Description

Technical Field

[0001] The utility model belongs to the technical field of automobile charging connectors, and in particular relates to a locking structure of a charging gun adapter. Background Art

[0002] A charging gun adapter is a device used to connect different types of electric vehicles and charging piles. It often has socket terminals and plug terminals at both ends. The socket terminals and plug terminals contact the charging gun head of the charging pile and the charging socket of the car respectively, thereby meeting the intercompatibility of the physical connections of various standard charging interfaces.

[0003] In order to ensure that the charging gun head can be stably connected to the socket terminal, a locking structure is designed at the socket terminal, as shown in the attached Figure 1 and attached Figure 2 As shown, most of the existing locking structures adopt a lock-type structure, which mainly includes a pressure rod and a spring. The middle part of the pressure rod is rotatably connected to the adapter body. The front end of the pressure rod is provided with a clamping head, and the rear end of the pressure rod abuts against the adapter body through a spring. When the charging gun head is inserted into the socket terminal, under the pressure of the spring, the clamping head at the front end of the pressure rod penetrates into the inside of the socket terminal and clamps the clamping mouth on the charging gun head, so that the charging gun head can be locked on the adapter body; similarly, pressing the rear end of the pressure rod can drive the clamping head out of the clamping mouth to release the restriction on the charging gun head.

[0004] Since the clamp head is mainly driven to engage with the bayonet by the pressure of the spring, the installation tightness of the charging gun head is entirely determined by the elasticity of the spring; if the spring force is too small, the clamp head cannot be tightly engaged with the bayonet, causing the charging gun head to be easily pulled out directly; if the spring force is too large, it is difficult for the user to press the pressure rod to drive the clamp head out of the bayonet, and the actual use experience is poor.

[0042] See attached Figure 3 -Attached Figure 11 , a locking structure of a charging gun adapter, which includes a fixing base 3, a slider 4, a locking rod 5 and a driving part 6; the fixing base 3 is installed at the socket terminal 21 of the adapter body 2, and a movable groove 30 is provided inside the fixing base 3, and a sleeve cavity 210 for plugging the charging gun head 1 is provided inside the socket terminal 21; the slider 4 is slidably installed in the movable groove 30, and a clamping head 41 is provided at the bottom end of the slider 4, and the clamping head 41 can slide with the slider 4 to pass through the bottom wall of the movable groove 30 and enter and exit the sleeve cavity 210 to clamp or disengage the bayonet 11 of the charging gun head 1; the locking rod 5 is movably installed in the fixing base 3, and a pressure block 51 is provided on the first end of the locking rod 5; the driving part 6 is installed in the fixing base 3 and is drivingly connected to the locking rod 5 to drive the pressure block 51 in and out of the movable groove 30 to tighten or release the slider 4.

[0043] Specifically, under normal circumstances, the slider 4 moves downward under the influence of its own gravity, so that the clamping head 41 remains in the sleeve cavity 210, and the pressing block 51 on the locking rod 5 is located outside the movable groove 30 and releases the slider 4, ensuring that the slider 4 can move up and down smoothly;

[0044] When the user inserts the charging gun head 1 into the sleeve cavity 210, the clamping head 41 will be driven to move upward and out of the sleeve cavity 210 first. After it is fully inserted into place, the bayonet 11 on the charging gun head 1 is precisely aligned with the clamping head 41, so that the clamping head 41 is suspended in the air. The clamping head 41 moves downward under the influence of its own gravity and engages with the bayonet 11. At this time, the driving part 6 drives the locking rod 5 to move close to the movable groove 30, so that the pressure block 51 enters the movable groove 30 and presses against the slider 4 to limit the up and down movement of the clamping head 41 and disengage from the bayonet 11, thereby fixing the charging gun head 1 in the sleeve cavity 210, thereby achieving a stable connection between the charging gun head 1 and the adapter body 2.

[0045] When the charging gun head 1 needs to be removed from the adapter body 2, the driving part 6 is first used to drive the locking rod 5 away from the movable groove 30, so that the pressure block 51 is disengaged from the movable groove 30 and the slider 4 is released to release the restriction on the clamping head 41. At this time, the user directly pulls the charging gun, and under the action of force, the clamping head 41 will gradually disengage from the bayonet 11 until the charging gun head 1 is removed from the sleeve cavity 210.

[0046] It should be noted that in order to make it easier for the clamping head 41 to enter and exit the clamping port 11, the user can adaptively invert the adapter body 2 during the disassembly process. For example, after releasing the restriction of the pressure block 51 on the clamping head 41, the user can directly invert the adapter body 2 so that the clamping head 41 moves under the action of gravity and disengages from the clamping port 11, thereby facilitating direct disassembly of the charging gun head 1.

[0047] To sum up, the present invention designs a movable groove 30 on the fixing seat 3 for the movement of the slider 4, so that the clamping head 41 can enter and exit the sleeve cavity 210 and be engaged or disengaged from the clamping mouth 11, and designs a driving part 6 on the fixing seat 3 to drive the locking rod 5 to move, so that the pressure block 51 can enter and exit the movable groove 30 and tighten or loosen the slider 4; under this structural design, the user only needs to adjust the position of the locking rod 5 through the driving part 6 to realize the plugging and unplugging between the charging gun head 1 and the adapter body 2, thereby improving the operational convenience. In addition, with the cooperation of the pressure block 51 and the slider 4, the charging gun head 1 can also be more stably plugged into the adapter body 2, thereby improving the overall user experience.

[0048] See attached Figure 8 -Attached Figure 14 The end of the clamping head 41 close to the clamping port 11 is rounded.

[0049] Specifically, during the process of the charging gun head 1 entering the sleeve cavity 210, the top surface of the charging gun head 1 contacts the circular surface of the clamp head 41 and drives the clamp head 41 to move up in the height direction of the movable groove 30. Similarly, during the process of the clamp head 41 moving out of the bayonet 11, the top edge of the side wall of the bayonet 11 contacts the circular surface of the clamp head 41 and drives the clamp head 41 to move up in the height direction of the movable groove 30. Therefore, the chamfered design of the end of the clamp head 41 can avoid the clamp head 41 hindering the movement of the charging gun head 1. On the one hand, it can enable the charging gun head 1 to enter the sleeve cavity 210 smoothly, and on the other hand, it can prevent the clamp head 41 from being stuck and fixed in the bayonet 11, ensuring that the charging gun head 1 can be smoothly pulled out of the sleeve cavity 210.

[0050] See attached Figure 7 -Attached Figure 15 The first end of the slider 4 is provided with a first elastic member 42 abutting against the top wall of the movable groove 30 .

[0051] Specifically, under normal circumstances, the first elastic member 42 is in the initial state and restricts the clamping head 41 in the sleeve cavity 210; when the charging gun head 1 is inserted into the sleeve cavity 210, the charging gun head 1 drives the clamping head 41 to move upward and squeezes the first elastic member 42 until the bayonet 11 is aligned with the clamping head 41, and then the first elastic member 42 releases energy to recover and drives the clamping head 41 to move downward to engage the bayonet 11; similarly, when the charging gun head 1 is pulled out of the sleeve cavity 210, the first elastic member 42 is also deformed first and then recovered.

[0052] Therefore, the design of the first elastic member 42 can prevent the slider 4 from shaking at will, improve the installation stability of the clamping head 41, and at the same time, provide a certain sense of blockage and relaxation when the user plugs in and out the charging gun head 1, and has a sound prompt, which can give the user good operation feedback, making it convenient for the user to judge whether the charging gun head 1 is plugged in place, further improving the user experience.

[0053] The first elastic member 42 may be a rubber sleeve, a spring or other component with deformation and recovery capabilities.

[0054] See attached Figure 7 -Attached Figure 15 There are many ways to move the connection between the locking rod 5 and the fixed base 3, and most of them are common knowledge. Therefore, the present invention does not impose any restrictions on this. For the sake of convenience, in this embodiment, a slide groove 31 connected to the movable groove 30 is provided inside the fixed base 3, and a guide column 32 perpendicular to the length direction of the slide groove 31 is installed in the slide groove 31; the locking rod 5 is located in the slide groove 31, and a key hole 52 is provided on the locking rod 5, and the key hole 52 is slidably matched with the guide column 32 to prevent the locking rod 5 from disengaging from the slide groove 31, and the locking rod 5 can be movably installed in the slide groove 31.

[0055] Specifically, the user can use the driving part 6 to drive the locking rod 5 to move closer to the movable groove 30 along the length direction of the slide groove 31, so that the pressure block 51 enters the movable groove 30 and locks the slider 4 to limit the up and down movement of the clamping head 41 in the height direction of the movable groove 30; or use the driving part 6 to drive the locking rod 5 away from the movable groove 30 along the length direction of the slide groove 31, so that the pressure block 51 disengages from the movable groove 30 and releases the slider 4 to release the movement restriction of the clamping head 41.

[0056] See attached Figure 12 The adapter body 2 is provided with a recessed accommodating chamber 22, and a pillar 23 is provided in the accommodating chamber 22. The fixing seat 3 is adaptively installed in the accommodating chamber 22, and a bolt 33 threadedly connected to the pillar 23 is rotatably installed on the fixing seat 3; a through hole 221 connected to the sleeve cavity 210 is opened on the bottom wall of the accommodating chamber 22, and the clamping head 41 can enter and exit the sleeve cavity 210 through the through hole 221.

[0057] Specifically, the recessed design of the accommodating cavity 22 can prevent the fixing base 3 from protruding too much from the adapter body 2 and affecting the aesthetics, while reducing the overall volume; the coordinated use of the support 23 and the bolt 33 facilitates the disassembly, assembly and maintenance of the fixing base 3; and the through hole 221 is an adaptive design and will not be elaborated here.

[0058] Furthermore, positioning holes 222 are provided on both side walls of the accommodating cavity 22, and both ends of the guide column 32 extend and plug into the two positioning holes 222 respectively; this design can increase the contact area between the fixing base 3 and the adapter body 2, ensuring that the fixing base 3 can be more stably installed in the accommodating cavity 22, thereby improving the impact resistance of the fixing base 3.

[0059] See attached Figure 6 -Attached Figure 15 Currently, the driving parts 6 on the market are mainly divided into electric and manual types, and the related types are diverse, so this utility model does not limit this. For the sake of ease of understanding, here are examples of the two types of driving parts 6:

[0060] First, the driving part 6 adopts an electric cylinder (not shown in the figure), which is installed in the fixed seat 3, and the telescopic end of the electric cylinder is fixedly connected to the locking rod 5 to drive the locking rod 5 to move along the length direction of the slide groove 31; the electric cylinder is controlled by a program and can run after being powered on, so this driving part 6 is electric. Similar electric driving parts 6 also include screw motors, etc.

[0061] Second, as attached Figure 6 -Attached Figure 15As shown, the driving part 6 includes a rotating wheel 61, a second elastic member 62 and a knob 63. A rotating cavity 34 connected to the slide groove 31 is also provided inside the fixed seat 3, and a first baffle 31d is provided in the slide groove 31 to avoid the pressure block 51; the rotating wheel 61 is located in the rotating cavity 34 and corresponds to the second end of the locking rod 5; a second baffle 5d corresponding to the first baffle 31d is provided inside the locking rod 5, and the two ends of the second elastic member 62 respectively abut the first baffle 31d and the second baffle 5d; the knob 63 is rotatably mounted on the fixed seat 3, and one end of the knob 63 extends to the rotating cavity 34 to fix the rotating wheel 61 and form a cam structure with a protruding end; wherein, rotating the knob 63 can drive the rotating wheel 61 to rotate in the rotating cavity 34, thereby causing the protruding end of the cam structure to abut or move away from the second end of the locking rod 5 to drive the locking rod 5 to move along the length direction of the slide groove 31, and the second elastic member 62 will adaptively deform and recover during this process.

[0062] Specifically, when the user turns the knob 63 to drive the rotating wheel 61 and makes the protruding end of the cam structure abut against the second end of the locking rod 5, the locking rod 5 can be driven to move closer to the movable groove 30 along the length direction of the sliding groove 31, directly pressing the block 51 against the slider 4, and in this process, the second elastic member 62 is squeezed and deformed by the first baffle 31d and the second baffle 5d to store energy; when the user turns the knob 63 to drive the rotating wheel 61 and makes the protruding end of the cam structure move away from the second end of the locking rod 5, the second elastic member 62 releases energy to recover and drives the locking rod 5 to reset, so that the block 51 is separated from the slider 4.

[0063] Since the locking rod 5 is driven by the user manually turning the knob 63 , the driving unit 6 is a manual type. Compared with the electric driving unit 6 , the manual driving unit 6 not only saves manufacturing costs, but is also easier to maintain and more durable.

[0064] The second elastic member 62 may be a rubber sleeve, a spring or other component with deformation and recovery capabilities.

[0065] See attached Figure 7 , Attachment Figure 11 and attached Figure 16 The rotating wheel 61 can be fixed to the knob 63 by means of snap connection, bonding, etc. There are various related installation methods, which are not limited in the present invention. For the convenience of understanding, in this embodiment, a polygonal socket 611 is provided on the rotating wheel 61, and an insertion shaft 630 is provided on the knob 63. A polygonal plug block 631 adapted to the plug socket 611 is provided on the insertion shaft 630, and the axis of the insertion shaft 630 is staggered from the axis of the rotating wheel 61. A fastening bolt 610 threadedly connected to the insertion shaft 630 can also be rotatably installed on the rotating wheel 61.

[0066] Specifically, during assembly, first insert the shaft 630 into the rotating wheel 61 and make the insert block 631 engage with the socket 611. Since the insert block 631 and the socket 611 are both polygonal, the rotating wheel 61 is prevented from rotating relative to the knob 63. After the insert block 631 engages with the socket 611, the fastening bolt 610 is screwed to connect the shaft 630, so that the rotating wheel 61 can be fixed on the knob 63. In addition, the axis of the shaft 630 is staggered from the axis of the rotating wheel 61, so that the knob 63 and the rotating wheel 61 form a cam structure after installation. Compared with other installation methods, this structure is more convenient for disassembly and assembly between the knob 63 and the rotating wheel 61.

[0067] See attached Figure 12 -Attached Figure 16 , an indicator mark 63b is provided on the knob 63, and a locking mark 35 and an unlocking mark 36 corresponding to the indicator mark 63b are provided on the side of the knob 63 of the fixing base 3; when the indicator mark 63b is aligned with the locking mark 35, the pressing block 51 is located in the movable groove 30 and presses against the slider 4; when the indicator mark 63b is aligned with the unlocking mark 36, the pressing block 51 is located outside the movable groove 30 and releases the slider 4; therefore, the coordinated design of the indicator mark 63b, the locking mark 35 and the unlocking mark 36 enables the user to clearly know the position of the locking rod 5, thereby facilitating the user to control the timing of plugging and unplugging the charging gun head 1.

[0068] It should also be noted that although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
