Description

Technical Field

[0001] This invention relates to the field of villa elevator technology, specifically to an elevator that can increase load capacity and facilitate escape. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical. Most villas are equipped with villa elevators during the design and construction process to facilitate residents going up and down the stairs. Villa elevators are divided into two types according to their usage scenarios: outdoor elevators and indoor elevators.

[0003] For example, patent application CN201810890502.4 discloses a villa elevator. When cleaning the inner wall of the car, the cleaning fluid and cleaning water slide down the inner side wall of the car. Because the water collection device embedded in the car has an inlet for collecting the cleaning fluid, the cleaning fluid flows into the interior of the water collection device through the inlet, reducing the damage of the cleaning fluid to the car. At the same time, the resistance sheet embedded in the car increases the temperature inside the car and accelerates the vaporization of the cleaning fluid inside the car. The ventilation pipe opened on the top of the car can increase the air inside the car and accelerate the evaporation and circulation of moisture inside the car.

[0004] For example, patent application number CN200810029275.2 discloses a new type of outdoor villa elevator. The new type of outdoor villa elevator provided by this technical solution has a lighting system in the car powered by a battery installed in the car, which is not affected by power outages and will not cause damage to the power supply system during elevator operation. It is also very convenient to use. In addition, the present invention uses a safe voltage, which is safe. Since the present elevator does not require wires, it is aesthetically pleasing.

[0005] However, as mentioned above, villa elevators cannot expand their carrying capacity during use, making it inconvenient to move large objects. Furthermore, when people are inside the elevator, if they encounter danger at a high place, it is difficult for them to escape quickly, which can lead to injury.

[0006] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed an elevator that can increase its load-bearing capacity and facilitate escape. Summary of the Invention

[0007] The purpose of this invention is to provide an elevator that can increase its carrying capacity and facilitate escape, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an elevator that can increase load capacity and facilitate escape, comprising a chassis and an expansion assembly. Four supports are symmetrically and fixedly connected to the left and right sides of the chassis, and a top plate is fixedly connected to the upper end of each support. A car is slidably connected between the supports via rollers, and pulleys are symmetrically and rotatably connected to the front and rear sides of the upper surface of the car. Traction belts are symmetrically and fixedly connected to the left and right sides of the rear part of the top plate, and a dual-axis motor is fixedly connected to the center of the top plate. Winding wheels are symmetrically and fixedly connected to the left and right sides of the dual-axis motor. The expansion assembly is symmetrically arranged on the left and right sides of the car, and a protective assembly is provided on the side of the expansion assembly located inside the car. An air pump is fixedly connected to the bottom of the car, and guide rails are symmetrically provided on the upper and lower sides of the inner wall of the car. Support assemblies are symmetrically arranged on the left and right sides of the car.

[0009] Furthermore, the expansion assembly includes an upper partition, a lower partition, a panel, and locking holes. The upper partition is symmetrically and rotatably connected to the left and right sides of the upper end of the car, and the lower partition is symmetrically and rotatably connected to the left and right sides of the lower end of the car. The lower end of the upper partition is fixedly connected to the panel, and locking holes are provided on the surfaces of the upper and lower partitions and the inner wall of the car. The upper and lower partitions are interlocked by the panel, and the lower end of the lower partition is provided with an inclined surface.

[0010] Furthermore, the expansion assembly also includes a sealing plate, an inflatable slide, an air chamber, a top spring, and a shaft. The sealing plates are symmetrically arranged on the left and right sides of the car, and an inflatable slide is fixedly connected to the middle of the sealing plate. Air chambers are symmetrically arranged on the front and rear sides of the inflatable slide, and a top spring is fixedly connected to the air chamber. A shaft is fixedly connected to the other end of the top spring.

[0011] Furthermore, the sealing plate is rotatably connected to the car via a shaft, and the shaft is H-shaped. The shaft is elastically connected to the air chamber via a top spring, and the air pump is connected to the inflation slide via the shaft.

[0012] Furthermore, the expansion assembly also includes a card cavity, a card slot, a card spring, a card rod, and a card block. The sealing plate has card cavities symmetrically opened on the upper and lower sides, and a card slot is opened on the side of the card cavity away from the upper partition and on the side of the lower partition. A card spring is fixedly connected in the card cavity, and a card rod is fixedly connected to the other end of the card spring. A card block is fixedly connected to the side of the card rod near the card slot.

[0013] Furthermore, the protective assembly includes a cavity, a spring, a rod, a protective plate, and a socket. The sealing plate has a cavity on the side away from the upper and lower partitions, and a spring is fixedly connected inside the cavity. The other end of the spring is fixedly connected to a rod. The sealing plate is symmetrically rotatably connected to the front and rear sides, and the protective plate has a socket on its surface.

[0014] Furthermore, the protective assembly also includes a sliding cavity, a sliding groove, a compression spring, a sliding rod, and a slider. The upper and lower sides of the protective plate are symmetrically provided with sliding cavities, and a sliding groove is provided on the side of the sliding cavity near the sealing plate. A compression spring is fixedly connected inside the sliding cavity, and a sliding rod is fixedly connected to the other end of the compression spring. A slider is fixedly connected to the side of the sliding rod near the sliding groove.

[0015] Furthermore, the slide rod is slidably connected to the car via a guide rail, and the slide rod is elastically connected to the slide cavity via a compression spring. The insertion rod is engaged with the guard plate via an insertion hole, and the slider is slidably connected to the guard plate via a slide groove.

[0016] Furthermore, the support assembly includes a storage cavity, a tension spring, a groove, a support plate, a lever, and a pad. The left and right sides of the car are symmetrically provided with storage cavities, and tension springs are fixedly connected inside the storage cavities. A groove is provided above the storage cavity. The other end of the tension spring is fixedly connected to the support plate, and a lever is fixedly connected above the support plate. A pad is provided on one side of the lever, and the pad engages with the groove through the lever.

[0017] Furthermore, the method of using the elevator, which can increase carrying capacity and facilitate escape, includes the following steps:

[0018] S1: During normal use, the dual-shaft motor drives the winding wheel to rotate, thereby winding and unwinding the traction belt. This, in turn, drives the car to move between the supports via pulleys. The supports can restrict the car via rollers to prevent the car from tilting during movement.

[0019] S2: When expanding the carrying space, first slide the lever in the slot to move the support plate out of the storage cavity and insert the pad into the slot. Then press the insert rod into the cavity and rotate the guard plate on the sealing plate. Then pull the locking rod out of the locking hole and slide the shaft into the air cavity to push the sealing plate outward for expansion. After expansion, the guard plate can seal the front and rear sides of the sealing plate to keep the car sealed. When the lower partition is rotated to the horizontal state, the support plate can provide support for the lower partition.

[0020] S3: When a person is inside the elevator and encounters danger at a high position, pull the pad out of the slot. The support plate will then quickly rebound into the storage cavity under the action of the tension spring. Rotate the guard plate on the sealing plate until they are perpendicular to each other, and put the slide rod and the locking rod into the slide cavity and locking cavity respectively. Push the upper part of the sealing plate so that the sealing plate rotates in the car through the shaft, causing the sealing plate to tilt. At the same time, the air pump quickly inflates the air slide, causing it to expand and pop out from the sealing plate. At this time, the passenger can leave the car and quickly slide to the ground through the sealing plate and the air slide, escaping danger and quickly escaping.

[0021] This invention provides an elevator with increased load-bearing capacity for easier escape, which has the following advantages: the load-bearing space of the elevator can be expanded during use, allowing the elevator to transport larger objects, while maintaining the airtightness of the elevator after expanding the load-bearing space, thus ensuring passenger safety. When a person is inside the elevator and encounters danger at a height, the elevator can be deformed, allowing passengers to escape quickly and avoid injury.

[0022] 1. In normal use, the locking rod can be inserted into the locking hole of the car under the action of the locking spring, thereby fixing the sealing plate to the left and right ends of the car. At this time, the upper partition and the lower partition are locked together by the insert plate, thereby blocking the sealing plate. When the car needs to be expanded, the locking block can be slid in the locking groove to pull the locking rod out of the locking hole. At the same time, the shaft is slid into the air chamber and the top spring is compressed to push the sealing plate outward, thereby releasing the locking between the upper partition and the lower partition and causing the upper partition and the lower partition to rotate on the car. When the sealing plate moves to the edge of the upper partition and the lower partition, the locking rod can rebound under the action of the locking spring (912) and insert into the locking hole to fix the sealing plate, thereby sealing the left and right sides.

[0023] 2. Before expanding the carrying space, the present invention first presses the insertion rod through the insertion hole to press the insertion rod into the cavity and compress the spring. Then, the guard plate is rotated on the sealing plate. The sliding rod can be inserted into the guide rail under the action of the compression spring to restrict the movement trajectory of the guard plate. When pushing the sealing plate, the sliding rod can limit the movement distance of the sealing plate through the guide rail to prevent the sealing plate from moving too much and falling out between the upper and lower partitions. After the expansion is completed, the guard plate can seal the front and rear sides of the sealing plate to keep the car sealed, thereby protecting the passengers and ensuring their safety.

[0024] 3. When expanding the load-bearing space, this invention first slides the lever block in the lever groove to move the support plate out of the storage cavity and stretch the tension spring. Then, the pad block is inserted into the lever groove, and the pad block can restrict the lever block through the lever groove, thereby restricting the support plate. This allows the support plate to provide support for the lower partition when it rotates to a horizontal state, preventing the lower partition from continuing to rotate downwards and causing the area below the sealing plate to become suspended. At the same time, it also ensures that the lower partition can provide stable support for passengers or items. When a person is inside the elevator and encounters danger at a height, the pad block can be pulled out of the lever groove, and the support plate can quickly rebound into the storage cavity under the action of the tension spring. After rotating the guard plate on the sealing plate until they are perpendicular to each other, the slider and the locking block slide in the sliding groove and the locking groove respectively, and the sliding rod and the locking rod are respectively put into the sliding cavity and the locking cavity. At this time, the shaft rod is connected to the car under the action of the top spring. When the upper part of the sealing plate is engaged, pushing it allows the sealing plate to rotate within the car via a shaft. This simultaneously releases the engagement between the upper and lower partitions, causing them to rotate within the car. Under gravity, the lower partition rotates until its lower end is flush with the car. Once the sealing plate is flush with the lower partition, the lower partition provides support, keeping the sealing plate tilted. At the same time, the air pump rapidly inflates the inflation slide via the shaft, causing it to expand and eject from the sealing plate. Passengers can then leave the car and slide quickly to the ground via the sealing plate and inflation slide, escaping danger and escaping quickly. During escape, the upper partition provides protection by shielding the area above the sealing plate, while the guard plate, restrained by the insert rod, remains perpendicular to the sealing plate, thus limiting passenger movement and preventing them from falling and getting injured from the front or back of the sealing plate while sliding.

The expansion assembly 9 also includes a sealing plate 905, an inflatable slide 906, an air chamber 907, a top spring 908, and a shaft 909.

A shaft 909 is fixedly connected to the other end of the top spring 908. The sealing plate 905 is rotatably connected to the car 4 via the shaft 909, which is H-shaped. The shaft 909 is elastically connected to the air chamber 907 via the top spring 908. The air pump 11 is connected to the inflatable slide 906 via the shaft 909. The expansion assembly 9 also includes a locking cavity 910, a locking slot 911, a locking spring 912, a locking rod 913, and a locking block 914. Locking cavities 910 are symmetrically opened on the upper and lower sides of the sealing plate 905. A locking slot 911 is opened on the side of the locking cavity 910 away from the upper partition 901 and lower partition 902. A retaining ring 912 is fixedly connected inside cavity 910, and a retaining rod 913 is fixedly connected to the other end of the retaining ring 912. A retaining block 914 is fixedly connected to the side of the retaining rod 913 near the retaining groove 911. The protective assembly 10 includes a cavity 1001, a spring 1002, a insert rod 1003, a protective plate 1004, and an insertion hole 1005. A cavity 1001 is formed on the side of the sealing plate 905 away from the upper partition 901 and the lower partition 902, and a spring 1002 is fixedly connected inside the cavity 1001. The insert rod 1003 is fixedly connected to the other end of the spring 1002. Protective plates 1004 are symmetrically rotatably connected to the front and rear sides of the sealing plate 905, and insertion holes 1005 are formed on the surface of the protective plates 1004. The protective assembly 10 also includes a sliding cavity 1006 and a sliding groove 100. 7. Compression spring 1008, slide rod 1009 and slider 1010. The upper and lower sides of the guard plate 1004 are symmetrically provided with slide cavities 1006, and the slide cavity 1006 is provided with a slide groove 1007 on the side near the sealing plate 905. The compression spring 1008 is fixedly connected in the slide cavity 1006, and the other end of the compression spring 1008 is fixedly connected with the slide rod 1009. The slider 1010 is fixedly connected on the side of the slide rod 1009 near the slide groove 1007. The slide rod 1009 is slidably connected to the car 4 through the guide rail 12, and the slide rod 1009 is elastically connected to the slide cavity 1006 through the compression spring 1008. The insertion rod 1003 is engaged with the guard plate 1004 through the insertion hole 1005, and the slider 1010 is slidably connected to the guard plate 1004 through the slide groove 1007.

[0035] The specific operation is as follows: During normal use, the locking rod 913 can be engaged in the locking hole 904 of the car 4 under the action of the retaining spring 912, thereby fixing the sealing plate 905 to the left and right ends of the car 4. At this time, the upper partition 901 and the lower partition 902 are engaged with each other through the insert plate 903, thereby blocking the sealing plate 905. When it is necessary to expand the car 4, the locking block 914 is slid in the locking groove 911, and the locking rod 913 can be pulled out from the locking hole 904. At the same time, the shaft 909 is slid into the air chamber 907 and the top spring 908 is compressed, pushing the sealing plate 905 outward, thereby releasing the engagement between the upper partition 901 and the lower partition 902, and causing the upper partition 901 and the lower partition 902 to rotate on the car 4. When the sealing plate 905 moves to the edge of the upper partition 901 and the lower partition 902, the locking rod 913 can be engaged under the action of the retaining spring 912. The spring returns and inserts into the locking hole 904 to fix the sealing plate 905, thereby sealing the left and right sides. Before expanding the load-bearing space, the insert rod 1003 is pressed through the insertion hole 1005 to press the insert rod 1003 into the cavity 1001 and compress the spring 1002. Then, the guard plate 1004 is rotated on the sealing plate 905. The slide rod 1009 can be inserted into the guide rail 12 under the action of the compression spring 1008 to limit the movement trajectory of the guard plate 1004. When pushing the sealing plate 905, the slide rod 1009 can limit the movement distance of the sealing plate 905 through the guide rail 12 to prevent the sealing plate 905 from moving too much and coming out between the upper partition 901 and the lower partition 902. After the expansion is completed, the guard plate 1004 can seal the front and rear sides of the sealing plate 905, keeping the car 4 sealed, thereby protecting the passengers and ensuring their safety.

[0036] Please see Figure 1 , Figures 3 to 4 and Figures 6 to 7 The support assembly 13 includes a storage cavity 1301, a tension spring 1302, a groove 1303, a support plate 1304, a lever 1305, and a pad 1306. The car 4 has symmetrical storage cavities 1301 on its left and right sides, and a tension spring 1302 is fixedly connected inside the storage cavity 1301. A groove 1303 is provided above the storage cavity 1301. The other end of the tension spring 1302 is fixedly connected to the support plate 1304, and a lever 1305 is fixedly connected above the support plate 1304. A pad 1306 is provided on one side of the lever 1305, and the pad 1306 is engaged with the groove 1303 through the lever 1305.

[0037] The specific operation is as follows: When expanding the bearing space, first slide the lever 1305 within the lever groove 1303 to move the support plate 1304 out of the receiving cavity 1301 and stretch the tension spring 1302. Then, insert the pad 1306 into the lever groove 1303. The pad 1306 can then restrict the lever 1305 through the lever groove 1303, thereby restricting the support plate 1304. This allows the support plate 1304 to provide support for the lower partition 902 when it rotates to a horizontal position, preventing the lower partition 902 from continuing to rotate downwards and causing the sealing plate 905 to become suspended. Simultaneously, it ensures that the lower partition 902 provides stable support for passengers or items. When a person is inside the elevator and encounters danger at a height, the pad 1306 can be pulled out from the slot 1303, and the support plate 1304 can quickly rebound into the storage cavity 1301 under the action of the tension spring 1302. After rotating the guard plate 1004 on the sealing plate 905 until they are perpendicular to each other, the slider 1010 and the locking block 914 slide in the slide groove 1007 and the locking slot 911 respectively, and the slide rod 1009 and the locking rod 913 are respectively put into the slide cavity 1006 and the locking cavity 910. At this time, the shaft 909 engages with the car 4 under the action of the top spring 908. Pushing the upper part of the sealing plate 905 allows the sealing plate 905 to rotate inside the car 4 via the shaft 909. Simultaneously, it releases the engagement between the upper partition 901 and the lower partition 902, causing the upper partition 901 and the lower partition 902 to rotate on the car 4. Under the action of gravity, the lower partition 902 rotates until its lower end is in contact with the car 4. After the sealing plate 905 rotates to be in contact with the lower partition 902, the lower partition 902 can provide support for the sealing plate 905, keeping the sealing plate 905 in an inclined state. The air pump 11 rapidly inflates the air slide 906 via the shaft 909, causing it to expand and pop out from the sealing plate 905. Passengers can then leave the car 4 and quickly slide to the ground via the sealing plate 905 and the air slide 906 to escape danger and make a quick escape. During the escape, the upper partition 901 can provide protection by blocking the area above the sealing plate 905, while the guard plate 1004 remains perpendicular to the sealing plate 905 under the restriction of the insert rod 1003, thereby restricting passengers and preventing them from falling from the front and rear sides of the sealing plate 905 and getting injured when sliding on it.

[0038] In summary, this elevator, which increases load capacity and facilitates escape, operates by using a dual-axis motor 7 to drive a winding wheel 8, thereby winding and unwinding the traction belt 6. This, in turn, moves the car 4 between supports 2 via pulleys 5. Supports 2 use rollers to restrain the car 4, preventing it from tilting during movement. During normal use, the locking lever 913, under the action of the locking spring 912, engages with the locking hole 904 in the car 4, fixing the sealing plate 905 to both ends of the car 4. At this time, the upper partition 901 and lower partition 902 are interlocked by the insert plate 903, thus shielding the sealing plate 905. When the load-bearing space needs to be expanded, the sliding block 1305 is first slid within the slot 1303 to move the support plate 1304 out of the storage cavity 1301. Stretch the tension spring 1302, then insert the pad 1306 into the slot 1303. The pad 1306 can then restrict the lever 1305 through the slot 1303, thereby restricting the support plate 1304. Then, press the insert rod 1003 through the insertion hole 1005, pressing the insert rod 1003 into the cavity 1001 and compressing the spring 1002. Then, rotate the guard plate 1004 on the sealing plate 905. The slide rod 1009 can be inserted into the guide rail 12 under the action of the compression spring 1008, restricting the movement trajectory of the guard plate 1004. Slide the locking block 914 in the slot 911 to pull the locking rod 913 out of the locking hole 904. At the same time, slide the shaft 909 into the air cavity 907 and compress the top spring 908, pushing the sealing plate 905 outward to release the tension. In addition to the engagement between the upper partition 901 and the lower partition 902, which causes the upper partition 901 and the lower partition 902 to rotate on the car 4, when the sealing plate 905 moves to the edge of the upper partition 901 and the lower partition 902, the locking rod 913 can spring back under the action of the locking spring 912 and insert into the locking hole 904 to fix the sealing plate 905, thereby sealing the left and right sides. When pushing the sealing plate 905, the sliding rod 1009 can limit the movement distance of the sealing plate 905 through the guide rail 12 to prevent the sealing plate 905 from moving too much and coming out between the upper partition 901 and the lower partition 902. After the expansion is completed, the guard plate 1004 can seal the front and rear sides of the sealing plate 905, keeping the car 4 sealed, thereby protecting the passengers and ensuring their safety. When the lower partition 902 rotates to a horizontal position, the support plate 1304 provides support for the lower partition 902, preventing it from continuing to rotate downwards and causing the area below the sealing plate 905 to become suspended. This also ensures that the lower partition 902 provides stable support for passengers or items. When a person is inside the elevator and encounters danger at a height, the pad 1306 can be pulled out of the slot 1303. The support plate 1304 will then quickly spring back into the storage cavity 1301 under the action of the tension spring 1302. After rotating the guard plate 1004 on the sealing plate 905 until they are perpendicular to each other, the slider 1010 and the locking block 914 slide in the slide groove 1007 and the locking slot 911 respectively, and the slide rod 1009 and the locking rod 913 are then retracted into the slide cavity 1006 and the locking cavity 910 respectively.At this time, the shaft 909 engages with the car 4 under the action of the top spring 908. Pushing the upper part of the sealing plate 905 allows the sealing plate 905 to rotate inside the car 4 via the shaft 909. Simultaneously, it releases the engagement between the upper partition 901 and the lower partition 902, causing the upper partition 901 and the lower partition 902 to rotate on the car 4. Under the action of gravity, the lower partition 902 rotates until its lower end is in contact with the car 4. After the sealing plate 905 rotates to be in contact with the lower partition 902, the lower partition 902 can provide support for the sealing plate 905, keeping the sealing plate 905 in an inclined state. Air pump 11 rapidly inflates the air slide 906 via shaft 909, causing it to expand and pop out from the sealing plate 905. Passengers can then leave the car 4 and quickly slide to the ground via the sealing plate 905 and air slide 906, escaping danger and escaping quickly. During escape, the upper partition 901 provides protection above the sealing plate 905, while the guard plate 1004, restrained by the insert rod 1003, remains perpendicular to the sealing plate 905, thus restricting passengers and preventing them from falling and getting injured from the front or rear sides of the sealing plate 905 while sliding on it.

2. An elevator according to claim 1, characterized in that, can increase load capacity and facilitate escape, The method of using this elevator, which increases its carrying capacity and facilitates escape, includes the following steps: S1: During normal use, the dual-shaft motor (7) drives the winding wheel (8) to rotate, thereby winding and unwinding the traction belt (6), and then driving the car (4) to move between the brackets (2) through the pulleys (5). The brackets (2) can restrict the car (4) through the rollers to prevent the car (4) from tilting when moving. S2: When expanding the carrying space, first slide the lever (1305) in the lever groove (1303), move the support plate (1304) out of the storage cavity (1301) and insert the pad (1306) into the lever groove (1303), then press the insert rod (1003) into the cavity (1001) and rotate the guard plate (1004) on the sealing plate (905), then pull out the locking rod (913) from the locking hole (904), and at the same time slide the shaft rod (909) into the air cavity (907), push the sealing plate (905) outward to expand. After the expansion is completed, the guard plate (1004) can seal the front and rear sides of the sealing plate (905) to keep the car (4) sealed. When the lower partition (902) is rotated to the horizontal state, the support plate (1304) can provide support for the lower partition (902). S3: When a person is inside the elevator and encounters danger at a height, pull the pad (1306) out of the slot (1303). The support plate (1304) will then quickly spring back into the storage cavity (1301) under the action of the tension spring (1302). Rotate the guard plate (1004) on the sealing plate (905) until they are perpendicular to each other, and put the slide rod (1009) and the locking rod (913) into the slide cavity (1006) and the locking cavity (913) respectively. 10) Push the upper part of the sealing plate (905) so that the sealing plate (905) rotates in the car (4) through the shaft (909), causing the sealing plate (905) to tilt. At the same time, the air pump (11) quickly inflates the air slide (906), causing it to expand and pop out from the sealing plate (905). At this time, the passenger can leave the car (4) and slide quickly to the ground through the sealing plate (905) and the air slide (906), escape danger, and escape quickly.
