[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] Electric window openers are machines that use electricity to open and close window sashes. These electric window openers replace manual operation, providing great convenience to people's lives. However, existing electric window openers can only be connected to fixed window frames via a single type of connector (e.g., fasteners or brackets), making them unsuitable for window frames of different sizes and structures, resulting in poor adaptability and versatility. Furthermore, in existing electric window openers, the wiring harness typically passes through the outside, or through the inside without a barrier, or even if a barrier is present, it cannot independently define the guiding space. This reduces the aesthetics of the electric window opener, and the wiring harness is easily damaged by external influences. In addition, the wiring harness is prone to interference with internal components, hindering their operation, and the internal wiring harness is also susceptible to damage.

[0004] Therefore, improvements are needed to the existing electric window openers in order to at least partially solve the problems existing in the existing technology. Utility Model Content

[0038] Exemplary embodiments will now be described in full with reference to the accompanying drawings.

[0039] This document provides exemplary embodiments to make the present invention exhaustive and to convey its scope more fully to those skilled in the art. Numerous specific details, such as examples of specific components and devices, are set forth to provide a thorough understanding of various embodiments of the present invention, and these specific details should not be construed as limiting the scope of the present invention. It will be apparent to those skilled in the art that the exemplary embodiments may be implemented in many different forms, not limited to the specific details disclosed. In some exemplary embodiments, well-known processes, well-known device structures, and well-known techniques are not described in detail.

[0040] In a first aspect of this utility model, an electric window opener 1 is provided.

[0041] The following will combine Figures 1 to 16 The electric window opener 1 according to this utility model will be described in detail.

[0042] like Figure 1 and Figure 2 As shown, the electric window opener 1 according to this utility model includes: a housing 10, a motor assembly 20, a gear assembly 30 driven by the motor assembly 20, a sprocket assembly 40 driven by the gear assembly 30, and a chain member 50 driven by the sprocket assembly 40. The motor assembly 20, gear assembly 30, and sprocket assembly 40 are arranged within the housing 10. The chain member 50 is movable between an extended position and a retracted position in a direction perpendicular to the longitudinal direction of the electric window opener 1 (this perpendicularity can be completely perpendicular or approximately perpendicular) under the drive of the sprocket assembly 40.

[0043] In this invention, the direction parallel to the longitudinal direction of the electric window opener 1 is defined as the longitudinal direction, while the direction perpendicular to the longitudinal direction and perpendicular to the extension and retraction direction of the chain member 50 is defined as the front-back direction (this direction can also be understood as the lateral direction of the electric window opener 1).

[0044] like Figure 2 As shown, the housing 10 includes a first housing portion 11 (in Figure 2 In the middle, the first housing portion 11 is located on the front side and can therefore also be called the front housing portion) and the second housing portion 12 (in Figure 2 In this case, the second housing portion 12 is located at the rear and can therefore also be referred to as the rear housing portion. (For example...) Figure 1 and Figure 2 As shown, the housing 10 includes left-side surfaces located on both sides of the housing 10 along the longitudinal direction (in Figure 2 The middle is located on the left side of the housing 10 and the right side surface (in Figure 2 The front surface 110 located on both sides of the housing 10 along the front-rear direction is located on the right side of the housing 10. Figure 2The middle part is located on the front side of the housing 10, specifically on the front side of the first housing portion 11) and the rear surface 120 (in Figure 2 The middle part is located at the rear side of the housing 10, specifically at the rear side of the second housing portion 12), and the upper surfaces of the housing 10 on both sides along the telescoping direction of the chain member 50 (in Figure 2 The middle part is located on the upper side of the housing 10 and the lower surface (in Figure 2 (Located on the lower side of the housing 10).

[0045] like Figure 2 As shown, each of the first housing portion 11 and the second housing portion 12 has holes (not shown) at its four adjacent corner positions, such that the first housing portion 11 and the second housing portion 12 can be fastened together to form the housing 10 by inserting fasteners into the holes. Figure 2As shown, the upper surface of the housing 10 includes an opening 14 through which a portion of the chain member 50 can extend outside the housing 10 or retract into the housing 10. The motor assembly 20 includes a motor, and a worm gear (not shown) is fixed to the output shaft of the motor. The gear assembly 30 may include multiple gears and is driven by the output shaft of the motor, causing the multiple gears of the gear assembly 30 to rotate. The sprocket assembly 40 may include a coaxial input gear 41 and an output ratchet 42. The chain member 50 may include a plurality of chain units 51 and a chain head 52, each chain unit 51 being pivotally connected to its adjacent chain unit 51. The chain units 51 in the chain member 50 are adapted to engage with the output ratchet 42 in the sprocket assembly 40, thereby extending or retracting as the output ratchet 42 rotates. One end of the chain head 52 is pivotally connected via a connecting pin to the head chain unit (the chain unit closest to the chain head 52) among the plurality of chain units 51. The size of the chain head 52 is larger than the size of the opening 14 of the housing 10, such that when the chain member 50 is retracted and the chain head 52 abuts against the opening 14 of the housing 10, the chain head 52 prevents the chain member 50 from retracting further, thereby acting as a stop. The other end of the chain head 52 is connected to the window sash frame via a specific connection method (such as bolts, rivets, screws, welding, bonding, slots, etc.) to transmit the movement (extension or retraction) of the chain unit 51 to the window sash, enabling the window sash to open or close according to the user's needs. After being powered on, the motor of the motor assembly 20 drives the worm gear to rotate. The worm gear meshes with the input gear (worm) in the gear assembly 30, thereby sequentially driving each gear in the gear assembly 30 to rotate. The last gear in the gear assembly 30, i.e., the output gear, meshes with the input gear 41 of the sprocket assembly 40. The output ratchet 42 of the sprocket assembly 40 meshes with the chain unit 51 of the chain member 50, so that the chain member 50 can move between the extended position and the retracted position in a direction perpendicular to the longitudinal direction of the electric window opener 1 under the drive of the sprocket assembly 40, thereby realizing the conversion of the rotation of the motor of the motor assembly 20 into the linear motion of the chain member 50.

[0046] In the electric window opener 1 of this invention, the housing 10 is configured to be connected to the window frame via at least two types of connectors (e.g., fasteners, brackets, and mounting tabs). Compared to existing electric window openers that can only be connected to fixed window frames via a single type of connector (e.g., only fasteners or only brackets), the electric window opener 1 of this invention can be connected to window frames of different sizes and structures in different ways via different types of connectors, giving it the advantages of flexible installation, adaptability, and versatility.

[0047] In some embodiments, at least two types of connectors include at least two of fasteners (e.g., fastening bolts, fastening screws, rivets, pins, etc.), brackets, and mounting tabs, so that the electric window opener can be selectively installed to the window frame via one of the fasteners, brackets, and mounting tabs according to the size and structure of the window. This makes the installation method of the electric window opener 1 of this invention flexible and improves the adaptability and versatility of the electric window opener.

[0048] In some embodiments, the housing 10 is configured to be connected to the window frame 2 of the window via fasteners. The housing 10 is provided with a first mounting interface 100 for receiving fasteners. The first mounting interface 100 may be located on at least one of the front surface 110, rear surface 120, left side surface, right side surface, upper surface, and lower surface of the housing 10. The first mounting interface 100 may be located at any suitable location on the front surface 110 and / or rear surface 120 of the housing 10 and extend through the front surface 110 and / or rear surface 120 of the housing; the first mounting interface 100 may also be located at any suitable location on the left side surface and / or right side surface of the housing 10 and extend through the left side surface and / or right side surface of the housing 10, or located at any suitable location on the upper surface and / or lower surface of the housing 10 and extend through the upper surface and / or lower surface of the housing 10. By providing a first mounting interface 100 on the housing 10 for receiving fasteners, the fasteners pass through the first mounting interface 100 of the housing 10 and are fastened to the window frame 2, thereby installing the housing 10 to the window frame 2, and subsequently installing the electric window opener 1 to the window frame 2. Figure 3 , Figure 5 and Figure 7 As shown, each of the front surface 110 and rear surface 120 of the housing 10 is provided with eight first mounting interfaces 100, and the eight first mounting interfaces 100 in the front surface 110 or rear surface 120 are distributed at different locations on the surface. The user can select one or more of the first mounting interfaces 100 as needed to install the housing 10 to the window frame 2. However, it is conceivable that any suitable number of first mounting interfaces 100 can be provided, and these first mounting interfaces 100 can be provided in one or more of the front surface 110, rear surface 120, left side surface, right side surface, upper surface and lower surface of the housing 10.

[0049] Figures 5 to 8 and Figure 11 Several exemplary embodiments of the housing 10 being mounted to the window frame 2 of the window by fasteners are shown. Figure 5 and Figure 6These are schematic front and right views showing the electric window opener 1 according to the present invention being mounted from the outside of the window frame 2 to the window frame 2 by fasteners in such a manner that the front surface 110 is away from the window frame 2. Figure 7 and Figure 8 These are schematic front and right views showing the electric window opener 1 according to the present invention being mounted from the outside of the window frame 2 to the window frame 2 by fasteners in such a manner that the rear surface 120 is away from the window frame 2. Figure 11 This is a schematic right view showing the electric window opener 1 according to the present invention installed inside the window frame 2 by fasteners.

[0050] like Figures 5 to 8 and Figure 11 As shown, a first mounting interface 100 for receiving fasteners can be provided in the front surface 110 and rear surface 120 of the housing 10, and the first mounting interface 100 is provided at corresponding positions in the front surface 110 and rear surface 120, so that the fastener passes through the corresponding first mounting interface 100 of the front surface 110 and rear surface 120 of the housing 10 and is fastened to the window frame 2, thereby installing the housing 10 to the window frame 2.

[0051] For example, such as Figure 5 and Figure 6 As shown, the electric window opener 1 is installed into the window frame 2 by first inserting a fastener through the first mounting interface 100 in the front surface 110 of the housing 10, then through the corresponding first mounting interface 100 in the rear surface 120 of the housing 10, and finally into the window frame 2. This allows the electric window opener 1 to be installed with the front surface 110 away from the window frame 2 (i.e., the fastener is inserted from the front surface 110 through the rear surface 120 and into the window frame 2, with the front surface 110 away from the window frame 2 and the rear surface 120 abutting against the window frame 2), thus achieving frontal installation of the electric window opener 1 (installation with the front surface 110 facing the user). At this time, from... Figure 6 It can be seen that the chain component 50 is located slightly to the right of the electric window opener 1 (i.e., Figure 6 (slightly to the right of the middle).

[0052] For example, such as Figure 7 and Figure 8As shown, the electric window opener 1 is installed into the window frame 2 by first inserting a fastener into the first mounting interface 100 passing through the rear surface 120 of the housing 10, then inserting it into the corresponding first mounting interface 100 passing through the front surface 110 of the housing 10, and finally inserting it into the window frame 2. This allows the electric window opener 1 to be installed with the rear surface 120 away from the window frame 2 (i.e., the fastener is inserted from the rear surface 120 through the front surface 110 and into the window frame 2, with the rear surface 120 away from the window frame 2 and the front surface 110 abutting against the window frame 2), thus achieving reverse installation of the electric window opener 1 (installation with the rear surface 120 facing the user). At this time, from... Figure 8 It can be seen that the chain component 50 is located slightly to the left of the electric window opener 1 (i.e., Figure 8 (slightly to the left of the middle).

[0053] For example, such as Figure 11 As shown, the electric window opener 1 can be installed inside the window frame 2 using fasteners. A support member 2a for supporting the electric window opener 1 can be provided inside the window frame 2. The window frame 2 has an opening through which the electric window opener 1 can be placed on the support member 2a inside the window frame 2. Then, a fastener is inserted through one side of the outer surface of the window frame 2, then through one side of the support member 2a, and then sequentially through the corresponding first mounting interfaces 100 in the rear surface 120 and front surface 110 of the housing 10 (or sequentially through the corresponding first mounting interfaces 100 in the front surface 110 and rear surface 120 of the housing 10) and tightened, thereby installing the electric window opener 1 inside the window frame 2. Alternatively, the fastener can further pass through the other side of the support member 2a and through the other side of the outer surface of the window frame 2.

[0054] However, it is conceivable that the first mounting interface 100 for receiving fasteners may be provided only in the front surface 110 of the housing 10 or only in the rear surface 120 of the housing 10, such that the fasteners pass through the corresponding first mounting interface 100 in the front surface 110 or rear surface 120 of the housing 10 and are fastened to the window frame 2, thereby mounting the housing 10 to the window frame 2. It is also conceivable that the first mounting interface 100 for receiving fasteners may also be additionally or alternatively provided in at least one of the left side surface, right side surface, upper surface, and lower surface of the housing 10.

[0055] In some embodiments, the housing 10 is configured to be connected to the window frame 2 of the window via a bracket. The housing 10 is provided with a second mounting interface 200 for receiving the connecting portion or fastener of the bracket. The second mounting interface 200 may be located on at least one of the front surface 110, rear surface 120, left side surface, right side surface, upper surface, and lower surface of the housing 10. The second mounting interface 200 may be located at any suitable location on the front surface 110 and / or rear surface 120 of the housing 10 and extend through the front surface 110 and / or rear surface 120 of the housing; the second mounting interface 200 may also be located at any suitable location on the left side surface and / or right side surface of the housing 10 and extend through the left side surface and / or right side surface of the housing 10, or located at any suitable location on the upper surface and / or lower surface of the housing 10 and extend through the upper surface and / or lower surface of the housing 10. By providing a second mounting interface 200 on the housing 10 for receiving a connecting portion or fastener of the bracket, the housing 10 is mounted to the window frame 2 via a bracket by receiving the connecting portion or fastener of the bracket into the second mounting interface 200. Figure 4 , Figure 6 , Figure 8 and Figure 10 As shown, four second mounting interfaces 200 are provided on the right side surface of the housing 10, and correspondingly, four second mounting interfaces 200 are also provided on the left side surface of the housing 10. The four second mounting interfaces 200 on the right or left side surface are distributed at different locations on that surface. The user can select one or more of the second mounting interfaces 200 as needed to install the housing 10 to the window frame 2. However, it is conceivable that any suitable number of second mounting interfaces 200 can be provided, and these second mounting interfaces 200 can be provided on one or more of the front surface 110, rear surface 120, left side surface, right side surface, upper surface, and lower surface of the housing 10.

[0056] Figure 9 and Figure 10 These are schematic front and right views showing the electric window opener 1 according to the present invention mounted from the outside of the window frame 2 to the window frame 2 via a bracket.

[0057] like Figure 9 and Figure 10As shown, the bracket includes two bracket units 3. Each bracket unit 3 includes a support arm 31, a mounting plate 32 for mounting the bracket unit 3 to the window frame 2, and a fastener 33 for fixing the support arm 31 to the housing 10. The left and right surfaces of the housing 10 are each provided with a second mounting interface 200 for receiving the fastener 33 of the bracket. Each bracket unit 3 is fixed to the left / right surface of the housing 10 by inserting the fastener 33 through a hole in the support arm 31 and into the second mounting interface 200 of the housing 10. Then, the mounting plate 32 of each bracket unit 3 is installed to the window frame 2 by fastening or adhesive. This allows the housing 10 to be mounted to the window frame 2 via the bracket. That is, the electric window opener 1 can be mounted to the window frame 2 from the outside of the window frame 2 via the bracket through the left and right surfaces of the housing 10.

[0058] It is conceivable that, in embodiments not shown in this utility model, the bracket can have different structures. For example, the bracket may include two bracket units, each bracket unit including a support arm with a connecting portion for connection to the housing 10 (this connecting portion may be the free end of the support arm). Each bracket unit can be fixed to the left / right surface of the housing 10 by inserting the connecting portion of each bracket unit into the second mounting interface 200 of the housing 10 (this connecting portion may be interference-fitted with the second mounting interface 200). Then, each bracket unit can be installed to the window frame 2 by fastening or bonding. This allows the housing 10 to be installed to the window frame 2 via the bracket. That is, the electric window opener 1 can be installed to the window frame 2 from the outside of the window frame 2 via the bracket through the left and right surfaces of the housing 10.

[0059] Alternatively, the second mounting interface 200 for receiving the bracket connection or fastener may be provided only in the front surface 110 or only in the rear surface 120 of the housing 10, allowing the bracket to be mounted to the front surface 110 or rear surface 120 of the housing 10, thereby mounting the housing 10 to the window frame 2. That is, the electric window opener 1 can be mounted to the window frame 2 from the outside of the window frame 2 via the bracket through the front surface 110 or rear surface 120 of the housing 10. It is also conceivable that the second mounting interface 200 for receiving the bracket connection or fastener may be additionally or alternatively provided in the upper and / or lower surface of the housing 10. Thus, the electric window opener 1 can be mounted to the window frame 2 from the outside of the window frame 2 via the bracket through the upper and / or lower surface of the housing 10.

[0060] Alternatively, in embodiments not shown in this utility model, the bracket may include only one bracket unit, which can be connected to the housing 10 and the window frame 2 in the installation manner described above, so that the electric window opener 1 is installed to the window frame 2 via the bracket.

[0061] In some embodiments, at least two types of connectors include fasteners and brackets. The housing 10 is provided with a first mounting interface 100 for receiving fasteners and a second mounting interface 200 for receiving the connecting part or fixing member of the bracket. This allows the electric window opener 1 to be selectively connected to the window frame 2 of the window via fasteners and brackets. Thus, the electric window opener 1 can select different connectors (fasteners or brackets) to be installed on the window frame according to actual needs, making the installation method of the electric window opener 1 flexible and improving the adaptability and versatility of the product.

[0062] In some embodiments, the first mounting interface 100 for receiving fasteners and the second mounting interface 200 for receiving bracket connections or fasteners can be located at different positions on the same surface of the housing 10, including the front, rear, left, right, upper, and lower surfaces. This simplifies the manufacturing process of the housing 10 by requiring only one opening on a single surface, and allows the electric window opener 1 to be installed onto the window frame 2 of the window through different parts of that surface, selecting different connectors (fasteners or brackets) as needed. This makes the electric window opener 1 flexible in installation, adaptable, and versatile.

[0063] In some embodiments, the first mounting interface 100 for receiving fasteners and the second mounting interface 200 for receiving the connecting portion or fixing member of the bracket can be respectively provided on different surfaces of the front, rear, left, right, upper, and lower surfaces of the housing 10. For example, Figure 5 and Figure 7 As shown, the first mounting interface 100 for receiving fasteners may be located in the front surface 110 and / or rear surface 120 of the housing 10; while as Figure 10 As shown, the second mounting interface 200 for receiving the bracket connection or fastener can be located on the left and right surfaces of the housing 10. Therefore, the electric window opener 1 can be installed on the window frame 2 through different surfaces according to the installation space of window frames of different sizes and structures, making the installation method of the electric window opener 1 flexible, adaptable, and highly versatile.

[0064] According to this utility model, the first mounting interface 100 for receiving fasteners and the second mounting interface 200 for receiving the connecting part or fastener of the bracket can be different types of mounting interfaces. They have different structures to accommodate different types of connectors (specifically, they are respectively suitable for accommodating the connecting part or fastener of fasteners and brackets) so that the housing 10 can be installed to the window frame 2 of the window by means of fasteners or brackets.

[0065] In some embodiments, the housing 10 is configured to be connected to the window frame 2 of the window via mounting tabs. The housing 10 can be fixed to the mounting tabs, for example, by adhesive bonding or fastening. A single or two mounting tabs can be fixed to one of the front surface 110, rear surface 120, upper surface, and lower surface of the housing 10, with the single or two mounting tabs protruding from the left and right sides of that surface. The protrusions of the mounting tabs beyond the surface are provided with orifices for receiving tab fasteners, allowing the mounting tabs to be fixed to the window frame 2 via tab fasteners, thereby installing the housing 10 to the window frame, and thus allowing the electric window opener 1 to be installed to the window frame 2 via the mounting tabs. The housing 10 can be installed inside or outside the window frame 2 via mounting tabs. For example, two mounting tabs can be fixed to the upper surface of the housing 10 and protrude from the left and right sides of the upper surface. The electric window opener 1 is placed inside the window frame 2 through the opening of the window frame 2, and then the protrusions of the mounting tabs beyond the upper surface of the housing 10 are fixed to the top of the window frame 2 by tab fasteners, thereby installing the electric window opener 1 inside the window frame 2. Similarly, two mounting tabs can be fixed to the front surface 110 or the rear surface 120 of the housing 10 and protrude from the left and right sides of the front surface 110 or the rear surface 120, and then the protrusions of the mounting tabs beyond the front surface 110 or the rear surface 120 of the housing 10 are fixed to the outside of the window frame 2 by tab fasteners, thereby installing the electric window opener 1 outside the window frame 2.

[0066] In summary, the housing 10 can be connected to the window frame 2 of the window via at least two types of connectors (fasteners, brackets, and mounting tabs). Specifically, the housing 10 can be connected to the window frame 2 in at least two of the following ways: by receiving fasteners into the first mounting interface 100 of the housing 10, the housing 10 is mounted to the window frame 2 via fasteners; by receiving the connector / fixture of the bracket into the second mounting interface 200 of the housing 10, the housing 10 is mounted to the window frame 2 via a bracket; and by fixing the housing 10 to the mounting tab, the housing 10 is mounted to the window frame via a mounting tab. Therefore, the electric window opener 1 can be installed to the window frame 2 of the window via different connectors according to actual needs, making the installation method of the electric window opener 1 flexible, adaptable, and versatile.

[0067] It should be noted that the fasteners, brackets and mounting tabs described in this utility model are different types of connectors, while fastening screws, fastening bolts, rivets and pins are all fasteners and belong to the same type of connector. The electric window opener 1 of this utility model can be connected to the window frame 2 of the window through at least two of the fasteners, brackets and mounting tabs.

[0068] like Figure 2As shown, the electric window opener according to this utility model may include a control plate 60 and a control plate support 70 for supporting the control plate 60. The chain member 50 and the control plate 60 are respectively disposed on opposite sides of the control plate support 70, so that the control plate support 70 also serves to separate the control plate 60 from the chain member 50, thereby avoiding damage to the control plate 60.

[0069] like Figure 15 and Figure 16 As shown, the electric window opener 1 of this utility model also includes a wiring harness 80 (also called an input wiring harness) and another wiring harness 90 (also called an output wiring harness). The wiring harness 80 (input wiring harness) enters the interior of the housing 10 from the left end (the end near the motor assembly 20) and extends into the control board 60 within the housing, connecting to the end of the control board 60 near the gear assembly 30. The other wiring harness 90 (output wiring harness) connects to the end of the control board 60 away from the gear assembly 30 and extends to the right end of the housing 10 (the end near the control board 60) and extends out from the right end of the housing 10.

[0070] like Figures 12 to 16 As shown, a guide 15 for guiding the wiring harness 80 is provided inside the housing 10. The guide 15 extends near the top of the internal space of the housing 10 and near the gear assembly 30 and sprocket assembly 40. The guide 15 alone defines the guiding space for guiding the wiring harness 80, thus spatially separating the wiring harness from the gear assembly 30 and sprocket assembly 40. In existing electric window openers, the wiring harness usually passes through the outside, or through the inside without a separator, or even if there is a separator, the separator itself cannot independently define the guiding space. This reduces the aesthetics of the electric window opener, and the wiring harness is easily damaged by external influences. In addition, the wiring harness is prone to interference with internal components, which is detrimental to the operation of internal components, and the wiring harness located inside is also prone to damage. In the electric window opener 1 of this utility model, by setting a guide 15, the wire harness 80 is constrained in the guide space defined by the individual guide 15, so that an independent space for the wire harness 80 can be formed by the individual guide 15, thereby preventing interference between the gear assembly 30 and the sprocket assembly 40 and the wire harness 80, and also preventing possible interference and friction between the wire harness 80 and the inner surface of the top of the housing. Compared with related technologies, the aesthetics of the electric window opener are improved and the wire harness is further effectively protected.

[0071] In some implementations, such as Figure 14As shown, the guide 15 includes two integral curved plates 150. The two curved plates 150 have the same curvature and together define the guide space, making the guide 15 of this invention simple in structure and easy to manufacture. However, it is conceivable that in embodiments of this invention not shown, each curved plate 150 may also be composed of multiple discontinuous segments, as long as the overall curvature of the two curved plates 150 constructed in this way is substantially the same.

[0072] In some implementations, such as Figure 14 and Figure 16 As shown, the guide 15 also includes a cover 151 located below the two curved plates 150. The cover 151 has an arc-shaped cavity that is recessed from bottom to top. This arc-shaped cavity can accommodate a portion of the input gear 41 of the sprocket assembly 40, thereby further separating the sprocket assembly 40 from the wire harness 80 located between the two curved plates 150, and thus more effectively protecting the wire harness. In some embodiments, the cover 151 may be integrally formed with the lower curved plate.

[0073] In some implementations, such as Figure 14 As shown, each bending plate 150 includes: a straight or generally straight first section 150a, a second section 150b that bends downward from one end of the first section 150a, and a third section 150c that extends straight or bends slightly upward from one end of the second section 150b. This allows the wiring harness 80 to smoothly transition within the guide space defined by the two bending plates 150, from being straight-guided in the upper first section to being downward-guided in the middle second section, and then smoothly transitioning to being straight-guided or slightly upward-guided in the lower third section, to connect to the control plate 60. However, it is conceivable that in embodiments of the present invention not shown, the bending plates 150 can have any suitable shape, as long as they can space the wiring harness 80 from the gear assembly 30 and sprocket assembly 40 below.

[0074] In some implementations, such as Figure 14 As shown, the first section 150a of the two curved plates 150 is parallel to the upper surface of the housing 10, and the first section 150a of the upper curved plate 150 abuts against the inner surface of the top of the housing 10, so that the wire harness 80 runs close to the inner surface of the top of the housing 10, thereby more effectively separating the wire harness 80 from the gear assembly 30 and sprocket assembly 40 below, thus more effectively protecting the wire harness 80 and saving internal space of the housing 10.

[0075] In some implementations, such as Figure 14As shown, the guide 15 is integrally formed with the control plate support 70 on the side of the control plate support 70 where the control plate 60 is located, thereby saving installation steps and thus reducing the manufacturing cost of the electric window opener 1. Preferably, one end of the guide 15 (specifically, the end of the lower bending section 150c of each bending plate 150) is adjacent to or abuts against the end of the control plate 60, so that the end of the wiring harness 80 extending from the guide 15 is directly electrically connected to the control plate 60, thereby effectively protecting the wiring harness 80.

[0076] However, it is conceivable that in embodiments of this utility model not shown, the guide 15 may not be integrally formed with the control board support 70, but rather integrally formed with the inner surface of the top of the housing 10, thereby separating the wiring harness 80 from the components below.

[0077] In some implementations, such as Figure 15 and Figure 16 As shown, the electric window opener 1 also includes a motor support 21 for supporting the motor assembly 20. The motor support 21 is disposed inside the housing 10 and has a support plate 210 located on the upper side of the motor support 21 (forming the upper edge of the motor support 21) and / or a tab 220 located on the right side of the motor support 21 (the side closer to the gear assembly 30). The support plate 210 and / or the tab 220 can also be used to support the wiring harness 80, so that after the wiring harness 80 extends from the side of the guide 15 away from the control plate 60, it can pass over the support plate 210 and / or the tab 220 of the motor support 21, thereby spatially separating the wiring harness 80 from the components (motor, etc.) below it, thereby preventing damage to the wiring harness 80.

[0078] According to a second aspect of the present invention, a window is provided, the window including the electric window opener 1 as described above. According to the present invention, the window can be a building window, specifically a window installed on a roof (flat roof window or pitched roof window) or a vertical window.

[0079] It should be noted that, in this application, the use of directional terms such as "upper," "lower," "front," "back," "left," and "right" is for the convenience of describing this application with reference to the accompanying drawings and is not intended to limit the present invention.

[0080] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the specific embodiments described and shown herein. Without departing from the scope defined by the claims, those skilled in the art can make various modifications and combinations to the exemplary embodiments and the various features therein.
