Abstract
Description
Technical Field
[0001] The present application relates to the field of vehicle technology, and in particular to a resetting mechanism, a seat and a vehicle. Background Art
[0002] With the improvement of living standards, cars have become the main means of transportation for people to travel. Generally, there are several seats in the car for passengers to sit. The role of seats in the car is very important and is related to the comfort and safety of passengers.
[0003] In order to allow passengers to drive and ride in the most comfortable state, many cars will set zero gravity mode for the seats to relieve passengers' fatigue during the journey. And passengers can choose to switch the seat mode by themselves. At present, the seats mainly rely on the transmission of the motor-driven screw rod to control the seat switching mode.
[0004] When the vehicle is hit from outside, the seat needs to be quickly switched to a normal sitting position to ensure the safety of the passengers. However, the speed of switching the seat mode through the above adjustment method is relatively slow. Utility Model Content
[0005] The embodiments of the present application provide a reset mechanism, a seat, and a vehicle for solving the problem that existing seats cannot quickly switch from a zero-gravity mode to a normal sitting mode.
[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:
[0007] On the one hand, an embodiment of the present application provides a reset mechanism for being installed on a seat to realize the conversion of the seat between a zero gravity state and a normal state. The reset mechanism includes a reset assembly, a drive assembly and a brake assembly. The reset assembly includes a fixed member, a sliding member and a locking member. The fixed member and the sliding member are slidably connected. The locking member is used to lock or unlock the relative sliding between the fixed member and the sliding member. The drive assembly includes a drive motor and a screw. One end of the screw is threadedly connected to the sliding member, and the other end is connected to the output end of the drive motor. The brake assembly is connected to the reset assembly, and is used to enable the locking member to unlock the fixed member and the sliding member and push the sliding member to slide when the vehicle is hit.
[0008] The reset mechanism provided in the embodiment of the present application is such that when the vehicle is in a normal state, the passenger can switch the seat from the normal sitting mode to the zero gravity mode by operating the drive assembly. Conversely, the seat can also be switched from the zero gravity mode to the normal sitting mode. When the car is hit by an external impact, the external impact force will act on the seat, causing the brake assembly to start. The brake assembly acts on the reset assembly, and the locking member in the reset assembly unlocks the fixed member and the sliding member, and the sliding member can drive the screw rod and the drive motor to slide relative to the fixed member. At this time, the sliding member slides relative to the fixed member under the action of the power generated by the brake assembly until the reset mechanism can switch the state of the seat from the zero gravity mode to the normal sitting mode.
[0009] In some embodiments, the interior of the fixing member is hollow, and has openings at both ends. The sliding member is located inside the fixing member and is slidably connected to the fixing member. The locking member is located inside the fixing member. The driving assembly is located at the opening at one end of the fixing member, and the braking assembly is located at the opening at the other end of the fixing member.
[0010] In some embodiments, the brake assembly includes a sealing member and an airbag assembly. The sealing member is connected to the opening at the other end of the fixing member to seal the opening at the other end of the fixing member. The airbag assembly is arranged inside the fixing member and located at one end of the sliding member.
[0011] In some embodiments, the interior of the fixing member includes a first hole segment and a second hole segment that are connected to each other. The second hole segment is located on a side of the first hole segment close to the drive assembly, and the aperture of the second hole segment is larger than the aperture of the first hole segment. The reset assembly also includes a limiter. The limiter is installed at the opening at one end of the fixing member, covering the opening at one end of the fixing member. The limiter is provided with an avoidance hole. Among them, the sliding member is inserted into the avoidance hole. A blocking portion is formed on the peripheral wall of the sliding member. The blocking portion is located in the second hole segment. At least a portion of the projection of the blocking portion on the plane where the orifice of the first hole segment is located is located outside the first hole segment, and at least a portion of the projection of the blocking portion on the plane where the orifice of the avoidance hole is located is located outside the avoidance hole.
[0012] In some embodiments, the inner wall of the fixing member has a first limiting groove, the peripheral wall of the sliding member has a second limiting groove, and the locking member is used to be arranged in the first limiting groove and the second limiting groove to lock the fixing member and the sliding member.
[0013] In some embodiments, a mounting groove is provided at one end of the sliding member close to the brake assembly. The second limiting groove is connected to the mounting groove. The reset assembly further includes a receiving member, which is slidably connected to the mounting groove. The receiving member has a bearing groove on its surface close to the first limiting groove. The locking member is used to be arranged in the second limiting groove and the bearing groove to unlock the fixing member and the sliding member.
[0014] In some embodiments, the inner wall of the fixing member further has a third limiting groove. Along the sliding direction of the sliding member, the third limiting groove is spaced apart from the first limiting groove. The reset assembly further includes an elastic member. The elastic member is located in the installation groove, on the side of the receiving member close to the groove bottom of the installation groove. One end of the elastic member is connected to the groove bottom of the installation groove, and the other end is connected to the receiving member.
[0015] In some embodiments, the elastic member is a spring.

[0017] On the other hand, an embodiment of the present application further provides a vehicle, comprising the above-mentioned seat.
[0018] Since the seat and vehicle provided in the embodiments of the present application include any one of the above-mentioned reset mechanisms, the beneficial effects that can be produced by the above-mentioned seat and vehicle are the same as the beneficial effects of the above-mentioned reset mechanism, which will not be repeated here.

DETAILED DESCRIPTION
[0028] The embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0029] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0030] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.
[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0032] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0033] With the development of automobile manufacturing technology and economy, the usage rate of automobiles in people's lives is getting higher and higher. At the same time, more and more people are beginning to pay attention to the functional experience when riding in a car.
[0034] When passengers are in a car, the first thing they feel is whether the car seat is comfortable. And the comfort of the seat determines the comfort of the entire journey to a certain extent. Therefore, in order to make passengers have a more comfortable experience during the journey, some manufacturers have developed a zero-gravity mode for the seat.
[0035] When passengers adjust the seat to zero-gravity mode, the seat changes its own mechanical structure and control system, allowing passengers to raise their legs and position their body at a more comfortable angle, thereby reducing back pressure, improving blood circulation, and enhancing comfort. At the same time, many seats with zero-gravity mode also have memory and quick reset functions, which can be personalized according to personal needs and easily switch between different usage modes.
[0036] In the related art, the seat mainly relies on a motor-driven screw transmission to control the seat switching mode. However, the switching speed using this method is slow, and the seat cannot be quickly switched from zero gravity mode to normal sitting mode when necessary, thus affecting the passenger's operation and safety.
[0037] Based on this, an embodiment of the present application provides a vehicle, wherein the vehicle provided in the embodiment of the present application can be different types of vehicles. For example, the vehicle can be a fuel vehicle or a new energy vehicle.
[0038] The vehicle may include basic structures such as the engine, chassis and body. The body is the outer shell and internal space structure of the upper part of the vehicle, providing space for passengers and cargo. The body may specifically include components such as the frame, doors, windows, front panels, fenders, trunk lid, engine hood, etc., as well as interior parts such as the dashboard, seat belts, air conditioning system, audio and entertainment system, etc.
[0039] The vehicle may include seats. Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a seat 100 provided in an embodiment of the present application. The seat 100 can actively and passively switch between a zero gravity mode and a normal sitting mode.
[0040] The seat 100 in zero gravity mode can put the passenger's body in a more comfortable posture, significantly reducing muscle tension and fatigue during long-distance travel or long-term sitting. The seat 100 in normal sitting mode can relatively well protect the safety of the passenger and facilitate the passenger to control the vehicle.
[0041] The seat 100 plays a vital role in the car. It is not only related to the comfort of the passengers, but also an important part affecting driving safety. The seat 100 can provide sufficient support for the passengers so that the passengers can maintain a stable sitting position during the driving of the vehicle. The seat 100 can also absorb part of the impact force when the vehicle is hit by an external impact, and firmly fix the passengers on the seat 100 to prevent them from rushing forward or being thrown out of the vehicle due to inertia, thereby reducing the risk of injury.
[0042] like Figure 2 As shown, Figure 2 The seat 100 ( Figure 1 ), the seat 100 provided in the embodiment of the present application may include a reset mechanism 10. The reset mechanism 10 can adjust the state of the seat 100 by regulating its own state, so that the state of the seat 100 is switched between the zero gravity mode and the normal sitting mode, so as to meet the needs of passengers.
[0043] Among them, the reset mechanism 10 can make the seat 100 ( Figure 1 ) quickly switches from zero-gravity mode to normal sitting mode to protect the safety of passengers or enable passengers to immediately control the vehicle.
[0044] For example, Figure 2 and Figure 3 As shown, Figure 3 The seat 100 ( Figure 1 ), the seat 100 may also include a seat support 20, a seat basin rear connecting rod 30, a seat basin side plate 40, a slide rail support 50, a front connecting rod 60, a reset connecting rod 70 and a support member 80. Among them, the positions of the seat basin rear connecting rod 30, the seat basin side plate 40 and the slide rail support 50 are fixed relative to the seat support 20.
[0045] Among them, Figure 2 As shown, the seat basin side plate 40 is fixedly connected to the seat bracket 20, the seat basin rear connecting rod 30 is rotatably connected to the seat basin side plate 40 and the slide rail bracket 50 respectively, one end of the slide rail bracket 50 is rotatably connected to the seat basin side plate 40, and the other end is rotatably connected to the reset connecting rod 70, and the slide rail bracket 50 is also rotatably connected to the reset mechanism 10. One end of the reset mechanism 10 is rotatably connected to the slide rail bracket 50, and the other end is connected to the reset connecting rod 70.
[0046] One end of the front link 60 is rotatably connected to the reset link 70 , and the other end is rotatably connected to the support member 80 , while the other end of the support member 80 is rotatably connected to the seat basin side panel 40 .
[0047] When the length of the reset mechanism 10 becomes longer, because the position of the slide rail bracket 50 connected to one end thereof is fixed relative to the seat bracket 20 , the reset mechanism 10 moves away from the slide rail bracket 50 , driving the reset link 70 connected thereto to rotate toward the side away from the slide rail bracket 50 .
[0048] When one side of the reset link 70 rotates, it can drive one end of the front link 60 to rotate, so that the other end of the front link 60 rotates around its one end, further driving the support member 80 to rotate. At this time, the rotation of the support member 80 will reduce its own height, so that the height of the seat bracket 20 close to the reset link 70 is reduced, so that the seat 100 is converted from the zero gravity mode to the normal sitting mode.
[0049] Correspondingly, when the length of the reset mechanism 10 becomes shorter, the reset mechanism 10 can drive the reset link 70 to rotate, thereby driving the front link 60 and the support member 80 to rotate. At this time, the support member 80 will increase its own height due to the rotation, so that the height of the seat bracket 20 close to the reset link 70 side increases, so that the seat 100 is converted from the normal sitting mode to the zero gravity mode.
[0050] The reset mechanism 10 provided in the embodiment of the present application is installed on the seat 100 ( Figure 1 ) is used to realize the conversion of the seat 100 between the zero gravity state and the normal state. Figure 4 As shown, Figure 4 This is one of the partial structural sectional views of the reset mechanism provided in the embodiment of the present application. The reset mechanism 10 includes a reset assembly 11, a drive assembly 12 and a brake assembly 13.
[0051] The reset assembly 11 comprises a fixing member 111, a sliding member 112 and a locking member 113. The fixing member 111 and the sliding member 112 are slidably connected.
[0052] The locking member 113 is used to lock or unlock the relative sliding between the fixing member 111 and the sliding member 112. When the locking member 113 locks the fixing member 111 and the sliding member 112, the sliding member 112 cannot slide relative to the fixing member 111.
[0053] The driving assembly 12 includes a driving motor 121 and a screw rod 122. One end of the screw rod 122 is threadedly connected to the sliding member 112, and the other end is connected to the output end of the driving motor 121.
[0054] For example, Figure 4 and Figure 5 As shown, Figure 5The exploded schematic diagram of the structure of the reset mechanism 10 provided in the embodiment of the present application shows that the drive motor 121 in the drive assembly 12 can be rotatably connected to the reset link 70, and the fixing member 111 can be rotatably connected to the slide rail bracket 50. In this way, when the length of the reset mechanism 10 changes, the position of one side of the fixing member 111 in the reset mechanism 10 will not change, while one side of the drive motor 121 will be extended or shortened, thereby driving the reset link 70 to rotate.
[0055] like Figure 4 As shown, the brake assembly 13 is connected to the reset assembly 11 , and is used to enable the locking member 113 to unlock the fixing member 111 and the sliding member 112 and push the sliding member 112 to slide when the vehicle is hit.
[0056] When the car seat 100 is in a normal sitting position, the length of the reset mechanism 10 is relatively long. The passenger can actively manipulate the drive assembly 12 to make the drive motor 121 drive the screw rod 122 to rotate. At this time, the fixing member 111 and the sliding member 112 are relatively fixed under the action of the locking member 113. When the screw rod 122 rotates, the sliding member 112 will not slide relatively. Therefore, the screw rod 122 can control the reduction or increase of the overall length of the reset mechanism 10 by rotating with the sliding member 112, so that the reset mechanism 10 drives the seat 100 to switch back and forth between the zero gravity mode and the normal sitting position mode.
[0057] like Figure 4 As shown, when the screw rod 122 is completely screwed into the sliding member 112 through the threaded hole, the overall length of the reset mechanism 10 is reduced. At this time, the seat 100 ( Figure 1 When the screw rod 122 rotates in a direction away from the brake assembly 13, the overall length of the reset mechanism 10 becomes longer, and the reset mechanism 10 drives the seat 100 to adjust to the normal sitting posture mode until the mode of the seat 100 is adjusted to the normal sitting posture mode.
[0058] Therefore, the passenger can switch the seat 100 from the normal sitting mode to the zero gravity mode by operating the drive assembly 12. Figure 1 ) Switch from zero gravity mode to normal sitting mode.
[0059] like Figure 6 and Figure 7 As shown, Figure 6 The second cross-sectional view of the partial structure of the reset mechanism provided in the embodiment of the present application, Figure 7 The third cross-sectional view of the partial structure of the reset mechanism provided in the embodiment of the present application, when the car is hit by an external impact, the external impact force will act on the seat 100 ( Figure 1) on the reset assembly 11, so that the brake assembly 13 is activated. The brake assembly 13 acts on the reset assembly 11, and the locking member 113 in the reset assembly 11 unlocks the fixed member 111 and the sliding member 112, and the sliding member 112 can drive the screw rod 122 and the drive motor 121 to slide relative to the fixed member 111. At this time, the sliding member 112 slides relative to the fixed member 111 under the power generated by the brake assembly 13 until the reset mechanism 10 can switch the state of the seat 100 from the zero gravity mode to the normal sitting mode. In this way, the seat 100 can be quickly switched from the zero gravity mode to the normal sitting mode in an emergency.
[0060] In some embodiments, Figure 4 As shown, the interior of the fixing member 111 may be hollow, with openings at both ends. The sliding member 112 is located inside the fixing member 111 and is slidably connected to the fixing member 111. The locking member 113 is located inside the fixing member 111. The driving assembly 12 is located at the opening at one end of the fixing member 111, and the braking assembly 13 is located at the opening at the other end of the fixing member 111.
[0061] The hollow inside of the fixing member 111 can form an accommodation space for accommodating the sliding member 112 and the locking member 113, providing them with operating space, so that the sliding member 112 can achieve sliding connection with the fixing member 111. In addition, the driving component 12 and the braking component 13 are respectively located at both ends of the opening of the fixing member 111, and the position distribution is relatively reasonable, and there will be no conflict in the position.
[0062] The sliding member 112 and the locking member 113 are both located inside the fixing member 111 , so that the fixing member 111 can provide a certain degree of protection to the sliding member 112 and the locking member 113 , so that the movement of the sliding member 112 and the locking member 113 are not affected by the outside world.
[0063] In some embodiments, Figure 4 As shown, the brake assembly 13 may include a sealing member 131 and an airbag assembly. The sealing member 131 is connected to the opening at the other end of the fixing member 111 to seal the opening at the other end of the fixing member 111. The airbag assembly is arranged inside the fixing member 111 and located at one end of the sliding member 112.
[0064] When the brake assembly 13 is activated, the airbag assembly inside the fixing member 111 will expand rapidly, thereby generating a strong airflow. Since the seal 131 seals the opening at the other end of the fixing member 111, the airflow can only flow in the direction away from the seal 131, thereby exerting a force on the object it contacts, that is, on the sliding member 112 to move in the direction away from the brake assembly 13, so that the sliding member 112 moves rapidly in the direction away from the brake assembly 13. In this way, the reset mechanism 10 can drive the seat 100 ( Figure 1 )Quickly switch from zero gravity mode to normal sitting mode.
[0065] The seal 131 can seal the space inside the fixing member 111, preventing the airflow from leaking out of the seal 131, thereby reducing the pressure of the airflow. At the same time, the seal 131 can also prevent the device disposed inside it from being separated during movement, thereby ensuring the stability of the operation of the reset mechanism 10.
[0066] Exemplarily, the brake assembly 13 may include an explosive device. When the vehicle is hit or impacted, external force is applied to the seat 100. Then, this force acts on the seat 100 ( Figure 1 ) in the detonator, the detonator will immediately detonate after receiving the signal, causing the airbag assembly to expand rapidly and generate a rapid and powerful airflow. The airflow will push the sliding member 112 to move toward the side away from the brake assembly 13, causing the sliding member 112 to slide relative to the fixing member 111. Thus, the reset mechanism 10 drives the seat 100 to switch the seat 100 from the zero gravity mode to the normal sitting mode.
[0067] In some embodiments, Figure 4 As shown, the interior of the fixing member 111 may include a first hole section 11101 and a second hole section 11102 connected to each other. The second hole section 11102 is located on a side of the first hole section 11101 close to the driving assembly 12, and the aperture of the second hole section 11102 is larger than that of the first hole section 11101.
[0068] The reset assembly 11 may further include a stopper 114. The stopper 114 is installed at an opening at one end of the fixing member 111, covering the opening at one end of the fixing member 111. The stopper 114 is provided with an avoidance hole 11401.
[0069] Among them, Figure 4 As shown, the sliding member 112 is inserted into the avoidance hole 11401. A blocking portion 1121 is formed on the peripheral wall of the sliding member 112. The blocking portion 1121 is located in the second hole section 11102. At least a portion of the projection of the blocking portion 1121 on the plane where the orifice of the first hole section 11101 is located is located outside the first hole section 11101, and at least a portion of the projection of the blocking portion 1121 on the plane where the orifice of the avoidance hole 11401 is located is located outside the avoidance hole 11401.
[0070] The stopper 114 can limit the movement of the blocking portion 1121, so that the blocking portion 1121 cannot escape from the interior of the fixing portion from the side of the second hole section 11102 away from the first hole section 11101. At least a portion of the projection of the blocking portion 1121 on the plane where the hole opening of the first hole section 11101 is located is located outside the first hole section 11101, so that the blocking portion 1121 cannot enter the first hole section 11101 from the side of the second hole section 11102 close to the first hole section 11101. In this way, when the brake assembly 13 is used for rapid reset, the stopper 114 can prevent the sliding member 112 from escaping from the space inside the fixing member 111 due to a large force.
[0071] That is to say, the blocking portion 1121 can only move in the second hole section 11102. Since the stopper 114 is provided with an avoidance hole 11401 and the sliding member 112 can pass through the first hole section 11101, the movement of the sliding member 112 is restricted by the blocking portion 1121 disposed on its outer wall. The length that the blocking portion 1121 can slide is the length that the sliding member 112 can slide.
[0072] In other embodiments, the range of motion of the sliding member 112 may be limited by other means. The interior of the fixing member 111 may include only one hole segment. A track may be provided on the inner wall of the fixing member 111, and a clamping portion connected to the track may be provided on the outer wall of the sliding member 112 at a position corresponding to the track. The clamping portion and the track can be slidably connected. Blocking portions are provided at both ends of the track.
[0073] The blocking portion allows the clamping portion to slide only within the length range of the track and cannot escape from the length range of the track. Because the clamping portion is connected to the sliding member 112 , the movement length range of the clamping portion is the movement length range of the sliding member 112 .
[0074] In some embodiments, Figure 4 As shown, the inner wall of the fixing member 111 may have a first limiting groove 11103. The peripheral wall of the sliding member 112 is provided with a second limiting groove 11201. The locking member 113 is used to be arranged in the first limiting groove 11103 and the second limiting groove 11201 to lock the fixing member 111 and the sliding member 112.
[0075] When the locking member 113 is located in the first limiting groove 11103 and the second limiting groove 11201 at the same time, the sliding member 112 cannot slide relative to the fixing member 111, so that the reset mechanism 10 can be stably in this state. When the reset mechanism 10 is in this state, the seat 100 can be in zero gravity mode or normal sitting mode. When the screw rod 122 is fully threadedly connected to the sliding member 112, the seat 100 ( Figure 1) is in zero gravity mode, so when the locking member 113 is located in the first limiting groove 11103 and the second limiting groove 11201 at the same time, the mode of the seat 100 can be stably fixed in the zero gravity mode or the normal sitting mode.
[0076] In some embodiments, Figure 4 As shown, a mounting groove 11202 may be provided at one end of the sliding member 112 close to the brake assembly 13. The second limiting groove 11201 is in communication with the mounting groove 11202. The reset assembly 11 further includes a receiving member 115, which is slidably connected in the mounting groove 11202. The receiving member 115 has a bearing groove 11501 on a surface of the side close to the first limiting groove 11103. The locking member 113 is used to be arranged in the second limiting groove 11201 and the bearing groove 11501 to unlock the fixing member 111 and the sliding member 112.
[0077] In the first direction, the length of the receiving member 115 is less than the length of the installation slot 11202. When the end of the receiving member 115 away from the brake assembly 13 contacts the bottom of the installation slot 11202, the bearing slot 11501 is connected and aligned with the second limiting slot 11201. The first direction is the direction in which the sliding member 112 moves.
[0078] like Figure 4 As shown, when the end of the receiving member 115 away from the brake assembly 13 does not contact the bottom of the mounting groove 11202, the bearing groove 11501 cannot be aligned with the second limiting groove 11201, so that the locking member 113 is still located in the first limiting groove 11103 and the second limiting groove 11201, preventing the sliding member 112 from sliding relative to the fixing member 111.
[0079] like Figure 6 As shown, when the end of the receiving member 115 away from the brake assembly 13 contacts the bottom of the installation groove 11202, the bearing groove 11501 is exactly connected and aligned with the second limiting groove 11201, and the locking member will be separated from the first limiting groove 11103 and enter the second limiting groove 11201 and the bearing groove 11501. At this time, the sliding member 112 is unlocked from the fixing member 111, and the sliding member 112 can slide relative to the fixing member 111.
[0080] In some embodiments, Figure 4 As shown, the inner wall of the fixing member 111 may further have a third limiting groove 11104. Along the sliding direction of the sliding member 112, the third limiting groove 11104 and the first limiting groove 11103 are arranged relatively spaced apart.
[0081] Among them, the first limiting groove 11103 and the third limiting groove 11104 can both be located in the first hole section 11101.
[0082] like Figure 4As shown, the reset assembly 11 may further include an elastic member 116. The elastic member 116 is located in the mounting groove 11202, and is located on a side of the receiving member 115 close to the groove bottom of the mounting groove 11202. One end of the elastic member 116 is connected to the groove bottom of the mounting groove 11202, and the other end is connected to the receiving member 115.
[0083] The slot of the installation slot 11202 may have a blocking wall 11203 , and the blocking wall 11203 is provided with an air flow hole 11204 . The blocking wall 11203 can prevent the receiving member 115 from being separated from the installation slot 11202 .
[0084] like Figure 4 As shown, in the initial state, the elastic member 116 generates a force toward the side close to the brake assembly 13, so that the receiving member 115 is closely attached to the blocking wall 11203. At this time, the bearing groove 11501 cannot be aligned with the second limiting groove 11201, and the locking member 113 is located in the first limiting groove 11103 and the second limiting groove 11201. The reset mechanism 10 puts the seat 100 in zero gravity mode.
[0085] When the detonation device in the brake assembly 13 is detonated, a strong airflow will be generated to move toward one side of the sliding member 112. The airflow will act on the blocking wall 11203 of the sliding member 112, and on the receiving member 115 through the airflow hole 11204, because the sliding member 112 cannot slide relative to the fixing member 111 under the action of the locking member 113. However, the receiving member 115 can slide relative to the sliding member 112 in the installation groove 11202 under the action of the airflow, so that the receiving member 115 moves toward the side away from the brake assembly 13, and at the same time, the receiving member 115 will compress the elastic member 116 during this process.
[0086] When the vehicle is hit with a certain force, an electrical signal will be generated. After the electrical signal is received by the brake assembly 13, the detonation device inside it will be detonated.
[0087] like Figure 6 As shown, until the end of the receiving member 115 away from the brake assembly 13 contacts the bottom of the installation groove 11202, the bearing groove 11501 is aligned with the second limiting groove 11201, so that the locking member 113 enters the second limiting groove 11201 and the bearing groove 11501. At this time, the sliding member 112 is unlocked from the fixing member 111, and the sliding member 112 can move toward the side away from the brake assembly 13 under the action of the force applied by the airflow.
[0088] During the sliding process of the sliding member 112 relative to the fixed member 111, the receiving member 115 is always under the action of the elastic member 116, and has a force to move toward the direction close to the brake assembly 13. This force will squeeze the locking member 113, so that the locking member 113 has a force to move toward the side away from the sliding member 112. When the sliding member 112 slides relative to the fixed member 111 until the second limiting groove 11201 is aligned with the third limiting groove 11104, the elastic member 116 will exert a force on the receiving member 115 in the direction close to the brake assembly 13. This force will cause the receiving member 115 to drive the bearing groove 11501 and the second limiting groove 11201 to stagger, thereby squeezing the locking member 113, so that the locking member 113 is subjected to the squeezing force. Under the action of the squeezing force, the locking member 113 is separated from the bearing groove 11501 and enters the second limiting groove 11201 and the third limiting groove 11104.
[0089] like Figure 7 As shown, at this time, the sliding member 112 and the fixing member 111 are locked under the action of the locking member 113 and cannot slide relative to each other. At the same time, the receiving member 115 is no longer limited by the locking member 113 and can slide relative to the sliding member 112 in the installation groove 11202. When the reset mechanism 10 is in this state, the seat 100 ( Figure 1 ) is in a normal sitting position. In this way, the chair 100 can be quickly switched from the zero gravity mode to the normal sitting position mode.
[0090] For example, Figure 4 As shown, the first limiting groove 11103, the bearing groove 11501 and the third limiting groove 11104 can be trapezoidal grooves, wherein the side with a larger opening size of the trapezoidal groove is close to the sliding member 112. The second limiting groove 11201 is a rectangular groove.
[0091] When the first limiting groove 11103, the supporting groove 11501 and the third limiting groove 11104 squeeze the locking member 113, the hypotenuse of the trapezoidal groove can apply a force perpendicular to the hypotenuse to the locking member 113, so that after the locking member 113 is unobstructed on the side away from the trapezoidal groove, it will move to the side away from the trapezoidal groove under the action of the force perpendicular to the hypotenuse, thereby detaching from the trapezoidal groove.
[0092] The second rectangular limiting groove 11201 mainly serves to accommodate the locking member 113 and allow the locking member 113 to move therein. Therefore, the second rectangular limiting groove 11201 can better accommodate the locking member 113, allowing the locking member 113 to pass therein and be located in the first limiting groove 11103, the bearing groove 11501 and the third limiting groove 11104.
[0093] In other embodiments, the first limiting groove 11103, the bearing groove 11501 and the third limiting groove 11104 may also be grooves of other shapes, as long as they can provide a force for the locking member 113 to escape from the groove when it is squeezed.
[0094] For example, Figure 4 As shown, the locking member 113 may be spherical. The locking member 113 of the spherical structure can be easily separated from the trapezoidal groove when being squeezed by the trapezoidal groove. This enhances the smoothness of the operation of the reset mechanism 10 and ensures that the seat 100 ( Figure 1 )The smoothness of switching states.
[0095] In other embodiments, the locking member 113 may also be in other shapes, as long as it can be squeezed on one side and can smoothly enter the space when there is enough space on the other side.
[0096] For example, Figure 4 As shown, the number of the first limiting groove 11103, the second limiting groove 11201, the third limiting groove 11104, the bearing groove 11501 and the locking member 113 can be two, and the two groups can be symmetrically arranged, so that the locking of the locking member 113 can be more stable.
[0097] In other embodiments, the first limiting groove 11103, the second limiting groove 11201, the third limiting groove 11104, the bearing groove 11501 and the locking member 113 may not be symmetrically arranged, as long as the locking member 113 can stably lock the sliding member 112 and the fixing member 111 or the sliding member 112 and the receiving member 115.
[0098] In other embodiments, there is no specific limitation on the number of the first limiting groove 11103, the second limiting groove 11201, the third limiting groove 11104, the bearing groove 11501 and the locking member 113, as long as the locking member 113 can stably lock the sliding member 112 and the fixing member 111 or the sliding member 112 and the receiving member 115.
[0099] In some embodiments, the elastic member 116 may be a spring.
[0100] The spring has good buffering capacity, which can buffer part of the energy and prevent the equipment from being damaged by excessive impact. At the same time, the spring has high wear resistance, which makes it have a long life and can work stably for a long time.
[0101] For example, Figure 4As shown, the type of spring can be a coil spring. The coil spring is tightly wound along the axis, has a small volume, occupies little space, is more suitable for arrangement in a limited space, and can provide the necessary elastic function without affecting the compactness of the overall structure. It is more suitable to be arranged in the installation groove 11202 to apply force to the receiving member 115.
[0102] In other embodiments, the elastic member 116 may also be of the type as long as it can generate elastic force on the receiving member 115 so that the receiving member 115 can work normally.
[0103] In some embodiments, Figure 4 As shown, the surface of the receiving member 115 close to the bottom of the installation groove 11202 may have a first limiting protrusion 1151. The bottom of the installation groove 11202 may have a second limiting protrusion 11205. The two ends of the spring are respectively sleeved on the first limiting protrusion 1151 and the second limiting protrusion 11205.
[0104] The first limiting protrusion 1151 and the second limiting protrusion 11205 can limit the position of the spring between the receiving member 115 and the mounting groove 11202. This ensures that the setting direction of the spring can be along the first direction, thereby ensuring that the direction of the force applied by the spring can also be along the first direction, ensuring that the receiving member 115 can operate according to normal settings.
[0105] In some embodiments, liquid may be contained in the second hole section 11102. Because liquid is fluid and incompressible, it can be used to reduce impact force, vibration, protect equipment or structure from damage, and improve operational stability and safety.
[0106] In some embodiments, Figure 4 As shown, the reset assembly 11 may further include a sealing ring 117, and the number of the sealing rings 117 may be three. One of the sealing rings 117 is located between the stopper 114 and the sliding member 112, another sealing ring 117 is located in the first hole section 11101 on a side close to the second hole section 11102, located between the fixing member 111 and the sliding member 112, and another sealing ring 117 is located in the second hole section 11102.
[0107] Two sealing rings 117 are respectively located on both sides of the second hole section 11102 to seal the space inside the second hole section 11102, thereby preventing the liquid contained therein from leaking. Another sealing ring 117 is located inside the second hole section 11102 to further prevent the liquid in the second hole section 11102 from leaking.
[0108] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
