Description

Technical Field

[0001] This invention relates to the field of display screen technology, specifically to a mobile adaptive terminal display screen. Background Technology

[0002] With the popularity of shared bicycles and cycling, users often use their phones for navigation when riding in unfamiliar environments. Riders typically hold their phones in one hand and grip the handlebars with the other. This is because they need real-time navigation on their phones to find their route, and the hand holding the phone cannot easily grip the handlebars. When encountering unexpected road conditions, riders using this posture are more prone to collisions due to insufficient time to avoid obstacles, or falls caused by the bicycle's instability due to emergency maneuvers.

[0003] Based on the above problems, existing solutions address the need for mobile phone navigation while cycling by using bicycle phone holders, such as the handlebar phone holder disclosed in application number CN201610195675.5. However, since bicycle phone holders are typically located on the bicycle handlebars, and the distance between them and the rider's eyes is usually around 300 to 400 mm, the rider needs to concentrate on observing the navigation information on the phone. Furthermore, because the rider's gaze is focused on the phone screen while observing the information, they may not be able to notice unexpected situations in time, which could lead to traffic accidents and poses a significant safety hazard.

[0004] To address this, a mobile-adaptive terminal display screen is proposed. Summary of the Invention

[0035] Figures 1 to 10 This illustrates a first embodiment of a mobile-adaptive terminal display screen according to an exemplary description of the present invention.

[0036] A mobile adapter terminal display screen includes a display screen 1, a headband mechanism, and a connector; the display screen 1 is a liquid crystal display screen 1, which is covered with a shell made of polyphenylene sulfide material; the headband mechanism includes a ring assembly 2 and a rotating assembly 3; the ring assembly 2 has a ring-shaped cross-section and is used to fix the connector and the display screen 1 to the user's forehead by wearing it on the user's head; the rotating assembly 3 is disposed inside the ring assembly 2 and is used to adjust the position of the display screen 1 on the ring assembly 2.

[0037] With the popularization of shared bicycles and cycling, cyclists unfamiliar with the routes need to use one hand to hold a mobile phone for route navigation and the other hand to hold the handlebars to control the direction of the ride. When faced with some unexpected road situations, cyclists are more prone to accidents because they only have one hand to control the bicycle.

[0038] To address this issue, existing bicycle phone holders are typically located on the handlebars, at a distance of 300-400mm from the rider's eyes. Under these conditions, riders need to concentrate on observing navigation information on their phones. Because the rider's gaze is fixed on the phone screen, they cannot promptly observe these unexpected situations, which can lead to traffic accidents and poses a significant safety hazard.

[0039] Therefore, the ring assembly 2 in the headband mechanism uses a connector to fit the display screen 1 onto the rider's head, so that the display screen 1 is located on the side of the rider's eyes; the rider only needs to use peripheral vision or rotate his eyes to observe the specific content on the display screen 1 while riding; the rider can also adjust the display screen 1 to the other side of the headband mechanism by rotating the assembly 3 according to his own eye habits and road conditions.

[0040] Since the distance between the display screen 1 and the human eye is kept at 50-100mm, even nearsighted cyclists will not feel strained when looking at the display screen 1. And since the cyclist's line of sight when looking at the display screen 1 is consistent with the line of sight when looking at the road while riding, the display screen 1 will not prevent the cyclist from being unable to observe the road conditions in time and thus prevent accidents. This improves the safety and convenience of cyclists.

[0041] The connector has an L-shaped structure and is used to fix the display screen 1 to the head ring mechanism. The connector includes a housing 4, a distance adjustment component, and an angle adjustment component. The connector at one end of the housing 4 is fixedly connected to the head ring mechanism. The other end of the housing 4 is fixedly connected to the angle adjustment component. The distance adjustment component is used to adjust the distance between the display screen 1 and the head ring mechanism. The angle adjustment component is fixedly connected to the display screen 1 and is used to adjust the angle between the display screen 1 and the ring assembly 2.

[0042] Since each cyclist's viewing distance is different, it is necessary to adjust the distance between the display screen 1 and the cyclist's eyes. After the cyclist puts the invention on his head, the distance between the display screen 1 and his eyes is adjusted by controlling the distance adjustment component, and the angle between the display screen 1 and his eyes is adjusted by the angle adjustment component.

[0043] Reference Figure 1-2 In a preferred embodiment of the present invention, in order to enable the present invention to fit snugly with the cyclist's protective helmet, the sidewall of the ring assembly 2 is fixedly fitted with nylon Velcro. When the cyclist wears the helmet, he only needs to attach the nylon Velcro on the sidewall to the inner wall of the helmet to complete the fit. This increases the application scenarios of the present invention and improves its convenience.

[0044] Reference Figure 1-2 In a preferred embodiment of the present invention, to ensure that cyclists can clearly observe the information on the display screen 1 outdoors, a baffle is arranged in a circular array around the display screen 1. The baffle is made of opaque carbon fiber plate. Since cyclists mostly ride outdoors, in sunny weather, the glass screen of the mobile phone can easily refract sunlight, making it difficult for cyclists to clearly observe the navigation information on the mobile phone. With this embodiment, most of the sunlight can be blocked by the baffle, so that cyclists can easily observe the content on the display screen 1. This improves the efficiency and stability of the present invention.

[0045] As a preferred embodiment of the present invention, since cyclists mostly ride outdoors, they can only rely on mobile power sources to replenish their power during the ride; therefore, the present invention is inconvenient to use outdoors. In order to increase the usage time and improve the efficiency of the present invention, a solar panel is provided on the back of the display screen 1; the solar panel is electrically connected to a battery disposed inside the casing of the display screen 1; the battery is an aluminum battery with a sheet structure.

[0047] In use, simply stretch the front forehead protector 21 and the rear protector 23 apart, and then put the ring assembly 2 on the user's forehead. At this time, the elastic band will make the front forehead protector 21 and the rear protector 23 fit tightly against the user's head due to the elasticity. The dustproof cotton set on the inner wall of the ring assembly 2 can prevent the ring assembly 2 from directly contacting the user's skin, and prevent the invention from falling off due to sweat on the user's head after wearing it for a long time, as well as the discomfort caused by the marks. The dustproof cotton can also prevent wind and sand from entering the interior of the invention during cycling, thus improving the service life of the invention and the user experience.

[0048] Reference Figure 3-6 In a preferred embodiment of the present invention, in order to adjust the display position of the display screen 1, the present invention is provided with a rotating component 3, which includes a rotating shaft 31, a knob 32, a limiting plate 33, a sleeve rod 34, a bevel gear 35, an anti-slip disc 36, an elastic element 37, a rack 38 and a fixing block 39. All of the above components are made of lightweight polyphenylene sulfide material.

[0051] The elastic element 37 deforms when pressed and contracted; the elastic element 37 is sleeved on the rotating shaft 31; the elastic element 37 is located between the positioning hole and the bevel gear 35; the elastic element 37 can be a spring or other elastic component.

[0052] The rack 38 has a semi-ring structure; the cross-section of the rack 38 is triangular; the rack 38 is installed inside the front headband 21 along its length; the rack 38 meshes with the bevel gear 35; a fixing block 39 is fixedly installed at one end of the rack 38.

[0053] If the position of display screen 1 cannot be adjusted, when the user is riding on different sides of the road, the screen may block part of the view on the side where the vehicle is traveling, resulting in a blind spot for the rider and making it impossible to see the vehicle behind in time. Therefore, it is necessary to be able to adjust the position of display screen 1 to adjust the blind spot, so that the rider can turn display screen 1 to the other side of the vehicle's direction while riding, thereby avoiding traffic accidents.

[0054] In the above embodiment, when the user needs to adjust the position of the display screen 1, the knob 32 is pressed; at this time, the knob 32 drives the rotating shaft 31 to slide along the central axis, thus driving the sleeve 34 to slide; the sleeve 34 drives the anti-slip disc 36 and the bevel gear 35 to slide, thereby the anti-slip disc 36 disengages from the inner wall of the front forehead protector 21, and the bevel gear 35 meshes with the rack 38; at this time, the knob 32 can be rotated, and with the help of the rotation of the bevel gear 35, the rack 38 slides along the length direction of the front forehead protector 21; thus, the fixing block 39 slides under the drive of the rack 38; through the above embodiment, the present invention has better convenience and efficiency of use.

[0055] In a preferred embodiment of the present invention, in order to allow the display screen 1 to be removed for maintenance and cleaning when not in use, a pin hole 391 is provided in the middle of the fixing block 39; the connector is fixedly connected to the pin hole 391 on the rotating component 3 by means of a pin; when the screen needs to be removed for maintenance, cleaning and repair, it is only necessary to pull the pin out of the pin hole 391; and after the repair is completed, inserting the pin into the pin hole 391 can fix the display screen 1 to the head cover mechanism; thereby improving the ease of use and service life of the present invention.

[0056] Reference Figure 7-8 In a preferred embodiment of the present invention, to avoid the display screen 1 being too close or too far from the rider, thus making it impossible to clearly observe the information content on the display screen 1, the housing 4 in the above embodiment is provided with sliding grooves 41 symmetrically on both sides; the distance adjustment component includes a push rod 51, a locking tooth 52, a support rod 53 and a sliding bar 54;

[0057] The push rod 51 is coaxially and slidably installed inside the housing 4; the locking teeth 52, support rod 53, and sliding bar 54 are symmetrically arranged on the left and right sides of the push rod 51; one end of the push rod 51 is fixedly connected to the angle adjustment assembly; multiple springs are arranged in an array along the length direction on one side of the locking teeth 52; the locking teeth 52 are fixedly connected to the push rod 51 through the springs; the support rod 53 is symmetrically arranged on the left and right sides of the locking teeth 52; the support rod 53 is fixedly connected to the tooth side on the other side of the locking teeth 52; the support rod 53 slides in the sliding groove 41; the sliding bar 54 is located outside the housing 4; the sliding bar 54 is fixedly connected to the support rod 53.

[0058] When the user presses the sliding strips 54 on both sides of the housing 4, the internal springs deform; at the same time, the sliding strips 54 drive the locking teeth 52 to slide inward through the support rod 53; at this time, the toothed side of the locking teeth 52 disengages from the inner wall of the housing 4, and then the user needs to push the sliding strips 54 to slide along the sliding groove 41, so that the locking teeth 52 can push the push rod 51 to slide along the length direction of the housing 4, thereby pushing the display screen 1 fixed on the angle adjustment component to slide; thereby adjusting the distance between the display screen 1 and the user's eyes, improving the ease of use of the present invention.

[0059] Reference Figure 9-10 In a preferred embodiment of the present invention, to solve the problem of adjusting the angle of the display screen 1, the angle adjustment component includes a torque shaft 61 and a torsion block 62. One end of the torque shaft 61 is vertically fixedly connected to the moving end of the push rod 51. The torsion block 62 has a rectangular structure, with its top rotatably connected to the other end of the torque shaft 61, and its sidewall is fixedly connected to the display screen 1 through a buffer 621. Due to the propagation characteristics of light, if the angle of the display screen 1 is not adjusted, the user will have difficulty seeing the content information on the display screen 1 during the rotation of the display screen 1, especially when the angle between the normal of the display screen 1 and the user's center line is 50-70 degrees. This improves the ease of use of the present invention.
