Description

Technical Field

[0001] The invention belongs to the technical field of automobile windows, and in particular relates to a glass lifter. Background Art

[0002] The glass lift is a device for lifting the glass of car doors and windows. It is mainly divided into two categories: electric glass lift and manual glass lift. Nowadays, the lifting of the glass of many car doors and windows is generally changed to a button-type electric lifting method, using an electric glass lift.

[0003] The electric window lifters for cars are mostly composed of motors, reducers, guide ropes, guide plates, glass mounting brackets, etc. The driver controls the opening and closing of all windows by the master switch, while the passengers control the opening and closing of each window by the sub-switches on the inner handles of each door, which is very convenient to operate.

[0004] Electric glass lifts generally use a motor and a reducer to drive the guide rope to move. The two sides of the guide rope move in the same direction along the guide plate to control the lifting of the glass. This can drive both sides of the glass to lift and lower at the same time. However, this design usually can only lift and lower one side of the glass. When the glass is accidentally broken in an emergency, the safety is greatly reduced. In addition, when damaged, the external view is easily blocked by the damaged part, and it cannot be quickly replaced and used.

[0005] Based on this, the applicant considered designing a window lifter. Summary of the invention

[0006] In view of the above problems, the present invention provides a window lifter that overcomes the above problems or at least partially solves the above problems. The technical solution is as follows:

[0007] A glass lifter comprises a rectangular wheel set, a transmission line, a bearing base, an outer window and an inner window, wherein the rectangular wheel set comprises four rollers arranged in a rectangular surface, the transmission line comprises two opposite side line parts, the transmission line is wound on the rectangular wheel set so that the two side line parts can move up and down at the same time, there are two bearing bases, which are fixedly connected to the two side line parts respectively, the outer window and the inner window are respectively arranged outside the two sides of the rectangular surface of the rectangular wheel set, and the outer window and the inner window are both provided with buckling mechanisms, and both can be connected to the bearing base through the buckling mechanisms, so that the bearing base drives one or more of the outer window and the inner window to move up and down.

[0008] Compared with the prior art, the glass lifter of the present invention has the following advantages:

[0009] By setting up a rectangular wheel set, a transmission line, a bearing base, an outer window, an inner window and a buckling mechanism, the bearing base can choose to drive the outer window and the inner window to move up and down, or move the outer window and the inner window up and down at the same time, so that when a window is accidentally damaged in an emergency, another window can be temporarily and quickly activated for shielding, thereby improving safety and reducing the degree of external vision being blocked due to window damage.

[0010] The above-mentioned glass lifter has the advantages of simple structure and easy implementation, is suitable for installation and use in existing vehicle windows, and has low cost of use, which can improve benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Compared with the prior art, the glass lifter of the present invention has the following advantages:

[0029] By setting up a rectangular wheel set, a transmission line, a bearing base, an outer window 410, an inner window 420 and a buckling mechanism, the bearing base can selectively drive the outer window 410 and the inner window 420 to move up and down, or move the outer window 410 and the inner window 420 up and down at the same time, so that when a window is accidentally damaged in an emergency, another window can be temporarily and quickly activated for shielding, thereby improving safety and reducing the degree of external vision being blocked due to window damage.

[0030] The above-mentioned glass lifter has the advantages of simple structure and easy implementation, is suitable for installation and use in existing vehicle windows, and has low cost of use, which can improve benefits.

[0031] In this embodiment, Figure 1-6 As shown, the supporting base includes a wire connecting body 310 and an external seat 320, the wire connecting body 310 is fixedly connected to the wire edge of the transmission wire, the external seat 320 is fixedly connected to the outer surface of the wire connecting body 310, and the outer window body 410 can be fastened with the external seat 320 through the corresponding fastening mechanism.

[0032] In this way, the movement of the outer window 410 can be controlled by the wire connection body 310 and the external seat 320, and the structure is relatively stable and easy to implement.

[0033] In this embodiment, Figure 1-6 As shown, the fastening mechanism includes a docking body 510, a cylinder 520 and a fastening column 530. The docking body 510 is provided with a telescopic hole on one side facing the external seat 320, and a docking hole corresponding to the telescopic hole is opened on the outer side surface of the external seat 320. The cylinder 520 is arranged in the docking body 510, and the push rod of the cylinder 520 can be telescopically moved along the direction of the telescopic hole. The fastening column 530 is arranged in the telescopic hole and is transmission-connected with the push rod of the cylinder 520. The fastening column 530 can extend into the docking hole when the positions of the telescopic hole and the docking hole are relative.

[0034] In this way, by setting up the docking body 510, the cylinder 520 and the snap-on column 530, the snap-on column 530 can be controlled by the cylinder 520 to extend from the docking body 510 into the corresponding docking hole, so that the supporting base can drive the outer window 410 to move up and down. The docking structure is relatively simple and has high reliability.

[0035] In this embodiment, Figure 1-6 As shown, the bearing base further includes an inner seat 330 , and the inner seat 330 is fixedly connected to the inner side surface of the line connecting body 310 , and the inner window 420 can be buckled with the inner seat 330 through the corresponding buckling mechanism.

[0036] In this way, by providing the inner seat 330, the movement of the inner window 420 can be controlled through the corresponding buckling mechanism, and the structure is relatively stable and easy to implement.

[0037] In this embodiment, Figure 1-6 As shown, the locking mechanism includes a docking body 510, a cylinder 520 and a locking column 530. The docking body 510 is provided with a telescopic hole on one side facing the inner seat 330, and a docking hole corresponding to the telescopic hole is opened on the outer side of the inner seat 330. The cylinder 520 is arranged in the docking body 510, and the push rod of the cylinder 520 can be telescopically moved along the direction of the telescopic hole. The locking column 530 is arranged in the telescopic hole and is transmission-connected with the push rod of the cylinder 520. The locking column 530 can extend into the docking hole when the positions of the telescopic hole and the docking hole are relative.

[0038] In this way, by setting up the docking body 510, the cylinder 520 and the snap-on column 530, the snap-on column 530 can be controlled by the cylinder 520 to extend from the docking body 510 into the corresponding docking hole, so that the supporting base can drive the inner window 420 to move up and down. The docking structure is relatively simple and has high reliability.

[0039] In this embodiment, Figure 1-6As shown, it also includes an outer slide rail 610, which is arranged between the upper and lower rollers 100 located at the edge portion 200 in the rectangular wheel group. The bearing base is slidably arranged in the outer slide rail 610 and can move up and down along the outer slide rail 610.

[0040] In this way, by setting the outer slide rail 610, the supporting base can move along the direction of the outer slide rail 610, thereby increasing the stability of the supporting base during movement, thereby improving the stability of the inner window 420 and the outer window 410 during movement.

[0041] In this embodiment, Figure 1-6 As shown, a connecting plate 620 is disposed on the top of the outer slide rail 610 , a through hole 630 is disposed on the connecting plate 620 , and the transmission line is passed through the through hole 630 .

[0042] In this way, the track walls on both sides of the outer slide rail 610 can be connected by the connection plate 620, and the through hole 630 can allow the transmission line to pass through. The structure is simple and ingenious and easy to implement.

[0043] In this embodiment, Figure 1-6 As shown, the transmission line also includes a first center line 710 and a second center line 720 that are arranged to cross each other. The upper end of one side line portion 200 is connected to one end of the first center line 710, and the lower end is connected to one end of the second center line 720. The upper end of the other side line portion 200 is connected to the other end of the second center line 720, and the lower end is connected to the other end of the first center line 710. The first center line 710 is connected to a power mechanism for driving the transmission line to move around the rectangular wheel set.

[0044] In this way, by cross-setting the first center line 710 and the second center line 720, the transmission line can make the two side line parts 200 rise or fall at the same time during movement, so as to simultaneously drive the two ends of the inner window 420 or the outer window 410 to move, and the balance is better.

[0045] In this embodiment, Figure 1-6 As shown, the transmission mechanism includes a fixed plate 810, a motor 820, a worm 830, a worm wheel 840 and a transmission roller 850. The fixed plate 810 is fixedly arranged below the first center line 710, the motor 820 is arranged on the fixed plate 810, the worm 830 is coaxially connected to the rotating shaft of the motor 820, the worm wheel 840 is arranged above the worm 830 and is transmission connected to the worm 830, the transmission roller 850 is coaxially connected to the side of the worm wheel 840, and the transmission line is wound around the transmission roller 850.

[0046] In this way, by setting the fixed plate 810, motor 820, worm 830, worm wheel 840 and transmission roller 850, the transmission roller 850 can be driven to rotate by the motor 820 to drive the transmission line to move, and because the worm wheel 840 and worm 830 cooperate with each other, reverse transmission is impossible, thereby improving the anti-theft performance of the vehicle window.

[0047] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
