UTILITY MODEL CONTENT

[0004] In view of the deficiency of prior art, the utility model provides a glass lifter that can be self -rescue and recoverable under emergency working condition, solves the problem proposed in background art.

[0005] The utility model solves the technical problem of the scheme as follows:

[0006] A glass lifter that can be self -rescue and recoverable under emergency working condition, including fixed plate, the fixed plate is installed on the door panel, the first vertical rod and second pull rod are movably installed on the fixed plate, the fixed plate is connected with the connecting plate by pulley and second pull rod, the connecting plate is installed with glass plate;

[0009] On the basis of the above technical scheme, the utility model further can make improvement as follows.

[0010] Further, the sliding block is installed with a pulley, and the sliding block is slidably installed in the first sliding groove through the pulley.

[0011] The beneficial effects of the above further scheme are:

[0012] The installation of the pulley can effectively reduce the friction of the sliding block when sliding in the first sliding groove. This not only makes the sliding process of the sliding block more smooth, but also makes the operation of the glass lifting more easy, and reduces the degree of wear between the components. Reducing wear helps to prolong the service life of the sliding block and the first sliding groove, reduces the probability of failure caused by component wear, and thus improves the reliability and stability of the entire glass lifter.

[0013] Further, the first vertical rod and the second pull rod are installed with pulleys at one end away from the fixing plate, and the connecting plate is provided with a second sliding groove, and the first vertical rod and the second pull rod are installed in the second sliding groove of the connecting plate through the pulleys.

[0014] The beneficial effects of the above further scheme are:

[0015] The first vertical rod and the second pull rod are connected with the second sliding groove of the connecting plate through the pulleys, so that the connection between them is flexible and stable. During the glass lifting process, this connection mode can ensure that the first vertical rod and the second pull rod can move smoothly with the movement of the connecting plate, and can also effectively transmit the force transmitted by the sliding block to the connecting plate to realize the stable lifting of the glass plate. In addition, the rolling of the pulley in the second sliding groove can reduce energy loss and improve transmission efficiency compared with direct sliding friction.

[0016] Further, the driving assembly is composed of a motor and a driving gear, and the diameter of the driving gear is smaller than the diameter of the deflection gear. The motor of the driving assembly drives the driving gear to engage the deflection gear, and then the deflection gear drives the electric push rod to deflect around the fixed rod, so that the electric push rod is separated from the sliding block.

[0017] The beneficial effects of the above further scheme are:

[0018] Since the diameter of the driving gear is smaller than that of the deflection gear, according to the gear transmission principle, when the pinion drives the gear to rotate, the effect of speed reduction and torque increase can be achieved. This means that the motor only needs to output a small power to make the deflection gear obtain enough torque to drive the electric push rod to deflect. In emergency conditions, this design can ensure that the electric push rod quickly and stably separates from the sliding block, and the glass descends due to its own gravity, providing a quick escape channel for the people inside. Moreover, this gear transmission method has high transmission accuracy and reliability, and can ensure that the deflection action of the electric push rod can be accurately realized after multiple uses.

[0019] Further, the electric push rod is fixedly connected with the sliding block through an electromagnet, the electric push rod drives the sliding block to slide in the first sliding groove, and then the sliding block drives the first vertical rod and the second pull rod to push and pull the connecting plate.

[0020] The beneficial effects of the further scheme are:

[0021] The connection mode of the electromagnet and the sliding block has strong controllability. In normal working, the electromagnet generates magnetic force after being powered on, can firmly connect the electric push rod and the sliding block together, ensures that the electric push rod can stably drive the sliding block to slide in the first sliding groove, and realizes normal lifting of the glass plate. When emergency separation is needed, the power supply of the electromagnet is only needed to be cut off, so that the connection can be quickly released, the electric push rod is separated from the sliding block. Compared with the traditional mechanical connection, the operation is more simple and fast, the response speed of the glass lifter in the emergency condition can be effectively improved, and the safety and practicability of the whole system are enhanced.

[0022] The utility model provides a kind of glass lifter that can be self-rescued and recovered under emergency working condition. It has the following beneficial effects:

[0023] When emergency working condition occurs, the person in the vehicle needs to quickly open the window to escape, at this time, the motor of the driving assembly drives the driving gear to engage the deflection gear, so that the electric push rod can be quickly deflected with the fixed rod as the center, and separated from the sliding block. Due to the gravity of the glass plate itself, the connecting plate will drive the glass plate to quickly descend, the whole process responds quickly, and valuable escape time is gained for the person in the vehicle. After the emergency condition is removed, the motor of the driving assembly drives the driving gear to engage the deflection gear again, and the electric push rod can be accurately restored to the connected state with the sliding block, so that the glass lifter returns to normal work. This recovery method is simple and convenient, without manual complex connection or debugging operation, time and labor cost are saved.

[0024] The stable lifting of the glass plate is realized through the cooperative work of the fixing plate, the first vertical rod, the second pull rod, the connecting plate, the sliding block and the electric push rod. The electric push rod drives the sliding block to slide in the first sliding groove, and then drives the first vertical rod and the second pull rod to push and pull the connecting plate. This transmission mode is simple and direct, and can effectively convert the linear motion of the electric push rod into the up-down motion of the connecting plate, drive the glass plate to lift, and has high transmission efficiency, which can ensure the smoothness of the glass lifting. The installation positions and connection modes of the components are carefully designed. For example, the first vertical rod and the second pull rod are installed in the second sliding groove of the connecting plate through pulleys, which not only ensures the stability of the connection, but also makes the relative movement between the components more flexible; the sliding block is slidingly installed in the first sliding groove through a pulley, which reduces the sliding friction and improves the smoothness of the movement; the electric push rod is movably installed on the fixing plate through a deflection gear, so that the electric push rod can be flexibly deflected when needed, and the sliding block is separated and connected, the whole layout is compact and reasonable, and the space is fully utilized, and the cooperative work effect between the components is also ensured.

[0025] The connection mode of the strong magnet and the electromagnet ensures the stable connection between the electric push rod and the sliding block during normal work. The magnetic force generated by the strong magnet and the electromagnet can provide sufficient attraction force, so that the sliding block can stably slide in the first sliding groove under the drive of the electric push rod, and the stability and accuracy during the glass lifting process are ensured, and the shaking or jamming phenomenon is not easy to occur. The design of the deflection gear and the driving assembly ensures the reliable deflection operation of the electric push rod. The fixed rod is installed in the deflection gear through a bearing, so that the electric push rod can be flexibly deflected with the fixed rod as the center; the driving assembly is composed of a motor and a driving gear, and the diameter of the driving gear is smaller than that of the deflection gear. This design can provide a suitable transmission ratio, so that the power of the motor can be effectively transmitted to the deflection gear to drive the electric push rod to accurately perform the deflection action, and the slipping or transmission failure is not easy to occur, thereby ensuring the reliability of the glass lifter during the emergency self-rescue and recovery process.

[0035] Please refer to Figures 1 to 4 The utility model provides an embodiment:

[0036] Embodiment one: an emergency self-rescue and recoverable glass lifter, comprising a fixed plate 1 installed on the door panel, a first vertical rod 8 and a second pull rod 9 movably installed on the fixed plate 1, a connecting plate 10 connected with the fixed plate 1 through the pulley 2 and the second pull rod 9, the first vertical rod 8 and the second pull rod 9 are installed with the pulley 2 at the end away from the fixed plate 1, a second sliding groove 1001 is opened on the connecting plate 10, the first vertical rod 8 and the second pull rod 9 are installed in the second sliding groove 1001 of the connecting plate 10 through the pulley 2, and the cooperation of the pulley 2 and the second sliding groove 1001 of the connecting plate 10 makes the connection between them flexible and stable. During the glass lifting process, this connection mode can ensure that the first vertical rod 8 and the second pull rod 9 can smoothly move with the movement of the connecting plate 10, and at the same time can effectively transmit the force transmitted by the sliding block 7 to the connecting plate 10, realizing the stable lifting of the glass plate. In addition, the rolling of the pulley 2 in the second sliding groove 1001 can reduce energy loss and improve transmission efficiency compared with direct sliding friction. The connecting plate 10 is installed with a glass plate, a first sliding groove 101 is opened on the fixed plate 1, a sliding block 7 is slidably installed in the first sliding groove 101, the pulley 2 is installed on the sliding block 7, and the sliding block 7 is slidably installed in the first sliding groove 101 through the pulley 2. The installation of the pulley 2 can effectively reduce the friction of the sliding block 7 when sliding in the first sliding groove 101. This not only makes the sliding process of the sliding block 7 more smooth, making the operation of glass lifting more easy, but also reduces the degree of wear between parts. Reducing wear helps to prolong the service life of the sliding block 7 and the first sliding groove 101, reduces the probability of failure caused by wear of parts, thereby improving the reliability and stability of the entire glass lifter, the end of the first vertical rod 8 away from the connecting plate 10 is rotationally connected with the sliding block 7, one side of the sliding block 7 is provided with a strong magnet, the end of the second pull rod 9 away from the connecting plate 10 is rotationally connected with one end of the fixed plate 1, and the connecting end of the fixed plate 1 and the second pull rod 9 is away from the end provided with the first sliding groove 101, the middle of the first vertical rod 8 and the second pull rod 9 is rotationally connected through a pin shaft, the end of the fixed plate 1 close to the second pull rod 9 is installed with an electric push rod 4, the output end of the electric push rod 4 is installed with an electromagnet 3, the electric push rod 4 and the sliding block 7 are connected through the strong magnet and the electromagnet 3, the sliding block 7 is driven to slide in the first sliding groove 101 through the electric push rod 4, and then the first vertical rod 8 and the second pull rod 9 drive the connecting plate 10 through the sliding block 7, the connection mode of the electromagnet 3 and the sliding block 7 has strong controllability. In normal working condition, the electromagnet 3 generates magnetic force after being electrified, which can firmly connect the electric push rod 4 and the sliding block 7 together, ensuring that the electric push rod 4 can stably drive the sliding block 7 to slide in the first sliding groove 101, realizing the normal lifting of the glass plate. When emergency separation is needed, the power supply of the electromagnet 3 is cut off, so that the electric push rod 4 and the sliding block 7 are quickly disconnected.Compared with the traditional mechanical connection, the connection is more convenient and fast, and can effectively improve the response speed of the glass lifter in an emergency and enhance the safety and practicability of the whole system.

[0037] In order to realize the self-rescue and recovery function of the glass lifter in an emergency working condition, improve the safety of the passengers in the vehicle and the reliability of the glass lifter, for example, as shown in the drawings, Figures 1 to 4 The utility model also includes: the electric push rod 4 is movably installed on the fixed plate 1 through the deflection gear 6, the fixed rod 601 is installed in the deflection gear 6 through a bearing, the electric push rod 4 is installed on the fixed plate 1 through the fixed rod 601 of the deflection gear 6, the drive assembly 5 is installed on one side of the deflection gear 6 on the fixed plate 1, and the drive assembly 5 is in transmission connection with the deflection gear 6, the drive assembly 5 is composed of a motor and a drive gear, and the diameter of the drive gear is less than the diameter of the deflection gear 6, when self-rescue is needed in an emergency working condition, the motor of the drive assembly 5 drives the drive gear to mesh with the deflection gear 6, and then the deflection gear 6 drives the electric push rod 4 to deflect with the fixed rod 601 as the center, so that the electric push rod 4 is separated from the sliding block 7, at this time, the glass plate is lowered due to its own gravity, and the sliding block 7 slides on the fixed plate 1 to the direction of the electric push rod 4, when recovery is needed, the motor of the drive assembly 5 drives the drive gear to mesh with the deflection gear 6, so that the deflection gear 6 drives the electric push rod 4 to deflect with the fixed rod 601 as the center, so that the output end of the electric push rod 4 restores the connection state with the sliding block 7 through the strong magnet and the electromagnet 3, since the diameter of the drive gear is less than that of the deflection gear 6, according to the gear transmission principle, when the small gear drives the large gear to rotate, the effect of speed reduction and torque increase can be realized. This means that the motor only needs to output a small power to make the deflection gear 6 obtain enough torque to drive the electric push rod 4 to deflect. In an emergency working condition, this design can ensure that the electric push rod 4 is quickly and stably separated from the sliding block 7, and the glass is lowered due to its own gravity, providing a quick escape channel for the passengers in the vehicle. Moreover, this gear transmission mode has high transmission accuracy and reliability, and can ensure that the deflection action of the electric push rod 4 can be accurately realized after multiple uses.

[0038] Working principle:

[0039] The glass lifter works normally by the power of the electric push rod 4. After the electric push rod 4 is started, the electromagnet 3 at the output end of the electric push rod 4 generates magnetic force, and is attracted to the strong magnet on the sliding block 7, forming a stable connection. Based on this, the linear motion of the electric push rod 4 is converted into the sliding of the sliding block 7 in the first sliding groove 101 of the fixed plate 1. Since the first vertical rod 8 is rotationally connected with the sliding block 7, the movement of the sliding block 7 drives the first vertical rod 8 to act. The first vertical rod 8 and the second pull rod 9 are rotationally connected through a pin shaft at the middle position, and the second pull rod 9 is rotationally connected with the fixed plate 1 at one end. This special structure makes the movement of the first vertical rod 8 transmitted to the second pull rod 9 through the pin shaft, and the two work together to push and pull the connecting plate 10 connected with the glass plate. The first vertical rod 8 and the second pull rod 9 are connected with the second sliding groove 1001 of the connecting plate 10 through the pulley 2, which ensures that the connecting plate 10 can move up and down smoothly during the pushing and pulling process, thereby realizing the smooth lifting of the glass plate.

[0040] When facing an emergency working condition, the emergency self-rescue mechanism is started. The motor of the drive assembly 5 starts to operate, and the motor drives the drive gear to rotate. The drive gear is meshed with the deflection gear 6, and the diameter of the drive gear is smaller than that of the deflection gear 6. According to the gear transmission characteristics, the small gear driving the large gear can generate a large torque to drive the deflection gear 6 to rotate. The electric push rod 4 is installed on the fixed plate 1 through the fixed rod 601, and the fixed rod 601 is located inside the deflection gear 6. Therefore, when the deflection gear 6 rotates, it drives the electric push rod 4 to deflect around the fixed rod 601. With the deflection of the electric push rod 4, its output end is separated from the sliding block 7. At the same time, the output end of the electric push rod 4 is reset to the initial position. At this time, the glass plate is pulled down by the connecting plate 10 due to its own gravity. In this process, the connecting plate 10 is connected with the first vertical rod 8 and the second pull rod 9 through the second sliding groove 1001 and the pulley 2, driving the first vertical rod 8 and the second pull rod 9 to act synchronously, and the sliding block 7 slides on the fixed plate 1 towards the direction of the electric push rod 4. In this way, the glass can quickly descend to provide an emergency escape channel for the people inside the vehicle, and the whole process responds quickly to save valuable escape time for the people inside the vehicle.

[0041] After the emergency is over, the glass lifter needs to return to normal work. The motor of the drive assembly 5 is started again, the motor drives the drive gear to rotate, the drive gear is meshed with the deflection gear 6 to drive the deflection gear 6 to rotate. The deflection gear 6 drives the electric push rod 4 to reverse and reset around the fixed rod 601, and then the electric push rod 4 is started. The electromagnet 3 at the output end of the electric push rod 4 is re-attracted to the strong magnet on the sliding block 7. After the connection is restored, the electric push rod 4 restores the drive of the sliding block 7, drives the sliding block 7 to slide in the first sliding groove 101, and then drives the connecting plate 10 to rise through the first vertical rod 8 and the second pull rod 9, so that the glass plate rises, and the glass lifter returns to the normal working state. This recovery method is simple and does not require complex manual operation, saving time and labor cost.
