Description

Technical Field

[0001] The utility model relates to the technical field of engineering vehicles, in particular to a transmission structure for remote-control unlocking. Background Art

[0002] Engineering vehicles are the backbone of a construction project. Their appearance has doubled the progress of the construction project and greatly reduced manpower.

[0003] Currently, car handles can realize the remote unlocking function, but the working nature of engineering vehicles is different from that of cars. Their handles may need to withstand greater force and impact. Therefore, their load-bearing capacity and durability must be considered during design. That is, most engineering vehicle handles are fixed with screws. In this case, only traditional mechanical keys can be used to unlock the car, which reduces the convenience of use to a certain extent.

[0004] Therefore, a transmission structure for remote-control unlocking is proposed. Utility Model Content

[0005] In view of this, the embodiments of the present utility model hope to provide a transmission structure for remote control unlocking to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] A motor is installed on one side of the second housing, and a second gear is installed on the output shaft of the motor;

[0008] The outer side of the push rod is sleeved with a first gear, and the second gear is meshedly connected with the first gear.

[0009] In some embodiments: a signal exchanger is installed on one side of the second shell, and an electrical output end of the signal exchanger is electrically connected to an electrical input end of the motor.

[0011] In some embodiments, the outer cross-section of the arc-shaped portion matches the outer cross-section of the limiting block.

[0012] In some embodiments: the first shell is mounted on the second shell.

[0013] In some embodiments: a limiting portion is provided on the outer side of the push rod, and a limiting groove matched with the limiting portion is provided on the second shell.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] After the remote control device (external environment) completes signal interaction with the signal communicator, the utility model starts the motor, the output shaft of the motor drives the second gear to rotate, the second gear transmits the first gear, and the first gear drives the push rod to rotate until the limiting part on the outside of the push rod is aligned with the limiting groove, and the push rod can be pushed to complete unlocking.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood based on the description and drawings combined with specific circumstances.

[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-7 As shown, the embodiment of the utility model provides a transmission structure for remote unlocking, including a second housing 2, on which a rotatable push rod 7 is mounted:

[0031] A motor 51 is installed on one side of the second housing 2, and a second gear 5 is installed on the output shaft of the motor 51;

[0032] The outer side of the push rod 7 is sleeved with the first gear 4 , and the second gear 5 is meshingly connected with the first gear 4 .

[0033] In this embodiment, specifically: a signal exchanger 3 is installed on one side of the second housing 2, and an electrical output end of the signal exchanger 3 is electrically connected to an electrical input end of the motor 51;

[0034] More specifically, the signal interactor 3 is any one of a serial port converter, a network switch or a wireless signal transceiver, preferably a wireless signal transceiver, which is used to send and receive wireless signals, such as devices in wireless communication technologies such as Wi-Fi, Bluetooth, Zigbee, etc., that is, in actual use, any signal interactor 3 that can complete signal interaction to start and stop the drive motor 51, and rotate forward or reverse can be used.

[0035] In this embodiment, specifically: a rotation groove 41 is opened on the top of the first gear 4, a limiting block 83 is fixedly connected to the inner side of the rotation groove 41, a rotatable rotating part 81 is arranged inside the rotation groove 41, and an arc-shaped part 82 is integrally formed on the outer side of the rotating part 81.

[0036] More specifically: the outer cross-section of the arc-shaped portion 82 is consistent with the outer cross-section of the limit block 83. When the first gear 4 drives the limit block 83 to rotate, the limit block 83 can rotate in the blank area between the arc-shaped portion 82 and the rotating groove 41. Under the clutch mechanism 8 composed of the rotating portion 81, the arc-shaped portion 82 and the limit block 83, electronic remote control unlocking can be achieved.

[0037] In this embodiment, specifically: the first housing 1 is installed on the second housing 2, the first housing 1 and the second housing 2 form the appearance of the handle, the lock core housing is installed on the first housing 1, and provides a precondition for the installation of the lock core. The lock core is used for mechanical key unlocking, the lock core is fixedly connected to the rotating part 81, the outer side of the push rod 7 is provided with a limiting part 71, and the second housing 2 is provided with a limiting groove 6 adapted to the limiting part 71. The mechanical key unlocking steps include:

[0038] Insert the mechanical key into the lock core and turn the mechanical key. The lock core drives the rotating part 81 to rotate, and the rotating part 81 drives the arc-shaped part 82 to rotate. When the side of the arc-shaped part 82 touches the side of the limit block 83, the first gear 4 can be driven to rotate together. When the first gear 4 rotates, it drives the push rod 7 to rotate until the limit part 71 on the outside of the push rod 7 is aligned with the limit groove 6. Then the push rod 7 can be pushed to complete the unlocking.

[0039] When the utility model is working: after completing the signal interaction with the signal communicator 3 through the remote control device (external environment), the motor 51 is started, the output shaft of the motor 51 drives the second gear 5 to rotate, the second gear 5 transmits the first gear 4, and the first gear 4 drives the push rod 7 to rotate until the limiting portion 71 on the outside of the push rod 7 is aligned with the limiting groove 6, the push rod 7 can be pushed to complete the unlocking, and the remote control unlocking can be realized in a limited space. While ensuring the carrying capacity and durability of the engineering vehicle handle, the convenience of use is improved.

[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
