Detailed implementation manners

[0026] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made in conjunction with the accompanying drawings of the specification.

[0027] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. Embodiment 1

[0029] Refer to Figures 1 - 3, which is the first embodiment of the present invention. This embodiment provides a feedback type programmable AC charging interface circuit simulator. The feedback type programmable AC charging interface circuit simulator includes a main body component 100, which includes a body 101. On one side of the body 101, there is a socket 102. On the body 101, there are a display screen 103 and a button switch 104.

[0030] On one side of the body 101, there is a signal lamp for displaying the connection status of the body 101. Insert the charging gun on the charging pile into the socket 102 and start the body 101 through the button switch 104. Then, the body 101 can simulate the situation when an electric vehicle is connected to the charging pile. After connection, the body 101 can send AC signals to the charging pile according to the set parameters, including signals such as voltage, current, and frequency during normal charging, so as to test whether the charging pile can correctly identify and process these signals, thereby detecting whether the charging function of the charging pile is correct. This is the prior art and will not be elaborated in this solution. Those skilled in the art can clearly understand this working principle.

[0031] A protection component 200 is arranged on the body 101 and includes a shock-resistant member 201. The shock-resistant member 201 includes a protection frame 201a. The protection frame 201a is arranged on the outside of the body 101. On one side of the protection frame 201a, there is a shock-absorbing block 201b fixed, and on one side of the protection frame 201a, there is a connecting rod 201c fixed.

[0032] The number of both the protection frame 201a and the shock-absorbing block 201b is four, which are respectively located at the four corners of the body 101. The protection frame 201a is L-shaped and extends a part on both sides, wrapping the front and back of the body 101 and the corners of the body 101. On both sides of the protection frame 201a, there are connecting rods 201c fixed. By connecting and fixing the four protection frames 201a through the connecting rods 201c, the protection frame 201a can be stably connected to the body 101, avoiding the situation that the protection frame 201a will be separated from the body 101 during use.

[0033] During use, the body 101 is protected through the cooperation of the protection frame 201a and the shock-absorbing block 201b. When the body 101 falls to the ground, no matter what posture it lands in, the body 101 can be protected by the protection frame 201a, and the impact force on the body 101 can be buffered by the shock-absorbing block 201b, thereby avoiding the situation that the body 101 will be damaged when it falls.

[0034] The protection component 200 further includes a protection member 202. The protection member 202 includes a protection plate 202a. A buffer strip 202b is fixed to one side of the protection plate 202a. A positioning block 202c is fixed to one side of the protection frame 201a. A positioning column 202d is fixed to one side of the protection plate 202a. The positioning column 202d is rotatably connected to the positioning block 202c. A torsion spring 202e is sleeved on the outer side of the positioning column 202d. Two ends of the torsion spring 202e are respectively fixed to the positioning column 202d and the positioning block 202c.

[0035] A plurality of ventilation holes are formed in the protection plate 202a, which can reduce the wind resistance when the protection plate 202a rotates. There are two buffer strips 202b, which are respectively fixed to both ends of one side of the protection plate 202a. Through the cooperation of the positioning column 202d and the positioning block 202c, it is used to support and position the protection plate 202a. Through the torsion spring 202e, a torsional force is applied to the positioning column 202d and the protection plate 202a, so that the protection plate 202a can always be in a horizontal state, avoiding the situation that the protection plate 202a rotates during use and carrying.

[0036] When the body 101 accidentally falls, the positioning column 202d will drive the protection plate 202a to rotate downward, so that the protection plate 202a rotates to a horizontal state and wraps the display screen 103 inside, thereby protecting the display screen 103 and avoiding the situation that the sharp objects on the ground will damage the display screen 103 after falling to the ground. The buffer strip 202b is used to buffer the impact force received by the protection plate 202a, avoiding the situation that the protection plate 202a collides with the body 101 when being impacted. Embodiment 2

[0037] Refer to Figures 1 - 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0038] Specifically, the protection component 200 further includes a fixing member 203. The fixing member 203 includes a suction cup 203a. The suction cup 203a is fixed to one side of the body 101. A rotating handle 203b is arranged on one side of the suction cup 203a.

[0039] During use, when the body 101 is taken to the position to be detected, first fit the suction cup 203a with the smooth position on the charging pile, and press down the rotating handle 203b to make the suction cup 203a adsorb to the charging pile, thereby fixing the body 101, further avoiding the situation that the operator needs to hold the body 101 for a long time during use, which is not convenient for operating the body 101, and avoiding the situation that the body 101 is not placed stably and will fall when placed.

[0040] When it is necessary to remove the body 101, lift the rotation handle 203b upward, and the suction cup 203a can be disengaged from the charging pile.

[0041] Specifically, the protection component 200 further includes a transmission member 204. The transmission member 204 includes a gear 204a, and the gear 204a is fixed to the outside of the positioning column 202d. A positioning rod 204b is fixed to one side of the body 101. A rotating rod 204c is rotatably connected to the positioning rod 204b through a rotating shaft. A chute 204c-1 is formed at the top end of the rotating rod 204c. A rack 204d is arranged on the top of the body 101. A positioning shaft 204f is fixed to one side of the rack 204d, and the positioning shaft 204f slides in the chute 204c-1. A first spring 204g is fixed to one side of the rotating rod 204c, and the other end of the first spring 204g is fixed to the body 101. A push rod 204h is fixed to one side of the rotating rod 204c, and one side of the rotating rod 204c contacts the rotation handle 203b.

[0042] A fixed frame is fixed to the top of the protection frame 201a. The rack 204d is movably connected inside the fixed frame. The center of the rotating rod 204c is rotatably connected to the positioning rod 204b through a rotating shaft, and the rotating rod 204c is inclined.

[0043] When the suction cup 203a is not yet adsorbed and fixed to the charging pile, the rotation handle 203b limits the rotating rod 204c, so that the rotating rod 204c cannot move under the thrust of the first spring 204g. When the suction cup 203a is adsorbed and fixed to the charging pile and the rotation handle 203b rotates downward, at this time the rotation handle 203b will separate from the rotating rod 204c. At the same time, the end of the push rod 204h will contact the charging pile, and then the rotating rod 204c can be restricted by the push rod 204h so that it cannot rotate.

[0044] When the body 101 accidentally falls during use, at this time the push rod 204h separates from the charging pile, and the rotation handle 203b does not return upward normally. In this way, the bottom end of the rotating rod 204c can be pushed by the first spring 204g to move, so that the top end of the rotating rod 204c drives the rack 204d to rotate through the cooperation of the positioning shaft 204f and the chute 204c-1, and drives the gear 204a and the positioning column 202d to rotate through the rack 204d, so that the positioning column 202d drives the protection plate 202a to rotate.

[0045] The elastic force of the first spring 204g is greater than the elastic force of the torsion spring 202e.

[0046] Specifically, the protection component 200 further includes a pressing member 205. The pressing member 205 includes a pressing plate 205a. The pressing plate 205a is located above the socket 102. A fixing rod 205b is fixed to the top of the pressing plate 205a. A support plate 205c is fixed to one side of the body 101. The fixing rod 205b is movably connected within the support plate 205c. A friction strip 205e is fixed to the bottom of the pressing plate 205a.

[0047] The pressing plate 205a is arc-shaped. Through the cooperation of the fixing rod 205b and the support plate 205c, it is used to support and position the pressing plate 205a. When the body 101 drops, the pressing plate 205a will move downward and squeeze the charging gun, generating a lateral moving force on the charging gun, so that the connection between the charging gun and the socket 102 is tightened. And the friction strip 205e is used to increase the friction between the charging gun and the socket 102, further avoiding the separation of the charging gun from the socket 102, thus avoiding the damage of the socket 102 when the charging gun is forcibly separated from the socket 102 due to the dropping of the body 101.

[0048] Specifically, an installation block 205f is fixed to the top of the fixing rod 205b. A second spring 205g is fixed to the bottom of the installation block 205f. The bottom end of the second spring 205g is fixed to the support plate 205c.

[0049] The second spring 205g exerts a pulling force on the installation block 205f, and drives the fixing rod 205b and the pressing plate 205a to move downward through the installation block 205f, so that the pressing plate 205a can exert sufficient pressure on the charging gun.

[0050] Specifically, the protection component 200 further includes a locking member 206. The locking member 206 includes a plug rod 206a. A jack 205b-1 is formed on the fixing rod 205b. The plug rod 206a is engaged with the jack 205b-1. A positioning frame 206b is fixed to the top of the support plate 205c. The plug rod 206a is movably connected within the positioning frame 206b. A fixing ring 206c is fixed to the outside of the plug rod 206a. A third spring 206d is fixed to one side of the fixing ring 206c. The other end of the third spring 206d is fixed to the positioning frame 206b. The plug rod 206a is L-shaped.

[0051] The positioning frame 206b is used to support and position the plug rod 206a. When the plug rod 206a is engaged with the jack 205b-1, the fixing rod 205b can be limited through their cooperation, avoiding the downward movement of the fixing rod 205b during normal use and further avoiding the situation of blocking the socket 102.

[0052] The third spring 206d is used to exert a pushing force on the fixing ring 206c, and drives the plug rod 206a to be more tightly engaged with the jack 205b-1 through the fixing ring 206c, avoiding the separation of the two.

[0053] When the protective plate 202a rotates downward, it will contact the insertion rod 206a and push the insertion rod 206a to move, so that the insertion rod 206a can be separated from the insertion hole 205b-1, and thus the restriction on the fixing rod 205b can be released. Embodiment 3

[0054] Referring to Figures 1 - 9 , this is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0055] Specifically, a stabilizing column 203c is fixed on one side of the body 101. A stabilizing sleeve 203d is sleeved outside the stabilizing column 203c. One end of the stabilizing column 203c is fixed with a fourth spring 203e, and the other end of the fourth spring 203e is fixed to the inner wall of the stabilizing sleeve 203d.

[0056] The number of the stabilizing column 203c, the stabilizing sleeve 203d and the fourth spring 203e is four, and they are respectively located at the four corners on one side of the body 101. Through the cooperation of the three, they are used to support and position the body 101. If the fixed position of the body 101 on the charging pile is not completely horizontal, the body 101 can be kept in a horizontal state.

[0057] Specifically, a stabilizing rod 105 is fixed on one side of the body 101. One end of the stabilizing rod 105 is rotatably connected with a dust-proof cover 106 through a rotating shaft, and the dust-proof cover 106 fits with the socket 102.

[0058] The dust-proof cover 106 is used to protect the socket 102 to prevent dust from entering the inside of the socket 102 during the placement process.

[0059] Specifically, a handle 107 is fixed on one side of the body 101.

[0060] The handle 107 can facilitate the user to carry the body 101.

[0061] During use, when the body 101 is taken to the position to be detected, first, the suction cup 203a is attached to the smooth position on the charging pile, and the rotating handle 203b is pressed downward to make the suction cup 203a adsorb to the charging pile, so as to fix the body 101, thereby avoiding the situation that during the use process, the operator needs to hold the body 101 for a long time, which is not convenient for operating the body 101, and avoiding the situation that when the body 101 is placed, it is not placed stably and will fall. When the rotating handle 203b rotates downward, at this time, the rotating handle 203b will be separated from the rotating rod 204c. At the same time, the end of the ejector rod 204h will contact the charging pile, and thus the rotating rod 204c can be restricted by the ejector rod 204h so that it cannot rotate.

[0062] During the use of the body 101, if it accidentally falls, at this time, the ejector rod 204h is separated from the charging pile, and the rotating handle 203b does not return upward normally. Thus, the bottom end of the rotating rod 204c can be pushed by the first spring 204g to move, so that the top end of the rotating rod 204c drives the rack 204d to rotate through the cooperation of the positioning shaft 204f and the sliding groove 204c-1, and drives the gear 204a and the positioning column 202d to rotate through the rack 204d.

[0063] The positioning column 202d will drive the protection plate 202a to rotate downward, so that the protection plate 202a rotates to a horizontal state and wraps the display screen 103 inside. Thus, the display screen 103 can be protected to avoid the situation that the sharp objects on the ground will damage the display screen 103 after falling to the ground. The buffer strip 202b is used to buffer the impact force received by the protection plate 202a to avoid the situation that the protection plate 202a will collide with the body 101 when being impacted.

[0064] At the same time, the body 101 is protected through the cooperation of the protection frame 201a and the shock-absorbing block 201b. When the body 101 falls to the ground, no matter what posture it lands in, the body 101 can be protected by the protection frame 201a, and the impact force on the body 101 is buffered by the shock-absorbing block 201b. Thus, the situation that the body 101 will be damaged when falling can be avoided.

[0065] Meanwhile, when the protection plate 202a rotates downward, it will contact the insertion rod 206a and push the insertion rod 206a to move. Thus, the insertion rod 206a can be separated from the insertion hole 205b-1, and further the restriction on the fixed rod 205b can be released. The second spring 205g exerts a pulling force on the mounting block 205f, and drives the fixed rod 205b and the pressing plate 205a to move downward through the mounting block 205f. The charging gun is squeezed by the pressing plate 205a to generate a force for the charging gun to move horizontally. Thus, the connection between the charging gun and the socket 102 can be made tighter, and the friction between the charging gun and the socket 102 is increased through the friction strip 205e. Thus, it can be further avoided that the charging gun will be separated from the socket 102, so as to avoid the situation that the socket 102 will be damaged when the charging gun is forcibly separated from the socket 102 due to the fall of the body 101.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
