In addition, the present invention also relates to a maglev train comprising the energy absorbing and anti-collision device for maglev trains. Background Art

[0002] The maglev train (magnetic levitation, referred to as Maglev), relies on magnetic force to achieve train operation, with low running resistance and high running speed.

[0003] However, in the related art, due to the high running speed of the maglev train, if there is an obstacle in front of the train, it is difficult for the driver to react in a very short time, which can easily cause the train to collide with the obstacle in front of it, causing serious consequences.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The core of the present invention is to provide an energy-absorbing and anti-collision device for a maglev train, which can give the driver a longer reaction time to brake the train when there is an obstacle in front of the maglev train. Another core of the present invention is to provide a maglev train comprising the energy-absorbing and anti-collision device for a maglev train, which can give the driver a longer reaction time to brake the train when there is an obstacle in front of the maglev train.

[0046] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides an energy absorption and anti-collision device for a maglev train, which is mainly installed on a maglev train 10. The energy absorption and anti-collision device for a maglev train includes an installation box 1, a box body 2, a detection component 3, an electromagnetic device and a commutation device. The installation box 1 is used to be installed on the front of the maglev train 10; the box body 2 is connected to the installation box 1; the detection component 3 is arranged in the box body 2, and is used to detect whether there is an obstacle in front of the maglev train 10; the electromagnetic device includes an electromagnet 4 arranged in the box body 2 and a power supply connected to the electromagnet 4, and the power supply is used to provide a unidirectional current to the electromagnet 4; the commutation device is arranged in the box body 2, and the commutation device is connected between the electromagnet 4 and the power supply, and is used to periodically change the current direction of the electromagnet 4, so that the magnetic pole of the electromagnet 4 is the same as the magnetic pole of the rail electromagnet 101 corresponding to the front of the maglev train 10 on the train track where the maglev train 10 runs.

[0047] When in use, the energy absorption and anti-collision device for a maglev train is installed on the front of the maglev train 10 through the installation box 1. When the detection member 3 detects that there is an obstacle in front of the maglev train 10, a unidirectional current is provided to the electromagnet 4 through the power supply, and the current direction of the electromagnet 4 is periodically changed through the reversing device, so that the magnetic pole of the electromagnet 4 is the same as the magnetic pole of the rail electromagnet 101 corresponding to the frontmost rail electromagnet 10 of the maglev train 10 on the train track where the maglev train 10 runs. At the same time, the magnetic pole of the electromagnet 4 is opposite to the magnetic pole of the rail electromagnet 101 adjacent to the frontmost rail electromagnet 10 of the maglev train 10. Therefore, the maglev train 10 can be decelerated by utilizing the principle that magnets with the same poles repel each other and magnets with different poles attract each other. In this way, by decelerating the maglev train 10, a longer reaction time can be reserved for the driver, so that the driver has enough time to decelerate and brake the maglev train 10, thereby reducing safety hazards.

[0048] It should be noted that the present embodiment does not limit the specific structure, arrangement and detection principle of the detection member 3, as long as it can detect whether there is an obstacle in front of the maglev train 10. In some embodiments, the detection member 3 includes at least one distance sensor, and the distance sensor is arranged on the anti-collision beam 82. When the number of the distance sensors is at least three, the distance sensors are arranged on the anti-collision beam 82 at equal intervals, such as Figure 2 In some embodiments, the distance sensor is an acoustic wave distance sensor.

[0049] It should be noted that this embodiment does not limit the specific structure and working principle of the commutation device, as long as the commutation device can periodically change the direction of the current flowing to the electromagnet 4, thereby causing the magnetic pole of the electromagnet 4 to change periodically.

[0050] Please refer to Figures 3 to 7 In some embodiments, the commutation device includes a turntable 5 and a rotation drive mechanism 6, the turntable 5 includes a first contact 51, a second contact 52 and a third contact 53, the first contact 51 is used to be electrically connected to the electromagnet 4, the second contact 52 and the third contact 53 are both used to be electrically connected to a power supply, and the second contact 52 and the third contact 53 are electrically connected to the first contact 51 respectively, and the current direction between the second contact 52 and the first contact 51 is opposite to the current direction between the third contact 53 and the first contact 51; the rotation drive mechanism 6 is connected to the turntable 5, and is used to drive the turntable 5 to rotate, so that the first contact 51 is periodically connected to the electromagnet 4 during the rotation of the turntable 5, and the second contact 52 and the third contact 53 are alternately and periodically connected to the power supply, and when the first contact 51 is in contact with the electromagnet 4, one of the second contact 52 and the third contact 53 is connected to the power supply.

[0051] That is to say, in this embodiment, the rotary drive mechanism 6 rotates to drive the turntable 5 to rotate. When the turntable 5 rotates, the first contact 51, the second contact 52 and the third contact 53 are driven to rotate, so that the first contact 51 is periodically connected to the electromagnet 4 to achieve periodic conductivity between the first contact 51 and the electromagnet 4, and the second contact 52 and the third contact 53 are alternately and periodically connected to the power supply to periodically reverse the unidirectional current provided by the power supply and conduct it to the first contact 51, thereby achieving a periodic change in the current direction of the electromagnet 4.

[0052] It should be noted that the present embodiment does not limit the specific structure of the rotation drive mechanism 6, as long as it can output rotational motion to drive the turntable 5 to rotate. In some embodiments, the rotation drive mechanism 6 is a motor.

[0053] Furthermore, in order to facilitate the alternating and periodic connection of the second contact 52 and the third contact 53 with the power supply, in some embodiments, the installation box 1 is provided with a fourth contact 11, and the fourth contact 11 is electrically connected to the power supply; the box body 2 is provided with a fifth contact 21 that is in contact and conductive with the fourth contact 11 and a sixth contact 22 that is electrically connected to the fifth contact 21, and the second contact 52 and the third contact 53 are respectively connected to the power supply by contacting the sixth contact 22.

[0054] That is to say, during the rotation of the turntable 5, the second contact 52 and the third contact 53 are alternately and periodically in contact with the sixth contact 22, and the sixth contact 22 is electrically connected to the fifth contact 21, the fifth contact 21 is in contact with the fourth contact 11, and the fourth contact 11 is electrically connected to the power supply. Therefore, in this way, the second contact 52 and the third contact 53 can be alternately and periodically connected to the power supply. This method is simple, convenient and easy to implement.

[0055] It should be noted that the embodiment of the present invention does not limit the specific location of the power supply, etc. The power supply can be the power supply of the maglev train 10 itself, which is arranged inside the maglev train 10, or it can be an independent power supply module specifically used to provide unidirectional current to the electromagnet 4, and it can be carried on the maglev train 10, or it can be arranged in the box 2 or the installation box 1, etc. In addition, the embodiment of the present invention does not limit the specific connection method between the contacts that need to be electrically connected, as long as the electrical connection between the contacts that need to be connected can be achieved. Similarly, the embodiment of the present invention does not specifically limit the way the contacts are electrically connected to the power supply or the electromagnet 4, as long as the corresponding electrical connection can be achieved.

[0056] In addition, in order to facilitate the connection between the electromagnet 4 and the first contact 51, as shown in FIG. Figure 3As shown, in some embodiments, the electromagnet 4 includes two first electromagnets 41 and second electromagnets 42 arranged in parallel, the turntable 5 is arranged between the first electromagnet 41 and the second electromagnet 42, the number of the first contacts 51 is two pairs, and the two pairs of first contacts 51 are symmetrically arranged on the side of the turntable 5 about the turntable 5, and the first electromagnet 41 and the second electromagnet 42 are respectively in contact with the side of the turntable 5 through the connecting joint 43, so that the first electromagnet 41 and the second electromagnet 42 are simultaneously connected to the corresponding first contacts 51.

[0057] It can be understood that the first electromagnet 41 and the second electromagnet 42 correspond to the magnets on both sides of the train track respectively. Through the two pairs of first contacts 51 symmetrically arranged on the turntable 5, the two pairs of first contacts 51 can respectively and simultaneously contact the first electromagnet 41 and the second electromagnet 42 respectively, so that the first electromagnet 41 and the second electromagnet 42 work at the same time to enhance the magnetic force between the electromagnet 4 and the rail electromagnet 101.

[0058] In addition, in order to reasonably utilize the kinetic energy of the maglev train 10 when it is decelerated under the action of the electromagnet 4 and save energy, as Figures 8 to 10 As shown, in some embodiments, the box body 2 is provided with a rotatable mounting member 71 and a limiting member 72 for limiting the mounting member 71, and a first elastic member 73 is connected between the mounting member 71 and the box body 2, and the first elastic member 73 is used to provide an elastic force to the mounting member 71 to press the mounting member 71 against the train track after the limiting member 72 releases the limiting member 71; the mounting member 71 is provided with a rotating wheel 74 and a generator 75, and the generator 75 is connected to a storage battery 76 (such as Figure 5 As shown in the figure), the battery 76 is arranged in the box body 2, and the battery 76 is connected to the rotation drive mechanism 6.

[0059] It is understandable that, under normal circumstances, the position limiting member 72 is used to limit the mounting member 71, so that the mounting member 71 lifts the rotating wheel 74, so that the rotating wheel 74 is separated from the train track, and the rotating wheel 74 is prevented from affecting the normal operation of the maglev train 10. When the detection member 3 detects that there is an obstacle in front of the maglev train 10, the position limiting member 72 can release the position limiting member 71, so that the mounting member 71 rotates under the elastic force of the first elastic member 73, so that the rotating wheel 74 contacts the train track and generates a squeezing force on the train track, thereby rotating the rotating wheel 74. When the rotating wheel 74 rotates, the generator 75 generates electricity and stores the electric energy in the storage battery 76. Then, the electric energy of the storage battery 76 is used to power the rotating drive mechanism 6, so that the rotating drive mechanism 6 drives the turntable 5 to rotate. That is to say, in this embodiment, when the detection component 3 detects that there is an obstacle in front of the maglev train 10, the kinetic energy of the maglev train 10 can be converted into electrical energy to drive the rotation drive mechanism 6, so that the rotation drive mechanism 6 drives the turntable 5 to rotate, which is beneficial to saving energy.

[0060] It should be noted that the present embodiment does not limit the specific connection method between the generator 75 and the battery 76, as long as the electrical connection between the two can be achieved. In some embodiments, the connection line of the generator 75 enters the interior of the box 2 through the hinged portion of the mounting member 71 and the box 2, and is connected to the battery 76 in the box 2.

[0061] Furthermore, in order to facilitate the limit member 72 to release the limit on the mounting member 71 in time, in some embodiments, the limit member 72 is a DC electric push rod, and the limit member 72 is connected to the battery 76. The limit member 72 is used to limit the position of the mounting member 71 when the detection member 3 does not detect the existence of an obstacle in front of the maglev train 10, and to operate to release the limit on the mounting member 71 when the detection member 3 detects the existence of an obstacle in front of the maglev train 10.

[0062] That is, this embodiment controls the action of the limiter 72 in real time according to the detection signal of the detection member 3, so that when the detection member 3 detects that there is an obstacle in front of the maglev train 10, the limiter 72 can release the mounting member 71 in time. At the same time, the battery 76 is used to directly drive the limiter 72, which facilitates the electrical connection of the limiter 72.

[0063] Furthermore, if Fig.11 As shown, in some embodiments, a protective box 81 is connected to the side of the box body 2 away from the installation box 1, and an anti-collision beam 82 is provided on the side of the protective box 81 away from the box body 2. That is to say, even when the maglev train 10 collides with an obstacle in front of it, the anti-collision beam 82 can be used to absorb the external impact force and reduce the impact on the maglev train 10. In some embodiments, the anti-collision beam 82 is an anti-collision beam 82 made of carbon fiber composite material. In addition, the embodiment of the present invention does not limit the specific structure of the anti-collision beam 82, as long as it can absorb the external impact force.

[0064] Furthermore, if Fig.11 As shown, in some embodiments, at least one hollow support push rod 83 is connected between the anti-collision beam 82 and the protection box 81, a hydraulic cylinder 84 is provided in the protection box 81, and fluid medium is provided inside the hydraulic cylinder 84 and the support push rod 83.

[0065] That is to say, in this embodiment, the support push rod 83 and the hydraulic cylinder 84 are used to form a first impact absorbing mechanism. When the maglev train 10 collides with an obstacle in front of it, the first impact absorbing mechanism is used to absorb the energy generated by the collision. It can be understood that the support push rod 83 is connected to the hydraulic cylinder 84. According to Pascal's law, when a collision occurs at the anti-collision beam 82, the fluid medium inside the hydraulic cylinder 84 transmits pressure, which can achieve a shock-absorbing effect. This embodiment does not specifically limit the fluid medium. For example, the fluid medium can be hydraulic oil.

[0066] In addition, the present embodiment does not limit the specific number of the support push rods 83. Considering the stability of the structure and the obvious shock-absorbing effect, in some embodiments, the number of the support push rods 83 is at least two, and the cross-sectional area of ​​each support push rod 83 is equal. In this way, when a collision occurs, the pressure transmitted by the fluid medium in the hydraulic cylinder 84 is the same, which can play a better joint shock-absorbing role.

[0067] In addition, if Fig.11 and Fig.12 As shown, in some embodiments, the box body 2 is slidably connected to the installation box 1 , a support rod 91 and a second elastic member 92 are connected between the box body 2 and the installation box 1 , and a fracture groove 911 is provided on the side of the support rod 91 .

[0068] That is to say, in this embodiment, the support rod 91 and the second elastic member 92 form a second impact absorbing mechanism for absorbing the energy generated during the collision and playing a buffering role. Since the side of the support rod 91 is provided with a fracture groove 911, when a collision occurs, the fracture groove 911 can cause the support rod 91 to break, so that the second elastic member 92 plays a buffering role. Under normal circumstances, the support rod 91 is connected between the box body 2 and the installation box 1, and the relative movement between the installation box 1 and the box body 2 can be limited by the support rod 91. In some embodiments, the box body 2 is movably inserted into the installation box 1.

[0069] In some embodiments, the second elastic member 92 is a compression spring, and under normal circumstances, the second elastic member 92 is in a stretched state. In this way, when the support rod 91 breaks, the elastic force of the second elastic member 92 is used to drive the box body 2 to slide relative to the installation box 1, thereby playing a better buffering role.

[0070] In some embodiments, the second elastic member 92 is sleeved on the outer periphery of the support rod 91. This is beneficial to improve the stability of the second elastic member 92 and prevent it from tilting.

[0071] Below Figure 1-Figure 12 Taking the structure of the energy absorbing and anti-collision device for a maglev train as an example, its working principle is introduced.

[0072] During the travel of the maglev train 10 equipped with the energy absorption and collision avoidance device for maglev trains, the detection member 3 is used to monitor in real time whether there is an obstacle in front of the maglev train 10; when the detection member 3 detects that there is an obstacle in front of the maglev train 10, the limiting member 72 is actuated to release the limiting of the mounting member 71, so that the mounting member 71 drives the rotating wheel 74 to contact the ground under the action of the first elastic member 73, so that the rotating wheel 74 rotates, and then the generator 75 generates electricity, and the electric energy generated by the generator 75 will be stored in the battery 76, and then the battery 76 will stably output the electric energy to the rotating drive mechanism 6, so that the rotating drive mechanism 6 drives the turntable 5 to rotate periodically, so that the electromagnet 4 always maintains mutual repulsion and adsorption with the rail electromagnet 101 set on the train track, so that the maglev train 10 slowly reduces the speed, leaving more reaction time for the driver. When a collision occurs, the anti-collision beam 82 will be subjected to force first. At this time, the support rod 91 will break first due to the fracture groove 911 provided therein. Then the box body 2 will slide along the mounting box 1, and the second elastic member 92 will first absorb the kinetic energy of the collision. When the second elastic member 92 reaches the compression limit, the support push rod 83 will be compressed by force to further absorb the kinetic energy of the collision, thereby further effectively providing time for the driver to brake.

[0073] In addition to the above-mentioned energy absorption and anti-collision device for maglev trains, the present invention also provides a maglev train 10 including the energy absorption and anti-collision device for maglev trains disclosed in the above-mentioned embodiment. For the structures of other parts of the maglev train 10, please refer to the relevant technology and will not be repeated in this article.

[0074] The key point of this embodiment is that the maglev train 10 includes the energy absorbing and anti-collision device for maglev trains disclosed in the above embodiment, and has the same beneficial effects as the above energy absorbing and anti-collision device for maglev trains, which will not be repeated here.

[0075] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
