[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "disposed" should be understood in a broad sense. For example, they may refer to fixed connection or disposition, detachable connection or disposition, or integral connection or disposition. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "several" means two or more, unless otherwise specifically defined.

[0022] like Figure 1-3 As shown, a two-way electronic lock for automobile accessories includes: a left shell 1, a lower shell 2, an upper shell 3, a motor 4, a lock rod 5, a transmission wheel 1 6, a transmission wheel 2 7, a worm 8 and a compression spring 10. The motor 4 is provided with a plug interface 11 for plugging and transmitting current. The worm 8 is interference-fitted at the output end of the motor 4. A mounting cavity is provided between the upper shell 2 and the lower shell 3. The motor 4 and the worm 8 are mounted in the mounting cavity. The worm 8 is used to adjust the output direction of the motor 4 and increase the transmission ratio to reduce the size of the electronic lock and increase the pushing force of the lock rod 5. By inputting current into the motor 4, the worm 8 drives the transmission wheel 6, and at the same time the transmission wheel 6 drives the transmission wheel 27 to achieve the unlocking of the lock rod 5.

[0023] Two metal sheets 12 are fixedly connected in the installation cavity of the lower shell 2, and two metal needles are installed at the plug interface 11, and the metal sheets 12 are in contact with the metal needles. The metal needles and the metal sheets 12 are made of the same material and are used to transmit current to the motor 4 after contacting each other.

[0024] Two locking rods 5 are provided and are symmetrically installed in the lower shell 2 and the upper shell 3 respectively, and are unlocked by moving outward. The upper shell 3 is clamped on the lower shell 2, and the left shell 1 is clamped on the lower shell 2 and the upper shell 3. Through holes are opened on the right sides of the left shell 1 and the lower shell 2 and the upper shell 3, respectively, for the two locking rods 5 to extend outward.

[0025] The compression spring 10 is sleeved on the outer wall of the lock rod 5, and the two ends of the compression spring 10 are respectively connected to the lock rod 5, the left shell 1, and the inner walls of the lower shell 2 and the upper shell 3, for providing the ability to reset the lock rod 5 after the electronic lock is activated.

[0026] A fixed column is fixedly connected to the lower housing 2, and transmission wheel 1 (6) is movably sleeved on the outer wall of the fixed column. A gear cavity is provided in the left outer housing 1, and transmission wheel 2 (7) is mounted in the gear cavity via a rotating shaft. Transmission wheel 1 (6) is provided with worm gear grooves and spur gear grooves. Transmission wheel 2 (7) is provided with spur gear grooves. Transmission wheel 1 (6) is connected to worm 8 via the worm gear grooves, and transmission wheel 2 (7) is connected to transmission wheel 1 (6) via the spur gear grooves. Driven by worm 8, transmission wheel 1 (6) and transmission wheel 2 (7) are driven simultaneously, and cooperate with locking rod 5 to convert torque into bidirectional thrust for locking rod 5, achieving the purpose of bidirectional unlocking. At the same time, the worm gear groove on transmission wheel 1 (6) cooperates with worm 8 to transmit the torque. Worm 8 is designed not to be self-locking. Once the input shaft stops rotating within a set time, the compression spring 10 pushes the locking rod 5 to reset.

[0027] The outer walls of the two locking rods 5 are respectively covered with rubber rings 9 to reduce noise and vibration when the locking rods 5 move. The transmission wheel 1 6 and the transmission wheel 2 7 are provided with card slots, which respectively abut against the two locking rods 5 to push the locking rods 5 to move. Among them, the locking rods 5 have installation positions, which can be directly installed with structures such as glove box lock rods. Compared with the traditional electric glove box lock structure, this component integrates the return mechanism with the electronic lock, which greatly reduces the installation space and production cost.

[0028] The working principle of this utility model is as follows:

[0029] Motor 4 is connected to the motor control board via a metal pin. The motor control board controls the on / off circuit of motor 4. When powered on, motor 4 rotates, driving worm 8 on its shaft, which in turn drives transmission wheel 1 6. Because transmission wheel 1 6 meshes with transmission wheel 2 7, synchronous drive is achieved. The slots in transmission wheels 1 6 and 2 7 tilt the locking lever 5, causing it to move linearly, unlocking the lock. A compression spring 10 is also mounted on the locking lever 5, forcing it toward the center, resetting it.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
