Description

Technical Field

[0001] This utility model relates to the technical field of instrument devices for transportation vehicles, and in particular to a transportation vehicle and an adjustable-angle instrument device. Background Technology

[0002] Some electric two-wheelers on the market have instruments that are permanently fixed with bolts and cannot be adjusted. As a result, due to external factors such as different outdoor light intensity and different heights, the instruments cannot be adjusted to the best viewing angle according to the usage environment, thus making it impossible to efficiently and intuitively view the instrument display content and affecting the visualization effect.

[0003] To address the aforementioned issues, Chinese utility model patent CN216332482U discloses a fixing structure for an instrument panel of an electric-assisted bicycle, comprising a rotating component, an instrument panel cover, and a bearing. The rotating component has a first rotating connection portion at its upper end, and the instrument panel cover has a second rotating connection portion on its side. The first and second rotating connection portions are connected by a bearing, forming an L-shaped structure with side connection, allowing the instrument panel cover to rotate up and down relative to the rotating component with the bearing axis as the rotation center. Furthermore, the patent specification [paragraph 0022] also indicates that the bearing connection hole inner wall of the first and second rotating connection portions 1-3 has a mating surface 12, and the outer wall of the bearing has a mating surface 11. During assembly, the bearing and the bearing connection hole achieve a surface mating connection through the mating surface 11 and the mating surface 12.

[0004] Therefore, it can be seen that the instrument and the rotating part in the above patent are only connected by surface fit, and the stability of the connection between the two is low. During the user's ride, the instrument panel will be affected by wind resistance, which will cause the instrument panel to rotate and deviate from the set tilt angle, causing inconvenience to the user. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides an adjustable angle instrument device with a simple structure, good stability, and good wind resistance.

[0006] This utility model also provides a means of transportation, including handlebars and an adjustable-angle instrument device, which is convenient for users to operate.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] This utility model provides an adjustable angle instrument device, which is assembled on the handlebars of a bicycle and can stably maintain the set angle after adjustment; it includes:

[0009] A mount fixed to the handlebars; and an instrument panel rotatably attached to the mount about a predetermined axis;

[0010] An angle positioning mechanism is provided between the instrument panel and the base. This angle positioning mechanism is configured to restrict the rotation of the instrument device after it is adjusted to the set angle, and includes:

[0011] At least one pair of gear components, one configured to rotate with the instrument panel, and the other restricted from rotation; and one of the pair of gear components is subjected to a spring force and is movable, while the other is restricted from movement, so that during angle adjustment, the pair of gear components moves to a disengaged state against the spring force, and after the angle adjustment is completed, the pair of gear components is reset to an engaged state by the spring force.

[0012] The above technical solution can be further improved as follows:

[0013] Furthermore, the pair of gear components includes a first gear and a second gear capable of moving along the set axis and meshing or disengaging with each other.

[0014] Furthermore, the instrument panel has a pivot portion extending along the set axis, in which the first gear is received in a manner that allows it to move along the set axis.

[0015] Furthermore, the pivot portion has a receiving cavity extending along the set axis, and two first gears are spaced apart and facing each other along the set axis in the receiving cavity, with a return spring sandwiched between the two first gears.

[0016] Furthermore, the pivot portion has two receiving cavities spaced apart along the set axis. Each of the two receiving cavities has a first gear and a return spring. One end of the return spring abuts against the first gear, and the other end abuts against the bottom wall of the receiving cavity.

[0017] Furthermore, the first gear is configured to move and rotate with the instrument panel, while the second gear is fixed.

[0018] Furthermore, the first gear is configured to follow the rotation of the instrument panel but is restricted in movement, and the second gear is configured to be able to move along the set axis but is restricted in rotation.

[0019] Furthermore, the first gear has a first meshing surface perpendicular to the set axis, and the second gear has a second meshing surface perpendicular to the set axis, with a plurality of toothed portions arranged on both the first and second meshing surfaces.

[0020] Furthermore, the carrier has: a clamping part for securing the handlebars; a lamp support part for supporting the lighting lamp; and an instrument support part for supporting the instrument panel.

[0021] This utility model provides a means of transportation, including handlebars and an instrument device, wherein the instrument device is the one described above.

[0022] By adopting the above technical solution, this utility model has the following technical effects:

[0023] This utility model provides an adjustable-angle instrument device, including a base and an instrument panel that can rotate around a set axis to adjust the viewing angle, allowing users to flexibly adjust the viewing angle of the instrument panel according to their needs. Furthermore, an angle positioning mechanism is provided between the instrument panel and the base, comprising a first gear and a second gear that separate and mesh with each other. This not only facilitates the user's adjustment of the instrument panel's tilt angle but also ensures that the instrument panel can stably maintain the set angle after adjustment. Further, the meshing surfaces of the first and second gears are both perpendicular to the set axis, increasing the contact area between them. The meshing of multiple teeth further enhances the fixing force between the instrument panel and the base, giving the instrument panel good wind resistance and ensuring its stability. After angle adjustment, the first and second gears automatically mesh under the spring force provided by a return spring, achieving instrument panel positioning. The overall structural design is novel and ingenious, with high reliability. Attached Figure Description

[0043] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0044] Example 1

[0045] like Figures 1-7As shown, this utility model provides an adjustable-angle instrument device, which is assembled on the handlebars 8 of a bicycle and can stably maintain the set angle after adjustment. The instrument device includes a base 1 and an instrument panel 2, wherein the base 1 is fixed to the handlebars 8, and the instrument panel 2 is configured to rotate around a set axis L on the base 1 to adjust the angle of the instrument device. Furthermore, an angle positioning mechanism is provided between the instrument panel 2 and the base 1 to limit the rotation of the instrument device after the angle adjustment is completed, allowing the user to flexibly adjust the instrument panel according to usage needs. The viewing angle of the instrument panel 2 is adjusted to allow viewing of the displayed parameters. To enable the instrument panel 2 to be rotated more easily by the user and to be automatically fixed after the angle adjustment is completed, the angle positioning mechanism has at least one pair of gear components, one of which is configured to rotate with the instrument panel 2, and the other is restricted from rotating. Furthermore, one of the pair of gear components is subjected to a spring force and is movable, while the other is restricted from moving, so that during the angle adjustment process, the pair of gear components move to a disengaged state against the spring force, and after the angle adjustment is completed, the pair of gear components are reset to the engaged state by the spring force.

[0046] The pair of gear components includes a first gear 4 and a second gear 3 that can move along the set axis L and mesh or separate from each other. The first gear 4 is configured to move and rotate with the instrument panel 2, while the second gear 3 is fixedly disposed. The first gear 4 has a first meshing surface perpendicular to the set axis L, and the second gear 3 has a second meshing surface perpendicular to the set axis L. Both the first and second meshing surfaces are provided with a plurality of toothed portions. Specifically, the toothed portions on the first gear 4 and the second gear 3 are all inclined teeth. By adopting an inclined tooth structure design, when the user rotates the instrument panel 2, it will drive the first gear 4 to rotate. At the instant the first gear 4 rotates, the inclined tooth surface between the first gear 4 and the second gear 3 can generate a driving force. Under this driving force, the inclined tooth can guide the first gear 4 to separate from the second gear 3, thereby realizing the rotation of the instrument panel 2. When the instrument panel 2 stops rotating, the first gear 4 and the second gear 3 will return to the meshing state under the action of spring force, thereby realizing the fixation of the instrument panel 2. The above structural design allows users to adjust the viewing angle of the instrument panel 2 simply by pushing the instrument panel 2 to rotate. After the angle adjustment is completed, the angle positioning mechanism can automatically position the instrument panel 2, which facilitates user operation.

[0047] To make the overall structure of the instrument device more compact and aesthetically pleasing, the instrument panel 2 has a pivot portion 22 extending along the set axis L. The first gear 4 is received in the pivot portion 22 in a manner that allows it to move along the set axis L. Specifically, as shown... Figure 4-6As shown, the instrument panel 2 includes a housing 21 and a display module 24. The display module 24 is embedded in the housing 21 and includes a PCBA motherboard, a touch screen, and 2.5D tempered glass to ensure the display effect and robustness of the display module 24. The pivot portion 22 extending from the housing 21 along the set axis L not only allows the instrument panel 2 to rotate around the set axis L, but also allows the first gear 4 to be received in the pivot portion 22 in a manner that enables it to move along the set axis L. Specifically, the pivot portion 22 has a cavity for accommodating the first gear 4 and allowing the first gear 4 to move along the set axis L. The receiving cavity specifically includes a pivot groove 22a and a guide groove 22b. The pivot groove 22a is adapted to pivotally connect to the carrier 1, allowing the instrument panel 2 to rotate around the carrier 1. The first gear 4 and the return spring 5 are disposed in the guide groove 22b, which guides the first gear 4 to move. The guide groove 22b communicates with the pivot groove 22a, allowing the first gear 4 to mesh with the second gear 3 through the pivot groove 22a. In addition, a cover plate 23 is bolted to the housing 21 above the receiving cavity to seal and protect the first gear 4 and the return spring 5.

[0048] Specifically, such as Figure 7 As shown, the first gear 4 includes a gear body 41, teeth 42, and a boss 43 extending in the axial direction. The teeth 42 are located on the side of the gear body 41 facing the pivot groove 22a, and the teeth 42 are inclined, which can drive the first gear 4 to separate from the second gear 3 when the instrument panel 2 rotates. The boss 43 is located on the other side of the gear body 41 and is adapted to be attached to the return spring 5. Specifically, it can be embedded inside one end of the return spring 5 so that the return spring 5 can stably return the first gear 4. In addition, in order to limit the rotation of the first gear 4 along its own axis, This design makes the first gear 4 move more stably within the guide groove 22b. The first gear 4 has a limiting part. Preferably, the two side walls of the first gear 4 are set as straight edges 44 to form the limiting part. Correspondingly, the side walls of the guide groove 22b are configured as straight edges 44. This design is simple and can also convert the rotational force generated when the instrument panel 2 rotates into a force that moves the first gear 4 along the guide groove 22b, thereby separating it from the second gear 3. Furthermore, a stop is formed between the guide groove 22b and the pivot groove 22a, which can limit the first gear 4 from excessively squeezing the second gear 3 under the action of the return spring 5.

[0049] like Figure 9As shown, the pivot portion 22 has a receiving cavity extending along the set axis L. Two first gears 4 are spaced apart and facing each other along the set axis L within the receiving cavity. A return spring 5 is sandwiched between the two first gears 4. The two first gears 4 are respectively located at both ends of the pivot portion 22. Correspondingly, two second gears 3 are provided on the carrier 1. The two pairs of gear components provide support and positioning, which improves the stability of the instrument panel 2 on the carrier 1 and enhances the fixation effect of the instrument panel 2, preventing it from rotating under wind resistance during riding and improving usability.

[0050] Of course, the first gear 4 and the return spring 5 mentioned above can also adopt other structural designs, such as Figure 4-6 As shown, in this embodiment, the pivot portion 22 has two receiving cavities spaced apart along the set axis L. Each of the two receiving cavities contains a first gear 4 and a return spring 5. One end of the return spring 5 abuts against the first gear 4, and the other end abuts against the bottom wall of the receiving cavity. In some other embodiments, both the first gear 4 and the second gear 3 can move along the set axis L, but the second gear 3 is restricted from rotation or the first gear 4 is restricted from rotation. For those skilled in the art, any non-inventive modifications to the number and position of the first gear 4 and the return spring 5, inspired by the above embodiments, should fall within the protection scope of this patent.

[0051] In some embodiments, the pivot portion 22 has a receiving cavity extending along the set axis L. Two first gears 4 are spaced apart and facing each other along the set axis L in the receiving cavity. A return spring 5 is sandwiched between the two first gears 4 so as to simultaneously limit and support both sides of the instrument panel 2, making the rotation of the instrument panel 2 more stable, and also better fixing the instrument panel 2 after the angle adjustment is completed.

[0052] In this embodiment, the first gear 4 and the second gear 3 are both made of PA66-GF30, which has good mechanical damping and sliding properties. It maintains excellent wear resistance even when used in high-temperature environments. The material has high strength, stiffness, toughness, impact resistance, creep resistance and dimensional stability, which can effectively reduce the wear of the first gear 4 and the second gear 3 and ensure service life.

[0053] At least one carrier 1 is provided for supporting the instrument panel 2 so that it can rotate about a set axis L to adjust the viewing angle. In this embodiment, as... Figure 1 , 2As shown in Figures 3 and 5, a pair of carriers 1 are arranged opposite each other along the width direction of the handlebar 8. The pair of carriers 1 have a first clamping space between them to receive the instrument panel 2. Specifically, each carrier 1 includes a first arm 11, an instrument support 111, and a clamping part. One end of the first arm 11 extends along a set axis L to form a cylindrical protrusion, which forms the instrument support 111. The second gear 3 is fixed to the cylindrical protrusion, specifically by means of integral molding, screw connection, or welding. The instrument support 111 can be embedded in the pivot groove 22a on the instrument panel 2, realizing the pivot connection between the carrier 1 and the instrument panel 2. The end face gear of the second gear 3 can pass through the pivot groove 22a and mesh with the first gear 4 to position the instrument panel 2; the clamping part is provided at the other end of the first arm 11 for fixing to the handlebar 8. Specifically, the first arm 11 has a first semi-ring 112 at one end near the handlebar 8, and also includes a fixing member 12 that docks with the semi-ring. The shape of the fixing member 12 is adapted to the first semi-ring 112 and can be combined to form the clamping part. One end of the fixing member 12 is hinged to the first semi-ring 112, and the other end is bolted to the first semi-ring 112 for fixing the carrier 1 to the handlebar 8.

[0054] Furthermore, it also includes an inner ring 7, which is made of rubber and has flexibility and wear resistance. The carrier 1 is sleeved on the outside of the inner ring 7 to protect the handlebar 8. Specifically, the inner ring 7 has an opening 71 on its side wall, which can be used to fit handlebars 8 of different diameters. The carrier 1 clamps the inner ring 7 inside to better fix it to the handlebar 8. Preferably, the outer side wall of the inner ring 7 has an annular protrusion, and the inner side walls of the first semi-ring 112 and the second fixing member 12 both have embedded grooves. The annular protrusion can be engaged into the embedded grooves, so that the carrier 1 and the inner ring 7 are tightly connected, further improving the installation tightness of the instrument panel 2.

[0055] Furthermore, it also includes a fastening shaft 6, one end of which passes through the carrier 1, the first gear 4, and the second gear 3 in sequence, and is threadedly connected to the instrument panel 2. The fastening shaft 6 stably connects the instrument panel 2 and the carrier 1 together without affecting the rotation of the instrument panel 2. In this embodiment, the angle positioning mechanism is symmetrically provided between the two sides of the instrument panel 2 and the carrier 1. Preferably, the instrument panel 2 has a threaded hole in the middle that is threadedly connected to the fastening shaft 6. In some embodiments, a threaded sleeve can also be embedded in the middle of the instrument panel 2. The threaded sleeve has threaded holes on both the left and right sides, which can connect the fastening shafts 6 on both sides.

[0056] Example 2

[0057] like Figure 10 As shown, the difference between this embodiment and the above embodiment is that the first gear 4 is configured to follow the rotation of the instrument panel 2 but is restricted from moving, and the second gear 3 is configured to be able to move along the set axis L but is restricted from rotating.

[0058] In this embodiment, the carrier 1 has a receiving part that can accommodate the second gear 3 and the return spring 5. The second gear 3 is engaged with the first gear 4 under the elastic force of the return spring 5. When the instrument panel 2 rotates, the second gear 3 is driven away from the first gear 4 along the set axis L until it is separated. When the instrument panel 2 rotates to a suitable angle position, the second gear 3 is engaged with the first gear 4 under the elastic force of the return spring 5 to fix the instrument panel 2.

[0059] Example 3

[0060] like Figure 11-13 As shown, the difference between this embodiment and the above embodiment is that the carrier 1 also has a lamp support part 131, which is used to support the lighting lamp 9.

[0061] like Figure 12-13 As shown, in this embodiment, the carrier 1 further includes a second arm 13. One end of the second arm 13 extends forward toward the handlebar 8 and gradually slopes toward the center of the instrument panel 2. Its end is formed with a lamp support 131 suitable for fixing the lamp 9. The lamp 9 has a mounting part that cooperates with the lamp support 131. Its other end has a second semi-ring 132. The second semi-ring 132 cooperates with the first semi-ring 112 on the first arm 11 to close and form an annular clamping part for fixed installation on the handlebar 8. One end of the first semi-ring 112 is pivotally connected to the second semi-ring 132, and its other end is fixedly connected by a fastening bolt.

[0062] Furthermore, the lamp support part 131 and the mounting part have through holes for fastening bolts to pass through, and the lighting lamp 9 is stably installed on the carrier 1 by clamping and fixing with fastening bolts.

[0063] This utility model also provides a means of transportation, including handlebars 8 and an instrument device. The instrument device is the one described above. The means of transportation includes, but is not limited to, various means of transportation such as bicycles, electric bicycles, electric stepper bikes, and electric scooters. When riding this means of transportation, the user can adjust the viewing angle of the instrument panel 2 according to their own needs to facilitate the user to view the displayed parameters of the instrument panel 2.

[0064] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
