TECHNICAL FIELD

[0001] The present application relates to the elevator technical field, and specifically to a household elevator without a trailing cable technology. BACKGROUND

[0002] The trailing cable is a kind of cable for elevators, which is mainly used to provide power and control signals to ensure that the elevator can operate safely and reliably. When installing, one end of the trailing cable is installed at the bottom of the elevator car and moves up and down with the elevator car, so the trailing cable occupies a large space and is easy to be worn out. In order to solve the above problems, the elevator without trailing cable technology is currently commonly used, among which, wireless charging technology is often used to complete in household elevators. However, it also has the following shortcomings:

[0003] 1. Low energy conversion efficiency. There is a certain energy loss in the transmission process, especially in the case of long distance and many obstacles, the energy loss will be more obvious.

[0004] 2. The charging speed is slower than wired charging. Since wireless charging needs to convert electrical energy into electromagnetic waves for transmission, and then the power supply device converts electromagnetic waves into electrical energy, which limits the charging speed.

[0005] 3. Sensitive to interference between chargers. If there are other wireless charging devices around the elevator, interference may occur, affecting the charging effect and speed.

[0006] 4. For high-power household elevators, wireless charging will generate a lot of heat, which may cause the temperature in the elevator car to rise, affecting the passenger experience;

DETAILED DESCRIPTION

[0046] Please refer to Figures 1-5 , in the embodiment of the present application, a household elevator without accompanying cable technology is provided, comprising:

[0047] Vertical rail 3 is arranged in elevator shaft 1;

[0048] Cage 2 can slide along vertical rail 3, and can be specifically configured with motor, reducer, traction rope, counterweight, speed limiter and safety clamp and other components to realize the up and down sliding action of cage 2. The motor is a driving component, the motor drives the traction wheel through the reducer to drive the traction rope and the cage 2 to run, and then performs vertical movement in the guide rail, while the counterweight acts on the traction rope to balance the weight of the elevator, the speed limiter and the safety clamp are important components to ensure the safety of the elevator operation, which will not be described here;

[0049] Three battery boxes 4 are arranged at the back of cage 2, and each battery box 4 can install battery 8, so as to supply power for the sliding of cage 2 through battery 8;

[0050] Three charging assemblies corresponding to battery boxes 4 are embedded into one side of elevator shaft 1; and

[0051] a controller, which is communicatively connected with the cage 2, the battery box 4 and the charging assembly, is configured to control the cage 2, the battery box 4 and the charging assembly, and to make that at any time, only one battery 8 is in the charging state, the other two batteries 8 are located in the battery box 4, and only one battery among the two batteries located in the battery box 4 is in the power supply state.

[0052] In the embodiment, by configuring the battery box 4 at the back of the cage 2, the battery 8 can be used to supply power for the sliding of the cage 2, and thus it is not necessary to configure a traveling power supply cable at the bottom of the cage 2. Of course, if the traveling cable-free technology is completely realized, a wireless communication module also needs to be configured to replace the traveling communication cable. In the embodiment of the application, it is mainly aimed at the traveling power supply cable part, and thus the traveling communication cable is not discussed.

[0053] In addition, in the embodiment, at any time, only one battery 8 is in the charging state, and the charging state means that the battery is located in the charging assembly.

[0054] The other two batteries 8 are located in the battery box 4, and only one battery among the two batteries located in the battery box 4 is in the power supply state, so as to ensure that there is sufficient battery replacement opportunity and the passenger's travel is not affected. The following further illustrates that the three batteries 8 can be a first battery, a second battery and a third battery, the three battery boxes 4 can be a first battery box, a second battery box and a third battery box, and the three charging assemblies can be a first charging assembly, a second charging assembly and a third charging assembly. Among them, the first battery is located in the first charging assembly, the second battery is located in the second battery box, the third battery is located in the third battery box, and the second battery is in the power supply state and the third battery is in the non-power supply state. When the second battery has a low power and needs to be charged, the third battery is converted to be in the power supply state, and the second battery is converted to be in the non-power supply state. Before the third battery finishes discharging, there is a long buffer time for finding an opportunity to send the first battery to the first battery box and the second battery to the charging assembly, and the passenger's travel is not affected.

[0055] In the embodiment, the number of the configured batteries, battery boxes and charging assemblies is relatively reasonable, which can provide a better power supply experience.

[0056] As a preferable embodiment, the three battery boxes 4 are vertically spaced, and each charging assembly corresponds to one battery box 4 when the cage 2 is at the lowest floor.

[0057] In the embodiment, the bottom of the battery 8 has a plug, and the charging assembly includes:

[0058] A horizontal groove is arranged on one side of the elevator shaft 1.

[0059] a horizontal rail 5 horizontally laid in the horizontal groove;

[0060] a track car 6 movably arranged on the horizontal rail 5, and a suction cup 7 arranged on the track car 6; and

[0061] a charging head arranged in the horizontal groove and corresponding to the battery 8.

[0062] In implementation, the position adjustment of the suction cup 7 can be realized by the movement of the track car 6 on the horizontal rail 5, the suction cup 7 can adsorb and position the battery in the battery box 4, the track car 6 can move the battery to the charging head position, and the battery can be charged or the fully charged battery can be sent to the battery box 4.

[0063] In the embodiment, the battery box 4 comprises:

[0064] a box body 41 fixed to the ladder box 2, and the box body 41 has an opening on the side away from the ladder box 2, and the bottom side of the box body 41 has an electrical connection socket corresponding to the battery 8;

[0065] two screw rod assemblies 42 symmetrically arranged in the box body 41, and the screw rod assembly 42 has a height adjustment end;

[0066] a positioning assembly 43 corresponding fixed to the height adjustment end, and the positioning assembly 43 has a power input end and a clamping end; and

[0067] a pre-positioning groove 44 connected between the power input ends of the two positioning assemblies 43, and when the battery 8 drives the pre-positioning groove 44 to move towards the direction close to the ladder box 2, the pre-positioning groove 44 can provide power to the power input end of the positioning assembly 43, so that the clamping end clamps the battery 8.

[0068] Similarly, when the battery 8 and the pre-positioning groove 44 move away from the ladder box 2, the pre-positioning groove 44 can provide power to the power input end of the positioning assembly 43, so that the clamping end releases the clamping of the battery 8;

[0069] The screw rod assembly 42 is a screw rod nut pair structure, which includes a screw rod, a motor, a nut and other components, wherein the nut is the height adjustment end of the screw rod assembly 42, and details are not repeated here. The screw rod assembly 42 can drive the two positioning assemblies 43 to adjust the height, so as to adjust the height of the battery 8, so that the plug contacts or does not contact the electrical connection socket, in other words, the battery 8 is in a power supply state or a non-power supply state.

[0070] In the implementation, the position adjustment of the suction cup 7 can be realized by the movement of the rail car 6 on the cross rail 5, the suction cup 7 can adsorb the battery in the battery box 4, the rail car 6 can drive the battery 8 and the pre-arrangement groove 44 to move away from the ladder box 2, at this time the pre-arrangement groove 44 can provide power for the power input end of the positioning assembly 43, so that the clamping end releases the clamping of the battery 8, or the position adjustment of the suction cup 7 can be realized by the movement of the rail car 6 on the cross rail 5, the rail car 6 can drive the battery 8 and the pre-arrangement groove 44 to move towards the ladder box 2, at this time the pre-arrangement groove 44 can provide power for the power input end of the positioning assembly 43, so that the clamping end clamps the battery 8.

[0071] Specifically, the positioning assembly 43 comprises:

[0072] a base 431 fixed to the height adjustment end of the lead screw assembly 42;

[0073] a first gear 434 rotatably arranged on the base 431, and one side of the pre-arrangement groove 44 has a first tooth 441 engaged with the first gear 434;

[0074] a driving wheel 435 coaxially fixed on the first gear 434;

[0075] a second gear 436 rotatably arranged in the box body 41, and a driven wheel is coaxially fixed on the second gear 436, and the driving wheel 435 and the driven wheel are connected through a synchronous belt transmission;

[0076] a driving arm 437 limitingly and slidably arranged in the box body 41, and the sliding direction of the driving arm 437 is perpendicular to the sliding direction of the pre-arrangement groove 44, and the driving arm 437 is provided with a second tooth engaged with the second gear 436.

[0077] As a preferred embodiment, the side of the driving arm 437 close to the battery 8 is fixed with a positioning wedge 438, and the battery 8 is provided with a wedge surface 81 corresponding to the positioning wedge 438.

[0078] As a preferred embodiment, one side of the base 431 is connected with a connecting seat 433 through a first spring 432, and the connecting seat 433 is connected with the pre-arrangement groove 44 to provide reset for the pre-arrangement groove 44.

[0079] It should be understood that in the final stage of positioning the battery by using the positioning assembly, the greater the extrusion force between the positioning wedge 438 and the wedge surface 81, the more difficult the battery is to move towards the direction of the ladder box 2. In order to solve this problem, in the embodiment, the driving arm 437 is divided into two sections, and a resilient pad 4314 is connected between the two sections. The resilient pad 4314 is located between the second tooth and the ratchet 4310 closest to the second tooth.

[0080] The end of the driving arm 437 close to the battery 8 is formed with a ratchet 4310 and a groove 4311 which are continuously distributed in sequence;

[0081] The outer spacer sleeve of the driving arm 437 is provided with a ring seat 439 which is fixed in the box body 41. The ring seat 439 is hingedly connected with a pawl 4312. The middle part of the pawl 4312 is connected with the ring seat 439 by using a second spring 4313.

[0082] Therefore, in the implementation, the position adjustment of the suction cup 7 can be realized by the movement of the rail car 6 on the cross rail 5. The rail car 6 can drive the battery 8 and the pre-container groove 44 to move towards the direction of the ladder box 2. At this time, the first tooth 441 on one side of the pre-container groove 44 is engaged with the first gear 434, thereby driving the first gear 434 to rotate. The driving arm 437 is also moved because the second tooth is arranged on the driving arm 437. When the driving arm 437 moves towards the battery, the following situation will occur:

[0083] Firstly, the driving arm 437 is divided into two sections, and a resilient pad 4314 is connected between the two sections. The resilient pad 4314 is located between the second tooth and the ratchet 4310 closest to the second tooth. The two sections of the driving arm are respectively a first arm body and a second arm body. The second tooth is distributed on the first arm body, and the ratchet and the groove are distributed on the second arm body.

[0084] Since the middle part of the pawl 4312 is connected with the ring seat 439 by the second spring 4313, the pawl can extend into the groove 4311, thus the second spring can provide a certain abutting force for the pawl 4312, the abutting force can act on the groove, thus hindering the second arm body from moving towards the battery direction, while the first arm body can continue to move towards the battery direction, thus the elastic pad 4314 is compressed at this time, until the compression limit is reached, the second arm body is out of the abutting limit of the pawl, and moves towards the battery direction, in short, the movement of the positioning wedge block 438 is not continuous, and can be regarded as intermittent movement, in other words, the movement of the positioning wedge block 428 lags behind the movement of the battery;

[0085] In the last stage of locking of the positioning wedge block and the wedge surface (when the positioning wedge block and the wedge surface have not contacted), when the battery moves towards the direction of the ladder box 2, the positioning wedge block 438 remains stationary until the elastic pad 4314 is compressed to the compression limit, at this time the battery has reached the specified position, the second arm body is out of the abutting limit of the pawl, and moves towards the battery direction, so that the positioning wedge block and the wedge surface remain in contact and locked.

[0086] In order to facilitate the reset of the pawl, a first magnetic block is embedded on the pawl, a second magnetic block 4315 capable of magnetically attracting the first magnetic block is embedded in the ring seat 439, and the second magnetic block is an electromagnetic block.

[0087] When the second magnetic block is powered, the second magnetic block can magnetically attract the first magnetic block, so that the pawl is deflected to contact the locking of the driving arm 437, and then under the action of the first spring 431, the pre-provisioning groove 44 can be reset.

[0088] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
