Description
Technical Field
The invention relates to the field of automobile lamps, in particular to a folding type hidden floor illuminating lamp combined with an automobile side mark.
Background
With the vigorous development of the automobile industry, the modeling of automobiles becomes one of the main selling points of the competition of various automobile enterprises, and the atmosphere lamp is the hot product of the current modeling.
The atmosphere lamp outside the car produces the pattern through throwing light to the subaerial of door below to promote user's visual perception. The atmosphere lamp outside the vehicle usually comprises a carpet lamp, a marker lamp (namely LOGO lamp) and the like, is usually used on high-end luxury vehicle types in the past, is also assembled on some middle-end vehicle types along with the continuous aggravation of competition among vehicle enterprises, is more likely to become the standard matching of the vehicle in the future, and has great development potential. LOGO is an abbreviation of LOGO or trademark, and automobile LOGO plays a role in identifying and popularizing automobile manufacturers.
At present, the defect that scheme self exists about arranging of this kind of car atmosphere lamp, and be difficult to satisfy the user demand of two kinds of carpet lamps and LOGO lamp simultaneously, restricted the development of car atmosphere lamp.
Carpet lamp and LOGO lamp all have requirements to the scope, definition, luminance etc. of formation of image, and both require respectively to be different.
Fig. 1 shows the effect of a carpet light of the prior art arranged on a chassis, as shown in fig. 1, which is often arranged under the chassis or on a door sill in the prior art due to the large required imaging area and the large volume of the lamp head.
Because the LOGO lamp has higher requirements on imaging definition, the axis of a light cone in the prior art is nearly vertical to the ground, and the LOGO lamp is usually arranged inside a vehicle door or integrated in a rearview mirror.
Both of the above-described arrangements of atmosphere lamps have drawbacks.
The carpet light arrangement on the chassis has the following disadvantages:
1) the carpet lamp is easy to be stained, and the carpet lamp is difficult to clean after being stained;
2) the carpet lamp is low in position and is easily hit by the ground stone, and the property loss is caused by the damage of the lamp holder;
3) the position of the carpet lamp is overlapped with that of the jack, and if a user does not operate properly, the lamp head is easily damaged to cause loss;
4) the carpet lamp is low in position and easy to wade to cause loss;
5) the distance is nearer to ground, in order to guarantee sufficient irradiation area, has restricted the contained angle on carpet lamp and ground, has influenced the definition of formation of image, leads to the length that the pattern can clearly form an image and is less than the one third of pattern full length.
In order to obtain a better visual effect, the projection shape of the existing carpet lamp is mostly 'angel wing' as shown in fig. 1, even if the front and back directions of the vehicle are distorted, the carpet lamp still can present a better effect, but if all automobile models adopt similar patterns, the styles of the automobile lamps cannot be revealed, and the aesthetic fatigue of users is easily caused.
Fig. 2a shows the effect of a prior art carpet lamp arranged on a door sill, and fig. 2b is a partially enlarged view of the box portion of fig. 2a, and as shown in fig. 2a and 2b, a lamp head 11 is mounted in the door sill of a vehicle and irradiates the ground to form a light channel 12.
The carpet lamp is arranged in the threshold, a large space needs to be reserved inside the vehicle threshold, but most vehicles are not provided with the plastic threshold at present, so that the application scene of the arrangement scheme is greatly limited.
At present, aiming at the defects of the carpet lamp arrangement scheme, the following compensation measures are provided:
1) a cleaning water gun is added beside the lamp holder to solve the problem of fouling;
2) the problem of distortion of an imaging pattern is solved by adopting a mode of combining a plurality of atmosphere lamps for imaging.
However, none of the above-mentioned compensation measures fundamentally solves the technical problems that the carpet lamp is easily damaged by the jack, the imaging effect is poor, and the carpet lamp is easily stained and damaged.
The defects existing when the LOGO lamp is arranged inside the vehicle door are as follows:
1) the interior space of the vehicle door is compact, so that the requirement on the size of the LOGO lamp is high;
2) only when the door is opened at a large angle, the imaging pattern can be completely displayed, and the light is completely shielded in the scenes that a user is about to get on the vehicle and the door of the vehicle is closed by the user.
The LOGO lamp is integrated in the rearview mirror and has the following defects:
1) the volume of the rearview mirror is increased, the wind resistance is increased, and the fuel economy is reduced;
2) rear view mirrors belong to the vulnerable parts of vehicles, in which too many elements are integrated, which will increase the costs of the later maintenance for the user.
In addition, the scheme of above-mentioned all carpet lamps and LOGO lamp is except self defect, all can't satisfy the demand of arranging of LOGO lamp and carpet lamp simultaneously, and the commonality is relatively poor.

And the rotating mechanism controls the rotating motion of the lamp cap module to ensure that the lamp cap module is delivered to a specified opening angle in a normal state and at a working position so as to meet the imaging effect. Meanwhile, the rotating mechanism is also used for reliably closing the lamp cap module in a furled mode when the rotating mechanism is in a non-working position.
In the embodiment shown in fig. 5 and 6, the rotation mechanism includes a motor 201, a control module, a gear set 203, a return spring 204, a rotating shaft 205, a rotating bracket 206, an exterior side sign 207, and a motor housing 208.
The return spring 204 is mounted on the rotating shaft 205, and provides a return force for inward rotation of the lamp head module 100 and the exterior side mark 207.
The motor 201 provides power for rotating the rotating shaft 205 inward and outward.
The control module controls the rotation angle and the working torque of the motor 201.
And the control module comprises a Hall sensor 202 for detecting the working torque of the motor 201.
The gear set 203 transmits the torque of the motor 201 to the rotation shaft 205.
The rotating bracket 206 is fixedly connected with the lamp head module 100 and the outer decoration side mark 207, and rotates inwards or outwards under the control of the rotating shaft 205.
The rotation shaft 205 controls inward and outward rotation of the rotation bracket 206.
The motor housing 208 encapsulates the motor 201 and the control module into a whole.
The rotation center of the rotating mechanism is the core of the motion track of the whole rotating mechanism. The center of rotation is determined by the mounting position of the rotating shaft 205.
Fig. 13 discloses a sectional view of the rotating mechanism according to the embodiment of the present invention, the mounting position of the rotating shaft 205 is as shown in fig. 13, and the rotating shaft 205 is mounted in a protruding portion at the upper end of the housing 300.
After the installation is completed, the height of the rotation shaft 205 is higher than the upper opening of the body fender 400. Preferably, the height of the rotation shaft 205 is not less than 10mm higher than the upper opening of the body fender 400.
After the installation, rotation axis 205 is located the opening upper portion of automobile body fender 400, and the higher mounted position of rotation axis 205 can leave bigger space for the lamp body, also can completely cut off the rainwater simultaneously, avoids the oxidation.
From a transverse perspective of the vehicle body, i.e., from the cross-sectional perspective of fig. 13, the mounting location of the pivot axis 205 is closer to the inside of the body fender 400 than the integrated center of mass 209 of the exterior side rail 207, thereby ensuring that the exterior side rail 207 remains closed under the influence of gravity and the return spring 204 when in the inoperative position. The integrated mass center 209 of the exterior side mark 207 is a mass center corresponding to the mass of the lamp holder module 100 integrated with the exterior side mark 207 and the rotating bracket 206.
In the working position, the rotating mechanism rotates the lamp cap module outwards to an opening angle, and the external decoration side mark is synchronously opened. Next, as shown in fig. 13, the minimum operating torque of the motor 201 when the outer cover side mark 207 is opened will be described. The dotted line in fig. 13 shows that the lamp head module 100 and the exterior side sign 207 are turned on by rotating outward.
Considering that the change of the angular velocity is small when the exterior side mark 207 moves, the angular acceleration is ignored.
When the motor 201 is supposed to provide a moment M when the exterior side mark 207 is opened, and when the opening angle of the exterior side mark 207 is x, the applied spring moment is: k (gamma)1+ x), the gravitational moment experienced is: mgd1sin (x). Wherein m is the mass of the lamp holder module 100 integrated with the outer decoration side mark 207 and the rotating bracket 206, d1Is the distance between the integrated centroid 209 of the outer trim side mark 207 and the rotation axis 205, g is the gravitational acceleration, γ1K is the spring rate of the return spring 204, which is the difference between the pre-tensioned angle of the return spring 204 in the inoperative position and the angle in the free state.
The operating torque M required to be provided by the motor 201 needs to satisfy the following condition:
M＞mgd1sin(x)+k(γ1+x)
since the maximum opening angle when the exterior trim side mark 207 is opened is γ, γ satisfies the following relationship:
wherein, w1For the furthest distance, w, of the imaged pattern from the lamp head module in the longitudinal direction of the vehicle body2The distance between the imaging pattern and the lamp holder module in the longitudinal direction of the vehicle body is the shortest; l1For the greatest distance of the imaged pattern from the lamp base module in the transverse direction of the vehicle body,/2The minimum distance between the imaging pattern and the lamp holder module in the transverse direction of the vehicle body is h, the height of the lamp holder module from the ground is h, beta is a backward rotation angle, gamma is an outward rotation angle, and alpha is an included angle between a light cone generatrix and a light cone axis, wherein the light cone generatrix is shot to the ground.
Therefore, to satisfy the operation requirement, the operation torque M when the motor 201 is turned on needs to satisfy the following condition:
therefore, in the operating position, the exterior side mark 207 is turned on, and the minimum operating torque M1 at which the motor 201 satisfies the on condition is:
wherein m is the quality of the integrated lamp cap module, the external decoration side mark and the rotating bracket, d1Distance between the integrated center of mass of the outer decoration side mark and the rotating shaft, g is gravity acceleration, l2Is the closest distance between the imaging pattern and the lamp holder module in the transverse direction of the vehicle body, h is the height of the lamp holder module from the ground, and gamma1K is the spring rate of the return spring 204, which is the difference between the angle of the return spring in the rest position and the angle in the free state.
In the non-working position, the rotating mechanism rotates the lamp cap module inwards to a furling angle, and the outer decoration side mark is furled synchronously and is flush with the vehicle body fender. In order to prevent the situation that the motor is burnt out due to the forced opening of the outer decoration side mark after the outer decoration side mark is subjected to an overlarge external load, the maximum working torque of the selected motor is set as a safe torque, and when the working torque of the motor exceeds the safe torque, the power supply of the motor is cut off, so that the outer decoration side mark returns to the original position.
Next, as shown in fig. 13, the maximum operating torque of the motor 201 when the outer cover side mark 207 is closed will be described.
The working torque when the outer decoration side mark 207 is closed is provided by the motor 201, the return spring 204 and gravity together. The corresponding anti-pinch function is prevented from being forcibly opened by the side mark of the exterior trim, and the maximum required pinch force is n. Preferably, the clamping force does not exceed 100N.
The operating torque M required to be provided by the motor 201 needs to satisfy the following condition:
therefore, when the outer decoration side mark 207 is closed, the maximum operating torque M2 at which the motor 201 satisfies the condition is:
wherein m is the quality of the integrated lamp cap module, the external decoration side mark and the rotating bracket, d2The distance between the farthest position of the outer decoration side mark and the rotating shaft, g is the gravity acceleration, l1For the greatest distance of the imaged pattern from the lamp base module in the transverse direction of the vehicle body,/2Is the closest distance between the imaging pattern and the lamp holder module in the transverse direction of the vehicle body, h is the height of the lamp holder module from the ground, and gamma1The difference between the angle of the return spring at the non-working position and the angle in the free state is shown as k, the spring stiffness of the return spring is shown as k, and the maximum clamping force for preventing the outer decoration side mark from being forcibly opened is shown as n.
The moment provided by the return spring 204 is such that the outer trim side mark 207 does not open due to vibration.
Once the motor is fed with water, the function of the motor is directly disabled, and elements cannot normally operate. In order to avoid water inflow of the motor, the following waterproof design is adopted.
The motor and control module comprises a hall sensor, and the hall sensor is arranged above the shell and fixed outside the shell, and the specific installation position is shown in fig. 5 and 14.
Fig. 14 shows a schematic view of an opening of a power supply harness according to an embodiment of the invention, as shown in fig. 14, after the installation is completed, the bottom of the motor 201 is higher than the opening height of the vehicle body fender, and rainwater is isolated.

Around casing 300, be equipped with round rubber circle 302, after the installation, the opening of automobile body fender is hugged closely to rubber circle 302, and is sealed with the opening matching of automobile body fender, has stopped ponding from the feasible of gap inflow motor 201. Preferably, the thickness of the rubber ring is 1 mm.
Because the lamp holder module adopts the convertible design, the length of the power supply pencil of lamp holder module needs to satisfy certain condition.
The position of the lamp head module is determined by the required imaging effect, so the position of the wiring hole of the power supply wiring harness is determined according to the position of the lamp head module.
Since the solution of the invention only considers the rotation of the rotation axis 205. Therefore, the position of the wiring hole should be as close to the rotation axis of the top end as possible, and the closer the distance from the rotation axis, the smaller the required length variation of the lamp head module 100 during the movement.
As shown in fig. 14, the power supply harness 105 of the base module 100 is close to the rotation axis at the opening position of the housing 300, so that the length variation of the power supply harness 105 during the movement of the base module 100 is greatly reduced.
Considering the influence of the bending stress of the power feeding harness 105 itself and the expansion and contraction with heat, the length of the power feeding harness 105 is increased appropriately, and a certain margin is required. The length of power supply harness 105 must not be too long or too short.
If the power supply harness 105 is too short, normal outward rotational opening of the mechanisms of the lamp head module 100, the exterior side markings 207, etc. is affected. If the power supply harness 105 is too long, the normal inward rotation and closing of the lamp head module 100, the exterior side mark 207 and other mechanisms are affected.
The length of power supply harness 105 is between a first predetermined length and a second predetermined length.
The first preset length is a length corresponding to an opening angle to which the exterior trim side mark 207 is not influenced to rotate outward, and the exterior trim side mark can be turned outward to a minimum working angle and normally works at the preset length.
The second preset length is a corresponding length that affects the exterior side emblem to rotate inward to the furled angle, at which the exterior side emblem 207 can be turned inward to furled closed without being affected by the length of the power supply harness 105.
