Description

Technical Field

[0001] The present application relates to the field of electric windows, and in particular to a connection assembly for an extremely narrow rocker arm motor. Background Art

[0002] The sash and window frame of an electric window are usually connected by a rocker motor, a rocker arm, a slide rail, and a slider. The rocker motor then drives the rocker arm to move, thereby driving the slider to slide in the slide rail, so that the window sash opens and closes relative to the window frame.

[0003] The shape of the existing slider is usually a rectangular block. In order to adapt to the shape of the slider, the width of the slide rail is relatively wide. Since the slider is a rectangular block, the slide rail and the slider are in surface contact, which causes the slider to get stuck due to the friction between the slide rail during use, which in turn causes the rocker motor to malfunction, making the electric window unable to work.

[0004] Secondly, the slide rail and the slider on the existing electric window are usually assembled in a zero-match manner. As the rocker arm motor moves, the angle of the rocker arm changes as the rocker arm rotates, and the slider and the slide rail are assembled in a zero-clearance manner. As a result, when the rocker arm rotates significantly, the direction of the force exerted by the rocker arm on the slider changes dramatically under the drive of the rocker arm, which makes it easier for the slider and the slide rail to get stuck.

[0005] When using the electric window for tilting or opening, the rocker arm needs to be tilted relative to the slider in a direction perpendicular to the slide rail (vertical direction) to meet the requirements of opening or tilting. However, the existing slider and the slide rail are matched with zero clearance, so that the rocker arm can only move on the same horizontal plane and cannot tilt relative to the sliding plane of the slider. As a result, the slider and the slide rail are easily stuck during the tilting and opening process, which leads to other driving methods often being used for the electric windows for tilting and opening.

[0021] The rocker arm moves along the axial direction of the fixing member to drive the sliding block to move, so that one of the first inclined surfaces moves toward the corresponding second inclined surface to change the inclination angle of the rocker arm relative to the sliding rail.

[0048] An embodiment of the present application provides a connection assembly for an extremely narrow rocker arm motor, comprising:

[0049] The slide rail has a slide groove along the length direction;

[0050] A slider, one end of which is slidably disposed in the slide groove, and the other end of which extends from the notch of the slide groove to the outside, and the slide rail and the slider are clearance-matched;

[0051] A rocker arm has one end disposed on the rocker arm motor and the other end rotatably connected to an end of the slider away from the slide rail, and a clearance fit is provided at the connection between the rocker arm and the slider.

[0052] In this embodiment, after the rocker arm motor is energized, it drives the rocker arm to swing, and the swing of the rocker arm drives the slider to slide in the slide rail. Since one end of the slider is in the slide groove, the other end extends from the notch of the slide groove to the outside, and the slide rail and the slider, and the connection between the rocker arm and the slider are all fitted through clearance, the slider can slide smoothly, and the sliding of the slider drives the window sash to open and close relative to the window frame.

[0053] The slider and the slide rail are fitted with clearance, so that the slider can tilt during movement, thereby presenting line contact, reducing the contact area between the slider and the slide rail, reducing friction, and avoiding the problem of the slider getting stuck.

[0054] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0055] An embodiment of the present application provides a connection assembly 100 of an extremely narrow rocker arm motor, comprising:

[0056] The slide rail 110 is provided with a slide groove 110a along the length direction;

[0057] A slider 120, one end of which is slidably disposed in the slide groove 110a, and the other end of which extends from the notch of the slide groove 110a to the outside, and the slide rail 110 and the slider 120 are clearance-matched;

[0058] One end of the rocker arm 130 is disposed on the rocker arm 130 motor, and the other end is rotatably connected to the end of the slider 120 away from the slide rail 110 , and the connection between the rocker arm 130 and the slider 120 is clearance-matched.

[0059] Please refer to Figures 1 to 5 In this embodiment, after the rocker arm 130 motor is energized, the rocker arm 130 is driven to swing, and the swing of the rocker arm 130 drives the slider 120 to slide in the slide rail 110. Since one end of the slider 120 is in the slide groove 110a, and the other end extends to the outside from the notch of the slide groove 110a, and the connection between the slide rail 110 and the slider 120 and between the rocker arm 130 and the slider 120 are all clearance-matched, the slider 120 can slide smoothly, and the sliding of the slider 120 drives the window sash to open and close relative to the window frame.

[0060] Clearance fit is adopted between the slider 120 and the slide rail 110, and between the rocker arm 130 and the slider 120, so that the slider 120 can tilt during movement, thereby presenting line contact, reducing the contact area between the slider 120 and the slide groove 110a, reducing friction, and avoiding the problem of the slider 120 getting stuck.

[0061] It should be noted that the slide rail 110 is a long strip component with a slide groove 110a along the length direction. The slide rail 110 provides a guide channel, and the slide block 120 can slide smoothly along the predetermined track through the slide groove 110a, ensuring the movement direction and trajectory of the slide block 120, thereby improving the stability and reliability of the connection component.

[0062] One end of the slider 120 is arranged in the slide groove 110a, and the other end passes through the slide groove 110a and extends to the outside, and is clearance-matched with the slide rail 110. The slider 120 slides in the slide groove 110a to realize the transmission function of the rocker arm 130 motor. The clearance fit allows the slider 120 to slide smoothly in the slide rail 110, reducing friction and jamming. Through the clearance fit, the slider 120 can tilt to a certain extent during the movement, so that the slider 120 and the slide groove 110a are in line contact, reducing the contact area, reducing friction, and preventing jamming.

[0063] The corners of the slider 120 are all rounded, so that the slider 120 can slide more smoothly in the slide groove 110a.

[0064] One end of the rocker arm 130 is connected to the rocker arm 130 motor, and the other end is connected to the end of the slider 120 away from the slide rail 110. The rocker arm 130 is driven by the rocker arm 130 motor to swing, thereby driving the slider 120 to slide in the slide rail 110, and finally realizing the opening and closing action of the window sash. The connection between the rocker arm 130 and the slider 120 enables the slider 120 to slide smoothly in the slide rail 110. The rocker arm 130 is roughly in the shape of a long strip.

[0065] In at least one embodiment of the present application, a fixing member 140 is provided at the connection between the rocker arm 130 and the slider 120, and the two ends of the fixing member 140 are respectively provided on the rocker arm 130 and the slider 120, and the fixing member 140 is respectively loosely matched with the rocker arm 130 and the slider 120.

[0066] Please refer to Figures 1 to 6 In this embodiment, one end of the fixing member 140 is mounted on the rocker arm 130, and the other end is mounted on the slider 120. Since the fixing member 140 is clearance-fitted with the rocker arm 130 and the slider 120, the slider 120 can adapt to the change in the movement angle of the rocker arm 130 when sliding in the slide rail 110, thus avoiding the problem of the slider 120 being easily stuck in the traditional tight-fitting manner.

[0067] During the entire movement process, the fixing member 140 allows a certain adjustment space between the slider 120 and the rocker arm 130 through clearance fit, so that the slider 120 can slide smoothly in the slide rail 110, thereby achieving smooth opening and closing of the window sash.

[0068] Since the fixing member 140 is clearance-fitted with the rocker arm 130 and the slider 120 , the slider 120 can automatically adjust its angle when sliding in the slide rail 110 , thereby avoiding friction and jamming caused by a tight fit.

[0069] The clearance fit provides a certain degree of freedom, so that the slider 120 can slide smoothly during the movement, and the overall movement is smoother, thereby improving the operating stability of the electric window.

[0070] It should be noted that the fixing part 140 is a rivet, and the fixing part 140 connects the rocker arm 130 and the slider 120 by means of clearance fit, so that they can maintain a certain flexibility during movement and reduce the possibility of friction and jamming. The clearance fit allows the fixing part 140 to allow a certain degree of freedom during movement, avoiding the jamming problem caused by the traditional tight fit method, and improving the operating stability and life of the overall assembly.

[0071] In at least one embodiment of the present application, the length of the fixing member 140 is denoted as a, a mounting groove 120a is formed on a side of the slider 120 away from the rocker arm 130, the fixing member 140 passes through the slider 120 and extends into the mounting groove 120a, and a distance from a side of the rocker arm 130 away from the slider 120 to an inner wall of the mounting groove 120a is denoted as b, satisfying the relationship: a>b.

[0072] Please refer to Figures 1 to 6 In this embodiment, one end of the fixing member 140 is mounted on the rocker arm 130 , and the other end passes through the slider 120 and extends into the mounting groove 120 a on the side of the slider 120 away from the rocker arm 130 .

[0073] Ensure that the length a of the fixing member 140 is greater than the distance b from the side of the rocker arm 130 away from the slider 120 to the inner wall of the mounting groove 120a, that is, the relationship a>b is satisfied, so that the fixing member 140 has enough free space in the mounting groove 120a.

[0074] When the motor of the rocker arm 130 drives the rocker arm 130 to move, the fixing member 140 enables the slider 120 to slide smoothly in the slide rail 110 through clearance fit.

[0075] During the movement, since the length of the fixing member 140 is greater than the distance b, a certain adjustment angle space can be maintained between the rocker arm 130 and the slider 120 to reduce friction and jamming.

[0076] The fixing member 140 passes through the slider 120 and extends into the mounting groove 120 a , thereby increasing the connection stability between the slider 120 and the rocker arm 130 and preventing the slider 120 from falling off during movement.

[0077] Secondly, since the length a of the fixing member 140 is greater than the distance b from the side of the rocker arm 130 away from the slider 120 to the inner wall of the mounting groove 120a, it is ensured that the fixing member 140 has sufficient space for movement relative to the slider 120 and the rocker arm 130, so that the slider 120 can automatically adjust its angle when sliding in the slide rail 110, reducing friction and jamming.

[0078] It should be noted that the mounting groove 120a is formed by an inward depression on the side of the slider 120 away from the rocker arm 130; and the length of the fixing member 140 is smaller than the longest distance from the rocker arm 130 to the slider 120 (in the length direction of the fixing member 140).

[0079] In at least one embodiment of the present application, a first positioning hole 130a is provided at one end of the rocker arm 130 close to the slider 120, and a second positioning hole 120b is provided on the slider 120, and the second positioning hole 120b is connected to the mounting groove 120a, and one end of the fixing member 140 is provided on the rocker arm 130, and the other end passes through the first positioning hole 130a, the second positioning hole 120b and extends into the mounting groove 120a.

[0080] Please refer to Figures 1 to 6 In this embodiment, first, one end of the fixing member 140 is inserted into the first positioning hole 130 a on the rocker arm 130 to fix it on the rocker arm 130 .

[0081] Next, the other end of the fixing member 140 is inserted into the second positioning hole 120 b on the slider 120 , passes through the slider 120 and extends into the mounting groove 120 a .

[0082] The fixing member 140 is fixed to the rocker arm 130 through the first positioning hole 130 a to ensure a stable connection to the rocker arm 130 .

[0083] The fixing member 140 is fixed to the slider 120 through the second positioning hole 120 b and extends into the mounting groove 120 a , thereby increasing the fixing effect between the slider 120 and the rocker arm 130 , so that the rocker arm 130 is connected to the slider 120 through the fixing member 140 .

[0084] When the motor of the rocker arm 130 drives the rocker arm 130 to move, the fixing member 140 connects the rocker arm 130 and the slider 120 together through the first positioning hole 130 a and the second positioning hole 120 b , so that the slider 120 can slide smoothly in the slide rail 110 .

[0085] The fixing member 140 can firmly connect the rocker arm 130 and the slider 120, thereby increasing the stability of the connection and reducing the risk of loosening and falling off.

[0086] The fixing member 140 passes through the slider 120 and extends into the mounting groove 120 a , so that the movement of the slider 120 in the slide rail 110 is more stable, and the friction and wear between the slider 120 and the slide groove 110 a are reduced.

[0087] It should be noted that the first positioning hole 130a is a through hole, and its shape is generally a circular hole;

[0088] The provision of the first positioning hole 130 a enables the fixing member 140 to be connected to the rocker arm 130 , thereby improving the stability of the fixing member 140 .

[0089] A second positioning hole 120b is provided on the slider 120, and the second positioning hole 120b is connected to the mounting groove 120a. The second positioning hole 120b is located on the side of the slider 120 close to the rocker arm 130. The second positioning hole 120b is a through hole, and its shape is roughly a circular hole, so that the fixing member 140 can pass through the slider 120 and extend into the mounting groove 120a.

[0090] The fixing member 140 is respectively fitted with the first positioning hole 130a and the second positioning hole 120b with a clearance to increase the degree of freedom among the fixing member 140, the rocker arm 130 and the slider 120, so as to avoid the slider 120 from getting stuck due to excessive friction between the slider 120 and the inner wall of the slide groove 110a caused by the direction of the force exerted by the rocker arm 130 on the slider 120 during the movement of the slider 120.

[0091] In at least one embodiment of the present application, one end of the fixing member 140 is rotatably connected to the rocker arm 130 , and the other end thereof passes through the rocker arm 130 and is rotatably connected to the slider 120 .

[0092] Please refer to Figures 1 to 6 In this embodiment, one end of the fixing member 140 is mounted on the rocker arm 130 by a rotational connection, so that the fixing member 140 can rotate freely on the rocker arm 130.

[0093] The other end of the fixing member 140 passes through the rocker arm 130 and is mounted on the slider 120 by a rotational connection, so that the fixing member 140 can rotate freely on the slider 120 .

[0094] When the motor of the rocker arm 130 drives the rocker arm 130 to move, the fixing member 140 serves as a connection between the rocker arm 130 and the slider 120 and allows relative movement between the two.

[0095] Since both ends of the fixing member 140 are rotatably connected, the rocker arm 130 and the slider 120 can flexibly adjust their positions and angles during the movement, thereby reducing resistance and stress concentration during the movement.

[0096] During the sliding process of the slider 120 in the slide rail 110 , the fixing member 140 maintains its connection function and allows the slider 120 to slide smoothly in the slide rail 110 .

[0097] Through the rotational connection, the fixing member 140 can flexibly adapt to the movement of the rocker arm 130 and the slider 120, reducing stress concentration at the connection and extending the service life of the components.

[0098] The fixing member 140 is rotatably connected and has clearance fit with the rocker arm 130 and the slider 120 , so that the rocker arm 130 and the slider 120 can freely adjust their positions and angles during the movement, ensuring the stability and smoothness of the movement.

[0099] The rotation connection of the fixing member 140 allows the rocker arm 130 and the slider 120 to move freely within a certain angle range, thereby improving the adaptability and flexibility of the connection assembly and being able to meet the use requirements of different electric windows.

[0100] By rotatably connecting the two ends of the fixing member 140 to the rocker arm 130 and the slider 120 respectively, the fixing member 140 can flexibly adapt to different positions and angles of the rocker arm 130 and the slider 120 during movement, thereby reducing stress concentration, improving the durability and reliability of the connection, ensuring the stability and smoothness of the movement, and enhancing the adaptability and flexibility of the connection assembly.

[0101] One end of the fixing member 140 is connected to the rocker arm 130 by a rotational connection, so that the fixing member 140 can achieve a certain degree of free rotation on the rocker arm 130 to adapt to different angles and positions of the rocker arm 130. Through the rotational connection, the fixing member 140 can flexibly adjust its position according to the movement of the rocker arm 130, reducing the stress concentration between the fixing member 140 and the rocker arm 130 and improving the durability and reliability of the connection.

[0102] The other end of the fixing member 140 passes through the rocker arm 130 and extends to the slider 120, and is connected to the slider 120 by a rotational connection. The fixing member 140 can not only fix the rocker arm 130 and the slider 120, but also realize a certain degree of free rotation on the slider 120 to adapt to different positions and angles of the slider 120. Through the rotational connection, the fixing member 140 can flexibly adjust its position according to the movement of the slider 120, reduce the stress concentration between the fixing member 140 and the slider 120, and improve the durability and reliability of the connection.

[0103] In at least one embodiment of the present application, the connection assembly 100 of the ultra-narrow rocker arm motor further includes:

[0104] An elastic member 150, wherein the elastic member 150 is disposed between the rocker arm 130 and the slider 120, and the fixing member 140 passes through the elastic member 150 and extends into the slider 120;

[0105] The rocker arm 130 is tilted along the axis of the fixing member 140 to press the elastic member 150 to change the inclination angle between the rocker arm 130 and the slide rail 110 .

[0106] Please refer to Figures 1 to 6 In this embodiment, the elastic member 150 is disposed between the rocker arm 130 and the slider 120 , and the fixing member 140 penetrates the elastic member 150 and the slider 120 .

[0107] One end of the fixing member 140 is fixed on the rocker arm 130 , and the other end extends into the slider 120 .

[0108] When the motor of the rocker arm 130 drives the rocker arm 130 to move, the rocker arm 130 tilts along the axis direction of the fixing member 140 and presses the elastic member 150 .

[0109] The elastic member 150 generates elastic deformation when being squeezed, and provides a reaction force, so that the rocker arm 130 is reset after the movement is completed, and the slider 120 is kept sliding smoothly in the slide rail 110 .

[0110] The tilting of the rocker arm 130 changes the inclination angle between the rocker arm 130 and the slide rail 110 , reduces the contact area between the slider 120 and the slide rail 110 , reduces the friction force, and increases the margin space.

[0111] When the rocker arm 130 completes the movement, the elastic force of the elastic member 150 restores it to its original state, pushing the rocker arm 130 to reset, thereby ensuring the smooth progress of the next movement cycle.

[0112] Through the action of the elastic member 150 , the connection between the rocker arm 130 and the slider 120 is more stable, and the slider 120 slides more smoothly in the slide rail 110 .

[0113] In the application of the tilt window, the inclination of the swing arm 130 allows the window to be adjusted at different angles, providing a more flexible ventilation method.

[0114] After the rocker arm 130 is tilted, a clearance fit is adopted between the slider 120 and the slide rail 110. The deformation of the elastic member 150 reduces the contact area between the slider 120 and the slide rail 110, reduces the friction between the slider 120 and the slide rail 110, avoids the slider 120 from getting stuck in the slide rail 110, and improves the smoothness of opening and closing the window.

[0115] In the application of suspended windows, the tilting of the swing arm 130 allows the window to be opened at different tilting angles, providing more window opening options.

[0116] After the rocker arm 130 is tilted, a clearance fit is adopted between the slider 120 and the slide rail 110. The deformation of the elastic member 150 reduces the contact area between the slider 120 and the slide rail 110, reduces the friction between the slider 120 and the slide rail 110, avoids the slider 120 from getting stuck in the slide rail 110, and improves the smoothness of opening and closing the window.

[0117] The margin space of the slider 120 in the slide rail 110 is increased to ensure that the slider 120 can slide smoothly at different angles. The movement flexibility of the slider 120 is improved, the special requirements of the tilt and hang windows are met, and the jamming problem between the slider 120 and the slide rail 110 is avoided.

[0118] By arranging an elastic member 150 between the rocker arm 130 and the slider 120, the rocker arm 130 can be tilted along the axial direction of the fixing member 140 during movement. The clearance fit and the elastic deformation of the elastic member 150 enable the rocker arm 130 to tilt during movement, thereby increasing the margin space of the slider 120 in the slide rail 110 to avoid jamming, improving the smoothness of movement and the durability of the components, and enhancing the stability and adaptability of the connection to avoid the problem of the rocker arm 130 motor driving the slider 120 to get stuck in the slide groove 110a in the suspended and tilted electric windows.

[0119] The elastic member 150 is a flexible gasket used to generate deformation to increase the angle between the rocker arm 130 and the slide rail 110, so that the connection assembly 100 of the extremely narrow rocker arm motor can be applied to the electric window that tilts inward or opens.

[0120] In at least one embodiment of the present application, the slider 120 includes a sliding portion 121 and an inclined portion 122 provided on the sliding portion 121, the sliding portion 121 is received in the slide groove 110a, the inclined portion 122 penetrates the slide groove 110a and extends to the outside, and the sliding portion 121 is clearance-matched with the slide groove 110a;

[0121] The slide rail 110 is provided with a first inclined surface 110 b , and the first inclined surface 110 b is loosely matched with the inclined portion 122 .

[0122] Please refer to Figures 1 to 6 In this embodiment, the sliding portion 121 of the slider 120 is received in the slide groove 110 a , and the inclined portion 122 passes through the slide groove 110 a and extends to the outside.

[0123] The slide rail 110 is provided with a first inclined surface 110 b which is clearance-matched with the inclined portion 122 of the slider 120 .

[0124] When the swing arm 130 motor drives the slider 120 to slide in the slide rail 110 , the sliding portion 121 moves smoothly in the slide groove 110 a , and the inclined portion 122 is loosely matched with the first inclined surface 110 b of the slide rail 110 .

[0125] During the sliding process, the inclined portion 122 of the slider 120 can be inclined along with the first inclined surface 110 b of the slide rail 110 to adjust the inclination angle of the slider 120 .

[0126] Due to the clearance fit, the friction between the sliding portion 121 and the sliding groove 110 a is relatively small, and the slider 120 can slide smoothly to avoid being stuck.

[0127] In applications of tilting or cantilevering, the inclined portion 122 of the slider 120 can slide smoothly at different tilt angles through the guidance of the first inclined surface 110 b.

[0128] When the tilt angle of the window sash needs to be adjusted, the rocker arm 130 motor drives the slider 120 , and the tilt portion 122 of the slider 120 is tilted and adjusted by the first inclined surface 110 b , thereby increasing the freedom of movement of the slider 120 .

[0129] The clearance between the inclined portion 122 and the first inclined surface 110 b enables the slider 120 to automatically adjust its inclination angle during the sliding process, thereby improving the movement flexibility of the slider 120 .

[0130] The clearance between the sliding portion 121 and the slide groove 110 a is matched, so that the friction force of the slider 120 is small during the sliding process, thereby preventing the slider 120 from getting stuck in the slide rail 110 .

[0131] The inclined portion 122 enables the slider 120 to adapt to the different movement requirements of the inward tilt or suspended opening window, increasing the applicability and flexibility of the electric window. Since a gap is formed between the inclined portion 122 and the first inclined surface 110b, when the rocker arm 130 is tilted relative to the slide rail 110 along the length direction of the fixing member 140, interference between the slide rail 110 and the slider 120 is avoided, thereby preventing the slider 120 and the slide rail 110 from getting stuck.

[0132] By reducing friction and jamming, the slider 120 and the slide rail 110 cooperate more smoothly, thereby improving the stability and durability of the overall assembly.

[0133] The shape of the inclined portion 122 is roughly an inverted frustum, and the clearance between the sliding portion 121 and the sliding groove 110a is matched, so that the slider 120 can slide smoothly, reducing friction and jamming.

[0134] When the slider 120 is tilted, a line contact is formed between the slider 120 and the slide groove 110a, thereby avoiding excessive friction and being unable to be applied to inward-tilted or suspended windows.

[0135] The slide rail 110 is provided with a first inclined surface 110 b , and the first inclined surface 110 b is loosely matched with the inclined portion 122 .

[0136] The clearance fit between the first inclined surface 110 b and the inclined portion 122 enables the slider 120 to tilt when sliding in the slide rail 110 , thereby changing the contact angle between the slider 120 and the slide rail 110 .

[0137] The first inclined surface 110b enables the slider 120 to automatically adjust its tilt angle as the angle of the rocker arm 130 changes during the sliding process, thereby reducing friction, avoiding jamming, and adapting to different window opening methods.

[0138] The clearance between the inclined portion 122 and the first inclined surface 110 b enables the slider 120 to automatically adjust its inclination angle during the sliding process, thereby improving the movement flexibility of the slider 120 .

[0139] The inclined portion 122 enables the slider 120 to adapt to different movement requirements of the inward tilt or suspended opening window, thereby increasing the applicability and flexibility of the electric window.

[0140] The sliding portion 121 is generally in the shape of a block.

[0141] In at least one embodiment of the present application, there are two first inclined surfaces 110b, the slide groove 110a is formed between the two first inclined surfaces 110b, the two sides of the inclined portion 122 have second inclined surfaces 122a, the two first inclined surfaces 110b are respectively arranged opposite to the two second inclined surfaces 122a, and an avoidance space 120c is formed between each pair of the first inclined surfaces 110b and the second inclined surfaces 122a;

[0142] The rocker arm 130 moves along the axial direction of the fixing member 140 to drive the slider 120 to move, so that one of the first inclined surfaces 110b moves toward the corresponding second inclined surface 122a to change the inclination angle of the rocker arm 130 relative to the slide rail 110.

[0143] Please refer to Figures 1 to 6 In this embodiment, the sliding portion 121 of the slider 120 is received in the slide groove 110 a , and the second inclined surfaces 122 a on both sides of the inclined portion 122 are arranged opposite to the two first inclined surfaces 110 b on the slide rail 110 .

[0144] There is an escape space 120c between the first inclined surface 110b and the second inclined surface 122a to avoid mutual interference during the sliding process.

[0145] When the motor of the rocker arm 130 drives the rocker arm 130 to move, if the rocker arm 130 is tilted along the axis direction of the fixing member 140 (tilted up and down relative to the axis of the fixing member 140), it can still drive the slider 120 to slide in the slide groove 110a.

[0146] During the sliding process of the slider 120 , the second inclined surface 122 a of the inclined portion 122 is loosely matched with the first inclined surface 110 b , so that the slider 120 can be tilted as required, and the slider 120 does not interfere with the slide rail 110 .

[0147] By the up and down tilting movement of the rocker arm 130 relative to the axis of the fixing member 140 , one of the first inclined surfaces 110 b of the slider 120 is brought close to the corresponding second inclined surface 122 a , thereby changing the inclination angle of the rocker arm 130 relative to the slide rail 110 .

[0148] The avoidance space 120 c ensures the smoothness of the sliding block 120 when it slides obliquely, reduces the friction force, and improves the movement stability of the sliding block 120 .

[0149] The avoidance space 120c ensures smooth cooperation between the first inclined surface 110b and the second inclined surface 122a, reduces the friction and jamming of the slider 120 in the slide groove 110a, and improves the stability of movement.

[0150] By avoiding mutual interference between the first bevel 110b and the second bevel 122a during the sliding process, possible mechanical failures and jamming are reduced, the safety of the electric window is improved, and the connection assembly 100 of the ultra-narrow rocker arm motor can be suitable for the use of inward-tilted windows or suspended windows.

[0151] The rocker arm 130 moves along the axial direction of the fixing member 140, driving the slider 120 to slide and tilt in the slide groove 110a, so that the slider 120 can slide smoothly at different inclination angles, reduce friction and jamming, improve the smoothness of movement and the durability of the components, enhance the stability and adaptability of the connection, and is suitable for different types of electric windows.

[0152] In at least one embodiment of the present application, a fitting surface 122b is provided on one side of the inclined portion 122 close to the rocker arm 130, and two second inclined surfaces 122a are respectively located on both sides of the fitting surface 122b, and an angle between the second inclined surface 122a and the fitting surface 122b is denoted as α, satisfying the relationship: 25°≤α≤65°.

[0153] Please refer to Figures 1 to 6 In this embodiment, a fitting surface 122 b is provided on a side of the inclined portion 122 of the slider 120 close to the rocker arm 130 , so that the inclined portion 122 is in contact with and connected to the rocker arm 130 .

[0154] The second inclined surfaces 122a are respectively located on both sides of the bonding surface 122b, and an angle α between the second inclined surface 122a and the bonding surface 122b satisfies 25°≤α≤65°.

[0155] When the swing arm 130 motor drives the slider 120 to slide in the slide rail 110 , the contact surface 122 b of the slider 120 keeps in contact with the swing arm 130 , providing stable support.

[0156] When the swing arm 130 motor drives the slider 120 to slide in the slide rail 110 , the contact surface 122 b of the slider 120 keeps in contact with the swing arm 130 , providing stable support.

[0157] When the slider 120 slides in the slide groove 110a, the second inclined surface 122a cooperates with the first inclined surface 110b to make the slider 120 tilt as required.

[0158] Through the movement of the rocker arm 130 , the inclined portion 122 of the slider 120 is tilted in the slide groove 110 a , and the tilt angle of the slider 120 is adjusted.

[0159] The angle α is set between 25° and 65° to ensure that the slider 120 has a proper tilt angle and stability during the tilt sliding process.

[0160] The fitting surface 122 b increases the contact area between the slider 120 and the rocker arm 130 , enhances the stability of the slider 120 , and reduces the shaking and instability of the slider 120 during movement.

[0161] By setting the angle α between 25° and 65°, the slider 120 can adapt to different movement requirements of the inward tilt or suspended window, thereby increasing the applicability and flexibility of the electric window.

[0162] A reasonable angle range is set to ensure that the slider 120 has an appropriate tilt angle during the tilt sliding process, thereby reducing friction and jamming and improving the smoothness of the movement.

[0163] The angle between the second inclined surface 122a and the fitting surface 122b is denoted as α, which satisfies the relationship: 25°≤α≤65°, thereby ensuring that the slider 120 has a proper inclination angle and stability during the inclined sliding process.

[0164] By setting the angle α between 25° and 65°, it is ensured that the slider 120 has a sufficient inclination angle during the sliding process, thereby reducing friction and jamming, while maintaining the stability of the slider 120 .

[0165] When the angle α is less than 25°, the tilting ability of the slider 120 is insufficient, resulting in a larger contact area between the slider 120 and the slide groove 110 a.

[0166] Due to the large contact area, the friction force increases when the slider 120 slides in the slide groove 110 a, which may cause uneven sliding or even jamming.

[0167] An insufficient tilt angle will also limit the movement flexibility of the slider 120, making it unable to adapt to various window opening angles of inward tilting or hanging windows, thereby reducing the applicability of the electric window.

[0168] When the angle α is greater than 65°, the slider 120 is excessively tilted, which may cause the stability of the slider 120 in the slide groove 110 a to decrease.

[0169] Too large an inclination angle may cause the slider 120 to shake or become unstable during the sliding process, thus affecting the normal use of the electric window.

[0170] An excessively large tilt angle may also cause mechanical interference between the slider 120 and the slide groove 110 a , increase wear, or even damage the slider 120 or the slide groove 110 a .

[0171] In at least one embodiment of the present application, the connection assembly 100 of the ultra-narrow rocker arm motor further includes:

[0172] There are at least two wear-resistant gaskets 160, and the two wear-resistant gaskets 160 are respectively located on both sides of the elastic member 150. The fixing member 140 sequentially passes through the rocker arm 130, one of the wear-resistant gaskets 160, the elastic member 150, the other wear-resistant gasket 160 and the slider 120, and extends into the slider 120.

[0173] Please refer to Figures 1 to 6 In this embodiment, two wear-resistant gaskets 160 are respectively installed on both sides of the elastic member 150.

[0174] The fixing member 140 sequentially passes through the rocker arm 130 , one of the wear-resistant gaskets 160 , the elastic member 150 , the other wear-resistant gasket 160 , and the slider 120 , and extends into the slider 120 to ensure the fixation and connection of each component.

[0175] When the motor of the rocker arm 130 drives the rocker arm 130 to move, the fixing member 140 drives the slider 120 to slide in the slide rail 110 .

[0176] The wear-resistant pad 160 provides wear resistance between the fixing member 140 and other components to prevent the elastic member 150 from being excessively worn.

[0177] The elastic member 150 is deformed during the movement, providing a buffer and a restoring force, thereby ensuring the smooth movement of the slider 120 in the slide rail 110 .

[0178] The wear-resistant gasket 160 reduces the friction between the fixing member 140 and the rocker arm 130 , the elastic member 150 , and the slider 120 , thereby preventing wear and tear and improving the durability of the components.

[0179] Through the buffering and restoring effects of the elastic member 150 , the movement of the slider 120 in the slide rail 110 is made more stable, thereby avoiding the jamming phenomenon and improving the operating efficiency of the electric window.

[0180] The wear-resistant gasket 160 is made of wear-resistant material, such as wear-resistant rubber, plastic and other materials.

[0181] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
