Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and more specifically, to a window regulator, a car door, and a car. Background Technology

[0002] Car door windows can be mechanically raised and lowered using window regulators. With the development of automotive intelligence, people have increasingly higher demands for the technological feel of vehicles, no longer satisfied with simple window raising and lowering. As a result, dimming and touchscreen windows have gained widespread attention. Compared to ordinary car door windows, one of the key aspects of dimming and touchscreen-enabled car door windows is achieving electrical connection to the window. However, car door windows are moving parts, making the wiring harness connection and installation difficult, prone to causing abnormal noises and motion interference. Summary of the Invention

[0003] The present invention aims to solve the technical problem that the connection between the existing car door glass and the wiring harness is difficult and prone to motion interference.

[0004] In a first aspect, the present invention proposes a window regulator, comprising a first guide rail, a first slider, and a steel wire rope. The first guide rail includes a first guide rail body and a first insert, a wire, and a brush disposed on the first guide rail body. The first slider includes a first slider body and a second insert disposed on the first slider body. The first slider body is used to install a car door glass and is slidably disposed on the first guide rail body. The first insert is used to connect to a vehicle body wiring harness. One end of the wire is connected to the first insert, and the other end of the wire is connected to the brush. One end of the steel wire rope is connected to the second insert to drive the first slider body to slide relative to the first guide rail body. The steel wire rope is slidably connected to the brush, and the second insert is used to electrically connect to the car door glass.

[0005] The glass lifter described in this invention has at least the following advantages compared to the prior art:

[0006] On one hand, the door glass can be fixed to the first slider body, and the steel wire rope is connected to the second plug on the first slider body. Pulling the steel wire rope can drive the first slider body to move relative to the first guide rail body, thereby realizing the up and down lifting of the door glass. On the other hand, one end of the first plug can be connected to the automotive wiring harness, and the other end of the first plug is connected to the brush via a wire. The brush can slide relative to the steel wire rope. The automotive power is sequentially transmitted to the first plug, the wire, the brush, and the steel wire rope, and then transmitted to the second plug via the steel wire rope. The second plug is electrically connected to the door glass to realize the conduction of automotive power to the door glass. Since the first plug, the wire, and the brush are respectively arranged on the first guide rail body, and the second plug is arranged on the first slider body, the first plug, the wire, the brush, the steel wire rope, and the second plug constitute an electrical conduction structure.

The pressure plate of the negative brush is used to limit the second steel wire rope from deviating from the corresponding brush body.

[0012] Optionally, the window regulator further includes a second guide rail, a second slider, and a wire rope winding mechanism.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fitting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] In addition, it should be noted that in the description of the present invention, terms such as "upper," "lower," "front," and "rear" used to indicate orientation in various embodiments are only for simplifying the description of the positional relationships based on the accompanying drawings and do not mean that the elements and devices referred to must be operated in accordance with the specific orientation and limited operation, method, and structure in the specification. Such directional terms do not constitute a limitation on the present invention.

[0027] This paper establishes a coordinate system XZ, where the positive direction of the X-axis represents the front, the negative direction of the X-axis represents the rear, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom. It should be noted that this system is only used to illustrate the orientation and does not limit the scope of protection of this invention.

[0028] like Figure 2-4 As shown, this embodiment of the invention provides a window regulator, including a first guide rail 1, a first slider 2, and a steel wire rope. The first guide rail 1 includes a first guide rail body 11 and a first insert 12, a wire 13, and a brush 14 disposed on the first guide rail body 11. The first slider 2 includes a first slider body 21 and a second insert 22 disposed on the first slider body 21. The first slider body 21 is used to install the door glass and is slidably disposed on the first guide rail body 11. The first insert 12 is used to connect to the vehicle body wiring harness. One end of the wire 13 is connected to the first insert 12, and the other end of the wire 13 is connected to the brush 14. One end of the steel wire rope is connected to the second insert 22 to drive the first slider body 21 to slide relative to the first guide rail body 11. The steel wire rope is slidably connected to the brush 14. The second insert 22 is used to electrically connect to the door glass.

[0029] Specifically, the first guide rail body 11 extends along the Z-axis, the first plug-in 12 can be installed in the middle of the first guide rail body 11, and the brush 14 can be located at the end of the first guide rail body 11 to facilitate sliding contact with the wire rope. The first slider body 21 can be provided with a groove extending along the Z-axis. The first slider body 21 moves along the Z-axis with the first guide rail body 11 through the groove. The first slider body 21 can be bonded and fixed to the door glass. The first plug-in 12 and the second plug-in 22 are electrical connectors, which connect two power lines or data lines together to transmit power or electronic data. Both the first plug-in 12 and the second plug-in 22 have voltage and current input terminals and output terminals.

[0030] In this embodiment, the steel wire rope is connected to the second plug-in 22 on the first slider body 21. Pulling the steel wire rope can cause the first slider body 21 to move relative to the first guide rail body 11, thereby realizing the up and down lifting of the car door glass. On the other hand, one end of the first plug-in 12 is connected to the automotive wiring harness, and the other end of the first plug-in 12 is connected to the brush 14 via the wire 13. The brush 14 can slide relative to the steel wire rope. The automotive power is sequentially transmitted to the first plug-in 12, the wire 13, the brush 14, and the steel wire rope, and then transmitted to the second plug-in 22 via the steel wire rope. The plug 22 is electrically connected to the door glass to conduct the car's power to the door glass. Since the first plug 12, wire 13 and brush 14 are respectively arranged on the first guide rail body 11, and the second plug 22 is arranged on the first slider body 21, the first plug 12, wire 13, brush 14, wire rope and second plug 22 constitute an electrical conduction structure. The glass regulator of the present invention realizes the integration of an electrical conduction structure on a traditional glass regulator. Not only is the wiring harness connection convenient and there is no motion interference, but the integration of the glass regulator is also higher.

[0031] It should be noted that a window regulator generally includes a guide rail, a slider, and a steel cable. The slider is slidably mounted on the guide rail, and the door glass is fixedly connected to the slider. The steel cable is connected to a steel cable winding mechanism. The rotation of the steel cable winding mechanism causes the steel cable to tighten or loosen, thereby driving the slider to rise or fall, and thus realizing the up and down movement of the door glass.

[0032] like Figure 3 As shown, optionally, the conductor 13 includes a positive wire 131 and a negative wire 132, the brush 14 includes a positive brush 141 and a negative brush 142, the positive brush 141 and the negative brush 142 are respectively disposed at both ends of the first guide rail body 11, the wire rope includes a first wire rope 3 and a second wire rope 4, one end of the positive wire 131 is connected to the positive output terminal of the first plug-in 12, the other end of the positive wire 131 is connected to the positive brush 141, the positive brush 141 is connected to the positive input terminal of the second plug-in 22 through the first wire rope 3, one end of the negative wire 132 is connected to the negative output terminal of the first plug-in 12, the other end of the negative wire 132 is connected to the negative brush 142, and the negative brush 142 is connected to the negative input terminal of the second plug-in 22 through the second wire rope 4.

[0033] Specifically, the output terminal of the first plug-in 12 includes a positive output terminal and a negative output terminal, and the input terminal of the second plug-in 22 includes a positive input terminal and a negative input terminal. The lower end of the positive wire 131 is connected to the positive output terminal of the first plug-in 12, and the upper end of the positive wire 131 extends upward along the Z-axis and is connected to the positive brush 141 on the upper end of the first guide rail body 11. The positive brush 141 can be embedded in the first guide rail body 11 to transfer the electricity on the positive wire 131 to the first steel wire rope 3. One end of the first steel wire rope 3 can be wound upward around the upper end of the first guide rail body 11 to connect to the positive input terminal of the second plug-in 22 on the first slider body 21.

[0034] The upper end of the negative wire 132 is connected to the negative output terminal of the first plug-in 12. The lower end of the negative wire 132 extends downward along the Z-axis and is connected to the negative brush 142 at the lower end of the first guide rail body 11. The negative brush 142 can be embedded in the first guide rail body 11 so that the electricity on the negative wire 132 can be transferred to the second steel wire rope 4 through the negative brush 142. One end of the second steel wire rope 4 can be wrapped around the lower end of the first guide rail body 11 to be connected to the negative input terminal of the second plug-in 22 on the first slider body 21.

[0035] In this embodiment, the positive wire 131 and the negative wire 132 extend along the direction shown by the Z-axis, which can save wire length while achieving electrical conduction. The positive and negative terminals of the output end of the first plug-in 12 are connected to the positive and negative brushes through the positive and negative wires, respectively, and the electrical conductivity of the first and second steel wires is used to conduct electricity to the positive and negative terminals of the input end of the second plug-in 22.

[0036] like Figure 4 As shown, optionally, the first slider 2 further includes a positive terminal 23 and a negative terminal 24. The positive terminal 23 is located at one end of the first steel wire rope 3 and is connected to the positive input terminal of the second plug-in 22. The negative terminal 24 is located at one end of the second steel wire rope 4 and is connected to the negative input terminal of the second plug-in 22.

[0037] In this embodiment, the positive terminal 23 and the negative terminal 24 can be cylindrical terminals. The positive terminal 23 can be welded and fixed to the first steel wire rope 3. The positive terminal 23 can conduct the positive current on the first steel wire rope 3 to the positive input terminal of the second plug-in 22. The connection and principle of the negative terminal 24 are similar to those described above and will not be repeated. Positive and negative markings can be provided on the positive terminal 23 and the negative terminal 24 for easy differentiation. Alternatively, the positive terminal 23 and the negative terminal 24 can use different colored terminals for differentiation.

[0038] like Figure 6 As shown, optionally, the positive input terminal of the second plug-in 22 is provided with a first slot 221, and the positive terminal connector 23 is inserted into the first slot 221. The negative input terminal of the second plug-in 22 is provided with a second slot 222, and the negative terminal connector 24 is inserted into the second slot 222.

[0039] In this embodiment, the first slot 221 can be a U-shaped slot, and its size can be designed to match the size of the positive terminal 23. The second slot 222 can also be a U-shaped slot, and its size can be designed to match the size of the negative terminal 24. The output end of the second plug-in 22 can be equipped with a pin 223, which is electrically connected to the door glass. Here, the pin can output positive and negative voltage and current.

[0040] Optionally, both the first guide rail body 11 and the first slider body 21 are made of insulating material.

[0041] In this embodiment, the wire 13 can be embedded inside the first guide rail body 11 and can be formed together with the first guide rail body 11. The first guide rail body 11 not only serves to support the wire 13, but also to protect the wire 13 and prevent the wire 13 from interfering with other components.

[0042] Here, the first guide rail body 11 and the first slider body 21 are both made of insulating material, so that the car power can only be conducted to the second plug-in 22 through the first plug-in 12, wire 13, brush 14 and steel wire rope, avoiding electrical conduction disorder.

[0043] like Figure 5 As shown, optionally, both the positive brush 141 and the negative brush 142 include a brush body 1431 and a pressure plate 1432 disposed opposite to each other. The positive wire 131 is connected to the brush body 1431 of the positive brush 141. The first steel wire rope 3 passes through the brush body 1431 of the positive brush 141 and the pressure plate 1432. The pressure plate 1432 of the positive brush 141 is used to limit the first steel wire rope 3 from deviating from the corresponding brush body 1431. The negative wire 132 is connected to the brush body 1431 of the negative brush 142. The second steel wire rope 4 passes through the brush body 1431 of the negative brush 142 and the pressure plate 1432. The pressure plate 1432 of the negative brush 142 is used to limit the second steel wire rope 4 from deviating from the corresponding brush body 1431.

[0044] Specifically, the positive brush 141 and the negative brush 142 have the same structure, only differing in their placement. The positive brush 141 will be used as an example for explanation. The upper end of the first guide rail body 11 is provided with a mounting groove. The brush body 1431 of the positive brush 141 is located at the bottom of the mounting groove. A pressure plate 1432 is provided at the opening of the mounting groove. The cross-sectional dimension of the pressure plate 1432 may be slightly larger than that of the brush body 1431. A slot is formed between the pressure plate 1432 and the brush body 1431 to allow the first steel wire rope 3 to pass through. The first steel wire rope 3 can contact the pressure plate 1432 and the brush body 1431.

[0045] In this embodiment, the first steel wire rope 3 is pressed against the brush body 1431 by the pressure plate 1432 to prevent the first steel wire rope 3 from detaching from the brush body 1431 due to shaking during the tensioning and relaxation process, thus ensuring a good connection between the first steel wire rope 3 and the brush body 1431, so that electricity can be smoothly conducted from the positive brush 141 to the first steel wire rope 3.

[0046] like Figure 1 As shown, optionally, the window regulator further includes a second guide rail 5, a second slider 6, and a wire rope winding mechanism 7. The second guide rail 5 includes a second guide rail body 51, which is opposite to and parallel to the first guide rail body 11. The second slider 6 is slidably disposed on the second guide rail body 51. The door glass is used to be installed between the first slider body 21 and the second slider 6. The wire rope winding mechanism 7 is drivenly connected to the first wire rope 3. The first wire rope 3 and the second wire rope 4 are arranged in a cross configuration. The two ends of the first wire rope 3 are respectively connected to the positive input terminal of the second plug-in 22 and the first position of the second slider 6. The two ends of the second wire rope 4 are respectively connected to the negative input terminal of the second plug-in 22 and the second position of the second slider 6.

[0047] Specifically, the second guide rail body 51 and the first guide rail body 11 are spaced apart along the X-axis. The second slider 6 may be provided with a groove extending along the Z-axis to slide and connect with the second guide rail body 51 through the groove. The wire rope winding mechanism 7 may include a drive motor and a winding wheel. The drive motor is driven and connected to the winding wheel. The middle part of the first wire rope 3 passes around the winding wheel.

[0048] In this embodiment, the door glass is simultaneously connected to both the first slider body 21 and the second slider 6, improving the stability between the door glass and the window regulator. The window regulator can drive the door glass to rise and fall stably along the Z-axis. The forward and reverse rotation of the drive motor drives the winding wheel to rotate, causing one end of the first steel wire rope 3 to be tensioned while the other end is relaxed. For example, when the drive motor rotates forward, the end of the first steel wire rope 3 connected to the first slider 2 is tensioned, while the end connected to the second slider 6 is relaxed. At this time, the first slider body 21 moves upward relative to the first guide rail body 11, and the second slider 6 moves upward relative to the second guide rail body 51. Both sliders rise simultaneously, causing the door glass to rise. The principle of the drive motor rotating in the reverse direction to drive the door glass downward is similar and will not be repeated.

[0049] It should be noted that the portions of the first wire rope 3 and the second wire rope 4 located between the first guide rail body 11 and the second guide rail body 51 can be fitted with protective sleeves to prevent friction damage to the wire ropes during movement.

[0050] like Figure 1 , 3 As shown, optionally, the first guide rail 1 further includes two first guide wheels 15 respectively disposed at both ends of the first guide rail body 11, and the second guide rail 5 further includes two second guide wheels 52 respectively disposed at both ends of the second guide rail body 51. One end of the first wire rope 3 passes over one of the first guide wheels 15 to connect to the positive input terminal of the second plug-in 22, and the other end of the first wire rope 3 passes over one of the second guide wheels 52 to connect to the first position of the second slider 6. One end of the second wire rope 4 passes over the other first guide wheel 15 to connect to the negative input terminal of the second plug-in 22, and the other end of the second wire rope 4 passes over the other second guide wheel 52 to connect to the second position of the second slider 6.

[0051] Specifically, the axis of the first guide wheel 15 is perpendicular to the XZ plane. The two first guide wheels 15 are located at the uppermost and lowermost ends of the first guide rail body 11, respectively. The Z-axis height of the positive brush 141 is less than the height of the upper first guide wheel, and the Z-axis height of the negative brush 142 is greater than the height of the lower first guide wheel. That is, the two brushes are located between the two first guide wheels. The positive brush 141 and the negative brush 142 are arranged closer to the side of the second guide rail body 51. The axis of the second guide wheel 52 is perpendicular to the XZ plane. The two second guide wheels 52 are located at the uppermost and lowermost ends of the second guide rail body 51, respectively. At the top and bottom; one end of the first steel wire rope 3 passes through the positive brush 141, then passes around the first guide wheel 15 above the first guide rail body 11 to connect with the positive input terminal of the second plug-in 22, and the other end of the first steel wire rope 3 passes around the second guide wheel 52 below the second guide rail body 51 to connect with the second slider 6; one end of the second steel wire rope 4 passes through the negative brush 142, then passes around the first guide wheel 15 below the first guide rail body 11 to connect with the negative input terminal of the second plug-in 22, and the other end of the second steel wire rope 4 passes around the second guide wheel 52 above the second guide rail body 51 to connect with the second slider 6.

[0052] In this embodiment, first guide wheels 15 are respectively set at the two ends of the first guide rail body 11, and second guide wheels 52 are respectively set at the two ends of the second guide rail body 51. The first guide wheels 15 and the second guide wheels 52 guide the direction of the first wire rope 3 and the second wire rope 4, so that the first wire rope 3 and the second wire rope 4 apply a tension force along the Z-axis to the first slider body 21 and the second slider 6.

[0054] Another embodiment of the present invention provides a car including the aforementioned car door. The advantages of this car compared to the prior art are the same as those of the aforementioned car door, and will not be repeated here.

[0055] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
