[0035] Example 1

[0036] Please refer to Figures 1 to 5 This embodiment provides a sill bearing assembly, including a connecting plate 1, a first supporting plate 2, a second supporting plate 3 and a plurality of supporting members 7.

[0037] Specifically, the connecting plate 1 is a long strip structure adapted to the external sill 13, and the upper part of the connecting plate 1 is used to fix the external sill 13, so as to support the external sill 13. The connection method between the connecting plate 1 and the external sill is not specifically limited. For example, please refer to Figure 1 , 2 4, the connection plate 1 may be provided with a welding port 11, and the connection plate 1 may be fixedly connected to the external sill 13 by welding the edge of the welding port 11 to the bottom of the external sill 13. It can be understood that, on the one hand, the provision of the welding port 11 provides space for welding the connection plate 1 to the external sill 13, facilitating welding operations in practical applications. On the other hand, the provision of the welding port 11 reduces the weight of the connection plate 1 and reduces the material cost of the sill bearing assembly.

[0038] Please refer to Figure 3 The first support plate 2 is connected to the connecting plate 1 and extends downwardly from the connecting plate 1. A first preset angle R is formed between the first support plate 2 and the connecting plate 1. 1 . It should be noted that the extension of the first support plate 2 toward the bottom of the connecting plate 1 is not limited to extending vertically downward, and can also be interpreted as extending obliquely downward. Optionally, the first support plate 2 can be connected to the edge of the connecting plate 1 or any position on the lower side of the connecting plate 1. The first support plate 2 is connected to the connecting plate 1, and can provide certain support for the connecting plate 1, thereby improving the structural strength of the connecting plate 1, so that the connecting plate 1 has a better supporting effect on the external sill 13, thereby improving the bearing capacity of the external sill 13. The first support plate 2 can also be used to connect to an external expansion piece 4 to provide an interface for further expanding other functional components, and has good flexibility and extensibility.

[0039] The second support plate 3 is connected to the connecting plate 1 and extends upward from the connecting plate 1 to support the external sill 13. A second preset angle R is formed between the second support plate 3 and the connecting plate 1. 2 . Similarly, the second support plate 3 can extend vertically upward or obliquely upward. Optionally, the second support plate 3 can be connected to the edge of the connecting plate 1 or any position on the upper side of the connecting plate 1. It can be seen that the second support plate 3 can further support the external sill 13, thereby further improving the bearing capacity of the external sill 13. Exemplarily, the second support plate 3 can also be welded to the outer wall sill 13, thereby improving the connection stability between the second support plate 3 and the external sill 13.

[0040] A plurality of support members 7 are arranged at intervals at the lower part of the connecting plate 1 along the length direction of the connecting plate 1. The distance between adjacent support members 7 can be set according to actual conditions and is not specifically limited here. The support members 7 are used to connect an external load-bearing object, thereby transmitting the supporting force of the external load-bearing object to the connecting plate 1 to provide support for the connecting plate 1. The external load-bearing object can be, for example, a load-bearing wall in an elevator shaft.

[0041] The sill bearing assembly of this embodiment achieves a good supporting effect on the external sill 13 through the mutual connection and cooperation of the connecting plate 1, the first supporting plate 2 and the second supporting plate 3. Specifically, the first supporting plate 2 is connected to the connecting plate 1 and extends downward, and the structural strength of the connecting plate 1 is improved, thereby improving the supporting effect of the connecting plate 1 on the external sill 13. The second supporting plate 3 directly supports the external sill 13 by extending upward, thereby improving the supporting effect on the external sill 13. The sill bearing assembly of the utility model is simple in structure and low in cost, and can also provide good supporting and bearing effect for the external sill 13, and has good reliability and user experience.

[0042] For example, please refer again to Figure 3 , the first preset angle R 1 and the second preset angle R 2 The angle range of the first preset angle R 1 and the second preset angle R 2 The angles are all 90°. The 90° angle makes it difficult for the first support plate 2 and the second support plate 3 to bend when subjected to force, thereby increasing the overall service life and providing the best support for the external sill 13.

[0043] Furthermore, please combine Figures 1 to 3 , the first support plate 2 can be connected to one side edge of the connecting plate 1 along the length direction of the connecting plate 1, and the second support plate 3 can be connected to the other side edge of the connecting plate 1 along the length direction of the connecting plate 1. The cross-section after the first support plate 2 is connected to the connecting plate 1 and the cross-section after the second support plate 3 is connected to the connecting plate 1 are both "L" shaped.

[0044] Furthermore, the first support plate 2 can be integrally formed with the connecting plate 1, and the second support plate 3 can also be integrally formed with the connecting plate 1, similar to the folding of the two sides of the support plate. The integrally formed design can make the overall structure stronger and can provide better support for the external sill 13.

[0045] For example, please refer to Figure 4The expansion piece 4 may include a foot guard, and the first support plate 2 is provided with a screw hole 21 and a screw 5. Specifically, a through hole 6 corresponding to the screw hole 21 is opened on the foot guard, and the screw 5 passes through the through hole 6 and is screwed to the screw hole 21, thereby fixing the foot guard on the first support plate 2.

[0046] In a specific embodiment, please refer to Figure 3 and Figure 5 , the support member 7 may be in an "L" shape, one limb of the support member 7 and the connecting plate 1 are provided with corresponding waist-shaped holes 8, and also include bolts 9 and nuts 10, one end of the bolt 9 passes through the waist-shaped holes 8 of the two and is connected with the nut 10, so that the support member 7 and the connecting plate 1 are fixed to each other. Preferably, a washer 14 may also be provided between the nut 10 and the support member 7. The extension direction of the waist-shaped hole 8 may be the same as the length direction of the connecting plate 1, so that before being fixed by the bolts 9 and the nuts 10, the position of the support member 7 can be adjusted in the length direction, so as to flexibly adjust the distance between adjacent support members 7 according to actual conditions, and has good flexibility. The other limb of the support member 7 is used to connect an external load-bearing object. For example, the other limb of the support member 7 may also be provided with a waist-shaped hole 8, and an expansion screw (not shown in the figure) may be installed on the waist-shaped hole 8, and the external load-bearing object is connected by fixing with the expansion screw.

[0047] Further, please refer again to Figure 5 A plurality of waist-shaped holes 8 as described above are arranged at intervals along the width direction of the connecting plate 1 on one limb of the support member 7 used for connection with the connecting plate 1, so that before being fixed by bolts 9 and nuts 10, a specific waist-shaped hole 8 on the support member 7 can be selected to correspond to the waist-shaped hole 8 of the connecting plate 1 according to actual conditions, thereby adjusting the position of the support member 7 in the width direction of the connecting plate 1, so that the sill bearing assembly of this embodiment can meet different specification requirements and usage scenarios, and the flexibility is further improved.

[0048] Furthermore, a reinforcing plate 12 may be provided at the "L"-shaped angle of the support member 7. Optionally, the number of reinforcing plates 12 may be one or more. The reinforcing plate 12 may be connected to the "L"-shaped support member 7 and cooperate to form a triangular structure, so that the structure of the support member 7 is more stable, and the supporting effect on the connecting plate 1 is better, thereby ultimately improving the supporting effect on the external sill 13.

Figure 3The lower part of the sill (refer to the external sill 13) is fixedly connected to the connecting plate 1 to be supported by the connecting plate 1, and the second supporting plate 3 is supported on the sill. The sill provided in this embodiment does not need to be supported by a sill bracket with a complex structure. By being connected to a sill bearing assembly with a simple structure, it can also be well supported and supported, while also saving costs to the greatest extent. The sill of this embodiment can be applied to elevators such as supermarket elevators and home elevators that do not require forklifts, and has the advantages of being economical and highly reliable.

[0051] In summary, the utility model provides a sill bearing assembly and a sill including the same, wherein the sill bearing assembly achieves a good supporting effect on the external sill 13 by connecting and cooperating with the connecting plate 1, the first supporting plate 2 and the second supporting plate 3. Specifically, the first supporting plate 2 is connected to the connecting plate 1 and extends downward, and the supporting effect of the connecting plate 1 on the external sill 13 is improved by improving the structural strength of the connecting plate 1.
