[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] As described in the background section, traditional elevator car bottom designs typically employ a rigid structure. The rigidity of this structure causes impact forces to act directly on the elevator car and its passengers, thus affecting the comfort of the elevator ride.

[0028] To solve this technical problem, this utility model provides an elevator car bottom bracket.

[0029] For details, please refer to Figure 1-Figure 4 The elevator car bottom support specifically includes:

[0030] The buffer frame 1 includes a mounting plate 101 and a base frame 102 located below the mounting plate 101. Several buffer parts are connected between the base frame 102 and the mounting plate 101. Several support seats 109 are also provided on the side of the base frame 102 near the mounting plate 101. A spring steel ring 110 is fixedly installed on the top of the support seat 109.

[0031] The elevator car bottom bracket provided by this utility model has a buffer part set between the mounting plate 101 and the base frame 102. The buffer part can effectively absorb the impact energy when the elevator car hits the bottom, which significantly reduces the impact damage to the elevator car and passengers and improves the passenger riding experience. The support seat 109 and the spring steel ring 110 cooperate to limit the distance between the mounting plate 101 and the base frame 102, thereby reducing the situation where the buffer part is over-compressed and its service life is reduced. The setting of the spring steel ring 110 can also further play a buffering role.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] Example 1, please refer to Figure 1-Figure 4 An elevator car bottom support includes a buffer frame 1, which includes a mounting plate 101 and a base frame 102 located below the mounting plate 101. A plurality of buffer sections are connected between the base frame 102 and the mounting plate 101. A plurality of support seats 109 are also provided on the side of the base frame 102 near the mounting plate 101, and spring steel rings 110 are fixedly installed on the top of the support seats 109. This application, by providing buffer sections between the mounting plate 101 and the base frame 102, effectively absorbs the impact energy when the elevator car hits the bottom, significantly reducing impact damage to the elevator car and passengers, and improving the passenger riding experience.

[0036] The support base 109 and the spring steel ring 110 work together to limit the distance between the mounting plate 101 and the base frame 102, thereby reducing the possibility of the buffer being over-compressed and causing a decrease in its service life. The spring steel ring 110 can also further play a buffering role.

[0037] Furthermore, the buffer section includes a buffer component disposed between the mounting plate 101 and the base frame 102. The buffer component is configured to provide a stable physical basis for subsequent buffering actions, ensuring that the elevator car can be reliably protected when it hits the bottom.

[0038] Further, such as Figure 1-Figure 3 As shown, the buffer includes two first connecting shafts 103 respectively mounted on the mounting plate 101 and the base frame 102. A hydraulic buffer rod 104 is hinged between the two first connecting shafts 103. At the moment the car touches the bottom, the hydraulic buffer rod 104 can respond quickly and generate corresponding resistance according to the magnitude of the impact force, effectively converting the huge kinetic energy of the car when it touches the bottom into hydraulic energy and thermal energy, thus achieving efficient buffering. This buffering method has high buffering efficiency and stability, and can significantly reduce the impact force in a short time, protecting the car and passengers.

[0039] Furthermore, the buffer section also includes a limiting member, which is disposed between the mounting plate 101 and the base frame 102.

[0040] Further, such as Figure 1-Figure 3As shown, the limiting component includes a slide groove 105 formed on the mounting plate 101, a third connecting shaft 108 slidably connected in the slide groove 105, a second connecting shaft 106 mounted on the base frame 102, and a connecting frame 107 hinged between the third connecting shaft 108 and the second connecting shaft 106. The sliding connection between the slide groove 105 and the third connecting shaft 108 can precisely limit the movement trajectory of the connecting frame 107, making the shortest distance between the mounting plate 101 and the base frame 102 controllable, reducing the possibility of damage to components such as the hydraulic buffer rod 104 and the connecting frame 107 due to excessive descent of the mounting plate 101.

[0041] Example 2 further optimizes the elevator car bottom bracket provided in Example 1. Specifically, a number of connectors are connected to the mounting plate 101, which are used to connect the mounting plate 101 to the elevator car bottom.

[0042] Further, such as Figure 1-Figure 3 As shown, the connector includes a connecting bolt 111 that is inserted into the mounting plate 101. An elastic sleeve 112 is fitted on the outer surface of the connecting bolt 111. The elastic sleeve 112 is located on the top of the mounting plate 101. The elastic sleeve 112 can be made of rubber. The setting of the elastic sleeve 112 provides a buffer function between the mounting plate 101 and the bottom of the car.

[0043] Example 3 further optimizes the elevator car bottom bracket provided in Example 1 or 2, specifically, as follows: Figure 1 As shown, there are two buffer frames 1, and several connecting plates 2 are connected between the two buffer frames 1. The connecting plates 2 are used to connect the two buffer frames 1. The two buffer frames 1 are connected by the connecting plates 2 to form a whole, which can better withstand the weight and impact of the car.

[0044] Further, such as Figure 1 As shown, the end of the connecting plate 2 is fixedly connected to the base frame 102.

[0045] Furthermore, elastic buffer pads are provided at the bottom of both the connecting plate 2 and the base frame 102. The elastic buffer pads can be made of rubber. On the one hand, the elastic buffer pads can reduce the wear on the bottom of the connecting plate 2 and the base frame 102, and on the other hand, they can further improve the buffering effect.

[0046] The elevator car bottom bracket provided by this utility model is used as follows:

[0047] The present application is installed at the bottom of the car by nuts and connecting bolts 111. When the bottom is hit, the distance between the base frame 102 and the mounting plate 101 is shortened. The hydraulic buffer rod 104 is squeezed and generates force to achieve buffering between the mounting plate 101 and the base frame 102. The continuous descent of the mounting plate 101 is supported and limited by the spring steel ring 110 to reduce the possibility of damage to components such as the hydraulic buffer rod 104 and the connecting frame 107 due to excessive descent of the mounting plate 101. In addition, the spring steel ring 110 itself has the characteristic of elasticity and can play a buffering role when the mounting plate 101 comes into contact with the spring steel ring 110.
