Description

Neck-to-cervical conversion device

technical field

The invention relates to a neck-to-neck conversion device.

Background technique

Electric wheelchairs seldom have health-care neck rests, let alone neck braces. It is common to use the neck support as an accessory of a wheelchair, but when the patient is in the acute attack stage of cervical spondylosis, or when the cervical spine is stabilized and recovered after dislocation and reset, the neck support alone is not enough. To control the movement angle of the cervical spine, a neck support, neck support, etc. are needed. The support can fix the cervical spine and has a certain traction effect. In the prior art, there is no device that can be used as a neck rest or as a neck brace.

Contents of the invention

The object of the present invention is to provide a neck rest and neck support conversion device, which can realize the conversion between the neck support and the neck support, so that the neck support can also be used as a neck support at the same time.

The technical scheme that realizes the object of the present invention:

A neck support conversion device, the outer side of the neck support (18) is fixed to the back of the chair, characterized in that: the inner side of the neck support (18) is provided with a neck support (12), and the two sides of the neck support (12) are respectively provided with a set of driving mechanism, which can drive the neck collar (12) to move relative to the neck rest (18), and each group of driving mechanisms includes front and rear driving mechanisms, left and right driving mechanisms and rotating driving mechanisms;

Said rotary drive mechanism comprises motor A (13), and the output shaft of motor A (13) is fixed with the end of neck bracket (12), and motor A (13) is fixed on the support connecting plate (7);

Said front and rear driving mechanism comprises motor B (16), the first ball screw pair (3) driven by motor B (16), the nut of the first ball screw pair (3) and the first support body (2) Fixed, the first support body (2) is vertically connected and fixed with the support connecting plate (7);

Said left and right driving mechanism comprises motor C (5), the second ball screw pair (17) driven by motor C (5), the nut of the second ball screw pair (17) and the second support body (1) fixed, the second support body (1) is fixed with the first bearing seat (4) of the first ball screw pair (3), the second ball screw pair (17) is installed on the first bearing seat (10), and the second A bearing seat (10) is fixed on the bearing frame (6), and the bearing frame (6) is fixed with the chair back.

The shape and size of the neck collar (12) are identical with the shape and size of the inner side of the neck (18).

The upper edges of the neck support (12) and the neck support (18) are maxillary profiling lines, and the lower edges of the neck support (12) and the neck support (18) are chest profiling lines.

Neck support (12), neck by (18) are all made of plastics.

Said chair back can be the electric wheelchair chair back.

The beneficial effect that the present invention has:

The inner side of the neck rest of the present invention is provided with a neck support, and a group of driving mechanisms are respectively provided on both sides of the neck support. The rotation movement realizes the conversion between the neck support and the neck support, so that the neck support can also be used as a neck support at the same time. The structure design of the invention is reasonable and practical, and is easy to operate. The upper edge of the neck collar and the neck rest of the present invention is a maxillary profiling line, and the lower edge of the neck collar and the neck rest is a chest profiling line, which further increases the stability and comfort of the neck collar and the neck rest.

Detailed ways

As shown in FIG. 1 , the outer side of the neck rest 18 is fixed to the chair back 19 , and the inner side of the neck rest 18 is provided with a neck bracket 12 . The shape and size of the neck support 12 are the same as those of the inner side of the neck support 18. When the neck support is used, the neck support 12 is also a part of the neck support. As shown in Figure 2, the upper edges of the neck collar and the neck rest form the maxillary profiling line, and the lower edges of the neck collar and the neck rest form the chest profiling line. Neck support 12, neck by 18 are all made of plastics, and said chair back 19 is the electric wheelchair chair back.

Both sides of the neck support 12 are respectively provided with a group of driving mechanisms, which can drive the movement of the neck support 12 relative to the neck support 18, so as to realize the conversion between the neck support and the neck support. Each group of driving mechanisms includes a front and rear driving mechanism, a left and right driving mechanism and a rotating driving mechanism. Figure 1 shows a schematic diagram of a group of driving mechanisms.

Said rotary driving mechanism comprises motor A13, and the output shaft of motor A13 is fixed by the end of key 11 and neck bracket 12, and motor A13 is fixed on the support connecting plate 7;

Said front and rear driving mechanism comprises motor B16, motor B16 drives the first ball screw pair 3 through gears 15,14, the nut of the first ball screw pair 3 is fixed with the first support body 2, the first support body 2 and the support Connecting plate 7 is vertically connected and fixed;

Said left and right driving mechanism comprises motor C5, motor C5 drives the second ball screw pair 17 through gear 8,9, the nut of the second ball screw pair 17 is fixed with the second support body 1, and the second support body 1 is connected with the second support body 1. The bearing seat 4 of a ball screw pair 3 is fixed, and the second ball screw pair 17 is installed on the first bearing seat 10, and the first bearing seat 10 is fixed on the bearing frame 6, and the bearing frame 6 is fixed with the back of the chair.

When used as a neck support, as shown in Figure 1, the outer side of the neck support 12 is completely consistent with the inner side of the neck support 18, forming a neck support as a whole. When it is necessary to convert the neck support into a neck support, first, the front and rear drive mechanisms work, the motor B16 is energized, the gears 15 and 14 mesh, the first ball screw pair 3 works, and drives the first bracket body 2 to move forward. The body 2 drives the motor A13 and the neck support 12 to move forward through the support connecting plate 7, and completes the separation of the neck support 12 and the neck rest 18. Then, the left and right driving mechanisms work, the motor C5 is energized, the gear 8 and the gear 9 are meshed, and the second ball screw pair 17 is driven to rotate, and the second bracket body 1 drives the first bracket body 2, the first ball screw pair 3, The support connecting plate 7 and the neck collar 12 move to the left together. Then the rotary drive mechanism works, the motor A13 works, and the key 11 drives the neck collar 12 to rotate 180°, as shown in Figure 3 . Then, the motor C5 is energized and rotates in the opposite direction, and the second support body 1 drives the first support body 2, the first ball screw pair 3, the support connecting plate 7, and the neck bracket 12 to move to the right together. Finally, the motor B16 is energized, the first ball screw pair 3 works, and the neck bracket 12 is dragged by the first support body 2 to move backward until reaching a predetermined position. All the aforementioned actions are realized by controlling the corresponding motors through the computer program.
