[0002] A sill is a grooved metal pedal at the entrance of an elevator car or landing door for entering and exiting the car, which is used to support and guide the movement of the elevator door. It is an important part of the elevator system and is directly related to the safety and stability of the elevator. The sill support assembly is an important auxiliary component in the elevator sill system, mainly used to support and fix the elevator sill, and plays a crucial role in ensuring the safe operation of the elevator and the comfortable experience of passengers.

[0003] In the currently existing sill support assemblies, the part that is in direct contact with the sill and used to support the sill is generally of an integral design, that is, the sill is supported by a long strip-shaped structure extending along the length direction of the sill. The integral support structure has certain advantages in the supporting effect, but has disadvantages in terms of cost and economy. In scenarios such as small elevators where the sill does not need to have a large load-bearing capacity, the integral support structure has a low cost performance.

[0004] Based on this, the utility model hopes to propose a solution to ensure a good supporting effect on the sill while keeping the cost low. Summary of the Utility Model

[0031] Embodiment 1

[0032] Please refer to Figures 1 to 4 , in this embodiment, a sill support assembly is provided, which includes a plurality of support plates 1. The plurality of support plates 1 are arranged at intervals along the length direction of the external sill 9 at the lower part of the external sill 9 to support the external sill 9. One side edge of the support plate 1 is bent upward to form a first bent portion 2. The first bent portion 2 can improve the structural strength of the support plate 1, and the first bent portion 2 can be used to further support the external sill 9. The other side edge of the support plate 1 is bent downward to form a second bent portion 3. The second bent portion 3 can also improve the structural strength of the support plate 1, thereby enhancing the support effect of the support plate 1 on the external sill 9, and the second bent portion 3 can also be used to connect external expansion parts to realize the expansion of functions through connecting the expansion parts.

[0033] It can be understood that for the sill support assembly provided in this embodiment, by arranging a plurality of support plates 1 at intervals at the lower part of the external sill 9, the external sill 9 can be supported in a segmented manner. Compared with the traditional integral support, the segmented support can well save the material cost and has good economy. In addition, based on the reasonable structural design of the support plate 1, the external sill 9 can be well supported while saving costs. Specifically, on the one hand, the formation of the first bent portion 2 and the second bent portion 3 increases the structural strength of the support plate 1, thereby improving the support effect of the support plate 1 on the external sill 9; on the other hand, the first bent portion 2 can also directly abut and support the external sill 9, thereby further strengthening the support effect on the external sill 9.

[0034] Exemplarily, please refer to Figure 3 , a welding notch 11 can be formed on the support plate 1. The support plate 1 is fixedly connected to the lower part of the external sill 9 by welding the edge of the welding notch 11. In actual application, the distance between adjacent support plates 1 can be determined by welding the support plate 1 to a specific position at the lower part of the external sill 9.

[0035] Optionally, the number of the support plates 1 and the distance between adjacent support plates 1 can be designed according to the actual situation and are not specifically limited here. Exemplarily, the distance between adjacent support plates 1 can be between 10 cm and 45 cm. The closer the distance between adjacent support plates 1 is, the better the support effect on the external sill 9 is, but the total number of the required support plates 1 is more. Optionally, the plurality of support plates 1 can be arranged at equal intervals, or there can be multiple intervals, which are not specifically limited here.

[0036] Optionally, the bending angles of the first bent portion 2 and the second bent portion 3 can also be adaptively selected according to the actual situation. Preferably, refer to Figure 2 , both the first bent portion 2 and the second bent portion 3 are bent by 90°.

[0037] Furthermore, the first bending portion 2 can also be fixedly connected to the external sill 9. For example, the upper end of the first bending portion 2 can be welded to the external sill 9, thereby improving the connection stability with the external sill 9 and further enhancing the support effect on the external sill 9.

[0038] Furthermore, please refer to Figures 1 to 3 , and it may further include a plurality of bearing members 4. Different bearing members 4 are fixedly connected to the lower parts of different support plates 1. The bearing members 4 are used for fixedly connecting external load-bearing objects. The load-bearing object is, for example, a load-bearing wall in an elevator shaft. On the one hand, the bearing member 4 is connected to the load-bearing wall, and on the other hand, it is supported on the support plate 1, so that the supporting force of the load-bearing wall is finally transmitted to the external sill 9 through the support plate 1.

[0039] Specifically, please refer to Figure 2 and Figure 4 , a plurality of fixing holes 41 are spaced apart along the width direction of the support plate 1 on the bearing member 4, and connection holes 12 corresponding to the fixing holes 41 are formed on the support plate 1.

[0040] It further includes a fixing assembly 5. The fixing assembly 5 passes through the fixing holes 41 and the connection holes 12, and the fixing assembly 5 abuts and presses the side of the support plate 1 away from the bearing member 4, and abuts and presses the side of the bearing member 4 away from the support plate 1, thereby fixedly connecting the support plate 1 and the bearing member 4 to each other.

[0041] Before fixedly connecting the support plate 1 and the bearing member 4 to each other, the connection holes 12 of the support plate 1 can be made to correspond to different fixing holes 41 on the bearing member 4, so as to adjust the position of the bearing member 4 in the width direction of the support plate 1, which has good flexibility.

[0042] Preferably, the fixing holes 41 and the connection holes 12 may both include waist-shaped holes, and the extending direction of the waist-shaped holes is the same as the length direction of the support plate 1. Based on this, the position of the bearing member 4 in the length direction of the support plate 1 can also be flexibly adjusted.

[0043] Exemplarily, the fixing assembly 5 may include a bolt 51, a nut 52, and a washer 53. One end of the bolt 51 passes through the fixing hole 41 and the connection hole 12 and is screwed with the nut 52. The other end of the bolt 51 can abut and press the side of the support plate 1 away from the bearing member 4, and the nut 52 presses the side of the bearing member 4 away from the support plate 1, thereby fixedly connecting the support plate 1 and the bearing member 4 to each other. The washer 53 can be arranged between the nut 52 and the bearing member 4 to play a certain buffering role.

[0044] In this embodiment, please refer to Figure 1 and Figure 2, the carrier 4 can be in an "L" shape. One limb of the carrier 4 is connected to the lower part of the support plate 1, and the other limb of the carrier 4 is used for fixedly connecting an external load-bearing object. Exemplarily, the fixing hole 41 described above is opened on one limb of the carrier 4, and an expansion screw hole 42 for installing an expansion screw (not shown in the figure) is opened on the other limb of the carrier 4. The carrier 4 can be fixedly connected to the external load-bearing object through the expansion screw. Further, one or more reinforcing plates 6 can be provided at the "L" - shaped angle of the carrier 4. The reinforcing plates 6 are connected to the "L" - shaped carrier 4 and cooperate to form a triangular structure, making the structure of the carrier 4 more stable and having a better supporting effect on the support plate 1.

[0045] In this embodiment, the extension member may include a baseboard 7. Please refer to Figure 3 , specifically, a plurality of through - holes 71 are opened on the baseboard 7, and screw holes 31 and screws 8 are provided on the second bent portion 3. The screws 8 pass through the through - holes 71 and are screwed into the screw holes 31, thereby fixing the baseboard 7 on the second bent portion 3.
