Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a thermostat assembly and a vehicle. Background Technology

[0002] The thermostat assembly automatically adjusts the amount of coolant entering the radiator based on the coolant temperature, changing the coolant circulation range to regulate the cooling system's heat dissipation capacity and ensure the engine operates within a suitable temperature range. The thermostat must be kept in good working order; otherwise, it will seriously affect the normal operation of the engine.

[0003] Currently, after long-term use, thermostat assemblies on the market are prone to deviation due to repeated back-and-forth movement of the temperature control components, which can lead to the inability to completely close the main valve port and the auxiliary valve port. Utility Model Content

[0004] The main objective of this invention is to propose a thermostat assembly and vehicle that aims to increase the stability of the temperature control components during movement.

[0005] To achieve the above objectives, the thermostat assembly proposed in this utility model includes: A housing, comprising a mounting cavity, a liquid inlet, a first valve port, and a second valve port. A mounting bracket is provided within the mounting cavity to form a first cavity and a second cavity on both sides of the mounting bracket. The mounting bracket has a through-hole. The liquid inlet and the second valve port are formed in the second cavity, with the second valve port opposite to the through-hole. The liquid inlet communicates with both the second cavity and the second valve port. The first valve port is located on the cavity wall of the first cavity opposite to the mounting bracket. A temperature control component is movably mounted on the mounting bracket along the arrangement direction of the first cavity and the second cavity, so as to movably pass through the through-hole. The temperature control component controls the opening and closing of the first valve port and the second valve port according to the coolant temperature.

[0006] In one embodiment, the diameter of the first valve port is larger than the diameter of the second valve port, and the liquid outlet end of the second valve port is located on the outer peripheral surface of the housing.

[0007] In one embodiment, the temperature control assembly includes a wax cylinder, a push rod, a return spring, and a valve disposed at the end of the wax cylinder. The push rod is movably disposed inside the wax cylinder, with one end of the push rod extending out of the wax cylinder and fixed to the housing. The return spring is sleeved on the wax cylinder, with both ends of the return spring abutting against the mounting bracket and the valve, respectively. The valve is used to block the first valve port, and the wax cylinder is movably disposed through the through-hole to block the second valve port.

[0008] In one embodiment, the mounting bracket has a recessed portion facing the second cavity, and the reset spring portion is disposed within the recessed portion.

[0009] In one embodiment, the valve port edge of the second valve port is provided with guide ribs extending toward the mounting bracket, the guide ribs being used to guide the wax cylinder to seal the second valve port.

[0010] In one embodiment, the guide rib has a guide surface at one end near the mounting bracket, and the guide surface is inclined toward the outside of the second valve port in the direction near the mounting bracket.

[0011] In one embodiment, the guide rib includes a plurality of guide portions spaced circumferentially along the second valve port to form a communication port between any two of the guide portions, and the liquid inlet and the second valve port are connected through the communication port.

[0012] In one embodiment, the thermostat assembly further includes a valve seat, the liquid inlet and the second valve port are formed in the valve seat, and the valve seat is disposed in the second cavity.

[0013] In one embodiment, the valve seat is engaged within the second cavity.

[0014] This utility model also proposes a vehicle that includes the above-mentioned thermostat assembly.

[0015] The technical solution of this utility model involves setting a mounting bracket inside the mounting cavity of the housing, and movably mounting the temperature control component on the mounting bracket along the arrangement direction of the first cavity and the second cavity. It can be understood that the temperature control component is temperature-controlled. In this solution, the second valve port and the through-hole of the mounting bracket are arranged opposite each other, and the first valve port is located on the cavity wall opposite to the mounting bracket in the first cavity. This allows the temperature control component to move along the arrangement direction of the first cavity and the second cavity when the coolant temperature reaches the preset temperature, thus allowing the temperature control component to move through the through-hole, thereby controlling the opening and closing of the first and second valve ports. Therefore, the through-hole of this solution not only allows the temperature control component to pass through but also provides precise movement guidance, increasing the movement stability of the temperature control component and ensuring that the temperature control component stably closes the first or second valve port.

[0023] The thermostat assembly automatically adjusts the amount of coolant entering the radiator based on the coolant temperature, changing the coolant circulation range to regulate the cooling system's heat dissipation capacity and ensure the engine operates within a suitable temperature range. The thermostat must be kept in good working order; otherwise, it will seriously affect the normal operation of the engine.

[0024] Currently, after long-term use, thermostat assemblies on the market are prone to deviation due to repeated back-and-forth movement of the temperature control components, which can lead to the inability to completely close the main valve port and the auxiliary valve port.

[0025] This utility model proposes a thermostat assembly 10.

[0026] Please see Figure 1 and Figure 3 In one embodiment of this utility model, the thermostat assembly 10 includes a housing 100 and a temperature control component 300. The housing 100 has a mounting cavity 110, a liquid inlet 131, a first valve port 120, and a second valve port 132. A mounting bracket 200 is provided in the mounting cavity 110 to form a first cavity 111 and a second cavity 112 on both sides of the mounting bracket 200. The mounting bracket 200 has a through-hole. The liquid inlet 131 and the second valve port 132 are formed in the second cavity 112. The valve port 132 is arranged opposite to the through port, and the liquid inlet 131 is connected to the second cavity 112 and the second valve port 132 respectively. The first valve port 120 is provided on the cavity wall of the first cavity 111 opposite to the mounting bracket 200. The temperature control component 300 is movably provided on the mounting bracket 200 along the arrangement direction of the first cavity 111 and the second cavity 112 to movably pass through the through port. The temperature control component 300 controls the opening and closing of the first valve port 120 and the second valve port 132 according to the coolant temperature.

[0027] The technical solution of this utility model involves setting a mounting bracket 200 within the mounting cavity 110 of the housing 100, and movably mounting the temperature control component 300 on the mounting bracket 200 along the arrangement direction of the first cavity 111 and the second cavity 112. It can be understood that the temperature control component 300 is temperature-controlled. In this solution, the second valve port 132 and the through-hole of the mounting bracket 200 are arranged opposite each other, and the first valve port 120 is located on the cavity wall of the first cavity 111 opposite to the mounting bracket 200. This allows the temperature control component to activate when the coolant temperature reaches a preset temperature. The component 300 moves along the arrangement direction of the first cavity 111 and the second cavity 112, thereby allowing the temperature control component 300 to move through the through-hole, thereby achieving the effect of controlling the opening and closing of the first valve port 120 and the second valve port 132. It can be seen that the through-hole of this solution can not only allow the temperature control component 300 to pass through, but also provide precise movement guidance for the temperature control component 300, thus increasing the movement stability of the temperature control component 300 and ensuring that the temperature control component 300 stably closes the first valve port 120 or the second valve port 132.

[0028] In this embodiment, when the coolant temperature is low, the temperature control component 300 closes the first valve port 120 and opens the second valve port 132. When the coolant temperature gradually rises to a preset temperature (e.g., 80°C-95°C), the temperature control component 300 begins to move towards the second valve port 132 to open the first valve port 120 and close the second valve port 132, thereby increasing the amount of water entering the radiator and increasing the heat dissipation capacity of the cooling system. When the coolant temperature decreases, the temperature control component 300 closes the first valve port 120 again and opens the second valve port 132.

[0029] Optionally, in this embodiment, the diameter of the first valve port 120 is larger than the diameter of the second valve port 132, and the liquid outlet end of the second valve port 132 is located on the outer peripheral surface of the housing 100. It can be understood that by placing the liquid outlet end of the second valve port 132 on the outer peripheral surface of the housing 100, side bypass can be achieved, greatly simplifying the structure of the housing 100 and making the pipeline arrangement more flexible, thereby saving arrangement space. Of course, this solution is not limited to this; in other embodiments, the liquid outlet end of the second valve port 132 can also be located on the cavity wall of the second cavity 112 facing the mounting bracket 200.

[0030] The diameter of the first valve port 120 is larger than the diameter of the second valve port 132. That is, the first valve port 120 is the main valve port and the second valve port 132 is the auxiliary valve port.

[0031] Reference Figure 2 and Figure 4Optionally, in this embodiment, the temperature control component 300 includes a wax cylinder 310, a push rod 320, a return spring 330, and a valve 340 disposed at the end of the wax cylinder 310. The push rod 320 is movably disposed inside the wax cylinder 310, with one end of the push rod 320 extending out of the wax cylinder 310 and fixed to the housing 100. The return spring 330 is sleeved on the wax cylinder 310, with both ends of the return spring 330 abutting against the mounting bracket 200 and the valve 340, respectively. The valve 340 is used to block the first valve port 120, and the wax cylinder 310 is movably disposed through the through-hole to block the second valve port 132. This solution utilizes the body of the wax cylinder 310 to open or close the second valve port 132. Compared with the existing thermostat assembly 10, the auxiliary valve used to open or close the second valve port 132 is eliminated. At the same time, the auxiliary spring, retaining ring, and tail rod can be eliminated, saving assembly process time and cost as well as the cost of the parts themselves. Of course, this solution is not limited to this. In other embodiments, the temperature control component 300 may also include a temperature sensor, a valve body, and a control device. The temperature sensor is located in the mounting cavity 110 and is used to detect the temperature of the coolant. The control device is electrically connected to the temperature sensor and the valve body respectively. When the coolant temperature reaches the preset temperature, the temperature sensor transmits a signal to the control device, and the control device controls the valve body to move in order to control the opening and closing of the first valve body and the second valve body.

[0032] It should be noted that when the temperature control component 300 is configured as a wax-type temperature sensing component (i.e., equipped with a wax cartridge), the preset temperature refers to the melting temperature of the wax. However, when the temperature control component is configured as an electronic temperature sensing component (i.e., equipped with a temperature sensor, electronic control device, valve body, etc.), the preset temperature is the set coolant temperature. When the coolant temperature reaches the preset temperature, the valve body is controlled to move.

[0033] Specifically, when the engine is warmed up, that is, when the coolant temperature is low, valve 340 blocks the large valve port, and the large circulation is closed. The coolant enters from the engine outlet through the inlet 131 of the thermostat assembly 10 into the first chamber 111 and the second chamber 112, then enters the second valve port 132, and subsequently enters the bypass pipe through the outlet of the second valve port 132, forming a small circulation. As the engine coolant temperature rises, when it reaches the preset temperature of the temperature control component 300 (i.e., the melting temperature of the paraffin wax in the wax cylinder 310), the wax in the temperature-sensing wax cylinder 310 melts and expands, thereby pushing the push rod 320. Since the push rod 320 is fixed to the housing 100 and cannot move, a reaction force is applied to the wax cylinder 310, causing it to move away from the push rod 320. That is, the wax cylinder 310 moves towards the second valve port 132 to pass through the through hole and enter the second valve port 132 to seal it, at which point the small circulation is closed. At the same time, the valve 340 moves together with the wax cylinder 310 towards the second valve port 132, thereby opening the first valve port 120, allowing coolant to enter from the inlet 131 into the first chamber 111 and the second chamber 112, and then into the first valve port 120, forming a large circulation. It can be understood that the higher the temperature, the larger the opening of the first valve port 120. When the coolant temperature is low, the return spring 330 pushes the wax cylinder 310 toward the first valve port 120, thereby resealing the first valve port 120 and opening the second valve port 132.

[0034] Furthermore, in one embodiment, the mounting bracket 200 is provided with a recess 210 recessed towards the second cavity 112, and the return spring 330 is partially disposed within the recess 210. The recess 210 allows for a more compact structure of the thermostat assembly 10, and also limits the movement of the return spring 330. Of course, this solution is not limited to this; in other embodiments, the recess 210 may not be provided on the mounting bracket 200.

[0035] Optionally, in this embodiment, the valve port edge of the second valve port 132 is provided with a guide rib 133 extending toward the mounting bracket 200. The guide rib 133 is used to guide the wax cylinder 310 to seal the second valve port 132. The arrangement of the guide rib 133 can guide the wax cylinder 310 to seal the second valve port 132, further preventing the wax cylinder 310 from deviating from the second valve port 132, thus preventing the wax cylinder 310 from being unable to close the second valve port 132. Of course, this solution is not limited to this. In other embodiments, a guide channel can also be provided on the side of the through hole near the second valve port 132 to guide the wax cylinder 310 to seal the second valve port 132.

[0036] Furthermore, the guide rib 133 has a guide surface 133a at one end near the mounting bracket 200, and the guide surface 133a is inclined towards the outside of the second valve port 132 in the direction near the mounting bracket 200; such a guide structure is simple and easy to manufacture. Of course, this solution is not limited to this. In other embodiments, the guide rib 133 may also include an insertion section and a guide section connected in sequence, the guide section being connected to the second valve port 132, the diameter of the insertion section being larger than the diameter of the second valve port 132, and the diameter of the guide section gradually decreasing in the direction from the insertion section to the second valve port 132.

[0037] In this embodiment, the guide rib 133 includes multiple guide portions 133b spaced circumferentially along the second valve port 132, forming a connecting port 134 between any two guide portions 133b. The liquid inlet 131 and the second valve port 132 are connected through the connecting port 134. This facilitates the connection between the liquid inlet 131 and the second valve port 132. Furthermore, positioning the connecting port 134 circumferentially around the second valve port 132 prevents the mounting bracket and the second valve port 132 from being too close together, thus avoiding interference with the liquid inlet of the second valve port 132 by the mounting bracket 200. Of course, this solution is not limited to this. In other embodiments, the guide rib 133 may also be arranged as annular guide ribs, with the edges of the mounting bracket 200 and the second valve port 132 spaced apart.

[0038] Reference Figure 3 and Figure 4 Optionally, in one embodiment, the thermostat assembly 10 further includes a valve seat 130, with an inlet 131 and a second valve port 132 formed on the valve seat 130, and the valve seat 130 disposed in the second cavity 112. It is understood that the valve seat 130 facilitates the forming of the second valve port 132 and the inlet 131, which helps reduce manufacturing complexity. Of course, this solution is not limited to this. In other embodiments, the housing 100 includes a first housing portion and a second housing portion connected together, with the first cavity 111 formed on the first housing portion, the second cavity 112 formed on the second housing portion, and the inlet 131 and the second valve port 132 formed on the second housing portion.

[0039] The valve seat 130 is provided with a liquid guiding channel, which includes a first liquid guiding section and a second liquid guiding section that are vertically connected. The first liquid guiding section extends from the second cavity 112 to the first cavity 111, and the second cavity 112 extends laterally toward the housing 100. The liquid inlet section of the second valve port 132 is formed at the end of the first liquid guiding section away from the second liquid guiding section, and the liquid outlet section of the second valve port 132 is formed at the end of the second liquid guiding section away from the first liquid guiding section.

[0040] Optionally, in one embodiment, the valve seat 130 is snapped into the second cavity 112, which facilitates the installation and removal of the valve seat 130, thereby improving the installation and removal efficiency of the thermostat assembly 10. Of course, this solution is not limited to this; in other embodiments, the valve seat 130 may also be threadedly connected to the second cavity 112.

[0041] Furthermore, the valve seat 130 is secured within the second cavity 112 via an inverted snap-fit ​​structure. This inverted snap-fit ​​structure facilitates installation; installation can be completed simply by pushing the valve seat 130 towards the first cavity 111, thus significantly improving installation efficiency. Of course, this solution is not limited to this; in other embodiments, the valve seat 130 can also be interference-fitted and secured within the second cavity 112.

[0042] In this embodiment, the valve seat 130 has elastic buckles on both opposite sides, and the housing 100 has corresponding slots for the elastic buckles, with the elastic buckles engaging within the slots. The elastic buckles make installing the valve seat 130 easier. However, this solution is not limited to this; in other embodiments, the housing 100 may have a protruding part, and the valve seat 130 may have a slot, with the protruding part engaging within the slot.

[0043] Furthermore, in this embodiment, the mounting bracket 200 is snapped onto the housing 100, which facilitates the installation and removal of the mounting bracket 200, thereby facilitating the installation and removal of the temperature control component 300 and improving the efficiency of the thermostat assembly 10. Of course, this solution is not limited to this; in other embodiments, the mounting base can also be screwed into the housing 100.

[0044] Furthermore, the mounting bracket 200 has snap-fit ​​flanges on both sides, and the housing 100 has a snap-fit ​​groove corresponding to each of the two snap-fit ​​flanges, with the snap-fit ​​flanges snapping into the snap-fit ​​grooves. Of course, this solution is not limited to this. In other embodiments, the mounting bracket 200 is provided with elastic buckles, and the mounting housing is provided with snap-fit ​​holes, with the elastic buckles snapping into the snap-fit ​​holes.

[0045] This utility model also proposes a vehicle that includes a thermostat assembly. The specific structure of the thermostat assembly is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
