Description

Technical Field

[0001] The present application relates to the technical field of charging guns, and in particular to a liquid-cooled charging gun. Background Art

[0002] The core design principle of the liquid-cooled charging gun is to use the liquid cooling system to effectively reduce the heating problem during the charging process. Specifically, the liquid cooling system is integrated into the head of the liquid-cooled charging gun. The electronic pump drives the coolant to flow, taking away the heat generated by the current loss, and finally transferring the heat to the coolant tank, and then the electronic pump drives the radiator to dissipate the heat. This process is repeated to ensure that the charging gun maintains a low temperature when working.

[0003] The existing patent document with authorization announcement number CN219371448U discloses a liquid-cooled charging gun quick-change structure, which includes an eight-shell charger main body component and a quick-change gun connector head component, and the quick-change gun connector head component can be detachably installed on the charging connector main body component by fixing screws.

[0004] The quick-change gun connector head assembly is connected by means of fixing screws. The charging gun needs to be frequently plugged and unplugged during use. During the charging process, the gravity of the cable and the charging connector main assembly will make the connection between the quick-change gun connector head assembly and the charging connector main assembly susceptible to pulling force, which will easily weaken the connecting force of the fixing screws over time. Summary of the invention

[0005] In order to improve the stability of the connection of the charging gun, the present application provides a liquid-cooled charging gun.

[0006] This application adopts the following technical solutions: A liquid-cooled charging gun comprises a gun head, and a connector detachably connected to the gun head, wherein a connector is installed on the connector to connect the connector and the gun head together; the connector is provided with a ring edge, and the gun head is provided with an extension seat. When the gun head and the connector are connected together, the extension seat is inserted into the ring edge, and the side wall of the extension seat abuts against the inner wall of the ring edge, and the side wall of the extension seat is provided with a positioning member.

The positioning member includes a positioning rod slidably installed in the installation groove and an elastic member arranged in the installation groove. The inner wall of the ring edge is provided with a positioning groove for the positioning rod to be inserted. When the trigger member is inserted into the trigger groove, it can drive the positioning rod to slide and be inserted into the positioning groove. At this time, the elastic member is in a compressed state.

[0013] By adopting the above technical solution, the trigger member pushes the positioning rod to slide, so that the positioning rod is inserted into the positioning groove, thereby connecting the ring edge and the extension seat together, and relative sliding is not likely to occur, thereby improving the anti-pullout ability of the gun head.

[0014] Optionally, the trigger member includes a trigger ring arranged on the side of the connecting head facing the gun head, and when the trigger ring is inserted into the trigger groove, the outer wall of the trigger ring abuts against the inner wall of the trigger groove.

[0018] By adopting the above technical solution, the power source drives the abutment bar to bend and deform, so that the convex point on the outer wall of the abutment bar presses against the extension block and pushes the extension block to deform.

[0019] Optionally, the power source includes a push rod threadedly connected to the accommodating cavity, and when the push rod moves forward in the accommodating cavity, it can abut against a protrusion on the inner wall of the interference bar and push the interference bar to move in a direction close to the extension block.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-7 This application is described in further detail.

[0027] The present application embodiment discloses a liquid-cooled charging gun. Figure 1 and Figure 2 The charging gun includes a gun head 1 and a connector 2 detachably connected to the gun head 1. A connector 3 is provided between the connector 2 and the gun head 1, and the two are connected together through the connector 3. A plurality of connectors 3 are provided at intervals along the circumference of the connector 2.

[0028] A ring edge 4 is provided on the side of the connector 2 close to the gun head 1, and an extension seat 5 is provided on the gun head 1, and the terminals and other components on the gun head 1 extend from the extension seat 5. When the connector 2 and the gun head 1 are connected together, the extension seat 5 can be inserted into the inner cavity of the ring edge 4, and the outer wall of the extension seat 5 abuts against the inner wall of the ring edge 4, thereby limiting the possibility of the extension seat 5 shaking in the ring edge 4. A sealing ring can be provided at the end of the ring edge 4, and the sealing ring abuts against the gun head 1, thereby improving the sealing effect. A positioning member 6 is provided between the ring edge 4 and the extension seat 5, and the ring edge 4 and the extension seat 5 are connected by the positioning member 6, so that the extension seat 5 can be limited from detaching from the ring edge 4, thereby improving the stability of the connection between the gun head 1 and the connector 2.

[0029] Reference Figure 3 and Figure 4 The connecting member 3 includes a connecting rod 31 and an abutment seat 32 disposed at the end of the connecting rod 31. Figure 5 A thread groove 7 is provided on the gun head 1, and the connecting rod 31 passes through the connecting head 2 and is threadedly connected in the thread groove 7, thereby connecting the connecting head 2 and the gun head 1 together.

[0030] Reference Figure 3 and Figure 5 The extension seat 5 is provided with a trigger groove 8, which is coaxially arranged with the thread groove 7, and the trigger groove 8 passes through the surface of the extension seat 5 on the side away from the gun head 1. A trigger member 9 is installed on the connector 2. When the connector 2 is connected to the gun head 1, the trigger member 9 is inserted into the trigger groove 8 and drives the positioning member 6 to connect the ring edge 4 and the extension seat 5 together.

[0031] Reference Figure 5 and Figure 6 , the inner wall of the trigger groove 8 is provided with a mounting groove 10, and the mounting groove 10 passes through the outer wall of the extension seat 5. The positioning member 6 includes a positioning rod 61 slidably inserted into the mounting groove 10 and an elastic member 62 arranged on the outer wall of the positioning rod 61. The elastic member 62 is a spring, and the spring is sleeved on the outer wall of the positioning rod 61. In order to facilitate the installation of the spring, the mounting groove 10 can be a stepped structure, and the diameter of the end close to the trigger groove 8 is larger. One end of the spring abuts against the inner wall of the mounting groove 10, and the other end is connected to the side wall of the positioning rod 61. Under the action of the elastic member 62, one end of the positioning rod 61 extends into the trigger groove 8. A positioning groove 11 is provided on the inner wall of the ring edge 4, and the positioning groove 11 corresponds to the positioning rod 61 one by one, and the cross-section of the positioning groove 11 is a right-angled triangle structure, so that the positioning rod 61 is easier to insert into the positioning groove 11. After the gun head 1 and the connector 2 are connected, the end of the positioning rod 61 abuts against the side wall of the positioning groove 11. When the trigger member 9 drives the positioning rod 61 to slide, the end of the positioning rod 61 can be inserted into the positioning groove 11, so that the ring edge 4 and the extension seat 5 are connected together. Further, the length direction of the positioning rod 61 is perpendicular to the length direction of the connecting rod 31.

[0032] Reference Figure 3 and Figure 5 The trigger member 9 is a trigger ring 91 fixed on the connector 2. When the connector 2 is mounted on the gun head 1, the trigger ring 91 is inserted into the trigger groove 8 and drives the positioning rod 61 to slide. Furthermore, the outer diameter of the trigger ring 91 is the same as the inner diameter of the trigger groove 8, so that when the trigger ring 91 is inserted into the trigger groove 8, the outer wall of the trigger ring 91 abuts against the inner wall of the trigger groove 8.

[0033] Reference Figure 5 and Figure 6 A plurality of extension blocks 12 are fixed in the bottom surface of the trigger groove 8. The extension blocks 12 are arranged at intervals along the circumference of the trigger groove 8, and there is a gap between adjacent extension blocks 12. The extension blocks 12 have a certain deformation ability. When the trigger ring 91 is inserted into the trigger groove 8, the extension block 12 is located in the inner cavity of the trigger ring 91. An annular groove 13 is provided on the inner wall of the trigger ring 91, and a hook block 14 is fixed on the outer wall of the end of the extension block 12. A driving member 15 is provided on the connecting rod 31, and the driving member 15 can drive the extension block 12 to move in the direction close to the inner wall of the trigger ring 91, so that the hook block 14 can abut against the annular groove 13. When subjected to a pulling force, the hook block 14 transfers the force to the trigger ring 91, thereby further improving the pull-out resistance of the gun head 1 and the connector 2.

[0034] Reference Figure 6 and Figure 7 , a receiving chamber 16 is provided in the connecting rod 31, and the receiving chamber 16 is connected to the surface of the abutment seat 32. The outer wall of the connecting rod 31 is provided with a slot 18 that is connected to the receiving chamber 16, and 6 slots 18 are evenly arranged along the circumference of the connecting rod 31. The driving member 15 includes a contact strip 151 fixed in each slot 18, one end of the contact strip 151 is fixed on the inner wall of the slot 18 away from the abutment seat 32, and there is a gap between the contact strip 151 and the inner wall of the slot 18, and the contact strip 151 also has a certain deformation ability. The driving member 15 also includes a power source 152 installed in the receiving chamber 16, and the power source 152 is used to drive the contact strip 151 to move. Both the inner and outer sides of the contact strip 151 are fixed with convex points 17. The power source 152 moves in the receiving chamber 16 and contacts the convex points 17, thereby pushing the contact strip 151 outward. The protrusion 17 on the outer wall of the abutment strip 151 abuts against the extension block 12, and drives the extension block 12 to move, so that the hook block 14 abuts against the annular groove 13. The number of the extension blocks 12 exceeds the number of the abutment strips 151. When the connecting rod 31 is adjusted to a reasonable position, the abutment strips 151 can better cooperate with the adjacent extension blocks 12.

[0035] The power source 152 includes a push rod threadedly connected to the accommodating chamber 16. One end of the push rod can be provided with a slot or a cross slot, so that it is convenient to use a tool to rotate the push rod. When the push rod moves forward in the accommodating chamber 16, it can abut against the convex point 17 on the inner wall of the abutting strip 151, thereby pushing the abutting strip 151 outward. Furthermore, one end of the push rod abutting against the convex point 17 is set as an arc structure, which is more convenient to push the movement of the abutting strip 151.

[0036] The implementation principle of a liquid-cooled charging gun in an embodiment of the present application is as follows: when the connector 2 and the gun head 1 are connected together, the stability of the connection between the two can be improved under the joint action of the positioning rod 61 and the connecting rod 31. In addition, the extension block 12 and the trigger ring 91 are connected together by the hook block 14, which further improves the pull-out resistance when the two are connected.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
