[0002] Due to vision problems, blind people often need to carefully feel for the location of the fingerprint recognition module when using traditional fingerprint locks, which brings certain inconveniences to the blind. Therefore, we designed a lock handle specifically for the blind. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides a special lock handle for the blind. The special lock handle for the blind is provided with a first finger group and a second finger group so that when the blind person holds his hand on the handle base, his thumb is just located at the second finger group, and the other four fingers are just located at the second finger group. At the same time, the fingerprint recognition module in the second finger group is used to perform fingerprint recognition and unlocking through the thumb. The setting of the first finger group and the second finger group provides a convenient positioning basis for the blind person's operation, which is convenient for the blind person to use.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides a lock handle for the blind, comprising a handle base connected to the lock and a fingerprint recognition module, wherein the handle base is provided with a first finger group and a second finger group, wherein the first finger group is 4 arc-shaped depressions opened on the handle base, and the second finger group is 1 arc-shaped depression arranged below the first finger group, and the 5 depressions of the first finger group and the second finger group are arranged in the shape of a person's fingers holding the handle;

[0006] The fingerprint identification module is arranged in the second finger group and is arranged in a direction away from the first finger group.

[0007] The utility model discloses a special lock handle for the blind, which adopts an ergonomically designed first finger group and a second finger group. When the blind person holds the lock, the handle can be naturally guided to position so that the thumb of the blind person is located at the first finger group. The thumb can directly perform fingerprint recognition and unlocking through the fingerprint recognition module, which is fast and safe. At the same time, compared with the design in which the fingerprint recognition module faces upward or outward, since the thumb faces upward when held, the fingerprint recognition module of the utility model faces downward, and with the protection of the structure of the second finger group itself, the fingerprint recognition module itself is not easily damaged.

[0008] The utility model provides a special lock handle for the blind by setting a first finger group and a second finger group, so that when the blind hold their hands on the handle base, their thumbs are just located at the second finger group, and the other four fingers are just located at the second finger group. At the same time, the fingerprint recognition module in the second finger group is used to perform fingerprint recognition and unlocking through the thumb. The setting of the first finger group and the second finger group provides a convenient positioning basis for the operation of the blind, and is easy for the blind to use.

[0009] In a further technical solution, the handle base is in the shape of a strip, and the first finger group and the second finger group are respectively arranged on opposite sides of the handle base.

[0010] The strip-shaped handle base has the widest application range, and its structure itself is particularly suitable for holding, and users have the best usage habits.

[0011] In a further technical solution, the opening of the arc-shaped recess of the second finger group opens toward both sides.

[0012] The opening of the second finger group is opened, that is, the depression of the second finger group can guide the operation direction of the thumb during blind touch, further facilitating the operation of the blind.

[0013] In a further technical solution, the handle base is circular in shape, the first finger group is recessed inward from the outer circular surface of the handle base, and the second finger group is recessed on the disc surface of the handle base in a direction parallel to its axial direction.

[0014] The advantage of a round handle base is that it is easy to touch and find, has smooth edges, is highly safe, and is also suitable for blind people.

[0015] In a further technical solution, the depression of the second finger group is trumpet-shaped.

[0016] The second finger group with a trumpet-shaped depression can guide the direction of the thumb during blind touch, further facilitating operation for the blind.

[0017] In a further technical solution, the handle base is provided with protective pads at the first finger group and the second finger group.

[0018] The protective pad itself can protect the hands of the blind. In addition, the material of the protective pad is different from that of the handle base. Its existence itself also indicates the position of the first finger group and the second finger group, further improving the user experience of the blind.

[0019] The beneficial effects are:
