[0031] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0032] The utility model provides a sliding valve type thermostat assembly, comprising:

[0033] The valve assembly is a cylindrical structure, with a temperature sensing package inserted at one end of the valve assembly and a spring inserted at the other end of the valve assembly;

[0034] The valve seat is a cylindrical structure. The other end of the valve assembly and the spring are embedded in one end of the valve seat. Both ends of the spring are squeezed by the valve assembly and the valve seat.

[0035] Specifically, the thermostat assembly compresses and secures the spring through the valve assembly and valve seat, while the temperature-sensing bulb is secured solely by the valve assembly. When the ambient temperature fluctuates, the bulb applies varying pressures to the valve assembly, which in turn compresses the spring through the valve assembly, causing the thermostat assembly to alter the coolant flow path. The entire thermostat assembly eliminates the original base and eliminates the riveting process during production, reducing costs.

[0036] Optionally, a boss is provided on the inner periphery of one end of the valve assembly, and one side of the boss is in contact with a raised portion on the outer periphery of the temperature sensing package.

[0037] Optionally, a cavity is formed between the inner side of one end of the valve assembly and the outer side of the temperature-sensing package, and one end of the spring is embedded in the cavity.

[0038] Specifically, the valve assembly is fixed by the boss and the protrusion of the temperature-sensing package, so that the valve assembly and the temperature-sensing package form an annular cavity along the circumferential direction on the other side of the boss, which facilitates the positioning and installation of the spring and ensures that the spring is accurately installed in the radial direction.

[0039] Optionally, the other side of the boss fits with one end of the spring.

[0040] Specifically, after the valve assembly and the temperature-sensing package are installed in place, the spring is inserted from the other end of the valve assembly into the interior of the valve assembly until the end of the spring touches the other side of the boss. This ensures that the spring is installed in place in the axial direction.

[0041] Optionally, one end of the valve seat is provided with multiple notches along the circumferential direction, the valve seat is provided with an inner boss on the tube wall between adjacent notches, and the other end of the valve assembly is provided with an outer boss, and the inner boss and the outer boss are engaged with each other.

[0042] Specifically, the valve seat and the valve assembly are fixed by the mutual engagement of the inner boss and the outer boss. An annular outer boss is circumferentially provided at the other end of the valve assembly, and since the valve seat has a notch, a plurality of discontinuous inner bosses are formed circumferentially at only one end of the valve seat. When the valve assembly is embedded in the valve seat, a spring is present between the valve assembly and the valve seat. Under the action of the spring, the valve assembly can be pushed toward the outside of the valve seat, so that the inner and outer bosses form an inverted hook for fixation.

[0043] Optionally, a plurality of stops are provided along the circumferential direction at the other end of the valve seat, and the stops fit against the end surface of the spring.

[0044] Specifically, a plurality of blocks are provided at the end of the valve seat for supporting the spring to ensure that the valve assembly is always subjected to the force of the spring, so that the valve assembly and the valve seat can be locked into place with each other.

[0045] Optionally, the stopper and the notch are arranged correspondingly.

[0046] Specifically, the block and the notch are staggered, which can ensure that the block has sufficient strength to support the spring and avoid the overall strength of the valve seat being reduced due to the block and the notch being provided at both ends of the valve seat.

[0047] Optionally, the material of the valve seat is thermoplastic plastic material.

[0048] Optionally, the material of the valve assembly consists of thermoplastic material and rubber material.

[0049] Specifically, the valve seat and most of the valve assembly are made of plastic materials, which can effectively control the economic cost of accessories. When assembling the thermostat assembly, the valve assembly can be squeezed and deformed, so that the valve assembly and spring can be inserted into the valve seat. Then, the valve assembly can be released to achieve mutual engagement between the valve assembly and the valve seat.

[0050] The utility model also provides an automobile, comprising the above-mentioned sliding valve type thermostat assembly.
