Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0067] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0068] In the following, in conjunction with the accompanying drawings, a motor thermostat that is easy to control provided by an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0069] Embodiment 1:

[0070] like Figures 1 to 6 As shown, the embodiment of the present application provides a motor thermostat that is easy to control, including a housing 1, a heat dissipation main pipe 2, a heat dissipation branch pipe 3, an active opening and closing component 4 (composed of a frame 401, a valve plate 402, and a driving component 403) and a passive opening and closing component 5, and also includes: a friction roller 6, which is fixedly connected to the driving component; an automatic reversing unit 7, which is movably installed on the frame 401;

[0071] Furthermore, the automatic reversing unit 7 includes a movable seat 701, which is movably installed in the inner cavity of the frame body 401; a support column 702, which is rotatably installed on the movable seat 701; a pair of connecting frames 703, which are respectively fixedly connected to the lower ends of the support columns 702; a clamping wheel 704, which is rotatably connected between the pair of connecting frames 703 and is frictionally connected with the friction wheel; a swing block 705, which is fixedly installed at the upper end of the support column 702; an installation cavity 706, which is arranged at the upper end of the step surface of the movable seat 701; an automatic telescopic rod 707, which is fixedly installed on one side inner wall of the installation cavity 706; a guide block 708, which is fixedly connected to the output end of the automatic telescopic rod 707; wherein, one side of the swing block 705 is in contact with the outer end of the guide block 708, and the driving assembly drives the friction roller 6 to rotate.

[0072] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the temperature sensing control component 4032 is installed on the housing 1, and the temperature sensor of the temperature sensing control component 4032 detects the temperature of the internal cooling water and transmits the detected signal to the engine control module. The engine control module sends a signal to the motor 4031, so that the motor 4031 drives the gear set to drive, and the gear set drives the friction roller 6 to rotate. The friction roller 6 rotates and drives the clamping wheel 704 in contact with the upper end to rotate. The friction roller 6 and the clamping wheel 704 are driven by friction, and the clamping wheel 704 is driven by friction. 04 moves along the axial direction of the friction roller 6, the movable seat 701 supporting the clamping wheel 704 is located in the cavity of the frame 401, and the movable seat 701 is connected to the rack column 901 through the connecting block 11, and the rack column 901 is installed on the fixed seat 8, and the fixed seat 8 is arranged on the inner wall of one side of the frame 401. Therefore, in the process of the clamping wheel 704 moving along the friction wheel, the frame 401 is also driven to move in the inner cavity of the shell 1. When the frame 401 moves, the connecting port on the valve plate 402 installed on the inner side is opened / closed with the heat dissipation branch pipe 3, thereby controlling the engine cooling water circulation. When controlling the flow of coolant, it is necessary to control the movement of the frame 401. The driving direction of the frame 401 is also adjusted by the driving direction of the clamping wheel 704. When the clamping wheel 704 changes direction, the automatic telescopic rod 707 in the mounting cavity 706 at the upper end of the movable seat 701 drives the guide block 708 to move inward, and the tip of the swing block 705 swings along the outer wall of the guide block 708, so that the swing block 705 drives the support column 702 to rotate, and the support column 702 drives the clamping wheel 704 to turn through a pair of connecting frames 703, thereby changing the driving direction of the clamping wheel 704 along the friction roller 6, ensuring the automatic reversal of the clamping wheel 704, and changing the driving direction of the frame 401 without adjusting the rotation direction of the output shaft of the motor 4031.

[0073] Embodiment 2:

[0074] like Figures 2 to 7As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a fixed seat 8, which is arranged in the frame 401; a clamping assembly 9, which is adjustably mounted on the fixed seat 8; wherein the clamping assembly 9 is fixedly connected to the movable seat 701, and is used to drive the movable seat 701 to move up and down.

[0075] Furthermore, the clamping assembly 9 includes a rack column 901, which is movably installed in the inner cavity of the fixed base 8; a support frame 902, which is installed in the fixed base 8 through fasteners, and the rack column 901 is located in the support frame 902; a turntable 903, which is rotatably connected to one side of the support frame 902; a protrusion 904, which is spirally arranged on the back side of the turntable 903; and a handle 905, which is fixedly installed on the front side of the turntable 903; wherein the protrusion 904 cooperates with the teeth of the rack column 901.

[0076] Furthermore, it also includes a slide groove 10, which is arranged on the inner side of the fixed seat 8; a connecting block 11, which is slidably installed in the slide groove 10 and fixedly connected between the rack column 901 and the movable seat 701.

[0077] In this embodiment of the present application, due to the adoption of the above-mentioned structure, in order to ensure the friction between the pressure wheel 704 and the friction roller 6 during the driving process, a pressure assembly 9 is provided on the frame 401 to ensure the pressure effect of the pressure wheel 704, and the fixed seat 8 is provided on the inner wall of the frame 401. The pressure assembly 9 can be adjustably installed on the fixed seat 8. A rack column 901 is inserted in the inner cavity of the fixed seat 8. The rack end of the rack column 901 is meshed with the inner side of the rotating disk 903. The connecting end of the rack column 901 is fixedly connected to the movable seat 701 through the connecting block 11. The rotating disk 903 is fixed through the supporting frame 902. When the height of the pressure wheel 704 needs to be adjusted, the handle 90 5 is used to adjust the rotation direction of the turntable 903. When the turntable 903 rotates, the protrusion 904 on the inner side of the turntable 903 meshes with the teeth of the rack column 901. Since the protrusion 904 is spirally arranged, during the rotation of the turntable 903, the teeth of the rack column are driven along the spiral trend of the protrusion 904, so that the rack column can move up and down. During the movement of the rack column, the connecting block 11 moves along the slide groove 10, and the connecting block 11 drives the movable seat 701 to move inside the frame 401, thereby changing the height of the clamping wheel 704, facilitating manual adjustment of the height of the clamping wheel 704, and ensuring the friction between the clamping wheel 704 and the friction roller 6 during the driving process.

[0078] Embodiment 3:

[0079] like Figure 8 , Fig. 9As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: the driving component 403 includes a motor 4031, which is fixedly mounted on the shell 1; a temperature sensing control component 4032, which is mounted on the shell 1 and controls the opening and closing of the motor 4031; wherein the motor 4031 is connected to the friction roller 6 through a gear set.

[0080] Furthermore, it also includes a driving gear 12, which is the first one of the gear group connected to the motor 4031; a driving shaft 13, which is fixedly connected to the output end of the motor 4031; an outer ring sleeve 14, which is fixedly sleeved on the inner wall of the driving gear 12; and an inner ring sleeve 15, which is sleeved on the driving shaft 13; wherein the outer ring sleeve 14 is slidably sleeved outside the inner ring sleeve 15.

[0081] Furthermore, it also includes a controller 16, which is installed in the blind hole of the driving shaft 13; a telescopic rod 17, which is fixedly connected to the controller 16; a through hole 18, which is arranged on the inner ring sleeve 15 and extends to the outer end of the paper outer ring sleeve 14; a limiting hole 19, which is arranged on the inner wall of the driving gear 12 and corresponds to the position of the through hole 18; wherein the telescopic rod 17 is slidably connected to the limiting hole 19 through the through hole 18; the outer end face of the telescopic rod 17 has the same curvature as the inner wall of the inner ring sleeve 15, and the outer end face of the telescopic rod 17 has the same curvature as the bottom surface of the limiting hole 19.

[0082] In this embodiment of the present application, due to the adoption of the above structure, the motor 4031 drives the gear set to drive the friction roller 6 to rotate, and the gears between the gear sets are meshed and transmitted. When used for a long time, the gear friction produces debris, which easily causes the gear set to jam. During the jamming process, the drive shaft 13 stops rotating, but the motor 4031 still outputs, and the motor 4031 is easily damaged. In order to avoid damage to the motor 4031, the inner ring sleeve 15 and the outer ring sleeve 14 are slidably connected between the drive shaft 13 and the driving gear 12. In the normal driving state, the telescopic rod 17 is in an extended state, and the outer end face of the telescopic rod 17 passes through the inner ring sleeve 15 and the outer ring sleeve 14 along the through hole 18 in sequence, and enters the limiting hole 19 of the driving gear 12. At the same time, the outer end face of the telescopic rod 17 contacts the bottom end of the limiting hole 19, and the telescopic rod 17 extends into the limiting hole 19, so that the drive shaft 13, the ball bearing 14 and the driving gear 12 are fixed together to ensure that the motor 4031 drives the gear set to operate; when the jamming state, the inspection The detector transmits the stuck signal to the controller 16, and the controller 16 controls the telescopic rod 17 to contract, and the outer end surface of the telescopic rod 17 is separated from the limiting hole 19. At the same time, the outer end surface of the telescopic rod 17 is on the same arc surface as the inner wall of the inner ring sleeve 15, and the telescopic rod 17 is no longer in contact with the bottom surface of the limiting hole 19. When the telescopic rod 17 is separated from the limiting hole 19, the drive shaft 13 and the active gear 12 are rotatably connected through the inner ring sleeve 15 and the outer ring sleeve 14. When stuck, the active gear 12 stops rotating, but the drive shaft 13 can still rotate, and the drive shaft 13 does not produce a stall, thereby avoiding the phenomenon of damage to the motor 4031.
