Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors, in particular to a trackless machine head inductive deviation correction mechanism for sliding doors. Background Art

[0002] Electric sliding door is also known as "electric telescopic door" or "electric folding door". The electric sliding door is mainly composed of door body, drive and control system. The door body of the sliding door is made of high-quality aluminum alloy and ordinary square tube, and is hinged using the parallelogram principle, which is flexible and has a large telescopic stroke.

[0003] According to the public patent CN221779356U, a frame structure of an electric telescopic door belongs to the technical field of electric telescopic doors, including a fixed seat, a vehicle head is provided on one side of the fixed seat, a telescopic fence is provided on the vehicle head near one end of the fixed seat, a dual-axis motor is provided inside the fixed seat, a threaded rod is provided at the output end of the dual-axis motor, a threaded cylinder is provided on the surface of the threaded rod, a limit plate is provided at one end of the threaded cylinder, and the limit plate and the telescopic fence are connected by a limit slide rod. The utility model sets a sealing component. When the limit plate moves in the limit slide groove of the fixed seat, the sealing plates and slides on both sides of the limit slide groove slide in the cavity, and the extension and contraction of the spring make the abutment plate at one end of the sealing plate press against the side of the limit plate. The sealing plate can seal the limit slide grooves at both ends of the limit plate, and the limit plate can be sealed by the limit slide grooves at both ends of the limit plate. The sealing component can be set to seal the limiting slide groove to prevent dust and other impurities from entering the fixed seat through the limiting slide groove. In actual use, a corresponding driving component is set inside the moving head on the front side of the traditional electric sliding door. During operation, this part of the driving component will drive the head to move horizontally on the ground, and then drive the door frame on the rear side to move telescopically during the movement of the head. In this process, the head is easily affected by the outside of the head casing and external objects due to insufficient speed of stopping. There is no corresponding protective mechanism on the outside of the head, which can easily cause the impact force to be directly transmitted through the casing to its interior, causing damage to the electrical components inside the head casing and affecting the control of the head movement. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide an inductive correction mechanism for the head of a trackless sliding door, so as to solve the problem that the door frame at the rear side is driven to move telescopically during the current translation of the head. In this process, the head is easily moved electrically, and the outside of the head casing may come into contact and impact with external objects due to insufficient speed for stopping the movement. The outside of the head does not have a corresponding protective mechanism, and the impact force may be directly transmitted through the casing to the inside, causing damage to the electrical components inside the head casing and affecting the technical problem of controlling the movement of the head.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: designing a trackless sliding door head inductive correction mechanism, including a head housing, a telescopic frame fixedly installed on the side of the head housing, and moving wheels installed on both sides of the bottom of the head housing and the telescopic frame;

[0006] A transmission baffle is movably mounted on the side of the front housing, and a protective cushion is fixedly bonded to the side surface of the transmission baffle. Buffer mechanisms are vertically mounted on both end surfaces of the outer side of the front housing, and the buffer mechanisms are transmission-connected to the outer side of the transmission baffle.

[0007] Damping mechanisms are transversely installed at both ends of the side of the front housing, and the damping mechanisms are transmission-connected to the outer side of the transmission baffle.

[0009] Preferably, connecting frames are fixedly installed on the outer side of the push sleeve and the side of the transmission baffle, and a push rod is hingedly connected to each other between the sides of each two groups of the connecting frames through a rotating shaft, and the push rod is movably installed on the outer side of the front housing.

[0010] Preferably, the damping mechanism includes a damping washer and a second buffer spring, and a hollow frame is fixedly installed at both ends of the side of the front housing, and an extrusion plate is slidably installed on the side of each hollow frame close to the transmission baffle, and a damping washer is fixedly sleeved on the outer surface of each extrusion plate, and the damping washer is slidably installed inside the hollow frame, and a push rod is fixedly installed on the side of each extrusion plate, and the push rod is slidably inserted into the inside of the side of the hollow frame, and a fixed sleeve is fixedly sleeved on the outside of the end of each push rod away from the hollow frame, and the outside of the fixed sleeve is fixedly connected to the outside of the transmission plate, and a second buffer spring is movably sleeved inside each hollow frame, and the side of the second buffer spring is movably fitted to the outside of the extrusion plate, and a sliding groove is opened inside the middle end of the side of each hollow frame, and the push rod is slidably inserted into the inside of the sliding groove.

[0012] Preferably, an electromagnetic sensor is fixedly mounted on the bottom of the vehicle front housing, a controller is fixedly mounted on the top of the vehicle front housing, and a signal output end of the electromagnetic sensor is electrically connected to a signal input end of the controller.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a transmission baffle on the side of the front housing, and the side of the transmission rod and the side wall of the transmission baffle are rotatably hinged by a rotating shaft, and the other side of the transmission rod is rotatably hinged to the outer wall of the pushing sleeve which is slidably sleeved on the outer side of the vertically arranged guide rod. When the side of the front housing contacts an obstacle during movement, when the obstacle impacts the outer wall of the front housing, it will impact the transmission baffle in advance and cause it to move leftward toward the outer side of the front housing.

Then, when the pushing sleeve moves vertically on the outside of the guide rod, the buffer spring sleeved on the surface of the guide rod will be squeezed and deformed, thereby buffering the impact force borne by the surface of the transmission baffle, avoiding the impact force directly acting on the side wall of the front casing and causing damage to the front casing, thereby improving the protection of the front casing and its internal drive components.

[0015] 2. The utility model provides a hollow frame on the front and rear sides of the vehicle head casing, and connects the pushing rod connected to the transmission baffle and the extrusion plate inside the hollow frame, so that when the transmission baffle is subjected to external contact impact and moves toward the vehicle head casing, the extrusion plate can be driven by the pushing rod to move horizontally inside the hollow frame synchronously, thereby squeezing the second buffer spring inside the hollow frame to cause it to deform, further buffering the impact force on the surface of the transmission baffle, and combining the contact friction between the damping washer sleeved on the outside of the extrusion plate and the inner wall of the hollow frame, the position recovery speed of the extrusion plate and the transmission baffle can be damped and slowed down, thereby preventing the transmission baffle from moving too fast under the recovery push of the first buffer spring and the second buffer spring and causing a secondary contact collision with external obstacles, thereby further improving the protection of the vehicle head casing.

[0024] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0025] Example 1: Inductive deviation correction mechanism for trackless sliding door head, see Figures 1 to 4 A telescopic frame 11 is fixedly installed on the side of the front casing 1, and moving wheels 12 are installed on both sides of the bottom of the front casing 1 and the telescopic frame 11. A transmission baffle 23 is movably installed on the side of the front casing 1, and a protective cushion 26 is fixedly bonded to the side surface of the transmission baffle 23. Buffering mechanisms are vertically installed on the surfaces of both ends of the outer side of the front casing 1, and the buffering mechanism is connected to the outer side of the transmission baffle 23 by transmission. Damping mechanisms are horizontally installed on both ends of the side of the front casing 1, and the damping mechanism is connected to the outer side of the transmission baffle 23 by transmission. Through the buffering protection of the buffer mechanism and the damping mechanism, the impact force can be buffered after the surface of the transmission baffle 23 is subjected to contact impact, so as to avoid the impact force directly acting on the side wall of the front casing 1 and causing damage to the front casing 1, thereby improving the protection of the front casing 1 and its internal drive components.

[0026] For details, see Figures 1 to 4The buffer mechanism includes a first buffer spring 27 and a transmission rod 25. The mounting plates 2 are fixedly installed on the two end surfaces of the side of the front housing 1, and the number of mounting plates 2 is four. A guide rod 21 is vertically fixedly installed between the sides of each two groups of mounting plates 2. A push sleeve 22 is slidably sleeved on the outer end surfaces of each guide rod 21. A first buffer spring 27 is slidably sleeved on the outer side surface of the middle end of each guide rod 21, and the two ends of the side of the first buffer spring 27 are movably fitted to the outer side of the push sleeve 22. Under the structural action of the first buffer spring 27, the push sleeve 22 moving vertically on the surface of the guide rod 21 can be buffered, thereby realizing the buffering protection treatment of the transmission baffle 23.

[0027] For further information, see Figures 1 to 4 The outer side of the push sleeve 22 and the side of the transmission baffle 23 are fixedly installed with a connecting frame 24, and the sides of each two sets of connecting frames 24 are hinged with a push rod 32 through a rotating shaft, and the push rod 32 is movably installed on the outer side of the front housing 1. Through the transmission conversion action of the push rod 32, the horizontal movement force of the transmission baffle 23 and the vertical movement force of the push sleeve 22 can be converted into each other, thereby ensuring that the impact force can act on the push sleeve 22 to buffer and protect it.

[0028] It is worth noting that, see Figures 1 to 4 The damping mechanism includes a damping washer 35 and a second buffer spring 36. The hollow frame 3 is fixedly installed at both ends of the side of the front housing 1. An extrusion plate 31 is slidably installed on the side of each hollow frame 3 close to the transmission baffle 23. The outer surface of each extrusion plate 31 is fixedly sleeved with a damping washer 35, and the damping washer 35 is slidably installed inside the hollow frame 3. A push rod 32 is fixedly installed on the side of each extrusion plate 31, and the push rod 32 penetrates and slides into the inside of the side of the hollow frame 3. The outer side of each push rod 32 away from the hollow frame 3 is fixedly sleeved. It is connected to a fixed sleeve 33, and the outer side of the fixed sleeve 33 is fixedly connected to the outer side of the transmission plate. A second buffer spring 36 is movably sleeved inside each hollow frame 3, and the side of the second buffer spring 36 is movably fitted to the outer side of the extrusion plate 31. A sliding groove 34 is opened inside the middle end of the side of each hollow frame 3, and the push rod 32 is slidably inserted into the sliding groove 34. The extrusion plate 31 and the transmission baffle 23 are connected by the push rod 32, and under the buffering protection action of the second buffer spring 36, the buffering protection of the front housing 1 can be further improved.

[0029] It is worth noting that see Figures 1 to 4A guide block 4 is fixedly installed on the surface of both ends of the side of each guide rod 21, and a guide groove 41 is opened at both ends of the inner wall of each pushing sleeve 22, and the guide block 4 is slidably inserted into the inside of the guide groove 41. Through the guiding sliding action of the guide groove 41 on the guide block 4, when the pushing sleeve 22 is pushed by the transmission rod 25, the pushing sleeve 22 can only move vertically on the outside of the guide rod 21 without tilting and moving laterally, thereby ensuring the transmission rationality of the overall mechanism.

[0030] It is worth mentioning that see Figures 1 to 4 An inductive sensor is fixedly installed at the bottom of the front housing 1, and a controller 14 is fixedly installed on the top of the front housing 1, and the signal output end of the inductive sensor and the signal input end of the controller 14 are electrically connected. The offset of the door body is detected by the inductive sensor, and after the controller 14 processes and calculates the offset, it combines its internal control actuator to make corresponding adjustments to the direction of travel of the front of the vehicle, thereby completing the correction processing of the direction of travel of the front housing 1.

[0031] During operation, after starting the driving component inside the vehicle head casing 1, the displacement of the vehicle head casing 1 is detected in combination with the inductive sensor located at the bottom of the vehicle head casing 1, and then the detected displacement is transmitted to the inside of the controller 14. The controller 14 receives the signal of the inductive sensor, calculates the deviation correction amount that needs to be adjusted after processing, and controls the actuator to adjust the direction of travel of the vehicle head casing 1 accordingly, thereby completing the deviation correction process of the direction of travel of the vehicle head casing 1. When the vehicle head casing 1 is moving to the right, it comes into contact with an obstacle on its right side. After the collision, the obstacle impacts the surface of the transmission baffle 23 on the side of the vehicle head housing 1, causing the transmission baffle 23 to move synchronously toward the outside of the vehicle head housing 1 and to the left. Under the transmission conversion action of the transmission rod 25, the horizontal movement force of the transmission baffle 23 can be converted into a vertical driving force for the pushing sleeve 22. Combined with the guiding sliding action of the guide rod 21 on the pushing sleeve 22, and the guiding sliding action of the guide slot 41 on the guide block 4, the pushing sleeve 22 sleeved on both sides of the guide rod 21 can be moved left and right along with the transmission baffle 23. The first and second buffer springs 27 and 36 are combined to form a spring which is pressed against the guide bar 21 and is pressed against the guide bar 21. The impact force is buffered to prevent the impact force from directly acting on the left side of the front housing 1 and causing damage to itself and the internal drive components. After the contact impact ends, combined with the contact friction between the damping washer 35 sleeved on the outside of the extrusion plate 31 and the inner wall of the hollow frame 3, the position recovery speed of the extrusion plate 31 and the transmission baffle 23 can be damped and slowed down to prevent the transmission baffle 23 from moving too fast under the recovery push of the first buffer spring 27 and the second buffer spring 36 and causing a secondary contact collision with external obstacles.

[0032] In addition, the components designed in this utility model are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. They can be fully implemented by technical personnel in this field. Needless to say, the content protected by this utility model does not involve improvements to internal structures and methods.

[0033] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
