Intake valve.
通常情况下,人们考虑车辆的侧翻,一般视野在于重心的被动调整。本申请由于采用了充气泵,因而也利用了这种机制。一般而言,减震结构在车辆发生侧翻的过程中,起着助纣为虐的作用。由于减震结构避免车身和车桥的刚性连接,因为较为柔韧。但在转弯过程中,由于离心力的作用,位于转弯半径外侧的减震结构会背压缩进一步加剧车辆重心向外侧偏转。Usually, people consider the rollover of the vehicle, and the general vision lies in the passive adjustment of the center of gravity. This application also utilizes this mechanism due to the use of an air pump. Generally speaking, the shock-absorbing structure plays a role in helping the tyrant when the vehicle rolls over. Because the shock absorbing structure avoids the rigid connection of the body and the axle, it is more flexible. However, during the turning process, due to the centrifugal force, the shock absorbing structure located on the outside of the turning radius will back compress and further aggravate the outward deflection of the vehicle's center of gravity.
采用本方案之后,在车辆行驶中,离心力感应开关一直常开状态,但由于转向感应开关控制离心力感应开关的通电,因而如果不转弯,离心力感应开关并不工作。After adopting this scheme, when the vehicle is running, the centrifugal force sensing switch is always on, but since the steering sensing switch controls the energization of the centrifugal force sensing switch, the centrifugal force sensing switch does not work if there is no turning.
本方案由于设置了减震气囊,所以设置了拉簧,以消解车辆震动形成的振动,防止减震气囊的弹起导致车身重心升高。Because the shock-absorbing airbag is provided in this program, an extension spring is provided to eliminate the vibration caused by the vehicle vibration and prevent the bouncing of the shock-absorbing airbag from causing the center of gravity of the vehicle body to rise.
在车辆转弯行驶中,如果方向盘转动足够大,转向助力油管的压力会启动转向感应开关。When the vehicle is turning, if the steering wheel is turned sufficiently, the pressure in the power steering hose will activate the steering sensor switch.
此时,转向感应开关电连接的充气泵启动,开始准备工作;转向感应开关电连接的第一限压阀均关闭气道,以防止车身的离心力压迫使外侧减震气囊憋下去。At this time, the air pump electrically connected to the steering sensor switch starts to start preparations; the first pressure limiting valve electrically connected to the steering sensor switch all closes the air passage to prevent the centrifugal force of the vehicle body from forcing the outer shock-absorbing airbag to hold back.
为了便于说明,我们假设车辆此刻左转,离心力向右侧。若是离心力较大,导致离心力感应开关应打开了左侧旋钮。此时,左侧旋钮打开了左侧减震气囊的排气阀,关闭了左侧减震气囊的第一进气阀,打开了右侧第二进气阀的气道。于是,左侧减震气囊开始排气,右侧减震气囊的限压数值提高,并可能开始充气。充气可能状态为,离心力对气囊的压迫导致右侧减震气囊的气压还处于限压数值之下时。右侧拉簧不工作。For the sake of illustration, we assume that the vehicle is turning left at this moment, and the centrifugal force is to the right. If the centrifugal force is large, the left knob should be opened by the centrifugal force sensor switch. At this time, the left knob opens the exhaust valve of the left shock absorber airbag, closes the first intake valve of the left shock absorber airbag, and opens the air passage of the second right intake valve. As a result, the left airbag begins to deflate, and the pressure limit value of the right airbag increases and may begin to inflate. The possible state of inflation is when the air pressure of the right shock-absorbing airbag is still below the pressure limit value due to the compression of the airbag by the centrifugal force. Right side tension spring does not work.
这样的话,如果离心力不是太大,则不需要减震气囊排气,以减轻充气机负担。In this way, if the centrifugal force is not too large, there is no need to exhaust the shock-absorbing airbag to reduce the burden on the inflator.
当转弯完成之后,左侧排气阀关闭,左侧第一进气阀打开,左侧的减震气囊由蓄气罐开始充气。右侧第二进气阀关闭,右侧拉簧开始工作。第一限压阀开始工作。在车辆行驶的晃动中,两侧拉簧和第一减压阀最终会使两侧平衡。After the turn is completed, the left exhaust valve is closed, the first left intake valve is opened, and the left shock absorber air bag is inflated by the gas storage tank. The second intake valve on the right is closed, and the right extension spring starts to work. The first pressure limiting valve starts to work. During the shaking of the vehicle running, the tension springs on both sides and the first pressure reducing valve will finally balance the two sides.
以上内容皆为被动的重心调整以避免侧翻。由于本申请侧重于被动调整不能奏效,主动调整车身整体受力变化,以矫正车身倾斜角度。The above content is passive center of gravity adjustment to avoid rollover. Because this application focuses on passive adjustment, it cannot be effective, and actively adjusts the overall force change of the vehicle body to correct the inclination angle of the vehicle body.
正由于电动车车身较轻,而爆发式喷气能够提供足够的矫正力,因而本申请提供了一种爆发式喷气对抗离心力的系统。在被动的重心调整运作不能奏效的情况下,蓄气罐的高压空气经由直径大于一般通气管的连通管,最后由喷气阀快速释放,从而产生一个能抵抗离心力矫正车辆姿态的反推力。Just because the body of the electric vehicle is relatively light, and the explosive jet can provide sufficient correcting force, the application provides a system for resisting centrifugal force by the explosive jet. When the passive center of gravity adjustment operation fails, the high-pressure air from the gas storage tank passes through a connecting pipe with a diameter larger than that of the general air pipe, and finally is quickly released by the jet valve, thereby generating a reverse thrust that can resist centrifugal force and correct the vehicle's attitude.
喷气阀竖直向上设置,是考虑喷射的气流不会影响到周围偶尔的同行者。为了防止喷射的气流导致车身损坏,而且极快的喷气会带来噪音,故设置扩散气道竖直向上,既保护了气流破坏车身,又能将噪音引导向上。The jet valve is set vertically upwards to consider that the jet air flow will not affect the occasional companions around. In order to prevent the jet air from damaging the body, and the extremely fast jet will cause noise, the diffuser air duct is set up vertically, which not only protects the air from damaging the body, but also guides the noise upward.
极快的喷气,会产生震动,所以设置了防震衬件;喷气阀设置环形盘是为了防止反推力使喷气阀飞出。Extremely fast air jets will generate vibrations, so anti-vibration linings are installed; the jet valve is provided with an annular disc to prevent the jet valve from flying out due to reverse thrust.
设置抗喷气冲击架是为了不让喷气冲击力破坏车身结构,而抗喷气冲击架设置在减震气囊上是为了把冲击力直接向下传递到车轮,防止让车身的纵向结构承载过大的瞬间弯矩负荷。The purpose of setting up the anti-jet impact frame is to prevent the jet impact force from damaging the body structure, and the anti-jet impact frame is set on the shock absorbing airbag to transmit the impact force directly downward to the wheels, preventing the moment when the longitudinal structure of the vehicle body is overloaded. Bending moment load.
本方案的有益效果可根据对上述方案的叙述得知,结构简单、设计合理,能使电动车在转弯时避免发生侧翻,在转弯中,不但能降低转弯半径内侧的高度,以及使车身整体相对车桥向转弯半径内侧移动,而且能在车身倾斜角度过大时,产生一个爆发的喷气反推力抵抗离心力并矫正车身姿态。The beneficial effect of this scheme can be known according to the description of the above scheme. The structure is simple and the design is reasonable, which can prevent the electric vehicle from rolling over when turning. The relative axle moves to the inner side of the turning radius, and can generate an explosive jet reverse thrust to resist centrifugal force and correct the posture of the vehicle body when the vehicle body tilt angle is too large.

通常情况下,人们考虑车辆的侧翻,一般视野在于重心的被动调整。本申请由于采用了充气泵,因而也利用了这种机制。一般而言,减震结构在车辆发生侧翻的过程中,起着助纣为虐的作用。由于减震结构避免车身1和车桥2的刚性连接,因为较为柔韧。但在转弯过程中,由于离心力的作用,位于转弯半径外侧的减震结构会背压缩进一步加剧车辆重心向外侧偏转。Usually, people consider the rollover of the vehicle, and the general vision lies in the passive adjustment of the center of gravity. This application also utilizes this mechanism due to the use of an air pump. Generally speaking, the shock-absorbing structure plays a role in helping the tyrant when the vehicle rolls over. Due to the shock-absorbing structure, the rigid connection of the vehicle body 1 and the
采用本方案之后,在车辆行驶中,离心力感应开关一直常开状态,但由于转向感应开关控制离心力感应开关的通电,因而如果不转弯,离心力感应开关并不工作。After adopting this scheme, when the vehicle is running, the centrifugal force sensing switch is always on, but since the steering sensing switch controls the energization of the centrifugal force sensing switch, the centrifugal force sensing switch does not work if there is no turning.
本方案由于设置了减震气囊3,所以设置了拉簧30,以消解车辆震动形成的振动,防止减震气囊3的弹起导致车身1重心升高。Since the shock-absorbing
在车辆转弯行驶中,如果方向盘转动足够大,转向助力油管19的压力会启动转向感应开关。When the vehicle is turning, if the steering wheel is rotated sufficiently, the pressure of the power
此时,转向感应开关电连接的充气泵启动,开始准备工作;转向感应开关电连接的第一限压阀9均关闭气道,以防止车身1的离心力压迫使外侧减震气囊3憋下去。At this time, the air pump electrically connected to the steering sensor switch starts and starts to prepare; the first
为了便于说明,我们假设车辆此刻左转,离心力向右侧。若是离心力较大,导致离心力感应开关应打开了左侧旋钮。此时,左侧旋钮打开了左侧减震气囊3的排气阀6,关闭了左侧减震气囊3的第一进气阀7,打开了右侧第二进气阀37的气道。于是,左侧减震气囊3开始排气,右侧减震气囊3的限压数值提高,并可能开始充气。充气可能状态为,离心力对气囊的压迫导致右侧减震气囊3的气压还处于限压数值之下时。右侧拉簧30不工作。For the sake of illustration, we assume that the vehicle is turning left at this moment, and the centrifugal force is to the right. If the centrifugal force is large, the left knob should be opened by the centrifugal force sensor switch. Now, the left side knob opens the
这样的话,如果离心力不是太大,则不需要减震气囊3排气,以减轻充气机负担。In this way, if the centrifugal force is not too large, the shock-absorbing
当转弯完成之后,左侧排气阀6关闭,左侧第一进气阀7打开,左侧的减震气囊3由蓄气罐8开始充气。右侧第二进气阀37关闭,右侧拉簧30开始工作。第一限压阀9开始工作。在车辆行驶的晃动中,两侧拉簧30和第一减压阀9最终会使两侧平衡。After the turning was completed, the
以上内容皆为被动的重心调整以避免侧翻。由于本申请侧重于被动调整不能奏效,主动调整车身1整体受力变化,以矫正车身1倾斜角度。The above content is passive center of gravity adjustment to avoid rollover. Since this application focuses on passive adjustment, it cannot be effective, and actively adjusts the overall force change of the vehicle body 1 to correct the inclination angle of the vehicle body 1 .
正由于电动车车身1较轻,而爆发式喷气能够提供足够的矫正力,因而本申请提供了一种爆发式喷气对抗离心力的系统。在被动的重心调整运作不能奏效的情况下,蓄气罐8的高压空气经由直径大于一般通气管的连通管28,最后由喷气阀23快速释放,从而产生一个能抵抗离心力矫正车辆姿态的反推力。Just because the body 1 of the electric vehicle is relatively light, and the explosive jet can provide sufficient corrective force, the present application provides a system for resisting centrifugal force by the explosive jet. When the passive center of gravity adjustment operation fails, the high-pressure air from the
喷气阀23竖直向上设置,是考虑喷射的气流不会影响到周围偶尔的同行者。为了防止喷射的气流导致车身1损坏,而且极快的喷气会带来噪音,故设置扩散气道24竖直向上,既保护了气流破坏车身1,又能将噪音引导向上。
极快的喷气,会产生震动,所以设置了防震衬件26;喷气阀23设置环形盘27是为了防止反推力使喷气阀23飞出。Extremely fast jet will produce vibrations, so a
设置抗喷气冲击架25是为了不让喷气冲击力破坏车身1结构,而抗喷气冲击架25设置在减震气囊3上是为了把冲击力直接向下传递到车轮,防止让车身1的纵向结构承载过大的瞬间弯矩负荷。The
