DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] like Figure 1 As shown, a collision energy absorption power generation mechanism includes a buffer cover 1 and a collision base 2 that slide against each other, an energy absorption buffer spring 73 arranged between the buffer cover 1 and the collision base 2, and at least one power generation component.

[0033] like Figure 1 , 2As shown in Figures 3 and 4, the buffer cover 1, the collision base 2 and the energy absorbing buffer spring 73 constitute an energy absorbing structure in the prior art, and due to the existence of the energy absorbing buffer spring 73, the buffer cover 1 can be reciprocated in the direction toward or away from the collision base 2 when and after being subjected to external force. Theoretically, no matter whether the structure of the buffer cover 1 and the collision base 2 is a rectangular plate, a block structure, a strip structure, a circular plate or other special-shaped structures, as long as the buffer cover 1 can be reciprocated in the direction toward or away from the collision base 2. In this embodiment, in order to make the matching connection between the buffer cover 1, the collision base 2 and the energy absorbing buffer spring 73 more stable, the buffer cover 1 includes a collision plate 11 and a sliding plate 12 that are perpendicular to each other, and the collision base 2 includes a fixed plate 22 and a limit plate 21 that are perpendicular to each other. The collision plate 11 and the fixed plate 22 are arranged in parallel and at intervals, the energy absorbing buffer spring 73 is arranged between the fixed plate 22 and the collision plate 11, the sliding plate 12 and the limit plate 21 are arranged in parallel and at intervals, and the sliding plate 12 and the limit plate 21 are respectively provided with relatively protruding limit blocks 13, and the two limit blocks 13 are arranged at intervals along the moving direction of the collision plate 11 to limit the moving position of the sliding plate 12. Figure 2 , 3 As shown, the buffer cover 1 and the collision base 2 are roughly in the shape of a figure 7. This structure can facilitate the sliding limit of the buffer cover 1 and the collision base 2, prevent the buffer cover 1 from being separated from the collision base 2 under the action of the energy-absorbing buffer spring 73, and limit the freedom of the buffer cover 1 along the collision direction; at the same time, this layout method can make a large enough gap between the fixed plate 22 and the collision plate 11 for installing the energy-absorbing buffer spring 73 and the power generation component. The limit block 13 can limit the maximum collision force of the buffer cover 1 and protect the power generation device from being damaged in excessive collision. At the same time, the limit block 13 can also prevent the power generation device from excessively rebounding after the collision, thereby ensuring the stability of the power generation device.

[0034] In order to enable the energy-absorbing buffer spring 73 to achieve energy absorption and buffering while also positioning the connection between the buffer cover 1 and the collision base 2, in the present embodiment, the energy-absorbing buffer spring 73 is arranged in the sleeve 7, one end of the sleeve 7 is fixed to the fixed plate 22, and the other end of the sleeve 7 is provided with a plug-in compression rod 9, the compression rod 9 is fixed to the collision plate 11, and the movement of the collision plate 11 drives the compression rod 9 to move and squeeze the energy-absorbing buffer spring 73. The energy-absorbing buffer spring 73, the sleeve 7 and the compression rod 9 constitute a spring telescopic rod structure, which can realize the positioning connection between the buffer cover 1 and the collision base 2, and ensure that the collision plate 11 moves back and forth in a horizontal or vertical manner toward or away from the fixed plate 22. In order to further increase the stability between the buffer cover 1 and the collision base 2, such as Figure 2 , 3As shown, in this embodiment, two energy absorbing buffer springs 73 are arranged at intervals, each energy absorbing buffer spring 73 is provided with a sleeve 7 and a compression rod 9 for use with them, and the power generation assembly is arranged between the two energy absorbing buffer springs 73. The two energy absorbing buffer springs 73 are used to increase the stability of the buffer cover 1 and the collision base 2 when in use. At the same time, a limit block 91 protruding outward can be provided on the compression rod 9, and a slide groove 71 that slidably cooperates with the limit block 91 can be provided inside the sleeve 7. The cooperation between the limit block 91 and the slide groove 71 can ensure that the compression rod 9 slides back and forth in the horizontal or vertical direction.

[0035] In order to detect the collision pressure, in this embodiment, Figure 2 As shown, the pressure display assembly is also included, and the pressure display assembly includes a pressure sensor 72 arranged between the fixing plate 22 and the energy absorbing buffer spring 73 and a pressure display 10 which is electrically connected to the pressure sensor 72. The pressure display 10 transmits signals through the pressure display 10 harness to display the pressure value of the compressible energy absorbing buffer spring 73 inside the sleeve 7, and can feed back the collision depth to the driver, so as to ensure that the driver obtains the collision information, so as to facilitate the driver to make judgments, avoid being in an environment with excessive collision external force for a long time, and shorten the service life of the collision energy absorbing mechanism.

[0036] In order to realize the conversion of collision energy, the utility model is provided with a power generation component between the buffer cover 1 and the collision base 2. The number of the power generation components can be determined according to the installation space between the buffer cover 1 and the collision base 2. In the utility model, four power generation components are provided, and the structure of each power generation component is the same. Specifically, Figure 1As shown, the power generation assembly includes an explosion-proof motor 4, a gear member installed in cooperation with the input shaft 41 of the explosion-proof motor 4, and a rack 14 used in cooperation with the gear member. The explosion-proof motor 4 is fixed to the collision base 2, and the rack 14 is fixed to the buffer cover 1. The rack 14 moves unidirectionally toward or away from the collision base 2 with the buffer cover 1, driving the gear member to drive the input shaft 41 to rotate unidirectionally to generate electricity. The explosion-proof motor 4 adopts an explosion-proof explosion-proof motor 4, and the explosion-proof motor 4 is fixed to the fixing plate 22 of the collision base 2 through the fixing seat 6; the explosion-proof motor 4 includes a housing, a stator, a rotor, a brush, etc. The principle of the explosion-proof motor 4 is that the rotor shaft of the explosion-proof motor 4 rotates, so that the rotor can rotate in the stator, and the movement of cutting the magnetic lines of force is performed, thereby generating an induced potential and realizing power generation. The explosion-proof motor 4 is a prior art, and its power generation principle is that the input shaft 41 of the explosion-proof motor 4 rotates, and the purpose of power generation is achieved through the various components of the explosion-proof motor 4. The gear part is equivalent to a gear with a one-way clutch, and the gear can only drive the input shaft 41 of the explosion-proof motor 4 to rotate when it moves forward or backward to achieve the purpose of generating electricity. Correspondingly, the four racks 14 are grouped in pairs, and the two racks 14 in each group are respectively located on both sides of the vertical plate 15 extending from the buffer cover 1, and the four racks 14 are respectively meshed with the four external gears 3, and the movement of the racks 14 drives the external gears 3 to rotate.

[0037] In the prior art, a ratchet pawl assembly of a general structure can realize unidirectional rotation of the shaft. However, the ratchet pawl assembly in the prior art has the problem of loose fit. Therefore, the utility model improves the existing ratchet pawl assembly. Specifically, Figure 4-9As shown, the gear member includes an outer gear 3 and a ratchet 31 and a limiting structure 321 which are coaxially arranged. The outer gear 3 is meshed with the rack 14. The ratchet 31 and the input shaft 41 are coaxially fixed. The limiting structure 321 limits the input shaft 41 to rotate in one direction. The limiting mechanism includes a plurality of ratchet pawls 311 and limiting tooth grooves 32 which are arranged along the circumference of the ratchet 31. The plurality of ratchet pawls 311 are all hinged to the ratchet 31, and the plurality of ratchet pawls 311 rotate simultaneously on the ratchet 31 in a forward direction or a reverse direction. The limiting tooth grooves 32 are detachably fixed to the outer gear 3. The limiting tooth grooves 32 are sleeved outside the plurality of ratchet pawls 311, and the limiting tooth grooves 32 are rotationally connected to the ratchet 31. The rotation of the outer gear 3 drives the limiting tooth grooves 32 to rotate. The rotation of the limiting tooth grooves 32 drives the plurality of ratchet pawls 311 to rotate simultaneously along the ratchet 31 so that the ratchet 31 is fixedly connected or rotationally connected to the outer gear 3. The ratchet 31 and the input shaft 41 are fixed, and the multiple pawls 311 arranged on the ratchet 31 are hingedly arranged with the ratchet 31. The limiting tooth groove 32 is sleeved outside the multiple pawls 311. Due to the structural limitation of the limiting tooth groove 32 and the pawl 311, when the limiting tooth groove 32 rotates counterclockwise, the multiple pawls 311 will rotate along the ratchet 31 and will not block the rotation of the limiting tooth groove 32; when the limiting tooth groove 32 rotates clockwise, due to the structural limitation, the multiple pawls 311 and the limiting tooth groove 32 are locked. At this time, the rotation of the limiting tooth groove 32 drives the ratchet 31 to rotate, the rotation of the ratchet 31 drives the input shaft 41 to rotate, and the rotation of the input shaft 41 drives the explosion-proof motor 4 to generate electricity. Since the limiting tooth groove 32 and the external gear 3 are fixed, the external gear 3 and the limiting tooth groove 32 rotate in the same direction. When setting the matching relationship between the rack 14 and the outer gear 3, it can be set that the rack 14 drives the outer gear 3 to rotate counterclockwise when moving toward the collision base 2; it can also be set that the rack 14 drives the outer gear 3 to rotate counterclockwise when moving away from the collision base 2; thereby realizing that the rack 14 moves unidirectionally toward or away from the collision base 2 with the buffer cover 1, driving the gear member to drive the input shaft 41 to rotate unidirectionally to generate electricity.

[0038] In order to make the pawl 311 and the limiting tooth groove 32 cooperate smoothly, the pawl 311 needs to be reset while rotating along the ratchet wheel 31. Fig. 9 As shown, multiple mounting grooves for matching multiple pawls 311 are provided on the outer wall of the ratchet 31, and a torsion spring 314 is provided in each mounting groove, and the torsion spring 314 is fixed between the mounting groove and the corresponding pawl 311. The existence of the torsion spring 314 can achieve the fixed angle between the pawl 311 and the ratchet 31 in the absence of external force, and after the pawl 311 is subjected to an external force to change the angle between the pawl 311 and the ratchet 31, the pawl 311 can be reset when the external force disappears, thereby preventing the pawl 311 from deviating from the original position.

[0039] To facilitate the matching connection between the ratchet wheel 31 and the limiting tooth groove 32, as shown in FIG. Figure 6-9As shown, the ratchet 31 and the limiting tooth groove 32 are limited and fixed by the extension block 312 on the ratchet 31, which is convenient for the removal of the limiting tooth groove 32 and the replacement of the torsion spring 314; the limiting tooth groove 32 is rotatably connected to the ratchet 31 through the roller 313 (roller 313 bearing) and can realize independent movement.

[0040] The limiting tooth groove 32 is plugged and fixed with the external gear 3. Figure 5 , 6 As shown, the limiting tooth groove 32 includes a circular ring structure 322 and a limiting structure 321 protruding outward from the circular ring structure 322. A slot 33 matching the shape of the limiting tooth groove 32 is provided on the external gear 3. The limiting tooth groove 32 is clamped in the slot 33 to achieve a detachable fixed connection with the external gear 3, ensuring that the rotation of the external gear 3 can drive the limiting tooth groove 32 to rotate. When the external gear 3 and the limiting tooth groove 32 are plugged in, in order to ensure the stability of the connection, the two can be further fixed by gluing, or the two can be plugged in by interference fit, and can also be further fixed by welding. Of course, if the limiting tooth groove 32 and the external gear 3 can meet the connection requirements when plugged in, no further reinforcement treatment is required.

[0041] To facilitate the coaxial fixation of the ratchet 31 and the input shaft 41, as shown in FIG. Figure 5 As shown, a rotor gear 42 is provided on the input shaft 41, and the ratchet 31 is sleeved on the input shaft 41 and plugged with the rotor gear 42, and the rotation of the ratchet 31 drives the input shaft 41 to rotate. The rotor gear 42 is similar to a spline structure, which can realize the simultaneous rotation of the coaxially sleeved ratchet 31 and the input shaft 41.

[0042] In order to store the electric energy generated by the four explosion-proof motors 4, Figure 1 As shown, the utility model also includes an explosion-proof energy storage capacitor 5, which is connected to the explosion-proof motor 4 through a wiring harness. The explosion-proof energy storage capacitor 5 is an explosion-proof energy storage capacitor 5, which is equivalent to an energy storage power supply, and can power the warning lights and lighting lights of the shuttle car. While converting and collecting collision energy, it can also utilize electrical energy.

[0043] The utility model also provides a mining shuttle car, including the above-mentioned collision energy absorption and power generation mechanism, wherein the collision base 2 and the mining shuttle car body are fixed, and this fixing method can be installed with reference to the installation position of the energy absorption structure recorded in the patent application number CN202210174785.9 and the name of the mining shuttle car collision energy absorption structure (the collision base 2 is equivalent to the collision device base, and the buffer cover 1 is equivalent to the rubber bumper).

[0044] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the telecommunication connection is completed in the order of working between the electrical components. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0045] Principle of the utility model:

[0046] The collision energy absorption power generation mechanism is installed on the shuttle car. During the driving of the shuttle car, the buffer cover 1 encounters an obstacle and collides. The buffer cover 1 is forced to move toward the collision base 2, driving the four racks 14 to move. The movement of the racks 14 drives the outer gear 3 to rotate. If the outer gear 3 rotates clockwise at this time, the rotation of the outer gear 3 drives the limit tooth groove 32, the ratchet 31, and the input shaft 41 to rotate at the same time. The input shaft 41 is the rotor shaft of the explosion-proof motor 4. The rotation of the rotating shaft enables the rotor to rotate in the stator and cut the magnetic lines of force, thereby generating an induced potential and realizing the power generation of the explosion-proof motor 4; when the buffer cover 1 moves in the reverse direction under the action of the energy absorption buffer spring 73, it drives the rack 14 to move away from the collision base 2, and drives the outer gear 3 to rotate counterclockwise, then the input shaft 41 does not rotate, and the explosion-proof motor 4 does not generate electricity. On the contrary, when the rack 14 moves close to the collision base 2, it drives the outer gear 3 to rotate counterclockwise, then the input shaft 41 does not rotate, and the anti-explosion motor 4 does not generate electricity. When the rack 14 moves away from the collision base 2, the outer gear 3 moves clockwise, then the input shaft 41 rotates, and the anti-explosion motor 4 generates electricity, so that the rack 14 moves unidirectionally toward or away from the collision base 2 with the buffer cover 1, driving the gear member to drive the input shaft 41 to rotate unidirectionally to generate electricity.

[0047] The utility model adds a power generation component on the basis of the existing collision energy absorption structure, which can convert and collect the energy in the collision process, avoid energy waste, and at the same time use the collected electric energy for the shuttle car lighting, warning and other uses, thereby ensuring that the shuttle car has sufficient electric energy.

[0048] The mining shuttle car collision power generation structure manufactured using the technical solution of the utility model can be widely used to absorb energy through continuous collisions. The generated energy can be used in the vehicle's warning device or stored in an explosion-proof supercapacitor, thereby reducing energy waste and saving electric energy.
