[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following is for reference. Figures 1-6 This invention describes a heat preservation device 100 for a drive axle and a vehicle according to an embodiment of the present invention.

[0032] The heat preservation device 100 for the drive axle according to an embodiment of the present utility model includes: a first heat preservation shell 10 and a second heat preservation shell 20, the first heat preservation shell 10 and the second heat preservation shell 20 being opposite to and connected, the first heat preservation shell 10 and the second heat preservation shell 20 jointly defining an installation space 30, the installation space 30 being used to install the drive axle, and at least one of the first heat preservation shell 10 and the second heat preservation shell 20 being used to be fixedly connected to the drive axle.

[0033] The heat preservation device 100 includes a first heat preservation shell 10 and a second heat preservation shell 20. The first heat preservation shell 10 and the second heat preservation shell 20 are opposite to and connected. For example, the first heat preservation shell 10 and the second heat preservation shell 20 can be riveted together or snapped together. However, this utility model is not limited to this. The first heat preservation shell 10 and the second heat preservation shell 20 can also be connected in other ways, as long as the first heat preservation shell 10 and the second heat preservation shell 20 are opposite to and connected.

[0034] The first insulation shell 10 and the second insulation shell 20 are opposite to and connected, so that the first insulation shell 10 and the second insulation shell 20 together define an installation space 30, which is used to install the drive axle. Specifically, the first insulation shell 10 and the second insulation shell 20 are opposite to and connected, and can together form an installation space 30. The installation space 30 can be a closed space or a space with an open end. The drive axle is installed in the installation space 30. The first insulation shell 10 and the second insulation shell 20 can effectively isolate low temperature air, moisture, etc. in the external environment. Under extreme low temperature conditions, the insulation device 100 can reduce the direct impact of external cold air on the drive axle, thereby protecting the lubricating oil, seals and other sensitive components inside the drive axle from damage.

[0035] Furthermore, the drive axle generates a certain amount of heat during operation. In low-temperature environments, if the drive axle directly dissipates heat to the external environment, its internal temperature may become too low, thus affecting its normal operation and performance. The heat preservation device 100 effectively slows down the rate at which the drive axle dissipates heat to the external environment, helping to maintain a stable internal operating temperature. This prevents the lubricating oil in the drive axle from increasing in viscosity due to low temperatures, thereby reducing the transmission resistance of the drive axle, improving its transmission efficiency, and also helping to extend its service life.

[0036] Furthermore, at least one of the first insulation shell 10 and the second insulation shell 20 is used for fixed connection with the drive axle. For example, the first insulation shell 10 is used for fixed connection with the drive axle, or the second insulation shell 20 is used for fixed connection with the drive axle, or both the first insulation shell 10 and the second insulation shell 20 are fixedly connected with the drive axle. This application uses the example of both the first insulation shell 10 and the second insulation shell 20 being fixedly connected with the drive axle for illustration. The drive axle can be fixedly connected to the first insulation shell 10 and the second insulation shell 20 by bolts, or the drive axle can be fixedly connected to the first insulation shell 10 and the second insulation shell 20 by snap fasteners. However, this utility model is not limited to this. The drive axle can also be fixedly connected to the first insulation shell 10 and the second insulation shell 20 by other means, as long as both the first insulation shell 10 and the second insulation shell 20 are fixedly connected with the drive axle.

[0037] Both the first insulation shell 10 and the second insulation shell 20 are fixedly connected to the drive axle, ensuring a secure connection between the insulation device 100 and the drive axle. This guarantees the stability of the insulation device 100 on the drive axle, preventing displacement or detachment. It also helps reduce the impact of the external environment on the internal temperature of the insulation device 100, allowing it to better maintain internal temperature stability and thus ensuring the continuity and reliability of the insulation effect. Furthermore, the fixed connection of both the first insulation shell 10 and the second insulation shell 20 to the drive axle also enhances the overall structural strength, helping to resist external impacts and vibrations, thereby protecting the drive axle.

[0038] Therefore, by installing the drive axle within the installation space 30 of the insulation device 100 and fixing the insulation device 100 to the drive axle, the insulation device 100 can isolate the drive axle from the external environment. In low-temperature environments, the insulation device 100 can effectively slow down the rate at which the drive axle dissipates heat to the external environment, thus providing insulation for the drive axle and helping to maintain a stable internal working temperature. This, in turn, can improve the working efficiency of the drive axle and reduce the energy consumption of the entire vehicle. At the same time, the insulation device 100 can also protect the drive axle from pollution and corrosion from the external environment, thereby improving its overall reliability and durability.

[0039] According to some embodiments of this utility model, the first insulation shell 10 and the second insulation shell 20 can be detachably connected, making the connection between the first insulation shell 10 and the second insulation shell 20 simpler, and also making the first insulation shell 10 and the second insulation shell 20 more flexible in processing and manufacturing. The materials and dimensions can be adjusted according to actual needs, thereby reducing material costs. Furthermore, when one of the first insulation shell 10 and the second insulation shell 20 needs to be repaired or replaced, it is not necessary to disassemble the entire insulation device 100, which can reduce the maintenance cost of the insulation device 100.

[0040] According to some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, a first mounting structure 11 can be formed on the edge of the first insulation shell 10 facing the second insulation shell 20, and a second mounting structure 21 can be formed on the edge of the second insulation shell 20 facing the first insulation shell 10. The first mounting structure 11 and the second mounting structure 21 are snapped together to fix the relative positions of the first insulation shell 10 and the second insulation shell 20.

[0041] The snap-fit ​​connection between the first mounting structure 11 and the second mounting structure 21 ensures a tight fit between the first insulation shell 10 and the second insulation shell 20, preventing gaps between them and thus improving the insulation effect of the insulation device 100. The snap-fit ​​connection, through physical locking, makes the connection between the first insulation shell 10 and the second insulation shell 20 more secure, helping the insulation device 100 resist impacts and vibrations from the external environment and maintain its integrity. Furthermore, the snap-fit ​​connection simplifies the connection between the first insulation shell 10 and the second insulation shell 20, reducing installation difficulty and improving installation efficiency.

[0042] As an example of this application, there can be multiple first mounting structures 11 and multiple second mounting structures 21. The multiple first mounting structures 11 and multiple second mounting structures 21 are configured in a one-to-one correspondence. One of the first mounting structures 11 and multiple second mounting structures 21 can be constructed as a snap-fit ​​flange, and the other can be constructed as a snap-fit ​​groove. Each first mounting structure 11 can form a first mounting hole 111, and each second mounting structure 21 can form a second mounting hole 211. The multiple first mounting holes 111 and multiple second mounting holes 211 are configured in a one-to-one correspondence. When connecting the first insulation shell 10 and the second insulation shell 20, the corresponding snap-fit ​​flanges are inserted into the corresponding snap-fit ​​grooves. After the corresponding snap-fit ​​flanges are inserted into the corresponding snap-fit ​​grooves, the first mounting hole 111 of the first mounting structure 11 and the second mounting hole 211 of the second mounting structure 21 correspond one-to-one. A button buckle structure can be inserted through the first mounting hole 111 and the second mounting hole 211 to form a firm mechanical lock, thereby effectively preventing relative displacement or separation between the first insulation shell 10 and the second insulation shell 20, ensuring the stability and reliability of the insulation device 100. The installation and disassembly of the button buckle structure are relatively simple, requiring no special tools or complicated operating steps, greatly reducing the assembly and maintenance complexity of the insulation device 100. By adjusting the position and number of the first mounting structure 11 and the second mounting structure 21, insulation devices 100 of different sizes and shapes can be accommodated.

[0043] According to some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, at least one of the first insulation shell 10 and the second insulation shell 20 is provided with a third mounting structure 40, which is used to connect to the drive axle.

[0044] In this embodiment, at least one of the first insulation shell 10 and the second insulation shell 20 is provided with a third mounting structure 40. For example, the first insulation shell 10 is provided with a third mounting structure 40, or the second insulation shell 20 is provided with a third mounting structure 40, or both the first insulation shell 10 and the second insulation shell 20 are provided with a third mounting structure 40. This application will use the example of both the first insulation shell 10 and the second insulation shell 20 being provided with a third mounting structure 40 for illustration.

[0045] The third mounting structure 40 is used to connect with the drive axle, and can fix both the first insulation shell 10 and the second insulation shell 20 to the drive axle. This ensures the stability of the insulation device 100 on the drive axle, preventing displacement or detachment, and helps reduce the impact of the external environment on the internal temperature of the insulation device 100. This allows the insulation device 100 to better maintain its internal temperature stability, thus ensuring the continuity and reliability of the insulation effect. Furthermore, the fixed connection of both the first insulation shell 10 and the second insulation shell 20 to the drive axle also enhances the overall structural strength to a certain extent, helping to resist external impacts and vibrations, thereby further protecting the drive axle.

[0046] As an example of this application, the third mounting structure 40 can be a snap-fit ​​structure. The third mounting structure 40 is used to connect the drive axle and the insulation device 100, making the connection and disassembly between the insulation device 100 and the drive axle quick and efficient. The snap-fit ​​structure achieves a secure connection through its internal springs or snap-fit ​​structure, capable of withstanding certain external forces and vibrations, ensuring the stability of the insulation device 100 on the drive axle. The snap-fit ​​structure can be customized according to different sizes and shapes, allowing the third mounting structure 40 to adapt to different models and specifications of drive axles and insulation devices 100, improving versatility and flexibility. Furthermore, the snap-fit ​​structure can be repeatedly engaged and disengaged without damaging its structure or performance. Therefore, in high-temperature environments where the lubricating oil temperature inside the drive axle exceeds the allowable range, the insulation device 100 can be quickly removed from the drive axle. In low-temperature environments, the insulation device 100 can also be quickly installed on the drive axle, helping to reduce heat loss from the drive axle and improve its operating efficiency. The quick installation and disassembly of the snap-fit ​​structure makes the maintenance of the insulation device 100 more efficient, helps to reduce maintenance costs, and improves the reliability and availability of the insulation device 100.

[0047] According to some embodiments of the present invention, such as Figure 1As shown, the first insulation shell 10 and the second insulation shell 20 can jointly define a first clearance hole 41 for avoiding structural components. The clearance hole can be used to avoid components such as the drive axle housing and gearbox accessories. It can be reasonably designed according to the actual situation, so as to avoid interference between the insulation device 100 and the drive axle and other components, which helps to maintain the normal operation of the equipment and avoid failures or damage caused by interference.

[0048] According to some embodiments of this utility model, there can be multiple first clearance holes 41, such as two, three, four, etc. However, this utility model is not limited to this, and there can be other numbers of first clearance holes 41, as long as there are multiple first clearance holes 41. The number of first clearance holes 41 can be reasonably set according to the actual situation, as long as it can avoid interference between the heat preservation device 100 and the drive bridge and other components. The setting of multiple first clearance holes 41 can further avoid interference between the heat preservation device 100 and the drive bridge and other components, which helps to maintain the normal operation of the equipment and further avoids failures or damage caused by interference.

[0049] According to some embodiments of the present invention, such as Figure 1 As shown, the second insulation shell 20 may have a second clearance hole 22 for avoiding structural components. Specifically, the second clearance hole 22 can be used to avoid the oil plug, preventing interference between the insulation device 100 and the oil plug, which helps to maintain the normal operation of the equipment, avoids failures or damage caused by interference, and also improves the convenience of drive axle maintenance. For example, when it is necessary to change the lubricating oil or check the oil level, the staff can easily access the oil plug without disassembling the insulation device 100.

[0050] According to some embodiments of the present invention, such as Figure 2 and Figure 6As shown, both the first insulation shell 10 and the second insulation shell 20 may include an outer shell 31 and an insulation layer 32. The outer shell 31 may be made of EPDM (Ethylene Propylene Diene Monomer) material. EPDM has excellent weather resistance, ozone resistance, chemical corrosion resistance, and good electrical insulation properties, enabling the outer shell 31 to protect and support the insulation layer 32, while also possessing a certain strength and durability to withstand various pressures and impacts from the external environment. The insulation layer 32 may be made of sound-absorbing cotton material. Sound-absorbing cotton is a porous material with good sound absorption and heat insulation properties, effectively absorbing and isolating noise while reducing heat transfer and improving the insulation effect of the insulation device 100. The insulation layer 32 is fixed to the inner surface of the outer shell 31. The insulation layer 32 and the outer shell 31 can be bonded together to ensure a tight bond between the insulation layer 32 and the outer shell 31, preventing heat loss through gaps. At the same time, the bonding connection can also improve the overall structural strength of the insulation device 100, making it more durable, thereby improving the insulation effect and service life of the insulation device 100.

[0051] According to some embodiments of the present invention, the shape of the insulation layer 32 and the shape of the outer shell 31 can be adapted. The adapted shape helps to achieve a better sealing effect, can minimize the gap between the insulation layer 32 and the outer shell 31, can significantly improve the insulation effect, reduce energy loss, and the adapted shape can also ensure that the connection between the insulation layer 32 and the outer shell 31 is more firm, thereby improving the overall strength of the entire insulation device 100.

[0052] According to some embodiments of the present invention, such as Figure 1 As shown, the insulation device 100 can also have multiple drainage holes 42. For example, the insulation device 100 can have two, three, four, or other numbers of drainage holes 42. However, this utility model is not limited to this, and the insulation device 100 can also have other numbers of drainage holes 42, as long as the insulation device 100 has multiple drainage holes 42. During the operation of the drive axle or the use of the insulation device 100, a certain amount of moisture or liquid may be generated inside the insulation device 100. By setting multiple drainage holes 42, the moisture or liquid can be drained in time, thereby maintaining a dry environment inside the insulation device 100, protecting the drive axle from moisture damage, and helping to extend the service life of the drive axle.

[0053] The vehicle according to an embodiment of the present invention includes: a drive axle; and a thermal insulation device 100, wherein the thermal insulation device 100 is the same as the thermal insulation device 100 described in the above embodiment. At least a portion of the drive axle is mounted within the installation space 30, which allows the thermal insulation device 100 to isolate at least a portion of the drive axle from the external environment. In low-temperature environments, the thermal insulation device 100 can effectively slow down the rate at which the drive axle dissipates heat to the external environment, thus providing thermal insulation for the drive axle and helping to maintain a stable internal working temperature. This, in turn, improves the working efficiency of the drive axle and reduces the energy consumption of the entire vehicle. At the same time, the thermal insulation device 100 can also protect the drive axle from pollution and corrosion from the external environment, thereby improving its overall reliability and durability.
