Description

一种电机式光型变换驱动装置及其光型变换方法Electric motor type optical conversion driving device and optical type conversion method thereof 技术领域Technical field
本发明涉及车灯装置，具体地，本发明涉及一种电机式光型变换驱动装置及其光型变换方法。The present invention relates to a vehicle lamp device, and in particular to a motor type optical conversion drive device and a light conversion method thereof.
背景技术Background technique
汽车照明灯具必须为行驶中的汽车提供最佳的照明效果。然而，在实际的道路交通环境下，当两辆相向行驶的汽车交会时，前照灯的强光会造成驾驶员的眩目而有发生交通事故的危险。Automotive lighting must provide the best lighting for a moving car. However, in the actual road traffic environment, when two cars traveling in opposite directions meet, the strong light of the headlights may cause the driver to be dazzled and there is a danger of a traffic accident.
对此，目前主要采取的解决方式是对汽车的前照灯等的使用进行光型变换。根据光型变换使用的不同的情况和要求，使用不同的前照灯。另一方面，现在大部分车辆前照灯都采用组合式灯具，即将前照灯、前转向灯等灯具组成一个整体使用。In this regard, the main solution currently adopted is to perform light conversion on the use of headlights and the like of automobiles. Different headlights are used depending on the different conditions and requirements used for the light type change. On the other hand, most of the vehicle headlamps now use combined luminaires, which are used for the whole of headlights, front turn signals and other luminaires.
虽然，如上所述，将前照灯、前转向灯等灯具组成一个整体使用的组合式灯具有便于拆卸、装配、清洗等优点，但也存在灯具安装空间限制所导致的问题。为此，提出了前照灯的光型变换一体化，即远、近灯使用同一光源，在行车过程中通过调节内部结构来切换光型变换的功能要求。Although, as described above, the combination lamp in which the headlights, the front turn signals, and the like are integrally formed has the advantages of being easy to disassemble, assemble, and clean, there are also problems caused by the limitation of the installation space of the lamp. For this reason, the integration of the light type of the headlights is proposed, that is, the far and near lights use the same light source, and the functional requirements of the light type conversion are switched by adjusting the internal structure during the driving process.
然而，在所述将前照灯、前转向灯等灯具组成一个整体使用的组合式灯具的场合，一旦光型变换功能不佳或失效，将损害光型变换的照明功能，从而容易引起安全及交通事故。由此可见，汽车照明灯中光型变换显得尤为重要，它将直接影响到汽车行驶的安全。However, in the case where the illuminating device such as a headlight or a front turn signal is used as a whole for a combined luminaire, if the optical conversion function is poor or fails, the light-converting illumination function is impaired, thereby easily causing safety and Traffic accident. It can be seen that the light type change in the car lighting is particularly important, and it will directly affect the safety of the car.
为此，已有人研究开发多种光型变换装置。For this reason, various light-converting devices have been researched and developed.
例如，申请号为“200720129230.3”的中国实用新型专利，公开了一种光型变换装置，其特征在于:所述的固定挡片设在反射镜体的前缘，所述的调整装置包含有电磁阀与活动挡片，所述的电磁阀是设有活动杆，用以及所述的活动挡片连接，所述的活动挡片是以枢接组件与所述的固定挡片连接，用以通过所述的枢接组件做为活动挡片的旋转轴，所述的活动挡片是延伸有与所述的活动挡片本体 呈垂直状的连接臂，用以及所述的电磁阀的活动杆连接。For example, the Chinese utility model patent with the application number "200720129230.3" discloses an optical type conversion device characterized in that the fixed blocking piece is disposed at the leading edge of the mirror body, and the adjusting device comprises electromagnetic a valve and a movable flap, wherein the solenoid valve is provided with a movable rod connected by the movable flap, and the movable flap is connected with the fixed bracket by a pivoting assembly for passing The pivoting assembly is used as a rotating shaft of the movable blocking piece, and the movable blocking piece is extended with the movable blocking body A vertical connecting arm is connected to the movable rod of the solenoid valve.
然而，根据所述实用新型专利的光型变换装置，其组件结构相对复杂，且其主要目的在于保护耗电量的减少以及温升幅度，难以达到切换灵活、结构简单的组合式功能性要求。However, according to the optical type conversion device of the utility model patent, the component structure is relatively complicated, and the main purpose thereof is to protect the power consumption from decreasing and the temperature rise range, and it is difficult to achieve a combined functional requirement of flexible switching and simple structure.
另外，驾驶员行车时,难免会出现会车和上下坡的情况。特别是汽车在夜间行驶时,相向而行的汽车灯光和上下坡时路面的反射光会影响驾驶员的视觉,如果太强就会造成驾驶员看不清前方道路,所以需要驾驶员及时地切换汽车的光型,如果切换不及时,就可能造成交通事故。因此，现代车辆广泛使用光型变换机构实现汽车的光型变换控制，电磁执行机构广泛应用于光型变换机构中。利用电磁执行机构中的电磁铁吸附和回弹的动作可以实现光型的切换，而且其动作较为可靠。In addition, when the driver is driving, it is inevitable that there will be a car and a slope. Especially when the car is driving at night, the opposite side of the car lights and the reflected light from the road when going up and down will affect the driver's vision. If it is too strong, the driver will not see the road ahead, so the driver needs to switch in time. The light type of a car may cause a traffic accident if it is not switched in time. Therefore, modern vehicles widely use light-type conversion mechanisms to realize light-type conversion control of automobiles, and electromagnetic actuators are widely used in optical-type conversion mechanisms. The light type switching can be realized by the action of the electromagnet adsorption and rebound in the electromagnetic actuator, and the action thereof is relatively reliable.
但是，在实际应用中，由于现有电磁执行机构中的电磁铁吸合和释放时会发出较大的碰撞噪音，从而引来一些用户的抱怨。在现今越来越强调用户使用舒适度的大环境下，降低电磁执行机构工作时的噪音就显得十分有必要了。此外，电磁铁在吸合和释放时会产生较强的震动，也容易引起光形抖动，并且这种震动还会造成连接松动等故障，影响光型变换机构的可靠性。However, in practical applications, since the electromagnets in the existing electromagnetic actuators are attracted and released, a large collision noise is emitted, which causes some users to complain. In today's environment where user comfort is increasingly emphasized, it is necessary to reduce the noise during the operation of the electromagnetic actuator. In addition, the electromagnet generates strong vibration when it is sucked and released, and it is also prone to cause light shape jitter, and such vibration may cause a failure such as loose connection, which affects the reliability of the optical conversion mechanism.
另外，专利申请号为“201410226360.3”、发明名称为“一种汽车前照灯的光型变换装置”公开了一种主要用于汽车氙气前照灯的光型变换装置，使用剪切式动铁芯式电磁阀，且包括：固定于反射镜上的夹持器，其特征在于，夹持器上固定有电磁吸铁，所述的电磁吸铁通过轴杆与连接衬套相连，所述连接衬套与可动遮光板相配合，所述可动遮光板相配合藉由绕旋转轴的自由转动改变其角度。In addition, the patent application number is "201410226360.3", and the invention name is "an optical type conversion device for an automobile headlight", which discloses an optical type conversion device mainly used for an automobile xenon headlamp, using a shearing type moving iron a core type solenoid valve, comprising: a holder fixed to the mirror, wherein the holder is fixed with an electromagnetic iron, and the electromagnetic iron is connected to the connecting bush through a shaft, the connection The bushing cooperates with a movable visor that cooperates to change its angle by free rotation about the axis of rotation.
然而，根据上述汽车前照灯的光型变换装置，可动遮光板绕其一侧轴支点转动，通过改变可动遮光板的角度变化，引起遮光效果的变化，其可动遮光板的角度变化带来的遮光部位的变化收到限制，影响光型变换效果；However, according to the light type conversion device of the above-described automobile headlight, the movable visor rotates around one side pivot point thereof, and changes the angle of the movable visor to change the shading effect, and the angle of the movable visor changes. The change in the shading area is limited, affecting the light-type transformation effect;
另外，根据上述汽车前照灯的光型变换装置，其限位只是单纯的一端的档块结构，只起到限位作用，无降噪效果，故工作噪音大。In addition, according to the light type conversion device of the above-mentioned automobile headlight, the limit position is only a simple one-end block structure, which only serves as a limit function and has no noise reduction effect, so the working noise is large.
如图1所示，以往使用剪切式动铁芯式电磁阀的系统的工作原理如下：As shown in Fig. 1, the working principle of the system using the shear type moving iron solenoid valve is as follows:
当驾驶员需要使用车灯远光功能时，按下光型变换拨杆，BCM(即平台化的光型变换电磁阀模组)会给电磁阀供电，线圈通电后产生电磁力，使得铁芯移动，连杆机构带动遮光板下移，实现远光功能，断电后通过弹簧力自动将电磁阀回复到初始位置。在实际应用中，由于现有电磁执行机构中的电磁铁吸合和释放时会 发出较大的碰撞噪音，从而也引来一些用户的抱怨。When the driver needs to use the high beam function of the lamp, press the light type shift lever, BCM (that is, the platformized light type conversion solenoid valve module) will supply power to the solenoid valve, and the coil will energize to generate electromagnetic force, so that the iron core Move, the linkage mechanism drives the visor down, realizing the high beam function, and automatically returns the solenoid valve to the initial position by the spring force after the power is cut off. In practical applications, due to the attraction and release of electromagnets in existing electromagnetic actuators A large collision noise is emitted, which also attracts some users' complaints.
在现今越来越强调用户使用舒适度的大环境下，降低电磁执行机构工作时的噪音就显得十分有必要了。此外，电磁铁在吸合和释放时会产生较强的震动，也容易引起光形抖动，并且这种震动还会造成连接松动等故障，影响光型变换机构的可靠性。In today's environment where user comfort is increasingly emphasized, it is necessary to reduce the noise during the operation of the electromagnetic actuator. In addition, the electromagnet generates strong vibration when it is sucked and released, and it is also prone to cause light shape jitter, and such vibration may cause a failure such as loose connection, which affects the reliability of the optical conversion mechanism.
因此，以往汽车前照灯的光型变换装置存在的问题是：光型变化过程中容易出现卡滞；扭矩输出不稳定，成本高，噪音大，兼容性不佳。Therefore, in the past, the problem of the light type conversion device of the automobile headlight is that the sticking is prone to occur during the change of the light type; the torque output is unstable, the cost is high, the noise is large, and the compatibility is poor.
发明内容Summary of the invention

The stuck in the process; through the optimized adjustment of the winding, the heat generated by the motor itself can be reduced and a sufficient torque output can be ensured. The invention is compact and simple in structure, and reduces manufacturing process cost and noise.
另外，由于克服传统光型变换装置主要应用于氙气大灯的光型变换单元，本发明适用于氙气大灯及卤素灯等场合，提升其兼容性。In addition, since the conventional optical type conversion device is mainly applied to a light conversion unit of a xenon headlight, the present invention is suitable for use in a xenon headlight and a halogen lamp to improve compatibility.
