Description

Technical Field

[0001] This application relates to the field of automotive window technology, and in particular to a sliding window assembly and a vehicle. Background Technology

[0002] The rear windshields of some vehicles, such as pickup trucks, are composed of sliding window assemblies. These assemblies consist of a fixed glass pane and a sliding glass pane. The sliding glass pane can slide relative to the fixed glass to open or close the window located on the fixed glass pane, meeting various usage needs. Some sliding window assemblies have heating wires on both the sliding and fixed glass panes to achieve a defrosting effect. These heating wires on the sliding glass pane require power via connecting cables. However, in traditional sliding window assemblies, the movement of the sliding glass relative to the fixed glass can easily damage or jam the connecting cables, affecting the structural reliability of the sliding window assembly. Summary of the Invention

[0003] Therefore, it is necessary to provide a sliding window assembly and a vehicle to address the problem that the movement of sliding glass relative to fixed glass can easily lead to damage or jamming of the connecting wires, affecting the structural reliability of the sliding window assembly.

[0004] A sliding window component, comprising:

[0005] The first base has a window;

[0006] The second substrate is provided with the first heating wire;

[0007] Guide rod, disposed on the first base;

[0008] A driving block is connected to the second base and disposed on the guide rod. The driving block can move along the guide rod to drive the second base to move relative to the first base, so that the second base can block or expose the window.

[0009] A first telescopic member, one end of which is connected to the drive block, and the other end which is fixed relative to the first base, wherein at least a portion of the first telescopic member is telescopic in the extension direction of the guide rod; and,

[0010] The connecting wire is electrically connected to the first heating wire and is at least partially disposed on the first telescopic member.

[0011] In one embodiment, the first telescopic member is sleeved on the guide rod along the outer periphery of the guide rod.

[0012] In one embodiment, the shortest distance between the first telescopic member and the guide rod at the outer periphery of the guide rod is greater than or equal to 1.5 mm.

[0013] In one embodiment, at least a portion of the connecting line disposed on the first telescopic member is embedded within the first telescopic member and is wrapped by the first telescopic member.

[0014] In one embodiment, at least a portion of the first telescopic member is a bellows, the first telescopic member having a valley bottom near the guide rod and a valley top away from the guide rod in a radial direction, the connecting line passing at least through the valley bottom and valley top of the first telescopic member.

[0015] In one embodiment, the portion of the connecting line on the first telescopic member is spirally wound around the first telescopic member.

[0016] In one embodiment, at least a portion of the outer peripheral surface of the guide rod is threaded, the inner sidewall of the drive block is threadedly engaged with the guide rod, and the sliding window assembly further includes a drive element disposed on the first base and having its output end connected to the guide rod. The drive element is used to drive the guide rod to rotate relative to the first base.

[0017] In one embodiment, the sliding window assembly further includes a rotating seat fixedly disposed on the first base, one end of the guide rod away from the drive element being rotatably inserted into the rotating seat, and the first telescopic member being telescopic at least in the portion between the rotating seat and the drive block.

[0018] In one embodiment, the sliding window assembly further includes a second telescopic member located on the side of the drive block away from the first telescopic member. One end of the second telescopic member is connected to the drive block, and the other end is fixed relative to the first base. The second telescopic member is sleeved on the guide rod along the outer periphery of the guide rod, and at least a portion of the second telescopic member is telescopic in the extension direction of the guide rod.

[0019] In one embodiment, a second heating wire is provided on the first substrate, with a portion of the connecting wire extending from one end of the first telescopic member near the driving block and electrically connected to the first heating wire, and another portion extending from one end of the first telescopic member away from the driving block and electrically connected to the second heating wire.

[0020] In one embodiment, the second base is provided with a mating structure, the mating structure having a mating groove, the driving block being movably inserted into the mating groove, the second base having a first state of obscuring the window and a second state of exposing the window, in the first state, at least a portion of the second base is embedded in the window, and in the direction in which the second base moves from the first state to the second state, at least a portion of the mating groove is inclined toward the side closer to the first base.

[0021] In one embodiment, the sliding window assembly further includes a first guide rail, in which the guide rod and the first telescopic member are both disposed, and the first guide rail is provided with a first guide groove, the extension direction of the first guide groove being parallel to the guide rod, and the drive block passing through the first guide groove.

[0022] In one embodiment, the first guide rail is further provided with a second guide groove, and the second base is further provided with a first guide structure movably disposed in the second guide groove. The second base has a first state of obscuring the window and a second state of exposing the window. In the direction in which the second base moves from the second state to the first state, a portion of the second guide groove is inclined toward the side where the first base is located.

[0023] A vehicle includes a vehicle body and a sliding window assembly as described in any of the above embodiments, the sliding window assembly being disposed on the vehicle body.

[0024] In the aforementioned sliding window assembly, when the drive block moves along the guide rod to cause the second base to move relative to the first base, thus obscuring or revealing the window, the first telescopic member can extend or retract in the extension direction of the guide rod as the drive block moves along the guide rod, adapting to the movement of the drive block. The connecting wires provided on the first telescopic member can converge or expand as the first telescopic member extends or retracts, adapting to the movement of the drive block and the second base. This maintains the stability of the electrical connection between the connecting wires and the first heating wires on the second base during the movement of the second base relative to the first base. Simultaneously, the first telescopic member provides good protection and support for the connecting wires, constraining their movement trajectory, reducing vibration, and lowering the risk of damage or jamming due to the movement of the second base. This improves the structural reliability and performance stability of the sliding window assembly. Furthermore, the aforementioned sliding window assembly integrates the connecting wires and their constraint structure (i.e., the first telescopic member) with the drive block and guide rod, improving the structural compactness of the sliding window assembly, reducing its space requirements, and facilitating its installation and application in vehicles.

Detailed Implementation

[0046] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0047] Traditional rear windshields consisting of sliding window assemblies require heating wires on the sliding glass to be powered via connecting cables. When the sliding glass slides relative to the fixed glass, the connecting cables typically swing, making them prone to wear or jamming. To reduce the risk of damage or jamming, additional limiting mechanisms are usually needed to restrict the cable's movement, resulting in a complex structure and large space requirements. Furthermore, under conditions of vehicle vibration, the shaking amplitude of the heating cables increases, further increasing the probability of damage or jamming, thus affecting the structural and performance reliability of the sliding window assembly.

[0048] To address the aforementioned problems, this application provides a sliding window assembly and a vehicle.

[0049] refer to Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a schematic diagram of the sliding window assembly in some embodiments of this application when the second base 12 is in the second state. Figure 2 and 3 This is a schematic diagram of the sliding window assembly at different angles when the second base 12 is in the first state in some embodiments of this application.

[0050] The sliding window assembly provided in this application can be applied to any suitable vehicle, such as pickup trucks and cars. The vehicle also includes the vehicle body, and the sliding window assembly is installed on the vehicle body, for example, on the body sheet metal. The sliding window assembly includes, but is not limited to, the rear windshield of the vehicle, and can be specifically configured according to requirements.

[0051] In some embodiments, the sliding window assembly includes a first base 11 and a second base 12. The first base 11 is the fixed part of the sliding window assembly. At least a portion of the first base 11 can be glass. The first base 11 can be a single piece of glass, or it can include glass and a frame or edging structure surrounding the glass. The first base 11 is used to be mounted on the vehicle body, and a portion of the first base 11 is hollowed out to form a window 111. The second base 12 is movably disposed on the first base 11. The second base 12 is the sliding part of the sliding window assembly. At least a portion of the second base 12 can be glass. The second base 12 can be a single piece of glass. In this embodiment, the second base 12 includes a glass portion 121 and a frame portion 122 surrounding the glass as an example. The second base 12 can move relative to the first base 11 until at least a portion of the window 111 is exposed, or it can move relative to the first base 11 to cover the window 111, thereby meeting different usage needs of the vehicle. In this application, the state in which the second substrate 12 completely covers the window 111 is referred to as the first state of the second substrate 12, and the state in which the second substrate 12 exposes the window 111 and the exposed area reaches its maximum is referred to as the second state of the second substrate 12.

[0052] In some embodiments, a first heating wire (not shown) is provided on at least a portion of the second substrate 12. For example, a first heating wire is provided on the glass portion 121 of the second substrate 12, and a second heating wire (not shown) is provided on at least a portion of the first substrate 11. The first heating wire and the second heating wire can both be metal wires or the like. The first heating wire and the second heating wire can heat the first substrate 11 and the second substrate 12 to achieve a defrosting effect and improve the user experience of the sliding window assembly.

[0053] Furthermore, combined Figure 4, Figure 5 and Figure 6 As shown, in some embodiments, the sliding window assembly further includes a guide rod 13, a drive block 14, a first telescopic member 15, and a connecting line 16. The guide rod 13 is disposed on a first base 11, and the drive block 14 is connected to a second base 12, for example, fixedly connected to the frame portion 122 of the second base 12. The drive block 14 is movably disposed on the guide rod 13 and can move along the guide rod 13 to drive the second base 12 to move relative to the first base 11, so that the second base 12 switches between a first state and a second state. One end of the first telescopic member 15 is connected to the drive block 14, for example, fixedly connected to the drive block 14, and the other end is fixed relative to the first base 11. At least a portion of the first telescopic member 15 is telescopic in the extension direction of the guide rod 13. The connecting line 16 is electrically connected to a first heating wire for supplying power to the first heating wire. At least a portion of the connecting line 16 is disposed on the first telescopic member 15, and the dimension of the connecting line 16 in the extension direction of the guide rod 13 can change with the extension and retraction of the first telescopic member 15.

[0054] It is understood that the drive block 14 can move along the guide rod 13 in the extension direction of the guide rod 13. The extension direction of the guide rod 13 can be parallel to the direction in which the second base 12 moves from the second state to the first state relative to the first base 11, and also parallel to the direction in which the second base 12 moves from the first state to the second state relative to the first base 11. When the drive block 14 moves along the guide rod 13, it can drive the second base 12 to switch between the first state and the second state. At the same time, it can also drive the first telescopic member 15, which is fixedly connected to the drive block 14, to move, thereby causing at least a portion of the first telescopic member 15 to extend or retract in the extension direction of the guide rod 13. This, in turn, causes at least a portion of the connecting line 16 to converge or expand in the extension direction of the guide rod 13, so that the position of the end of the connecting line 16 connected to the first heating line can change with the position of the second base 12 relative to the first base 11.

[0055] Therefore, in the aforementioned sliding window assembly, the first telescopic member 15 can extend and retract to adapt to the movement of the second base 12. The connecting line 16 provided on the first telescopic member 15 can converge or expand to adapt to the movement of the second base 12. This helps maintain the electrical connection stability between the connecting line 16 and the first heating wire on the second base 12 during the movement of the second base 12 relative to the first base 11. At the same time, the first telescopic member 15 can provide good protection and support for the connecting line 16, constrain the movement trajectory of the connecting line 16, reduce the vibration of the connecting line 16, and reduce the risk of the connecting line 16 being damaged or stuck between the first base 11 and the second base 12 due to the movement of the second base 12. This helps improve the structural reliability and performance stability of the sliding window assembly. In addition, the aforementioned sliding window assembly can also integrate the connecting line 16 and the constraint structure of the connecting line 16 (i.e., the first telescopic member 15) with the drive block 14 and the guide rod 13, which helps improve the structural compactness of the sliding window assembly, reduce the space occupied by the sliding window assembly, and facilitate the installation and application of the sliding window assembly in vehicles.

[0056] refer to Figure 7 and Figure 8 As shown, in some embodiments, at least a portion of the outer peripheral surface of the guide rod 13 is threaded, and the guide rod 13 can be a lead screw. The drive block 14 is sleeved on the guide rod 13, and at least a portion of the inner sidewall of the drive block 14 is threaded, with the inner sidewall of the drive block 14 threadedly engaging with the guide rod 13. The sliding window assembly also includes a drive element 17, which is disposed on the first base 11 and has its output end connected to the guide rod 13. The drive element 17 is used to drive the guide rod 13 to rotate relative to the first base 11. The drive element 17 includes, but is not limited to, any suitable element capable of rotational output, such as a motor or electric motor. When the output end of the motor drives the guide rod 13 to rotate relative to the first base 11, the threaded engagement between the guide rod 13 and the drive block 14 converts the rotational motion of the guide rod 13 into linear motion of the drive block 14 along the guide rod 13, thereby driving the second base 12 to move relative to the first base 11.

[0057] Using a lead screw to drive the second base 12 simplifies the design of the drive mechanism for the sliding window assembly, reducing costs and space requirements. Of course, the drive mechanism for the sliding window assembly can also be implemented using any other suitable method, such as a linear motor and slide rail, as long as it can drive the drive block 14 to move the second base 12 along the guide rod 13.

[0058] In some embodiments, the first telescopic member 15 is a hollow structure, and is sleeved on the guide rod 13 along the outer periphery of the guide rod 13. Thus, while limiting the connection line 16, the first telescopic member 15 also provides dustproof protection for the portion of the guide rod 13 enclosed by the first telescopic member 15, preventing dust accumulation on the guide rod 13 and thus blocking the movement of the drive block 14 along the guide rod 13. Furthermore, the guide rod 13 itself also provides a limiting function for the first telescopic member 15, preventing it from swinging significantly radially or even falling off, which helps improve the structural reliability of the sliding window assembly.

[0059] In some embodiments, the first telescopic member 15 is spaced apart from the guide rod 13, and the maximum distance between the first telescopic member 15 and the guide rod 13 at the outer periphery of the guide rod 13 is greater than or equal to 1.5 mm. This reduces the risk of interference between the first telescopic member 15 and the guide rod 13 during the movement of the drive block 14, and also reduces the risk of wear on the first telescopic member 15 or the connecting line 16 on the first telescopic member 15 by the guide rod 13. Of course, the distance between the first telescopic member 15 and the guide rod 13 can be understood as the initial distance between the first telescopic member 15 and the guide rod 13 after the first telescopic member 15 is fitted onto the guide rod 13. Ideally, the distance between the first telescopic member 15 and the guide rod 13 at all points along the circumference of the guide rod 13 can be approximately equal, and all greater than or equal to 1.5 mm. During the use of the vehicle, the first telescopic member 15 may swing relative to the guide rod 13 in the radial direction, causing changes in the distance between the first telescopic member 15 and the guide rod 13.

[0060] In some embodiments, at least a portion of the connecting wire 16 disposed on the first telescopic member 15 is embedded within the first telescopic member 15 and is wrapped by the first telescopic member 15. Thus, the first telescopic member 15 can provide effective protection for the connecting wire 16. During the process of the connecting wire 16 converging or expanding with the extension and retraction of the first telescopic member 15, the connecting wire 16 is less likely to detach from the first telescopic member 15, nor is it easily damaged by wear or breakage, which helps improve the reliability of the structure and electrical connection performance.

[0061] The specific configuration of the first telescopic member 15 is not limited, as long as it can provide space for the connecting line 16 to be installed and can extend and retract with the movement of the drive block 14. In some embodiments, the first telescopic member 15 is a bellows. The bellows can provide sufficient deformation space, and the complex surface shape of the bellows makes it easier to install the connecting line 16 on the first telescopic member 15.

[0062] Furthermore, in some embodiments, the first telescopic member 15 has a valley bottom 151 near the guide rod 13 and a valley top 152 away from the guide rod 13 in the radial direction, and the connecting line 16 passes at least through the valley top 152 and the valley top 152 of the guide rod 13. For example, combined with Figure 8 and Figure 9 As shown, in some embodiments, the portion of the connecting wire 16 on the first telescopic member 15 is spirally wound around the first telescopic member 15. The connecting wire 16 may include a first line 161 and a second line 162, one of which corresponds to the positive connection line and the other to the negative connection line. The first line 161 is spirally wound and passes through the valley bottom 151 of the first telescopic member 15. The second line 162 is spirally wound and its portion on the first telescopic member 15 is located outside the first line 161, passing through the valley top 152 of the first telescopic member 15. This arrangement allows for a reasonable layout of the connecting wire 16 on the first telescopic member 15, making it less likely for the positive and negative connection lines to interfere with each other and short-circuit. It also makes full use of the shape of the first telescopic member 15 for wiring, reducing the risk of damage to the connecting wire 16 during movement.

[0063] The process of embedding the connecting wire 16 within the first telescopic member 15 is not limited; any applicable process, such as co-extrusion molding or compression molding, can be used to prepare the connecting wire 16 and the first telescopic member 15 as a whole. For example, when using co-extrusion molding, the first telescopic member 15 can be a plastic corrugated tube. The plastic raw material can be extruded into a corrugated tube blank using an extruder, and the connecting wire 16 can be fed into the preset valley bottom 151 and valley top 152 cavities through the guide channel of the die. Then, it is shaped by a cooling water tank, so that the surfaces of the first telescopic member 15 and the connecting wire 16 form a covering force, thereby obtaining the connecting wire 16 and the first telescopic member 15 as a whole. When using compression molding, any grooves of valley bottom 151 and valley top 152 can be pressed out during the molding process using a customized die, and then the connecting wire 16 is placed into the grooves and fixed by secondary compression molding.

[0064] Of course, the connecting line 16 is not limited to being embedded in the first telescopic member 15. The connecting line 16 can also be connected to the outer or inner surface of the first telescopic member 15 by any applicable method such as adhesive, so as to simplify the manufacturing process of the first telescopic member 15 and the connecting line 16 and reduce the manufacturing cost. As long as the connecting line 16 can be firmly fixed on the first telescopic member 15 and can be gathered or unfolded with the movement of the drive block 14, it is acceptable.

[0065] refer to Figure 5 , Figure 6 and Figure 7As shown, in some embodiments, the sliding window assembly further includes a rotating seat 18 fixedly disposed on the first base 11. The end of the guide rod 13 away from the driving element 17 is rotatably inserted into the rotating seat 18. The first telescopic member 15 is telescopic at least in the portion between the rotating seat 18 and the driving block 14. A bearing may be provided inside the rotating seat 18 to rotatably engage with the guide rod 13, providing limiting and support for the guide rod 13 and improving the stability and reliability of the rotation of the guide rod 13 relative to the first base 11.

[0066] The method by which the end of the first telescopic member 15 away from the drive block 14 is fixed relative to the first base 11 is not limited. For example, it can be fixedly connected to the rotating seat 18 or the first base 11 by any applicable method such as adhesive.

[0067] In some embodiments, the sliding window assembly further includes a housing 19, a drive element 17 disposed within the housing 19, and one end of a guide rod 13 passing through the housing 19 and connected to the output end of the drive element 17 within the housing 19. A bearing may also be disposed within the housing 19 at a location away from the drive element 17, rotating in conjunction with the guide rod 13. This configuration allows the housing 19 to provide protection and shielding for the ends of the drive element 17 and the guide rod 13, improving the appearance integrity and structural reliability of the sliding window assembly, while also enhancing the stability and reliability of the guide rod 13's rotation relative to the first base 11.

[0068] refer to Figure 5 and Figure 6 As shown, in some embodiments, a second heating wire is provided on the first substrate 11. A connecting wire 16 extends from one end of the first telescopic member 15 near the driving block 14 and is electrically connected to the first heating wire, while the other end extends from the end of the first telescopic member 15 away from the driving block 14 and is electrically connected to the second heating wire. This allows for full utilization of the first telescopic member 15 to protect and route the connecting wire 16, shortening the length of the connecting wire 16 outside the first telescopic member 15. Simultaneously, the extension of the connecting wire 16 can be adapted to the placement positions of the first and second heating wires, effectively connecting them electrically. In some embodiments, the connecting wire 16 connects the first and second heating wires in parallel, simplifying the wiring of the sliding window assembly, reducing manufacturing costs, and improving the reliability of the electrical connection performance while simultaneously supplying power to the first and second heating wires through the connecting wire 16.

[0069] In some embodiments, the sliding window assembly further includes a wiring structure 21, which is disposed on the first base 11 and located at the end of the first telescopic member 15 away from the drive block 14, for example, near the rotating seat 18. The end of the connecting wire 16 away from the drive block 14 extends from the first telescopic member 15 and is at least partially disposed within the wiring structure 21, and is electrically connected to the second heating wire within the wiring structure 21, or extends from the wiring structure 21 to connect to the second heating wire. The wiring structure 21 provides limiting and protection for the portion of the connecting wire 16 used for electrical connection with the second heating wire, constrains the direction of the connecting wire 16, reduces the risk of wear or even breakage of the connecting wire 16 due to vibration caused by vehicle bumps, and improves the reliability of the electrical connection performance of the sliding window assembly.

[0070] Please see again. Figure 1 and Figure 3 In some embodiments, when the second base 12 is partially or fully positioned within the window 111 of the first base 11, the second base 12 is located on one side of the first base 11 in the thickness direction to avoid interference between the first base 11 and the second base 12, which would affect the movement of the second base 12 relative to the first base 11. When the second base 12 moves relative to the first base 11 to a first state, at least a portion of the second base 12 is embedded within the window 111 of the first base 11, and at least a portion of the thicknesses of the second base 12 and the first base 11 overlap. Thus, the second base 12 can effectively seal the window 111 in the first state, enabling the sliding window assembly to have waterproof and dustproof effects. That is, during the process of the second base 12 moving relative to the first base 11 to switch from the second state to the first state, there is a relative displacement between the second base 12 and the first base 11 in the thickness direction, and the second base 12 moves relative to the first base 11 in the thickness direction towards the first base 11.

[0071] refer to Figure 10 and Figure 11As shown, in some embodiments, a mating structure 123 is provided on the second base 12. The mating structure 123 may protrude from the frame portion 122 of the second base 12. The mating structure 123 has a mating groove 1231, and the driving block 14 is movably inserted into the mating groove 1231. In the direction in which the second base 12 moves from the first state to the second state, at least a portion of the mating groove 1231 is inclined toward the side closer to the first base 11. The mating groove 1231 may be an inclined groove partially inclined toward the side closer to the first base 11, or it may be an arc-shaped groove. With this configuration, during the transition of the second base 12 from the second state to the first state, the driving block 14 can slide within the mating groove 1231, thereby generating a displacement between the second base 12 and the driving block 14 along the thickness direction of the first base 11. For example, when the driving block 14 slides within the arcuate groove and the inclined groove of the mating groove 1231, the second base 12 can generate a displacement relative to the driving block 14 toward the first base 11, allowing the second base 12 to be embedded within the window 111 and switch to the first state.

[0072] Combination Figure 12 As shown, in some embodiments, the sliding window assembly further includes a first guide rail 22, with the guide rod 13 and the first telescopic member 15 both disposed within the first guide rail 22. The first guide rail 22 provides protection and shielding for the guide rod 13 and the first telescopic member 15, improving the aesthetics and structural reliability of the sliding window assembly. The first guide rail 22 is provided with a first guide groove 221, at least a portion of which extends parallel to the guide rod 13. A drive block 14 passes through the first guide groove 221, with one end slidably disposed within a mating groove 1231 and the other end threadedly engaged with the guide rod 13. When the drive block 14 moves along the guide rod 13, it also moves along the first guide groove 221. The first guide groove 221 provides guidance for the movement of the drive block 14 along the guide rod 13, improving the reliability of the movement of the second base 12 relative to the first base 11.

[0073] refer to Figure 10 , Figure 12 and Figure 13 As shown, in some embodiments, the first guide rail 22 is further provided with a second guide groove 222, and the frame portion 122 of the second base 12 is further provided with a first guide structure 124 movably disposed within the second guide groove 222. At least a portion of the extension direction of the second guide groove 222 may be parallel to the extension direction of the guide rod 13. During the movement of the second base 12 relative to the first base 11, the first guide structure 124 also slides along the second guide groove 222. The second guide groove 222 can provide a limiting effect on the movement of the first guide structure 124, which is also beneficial to improving the stability and reliability of the movement of the second base 12 relative to the first base 11.

[0074] In some embodiments, the first guide groove 221 and the second guide groove 222 are not connected to each other and are spaced apart in the thickness direction of the first base 11. This arrangement ensures that the sliding of the drive block 14 along the first guide groove 221 and the sliding of the first guide structure 124 along the second guide groove 222 do not interfere with each other, which helps to improve the structural reliability of the sliding window assembly.

[0075] Furthermore, in some embodiments, in the direction in which the second base 12 moves from the second state to the first state, a portion of the second guide groove 222 is inclined toward the side where the first base 11 is located. For example, the end of the second guide groove 222 away from the rotating seat 18 is inclined toward the side where the first base 11 is located, and the end of the second guide groove 222 can be a slanted groove or an arc-shaped groove. With this configuration, when the second base 12 slides relative to the first base 11 to a position close to or corresponding to the first state, the first guide structure 124 can slide along the slanted or arc-shaped groove portion of the second guide groove 222 and generate a displacement relative to the first guide rail 22 along the thickness direction of the first base 11. This causes the first guide structure 124 and the second base 12 as a whole to move closer to the first base 11 along the thickness direction of the first base 11, so that at least a portion of the second base 12 can be smoothly embedded into the window 111, improving the sealing performance between the first base 11 and the second base 12 in the first state.

[0076] exist Figure 12 and Figure 13 In the embodiment shown, there are two first guide structures 124. The two first guide structures 124 are arranged at intervals in the extension direction of the guide rod 13, for example, at both ends of the second base 12 near the edge of the first guide rail 22. The first guide rail 22 is provided with two spaced second guide grooves 222. The two first guide structures 124 are slidably arranged in the two second guide grooves 222 in a one-to-one correspondence, so as to improve the stability and reliability of the movement of the second base 12 relative to the first base 11.

[0077] refer to Figure 5 , Figure 10 and Figure 14As shown, in some embodiments, the sliding window assembly further includes a second guide rail 23. The first guide rail 22 and the second guide rail 23 can be respectively disposed on opposite sides of the second base 12 in the width direction of the first base 11. A second guide structure 125 is also provided on the frame portion 122 of the second base 12. The first guide structure 124 and the second guide structure 125 can be respectively disposed on opposite edges of the frame portion 122. A third guide groove 231 is provided on the second guide rail 23, and the second guide structure 125 is slidably disposed in the third guide groove 231. When the second base 12 moves relative to the first base 11, the second guide structure 125 also slides along the third guide groove 231. The first guide rail 22 and the second guide rail 23 on opposite sides of the second base 12 limit the movement of the second base 12 relative to the first base 11, which helps to improve the stability and reliability of the movement of the second base 12 relative to the first base 11.

[0078] Combination Figure 15 As shown, in some embodiments, in the direction in which the second base 12 moves from the second state to the first state, a portion (e.g., the end) of the second guide groove 222 is inclined toward the side where the first base 11 is located, so that the second guide structure 125 can be displaced relative to the second guide rail 23 in the thickness direction of the first base 11, allowing at least a portion of the second base 12 to be smoothly embedded in the window 111 to switch to the first state. Two second guide grooves 222 and two second guide structures 125 may also be provided to improve the stability and reliability of the sliding of the second base 12 relative to the first base 11. For details, refer to the configuration of the first guide structure 124, which will not be elaborated here.

[0079] In any of the above embodiments of the sliding window assembly, when the second base 12 is in the second state, the second base 12 is located on one side of the first base 11 in the thickness direction, the first telescopic member 15 is in a compressed state, and the connecting line 16 is in a converged state. When the driving element 17 drives the guide rod 13 to rotate relative to the first base 11, the driving block 14 drives the second base 12 to move relative to the first base 11 along the guide rod 13, the first guide structure 124 slides along the second guide groove 222, and the second guide structure 125 slides along the third guide groove 231. Under the drive of the driving block 14, the first telescopic member 15 is stretched, and the connecting line 16 unfolds, so that the part of the connecting line 16 electrically connected to the first heating wire moves with the movement of the second base 12. When the second base 12 moves relative to the first base 11 until the first guide structure 124 slides along the inclined or arcuate groove of the second guide groove 222, the second guide structure 125 slides along the arcuate or inclined groove of the third guide groove 231, and the driving block 14 slides in the arcuate or inclined groove portion of the mating groove 1231, the second base 12 moves towards the first base 11 in the thickness direction, such that at least a portion of the second base 12 is embedded in the window 111, and the second base 12 switches to the first state. The process of the second base 12 switching from the first state to the second state can be the reverse of the above process, which will not be elaborated here.

[0080] It should be noted that, in Figure 4 and Figure 5 In the embodiment shown, the first telescopic member 15 is disposed between the drive block 14 and the rotating seat 18, for reference. Figure 5 As shown, when the drive block 14 moves between the rotating seat 18 and the housing 19 to the position closest to the housing 19 (i.e., closest to the drive element 17), the extension length of the first telescopic member 15 reaches its maximum, and the coverage area of ​​the guide rod 13 reaches its maximum, which can effectively prevent dust from falling onto the guide rod 13 and reduce the risk of dust blocking the drive block 14 from moving along the guide rod 13. However, referring to Figure 4 As shown, when the drive block 14 moves toward the rotating seat 18 and away from the housing 19, the part of the guide rod 13 located between the drive block 14 and the housing 19 is not covered by the first telescopic member 15 and is exposed. The closer the drive block 14 is to the rotating seat 18 relative to the housing 19, the larger the area of ​​the exposed part of the guide rod 13 is.

[0081] To prevent dust from falling onto the exposed part of the guide rod 13 and obstructing the movement of the drive block 14 along the guide rod 13, refer to... Figure 16 and Figure 17In some embodiments, the sliding window assembly further includes a second telescopic member 24, which is located on the side of the drive block 14 away from the first telescopic member 15, with one end connected to the drive block 14 and the other end fixed relative to the first base 11. The second telescopic member 24 is sleeved on the guide rod 13 along the outer periphery of the guide rod 13, and at least a portion of the second telescopic member 24 is telescopic in the extending direction of the guide rod 13. When the sliding window assembly is provided with a drive element 17 and a housing 19, the second telescopic member 24 can be disposed between the drive block 14 and the housing 19. One end of the second telescopic member 24 can be fixedly connected to the drive block 14 by any applicable method such as adhesive, snap-fit, or sleeve, and the other end of the second telescopic member 24 can be fixedly connected to the housing 19 or the first base 11 by any applicable method such as adhesive, snap-fit, or sleeve.

[0082] refer to Figure 16 and Figure 17 As shown, it can be understood that when the drive block 14 is closest to the housing 19 relative to the rotating seat 18, the first telescopic member 15 has the longest extension length, while the second telescopic member 24 is compressed to the greatest extent. (Reference) Figure 18 and Figure 19 As shown, when the drive block 14 moves along the guide rod 13 in a direction away from the housing 19 and closer to the rotating seat 18, the extension length of the first telescopic member 15 gradually decreases, the distance between the drive block 14 and the housing 19 gradually increases, and the second telescopic member 24 gradually extends with the movement of the drive block 14, so that the coverage area of ​​the second telescopic member 24 on the guide rod 13 gradually increases. It can be seen that the second telescopic member 24, in conjunction with the first telescopic member 15, extends when the first telescopic member 15 retracts to cover the portion of the guide rod 13 not covered by the first telescopic member 15. Therefore, it can work together with the first telescopic member 15 to provide dust protection for the guide rod 13, preventing dust from accumulating on the guide rod 13 and obstructing the movement of the drive block 14 along the guide rod 13.

[0083] The specific structure, shape, size settings, and relative relationship with the guide rod 13 of the second telescopic member 24 can be obtained by referring to the settings of the first telescopic member 15. The difference between the second telescopic member 24 and the first telescopic member 15 is that the connecting line 16 may not be provided on the second telescopic member 24.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
