Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and in particular to an external forklift fingerprint recognition installation and protection device. Background Technology

[0002] In the field of forklift safety management, traditional methods such as passwords, IC cards, or mechanical keys suffer from problems such as easy loss, easy misuse, and cumbersome operation, making it difficult to effectively guarantee the uniqueness and security of operation permissions. Introducing fingerprint recognition technology can improve the reliability of identity verification. However, the forklift operating environment is relatively harsh, often accompanied by severe vibration, oil and dust, drastic temperature and humidity changes, and physical impact. The installation structure of fingerprint recognition in the consumer electronics field lacks dedicated protection for industrial environments. It is prone to sensor damage, recognition failure, or decreased accuracy due to the above factors, and cannot meet the long-term, stable, and highly secure operation permission management requirements of forklifts. There is an urgent need for a fingerprint recognition installation protection structure designed for the special working conditions of forklifts. To this end, an external forklift fingerprint recognition installation protection device has been designed. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to propose an external forklift fingerprint recognition installation protection device that effectively reduces the impact of environmental factors (dirt, vibration, displacement) on the fingerprint sensor, ensuring the stability and accuracy of the fingerprint recognition process and improving the reliability of the identity authentication system.

[0004] According to the present invention, an external forklift fingerprint recognition installation protection device includes a forklift top guard and a fingerprint lock, wherein the surface of the forklift top guard is fixed with a protective device.

[0005] The protective device includes a pad, a mounting plate is welded and fixed to one side of the pad, a protective cover is welded and fixed to the side of the pad, and an assembly plate is welded to the side of the pad, located inside the protective cover and perpendicular to the protective cover. The surface of the assembly plate is provided with assembly holes.

[0006] Preferably, the fingerprint lock includes a control box and a fingerprint recognition head, and the fingerprint lock and the fingerprint recognition head are electrically connected via a plug-in connection.

[0007] Preferably, the control box is installed inside the forklift hood and electrically connected to the forklift equipment, and the fingerprint recognition head is fixed in the mounting hole of the assembly plate.

[0008] Preferably, the mounting plate has an L-shaped structure, and mounting holes are provided on the surface of the mounting plate, with the spacing between the mounting holes set to 30mm.

[0009] Preferably, the protective cover has an inverted U-shaped structure with its opening facing downwards.

[0010] Preferably, the assembly plate has an L-shaped structure.

[0011] The beneficial effects of this utility model are:

[0012] 1. The vertical welding structure of the "L"-shaped round hole mounting plate and the rear square pad plate forms a solid three-dimensional frame. Combined with the through hole for precise positioning and limiting of the fingerprint lock, it effectively resists impacts and collisions from multiple directions as well as strong vibrations in the device, preventing the fingerprint lock body from loosening and deforming.

[0013] 2. The "U"-shaped protective cover covers the key areas of the fingerprint lock (especially the sensing area) from the top and sides, forming a physical barrier that effectively blocks accidental falling objects, collisions with operating tools, human stepping, and lateral scratches, greatly reducing the risk of external mechanical damage.

[0014] 3. The overall bracket has a simple installation structure, few parts, and strong and reliable welded connections, making it easy to manufacture, assemble, and maintain;

[0015] The aforementioned protective and stabilizing measures work together to effectively reduce the impact of environmental factors (dirt, vibration, displacement) on the fingerprint sensor, ensuring the stability and accuracy of the fingerprint recognition process and improving the reliability of the identity authentication system.
