Description

Technical Field

[0001] This utility model generally relates to the field of transportation technology, and more specifically, to a door anti-pinch mechanism and a shuttle bus. Background Technology

[0002] Airport shuttle buses, as a dedicated mode of transportation at airports, transport passengers from the waiting area to their aircraft, or from the terminal to the parking lot or nearby stations. When shuttle buses are in frequent use, the passenger flow in the cabin is large, sometimes reaching up to 110 people. This high density of people inside the vehicle makes it difficult for the driver to notice passengers near the doors in time. This can lead to a risk of passengers being injured by the cabin door when the driver closes the door after boarding, resulting in safety hazards and passenger complaints.

[0003] To address this, existing shuttle buses are equipped with door anti-pinch mechanisms. If the passenger door comes into contact with an obstacle during its movement, the anti-pinch mechanism is triggered, stopping the door from closing and preventing passengers from being pinched. The anti-pinch mechanism begins to fail during the entire door closing process, and the distance the door travels until it is fully closed is called the door anti-pinch failure distance. This failure distance is a crucial indicator of the safety of the door anti-pinch function; a shorter failure distance indicates a faster response time and more timely protection for passengers. However, if the door anti-pinch mechanism continues to operate, when the door is nearly fully closed, if it touches the bus body or a double-leaf door, the anti-pinch mechanism may cause the door to open accidentally, affecting the shuttle bus's safety and reliability.

The first detection component is used to detect the position of the first sensing component.

[0009] In some embodiments, the drive assembly further includes a master cylinder, and the drive member passes through the master cylinder and is slidable relative to the master cylinder;

[0010] The anti-pinch component also includes:

[0011] An anti-pinch cylinder is connected to the main cylinder, and the volume of the anti-pinch cylinder is smaller than the volume of the main cylinder;

[0012] A pressure detection device is at least partially disposed inside the anti-pinch cylinder, used to detect the actual pressure inside the anti-pinch cylinder.

[0013] In some embodiments, the anti-pinch component further includes:

[0014] An intake manifold, one end of which is connected to the main cylinder and the other end of which is connected to the anti-pinch cylinder, so that the air source in the main cylinder is delivered to the anti-pinch cylinder through the intake manifold;

[0015] An air outlet branch pipe is provided, with one end connected to the anti-pinch cylinder and the other end connected to the main cylinder, so that the air source in the anti-pinch cylinder is delivered to the main cylinder through the air outlet branch pipe.

[0016] In some embodiments, the driving component further includes:

[0017] The intake manifold assembly is connected to the main cylinder and is used to supply the air source to the main cylinder;

[0018] The exhaust manifold assembly is connected to the main cylinder and is used to discharge the air source in the main cylinder through the exhaust manifold assembly.

[0023] The sensing element is slidable relative to the adjustment shaft to adjust the position of the sensing element relative to the support element.

[0024] In some embodiments, the sensing element is at least partially L-shaped.

[0036] One embodiment of this utility model has the following advantages or beneficial effects:

[0037] This utility model provides a door anti-pinch mechanism and a shuttle bus. During the closing process, if the door comes into contact with an obstacle, the anti-pinch component can control the door's opening, preventing passengers from being pinched and thus improving driving safety and passenger experience.

[0038] When the drive unit drives the door to open or close, it simultaneously drives the moving part to move linearly. In other words, the moving part acts as a follower. When the first detection unit detects the position of the first sensing unit, the moving part can represent the movement position of the drive unit. This means that the door is in a state of near or close during the closing process, which triggers the anti-pinch failure component. This controls the anti-pinch failure distance, causing the anti-pinch component to fail. In other words, the anti-pinch component will not control the door to open, ensuring that the door can be closed reliably and avoiding the situation of the door being opened accidentally.

[0039] By setting a first sensing element on the moving part and / or the driving part, it is equivalent to adding a sensing point on the moving part. The first detection element detects the first sensing element that moves linearly back and forth with the moving part. The linear detection process is stable and not prone to fluctuations. It can effectively shorten the anti-pinch distance, and the debugging is simple and convenient, reducing maintenance costs. Attached Figure Description

[0056] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0057] This embodiment provides a door anti-pinch mechanism, suitable for public transportation vehicles, such as buses, subways, and shuttle buses. Figure 1 As shown, the door anti-pinch mechanism includes a drive assembly 1 and an anti-pinch assembly 2. The drive assembly 1 includes a drive member 11, which can be a drive rod or a drive shaft. The drive member 11 is connected to the door and can drive the door to move for opening and closing. The anti-pinch assembly 2 is configured to control the door to open when the door contacts an obstacle.

[0058] After passengers board the vehicle, the driver can control the drive unit 11 to move the door and close it. During the closing process, if the door comes into contact with an obstacle, such as cargo, luggage, or passengers, the anti-pinch component 2 can be used to activate the door opening function to prevent passengers from being pinched by the door, thereby improving driving safety and passenger experience.

[0059] For example, the number of doors can be one, with the vehicle body having an entrance and exit, and one door selectively blocking the entrance and exit, i.e., a single-door configuration; the number of doors can also be two, with the two doors moving towards or away from each other, i.e., a double-door configuration; the doors can be sliding doors that move relative to the vehicle body, or revolving doors that rotate relative to the vehicle body, to achieve opening and closing functions. This embodiment does not limit the number of doors or the opening method of the doors, and can be adjusted according to actual production conditions.

[0060] For example, the anti-pinch component 2 can be directly connected to the car door. For instance, the anti-pinch component 2 can be optionally installed on a position sensor on the car door. When the position sensor detects that the car door is in contact with an obstacle, the anti-pinch component 2 can directly activate the car door opening function. The anti-pinch component 2 can also be indirectly connected to the car door through the drive component 1. When the anti-pinch component 2 detects that the car door is in contact with an obstacle, the drive component 1 is used to control the car door to open.

[0061] The distance the door moves from the moment the anti-pinch component 2 fails during the closing process until the door is fully closed is called the door anti-pinch failure distance. This distance is a crucial indicator of the safety of the door anti-pinch function; the shorter the failure distance, the lower the risk of passenger injury. For example, if the failure distance is 100mm, a passenger's finger might be pinched and seriously injured; however, if the failure distance is reduced to 10mm, the passenger's finger might only be slightly pinched, or even completely avoided injury.

[0062] If the anti-pinch component 2 continues to operate, when the door is nearing closing, if the door touches the vehicle body or a double-leaf door, the anti-pinch component 2 may cause the door to open accidentally, affecting safety and reliability. Therefore, if... Figure 1 As shown, the door anti-pinch mechanism provided in this embodiment also includes an anti-pinch failure component 3. The anti-pinch failure component 3 includes a moving part 31, a first sensing element 32, and a first detection element 33. The moving part 31 is connected to the end of the driving part 11 away from the door, and the driving part 11 can drive the moving part 31 to move. The first sensing element 32 is connected to at least one of the driving part 11 and the moving part 31. The first detection element 33 is used to detect the position of the first sensing element 32 to control the door anti-pinch failure distance and cause the anti-pinch component 2 to fail.

[0063] For example, the first detection element 33 may be a detection switch, a position sensor, or the like. The first sensing element 32 may be made of a protrusion or other structure or a sensing material to facilitate identification by the first detection element 33. The first sensing element 32 may be disposed only on the driving element 11, or only on the moving element 31, or between the driving element 11 and the moving element 31, or separately on the driving element 11 and the moving element 31.

[0064] When the drive unit 11 drives the door to open or close, the drive unit 11 will simultaneously drive the moving part 31 to move linearly. That is, the moving part 31 plays a follow-up role. When the first detection unit 33 detects the position of the first sensing unit 32, the moving part 31 can represent the movement position of the drive unit 11, which means that the door is in a state of near or close during the closing process. At this time, the anti-pinch failure component 3 is triggered, and the anti-pinch failure distance is controlled, so that the anti-pinch component 2 fails. That is, the anti-pinch component 2 will not control the door to open, ensuring that the door can be closed reliably and avoiding the situation of the door being opened accidentally.

[0065] By setting the first sensing element 32 on the moving part 31 and / or the driving part 11, it is equivalent to adding a sensing point on the moving part 31. The first detection element 33 detects the first sensing element 32 that moves linearly back and forth with the moving part 31. The linear detection process is stable and not prone to fluctuations. It can effectively shorten the anti-pinch distance, and the debugging is simple and convenient, reducing maintenance costs.

[0066] In one embodiment, such as Figures 1-2 As shown, the door is connected to the door hinge 43. When the door is opened or closed, the door drives the door hinge 43 to rotate relative to the vehicle body. That is, the door uses a rotation method to realize the opening and closing process.

[0067] If the first sensing element 32 is located on the door hinge 43 or a cam coaxially mounted with the door hinge 43, the position of the door can be determined by inferring the rotation angle of the door hinge 43 based on the position of the first sensing element 32 detected by the first detection element 33. Using this rotational detection method, the distance at which the door anti-pinch fails is controlled by adjusting the rotation angle of the cam; the anti-pinch failure distance is approximately 100mm to 120mm. However, during vehicle debugging, it is necessary to adjust the minute rotation angle of the cam to reduce the anti-pinch failure distance, requiring high precision, making construction difficult, debugging inconvenient, and susceptible to weight changes during vehicle passenger transport. For example, if the passenger load is large, the door hinge 43 may sink with the vehicle body, affecting detection accuracy and leading to accidental door opening or failure to close.

[0068] Compared with the rotation detection method, this embodiment adopts linear movement detection. The first detection element 33 senses the first sensing element 32 that reciprocates with the moving element 31. The debugging structure is simple, the function is stable and not prone to fluctuation. The anti-pinch failure distance is about 10mm to 25mm, which effectively shortens the anti-pinch distance and is not affected by changes in the weight of the vehicle passengers, reducing the situation of passengers being pinched when the door closes and improving safety.

[0069] In one embodiment, the door anti-pinch mechanism further includes a relay 34, which is electrically connected to the first detection element 33 and is used to control the on / off state of the first detection element 33.

[0070] In one embodiment, such as Figures 1-3 As shown, the anti-pinch mechanism for the car door also includes a position detection component 4. The position detection component 4 includes a gear 41, a single cam 42, a second sensor 44, and a second detection component 45. The moving member 31 has a toothed groove, so the moving member 31 can be called a rack. The gear 41 meshes with the toothed groove. The single cam 42 is coaxially arranged with the gear 41. The door hinge 43 passes through the single cam 42 and the gear 41. As the driving member 11 drives the moving member 31 to move, the gear 41 rotates through the meshing of the toothed groove with the moving member 31, thereby rotating the single cam 42, which is coaxially arranged with the gear 41. The second sensor 44 can be an optional position limit switch. The second sensor 44 is located on the single cam 42. The second detection component 45 is configured to detect the position of the second sensor 44 to identify the position of the car door based on the rotation angle of the door hinge 43, thereby determining whether the car door is closed properly.

[0071] In another embodiment, the door anti-pinch mechanism further includes a second sensor 44 and a second detection element 45. The second sensor 44 is disposed on the moving member 31, and the second detection element 45 is used to detect the position of the second sensor 44 to identify the position of the door, thereby determining whether the door is closed in place. That is, a linear detection method is used to achieve door positioning detection, which is simple and convenient to debug, and has a relatively low debugging difficulty.

[0072] In one embodiment, such as Figure 1 As shown, the drive assembly 1 also includes a main cylinder 12, and a drive member 11 passes through the main cylinder 12 and is slidable relative to the main cylinder 12. Exemplarily, the drive member 11 may contact the inner wall of the main cylinder 12 and slide in cooperation with it, or it may not contact the inner wall of the main cylinder 12. By supplying or venting air into the main cylinder 12, the drive member 11 moves relative to the main cylinder 12. While opening and closing the door, the drive member 11 also drives the moving member 31 to move, thereby controlling the door anti-pinch failure distance.

[0073] It is understood that in some other embodiments, the drive component 1 includes drive components such as motors and hydraulic cylinders, and the output end of the drive component is connected to the drive component 11, which can also realize the linear motion of the drive component 11.

[0074] When a passenger is trapped in a car door and cannot be closed, an alarm is triggered in the driver's cab, requiring the driver to manually open the door. This response is slow, and passenger injuries can be severe. Therefore, the anti-pinch component 2 provided in this embodiment includes an anti-pinch cylinder 21 and a pressure detection element (not shown in the figure). The anti-pinch cylinder 21 is connected to the main cylinder 12, and the pressure detection element is at least partially disposed within the anti-pinch cylinder 21 to detect the actual air pressure within the anti-pinch cylinder 21.

[0075] For example, the cylinder detection component and the anti-pinch cylinder 21 can be set independently, and the cylinder detection component is fixed to the anti-pinch cylinder 21 by means of threads, welding or other methods; the cylinder detection component and the anti-pinch cylinder 21 can also be a single unit structure, that is, the anti-pinch cylinder 21 itself has a cylinder detection component.

[0076] The anti-pinch cylinder 21 has a smaller volume than the main cylinder 12; therefore, it can also be called a small cylinder. When a passenger is trapped by the door, the air pressure in the anti-pinch cylinder 21 changes rapidly. The air pressure inside the anti-pinch cylinder 21 rises instantaneously. For example, if the preset cylinder pressure is 0.5 MPa, when the actual air pressure inside the anti-pinch cylinder 21 exceeds 0.5 MPa, the anti-pinch door opening action is activated, and the main cylinder 12 drives the door to open, preventing passenger injury. This method utilizes the relatively small anti-pinch cylinder 21 to automatically activate the anti-pinch function, maximizing the reaction speed after a passenger is trapped. It offers fast response, high sensitivity, and reduces the anti-pinch force exerted by the door on the passenger.

[0077] For example, the door anti-pinch mechanism also includes a controller (not shown in the figure), which is electrically connected to the air pressure detection element and the main cylinder 12, so that when the actual air pressure in the anti-pinch cylinder 21 is greater than the preset air pressure, the main cylinder 12 is controlled to drive the door to open.

[0078] In one embodiment, such as Figure 1 As shown, the anti-pinch assembly 2 also includes an inlet branch pipe 22 and an outlet branch pipe 23. One end of the inlet branch pipe 22 is connected to the main cylinder 12, and the other end is connected to the anti-pinch cylinder 21, so that the air source in the main cylinder 12 is transported to the anti-pinch cylinder 21 through the inlet branch pipe 22. One end of the outlet branch pipe 23 is connected to the anti-pinch cylinder 21, and the other end is connected to the main cylinder 12, so that the air source in the anti-pinch cylinder 21 is transported to the main cylinder 12 through the outlet branch pipe 23.

[0079] For example, if an anti-pinch function needs to be added to the main cylinder 12, the anti-pinch cylinder 21 can be installed on the main cylinder 12 using the intake branch pipe 22 and the exhaust branch pipe 23. This makes the main cylinder 12 and the anti-pinch cylinder 21 appear to be in parallel, resulting in low modification costs and no impact on the normal operation of the main cylinder 12. Simultaneously, when the main cylinder 12 is intaked, the air source within the main cylinder 12 is delivered to the anti-pinch cylinder 21 through the intake branch pipe 22; when the main cylinder 12 is exhausting, the air source within the anti-pinch cylinder 21 is delivered to the main cylinder 12 through the exhaust branch pipe 23. In other words, the air flow paths within the main cylinder 12 and the anti-pinch cylinder 21 are approximately connected in series, allowing changes in air pressure within the anti-pinch cylinder 21 to characterize changes in air pressure within the main cylinder 12.

[0080] It is understandable that there can be two doors, two drive components 1, two anti-pinch components 2 and two anti-pinch failure components 3. The two doors, two drive components 1, two anti-pinch components 2 and two anti-pinch failure components 3 are set up accordingly, and the opening and closing, anti-pinch and anti-pinch failure functions of the two doors can be controlled respectively.

[0081] In one embodiment, such as Figure 1 As shown, the drive assembly 1 also includes an intake manifold assembly 13, which is connected to the main cylinder 12 and is used to supply air to the main cylinder 12.

[0082] For example, the intake manifold assembly 13 includes a first intake manifold 131, an intake connector 132, and two second intake manifolds 133. The intake connector 132 is a three-way connector. The first intake manifold 131 is used to introduce an air source. The first intake manifold 131 is connected to the inlet of the intake connector 132. The two outlets of the intake connector 132 are respectively connected to two main cylinders 12 through the two second intake manifolds 133. After the air source passes through the first intake manifold 131 and the intake connector 132, it is supplied to the two main cylinders 12 through the two second intake manifolds 133, so as to realize the synchronous opening of the two doors.

[0083] In one embodiment, the drive assembly 1 further includes an exhaust pipe assembly 14, which is connected to the main cylinder 12 and is used to discharge the air source in the main cylinder 12 through the exhaust pipe assembly 14.

[0084] For example, the exhaust pipe assembly 14 includes a first exhaust pipe 141, an exhaust connector 142, and two second exhaust pipes 143. The exhaust connector 142 is a three-way connector. The two inlets of the exhaust connector 142 are connected to the two main cylinders 12 respectively through the two second exhaust pipes 143. The outlet of the exhaust connector is connected to the first exhaust pipe 141, so that the air source in the two main cylinders 12 passes through the second exhaust pipes 143 and the exhaust connector 142, and is discharged through the first exhaust pipe 141, so as to simultaneously discharge the air source in the two main cylinders 12 and realize the closing of the two doors.

[0085] It is understood that this embodiment uses air intake to open the door and air exhaust to close the door as an example. Of course, in other embodiments, the door can also be opened by exhaust and closed by air intake.

[0086] In one embodiment, such as Figure 1 As shown, the drive assembly 1 also includes a control valve 15 and a main pipeline 16. The control valve 15 can be a five-position three-way valve. The three ports of the control valve 15 are respectively connected to the first intake main pipeline 131, the first exhaust main pipeline 141 and the main pipeline 16. By switching the working position of the control valve 15, the switching of the intake and exhaust processes can be realized.

[0087] In one embodiment, such as Figure 1 and Figure 4 As shown, the first sensing element 32 includes a support part 321, an adjusting shaft 322 and a sensing part 323. The support part 321 is disposed between the driving member 11 and the moving member 31. The adjusting shaft 322 is disposed on the support part 321 and extends along the axial direction of the driving member 11. The sensing part 323 is sleeved on the outside of the adjusting shaft 322. The first detection element 33 is used to detect the position of the sensing part 323.

[0088] The sensing part 323 can slide relative to the adjusting shaft 322 to adjust the position of the sensing part 323 relative to the support part 321, thereby adjusting the anti-pinch failure distance.

[0089] Of course, after adjusting the position of the sensing part 323 relative to the support part 321, the sensing part 323 can be locked onto the adjusting shaft 322 by means of a locking nut or other fastener.

[0090] In one embodiment, the sensing part 323 is at least partially L-shaped. Whether the detection direction of the first detection element 33 is along the axial direction of the driving element 11 or perpendicular to the axial direction of the driving element 11, the L-shaped structure of the sensing part 323 can be perpendicular to the detection direction of the first detection element 33, facilitating detection by the first detection element 33 and improving detection accuracy.

[0091] In some other embodiments, the first sensing element 32 may also be an integral structure, that is, the support part 321 and the sensing part 323 are integrally formed, reducing the number of parts assembly steps and saving installation costs.

[0092] This embodiment also provides a shuttle bus, including the above-mentioned door anti-pinch mechanism. During the use of the shuttle bus, it avoids passengers being pinched by the door, improves the safety factor of the vehicle. By adding a sensing point on the moving part 31, the first detection part 33 detects the first sensing part 32 that moves linearly back and forth with the moving part 31. The linear detection process is stable and not prone to fluctuations. It can effectively shorten the anti-pinch distance, and the debugging is simple and convenient, reducing maintenance costs.

[0093] It should be noted that the embodiments of this utility model are merely one example of the principles employed by the present utility model, as shown in the accompanying drawings and described herein. Those skilled in the art will clearly understand that the principles of this utility model are not limited to any details or components of the apparatus shown in the accompanying drawings or described in the specification.
