Description

Technical Field

[0001] This utility model relates to the field of mobility scooter technology, specifically to a lighting assembly and a mobility scooter. Background Technology

[0002] The lights on commuter vehicles are usually fixed optical components, meaning the position of the light fixture relative to the vehicle body remains constant. The style and appearance of the vehicle are distinguished only by the shape of the light fixture and its internal reflective surface, resulting in similar overall designs. While some commuter vehicles have lights that can be moved relative to the vehicle body for position adjustment, these often suffer from severe vibrations during riding, making it difficult to maintain the set position. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a lamp assembly that has the advantages of adjustable lamp component position and is less prone to vibration and abnormal noise during riding.

[0010] In some embodiments, the drive device is mounted on the frame and includes a motor and a reducer, the motor shaft being connected to the input shaft of the reducer, and the reducer output shaft being connected to the first connecting rod.

[0011] In some embodiments, the lamp assembly further includes a manual crank, the motor is a dual-axis motor, the first shaft of the dual-axis motor is connected to the input shaft of the reducer, and the second shaft of the dual-axis motor is detachably connected to the manual crank.

[0012] In some embodiments, the lamp assembly further includes an adapter, the manual crank is connected to the adapter, the adapter has a shaped hole, the outer contour of the cross-section of the second shaft of the dual-axis motor matches the outer contour of the cross-section of the shaped hole, and the second shaft is inserted into the shaped hole.

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The following is combined with Figures 1-4 Description of a lamp assembly 100 according to an embodiment of the present utility model.

[0027] The lighting assembly 100 of this embodiment includes a frame 1, a lighting component 2, a first link 3, a second link 4, and a drive device. The frame 1 is connected to the vehicle body 10, and the lighting component 2 is pivotally connected to the frame 1 between a concealed position and a raised position. The first end of the first link 3 is pivotally connected to the frame 1, the second end of the first link 3 is pivotally connected to the first end of the second link 4, and the second end of the second link 4 is pivotally connected to the lighting component 2. The frame 1, the lighting component 2, the first link 3, and the second link 4 constitute a linkage mechanism. At least one link in the linkage mechanism is pivotally connected to at least one adjacent link via a damper 5. The drive device is used to drive the lighting component 2 to rotate relative to the frame 1.

[0028] According to the lamp assembly 100 of this utility model embodiment, a linkage mechanism is formed by setting a first link 3, a second link 4, a lamp assembly 2, and a frame 1. Therefore, under the drive of the drive device, the rotational stability of the lamp assembly 2 relative to the frame 1 between the concealed position and the raised position is higher. Furthermore, by setting at least one link in the linkage mechanism to be pivotally connected to at least one adjacent link via a damper 5, the lamp assembly 2, located in the concealed and raised positions, is less prone to vibration and abnormal noise when subjected to instantaneous impacts during riding. The lamp assembly 2 can be more reliably maintained in the concealed and raised positions, resulting in a more aesthetically pleasing appearance for the mobility scooter.

[0029] It should be noted that in the aforementioned linkage mechanism, at least one link is pivotally connected to at least one adjacent link via a damper 5, meaning that the number of dampers 5 is at least four, that is, dampers 5 are integrated at all four pivot points of the linkage mechanism. For example, such as... Figure 1 and Figure 4 As shown, there is one damper 5, and the lamp assembly 2 is pivotally connected to the frame 1 through the damper 5.

[0030] In some embodiments, the linkage mechanism is a crank-rocker mechanism, and when the lamp assembly 2 is in the raised or hidden position, the crank-rocker mechanism is in the dead position.

[0031] Therefore, when the lighting assembly 2 is in the raised or concealed position, that is, when the crank-rocker mechanism is in the dead position, the crank-rocker mechanism is in a self-locking state. The lighting assembly 2 is less likely to disengage from the raised or concealed position due to external impact, resulting in higher position retention and greater reliability of the lighting assembly 100. Furthermore, this design eliminates the need for an additional self-locking mechanism, thus reducing the cost of the lighting assembly 100.

[0032] For example, such as Figures 1-4 As shown, the lamp assembly 2 is located on the upper side of the frame 1. The upper end of the lamp assembly 2 is pivotally connected to the upper end of the frame 1 via a damper 5. The lower end of the lamp assembly 2 in the concealed position is lower than the lower end of the lamp assembly 2 in the raised position. The crank rocker mechanism can be in the dead position only when the lamp assembly 2 is in the raised position, and in the non-dead position when the lamp assembly 2 is in the concealed position. At this time, the lamp assembly 2 can press against the body 10 of the mobility scooter under the action of gravity, which can also ensure the reliable holding of the lamp assembly 2 in the concealed position.

[0033] In some embodiments, the first link 3 is the crank portion of a crank-rocker mechanism, and the second link 4 is the rocker portion of a crank-rocker mechanism. When the lamp assembly 2 is in the raised position, the extension direction of the first link 3 is consistent with the extension direction of the second link 4.

[0034] The first link 3 and the second link 4 are generally hidden between the lamp assembly 2 and the frame 1 in the front-rear direction of the vehicle body 10. By setting the first link 3 and the second link 4 as the crank part and the rocker part respectively, they are less likely to be impacted by external forces. Therefore, when the crank rocker mechanism is in the dead position, the lamp assembly 2, which is in the raised position, is less likely to change position when it is impacted by external forces, and the decoration and lighting reliability of the lamp assembly 2 is higher.

[0035] For example, such as Figure 4 As shown, the distance between the two pivot axes on the first link 3 is A, the distance between the two pivot axes on the second link 4 is B, the distance between the two pivot axes on the lighting assembly 2 is C, and the distance between the two pivot axes on the frame 1 is D, where A < B, A+C > B+D. When the lighting assembly 2 is in the raised position, the second end of the second link 4, the first end of the second link 4, and the first end of the first link 3 are arranged sequentially at intervals along the extension direction of the first link 3.

[0036] In some embodiments, such as Figure 1 and Figure 4 As shown, the drive unit is mounted on the frame 1 and includes a motor 6 and a reducer 7. The rotating shaft of the motor 6 is connected to the input shaft of the reducer 7, and the output shaft of the reducer 7 is connected to the first connecting rod 3.

[0037] The reducer 7 reduces the speed and increases the torque of the motor 6, which not only reduces the size and cost of the motor 6, but also makes the movement accuracy of the lamp assembly 2 relative to the frame 1 between the hidden position and the raised position more precise, and the lamp assembly 100 has higher reliability.

[0038] For example, the reducer 7 and the motor 6 are fastened to the frame 1 by threaded parts, with the reducer 7 located in front of the motor 6 in the front-rear direction of the vehicle body 10.

[0039] In some embodiments, the lamp assembly 100 further includes a manual crank, the motor 6 is a dual-axis motor 6, the first axis of the dual-axis motor 6 is connected to the input shaft of the reducer 7, and the second axis of the dual-axis motor 6 is detachably connected to the manual crank.

[0040] Therefore, in the event of a power supply circuit failure in the dual-axis motor 6, the manual crank can be connected to the second shaft of the dual-axis motor 6. By manually cranking the second shaft, the lighting assembly 2 can be manually switched between a concealed position and a raised position, thus fulfilling the concealed function of the lighting assembly 2 when the vehicle is not started and the raised lighting function when the vehicle is started. Moreover, when the manual crank is not needed, it can be detached and stored away to prevent it from interfering with the user's normal use of the vehicle.

[0041] For example, such as Figure 1 and Figure 4As shown, the first and second shafts of the dual-axis motor 6 are coaxially connected. The second shaft is located behind the dual-axis motor 6 and behind the riser of the vehicle body 10. Therefore, when the position of the lamp assembly 2 needs to be manually switched, the manual crank has more assembly space, and the position switching of the lamp assembly 2 is more convenient.

[0042] In some embodiments, such as Figure 3 As shown, the lamp assembly 100 also includes an adapter 9, a manual crank is connected to the adapter 9, the adapter 9 is provided with a special-shaped hole, the outer contour of the cross-section of the second shaft of the dual-axis motor 6 matches the outer contour of the cross-section of the special-shaped hole, and the second shaft is inserted into the special-shaped hole.

[0043] Therefore, the manual crank can be set on the second axis through the adapter 9 to manually switch the lamp assembly 2 between the hidden position and the raised position. The manual crank is easy to assemble and disassemble from the second axis, without the need for additional auxiliary tools, and is easy to operate.

[0044] For example, adapter 9 is a sleeve that is coaxially welded to the end of the manual crank, or the sleeve is threaded to the end of the manual crank.

[0045] Optionally, the lamp assembly 100 also includes a manual crank, which is detachably connected to the first end of the first link 3 or the lamp assembly 2. That is, the manual crank can be directly connected to the first link 3 or the lamp assembly 2 to drive the first link 3 or the lamp assembly 2 to rotate relative to the frame 1, thereby adjusting the position of the lamp assembly 2. In this case, the motor 6 only needs to be a single-axis motor 6, which has lower cost and occupies less space in the vehicle body 10.

[0046] For example, the first end of the first link 3 is connected to a pivot, and the first link 3 is pivotally connected to the frame 1 via the pivot. The end of the manual crank is coaxially connected to the pivot.

[0047] In some embodiments, the lighting assembly 2 includes a luminaire 21 and a bracket 22, the bracket 22 being pivotally connected to the frame 1, the bracket 22 being pivotally connected to the second end of the second link 4, the luminaire 21 being snapped into the bracket 22, and / or the luminaire 21 being connected to the bracket 22 by a threaded connection.

[0048] Therefore, the installation of the lamp 21 on the bracket 22 is convenient and reliable, and the lamp 21 is easy to disassemble and assemble on the bracket 22. Moreover, the linkage mechanism is relatively independent of the lamp 21. If one of them is damaged, the other does not need to be scrapped at the same time, and the maintenance cost of the lamp assembly 100 is low.

[0049] For example, the lamp 21 can be snapped into the bracket 22 first to achieve the pre-positioning of the lamp 21 on the bracket 22, and then the threaded parts connect the lamp 21 and the bracket 22 to achieve the assembly of the lamp assembly 2, which has high assembly efficiency.

[0050] In some embodiments, there are two first links 3 and two second links 4, which correspond to each other. The two first links 3 are arranged at intervals along the rotation axis of the first links 3, and the two second links 4 are arranged at intervals along the rotation axis of the first links 3.

[0051] Therefore, with the joint support of the two sets of first connecting rods 3 and the two sets of second connecting rods 4, the bracket 22 has higher rotational stability relative to the frame 1, and the lamp 21 is less likely to tilt to the left or right during movement.

[0052] For example, such as Figure 3 As shown, the first ends of the two first links 3 are pivotally connected to the two ends of the frame 1 opposite to each other in the left-right direction along the vehicle body 10, and the second ends of the two second links 4 are pivotally connected to the two ends of the bracket 22 opposite to each other in the left-right direction along the vehicle body 10. The two ends of the output shaft of the reducer 7 are connected to the first ends of the two first links 3 respectively.

[0053] The mobility scooter according to an embodiment of the present invention includes a body 10 and a lamp assembly 100 as described in any of the above embodiments, with the frame 1 connected to the body 10.

[0054] The mobility scooter according to this utility model embodiment, by adopting the lamp assembly 100 of the above embodiment, has the advantages of adjustable position of lamp component 2, and is less prone to vibration and abnormal noise during riding. It also allows for diverse appearances and high aesthetic appeal.

[0055] It should be noted that the frame 1 is connected to the front end of the vehicle body 10, and the lighting assembly 2 is located in front of the frame 1. That is, the lighting assembly 2 is the headlight of the mobility scooter. The position of the headlight is adjustable, which makes the front of the mobility scooter flexible and interesting. It can stand out among many vehicles, making people's eyes light up and full of fun and a sense of ceremony.

[0056] For example, the front of the body 10 includes a riser and a handlebar assembly connected to the upper end of the riser, and the frame 1 is welded to the riser or detachably connected by a threaded connection.
