[0032] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Example:

[0034] See also Figure 1 , Figure 1 A schematic structural diagram of an emergency valve 10 provided in an embodiment of the present invention applied to a bus 100.

[0035] The embodiment of the present invention provides an emergency valve 10, which is easy to operate and can be applied to public transportation equipment such as buses 100 and trains. Of course, the emergency valve 10 can also be used independently.

[0036] In which, taking the application of the emergency valve 10 to a bus 100 as an example, the bus 100 includes the emergency valve 10, a body 20 and a door assembly 30, both of which are mounted on the body 20, and the emergency valve 10 is connected to the door assembly 30, and the operator can control the door assembly 30 to open or close through the emergency valve 10, especially in an emergency such as a malfunction of the bus 100. It should be noted that the emergency valve 10 is connected to the control circuit or the air circuit that controls opening and closing of the door assembly 30.

[0037] Since the bus 100 adopts the emergency valve 10 provided by the embodiment of the present invention, the bus 100 is also easy to operate.

[0038] The structural composition, working principle and beneficial effects of the emergency valve 10 provided in the embodiment of the present invention will be specifically introduced below.

[0039] See also Figure 2 , Figure 3 and Figure 4 , Figure 2 A schematic structural diagram of an emergency valve 10 provided in an embodiment of the present invention. Figure 3 This is a schematic cross-sectional structural diagram of the emergency valve 10 provided in an embodiment of the present invention when no pressing operation is performed. Figure 4 This is a schematic cross-sectional view of the emergency valve 10 provided in an embodiment of the present invention when no pressing operation is performed. Figure 3 and Figure 4 , the respective left arrow directions are first directions, and the respective right arrow directions are second directions.

[0040] The emergency valve 10 includes a push assembly 17, a base 15 and a valve body 12. The base 15 is installed on the vehicle body 20. The valve body 12 is connected to the door assembly 30, and the valve body 12 can control the opening and closing of the door assembly 30 by switching its own connection state. The push assembly 17 is set on the base 15 and connected to the valve body 12, so that the operator can switch the connection state of the valve body 12 by pressing to control the door assembly 30, and its operation is relatively simple.

[0041] Specifically, the pressing assembly 17 includes a pressing member 172, a limiting member 173, a locking member 174 and a locking elastic member 175. The pressing member 172 is slidably connected to the base 15 for the operator to press. The limiting member 173 is installed on the base 15, and the locking member 174 is rotatably connected to the pressing member 172. The pressing member 172 can move relative to the base 15 along a first direction, and the first direction is the extension direction of the limiting member 173.

[0042] Furthermore, the positioning member 174 is located between the limiting member 173 and the pressing member 172, and the positioning member 174 and the limiting member 173 are both extended along the first direction. In other words, the limiting member 173, the positioning member 174 and the pressing member 172 are arranged in sequence, and the three are all extended along the same direction. A first positioning portion 1743 is convexly provided on the side of the positioning member 174 away from the pressing member 172, or in other words, a first positioning portion 1743 is convexly provided on the side of the positioning member 174 close to the limiting member 173, and the first positioning portion 1743 is located between the limiting member 173 and the positioning member 174, and the positioning member 174 is provided with a first positioning portion 1743. The positioning elastic member 175 is arranged between the pressing member 172 and the locking member 174. The positioning elastic member 175 has an elastic force so that the first locking portion 1743 is abutted against the side of the limiting member 173, and the first locking portion 1743 has a tendency to turn to the limiting member 173. In other words, the positioning elastic member 175 exerts an elastic force to drive the locking member 174 to rotate, so that the first locking portion 1743 is abutted against the side of the limiting member 173 close to the locking member 174, and the part of the locking member 174 having the first locking portion 1743 has a tendency to turn to the limiting member 173.

[0043] When the push member 172 moves along the first direction, or when the operator presses the push member 172 along the first direction, since the push member 172 is connected to the valve body 12, the push member 172 can switch the connectivity state of the valve body 12, and the push member 172 can also drive the first clamping portion 1743 to move along the side of the limiting member 173 and extend out of the first limiting end 1731, and make the first clamping portion 1743 abut against the end face of the first limiting end 1731 to maintain the above-mentioned connectivity state, wherein the first limiting end 1731 is one end of the limiting member 173. In other words, the locking member 174 moves along the first direction with the pressing member 172. Since the first locking portion 1743 abuts against the side of the limiting member 173 under the action of the locking elastic member 175, the first locking portion 1743 will move along the side of the limiting member 173. When the first locking portion 1743 just extends out of the first limiting end 1731, the first locking portion 1743 will also turn to the side of the limiting member 173 away from the locking member 174 under the action of the locking elastic member 175. At this time, the first locking portion 1743 protruding from the side of the locking member 174 away from the pressing member 172 will abut against the end face of the first limiting end 1731 to limit the pressing member 172 from moving in a second direction opposite to the first direction, thereby limiting the pressing member 172 from driving the valve body 12 again to maintain the connection state of the valve body 12.

[0044] In this way, the operator can operate the valve body 12 by pressing or pulling the push member 172. The operation has low requirements for gripping, is more convenient, and avoids the phenomenon of difficult operation.

[0045] It should be noted that, in the present embodiment, one end of the limit member 173 is connected to the base 15, the valve body 12 is connected to one end of the push member 172, and the valve body 12 is located at the end of the limit member 173 away from the base 15, and the first limit end 1731 is the end of the limit member 173 close to the valve body 12. In other embodiments, the valve body 12 may also be located at the side position of the push member 172, or the side position of the limit member 173, which is connected to the push member 172, and the push member 172 moves along the first direction to switch the state of the valve body 12.

[0046] In addition, it should be noted that a plurality of strip holes may be provided on the limit member 173, and the length direction of the strip holes is perpendicular to the first direction, so that when the push member 172 moves along the first direction, the first locking portion 1743 may be respectively locked into each strip hole, so that the valve body 12 can realize the switching of multiple states.

[0047] Furthermore, the base 15 has an installation side 151 and an operating side 152 on opposite sides thereof, and a pressing hole 153 penetrating the installation side 151 and the operating side 152 is provided on the base 15. The installation side 151 is used to connect with the vehicle body 20. In other words, when the base 15 is installed on the vehicle body 20, the operating side 152 is arranged to face away from the vehicle body 20, so that the operator can operate the operating side 152 conveniently.

[0048] In addition, the push member 172 is slidably connected to the inner wall of the push hole 153 and is arranged in the push hole 153. That is to say, the push member 172 is arranged in the push hole 153 and is slidably connected to the inner wall of the push hole 153. The limiting member 173 is installed on the installation side 151, and the limiting member 173 extends along the axial direction of the push hole 153. In other words, the limiting member 173, the push member 172 and the locking member 174 all extend along the axial direction of the push hole 153. The first direction is a direction on the axis of the push hole 153. In addition, one end of the push member 172 also extends to the operating side 152. In other words, the push member 172 is partially located on the operating side 152. In this way, the operator can directly perform a pressing operation on the operating side 152, further improving its convenience.

[0049] It should be noted that, in other embodiments, the base 15 may also be of other shapes, which are slidably connected to the push member 172 so that the push member 172 can slide along the first direction relative to the base 15. In other implementations, the push member 172 may also be located in the push hole 153. At this time, the first locking portion 1743 is located near the end of the limiting member 173 close to the operating side 152. The operator can pull the push member 172 from the pressing hole 153 to drive the valve body 12 to switch its state, and make the first locking portion 1743 abut against the end face of the first limiting end 1731 of the limiting member 173 close to the operating side 152 to maintain the connection state of the valve body 12.

[0050] Please continue reading Figure 3 and Figure 4 One end of the pressing member 172 extending to the operating side 152 is the pressing end 1724, and the pressing end 1724 is used for the operator to press along the first direction, or in other words, the operator can press the above-mentioned pressing end 1724 on the operating side 152, and the two ends of the locking member 174 are respectively a locking connection end 1741 and a locking end 1742, and the locking connection end 1741 is rotatably connected with the pressing end 1724 to rotatably connect the locking member 174 and the pressing member 172, that is, the rotation connection between the locking member 174 and the pressing member 172 is located on the operating side 152.

[0051] In this way, the operator can clamp the pressing end 1724 and the locking connecting piece on the operating side 152 to enable the first locking portion 1743 to overcome the elastic force of the locking elastic piece 175 and rotate away from the limiting piece 173 to release the abutment between the first locking portion 1743 and the end face of the limiting end, so that the pressing piece 172 can move in a second direction opposite to the first direction, and then switch the connection state of the valve body 12, so that the valve body 12 and the pressing assembly 17 can complete the reset.

[0052] Furthermore, the first locking portion 1743 is located on the locking end 1742, or in other words, the first locking portion 1743 is located on the side of the locking end 1742 away from the pressing member 172. By setting a position farther away from the rotation position of the locking member 174, the first locking portion 1743 can move a farther distance to the side of the limiting member 173 away from the pressing member 172 when the locking member 174 rotates at a smaller angle, so as to improve the end face supporting effect of the first locking portion 1743 and the first limiting end 1731, and reduce the rotation space caused by reducing the locking.

[0053] It should be noted that the end of the pressing member 172 away from the pressing end 1724 is the pressing connection end 1725. In the present embodiment, the pressing connection end 1725 is connected to the valve body 12. In addition, in the present embodiment, the pressing end 1724 and the locking connection end are connected by a hinge, and the locking elastic member 175 is a torsion spring, which is arranged at the rotating shaft 192 of the above-mentioned hinge to drive the locking member 174 to flip toward the limiting member 173. In other embodiments, the locking member 174 can be rotatably connected to the middle part of the pressing member 172, and the middle part or other positions of the locking member 174 are rotatably connected to the pressing member 172, and the locking elastic member 175 can also be other elastic members, such as elastic materials such as coil springs and elastic rubbers, and it can also be arranged at a position between other locking members 174 and the pressing member 172.

[0054] Furthermore, in the present embodiment, the limiting member 173 is annular, and the limiting member 173 is opposite to the pressing hole 153, that is, the empty portion inside the limiting member 173 corresponds to the pressing hole 153, and at the same time, there are two locking members 174, the pressing member 172 and the two locking members 174 are all arranged in the limiting member 173, and the two locking members 174 are respectively arranged on the opposite sides of the pressing member 172, so that the two locking members 174 can more stably limit the connectivity state of the valve body 12, and the operator can simultaneously clamp the locking connection ends 1741 of the two opposite locking members 174 when resetting the valve body 12, which further facilitates the operator's operation.

[0055] Furthermore, a second locking portion 1744 is protruded from the locking connection end 1741 . The second locking portion 1744 is located on a side of the locking connection end 1741 away from the pressing end 1724 . That is, the second locking portion 1744 is protruded toward the limiting member 173 .

[0056] Furthermore, when the first locking portion 1743 abuts against the end face of the first limiting end 1731, the second locking portion 1744 can abut against the end face of the second limiting end 1732, which is the other end of the limiting member 173. In other words, when the end face of the first limiting end 1731 abuts against the locking end 1742, the second locking portion 1744 also abuts against the end face of the other end of the limiting member 173, thereby further and more stably maintaining the state of the valve body 12.

[0057] Furthermore, the valve body 12 also includes a reset elastic portion 121 and a valve core 122 and a switching portion 123 connected thereto, wherein the switching portion 123 is connected to the mounting side 151, the valve core 122 is connected to the push piece 172, and the valve core 122 can move relative to the switching portion 123 in a first direction or a second direction to switch the connectivity state of the valve body 12, and the reset elastic portion 121 is respectively connected to the valve core 122 and the switching portion 123, and enables the valve core 122 to have a tendency to move in a second direction opposite to the first direction. In other words, the valve core 122 has a tendency to reset under the action of the reset elastic portion 121.

[0058] By setting the reset elastic part 121, the damping of the operator pressing the pressing member 172 can be increased to avoid misoperation. The setting of the reset elastic part 121 also facilitates the automatic reset of the valve body 12 when the pressing member 172 and the locking member 174 are clamped, further improving the operational convenience of the emergency valve 10.

[0059] See also Figure 5 , Figure 5 A schematic diagram of the explosion structure of the emergency valve 10 provided in an embodiment of the present invention.

[0060] A guide connection portion 155 may be provided on the inner wall of the push hole 153, and a guide portion 1723 may be convexly provided on the side of the push member 172. The guide portion 1723 is slidably connected to the guide connection portion 155, and the guide connection portion 155 is arranged along the first direction, so that the guide portion 1723 can move relative to the guide connection portion 155 along the axial direction of the push hole 153. In this embodiment, the guide connection portion 155 is a protrusion convexly provided on the inner wall of the push hole 153 and has a sliding groove (not shown in the figure), and the guide portion 1723 is a protrusion matching the sliding groove. The guide portion 1723 is located in the sliding groove, and the sliding groove extends along the first direction, so that the guide portion 1723 slides in the sliding groove. In addition, in this embodiment, there are multiple pairs of guide connection portions 155 and guide portions 1723, which together enable the push member 172 to stably slide along the push hole 153.

[0061] See also Figure 5 and Figure 6 , Figure 6 A schematic cross-sectional structure diagram of the rotating shaft 192 of the emergency valve 10 provided in an embodiment of the present invention.

[0062] The emergency valve 10 also includes an outer cover assembly 19, which includes a sliding cover 191, a rotating shaft 192 and an annular cover body 193. The annular cover body 193 is connected to the operating side 152 and is opposite to the push hole 153. That is to say, the hollow portion of the cover body 193 corresponds to the push hole 153, and the sliding cover 191 and the cover body 193 are rotatably connected through the rotating shaft 192, and the axial direction of the rotating shaft 192 is parallel to the axial direction of the cover body 193. In other words, the sliding cover 191 can rotate relative to the cover body 193, and the rotating axis of the sliding cover 191 is parallel to the axis of the annular cover body 193. The sliding cover 191 can be rotated horizontally to one side of the cover body 193 to open the cover body 193, so that the operator can press the pressing member 172 on the operating side 152. The horizontal opening method requires less space and is not easy to interfere with the outward-opening sliding door body.

[0063] Furthermore, the outer cover assembly 19 may also include an alarm switch 194, which is used to activate the alarm of the vehicle. The alarm switch 194 is arranged on the cover body 193 and is opposite to the rotating shaft 192. When the sliding cover 191 rotates around the axis of the rotating shaft 192, the rotating rotating shaft 192 can trigger the alarm switch 194. In other words, the rotating rotating shaft 192 triggers the alarm switch 194, which is arranged near the shaft, is not prone to water ingress, aging and other problems, and is more stable in use.

[0064] It should be noted that, in the present embodiment, an eccentric wheel is provided on the rotating shaft 192, and the alarm switch 194 is arranged on the side of the rotating shaft 192. When the rotating shaft 192 rotates, the eccentric wheel is driven to rotate so as to approach or move away from the alarm switch 194, thereby triggering the alarm. In other embodiments, the rotating shaft 192 may also be a threaded shaft, and the alarm switch 194 is arranged at the bottom end of the threaded shaft. The threaded shaft can rotate with the sliding cover 191, and when the sliding cover 191 rotates, the threaded shaft moves relative to the cover body 193 along the axial direction of the cover body 193 to trigger the alarm switch 194.

[0065] Furthermore, a second limiting body 196 is provided on the cover body 193, and a first limiting body 195 is provided on the sliding cover 191. The second limiting body 196 corresponds to the first limiting body 195, and the second limiting body 196 can magnetically absorb the first limiting body 195, thereby maintaining the position of the sliding cover 191. It is not easy to rust, and can be arranged in the cover body 193 and the sliding cover 191 to maintain its stable function.

[0066] It should be noted that, in this embodiment, the first limiting body 195 is an iron sheet and the second limiting body 196 is a magnet. In other embodiments, one of the first limiting body 195 and the second limiting body 196 is a magnet and the other can be a magnet or other material that can be attracted to a magnet, or both are magnets.

[0067] Furthermore, a rain shield 197 is protruding from the edge of the cover body 193 along its axial direction and is located above the sliding cover 191. In other words, ribs are protruding from the edge of the cover body 193 to prevent rainwater from entering the valve body 12 on the operating side 152 or the installation side 151, thereby improving the stability of the emergency valve 10. In addition, a sealing strip 198 is provided on the side of the sliding cover 191 close to the cover body 193 to further prevent rainwater from entering the valve body 12 on the operating side 152 or the installation side 151, thereby improving the stability of the emergency valve 10.

[0068] The working principle of the emergency valve 10 provided in the embodiment of the present invention is:

[0069] The pressing assembly 17 includes a pressing member 172, a limiting member 173, a locking member 174 and a locking elastic member 175. The pressing member 172 is slidably connected to the base 15 for an operator to press. The limiting member 173 is installed on the base 15, and the locking member 174 is rotatably connected to the pressing member 172. The pressing member 172 can move relative to the base 15 along a first direction, and the first direction is the extension direction of the limiting member 173. Furthermore, the positioning member 174 is located between the limiting member 173 and the pressing member 172, and the positioning member 174 and the limiting member 173 are both extended along the first direction. In other words, the limiting member 173, the positioning member 174 and the pressing member 172 are arranged in sequence, and the three are all extended along the same direction. A first positioning portion 1743 is convexly provided on the side of the positioning member 174 away from the pressing member 172, or in other words, a first positioning portion 1743 is convexly provided on the side of the positioning member 174 close to the limiting member 173, and the first positioning portion 1743 is located between the limiting member 173 and the positioning member 174, and the positioning member 174 is provided with a first positioning portion 1743. The positioning elastic member 175 is arranged between the pressing member 172 and the locking member 174. The positioning elastic member 175 has an elastic force so that the first locking portion 1743 is abutted against the side of the limiting member 173, and the first locking portion 1743 has a tendency to turn to the limiting member 173. In other words, the positioning elastic member 175 exerts an elastic force to drive the locking member 174 to rotate, so that the first locking portion 1743 is abutted against the side of the limiting member 173 close to the locking member 174, and the part of the locking member 174 having the first locking portion 1743 has a tendency to turn to the limiting member 173. When the push member 172 moves along the first direction, or when the operator presses the push member 172 along the first direction, since the push member 172 is connected to the valve body 12, the push member 172 can switch the connectivity state of the valve body 12, and the push member 172 can also drive the first clamping portion 1743 to move along the side of the limiting member 173 and extend out of the first limiting end 1731, and make the first clamping portion 1743 abut against the end face of the first limiting end 1731 to maintain the above-mentioned connectivity state, wherein the first limiting end 1731 is one end of the limiting member 173. In other words, the locking member 174 moves along the first direction with the pressing member 172. Since the first locking portion 1743 abuts against the side of the limiting member 173 under the action of the locking elastic member 175, the first locking portion 1743 will move along the side of the limiting member 173. When the first locking portion 1743 just extends out of the first limiting end 1731, the first locking portion 1743 will also turn to the side of the limiting member 173 away from the locking member 174 under the action of the locking elastic member 175. At this time, the first locking portion 1743 protruding from the side of the locking member 174 away from the pressing member 172 will abut against the end face of the first limiting end 1731 to limit the pressing member 172 from moving in a second direction opposite to the first direction, thereby limiting the pressing member 172 from driving the valve body 12 again to maintain the connection state of the valve body 12.In this way, the operator can operate the valve body 12 by pressing or pulling the push member 172. The operation has low requirements for gripping, is more convenient, and avoids the phenomenon of difficult operation.
