[0040] The embodiments of the present application are described in detail below, examples of which are shown in the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0041] The pedal with weighing function of the embodiments of the present application is described below in combination with the drawings.

[0042] Referring to Figures 1-7 The pedal with weighing function 100 of the embodiments of the present application comprises a pedal body 1, a stepping plate 2 and a strain gauge 3. The pedal 100 can be installed on a vehicle, for example, at the bottom of the vehicle body and adjacent to the lower edge of the side door or tailgate of the vehicle, for assisting passengers to get on or off the vehicle. Of course, the pedal 100 can also be applied to other scenarios of assisting passengers to walk or stepping on.

[0043] The pedal body 1 has a supporting portion 11, a weighing area portion 12, a slot 14 and a deformation area portion 13. The slot 14 is arranged between the supporting portion 11 and the weighing area portion 12 to separate the supporting portion 11 and the weighing area portion 12. The deformation area portion 13 is connected between the supporting portion 11 and the weighing area portion 12. It can be understood that one of the supporting portion 11 and the weighing area portion 12 can surround the other. Preferably, the weighing area portion 12 is located in the middle of the supporting portion 11, and the supporting portion 11 and the weighing area portion 12 are concentric with each other.

[0044] Preferably, the deformation area portion 13 is multiple and uniformly arranged along the circumference of the weighing area portion 12. The supporting portion 11, the weighing area portion 12 and the deformation area portion 13 are all plate-shaped and integrally formed, and the multiple deformation area portions 13 are arranged along the circumference of the weighing area portion 12. The weighing area portion 12 can be circular and the multiple deformation area portions 13 are uniformly arranged along the circumference of the weighing area portion 12. Alternatively, the weighing area portion 12 can be rectangular or square polygonal and the multiple deformation area portions 13 are respectively located at the corner portions of the weighing area portion 12.

[0045] The support part 11 and the weighing area part 12 are separated by the slot 14, and a plurality of deformation area parts 13 are connected between the support part 11 and the weighing area part 12, so that the slot 14 is divided into a plurality of slot sections by the plurality of deformation area parts 13, and when the weighing area part 12 is stressed, for example, when a passenger steps on the weighing area part 12, the weighing area part 12 is displaced relative to the support part 11, so that the deformation area part 13 is deformed.

[0046] The stepping plate 2 is arranged on the weighing area part 12. When a passenger steps on the stepping plate 2, the weight of the passenger is applied to the weighing area part 12, and the deformation area part 13 is deformed. The strain gauge 3 is arranged on the deformation area part 13, and the strain gauge 3 is deformed with the deformation of the deformation area part 13, so that the weight of the passenger on the stepping plate 2 can be measured through the deformation of the strain gauge 3.

[0047] The stepping plate with the weighing function of the embodiment has the deformation area part formed between the support part and the weighing area part, and the strain gauge is arranged on the deformation area part and deformed with the deformation of the deformation area part, so that the weighing sensor is formed. In other words, part (the deformation area part on which the strain gauge is arranged) of the weighing sensor is formed by part of the stepping plate. Compared with the weighing sensor in the prior art, no separate additional elastic body needs to be arranged for each strain gauge, and no separate additional mounting structure needs to be used to mount each weighing sensor on the stepping plate body, the number of parts is reduced, the overall structure, assembly, mounting and dismounting and maintenance are simple, the processing and mounting precision requirements of the weighing sensor are low, and the measurement precision is high. Even if the stepping plate is exposed to the external environment for a long time, the weighing precision and the stability of the performance can be guaranteed.

[0048] The stepping plate 100 with the weighing function of some specific embodiments of the utility model is described below.

[0049] Referring to Figures 1-7 , the stepping plate 100 includes a stepping plate body 1, a stepping plate 2, a strain gauge 3, a first pressing plate 42, a second pressing plate 43, an upper waterproof pad 41, a lower waterproof pad 51 and a lower cover plate 52.

[0050] As shown in Figures 5-7 , the stepping plate body 1 has a support part 11, a weighing area part 12, a slot 14 and a deformation area part 13. The middle part of the upper surface of the stepping plate body 1 is concave to form a sink 15, and the support part 11, the weighing area part 12 and the deformation area part 13 are all located in the sink 15.

[0051] The support part 11, the weighing area part 12 and the deformation area part 13 are plate-shaped and integrally formed. The support part 11, the weighing area part 12 and the deformation area part 13 can be located on substantially the same plane. For example, the support part 11, the weighing area part 12 and the deformation area part 13 are cut and / or punched from the same plate. Alternatively, the support part 11, the weighing area part 12 and the deformation area part 13 can be integrally formed by die casting. The support part 11 and the weighing area part 12 are directly connected through the deformation area part 13.

[0052] In the embodiment, the support part 11 surrounds the weighing area part 12, the weighing area part 12 is located in the middle of the support part 11, and the support part 11 and the weighing area part 12 are concentrically arranged with each other. The weighing area part 12 and the support part 11 are both rectangular, and the deformation area part 13 is four, which is distributed at the four corners of the rectangular weighing area part 12.

[0053] The slot 14 is arranged between the support part 11 and the weighing area part 12 to separate the support part 11 and the weighing area part 12. The deformation area part 13 is connected between the support part 11 and the weighing area part 12. Specifically, the outer periphery of the weighing area part 12 and the inner periphery of the support part 11 are separated by the slot 14, the support part 11 is provided with four recessed parts 111 at positions corresponding to the four corners of the weighing area part 12, the four recessed parts 111 can be rectangular grooves, and the four deformation area parts 13 are respectively located at the four corners of the weighing area part 12 and in the recessed parts 111. The deformation area part 13 protrudes from the outer periphery of the weighing area part 12, the weighing area part 12 is rectangular, which can avoid the problem of stress concentration in the local area of the weighing area part 12, and further avoid the problem of deformation in the local area of the weighing area part 12 after the weighing area part 12 is frequently pressed, thereby avoiding the decrease of the measurement accuracy.

[0054] In the embodiment, the deformation area part 13 includes a deformation base 131, a deformation beam 132 and a cantilever beam 133. The deformation base 131 is connected with the support part 11, the first end of the deformation beam 132 is connected with the deformation base 131, and the second end of the deformation beam 132 is connected with the weighing area part 12. The fixed end of the cantilever beam 133 is connected with the deformation base 131, and the two sides of the deformation beam 132 are respectively provided with the cantilever beam 133. The deformation base 131 and the cantilever beam 133 are separated from the support part 11 by the slot 14, the cantilever beam 133 is separated from the deformation beam 132 by the slot 14, and the deformation beam 132 and the two cantilever beams 133 are substantially in the shape of M.

[0055] The strain gauge 3 is arranged on the deformation beam 132. Specifically, the strain gauge 3 can be directly attached to the surface of the deformation beam 132, for example, the strain gauge 3 can be bonded to the deformation beam 132, so as to timely respond to the deformation of the deformation area part 13, and the overall structure is simple and the measurement accuracy is high.

[0056] The deformation zone 13 can adopt a segmented structural design of deformation base 131 and deformation beam 132. The width of deformation base 131 is greater than the width of deformation beam 132, which can optimize the stress distribution of deformation zone 13, avoid the problem of local stress concentration, and improve fatigue resistance while ensuring the deformation sensitivity of deformation beam 132.

[0057] The cantilever beam 133 and the deformation beam 132 can be arranged parallel and spaced apart. The cantilever beam 133 and the support part 11 are separated by a slot 14. By setting the cantilever beam 133, the width of the slot 14 in the area corresponding to the deformation beam 132 can be reduced, so that the width of the slot 14 is consistent, which optimizes the structure of the pedal body and facilitates manufacturing.

[0058] like Figures 2-4 As shown, in this embodiment, the foot pedal 2 is disposed on the weighing area 12, and the upper waterproof pad 41 is disposed between the foot pedal 2 and the pedal body 1. The upper waterproof pad 41 is deformable and can be made of flexible rubber or other materials. Preferably, the upper waterproof pad 41 is a rubber pad, and the height of the inner periphery of the upper waterproof pad 41 is higher than the height of the outer periphery. The first pressure plate 42 and the second pressure plate 43 can be annular. Preferably, the first pressure plate 42 is an integral rectangular ring, and the second pressure plate 43 is an integral rectangular ring. The inner periphery of the upper waterproof pad 41 is pressed between the lower surface of the foot pedal 2 and the first pressure plate 42, and the outer periphery of the upper waterproof pad 41 is pressed between the upper surface of the pedal body 1 and the second pressure plate 43.

[0059] The upper waterproof pad 41 and the second pressure plate 43 are located inside the settling tank 15. The outer periphery of the upper waterproof pad 41 is pressed between the second pressure plate 43 and the bottom surface of the settling tank 15. The outer periphery of the second pressure plate 43 abuts against the peripheral wall of the settling tank 15, thereby reducing the gap between the second pressure plate 43 and the peripheral wall of the settling tank 15, and making the components fit more tightly.

[0060] The upper surface of the second pressure plate 43 and the upper surface of the inner periphery of the upper waterproof pad 41 are roughly flush with the upper surface of the pedal body 1. The upper end surface of the pedal 2 is higher than the exposed upper end surface of the upper waterproof pad 41 and the pedal body 1. On the one hand, this can prevent liquid from accumulating on the pedal and allow rainwater to slide off the pedal as quickly as possible. On the other hand, when a passenger steps on the pedal, the passenger's weight can be concentrated on the pedal 2. The passenger's weight is applied to the weighing area 12, causing the weighing area 12 to shift relative to the support 11, thereby deforming the deformation beam 132. The deformation of the strain gauge 3 more accurately reflects the weight of the person stepping on the pedal 2.

[0061] The first pressing plate 42 and the second pressing plate 43 can be made of a metal plate or a plastic plate with certain hardness. The first pressing plate 42 and the second pressing plate 43 can be connected with the pedal body through bolts or other fasteners. The inner periphery of the upper waterproof pad 41 and the pedal body 2 can be tightly attached together, and the outer periphery of the upper waterproof pad 41 and the pedal body 1 can be tightly attached together, so as to seal the top of the pedal and prevent water, mud and other sundries from entering the inside of the pedal from the top of the pedal.

[0062] The lower cover plate 52 is connected to the lower surface of the pedal body 1, and the lower waterproof pad 51 is arranged between the lower cover plate 52 and the pedal body 1. The lower waterproof pad 51 can be made of flexible rubber or gas material. For example, the lower waterproof pad 51 is a rubber gasket. The circumferential direction of the lower cover plate 52 is fixedly connected with the pedal body 1 through bolts or other fasteners, and the lower waterproof pad 51 is arranged between the lower cover plate 52 and the pedal body 1, so as to prevent water, mud and other sundries from entering the inside of the pedal from the bottom of the pedal.

[0063] Since the pedal is usually exposed to the external environment, the internal structure of the pedal is easily eroded by rain and snow when encountering rainy and snowy weather. When the pedal is applied to a vehicle, if the vehicle drives through water or drives on a muddy road, the pedal is easily immersed in water or bonded with mud, so that water, mud and other sundries enter the internal structure of the pedal. Therefore, in the present embodiment, the sealing of the pedal is realized by arranging the upper waterproof pad, the lower waterproof pad and the lower cover plate, so as to protect the weighing performance of the pedal from the influence of the external environment.

[0064] The lower cover plate 52 has a receiving cavity 521, and the circuit board 6 connected with the strain gauge 3 is arranged in the receiving cavity 521. The circuit board 6 can convert the deformation of the strain gauge 3 into an electrical signal output, obtain the weight of the object, and then display the weight through a display screen and / or give an overload warning through an alarm.

[0065] The pedal with the weighing function in the present embodiment has a deformation area part formed between the supporting part and the weighing area part, and the strain gauge is arranged on the deformation area part and deformed with the deformation of the deformation area part, so as to form a weighing sensor. Compared with the weighing sensor in the prior art, the present embodiment does not need to arrange a separate elastic body for each strain gauge, and does not need to use a separate mounting structure to mount the weighing sensor on the pedal body, so that the number of parts is reduced, the overall structure, assembly, installation and disassembly and maintenance are simple, the processing and installation precision of the weighing sensor is low, and the measurement precision is high. Even if the pedal with the weighing function is exposed to the external environment for a long time, the weighing precision and the stability of the performance can be guaranteed.

[0066] Referring to Figures 1-8The pedal device 200 of the embodiment of the present application comprises a telescopic assembly 7 and a pedal, the telescopic assembly 7 is connected with the pedal to drive the pedal to move between the extended position and the retracted position, and the pedal can be the pedal 100 with the weighing function in the above embodiment.

[0067] The telescopic assembly 7 comprises a mounting support 71, a driving shaft 72, a driving motor 73, a first driving arm 74, a first driven arm 75, a second driving arm 76 and a second driven arm 77. The driving shaft 72 is rotatably mounted on the mounting support 71, the driving motor 73 is mounted on the mounting support 71 and is in transmission connection with the driving shaft 72 to drive the driving shaft 72 to rotate in the forward and reverse directions. The pedal 100 has a first side (the left side shown in the figure) and a second side (the right side shown in the figure) along the axial direction of the driving shaft 72. Figure 8 Figure 8

[0068] The first end of the first driving arm 74 is fixedly connected with the driving shaft 72, and the second end of the first driving arm 74 is pivotally connected with the first side of the pedal 100. The first end of the first driven arm 75 is pivotally connected with the mounting support 71, and the second end of the first driven arm 75 is pivotally connected with the first side of the pedal 100. The first end of the second driving arm 76 is fixedly connected with the driving shaft 72, and the second end of the second driving arm 76 is pivotally connected with the second side of the pedal 100. The first end of the second driven arm 77 is pivotally connected with the mounting support 71, and the second end of the second driven arm 77 is pivotally connected with the second side of the pedal 100.

[0069] When the driving shaft 72 is driven to rotate by the driving motor 73, the first driving arm 74 and the second driving arm 76 can be swung, and the first driven arm 75 and the second driven arm 77 are synchronously swung, so that the pedal 100 can move between the extended position and the retracted position.

[0070] The pedal device 200 of the embodiment can reduce the requirement for the installation space by controlling the telescopic movement of the pedal, and improve the practicability and safety. For example, after the pedal device 200 is installed on the vehicle, it can be applied to the vehicle with a lower chassis. Meanwhile, the pedal is in the retracted position during the normal driving of the vehicle, and the pedal is prevented from being bumped.

[0071] The vehicle device of the embodiment of the present application comprises a vehicle and a pedal, the pedal is installed on the vehicle, and the pedal can be the pedal 100 with the weighing function in the above embodiment. The pedal 100 can be a fixed pedal or a telescopic pedal which is driven by the telescopic assembly to move between the extended position and the retracted position.

[0072] ​​When the vehicle has multiple side doors on one side of the vehicle, a pedal can be provided on the one side of the vehicle for the multiple side doors, or a pedal can be provided under each side door.

[0073] The pedal of the vehicle has a weighing function, when the weight on the pedal exceeds a preset value, an alarm can be provided on the vehicle to avoid damaging the pedal due to overloading, in addition, the weight signal can be displayed on the display screen of the vehicle, or uploaded to the cloud server, and can also be wirelessly transmitted to the mobile terminal, such as the user's mobile phone, and the information stored on the cloud server can also be directly viewed through the mobile terminal. Preferably, the preset value can be set and adjusted through the mobile phone or the vehicle display screen.

[0074] The weight signal detected by the pedal can be uploaded to the cloud server, and the cloud server can record the load information applied to the pedal and periodically generate a load change report of the pedal. The cloud server can also process and analyze the load information applied to the pedal to determine whether the pedal is overloaded and periodically generate an overload use report of the pedal. The cloud server can send the periodically generated load change report and overload use report to the mobile terminal, and the user can also actively view the load change report and use alarm report on the pedal through the mobile terminal.
