[0047] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0048] Reference Figure 1 As shown, the elevator car includes a car bottom assembly 100, a column assembly 200, a car wall assembly 300, an elevator door assembly 400, a car top assembly 500, an upper beam assembly 600, an upper roller guide shoe assembly 700, a lower roller guide shoe assembly 800, a safety clamp assembly 900, and a lifting mechanism 101. The car bottom assembly 100 includes a car bottom 110; the column assembly 200 is disposed on the car bottom 110; the car wall assembly 300 is disposed on the car bottom 110 and located between the column assemblies 200; the elevator door assembly 400 is disposed on the car bottom 110 and connected to the car wall assembly 300 on both sides; the car top assembly 500 is disposed on the side of the car wall assembly 300 away from the car bottom 110; the upper beam assembly 600 is disposed on the side of the car top assembly 500 away from the car wall assembly 300 and its two ends are connected to the ends of the column assemblies 200 away from the car bottom 110. The upper roller guide shoe assembly 700 is located on both sides of the column assembly 200 away from the car wall assembly 300, and at the end of the column assembly 200 near the car top assembly 500; the lower roller guide shoe assembly 800 is located on both sides of the column assembly 200 away from the car wall assembly 300, and at the end of the column assembly 200 near the car bottom 110, and the lower roller guide shoe assembly 800 is flush with the car bottom 110; the safety clamp assembly 900 is located on both sides of the column assembly 200 away from the car wall assembly 300, and below the upper roller guide shoe assembly 700; the lifting mechanism 101 is located on one side of the car top assembly 500 away from the car wall assembly 300 and next to the upper beam assembly 600, the drive end of the lifting mechanism 101 is connected to the safety clamp assembly 900, and the lifting mechanism 101 is used to drive the safety clamp assembly 900 to close.

[0049] In the above embodiments, the column assembly 200 serves as the main load-bearing support, forming a stable frame with the car bottom 110, car wall assembly 300, and car top assembly 500, while the upper beam assembly 600 further enhances the overall rigidity. The column assembly 200 is directly connected to the car bottom 110, increasing the utilization rate of the elevator shaft space and meeting the installation requirements of narrow shafts. By placing the lower roller guide shoe assembly 800 on both sides of the column assembly 200 near the car bottom 110 and flush with it, the lower roller guide shoe assembly 800 can ensure guiding stability while reducing the depth of the elevator pit. By placing the lifting mechanism 101 and the safety clamp assembly 900 on both sides of the column assembly 200 near the car top, the depth of the elevator pit can be reduced while also making the installation and commissioning of the safety clamp assembly 900 more convenient. Compared with the prior art, the embodiments of this application can improve the utilization rate of the elevator shaft space and reduce the depth of the elevator pit.

[0050] Understandably, referring to Figure 1 , 2 As shown, the column assembly 200 includes a first column 210 and a second column 220. One end of the first column 210 and one end of the second column 220 are respectively connected to the opposite sides of the car floor 110, and the first column 210 and the second column 220 are aligned. By directly connecting the first column 210 and the second column 220 to the car floor 110, compared with the prior art, the lower beam is eliminated, which increases the utilization rate of elevator shaft space while ensuring the overall structural rigidity.

[0051] For example, such as Figure 1 , 2 As shown, the first column 210 and the second column 220 are detachably connected to the car bottom 110. The connection method can be a screw and nut fixed connection, which facilitates transportation and assembly and reduces the difficulty and cost of car installation.

[0052] Understandably, referring to Figure 1 , 2 As shown, the car wall assembly 300 includes a first side wall 310, a second side wall 320, and a rear wall 330. The first side wall 310 is disposed on the car floor 110 and located beside the first column 210. The second side wall 320 is disposed on the car floor 110 and located beside the second column 220. The rear wall 330 is disposed on the side of the car floor 110 away from the elevator door assembly 400. Through the reasonable arrangement of the first side wall 310, the second side wall 320, and the rear wall 330, a stable closed structure is formed, effectively improving the overall rigidity and deformation resistance of the car.

[0053] For example, such as Figure 1 , 2As shown, the first side wall 310, the second side wall 320 and the rear wall 330 are detachably connected to the car bottom 110, which facilitates transportation and assembly and reduces the difficulty and cost of car installation.

[0054] Understandably, referring to Figure 1 , 2 As shown, the lower roller guide shoe assembly 800 includes a first lower roller guide shoe 810 and a second lower roller guide shoe 820. The first lower roller guide shoe 810 is disposed at the end of the first column 210 near the car bottom 110, and the second lower roller guide shoe 820 is disposed at the end of the second column 220 near the car bottom 110. The first lower roller guide shoe 810 and the second lower roller guide shoe 820 are aligned and flush with the car bottom 110. By aligning the first lower roller guide shoe 810 and the second lower roller guide shoe 820 and making them flush with the car bottom 110, the stable operation of the car on the guide rail is ensured, while the required pit depth is reduced, thereby meeting the installation requirements of shallow pit elevators.

[0055] For example, such as Figure 1 , 2 As shown, both the first lower roller guide shoe 810 and the second lower roller guide shoe 820 are equipped with two rollers. This evenly distributes the force, improving the stability and durability of both rollers, reducing the load on individual rollers, and extending their service life. With both rollers simultaneously contacting the guide rail, the car can be guided more precisely along the rail, ensuring smooth and accurate elevator operation, reducing swaying and deviation, and improving passenger comfort. Furthermore, the two-roller design enhances safety; if one roller fails, the other roller can still provide support, ensuring the reliability and safety of elevator operation.

[0056] Understandably, referring to Figure 1 , 2 As shown in Figure 4, the upper roller guide shoe assembly 700 includes a first upper roller guide shoe 710 and a second upper roller guide shoe 720. The first upper roller guide shoe 710 is disposed at the end of the first column 210 near the car top assembly 500, and the second upper roller guide shoe 720 is disposed at the end of the second column 220 near the car top assembly 500. The first upper roller guide shoe 710 and the second upper roller guide shoe 720 are aligned. The alignment of the first upper roller guide shoe 710 and the second upper roller guide shoe 720 makes the car's guidance on the guide rail more stable, reducing swaying and deviation during operation. At the same time, it works in conjunction with the first lower roller guide shoe 810 and the second lower roller guide shoe 820 to improve the smoothness and comfort of elevator operation.

[0057] For example, such as Figure 1 , 2As shown in Figure 4, both the first upper roller guide shoe 710 and the second upper roller guide shoe 720 are equipped with two rollers. This evenly distributes the force, improving the stability and durability of both rollers, reducing the load on individual rollers, and extending their service life. With both rollers simultaneously contacting the guide rail, the car can be guided more precisely along the rail, ensuring smooth and accurate elevator operation, reducing swaying and deviation, and improving passenger comfort. Furthermore, the two-roller design enhances safety; if one roller fails, the other roller can still provide support, ensuring the reliability and safety of elevator operation.

[0058] Understandably, referring to Figure 1 , 2 As shown in Figure 4, the safety clamp assembly 900 includes a first safety clamp 910 and a second safety clamp 920. The first safety clamp 910 is disposed at the end of the first column 210 near the car top assembly 500 and below the first upper roller guide shoe 710. The second safety clamp 920 is disposed at the end of the second column 220 near the car top assembly 500 and below the second upper roller guide shoe 720. The first safety clamp 910 and the second safety clamp 920 are aligned. By aligning the first safety clamp 910 and the second safety clamp 920 and distributing them at the ends of the first column 210 and the second column 220 near the car top assembly 500, compared with the existing method of placing the safety clamps at the bottom, the pit depth requirement can be reduced, meeting the installation requirements of shallow pit elevators.

[0059] Understandably, referring to Figure 1 , 4 As shown, the fixed end of the lifting mechanism 101 is located on the side of the car top assembly 500 away from the car bottom 110. The lifting mechanism 101 has two drive ends, which are respectively connected to the first safety clamp 910 and the second safety clamp 920. The two drive ends are used to drive the first safety clamp 910 and the second safety clamp 920 to close simultaneously. By setting the fixed end of the lifting mechanism 101 on the side of the car top away from the car bottom 110 and using two drive ends to simultaneously connect the first safety clamp 910 and the second safety clamp 920, it is ensured that the safety clamps can close synchronously, thereby improving the response speed and reliability of emergency braking, ensuring smooth stopping of the car, and enhancing the safety and stability of elevator operation.

[0060] Understandably, referring to Figure 3 As shown, the car bottom assembly 100 also includes a buffer 120, which is disposed on the side of the car bottom 110 away from the car top assembly 500. Disposing the buffer 120 at the car bottom 110 allows for a cleaner elevator appearance compared to the existing placement at the elevator pit.

[0061] This application does not limit the number of buffers 120 in its embodiments; those skilled in the art can adjust them according to actual circumstances. For example, such as... Figure 3 As shown, taking the setting of two buffers 120 as an example. The two buffers 120 are respectively set on the side of the car bottom 110 away from the car bottom assembly 100. The two buffers 120 are aligned and can evenly distribute the impact force generated during the operation of the elevator, effectively slow down the falling speed of the car, and avoid damage to the elevator structure or passengers due to violent collisions.

[0062] Understandably, referring to Figure 1 As shown, the car also includes a guardrail assembly 102, which is located on the side of the car top assembly 500 away from the car bottom 110 and can protect the various components located on the car top assembly 500.

[0063] The elevator of the second aspect of this application includes the car of the first aspect of this application, which can improve the utilization rate of elevator shaft space and reduce the depth of elevator pit.

[0064] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
