[0053] Now, with reference to the accompanying drawings, specific embodiments of the present invention will be described in detail. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on these preferred embodiments, and such other ways also fall within the scope of the present invention.

[0054] Figures 1-5A preferred embodiment of the charging gun holder and charging gun according to this utility model is shown. It should be noted first that the directional and positional terms used in this utility model should be understood as relative rather than absolute concepts. The directional and positional terms of this utility model can be referenced... Figures 1-5 The placement shown is for illustrative purposes. Unless otherwise specified, the description of the charging gun's position should be understood as its position when it is engaged with and fixedly supported by the charging gun holder.

[0055] First refer to Figure 1 In some preferred embodiments, a charging gun holder 21 is provided, which is configured to carry a charging gun 10 for charging an electric vehicle. The charging gun holder 21 can be part of a charging station; it can be manufactured, purchased, and installed separately onto the charging station, or it can be directly machined onto the charging station. The charging gun holder 21 includes a body portion 20, which defines a receiving cavity 23 (see...). Figure 2 The receiving cavity 23 has an opening 22 on one side, which is oriented so that the charging gun head 13 of the charging gun 10 can enter the receiving cavity 23 through the opening 22 in a first direction. The charging gun 10 includes a charging gun head 13 and a charging gun rod 12. The charging gun rod 12 is provided with a grip portion 121 for the user to hold, and the grip portion 121 is formed with anti-slip texture.

[0056] refer to Figure 2 The receiving cavity 23 includes a first segment 231, a second segment 232, and a third segment 233 connected in sequence. The opening 22 is located on the side of the first segment 231 away from the second segment 232. The inner diameter of the first segment 231 is larger than the inner diameter of the third segment 233. The second segment 232 transitions from the first segment 231 to the third segment 233. Correspondingly, the charging gun head 13 includes a gun head body 131 connected to the charging gun rod 12 and a gun head end 132 located on the side of the gun head body 131 away from the charging gun rod 12. The outer diameter of the gun head end 132 is smaller than the outer diameter of the gun head body 131. The gun head end 132 is correspondingly located in the second segment 232 and the third segment 233, and the gun head body 131 is correspondingly located in the first segment 231.

[0057] The charging gun head 13 is provided with a limiting portion, which is located within the receiving cavity 23 at a position away from the opening 22. The limiting portion extends perpendicularly to the first direction and engages with a corresponding portion of the charging gun head 13. Specifically, in this embodiment, the limiting portion is located at the junction of the second section 232 and the third section 233. In this embodiment, the limiting portion is a protrusion 24 located at the top, and the corresponding portion of the charging gun 10 is a groove 1321. In other embodiments not shown, the limiting portion can be a groove, and the corresponding portion of the charging gun can be a protrusion.

[0058] The limiting part prevents the charging gun head 13 from dislodging from the receiving cavity 23. Through the cooperation of the protrusion 24 forming the limiting part and the groove 1321 of the charging gun 10, the position of the charging gun 10 relative to the charging gun holder 21 is fixed as follows: Figure 1 and Figure 2 As shown, the full and stable engagement of the protrusion 24 and the groove 1321 is achieved based on the gravity-assisted lever principle of the charging gun lever 12. See details... Figure 2 The length of the charging gun rod 12 is much greater than the dimension of the charging gun head 13 in its extension direction, and the charging gun rod 12 and the charging gun head 13 form an obtuse angle, for example, 120°-160°. Taking the lowest contact point at the opening 22 of the charging gun 10 and the charging gun base 21 as the fulcrum F, the charging gun 10 forms a lever. The force G1 of this lever is, for example, the gravity of the charging gun rod 12, and the force arm D1 is the perpendicular line drawn from the fulcrum F to the direction of the gravity of the charging gun rod 12. Figure 2 For illustrative purposes only, the actual charging gun lever 12 is very long, so the direction of the weight of the charging gun lever 12 should actually be further to the left, and the power arm D1 should be longer; the resistance G2 of this lever includes the weight of the charging gun head 13 (and may also include the downward pressure exerted on the charging gun head 13 by the top wall of the receiving cavity 23), and the resistance arm D2 is the perpendicular line drawn from the fulcrum F to the direction of the weight of the charging gun head 13. Because the power arm D1 is very long, therefore, in situations where... Figure 2 In the state shown, the charging gun head 13 has a tendency to move upward relative to the charging gun base 21 about the fulcrum F. This upward movement ensures that the protrusion 24 and the groove 1321 are pressed together and cannot disengage.

[0059] Preferably, the limiting part is the only mechanism provided on the charging gun holder 21 for fixing the charging gun head 13 in the receiving cavity 23. That is to say, the present invention can omit conventional locking buttons and other settings for fixing the charging gun 10 to the charging gun holder 21.

[0060] Figures 2-4 The process of removing the charging gun 10 from the charging gun holder 21 is shown. When it is necessary to remove the charging gun 10 from the charging gun holder 21, the user can manipulate the charging gun 10 so that the charging gun 10 is within the plane defined by the first direction and the extending direction of the limiting portion (i.e., Figures 2-4 The plane shown is rotated so that the protrusion 24 and the groove 1321 disengage. Figures 2-3 The transformation illustrates this process. From Figure 2As can be seen, when the charging gun 10 is placed on the charging base, the top and bottom of the third section 233 are in contact with the charging gun head 13. The bottom of the first section 231 is in contact with the charging gun head 13, but there is a gap between the top and the charging gun head 13. There are gaps between each part of the second section 232 and the charging gun head 13. When the user lifts the charging gun lever 12 upwards, the charging gun 10 rotates approximately around the fulcrum F. During this process, when the top of the charging gun head 13 contacts the top of the first section 231 (see...),... Figure 3 The limiting part and the corresponding part of the charging gun head 13 disengage.

[0061] After the protrusion 24 and the groove 1321 disengage, the user can maintain the angle of the charging gun 10 relative to the charging gun base 21 and move the charging gun head 13 outward, so that the charging gun 10 leaves the receiving cavity 23. Figures 3-4 The transformation illustrates this process. Preferably, the charging gun holder 21 does not have a release mechanism (such as a release button) for releasing the charging gun 10 from the charging gun holder 21; the user can release the charging gun 10 from the charging gun holder 21 simply by lifting the charging gun lever 12 upwards.

[0062] exist Figures 2-4 During the process, the charging gun head 13 has two angular positions relative to the charging gun base 21— Figure 2 The charging gun head 13 is shown to have a first angular position relative to the charging gun base 21; Figure 3 and Figure 4 The second angular position of the charging gun head 13 relative to the charging gun base 21 is shown. The relationship between these two angular positions is... Figure 5 As shown in the image.

[0063] refer to Figure 5 P2 shows the first angular position of the charging gun head 13 relative to the charging gun holder 21. It should be noted that P2 is only used to show the angle and does not necessarily show the actual position of the charging gun head 13. In reality, when the charging gun head 13 is in the first angular position relative to the charging gun holder 21, the position of the charging gun head 13 relative to the charging gun holder 21 is as follows: Figure 2 As shown, it is understandable. Figure 2 The charging gun head 13 and Figure 5 The charging gun head 13 at position P2 has the same angle relative to the charging gun base 21, only the horizontal position is different. Figure 5 P1 in the diagram shows the second angular position of the charging gun head 13 relative to the charging gun base 21. P1 approximately corresponds to... Figure 3 and Figure 4The angular position of the charging gun head 13 relative to the charging gun base 21. The included angle between P1 and P2 is 15°. It can be understood that when the charging gun rod 12 rotates upward by 15°, the limiting part of the charging gun base 21 of the charging pile and the corresponding part of the charging gun head 13 disengage, and the charging gun head 13 can be moved out. In other embodiments not shown, the charging gun rod 12 is positioned as follows: Figure 2-5 When rotated upwards by 5°-20° in the plane shown, the limiting part of the charging gun base 21 of the charging pile and the corresponding part of the charging gun head 13 disengage.

[0064] The dimensions of the various structures in the above embodiments can be preferably configured. For example, the dimensions of the receiving cavity 23 can be preferably configured such that, more specifically, in the first direction, the length of the first segment 231 accounts for 2 / 3 to 5 / 6 of the total length of the receiving cavity 23. Similarly, preferably, the length of the limiting portion in its extending direction is 1 / 8 to 1 / 5 of the length of the third segment 233 in its extending direction. In fact, the gap value between the top surface 1312 of the charging gun head 13 and the top of the first segment 231 of the receiving cavity 23, as well as the dimensions of the protrusion 24 and the groove 1321 in the extending direction, can be uniformly configured such that the gap value is approximately equal to the extending length of the protrusion 24, and uniformly configured such that the charging gun head 13, in such a way as Figures 2-4 When the plane is rotated downwards by 5°-20°, the top surface 1312 of the charging gun head 13 comes into contact with the inner wall of the receiving cavity 23, and the protrusion 24 and the groove 1321 disengage at the same time.

[0065] Other structures of the charging gun 10 and the charging gun holder 21 may also have some preferred configurations. For example, the outer diameter of the charging gun rod 12 is smaller than the outer diameter of the gun head end 132, and the charging gun head 13 smoothly transitions to the charging gun rod 12 via a transition section 1311. Correspondingly, the bottom inner surface of the first section 231 is provided with a slope 2311 near the opening 22, and the slope 2311 is configured to extend inward and downward from the opening 22. The cooperation of the slope 2311 and the transition section 1311 forms a stepped structure, which further prevents the charging gun head 13 from dislodging from the receiving cavity 23.

[0066] In addition to the groove and protrusion structures, the limiting part may also have other structures. For example, the limiting part may be a plane that applies downward pressure to the charging gun head. It should be noted that such a plane that can apply downward pressure (i.e., apply pressure perpendicular to the first direction) should also be understood as a mechanism that extends perpendicular to the first direction.

[0067] This utility model also provides a charging pile and a charging system having the charging gun holder, the charging system including the charging pile and the charging gun. The above description of the embodiments of the charging gun and charging gun holder should also be understood as a description of the embodiments of the charging pile and the charging system.

[0068] This utility model's charging gun holder allows the charging gun to be supported on the charging gun holder solely through engagement with its limiting part. The full and stable engagement between the charging gun and the limiting part is achieved based on the gravity combined with the lever principle of the charging gun rod. When the user needs to install or remove the charging gun, they only need to rotate the charging gun to engage it with or remove it from the charging gun holder. The charging gun holder eliminates the need for a conventional locking / releasing button, reduces the step of pressing the hanging button, and eliminates the conventional pulling and unhooking actions, thus improving user convenience.

[0069] The above description of various embodiments of this utility model is provided for descriptive purposes to a person skilled in the art. It is not intended to exclude or limit the utility model to a single disclosed embodiment. As taught above, those skilled in the art will understand that various alternatives and variations of this utility model are possible. Therefore, although some alternative embodiments have been specifically described, those skilled in the art will understand or relatively easily develop other embodiments. This utility model is intended to include all alternatives, modifications, and variations of the utility model described herein, as well as other embodiments falling within the spirit and scope of the utility model described above.
