Description

Technical Field

[0001] This utility model relates to the technical field of forklift starting devices, and in particular to a forklift driver fingerprint recognition starting device. Background Technology

[0002] The background technology of fingerprint recognition start devices for forklift drivers primarily stems from the rapid development and widespread application of biometric technology. Biometric technology utilizes unique physiological or behavioral characteristics for identity verification, with fingerprint recognition, as a mature biometric identification method, gaining widespread attention due to its high accuracy and ease of use. Forklifts, as indispensable equipment in warehousing and logistics operations, are increasingly valued for improving their safety and operational efficiency.

[0003] In the daily operation of forklifts, drivers often need to frequently touch the fingerprint recognition device for identity verification. When the existing forklift driver fingerprint recognition start device is used, over time, the high-frequency use of the fingerprint recognition device causes some fingerprint residue to gradually accumulate on the surface. As a result, when multiple drivers take turns using the same forklift, the fingerprint recognition device will come into contact with multiple different fingerprint information, thereby reducing the accuracy of information recognition. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a forklift driver fingerprint recognition start device.

[0005] To solve the above-mentioned technical problems, the present invention provides a forklift driver fingerprint recognition start device, including a main body and a fingerprint contact sensor located thereon, wherein two sets of parallel data transmission interfaces are installed on the side of the main body away from the fingerprint contact sensor.

[0006] The main body is provided with an anti-fingerprint overlap mechanism located on the same side as the fingerprint contact sensor, which is used to transfer fingerprints and avoid fingerprint overlap.

[0007] The anti-fingerprint overlap mechanism is equipped with a fingerprint cleaning mechanism located on the horizontal side of the main body, which is used to clean the driver's residual fingerprints on the anti-fingerprint overlap mechanism, so as to realize the recycling of the anti-fingerprint overlap mechanism.

[0008] The present invention is further configured such that: the anti-fingerprint overlap mechanism includes a mounting box and a motor horizontally mounted thereon; the mounting box is provided with drive shafts on both sides of the fingerprint contact sensor, and one of the drive shafts is fixedly connected to the output end of the motor; a cover film covering the fingerprint contact sensor is rotatably mounted on the drive shaft; the cover film is made of polyethylene terephthalate material.

[0009] The present invention is further configured such that: a guide shaft located on the mounting box is installed between the annular edge of the fingerprint contact sensor and the transmission shaft, for guiding the bonding of the double-layer covering film.

[0010] The present invention is further configured such that: the fingerprint cleaning mechanism includes a support roller on the rotating and mounting box and a second synchronous wheel located thereon; a first synchronous wheel is provided on the transmission shaft and is on the same straight line as the second synchronous wheel; and a synchronous belt rotates between the outer wall of the second synchronous wheel and the outer wall of the first synchronous wheel.

[0011] The present invention is further configured such that the diameter of the second synchronous pulley is smaller than that of the first synchronous pulley, which is used to control the speed difference between the drive shaft and the drive shaft.

[0012] The present invention is further configured such that: multiple sets of springs with different degrees of compression are wrapped around the support roller, and a sleeve roller is fixed to the other end of the spring.

[0013] The present invention is further configured such that: a soft cloth that fits against the covering film is sleeved on the roller, and the soft cloth is a microfiber cloth.

[0014] The present invention is further configured such that: an ash outlet is provided on the side of the mounting box near the motor, which is located at a position corresponding to the diameter of the roller.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the design of an anti-fingerprint overlap mechanism and a fingerprint cleaning mechanism, can transmit and clean fingerprints using a covering film layer when different forklift drivers use the same forklift, ensuring that the fingerprint recognition sensor can always clearly recognize the forklift driver's fingerprints, avoiding fingerprint residue that could lead to incorrect recognition information, thereby greatly improving the working performance of the fingerprint recognition device.

[0017] 2. This utility model, through the design of an anti-fingerprint overlap mechanism and a fingerprint cleaning mechanism, enables the replacement of the cover film at the recognition position after fingerprint recognition, and then cleans the fingerprints on the cover film, so that the cover film can be reused while ensuring the accuracy of the forklift driver fingerprint recognition device.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0024] Please see Figures 1-4 A forklift driver fingerprint recognition start device includes a main body 11 and a fingerprint contact sensor 12 located thereon. Two sets of parallel data transmission interfaces 13 are installed on the side of the main body 11 away from the fingerprint contact sensor 12. An anti-fingerprint overlap mechanism 2 is provided on the main body 11 on the same side as the fingerprint contact sensor 12 to transmit fingerprints and avoid fingerprint overlap. A fingerprint cleaning mechanism 3 is installed on the anti-fingerprint overlap mechanism 2 on the lateral side of the main body 11 to clean the driver's residual fingerprints on the anti-fingerprint overlap mechanism 2, so as to realize the cyclic use of the anti-fingerprint overlap mechanism 2. In use, the forklift start device is connected to the forklift main controller through the data transmission interface 13 in the prior art. Then, the driver touches the fingerprint contact sensor 12, the fingerprint contact sensor 12 collects the image and converts it into an electrical signal, which is processed by the microcontroller and sent to the main controller. The main controller compares the data with the pre-stored authorized fingerprint data. If the verification matches, the main controller triggers the start relay and connects the starter motor circuit to start the forklift.

[0025] like Figure 3 As shown, the anti-fingerprint overlap mechanism 2 includes a mounting box 25 and a motor 21 horizontally mounted thereon. The mounting box 25 is provided with drive shafts 22 on both sides of the fingerprint contact sensor 12, and one of the drive shafts 22 is fixedly connected to the output end of the motor 21. A cover film 24 covering the fingerprint contact sensor 12 rotates on the drive shaft 22. The cover film 24 is made of polyethylene terephthalate. A guide shaft 23 located on the mounting box 25 is installed between the annular edge of the fingerprint contact sensor 12 and the drive shaft 22 to guide the double-layer cover film 24 to adhere.

[0026] After the forklift driver starts the forklift, the anti-fingerprint overlap mechanism 2 will transfer and replace the driver's fingerprint. Specifically, the starter motor 21 drives the cover film 24 on the drive shaft 22 to rotate. As a result, the fingerprint will move away from the fingerprint contact sensor 12 as the drive shaft 22 rotates. Then, the cover film 24 in the blank area will move to the fingerprint contact sensor 12, waiting for the next fingerprint recognition to start, thus ensuring the accuracy of fingerprint recognition.

[0027] It is important to understand that the guide shaft 23 can not only drive the cover film 24, but also bring the double-layer cover film 24 in the transmission state closer together, ensuring that the distance is small when the cover film 24 is double-layered, which is convenient for accurate fingerprint recognition. In addition, the material of the cover film 24 has excellent light transmittance and a smooth surface, which will not interfere with the fingerprint recognition module's collection of fingerprint texture.

[0028] like Figure 4 As shown, the fingerprint cleaning mechanism 3 includes a rotating support roller 34 on the mounting box 25 and a second synchronous wheel 32 located thereon. A first synchronous wheel 31 is provided on the drive shaft 22, which is on the same straight line as the second synchronous wheel 32. A synchronous belt 33 rotates on the outer wall of the second synchronous wheel 32 and the first synchronous wheel 31. The diameter of the second synchronous wheel 32 is smaller than that of the first synchronous wheel 31, which is used to control the speed difference between the drive shaft 22 and the drive shaft 22. Multiple sets of springs 35 with different degrees of compression are wrapped around the support roller 34, and a sleeve roller 36 is fixed to the other end of the spring 35. A soft cloth 37 that fits against the covering film 24 is sleeved on the sleeve roller 36, and the soft cloth 37 is made of microfiber cloth. A ash outlet 38 is opened on the mounting box 25 near the motor 21, which is located at the position corresponding to the diameter of the sleeve roller 36.

[0029] When the cover film 24 is replaced, the fingerprint cleaning mechanism 3 is used to clean the fingerprints remaining on the cover film 24. Specifically, as the drive shaft 22 rotates, it drives the first synchronous wheel 31 to rotate. Under the connection of the synchronous belt 33, it drives the soft cloth 37 on the support roller 34 connected to the second synchronous wheel 32 to rotate. Due to the diameter difference between the second synchronous wheel 32 and the first synchronous wheel 31, the same position on the cover film 24 can be rotated multiple times by the soft cloth 37, ensuring the cleanliness of the cover film 24.

[0030] At the same time, as the drive shaft 22 rotates, when the cover film 24 is attached to the soft cloth 37, the spring 35 between the support roller 34 and the sleeve roller 36 will be squeezed. When the soft cloth 37 rotates away from the cover film 24, the spring 35 will restore its elastic potential energy. Through repeated rapid compression and rotation, the soft cloth 37 will vibrate, which will facilitate the removal of residual fingerprints and dust after cleaning to the ash outlet 38. Thus, the anti-fingerprint overlap and cleaning operation of the forklift driver fingerprint recognition device is completed.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
