DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer and more apparent, the present application will be further described in detail below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are only intended to explain the present application and not to limit the present application.

[0028] Please refer to Figures 1 to 10 , which is a button protection structure with double operation modes as the best embodiment of the present application, comprising a fixed base 100, a flip type protection cover 200 and a center press component 300, wherein: As Figure 3 , 4 shown, the fixed base 100 is connected with the driver's cabin side wall, having a square-shaped mounting slot 130 penetrating through the front and back sides thereof, used for bearing the flip type protection cover 200 and positioning the emergency brake button.

[0029] In the present embodiment, the fixed base 100 is composed of three layers of square frames 110, wherein the inner side of each square frame 110 is provided with a slot 120, and the three slots 120 are combined to form the aforementioned mounting slot 130.

[0030] The slots 120 of the innermost square frame 110 are integrally extended to the upper ends of the slots 120 of the outermost square frame 110 on both sides to form two clamping portions 140, and the two clamping portions 140 are each formed with a rotating clamping groove 141 distributed along the same axial direction, and the two clamping portions 140 are extended to a position not exceeding the outermost square frame 110. In the present embodiment, the two clamping portions 140 are each extended to a position flush with the outermost square frame 110.

[0031] Further, as Figure 4 shown, the flip type protection cover 200 is rotationally connected with the mounting slot 130, used for covering the emergency brake button in normal state.

[0032] In the present embodiment, the overall shape of the flip type protection cover 200 is adapted to the shape of the square-shaped mounting slot 130, and there is a gap left for easy flipping; the upper ends of the flip type protection cover 200 are inwardly recessed to form a clearance slot 210 adapted to the clamping portion 140, and a protrusion is formed on the clearance slot 210 to form a pivot shaft 220 buckled and rotationally matched with the rotating clamping groove 141, and the two pivot shafts 220 and the two rotating clamping grooves 141 are on the same rotating axis, so that after the two pivot shafts 220 are respectively clamped into the rotating clamping grooves 141 on both sides, the entire flip type protection cover 200 can be freely flipped in the mounting slot 130 to form the protection basis of the entire protection device.

[0033] In particular, in the present embodiment, the arc corresponding to the cross section of the rotating clamping groove 141 is an optimal arc, and a gap is reserved for clamping the pivot shaft 220, so that the buckling fixation of the pivot shaft 220 and the rotating process of the pivot shaft 220 relative to the rotating clamping groove 141 can be stably realized.

[0034] In order to better realize the rotation opening of the flip protective cover 200, for example, keeping the flip open state without folding down, the assembly gap between the rotation clamping groove 141 and the pivot shaft 220 can be designed to have a small assembly tolerance, so as to realize the clamping effect of similar damping rotation, thereby realizing the arbitrary angle hovering of the flip protective cover 200.

[0035] In addition, the rotation clamping groove 141 and the pivot shaft 220 can also be directly replaced by a mature damping rotation structure, thereby realizing the above process, which is not limited here.

[0036] As shown in Figure 2 , 3 , 6, the center pressing and elastic component 300 is arranged in the mounting groove 130 and located between the flip protective cover 200 and the emergency brake button, for transmitting the pressing force to the emergency brake button.

[0037] In this embodiment, as shown in Figure 5 , 6 , 7, the center pressing and elastic component 300 includes a rigid conducting piece 400 and a reset spring 500, the rigid conducting piece 400 is arranged to slide in the direction approaching or away from the emergency brake button, and the reset spring 500 is arranged between the rigid conducting piece 400 and the emergency brake button, for resetting the rigid conducting piece 400.

[0038] Specifically, as shown in Figure 2 , 3 , 6, it further includes a bottom box 600, the bottom box 600 is attached to the inner side of the flip protective cover 200, and the rigid conducting piece 400 is arranged in the bottom box 600.

[0039] In this embodiment, the bottom box 600 is box-shaped, the front side is open, and an installation cavity 610 is formed in the inside, a clearance hole 620 is arranged in the center of the inner bottom of the installation cavity 610, and the bottom box 600 is used to be fixed and installed on the driver's cabin side wall together with the fixed base 100, and after the installation is completed, the emergency brake button is located in the position opposite to the clearance hole 620.

[0040] In addition, in combination with Figure 6 , 9 , the inner bottom of the bottom box 600 and the side of the clearance hole 620 are provided with a guide structure matched with the bearing plate 420, the guide structure is three rod-shaped guide shafts 630 uniformly distributed around the side of the clearance hole 620, and the bearing plate 420 is provided with a guide hole 421 slidably matched with the guide shaft 630.

[0041] Furthermore, in this embodiment, the end of the guide shaft 630 extends beyond the opening of the bottom box 600 but does not exceed the edge of the outermost square frame 110, thereby allowing the guide shaft 630 to enter the coverage area of ​​the flip-type protective cover 200. On the inner sidewall of the flip-type protective cover 200, there are positioning holes 230 in the same number and opposite positions as the guide shaft 630. Thus, through the engagement of the guide shaft 630 and the guide hole 421, the entire bottom box 600 can be stably attached to the inner sidewall of the flip-type protective cover 200, so that it can rotate stably with the flip-type protective cover 200.

[0042] In addition, to enhance the connection strength between the bottom box 600 and the flip-top protective cover 200, structural reinforcement can also be achieved by adding adhesives, snaps, or other means, which are not limited here.

[0043] In this embodiment, the bottom of the base box 600 and the bottom of the flip-top protective cover 200 are flush, and the gap between the flip-top protective cover 200 and the bottom surface of the mounting groove 130 is adapted to the size of the gap when the flip-top protective cover 200 is closed, so that when the flip-top protective cover 200 drives the base box 600 to flip outward, the base box 600 will not interfere with the bottom surface of the mounting groove 130, so that it can be turned out smoothly.

[0044] In particular, such as Figure 1 , 2 As shown in Figure 6, the flip-type protective cover 200 has a notched area 250 on the side away from its rotation axis, and the notched area 250 is connected to the mounting groove 130.

[0045] In this embodiment, the notched area 250 is located on the lower right side of the flip-type protective cover 200, and is achieved by cutting off an inclined edge of the flip-type protective cover 200. Thus, the design of the notched area 250 makes it easy for operators to quickly flip the protective cover, and avoids accidental snagging caused by structural protrusions, thus taking into account both ease of operation and safety of use.

[0046] In this embodiment, an L-shaped limiting edge 260 extends integrally inward (vertically toward the mounting groove 130) from the notched corner position of the flip-type protective cover 200. The limiting edge 260 includes a horizontal section 261 integrally connected to the flip-type protective cover 200 and a vertical section 262 vertically connected to the lower end of the side of the horizontal section 261 away from the flip-type protective cover 200. Thus, a downwardly opening lock is formed between the vertical section 262, the horizontal section 261, and the notched corner area 250 of the flip-type protective cover 200. The locking groove 263 is designed such that the extension length of the vertical section 262 causes the locking groove 263 to at least partially protrude from the innermost square frame 110 (near the emergency brake button). This allows a square-hole key lock to be installed on the driver's cab side wall at the lower right corner of the entire fixed base 100. The latch of the square-hole key lock is designed to cover the locking groove 263, thus enabling the flip-top protective cover 200 to be normally closed, preventing passengers or staff from accidentally opening it. When preventative opening of the emergency brake button is required, the square-hole key can be rotated to move its latch away from the locking groove 263, releasing the restriction on the flip-top protective cover 200. The flip-top protective cover 200 can then be opened smoothly, putting the emergency brake button into standby mode.

[0047] In this embodiment, in order to adapt to the notched area 250 and further facilitate user operation, the lower right corner of the bottom box 600, which is directly opposite the notched area 250, is also provided with a clearance area 650 that is adapted to the shape and size of the notched area 250. After the bottom box 600 is attached to the inside of the flip-type protective cover 200, the limiting edge 260 extends into the coverage area of ​​the clearance area 650, so that after the user's hand is inserted into the mounting groove 130 along the notched area 250, convenient operation can be achieved within the clearance area 650, avoiding interference with the user's hand operation caused by the bottom box 600 in its complete form.

[0048] Meanwhile, the support plate 420 that slides inside the base box 600 also has a slanted notch (not shown in the figure) at its lower right corner to adapt the shape.

[0049] The rigid transmission member 400 includes an operation button 410, a bearing plate 420, and a transmission rod 430 arranged sequentially along the same axis. The end of the transmission rod 430 is directly opposite the emergency brake button, and the emergency brake button is within the range formed by the forward and backward movement of the entire rigid transmission member 400.

[0050] Combination Figure 6 , 7In the embodiment, the operation button 410, the bearing plate 420 and the conducting rod 430 are integrally formed, the operation button 410 is similar in shape to the emergency brake button and is used to simulate the emergency brake button for easy identification; the bearing plate 420 serves as the structural basis of the entire rigid conducting member 400 and plays the role of support and guidance, and the conducting rod 430 is columnar in shape and is provided with an arc-shaped guide corner 431 at the end away from the bearing plate 420.

[0051] Therefore, the rigid conducting effect can be achieved through the operation button 410, the bearing plate 420 and the conducting rod 430, and after the user presses the operation button 410, the entire rigid conducting member 400 is pushed to overcome the elastic force of the reset spring 500, thereby directly conducting pressure to the emergency brake button.

[0052] Because of the presence of the reset spring 500, the user still needs to overcome the elastic force of the reset spring 500 when operating the entire rigid conducting member 400 to make the conducting rod 430 touch the emergency brake button, so that the situation of accidental touch can be greatly avoided, and the entire rigid conducting member 400 is arranged in the mounting groove 130, so the user still needs to put his hand into the range of the mounting groove 130 when operating, thereby further avoiding the situation of accidental touch.

[0053] As shown in Figure 6 The bottom of the mounting cavity 610 and the side of the clearance hole 620 are provided with a ring-shaped limiting groove 640, and the end of the reset spring 500 is embedded in the limiting groove 640.

[0054] During installation, only one end of the reset spring 500 needs to be sleeved into the limiting groove 640, then the conducting rod 430 of the entire rigid conducting member 400 is aligned with the clearance hole 620, and the guide holes 421 on the bearing plate 420 are respectively aligned with the three guide shafts 630 and inserted, at this time the conducting rod 430 is synchronously inserted into the reset spring 500, and the other end of the reset spring 500 gradually contacts the inner side wall surface of the bearing plate 420 with the gradual pushing of the rigid conducting member 400, and after the end of the reset spring 500 completely contacts the inner side wall surface of the bearing plate 420, the installation process of the entire rigid conducting member 400 is completed.

[0055] At this time, the reset spring 500 is in an uncompressed state, and the operation button 410 is in the outermost position under the guidance and support of the guide shaft 630 and the reset spring 500. After the flip protective cover 200 is flipped and closed, the end of the guide shaft 630 is embedded in the positioning hole 230, and the outer side of the entire rigid conductor 400 is also blocked by the flip protective cover 200 to avoid being pulled out. After the operation button 410 is pressed, the operation button 410 drives the carrier plate 420 and the conducting rod 430 to move towards the emergency stop button at the accommodation hole 620. In this process, the carrier plate 420 moves stably under the guidance of the guide shaft 630, and the reset spring 500 is compressed and stored. After the pressing is completed and the emergency stop button is correctly triggered, the user releases the operation button 410, so that the reset spring 500 releases the elastic force to eject the carrier plate 420, and the operation button 410 can be reset.

[0056] In this process, since the user's hand is not instantaneously withdrawn, the reset spring 500 will eject the carrier plate 420 during the gradual withdrawal of the user's hand, so that the operation button 410 is gradually reset under the limitation of the user's hand, avoiding the entire rigid conductor 400 being directly ejected.

[0057] In particular, as shown in Figure 1 、 2 , 4, 8, the center of the flip protective cover 200 is provided with an operation hole 240 opposite to the position of the operation button 410.

[0058] In this embodiment, the operation button 410 partially protrudes from the second square box 110 in the initial position (i.e., when the reset spring 500 is not compressed), and does not exceed the end position of the guide shaft 630, so that the operation button 410 can be partially embedded in the operation hole 240 of the flip protective cover 200 in the normal state, facilitating direct operation by the user.

[0059] At the same time, the operation button 410 partially embedded in the operation hole 240 can also avoid the problem of easy misoperation caused by excessive protrusion of the operation hole 240. Only in a real emergency situation, the user will put his hand into the operation hole 240 to control the operation button 410.

[0060] Specifically, the middle part of the flip type protective cover 200 is provided with linearly distributed mounting holes 270 formed in the horizontal direction, the mounting holes 270 pass through the center of the operation hole 240, the operation button 410 is provided with pin shaft holes 411 formed in the horizontal direction, the cross-sectional diameter of the mounting holes 270 and the pin shaft holes 411 is the same, and another rod-shaped limiting pin 700 with the same cross-sectional diameter is inserted into the mounting holes 270 and the pin shaft holes 411, so that the operation button 410 is limited in the operation hole 240, at this time, the user needs to break the limiting pin 700 before pressing the operation button 410, and through the setting of the limiting pin 700, the situation of accidental touch can be further avoided, and the emergency trigger function in emergency situation is not affected.

[0061] In the embodiment, the flip type protective cover 200 is combined with the center press component 300. Figure 10 The material of the limiting pin 700 can be brittle plastic or light wood, and a ring-shaped material reducing groove 710 is formed on the left and right sides of the center of the limiting pin 700, the distance between the two material reducing grooves 710 is adapted to the diameter of the operation button 410, so that it can fall into the gap position between the operation button 410 and the operation hole 240, and the breaking position is just between the operation button 410 and the operation hole 240 after the user presses the operation button 410 in emergency situation, which further improves the convenience of operation.

[0062] In addition, the flip type protective cover 200, the fixed base 100 and the bottom box 600 are made of polycarbonate material, which has the characteristics of flame retardation and ultraviolet aging resistance. Stainless steel and other metal materials can also be used as needed, which is not limited here.

[0063] The beneficial effects of the present application are as follows: The flip type protective cover 200 and the center press component 300 can realize two trigger modes of the emergency brake button, which can realize emergency trigger and preventive trigger, and do not need to be used destructively, so as to achieve the comprehensive effect of preventing accidental touch, convenient operation, reusability and preventive preparation ability.

[0064] Specifically, in an emergency, the operator does not need to flip the flip cover 200, directly presses the center pressing and elastic component 300 in the operation hole 240 with fingers, breaks the limiting pin 700 after applying pressure, and then makes the pressure reach the emergency brake button smoothly to achieve the purpose of rapid triggering; in normal state, the mechanical lock (such as a square hole key lock) of the driver's room side wall is normally rotated into the locking groove 263, and the limiting flip cover 200 is flipped; in a preventive situation, such as when the train enters a risk area, the operator can rotate the square hole key lock in advance to make the lock tongue rotate out of the locking groove 263, release the limiting of the flip cover 200, and then flip the flip cover 200 to the open position, so that the emergency brake button is in a standby state, and if there is no abnormal situation, the flip cover 200 is reset after the train leaves, realizing preventive operation in an emergency.

[0065] In particular, the present application adopts a non-destructive structure, the flip cover 200 and the center pressing and elastic component 300 can be reused, only the limiting pin 700 broken due to an emergency needs to be replaced, thereby greatly increasing the design service life of the entire emergency brake button protection device, and greatly saving the cost of spare parts procurement, inventory management and maintenance replacement of manpower and materials.

[0066] In addition, the flip cover 200 completely covers the emergency brake button in normal state, and the operation hole 240 is only suitable for accurate pressing with fingers, effectively avoiding passenger mis-touch (especially for children, unconscious touch, etc.), and fully realizing anti-mis-touch.

[0067] In addition, the design of the notched area 250 away from the rotating shaft side of the flip cover not only facilitates the operator to quickly flip the cover, but also avoids accidental hooking due to structural protrusions, and takes into account the operation convenience and use safety.
