Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a water valve drive device. Background Technology

[0002] As an accessory to the water valve, the water valve motor is an essential component of modern automobiles. Based on signals from the vehicle control system, it can precisely control the opening degree of the water valve, thereby achieving precise regulation of the coolant flow.

[0003] The main structure of a water valve motor includes a housing, a motor, and a gear transmission system. Both the motor and the gear transmission system are mounted in the housing. The car precisely controls the rotation angle and speed of the motor, which in turn drives the water valve core to move or rotate, thereby achieving precise regulation of the coolant flow. For example, when the engine is running under high load and generating a lot of heat, the water valve motor receives a signal and will increase the opening of the water valve, allowing more coolant to flow through the engine, enhancing heat dissipation, and thus meeting the engine's heat dissipation needs under different operating conditions.

[0004] The power of existing water valve motors is mainly transmitted to the gear transmission system through gears. In order to ensure that the gears on the motor can mesh with the gears in the gear transmission system, the motor needs to be placed vertically in the housing, which creates a lot of unused space on the lower side of the gear transmission system. This results in the water valve motor having low compactness and large size. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a water valve drive device to solve the technical problems of low compactness and large size of water valve motors in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a water valve driving device, including:

[0008] case;

[0009] A driving component, mounted on the housing, has a rotary driving end;

[0010] The output component is rotatably connected to the housing and is used to connect a water valve;

[0011] The worm gear is fixed to the rotary drive end, and

[0012] A gear transmission module is installed in the housing and connects the worm gear and the output component, and is used to drive the output component to rotate through the rotation of the worm gear.

[0013] In some embodiments, the drive unit includes a brushless motor, the shaft of which forms the rotary drive end, and the worm gear is sleeved on the shaft.

[0014] In some embodiments, the surface of the machine shaft has a plurality of circumferentially spaced limiting strips, which are fitted into the inner side of the worm gear.

[0015] In some embodiments, the housing is provided with a support groove, and the end of the machine shaft is mounted in the support groove.

[0016] In some embodiments, the housing is further provided with a mounting groove, and the drive member is mounted in the mounting groove.

[0017] In some embodiments, the housing further includes limiting posts located on both sides of the mounting groove to radially limit the drive member.

[0018] In some embodiments, the housing further includes a positioning plate located on one end side of the mounting groove, and the end of the drive member is fixed to the positioning plate.

[0019] In some embodiments, the gear transmission module includes several stages of transmission gears meshing in sequence. Each stage of the transmission gear includes a large gear and a small gear. The large gear of the first stage of the transmission gear meshes with the worm gear, and the small gear of the last stage of the transmission gear meshes with the output component. Each stage of the transmission gear meshes with the large gear of the adjacent transmission gear through the small gear.

[0020] In some embodiments, the housing further has a plurality of rotating shafts, and each of the transmission gears is rotatably connected to each of the rotating shafts.

[0021] In some embodiments, the housing includes a bottom shell and a top cover, the drive member is mounted on the bottom shell, and the top cover covers the bottom shell and fits against the drive member.

[0022] Compared with the prior art, the water valve driving device provided by this utility model is configured with a housing, a driving component, an output component, a worm gear, and a gear transmission module. The driving component has a rotary driving end, and the worm gear is fixed to the rotary driving end, so it can rotate through the driving component. The output component is rotatably connected to the housing. The gear transmission module connects the worm gear and the output component. When the worm gear rotates, it can drive the output component to rotate through the transmission of the gear transmission module. Through the rotation of the output component, the power can be transmitted to the water valve to realize the control of the opening and closing of the water valve. Since the driving component can output power through the worm gear, and the axial direction of the worm gear is perpendicular to the axial direction of each gear of the gear transmission module, the driving component can be laid horizontally in the housing, thereby reducing the height of the housing, reducing the amount of idle space inside the housing, making the internal structure of the housing more compact, and thus reducing the size of the water valve driving device.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] To address the technical problems of low compactness and large size of existing water valve motors, this utility model provides a water valve drive device that enables the drive components of the drive device to be laid horizontally.

[0039] It should be noted that the water valve driving device described in this utility model is used for, but not limited to, driving water valves. For ease of explanation, this utility model only uses the application of the water valve driving device to drive water valves as an example. The driving principle of the water valve driving device applied to other equipment is essentially the same as that applied to water valves, and will not be described in detail here.

[0040] The water valve driving device of this utility model embodiment, such as Figure 1-5 As shown, it includes a housing 10, a drive component 20, an output component 30, a worm gear 40, and a gear transmission module 50. The drive component 20 is mounted on the housing 10 and has a rotary drive end. The output component 30 is rotatably connected to the housing 10 and is used to connect a water valve. The worm gear 40 is fixed to the rotary drive end. The gear transmission module 50 is mounted on the housing 10 and connects the worm gear 40 and the output component 30, and is used to drive the output component 30 to rotate through the rotation of the worm gear 40.

[0041] Specifically, the water valve drive device comprises a housing 10, a drive component 20, an output component 30, a worm gear 40, and a gear transmission module 50. The drive component 20 has a rotary drive end, and the worm gear 40 is fixed to the rotary drive end, thus allowing it to rotate. The output component 30 is rotatably connected to the housing 10. The gear transmission module 50 connects the worm gear 40 and the output component 30. When the worm gear 40 rotates, it drives the output component 30 to rotate through the transmission of the gear transmission module 50. The rotation of the output component 30 transmits power to the water valve, thereby controlling the opening and closing of the water valve. Since the drive component 20 can output power through the worm gear 40, and the axial direction of the worm gear 40 is perpendicular to the axial direction of each gear in the gear transmission module 50, the drive component 20 can be laid horizontally on the housing 10, thereby reducing the height of the housing 10, reducing the idle space inside the housing 10, making the internal structure of the housing 10 more compact, and thus reducing the size of the water valve drive device.

[0042] In one embodiment, such as Figure 1-3 As shown, the housing 10 includes a bottom shell 11 and a top cover 12. The driving member 20 is mounted on the bottom shell 11, and the top cover 12 covers the bottom shell 11 and fits against the driving member 20. Specifically, the top cover 12 covers the bottom shell 11, forming a mounting cavity structure with the bottom shell 11. By fitting against the driving member 20, the top cover 12 can press against the driving member 20, restricting its movement and thus stabilizing it.

[0043] In one embodiment, such as Figure 4-5As shown, the housing 10 is also provided with a mounting groove 13, in which the drive component 20 is mounted. Specifically, the mounting groove 13 can, on the one hand, accommodate the drive component 20 to achieve stability of the drive component 20, and on the other hand, by accommodating the lower side of the drive component 20, reduce the height of the mounting cavity, making the internal structure of the housing 10 more compact and further reducing the volume of the drive device.

[0044] In one embodiment, such as Figure 5 As shown, the housing 10 also has limiting posts 14, which are located on both sides of the mounting groove 13 to radially limit the drive member 20. Specifically, the limiting posts can provide limiting for the drive member 20 on both sides to ensure the stability of the drive member 20.

[0045] In one embodiment, such as Figure 3-4 As shown, the housing 10 also has a positioning plate 15, which is located on one side of the end of the mounting groove 13, and the end of the drive member 20 is fixed to the positioning plate 15. Specifically, by fixing the drive member 20 to the positioning plate 15, it is fixed inside the housing 10 and prevents the drive member 20 from rotating, thereby ensuring the control accuracy of the drive device.

[0046] In this embodiment, the drive component 20 is fixed to the positioning plate 15 by screws.

[0047] Understandably, the drive unit 20 can be any drive device that can drive the worm gear 40 to rotate, such as a DC motor, AC motor, pneumatic equipment, or hydraulic equipment.

[0048] In one embodiment, such as Figure 3-5 As shown, the drive unit 20 includes a brushless motor 21, with the shaft 211 of the brushless motor 21 forming a rotary drive end, and a worm gear 40 sleeved on the shaft 211. Specifically, the brushless motor 21 has more stable working performance and a smaller size, ensuring stable performance of the drive device while reducing the size of the drive device.

[0049] In one embodiment, the surface of the shaft 211 has a plurality of circumferentially spaced limiting strips 212212, which engage with the inner side of the worm 40. Specifically, the worm 40 achieves a stable connection with the shaft 211 by engaging with the limiting strips 212212 on the surface of the shaft 211 of the brushless motor 21.

[0050] In one embodiment, such as Figure 4-5As shown, the housing 10 is provided with a support groove 16, and the end of the shaft 211 is mounted in the support groove 16. Specifically, the support groove 16 can be used to install the shaft 211 of the brushless motor 21, providing support for the shaft 211 of the brushless motor 21, thereby preventing the shaft 211 from deforming, so as to ensure the stable meshing of the worm gear 40 and the gear transmission module 50.

[0051] Understandably, the gear transmission module 50 can have a gear shaft and a belt, with the gear shaft meshing with the worm gear 40 and the belt sleeved on the gear shaft and the output component 30.

[0052] In one embodiment, such as Figure 3 and 6 As shown, the gear transmission module 50 includes several stages of sequentially meshing transmission gears 51. Each stage of transmission gear 51 includes a large gear 511 and a small gear 512. The large gear 511 of the first stage transmission gear 51 meshes with the worm gear 40, and the small gear 512 of the last stage transmission gear 51 meshes with the output component 30. Each stage of transmission gear 51 meshes with the large gear 511 of the adjacent transmission gear 51 through the small gear 512. Specifically, when the worm gear 40 rotates, it drives the meshing first stage transmission gear 51 to rotate. Then, through the sequential transmission of each stage of gears, it finally drives the output component 30 to rotate, realizing the transmission of power to the output component 30. Since each stage of transmission gear 51 meshes with the large gear 511 of the adjacent transmission gear 51 through the small gear 512, each stage of gears can transmit speed reduction, thereby adaptively reducing the speed of the output component 30 according to actual needs, and thus better controlling the water valve.

[0053] In this embodiment, the number of transmission gears 51 is three stages. The first stage transmission gear 51 connected to the worm gear 40 is a plastic gear, the second and third stage transmission gears 51 are powder metallurgy gears, and the gears on the output component 30 are made of stainless steel.

[0054] Understandably, the transmission gears 51 at each stage can be directly rotatably connected to the housing 10.

[0055] In one embodiment, such as Figure 3 As shown, the housing 10 also has several rotating shafts 18, and each level of transmission gear 51 is rotatably connected to each rotating shaft 18. Specifically, by rotatably connecting the transmission gear 51 to the rotating shaft 18, contact between the transmission gear 51 and the housing 10 can be avoided, thereby improving transmission efficiency.

[0056] In this embodiment, the valve actuation device also includes a circuit board 60, such as Figure 3 As shown, the circuit board 60 is located on the upper side of the brushless motor 21 and is electrically connected to the brushless motor 21. The surface of the housing 10 is provided with a plug interface 17, which is connected to the circuit board 60 and is used for external control devices to plug in and control the brushless motor 21.

[0057] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below: During the process of driving the water valve opening, the external control device transmits the control signal to the circuit board 60. The circuit board 60 controls the brushless motor 21 to start, which drives the worm gear 40 to rotate. During the rotation of the worm gear 40, it drives each transmission gear 51 to rotate, which reduces the rotation speed of the worm gear 40 and transmits it to the output shaft. Finally, the power can be output through the output shaft to control the opening of the water valve. By setting the worm gear 40, while realizing the transmission of power from the drive component 20 to the water valve, the brushless motor 21 can also be placed horizontally inside the housing 10, thereby improving the compactness of the drive device and reducing the size of the drive device.

[0058] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
