[0002] The conventional glass lifting mechanism is used on the current vehicle, which can make the vehicle window glass rise and fall along the set track. The existing vehicle window glass lifting mechanism mainly has a rope wheel type and a fork arm type. Both of them are driven by a motor to drive a pull wire or a fork arm to drive a sliding block to slide relative to a guide rail, so as to drive the vehicle window glass to rise or fall.

DETAILED DESCRIPTION
[0033] In order to more clearly illustrate the technical solutions in the embodiments of the present disclosure or the prior art, the accompanying drawings required by the embodiments or the prior art description will be briefly introduced. Obviously, those skilled in the art can obtain other drawings according to these drawings without any creative effort.
[0034] In the following description, many specific details are set forth in order to provide a thorough understanding of the present disclosure. However, the present disclosure can be practiced in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, not all the embodiments.
[0035] The vehicle window glass lifting mechanism, vehicle door and vehicle of the present disclosure will be described in detail below through specific embodiments.
[0036] Referring to Figures 1 to 4 An embodiment of the present disclosure provides a vehicle window glass lifting mechanism, which comprises a guide rail 1 and a sliding block 2 arranged on the guide rail 1.
[0037] The first permanent magnet 21 and the second permanent magnet 22 are arranged on the sliding block 2, the first electromagnetic coil 11 and the second electromagnetic coil 12 are arranged on the guide rail 1, the first electromagnetic coil 11 and the second electromagnetic coil 12 can generate a magnetic field when energized, and the first electromagnetic coil 11 and the second electromagnetic coil 12 are arranged along the extension direction of the guide rail 1.
[0038] Specifically, the first electromagnetic coil 11 is arranged corresponding to the first permanent magnet 21, when the first electromagnetic coil 11 is energized, the first magnetic force is generated between the first electromagnetic coil 11 and the first permanent magnet 21, the first magnetic force pushes the sliding block 2 to slide along the extension direction of the guide rail 1, and further drives the vehicle window glass to move along the extension direction of the guide rail 1, so that the vehicle window glass can be lifted or lowered.
[0039] The second electromagnetic coil 12 abuts against the second permanent magnet 22, when the second electromagnetic coil 12 is energized, the second magnetic force is generated between the second electromagnetic coil 12 and the second permanent magnet 22, the second magnetic force drives the second permanent magnet 22 to move away from the second electromagnetic coil 12.
[0040] It can be understood that when the second electromagnetic coil 12 is energized, the second magnetic force can separate the second electromagnetic coil 12 and the second permanent magnet 22, at this time, under the action of the first magnetic force, the first permanent magnet 21 can be driven to slide, and further drive the sliding block 2 to slide relative to the guide rail 1, when the second electromagnetic coil 12 is de-energized, the second electromagnetic coil 12 and the second permanent magnet 22 abut against each other again, the sliding block 2 can maintain the current position on the guide rail 1, and further make the vehicle window glass maintain the current position, and the first electromagnetic coil 11 and the second electromagnetic coil 12 are arranged along the extension direction of the guide rail 1, so that the second permanent magnet 22 can abut against the second electromagnetic coil 12 at any position of the second electromagnetic coil 12 when the second electromagnetic coil 12 is de-energized, without the need of additional motor or other mechanism, the lifting and braking of the vehicle window glass can be completed, the structure is compact, the space utilization is improved, and the user's riding experience is improved.
[0041] In specific implementation, the second magnetic force is repulsive force, that is, the second permanent magnet 22 and the second electromagnetic coil 12 are arranged opposite to each other, so that the second permanent magnet 22 and the second electromagnetic coil 12 can be separated. The first magnetic force is a pushing force that pushes the first permanent magnet 21 to slide away from the first electromagnetic coil 11, and further pushes the sliding block 2 to slide away from the guide rail 1, so as to drive the vehicle window glass to rise and fall through the sliding block 2.
[0042] In some embodiments, the second permanent magnet 22 is connected to the slider 2 via an elastic element 3. The elastic element 3 generates an elastic force, causing the second electromagnetic coil 12 to elastically abut against the second permanent magnet 22 under the action of the elastic element 3. The elastic force is opposite in direction to the second magnetic force. When the second electromagnetic coil 12 is energized, it can resist the elastic force, thereby separating the second electromagnetic coil 12 and the second permanent magnet 22. Specifically, the elastic element 3 can be a spring. The elastic element 3 can generate an elastic force to elastically press the second permanent magnet 22 onto the second electromagnetic coil 12. Under the action of the second magnetic force, the elastic element 3 can also be compressed to separate the second permanent magnet 22 and the second electromagnetic coil 12. When the second magnetic force compresses the elastic element 3, an elastic force will still be generated on the elastic element 3.
[0043] Of course, the elastic element 3 can also be other structural elements. This disclosure does not limit this, as long as it can elastically abut against the second permanent magnet 22 on the second electromagnetic coil 12 and can be compressed under the action of the second magnetic force, thereby separating the second permanent magnet 22 and the second electromagnetic coil 12.
[0044] In specific implementation, second electromagnetic coils 12 are symmetrically arranged on both sides of the guide rail 1. Second permanent magnets 22 and elastic elements 3 are arranged on the slider 2 at positions corresponding to the second electromagnetic coils 12. The elastic forces on both sides of the guide rail 1 are opposite in direction and equal in magnitude, so that the guide rail 1 is balanced in the horizontal direction when the first electromagnetic coil 11 and the second electromagnetic coil 12 are de-energized. It can be understood that when the first electromagnetic coil 11 and the second electromagnetic coil 12 are de-energized, the elastic elements 3 on both sides of the guide rail 1 can elastically abut the second electromagnetic coil 12 against the corresponding second permanent magnet 22, so that both sides of the guide rail 1 can receive elastic forces from the elastic elements 3. Since the elastic forces on both sides of the guide rail 1 are opposite in direction and equal in magnitude, the guide rail 1 is balanced, and can remain in the middle position of the slider 2, preventing relative displacement between the slider 2 and the guide rail 1. It can be understood that when the guide rail 1 is balanced, the slider 2 is also balanced.
[0045] Reference Figure 1 and Figure 2 As shown, the slider 2 is positioned at least outside the guide rail 1 at positions corresponding to all the second electromagnetic coils 12. This arrangement allows the slider 2 to slide relative to the guide rail 1 to raise and lower the window glass, while also preventing the slider 2 or the guide rail 1 from dislodging, thus ensuring the structural stability of the window glass lifting mechanism.
[0046] In specific implementation, there are an even number of second electromagnetic coils 12, symmetrically arranged in pairs on opposite sides of the guide rail 1. There are also an even number of second permanent magnets 22, each corresponding to one of the second electromagnetic coils 12, with the magnetic force of corresponding pairs of second permanent magnets 22 being the same. When the second electromagnetic coils 12 are energized, a second magnetic force of the same magnitude is generated on both sides of the guide rail 1. It can be understood that the equal number and corresponding arrangement of the second electromagnetic coils 12 and second permanent magnets 22 form a braking assembly. The guide rail 1 is symmetrically arranged with braking assemblies on both sides. These braking assemblies can apply the same elastic force to the guide rail 1 through the elastic element 3, ensuring the guide rail 1 remains stable and preventing wobbling. That is, when the first electromagnetic coil 11 and the second electromagnetic coil 12 are de-energized, the elastic force and the second magnetic force on both sides of the guide rail 1 are balanced in the horizontal direction.
[0047] Furthermore, the number of the second electromagnetic coil 12 and the second permanent magnet 22 is even, forming multiple sets of braking components, while the guide rail 1 can still maintain force balance in the horizontal direction. Specifically, the multiple sets of braking components can be arranged in the same direction or in different directions. This disclosure does not limit this, as long as the guide rail 1 can maintain force balance in the horizontal direction, thereby preventing relative displacement between the slider 2 and the guide rail 1.
[0048] In some embodiments, refer to Figure 1 As shown, there is an even number of first permanent magnets 21. Multiple first permanent magnets 21 are symmetrically arranged in pairs on opposite sides of the slider 2, and the magnetic force of the corresponding two first permanent magnets 21 is the same. That is, the corresponding two first permanent magnets 21 can generate magnetic fields of the same magnitude, so that the slider 2 is subjected to the same magnetic force between the first permanent magnets 21 and the first electromagnetic coil 11 in the horizontal direction. In other words, the first magnetic force on both sides of the slider 2 is the same.
[0049] In specific implementation, a first electromagnetic coil 11 is provided at the position corresponding to the first permanent magnet 21 on the guide rail 1. That is, there are an even number of first permanent magnets 21 and first electromagnetic coils 11 to form multiple sets of driving components. When the first electromagnetic coil 11 and the second electromagnetic coil 12 are energized, a third magnetic force is generated between the first electromagnetic coil 11 and the first permanent magnet 21. The third magnetic force drives the first permanent magnet 21 to move towards or away from the first electromagnetic coil 11. The second magnetic force, the third magnetic force and the elastic force are in balance.
[0050] Continue to refer to Figure 1As shown, the direction of the third magnetic force is different from the direction of the elastic force. When the same current flows through the multiple first electromagnetic coils 11, the magnetic force generated by the multiple first electromagnetic coils 11 is the same. This further makes the third magnetic force on both sides of the guide rail 1 balanced in the horizontal direction. It can be understood that the magnetic force on the first permanent magnet 21 in the drive components on both sides of the guide rail 1 is the same, and the magnetic force generated by the first electromagnetic coils 11 is also the same. This makes the guide rail 1 subject to the same third magnetic force on both sides, so that the guide rail 1 can be balanced in the horizontal direction, thereby avoiding relative displacement between the slider 2 and the guide rail 1.
[0051] At this time, the same current flows through the second electromagnetic coils 12 on both sides of the guide rail 1, and the second magnetic forces on both sides of the guide rail 1 are consistent in the horizontal direction. That is to say, when the same current flows through the multiple first electromagnetic coils 11 and the same current flows through the second electromagnetic coils 12 on both sides of the guide rail 1, the second magnetic forces, elastic forces, and third magnetic forces on both sides of the guide rail 1 are balanced with each other, so that the guide rail 1 can be balanced in the horizontal direction. This ensures that the slider 2 can always be suspended with the guide rail 1 during the sliding process, avoiding friction and abnormal noise, and also ensuring structural stability.
[0052] Of course, it should be noted that different magnitudes of current can flow through the first electromagnetic coil 11 and the second electromagnetic coil 12 at different positions. This disclosure does not limit this, as long as the first electromagnetic coil 11 and the second electromagnetic coil 12, which are relatively symmetrical, have the same magnitude of current, the guide rail 1 can be balanced in the horizontal direction so as to avoid relative displacement between the slider 2 and the guide rail 1.
[0053] In other embodiments, reference is made to Figure 2 As shown, there are multiple first permanent magnets 21, which are arranged on the same side of the slider 2. The guide rail 1 is provided with a first electromagnetic coil 11 at the position corresponding to the first permanent magnet 21. When the first electromagnetic coil 11 and the second electromagnetic coil 12 are energized, a third magnetic force is generated between the first electromagnetic coil 11 and the first permanent magnet 21. The third magnetic force drives the first permanent magnet 21 to move towards or away from the first electromagnetic coil 11. The second magnetic force, the third magnetic force and the elastic force are in balance.
[0054] Continue to refer to Figure 1 As shown, the direction of the third magnetic force is the same as the direction of the elastic force. By changing the magnitude of the current in the second electromagnetic coil 12, the magnitude of the second magnetic force generated by the second electromagnetic coil 12 and the second permanent magnet 22 can be changed, thereby making the resultant force of the second magnetic force, the third magnetic force and the elastic force balanced. With this setting, the guide rail 1 can be balanced in the horizontal direction when the first electromagnetic coil 11 and the second electromagnetic coil 12 are energized.
[0055] Of course, it should be noted that multiple braking components can also be distributed in other directions. This disclosure does not limit this, as long as the size of the current supplied to the second electromagnetic coil 12 is changed to ensure that the guide rail 1 can be balanced in the horizontal direction.
[0056] It should be noted that multiple sets of drive components can be arranged in the same direction or in different directions. This disclosure does not limit this, as long as the guide rail 1 can be balanced in the horizontal direction when the first electromagnetic coil 11 and the second electromagnetic coil 12 are energized, that is, the force balance can be achieved to avoid relative displacement between the slider 2 and the guide rail 1, and to ensure that the slider 2 can always be suspended with the guide rail 1 during the lifting process, so as to achieve contactless sliding throughout the entire process and thus avoid abnormal noise problems.
[0057] In some embodiments, refer to Figure 3 and Figure 4 As shown, the first electromagnetic coil 11 includes a plurality of first sub-electromagnetic coils 111 arranged sequentially along the extension direction of the guide rail 1. When each first sub-electromagnetic coil 111 is energized, the two ends of the first sub-electromagnetic coil 111 respectively form a positive pole and a negative pole, and the positions of the positive pole and the negative pole alternate.
[0058] Continue to refer to Figure 3 and Figure 4 As shown, one of the two adjacent first sub-electromagnetic coils 111 is arranged opposite to the first permanent magnet 21 with the same polarity and generates a first driving magnetic force that repels each other, while the other of the two adjacent first sub-electromagnetic coils 111 is arranged opposite to the first permanent magnet 21 with the opposite polarity and generates a second driving magnetic force that attracts each other. The first driving magnetic force and the second driving magnetic force together form the first magnetic force.
[0059] In other words, among the two adjacent first sub-electromagnetic coils 111 located on both sides of the first permanent magnet 21, one repels the first permanent magnet 21 and the other attracts it. Under the action of the repulsive force (i.e., the first driving magnetic force) and the attractive force (i.e., the second driving magnetic force), the first permanent magnet 21 can be pushed from the first first sub-electromagnetic coil 111 to the second first sub-electromagnetic coil 111. When the first permanent magnet 21 moves into place, the magnetic field direction of the first sub-electromagnetic coil 111 at the current position changes. By repeating this setting, attractive and repulsive forces can continue to be generated between the current first sub-electromagnetic coil 111 and the next first sub-electromagnetic coil 111. The direction of the attractive force at the current position is the same as the direction of the previous attractive force, and the direction of the repulsive force is the same as the direction of the previous repulsive force. This generates a first magnetic force that pushes the slider 2 to slide along the extension direction of the guide rail 1, thereby pushing the first permanent magnet 21 to continue moving forward.
[0060] In practice, multiple first sub-electromagnetic coils 111 are arranged sequentially along the extension direction of the guide rail 1. This arrangement enables the first permanent magnet 21 to move along the arrangement direction of the multiple first sub-electromagnetic coils 111, thereby driving the slider 2 to slide along the extension direction of the guide rail 1, and ultimately driving the car window glass to rise and fall.
[0061] Specifically, an alternating current is passed through the first sub-electromagnetic coil 111, which causes the first sub-electromagnetic coil 111 to generate a magnetic field with alternating magnetic poles. Furthermore, by using different initial directions of the alternating current, the magnetic field directions generated by adjacent first sub-electromagnetic coils 111 can be different, thereby generating a continuous first driving magnetic force and a second driving magnetic force, which drive the slider 2 to slide along the extension direction of the guide rail 1.
[0062] In some embodiments, refer to Figure 1 As shown, guide rail 1 is a T-shaped guide rail, which includes a connected crossbeam 13 and a longitudinal beam 14. The crossbeam 13 and the longitudinal beam 14 are distributed in a T-shape, and the slider 2 is at least surrounding the periphery of the crossbeam 13; in other embodiments, refer to Figure 2 As shown, the guide rail 1 is a Z-shaped guide rail. The Z-shaped guide rail includes a guide rail body 15 and flanges 16 disposed on both sides of the end of the guide rail body 15. The flanges 16 on both sides and the guide rail body together form a Z shape. The slider 2 is at least surrounded by the outer periphery of the flanges 16 on both sides, which can prevent the guide rail 1 or the slider 2 from coming off in the horizontal direction and can ensure structural stability.
[0063] In other words, the slider 2 is positioned at the end of the guide rail 1 with a larger cross-section and surrounds the outside of the larger end of the guide rail 1. This prevents the slider 2 or the guide rail 1 from detaching while allowing the slider 2 to slide relative to the guide rail 1, ensuring structural stability. Of course, the guide rail 1 can also be of other shapes; this disclosure does not limit this, as long as the slider 2 can slide relative to the guide rail 1 and fits the installation space on the car door. Furthermore, the specific positions of the first permanent magnet 21, the first electromagnetic coil 11, the second permanent magnet 22, and the second electromagnetic coil 12 can be specifically set according to actual needs, as long as the slider 2 can suspend relative to the guide rail 1 and slide.
[0064] Other embodiments of this disclosure provide a vehicle door, including a door body, a window glass, and a window glass lifting mechanism as described in any of the above embodiments. The window glass lifting mechanism is disposed on the door body, and the slider is connected to the window glass.
