[0029] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The present embodiment relates to a knob-type quick-release mechanism suitable for screwless use, including a charging module assembly 10 and a charging pile housing assembly 20 that are detachably connected through a quick-release mechanism, the quick-release mechanism including a frame 30 connected to the charging module assembly 10 and a safety lock assembly 40 located on one side of the frame 30, the frame 30 is also movably equipped with a transmission assembly 50, the end of the transmission assembly 50 is equipped with a spring pin 60 that sequentially penetrates and connects the charging module assembly 10 and the charging pile housing assembly 20 outward, the safety lock assembly 40 and the transmission assembly 50 are dynamically connected in a locked / unlocked manner through a spring 70 and a ball 71. It should be noted that locking / unlocking specifically means that locking refers to the synchronous connection between the safety lock assembly 40 and the transmission assembly 50, and unlocking refers to the independent dynamic movement between the safety lock assembly 40 and the transmission assembly 50.

[0031] The transmission assembly 50 includes a knob 51, a connecting rod 52, and a cam 53 connected in sequence from the head end to the end end. Preferably, the knob 51, the connecting rod 52, and the cam 53 are synchronously transmitted. The knob 51 and the cam 53 are arranged parallel to each other. The connecting rod 52 is connected to the end hole of the frame 30 and dynamically cooperates in a self-rotating manner under the action of external force. In this embodiment, the external force refers to the rotational force applied to the transmission assembly 50 by the operator during the actual production process. Other force application methods are also included in this embodiment, which is hereby explained.

[0032] A cavity is formed inside the knob 51 and a spring 70 is installed in the cavity. The spring 70 is arranged in a manner of pointing from the axis of the knob 51 to the outer ring of the knob 51; a through hole 54 adapted to the size of the ball 71 is opened on the surface of the outer ring of the knob 51, and the ball 71 is connected to the end side of the spring 70 adjacent to the outer ring of the knob 51. The ball 71 is implemented in a manner of always passing through the through hole 54. Therefore, the position of the spring 70 can be defined accordingly according to the above-mentioned technical features, and the connection method of the other end of the spring 70 is not limited in this application. Those skilled in the art can adaptively select the method of connecting the spring 70 to the cavity of the knob 51.

[0033] The safety locking assembly 40 includes a safety ring 43 which is sleeved on the knob 51 and arranged coaxially. A ball well 44 which is adapted to the through hole 54 is provided on the inner wall of the safety ring 43. Therefore, when the ball well 44 and the through hole 54 are correspondingly connected, the ball 71 passes through the through hole 54 and abuts against the ball well 44. It should be noted that, at this time, the safety locking assembly 40 and the transmission assembly 50 are in a locked state. It can be understood that, when the safety locking assembly 40 and the transmission assembly 50 are in an unlocked state, the ball well 44 and the through hole 54 do not correspond. It should be noted that the pit edge of the ball well 44 is specifically a smooth structure.

[0034] Based on the above technical features, the spring 70, the ball 71, the ball well 44, and the through hole 54 correspond to each other in groups, and the number of groups can be multiple. Those skilled in the art can set it according to actual needs. When the number of groups is multiple, the mutual spacing positions can be adaptively opened, which is hereby explained.

[0035] The safety locking assembly 40 also includes an auxiliary fixing frame 41 bolted to the charging module assembly 10, and a safety lever limiting hole 42 is provided on the auxiliary fixing frame 41. Based on the above technical features, a safety lever 45 extending into the safety lever limiting hole 42 is processed on the outer surface of the safety ring 43. It should be noted that the safety lever limiting hole 42 is a through hole, and the operator can move the safety lever 45 extending into the safety lever limiting hole 42.

[0036] The spring pin 60 includes an adaptor bottom 61, a return spring 62, and a lock pin head 63 which are sequentially connected from one end to the other end. The adaptor bottom 61 is adapted to the cam surface of the cam 53. In the embodiment, the return spring 62 has a rod body that is compatible with the lock pin head 63. This embodiment does not limit the specific structural model of the spring pin 60, and those skilled in the art can choose it according to actual conditions. A cutting groove is provided on the lock pin head 63, and the cutting groove is used to better connect the respective lock holes of the charging module assembly 10 and the charging pile housing assembly 20 through which it passes, thereby increasing the stability of the connection.

[0037] The working principle of this embodiment is as follows:

[0038] In the initial state, the charging module assembly 10 and the charging pile housing assembly 20 are in a connected state through the quick release mechanism. In this state, when the ball sink 44 and the through hole 54 are correspondingly connected, the ball 71 is connected through the through hole 54 and abuts against the ball sink 44, the convex part of the cam 53 is in contact with the adapter bottom 61, and the lock pin head 63

[0039] When it is necessary to remove or release the connection between the charging module assembly 10 and the charging pile housing assembly 20;

[0040] First, the safety measure is unlocked, and the safety lever 45 located in the safety lever limiting hole 42 is turned counterclockwise, so that the ball sink 44 is separated from the through hole 54. During the separation process, the inner wall of the safety ring 43 abuts against the ball 71, and the spring 70 of the ball 71 is compressed, and the safety of the safety ring 43 and the knob 51 is unlocked;

[0041] Secondly, unlock the charging module assembly 10, hold the knob 51 and rotate it clockwise, then the cam 53 rotates synchronously, at this time, the convex part of the cam 53 is disengaged from the adapter bottom 61, and the spring pin 60 retracts accordingly and exits the respective lock holes of the charging module assembly 10 and the charging pile housing assembly 20, and the unlocking of the charging module assembly 10 and the charging pile housing assembly 20 is completed;

[0042] The connection locking process is the opposite of the above.

[0043] In this way, the screwless knob-type quick-release mechanism disclosed by the utility model solves the problem of high efficiency and cost of disassembly and assembly of the charging module. During the disassembly and assembly process, no auxiliary tools such as screwdrivers are required, and the charging module can be disassembled and replaced by hand throughout the whole process, which greatly improves the disassembly and assembly efficiency and the product maintenance life. In addition, the human-machine experience is good during the disassembly and assembly process, which greatly simplifies the operation and maintenance operation process of the charging pile charging module, objectively reduces the operation and maintenance battery replacement costs of the charging pile enterprises, and improves the benefits of the charging pile enterprises.

[0044] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also fall within the protection scope of the present invention.
