) and abuts against the first end of the sealing block (32). The spring element (332) is located in the first cavity (3111) and abuts against the second end of the sealing block (32). The temperature-sensitive deformation element (331) has a first volume at a first preset temperature and a second volume at a second preset temperature. The first preset temperature is greater than the second preset temperature. At a preset temperature, the first volume is larger than the second volume. When the temperature-sensing deformation element (331) switches from the second volume to the first volume, the temperature-sensing deformation element (331) drives the sealing block (32) to move toward the spring element (332), thereby causing the sealing block (32) to switch to the connected state. When the temperature-sensing deformation element (331) switches from the first volume to the second volume, the spring element (332) drives the sealing block (32) to move toward the temperature-sensing deformation element (331), thereby causing the sealing block (32) to switch to the blocking state.
