Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. In order to make the technical solution and advantages of the present application more apparent, the following detailed description of the electronic steering column assembly device and the like will be given with reference to the accompanying drawings.

The electronic steering column comprises a steering column lock body and a steering column, when the vehicle is in a non-use state, a lock tongue of the steering column lock body is clamped into the steering column, and a steering wheel is locked and cannot rotate; when the vehicle is in a use state, the lock tongue of the steering column lock is separated from the steering column, and the steering wheel is unlocked and can normally rotate. Thus, the accuracy of the assembly between the steering column lock and the steering column is critical to the proper use of the vehicle.

In the related art, the assembly between the steering column lock and the steering column is mainly performed manually to fix the steering column and to assemble the steering column lock to the steering column.

However, the manual assembly is difficult to ensure the assembly accuracy, and the probability of assembly dislocation is high, so that the normal operation of the steering column is influenced; in addition, the manual assembly cost is high, the assembly efficiency is low, and great personal safety hidden trouble exists.

For solving above-mentioned technical problem, this application provides an electron steering column assembly quality, enables the assembly of tubular column and lock body more accurate, high-efficient, and assembly process is safer, and reduces the cost of labor.

As shown in fig. 1 and 2, the device comprises a first seat 1, a second seat 2, a first positioning assembly 3 and a second positioning assembly 4; the first housing 1 is configured to house a column 110 of an electronic steering column; the second housing 2 is located in the first direction of the first housing 1 and is configured to house a lock 120 of an electronic steering column; at least a portion of the first positioning assembly 3 is located in the second direction of the first seat 1 and is movable relative to the first seat 1 to approach or depart from the first seat 1; the second positioning component 4 is connected with the second seat body 2 and can drive the second seat body 2 to move so as to be close to or far away from the first seat body 1; wherein the first direction and the second direction intersect.

The first direction and the second direction intersect, and the condition that the first direction is the same as or opposite to the second direction is not included.

When the electronic steering column assembly device provided by the embodiment of the application is used for assembling an electronic steering column, the column 110 can be firstly installed in the first seat body 1, and then the first positioning component 3 is moved to be close to the first seat body 1 and is abutted against the column 110; the lock body 120 is installed in the second seat body 2, and the second seat body 2 is driven to move towards the first seat body 1 through the second positioning component 4, so that the lock body 120 moves to a position matched with the pipe column 110, and the positioning of the lock body 120 on the pipe column 110 is realized; after the lock body 120 and the pipe column 110 are positioned, the screw holes on the lock body 120 are opposite to the screw holes on the pipe column 110, and the fastening bolts are screwed into the two screw holes, so that the lock body 120 and the pipe column 110 are connected and fixed.

Thus, in the present embodiment, the electronic steering column assembly device implements the lock body 120 and the column 110 through the cooperation between the first housing 1, the second housing 2, the first positioning assembly 3, and the second positioning assembly 4. Specifically, the first seat 1 can accommodate the column 110 of the electronic steering column, and the second seat 2 is located in the first direction of the first seat 1 and can accommodate the lock 120 of the electronic steering column; the first positioning component 3 can move relative to the first seat body 1, and when the first positioning component 3 moves to be propped against the pipe column 110, the pressure opposite to the second direction can be applied to the pipe column 110 to fix the pipe column 110 in the first seat body 1; the second positioning component 4 is connected with the second base body 2 and can drive the second base body 2 to move, when the second base body 2 moves to enable the lock body 120 to lean against the pipe column 110, the position where the lock body 120 is located is the position where the lock body is matched with the pipe column 110, so that the positioning of the lock body 120 on the pipe column 110 is realized, and the assembly efficiency and the assembly accuracy are improved.

The first seat 1 is configured to accommodate the column 110 of the electronic steering column, that is, the first seat 1 has a first accommodating cavity, and the column 110 of the electronic steering column enters from an opening end of the first accommodating cavity and is accommodated in the first accommodating cavity, so that preliminary positioning and fixing of the column 110 by the first seat 1 are realized. Similarly, the second seat 2 is configured to accommodate the lock body 120 of the electronic steering column, that is, the second seat 2 has a second accommodating cavity, and the lock body 120 of the electronic steering column enters from the opening end of the second accommodating cavity and is accommodated in the second accommodating cavity, so that preliminary positioning and fixing of the second seat 2 to the lock body are realized.

In some embodiments, the first receiving cavity is shaped to conform to the shape of the tubular string 110 and the second receiving cavity is shaped to conform to the shape of the lock body 120.

As shown in fig. 2, the column 110 of the electronic steering column is an irregularly shaped structure with a certain length and weight, and in order to avoid assembly errors caused by movement of the column during assembly with the lock body 120, a first positioning component 3 is disposed in the second direction of the first seat 1, and the first positioning component 3 can be close to the first seat and abut against the column 110, so that the column can be relatively firmly fixed in the first seat 1.

Alternatively, the second direction may be an opening direction of the first accommodation chamber. For example, in fig. 1, the first accommodating chamber is opened upward, and a part of the first positioning member 3 is located above the first housing 1.

Optionally, the second direction is perpendicular to the first direction. For example, the first direction is a horizontal direction and the second direction is a vertical direction.

In the embodiment of the present application, the movement forms of the first positioning component 3 and the second positioning component 4 may be the same or different. Alternatively, at least a portion of the first positioning component 3 may rotate relative to the first base 1, and the second positioning component 4 may drive the second base 2 to translate relative to the first base 1, in which case the track of the portion of the first positioning component 3 located in the second direction of the first base 1 near or far from the first base 1 comprises an arc track, and the track of the second base 2 near or far from the first base 1 comprises at least one straight track.

In some embodiments, as shown in fig. 1, the first positioning assembly 3 includes a first transmission member 31 and a first driving member 32; the first driving part 32 is hinged with the first transmission part 31 and can drive the first transmission part 31 to rotate around the hinged part; and/or the second positioning assembly 4 comprises a second transmission member 41 and a second driving member 42; one end of the second transmission member 41 is connected to the second housing 2, and the other end is connected to the second driving member 42; the second driving part 42 is for applying a driving force parallel to the first direction to the second transmission part 41 under control.

As shown in fig. 1, an end of the first transmission member 31 remote from the first driving member 32 may be located in the second direction of the first housing 1, and when the first transmission member 31 rotates around the hinge, the end of the first transmission member 31 remote from the first driving member 32 approaches or moves away from the pipe string 110 installed in the first housing 1 as it rotates.

The second transmission part 41 is located in the first direction of the second seat body 2 and is fixedly connected with the second seat body 2, and the second driving part 42 can apply driving force to the second transmission part 41, wherein when the direction of the driving force is the first direction, the second transmission part 41 drives the second seat body 2 to be far away from the first seat body 1; when the direction of the driving force is opposite to the first direction, the second transmission part 41 drives the second seat 2 to approach the first seat 1.

In order to make the technical solutions and advantages of the present application more clear, the first transmission member 31, the first driving member 32, the second transmission member 41, and the second driving member 42 provided in the embodiments of the present application are described and illustrated in detail below with reference to fig. 3 to 6.

In some embodiments of the present application, as shown in fig. 3, the first driving part 32 may include a first support 321 and a first pull rod piece 322, the first support 321 being hinged with the first transmission part 31, and the first pull rod piece 322 being fixedly connected with the first transmission part 31, for example, by a fastening member such as a bolt.

The first support 321 is used for mounting and fixing the first driving part 32, and the first pull rod piece 322 is used for receiving external actuation. In this embodiment, the assembler can pull or push the first pull rod piece 322, so that the first pull rod piece 322 directly drives the first transmission component 31 to rotate around the hinge position of the first transmission component 31, and the first transmission component 31 is close to or far from the first seat body 1.

In other embodiments of the present application, as shown in fig. 4, the first driving part 32 includes a first support 321 and a first pull rod piece 322; the first supporting piece 321 is hinged with the first pull rod piece 322 and the first transmission part 31 respectively; the first rod piece 322 is connected with the first transmission part 31 and drives the first transmission part 31 to rotate around a first hinge point 3211, wherein the first hinge point 3211 is a hinge point between the first supporting piece 321 and the first transmission part 31.

In this embodiment, the assembler can pull or push the first pull rod piece 322 to rotate the first pull rod piece 322 around the hinge position of the first pull rod piece and the first support piece 321, and since the first pull rod piece 322 is also connected with the first transmission component 31, the first pull rod piece 322 simultaneously drives the first transmission component 31 to rotate around the hinge position of the first transmission component 31 and the first support piece 321, so that the first transmission component 31 is close to or far away from the first seat body 1.

The first pull rod piece 322 and the first transmission component 31 may be movably connected, or may be fixedly connected, so long as the first transmission component 31 can move along with the first pull rod piece 322, thereby changing the distance between the first pull rod piece and the first seat body 1.

In some embodiments, as shown in fig. 4 and fig. 5, the first supporting piece 321 includes a first connecting shaft 3212, a second connecting shaft 3213, and two supporting plates 3214, where the two supporting plates 3214 are opposite and spaced apart, and each supporting plate 321 is provided with a first through hole 3215 and a second through hole 3216; the first transmission member 31 is located between the two support plates 3214, the first transmission member 31 has a third through hole 3111, and the first connection shaft 3212 passes through the first through hole 3215 and the third through hole 3111; the first pull rod piece 322 includes two connection plates 3221, the two connection plates 3221 are respectively located at one side of the two support plates 3214 far away from the first transmission component 31, a fourth through hole 3222 is formed in each connection plate 3221, and the second connection shaft 3213 passes through the second through hole 3216 and the fourth through hole 3222; the first link 322 may be hinged with the second connecting shaft 3213.

As shown in fig. 4, an accommodating space is formed between the two support plates 3214 of the first support 321, and a portion of the first transmission member 31 extends into the accommodating space and is coupled to the two support plates 3214 by a first coupling shaft 3212. The first connecting shaft 3212, the first transmission member 31 and the support plate 3214 are in a shaft hole negative fit, and the diameter of the first connecting shaft 3212 is slightly smaller than the diameters of the first through hole 3215 and the third through hole 3111, so that the first transmission member 31 can rotate relative to the two support plates 3214. The inner walls of the two support plates 3214 can play a certain guiding role on the rotation direction of the first transmission part 31, so as to avoid the first transmission part 31 from being skewed in the rotation process, and the inner walls of the two support plates 3214 refer to opposite and mutually close plate walls on the two support plates 3214.

The two connecting plates 3221 of the first pull rod piece 322 are respectively located at one side of the two support plates 3214 away from each other, so that the accommodating space is not occupied, and the influence on the rotation of the first transmission part 31 in the accommodating space is avoided. The two connection plates 3221 are respectively connected with the two support plates 3214 in a matching way through the second connection shaft 3213, and shaft holes are also adopted for negative matching among the second connection shaft 3213, the connection plates 3221 and the support plates 3214, and the diameter of the second connection shaft 3213 is slightly smaller than that of the second through hole 3216 and the fourth through hole 3222, so that each connection plate 3221 can rotate relative to the support plate 3214 connected with the connection plate. The outer walls of the two support plates 3214 can play a certain guiding role on the rotation direction of the connecting piece, so that the connecting plate 3221 is prevented from being skewed in the rotation process, and the outer walls of the two support plates 3214 refer to opposite and mutually far-away plate walls on the two support plates 3214. In the present embodiment, two connection plates 3221 are connected to each other, and the two connection plates 3221 after connection are connected to the first transmission member 31 as a whole; alternatively, both connecting plates 3221 are connected to the first transmission member 31. In some embodiments, as shown in fig. 4 and 5, the first driving part 32 further includes a first connection member 323, a first end of the first connection member 323 is connected to the first pull rod member 322, and a second end is connected to the first transmission part 31, and a second end and a first end of the first connection member 323 are opposite. The first pull rod piece 322 drives the first transmission part 31 to rotate through the first connecting piece 323, wherein the first connecting piece 323 and the first pull rod piece 322 and the first connecting piece 323 and the first transmission part 31 can be movably connected or fixedly connected.

In some embodiments, as shown in fig. 4, the first connector 323 is located between two connection plates 3221; the first pull rod piece 322 further comprises a third connecting shaft 3223, and each connecting plate 3221 is further provided with a fifth through hole 3224; a sixth through hole 3231 is opened at a first end of the first link 323, and the third link shaft 3223 passes through the fifth through hole 3224 and the sixth through hole 3231, and the second end of the first link 323 is clamped between the first pull rod piece 322 and the first transmission member 31.

The third connecting shaft 3223, the connecting plate 3221 and the first end of the first connecting piece 323 adopt shaft hole matching, and the specific matching mode can be negative matching, positive matching or interference matching. The connection plate 3221 can drive the first connection member 323 to move through the third connection shaft 3223.

The second end of the first connecting piece is positioned between the first pull rod piece and the first transmission part and is clamped by the connecting piece of the first pull rod piece and the first transmission part. The term "clamping" refers to a large interaction force on the contact surface of the first connecting piece and the connecting plate, and on the contact surface of the first connecting piece and the first transmission part. When the first pull rod piece rotates under the action of external force, the first connecting piece is not easy to move relative to the connecting plate due to the fact that larger static friction force exists on the two contact surfaces, and the first transmission part is not easy to move relative to the first connecting piece, so that the first connecting piece and the first transmission part both follow the first pull rod piece to move.

In this embodiment, as shown in fig. 4, the axes of the first connecting shaft, the second connecting shaft, and the third connecting shaft are parallel to each other and do not overlap with each other.

In some embodiments, as shown in fig. 5, the first connector 323 is positioned in a second direction of the support plate 3214; the surface 32141 of the support plate 3214 facing the first link 323 has a curved surface portion, the first link 323 is located on a concave side of the curved surface portion, and the second end of the first link 323 is in contact with and slidable on the surface 32141 of the support plate 3214.

The shape of the curved surface part is matched with the moving track of the first connecting piece. When the first link member 322 rotates about the second link shaft 3213 to move the first transmission member 31 away from the first housing 1, the second end of the first link 323 slides from the middle position of the curved portion of the surface 32141 of the support plate 3214 toward the edge of the curved portion and is separated from the first surface 32141 from the edge of the curved portion. When the first link member 322 rotates about the second link shaft 3213 to bring the first transmission member 31 close to the first housing 1, the second end of the first link 323 slides in from the edge of the curved portion of the surface 32141 of the support plate 3214 and toward the middle of the curved portion.

In the present embodiment, the maximum moving distance of the first transmission member 31 in the opposite direction to the second direction can be limited by the engagement between the first link 323 and the curved surface portion. As shown in fig. 5, the first link 323 is located at the concave side of the curved surface portion, and it will be understood by those skilled in the art that the greater the moving distance of the first transmission member 31 in the second direction under the action of the actuating force, the more the first link 323 slides from the middle position of the curved surface portion to the edge; conversely, the greater the distance of movement of the first transmission member 31 in the opposite direction to the second direction under the action of the actuating force, the more the first link 323 slides from the edge of the curved surface portion toward the intermediate position. When the first connecting member 322 contacts the lowest point of the curved surface portion, it receives a reverse force from the first supporting member 321, so that the first connecting member 323 forms a rigid support between the first pull rod member 322 and the curved surface portion of the first supporting member 321, and thus the first transmission member 31 is locked at the current position and cannot be further moved toward the first seat 1 (or the pipe column 110), that is, cannot be moved in the reverse direction of the second direction. Wherein the lowest point of the curved surface portion refers to a point located at a middle position of the curved surface portion and farthest from an edge of the curved surface portion in the second direction.

In some embodiments, as shown in fig. 5, the first transmission member 31 includes a second connector 311 and a retainer 312; one end of the second connecting piece 311 is hinged with the first driving part 31, and the other end is movably connected or detachably connected with the positioning piece 312; the positioning piece 312 is used for pressing against the pipe column 110 located in the first seat body 1.

The positioning piece 312 is used for pressing against the pipe column located in the first seat body 1, so that the pipe column is not easy to separate from the first seat body 1. In some embodiments, the positioning member 312 is slidably connected to the second connecting member 311, and the second connecting member 311 may have a slide 3112, and the positioning member 312 is connected to the second connecting member and is movable within the slide 3112, and the positioning member 312 may be locked at any position on the slide 3112. Optionally, the extension direction of the slide 3112 is perpendicular to the length direction of the pipe string 110. In other embodiments, the second connecting member 312 has at least two mounting structures thereon, where the at least two mounting structures are disposed at intervals on the second connecting member 311, and the positioning member 312 may be detachably connected to any one of the mounting structures according to the arrangement requirement, for example, by bolting or dismounting. Alternatively, at least two mounting structures are arranged along the length direction of the second connection member 311, and the length direction of the second connection member 311 is perpendicular to the length direction of the pipe string 110.

Optionally, the positioning member 312 is located in the second direction of the pipe string 110 and abuts against the pipe string 110.

In some embodiments, as shown in fig. 6, the second driving part 42 includes a first stopper 421, a second supporter 422, a second pull rod piece 423, and a first hinge piece 424.

Optionally, the first limiting member 421 and the second supporting member 422 are integrally connected.

In some embodiments, as shown in fig. 6, when the second seat 2 is closest to the first seat 1, the second hinge point 4232 is located on a side of the second support 422 closest to the second seat 2.

In the embodiment of the present application, "when the second seat 2 is closest to the first seat 1" refers to when the lock body 120 located in the second seat 2 and the pipe column 110 located in the first seat 1 are located. Since the second hinge point 4232 is located at the side of the second supporting member 422 near the second seat 2, the second hinge point 4232 can move to the side of the second supporting member 422 far away from the second seat 2 along with the rotation of the second pull rod member 423, so that the second pull rod member 423 can drive the second transmission member 41 to have a large enough movable distance in the first direction, thereby meeting the assembly positioning requirements of locks and pipe columns with various models and sizes.

In the embodiment of the present application, when the second hinge point 4232 on the second link member 423 is located on the same line as both ends of the second transmission member 41 in the first direction, it can be considered that the second link member 423 reaches the maximum moving distance in the opposite direction of the first direction at this time. The second driving part 42 further includes a locking member for locking the second link 423 at a position corresponding to the maximum moving distance for a subsequent assembly operation.

However, in some cases, for example, when the size of the lock body 120 is small, if the second pull rod piece 423 is locked at the maximum moving distance, the lock body 120 is far from the pipe string 110, and cannot be accurately positioned on the pipe string 110; or when the size of the lock body 120 is large, if the second link 423 is locked at the maximum moving distance, the distance between the second housing 2 and the first housing 1 is too short, and the lock body 120 cannot be installed in the second housing 2.

Thus, in some embodiments, as shown in fig. 6, the second transmission member 41 includes a third connection 411 and a first screw 412; the third connecting member 411 has an internal thread; at least a portion of the first screw 412 has an external thread, one end of the first screw 412 is located inside the third connecting member 411 and is in threaded connection with the third connecting member 411, and the other end of the first screw 412 is connected with the second seat 2.

By adjusting the protruding length of the first screw 412 from the third connecting member 411, the distance between the second housing 2 and the first housing 1 can be further adjusted with the second link 423 locked at the maximum moving-in distance.

For example, when the second pull rod piece 423 is locked at the maximum moving distance, but the lock body 120 is still far from the pipe column 110, the first screw 412 may be screwed out from the third connecting piece 411 to further push the second seat 2 to approach the first seat 1 until the second seat 2 is located at a proper position, and the lock body 120 can successfully achieve positioning on the pipe column 110. When the second pull rod piece 423 is locked at the maximum moving distance, but the lock body 120 is too close to the pipe column 110, the first screw 412 can be screwed into the third connecting piece 411, so that the second seat body 2 is far away from the first seat body 1 until the second seat body 2 is located at a proper position, and the lock body 120 can smoothly realize positioning on the pipe column 110. Thus, by adjusting the unscrewing length of the first screw 412 from the third connector 411, a positioning match of different types of lock bodies 120 and columns 110 on the electronic steering column assembly device can be achieved.

In some embodiments, as shown in fig. 6, the electronic steering column assembly device further includes a moving assembly 5, by which the second housing 2 can be moved.

Alternatively, the sliding rail extends parallel to the first direction, and the sliding fitting is connected to the bottom of the second seat 2.

Optionally, the sliding matching piece is a sliding groove, and the track of the sliding rail is positioned in the sliding groove.

In some embodiments, the electronic steering column assembly device further comprises an assembly table 6, and the first seat 1, the second seat 2, the first positioning assembly 3 and the second positioning assembly 4 are respectively fixed on a table top of the assembly table 6. For example, the first housing 1, the second housing 2, the first positioning assembly 3 and the second positioning assembly 4 may be welded to the assembly table 6, respectively, or fixedly connected to the assembly table 6 by bolts, respectively.

Optionally, the first seat 1 includes at least two sub-seats sequentially arranged and spaced along the length direction of the pipe column 110; the table top of the assembly table 6 is provided with a recovery opening 61, the recovery opening 61 is positioned between two adjacent sub-base bodies, a recovery groove 62 is arranged below the table top of the assembly table 6, the recovery groove 62 is opposite to and communicated with the recovery opening 61, and the recovery groove 62 is used for recovering waste falling from the recovery opening 61 during the assembly of the pipe column 110 and the lock body 120.

For anti-theft or securing safety of the vehicle, a break bolt may be selected as a fastening bolt for fixing the lock body 120 of the electronic steering column and the column 110. The screw portion of the broken bolt can be fully screwed into the screw hole communicated with the lock body 120 and the pipe column 110, and after the broken bolt is screwed into the screw hole of the lock body 120 and the pipe column 110, the screw cap of the broken bolt can be screwed off after the lock body 120 and the pipe column 110 are fixedly connected; if the lock body 120 and the pipe column 110 are to be disassembled after the screw cap is broken, special tools or a long time are required for realizing the disassembly, so that the theft prevention of the vehicle can be realized.

The nuts of the broken bolts, which are broken off as scrap, usually need to be collected after assembly in order not to interfere with the subsequent assembly work. But this consumes additional labor costs and reduces assembly efficiency. In this application embodiment, when the fixed lock body 120 of assembly and tubular column 110, owing to be provided with recovery opening 61 on the assembly bench 6 to recovery opening 61 is located the lock body 120 and tubular column 110 cooperation position under, when the nut fracture falls down, just can drop in recovery tank 62 through recovery opening 61, reduced waste recovery cost, improved waste recovery efficiency and assembly efficiency.

When the electronic steering column assembly device provided by the embodiment of the application is used for assembling the lock body 120 and the column 110, the column 110 can be placed in the first seat body 1 first, and then the first pull rod piece 322 is pushed to drive the positioning piece 312 to approach the column 110 from the opening side of the first accommodating cavity until the positioning piece abuts against the column 110, so that the positioning piece 312 is fixed on the first seat body 1, and the abutting surface of the positioning piece 312 and the column 110 is located in the second direction. Then, the lock body 120 is placed in the second housing 2, and the second pull rod piece 423 is pushed to push the second housing 2 to move toward the first housing 1, during which the guide cylinder 4211 limits the moving direction of the second transmission member 41 to be parallel to the first direction, so that the second housing moves in the opposite direction to the first direction, and the slide rail provides a smooth moving track for the second housing 2. After the second link 423 is rotated to a position corresponding to the maximum moving-in distance, the second link 423 is locked. At this time, if the distance between the pipe column 110 and the lock body 120 is not suitable, the distance between the second seat 2 and the first seat 1 can be further adjusted by setting and adjusting the unscrewing distance of the first screw 412 in the third connecting piece 411, so that the pipe column 110 and the lock body 120 can be accurately positioned.

After the positioning of the pipe column 110 and the lock body 110 is completed, a plurality of broken bolts can be screwed into a plurality of pairs of screw holes correspondingly communicated with the pipe column 110 and the lock body 110 by using an electric screwdriver, so that the pipe column 110 and the lock body 110 are fixedly connected.
