Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermostat technology, and more specifically to a thermostat seat assembly. Background Technology
[0002] The thermostat in a car, often called a car temperature control valve or heater thermostat, is mainly used to control the temperature of the engine cooling system. Its function is to regulate the flow of coolant, thereby affecting the temperature of the engine and the car's heating system.
[0003] Currently, in the operation of existing thermostats, when the water temperature has not reached the thermostat's peak value, the main valve and bypass valve of the thermostat are not fully open or closed. At this time, coolant will pass through both the main valve and the bypass valve at the same time. However, when the temperature fluctuates, the opening and closing size of the main valve and bypass valve of the thermostat will be constantly changing, which will cause the coolant flow to change accordingly, thereby affecting the engine's heat dissipation efficiency and the stability of the engine's operating temperature. Therefore, it is urgent to design a thermostat seat assembly to solve the above problems. Utility Model Content

[0005] This utility model provides the following technical solution: a thermostat seat assembly, including a frame assembly and an adjustment assembly disposed inside the frame assembly, further including a first closing assembly disposed at the bottom of the adjustment assembly and a second closing assembly disposed inside the adjustment assembly, the adjustment assembly including an adjustment cylinder, the adjustment cylinder being provided with a first adjustment chamber, a second adjustment chamber and a third adjustment chamber, the first adjustment chamber, the second adjustment chamber and the third adjustment chamber being filled with filler, the second adjustment chamber being provided with a first sleeve, the third adjustment chamber being provided with a second sleeve, the first closing assembly including a main shaft disposed in the adjustment cylinder, the main shaft being respectively provided with a first lifting head, a second lifting head and a third lifting head, a main valve being rotatably connected to the top of the adjustment cylinder, and a main spring being provided on the outer wall of the adjustment cylinder.
[0006] Furthermore, the bottom of both the second and third lifting heads is fixedly connected with an extension rod, which is inserted into the top of the first and second lifting heads respectively.
[0007] Furthermore, the frame assembly includes a frame body, with a limit bracket and a support frame fixedly connected to the top and bottom of the frame body, respectively. A support ring is fixedly connected between the support frames, and an adjusting cylinder is sleeved inside the support ring.
[0008] Furthermore, the main shaft is rotatably connected to the bottom of the limiting bracket, and multiple first blades are fixedly connected to the outer circumference of the top of the main shaft. Multiple first balls are rotatably connected to the top of the first lifting head, the second lifting head, and the third lifting head.
[0009] Furthermore, the first closing component includes a bypass valve, a sleeve is fixedly connected to the bottom of the regulating cylinder, the bypass valve is sleeved on the outer wall of the sleeve, and a secondary spring is fixedly connected between the bypass valve and the regulating cylinder.
[0010] Furthermore, a rotating shaft is fixedly connected to the bottom of the adjusting cylinder, the rotating shaft is inserted into the sleeve, and multiple second blades are fixedly connected to the outer circumference of the bottom of the rotating shaft.
[0011] Furthermore, a plurality of second ball bearings are rotatably connected to the top of the regulating cylinder, and all the second ball bearings are in contact with the main valve.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] This invention, by setting up a first adjustment chamber, a second adjustment chamber, and a third adjustment chamber, allows the filling material in the first, second, and third adjustment chambers to expand sequentially under different temperatures when the adjustment cylinder comes into contact with the coolant. Under the action of the first, second, and third lifting heads, the opening and closing size of the main valve is adjusted sequentially, and the opening and closing size of the main valve and the bypass valve can be kept stable within a certain temperature range, thereby achieving a step-by-step incremental adjustment effect on the opening and closing size.

Since the extension rod is elliptical, it can drive the first lifting head, the second lifting head and the third lifting head to rotate at the same time, preventing the filler from adhering to the outer wall of the first lifting head, the second lifting head and the third lifting head when it cools and solidifies.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0022] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 5 The present invention will be further described below.
[0023] A thermostat seat assembly includes a frame assembly 1 and an adjustment assembly 2 disposed inside the frame assembly 1. It also includes a first closing assembly 3 disposed at the bottom of the adjustment assembly 2 and a second closing assembly 4 disposed inside the adjustment assembly 2. The adjustment assembly 2 includes an adjustment cylinder 201, which contains a first adjustment chamber, a second adjustment chamber, and a third adjustment chamber. Each of the first, second, and third adjustment chambers is filled with a filler material 202. A first sleeve 203 is disposed in the second adjustment chamber, and a second sleeve 204 is disposed in the third adjustment chamber. The first closing assembly 3 includes a main shaft 402 disposed in the adjustment cylinder 201. A first lifting head 406, a second lifting head 405, and a third lifting head 404 are respectively disposed on the main shaft 402. A main valve 401 is rotatably connected to the top of the adjustment cylinder 201, and a main spring 205 is disposed on the outer wall of the adjustment cylinder 201.
[0024] In this embodiment, since the first, second, and third regulating chambers are all filled with filler material 202, and the second regulating chamber is provided with a first sleeve 203 and the third regulating chamber is provided with a second sleeve 204, the second sleeve 204 being thicker than the first sleeve 203, when the regulating cylinder 201 comes into contact with the coolant, the filler material 202 in the first regulating chamber will first expand due to heat, pushing the first lifting head 406 along with the main shaft 402 upwards, thereby driving the entire regulating cylinder 201 and the second closing assembly 4 downwards, and stabilizing the opening and closing size of the second closing assembly 4 at the position where the first lifting head 406 contacts the first regulating chamber. As the coolant temperature rises... As the temperature gradually increases, the filler 202 in the second regulating chamber also begins to expand due to heat, causing the second lifting head 405 to rise, further expanding the opening and closing size of the second closing component 4, and stabilizing the opening and closing size at the position where the second lifting head 405 contacts the second regulating chamber. Finally, as the coolant temperature rises again, the filler 202 in the third regulating chamber also begins to expand due to heat, causing the third lifting head 404 to rise, further expanding the opening and closing size of the second closing component 4, and stabilizing the opening and closing size at the position where the third lifting head 404 contacts the third regulating chamber. This achieves a step-by-step increasing adjustment effect on the opening and closing size, and keeps the opening and closing size stable within a certain temperature range.
[0025] Specifically, the bottom of the second lifting head 405 and the third lifting head 404 are both fixedly connected with extension rods 408, which are respectively inserted into the top of the first lifting head 406 and the second lifting head 405.
[0026] In this embodiment, the second lifting head 405 rises and falls above the first lifting head 406 under the action of the extension rod 408, and the third lifting head 404 rises and falls above the second lifting head 405 under the action of the extension rod 408. The extension rods 408 are all elliptical.
[0027] Specifically, the frame assembly 1 includes a frame body 101, with a limit bracket 102 and a support frame 103 fixedly connected to the top and bottom of the frame body 101, respectively. A support ring 104 is fixedly connected between the support frames 103, and an adjusting cylinder 201 is sleeved inside the support ring 104.
[0028] In this embodiment, when the adjusting cylinder 201 is raised or lowered, the support ring 104 will limit the adjusting cylinder 201.
[0029] Specifically, the main shaft 402 is rotatably connected to the bottom of the limiting bracket 102, and multiple first blades 403 are fixedly connected to the outer circumference of the top of the main shaft 402. Multiple first balls 407 are rotatably connected to the top of the first lifting head 406, the second lifting head 405 and the third lifting head 404.
[0030] In this embodiment, when the coolant temperature rises, causing the regulating cylinder 201 and the main valve 401 to move downwards, some coolant will flow out from between the main valve 401 and the frame body 101. When the flowing coolant impacts the first blade 403, it will drive the first blade 403 and the main shaft 402 to rotate. Since the extension rod 408 is elliptical, it can drive the first lifting head 406, the second lifting head 405, and the third lifting head 404 to rotate simultaneously, preventing the filler 202 from adhering to the outer walls of the first lifting head 406, the second lifting head 405, and the third lifting head 404 when it cools and solidifies. When the first lifting head 406, the second lifting head 405, and the third lifting head 404 rotate, the friction experienced by the first lifting head 406, the second lifting head 405, and the third lifting head 404 will be reduced under the action of the first ball 407, thus promoting rotation.
[0031] Specifically, the first closing component 3 includes a bypass valve 301, a sleeve is fixedly connected to the bottom of the regulating cylinder 201, the bypass valve 301 is sleeved on the outer wall of the sleeve, and a secondary spring 302 is fixedly connected between the bypass valve 301 and the regulating cylinder 201.
[0032] In this embodiment, when the coolant temperature is low and the filler 202 has not expanded due to heat, the coolant will flow downward through the bypass valve 301. When the coolant temperature rises and the filler 202 expands, causing the first closing component 3 to descend, the bypass valve 301 will gradually reduce the distance between itself and the valve, and squeeze the secondary spring 302, thereby closing the bypass valve 301.
[0033] Specifically, a rotating shaft 303 is fixedly connected to the bottom of the adjusting cylinder 201. The rotating shaft 303 is inserted into the sleeve, and multiple second blades 304 are fixedly connected to the outer circumference of the bottom of the rotating shaft 303.
[0034] In this embodiment, when the coolant flows downward through the bypass valve 301, the coolant impacting the second blade 304 will drive the rotating shaft 303 to rotate. Since the regulating cylinder 201 is fixedly connected to the top of the rotating shaft 303, the regulating cylinder 201 will gradually rotate, causing the filler 202 in the first regulating chamber, the second regulating chamber, and the third regulating chamber to move away from the first lifting head 406, the second lifting head 405, and the third lifting head 404 under the action of centrifugal force. This further prevents the filler 202 from adhering to the outer wall of the first lifting head 406, the second lifting head 405, and the third lifting head 404 when it cools and solidifies.
[0035] Specifically, multiple second ball bearings 409 are rotatably connected to the top of the regulating cylinder 201, and all the second ball bearings 409 are in contact with the main valve 401.
[0036] In this embodiment, when the regulating cylinder 201 rotates, the friction between the main valve 401 and the regulating cylinder 201 can be reduced under the action of the second ball 409, preventing the regulating cylinder 201 from failing to rotate normally.
[0037] Working principle: When the regulating cylinder 201 comes into contact with the coolant, the filler 202 in the first regulating chamber will first expand due to heat, pushing the first lifting head 406 along with the main shaft 402 upward, thereby driving the entire regulating cylinder 201 and the second closing assembly 4 downward. As the coolant temperature gradually rises, the filler 202 in the second regulating chamber also begins to expand due to heat, driving the second lifting head 405 upward, further expanding the opening and closing size of the second closing assembly 4. As the coolant temperature rises again, the filler in the third regulating chamber... As object 202 heats up and expands, it causes the third lifting head 404 to rise, further widening the opening and closing size of the second closing assembly 4. When the coolant temperature rises, causing the regulating cylinder 201 and the main valve 401 to move downwards, some coolant will flow out from between the main valve 401 and the frame body 101. When the flowing coolant impacts the first blade 403, it will cause the first blade 403 and the main shaft 402 to rotate. Since the extension rod 408 is elliptical, it can drive the first lifting head 406 and the second lifting head 405 to rotate. The first lifting head 406, the second lifting head 405, and the third lifting head 404 rotate simultaneously to prevent the filler 202 from adhering to the outer walls of the first lifting head 406, the second lifting head 405, and the third lifting head 404 when it cools and solidifies. Under the action of the first ball bearing 407, the friction experienced by the first lifting head 406, the second lifting head 405, and the third lifting head 404 is reduced. When the coolant temperature is low and the filler 202 has not expanded due to heat, the coolant will flow downward through the bypass valve 301. When the coolant temperature rises, the filler 202 expands, causing the first closing group to... When component 3 descends, the bypass valve 301 gradually reduces the distance between itself and the valve, and squeezes the secondary spring 302, thereby closing the bypass valve 301. When the coolant flows down through the bypass valve 301, the coolant impacting the second blade 304 will drive the rotating shaft 303 to rotate, and the regulating cylinder 201 will gradually rotate, causing the filling material 202 in the first regulating chamber, the second regulating chamber, and the third regulating chamber to move away from the first lifting head 406, the second lifting head 405, and the third lifting head 404 under the action of centrifugal force.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
