Abstract

The invention discloses an electromagnetic lock switch mechanism, and particularly relates to a lock of an automobile trunk. In order to earn profit, a switch mechanism of the lock is unlocked by a plastic gear pushing and pulling lock tongue mechanism driven by a motor, and after the lock is used for 3 years, the switch is insensitive due to aging of the plastic gear. The invention uses the ingenious combination of electromagnet and neodymium-iron-boron strong magnetism to replace a motor to drive a plastic gear pulling and pushing lock tongue mechanism to unlock. The opening and closing times of the unlocking mechanism exceed one thousand times, the service life of the unlocking mechanism is matched with that of the whole automobile, resources are effectively saved, and the use timeliness of the product is improved.

Description

Electromagnetic lock switch mechanism

Technical Field

The invention relates to the field of automobile accessories, in particular to a lock of an automobile trunk.

Background

Disclosure of Invention

Aiming at the technical problems in the prior art, the invention provides a method for directly combining an electromagnet and neodymium-iron-boron strong magnetism to replace a plastic gear poking and pushing lock tongue mechanism driven by a motor to unlock, so as to solve the problems that the plastic gear is easy to age and break and the lock switch is not sensitive,

in order to achieve the technical purpose, the technical scheme of the invention is realized as follows:

the electromagnetic lock switching mechanism includes: 1. the lock comprises a lock bolt, a riveting fixing hole 2, a lock bolt switch handle 3, a lock body bracket 4, a cross countersunk head fixing bolt 5, a traction force adjusting bolt 6, a right-angle T iron 7, a strong magnet 8, a guide groove 9, a guide positioning column 10, a needle bearing 11, a traction arm 12, an electromagnetic shaft 13, a spring 14, an electromagnetic coil 15, a power supply socket 16 and an unlocking push rod 17;

the end of an electromagnetic shaft 13 and the end of a traction arm 12 are connected in series by a needle roller shaft sleeve and lubricated by base grease, when an electromagnetic coil 15 is powered on, electromagnetic force is generated 14, a spring is compressed 13, the electromagnetic shaft pulls the traction arm 12 inwards, the distance between a right-angle T iron 7 and a strong iron 8 is shortened, at the moment, the strong iron 8 attracts the right-angle T iron 7, an unlocking push rod 17 is pushed by the acting force of the electromagnet and the strong iron 8 to push a lock tongue switch handle 3, a lock tongue is opened 1 (see the attached drawing figure 2 of the specification),

when 15, the electromagnetic coil loses the electromagnetic force after the power supply is cut off, 14, the spring is extended outwards after the pressure is relieved, and simultaneously, 7, the right-angle T iron is separated from 8, the strong magnet under the action of 3, the buffer force of the bolt switch handle (see the attached drawing figure 3 in the description)

When a user closes the trunk downwards, the user is pressed by the trunk which is closed downwards 1. the spring bolt is jacked upwards by the lock ring designed on the trunk seat, so that the spring bolt 1 extends out in an arc shape to hook the lock ring designed on the trunk seat, and the trunk is locked; at this time, 3, the arc end surface of the lock tongue switch handle is just attached 17, the end surface of the unlocking push rod is prepared for the next unlocking action (see the attached figure 1 of the specification);

the invention has the beneficial effects that:

1. the invention uses the combination of electromagnet and neodymium-iron-boron strong magnetism to replace a plastic gear poking and pushing lock tongue mechanism driven by a motor to unlock. The opening and closing times of the unlocking mechanism exceed one thousand times, the service life of the unlocking mechanism is almost synchronous with that of the whole automobile, 2, the resources are effectively saved, the use time of the product is improved,

description of the drawings:

to more clearly illustrate the "electromagnetic lock switch mechanism" of the present invention, the drawings are as follows:

FIG. 1: the invention relates to a structure diagram of an electromagnetic lock switch mechanism under a lock tongue closed state;

FIG. 2: the invention relates to a structure diagram of a 'electromagnetic lock switch mechanism' in a bolt opening state;

FIG. 3: the electromagnetic lock switch mechanism completes unlocking action and is in a structure diagram after resetting;

the specific implementation mode is as follows:

the following description of the present invention, which will be made clear and complete by referring to the drawings of the specification, is based on the description of the present invention and the description of the present invention,

in the invention, 13 electromagnetic shafts and 12 ends of a traction arm are connected in series by needle roller shaft sleeves, the parts in series connection are required to rotate flexibly, the shaft sleeves and the needle roller parts are lubricated by lithium-based lubricating grease, a main body structure of the electromagnetic lock switch mechanism is assembled into a whole by 11 needle roller bearings, then the main body mechanism of the electromagnetic lock switch mechanism is fixed on 4 lock body brackets by a shaft rod, the needle roller bearings are lubricated by the lithium-based lubricating grease (see figure 1 of the attached drawing of the specification),

fixing the 6-traction force adjusting bolt on the 4-lock body bracket by using a bracket and a ten-countersunk head bolt, and fixing the 6-traction force adjusting bolt bracket, wherein the distance between the right end surface of the bracket and the right end surface of the bracket is 7, and the distance between the left end surface of the right-angle T iron is 10 mm. 6. The traction force adjusting bolt can be adjusted forwards or backwards through an inner screw hole in the middle of the fixing support to change the attraction distance between the 7 DEG T iron and the 8 DEG strong magnet, so that the intensity of the strong magnetic traction force is adjusted to achieve 17, the best effect of the thrust force when the unlocking push rod is unlocked is achieved, after the adjustment is determined to be finished, the cross screwdriver is used for screwing the screw in the middle of the traction force adjusting bolt support 6 to fix the traction force adjusting bolt 6 so that the traction force adjusting bolt cannot be loosened,

when 15, electromagnetic coil is connected with power supply to generate electromagnetic force, 14, spring is compressed, 13, electromagnetic shaft pulls 12, traction arm to shorten the distance between 7, right-angle T iron and 8, strong magnet, 8, strong magnet attracts 7, right-angle T iron, 17, unlocking push rod receives electromagnet and 8, strong magnet acting force to push 3, lock tongue switch handle to open 1, lock tongue (see attached figure 2 in description),

When a user closes the trunk downwards, the user is pressed by the trunk which is closed downwards 1. the spring bolt is jacked upwards by the lock ring designed on the trunk seat, so that the spring bolt 1 extends out in an arc shape to hook the lock ring designed on the trunk seat, and the trunk is locked; at this time, 3, the arc end surface of the bolt switch handle is just attached to 17, the end surface of the unlocking push rod is prepared for the next unlocking action (see the attached figure 1 in the specification).
