Description

Technical Field

[0001] This disclosure generally relates to light-emitting devices for vehicle lighting and methods of assembling them, vehicle lighting including the light-emitting devices, and vehicles including vehicle lighting. Background Technology

[0002] This section provides background information relating to this disclosure, but such information does not necessarily constitute prior art.

[0003] In recent years, vehicle lighting fixtures have increasingly adopted a more compact and flattened design. In related technologies, vehicle lighting fixtures may include multiple light-emitting devices, each capable of independently emitting illumination light at a specific angle. These emitted lights are then combined to form a final, complete light pattern. Typically, to obtain an ideal light pattern, the illumination light emitted by each light-emitting device needs to be adjusted individually to ensure the alignment of the HV point and cutoff line of each device. Therefore, how to precisely adjust the light emitted by each light-emitting device has become a pressing issue. Furthermore, there is room for improvement in how to fix the position of the adjusted light-emitting devices in related technologies. Summary of the Invention

[0004] This section provides a general overview of this disclosure, rather than a full disclosure of its entire scope or all its features.

[0005] Embodiments of this disclosure can provide a light-emitting device for a vehicle lamp. The light-emitting device may include: a light-emitting unit configured to emit illumination light, the light-emitting unit may include a rod extending forward in a longitudinal direction from an end face of the light-emitting unit, and a screw mounting hole may be provided on the light-emitting unit; a mounting member disposed in front of the light-emitting unit and may include a mounting hole for the rod to extend through, the mounting member may be configured as a fastener for fixing to the vehicle lamp; and a locking device, the locking device may include a locking plate and a spring bolt, the spring bolt may include a screw and a bolt head, the locking plate may be disposed in front of the mounting member in the longitudinal direction and may include a locking hole for the rod to extend through, the rod may extend through the mounting hole and the locking hole and protrude forward beyond the locking plate, and the end of the rod protruding forward beyond the locking plate may be actuated at a position on the locking plate different from the locking hole. The mounting member is provided with a screw guide hole, through which a screw can pass longitudinally and rearward through the screw guide hole and be screwed into the screw mounting hole. The screw head can abut against the front surface of the locking plate. The tightening torque provided by the spring bolt allows the light-emitting device to be fixed relative to the mounting member in the non-actuated state of the rod, and to be movable relative to the mounting member in the lateral and / or vertical direction in the actuated state of the rod, thereby allowing the position of the light-emitting device to be adjusted in the lateral and / or vertical direction. The locking plate can be configured such that after the position of the light-emitting device is adjusted into place in the lateral and / or vertical direction, the locking plate can be fixed to the mounting member. The locking plate can include a rib extending forward longitudinally from the front surface of the locking plate, the rib defining a receiving cavity in which a first fixing device can be provided. The first fixing device is an adhesive formed by curing an adhesive injected into the receiving cavity.

[0006] In one embodiment, the adhesive forming the first fixing device can be a glue that can be cured by ultraviolet light.

[0007] In one implementation, the rib may extend beyond the bolt head in the longitudinal direction.

[0008] In one embodiment, the rod protrudes forward beyond the receiving cavity in the longitudinal direction; and the first fixing device may also be configured to fix the rod in the receiving cavity after the position of the light-emitting device has been adjusted into place in the lateral and / or vertical directions.

[0009] In this embodiment, the tightening torque of the spring bolt is less than 1 Nm, preferably 0.1 Nm to 0.5 Nm.

[0010] In an embodiment, the light-emitting device may further include a second fixing device, which may be disposed between the locking plate and the rod, and may be configured to fix the rod relative to the locking plate before adjusting the position of the light-emitting device in the lateral and / or vertical directions, thereby allowing the locking plate to always move together with the light-emitting device when the rod is actuated.

[0011] In one embodiment, the second fixing device may be disposed in the locking hole and surround the rod, and the second fixing device is at least one of an adhesive device, a lining device, and a mechanical fixing device.

[0012] In one embodiment, the bonding device can be an adhesive formed by injecting adhesive around the rod into the locking hole and curing the injected adhesive.

[0013] In one embodiment, the adhesive forming the second fixing device can be a glue that can be cured by ultraviolet light.

[0014] In one embodiment, the mounting components may include a first mounting member disposed in front of the light-emitting device and a second mounting member disposed in front of the first mounting member. Both the first and second mounting members may include the mounting holes through which the rod extends. The light-emitting device is movable relative to the first mounting member in either a lateral or vertical direction, and the first mounting member is movable relative to the second mounting member in either a lateral or vertical direction, thereby allowing the position of the light-emitting device to be adjusted in both the lateral and vertical directions.

[0015] Embodiments of this disclosure may also provide a vehicle lamp, which may include at least one of the aforementioned light-emitting devices, wherein the illumination emitted by each light-emitting device is combined to form the light pattern of the vehicle lamp.

[0016] Embodiments of this disclosure may also provide a vehicle, which may include the aforementioned vehicle lights.

[0017] Embodiments of this disclosure may also provide an assembly method for assembling the aforementioned light-emitting device. The assembly method may include: passing a rod of the light-emitting device through a mounting hole in a mounting member to position the mounting member in front of the light-emitting device; passing the rod through a locking hole in a locking plate to mount the locking plate on the side of the mounting member opposite to the light-emitting device, and extending the rod to protrude beyond the locking plate; connecting a screw to a screw mounting hole in the light-emitting device by passing a screw through the locking plate and the mounting member in sequence, and abutting the bolt head against the front surface of the locking plate to provide a tightening torque to the light-emitting device and the mounting member; actuating the rod to move the light-emitting device relative to the mounting member in a lateral and / or vertical direction to adjust the position of the light-emitting device in the lateral and / or vertical direction; fixing the locking plate to the mounting member; and injecting an adhesive forming the first fixing device into a receiving cavity and curing the adhesive forming the first fixing device, so that the light-emitting device cannot move in the lateral and vertical directions in either the actuated or non-actuated state.

[0018] In one embodiment, injecting the adhesive forming the first fixing device into the receiving cavity includes injecting an adhesive that can be cured by ultraviolet light into the receiving cavity; and curing the adhesive forming the first fixing device includes curing the adhesive injected into the receiving cavity by ultraviolet light.

[0019] In one implementation, the ribs can extend beyond the bolt head in the longitudinal direction.

[0020] In one embodiment, the rod may protrude forward beyond the receiving cavity in the longitudinal direction; and the assembly method may further include: after the position of the light-emitting device is adjusted in the lateral and / or vertical direction, fixing the rod in the receiving cavity by a first fixing device.

[0021] In the implementation, the tightening torque can be set to less than 1 Nm, preferably to 0.1 Nm to 0.5 Nm.

[0022] In an embodiment, the assembly method may further include: before actuating the rod, placing a second fixing device between the locking plate and the rod to fix the rod relative to the locking plate, thereby allowing the locking plate to always move together with the light-emitting device when the rod is actuated.

[0023] In one embodiment, placing the second fixing device between the locking plate and the rod may include: injecting an adhesive forming the second fixing device around the rod into the locking hole to fill the gap between the locking hole and the rod; and curing the adhesive forming the second fixing device.

[0024] In one embodiment, injecting the adhesive forming the second fixing device into the locking hole around the rod may include injecting an adhesive that can be cured by ultraviolet light into the locking hole; and curing the adhesive forming the second fixing device may include curing the adhesive injected into the locking hole by ultraviolet light.

[0025] In an embodiment, the assembly method may include: before injecting the adhesive forming the second fixing device around the rod into the locking hole, screwing the screw such that the light-emitting device cannot move relative to the mounting member in either the actuated or non-actuated state of the rod; and after curing the adhesive injected into the locking hole, screwing the screw to provide a fastening torque to the light-emitting device and the mounting member.

[0026] According to the above configuration, after the position of the light-emitting device is adjusted to the correct position in the horizontal and / or vertical directions, the locking plate is fixed to the mounting component, and a first fixing device is provided in the accommodating cavity. This prevents the light-emitting device from moving horizontally or vertically even when actuated, thus achieving complete fixation of the light-emitting device without the need for secondary tightening of the spring bolt. Therefore, according to the above configuration, the fastening effect of each component of the light-emitting device can be achieved without secondary tightening of the spring bolt, while the first fixing device also prevents the spring bolt itself from falling off. In this way, the relative displacement between the components of the light-emitting device after adjustment caused by secondary tightening of the spring bolt (i.e., re-tightening of the spring bolt after the position of the light-emitting device is adjusted to the correct position in the horizontal and / or vertical directions) in related technologies is avoided. This displacement may be caused by component deformation due to the non-rigidity of each component of the light-emitting device during secondary tightening of the spring bolt, or by rotation or movement caused by the installation gaps between the components of the light-emitting device (including the radial gaps between the spring bolt and the other components of the light-emitting device). Therefore, based on the above configuration, since there is no need to tighten the spring bolts a second time, the relative displacement between the components of the light-emitting device after it has been adjusted to the correct position can be avoided, thereby avoiding the change in the light pattern of the vehicle lamps caused by such relative displacement and the resulting deterioration in lighting performance.

[0027] In addition, by setting the first fixing device, the bonding area between the rod and the locking plate can be increased, thereby increasing the bonding force between the rod and the locking plate, making the fixing more reliable.

[0028] Furthermore, in some embodiments, by providing a second fixing device, the locking plate can always move together with the light-emitting device during the adjustment process, thereby reducing the impact on adjustment accuracy, especially in the initial stage of adjustment, due to differences in the applied force. In addition, the fixing force provided by the second fixing device enhances the stability of the fixing between the rod and the locking plate, and together with the spring bolt, it connects and fixes the locking plate and the light-emitting device, thereby further improving the stability of the light-emitting device during adjustment, and thus improving the dimming accuracy.

[0037] The present disclosure will now be described in detail with reference to the accompanying drawings and exemplary embodiments. It should be noted that the following detailed description of the present disclosure is for illustrative purposes only and is not intended to limit the scope of the disclosure. Furthermore, the same reference numerals are used to denote the same parts in the various drawings.

[0038] It should also be noted that, for clarity, not all features of the actual specific embodiments are described and shown in the specification and drawings. Furthermore, in order to avoid unnecessary details obscuring the technical solutions of this disclosure, only the device structures closely related to the technical solutions of this disclosure are described and shown in the drawings and specification, while other details that are not closely related to the technical content of this disclosure and are known to those skilled in the art are omitted.

[0039] Next, a vehicle lighting fixture provided according to an exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0040] In some embodiments, the vehicle lamps according to this disclosure may include at least one light-emitting device 1, wherein the illumination emitted by each light-emitting device 1 can be combined to form the complete light pattern of the vehicle lamp. To this end, in order to ensure the alignment of the HV point (the perpendicular from the horizontal line passing through the reference center of the vehicle lamp to the foot of the perpendicular on the light distribution screen) and the cutoff line (the boundary line where a significant change in brightness is visually perceived when the light beam emitted by the vehicle lamp is projected onto the light distribution screen) of each light-emitting device 1 according to this disclosure, the light emitted by each light-emitting device 1 can be adjusted. The light-emitting device 1 for a vehicle lamp according to an exemplary embodiment of this disclosure will now be described in detail with reference to the accompanying drawings.

[0041] Figures 1 to 4 An assembled perspective view and an exploded perspective view of a light-emitting device 1 for a vehicle lamp according to an exemplary embodiment of the present disclosure are shown. (Refer to...) Figures 1 to 4 The light-emitting device 1 may include a light-emitting element 10, which can be configured to emit illumination light. The light-emitting element 10 may include a rod 100 extending forward in a longitudinal direction from its end face. A screw mounting hole 102 may be provided on the light-emitting element 10, such as... Figures 2 to 4 As shown in the image.

[0042] In some embodiments, the light-emitting device 1 may further include a mounting member 20, which may be arranged in front of the light-emitting device 10 and may include a mounting hole for the rod 100 to extend through. It should be noted that the mounting member 20 may be configured as a fastener for fixing to a vehicle lamp.

[0043] Reference Figures 1 to 4The light-emitting device 1 may include a locking device 30, which may include a locking plate 301 and a spring bolt 302. The spring bolt 302 may include a screw 3021 and a bolt head 3022. The locking plate 301 is arranged in the longitudinal direction in front of the mounting member 20, that is, on the side of the mounting member 20 opposite to the light-emitting device 10. Furthermore, the locking plate 301 may include a locking hole 3011 for the rod 100 to extend through, such as... Figure 5 As shown in the figure. The rod 100 extends through the mounting hole and the locking hole 3011 and protrudes forward beyond the locking plate 301, and the end of the rod 100 that protrudes forward beyond the locking plate 301 can be actuated, that is, the rod 100 can be adjusted by an external adjustment device, so that the rod 100 can swing up and down and left and right, thereby driving the light-emitting device 10 to swing up and down and left and right.

[0044] like Figure 5 As shown, a screw guide hole 3012 is provided on the locking plate 301 at a position different from the locking hole 3011. A screw 3021 can pass through the screw guide hole 3012 longitudinally through the mounting member 20 and be screwed into the screw mounting hole 102, with the bolt head 3022 abutting against the front surface of the locking plate 301. In some embodiments, the tightening torque provided by the spring bolt 302 allows the light-emitting device 10 to be fixed relative to the mounting member 20 in the non-actuated state of the rod 100, while in the actuated state of the rod 100, the light-emitting device 10 can move relative to the mounting member 20 in the lateral and / or vertical directions, thereby allowing adjustment of the position of the light-emitting device 10 in the lateral and / or vertical directions.

[0045] In this manner, according to the vehicle lighting fixture provided in this disclosure, when the rod 100 is not actuated, the light-emitting device 10 is mounted to the mounting member 20 in a non-movable manner by the tightening torque provided to the light-emitting device 10 and the mounting member 20 by the spring bolt 302, thereby ensuring the stability of the light-emitting device 1. When the rod 100 is actuated, the position of the light-emitting device 10 can be adjusted in the lateral and / or vertical directions, thereby adjusting the direction of the light emitted from the light-emitting device 10, thereby adjusting the position of the light pattern projected by the light-emitting device 10, and thus obtaining the ideal light pattern of the vehicle lighting fixture.

[0046] It is understandable that, since the mounting component 20 is constructed as a fixed part to the vehicle lamp, the vibration generated by the vehicle during operation may be transmitted to the mounting component 20. If the spring bolt 302 is not fully tightened at this time, the light-emitting device 10 will rotate or move relative to the mounting component 20, causing the light pattern of the vehicle lamp to change, which in turn leads to a deterioration in lighting performance.

[0047] While it is conceivable that the spring bolt 302 be tightened again after the position of the light-emitting device 10 has been adjusted to prevent relative displacement between the components of the adjusted light-emitting device 1 due to vehicle vibration, it should be noted that if the spring bolt 302 is tightened directly after the position of the light-emitting device 10 has been adjusted to be in place, it may cause the already adjusted light-emitting device 10 to rotate or move relative to the mounting member 20. Furthermore, even after the spring bolt 302 is fully tightened, although the light-emitting device 10, the locking plate 301, and the mounting member 20 are fixed axially by the spring bolt, there is still a certain radial clearance between the spring bolt 302 and the other components of the light-emitting device 1, and there is also a small installation clearance between the light-emitting device 10 and the locking plate 301 or the mounting member 20. Therefore, under harsh vehicle operating conditions, strong vibrations may cause the light-emitting device 10 to deflect slightly radially, resulting in changes in light pattern and consequently, a deterioration in lighting performance.

[0048] Furthermore, although it is conceivable that the spring bolt 302 is tightened after the locking plate 301 is fixed to the mounting member 20 to prevent rotation or movement of the light-emitting device 10 relative to the mounting member 20 during the tightening of the spring bolt 302, it is understandable that in this case, since the various components of the light-emitting device 1 are not perfectly rigid, the various components of the light-emitting device 1 that have been adjusted into place will undergo microscopic deformation when the spring bolt 302 is tightened a second time. In addition, it is also understandable that there must be a radial installation gap between the spring bolt 302 and the other components of the light-emitting device 1, and there is also a certain installation gap between the light-emitting device 10 and the mounting member 20 or the locking plate 301. Therefore, when the spring bolt 302 is tightened a second time, there will be rotation or movement between the locking plate 301 and the mounting member 20, causing the light-emitting device 10 to deflect and resulting in a change in the final light pattern of the vehicle lamp.

[0049] In this regard, according to the present disclosure, in some embodiments, the locking plate 301 may be configured such that after the position of the light-emitting device 10 is adjusted into place in the lateral and / or vertical directions, the locking plate 301 is fixed to the mounting member 20. Furthermore, the locking plate 301 may include a rib 3013 extending forward in the longitudinal direction (front-back direction) from the front surface of the locking plate 301, the rib 3013 defining a receiving cavity 3014 in which a first fixing device 40 may be provided. The first fixing device 40 is an adhesive formed by curing an adhesive injected into the receiving cavity 3014.

[0050] In this manner, according to the light-emitting device 1 provided in this disclosure, after the position of the light-emitting device 10 is adjusted to the correct position in the horizontal and / or vertical directions, the locking plate 301 is fixed to the mounting member 20, and a first fixing device 40 is provided in the receiving cavity 3014. This prevents the light-emitting device 10 from moving in the horizontal and vertical directions even when actuated; that is, the light-emitting device 10 is completely fixed without the need for secondary tightening of the spring bolt 302. Therefore, according to the light-emitting device 1 provided in this disclosure, the fastening effect of each component of the light-emitting device 1 can be achieved without the need for secondary tightening of the spring bolt 302, while the first fixing device 40 also prevents the spring bolt 302 from falling off. In this way, the relative displacement between the components of the light-emitting device 1 after adjustment is avoided due to secondary tightening of the spring bolt 302 (i.e., re-tightening of the spring bolt after the position of the light-emitting device is adjusted to the correct position in the horizontal and / or vertical directions) in related technologies. As mentioned above, this displacement may be caused by component deformation due to the non-rigidity of the various components of the light-emitting device 1 during the secondary tightening of the spring bolt 302, as well as by rotation or movement caused by the installation gaps between the various components of the light-emitting device 1 (including the radial gaps between the spring bolt 302 and the other components of the light-emitting device 1). Therefore, the light-emitting device 1 provided according to the exemplary embodiment of this disclosure, since it does not require secondary tightening of the spring bolt 302, can avoid relative displacement between the various components of the light-emitting device 1 after it has been adjusted to the correct position, thereby avoiding changes in the light pattern of the vehicle lamps caused by such relative displacement, and thus avoiding deterioration in lighting performance.

[0051] It should be noted that after the position of the light-emitting device 10 is adjusted into place in the lateral and / or vertical directions, the locking plate 301 can be fixed to the mounting member 20 in any suitable manner. Preferably, the locking plate 301 can be fixed to the front surface of the mounting member 20. Furthermore, it is conceivable that the rear surface of the locking plate 301 can be fixed to the front surface of the mounting member 20 by welding, bonding, or other means, and this disclosure does not limit this.

[0052] In some embodiments, the adhesive forming the first fixing device 40 may be a glue that can be cured by ultraviolet light.

[0053] In some embodiments, the rib 3013 may extend beyond the bolt head 3022 in the longitudinal direction, thereby ensuring that the entire bolt head 3022 is completely embedded in the receiving cavity 3014, thus avoiding unintentional contact with the bolt head 3022 and further improving the stability of the final light-emitting device 1.

[0054] In some embodiments, the rod 100 may protrude forward in the longitudinal direction beyond the receiving cavity 3014, such as Figure 1 , Figure 6 and Figure 7 As shown in the diagram, the first fixing device 40 can be configured to fix the rod 100 in the receiving cavity 3014 after the position of the light-emitting device 10 has been adjusted into place in the lateral and / or vertical directions. In this way, by providing the first fixing device 40, the bonding area between the rod 100 and the locking plate 301 can be increased, thereby increasing the bonding force between the rod 100 and the locking plate 301, making the fixation more reliable.

[0055] In some embodiments, the spring bolt is tightened to a tightening torque of less than 1 Nm, preferably 0.1 Nm to 0.5 Nm. In this way, the spring bolt allows the light-emitting device 10 to be fixed relative to the mounting member 20 in the non-actuated state of the rod 100, while allowing adjustment of the position of the light-emitting device 10 in the lateral and / or vertical directions perpendicular to the longitudinal direction in the actuated state of the rod 100.

[0056] It should be noted that, without departing from the scope of this disclosure, the light-emitting device 10 described above can be moved relative to the mounting member 20 in any suitable manner in the lateral and / or vertical directions, and this disclosure does not limit it in any way.

[0057] For example, in some implementations, such as Figure 2 As shown, the light-emitting device 10 may include a lateral guide portion 101 extending forward in the longitudinal direction from the end face of the light-emitting device 10. Preferably, the lateral guide portion 101 has a screw mounting hole 102, and the mounting member 20 may be provided with a lateral elongated groove 200 for providing the mounting hole. The lateral guide portion 101 may be fitted into the lateral elongated groove 200. Furthermore, the light-emitting device 10 may include a vertical guide portion 103 extending forward in the longitudinal direction from the end face of the light-emitting device 10, and the surface of the mounting member 20 facing the light-emitting device 10 may be provided with a vertical guide groove that mates with the vertical guide portion 103. The vertical guide portion 103 can move vertically along the vertical guide groove. It is understood that the dimensions of the vertical guide portion 103 of the light-emitting device 10 and the vertical guide groove of the mounting member 20 are matched in the lateral direction to limit the movement of the light-emitting device 10 relative to the mounting member 20 in the lateral direction. In this way, the light-emitting device 10 can only move relative to the mounting member 20 in the vertical direction.

[0058] It should be pointed out that, although in Figure 2The illustration shows an embodiment where the light-emitting device 10 can only move relative to the mounting member 20 in the vertical direction. However, it is conceivable that in some embodiments, the light-emitting device 10 may also be configured to move relative to the mounting member 20 only in the lateral direction. For example, in some embodiments, no vertical guide portion may be included at the end face of the light-emitting device 10, and the lateral guide portion 101 of the light-emitting device 10 may be fitted into the lateral elongated groove 200 of the mounting member 20 and can move in the lateral direction along the lateral elongated groove 200. Furthermore, the lateral elongated groove 200 of the mounting member 20 may also be provided with a limiting portion for restricting the vertical movement of the light-emitting device 10, or the vertical dimension of the lateral elongated groove 200 may be set to match the vertical dimension of the lateral guide portion 101. In this way, the light-emitting device 10 can be moved relative to the mounting member 20 only in the lateral direction.

[0059] Furthermore, it is conceivable that in some embodiments, the light-emitting device 10 can be configured to be movable relative to the mounting member 20 in both the lateral and vertical directions. Referring below... Figure 3 and Figure 4 This implementation method will be described in detail.

[0060] like Figure 3 and Figure 4 As shown, in some embodiments, the mounting member 20 may include a first mounting member 201 disposed in front of the light-emitting device 10 and a second mounting member 202 disposed in front of the first mounting member 201, and both the first mounting member 201 and the second mounting member 202 may include mounting holes for the rod 100 to extend through. In some embodiments, the first mounting member 201 and the second mounting member 202 may be provided with transverse elongated slots 2010 and 2020 aligned with each other in the longitudinal direction, and the mounting holes of the mounting member 20 may be provided by the transverse elongated slots 2010 and 2020.

[0061] Understandably, the light-emitting device 10 can move relative to the first mounting member 201 in either the lateral or vertical direction, while the first mounting member 201 can move relative to the second mounting member 202 in either the lateral or vertical direction, thereby allowing the position of the light-emitting device 10 to be adjusted in both the lateral and vertical directions.

[0062] For example, in some exemplary embodiments, such as Figure 3 and Figure 4As shown, the light-emitting device 10 may include a transverse guide portion 101 extending forward in the longitudinal direction from the end face of the light-emitting device 10. Preferably, the transverse guide portion 101 has a screw mounting hole 102, and the transverse guide portion 101 can be fitted into a transverse elongated groove 2010 and can move in the transverse direction along the transverse elongated groove 2010. It is understood that the transverse elongated groove 2010 of the first mounting member 201 may also be provided with a limiting portion for restricting the movement of the light-emitting device 10 in the vertical direction, or the vertical dimension of the transverse elongated groove 200 may be set to match the vertical dimension of the transverse guide portion 101, so that the light-emitting device 10 can only move relative to the first mounting member 201 in the transverse direction. In addition, the first mounting member 201 may have a vertical protrusion 2012 on the surface facing the second mounting member 202, and the second mounting member 202 may have a vertical elongated groove that cooperates with the vertical protrusion 2012 on the surface facing the first mounting member 201. Understandably, the vertical protrusion 2012 of the first mounting member 201 and the vertical guide groove of the second mounting member 202 are matched in the lateral direction to restrict the movement of the first mounting member 201 relative to the second mounting member 202 in the lateral direction, thereby allowing the first mounting member 201 to move only in the vertical direction relative to the second mounting member 202. In this way, the position of the light-emitting device 10 can be adjusted in both the lateral and vertical directions.

[0063] It is understood that the embodiments described above are merely exemplary, and various modifications can be conceived by those skilled in the art without departing from the spirit and scope of this disclosure, and such modifications should be considered to fall within the scope of this disclosure. For example, although in the embodiments described above, the light-emitting device 10 can only move in the lateral direction relative to the first mounting member 201 and the first mounting member 201 can only move in the vertical direction relative to the second mounting member 202, those skilled in the art can conceive that the light-emitting device 10 can also be made to move only in the vertical direction relative to the first mounting member 201, and the first mounting member 201 can only move in the lateral direction relative to the second mounting member 202, which will not be described in detail in this application.

[0064] It is also conceivable that each mounting surface of the light-emitting device 10 and the mounting component 20 can be an arc surface, so that the light-emitting device 10 can rotate relative to the mounting component 20, thereby adjusting the tilt angle of the light-emitting device 10, that is, the light-emitting device 10 can rotate up, down, left and right, thereby adjusting the light emission direction of the vehicle lamp, and thus adjusting the light shape position of the vehicle lamp to ensure the lighting effect.

[0065] Furthermore, the applicant of this disclosure has discovered that the tightening torque provided by the spring bolt 302 allows the light-emitting device 10 to be fixed relative to the mounting member 20 when the rod 100 is in an unactuated state. At this time, by adjusting the rod 100 (i.e., by actuating the rod 100), the locking plate 301 and the light-emitting device 10 can be moved together relative to the mounting member 20 in the lateral and / or vertical directions to achieve adjustment of the position of the light-emitting device 10 in the lateral and / or vertical directions. As mentioned above, the rod 100 extends through the locking hole 3011 of the locking plate 301. Even with precise manufacturing, a radial installation gap may still exist between the locking plate 301 and the rod 100. Therefore, in the initial stage of adjustment, the light-emitting device 10 and the locking plate 301 may not be completely synchronized, causing the force exerted by the adjusting device on the light-emitting device 10 during the adjustment process to change, thereby affecting the adjustment accuracy of the light-emitting device 10.

[0066] In some embodiments, the light-emitting device 1 may further include a second fixing device 50 disposed between the locking plate 301 and the rod 100, such as Figures 1 to 4 As shown in the diagram. The second fixing device 50 can be configured such that, before adjusting the position of the light-emitting device 10 in the lateral and / or vertical directions, the rod 100 is fixed relative to the locking plate 301, thereby allowing the locking plate 301 to always move together with the light-emitting device 10 when the rod 100 is actuated. In this way, by providing the second fixing device 50, the locking plate 301 can always move together with the light-emitting device 10 during adjustment, thereby reducing the impact on adjustment accuracy that may be caused by different forces. In addition, the fixing force provided by the second fixing device 50 can enhance the fixing stability between the rod 100 and the locking plate 301, and together with the spring bolt 302, it connects and fixes the locking plate 301 and the light-emitting device 10, thereby further improving the stability of the light-emitting device 1 during the adjustment of the light-emitting device 10, and thus improving the dimming accuracy.

[0067] The following description will focus on some exemplary implementations of the second fixing device 50 with reference to the accompanying drawings.

[0068] In some embodiments, the second fixing device 50 may be disposed in the locking hole 3011 and surround the rod 100 to fill the gap between the locking hole 3011 and the rod 100. For example, the second fixing device 50 may be an adhesive device. In some embodiments, such as Figure 2 and Figure 3 As shown, the bonding device can be an adhesive formed by injecting adhesive around the rod 100 into the locking hole 3011 and curing the injected adhesive. Preferably, the adhesive can be a glue that can be cured by ultraviolet light.

[0069] In other embodiments, the second fixing device 50 may be a liner device disposed in the locking hole 3011 and surrounding the rod 100. For example, the liner device may be made of an elastic material and can be pressed between the locking hole 3011 and the rod 100. It is also conceivable that the liner device may include a plurality of elastic members arranged spaced apart from each other around the rod 100, wherein each elastic member is pressed between the locking hole 3011 and the rod 100. Furthermore, the liner device may also be a rigid member disposed in the locking hole 3011 and surrounding the rod 100, the thickness of which is configured to completely fill the gap between the locking hole 3011 and the rod 100, so that the locking plate 301 always moves together with the light-emitting device 10 when the rod 100 is actuated.

[0070] Furthermore, it is conceivable that the second fixing device 50 may also be a mechanical fixing device disposed in the locking hole 3011 and surrounding the rod 100. For example, in some embodiments, the second fixing device 50 may be at least one wedge-shaped member disposed between the locking hole 3011 and the rod 100. Additionally, other mechanical fixing devices are conceivable; for example, the second fixing device 50 may include a groove provided in the inner wall of the locking hole 3011 and a protrusion projecting from a corresponding position on the rod 100.

[0071] In other embodiments, the second fixing device 50 may be a screw device disposed between the locking plate 301 and the rod 100. For example... Figure 4 As shown, the second fixing device 50 may include a first screw device extending vertically downward from the upper wall of the locking plate 301 to the upper portion of the rod 100, and a second screw device extending vertically upward from the lower wall of the locking plate 301 to the lower portion of the rod 100. It is understood that, although not shown in the figures, the second fixing device 50 may also include two screw devices extending laterally from the two side walls of the locking plate 301 to the rod 100. In this way, the position of the rod 100 of the light-emitting device 10 can be completely fixed relative to the locking plate 301, so that the locking plate 301 always moves together with the light-emitting device 10 when the rod 100 is actuated.

[0072] It should be understood that the structure of the second fixing device 50 described above is exemplary and not limiting, and the second fixing device 50 can be set in any suitable manner, as long as it enables the locking plate 301 to always move together with the light-emitting device 10 when the rod 100 is actuated.

[0073] According to exemplary embodiments of this disclosure, a vehicle lamp including at least one light-emitting device 1 and a vehicle including the aforementioned vehicle lamp are also provided. It is understood that the vehicle lamp and vehicle provided by this disclosure are at least able to achieve the various advantages described above regarding the vehicle lamp.

[0074] Next, an assembly method for assembling the light-emitting device 1 according to an exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. For the sake of brevity, redundant details will not be elaborated.

[0075] According to an exemplary embodiment of this disclosure, an assembly method for assembling the aforementioned light-emitting device 1 is provided. This assembly method may include: passing a rod 100 of the light-emitting device 10 through the mounting hole of the mounting member 20 to position the mounting member 20 in front of the light-emitting device 10; passing the rod 100 through the locking hole 3011 of the locking plate 301 to mount the locking plate 301 on the side of the mounting member 20 opposite to the light-emitting device 10, and extending the rod 100 to protrude beyond the locking plate 301; and connecting the screw 3021 of the spring bolt 302 to the screw mounting hole 10 of the light-emitting device 10 by sequentially passing through the locking plate 301 and the mounting member 20. 2. The bolt head 3022 is abutted against the front surface of the locking plate 301 to provide the tightening torque to the light-emitting device 10 and the mounting member 20; the rod 100 is actuated so that the light-emitting device 10 moves relative to the mounting member 20 in the lateral and / or vertical directions to adjust the position of the light-emitting device 10 into place in the lateral and / or vertical directions; the locking plate 301 is fixed to the mounting member 20, and the adhesive forming the first fixing device 40 is injected into the receiving cavity 3014 and cured so that the light-emitting device 10 cannot move in the lateral and vertical directions in either the actuated or non-actuated state. It is understood that the assembly method provided according to the exemplary embodiment of this disclosure can provide at least the same advantages as the aforementioned light-emitting device 1. For simplicity, further details will not be provided here.

[0076] In some embodiments, injecting the adhesive forming the first fixing device 40 into the receiving cavity 3014 includes injecting an adhesive capable of curing by ultraviolet light into the receiving cavity 3014. Furthermore, curing the adhesive forming the first fixing device 40 may include curing the adhesive injected into the receiving cavity 3014 by ultraviolet light.

[0077] In some embodiments, the assembly method may include: before actuating the rod 100, placing a second fixing device 50 between the locking plate 301 and the rod 100, so that the rod 100 is fixed relative to the locking plate 301, thereby allowing the locking plate 301 to always move together with the light-emitting device 10 when the rod 100 is actuated. In this way, by setting the second fixing device 50, the locking plate 301 can always move together with the light-emitting device 10 during adjustment, thereby reducing the impact on adjustment accuracy that may be caused by different forces. In addition, the fixing force provided by the second fixing device 50 can enhance the fixing stability between the rod 100 and the locking plate 301, and together with the spring bolt 302, connect and fix the locking plate 301 and the light-emitting device 10, thereby further improving the stability of the light-emitting device 1 during the adjustment of the light-emitting device 10, and thus improving the dimming accuracy.

[0078] In some embodiments, positioning the second fixing device 50 between the locking plate 301 and the rod 100 may include: injecting adhesive around the rod 100 into the locking hole 3011 to fill the gap between the locking hole 3011 and the rod 100; and curing the injected adhesive.

[0079] In some embodiments, injecting adhesive around the rod 100 into the locking hole 3011 may include injecting an ultraviolet-curable adhesive into the locking hole 3011, and curing the injected adhesive may include curing the adhesive with ultraviolet light. Preferably, before injecting adhesive around the rod 100 into the locking hole 3011, the screw 3021 is screwed such that the light-emitting device 10 cannot move relative to the mounting member 20 in either the actuated or non-actuated state of the rod 100; and after the injected adhesive has cured, the screw 3021 is screwed to provide the tightening torque to the light-emitting device 10 and the mounting member 20 (i.e., screwing the screw 3021 in the opposite direction). In this way, the adhesive forming the second fixing device 50 can be provided while the light-emitting device 10 is completely fixed to the mounting member 20, ensuring close contact between the components during adhesive application, thereby ensuring the quality of adhesive application.

[0080] In the context of this disclosure, the use of directional terms such as “front,” “back,” “left,” “right,” “up,” “down,” “far,” and “near” is for descriptive purposes only and should not be considered limiting. Although this disclosure has been described with reference to exemplary embodiments, it should be understood that this disclosure is not limited to the specific embodiments described and shown herein. Various changes to the exemplary embodiments can be made by those skilled in the art without departing from the scope defined by the claims of this disclosure.

[0081] The features mentioned and / or shown in the foregoing description of exemplary embodiments of this disclosure may be combined in the same or similar manner with one or more other embodiments, combined with features in other embodiments, or substituted for corresponding features in other embodiments. Such combinations or substitutions should also be considered as including within the scope of protection of this disclosure.

[0082] Industrial applicability

[0083] This disclosure provides a light-emitting device for a vehicle lamp. The light-emitting device may include: a light-emitting unit configured to emit illumination light, the light-emitting unit including a rod extending forward in a longitudinal direction from an end face of the light-emitting unit, and a screw mounting hole provided on the light-emitting unit; a mounting member disposed in front of the light-emitting unit and including a mounting hole for the rod to extend through, the mounting member being configured as a fastener for fixing to the vehicle lamp; and a locking device, the locking device including a locking plate and a spring bolt, the spring bolt including a screw and a bolt head, the locking plate disposed in front of the mounting member in the longitudinal direction and including a locking hole for the rod to extend through, the rod extending through the mounting hole and the locking hole and protruding forward beyond the locking plate, and the end of the rod protruding forward beyond the locking plate being actuable, a screw guide provided at a position on the locking plate different from the locking hole. A screw can be inserted longitudinally through a screw guide hole into the mounting member and screwed into the screw mounting hole. The screw head can abut against the front surface of the locking plate. The tightening torque provided by the spring bolt allows the light-emitting device to be fixed relative to the mounting member in the non-actuated state, and to move relative to the mounting member in the lateral and / or vertical direction in the actuated state, thereby allowing the position of the light-emitting device to be adjusted in the lateral and / or vertical direction. The locking plate can be configured such that after the position of the light-emitting device is adjusted to the position in the lateral and / or vertical direction, the locking plate is fixed to the mounting member. The locking plate can include a rib extending longitudinally forward from the front surface of the locking plate, defining a receiving cavity in which a first fixing device can be provided. The first fixing device is an adhesive formed by injecting adhesive into the receiving cavity and curing the injected adhesive. In this way, the light-emitting device is completely fixed without the need for secondary tightening of the spring bolt. Therefore, the relative displacement between the components of the light-emitting device after adjustment is avoided due to the secondary tightening of the spring bolts, thus preventing changes in the light pattern of the vehicle lights caused by such relative displacement, and consequently, a deterioration in lighting performance. Furthermore, by setting up the first fixing device, the bonding area between the rod and the locking plate can be increased, thereby increasing the bonding force between the rod and the locking plate, making the fixation more reliable.

[0084] Furthermore, it is understood that the light-emitting devices and assembly methods thereof, vehicle lamps and vehicles provided in this disclosure are reproducible and can be used in a variety of industrial applications.
