Description

Technical Field

[0001] This utility model relates to the field of coolant control water valve technology, and specifically to a coolant control water valve. Background Technology

[0002] In automotive thermal management systems, the coolant control valve consists of the valve body and the actuator that drives it, both of which need to be reliably installed and fixed. Currently, the industry commonly uses screw connections. Screws, as additional parts, not only increase material procurement and management costs but also require multiple assembly processes, such as aligning screw holes and tightening torque, thus affecting production efficiency.

[0003] Furthermore, vibrations and temperature fluctuations during vehicle operation can easily cause screws to loosen, leading to control failure. Using anti-loosening screws would increase the difficulty of disassembly during subsequent actuator maintenance or upgrades, and could even damage the actuator itself. In addition, snap-fit ​​connections are prone to brittleness or creep at high and low temperatures, and adhesive bonding methods are slow to cure and prone to aging. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to provide a coolant control valve that is simple to assemble, reduces manufacturing costs, and facilitates future replacement.

[0005] To achieve the above objectives, this utility model proposes a coolant control water valve, comprising: Water valve body and water valve actuator; The outer shell of the water valve body is integrally injection molded with multiple stepped columns. Each stepped column has a threaded hole. The outer shell of the water valve actuator has a through hole that matches the stepped column. The stepped column is inserted into the through hole, and the free end of the stepped column extends out of the through hole. The part of the stepped column extending out of the through hole is riveted to form a cap, so that the outer shell of the water valve body and the outer shell of the water valve actuator are fixedly connected.

[0006] According to the present invention, a coolant control water valve is provided. A stepped column with a threaded hole is integrally injection molded on the outer shell of the water valve body. The water valve actuator has a matching through hole. After the stepped column is inserted into the through hole, it can be fixed by hot riveting to form a cap. No additional screws are required, reducing parts and assembly steps and simplifying assembly. It saves on screw procurement and assembly costs and reduces manufacturing costs. When the actuator needs to be replaced later, after removing the cap, the new actuator can be fixed with screws through the threaded hole of the stepped column, achieving convenient replacement.

[0007] In addition, the coolant control water valve proposed in the above embodiments of this utility model may also have the following additional technical features: Optionally, the stepped column is further provided with a light hole, which is a frustum-shaped structure with a larger upper part and a smaller lower part. The light hole is connected to the threaded hole and is located above the threaded hole.

Detailed Implementation

[0012] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0013] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0014] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0015] The following is for reference. Figures 1-5 The implementation of the coolant control valve proposed in the embodiments of this utility model will be described in detail.

[0016] According to an embodiment of the present invention, a coolant control water valve includes: a water valve body 1 and a water valve actuator 2; The outer shell of the water valve body 1 is integrally injection molded with multiple stepped columns 11. The stepped columns 11 are provided with threaded holes 111. The outer shell of the water valve actuator 2 is provided with through holes 21 that are adapted to the stepped columns 11. The stepped columns 11 are inserted into the through holes 21, and the free end of the stepped columns 11 extends out of the through holes 21. The part of the stepped columns 11 extending out of the through holes 21 is formed into a cap 112 by hot riveting, so that the outer shell of the water valve body 1 and the outer shell of the water valve actuator 2 are fixedly connected.

[0017] In other words, the coolant control water valve mainly consists of two parts: the valve body 1 and the actuator 2. The actuator 2 provides the power for the rotation of the valve core of the valve body 1. The outer shell of the valve body 1 is integrally injection molded, forming multiple stepped columns 11, each with a pre-drilled threaded hole 111. This integral molding method eliminates the need for subsequent processing and fixing of the structure, while also ensuring the connection strength between the stepped columns 11 and the outer shell. The outer shell of the actuator 2 has through holes 21 corresponding to the size and position of the stepped columns 11. During assembly, simply align the stepped columns 11 of the valve body 1 and insert them into the through holes 21 of the actuator 2. After the free end of the stepped column 11 extends out of the through hole 21, the extended portion is then secured using a hot riveting process. The thermoforming process forms a cap 112 covering the through hole 21. This cap 112 fits tightly against the housing of the water valve actuator 2, fixing the housing of the water valve actuator 2 between the cap 112 and the stepped surface of the stepped post 11. This firmly secures the water valve body 1 and the water valve actuator 2. The entire assembly process requires no additional screws, simplifying operation and ensuring connection stability. Simultaneously, the threaded hole 111 within the stepped post 11 provides space for future structural expansion. When the water valve actuator 2 needs upgrading or repair / replacement, the cap 112 can be removed, and screws can be used for fixation. This ensures both efficient assembly during production and convenient replacement later. The water valve body 1 and the water valve actuator 2 can utilize existing structures. Both the housing of the water valve body 1 and the water valve actuator 2 can be made of PA66+GF30 engineering plastic. The number of stepped posts 11 can be set according to actual needs.

[0018] Therefore, the coolant control water valve is fixed by integrally injection molding a stepped post 11 with a threaded hole 111 on the outer shell of the water valve body 1. The water valve actuator 2 is provided with a matching through hole 21. After the stepped post 11 is inserted into the through hole 21, a cap 112 is formed by hot riveting. No additional screws are required, reducing parts and assembly steps and simplifying assembly. It saves on screw procurement and assembly costs and reduces manufacturing costs. When the actuator needs to be replaced later, after removing the cap 112, the new actuator can be fixed with screws through the threaded hole 111 of the stepped post 11, achieving convenient replacement.

[0019] Optionally, the stepped column 11 is also provided with a clear hole 113. The clear hole 113 is a frustum-shaped hole, wider at the top and narrower at the bottom. The clear hole 113 connects to the threaded hole 111 and is located above the threaded hole 111. Understandably, the clear hole 113 is located near the free end of the stepped column 11, and the threaded hole 111 is located at the bottom of the clear hole 113. The diameter of the clear hole 113 near the free end is larger than the diameter away from the free end. This ensures that the portion of the stepped column 11 extending out of the through hole 21 will not block the threaded hole 111 during the hot riveting softening process, guaranteeing normal operation of the threaded hole 111 when replacing the water valve body 1 or the water valve actuator 2. Alternatively, an insert can be inserted into the clear hole 113 before hot riveting to prevent blocking the threaded hole 111. The insert can be placed on the hot riveting head of the hot riveting equipment. The length of the portion of the stepped column 11 extending out of the through hole 21 can be 5mm-10mm, and the thickness of the cap 112 can be 3mm-5mm.

[0020] Optionally, the number of stepped pillars 11 is 3-4, and they are distributed circumferentially along the outer shell of the water valve body 1. Understandably, setting 3-4 stepped pillars 11 is based on a balance between structural stability and processing cost, which simplifies the injection mold structure of the water valve body 1, reduces molding difficulty, is suitable for coolant control scenarios with tight installation space, and simultaneously meets the basic connection strength requirements. Preferably, there are 3 stepped pillars 11.

[0021] Optionally, the outer wall of the end of the stepped column 11 is provided with a chamfer 114. Understandably, during assembly, the chamfer 114 can play a guiding role, so that even if there is a slight coaxiality deviation between the through hole 21 of the water valve actuator 2 and the stepped column 11, it can guide the stepped column 11 to be smoothly inserted into the through hole 21, avoiding the outer wall of the stepped column 11 from scratching the inner wall of the through hole 21 due to hard insertion, or prolonging the assembly time due to jamming.

[0022] Optionally, the brim 112 is mushroom-shaped. Understandably, since the stepped post 11 has a threaded hole 111, the width and thickness of the brim 112 formed by hot riveting are not as good as those of a solid post. By setting the brim 112 into a mushroom shape, the local thickness near the threaded hole 111 is thicker after hot riveting, and the local thickness away from the threaded hole 111 is thinner. This makes up for the insufficient strength caused by the threaded hole 111. It can not only save the material of the stepped post 11 and reduce the length of the part of the stepped post 11 extending out of the through hole 21, but also ensure the connection strength.
