Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an automotive coolant reservoir. Background Technology

[0002] In the automotive manufacturing industry, with continuous technological advancements and innovations, every component of a car is constantly evolving and improving. As a key component of the automotive cooling system, the coolant reservoir plays a crucial role in the normal operation of the vehicle. The coolant reservoir stores coolant, providing a continuous cooling medium for the engine during operation, ensuring the engine runs at a suitable temperature, preventing engine damage due to overheating, and thus improving the overall performance and lifespan of the vehicle.

[0003] In existing technologies, to meet the needs of adding and storing automotive coolant, conventional automotive coolant reservoirs typically employ a simple upper and lower shell assembly. For adding coolant, a filler tube is usually located in the upper shell, equipped with a standard cap. When coolant needs to be added, the operator simply opens the cap and pours the coolant into the reservoir through the filler tube. Regarding closure, most systems rely on a simple seal from the cap, lacking a dedicated closing mechanism. Furthermore, there is no dedicated drive mechanism to precisely control the coolant injection process. Some coolant reservoirs may only roughly control the flow by opening and closing the cap, failing to effectively regulate the coolant injection process.

[0004] However, these conventional methods in the existing technology have obvious drawbacks. Ordinary plug-cap sealing methods are difficult to guarantee the airtightness of the coolant reservoir, which can easily lead to coolant leakage and thus affect the engine's cooling performance.

[0037] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0038] This application discloses an automotive coolant reservoir.

[0039] Example 1: Reference Figure 1 As shown, an automotive coolant reservoir includes an upper housing 1, a lower housing 2, a filler tube 11, a stopper cap 14, a closing mechanism 111, and a drive mechanism 112. The upper housing 1 and the lower housing 2 together form the main body of the coolant reservoir. The filler tube 11 is mounted on the upper housing 1 for adding coolant. The stopper cap 14 is arranged on the filler tube 11 to provide a preliminary seal. The closing mechanism 111 is arranged inside the filler tube 11 for precisely controlling the coolant injection. The drive mechanism 112 is arranged on the upper housing 1 to control the opening and closing of the closing mechanism 111. This arrangement improves the internal sealing of the coolant reservoir and precisely controls the coolant addition process. At the same time, the drive mechanism 112 can accurately control the opening and closing of the closing mechanism 111 to avoid coolant leakage.

[0040] Reference Figure 2 As shown, the closing mechanism 111 includes a closing fixed seat 1111, a movable plate 1112, and a baffle 1113. The closing fixed seat 1111 is arranged inside the upper housing 1, providing a base for the installation and movement of the movable plate 1112 and the baffle 1113. A first pin 11111 is arranged on the closing fixed seat 1111, and a first movable groove 11121 is arranged on the movable plate 1112 for the first pin 11111 to move in. The first movable groove 11121 is an arc-shaped groove arranged on the movable plate 1112, and the first pin 11111 is adapted to the first movable groove 11121, allowing the first pin 11111 to slide within the first movable groove 11121. The closing fixed seat 1111 is fixed to the upper housing 1, and the movable plate 1112 is limited by the first pin 11111, thereby enabling it to move within the closing fixed seat 1111. The range of movement is the length range of the first movable groove 11121.

[0041] A second pin 11131 is provided on the baffle 1113. The second pin 11131 is a cylindrical rod and has the same design as the first pin 11111. A second movable groove 11124 is also provided on the movable plate 1112, within which the second pin 11131 moves. A hinge shaft 11132 is arranged on the baffle 1113 and is hinged to the closed fixed seat 1111. One end of the baffle 1113 can rotate on the closed fixed seat 1111. The baffle 1113 has several pieces, for example, 3-5 pieces. In this embodiment, 5 pieces are provided. The baffles 1113 mesh together to form a circle that blocks the coolant inlet pipe 11, effectively preventing the flow of coolant when closed. The movable plate 1112 has a first side 11122 on its side, and a first rack 11123 is provided on the first side 11122. The first rack 11123 can be a toothed structure formed on the side of the movable plate 1112 by mechanical processing. Its function is to cooperate with the drive mechanism 112 to realize the movement of the movable plate 1112.

[0042] Reference Figure 3 As shown, the drive mechanism 112 includes a movable seat 1121 arranged on the side wall of the liquid filling pipe 11 and a rotating assembly 1122 arranged on the side of the movable seat 1121. The movable seat 1121 is arranged on the liquid filling pipe 11, and the upper housing 1 is provided with a third pin 11214. The movable seat 1121 is provided with a third movable groove 11211 for the third pin 11214 to move. The third pin 11214 is a cylindrical rod, and the third movable groove 11211 is an arc-shaped groove. The third pin 11214 is fixed above the upper housing 1. The movable seat 1121 is sleeved on the liquid filling pipe 11 and is arranged concentrically with the liquid filling pipe 11. The movable seat 1121 rotates on the liquid filling pipe 11, and the range of motion of the movable seat 1121 is the length range of the third movable groove 11211. The dimensions and shape of the third movable groove 11211 are adapted to the third pin 11214, allowing the third pin 11214 to move within the third movable groove 11211. A limiting hole 11215, which is a circular through hole, is provided on the movable seat 1121. The movable seat 1121 can be made of metal or plastic, and its shape is designed according to the structure and working requirements of the liquid filling pipe 11.

[0043] The rotating assembly 1122 includes a second side 11212 arranged on the movable seat 1121, a second rack 11213 arranged on the second side 11212, a second conical plate 11223 meshing on the second rack 11213, a connecting shaft 11222 arranged on the second conical plate 11223, and a first conical plate 11221 arranged on the connecting shaft 11222 and meshing with the first rack 11223. The second side 11212 is a side structure on the movable seat 1121, and the second rack 11213 is disposed on the second side 11212, its toothed structure meshing with the teeth on the second conical plate 11223. The second conical plate 11223 and the first conical plate 11221 are generally conical gear structures. The connecting shaft 11222 connects the second conical plate 11223 and the first conical plate 11221, enabling them to rotate coaxially. The connecting shaft 11222 can be a cylindrical metal rod, with its two ends fixed to the second conical plate 11223 and the first conical plate 11221 respectively via key connections. A knob 11224 is provided on the connecting shaft 11222. The knob 11224 is a circular handle, which allows the operator to manually rotate the connecting shaft 11222, thereby driving the first conical plate 11221 and the second conical plate 11223 to rotate. In turn, the first rack 11123 and the second rack 11213 control the movement of the movable plate 1112 and the movable seat 1121 respectively.

[0044] Reference Figure 4 As shown, the outer ring of the filling pipe 11 is provided with external threads, and a spiral slide 13 is arranged inside the filling pipe 11. The spiral slide 13 is made of plastic and is spiral in shape. It is arranged above the baffle 1113. When coolant is injected through the filling pipe 11, the spiral slide 13 can make the coolant flow along the spiral trajectory, which plays a role in buffering and dispersing the coolant and preventing the coolant from directly impacting the baffle 1113. At the same time, the spiral slide 13 has a hole in the middle for air exchange.

[0045] A locking assembly 12 is arranged on the side wall of the liquid filling tube 11. The locking assembly 12 includes a fixing ring 121 arranged on the side wall of the liquid filling tube 11, a movable rod 122 arranged on the fixing ring 121, and a limiting spring 123 installed on the circumference of the movable rod 122. The limiting spring 123 abuts against the end of the movable rod 122 and the fixing ring 121, and the movable rod 122 can be inserted into the limiting hole 11215.

[0046] When adding liquid, unscrew the cap 14 on the liquid adding tube 11. As the cap 14 is loosened, the movable rod 122 pressed under the cap 14 springs back under the action of the limiting spring 123, thereby disengaging the movable rod 122 from the limiting hole 11215. At this time, turn the knob 11224 to rotate the second conical plate 11223 and the first conical plate 11221, thereby rotating the movable plate 1112. The movable plate 1112 rotates within the limited range of the first movable groove 11121. During the rotation of the movable plate 1112, the second movable groove 11124 drives the second pin 11131 to move. The movement of the second pin 11131 causes the baffle 1113 to rotate within the closed fixed seat 1111. One end of the baffle 1113 is hinged within the closed fixed seat 1111. The movement of the second pin 11131 at one end causes the baffle 1113 to rotate around this hinge shaft 11132, thereby opening the meshing baffle 1113 and opening the liquid inlet. The user can then add coolant. The added coolant flows into the coolant reservoir through the spiral slide 13. After adding the coolant, turn the knob 11224 to rotate the movable plate 1112, thereby rotating the baffle 1113 to close the liquid inlet pipe 11. Tighten the cap 14 onto the liquid inlet pipe 11. As the cap 14 is tightened, it contacts the movable rod 122. Tightening the cap 14 also pushes the movable rod 122 downwards, inserting it into the limiting hole 11215 on the movable seat 1121, thus locking the movable seat 1121. When the limiting hole 11215 and the movable rod 122 are aligned vertically, the baffle 1113 engages, closing the filling tube 11. If the cap 14 is not tightened by turning the knob 11224, the movable rod 122 cannot be inserted into the limiting hole 11215 because the limiting hole 11215 and the movable rod 122 are misaligned, preventing further tightening of the cap 14 and alerting the user. To further enhance the sealing effect, a sealing plug is provided at the contact point between the cap 14 and the filling tube 11, improving the sealing performance.

[0047] The implementation principle of an automotive coolant reservoir according to an embodiment of this application is as follows: The automotive coolant reservoir is equipped with a closing mechanism 111 and a driving mechanism 112. The baffle 1113 in the closing mechanism 111, through the cooperation of the movable plate 1112 with the first pin 11111, the second pin 11131, and the hinge shaft 11132, can precisely control the opening and closing of the baffle 1113. The driving mechanism 112, through the cooperation of the knob 11224, the first conical plate 11221, and the second conical plate 11223, can accurately control the opening and closing of the closing mechanism 111, achieving precise control of the coolant adding process. Simultaneously, the spiral slide 13 can buffer the injection of coolant and prevent coolant splashing.

[0048] Example 2: Reference Figure 1 and Figure 6 As shown, the mounting bracket 3 is located on the side of the car coolant reservoir, that is, on one side of the upper housing 1 and the lower housing 2. The quick-release mechanism 31 is located on the mounting bracket 3, and the coolant reservoir can be quickly installed and removed through the quick-release mechanism 31, which improves the convenience of coolant reservoir installation and maintenance.

[0049] Reference Figure 7 As shown, the quick-release mechanism 31 includes a fixed post 311 fixed to the side of the upper housing 1 and a limiting component 312 arranged on the fixing frame 3. The limiting component 312 includes a limiting housing 3121 arranged on the fixing frame 3 and a movable ring 3122 slidably arranged in the axial direction of the limiting housing 3121; the limiting housing 3121 has an inner cavity 31211 for accommodating the fixed post 311, and the inner cavity 31211 is also provided with a first cavity 31212, in which a retractable first piston 31213 is arranged, and the movable ring 3122 can move up and down on the outside of the limiting housing 3121.

[0050] Reference Figure 7 As shown, the limiting housing 3121 has several first through holes 31214 circumferentially formed. Ball heads 31215 are arranged within the first through holes 31214. The ball heads 31215 are made of metal and have a smooth surface. The diameter of the first through holes 31214 within the first cavity 31212 is smaller than the diameter of the ball heads 31215, so part of the ball heads 31215 protrudes into the first cavity 31212 but cannot pass through. The limiting housing 3121 is provided with a first limiting platform 31216, and a first boss 31221 is provided within the movable ring 3122. A gap is left between the first boss 31221 and the first limiting platform 31216, and a first spring 31217 is provided between the first boss 31221 and the first limiting platform 31216. The first spring 31217 is fixedly connected to the first boss 31221 and the first limiting platform 31216. The first spring 31217 is selected with a spring coefficient corresponding to actual needs to ensure that the movable ring 3122 can cooperate with the limiting housing 3121 under normal conditions. When the movable ring 3122 slides, the first spring 31217 undergoes elastic deformation, providing a restoring force. Under normal conditions, under the action of the first spring 31217, the first boss 31221 is arranged outside the first through hole 31214. At the same time, the diameter of the first through hole 31214 is smaller than the diameter of the ball head 31215. The first boss 31221 will abut against the ball head 31215, so that the ball head 31215 is tightly attached to the first through hole 31214. The ball head 31215 protrudes into the first cavity 31212, reducing the movable diameter range within the first cavity 31212. The opening of the first through hole 31214 outside the limiting housing 3121 is larger than the diameter of the ball head 31215, thus allowing the ball head 31215 to move.

[0051] Reference Figure 7 and Figure 8 As shown, the first piston 31213 includes a first fixed seat 312131 disposed within the limiting housing 3121, a first piston rod 312132 disposed within the first fixed seat 312131, and a first compression spring 312133 disposed between the first piston rod 312132 and the first fixed seat 312131. The end face of the first piston rod 312132 is provided with a first inclined surface, and the opening of the first cavity 31212 is provided with a first guide surface that mates with the end face of the first piston rod 312132. A first sealing gasket is provided on the first piston rod 312132. The first fixed seat 312131 is fixedly disposed within the first cavity 31212, and the first fixed seat 312131 is provided with a first circular plate. The first circular plate is fixedly connected to the cavity wall of the first cavity 31212, and a circular hole for the first piston rod 312132 to move is opened at the center of the first circular plate. The first compression spring 312133 is selected with a spring coefficient corresponding to the actual situation to provide suitable elastic force. The design of the first inclined surface and the first guide surface limits the range of motion of the first piston rod 312132.

[0052] Reference Figure 7 and Figure 9 As shown, the fixed column 311 has a second cavity 3111, and a retractable second piston 3112 is arranged inside the second cavity 3111. The second piston 3112 includes a second fixed seat 31121 arranged inside the second cavity 3111, a second piston rod 31122 arranged inside the second fixed seat 31121, and a second compression spring 31123 arranged between the second piston rod 31122 and the second fixed seat 31121. The end face of the second piston rod 31122 is provided with a second inclined surface, the opening of the second cavity 3111 is provided with a second guide surface that mates with the end face of the second piston rod 31122, and a second sealing gasket is provided on the second piston rod 31122. The design structure of the second piston 3112 is the same as that of the first piston 31213, and will not be described in detail further.

[0053] The fixing post 311 is circumferentially provided with a snap-fit ​​groove 3113. The snap-fit ​​groove 3113 is an annular groove arranged on the side of the fixing post 311 and is used to cooperate with the limiting component 312 to achieve snap-fit. After the fixing post 311 is fully inserted into the inner cavity 31211, the snap-fit ​​groove 3113 corresponds to the first through hole 31214, and the ball head 31215 protruding from the first through hole 31214 can be snapped into the snap-fit ​​groove 3113.

[0054] Reference Figure 9As shown, the mounting bracket 3 has a vertically downward-pointing vertical rod 32 and a horizontal horizontal rod 33. The lower housing 2 abuts against the horizontal rod 33, and shock-absorbing pads are arranged on the horizontal rod 33 for vibration damping. The vertical rod 32 and horizontal rod 33 are generally made of metal, such as steel, to ensure the structural strength of the mounting bracket 3. The shock-absorbing pads can be made of rubber, which can effectively reduce the impact of vibrations generated during vehicle operation on the coolant reservoir. Alternatively, the shock-absorbing pads can also be made of silicone to provide better vibration damping.

[0055] The mounting bracket 3 has two sets, and a connecting rod 34 is fixedly installed between the two sets of movable rings 3122. A pressure rod 35 is installed on the connecting rod 34. The connecting rod 34 and the pressure rod 35 are made of metal. By pressing the pressure rod 35 to operate the connecting rod 34, the sliding of the movable rings 3122 on both sides can be controlled simultaneously, which facilitates the quick installation and removal of the coolant reservoir.

[0056] The implementation principle of an automotive coolant reservoir according to an embodiment of this application is as follows: A mounting bracket 3 is provided with bolt holes, and the mounting bracket 3 is installed on the vehicle frame using bolts. When installing the coolant reservoir, the fixing post 311 is aligned with the limiting component 312 and inserted; and during insertion, the pressing rod 35 is pressed down to depress the movable rings 3122 on both sides. The first boss 31221 inside the movable ring 3122 is pressed down, thereby compressing the first spring 31217. The first boss 31221 is further away from the first through hole 31214, increasing the activity space of the ball head 31215. Without the restriction of the first boss 31221, the ball head 31215 can contact the side of the movable ring 3122, increasing the range of motion of the ball head 31215. After the fixing post 311 is inserted into the limiting housing 3121, the first piston rod 312132 and the second piston rod 31122 abut against each other and compress each other. The end face of the fixing post 311 abuts against the end face of the inner cavity 31211 of the limiting housing 3121, thus achieving complete insertion. At this time, the pressure rod 35 is released, and the movable ring 3122 is not affected by external force. The compressed first spring 31217 generates elastic force to lift the movable ring 3122, and the lifted movable ring 3122 moves the ball head 31215 into the inner cavity 31211. The ball head 31215 protruding on the inner cavity 31211 engages with the locking groove 3113 on the fixing post 311. The first boss 31221 on the movable ring 3122 acts as a limit to prevent the ball head 31215 from loosening. The mutual limiting of the ball head 31215 and the locking groove 3113 allows the fixing post 311 to be engaged in the limiting housing 3121. When replacing the coolant reservoir, the user only needs to press the lever 35 to open the movable ring 3122. The first compression spring 312133 and the second compression spring 31123 return to their original deformation, lifting the fixing post 311 a certain distance. At the same time, the ball head 31215 in the first through hole 31214 is no longer limited by the first boss 31221 and moves freely. The ball head 31215 is no longer engaged with the locking groove 3113, making it easy for the user to remove the entire coolant reservoir. The quick-release mechanism 31 avoids the defects of traditional bolt connections, welding, and snap-fit ​​connections, improving the convenience of coolant reservoir installation and maintenance while ensuring the stability of the coolant reservoir.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
