Opening the doors can be extremely dangerous due to the wind, causing them to open too quickly or at too wide an angle, damaging the hinges and door limiters, making the doors unable to close or reopen. In extreme weather, the doors may detach from the vehicle, potentially causing a serious collision between the truck and the aircraft, or even lifting workers from the cockpit due to strong winds, resulting in injury.

[0046] This application provides a door limiting device, including a limiting component and a positioning component. Both the limiting component and the positioning component are assembled on the inner panel of the door, with the positioning component located above the limiting component. One end of the limiting component is connected to the vehicle body. The limiting component includes a limiting groove and multiple abutment grooves communicating with the limiting groove. The limiting groove is located on the side closer to the vehicle body relative to the multiple abutment grooves, and the multiple abutment grooves are interconnected and arranged side by side. The positioning component includes a driving member, a positioning component connected to the driving member, and an operating member connected to the positioning component. The driving member has a first state and a second state. When the driving member is in the first state, the positioning component is located above the limiting groove and separated from the limiting component. When the driving member switches from the first state to the second state, the driving member drives the positioning component, causing the positioning component to move downward relative to the driving member. When the driving member is in the second state, the positioning component is located in the limiting groove and abuts against the limiting groove. After the driving member is in the second state, the operating member is actuated, causing the positioning component to move from the limiting groove to one of the multiple abutment grooves, thereby opening the door relative to the vehicle body. The positioning element abuts against the abutting groove to lock the door relative to the body.
[0047] The vehicle door limiting device and vehicle provided in this application embodiment are configured with a limiting component and a positioning component. The limiting component has a limiting groove and multiple abutment grooves. The positioning component has a driving component, a positioning component connected to the driving component, and an operating component connected to the positioning component. Before opening the vehicle door, the driving component drives the positioning component to move from top to bottom, so that the positioning component is located in the limiting groove and abuts against the limiting groove. Then, by moving the operating component, the positioning component is moved from the limiting groove to one of the multiple abutment grooves, and the positioning component abuts against the abutment groove. In this way, the vehicle door is slowly opened and the vehicle door and the vehicle body are locked at the opening angle. This allows for flexible adjustment of the opening angle between the vehicle door and the vehicle body and locks the vehicle door and the vehicle body relative to each other, avoiding problems such as the vehicle door being unable to lock or being opened or closed quickly due to high external wind speed, which could cause damage to the vehicle door or injury to personnel.
[0048] The door limiting device and vehicle of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.
[0049] Figure 1 The diagram shown is an installation schematic of a door limiting device 10 according to an embodiment of this application. Figure 1 As shown, the vehicle equipped with the door limiting device 10 includes a body 12, a door 11 connected to the body 12, and the door limiting device 10. The door limiting device 10 includes a limiting component 20 and a positioning component 30. Both the limiting component 20 and the positioning component 30 are assembled on the inner panel of the door 11. The limiting component 20 of the door limiting device 10 is connected between the door 11 and the body 12. One end of the limiting component 20 is connected to the body 12, and the positioning component 30 is located above the limiting component 20.
[0050] The positioning component 30 is assembled to the inner panel of the door 11 via the fastener 13, and one end of the limiting component 20 is hinged to the side of the body 12 near the door 11 via the hinge 14. Because the door 11 needs to be rotated to open and close relative to the body 12, and the door 11 and the body 12 are hinged, one end of the limiting component 20 is hinged to the side of the body 12 near the door 11 to facilitate the limiting component 20 to rotate with the door 11 relative to the body 12.
[0051] The limiting component 20 is slidably disposed on the inner panel of the door 11. The inner panel of the door 11 is provided with a slide for the limiting component 20 to slide. The limiting component 20 can slide relative to the inner panel of the door 11 as the opening angle of the door 11 changes.
[0052] This configuration allows the limiting component 20 to adjust its extension distance from the door 11 as the distance between the positioning component 30 on the door 11 and the vehicle body 12 changes during the door opening process. When the door 11 is closed relative to the vehicle body 12, the limiting component 20 is located inside the door 11; as the opening angle of the door 11 relative to the vehicle body 12 increases, the length of the limiting component 20 extending from inside the door 11 also increases.
[0053] The positioning component 30 is located above the limiting component 20. This allows the positioning component 30 to control the distance the limiting component 20 extends from the door 11. The cooperation between the limiting component 20 and the positioning component enables the door 11 to be locked relative to the vehicle body 12, controls the opening speed and angle of the door 11, and protects the safety of the door 11 in abnormally windy conditions.
[0054] exist Figure 1 In the illustrated embodiment, the vehicle also includes an anemometer 15, which is located outside the vehicle body 12 and is used to monitor wind speed. Because excessive wind speed can cause the door 11 to open too quickly and at too large an angle, potentially damaging the hinges and limiters of the door 11, the ambient wind speed can be determined by the anemometer 15 located outside the vehicle body 12 before opening the door 11. The anemometer 15 can be a spiral anemometer or a radar anemometer, preferably a radar anemometer, as it utilizes the Doppler principle for wind speed measurement and offers high accuracy.
[0055] Figure 2 As shown Figure 1 The diagram shows the structure of the door limiting device 10; as shown. Figure 2 As shown, the limiting component 20 includes a limiting groove 21 and a plurality of abutting grooves 22 communicating with the limiting groove 21. The limiting groove 21 is located on the side closer to the vehicle body 12 relative to the plurality of abutting grooves 22. The plurality of abutting grooves 22 are interconnected and arranged side by side.
[0056] The positioning component 30 includes a driving member 31, a positioning member 32 connected to the driving member 31, and an operating member 33 connected to the positioning member 32. The driving member 31 has a first state and a second state. When the driving member 31 is in the first state, the positioning member 32 is located above the limiting groove 21 and is separated from the limiting component 20. When the driving member 31 switches from the first state to the second state, the driving member 31 drives the positioning member 32, causing the positioning member 32 to move from top to bottom relative to the driving member 31. When the driving member 31 is in the second state, the positioning member 32 is located inside the limiting groove 21 and abuts against the limiting groove 21.
[0057] When the drive member 31 is in the second state, the operating member 33 is actuated, causing the positioning member 32 to move from the limiting groove 21 into one of the multiple abutment grooves 22, thereby opening the door 11 relative to the body 12. The positioning member 32 abuts against the abutment groove 22 to lock the door 11 relative to the body 12.
[0058] The limiting groove 21 is positioned such that, when the door 11 is closed, the positioning member 32 in the positioning assembly 30 is located directly above the limiting groove 21. This arrangement ensures that, when the door is closed, as the drive member 31 switches from the first state to the second state, the drive member 31 drives the positioning member 32 to move downwards, causing it to fall into the limiting groove 21 and abut against it.
[0059] The limiting groove 21 is located at one end of the plurality of abutting grooves 22, and the size of the limiting groove 21 is larger than the size of the abutting groove 22. The size of the limiting groove 21 is larger than the size of the positioning member 32, so that when the positioning member 32 moves from top to bottom, it falls into the limiting groove 21.
[0060] In this embodiment, the door limiting device 10, when in use, with the drive member 31 in the first rotating state, the positioning component 30 on the door 11 is not connected to the limiting component 20 hinged to the body 12, allowing the door to open freely. When the drive member 31 is in the first state, the positioning component 32 in the positioning component 30 is located within the limiting groove 21 of the limiting component 20 and abuts against the limiting groove 21. At this time, the door and body are locked, and the door cannot be opened freely. In this state, by moving the operating member 33 of the positioning component 30, the positioning component 32 can be moved from the limiting groove 21 to one of the multiple abutting grooves 22, allowing the door 11 to open relative to the body 12.
[0061] The vehicle door limiting device 10 and vehicle provided in this application embodiment are configured with a limiting component 20 and a positioning component 30. The limiting component 20 is configured with a limiting groove 21 and multiple abutment grooves 22. The positioning component 30 is configured with a driving member 31, a positioning member 32 connected to the driving member 31, and an operating member 33 connected to the positioning member 32. Before the vehicle door 11 is opened, the driving member 31 drives the positioning member 32 to move from top to bottom, so that the positioning member 32 is located in the limiting groove 21 and abuts against the limiting groove 21. Then, by a toggle operation... The positioning component 32 moves from the limiting groove 21 to one of the multiple abutting grooves 22. The positioning component 32 abuts against the abutting groove 22, thus slowly opening the door 11 and locking the door 11 and the body 12 at the opening angle. This allows for flexible adjustment of the opening angle between the door 11 and the body 12, and locks the door 11 and the body 12 relative to each other. This prevents the door 11 from being unable to lock, or from opening or closing quickly due to excessive wind speed in the external environment, which could cause damage to the door 11 or injury to personnel.
[0062] Figure 1 In the illustrated embodiment, the vehicle includes an on-board controller 16 electrically connected to an anemometer 15. The on-board controller 16 is also electrically connected to a positioning component 30. When the anemometer 15 detects that the wind speed outside the vehicle body 12 has reached a wind speed threshold, the on-board controller 16 controls the positioning component 30 to switch the drive unit 31 from a first state to a second state. This configuration allows the on-board controller 16 to complete the switching of the drive unit 31 from the first state to the second state. Furthermore, the on-board controller 16 correlates the switching of the drive unit 31 from the first state to the second state with the wind speed detected by the anemometer 15, achieving an automated level of automation for opening the door limiting device 10. Automatic switching from the first state to the second state prevents staff from forgetting to detect the wind speed or operate the drive unit 31, thus avoiding the possibility of opening the door 11 directly when the door limiting device 10 is not working, which could cause abnormal door opening. The on-board controller 16 is movably mounted inside the vehicle body 12 and can be placed near the driver's side door 11 for easy operation by staff.
[0063] exist Figure 1 In the embodiment shown, when it is necessary to unlock the door 11 from the body 12, there are two unlocking methods. One unlocking method is to switch the drive member 31 from the second state to the first state, drive the positioning member 32, and make the positioning member 32 move from bottom to top relative to the drive member 31, so that the positioning member 32 is located above the limiting groove 21 and separates from the limiting component 20, so that the door 11 can be unlocked from the body 12 and the door 11 can be closed relative to the body 12.
[0064] With this setup, the door 11 and the body 12 can be quickly unlocked by operating the drive component 31, which can switch from the second state to the first state. The operation is simple and the unlocking efficiency is high. After unlocking using this method, the door 11 can be freely closed relative to the body 12 before the drive component 31 switches from the first state to the second state, and it can also be freely opened after closing.
[0065] When unlocking using this method, the vehicle controller 16 controls the positioning component 30, causing the drive unit 31 to switch from the second state to the first state. The vehicle controller 16 achieves this state switching of the drive unit 31, making the operation simple, efficient, and facilitating quick closing of the door 11. A reset button can be added to the vehicle controller 16, allowing the drive unit 31 to switch from the second state to the first state. Unlocking the door 11 from the vehicle body 12 requires only operation of the vehicle controller 16.
[0066] exist Figure 1 In the embodiment shown, when it is necessary to unlock the door 11 from the body 12, a second unlocking method can also be used. The operating member 33 is toggled to move the positioning member 32 from one of the abutting grooves 22 to the limiting groove 21, so that the positioning member 32 is unlocked from one of the abutting grooves 22, thereby unlocking the door 11 from the body 12 and allowing the door 11 to close relative to the body 12.
[0067] With this configuration, when the drive component 31 fails, or the vehicle controller 16 cannot control the drive component 31, the door 11 can be closed relative to the vehicle body 12 by toggling the operating component 33. This is applicable when the drive component 31 is damaged or fails, and it is impossible to switch from the second state to the first state, serving as a backup door-closing method in case the drive component 31 is damaged. Alternatively, it can be used when the external wind speed of the vehicle body 12 is too high, requiring a limitation on the closing speed of the door 11 to prevent the door 11 from closing too quickly.
[0068] In some alternative embodiments, the vehicle also includes a repellent device that emits sound waves of a certain frequency to repel birds and insects, preventing them from interfering with refueling. The repellent device is electrically connected to the on-board controller 16, which is used to be in an open state after the vehicle stops. When the repellent device is in the open state, the on-board controller 16 is used to drive and control the anemometer 15 to operate.
[0069] According to the refueling operation procedure, before opening door 11 to refuel, the operator must first stop the vehicle, engage the parking brake switch, and then disengage the clutch. Only then can they open door 11 to exit the vehicle for refueling. Therefore, according to the refueling operation procedure, the clutch switch must be in the open position before opening door 11. Making the clutch switch open a prerequisite for the operation of the anemometer 15 not only ensures that wind speed measurement has been performed before opening door 11, but also avoids energy waste caused by the anemometer 15 performing wind speed measurements for an extended period when door 11 is not needed. Furthermore, when door 11 is not needed, the drive component 31 in the door limiting device 10 can be in either the first or second state. Therefore, the door limiting device 10 can be temporarily inactive when door 11 is not needed. Thus, by keeping the door limiting device 10 in an inactive state before opening the clutch switch, energy consumption can be reduced and the service life of the door limiting device 10 can be extended.
[0070] In some embodiments, after the drive unit 31 switches from the second state to the first state, the vehicle controller 16 controls the anemometer 15 to stop working. When the drive unit 31 switches from the second state to the first state, the door 11 and the body 12 are unlocked, and the door 11 can be opened and closed freely. At this time, it is no longer necessary to measure the wind speed, and the vehicle controller 16 controls the anemometer 15 to stop measuring the wind speed.
[0071] exist Figure 2 In the illustrated embodiment, the limiting component 20 includes a hollow limiting frame 23 and a plurality of limiting teeth 24 disposed on the limiting frame 23. The plurality of limiting teeth 24 are arranged in pairs, and each pair of limiting teeth 24 is disposed opposite to the inner sidewall of the limiting frame 23. Two adjacent limiting teeth 24 and the inner sidewall of the limiting frame 23 enclose each other to form an abutment groove 22. In the direction in which the plurality of limiting teeth 24 are arranged, the limiting teeth 24 that are closer to the vehicle body 12 and located at the end have a limiting groove 21 on the side facing the vehicle body 12.
[0072] The limiting groove 21 provides an initial accommodating space for the positioning member 32 to move downwards into the limiting frame 23. Among them, in the direction in which the multiple limiting teeth 24 are arranged, the limiting teeth 24 that are away from the body 12 and located at the end have an anti-detachment groove 25 on the side facing away from the body 12. The anti-detachment groove 25 limits the maximum opening angle of the door 11. When the door 11 is opened to the preset maximum angle, the positioning member 32 is located in the anti-detachment groove 25. The anti-detachment groove 25 can prevent the positioning component 30 from disengaging from the limiting component 20 after the door 11 is opened to the maximum angle.
[0073] exist Figure 1 and Figure 2In the illustrated embodiment, the positioning component 30 includes a solenoid valve, which includes a valve body, an electromagnetic coil disposed within the valve body, and a valve core 34 disposed within the valve body and electrically connected to the electromagnetic coil. The driving component 31 includes an electromagnetic coil, and the positioning component 32 includes the valve core 34. The electromagnetic coil has an energized state and an de-energized state.
[0074] Solenoid valves are electromagnetically controlled industrial devices. They can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. Solenoid valves can be classified into normally closed and normally open solenoid valves. In a normally open solenoid valve, when the solenoid coil is energized, it generates electromagnetic repulsion, causing the valve core 34 to move downwards and press against the valve seat, thus closing the valve. When the coil is de-energized, the spring force lifts the valve core 34 from the valve seat, opening the valve. The normally closed solenoid valve operates in the opposite manner.
[0075] In this embodiment, the solenoid valve is a normally open solenoid valve. When the solenoid coil is energized, the valve core 34 moves downward; when the solenoid coil is de-energized, the valve core 34 moves upward. The change in the energized or de-energized state of the solenoid coil can be controlled by the vehicle controller 16, which is electrically connected to the positioning assembly 30. The vehicle controller 16 controls the switching of the energized or de-energized state of the solenoid coil by controlling the power supply to the drive component 31 within the positioning assembly 30, thereby controlling the movement direction of the valve core 34. This method is simple to operate, has high control precision, and offers flexible control methods.
[0076] In this embodiment, a normally open solenoid valve is used. When the door 11 does not need to be opened and when the opening speed of the door 11 does not need to be limited in normal weather, the solenoid coil is not energized. The solenoid coil is only energized when the door needs to be opened, and when the opening speed of the door 11 needs to be limited in windy weather, causing the positioning member 32 to move downwards into the limiting groove 21. This design reduces the duration of energizing the solenoid coil, saving energy and preventing the solenoid coil from overheating.
[0077] When the electromagnetic coil is de-energized, the valve core 34 is located above the limiting groove 21 and separated from the limiting component 20. At this time, the limiting component 20 cannot act on the positioning component 30 and cannot control the distance of the limiting component 20 extending out of the vehicle body 12. At this time, the door 11 and the vehicle body 12 are in an unlocked state and the door can be opened freely.
[0078] When the electromagnetic coil switches from the de-energized state to the energized state and is in the energized state, the electromagnetic coil drives the valve core 34 to move from top to bottom relative to the valve body into the limiting groove 21. When the valve core 34 is in the limiting groove 21, the bottom of the valve core 34 and the pair of limiting teeth 24 at the end abut against the side wall of the limiting groove 21. At this time, the limiting component 20 cannot move relative to the positioning component 30. The positioning component 30 controls the distance of the limiting component 20 extending out of the vehicle body 12, thereby locking the door 11 relative to the vehicle body 12. At this time, the door 11 is in the closed state and cannot be opened.
[0079] After the electromagnetic coil is energized, the operating component 33 is moved to move the valve core 34 from the limiting groove 21 to one of the multiple abutting grooves 22, so that the bottom of the valve core 34 abuts against the side walls of the two adjacent limiting teeth 24 and the inner side wall of the limiting frame 23, so that the door 11 opens relative to the body 12 and locks relative to the body 12.
[0080] This configuration allows the door 11 to open slowly relative to the body 12 and be fixed at the opening angle. When it is necessary to change the opening angle of the door 11, the operating component 33 is moved again, causing the valve core 34 to move from the current abutment groove 22 to another abutment groove 22, and the bottom of the valve core 34 to abut against the side wall of the other two adjacent limiting teeth 24 and the inner side wall of the limiting frame 23, thereby realizing the change and locking of the opening angle of the door 11 relative to the body 12.
[0081] Figure 3 The diagram shown is a schematic diagram of the valve core 34 of the door limiting device 10 according to an embodiment of this application. Figure 4 As shown Figure 3 A schematic diagram of one state of the valve core 34 shown. Figure 5 As shown Figure 3 A schematic diagram showing another state of the valve core 34. (As shown) Figures 3 to 5 As shown, the valve core 34 includes a magnetic sleeve 341, a magnetic positioning post 342 disposed within the magnetic sleeve 341, a positioning sleeve 343 sleeved around the magnetic positioning post 342, a return spring sleeved between the magnetic positioning post 342 and the positioning sleeve 343, and a positioning tooth 344 disposed at the bottom of the magnetic positioning post 342. The positioning tooth 344 includes a positioning post 345 and abutment teeth 346 disposed around the positioning post 345. The positioning post 345 is coaxially connected to the magnetic positioning post 342.
[0082] exist Figures 3 to 5In this embodiment, the operating member 33 includes an operating handle, which is located outside the positioning post 345, partially at the bottom of the positioning sleeve 343 and extending to the outside of the magnetic sleeve 341. The positioning sleeve 343 has a notch 35 at a preset angle. A limiting part 347 is provided on one side of the magnetic positioning post 342. The limiting part 347 is located inside the notch 35 and abuts against one edge of the notch 35. This edge is... Figure 4 The first edge 351 is shown. The limiting portion 347 abuts against the positioning tooth 344 in the vertical direction. The positioning tooth 344 can provide support for the limiting portion 347, increasing the stability of the limiting portion 347.
[0083] Moving the operating handle causes the magnetic positioning post 342 to rotate within the positioning sleeve 343 via the positioning post 345. This causes the limiting part 347 to rotate relative to the notch 35 within the notch 35 and to abut against another edge of the notch 35. This edge is... Figure 4 The second edge 352 is shown. At this time, the valve core 34 moves from... Figure 4 The state shown is transformed into Figure 5 The state shown.
[0084] When the valve core 34 is located in the limiting groove 21, the positioning tooth 344 abuts against the side wall of the limiting groove 21. When the valve core 34 is located in the abutting groove 22, the positioning tooth 344 is located between the side walls of two adjacent limiting teeth 24 and abuts against the inner side wall of the limiting frame 23, so that the door 11 opens relative to the body 12 and locks relative to the body 12.
[0085] This configuration makes the magnetic positioning post 342 and the positioning tooth 344 at the bottom of the magnetic positioning post 342 a whole. When the operating handle is turned, the magnetic positioning post 342 is rotated in the positioning sleeve 343 through the positioning post 345. When the magnetic positioning post 342 rotates relative to the positioning sleeve 343, it can drive the positioning tooth 344 located at the lower part of the magnetic positioning post 342 to rotate.
[0086] The rotation of the positioning tooth 344 reduces the projected length of the abutment tooth 346 in the width direction of the limiting frame 23, releasing the abutment of the positioning tooth 344 in the abutment groove 22 or the limiting groove. The positioning tooth 344 enters the channel composed of multiple opposing limiting teeth 24 in the limiting frame 23 and rotates into another abutment groove 22. The positioning tooth 344 is located between the side walls of two adjacent limiting teeth 24 and abuts against the inner side wall of the limiting frame 23, realizing the movement and locking of the limiting component 20 relative to the positioning component 30, so that the door 11 opens relative to the body 12 and locks relative to the body 12.
[0087] The abutment teeth 346 and the operating handle are located on opposite sides of the positioning post 345. For ease of operation, when the operating handle is not rotated, the abutment teeth 346 are located on the side of the positioning post 345 closest to the door 11, and the operating handle is located on the side of the positioning post 345 closest to the staff position inside the vehicle. Whether closing or opening the door by moving the operating handle, the handle is moved clockwise, causing the positioning post 345 and the magnetic positioning post 342 to rotate counterclockwise from the side of the door 11 towards the vehicle body 12. This causes the limiting part 347 to change from abutting against the first edge 351 of the positioning sleeve 343 to abutting against the second edge 352 of the positioning sleeve 343, allowing it to enter... Figure 5 The valve core shown is in a state that releases the current locking groove 22 or the limiting groove 21 from the positioning tooth 344, which is consistent with the habit of rotating clockwise when manually moving an object.
[0088] The center angle corresponding to the notch 35 is at least 90°, and the limiting part 347 rotates at least 90° within the notch 35. The limiting part 347 can rotate at least 90°, that is, the positioning post 345 and the abutting teeth 346 provided on the periphery of the positioning post 345 can rotate at least 90°. The abutting teeth 346 can rotate from the direction perpendicular to the length of the limiting frame 23 to the direction parallel to the length of the limiting frame 23, thereby releasing the abutting groove 22 where the positioning teeth 344 are located from the positioning teeth 344.
[0089] The center angle corresponding to the notch 35 is the maximum angle that the limiting part 347 can rotate within the notch 35. If the center angle corresponding to the notch 35 is set too large, the length of the return spring sleeved between the magnetic positioning post 342 and the positioning sleeve 343 will become smaller, and the angle of rotation of the magnetic positioning post 342 within the notch 35 will become larger, which will cause the deformation of the return spring to become larger, which is not conducive to the reset of the return spring.
[0090] The abutment tooth 346 can rotate 90° to move from a direction perpendicular to the length of the limiting frame 23 to a direction parallel to the length of the limiting frame 23, entering the channel formed by multiple opposing limiting teeth 24 within the limiting frame 23. This releases the abutment of the positioning tooth 344 in the abutment groove 22 or the limiting groove 21, allowing the positioning tooth 344 to rotate and enter another abutment groove 22 adjacent to the abutment groove 22 or the limiting groove 21. If the center angle corresponding to the notch 35 is set too large, the rotation angle of the abutment tooth 346 will be too small, which will either hinder the release of the abutment of the positioning member 32 in the abutment groove 22 or the limiting groove 21, making it impossible to unlock the door 11 at a fixed angle relative to the body 12. If the abutment of the positioning tooth 344 in the abutment groove 22 or the limiting groove 21 can be released by simply rotating a small angle, it indicates that the channel composed of multiple relatively arranged limiting teeth 24 in the limiting frame 23 is too large relative to the diameter of the positioning post 345, which is not conducive to the abutment stability when the door 11 and the body 12 are locked.
[0091] One end of the return spring is connected to the magnetic positioning post 342, and the other end is connected to the positioning sleeve 343. When the operating handle is not turned, the limiting part 347 abuts against one side of the notch 35, that is, the first edge 351 abuts against it, at which time the valve core 34 is in position. Figure 4 The state shown is as follows. Rotating the operating handle causes the magnetic positioning pin 342 to rotate within the positioning sleeve 343 via the positioning pin 345. During rotation, the return spring is stretched and stores force. When the limit part 347 abuts against the other side of the notch 35, that is, against the second edge 352, the valve core 34 is in the position shown. Figure 5 The state shown.
[0092] The positioning pin 345 and the magnetic positioning pin 342 can no longer rotate, releasing the contact between the positioning tooth 344 and the abutment groove 22 or the limiting groove 21. At this time, the positioning tooth 344 moves from one abutment groove 22 or the limiting groove 21 to another abutment groove 22. Releasing the operating handle causes the magnetic positioning part to rotate in the reverse direction under the elastic deformation and stored force of the return spring, at which point the valve core 34 returns to its original position. Figure 4 The state shown allows the positioning tooth 344 to abut against another abutment groove 22, achieving relative locking between the door 11 and the body 12.
[0093] The limiting component 20 is made of carbon steel. Within the limiting component 20, the limiting frame 23 and the limiting teeth 24 are also made of carbon steel. The hinge 14, which is hinged to the limiting component 20 at one end and fixedly connected to the door 11 at the other end, is also made of carbon steel. In the positioning component 30, the positioning teeth 344, the operating handle, the magnetic positioning post 342, and the positioning sleeve 343 are all made of carbon steel.
[0094] Carbon steel is an iron-carbon alloy with a carbon content ranging from 0.0218% to 2.11%, also known as carbon steel. It typically also contains small amounts of silicon, manganese, sulfur, and phosphorus. The heat treatment process during carbon steel processing gives it high strength and rigidity, enabling it to withstand greater pressure and load. The carbon content also increases surface hardness, effectively resisting friction and wear. This design allows the limiting component 20 and the positioning component 30 to withstand greater forces while reducing wear and extending the service life of the door limiting device 10.
[0095] exist Figure 2 In the illustrated embodiment, the abutting tooth 346 has a bevel 348 on one side of the limiting groove 21, and each limiting tooth 24 has a chamfer 241 on the side away from the limiting groove 21. The inclination angle of the chamfer 241 is the same as the inclination angle of the bevel 348. The abutting tooth 346 has a bevel 348, and the limiting tooth 24 has a chamfer 241. The bevel 348 is located on one side of the limiting groove 21, and the chamfer 241 is located on the side away from the limiting groove 21, that is, on the side opposite to the adjacent bevel 348.
[0096] By setting the inclined surface 348 and the chamfer 241, when closing the car door 11 by moving the operating handle, it is only necessary to move the operating handle to unlock the positioning tooth 344 from one of the abutting grooves 22. After unlocking, the positioning tooth 344 can move smoothly to the limiting groove 21 through the inclined surface 348 and the chamfer 241, at which point the car door 11 can be closed.
[0097] Each limiting tooth 24 has a chamfer 241 on the side away from the limiting groove 21, and the inclination angle of the chamfer 241 ranges from 30° to 60°. In some embodiments, the inclination angle of the chamfer 241 can be 30°, 45°, or 60°, preferably 45°. This setting facilitates the processing of the chamfer 241 and does not affect the strength of the limiting tooth 24 after the chamfering process. Furthermore, if the angle of the chamfer 241 is too small, when closing the car door 11, the unlocked positioning tooth 344 will not easily move out of the current abutment groove 22, resulting in the inability to close the car door 11. If the angle of the chamfer 241 is too large, when opening the car door 11, the abutment groove 22 will not easily abut and fix the positioning tooth 344, resulting in poor locking effect of the car door limiting device 10.
