Description

Technical Field

[0001] This utility model relates to the field of automotive thermal management system technology, specifically to a driving device for a six-way water valve in an automotive thermal management system. Background Technology

[0002] An automotive thermal management system is a comprehensive system designed to optimize and control heat transfer within a vehicle. By adjusting cooling intensity, it ensures that the cooled components operate within their optimal temperature range, thereby improving the vehicle's environmental performance and fuel efficiency, while also enhancing safety and driving comfort.

[0003] The multi-way water valves used in the water-side circulation loop of existing automotive thermal management systems typically have a spherical or cylindrical valve core with a fan-shaped cavity inside. By rotating the valve core at different angles, the cavity can be connected to different pipe ports. However, due to structural limitations, this solution is generally made into a four-way valve, which can use a motor to drive the rotation of the valve core to connect the cavity to different pipe ports. This cannot meet the requirements of six-channel control. Utility Model Content

[0004] The purpose of this utility model is to provide a driving device for a six-way water valve in a vehicle thermal management system, which solves the problem that in the prior art, when the valve core is made into a spherical or cylindrical shape, it can only be made into a four-way valve due to structural limitations.

[0005] This utility model provides the following technical solution: a driving device for a six-way water valve in a vehicle thermal management system, comprising a valve body, two cylindrical valve cores fixedly installed on the inner wall of the valve body, a left grooved wheel assembly located on the top of the left cylindrical valve core, two support members fixedly installed on the inner wall of the valve body, a left ratchet assembly rotatably connected to the top of the left support member, the left side of the left ratchet assembly meshing with the right side of the left grooved wheel assembly, a right ratchet assembly rotatably connected to the top of the right support member, a right grooved wheel assembly located on the top of the right cylindrical valve core, the left side of the right grooved wheel assembly meshing with the right side of the right ratchet assembly, a reduction gear set located at the bottom of the inner wall of the valve body, a motor assembly fixedly installed on the inner wall of the valve body, the output end of the motor assembly meshing with the input end of the reduction gear set, and the output end of the reduction gear set meshing with the left and right ratchet assemblies.

[0006] As a preferred embodiment of the above technical solution, the outer wall of the valve body is fixedly connected with a pipe opening, and the number of the pipe openings is set to six, of which four pipe openings are symmetrically distributed on the front and back of the valve body, and the other two pipe openings are symmetrically distributed on both sides of the valve body.

[0007] As a preferred embodiment of the above technical solution, the cylindrical valve core is evenly divided into four flow channels around its perimeter. Two adjacent flow channels are connected to one of the flow channels inside the valve body, and two flow channels that are far apart from each other are connected to one of the flow channels inside the valve body. The inner diameter of the flow channel is the same as the diameter of the pipe opening.

[0008] As a preferred embodiment of the above technical solution, the left groove wheel assembly and the right groove wheel assembly have the same specifications, the outer surface of the left groove wheel assembly is provided with an arc groove and a U-shaped groove, and the bottom of the left groove wheel assembly is provided with an internal tooth hole.

[0009] As a preferred embodiment of the above technical solution, the left ratchet assembly and the right ratchet assembly have the same specifications. An arc-shaped block is fixedly connected to the center of the top of the right ratchet assembly, a protruding block is fixedly connected to the top of the right ratchet assembly, and a transmission gear is fixedly connected to the bottom of the right ratchet assembly. The transmission gear meshes with the output end of the reduction gear set.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model, through the design of the motor assembly, can drive two cylindrical valve cores to perform intermittent motion via a reduction gear set, left groove wheel assembly, left ratchet assembly, right ratchet assembly, and right groove wheel assembly. By controlling the movement angle of the left and right cylindrical valve cores, the six ports can be connected and disconnected. This driving method is the same as that of a four-way valve, but it realizes the function of a six-way valve control, meets the user's needs, saves the installation space of the automotive thermal management system, and improves the driving efficiency.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1-3 As shown, this utility model provides a technical solution: a driving device for a six-way water valve in a vehicle thermal management system, including a valve body 9, with two cylindrical valve cores 8 fixedly installed on the inner wall of the valve body 9. A left grooved wheel assembly 1 is provided on the top of the left cylindrical valve core 8. Two support members 7 are fixedly installed on the inner wall of the valve body 9. A left ratchet assembly 2 is rotatably connected to the top of the left support member 7, with the left side of the left ratchet assembly 2 meshing with the right side of the left grooved wheel assembly 1. A right ratchet assembly 3 is rotatably connected to the top of the right support member 7, with a right grooved wheel assembly 4 provided on the top of the right cylindrical valve core 8. The left side of the right grooved wheel assembly 4... Engaging with the right side of the right ratchet assembly 3, a reduction gear set 5 is provided at the bottom of the inner wall of the valve body 9. A motor assembly 6 is fixedly installed on the inner wall of the valve body 9. The output end of the motor assembly 6 engages with the input end of the reduction gear set 5. The output end of the reduction gear set 5 engages with the left ratchet assembly 2 and the right ratchet assembly 3. Controlling the operation of the motor assembly 6 can drive the reduction gear set 5 to run. The reduction gear set 5 will drive the left ratchet assembly 2 and the right ratchet assembly 3 to rotate synchronously. Then, through the transmission of the left groove wheel assembly 1 and the right groove wheel assembly 4, the two cylindrical valve cores 8 are driven to perform intermittent motion. By controlling the motion angle of the left and right cylindrical valve cores 8, the six ports 91 are connected and disconnected, realizing the function of six-way valve control.

[0018] As one implementation method in this embodiment, such as Figures 1-3 As shown, six ports 91 are fixedly connected to the outer wall of the valve body 9. Four ports 91 are symmetrically distributed on the front and back of the valve body 9, and the other two ports 91 are symmetrically distributed on both sides of the valve body 9. The distribution of the ports 91 facilitates the connection of the water circulation pipeline. The cylindrical valve core 8 has four flow channels evenly distributed around its perimeter. Two adjacent flow channels are connected to one of the flow channels inside the valve body 9, and two flow channels that are far apart from each other are connected to one of the flow channels inside the valve body 9. The inner diameter of the flow channel is the same as the diameter of the port 91. Through the above design, low flow resistance characteristics under high flow rate can be guaranteed.

[0019] As one implementation method in this embodiment, such as Figures 1-3As shown, the left groove wheel assembly 1 and the right groove wheel assembly 4 have the same specifications. The outer surface of the left groove wheel assembly 1 has an arc-shaped groove 11 and a U-shaped groove 12. The bottom of the left groove wheel assembly 1 has an internal tooth hole 13. The left ratchet assembly 2 and the right ratchet assembly 3 have the same specifications. An arc-shaped block 31 is fixedly connected to the center of the top of the right ratchet assembly 3. A protrusion 32 is fixedly connected to the top of the right ratchet assembly 3. A transmission gear 33 is fixedly connected to the bottom of the right ratchet assembly 3. The transmission gear 33 meshes with the output end of the reduction gear set 5. When the left groove wheel assembly 1, left ratchet assembly 2, right ratchet assembly 3, and right groove wheel assembly 4 are installed, their initial position is 90°. The left ratchet assembly 2 and right ratchet assembly 3 are driven by the same reduction gear set 5 and rotate simultaneously. However, due to… Because the initial position is 90°, only the left ratchet assembly 2 or the right ratchet assembly 3 rotates at the same time. The upper parts of the left grooved wheel assembly 1 and the right grooved wheel assembly 4 respectively engage with the left ratchet assembly 2 and the right ratchet assembly 3. There are four grooves evenly arranged on the circumference of the left grooved wheel assembly 1 and the right grooved wheel assembly 4. The outer diameter of the protrusion 32 matches the width of the U-shaped groove 12, and the outer wall of the arc-shaped block 31 matches the shape of the arc-shaped groove 11, which facilitates the transmission. Through the design of the internal tooth hole 13 at the bottom of the left grooved wheel assembly 1 and the right grooved wheel assembly 4, it is easy for the left grooved wheel assembly 1 and the right grooved wheel assembly 4 to be connected to the cylindrical valve core 8. Through the design of the transmission gear 33, the bottom of the left ratchet assembly 2 and the right ratchet assembly 3 are connected to the reduction gear set 5.

[0020] Working principle: When in use, the control motor assembly 6 works, which drives the reduction gear set 5 to run. The reduction gear set 5 drives the left ratchet assembly 2 and the right ratchet assembly 3 to rotate synchronously. Then, through the transmission of the left groove wheel assembly 1 and the right groove wheel assembly 4, the two cylindrical valve cores 8 are driven to make intermittent movements. By controlling the movement angle of the left and right cylindrical valve cores 8, the six ports 91 are connected and disconnected to each other, realizing the function of six-way valve control.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
