Figure 3 This is a schematic diagram of an elevator car toe guard structure installed to the bottom of the car and in a folded state according to an implementation scheme of the utility model.
[0053] like Figures 1 to 3 As shown, the toe guard structure of an elevator car according to the embodiment of the present invention comprises: a mounting bracket 200 , a toe guard 300 , a track 400 , a sliding member 500 , a support rod 600 and a control assembly 700 .
[0054] The mounting bracket 200 is mounted to the bottom of the car 100 near the side of the car door. Specifically, in the exemplary embodiment of the present utility model, the bottom of the car 100 near the side of the car door is provided with an extension plate 110 extending downward. The mounting bracket 200 includes a first mounting bracket 210 and a second mounting bracket 220. The upper portions of the first mounting bracket 210 and the second mounting bracket 220 are respectively connected to the bottom of the car and are respectively located on both sides of the extension plate 110. The lower portions of the first mounting bracket 210 and the second mounting bracket 220 are respectively provided with shaft holes (not shown in the figure).
[0055] The foot guard 300 can be rotatably mounted to the mounting bracket 200. Specifically, the foot guard 300 includes a plate body 310, a first connecting plate 320, a second connecting plate 330 and a rotating shaft 340. The first connecting plate 320 and the second connecting plate 330 are respectively bent from both sides of the plate body 310 to the back of the plate body 310 to form a structure substantially perpendicular to the plate body 310. Both ends of the rotating shaft 340 are respectively fixedly connected to the first connecting plate 320 and the second connecting plate 330 and are respectively inserted into the shaft holes at the lower parts of the first mounting bracket 210 and the second mounting bracket 220. The rotating shaft 340 can rotate in the shaft hole so that the foot guard 300 can be rotatably mounted to the mounting bracket 200. Further, both ends of the rotating shaft 340 can be connected to the first connecting plate 320 and the second connecting plate 330 by welding, or can be connected to the first connecting plate 320 and the second connecting plate 330 by other methods, which can be any connection method in the prior art as long as the above functions can be achieved.
[0056] Furthermore, if Figure 3 As shown, the foot guard 300 further includes a reinforcing rib 350. The reinforcing rib 350 is disposed in the middle of the back of the board body 310 and extends along the length direction of the board body 310. The reinforcing rib 350 is used to enhance the strength of the foot guard 300. In the exemplary embodiment of the utility model, the number of the reinforcing rib 350 is set to 1, and as an option, the number of the reinforcing rib 350 can also be set to more, which can be adjusted according to actual conditions.
[0057] The track 400 is disposed at the bottom of the car 100. Specifically, the track 400 includes a first track 410 and a second track 420. The first track 410 and the second track 420 are disposed opposite to each other, and the first track 410 is provided with a first receiving portion 411, and the second track 420 is provided with a second receiving portion 421.
[0058] The sliding member 500 is slidably disposed on the track 400. Specifically, Figure 4 and Figure 5As shown, the sliding member 500 includes a first slider 510 and a second slider 520. The first slider 510 is set to a square structure and is located in the first receiving portion 411 of the first track 410. The first slider 510 can slide in the first receiving portion 411 of the first track 410. The cross section of the first receiving portion 411 corresponds to that the first slider 510 can be set to a square shape, thereby limiting the rotation of the first slider 510 when sliding in the first receiving portion 411. The second slider 520 is located in the second receiving portion 421 of the second track 420. The second slider 520 can slide in the second receiving portion 421 of the second track 420.
[0059] One end of the support rod 600 is hinged to the foot guard 300, and the other end of the support rod 600 is hinged to the sliding member 500. Specifically, the support rod 600 includes a first support rod 610 corresponding to the first slider 510 and a second support rod 620 corresponding to the second slider 520. One end of the first support rod 610 is hinged to the middle of the first connecting plate 320 of the foot guard 300, and the other end of the first support rod 610 is hinged to the first slider 510. One end of the second support rod 620 is hinged to the middle of the second connecting plate 330 of the foot guard 300, and the other end of the second support rod 620 is hinged to the second slider 520.
[0060] Further, in an exemplary embodiment of the present utility model, with Figure 5 As shown, bearings 611 are respectively provided at the positions where the first support rod 610 is hinged to the first slider 510 and the first connecting plate 320, and bearings 611 are also provided at the positions where the second support rod 620 is hinged to the second slider 520 and the second connecting plate 330, so as to reduce the friction resistance of the first support rod 610 and the second support rod 620 during the rotation process, thereby improving the durability and user experience of the toe guard structure of the utility model.
[0061] The control assembly 700 is arranged at the bottom of the car 100 and can control the sliding of the sliding member 500 to control the rotation of the support rod 600 to drive the footboard 300, and when the sliding member 500 slides to one end of the track 400, the support rod 600 drives the footboard 300 to rotate to the unfolded state, and when the sliding member 500 slides to the other end of the track 400, the support rod 600 drives the footboard 300 to rotate to the folded state. Specifically, the sliding member 500 is provided with a threaded hole (not shown in the figure), and the control assembly includes a motor 710 and a lead screw 720. The motor 710 has an output shaft 711. The motor 710 can be electrically connected to the elevator control system and control the rotation of the output shaft 711 according to the electrical signal of the elevator control system. One end of the lead screw 720 is fixedly connected to the output shaft 711, so that when the output shaft 711 of the motor 710 rotates, the lead screw 720 rotates accordingly. The other end of the lead screw 720 passes through the threaded hole of the sliding member 500, so that the sliding member 500 is connected to the lead screw 720 through the threaded hole, and the threaded hole cooperates with the lead screw 720, so that the sliding member 500 can slide when the lead screw 720 rotates. By controlling the rotation of the lead screw 720, the sliding of the sliding member 500 can be controlled, thereby controlling the support rod 600 to drive the rotation of the foot guard 300, so that the foot guard 300 rotates to the unfolded state or the folded state.
[0062] When the foot guard 300 is rotated to the unfolded state, the board body 310 is basically in a vertical state and is roughly flush with one side of the car door 100. When the foot guard 300 is rotated to the folded state, the board body 310 is basically in a horizontal state and close to the bottom plate of the car 100.
[0063] Further, with Figure 5 and Figure 6As shown, the motor 710 is arranged at the bottom of the car 100 corresponding to the first track 410, and the lead screw 720 is arranged at the first accommodating portion 411 of the first track 410 corresponding to the motor 710 and the first slider 510. The threaded hole is arranged in the first slider 510. The control assembly 700 further includes a slide bar 730. The slide bar 730 is fixed to the second accommodating portion 421. The second slider 520 is connected to the slide bar 730. The second slider 520 can slide along the slide bar 730 and slide along the second track 420 at the same time. When the output shaft 711 of the motor 710 rotates along the first rotation direction, the lead screw 720 rotates along the first rotation direction and causes the first slider 510 to slide in the first sliding direction. The first slider 510 drives the first support rod 610 to generate a first motion, thereby driving the foot guard 300 to rotate in the unfolding direction. The rotation of the foot guard 300 can drive the second support rod 620 to generate a second motion, so that the second slider 520 slides along the second track 420 together with the first slider 510 in the first sliding direction. When the output shaft 711 of the motor 710 rotates in the second rotation direction, the lead screw 720 rotates in the second rotation direction and causes the first slider 510 to slide in the second sliding direction. The first slider 510 drives the first support rod 610 to produce a third action, thereby driving the foot guard 300 to rotate in the folding direction. The rotation of the foot guard 300 can drive the second support rod 620 to produce a fourth action, so that the second slider 520 slides along the second track 420 together with the first slider 510 in the second sliding direction.
[0064] Furthermore, the lead screw 720 can be self-locking, that is, the thread lead angle of the lead screw 720 is smaller than its equivalent friction angle, so that when the lead screw 720 stops rotating, the first slider 510 can be stably located at a predetermined position of the lead screw 720, thereby ensuring the stability and safety of the toe guard structure of the elevator car of the utility model.
[0065] In the exemplary embodiment of the present utility model, considering factors such as cost, the number of the motor 710 and the lead screw 720 are both set to 1 and are set at a position corresponding to the first track 410. Alternatively, the number of the motor 710 and the lead screw 720 can also be set to 2 at the same time, and they are respectively set at positions corresponding to the first track 410 and the second track 420, so as to be more conducive to maintaining the balance of both sides of the foot guard 300.
[0066] According to an exemplary embodiment of the present utility model, Figure 6As shown, a cam structure 341 is provided at the end of the rotating shaft 340. The footboard structure of the elevator car of the utility model further includes a first switch 800. The first switch 800 is provided at the lower part of the first mounting bracket 210 and has a first spring contact 810 and a first contact base 820, and when the footboard 300 rotates to the unfolded state, the cam structure 341 rotates with the rotating shaft 340 and presses against the first spring contact 810, so that the first spring contact 810 contacts the first contact base 820 to output a first electrical signal.
[0067] According to an exemplary embodiment of the present utility model, Figure 7 As shown, a contact plate 360 is provided at the lower part of the plate body 310. The toeboard structure of the elevator car of the utility model further includes a second switch 900. The second switch 900 is provided on the first track 410 and has a second spring contact 910 and a second contact base 920, and when the toeboard 300 rotates to the folded state, the second spring contact 910 contacts the second contact base 920 to output a second electrical signal.
[0068] The first switch 800 may generate a first electrical signal indicating that the toe guard 300 is in an unfolded state. The second switch 900 may generate a second electrical signal indicating that the toe guard 300 is in a folded state. The first electrical signal and the second electrical signal may serve as prompts to passengers or staff, thereby making the operation more intelligent. Alternatively, the first switch 800 and / or the second switch 900 may be electrically connected to an elevator control system, so that the elevator control system may control the operation of the elevator through the electrical signals generated by the first switch 800 and / or the second switch 900.
[0069] The operation of the toe guard structure of the elevator car according to the implementation scheme of the utility model will be described below in conjunction with the accompanying drawings.
[0070] In general, if Figure 3 As shown, the first slider 510 is at one end of the first track 410, and the footboard 300 is in a folded state to prevent the footboard from impacting the pit floor and causing damage to the equipment when the car is leveled at the bottom floor.
[0071] When the foot guard 300 is needed to be used, the output shaft 711 of the control motor 710 is rotated in the first rotation direction, so that the lead screw 720 rotates in the first rotation direction and drives the first slider 510 to slide in the first sliding direction along the first track 410. The sliding of the first slider 510 can drive the first support rod 610 to produce a first action, thereby driving the foot guard 300 to rotate in the unfolding direction. When the first slider 510 slides to one end of the first track 410, the first support rod 610 drives the foot guard 300 to rotate to the unfolded state.
[0072] After the foot guard 300 is used, the output shaft 711 of the control motor 710 rotates in the second rotation direction, so that the lead screw 720 rotates in the second rotation direction and drives the first slider 510 to slide in the second sliding direction along the first track 410. The sliding of the first slider 510 can drive the first support rod 610 to produce a third action, thereby driving the foot guard 300 to rotate in the folding direction. When the first slider 510 slides to the other end of the first track 410, the first support rod 610 drives the foot guard 300 to rotate to the folded state.
