Description

Technical Field

[0001] This utility model mainly relates to the field of thermostat technology, specifically a semi-enclosed hook structure for a plastic shell thermostat. Background Technology

[0002] In gasoline-powered vehicles, the thermostat is the component that controls the large and small circulation cycles of the engine cooling system. Its performance directly affects the engine's performance. When it malfunctions, it can easily cause the engine temperature to become too high or even "boil over," or cause the warm-up time to be too long, leading to increased fuel consumption. Traditionally, thermostat housings are mostly made of die-cast aluminum. With the development of lightweight vehicles, nylon plastic is increasingly chosen as the main material for thermostats to meet the requirements of lightweighting. At the same time, the strength requirements for plastic thermostat housings are also increasing, to achieve the function of replacing aluminum housings.

[0003] Plastic thermostats with claw structures represent a new development trend, with the strength design of the claws being particularly critical. Traditional die-cast aluminum thermostat housings have high claw strength and are not at risk of breakage, but plastic thermostats with claw structures are relatively weak and prone to breakage, leading to thermostat failure. 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. It mainly provides a semi-enclosed hook structure for a plastic-shell thermostat, which solves the technical problem mentioned in the background that plastic thermostats with hook structures are relatively weak, prone to breakage, and thus cause thermostat failure.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a semi-enclosed hook structure for a plastic shell thermostat, including a thermostat shell, wherein a hand bracket and a thermostat spring are provided inside the thermostat shell.

[0006] The thermostat housing includes a hook, the inner wall of which has a semi-enclosed slot for mounting a support bracket, and the outer wall of which has reinforcing ribs.

[0007] More preferably, the thermostat housing includes a thermostat housing body, and the hook is integrally formed at the top port of the thermostat housing body.

[0008] More preferably, the hooks are symmetrically distributed about the vertical center line of the thermostat housing body, and the open sides of the semi-enclosed slots on the two hooks are arranged in opposite directions. By rotating the support bracket, the extended ends at both ends can enter the corresponding slots through the open sides of the two slots respectively.

[0009] More preferably, the inner wall of the slot is provided with a groove corresponding to the shape and position of the protrusions at both ends of the protrusion of the handpiece bracket. Through the cooperation of the protrusions and the groove, a stable assembly effect is ensured between the handpiece bracket and the slot.

[0010] More preferably, the reinforcing ribs are arranged in a ring array along the outer wall of the hook claw. By setting the reinforcing ribs, the structural strength and deformation resistance of the hook claw are improved.

[0011] More preferably, one end of the thermostat spring abuts against the support bracket, and the other end abuts against the inner bottom surface of the thermostat housing, wherein a positioning groove adapted to the shape of the end of the thermostat spring is provided.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The semi-enclosed hook claw structure of the plastic shell thermostat, through the hook claw, the slot and the reinforcing rib, the slot is a semi-enclosed structure. Compared with the traditional open hook claw slot structure, the semi-enclosed slot can increase the strength of the hook claw without affecting the assembly of the hand part bracket and the plastic shell thermostat. At the same time, the reinforcing rib on the outer wall of the hook claw can enhance the strength of the hook claw, thereby solving the problem that the hook claw made of plastic material is weak and prone to breakage.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0018] Please refer to the appendix carefully. Figure 1-3 A semi-enclosed hook structure for a plastic-cased thermostat includes a thermostat housing 1, and a pair of brackets 2 and a thermostat spring 3 are provided inside the thermostat housing 1.

[0019] One end of the thermostat spring 3 abuts against the support bracket 2, and the other end abuts against the inner bottom surface of the thermostat housing 1. A positioning groove adapted to the shape of the end of the thermostat spring 3 is provided inside. The thermostat spring 3 is positioned by the positioning groove to prevent the thermostat spring 3 from shifting during operation and to ensure the stability of the thermostat operation.

[0020] It should be noted that the handpiece bracket 2 and thermostat spring 3 in this utility model are the same handpiece bracket 2 and thermostat spring 3 commonly used in thermostats. Therefore, the structure, function and assembly method of the handpiece bracket 2 and thermostat spring 3 will not be described in detail here.

[0021] The thermostat housing 1 includes a hook 102. The inner wall of the hook 102 is provided with a semi-enclosed slot 103 for mounting the support bracket 2. The outer wall of the hook 102 is provided with a reinforcing rib 104.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the thermostat housing 1 includes a thermostat housing body 101, and a hook 102 is integrally formed at the top port of the thermostat housing body 101. Through the integrated structural design, the overall connection strength and structural stability are effectively improved, and the structural stability and reliability of the thermostat housing 1 are enhanced.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the hooks 102 are symmetrically distributed about the vertical center line of the thermostat housing body 101, and the open sides of the semi-enclosed slots 103 on the two hooks 102 are set in opposite directions. The open side of the slot 103 is designed with an arc transition (radius R1.0mm) to avoid stress concentration caused by right angles. By rotating the hand support 2, the extended ends at both ends can enter the corresponding slots 103 through the open sides of the two slots 103 respectively, forming a unique rotation assembly structure. This design allows the hand support 2 to be inserted into the slots 103 by rotation, simplifying the assembly process. At the same time, the symmetrical force mode can effectively distribute the working load and improve the working stability of the thermostat housing 1 under complex working conditions.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the inner wall of the slot 103 is provided with grooves that correspond to the shape and position of the protrusions at both ends of the extended end of the support bracket 2. Through the cooperation of the protrusions and grooves, a stable assembly effect is achieved between the support bracket 2 and the slot 103. This design not only ensures the stable assembly of the support bracket 2 and the slot 103 and prevents relative displacement, but also facilitates quick positioning and improves assembly efficiency and accuracy due to the concave-convex cooperation structure.

[0025] In this embodiment, as Figure 2 As shown, the reinforcing ribs 104 are arranged in a ring array along the outer wall of the hook 102. By setting the reinforcing ribs 104, the structural strength and deformation resistance of the hook 102 are improved, which can enhance the durability and reliability of the thermostat housing 1 and ensure the long-term stable operation of the thermostat.

[0026] The specific operating procedure of this utility is as follows: When assembling the support bracket 2 and the thermostat housing 1, firstly, move the support bracket 2 so that the extended ends of the support bracket 2 at both ends enter the gap between the two claws 102, and move the support bracket 2 to the same horizontal height as the slots 103 of the two claws 102 on the thermostat housing 1. Then, according to the orientation of the open side of the slots 103 on the two claws 102, rotate the support bracket 2 clockwise or counterclockwise so that the extended ends of the support bracket 2 at both ends enter the corresponding slots 103. Then, according to the position of the groove in the slot 103, align the protrusions of the extended ends of the support bracket 2 with the groove. Then, move the support bracket 2 upward so that the protrusions of the extended ends of the support bracket 2 at both ends are engaged in the groove in the slot 103, thus realizing the assembly of the support bracket 2 and the claws 102.

[0027] The semi-enclosed slot 103 on the handpiece bracket 2 can increase the strength of the hook 102. At the same time, the reinforcing rib 104 added to the outer wall of the hook 102 can solve the problem that the hook 102 made of plastic is weak and prone to breakage.

[0028] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
