DETAILED DESCRIPTION
[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0017] like Figure 1 , Figure 2As shown, a lifting type plate vehicle comprises a base 1, a side stop assembly 2 fixedly arranged on one side of the top of the base 1, and a lifting platform 3 arranged on one side of the side stop assembly 2 and located above the base 1, wherein the side stop assembly 2 is used to support the lifting platform 3 and prevent the plates on the lifting platform 3 from sliding toward the side, wherein the side stop assembly 2 comprises a base 210 fixedly connected to the base 1 and vertically arranged, a driving mechanism 220 arranged in the base 210 and connected to the lifting platform 3 and driving the vertical movement, and a guiding mechanism 230 limiting the moving route of the lifting platform 3, wherein two groups of plate detection mechanisms 4 arranged vertically are arranged on the side of the lifting platform 3, wherein when the plate detection mechanism 4 at a higher position does not detect a plate and the plate detection mechanism 4 at a lower position detects a plate, the plate stacked on the lifting platform 3 is at the most suitable height for taking, and the plate detection mechanism 4 and the driving mechanism 220 are electrically connected to the controller;
[0018] The two sets of meal tray detection mechanisms 4 are respectively used to detect whether there are meal trays at the positions corresponding to their heights, and the controller controls the driving mechanism 220 to adjust the height of the lifting platform 3 according to the detection results;
[0019] When the higher position meal plate detection mechanism 4 detects a meal plate, it means that the meal plate on the lifting platform 3 is at a high level and is not convenient to take. At this time, the driving mechanism 220 drives the lifting platform 3 to descend until the top of the meal plate is lower than the higher position meal plate detection mechanism 4.
[0020] When the lower position meal plate detection mechanism 4 does not detect the meal plate, it means that the height of the meal plate on the lifting platform 3 is too low to be convenient for taking. At this time, the driving mechanism 220 drives the lifting platform 3 to rise until the height of the top of the meal plate is higher than the lower position meal plate detection mechanism 4;
[0021] In order to prevent the dinner plates from sliding off from both sides when placing and taking the dinner plates, in a further embodiment, side rails 5 fixedly connected to the base 1 are fixedly provided on both sides of the lifting platform 3;
[0022] Specifically, the meal tray detection mechanism 4 is arranged on the top of the side rail 5, and the meal tray detection mechanism 4 includes a transmitter and a receiver. Two groups of the transmitter and the receiver are respectively arranged on the side rails 5 on both sides. The transmitter and the receiver of the same group are located on the same horizontal plane and are arranged opposite to each other. When the height of the meal tray exceeds the meal tray detection mechanism 4, the meal tray will block the receiver from receiving the signal.
[0023] In order to improve the accuracy of the adjustment process of the lifting platform 3, in a further embodiment, the height difference of the two groups of the plate detection mechanisms 4 is no greater than the height of one plate. In the process of taking the plate, the driving mechanism 220 drives the lifting platform 3 to rise, so that the plate detection mechanism 4 at a lower position detects the plate. When the height difference of the two plate detection mechanisms 4 is no greater than the height of one plate, the height adjustment value of the lifting platform 3 is exactly the height of one plate each time.
[0024] In order to prevent too many plates from being stacked on the lifting platform 3, in a further embodiment, a distance detection mechanism 6 for measuring the distance between the lifting platform 3 and the base 1 is provided between the bottom of the lifting platform 3 and the base 1, and the distance detection mechanism 6 is electrically connected to the controller, and the controller is also connected to a voice prompter;
[0025] When the lifting platform 3 is at the lowest position, the height between the lifting platform 3 and the plate detection mechanism 4 is fixed, and can only accommodate a certain number of plates. That is, when the distance detection mechanism 6 detects the minimum distance, the voice prompter prompts that the loading is completed;
[0026] Specifically, Figure 2 As shown, two vertical slide grooves 211 are provided on one side of the base 210 close to the lifting platform 3, the driving mechanism 220 and the guiding mechanism 230 are respectively arranged in the two slide grooves 211, and a bracket 301 is detachably connected to the bottom of the lifting platform 3, and two sliders 302 extending into the two slide grooves 211 are fixedly provided on one side of the bracket 301, and the two sliders 302 cooperate with the driving mechanism 220 and the guiding mechanism 230 respectively;
[0027] The guide mechanism 230 is a guide rod vertically arranged in the slide groove 211 on one side, and a guide hole is provided on the slider 302 on one side and is slidably sleeved on the guide rod. The driving mechanism 220 is a screw rod vertically and rotatably arranged in the slide groove 211 on the other side, and a servo motor connected with the transmission. A screw hole is provided on the slider 302 on the other side and is matched with the screw thread. The servo motor drives the screw rod to rotate and drives the slider 302 to move vertically through the screw transmission.
[0028] Specifically, in order to improve the support strength of the bracket 301, in a further embodiment, a wedge-shaped reinforcing support plate 303 is fixedly connected between the bottom of the bracket 301 and the slider 302;
[0029] In order to facilitate the movement and position adjustment of the dining tray trolley, in a further embodiment, a moving assembly 7 is further provided at the bottom of the base 1 . In this embodiment, the moving assembly 7 is a universal wheel arranged at the bottom of the base 1 .
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
