[0001] The present application relates to the field of vehicle technology, and in particular to a joint device and a vehicle. Background Art

[0002] Corresponding pipes are generally required to be arranged in the vehicle's fuel system, cooling system and other systems. These pipes are connected to the cylinder or pump body in each system through a joint device to serve as a delivery channel for fluid media such as fuel and coolant.

[0003] In the related art, the joint device generally includes a plug and a joint. One end of the joint is pre-installed on the cylinder or pump body in each system, and the other end of the joint has a socket. One end of the plug is inserted into the socket, and the other end of the plug is connected to the pipeline. The joint and the plug are fixed by a clamping ring, so that the pipeline is connected to the cylinder or pump body in each system through the joint device.

[0004] However, in the related art, the snap ring may be located in some narrow spaces in the vehicle, which makes it difficult to remove the snap ring. Summary of the invention

[0005] The embodiments of the present application provide a connector device and a vehicle, wherein the retaining ring of the connector device can be rotated relative to the connector member and the plug member to a direction that is easily operated by fingers, thereby facilitating the disassembly of the connector device by fingers.

[0006] The embodiment of the present application provides a connector device, including a connector member, a plug member and a connection assembly;

[0007] One end of the connector is a socket end, and the socket end has an insertion port; one end of the plug member is a plug end, and the plug end is inserted into the insertion port;

[0008] The outer side wall of the connector has a first flange; the outer side wall of the plug has a second flange and a third flange, and a slot is formed between the second flange and the third flange;

[0009] The connection assembly comprises a connection ring and a snap ring, wherein the connection ring is sleeved on the outside of the connector and the plug, and the snap ring is sleeved on the outside of the connection ring;

[0010] The inner side wall of the connecting ring has a first latching tooth, and the first latching tooth is latched in the latching groove; the outer side wall of the connecting ring has a protruding portion, and the first latching tooth and the protruding portion are located at two ends of the connecting ring opposite to each other;

[0011] The inner side wall of the clamping ring is provided with a second clamping tooth, and the second clamping tooth is clamped with the first flange; the clamping ring has a notch at one end facing the connector, and the protrusion is clamped into the notch.

[0012] The connector device provided in the embodiment of the present application has a snap ring that can rotate relative to the plug member and the connector member. Even if the snap ring is located in some narrow spaces in the vehicle, when removing the snap ring, the snap ring can be rotated to a direction that is easy for fingers to operate, so that the snap ring can be removed with fingers.

[0013] In a possible implementation, in the connector device provided in the embodiment of the present application, the end of the connecting ring facing the connector member has a relief opening, and the second latching tooth passes through the relief opening and is latched with the first flange.

[0014] The avoidance opening is used for the second latching tooth to pass through and engage with the first flange. In this way, the second latching tooth does not need to fully extend to the lower end of the connecting ring, and then bypass the connecting ring to engage with the first flange, making the second latching tooth structure simpler and the connection more convenient. It also makes the structure between the clamping ring and the connecting ring more compact and does not occupy too much space.

[0015] In a possible implementation manner, in the connector device provided in the embodiment of the present application, the number of the protrusions is at least two, and at least two of the protrusions are spaced apart and distributed along the circumference of the connecting ring;

[0016] The number of the notches is at least two, and the positions of at least two of the notches correspond to the positions of at least two of the protrusions.

[0017] Multiple protrusions are inserted into the notches of the clamping ring, which can make the force between the clamping ring and the connecting ring more uniform and prevent a single protrusion from breaking due to excessive force.

[0018] In a possible implementation, in the connector device provided in the embodiment of the present application, there are multiple first latching teeth, and the multiple first latching teeth are evenly distributed along the circumference of the inner side wall of the connecting ring.

[0019] The first latching teeth are evenly distributed along the circumference of the inner side wall of the connecting ring, so that each first latching tooth can be stably inserted into the latching groove, and can ensure that each first latching tooth is evenly stressed, thereby avoiding breakage of a single first latching tooth due to excessive stress, and ensuring a stable connection between the connecting ring and the plug component.

[0020] In a possible implementation manner, in the connector device provided in the embodiment of the present application, the clamping ring includes an elastic plate, the elastic plate is curved in an arc shape, and an opening is formed between two ends of the elastic plate;

[0021] The second latching tooth is located on the inner side wall of the elastic plate, and the elastic plate has the notch at one end facing the connector.

[0022] When the snap ring is removed, an outward pulling force is applied to both ends of the elastic plate to enlarge the opening between the two ends of the elastic plate until the second locking tooth no longer engages the first flange, thereby separating the connector from the snap ring, and then separating the snap ring from the connecting ring, so that the snap ring can be easily removed.

[0023] In a possible implementation manner, in the connector device provided in the embodiment of the present application, the two ends of the elastic plate respectively have a first toggle portion and a second toggle portion;

[0024] The first shifting portion includes a first shifting rod, and the first shifting rod extends from the first end of the elastic plate toward the outside of the opening;

[0025] The second shifting portion includes a second shifting rod, and the second shifting rod extends from the second end of the elastic plate toward the outside of the opening;

[0026] The first and second toggle parts can be used as fulcrums. Compared with holding both ends of the elastic plate and applying force to expand the opening between the two ends of the elastic plate, pinching the first and second toggle parts can more conveniently expand the opening between the two ends of the elastic plate.

[0027] The first lever extends outward from the first end of the elastic plate toward the opening, which is equivalent to extending the first end of the elastic plate. Similarly, the second lever extends outward from the second end of the elastic plate toward the opening, which is equivalent to extending the second end of the elastic plate. When the snap ring needs to be removed, just hold the first lever and the second lever and apply force to expand the opening between the two ends of the elastic plate. This makes the removal of the snap ring more convenient and labor-saving.

[0028] In a possible implementation, in the connector device provided in the embodiment of the present application, the first lever is located on the side of the second lever facing the connector member, and a side of the protrusion facing the plug member abuts against a side of the first lever facing the connector member.

[0029] In a possible implementation, in the joint device provided in an embodiment of the present application, a center line of the elastic plate is colinear with a center line of the connecting ring.

[0030] In a possible implementation manner, in the connector device provided in the embodiment of the present application, the outer side wall of the plug member has an annular groove, and the annular groove is located on the outer side wall of the portion of the plug member inserted into the connector member;

[0031] A sealing ring is arranged in the annular groove, and the sealing ring abuts against the outer side wall of the plug component and the inner side wall of the connector component.

[0032] The embodiment of the present application also provides a vehicle, including the above-mentioned joint device. The pipelines in the fuel system, cooling system and other systems of the vehicle are connected to the cylinder or pump body in each system through the above-mentioned joint device. When it is necessary to disconnect the pipeline in the vehicle from the cylinder or pump body in the vehicle, even if the clamping ring 32 is located in some small space in the vehicle, the clamping ring 32 can be rotated to a position that is easy to observe and easy to operate with fingers, so that the clamping ring 32 can be easily disassembled with fingers, so that the pipeline in the vehicle is disconnected from the cylinder or pump body in the vehicle.

[0061] In the related art, the snap ring may be located in some small spaces in the vehicle, and it is difficult for fingers to reach into these small spaces when removing the snap ring. In addition, when turning on the switch of the snap ring, the position of the switch is not easy to observe due to the small space, and it is not convenient for fingers to operate in the small space, resulting in difficulty in removing the snap ring.

[0062] In view of this, the embodiment of the present application provides a connector device and a vehicle, wherein the connector device connects the connector member and the plug member through a connecting ring and a snap ring, and the snap ring can rotate relative to the connector member and the plug member. Even if the snap ring is located in some narrow spaces in the vehicle, the snap ring can be rotated to a position that is easy to observe and easy to operate with fingers, so that the snap ring can be easily removed with fingers.

[0063] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of them. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0065] See also Figure 1-Figure 5 As shown, an embodiment of the present application provides a connector device, including a connector member 10 , a plug member 20 and a connecting assembly 30 .

[0066] The connector 10 is used to be connected to a cylinder or pump body in a vehicle and serves as an input interface or output interface for fluid media such as fuel, coolant, etc. in these cylinders or pump bodies. One end of the connector 10 is a fixed end 10a, which is generally pre-fixed on the cylinder or pump body in the vehicle; the other end of the connector 10 is a socket end 10b, which has an insertion port 11, and the insertion port 11 is used to insert the plug 20.

[0067] The plug member 20 is used to connect between the connector 10 and the pipeline in the vehicle, so that the pipeline in the vehicle is connected to the cylinder or pump body in the vehicle through the plug member 20 and the connector 10. One end of the plug member 20 is a connection end 20a, which is generally pre-connected with the pipeline in the vehicle; the other end of the plug member 20 is a plug end 20b, which is used to be inserted into the connector 10.

[0068] The connecting assembly 30 is used to fix the plug component 20 and the connector component 10 so that the plug component 20 and the connector component 10 can be firmly connected.

[0069] Continue to see Figure 2 As shown, the outer wall of the connector 10 has a first flange 12 , and the outer wall of the plug 20 has a second flange 21 and a third flange 22 , with a slot 23 formed between the second flange 21 and the third flange 22 .

[0070] Continue to see Figure 2 As shown, the connection assembly 30 includes a connection ring 31 and a snap ring 32 . The connection ring 31 is sleeved on the outside of the connector 10 and the plug 20 , and the snap ring 32 is sleeved on the outside of the connection ring 31 .

[0071] Continue to see Figure 2 and Figure 5 As shown, the inner wall of the connecting ring 31 has a first latching tooth 311 which is latched into the latching groove 23 ; the outer wall of the connecting ring 31 has a protrusion 312 which is located at two ends of the connecting ring 31 opposite to the first latching tooth 311 and the protrusion 312 .

[0072] Continue to see Figure 2 and Figure 5 As shown, the inner side wall of the snap ring 32 has a second locking tooth 321 , and the second locking tooth 321 is engaged with the first flange 12 ; the end of the snap ring 32 facing the connector 10 has a notch 322 , and the protrusion 312 is engaged with the notch 322 .

[0073] When assembling the connector device, the plug end 20b of the plug member 20 is gradually passed through the connecting ring 31, and the first latching tooth 311 of the connecting ring 31 contacts the second flange 21 of the plug member 20 and is pressed outward by the second flange 21 until the first latching tooth 311 passes through the second flange 21 and is inserted into the slot 23 formed by the second flange 21 and the third flange 22, so that the plug member 20 is connected to the connecting ring 31. At this time, the first latching tooth 311 is blocked by the second flange 21 and the third flange 22 and cannot escape from the slot 23, but the first latching tooth 311 can move along the direction in which the slot 23 extends, so the connecting ring 31 can rotate relative to the plug member 20.

[0074] After the plug 20 is connected to the connecting ring 31, the plug end 20b of the plug 20 is inserted into the connector 10 through the insertion port 11 of the connector 10. Then, the snap ring 32 is gradually moved from the connecting end 20a of the plug 20 to the plug end 20b of the plug 20 until the protrusion 312 of the outer wall of the connecting ring 31 is engaged with the notch 322 of the snap ring 32, and the snap ring 32 is continuously moved so that the second snap teeth 321 of the snap ring 32 are in contact with the first flange 12 of the connector 10 and are pressed outward by the first flange 12 until the second snap teeth 321 pass through the first flange 12 and engage with the first flange 12. At this time, the snap ring 32 is restricted between the protrusion 312 and the first flange 12, the protrusion 312 is located on the connecting ring 31 connected to the plug 20, the first flange 12 is located on the connector 10, and the plug 20 and the connector 10 are connected to the snap ring 32 through the connecting ring 31. The freedom of the snap ring 32 is limited only in the direction in which the plug 20 is inserted into the connector 10 , so the snap ring 32 can rotate relative to the plug 20 and the connector 10 together with the connecting ring 31 .

[0075] Therefore, in the connector device provided by the embodiment of the present application, the snap ring 32 of the connector device can rotate relative to the plug member 20 and the connector member 10. Even if the snap ring 32 is located in some narrow spaces in the vehicle, when removing the snap ring 32, the snap ring 32 can be rotated to a direction that is convenient for observation and easy for fingers to operate, so that the snap ring 32 can be easily removed.

[0076] In addition, in actual use, the connecting ring 31 can be retained on the plug member 20, that is, when the connector device is disassembled, the connecting ring 31 is not removed from the plug member 20. In this way, when the plug member 20 needs to be connected to the connector 10 again, it is only necessary to insert the plug member 20 into the connector 10 and connect the plug member 20 to the connector 10 through the clamping ring 32, thereby realizing the rapid installation and removal of the plug member 20 and the connector 10.

[0077] Figure 6 A schematic diagram of the structure of a connector in a connector device provided in an embodiment of the present application; Figure 7 Schematic diagram of the structure of the plug member in the connector device provided in the embodiment of the present application Figure 1 ; Figure 8 Schematic diagram of the structure of the plug member in the connector device provided in the embodiment of the present application Figure 2 .

[0078] See also Figure 2 , Figure 5 and Figure 6As shown, the connector 10 is a hollow tube, and the connector 10 is generally made of metal materials such as steel alloy, copper alloy, etc. The fixed end 10a of the connector 10 is connected to the cylinder body or pump body of the vehicle by threading or welding, and the inside of the connector 10 is connected to the cylinder body or pump body of the vehicle. The first flange 12 is located at the socket end 10b of the connector 10, and the first flange 12 extends from the socket end 10b of the connector 10 to the peripheral side of the connector 10.

[0079] See also Figure 2 , Figure 5 and Figure 7 As shown, the plug member 20 is a hollow tube, and the plug member 20 is generally made of metal materials such as steel alloy and copper alloy. The connecting end 20a of the plug member 20 is inserted into the pipeline in the vehicle so that the plug member 20 is connected to the pipeline in the vehicle. The second flange 21 and the third flange 22 are located between the connecting end 20a and the plug end 20b of the plug member 20. The first flange 12 protrudes outward from the outer side wall of the plug member 20, and the second flange 21 protrudes outward from the outer side wall of the plug member 20, and the first flange 12 is parallel to the second flange 21.

[0080] Continue to see Figure 7 As shown, the outer wall of the plug member 20 has an annular groove 24, which is located between the plug end 20b and the second flange 21, and the sealing ring 40 can be placed in the annular groove 24. In this way, when the plug member 20 is inserted into the connector 10, the sealing ring 40 abuts against the outer wall of the plug member 20 and the inner wall of the connector 10, so that the sealing ring 40 can seal the gap between the outer wall of the plug member 20 and the inner wall of the connector 10, thereby ensuring the sealing performance of the connector device.

[0081] Specifically, the sealing ring 40 may be a rubber sealing ring 40 or a silicone sealing ring 40 or the like.

[0082] See also Figure 7 and Figure 8 As shown, the portion between the connecting end 20a of the plug 20 and the second flange 21 can be in a straight tube shape, a curved tube shape, etc. Figure 7 As shown, the portion between the connecting end 20a of the plug 20 and the second flange 21 is a straight tube. Figure 8 As shown, the portion between the connecting end 20a of the plug member 20 and the second flange 21 may be in the shape of a curved tube.

[0083] Fig. 9 A schematic diagram of a connector of a connecting ring in a connector device provided in an embodiment of the present application; Fig.10 A schematic top view of a connecting ring in a connector device provided in an embodiment of the present application.

[0084] See also Figure 2 , Figure 5 , Fig. 9and Fig.10 As shown, in the embodiment of the present application, one end of the connecting ring 31 facing the connector 10 has an escape opening 313 , and the second latching tooth 321 passes through the escape opening 313 and is engaged with the first flange 12 .

[0085] The avoidance opening 313 is used for the second latching tooth 321 to pass through so as to be engaged with the first flange 12. In this way, the second latching tooth 321 does not need to fully extend to the lower end of the connecting ring 31, and then bypass the connecting ring 31 to be engaged with the first flange 12, so that the structure of the second latching tooth 321 is simpler and the connection is more convenient. It also makes the structure between the snap ring 32 and the connecting ring 31 more compact and does not occupy too much space.

[0086] In the embodiment of the present application, the number of protrusions 312 is at least two, and the at least two protrusions 312 are spaced apart along the circumference of the connecting ring 31 ; the number of notches 322 is at least two, and the positions of the at least two notches 322 correspond to the positions of the at least two protrusions 312 .

[0087] Specifically, the protrusion 312 is a convex block protruding outward from the outer wall of the connecting ring 31, and there are four protrusions 312, which are symmetrically distributed. There are three notches 322, two of which correspond to the two protrusions 312 on one side of the connecting ring 31 and are respectively inserted therein, and the remaining notch 322 corresponds to the two protrusions 312 on the other side of the connecting ring 31 and is inserted thereinto together.

[0088] The plurality of protrusions 312 are inserted into the notches 322 of the snap ring 32 , so that the force between the snap ring 32 and the connecting ring 31 is more uniform, thereby preventing a single protrusion 312 from breaking due to excessive force.

[0089] In the embodiment of the present application, there are multiple first latching teeth 311 , and the multiple first latching teeth 311 are evenly distributed along the circumference of the inner side wall of the connecting ring 31 .

[0090] The first latch teeth 311 are evenly distributed along the circumference of the inner wall of the connecting ring 31 , so that each first latch tooth 311 can be stably inserted into the latch groove 23 , and can ensure that each first latch tooth 311 is subjected to uniform force, thereby preventing a single first latch tooth 311 from breaking due to excessive force, and ensuring a stable connection between the connecting ring 31 and the plug component 20 .

[0091] See also Figure 2 , Figure 5 , Fig. 9 and Fig.10As shown, in the embodiment of the present application, the first latching tooth 311 has an inclined surface on one side facing the inner side of the connecting ring 31, so that when the connecting ring 31 is connected to the plug 20, the first latching tooth 311 of the connecting ring 31 contacts the second flange 21 of the plug 20, and the second flange 21 applies an outward expansion force to the first latching tooth 311 through the inclined surface on the first latching tooth 311, so that the first latching tooth 311 is pushed outward until the first latching tooth 311 passes through the second flange 21 and is clamped into the clamping groove 23 formed by the second flange 21 and the third flange 22. In this way, the connection between the connecting ring 31 and the plug 20 can be facilitated.

[0092] In addition, in order to prevent the first latch 311 from escaping from the slot 23, the protruding length of the third flange 22 is greater than the protruding length of the second flange 21. In this way, the inclined surface of the first latch 311 cannot contact the edge of the third flange 22, preventing the first latch 311 from escaping from the slot 23 through the third flange 22.

[0094] See 2. Figure 5 as well as Figures 11 to 13 As shown, in the embodiment of the present application, the snap ring 32 includes an elastic plate 32a, the elastic plate 32a is curved, and an opening 325 is formed between the two ends of the elastic plate 32a. The second locking tooth 321 is located on the inner side wall of the elastic plate 32a, and the end of the elastic plate 32a facing the connector 10 has a notch 322.

[0095] Specifically, the elastic plate 32a can be made of plastic with good elasticity, and the curvature of the elastic plate 32a generally corresponds to the curvature of the outer wall of the connecting ring 31, and the center line of the elastic plate 32a is colinear with the center line of the connecting ring 31. This allows the inner wall of the elastic plate 32a to better fit the outer wall of the connecting ring 31. When the snap ring 32 needs to be disassembled, an outward pulling force is applied to both ends of the elastic plate 32a to enlarge the opening 325 between the two ends of the elastic plate 32a until the second clamping tooth 321 no longer clamps the first flange 12, thereby separating the connector 10 from the snap ring 32, and then separating the snap ring 32 from the connecting ring 31, so that the snap ring 32 can be easily disassembled.

[0096] Continue to see Fig.13As shown, in the embodiment of the present application, the second tooth 321 has a beveled surface on one side facing the inner side of the retaining ring 32, so that when the retaining ring 32 is connected to the connector 10, the second tooth 321 of the retaining ring 32 contacts the first flange 12 of the connector 10, and the first flange 12 applies an outward expansion force to the second tooth 321 through the bevel on the second tooth 321, so that the second tooth 321 is pushed outward until the second tooth 321 is engaged with the first flange 12.

[0097] See also Figure 11-13 As shown, in the embodiment of the present application, the two ends of the elastic plate 32a respectively have a first toggle portion 323 and a second toggle portion 324 .

[0098] The first and second toggle parts 323 and 324 can be used as fulcrums. Compared with holding the two ends of the elastic plate 32a and applying force to expand the opening 325 between the two ends of the elastic plate 32a, holding the first and second toggle parts 323 and 324 can more conveniently expand the opening 325 between the two ends of the elastic plate 32a.

[0099] Continue to see Figure 11-13 As shown, in the embodiment of the present application, the first shifting part 323 includes a first shifting rod extending from the first end of the elastic plate 32a toward the opening 325. The second shifting part 324 includes a second shifting rod extending from the second end of the elastic plate 32a toward the opening 325.

[0100] The first lever extends outward from the first end of the elastic plate 32a toward the opening 325, which is equivalent to extending the first end of the elastic plate 32a. Similarly, the second lever extends outward from the second end of the elastic plate 32a toward the opening 325, which is equivalent to extending the second end of the elastic plate 32a. When the snap ring 32 needs to be removed, just pinch the first lever and the second lever to expand the opening 325 between the two ends of the elastic plate 32a. This makes the removal of the snap ring 32 more convenient and labor-saving.

[0101] In the embodiment of the present application, the first lever is located on the side of the second lever facing the connector 10 , and a side of the protrusion 312 facing the plug 20 abuts against a side of the first lever facing the connector 10 .

[0102] In this way, the side of the first lever facing the connector 10 can be used as a part of one of the notches 322 on the snap ring 32, for abutting against the protrusion 312. When the first lever is forcibly pried apart, until the first lever and the protrusion 312 are no longer abutted, the connection ring 31 and the snap ring 32 can be easily separated.

[0103] The embodiment of the present application provides a vehicle, including the above-mentioned joint device. The pipelines in the fuel system, cooling system and other systems of the vehicle are connected to the cylinder or pump body in each system through the above-mentioned joint device. When it is necessary to disconnect the pipeline in the vehicle from the cylinder or pump body in the vehicle, even if the clamping ring 32 is located in some small space in the vehicle, the clamping ring 32 can be rotated to a position that is easy to observe and easy to operate with fingers, so that the clamping ring 32 can be easily disassembled with fingers, so that the pipeline in the vehicle is disconnected from the cylinder or pump body in the vehicle.
