Description

Technical Field

[0001] This invention relates to the field of van accessories technology, specifically to a van interlocking device. Background Technology

[0002] Wing-door vans, also known as special vehicles with openable side wings, are widely favored by logistics companies due to their advantages such as fast loading and unloading speed, high efficiency, and the ability to load and unload from the side.

[0003] However, in practical applications, due to the driver's carelessness, there are occasional cases where the engine is started directly without closing the wing door, which not only easily damages the wing door, but also easily leads to various safety accidents. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of this invention is to provide a van interlocking device so that the vehicle engine cannot be started when the wing door is not fully closed, thereby avoiding accidents caused by the wing door not being closed.

[0049] like Figure 1-4 As shown, the present invention provides a box truck interlocking device, including a first mounting base 100, a second mounting base 200, a locking pin 300, a drive assembly, and a control assembly.

[0050] The first mounting base 100 is mounted on the carriage and fixedly connected to the carriage. The second mounting base 200 is mounted on the wing door and fixedly connected to the wing door. A locking hole 210 is provided on the side of the second mounting base 200 facing the first mounting base 100. A locking pin 300 is adapted to the locking hole 210 and is installed inside the first mounting base 100. The locking pin 300 has a first working position A extending beyond the side wall of the first mounting base 100 and a second working position A retracted into the side wall of the first mounting base 100. Specifically, when the locking pin 300 is in the first working position A, the locking pin 300 extends beyond the side wall of the first mounting base 100, so that the locking pin 300 can be inserted into the locking hole 210, thereby achieving the purpose of locking the wing door; when the locking pin 300 is in the second working position A, the locking pin 300 retracts into the side wall of the first mounting base 100, so that the locking pin 300 is pulled out from the locking hole 210, thereby achieving the purpose of unlocking the wing door.

[0051] A drive assembly is mounted on the first mounting base 100. The drive assembly drives the locking pin 300 to reciprocate linearly between a first working position A and a second working position A. A control assembly is used to connect the starting circuit of the vehicle engine when the locking pin 300 is in the first working position A, and to disconnect the starting circuit of the vehicle engine when the locking pin 300 is in the second working position A, thereby achieving the purpose of starting the vehicle only when the wing door is locked.

[0052] In one embodiment, the drive assembly includes a motor 410, a screw 420, and a first slider 430.

[0053] The motor 410 is installed inside the first mounting base 100 and fixedly connected to the first mounting base 100. The screw 420 is installed inside the first mounting base 100 and rotatably connected to the first mounting base 100. The power input end of the screw 420 is drively connected to the power output shaft of the motor 410. Specifically, a third gear 440 is fixedly sleeved on the power output shaft of the motor 410, and a fourth gear 450 is fixedly sleeved on the screw 420. The third gear 440 and the fourth gear 450 mesh with each other.

[0054] The first slider 430 is installed inside the first mounting base 100 and is slidably connected to the first mounting base 100. The first slider 430 is sleeved on the screw 420 and threadedly connected to the screw 420. The first slider 430 is fixedly connected to the end of the locking pin 300 facing the first mounting base 100. The first slider 430 has a first working position B that drives the locking pin 300 to a first working position A and a second working position B that drives the locking pin 300 to a second working position A. The first slider 430 can reciprocate linearly between the first working position B and the second working position B.

[0055] In use, the motor 410 drives the screw 420 to rotate in either the forward or reverse direction, thereby driving the first slider 430 to reciprocate linearly between the first working position B and the second working position B. Specifically, when the motor 410 drives the screw 420 to rotate in the forward direction, the screw 420 drives the first slider 430 to move from the second working position B to the first working position B, thereby driving the locking pin 300 to the first working position A, and thus locking the wing door; when the motor 410 drives the screw 420 to rotate in the reverse direction, the screw 420 drives the first slider 430 to move from the first working position B to the second working position B, thereby driving the locking pin 300 to the second working position A, and thus unlocking the wing door.

[0056] The drive components of this structure are simple in structure, reasonable in design, and easy to operate.

[0057] In one embodiment, the control component includes a first gear 501, a first rack 502, and a second rack 503.

[0058] The first gear 501 is installed in the second mounting base 200 and is rotatably connected to the second mounting base 200. The first rack 502 is installed on the side of the locking pin 300 facing the first gear 501 and can move with the movement of the locking pin 300, and the second rack 503 can drive the first gear 501 to rotate.

[0059] The second rack 503 is installed inside the first mounting base 100 and is slidably connected to the first mounting base 100. The second rack 503 is installed on the side of the first gear 501 away from the first rack 502 and meshes with the first gear 501. A first electrode 513 for controlling the on / off state of the starting circuit is fixedly installed on the second rack 503. The second rack 503 has a first working position C for connecting the starting circuit and a second working position C for disconnecting the starting circuit. The second rack 503 can reciprocate linearly between the first working position C and the second working position C.

[0060] In use, as the locking pin 300 moves from the second working position A to the first working position A, the first rack 502 drives the first gear 501 to rotate. Since the first gear 501 meshes with the second rack 503, when the first gear 501 rotates, it will drive the second rack 503 to move, thereby driving the second rack 503 from the second working position C to the first working position C, thus achieving the purpose of connecting the start circuit.

[0061] The control components of this structure are simple in structure and reasonable in design. The purpose of connecting the start-up circuit is achieved only when the first slider 430 is moved from the second working position B to the first working position B when the wing door is closed.

[0062] However, if the first gear 501 is engaged with both the first rack 502 and the second rack 503, then during the process of unlocking the wing door—that is, during the process of the first slider 430 driving the locking pin 300 from the first working position A to the second working position A—the first rack 502 will immediately drive the second rack 503 to the second working position C via the first gear 501. Therefore, during the process of unlocking the wing door, if the motor 410 malfunctions and cannot drive the locking pin 300 back to the first working position A, the vehicle will also be unable to start. To solve the above problem, in one embodiment, the control assembly further includes a second gear 504, a first permanent magnet 505, a first electromagnet 506, a second slider 507, a first elastic element 508, and a second elastic element (not shown in the figures).

[0063] The second gear 504 is connected to the first gear 501 via a ratchet structure (not shown in the attached figure), and the second gear 504 can mesh with the first rack 502. Specifically, both the second gear 504 and the first gear 501 are mounted on the drive shaft 516, and the second gear 504 is connected to the drive shaft 516 via the ratchet structure, while the first gear 501 is fixedly connected to the drive shaft 516. In use, during the process of inserting the locking pin 300 into the locking socket 210, the first rack 502 drives the second gear 504 to rotate, the second gear 504 drives the transmission shaft 516 to rotate through the ratchet mechanism, the transmission shaft 516 drives the first gear 501 to rotate, and the first gear 501 drives the second rack 503 to move from the second working position C to the first working position C, thereby achieving the purpose of connecting the start circuit; while during the process of pulling the locking pin 300 out of the locking socket 210, the first rack 502 drives the second gear 504 to rotate. Under the unidirectional transmission action of the ratchet structure, the second gear 504 cannot drive the transmission shaft 516 to rotate, thus it cannot drive the first gear 501 to rotate, and therefore cannot drive the second rack 503 to move, so that the second rack 503 will not immediately disconnect the start circuit.

[0064] The first permanent magnet 505 is disposed at the end of the second rack 503 facing the first mounting base 100. The first electromagnet 506 cooperates with the first permanent magnet 505. The first electromagnet 506 is mounted on the first mounting base 100, and the magnetic properties of the opposite side of the first electromagnet 506 and the first permanent magnet 505 are different. Therefore, when the first electromagnet 506 is energized, a magnetic attraction force is generated between the first electromagnet 506 and the first permanent magnet 505. Under the action of this magnetic attraction force, the second rack 503 is held in the first working position C.

[0065] The second slider 507 is installed inside the first mounting base 100. The second slider 507 is equipped with a second electrode 514 for controlling the on and off of the first electromagnet 506. The second slider 507 has a first working position D for energizing the first electromagnet 506 and a second working position D for de-energizing the first electromagnet 506. The second slider 507 can reciprocate between the first working position D and the second working position D.

[0066] The two ends of the first elastic element 508 are respectively connected to the second rack 503 and the second mounting base 200, and in its natural state, the first elastic element 508 has a tendency to move the second rack 503 from the first working position C to the second working position C. When the first electromagnet 506 is de-energized, under the action of the elastic force of the first elastic element 508, the first elastic element 508 drives the second rack 503 and the first working position C to the second working position C, thereby achieving the purpose of disconnecting the starting circuit. Preferably, the first elastic element 508 is a spring.

[0067] The two ends of the second elastic member are respectively connected to the second slider 507 and the first mounting base 100, and in its natural state, the second elastic member has a tendency to move the second slider 507 from the second working position D to the first working position D.

[0068] Specifically, when the first slider 430 moves from the first working position B to the second working position B, the first slider 430 can drive the second slider 507 from the first working position D to the second working position D.

[0069] Specifically, the first end of the second slider 507 is hinged to the first mounting base 100, and the second end of the second slider 507 can reciprocate between the first working position D and the second working position D. The second elastic element is a torsion spring, which is installed at the hinge center of the second slider 507. The two ends of the torsion spring are respectively connected to the second slider 507 and the first mounting base 100, and in its natural state, the torsion spring has a tendency to make the second slider 507 swing from the second working position D to the first working position D.

[0070] In use, during the process of the first slider 430 moving from the first working position B to the second working position B, the first slider 430 abuts against the second slider 507, thereby driving the second slider 507 to move from the first working position D to the second working position D, thereby disconnecting the first electromagnet. Under the action of the elastic force of the first elastic member 508, the first elastic member 508 drives the second rack 503 and the first working position C to the second working position C, thereby achieving the purpose of disconnecting the starting circuit.

[0071] During the process of the first slider 430 moving from the second working position B to the first working position B, the first slider 430 separates from the second slider 507. Under the action of the elastic force of the second elastic element, the second slider 507 moves from the second working position D to the first working position D, thereby energizing the first electromagnet 506. Under the action of the magnetic attraction between the first electromagnet 506 and the first permanent magnet 505, the second rack 503 is held in the first working position C.

[0072] The control components of this structure are simple and reasonably designed. During the process of unlocking the wing door, even if the locking pin 300 cannot be driven back to the first working position A due to a malfunction of the motor 410, the starting circuit will not be immediately disconnected, thus achieving the purpose of continuing to start the vehicle. Only when the first slider 430 moves to drive the second slider 507 from the first working position D to the second working position D to disconnect the first electromagnet 506 will the vehicle be unable to start.

[0073] However, during the locking process of the wing door, if the motor 410 malfunctions and cannot drive the locking pin 300 to the first working position A, the vehicle will also be unable to start. To solve the above problem, in one embodiment, the control assembly further includes a second permanent magnet 509, a second electromagnet 510, a third elastic element 511, a third slider 512, and a fourth elastic element (not shown in the figure).

[0074] The second permanent magnet 509 is fixedly embedded in the end of the first rack 502 facing the second mounting base 200. The second electromagnet 510 cooperates with the second permanent magnet 509. The second electromagnet 510 is mounted on the second mounting base 200, and the magnetic properties of the opposite side of the second permanent magnet 509 and the second electromagnet 510 are different. Therefore, when the second electromagnet 510 is energized, a magnetic attraction force is generated between the second electromagnet 510 and the second permanent magnet 509. Under the action of this magnetic attraction force, the first rack 502 will be driven to move.

[0075] The first rack 502 is slidably connected to the locking pin 300, and the first rack 502 can reciprocate linearly between the first working position E and the second working position E along the length direction of the locking pin 300. The two ends of the third elastic member 511 are respectively connected to the first rack 502 and the locking pin 300, and in its natural state, the third elastic member 511 has a tendency to move the first rack 502 away from the second mounting base 200.

[0076] The third slider 512 is installed inside the second mounting base 200. The third slider 512 is equipped with a third electrode 515 for controlling the energization of the first electromagnet 506. The third slider 512 has a first working position F for energizing the second electromagnet 510 and a second working position F for de-energizing the second electromagnet 510. The third slider 512 can reciprocate between the first working position F and the second working position F.

[0077] The two ends of the fourth elastic member are respectively connected to the third slider 512 and the second mounting base 200, and in its natural state, the fourth elastic member has a tendency to move the third slider 512 from the first working position F to the second working position F.

[0078] Specifically, when the locking pin 300 moves from the second working position A to the first working position A, the locking pin 300 can drive the third slider 512 from the second working position F to the first working position F.

[0079] Specifically, the first end of the third slider 512 is hinged to the second mounting base 200, and the second end of the third slider 512 can reciprocate between the first working position F and the second working position F. The fourth elastic element is a torsion spring, which is installed at the hinge center of the third slider 512. The two ends of the torsion spring are respectively connected to the third slider 512 and the second mounting base 200, and in its natural state, the torsion spring has a tendency to make the third slider 512 swing from the first working position F to the second working position F.

[0080] In use, as the locking pin 300 moves from the second working position A to the first working position A and is inserted into the locking socket 210, the locking pin 300 will abut against the third slider 512, thereby driving the third slider 512 to move from the second working position F to the first working position F. This energizes the second electromagnet 510. Under the magnetic attraction between the second electromagnet 510 and the second permanent magnet 509, the first rack 502 is driven to move closer to the first mounting base 100. This causes the first rack 502 to drive the second gear 504 to rotate. The second gear 504 drives the transmission shaft 516 to rotate through the ratchet structure. The transmission shaft 516 drives the first gear 501 to rotate. The first gear 501 drives the second rack 503 to move from the second working position C to the first working position C, thereby achieving the purpose of connecting the start circuit.

[0081] During the process of the locking pin 300 being pulled out from the first working position A to the second working position A and from the locking hole 210, the locking pin 300 separates from the third slider 512. Under the action of the elastic force of the fourth elastic element, the third slider 512 moves from the first working position F to the second working position F, thereby de-energizing the second electromagnet 510. Under the action of the elastic force of the third elastic element 511, the first rack 502 returns to its original position.

[0082] The control components of this structure can achieve the purpose of connecting the starting circuit when the locking pin 300 moves to drive the third slider 512 from the second working position F to the first working position F. Therefore, even if the locking pin 300 cannot be driven to the first working position A due to a malfunction of the motor 410 during the locking of the wing door, the vehicle can still be started.

[0083] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
