Description

Technical Field

[0001] This utility model relates to the field of automotive thermal management technology, and in particular to a device for a thermal management system for new energy vehicles. Background Technology

[0002] New energy vehicle batteries refer to the battery systems used to power new energy vehicles. Currently, the main types include lithium-ion batteries, nickel-metal hydride batteries, and solid-state batteries. The thermal management system of new energy vehicles plays a crucial protective role for the battery, extending battery life, preventing thermal runaway, increasing energy density, adapting to different operating conditions, and improving overall efficiency. The battery is generally housed within the protective cover of the thermal management system. When a new energy vehicle malfunctions or requires maintenance and inspection, the protective cover of the thermal management system typically needs to be disassembled for observation and testing. To ensure a secure seal, existing thermal management system protective covers generally use numerous screws and nuts for fixation, resulting in slow disassembly or reassembly of the thermal management protective cover. Utility Model Content

[0003] To improve the aforementioned thermal management system's protective cover and ensure its sealing performance, it is generally fixed with a large number of screws and nuts. This leads to slow efficiency when disassembling or assembling the thermal management protective cover of new energy vehicles. This utility model provides a device with a thermal management system for new energy vehicles.

[0004] This utility model provides a device with a thermal management system for new energy vehicles, adopting the following technical solution:

[0005] A thermal management system device for new energy vehicles includes a lower support frame, an upper protective frame slidably mounted on the top of the lower support frame, and a vehicle battery housed inside the lower support frame.

[0006] A connecting frame is fixedly sleeved on the upper side of the upper protective frame, and connecting strips are fixedly provided on both sides of the bottom of the connecting frame. An installation groove is provided on the top of the lower support frame, and the interior of the installation groove slides in cooperation with the connecting strip.

[0007] T-shaped grooves are provided on the front and rear sides of the left and right sides of the lower support frame. A locking mechanism for connecting the lower support frame and the upper protective frame is slidably arranged inside the T-shaped groove. A liquid cooling pipe is fixedly installed on the side of the electric vehicle battery. One end of the liquid cooling pipe passes through the left side of the lower support frame and the upper protective frame and is fixedly connected to the motor controller.

[0008] The above technical solution facilitates the quick assembly and fixation of the lower support frame and the upper protective frame, and enables the rapid disassembly of new energy thermal management devices that have been sealed for a long time, allowing for the inspection and maintenance of the internal batteries.

[0009] Optionally, in the above-mentioned device for a new energy vehicle thermal management system, the bottom left and right sides of the connecting strip are beveled, and slots are provided on both the left and right sides of the connecting strip, and slots are provided in the middle of both the left and right sides of the connecting strip.

[0010] The above technical solution facilitates the movement of the insert block into the slot, thereby increasing the connection strength between the connecting strip and the lower support frame and the upper protective frame.

[0011] Optionally, in the above-mentioned device for a thermal management system for new energy vehicles, the engaging mechanism includes four T-shaped bars, which are slidably disposed inside the horizontal groove of the T-shaped groove. A limiting block is fixedly disposed on the side of the horizontal bar of the T-shaped bar, and the side of the limiting block slides into the interior of the vertical groove of the T-shaped groove. A first compression spring is fixedly disposed on the side of the limiting block, and one end of the first compression spring is fixedly connected to the interior of the vertical groove of the T-shaped groove.

[0012] The above technical solution facilitates the movement of the T-shaped strip within the transverse groove of the T-shaped groove by setting the limiting block and the T-shaped groove, while preventing the T-shaped strip from moving out of the T-shaped groove.

[0013] Optionally, in the above-mentioned device for a thermal management system for new energy vehicles, the side of the T-shaped horizontal bar is beveled, and the side of the T-shaped horizontal bar abuts against the lower side of the connecting bar. The inside of the slot slides with the side of the T-shaped horizontal bar, and an insert is fixedly provided on the side of the T-shaped vertical bar. The side of the insert slides with the inside of the slot.

[0014] A connecting plate is fixedly installed at the top of each of the two T-shaped bars that form a group.

[0015] With the above technical solution, the frictional force generated when the side of the T-shaped strip, which is easy to be angled, contacts the lower side of the connecting strip is smaller.

[0016] Optionally, in the above-mentioned device for a thermal management system for new energy vehicles, a retaining strip is fixedly provided on both the left and right sides of the lower support frame. The retaining strip, the bottom of the connecting plate, and the top of the retaining strip are all provided with annular grooves. The side of the annular groove contacts the side of the liquid cooling pipe. The vertical cross-section of the retaining strip and the connecting plate are both L-shaped, and the side of the connecting plate contacts the side of the retaining strip.

[0017] The above technical solution facilitates the protection of the liquid cooling pipe by means of the clip and the annular groove on the upper side of the connecting plate.

[0018] Optionally, in the above-mentioned device for a new energy vehicle thermal management system, a power-assisted grip is fixedly installed on the top of the connecting plate, and two fixing bolts are rotatably installed on the side of the connecting plate, with one end of each fixing bolt extending into the interior of the upper protective frame.

[0019] The above technical solution facilitates the use of a power grip to help workers move the connecting plate, while the fixing bolts make it easy to fix the lower support frame and the upper protective frame after they are engaged.

[0020] Optionally, in the above-mentioned device for a thermal management system for new energy vehicles, a square groove is provided inside the mounting slot, a second compression spring is fixedly provided at the bottom of the inner wall of the square groove, a square block is fixedly provided on the side of the connecting strip, and the side of the square block abuts against the top of the second compression spring.

[0021] With the above technical solution, after the lower support frame and the upper protective frame are closed, the square block can squeeze the second compression spring. When it is necessary to open the lower support frame and the upper protective frame, the rebound force of the second compression spring can drive the square block to move upward, thereby quickly separating the lower support frame and the upper protective frame.

[0022] In summary, this utility model has at least one of the following beneficial effects: when the upper protective frame and the lower support frame are fixed, the connecting strip moves into the mounting groove, and the connecting strip moves down to squeeze the T-shaped strip, causing the two T-shaped strips as a group to drive the limiting block and the insert block to open to both sides and compress the first compression spring. When the upper protective frame moves to contact the lower support frame, the first compression spring causes the horizontal bar of the T-shaped strip to move into the slot, and at the same time the insert block moves into the slot, so that the lower support frame and the upper protective frame can be quickly assembled and fixed.

[0023] By using the assist grip to move the two T-shaped bars to the sides, the horizontal bar of the T-shaped bar moves out of the slot, and the insert moves out of the slot, releasing the fixation between the lower support frame and the upper protective frame. At this time, the upper protective frame and the square block of the connecting frame move upward through the second compression spring, which can separate the lower support frame from the upper protective frame. This makes it easy to quickly disassemble the new energy thermal management device that has been sealed for a long time, and to inspect and maintain the battery inside. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0031] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides an embodiment of a new energy vehicle thermal management system device, comprising a lower support frame 1, an upper protective frame 2 slidably disposed on the top of the lower support frame 1, and an electric vehicle battery 3 placed inside the lower support frame 1.

[0032] A connecting frame 4 is fixedly sleeved on the upper side of the upper protective frame 2. Connecting strips 5 are fixedly installed on both sides of the bottom of the connecting frame 4. An installation groove 6 is opened on the top of the lower support frame 1. The interior of the installation groove 6 is slidably engaged with the connecting strip 5.

[0033] T-shaped grooves 7 are provided on the front and rear sides of the left and right sides of the lower support frame 1. A locking mechanism 8 for connecting the lower support frame 1 and the upper protective frame 2 is slidably provided inside the T-shaped grooves 7. A liquid cooling pipe 9 is fixedly provided on the side of the electric vehicle battery 3. One end of the liquid cooling pipe 9 passes through the left side of the lower support frame 1 and the upper protective frame 2 and is fixedly connected to the motor controller 10.

[0034] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The bottom left and right sides of the connecting strip 5 are beveled, and the left and right sides of the connecting strip 5 are provided with slots 501. The middle of the left and right sides of the connecting strip 5 is provided with slots 502. After the insert block 803 is moved into the slot 502, the connection between the connecting strip 5 and the lower support frame 1 and the upper protective frame 2 can be strengthened.

[0035] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The engaging mechanism 8 includes four T-shaped bars 801, which are slidably disposed inside the horizontal groove of the T-shaped groove 7. A limiting block 802 is fixedly disposed on the side of the horizontal bar of the T-shaped bar 801. The side of the limiting block 802 is slidably engaged with the inside of the vertical groove of the T-shaped groove 7. A first compression spring 805 is fixedly disposed on the side of the limiting block 802. One end of the first compression spring 805 is fixedly connected to the inside of the vertical groove of the T-shaped groove 7. The setting of the limiting block 802 and the T-shaped groove 7 enables the T-shaped bar 801 to move inside the horizontal groove of the T-shaped groove 7, while preventing the T-shaped bar 801 from moving out of the inside of the T-shaped groove 7.

[0036] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The side of the horizontal bar of the T-shaped bar 801 is beveled, and the side of the horizontal bar of the T-shaped bar 801 abuts against the lower side of the connecting bar 5. The inside of the slot 501 slides with the side of the horizontal bar of the T-shaped bar 801. The side of the vertical bar of the T-shaped bar 801 is fixedly provided with an insert 803, and the side of the insert 803 slides with the inside of the slot 502.

[0037] The top of each of the two T-shaped bars 801 is fixedly provided with a connecting plate 804. The friction generated when the side of the horizontal bar of the T-shaped bar 801 with the beveled treatment contacts the lower side of the connecting bar 5 is small.

[0038] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The lower support frame 1 is fixedly provided with a retaining strip 101 on both the left and right sides. The bottom of the retaining strip 101 and the top of the retaining strip 101 are provided with annular grooves 102. The side of the annular groove 102 contacts the side of the liquid cooling pipe 9. The vertical cross-section of the retaining strip 101 and the connecting plate 804 are both L-shaped, and the side of the connecting plate 804 contacts the side of the retaining strip 101. The retaining strip 101 and the annular groove 102 on the upper side of the connecting plate 804 facilitate the protection of the liquid cooling pipe 9.

[0039] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The top of the connecting plate 804 is fixedly provided with an assistive grip 806, and the side of the connecting plate 804 is provided with two fixing bolts 807. One end of the fixing bolts 807 extends into the interior of the upper protective frame 2. The assistive grip 806 facilitates the movement of the connecting plate 804 by the staff, and the fixing bolts 807 facilitate the fixing of the lower support frame 1 and the upper protective frame 2 after they are engaged.

[0040] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The mounting groove 6 has a square groove 601 inside. A second compression spring 602 is fixedly installed at the bottom of the inner wall of the square groove 601. A square block 603 is fixedly installed on the side of the connecting strip 5. The side of the square block 603 abuts against the top of the second compression spring 602. When the lower support frame 1 and the upper protective frame 2 are closed, the square block 603 can squeeze the second compression spring 602. When it is necessary to open the lower support frame 1 and the upper protective frame 2, the rebound force of the second compression spring 602 can drive the square block 603 to move upward, thereby quickly separating the lower support frame 1 and the upper protective frame 2.

[0041] Working principle: When using this device with a new energy vehicle thermal management system, firstly, the upper protective frame 2 is fixed on the lower support frame 1. At the same time, the two connecting strips 5 move into the interior of the mounting groove 6. When the connecting strips 5 move down, they squeeze the T-shaped strips 801, causing the two T-shaped strips 801 as a group to drive the limiting block 802 and the insert block 803 to open to both sides respectively, and compress the first compression spring 805. When the upper protective frame 2 moves to contact the lower support frame 1, the rebound force of the first compression spring 805 causes the horizontal bar of the T-shaped strip 801 to move into the slot 501. At the same time, the insert block 803 moves into the slot 502, so that the lower support frame 1 and the upper protective frame 2 can be quickly assembled and fixed.

[0042] By gripping the two assist handles 806 and applying pressure to move them to the sides, the two T-shaped bars 801 move to the left and right sides respectively, causing the horizontal bars of the T-shaped bars 801 to move out of the slots 501. At the same time, the insert block 803 moves out of the slot 502, releasing the fixation between the lower support frame 1 and the upper protective frame 2. At this time, the upper protective frame 2 and the square block 603 of the connecting frame 4 move upward as a whole by the force generated by the rebound of the second compression spring 602, which can quickly separate the lower support frame 1 and the upper protective frame 2. This makes it convenient to quickly disassemble the new energy thermal management device that has been sealed for a long time and to inspect and maintain the battery inside.

[0043] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
