When the electric sunshade is unfolded and folded, the curtain is driven and unfolded in a constant speed manner. When the rod is fixed at the end of the curtain, the rod is displaced to the bottom dead center. Often, due to inertia, it directly hits the components of the pedestal part, and the abnormal sound of the mechanism collision is generated, which in turn interferes with the passengers in the car. Because the sound insulation effect of the car body of some advanced cars is very good, the collision noise is in the quiet car phase. It is even more awkward. In addition, the current electronic control module design of such electric sunshade is mostly designed for the ambient temperature of the general tropical or subtropical region, so when the electric sunshade is installed in the cold zone, the car is driven. This is because the operating current required for the electronic components of the electronic control module is different from that in the tropical/subtropical region, and abnormal operation or unusable operation occurs. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a curtain cushioning device which can reduce the collision noise during the operation of the sunshade. Another object of the present invention is to provide a curtain cushioning device that can change the operating current in accordance with the ambient temperature. 201037143 Thus, the curtain cushioning device of the sunshade of the present invention comprises: a motor for controlling a spreading mechanism to unfold or close the curtain, and can be respectively pressed and activated and respectively representing the function of the unfolding curtain and collapsing One of the curtain function unfolding switch and a folding switch, the curtain buffer device comprises a switch judging unit connected to the unfolding switch and the retracting switch, a switch state recording unit connected to the switch judging unit, and a motor The motor control unit of the signal connection and a signal are connected to the micro-processing unit between the switch judging unit, the switch state record sheet 7L and the motor control unit. The switch determining unit can determine which switch is activated to output a pair of functions that should be switched, and the switch state recording unit can record a function message corresponding to the function of the switch represented by the previous start signal. The motor control unit can be driven to be enabled by the microprocessor unit to output a deceleration signal for driving the motor to the final 13⁄4 # of the curtain to gradually decelerate to a stop. The microprocessor unit 7L can drive the motor control unit when it is analyzed that the function of the switch represented by the activation signal is different from the function represented by the function message. The utility model has the advantages that the motor control unit can control the motor rotation speed in a deceleration manner, and the curtain can be gradually decelerated to a completely stopped design in the final stage of the folding, thereby eliminating the collision between the curtain and the exhibition mechanism and other components. Different from s, it can greatly reduce the degree of interference to the passengers in the car when the sunshade is used. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. 201037143 As shown in FIG. 1 and 2, a preferred embodiment of a curtain cushioning device for a sunshade according to the present invention is suitable for being mounted on a sunshade and electrically connected to a power supply i, which can be used to control the sunshade. The speed of unfolding and folding of the curtain curtain comprises a display mechanism (not shown) for driving the curtain to be unfolded and collapsed, and a motor for driving the display mechanism. The curtain opening function and the folding curtain function unfolding switch 1〇2 and a folding switch 1〇3, and a reverse switch 104 which can be activated when the vehicle is engaged to the reverse gear and represent the folding curtain function. The curtain buffer device 3 includes a switch determining unit 31 connected to the switches 1〇2 to 1〇4, a switch state recording unit 32 connected to the switch determining unit 3, and a signal connected to the switch. The micro processing unit μ between the unit 3 and the curtain state determining unit 32, the motor control unit 34 connected between the microprocessor unit 33 and the motor 101, and a signal connected between the micro processing unit 33 and the motor control unit 34 The current detecting unit 35 and a signal are connected to the temperature sensing unit 36 of the micro processing unit 33. The switch determining unit 31 can output an activation signal according to the type of the switch that is activated when the expansion switch 1〇2, the folding switch 103, or the reverse switch 104 is pressed and activated. The switch state recording unit records a function message representing the function of the switch according to the switch of the last start signal being the unfolding switch 102, the closing switch 1 〇 3 or the reversing switch 丨〇 4 . The micro-processing unit 33 is driven by the start signal, and analyzes whether the function of the switch represented by the start signal and the switch function represented by the function §fL recorded by the switch state record unit 32 are the same. When the function of the function message 2010a is the same, for example, the function of the folding curtain or the unfolding of the curtain function 'is that the curtain is already in the unfolded or collapsed state, no need to be activated', the micro processing unit 33 will not drive. The motor controls unit 34 so that the curtain does not move. When the function of the start signal and the function message is different, for example, the start signal is the function of the folding curtain, and the function message is to represent the function of the curtain, which means that the state of the curtain is different from the state of the user's demand. 33 will drive the motor control unit 34 to enable, and control the horse itHH <actuate, thereby driving the display mechanism to unfold or collapse the curtain to conform to the curtain state that the user activated switch should present. The motor control unit 34 can be driven by the micro processing unit 33 to control the positive and negative rotation of the motor 101, and then the transmission enables the display mechanism to perform the function of unfolding the curtain or closing the curtain, and the motor control unit 34 During the deployment or folding of the curtain, the sequential output-driven horse 101 is gradually accelerated to an acceleration signal of a predetermined speed in an acceleration manner, and drives the motor 101 to be maintained. The constant speed signal of the sea pre-rotation speed, and the deceleration signal that drives the horse 1G1 to decelerate to the stop operation in an equal deceleration manner, wherein the acceleration signal timing is the entire expansion or collapse time of the curtain. %, the execution timing is 26°/ of the entire unfolding or folding time of the curtain. The execution sequence of ~75 0/〇76^ salt speed nickname is 76/°~_ of the entire unfolding or folding time of the curtain, and then controls the final stage of the curtain in the unfolding and folding, so that:: The side bar (not shown) can be gradually decelerated and slowly moved to the upper dead zone and the moving speed is reduced to zero when the top dead center and the bottom dead center are reached, thereby eliminating the component collision noise. In the present embodiment, the motor control unit 34 is mainly a control circuit composed of MO·201037143, and controls the effective current of the driving motor 101 by changing the working period of the switching MOSFET on and off. The speed of 1G1, but the way to adjust the horse's (8) speed is not limited to this.

The micro processing unit 33 can immediately drive the current overload or current abnormality. : The control unit 4 or the entire unit is stopped to prevent the motor ι〇 or other components from damaging the malfunction due to abnormal operation. The temperature sensing unit 36 can sense the surrounding ambient temperature and output a temperature signal to the micro processing unit 33 to drive the micro processing unit 33 to change the operating current of the entire curtain buffer device 3 according to the temperature value indicated by the temperature signal. The size and overcurrent protection overload current limit is limited to ensure that the electronic components of the entire curtain buffer device 3 can operate normally under various temperature environments. When the curtain buffer device 3 is activated, the micro processing unit 33 first adjusts the magnitude of the active current and the magnitude of the overload current according to the temperature signal of the OT sensing unit 36, and then enters a sleep state. After the field reverse switch 104, the expansion switch 1〇2 or the collapse switch 1〇3 is pressed and activated, the switch determination unit 31 outputs an activation signal to activate the micro processing unit 33. The micro processing unit 33 analyzes the startup.

Further, the motor 7 201037143 control unit 34 drives the motor 101 to drive the display mechanism to perform the function of unfolding the curtain or closing the curtain, and can be used to make the curtain unfold or receive by the motor control unit 34 In the final stage of the combination, the speed is reduced. When the curtain is deployed to the top dead center or collapsed to the bottom dead center, the speed is just reduced to zero, so the abnormal sound of the curtain or the exhibition mechanism colliding with other members can be eliminated. As shown in Fig. 3, in the process of recycling the curtain, since the recovery speed of the final stage of curtain recycling has gradually decreased, when it is recycled to the bottom dead center, the actual test does not cause the components to collide with each other. Different sound. Throughout the above, the motor control unit 34 can control the rotation speed of the motor 101 in a deceleration manner, so that the curtain can be gradually decelerated to a completely stopped design in the final stage of the folding, and the curtain and the collecting mechanism can be eliminated from colliding with other members.
