Description

Technical Field

[0001] The utility model belongs to the technical field of automobile equipment, and in particular relates to a near-end locking mechanism for an automobile charging port cover. Background Art

[0002] Since the 20th century, cars have become people's main means of transportation. At present, the automobile industry has become an important driving force for my country's economic development and has a great role in promoting the development of the national economy. With the development of society, the use of new energy vehicles such as electric vehicles and hybrid vehicles is becoming more and more common, and the charging port cover on new energy vehicles is an important component of the vehicle, used to replace the fuel filler cap of fuel vehicles. At present, actuators are generally used on the market to start doors, compartments, etc. to achieve automatic opening and closing.

[0003] The existing automatic charging port cover is mainly composed of a motor and a motion mechanism. The charging port cover is opened or closed by the motor. However, when in the closed state, due to the limitation of the motor torque, the charging port cover cannot have sufficient holding force, which will result in the charging port cover product being unable to be locked in the closed state, resulting in an abnormal gap between the charging port cover and the vehicle body. What's worse, the failure to lock will cause the charging port cover to be thrown out due to inertia during vehicle driving, or when the vehicle turns at high speed, the charging port cover is at risk of being thrown out by centrifugal force.

[0004] At the same time, in order to increase the competitiveness of their products, some new energy brand car companies have added a reverse charging function, that is, adding a socket for other electrical equipment to the side of the charging station. However, if the charging port cover cannot be locked when closed, there is a risk that the reverse charging function will be used by others. In order to solve the problem of being unable to lock, the current common solution is to add an electronic lock. The principle is that after the charging port cover is closed, a signal is given through the in-place switch, and the electronic lock starts to work after receiving the signal to lock the charging port cover. However, the cost of electronic locks is relatively high, and it will also increase the difficulty of the vehicle control logic. Utility Model Content

[0027] The utility model proposes a near-end locking mechanism for a car charging port cover. In order to make the purpose, technical solution and advantages of the utility model clearer, the following is combined with the attached Figure 1-Figure 5 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] A near-end locking mechanism for a car charging port cover includes a gear box 1 and a gear set arranged in the gear box, wherein the gear set includes a driving shaft 3, an output shaft 4 and a locking pin rod 5 respectively arranged on one side of the driving shaft 3. The output shaft 4 is connected to an opening and closing assembly, and the driving shaft 3 drives the output shaft 4 to rotate when working, drives the opening and closing unit to open and close, and drives the locking pin rod 5 to lock and unlock the opening and closing assembly.

[0029] One end of the driving shaft 3 is connected to the driving mechanism through a spline 32; a driving gear is arranged on the driving shaft 3. The driving mechanism is a motor, which is arranged on both sides of the gear box with the driving shaft respectively. The spline 32 of the driving shaft 3 passes through the gear hole 11 of the gear box 1 and is connected to the motor on the other side. When the motor works, it will drive the driving shaft 3 to rotate. The driving gear is an incomplete gear. The driving gear is meshed with the output shaft.

[0030] The output shaft 4 includes a shaft 41 and an output gear 42 disposed on the shaft 41, and the output gear 42 is meshed with the driving gear. Similarly, the output gear 42 is an incomplete gear. One end of the shaft 41 is connected to the opening and closing unit; in this embodiment, the opening and closing unit includes a charging door and a connecting rod 2 disposed on the charging door, and the shaft 41 is connected to the connecting rod 2.

[0031] Specifically, the driving gear includes first driving gear teeth 31 evenly distributed on a part of the circumference, and the other side of the circumference is a smooth surface 333, on which second driving gear teeth 334 are arranged, and two second driving gears 334 are arranged.

[0032] The gear teeth of the output gear 42 include first gear teeth 422 evenly arranged locally around the circumference and a second gear tooth 421 arranged adjacent to the first gear tooth 422. The second gear 421 is provided with one. The gap between the second gear tooth 421 and the adjacent first gear tooth 422 is greater than the gap between each adjacent first gear tooth 422.

[0033] The lock pin rod 5 is arranged on the other side of the output shaft 4, and includes a pin rod 51 and a pin rod plate 53 arranged in the middle of the pin rod 51. A pin hole 52 is opened at one end of the pin rod 51, and the lock pin rod 5 is inserted into the gear box 1 through the pin rod 51. A return spring 62 is arranged between the gear box 1 and the pin rod plate 53, and is connected to the cable assembly arranged on the other side of the gear box 1 through the pin hole 52. The cable assembly includes a pull rope 6, one end 61 of the pull rope is connected to the pin hole 52, and the other end is provided with a pull ring 63 for easy pulling. One end of the pin rod plate 53 cooperates with the driving shaft, and the other end of the pin rod plate 53 is fixed to the pin rod 51.

[0034] Furthermore, a lock pin driving member is provided at the other end of the driving shaft 3, and the lock rod plate 53 is connected to the lock pin driving member. When the driving shaft works, the lock pin rod 5 is driven to reciprocate along the axial direction of the pin rod 51. In this embodiment, a lock hole is provided on the connecting rod, and one end of the pin rod 51 reciprocates in the lock hole, that is, when the lock pin rod 5 reciprocates along the axial direction of the pin rod 51, one end of the pin rod 51 will reciprocate in the lock hole, thereby realizing unlocking or locking of the connecting rod.

[0035] The lock pin driving member is a step wheel 33 placed on the driving shaft, and a first step surface 331 is provided on the step wheel 33. A guardrail is partially surrounded by the first step surface 331. An arc-shaped transition is formed between one end 3321 of the guardrail and the first step surface 331 to form an upper step 332. The step surface of the upper step 332 is arranged below the uniform gear teeth of the driving gear.

[0036] A step opening 531 is provided at one end of the pin plate 53 , and the pin plate 53 is mounted on the step wheel through the step opening 531 .

[0037] In order to better understand the present invention, the following uses the charging door as an example to explain the process of opening and closing, unlocking, locking, etc. of the charging door according to the present invention.

[0038] In normal state, the motor works, driving the driving shaft 3 to rotate, the driving shaft 3 drives the output shaft 4 to rotate, the pin plate 53 transitions between the first step surface 331 and the upper step 332, so that the pin 51 will be away from the lock hole on the connecting rod to unlock, and when the driving shaft continues to rotate, the charging door on the connecting rod is driven to open. Otherwise, it is closed and locked.

[0039] When the driving motor fails, the utility model can perform emergency wire unlocking by pulling the rope.

[0040] When the charging door connecting rod is in the closed position, the return spring 62 keeps the locking pin rod in the locked position (i.e., the pin rod is in the connecting rod lock hole). When there is no power input to the driving shaft, when external force input attempts to drive the output shaft and the door connecting rod to move, the locking of the pin rod will prevent the door connecting rod from rotating, thereby preventing the door from being opened.

[0041] At this time, if the pull rope 6 is pulled by external force, the pull rope 6 will drive the pin rod 51 of the lock pin rod to leave the lock hole of the connecting rod. At this time, the external force input can drive the output shaft to finally drive the small door to open.

[0042] Finally, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
