Description

A ratchet swing arm mechanism for rotating and braking a retractable charging cable

Technical Field

The utility model relates to the technical field of charging cables, in particular to a rotation braking mechanism or device for a telescopic charging cable.

Background Art

The method of designing a storage cable for a charger needs to be designed separately for each charger or power product, which is very troublesome from the perspective of production and use. People often need to use power devices when traveling. The existing charging cables are easy to bend when stored, which can easily damage the metal conductor in the charging cable and reduce the service life. In addition, the charging cables that are not organized are messy and inconvenient to store and carry.

Therefore, people have designed double-pull and single-pull retractable charging cables. Regardless of whether it is a double-pull or single-pull retractable charging cable, the charging cable needs to be automatically retracted into a storage box for easy storage and carrying. When it is used next time, it is only necessary to pull out the charging cable. In this way, this retractable charging cable must have a mechanism or device for rotation braking to control the positioning and stability of the pulling out and automatic rotation retraction of the charging cable. The utility model provides a mechanism for rotation braking for this retractable charging cable to achieve the function of controlling the positioning and stability of the pulling out and automatic rotation retraction of the charging cable.

DETAILED DESCRIPTION

The present invention is described in detail, clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

1 , the utility model discloses a ratchet swing arm mechanism for rotating and braking a telescopic charging cable, comprising: a swing arm body 1, a shaft hole 2 is provided at the rear end of the swing arm body 1, the shaft hole 2 is rotatably sleeved on a fixed shaft 3, the shaft 3 can be fixed to the inner side of the protective shell of the telescopic charging cable, and is integrally injection molded with the shell, or can be fixed to the middle partition inside the shell of the telescopic charging cable, and is integrally injection molded with the partition. In short, the fixing of the shaft 3 belongs to conventional technical means in the field, which will not be repeated here. A brake finger 4 is provided at the front end of the swing arm body 1, and a swing arm shaft 5 is provided at the front end of the swing arm body 1 behind the brake finger 4; a ratchet body 6, the ratchet body 6 has a ratchet shaft hole 7, the ratchet shaft hole 7 is rotatably sleeved on the swing arm shaft 5, the ratchet body 6 has evenly arranged ratchet teeth 8, and brake baffles 9 and empty tooth spaces 10 are spaced between the ratchet teeth 8; two brake columns 11, the two brake columns 11 are symmetrically fixedly arranged On the left and right sides of the swing arm body 1, the two brake columns 11 can also be fixed to the inner side of the protective shell of the telescopic charging cable, and can be integrally injection molded with the shell, or fixed to the middle partition inside the telescopic charging cable shell, and can be integrally injection molded with the partition. In short, the fixing of the two brake columns 11 also belongs to the conventional technical means in this field, and will not be repeated here. When the ratchet body 6 rotates, the swing arm body 1 swings to the left or right. At this time, one of the two brake columns 11 can be stuck in the interior of the empty tooth space 10, or it can support the brake baffle 9; a spring clip 12, the left and right ends 13 of the spring clip 12 are fixedly arranged, and similarly, the left and right ends 13 can be fixed to the inner side of the protective shell of the telescopic charging cable, or fixed to the middle partition inside the telescopic charging cable shell. In short, the fixing of the left and right ends 13 of the spring clip 12 also belongs to the conventional technical means in this field, and will not be repeated here. The middle part 14 of the spring clip 12 contacts the tail 15 of the swing arm body 1.

In a preferred embodiment, the two brake columns 11 are both triangular columns, which can better cut into the empty tooth space 10 or support the brake baffle 9 to achieve the two functions of allowing rotation or braking positioning.

In a preferred embodiment, the left and right ends 13 of the spring piece 12 are respectively fixed to a fixing frame 16, and the fixing frame 16 can also be fixed to the inner side of the protective shell of the telescopic charging cable and be integrally injection molded with the shell, or can be fixed to the middle partition inside the shell of the telescopic charging cable and be integrally injection molded with the partition. In short, the fixing of the fixing frame 16 also belongs to conventional technical means in this field and will not be described in detail here. In this embodiment, the left and right ends 13 of the spring piece 12 have a bend 17, and the bend 17 is clamped on the fixing frame 16 respectively.

The working principle of the utility model is as follows: the middle part 14 of the spring sheet 12 contacts the tail part 15 of the swing arm body 1, so that the spring sheet 12 generates an elastic compressive force on the tail part 15 of the swing arm body 1, and at the same time, the brake finger 4 elastically contacts the outer circumference of the rotating disk of the charging cable (not shown in the figure). When the charging cable is stretched out or automatically retracted, the rotating disk of the charging cable (not shown in the figure) rotates to the left or right, and drives the swing arm body 1 to swing to the left or right, thereby driving the ratchet body 6 to swing to the left or right. When an empty tooth space 10 of the ratchet body 6 is stuck in one of the two brake posts 11, the swing amplitude of the swing arm body 1 is increased. The braking finger 4 is in elastic contact with the outer circumferential surface of the rotating disk of the charging cable (not shown in the figure), the rotating disk of the charging cable can be rotated, and the charging cable can be stretched out or automatically retracted. When a braking baffle 9 of the ratchet body 6 presses against one of the two braking columns 11, the swing amplitude of the swing arm body 1 becomes smaller, and the braking finger 4 is inserted into the bayonet groove of the rotating disk of the charging cable (not shown in the figure, and the rotating disk of the charging cable is not described in detail in the utility model), and the rotating disk of the charging cable cannot rotate, thereby realizing the rotation braking of the rotating disk of the charging cable by the braking finger 4, so as to realize the positioning function of controlling the stretching out or automatic rotation and retraction of the charging cable.

Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
