Detailed implementation manners

[0034] The following will describe in detail the specific implementation manners of the present disclosure with reference to the drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0035] In the present disclosure, unless otherwise stated, the orientation terms such as "inside" and "outside" refer to "inside" and "outside" relative to the contour of the corresponding component itself. In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequence and importance. Furthermore, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only for explaining and illustrating the present disclosure, and should not be construed as a limitation of the present disclosure.

[0036] The following will describe the runner mating structure, the runner mating device and the runner device in the exemplary embodiments of the present disclosure with reference to the drawings, wherein the runner device involved in the present disclosure is any device having a runner for the medium to flow through, and the runner mating device refers to a device used in cooperation with the aforementioned runner device.

[0037] Reference Figures 1 to 4As shown in the figure, in the first aspect of the present disclosure, a runner mating structure is provided, which includes a first main body 1 and a second main body 2 that cooperate with each other. The first main body 1 is provided with a sealing portion 3 and a connecting portion 4; the second main body 2 is formed with a runner 5 for medium flow and a runner opening 6 that communicates the runner 5 with the outside. The first main body 1 is inserted into the runner opening 6 to cooperate with the runner 5 in the second main body 2; that is, the runner device may include the second main body 2, and the runner mating device may include the first main body 1. Among them, the runner opening 6 includes a sealing section 61 and a connecting section 62. The sealing section 61 is arranged close to the runner 5, and the connecting section 62 is arranged away from the runner 5. The sealing portion 3 of the first main body 1 is arranged close to the runner 5 for sealing cooperation with the sealing section 61, and the connecting portion 4 is arranged away from the runner 5 for connecting and cooperating with the connecting section 62.

[0038] Therefore, through the technical solution of the present disclosure, due to the connection relationship between the connecting section 62 and the connecting portion 4, debris and other foreign matters may be generated during both the establishment process and the maintenance process of the connection relationship. Especially when this connection relationship is a mechanical connection relationship, that is, there is a mechanical connection structure. For example, when the first main body 1 and the second main body 2 are cooperated by mechanical connection methods such as threads, ferrule, and flange, due to the mutual friction and collision between the two main bodies, the generation of such debris and foreign matters will be more aggravated. In this way, since the sealing portion 3 is arranged closer to the runner 5, these foreign matters can be blocked outside the runner 5, thereby avoiding the pollution of the flowing medium and improving the working stability of the runner device.

[0039] Among them, the process of establishing and maintaining the above-mentioned connection relationship may include the following situations: After the first main body 1 is cooperated with the second main body 2, since the sealing section 61 is arranged close to the runner 5 and the connecting section 62 is arranged away from the runner 5, during the process of establishing or maintaining the connection relationship between the connecting portion 4 on the first main body 1 and the connecting section 62, the debris and other foreign matters generated will be blocked by the sealing portion 3 connected to the sealing section 61 during the process of moving toward the runner 5 side. Thus, even if debris and other foreign matters are generated during the process of establishing or maintaining the connection relationship between the connecting portion 4 and the connecting section 62, they can only be located outside the runner 5, that is, the debris and other foreign matters cannot enter the runner 5 through the runner opening 6, avoiding the situation where the foreign matters pollute the runner 5 and affect the normal operation of the device or product.

[0040] Among them, the above-mentioned mechanical connection structure has various forms. For example, the connecting portion 4 and the connecting section 62 can be cooperated together by mechanical connection methods including but not limited to the above-mentioned thread connection, clamping, or connection by flange and screw, etc. Thus, the debris and other foreign matters generated due to the mutual friction and collision between the connecting portion 4 and the connecting section 62 during connection will be blocked by the sealing portion 3 close to the runner 5 when moving toward the runner 5 side and cannot enter the runner 5. Based on this, the normal use of the device or product is ensured, and its working stability is improved.

[0041] Specifically, as Figure 2 shown, the connecting portion 4 can be configured as an external thread 41, and the connecting section 62 can be configured as an internal thread. That is, the first main body 1 and the second main body 2 can be cooperatively connected by a threaded connection. The structure of the threaded connection is simple, and the first main body 1 and the second main body 2 can be connected together without complex parts or tools. In addition, during disassembly and assembly, only one of the first main body 1 and the second main body 2 needs to be rotated forward or backward, which improves the disassembly and assembly efficiency. After adopting the technical solution provided by the present disclosure, the debris generated during the threaded connection process and the use process will be blocked outside the flow channel 5.

[0042] Alternatively, in some unillustrated ways, the connecting portion 4 can be configured as one of a clamping block and a clamping groove that can be clamped and cooperated with each other, and the connecting section 62 can be the other of the clamping block and the clamping groove. That is, the first main body 1 and the second main body 2 can be connected together by a clamping connection. The foreign matters such as debris generated during the process of the clamping block being inserted into the clamping groove and during use will be blocked outside the flow channel 5 by the sealing portion 3, ensuring the normal operation of the product and the device.

[0043] Or, the connecting portion 4 can be configured as a first flange, and the connecting section 62 can be configured as a second flange formed on the outside of the flow port 6 and capable of cooperating with the first flange. Although the connection position of the first flange and the second flange is on the outside of the second main body 2, some of the debris and other sundries generated by their mutual collision and friction during connection may still fall into the flow port 6 and move toward the flow channel 5 side. However, since the sealing section 61 is arranged close to the flow channel 5 side, these sundries will be blocked by the sealing portion 3 that is pressed against the sealing section 61 before entering the flow channel 5, so as to ensure that foreign matters cannot enter the flow channel 5, ensuring the normal use of the device or product and improving its stability during operation.

[0044] In some embodiments, as Figure 2 shown, the sealing portion 3 can include a seal 32, and the sealing section 61 includes a sealing surface 611 that is pressed against the seal 32. When the sealing portion 3 is in sealing cooperation with the sealing section 61, the seal 32 can abut against the sealing surface 611, that is, the seal 32 will be squeezed by the sealing surface 611, so it can be closely attached to the sealing surface 611. Exemplarily, the seal 32 can be configured as a polymer elastic seal 32 made of a rubber material such as polyurethane. The polymer elastic seal 32 has good elasticity and temperature and pressure resistance. The polymer elastic member can be closely attached to the sealing surface 611 under the action of its elastic force. Thus, the sealing effect of the sealing section 61 is ensured, and the debris generated when the connecting portion 4 is connected to the connecting section 62 is prevented from entering the flow channel 5.

[0045] In addition, as Figure 2As shown, the sealing portion 3 may further include a sealing groove 31 formed on the outer peripheral wall of the first body 1, and the seal 32 is configured as a sealing ring 321 sleeved on the sealing groove 31. The setting of the sealing groove 31 can improve the disassembly and assembly efficiency of the sealing ring 321 while ensuring the stability of the sealing ring 321 after being connected to the first body 1.

[0046] In an embodiment of the present disclosure, as Figures 1 to 4 shown, the inner diameter of the connecting section 62 may be greater than the inner diameter of the sealing section 61, the outer diameter of the connecting portion 4 is greater than the outer diameter of the sealing portion 3, the outer diameter of the connecting portion 4 is greater than the outer diameter of the sealing section 61, and the inner diameter of the connecting section 62 is greater than the outer diameter of the sealing portion 3. In this way, when the first body 1 and the second body 2 are matched, the sealing portion 3 of the second body 2 will not contact the connecting section 62 during the process of passing through the connecting section 62 of the first body 1, thereby preventing, for example, the sealing ring 321 of the sealing portion 3 from being damaged by the connecting portion 4. Especially for the sealing ring 321 made of the above-mentioned polymer elastic material, it is avoided that the seal 32 is damaged due to contact friction with, for example, the internal thread on the connecting section 62, thereby affecting the sealing effect after the sealing portion 3 is connected to the sealing section 61. Of course, since the outer diameter of the connecting portion 4 is greater than the outer diameter of the sealing section 61, the sealing section 61 can also play a certain limiting role on the connecting portion 4, so that the connecting portion 4 cannot enter the sealing section 61, avoiding damage to the structure or components in the sealing section 61 caused by the connecting portion 4 extending into the sealing section 61.

[0047] Specifically, as Figures 1 to 4 shown, the inner diameter of the connecting section 62 may be 0.3-0.5 mm larger than the outer diameter of the sealing portion 3, which can not only ensure stable sealing but also avoid being scratched by the structure of the connecting section 62.

[0048] In some embodiments, as Figures 1 to 4 shown, along the insertion direction of the first body 1, the length of the sealing section 61 may not be less than the length of the connecting section 62, so that after the connection relationship between the connecting portion 4 and the connecting section 62 is established, the sealing portion 3 can be located in the sealing section 61. Exemplarily, the connecting portion 4 and the connecting section 62 may be connected in a threaded connection manner, and the sealing portion 3 and the sealing section 61 are sealed by the sealing ring 321 pressing against the sealing surface 611. If the sealing portion 3 is also located in the sealing section 61 when the external thread 41 and the internal thread are initially engaged, then during the process of screwing the internal and external threads together, the sealing portion 3 will also gradually move within the sealing section 61 until the internal and external threads are screwed together and the sealing portion 3 stops moving; since the length of the sealing section 61 is not less than the length of the connecting section 62, it can be ensured to a certain extent that the sealing portion 3 is still in the sealing section 61 after the above connection relationship is established, thereby ensuring the sealing effect.

[0049] In addition, the sealing section 61 and the connecting section 62 can be arranged adjacent to each other, and / or the sealing portion 3 and the connecting portion 4 can be arranged at intervals, and the interval between the two is not less than the length of the connecting section 62. Thus, the sealing portion 3 can enter the sealing section 61 at least when the connecting portion 4 is connected to the connecting section 62, and still be in the sealing section 61 after the connecting portion 4 and the connecting section 62 are connected, thereby ensuring the sealing effect after the first body 1 and the second body 2 are connected. In addition, if Figure 4 As shown, the sealing section 61 and the connecting section 62 may also be spaced apart, as long as the sealing portion 3 is located in the sealing section 61 when the connecting section 62 is connected to the connecting portion 4 and remains in the sealing section 61 after the connecting section 62 is connected to the connecting portion 4.

[0050] Among them, Figures 1 to 4 As shown, the length of the interval between the sealing portion 3 and the connecting portion 4 is 0.3-1 mm longer than the connecting section. For example, when the connecting section 62 and the connecting portion 4 are matched in a threaded connection, the arrangement of the present disclosure can ensure that when the connection relationship between the internal and external threads is initially established, the sealing portion 3 is already located in the sealing segment 61 to seal the flow channel 5. Even if foreign matter such as debris is generated during the screwing process of the internal and external threads, the sealing portion 3 will block these foreign matter outside the flow channel 5, that is, the sealing portion 3 of the first body 1 can first be sealed with the sealing segment 61 of the second body 2, and then the connecting portion 4 of the first body 1 is connected to the connecting segment 62 of the second body 2; or, while the sealing portion 3 of the first body 1 is sealed with the sealing segment 61 of the second body 2, the connecting portion 4 of the first body 1 is connected to the connecting segment 62 of the second body 2, that is, the sealing portion 3 will be connected to the flow channel opening 6 before the connecting portion 4, or, the sealing portion 3 and the connecting portion 4 are connected to the flow channel opening 6 at the same time, thereby ensuring the normal operation of the device or product and its stability during operation.

[0051] In the embodiments of the present disclosure, Figure 2 As shown, the first body 1 has a connecting cavity 7 connected to the flow channel opening 6, that is, as an embodiment, the first body 1 as a flow channel matching device is a flow channel switching device, which can make the medium in the flow channel 5, such as oil, flow out or flow in through the first body 1, thereby realizing the extension of the flow channel 5. In other possible embodiments, the first body 1 as a flow channel matching device can also be a flow channel blocking device such as a plug, thereby realizing the cutoff of the flow channel 5.

[0052] Specifically, the first body 1 may include a first connection end 101 and a second connection end 102 which are oppositely arranged. Among them, the first connection end 101 is used to be inserted into the fluid port 6, the sealing portion 3 is arranged close to the first connection end 101, the connecting portion 4 is arranged away from the first connection end 101, and the second connection end 102 can be communicated with the device for storing the medium, so that the medium can flow from the second connection end 102 to the first connection end 101 through the communication cavity 7, and then enter the flow channel 5.

[0053] The above technical solution of the present disclosure has been described in detail from the perspective of the overall structure of the flow channel cooperation. Next, it will be separately described from the perspectives of the flow channel device and the flow channel cooperation device. To avoid repetition, the repeated features and effects will be briefly described. Optionally, the flow channel 5 can be configured as an oil channel, that is, used for the flow of oil. In one embodiment, the oil channel device provided by the present disclosure is a damper forming the oil channel, and the oil channel cooperation device is the nozzle of the accumulator that needs to be connected to the damper. It should be noted that the application scenarios of the present disclosure are not limited to this, and various devices involving the flow channel 5 and the cooperation of the flow channel 5 are within the protection scope of the present disclosure.

[0054] In the second aspect of the present disclosure, as Figure 3 shown, a flow channel cooperation device is provided for cooperating with a flow channel device. The flow channel device is formed with a flow channel 5 and a fluid port 6 communicating the flow channel 5 with the outside. The fluid port 6 includes a sealing section 61 and a connecting section 62. The flow channel cooperation device includes a first body 1 for being inserted into the fluid port 6, and the first body 1 includes a sealing portion 3 and a connecting portion 4. The sealing portion 3 is arranged close to the flow channel 5 and is used for sealing cooperation with the sealing section 61, and the connecting portion 4 is arranged away from the flow channel 5 and is used for connecting with the connecting section 62. When the flow channel cooperation device and the flow channel device are cooperating, since the sealing portion 3 is arranged closer to the flow channel 5 than the connecting portion 4, the sealing portion 3 can block foreign matters such as debris generated during the establishment or maintenance of the connection relationship between the connecting portion 4 on the first body 1 and the connecting section 62. Thus, it is ensured that the debris cannot enter the flow channel 5 through the fluid port 6, ensuring the normal use of the flow channel device.

[0055] To facilitate the connection between the first body 1 and the flow channel cooperation device and ensure the stability after their connection, as Figure 3 shown, the connecting portion 4 can be configured as a mechanical connection structure to be connected with the fluid port 6. Specifically, the connecting portion 4 can be configured as an external thread 41, and the sealing portion 3 can include a sealing member 32 and a sealing groove 31 formed on the outer peripheral wall of the first body 1. Among them, the sealing member 32 can be configured as a sealing ring 321 sleeved on the sealing groove 31, which can facilitate the connection between the sealing member 32 and the first body 1 while ensuring the sealing effect of the sealing portion 3. In addition, to further improve the sealing effect, the sealing ring 321 can adopt a high molecular elastic sealing ring 321 with good elasticity and temperature and pressure resistance performance.

[0056] In an embodiment of the present disclosure, as Figures 1 to 4 shown, the inner diameter of the connecting section 62 can be greater than the inner diameter of the sealing section 61, the outer diameter of the connecting portion 4 can be greater than the outer diameter of the sealing portion 3, the outer diameter of the connecting portion 4 can be greater than the outer diameter of the sealing section 61, the inner diameter of the connecting section 62 can be greater than the outer diameter of the sealing portion 3 and the inner diameter of the connecting section 62 is 0.3 - 0.5 mm larger than the outer diameter of the sealing portion 3. The sealing portion 3 and the connecting portion 4 are arranged at intervals, and the interval between the two is not less than the length of the connecting section 62. The length of the interval between the sealing portion 3 and the connecting portion 4 is 0.3 - 1 mm longer than the connecting section 62. In this way, it can be ensured that when the sealing portion 3 enters the flow port 6, the sealing portion 3 will not be worn due to contact with the connecting section 62, and it can also be ensured that when the connecting portion 4 is connected and matched with the connecting section 62 or after the connection is completed, the sealing portion 3 is still in the sealing section 61 to ensure that it can achieve a good sealing effect and prevent foreign matters such as debris from entering the flow channel 5 through the flow port 6. In addition, since the outer diameter of the connecting portion 4 is greater than the outer diameter of the sealing section 61, the sealing section 61 can also play a certain limiting role on the connecting portion 4, so that the connecting portion 4 cannot enter the sealing section 61, avoiding damage to the structures or components in the sealing section 61 caused by the connecting portion 4 extending into the sealing section 61.

[0057] In some embodiments, as Figure 2 shown, the first main body 1 has a communication cavity 7 communicating with the flow port 6 inside. This can enable the medium storage device connected to the first main body 1, such as the oil in the accumulator that can supply oil to flow, to enter the flow channel 5 through the communication cavity 7, thereby ensuring the use of the flow channel device, such as a damper.

[0058] Exemplarily, as Figure 1 , Figure 2 and Figure 4 shown, the flow channel matching device can be the nozzle structure of the accumulator, that is, one end of the nozzle structure is connected to the flow channel device, and the other end is connected to the accumulator. The accumulator has a chamber for storing oil inside. After the nozzle structure is connected to the accumulator, the communication cavity 7 can be communicated with the chamber, so that the oil in the chamber can flow between the accumulator and the flow channel device. Of course, in other possible embodiments, the flow channel matching device can also be a flow channel blocking device such as a plug to achieve the cutoff of the flow channel 5.

[0059] In the third aspect of the present disclosure, as Figure 3As shown in the figure, a runner device is provided for cooperating with a runner mating device. The runner mating device includes a sealing portion 3 and a connecting portion 4. The runner device includes a second main body 2, and the second main body 2 is formed with a runner 5 for the flow of a medium and a runner opening 6 that communicates the runner 5 with the outside. The runner opening 6 includes a sealing section 61 and a connecting section 62. The sealing section 61 is arranged close to the runner 5 and is used for sealing cooperation with the sealing portion 3. The connecting section 62 is arranged away from the runner 5 and is used for connecting with the connecting portion 4. Since the sealing section 61 of the runner opening 6 is arranged on the side of the runner opening 6 close to the runner 5, during the connection process of the runner device and the runner mating device, the sealing section 61 of the runner opening 6 can be connected to the sealing portion 3 before the connecting section 62 is connected to the connecting portion 4 or at the same time when the connecting section 62 is connected to the connecting portion 4. Thus, even if debris is generated due to mutual friction between the connecting section 62 and the connecting portion 4 when they are connected, the sealing portion 3 can prevent the debris from entering the runner 5 through the runner opening 6. Based on this, the normal use of the runner device is ensured.

[0060] In an embodiment of the present disclosure, as Figure 3 shown, the connecting section 62 can be configured as a mechanical connection structure. For example, the connecting section 62 can be configured as an internal thread, and the sealing section 61 includes a sealing surface 611 that is in pressing fit with the sealing portion 3. The runner device and the runner mating device are connected by means of such a mechanical connection as a threaded connection, which can ensure the stability of the two after connection while keeping the structure relatively simple. The sealing surface 611 can be in contact with the sealing ring 321 of the sealing portion 3, thereby ensuring the sealing performance of the runner opening 6.

[0061] In some embodiments, as Figures 1 to 4 shown, the inner diameter of the connecting section 62 can be greater than the inner diameter of the sealing section 61; the outer diameter of the connecting portion 4 can be greater than the outer diameter of the sealing portion 3, the outer diameter of the connecting portion 4 can be greater than the outer diameter of the sealing section 61, the inner diameter of the connecting section 62 can be greater than the outer diameter of the sealing portion 3. The sealing section 61 and the connecting section 62 are arranged adjacent to each other, and the length of the sealing section 61 is not less than the length of the connecting section 62. Among them, the inner diameter of the connecting section 62 is 0.3 - 0.5 mm larger than the outer diameter of the sealing portion 3, and the length of the interval between the sealing portion 3 and the connecting portion 4 is 0.3 - 1 mm longer than the connecting section 62. On the one hand, this can ensure that the sealing portion 3 on the runner mating device will not be damaged due to contact with the connecting section 62 when passing through the connecting section 62. On the other hand, it can also ensure that after the connecting section 62 is cooperated with the sealing portion 3 on the runner mating device, the sealing portion 3 is still within the sealing section 61, thereby ensuring the sealing effect. In addition, since the outer diameter of the connecting portion 4 is greater than the outer diameter of the sealing section 61, the sealing section 61 can also play a certain limiting role on the connecting portion 4, so that the connecting portion 4 cannot enter the sealing section 61, avoiding damage to the structure or components in the sealing section 61 caused by the connecting portion 4 extending into the sealing section 61.

[0062] Exemplarily, the flow channel device of the present disclosure can be configured as a damper.

[0063] In a fourth aspect of the present disclosure, a vehicle is provided. The vehicle can be any suitable type of ground vehicle, such as a sedan, a van, a bus, etc. It includes the above-mentioned flow channel matching structure. The first body 1 is configured as a nozzle of an accumulator, and the second body 2 is configured as a damper. The damper can be connected to the suspension system of the vehicle to reduce the vibration of the vehicle during driving and improve comfort. The accumulator can provide hydraulic oil to the damper under appropriate circumstances to provide additional damping force to help the damper better absorb vibration. For example, when the vehicle is driving smoothly, the damper of the suspension system does not frequently compress and rebound. The oil pump in the vehicle hydraulic system can pump the oil into the accumulator for storage. When the vehicle passes through a bumpy road surface, the accumulator can supply energy by compressing gas to deliver the oil to the damper to provide additional hydraulic pressure to help the damper respond faster and improve the comfort of the vehicle during driving.

[0064] In addition, it should be noted that the vehicle has all the beneficial effects of the flow channel matching structure, and the present disclosure will not elaborate on them here.

[0065] In summary, the present disclosure exemplarily shows the working principle of the flow channel matching structure.

[0066] When the nozzle structure of the accumulator is connected to the flow channel of the damper, the first body 1 will be inserted into the flow port 6. At this time, since the sealing section 61 is close to the flow channel 5 side and the interval between the sealing part 3 and the connecting part 4 is not less than the length of the connecting section 62, the sealing ring 321 of the first body 1 will first abut and seal with the sealing surface 611. Subsequently, the external thread 41 on the first body 1 will be threadedly connected to the internal thread at the connecting part 4. Or, while the sealing ring 321 of the first body 1 abuts and seals with the sealing surface 611, the external thread 41 on the first body 1 is threadedly connected to the internal thread at the connecting part 4. Thus, the debris that falls to the flow port 6 due to mutual friction during threaded connection cannot enter the flow channel 5 through the flow port 6. Based on this, the normal use of the device or product is ensured, and its working stability is improved.

[0067] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0068] In addition, it should be noted that, for the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination manners.

[0069] In addition, any combination can be made among various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
