Description

Technical Field

[0001] This utility model mainly relates to the technical field of automotive thermostats, specifically a novel thermostat claw reinforcement structure. Background Technology

[0002] An automotive thermostat is a valve that controls the flow path of engine coolant. This product automatically adjusts the amount of water entering the radiator according to the coolant temperature to ensure that the engine operates within a suitable temperature range, which can save energy. The thermostats used in engines are mainly wax thermostats, which use the paraffin wax inside to control the coolant circulation through the principle of thermal expansion and contraction.

[0003] The thermostat clip structure is a bracket used to install and position the thermostat. Existing brackets are mostly made of metal, which provides sufficient strength but is costly. Replacing them with plastic materials would reduce structural strength, for example, [the following text appears to be unrelated and possibly a separate sentence fragment: "attached Figure 5 As shown, the claw has a through-type structure. The original design is only suitable for metal materials and not for plastic molding materials. If the plastic claw with the original design is used, there is a risk of cracks and breakage after long-term use. Since the cost of metal materials is high, it cannot achieve the company's goal of reducing costs and increasing efficiency. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model provides a novel thermostat claw reinforcement structure to solve the technical problem mentioned in the background that if the metal thermostat claws are replaced with plastic or through-type structures without changing the design structure, the claws will not be strong enough and will easily crack or break during use.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A novel thermostat claw reinforcement structure includes a housing and a thermostat structure mounted on the housing. A heating rod and two claws are disposed at the center of the housing, with the two claws located on both sides of the heating rod. Each claw is provided with a semi-enclosed slot, and the two semi-enclosed slots are symmetrical about the heating rod. Each semi-enclosed slot is provided with a first groove and a second groove, with the second groove located on the upper side of the end of the corresponding semi-enclosed slot.

[0007] Furthermore, an interface is provided on one side of the outer wall of the housing, and two connectors are provided in the interface, each of which is provided with a pin.

[0008] Furthermore, the nodule thermostat structure includes a wax pack, and the wax pack is fitted onto the heating rod.

[0009] Furthermore, from top to bottom, the wax package is provided with a secondary valve disc, a secondary spring, a bracket, a main spring, and a main valve disc, with the main valve disc located at the opening on the upper side of the housing.

[0010] Furthermore, both sides of the bracket are provided with folded edges, and each folded edge engages with the corresponding first groove and second groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention optimizes the structural design of the thermostat's claw by incorporating a housing, heating rod, claws, a semi-enclosed slot, a first groove, a second groove, and an interface. The use of a contour-following claw design ensures a tight fit between the semi-enclosed slot and the folded edges on both sides of the bracket.

[0013] Without increasing costs or incorporating complicated designs, this plastic component ensures structural strength and represents a qualitative improvement over traditional plastic designs. It eliminates the risk of cracks or breakage after prolonged use, making the plastic structure more robust and thus replacing the original metal solution. This achieves cost reduction and efficiency improvement, demonstrating practical value and market potential.
