[0002] With the widespread and rapid development of transportation in my country, mobility scooters have gradually become commonplace in countless households. The requirements for mobility scooter seats are also increasing. The handlebars of existing mobility scooter seats can be rotated and retracted, allowing drivers to easily get in and out of the seat and remain seated while driving. In actual use, due to differences in driver size, different drivers have different requirements for the height of the seat handlebars. This requires that the seat handlebars be adjustable to accommodate different drivers. Therefore, there is an urgent need to provide a mobility scooter seat with adjustable handlebar height. To this end, the present utility model provides a mobility scooter seat with convenient handlebar adjustment. Summary of the Invention

[0003] In response to the above-mentioned technical deficiencies, the purpose of the present invention is to provide a mobility scooter seat with convenient handlebar adjustment. By slidingly installing a control component in a vertical slide groove, the handle can slide up and down along the vertical slide groove and be stably fixed at a corresponding height; thereby solving the technical problems raised in the background technology.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The utility model provides a scooter seat with convenient handlebar adjustment, comprising a seat plate and two pillars symmetrically mounted on the rear side of the seat plate and used to set handlebars; a vertical slide groove extending longitudinally and having a T-shaped cross section is formed on the pillars; the vertical slide groove comprises a first wide section groove and a first narrow section groove;

[0006] A control assembly is provided between the rear end of the handle and the pillar, and the control assembly includes a T-shaped connecting block slidably installed in a vertical slide groove; the T-shaped connecting block includes a first wide portion located in the first wide section groove, a first narrow portion located in the first narrow section groove, and the front end of the first narrow portion is used to install the handle; a T-shaped slide groove is provided on the T-shaped connecting block, and a T-shaped slider that can elastically extend and retract forward and backward is slidably installed in the T-shaped slide groove, the T-shaped slide groove includes a second wide section groove provided on the first wide section, and a second narrow section groove provided on the first narrow section; the T-shaped slider includes a second wide section groove located in the second wide section groove, and a second narrow section groove located in the second narrow section groove;

[0007] The front side surface of the second wide portion is symmetrically provided with a plurality of teeth A spaced apart in the longitudinal direction. The second wide section groove penetrates the front side surface of the first wide portion so that the teeth A are exposed in the first wide section groove of the vertical slide. The side wall of the first wide section groove facing the teeth A is provided with a tooth groove matching the teeth A. A driving member is mounted on the first narrow portion of the T-shaped connecting block.

[0008] The handle has a lifting adjustment state and a locking state. When the handle is in the locking state, the tooth A is engaged with the tooth groove A. When the handle is switched to the lifting adjustment state, the driving member can drive the T-shaped slider to elastically extend and retract back and forth in the T-shaped slide groove, so that the tooth A is separated from the tooth groove A.

[0009] Preferably, a vertical sliding hole connected to the T-shaped sliding groove is provided on the first narrow part of the T-shaped connecting block; the driving member is a driving block that slides vertically and matches in the vertical sliding hole; the upper end of the driving block is exposed, and the lower end of the driving block is provided with a wedge surface A, and the second narrow part of the T-shaped slider is provided with a wedge surface B matching the wedge surface A; the driving block slides downward to drive the teeth A on the T-shaped slider to separate from the tooth groove; the lifting and lowering control process of the handle is simplified to a simple process of pressing the driving block, the design is sophisticated, and it is easy to operate.

[0010] Preferably, the front-to-back width of the second wide section groove of the T-shaped connecting block is larger than the front-to-back width of the second wide portion of the T-shaped slider, so that an activity space is formed between the second wide portion and the rear side wall of the second wide section groove, and a first compression spring acting on the second wide portion along the front-to-back direction is provided in the activity space; the first compression spring can cause the T-shaped slider to reset after the handle slides into place, so that the tooth A engages with the tooth groove and locks the position of the handle, so that the handle can support the user's arm.

[0011] Preferably, it also includes an elastic component acting on the driving block. When the driving block slides downward under the action of external force, the elastic component deforms and stores elastic force. When the external force is removed, the elastic component releases the elastic force, causing the driving block to reset upward; this facilitates the next height adjustment of the handle, and has better operability.

[0012] Preferably, the two side walls of the vertical sliding hole are symmetrically provided with limiting grooves; the two side walls of the driving block are symmetrically provided with limiting blocks, and the limiting blocks are slidably matched and installed in the limiting grooves; the elastic component is a second compression spring arranged between the lower part of the limiting block and the bottom of the limiting groove.

[0013] Preferably, the rear end of the handle is rotatably connected to the front end of the first narrow part of the T-shaped connecting block, and the rear end of the handle and the front end of the first narrow part are provided with a rotation adjustment mechanism, which can control the handle to rotate up and down and stop at the corresponding position; so that the handle can be rotated to the corresponding angle and adapt to the different tilt angles of the user's arm, further improving comfort.

The rotation adjustment mechanism includes a rotation adjustment member and an adjustment structure. The adjustment structure includes a snap-fit structure, a sliding groove extending forward and backward is opened on the first narrow portion, and the horizontal axis is passed through the sliding groove; the snap-fit structure includes a plurality of teeth B uniformly distributed along the circumference at the front end of the first narrow portion, and a plurality of tooth grooves matching the teeth B uniformly distributed along the circumference at the rear end of the handle. The rotation adjustment member is a third compression spring arranged in the sliding groove and directly or indirectly acting on the horizontal axis; in the initial state, the third compression spring acts on the horizontal axis and causes the teeth B to engage with the tooth groove, at which time the handle remains locked; external force acts on the handle, causing the horizontal axis to slide back and forth in the sliding groove and causing the third compression spring to compress, at which time the teeth B are separated from the tooth groove, so that the handle can be rotated up and down.

[0015] Preferably, a sleeve is matched in the sliding groove, the transverse axis is passed through the sleeve and can rotate axially in the sleeve, and the third compression spring is pressed between the sleeve and the corresponding side wall of the sliding groove, so that the third compression spring indirectly acts on the transverse axis; the sleeve can separate the transverse axis from the third compression spring, and when the transverse axis rotates with the handle, the sleeve can effectively avoid the third compression spring and the transverse axis from generating a large friction force, which affects the user experience.

[0016] Preferably, the cross-sectional shape of the sliding groove is square, and the outer contour cross-sectional shape of the sleeve matches the cross-sectional shape of the sliding groove; the sleeve with a square outer contour has a flat side wall surface, which can increase the contact surface between the third compression spring and the sleeve, so that the elastic force generated by the third compression spring can act more smoothly and indirectly on the horizontal axis.

[0017] Preferably, the front end of the first narrow portion has a semi-arc convex surface, and a plurality of teeth B are evenly distributed on the semi-arc convex surface along the circumferential direction. The rear end of the handle has a semi-arc concave surface, and a plurality of tooth grooves matching the teeth B are evenly distributed on the semi-arc concave surface along the circumferential direction, so that the adjustment angle of the handle is between 0-180°; when the handle is adjusted to 0°-180°, it can adapt to the user's arm angle. When the handle is adjusted to 0° or 180°, the handle remains parallel to the backrest of the mobility chair, which can save the space it occupies and facilitate storage; through the design of the semi-arc concave surface and the semi-arc convex surface, the adjustment angle of the handle is within a reasonable range, thereby improving the practicality of the mobility chair.

[0018] The beneficial effects of the present invention are:

[0019] The utility model provides a vertical slide groove with a T-shaped cross-section on the two pillars of the mobility chair, and realizes the control and adjustment of the handle height by means of two nested T-shaped parts, namely a T-shaped connecting block slidably connected in the vertical slide groove and a T-shaped slider elastically extending and retracting in the T-shaped slide groove forward and backward; when the handle is in a locked state, the teeth A of the T-shaped slider engage with the tooth groove A of the vertical slide groove, so that the handle remains fixed in the longitudinal direction; when the longitudinal position of the handle needs to be adjusted, it is only necessary to drive the T-shaped slider to elastically extend and retract forward and backward by the driving part to separate the teeth A from the tooth groove A, so that the handle can slide up and down to adjust the height; the handle can be raised and adjusted and kept in place at a corresponding height, and is suitable for occupants of different body shapes.

[0020] By setting a rotation adjustment mechanism between the rear end of the handle and the T-shaped connecting block, the handle can rotate circumferentially and stay in the corresponding position to adapt to the user's arm angle, forming a more comprehensive and comfortable support effect for the user's arm, and improving the user experience of the mobility chair.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1-9 As shown, this embodiment provides a scooter seat with convenient handlebar adjustment, comprising a seat plate 1 and two pillars 2 symmetrically mounted on the rear side of the seat plate 1 and used to provide handlebars 3; the pillars 2 are provided with a vertical slide 21 extending longitudinally and having a T-shaped cross-section; the vertical slide 21 includes a first wide section groove 21a and a first narrow section groove 21b; the first wide section groove 21a and the first narrow section groove 21b are interconnected, and the first narrow section groove 21b is in communication with the outside;

[0034] A control assembly is provided between the rear end of the handle 3 and the pillar 2, and the control assembly includes a T-shaped connecting block 41 slidably installed in the vertical slide 21; the T-shaped connecting block 41 includes a first wide portion 41a located in the first wide section groove 21a, and a first narrow portion 41b located in the first narrow section groove 21b, and the front end of the first narrow portion 41b is used to install the handle 3; a T-shaped slide 411 is provided on the T-shaped connecting block 41, and a T-shaped slider 42 that can elastically extend and retract forward and backward is slidably installed in the T-shaped slide 411, and the two T-shaped blocks form a nested structure; the T-shaped slide 411 includes a second wide section groove 41c provided on the first wide section 41a, and a second narrow section groove 41d provided on the first narrow section 41b. The T-shaped slider 42 includes a second wide portion 42a located within the second wide groove 41c and a second narrow portion 42b located within the second narrow groove 41d. A plurality of teeth A421 spaced longitudinally are symmetrically arranged on the front side of the second wide portion 42a. The teeth A on both sides are located at positions on both sides where the second wide portion 42a and the second narrow portion 42b are not connected. The second wide groove 41c passes through the front side of the first wide portion 41a, exposing the teeth A421 within the first wide groove 21a of the vertical slide 21. A tooth groove A211 matching the teeth A421 is provided on the side wall of the first wide groove 21a facing the teeth A421. A driving member is mounted on the first narrow portion 41b of the T-shaped connecting block 41.

[0035] The handle 3 has a lifting and adjusting state and a locking state. When the handle 3 is in the locking state, the teeth A421 engage with the tooth groove A211, so that the handle 3 remains in place at the corresponding height. When the handle 3 is switched to the lifting and adjusting state, the driving member can drive the T-shaped slider 42 to elastically expand and contract back and forth in the T-shaped slide groove 411, so that the teeth A421 are separated from the tooth groove A211; so that the handle 3 can be driven by the T-shaped connecting block 41 to slide longitudinally and adjust the support height. When adjusted into place, the T-shaped slider 42 can be elastically reset, so that the teeth A421 engages with the tooth groove A211 again, so that the handle 3 is switched to the locking state again.

[0036] Further, if Figure 4-6 As shown, the driving member needs to be easy for the user to operate. Therefore, in this embodiment, a vertical sliding hole 412 connected to the T-shaped sliding groove 411 is provided on the first narrow portion 41b of the T-shaped connecting block 41; the driving member is a driving block 5 that slides vertically and matches in the vertical sliding hole 412; the upper end of the driving block 5 is exposed, and the lower end of the driving block 5 is provided with a wedge surface A51, and the second narrow portion 42b of the T-shaped slider 42 is provided with a wedge surface B422 that matches the wedge surface A51; the driving block 5 slides downward to drive the teeth A421 on the T-shaped slider 42 to separate from the tooth groove A211, thereby simplifying the lifting and lowering control process of the handle 3 to a simple process of pressing the driving block 5, which is a sophisticated design.

[0037] Further, if Figure 8-9 As shown, the elastic expansion and contraction of the T-shaped slider 42 in the T-shaped slide groove 411 is achieved as follows: the front-to-back width of the second wide section groove 41c of the T-shaped connecting block 41 is greater than the front-to-back width of the second wide portion 42a of the T-shaped slider 42, so that an activity space is formed between the second wide portion 42a and the rear side wall of the second wide section groove 41c, and a first compression spring 43 is provided in the activity space, which acts on the second wide portion 42a along the front-to-back direction; the first compression spring 43 can cause the T-shaped slider 42 to reset after the handle 3 slides into place, so that the tooth A421 engages with the tooth groove A211 and locks the position of the handle 3, so that the handle 3 can support the user's arm.

[0038] Further, if Figure 5-6 As shown, in order to facilitate the reset of the driving block 5, an elastic component acting on the driving block 5 is also provided on the T-shaped connecting block 41. When the driving block 5 slides downward under the action of an external force, the elastic component is deformed and stores elastic force. When the external force is removed, the elastic component releases the elastic force, causing the driving block 5 to reset upward; this is convenient for the next height adjustment of the handle 3, and the operability is better; specifically, the two side walls of the vertical sliding hole 412 are symmetrically provided with limiting slots 413, and the upper and lower ends of the limiting slots 413 are not connected to the outside world. Limit blocks 53 are symmetrically provided on the two side walls of the driving block 5, and the limit blocks 53 are slidably matched and installed in the limiting slots 413; the elastic component is a second compression spring 52 arranged between the lower part of the limit block 53 and the bottom of the limit slot 413. The second compression spring 52 can produce elastic deformation after the driving block 5 is subjected to force, and provide a reset elastic force for the driving block 5.

[0039] Further, if Figure 4-7As shown, in this embodiment, in order to cater to the angle of the arm during use, the rear end of the handle 3 is rotatably connected to the front end of the first narrow part 41b of the T-shaped connecting block 41, and the rear end of the handle 3 and the front end of the first narrow part 41b are provided with a rotation adjustment mechanism, which can control the handle 3 to rotate up and down and stop at the corresponding position; so that the handle 3 can be rotated to the corresponding angle and adapt to the different tilt angles of the user's arm, further improving the comfort; specifically, the rear end of the handle 3 has two side parts extending backward, and a notch 31 is formed between the two sides; the front end of the first narrow part 41b is in the notch 31 between the two sides, and is rotatably connected by a horizontal shaft 611 connected between the two sides, and the horizontal shaft 611 is detachably connected to the two sides; the rotation adjustment mechanism includes a rotation adjustment member and an adjustment structure, and the adjustment structure includes a snap-fit structure, a first A sliding groove 414 extending forward and backward is provided on the narrow portion 41b, and the sliding groove 414 extends laterally inward from the side wall of the first narrow portion 41b, and the transverse axis 611 is passed through the sliding groove 414; the locking structure includes a plurality of teeth B415 uniformly distributed along the circumference at the front end of the first narrow portion 41b, and a plurality of tooth grooves B311 matching the teeth B415 uniformly distributed along the circumference at the rear end of the handle 3, and the rotation adjustment member is a third compression spring 62 arranged in the sliding groove 414 and directly or indirectly acting on the transverse axis 611; in the initial state, the third compression spring 62 acts on the transverse axis and causes the teeth B415 to engage with the tooth grooves B311, at which time the handle 3 remains locked; external force acts on the handle 3, causing the transverse axis 611 to slide forward and backward in the sliding groove 414, and causing the third compression spring 62 to be compressed, at which time the teeth B415 are separated from the tooth grooves B311, so that the handle 3 can rotate freely.

[0040] Further, if Figure 3 As shown, in this embodiment, the third compression spring 62 can be in direct contact with the transverse shaft 611 to directly act on the transverse shaft 61, or it can be in indirect contact, and the effect of indirect contact is better. Specifically, the transverse shaft 61 will rotate with the rotation of the handle 3, and the third compression spring 62 directly acts on the transverse shaft 611 to generate friction. Therefore, a sleeve 61 is matched in the sliding groove 414, and the transverse shaft 611 is passed through the sleeve 61 and can rotate axially in the sleeve 61. The third compression spring 62 is against between the sleeve 61 and the corresponding side wall of the sliding groove 414, so that the third compression spring 62 indirectly acts on the transverse shaft 611. At the same time, the sleeve 61 can separate the transverse shaft 611 from the third compression spring 62. When the transverse shaft 611 rotates with the handle 3, the sleeve 61 can effectively prevent the third compression spring 62 from generating a large friction with the transverse shaft 611, affecting the user experience.

[0041] Further, if Figure 5-7As shown, the horizontal axis 61 will rotate with the rotation of the handle 3, so the horizontal axis 61 is a cylindrical axis, but the outer wall of the cylindrical axis is an arc surface, and the contact formed between it and the third compression spring 62 is a point contact. The cross-sectional shape of the sliding groove 414 is square, and the outer contour cross-sectional shape of the sleeve 61 matches the cross-sectional shape of the sliding groove 414; the sleeve 61 with a square outer contour has a flat side wall surface, which can increase the contact surface between the third compression spring 62 and the sleeve 61, so that the elastic force generated by the third compression spring 62 can act more smoothly and indirectly on the horizontal axis 611.

[0042] Furthermore, in order to provide a better user experience of the mobility chair, the front end of the first narrow portion 41b has a semi-arc convex surface, and a plurality of teeth B415 are evenly distributed on the semi-arc convex surface along the circumference. The rear end of the handle 3 has a semi-arc concave surface, and a plurality of tooth grooves B311 matching the teeth B415 are evenly distributed on the semi-arc concave surface along the circumference, so that the adjustment angle of the handle 3 is between 0-180°; when the handle 3 is adjusted to 0°-180°, it can adapt to the user's arm angle. When the handle 3 is adjusted to 0° or 180°, the handle 3 remains parallel to the backrest of the mobility chair, which can save the space it occupies and facilitate storage; by respectively providing the tooth grooves B311 and the teeth B415 on the semi-arc concave surface and the semi-arc convex surface, the adjustment angle of the handle 3 is within a reasonable range, thereby improving the practicality of the mobility chair.

[0043] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
