Description

Technical Field

[0001] This invention relates to the field of chassis mounting technology, specifically to a structure for a charging chassis mounting for rail vehicles and its charging chassis. Background Technology

[0002] Railcars, also known as rail flatcars, electric flatcars, rail flatcars, rail flatcars, electric cars, trolleys, crosscars, ground crawlers, etc., are a type of rail-mounted electric transport vehicle used within factories. First, they are electric vehicles that operate automatically under electric drive. Second, they are vehicles that run on rails, which need to be laid on the ground. The rails are generally I-shaped surface contact rails.

[0003] For example, Chinese patent CN217730449U discloses an electric railcar for cross-workshop use, which includes an electrical control system, a left-running drive motor and a right-running drive motor. The electrical control system is electrically connected to the left-running drive motor and the right-running drive motor respectively, and the left-running drive motor and the right-running drive motor are respectively connected to the corresponding drive wheel.

[0004] However, the above solution has the following shortcomings: Since railcars are mostly used in industrial production, there are many large parts in industrial production. Since the charging box for railcars is mostly located at the bottom of the railcar, when large parts in the external environment roll onto the railcar's track, the charging box located at the bottom of the railcar may collide with the large parts, causing damage to the charging box and making the railcar unusable. To address this, we have proposed a charging box mounting structure for railcars and its charging box. Summary of the Invention

[0009] Preferably, the limiting mechanism includes a T-shaped limiting rod, which is engaged in the limiting hole. The engaging end of the T-shaped limiting rod is inclined.

A second spring is fixedly connected to the upper end of the U-shaped locking rod, and the other end of the second spring is fixedly connected to the sliding groove. The end of the U-shaped locking rod away from the locking hole extends out of the hanging base plate.

[0011] Preferably, the fixing mechanism includes a T-shaped fixing rod, the locking end of which is inclined, the T-shaped fixing rod is movably connected to a U-shaped connecting block, a limiting block is sleeved on the outside of the T-shaped fixing rod, the limiting block slides in a relief cavity, the relief cavity is opened in the U-shaped connecting block, and a third spring is sleeved on the outside of the T-shaped fixing rod, one end of which is fixedly connected to the limiting block and the other end of which is fixedly connected to the relief cavity.

[0012] Preferably, the triggering mechanism includes a T-shaped trigger rod, which is snapped into the connecting hole and slidably connected to a sliding cavity located within a connecting tube.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: When a large part in the external environment collides with the charging box body, the limiting mechanism will disengage from the limiting of the charging box body. At this time, the charging box body will quickly move backward away from the large part to prevent the charging box body from being crushed and damaged by the large part. When the charging box body moves to the end of the T-slot, the snap-fit ​​structure is canceled, and the two sets of U-shaped protective covers will rotate and move downward. When the two sets of U-shaped protective covers move to the final position, the connecting ring will snap together with the U-shaped connecting block, so that the two sets of U-shaped protective covers are fixed. The two sets of U-shaped protective covers can further protect the charging box body and prevent the charging box from becoming unusable due to collisions with objects in the external environment.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-6 The present invention provides a technical solution:

[0026] Example 1:

[0027] A charging station mounting structure for a railcar includes a mounting plate 1. Mounting screws 10 are provided around the perimeter of the mounting plate 1. The mounting plate 1 is installed to the lower end of the railcar body 37 using the mounting screws 10. After installation, it is connected to the charging station body 22 via an external power supply to charge the railcar body 37. A connecting plate 14 is provided on the lower side of the mounting plate 1. The lower end of the connecting plate 14 is fixedly connected to the charging station body 22, and two sets of T-blocks 7 are fixedly connected to the upper end of the connecting plate 14. The T-blocks 7 are movably connected to the T-shaped blocks. T-shaped groove 4 is opened in the lower end of the hanging base plate 1. Push spring 34 is fixedly connected in T-shaped groove 4. The other end of push spring 34 is fixedly connected to T-shaped block 7. Limiting holes 6 are opened in the opposite surfaces of the two sets of T-shaped blocks 7. The limiting holes 6 are set in an inclined shape. A limiting mechanism is engaged in the limiting holes 6. Since the elastic force of the first spring 5 in the limiting mechanism is greater than the elastic force of push spring 34, the T-shaped block 7 can be limited and fixed by the limiting mechanism when the charging box body 22 is not squeezed or collided.

[0028] Two sets of U-shaped protective covers 21 are provided on the rear side of the charging box body 22. The U-shaped protective covers 21 are movably connected to the lower end of the hanging base plate 1. The upper end of the U-shaped protective cover 21 has a snap-fit ​​hole 20, and a snap-fit ​​mechanism is snapped in the snap-fit ​​hole 20. The lower end of the U-shaped protective cover 21 is fixedly connected to a connecting pipe 28. A T-shaped connecting rod 29 is slidably connected in the connecting pipe 28. A transmission spring 23 is fixedly connected in the connecting pipe 28. The other end of the transmission spring 23 is fixedly connected to the T-shaped connecting rod 29. The left end of the T-shaped connecting rod 29, away from the transmission spring 23, extends out of the connecting pipe 28 and is fixedly connected to the connecting ring 16. The right end of the T-shaped connecting rod 29, away from the transmission spring 23, extends out of the connecting pipe 28 and is fixedly connected to the U-shaped connecting block 30. A fixing mechanism is provided in the U-shaped connecting block 30. A connecting hole 24 is provided in the T-shaped connecting rod 29, and a trigger mechanism is snapped in the connecting hole 24.

[0029] Example 2:

[0030] Based on Embodiment 1, in order to enable the two sets of U-shaped protective covers 21 to move downwards to protect the charging chassis body 22 when it moves to the rear end, the limiting mechanism includes a T-shaped limiting rod 3. The T-shaped limiting rod 3 is engaged in the limiting hole 6, and the engaging end of the T-shaped limiting rod 3 is inclined. The end of the T-shaped limiting rod 3 away from the limiting hole 6 is movably connected to the connecting cavity 2. The connecting cavity 2 is opened in the hanging plate 1, and a first spring 5 is fixedly connected in the connecting cavity 2. The other end of the first spring 5 is fixedly connected to the T-shaped limiting rod 3. When large parts... After colliding with the charging chassis body 22, the charging chassis body 22 moves backward under the impact of the large parts. The backward movement of the charging chassis body 22 causes the two sets of T-shaped blocks 7 connected to its upper end to move outward along the T-shaped groove 4. Since the T-shaped limiting rod 3 and the limiting hole 6 are both set in an inclined position, the T-shaped limiting rod 3 moves into the connecting cavity 2 under the compression in the limiting hole 6. When the T-shaped limiting rod 3 completely disengages from the limiting hole 6, the charging chassis body 22 will move backward quickly under the elastic force of the pushing spring 34.

[0031] The latching mechanism includes a U-shaped latching rod 13. One end of the U-shaped latching rod 13 is latched into the latching hole 20, and the U-shaped latching rod 13 is movably connected to the sliding groove 9. The sliding groove 9 is opened in the hanging plate 1. A second spring 8 is fixedly connected to the upper end of the U-shaped latching rod 13, and the other end of the second spring 8 is fixedly connected to the sliding groove 9. The end of the U-shaped latching rod 13 away from the latching hole 20 extends out of the hanging plate 1. When the charging box body 22 drives the connecting plate 14 to move, it will squeeze the extended end of the U-shaped latching rod 13. The U-shaped latching rod 13 moves upward so that its other end can be disengaged from the latching hole 20. When the U-shaped latching rod 13 is completely disengaged from the latching hole 20, under the elastic force of the torsion spring 18, the two sets of U-shaped protective covers 21 will move inward quickly. When the two sets of U-shaped protective covers 21 are put together, they can further protect the charging box body 22.

[0032] The fixing mechanism includes a T-shaped fixing rod 32, the snap-fit ​​end of which is inclined. The T-shaped fixing rod 32 is movably connected within a U-shaped connecting block 30. A limiting block 36 is sleeved on the outer side of the T-shaped fixing rod 32, and the limiting block 36 slides within a relief cavity 31, which is located within the U-shaped connecting block 30. A third spring 33 is sleeved on the outer side of the T-shaped fixing rod 32, one end of which is fixedly connected to the limiting block 36, and the other end is fixedly connected to the relief cavity 31. The triggering mechanism includes a T-shaped trigger rod 15. The T-shaped trigger rod 15 is snapped into the connecting hole 24, and the T-shaped trigger rod 15 is slidably connected into the sliding cavity 27, which is opened in the connecting tube 28. The end of the T-shaped trigger rod 15 away from the connecting hole 24 is fixedly connected to the traction rope 25, and the other end of the traction rope 25 is fixedly connected to the T-shaped compression rod 12. The T-shaped compression rod 12 is movably connected into the U-shaped protective cover 21. A return spring 26 is sleeved on the outside of the traction rope 25. One end of the return spring 26 is fixedly connected to the sliding cavity 27, and the other end is fixedly connected to the T-shaped trigger rod 15.

[0033] A connecting spring 11 is sleeved on the outside of the T-shaped extrusion rod 12. One end of the connecting spring 11 is fixedly connected to the U-shaped protective cover 21, and the other end is fixedly connected to the baffle 35. The baffle 35 is fixedly sleeved on the outside of the T-shaped extrusion rod 12. Connecting shafts 17 are fixedly connected to both sides of the U-shaped protective cover 21. The connecting shafts 17 are movably connected to the relief groove 19. The relief groove 19 is opened in the lower end of the hanging base plate 1. A torsion spring 18 is sleeved on the outside of the connecting shaft 17. One end of the torsion spring 18 is fixedly connected to the relief groove 19, and the other end is fixedly connected to the U-shaped protective cover 21.

[0034] Furthermore, to achieve the above objectives, the present invention also provides a charging housing, including the aforementioned rail vehicle charging housing mounting structure.

[0035] Working principle: During use, the mounting plate 1 is installed to the lower end of the railcar body 37 by the mounting screw 10. After installation, it is connected to the charging box body 22 by an external power supply to charge the railcar body 37. When a large part collides with the charging box body 22, the charging box body 22 moves backward under the impact of the large part. The backward movement of the charging box body 22 drives the two sets of T-shaped blocks 7 connected to its upper end to move outward along the T-shaped groove 4. Since the T-shaped limiting rod 3 and the limiting hole 6 are both set in an inclined position, the T-shaped limiting rod 3 moves into the connecting cavity 2 under the compression in the limiting hole 6. When the T-shaped limiting rod 3 completely disengages from the limiting hole 6, the charging box body 22 will move backward quickly under the elastic force of the pushing spring 34.

[0036] Since the U-shaped latching rod 13 extends out of the hanging plate 1 at an angle, the charging box body 22, along with the connecting plate 14, will press the extended end of the U-shaped latching rod 13 during the movement. The U-shaped latching rod 13 moves upward, allowing its other end to disengage from the latching hole 20. When the U-shaped latching rod 13 is completely disengaged from the latching hole 20, the two sets of U-shaped protective covers 21 will move inward rapidly under the elastic force of the torsion spring 18. The two sets of U-shaped protective covers 21, when put together, can further protect the charging box body 22. At the same time, as the U-shaped protective cover 21 moves downward, the T-shaped pressing rod 12 located inside the U-shaped protective cover 21 will come into contact with the charging box body 22. As the U-shaped protective cover 21 moves inward continuously, the T-shaped pressing rod 12 is pushed outward. The outward movement of the T-shaped pressing rod 12 drives the traction rope 25 to move synchronously. The movement of the traction rope 25 drives the T-shaped trigger rod 15 to move and disengage from the connecting hole 24.

[0037] When the T-shaped trigger rod 15 is completely disengaged from the connecting hole 24, the T-shaped connecting rod 29 located in the connecting tube 28 moves outward rapidly under the elastic force of the transmission spring 23. When the connecting ring 16 connected to the left T-shaped connecting rod 29 enters the U-shaped connecting block 30, the T-shaped fixing rod 32 located in the U-shaped connecting block 30 is squeezed outward by the connecting ring 16. The outward movement of the T-shaped fixing rod 32 drives the limiting block 36 to move synchronously. The limiting block 36 moves along the relief cavity 31, causing the third spring 33 to be compressed. When the connecting ring 16 is completely entered into the U-shaped connecting block 30, the T-shaped fixing rod 32 is engaged with the connecting ring 16 under the elastic force of the third spring 33. At this time, the two sets of T-shaped connecting rods 29 are fixed together. The two sets of T-shaped connecting rods 29 being fixed together prevents the two closed U-shaped protective covers 21 from opening under the action of external force.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
