Referring to FIG. 1, the present application provides a vehicle 100. The vehicle 100 may include, but is not limited to, passenger cars, multi-purpose vehicles (MPVs), sport/suburban utility vehicles (SUVs), off-road vehicles (ORVs), pickup trucks, minivans, passenger cars, trucks, and the like.

The automobile 100 includes a body assembly 300 and a glass assembly 200 as described in any of the following embodiments. The glass assembly 200 is attached to the body assembly 300.

Body assembly 300 is at least a portion of automobile 100 or includes at least some structural and electronic components of automobile 100. For example, body assembly 300 can include a frame, floor panels, transmission, seats, center console panels, etc.

Referring to Figures 2 to 4, the present application further provides a glass assembly 200. The glass assembly 200 includes a liftable automobile door glass 5 and a wire harness structure 400 as described in any of the following embodiments. The wire harness structure 400 includes a first wire harness 11. A first end of the first wire harness 11 is connected to the automobile door glass 5.

The connection between the automobile door glass 5 and the first end of the first wire harness 11 is an electrical connection, and the connection may be a non-removable connection or a removable connection (for example, the automobile door glass 5 and the first end are electrically connected in a removable manner by a connector).

The glass assembly 200 has a first state and a second state. When the glass assembly 200 is in the first state, the automobile door glass 5 is in the lowest position, as shown in Figures 2 and 3. When the glass assembly 200 is in the second state, the automobile door glass 5 is in the highest position, as shown in Figure 4. Please refer to the description herein for the following description of the first state and the second state.

The wire harness structure 400 included in the glass assembly 200 according to the above embodiment will be described in detail below with reference to the drawings.

Referring to FIG. 5 in conjunction with FIGS. 2 to 4, the present application further provides a wire harness structure 400. The wire harness structure 400 includes a fixture assembly 3, a first wire harness 11, and a traction mechanism 2.

The fixture assembly 3 is fixed to the vehicle body assembly 300.

The first wire harness 11 includes a first end and a second end. The first end of the first wire harness 11 is configured to be connected to a vehicle door glass 5 that can be raised and lowered. When the vehicle door glass 5 rises and lowers, the first end of the first wire harness 11 correspondingly rises and lowers together with the vehicle door glass 5, driving the movement of the first wire harness 11. The second end of the first wire harness 11 is configured to be connected to a fixture assembly 3 so as to be fixed to a vehicle body assembly 300 via the fixture assembly 3.

The traction mechanism 2 is configured to have one end connected to the vehicle body assembly 300 so as to be fixed to the vehicle body assembly 300. The other end of the traction mechanism 2 is configured to be connected between the first end and the second end of the first wire harness 11 so that the first wire harness 11 is in a folded state and the first wire harness is tensioned.

In the related art, the first end of the first wire harness 11 is fixed to the automobile door glass 5, and the second end is fixed to the vehicle body assembly 300 via the fixture assembly 3. The portion between the first end and the second end (hereinafter referred to as the middle portion) is in a free state, that is, the middle portion can move freely. In the process in which the automobile door glass 5 drives the movement of the first end, or while the automobile 100 is running, the middle portion is affected and begins to shake, resulting in problems such as clogging of the middle portion and generation of abnormal noise. Therefore, the middle portion lacks stable movement trajectory control, and the display function, power function, etc. of the automobile door glass 5 are also affected.

In the present application, one end of the traction mechanism 2 is connected between the first end and the second end of the first wire harness 11, so that the first wire harness 11 is in a tensioned state. In other words, the traction mechanism 2 is used to strongly pull the first wire harness 11. The first wire harness 11 in a tensioned state will not swing freely due to external influences, so problems such as clogging of the first wire harness 11 and generation of abnormal noise can be avoided.

2 to 4, and referring to FIG. 5, the wire harness structure 400 further includes a second wire harness 12 and a control device assembly 4. The second wire harness 12 has one end connected to the fixture assembly 3 and is electrically connected to the first wire harness 11. In one embodiment, the fixture assembly 3 is an intermediary for the electrical connection of the first wire harness 11 and the second wire harness 12, i.e., both the first wire harness 11 and the second wire harness 12 are electrically connected to the fixture assembly 3, and the electrical connection can be realized by, but is not limited to, a connector. In another embodiment, the first wire harness 11 and the second wire harness 12 may be directly connected, i.e., the fixture assembly 3 only performs the function of fixing the first wire harness 11 and the second wire harness 12, and is not electrically connected to the first wire harness 11 and the second wire harness 12. Of course, there are other embodiments, which will not be described in detail here.

Furthermore, the other end of the second wire harness 12 is electrically connected to the control device assembly 4. Thereby, the control device assembly 4 is electrically connected to the automobile door glass 5, and the automobile door glass 5 has a corresponding function (e.g., a display function), and the control device assembly 4 can control the automobile door glass 5 to display the time, weather conditions, navigation route, etc. Of course, the above is only an exemplary description, and the automobile door glass 5 may have other functions, and is not limited in this application.

Referring to FIG. 4, the traction mechanism 2 includes a pulley assembly 21, a return member 22, and a support frame 23.

The pulley assembly 21 is movably connected to the first wire harness 11, that is, the pulley assembly 21 and the first wire harness 11 can move relative to each other. Specifically, when the automobile door glass 5 is in a different position, the contact position between the pulley assembly 21 and the first wire harness 11 is different. In the process of the glass assembly 200 switching from the first state to the second state, the automobile door glass 5 gradually rises and drives the pulley assembly 21 to rise, and the pulley assembly 21 gradually approaches the second end of the first wire harness 11 during the rise. In the process of the glass assembly 200 switching from the second state to the first state, the automobile door glass 5 gradually descends and drives the pulley assembly 21 to descend, and the pulley assembly 21 gradually approaches the first end of the first wire harness 11 during the descend.

The support frame 23 is configured to be connected to the vehicle body assembly 300 so as to be fixed to the vehicle body assembly 300. Note that the connection between the support frame 23 and the vehicle body assembly 300 may be a removable connection or a non-removable connection.

The return member 22 has one end connected to the pulley assembly 21. The other end of the return member 22 is connected to the support frame 23. The return member 22 is configured to pull the pulley assembly 21 tightly so that the first wire harness 11 is always in a taut state.

Furthermore, the return member 22 has elasticity. Below, we will explain the role that the characteristics of the return member 22 itself play when the automobile door glass 5 is raised and lowered.

In the process of the glass assembly 200 switching from the first state to the second state (i.e., the automobile door glass 5 rising from the lowest point to the highest point), the first wire harness 11 drives the rise of the pulley assembly 21, and the pulley assembly 21 gradually stretches the return member 22 during the rise, and correspondingly, the return member 22 generates a restoring force in the opposite direction to the rising direction of the pulley assembly 21, so that the first wire harness 11 keeps a tendency to be pulled back and descend. As a result, the first wire harness 11 is always in a taut state and does not swing. In the process of the glass assembly 200 switching from the second state to the first state (i.e., the automobile door glass 5 descends from the highest point to the lowest point), the pulley assembly 21 descends, and the return member 22 itself has a restoring force to restore to its original shape, so the return member 22 gradually shortens and strongly pulls the pulley assembly 21 in the downward direction of the pulley assembly 21. As a result, the first wire harness 11 remains taut at all times and does not swing.

Optionally, when the glass assembly 200 is in the first state, the restoring force generated by the return member 22 is greater than 0. That is, when in the first state, the return member 22 is already stretched, and it can be ensured that the first wire harness 11 is in a taut state all the time. Of course, in another embodiment, when the glass assembly 200 is in the first state, the restoring force generated by the return member 22 may be equal to 0.

Optionally, the return member 22 is an expandable elastic member, such as a spring or a constant force spring.

Optionally, the return member 22 is a spiral spring, which is wound around the support frame 23. The spiral spring is wound integrally around the axis, allowing it to be stored and occupy less space. The spiral spring can be, but is not limited to, a constant force spiral spring. The constant force spiral spring can provide a constant tension to the pulley assembly 21, so that the first wire harness 11 is always in tension.

In the embodiment of the present application, the return member 22 is described as being a spiral spring by way of example, but the specific type is not limited.

Referring to FIG. 5, the fixture assembly 3 includes a bracket 31 and a connection case 32 connected to each other. The connection case 32 is connected to the first wire harness 11 and the second wire harness 12. The bracket 31 is configured to be connected to the vehicle body assembly 300, thereby realizing that the fixture assembly 3 is fixed to the vehicle body assembly 300. Note that the connection between the bracket 31 and the vehicle body assembly 300 may be a removable connection, such as a connection by a screw fastener. The connection may be a non-removable connection, such as a soldering connection.

The support frame 23 included in the wire harness structure 400 will be described in detail below with reference to the drawings.

Referring to FIG. 6, the support frame 23 includes a rotating shaft 231 and a support stand 232. The support stand 232 is configured to be connected to the vehicle body assembly 300. The connection may be, but is not limited to, a connection by a screw fastener, a rivet, or soldering. The rotating shaft 231 is rotatably connected to the support stand 232, i.e., the rotating shaft 231 can rotate relative to the support stand 232. The restoring member 22 is wound around the rotating shaft 231. During the raising and lowering of the automobile door glass 5, the restoring member 22 drives the rotation of the rotating shaft 231 to realize the extension and contraction of the restoring member 22.

6 and 7, the support stand 232 includes a first support portion 2321, a second support portion 2322, and a connection portion 2323. The first support portion 2321 and the second support portion 2322 are disposed opposite each other and connected to the connection portion 2323. The connection portion 2323 is configured to be connected to the vehicle body assembly 300, thereby realizing that the support stand 232 is fixed to the vehicle body assembly 300. As shown in FIG. 7, the first support portion 2321 has a first hole K1, and the second support portion 2322 has a second hole K2. The first hole K1 and the second hole K2 are disposed opposite each other. The rotation shaft 231 passes through the first hole K1 and the second hole K2. That is, the opposing ends of the rotating shaft 231 are supported by the first support part 2321 and the second support part 2322, respectively, so that the rotating shaft 231 can have good rotational stability.

6 and 7, the rotating shaft 231 includes a rotating shaft main body 2311 and a first position limiting disk 2312. The shaft diameter of the rotating shaft main body 2311 is equal to or smaller than the hole diameters of the first hole K1 and the second hole K2, and the rotating shaft main body 2311 passes through the first hole K1 and the second hole K2. The first position limiting disk 2312 is connected to surround the outer periphery of the rotating shaft main body 2311, and is on one side of the second support part 2322 away from the first support part 2321. The outer diameter of the first position limiting disk 2312 is larger than the hole diameter of the second hole K2. In other words, due to the presence of the first position limiting disk 2312, the rotating shaft 231 cannot pass through the second hole K2 (i.e., cannot come out of the second hole K2) , and the movement of the rotating shaft 231 is limited in the direction from the second hole K2 to the first hole K1.

7, a first annular groove C1 is disposed at one end of the rotating shaft main body 2311 far from the first position limiting disk 2312. The first annular groove C1 is on one side of the first support part 2321 away from the second support part 2322. The support frame 23 further includes a first annular member 233. At least a portion of the first annular member 233 is disposed in the first annular groove C1. The outer diameter of the first annular member 233 is larger than the hole diameter of the first hole K1. In other words, due to the presence of the first annular member 233, the rotating shaft 231 cannot pass through the first hole K1 (i.e., cannot come out of the first hole K1) , and the movement of the rotating shaft 231 is limited in the direction from the first hole K1 to the second hole K2.

The pulley assembly 21 included in the wire harness structure 400 will be described in detail below with reference to the drawings.

8, the pulley assembly 21 includes a pulley stand 211 and a pulley body 212 connected to each other. The pulley stand 211 is connected to the return member 22. The pulley body 212 and the pulley stand 211 form a clearance space C3. The first wire harness 11 passes through the clearance space C3 and is pressed against the pulley body 212. During the raising and lowering of the automobile door glass 5, the clearance space C3 provides a space for the pulley assembly 21 and the first wire harness 11 to move relative to each other. As can be seen from the above embodiment, when the automobile door glass 5 is in different positions, the contact position between the pulley assembly 21 and the first wire harness 11 is different. In this embodiment, when the glass assembly 200 switches between the first state and the second state, the pulley body 212 moves between the first end and the second end of the first wire harness 11. Note that the relative movement between the pulley assembly 21 and the first wire harness 11 may be sliding or rolling.

Referring to FIG. 8, the pulley body 212 is rotatably connected to the pulley stand 211. When the first end of the first wire harness 11 moves together with the automobile door glass 5, the first wire harness 11 can drive the rotation of the pulley body 212. That is, the first wire harness 11 drives the pulley body 212 with frictional force, so that the pulley body 212 rotates relative to the pulley stand 211. Because the pulley body 212 can rotate, rolling friction occurs between the pulley body 212 and the first wire harness 11 during the relative movement, which can reduce wear.

Optionally, the first wire harness 11 is a flat wire harness. The design of the flat wire harness can increase the contact area between the first wire harness 11 and the pulley body 212, making it easier for the first wire harness 11 to drive the rotation of the pulley body 212.

8 and 9, the pulley stand 211 includes a first support portion 2111, a second support portion 2112, and an intermediate portion 2113. The first support portion 2111 and the second support portion 2112 are arranged opposite to each other and are bent and connected to the intermediate portion 2113. As shown in FIG. 9, the first support portion 2111 has a first through hole K3, and the second support portion 2112 has a second through hole K4. The first through hole K3 and the second through hole K4 are arranged opposite to each other. The pulley body 212 passes through the first through hole K3 and the second through hole K4. That is, the opposing ends of the pulley body 212 are supported by the first support portion 2111 and the second support portion 2112, respectively, so that the pulley body 212 can have good connection stability and can further ensure that the first wire harness 11 is always in a taut state. In addition, the pulley body 212 and the intermediate portion 2113 together form a gap C3. That is, the pulley body 212 and the intermediate portion 2113 are disposed opposite each other at a distance to form the gap C3. The first wire harness 11 passes through the gap C3.

Referring to FIG. 8, the pulley stand 211 further includes an extension 2114. One end of the extension 2114 is connected to one side of the intermediate portion 2113 away from the pulley body 212, and the other end of the extension 2114 is connected to the return member 22. In other words, the pulley assembly 21 is connected to the return member 22 via the extension 2114. The connection can be, but is not limited to, a connection by soldering, rivets, or screw fasteners.

8 and 9, the pulley body 212 includes a pulley main body 2123 and a second position limiting disk 2124. The shaft diameter of the pulley main body 2123 is equal to or smaller than the hole diameter of the first through hole K3 and the hole diameter of the second through hole K4, and the pulley main body 2123 passes through the first through hole K3 and the second through hole K4. The second position limiting disk 2124 is connected to surround the outer periphery of the pulley main body 2123. The second position limiting disk 2124 is on one side of the second support part 2112 away from the first support part 2111. The outer diameter of the second position limiting disk 2124 is larger than the hole diameter of the second through hole K4. In other words, due to the presence of the second position limiting disk 2124, the pulley body 212 cannot pass through the second through hole K4 (i.e., cannot come out of the second through hole K4) , and the movement of the pulley body 212 is limited to the direction from the second through hole K4 toward the first through hole K3.

9, a second annular groove C2 is disposed at one end of the pulley main body 2123 far from the second position limiting disk 2124. The second annular groove C2 is on one side of the first support part 2111 away from the second support part 2112. The pulley assembly 21 further includes a second annular member 213. At least a portion of the second annular member 213 is disposed in the second annular groove C2. The outer diameter of the second annular member 213 is larger than the hole diameter of the first through hole K3. In other words, due to the presence of the second annular member 213, the pulley body 212 cannot pass through the first through hole K3 (i.e., cannot come out of the first through hole K3) , and the movement of the pulley body 212 is limited in the direction from the first through hole K3 to the second through hole K4.

Referring to FIG. 10, optionally, the pulley body 212 includes a rotating shaft 2121 and a shaft sleeve 2122. The rotating shaft 2121 is rotatably connected to the pulley stand 211. The shaft sleeve 2122 is sleeved on the outer circumference of the rotating shaft 2121. The first wire harness 11 is pressed against the shaft sleeve 2122. The shaft sleeve 2122 is deformed by the pressing of the first wire harness 11. The shaft sleeve 2122 is made of a material that is easily deformed. The shaft sleeve 2122 can be, but is not limited to, a rubber belt or a rubber sleeve. By the deformation of the shaft sleeve 2122, the first wire harness 11 and the shaft sleeve 2122 are in sufficient contact with each other, the frictional force between them is increased, and the first wire harness 11 is easily able to drive the rotation of the pulley body 212, and the sliding between the first wire harness 11 and the pulley can be avoided.

Although the embodiments of the present application have been shown and described above, the above embodiments are illustrative and should not be understood as limiting the present application. Those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application. These improvements and embellishments should also fall within the scope of protection of the present application.
