Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the invention, the condition that a driver does not notice the opening and closing of the rear window of the automobile during driving (probably because a rear passenger forgets to close the opened window before getting off the automobile) is considered. Thus, when rain suddenly occurs during driving, the rain easily drifts into the window from the rear row. Of course, if the driver suddenly rains while driving the vehicle and the windows of the main driving seat are opened, the driver may observe the open/closed states of all the windows. However, when the windows of the main driving position are closed, the driver may not realize that the rear window is closed after the driver suddenly rains in the driving process, and the rear seat of the automobile can be exposed to rain. In order to solve the above problems, the present inventors have purposefully designed a method for controlling a rear window of an automobile. On one hand, the control of only the rear window and not the front window or the skylight aims to prevent the attention of a driver from being dispersed when the front window is controlled (the front window or the skylight of the automobile suddenly rises without accident, so that the sight of the driver is transferred to the window position, thereby causing the driver to be distracted), and generating danger; on the other hand, even if the front window or the skylight is opened and rains suddenly in the driving process, the driver can control the opening and closing of the window automatically; on the other hand, when only the rear window is controlled, the control process is relatively hidden, the attention of a driver in the driving process cannot be dispersed, and traffic accidents are avoided. In the rear window control method, rain data is acquired (whether the vehicle is rained or not or the size of the rain can be judged according to the opening and closing state of a windscreen wiper and the water flow of a water guide groove below a front window of the vehicle), when the rain is found, the opening and closing state of the rear window is detected, if the rear window is opened, the rear window is controlled to ascend (the rear window can ascend to be closed or ascend for a short distance when the rain is small), in addition, in order to reduce the noise generated when the rear window is closed, the distraction of a driver in the driving process is prevented (when the rear window suddenly makes a sound in the driving process of the vehicle, the distraction of the driver is caused), the vehicle window is ascended at an extremely low speed (which is far lower than the ascending speed of a conventional vehicle window), and particularly 1CM per second. Of course, the present invention also takes into account the possibility that the driver may deliberately open the rear window for ventilation, so that the window is not directly closed when being controlled, but is raised a short distance when the amount of rain is small, so that the window can perform the ventilation function and also prevent large rain from drifting into the vehicle.

In view of the above-mentioned control method, the inventor of the present invention considers that when the rear window of the conventional vehicle rises, friction is generated between the rear window and the weather strip, which causes a loud noise in the process of rising the rear window, and thus the attention of the driver is easily dispersed in the process of automatically rising the rear window. In view of this, the present invention further improves the hardware structure of the vehicle, and thus provides a vehicle drive assembly and a control method.

Referring to fig. 1 to 4, there is provided an automobile drive assembly for driving only the up-down of the rear window 100 of an automobile (which is explained above for driving only the rear window 100 of an automobile and will not be described here in detail). Specifically, the vehicle drive assembly includes a first drive device, a second drive device, and a seal assembly.

The first driving means is used to independently drive the rear window 100 to ascend and descend, which may be considered as a conventional driving means in the prior art.

The second driving means is for independently driving the rear window 100 to ascend. The second driving means may be regarded as a driving means added independently in the present application, and is dedicated to driving the rear window 100 to ascend.

The sealing assembly includes a first sealing strip 210 and a second sealing strip 220, the first sealing strip 210 and the second sealing strip 220 are respectively disposed on two sides of the rear window 100, and the first sealing strip 210 and the second sealing strip 220 have a first working position respectively abutting against the rear window 100 and a second working position respectively spaced from the rear window 100. The position of the existing sealing strip is unchanged, and the sealing strip is abutted against the window of the automobile so as to prevent water on the window from flowing down to the interior of the automobile door. This embodiment allows both the seal strips to be moved to positions separated from the rear window 100. Before the process that the second driving device drives the sealing assembly to ascend, the first sealing strip 210 and the second sealing strip 220 are driven to move from the first working position to the second working position respectively. Of course, in order to match the ascent of the window, the first driving device needs to be correspondingly passively rotated while the rear window 100 ascends.

In the automobile driving assembly in this embodiment, on the first hand, when the second driving device drives the rear window 100 to ascend, the first sealing strip 210 and the second sealing strip 220 are driven by the second driving device to be separated from the rear window 100, so that noise is not generated due to friction between the automobile rear window 100 and the first sealing strip 210 and the second sealing strip 220 in the ascending process, and therefore, the attention of a driver is not dispersed in the automatic control ascending process of the automobile rear window 100, and the safety performance is improved. In the second aspect, a set of driving device (i.e. a second driving device) is added to drive the rear window 100 to ascend, so that the second driving device can drive the rear window 100 to ascend at a lower speed, and noise is further reduced. If the original driving device is used to drive the rear window 100, the original driving device needs two driving rates, which is likely to cause driving disorder, and meanwhile, the existing rope driving structure is difficult to drive the first sealing strip 210 and the second sealing strip 220 to be separated from the rear window 100 while driving the window to ascend. Specifically, the second driving device may include two driving motors, the two driving motors respectively drive the rear window 100 to ascend and the weather strip to move, and the second driving device may also include one driving motor respectively drive the rear window 100 to ascend and the weather strip to move through two transmission devices).

Further, the rear window 100 has an upper limit position and a lower limit position, and the driving device is configured to drive the rear window 100 to drive the first sealing strip 210 and the second sealing strip 220 to move from the second working position to the first working position after the upper limit position. That is, the first weather strip 210 and the second weather strip 220 are driven to return to the position abutting against the rear window 100 when the rear window 100 is driven to the upper limit position, thereby achieving the sealing effect thereof.

Further, both ends of the first sealing strip 210 and the second sealing strip 220 extend out of the rear window 100, and both ends of the first sealing strip 210 and the second sealing strip 220 are connected in a sliding manner, so that the first sealing strip 210 and the second sealing strip 220 can slide in a direction approaching or separating from each other. Also, the front ends of the two weatherstrips are connected and can slide in a direction toward or away from each other, and the rear ends of the two weatherstrips are connected and can slide in a direction toward or away from each other. One side of the first sealing strip 210 departing from the second sealing strip 220 is connected with a first magnetic strip (or the inside of the first sealing strip 210 is provided with a through hole, and the first magnetic strip 310 is arranged in the through hole), and one side of the second sealing strip 220 departing from the first sealing strip 210 is connected with a second magnetic strip 320. The second driving device is connected to the first magnetic strip 310 to drive the first magnetic strip 310 to rotate. In this way, the first magnetic strip 310 can be driven to rotate so as to attract and repel the first magnetic strip 310 and the second magnetic strip 320, and thus the first sealing strip 210 and the second sealing strip 220 can be moved closer to and away from each other. The first magnetic strip 310 may be a flexible strip so that it can be conveniently driven.

In one embodiment, referring to fig. 3 to 4, the first sealing strip 210 and the second sealing strip 220 may be both flexible strips, and the front end of the first sealing strip 210 and the front end of the second sealing strip 220 extend out of the rear window 100 and are fixedly connected, the rear end of the first sealing strip 210 and the rear end of the second sealing strip 220 extend out of the rear window 100 and are fixedly connected, the first sealing strip 210 is connected to the first magnetic strip 310, and the second sealing strip 220 is connected to the second magnetic strip 320. The first magnetic strip 310 is disposed through the first sealing strip 210, and the first sealing strip 210 and the second sealing strip 220 are driven to move close to or away from the rear window 100 by driving the first magnetic strip 310 to rotate.

Further, the second driving device comprises a first motor and a speed reducing device, the speed reducing assembly is meshed with the first motor, the edge of the front end of the rear window 100 is provided with a strip-shaped tooth 120, the strip-shaped tooth 120 is meshed with the speed reducing device, the first motor is configured to control the upper body of the rear window 100 through the speed reducing assembly, and the rising speed of the rear window 100 is 0.5 cm/s to 1.5 cm/s. In this way, the second drive means can raise the rear window 100 at a slower rate, thereby reducing noise.

Further, rear window 100 includes window body and tooth body, and the front end edge of window body is provided with vertical arrangement's mounting groove 110 (mounting groove 110 can be for the clearance of doubling position in the middle of two pieces of glass of rear window 100), and the material of tooth body is the rubber material, and the tooth body inlays in mounting groove 110, and the tooth body includes bar tooth 120. This can further reduce noise when driving the rear window 100.

Referring to fig. 5, the second aspect of the present application further provides a control method for controlling a rear window 100 of an automobile by using any one of the automobile drive assemblies, including:

s101: acquiring the rain state of an area where an automobile is located in the driving process of the automobile, wherein the rain state comprises rain and no rain;

s102: when the raining state is raining, acquiring the open-close state of the rear window 100 of the automobile;

s103: when the rear window 100 of the automobile is opened, the second driving device drives the first sealing strip 210 and the second sealing strip 220 to move from the first position to the second position, then the second driving device drives the rear window 100 of the automobile to ascend to the preset position, and then the second driving device drives the first sealing strip 210 and the second sealing strip 220 to move from the second position to the first position.

Further, when the raining state is raining, the degree of raining is acquired, and the height of the rear window 100 is controlled according to the degree of raining.

Further, a first rising height and a second rising height are preset, the first rising height being a height at which the rear window 100 rises to be flush with the lower end of the window weather shield, and the second rising height being a maximum rising height of the rear window 100. The degree of rain is classified into light rain and heavy rain, and when the degree of rain is light rain, the second driving device drives the rear window 100 of the vehicle to rise to the first rising height, and when the degree of rain is heavy rain, the second driving device drives the rear window 100 of the vehicle to rise to the second rising height.

Further, when the raining state is raining and the rear window 100 is opened, the opening state of the front window of the automobile is acquired, and if the front window is opened, the rear window 100 is not controlled to ascend.

Further, when the raining state is raining and the rear window 100 is opened, acquiring the opening state of the front window of the automobile;

if the front window is opened, acquiring a control signal of a vehicle window control button in a first preset time period before the current time and a control signal of the vehicle window control button in a second preset time period after the current time;

if the front window is driven to rise within a first preset time period before the current time and a preset time period after the current time, a control program for controlling the rear window 100 to rise is executed.

The following is the basic principle of the control method in a specific embodiment:

during the running process of the vehicle, the rain state is monitored (the rain state can be monitored according to a windscreen wiper switch or the water flow of a water guide groove below the windshield of the vehicle), and after rain is found, the rain level is monitored (the rain level can be monitored according to the gear of the windscreen wiper or the water flow of the water guide groove below the windshield of the vehicle). The rain grade is divided into two grades of heavy rain and light rain. Then, the opening state of the front window of the automobile is detected, when the front window is opened, the preset time (specifically, one minute to two minutes) before the current time and the adjustment state of the window (specifically, half minute to one minute) after the current time are obtained, if the driver does not adjust the window within the time, the rear window 100 is not controlled subsequently, if the driver adjusts the front window, the opening state of the rear window 100 is obtained, and if the rear window 100 is opened, the rear window 100 is driven to ascend by using a second driving device (the rear window 100 is driven to ascend to the lower end flush position of the rain shield when the rain is light, and the rear window 100 is driven to ascend to the upper limit position when the rain is heavy).
