[0055] As Figures 1 to 5As shown, the upper frame structure of the electric sliding door provided by the utility model is an embodiment. In the description of the utility model, for the upper frame structure, the "outdoor" side is defined as Figure 2 the left side of the paper, the "indoor" side is defined as Figure 2 the right side of the paper, Figure 2 the left and right directions of the paper are the indoor and outdoor directions, when the upper frame structure is installed and used, the outdoor side and the indoor side are located in the outdoor and indoor separated by the electric sliding door respectively; the "upper" side is defined as Figure 2 the upper side of the paper, the "lower" side is defined as Figure 2 the lower side of the paper, and the "up and down direction" is the height direction of the electric sliding door; the "left" side is defined as Figure 2 the left side of the paper, and the "right" side is defined as Figure 2 the right side of the paper, and the "left and right direction" is the width direction of the upper frame 1 and the upper frame rail 2 extending horizontally, which is also the sliding direction of the electric sliding door 200.

[0056] Referring to Figure 1 and Figure 2 , the upper frame structure of the electric sliding door of the embodiment comprises an upper frame 1, an upper frame rail 2 and a cover plate 3.

[0057] The upper frame 1 constitutes the upper end part of the electric sliding door frame. The electric components 100 are accommodated in the upper frame 1, and the electric components 100 are arranged in the upper frame 1 to realize the hidden design of the electric components 100. The electric components 100 have a driving motor 101 and a transmission assembly 102 connected with the output shaft of the driving motor 101, the output shaft of the driving motor 101 provides a rotary driving force, and the transmission assembly 102 converts the rotary motion of the output shaft of the driving motor 101 into linear motion along the width direction of the upper frame 1. The structure of the transmission assembly 102 is not limited, for example, a synchronous pulley transmission structure can be used.

[0058] The upper frame guide rails 2 are provided with two upper frame guide rails 2a and 2b. The two upper frame guide rails 2 are oppositely arranged along the indoor and outdoor direction, and the upper frame guide rail 2a is close to the outdoor side and the upper frame guide rail 2b is close to the indoor side, and the two upper frame guide rails 2 have a spacing therebetween. The two upper frame guide rails 2 are detachably mounted at the lower end of the upper frame 1, and the upper end of the upper frame guide rail 2a and the upper end of the upper frame guide rail 2b are detachably assembled and connected with the upper frame 1, so that the two upper frame guide rails 2 and the upper frame 1 are designed in a split type. At least one upper frame guide rail 2 is used to connect the electric sliding door 200, that is, one of the two upper frame guide rails 2 is used to connect the electric sliding door 200, and the other can be used to connect the electric sliding door, or can be used to connect other types of doors, such as connecting a manual sliding door, or connecting a fixed door, or directly connecting glass, etc. Among them, the electric sliding door 200 is driven by the electric component 100 to slide along the width direction of the upper frame guide rail 2, the manual sliding door is manually pushed and pulled to slide along the width direction of the upper frame guide rail 2, the fixed door is fixedly arranged with the upper frame guide rail 2, and the upper frame guide rail 2 directly connected with the glass means that the upper end of the door glass is directly embedded in the lower end of the upper frame guide rail 2. Since the upper end connection structure of the electric sliding door 200, the manual sliding door, the fixed door and the glass is different, the lower end structure of the upper frame guide rail 2 matched with the connection is also designed to be different, so that the upper frame guide rail 2 (such as the upper frame guide rail 2a shown in Figure 2 ) used to connect the electric sliding door 200 and the upper frame guide rail 2 (such as the upper frame guide rail 2b shown in Figure 2 , and the manual sliding door or the fixed door or the glass is not shown in Figure 2 ) used to connect the manual sliding door or the fixed door or the glass have different lower end structures. Since the two upper frame guide rails 2 and the upper frame 1 are designed in a split type, the upper frame guide rail 2 can be easily disassembled and assembled, and different types of upper frame guide rails 2 can be selected and replaced to adapt to different types of doors, so that various doors can be freely combined. For example, only the electric sliding door 200 can be arranged on the outdoor side, the manual sliding door or the fixed door or the door directly connected with the glass by the upper frame guide rail 2 can be arranged on the indoor side, or only the electric sliding door 200 can be arranged on the indoor side, the manual sliding door or the fixed door or the door directly connected with the glass by the upper frame guide rail 2 can be arranged on the outdoor side, or the electric sliding door 200 can be arranged on the indoor side and the outdoor side.

[0059] The upper end of the upper frame 1 is internally formed with a receiving cavity for accommodating the driving motor 101 of the electric component 100, and the driving motor 101 is fixedly installed in the receiving cavity. The lower end of the upper frame 1 is internally formed with a downwardly open receiving space for accommodating the two upper frame guide rails 2, and the transmission assembly 102 of the electric component 100 is arranged in the spacing region between the two upper frame guide rails 2 in the receiving space. In order to avoid that the transmission assembly 102 and the driving motor 101 of the electric component 100 can be seen from the spacing region between the two upper frame guide rails 2 when looking upwardly from below to the upper frame 1, the upper frame structure of the present embodiment is additionally provided with a cover plate 3, which is arranged between the two upper frame guide rails 2 and covers the electric component 100 from below. The cover plate 3 is preferably made of resin material. Since the transmission assembly 102 of the electric component 100 reciprocatingly moves linearly along the width direction of the upper frame 1 to drive the electric sliding door 200 to slide along the width direction of the upper frame guide rail 2, the cover plate 3 extends along the width direction of the upper frame guide rail 2, so that the cover plate 3 can cover the driving motor 101 and the transmission assembly 102 of the electric component 100. Thus, when looking upwardly from below to the upper frame 1, the electric component 100 will not be seen due to the covering of the cover plate 3, and the full concealment design of the electric component 100 is achieved, so that the uniformity of the overall appearance of the electric sliding door can be achieved, and the appearance design property of the electric sliding door is improved.

[0060] In the present embodiment, the electric component 100 is connected to the electric sliding door 200 through the connecting member 300 arranged between the two upper frame guide rails 2 to drive the electric sliding door 200 to slide along the upper frame guide rail 2. The upper end of the connecting member 300 can be connected to the transmission assembly 102 of the electric component 100, for example, connected to the belt of the synchronous belt transmission structure, and the lower end of the connecting member 300 is connected to the upper end of the electric sliding door 200, so that the reciprocating linear motion of the transmission assembly 102 of the electric component 100 can be transmitted to the electric sliding door 200 to drive the electric sliding door 200 to synchronously slide. Since the cover plate 3 is arranged between the two upper frame guide rails 2 and located below the electric component 100, and the electric sliding door 200 is connected to the lower end of the upper frame guide rail 2 and located below the cover plate 3, the connecting member 300 needs to pass through the cover plate 3 to connect the electric component 100 and the electric sliding door 200. Thus, the cover plate 3 is provided with a cutout 31 (see FIG. 2) for the connecting member 300 to pass through and slide. Figure 3), the cutout 31 extends along the width direction of the cover plate 3, and the connecting piece 300 can be slidably arranged in the cutout 31 on the cover plate 3 along the width direction of the cover plate 3, so that the cover plate 3 does not interfere with the sliding movement of the connecting piece 300. In order to ensure the air tightness and water tightness of the whole upper frame structure, the cutout blocking strip 4 is arranged on the upper frame rail 2, and the cutout blocking strip 4 blocks the cutout 31 on the cover plate 3, so that the cutout 31 does not affect the overall performance of the upper frame structure. Preferably, the long groove 21 is arranged on the upper frame rail 2, and the cutout blocking strip 4 is installed in the long groove 21. Of course, the cutout blocking strip 4 can also be installed and fixed with the upper frame rail 2 in other ways, such as adhesive fixing, screw fixing, etc. Since the connecting piece 300 is connected to the upper end of the electric sliding door 200, the connecting piece 300 is closer to the upper frame rail 2 (such as the upper frame rail 2a) of the electric sliding door 200, and the cutout 31 on the cover plate 3 is also closer to the upper frame rail 2 (such as the upper frame rail 2a) of the electric sliding door 200, so the cutout blocking strip 4 is preferably arranged on the upper frame rail 2 (such as the upper frame rail 2a) of the electric sliding door 200, and the upper frame rail 2 (such as the upper frame rail 2b) of the manual sliding door or fixed door or glass can not be provided with the cutout blocking strip 4. In order to ensure full coverage of the cutout 31, the cutout blocking strip 4 extends along the width direction of the upper frame rail 2 and the extension size is not less than the extension size of the cutout 31 along the width direction of the cover plate 3. In order to improve the overall appearance, the cutout blocking strip 4 is arranged above the cover plate 3, so as to be blocked by the cover plate 3. The cutout blocking strip 4 is preferably a wool strip, and one side of the wool strip can be fixed on the upper frame rail 2, such as embedded and fixed in the long groove 21 or adhesively fixed or screw-fixed with the upper frame rail 2, and the other side of the wool strip blocks the cutout 31, and the flexible nature of the wool strip does not affect the arrangement and sliding of the connecting piece 300 in the cutout 31.

[0061] In the embodiment, the two upper frame guide rails 2 and the upper frame 1 are designed in a split type, which can facilitate the assembly of the cutout shielding strip 4, the cover plate 3 and the upper frame guide rail 2. Preferably, the two upper frame guide rails 2 are each provided with a limiting clamping groove 25 on the opposite side surface, the cover plate 3 is provided with a connecting part 32 on the two sides in the indoor and outdoor directions, the two side connecting parts 32 of the cover plate 3 are respectively inserted or clamped into the limiting clamping grooves 25 provided on the opposite side surfaces of the two upper frame guide rails 2, and the cover plate 3 is detachably assembled and fixed with the two upper frame guide rails 2. During assembly, the cutout shielding strip 4 can be first installed on the upper frame guide rail 2 (such as the upper frame guide rail 2a) connected with the electric sliding door 200, then the upper frame guide rail 2 (such as the upper frame guide rail 2a) is installed to one side (such as the outdoor side) at the lower end of the upper frame 1, then the side connecting part 32 of the cover plate 3 closer to the cutout 31 is inserted or clamped into the limiting clamping groove 25 on the upper frame guide rail 2 (such as the upper frame guide rail 2a), and then the other upper frame guide rail 2 (such as the upper frame guide rail 2b) is installed to the other side (such as the indoor side) at the lower end of the upper frame 1, while the connecting part 32 on the other side of the cover plate 3 is clamped into the limiting clamping groove 25 on the upper frame guide rail 2 (such as the upper frame guide rail 2b), thereby completing the installation of the two upper frame guide rails 2 and the cover plate 3 at the lower end of the upper frame 1.

[0062] Referring to Figure 2 In the embodiment, preferably, the two ends of the upper frame guide rail 2 in the indoor and outdoor directions are connected with the upper frame 1 through the clamping structure 5 and the guide rail fastener 6 respectively. The guide rail fastener 6 is preferably a screw. The clamping structure 5 connects one end of the upper frame guide rail 2 in the indoor and outdoor directions with the upper frame 1, so that the connection and fixation of the upper frame guide rail 2 and the upper frame 1 only need to be achieved by arranging the guide rail fastener 6 at the other end opposite to the clamping structure 5 in the indoor and outdoor directions, which can reduce the number of guide rail fasteners 6, thereby reducing the number of assembly components and the machining process, and making the installation and combination of the upper frame guide rail 2 and the upper frame 1 more convenient.

[0063] Preferably, the clamping structure 5 is located at one end of the upper frame guide rail 2 in the indoor and outdoor directions close to the cover plate 3, and the guide rail fastener 6 is located at the other end of the upper frame guide rail 2 in the indoor and outdoor directions away from the cover plate 3, thereby being away from the electric component 100, so that the installation of the guide rail fastener 6 does not interfere with the electric component 100, avoids damaging the electric component 100 inside the upper frame 1 or affecting the installation precision of the electric component 100 during the installation and combination of the upper frame guide rail 2 and the upper frame 1, and can ensure the overall performance of the upper frame structure.

[0064] In the embodiment, preferably, the clamping structure 5 includes a clamping groove part 51 and a clamping part 52, and the clamping part 52 and the clamping groove part 51 are clamped with each other. One of the upper frame 1 and the upper frame guide rail 2 is provided with the clamping groove part 51, and the other is provided with the clamping part 52. Preferably, as shown in Figure 2As shown, the upper frame rail 2 is provided with a clamping portion 52 at the upper end of the end close to the cover plate 3 in the indoor-outdoor direction, and the upper frame 1 is provided with a clamping groove portion 51 at the position where the upper frame rail 2 is connected to the upper end of the end close to the cover plate 3 in the indoor-outdoor direction, and the clamping portion 52 is clamped into the clamping groove portion 51 in the indoor-outdoor direction, so as to realize the mutual clamping of the upper end of the end of the upper frame rail 2 close to the cover plate 3 in the indoor-outdoor direction and the upper frame 1.

[0065] In order to ensure the wind pressure resistance of the upper frame structure as a whole, preferably, a gap is provided between the clamping portion 52 and the clamping groove portion 51 of the clamping structure 5 in the indoor-outdoor direction, which provides a certain deformation tolerance space for the slight deformation of the upper frame rail 2 under the action of wind pressure (positive pressure from the outdoor side to the indoor side or negative pressure from the indoor side to the outdoor side), so as to inhibit the deformation of the upper frame rail 2 and ensure the stability of the installation and combination of the upper frame rail 2 and the upper frame 1 under the action of wind pressure.

[0066] Further, the upper end of the upper frame rail 2 is provided with an abutting piece 22 close to the clamping structure 5, which protrudes upward and abuts against the upper frame 1, and the abutting piece 22 extends along the width direction of the upper frame rail 2. The abutting piece 22 plays a role in increasing the strength and inhibiting the deformation of the upper frame rail 2 under the action of wind pressure, so as to ensure the wind pressure resistance of the upper frame structure as a whole.

[0067] In the embodiment, as shown in Figure 2 , the lower end of the driving motor 101 of the electric component 100 is connected to the upper frame 1 through a motor fastener 7, which is preferably a screw. In order to avoid interference, preferably, a avoiding space 8 is provided between the upper frame rail 2 and the upper frame 1 to avoid the motor fastener 7, so as to avoid the interference between the motor fastener 7 connected to the driving motor 101 on the upper frame 1 and the upper frame rail 2 when the upper frame rail 2 and the upper frame 1 are installed and combined, thereby ensuring the correct assembly of the electric component 100, the upper frame 1 and the upper frame rail 2.

[0068] Preferably, as shown in Figure 2 , the driving motor 101 of the electric component 100 is further supported inside the upper frame 1 by a motor support plate 9, which is arranged between the upper end of the upper frame rail 2 and the upper frame 1 and is fastened to the upper frame 1 by a screw, thereby playing a supporting role on the driving motor 101 accommodated in the accommodating cavity inside the upper end of the upper frame 1. In order to avoid interference, as shown in Figure 4 and Figure 5 , an avoiding groove 23 is provided on the upper end face of the upper frame rail 2 to avoid the motor support plate 9, which is used to accommodate the motor support plate 9 connected to the upper frame 1 when the upper end of the upper frame rail 2 and the upper frame 1 are installed and combined, so as to avoid the interference between the motor support plate 9 and the upper frame rail 2, thereby ensuring the correct assembly of the electric component 100, the upper frame 1 and the upper frame rail 2.

[0069] As shown in Figure 4 andFigure 5 In the embodiment, preferably, the driving motor 101 of the electric component 100 is arranged in one end (e.g. the left end) of the upper frame 1 in the sliding direction of the electric sliding door 200, and both the upper frame guide rail 2 and the cover plate 3 are cut to form a segmented structure near the driving motor 101, so that the upper frame guide rail 2 and the cover plate 3 each have a short section below the driving motor 101 and a long section opposite to the short section in the width direction, and the long section is mainly below the transmission assembly 102. Thus, the upper frame guide rail 2 and the cover plate 3 each have a split structure formed by the long section and the short section opposite to each other in the width direction. Thus, when the driving motor 101 needs to be disassembled for maintenance in the later maintenance stage of the electric component 100, only the short section of the upper frame guide rail 2 and the cover plate 3 below the driving motor 101 needs to be disassembled, without disassembling the upper frame guide rail 2 and the cover plate 3 as a whole, so that the disassembly and maintenance of the driving motor 101 can be realized, thereby making the later maintenance of the driving motor 101 more convenient, improving the maintenance efficiency, and reducing the labor cost of maintenance. Since the upper frame guide rail 2 is cut to form a segmented structure, the cut-off blocking strip 4 arranged on the upper frame guide rail 2 is also cut to form a segmented structure, so that the cut-off blocking strip 4 does not need to be disassembled as a whole when the driving motor 101 is maintained.

[0070] Specifically, the maintenance and disassembly process of the driving motor 101 is as follows: (1) disassemble the short section of one upper frame guide rail 2 (e.g. the upper frame guide rail 2b); (2) disassemble the short section of the cover plate 3; (3) disassemble the short section of the other upper frame guide rail 2 (e.g. the upper frame guide rail 2a), and the cut-off blocking strip 4 in the short section is disassembled; (4) disassemble the motor supporting plate 9; (5) disassemble the driving motor 101 and replace it. The installation process of the replaced driving motor 101 is the reverse operation of the above processes (1) to (5).

[0071] In the upper frame structure of the electric sliding door of the embodiment, referring to Figure 2For the upper frame guide rail 2 (such as the upper frame guide rail 2a) connected to the electric sliding door 200, the lower end of the upper frame guide rail 2 is provided with a mounting port 24 for mounting a door handle electric transmission component. The door handle electric transmission component is a conventional structure of the electric sliding door, which is used to realize the lifting and lowering of the electric sliding door 200 and synchronously slide with the electric sliding door 200. The door handle electric transmission component has internal structural parts accommodated in the upper frame guide rail 2. In order to realize the installation of the door handle electric transmission component in the upper frame guide rail 2 and not hinder the sliding of the electric sliding door 200, the mounting port 24 is arranged at the lower end of the upper frame guide rail 2 to avoid the door handle electric transmission component, and the mounting port 24 extends along the width direction of the upper frame guide rail 2. In order to ensure the air tightness and water tightness of the whole upper frame structure, a mounting port shielding strip 10 is mounted in the mounting port 24, and the mounting port shielding strip 10 shields the mounting port 24, so that the mounting port 24 does not affect the overall performance of the upper frame structure. In order to ensure full coverage of the mounting port 24, the mounting port shielding strip 10 extends along the width direction of the upper frame guide rail 2 and the extension size is not less than the size of the mounting port 24 extending along the width direction of the upper frame guide rail 2. The mounting port shielding strip 10 is preferably composed of two wool strips which are opposite to each other in the indoor and outdoor direction. The internal structural parts of the door handle electric transmission component pass between the two wool strips, and the flexible characteristics of the wool strips do not affect the relative sliding of the internal structural parts of the door handle electric transmission component and the upper frame guide rail 2. Since the upper frame guide rail 2 is cut into a segmented structure, the mounting port 24 on the upper frame guide rail 2 is also cut into a segmented structure, and preferably, the mounting port shielding strip 10 mounted in the mounting port 24 is also cut into a segmented structure, so that the mounting port shielding strip 10 does not need to be disassembled as a whole when the driving motor 101 is maintained.
