[0001] The invention belongs to the technical field of vehicle window lifting, and in particular relates to a glass tray and a glass lifter. Background Art

[0002] The glass lifter is a lifting device for the car door and window glass, which is mainly divided into two categories: electric glass lifter and manual glass lifter.

[0003] Nowadays, many cars have abandoned the manual lifting method of crank handles for lifting and lowering (closing and opening) of door and window glass, and generally use button-type electric lifting method, that is, electric glass lifters. Electric glass lifters for cars are mostly composed of a drive motor, a reducer, a pull rope, a guide rail, a base for the glass mounting tray, etc., so that the base moves up and down along the guide rail.

[0004] In the prior art, the window glass is usually fixedly connected to the base through mounting holes, etc. However, in order to ensure the stability of the window glass during the lifting process, at least two mounting holes are required to install the two sides of the window glass respectively, and this mounting method makes the width and size of the window glass relatively limited; in addition, the traditional base does not take measures to solve the vibration generated by the window glass during use, so when the window glass is subjected to large vibration energy, it may cause it to break and even affect the personal safety of the user or installer. Therefore, solving the above problems is an important technical problem that the technicians in this field need to solve. Summary of the invention

[0036] The purpose, advantages and features of the present invention will be illustrated and explained by the non-limiting description of the following preferred embodiments. These embodiments are only typical examples of the application of the technical solution of the present invention, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.

[0037] In the description of the scheme, it should be noted that the terms "center", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0038] The present invention discloses a glass tray, including a vehicle-use vibration-reducing and energy-absorbing integrated component. Figures 1 to 4 As shown, the vehicle vibration reduction and energy absorption integrated part includes an integrated T-shaped elastic body 1, the body 1 includes an upper, middle and lower three-section structure, as well as a vibration reduction part and an energy absorption part; the vibration reduction part plays a buffering role, that is, the impact can be reduced by the vibration reduction part; the energy absorption part is used to absorb the vibration energy generated by the window glass during the lifting process, so that the lifting process of the window glass is more stable. Of course, the vehicle vibration reduction and energy absorption integrated part disclosed by the present invention can also be used for household glass installation or other equipment that needs to have a vibration reduction and energy absorption effect.

[0039] Combination Figure 1 and Figure 3 As shown, the vibration reduction part includes a first vibration reduction body 11 disposed in the middle section of the body 1, and the first vibration reduction body 11 includes a first buffer head 111 having a normal width and vertically upward; the shape of the first buffer head 111 includes a protrusion 112 smoothly upward in the middle and extension arms 113 located on both sides of the protrusion 112. The protrusion 112 contacts the bottom end of the vehicle window glass and plays a buffering role on the vehicle window glass.

[0040] Combination Figure 3 and Figure 4 As shown, in order to prevent the first buffer head 111 from being deformed excessively due to uneven force, thereby affecting the stability and safety of the lifting of the vehicle window glass, the first vibration damper 11 also includes a limit portion 114 extending normally from the body 1, the normal extension distance of the limit portion 114 is equal to the normal extension distance of the first buffer head 111, and the two extend in the same direction, and there is a gap 115 between the limit portion 114 and the extension arm 113. It can be seen that the limit portion 114 and the gap 115 are used to limit the deformation space of the first vibration damper 11 and enhance the integrity of the body 1.

[0041] Combination Figure 1 and Figure 3 As shown, an integrated pivot body 116 is disposed below the first buffer head 111, and the pivot body 116 is a semi-cylinder extending normally from the end face 117 of the first buffer head 111. A connecting arm 118 extends from both sides of the pivot body 116, and a secondary energy absorbing block 22 is vertically disposed upward at the distal end of the connecting arm 118, that is, the secondary energy absorbing block 22 is symmetrically disposed on both sides of the pivot body 116.

[0042] like Figure 2 As shown, a support block 119 is provided below the connecting arm 118, and one side of the support block 119 is integrally connected to the body 1. As is generally known, a triangle has stability, so in the present invention, the support block 119 is preferably arranged in a triangular shape, which enhances the integrity of the body 1 while ensuring the stability of the first vibration damping body 11.

[0043] Combination Figures 1 to 4 As shown, the vibration damping part further includes a second vibration damping body 12 disposed at the lower section of the body 1, the second vibration damping body 12 includes a second buffer head 120 having a normal width and extending vertically downward, and the second buffer head 120 is preferably made of TPU (polyurethane rubber). The normal extension direction of the second vibration damping body 12 from the body 1 is opposite to the normal extension direction of the first vibration damping body 11 from the body 1, that is, the first vibration damping body 11 and the second vibration damping body 12 are respectively located on the front and back sides of the body 1, and the axes of the two are parallel to each other.

[0044] like Figure 3 As shown, since the bottom of the traditional buffer head is designed as an arc shape protruding outward, it will form fatigue and then deform during long-term use, shortening the service life of the buffer block. In order to solve the above-mentioned problem, in the present invention, the second buffer head 120 is designed as a wavy structure composed of multiple line segments. Specifically, the second buffer head 120 includes a symmetrically arranged first arc surface 121 and a second arc surface 122 located between the two first arc surfaces 121, and the curvature of the first arc surface 121 is greater than the curvature of the second arc surface 122, and the two adjacent arc surfaces are smoothly transitioned. The second buffer head 120 also includes a clamping portion 123 arranged above the first arc surface 121.

[0045] like Figure 1 to Figure 2 As shown, the energy absorbing part includes a primary energy absorbing block 21 arranged on the upper section of the body 1, and the primary energy absorbing block 21 is symmetrically arranged on both sides of the "T"-shaped horizontal vertical portion 101 of the body 1, that is, the primary energy absorbing block 21 is symmetrically arranged on both sides of the above-mentioned body 1. The primary energy absorbing block 21 includes a first wedge-shaped body 211 with a protrusion, and the highest point of the protrusion of the first wedge-shaped body 211 is a smooth transition. The use of a smooth transition can effectively reduce the friction between the first wedge-shaped body 211 and the window glass to prevent the window glass from being scratched and damaged by the edges. The protrusion extension direction of the first wedge-shaped body 211 is the same as the normal extension direction of the first vibration damping body 11 from the body 1, that is, the first wedge-shaped body 211 is inclined from top to bottom in the direction of the first vibration damping body 11.

[0046] The energy absorbing part further includes a secondary energy absorbing block 22 disposed in the middle section of the body 1, the secondary energy absorbing block 22 being symmetrically disposed on both sides of the first vibration damping body 11, the secondary energy absorbing block 22 having a protruding second wedge-shaped body 221, the protrusion of the second wedge-shaped body 221 being a planar protrusion. The protrusion extension direction of the second wedge-shaped body 221 is the same as the normal extension direction of the second vibration damping body 12 from the body 1, that is, the second wedge-shaped body 221 is inclined from top to bottom toward the direction of the first wedge-shaped body 211.

[0047] like Figures 5 to 8 As shown, the glass tray includes any of the above-mentioned integrated vibration-absorbing and energy-absorbing parts for vehicles, the body 1 of which is embedded in a base 3 with a U-shaped longitudinal cross-section, and the base is preferably made of PA66+GF35 material, of course, the material is not limited here. The base 3 includes a first support surface 31 and a second support surface 32, and a groove 310 for accommodating the integrated vibration-absorbing and energy-absorbing part for vehicles is formed on the first support surface 31, and the body 1 is inserted into the buckle formed on the base 3 through the clamping part 123 in the second buffer head 120, and the other parts of the body 1 are clamped into the groove 310.

[0048] like Figures 5 and 6 As shown, the first supporting surface 31 includes a supporting member 311 having a normal width and bent upward, the supporting member 311 extends toward the second supporting surface 32 , the vehicle window glass is placed on the supporting member 311 , and the middle portion of the vehicle window glass abuts against the first buffer head 111 .

[0049] like Figure 6 As shown, the normal width of the support member 311 is equal to the shortest distance from the first support surface 31 to the second support surface 32, that is, the thickness of the window glass carried by the base 3 is equivalent to the normal width of the support member 311. At this time, the front and back sides of the window glass are in contact with the first-level energy absorbing block 21 and the second-level energy absorbing block 22, and the bottom of the window glass is relatively fixed. When the window glass shakes or vibrates, the first-level energy absorbing block 21 and the second-level energy absorbing block 22 absorb the vibration waves from the front and back sides of the window glass respectively, that is, the energy absorption directions of the two are opposite, so that the window glass will not be damaged due to vibration force.

[0050] Combination Figure 6 and Figure 8 As shown, the first support surface 31 further includes a protrusion 312 having a normal width and extending in a direction opposite to the support member 311. The protrusion 312 is longitudinally and centrally arranged on the back of the first support surface 31, that is, the protrusion 312 and the support member 311 are respectively located on two sides of the first support surface 31. The protrusion 312 is formed with a wire groove 313 for facilitating the passage of the pull rope and limiting the pull rope.

[0051] like Figure 8As shown, in order to connect the base 3 with the guide rail 4 so that the base 3 can move along the direction of the guide rail 4, a hook 314 is formed on the back of the first support surface 31. The hook 314 is located on one side of the protrusion 312 and is bent toward the protrusion 312. In order to reduce the friction between the hook 314 and the guide rail 4, a shoe-shaped sleeve (not shown in the figure) is clamped in the inner wall of the hook 314. The sleeve is preferably made of POM material, and the sleeve is clamped with the flange of the guide rail 4 and can move on the flange. That is, the hook 314 clamps the base 3 to the guide rail 4 through the sleeve, so that the base 3 moves up and down along the flange.

[0052] like Figures 5 and 6 As shown, the second support surface 32 is N-shaped, and a limiter 321 with a normal width is disposed at the top of the second support surface 32, and the extension direction of the limiter 321 is the same as the extension direction of the protrusion 312, and the limiter 321 is centrally disposed on the second support surface 32. Figure 6 As shown, in the present use novel, the limiting member 321 is preferably made of a material with elastic function such as elastic plastic or silicone, and in order to ensure that the window glass placed in the base 3 is placed stably, the width of the limiting member 321 is preferably equivalent to the width of the supporting member 311; in addition, when the window glass is placed in the base 3, in order to prevent the edges and corners of the limiting member 321 from scratching the window glass, the limiting member 321 is preferably designed to be triangular, and a smooth transition is used between its long side and the waist of the triangle.

[0053] like Fig. 9 As shown, the glass lifter includes the guide rail 4, pulleys 41 arranged at both ends of the guide rail 4, a motor 42 arranged at one side of the guide rail 4 and a wire wheel 43 driven by the motor 42, and any of the above-mentioned glass trays arranged on the guide rail 4. It can be seen that after the motor 42 is started, the motor 42 drives the wire wheel 43 to rotate, and at the same time drives the pull rope wound on the wire wheel 43 to move, and then drives the pulley 41, the base 3 fixed with the pull rope, and the vehicle window glass carried on the base 3 to rise and fall synchronously through the pull rope, so as to realize the automatic lifting and lowering operation of the vehicle window glass.

[0054] There are many implementation methods of the present invention, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
