Description

Technical Field

[0001] This invention belongs to the field of vehicle technology, specifically relating to an improved automotive center console slide rail. Background Technology

[0002] The aforementioned car center console, also known as the car's center console box, is typically located between the driver and front passenger seats. Its function has far exceeded basic storage (such as a storage compartment for small items or CDs) and has become a highly integrated control and comfort hub, or even the central nervous system, of the cockpit. Traditional fixed center consoles (especially in models with traditional gear levers or large armrests) usually form a physical partition, dividing the cockpit into two independent left and right sections. This not only makes the interior space appear cramped but also hinders physical interaction and the passing of items between front and rear passengers to some extent. The fixed location results in a rigid layout that cannot be adjusted according to needs; its functionality is limited—for example, in intelligent cockpits, fixed center screens are usually angled towards the driver for ease of operation. This makes it very difficult for the front passenger to view the screen or interact with entertainment (due to an angled view or excessive distance); the design and technological feel are relatively weak, and the lack of dynamic change makes the interior layout appear static and traditional. However, a movable or sliding center console can break the aforementioned deadlock of a fixed one, achieving spatial openness and dynamic allocation of functions. Specifically, a sliding movable center console upgrades it into a dynamic and intelligent space adjuster. Its essence is that it changes the situation from people adapting to the car to the car adapting to people, breaking the traditional pattern of fixed interior space and rigid functional areas, and giving the interior space a high degree of flexibility. Within the limited physical cabin, through mechanical and intelligent movement, it maximizes the satisfaction of the personalized comfort needs, scenario-based functional needs, and safety and convenience needs of drivers and passengers, etc.

[0003] Publicly available Chinese patent documents contain technical information that enables the center console to move as needed. For example, CN211107049U recommends "a movable center console aluminum alloy electric slide rail", CN215398181U describes "a sliding device for a sub-instrument panel" and CN114992238A provides "a sub-instrument panel slide rail structure and vehicle", etc.

[0004] As is known in the industry, a drive mechanism is undoubtedly required in a sliding rail structure system that serves the center console. The drive mechanism includes a motor, a transmission box, and a lead screw. The motor is mounted on the upper slide rail and drives the transmission box, while the transmission box engages with the lead screw located in the lower slide rail cavity. Since the center console is mounted on the upper slide rail, when the motor operates, it drives the transmission box to move forward or backward along the lead screw (depending on the motor's direction of rotation), thereby causing the upper slide rail, along with the motor and the center console, to move accordingly.

[0005] In existing technologies, perhaps influenced by traditional design thinking, brushless motors are commonly used for the aforementioned drive mechanism structures, even though they outperform brushed motors in terms of efficiency, power density, lifespan, noise, and electromagnetic interference resistance. However, brushless motors require rare-earth magnets (such as neodymium iron boron), which are far more expensive than the ferrite magnets used in brushed motors. Furthermore, brushless motors must be equipped with an electronic commutator, typically including an MCU, driver chip, and MOSFETs, significantly increasing hardware costs. Brushed motors, on the other hand, only require two wires connected to the positive and negative terminals of the power supply, resulting in almost zero cost. In addition, the automotive industry has become extremely sensitive to parts prices in recent years; saving a few to tens of yuan on a single component can translate into substantial profits for large-scale automakers.

[0006] In particular, considering sufficient performance and reliability requirements, the driving needs of automotive center console sliding rails are typically low-power, intermittent, and require low speed precision. Even with an efficiency of only about 60-70%, the absolute power consumption of a brushed motor is only a few watts, which is negligible in terms of overall vehicle energy consumption. From a lifespan perspective, it typically operates for thousands of cycles, far exceeding the designed service life of the vehicle. In other words, the lifespan of a brushed motor is already over-designed for the overall vehicle lifespan. Furthermore, troubleshooting and repairing brushless motor systems is far more complex than visually troubleshooting common brushed motor faults such as brush wear or jamming. Brushed motors are compact and small in size, while brushless motors, including the controller, are much larger. Given the extremely limited space inside the center console, simpler and smaller mechanical structures are often preferred.

[0007] Based on the aforementioned objective factors, and given that the design, production, quality control, and failure modes are now quite mature and have been fully mastered, there are no shortcomings in applying brushed motors to the drive mechanism of automotive center console slide rails. Using brushless motors, on the contrary, would be a blind approach and a waste of resources.

[0008] On the other hand, because the sliding rails of automotive center consoles have relatively stringent requirements for smooth sliding, if the lower rails of the structural system lack adequate protection against dust and debris, a series of negative consequences will occur when foreign objects such as dust, sand, food scraps, and liquids intrude. These consequences include impaired sliding function, wear and permanent damage, blockage and jamming, abnormal noise, positioning failure, increased motor load (potentially burning out the motor), corrosion from liquids leading to short circuits in wiring harness connectors and / or control modules, and increased maintenance costs. Therefore, exploring effective dust protection measures for the lower rails is of significant importance. Furthermore, since the center console integrates numerous functional components that require power, and these components are the core of vehicle electronics and intelligence, wiring management is an indispensable and crucial factor in the structure of automotive center console sliding rails. Summary of the Invention

[0033] The applicant should note that since the sliding range of the center console (not shown in the figure) is limited, the length of the aforementioned upper slide rail 2 is significantly shorter than the length of the lower slide rail 1. The exact length difference depends on the actual application requirements. Different vehicles and different sizes of center consoles require upper slide rails 2 with correspondingly varying lengths to accommodate them. Therefore, in this invention, there is no need to specifically limit the length ratio of the upper slide rail 2 to the lower slide rail 1.

[0034] In this embodiment, the technical term "constraint," as used in the wiring harness constraint mechanism mentioned above, essentially means "control" or "regulation," i.e., preventing tangling (the same applies below). This is because the wiring harness contains power lines (such as cigarette lighter / USB), data interface (USB) lines, controller lines, etc., which need to be connected to the vehicle's power supply and communication network. When the central control box moves, these wiring harnesses must extend and retract in a serpentine manner. Without effective constraint, problems such as swaying, abnormal noises, friction with surrounding parts, wear and short circuits, getting caught in the slide rails causing jamming or breakage, tangling, and affecting aesthetics and reliability may occur.

[0035] Depend on Figure 1 and Figure 2 As shown, a pair of front fixing holes 29a for the center console are provided at the front left and right ends of the aforementioned upper slide rail 2 along its length, and a pair of rear fixing holes 29b for the center console are provided at the rear left and right ends of the upper slide rail 2 along its length.

[0040] By operating the corresponding button on the controller located on the central control panel, the motor 41 is energized, putting it into operation. The motor shaft 411 drives the transmission box 42. Since the transmission box 42 and the lead screw 3 form a transmission pair, the transmission box 42 moves along the lead screw 3. The left or right movement of the transmission box 42 depends on the forward or reverse rotation of the motor 41, which is determined by the corresponding button on the electrical controller on the central control panel. During this process, the upper slide rail 2 can move the central control panel fixed on it accordingly.

[0041] Depend on Figure 1 and Figure 3 As shown, a T-shaped adjustable chain bridge fitting protrusion 1131 is formed along the length of the aforementioned sliding rail cavity partition wall 113 and on the side facing the aforementioned wire harness constraint mechanism cavity 112. Figure 1As shown, the aforementioned wire harness restraint mechanism 5 includes an adjustable chain bridge 51 and a tank chain 52. The adjustable chain bridge 51 is disposed within the wire harness restraint mechanism cavity 112, and the front side of the adjustable chain bridge 51 in the longitudinal direction forms an adjustable chain bridge mating groove 511 with a cross-sectional shape of T. The adjustable chain bridge mating groove 511 is inserted and engaged with the aforementioned adjustable chain bridge mating protrusion 1131. A wire harness introduction is fixed at the left end of the adjustable chain bridge 51. The tube 512, and the bottom left end of the adjustable chain bridge 51 is fixed to the bottom wall of the wire harness constraint mechanism cavity 112 by an adjustable chain bridge fixing screw 513. The adjustable chain bridge fixing screw 513 is screwed into the wire harness constraint mechanism cavity 112 from the bottom outer side of the lower slide rail 1 and then screwed to the bottom left end of the adjustable chain bridge 51. The end of the tank chain 52 facing the adjustable chain bridge 51 is connected to the adjustable chain bridge 51, and the orientation of the tank chain 52 is located at... One end of a wire harness constraint mechanism cavity guide groove opening and closing mechanism 7 at the rear right end of the aforementioned upper slide rail 2 is connected to the aforementioned wire harness constraint mechanism cavity guide groove opening and closing mechanism 7.

The wire harness inlet tube wall 5122 is fixed to the left end of the adjustable bridge 51 by the inlet tube wall fixing screw 51221. The method of fixing the end of the aforementioned tank chain 52 facing the adjustable bridge 51 to the adjustable bridge 51 is the same as described above. Specifically, a tank chain link fixing plate 521 extends to the left from the rear side of the first tank chain link of the tank chain 52. The tank chain link fixing plate 521 is fixed to the right end of the adjustable bridge 51 by the tank chain link fixing plate screw 5211.

[0043] In this embodiment, the aforementioned adjustable bridge 51 essentially eliminates the unnecessary and redundant portion of the tank chain 52. Without the adjustable bridge 51 and instead consisting entirely of the tank chain 52, the tank chain 52 would risk self-interference and even friction. Of course, if the length of the tank chain 52 is too short to meet process requirements, the adjustable bridge 51 can be moved to the left, and vice versa.

Therefore, it can be seen that, except for the structure of the wire harness constraint mechanism cavity guide groove opening and closing mechanism 7 at the rear right end of the upper slide rail 2, which differs from the left end wire harness constraint mechanism cavity guide groove opening and closing mechanism 7 due to the need for connection to the tank chain 52, the left end wire harness constraint mechanism cavity guide groove opening and closing mechanism 7 is the same as the structure of the pair of lead screw cavity guide groove opening and closing mechanisms 6. The aforementioned upper slide rail front Z-direction backlash elimination mechanism 9 is connected to the aforementioned front zipper head seat connecting arm 611 at the position corresponding to the aforementioned front backlash elimination roller shaft threaded hole 6111.

A pair of tank chain hinge plates 713 extend horizontally in a horizontally aligned manner. Each of these plates has a corresponding tank chain pin hinge hole 7131. One end of the opening / closing mechanism 7 of the wire harness constraint mechanism cavity guide groove of the aforementioned tank chain 52, facing the rear right end of the aforementioned upper slide rail 2, is connected to the aforementioned pair of tank chain hinge plates 713 by a tank chain link hinge shaft at a position corresponding to the tank chain pin hinge hole 7131. A rear zipper head T-shaped seat 721 extends from the top of the rear zipper head 72 towards the rear zipper head T-shaped seat support platform 712. This rear zipper head T-shaped seat 721 is supported on the rear zipper head T-shaped seat support platform 712 and is connected to the aforementioned pair of rear zipper head T-shaped seat guide groove ... The zipper tab 402 engages to open or close the aforementioned rear zipper tab opening and closing teeth 4021. The rear zipper head cover connecting seat 73 is inserted into the rear zipper head cover fixing cavity 261 at one end, and is fixed by the zipper head cover rear connecting seat fixing screw 731 to the zipper head cover rear fixing cavity screw hole 2611 on the bottom wall of the zipper head cover rear fixing cavity 261. A rear zipper head cover connecting seat hinge joint 732 extends from one end of the rear zipper head cover connecting seat 73 toward the rear zipper head cover 74. A rear zipper head cover connecting seat hinge joint hole 7321 is formed on the rear zipper head cover 732. A pair of upwardly protruding rear zipper head covers are formed on the top surface of the rear zipper head cover 74 at one end toward the rear zipper head cover connecting seat hinge joint 732. The rear zipper head cover hinge 741 has a hinge ear hole 7411 at a corresponding position on each of the pair of rear zipper head cover hinge ears 741. The aforementioned rear zipper head connecting seat hinge joint 732 extends between the pair of rear zipper head cover hinge ears 741, and the aforementioned rear zipper head connecting seat hinge joint hole 7321 corresponds to the rear zipper head cover hinge ear hole 7411. The rear zipper head connecting seat hinge joint 7322 is hinged to the pair of rear zipper head cover hinge ears 741 at positions corresponding to the rear zipper head cover hinge ear hole 7411 and the rear zipper head connecting seat hinge joint hole 7321, and locked by a locking nut 73221. The space at the lower part of the rear zipper head cover 74 constitutes the rear zipper head protection cavity 742.On the top wall of the rear zipper head cover cavity 742, at a position corresponding to the rear zipper head T-shaped seat 721, a pair of rear zipper head T-shaped seat positioning blocks 7421 are formed. The space between the pair of rear zipper head T-shaped seat positioning blocks 7421 forms a rear zipper head T-shaped seat embedding cavity 74211, and the rear zipper head T-shaped seat 721 is fitted into the rear zipper head T-shaped seat embedding cavity 74211. The aforementioned upper slide rail rear Z-direction backlash elimination mechanism 20 is connected to the aforementioned rear zipper head seat connecting arm 711 at a position corresponding to the aforementioned rear backlash elimination roller shaft threaded hole 7111. A tank chain hinge cavity 714 for hinged to the end of a tank chain link unit of the tank chain 52 is formed on the aforementioned rear zipper head seat 71 at a position corresponding to the pair of tank chain hinge plates 713. The tank chain hinge cavity 714 communicates with the rear zipper head seat wire harness lead-out cavity 715 formed on the rear zipper head seat 71.

[0051] In order to facilitate the operation of tools such as screwdrivers on the aforementioned zipper head cover rear connecting seat fixing screw 731, a screwdriver insertion clearance hole 262 is provided on the left and right ends of the upper surface of the aforementioned center console rear support fixing seat 26, and at the position corresponding to the zipper head cover rear connecting seat fixing screw 731.

[0052] Based on the above description of the lead screw cavity guide groove opening and closing mechanism 6 and the wire harness constraint mechanism cavity guide groove opening and closing mechanism 7, and in conjunction with... Figure 5 and Figure 6 As can be seen from the diagram, the wire harness constraint mechanism cavity guide groove opening and closing mechanism 7 located at the right end of the upper slide rail 2 has an additional pair of tank chain hinge plates 713, tank chain pin hinge holes 7131, tank chain hinge cavity 714, and rear zipper head seat wire harness lead-out cavity 715 compared to the wire harness constraint mechanism cavity guide groove opening and closing mechanism 7 at the left end of the upper slide rail 2. The rest are the same as the lead screw cavity guide groove opening and closing mechanism 6.

[0053] Please see Figure 4Since the connection method between the aforementioned upper slide rail rear Z-axis backlash elimination mechanism 20 and the aforementioned rear zipper head seat connecting arm 711 is the same as the connection method between the aforementioned upper slide rail front Z-axis backlash elimination mechanism 9 and the aforementioned front zipper head seat connecting arm 611, the applicant will only describe the upper slide rail front Z-axis backlash elimination mechanism 9 in detail below. The aforementioned upper slide rail front Z-axis backlash elimination mechanism 9 includes a front Z-axis backlash elimination roller swing arm 91, a Z-axis backlash elimination roller 92, a support roller 93, and a backlash elimination pad 94. The front Z-axis backlash elimination roller swing arm 91 is located on the front side of the aforementioned Z-axis backlash elimination mechanism front pivot support 24, and a front Z-axis backlash elimination roller swing arm bend 911 is formed at the end of the front Z-axis backlash elimination roller swing arm 91 facing the aforementioned front pad mounting groove 25a. The front Z-axis backlash elimination roller swing arm bend 911 extends into the aforementioned front pad mounting groove 25a. A support wheel shaft hole 912 is provided at one end of the Z-axis backlash elimination roller swing arm 91 facing the lead screw cavity guide groove opening and closing mechanism 6. This support wheel shaft hole 912 corresponds to the Z-axis backlash elimination mechanism front pivot support seat hole 241 provided on the Z-axis backlash elimination mechanism front pivot support seat 24, and communicates with the aforementioned zipper head seat front mating cavity 221 via the Z-axis backlash elimination mechanism front pivot support seat hole 241. The Z-axis backlash elimination roller 92 is rotatably mounted in the middle of the front Z-axis backlash elimination roller swing arm 91 via the Z-axis backlash elimination roller shaft 921. The Z-axis backlash-eliminating roller 92 and the top wall of the lead screw cavity 111 form a rolling pair. The support roller 93 is equipped with a support roller bearing 931. The support roller bearing 931 and the support roller 93 are fixed on the front Z-axis backlash-eliminating roller swing arm 91 by the support roller bearing pin screw 9311. The support roller 93 and the bottom wall of the lead screw cavity 111 form a rolling pair for eliminating X-axis backlash. The support roller bearing pin screw 9311 is screwed into the aforementioned support wheel shaft hole 912. The threaded hole 6111 of the front backlash elimination roller shaft connects the front Z-axis backlash elimination mechanism 9 of the upper slide rail to the opening and closing mechanism 6 of the lead screw cavity guide groove. The backlash elimination pad 94 is located below the end of the aforementioned front Z-axis backlash elimination roller swing arm 91 facing the front pad mounting groove 25a. The backlash elimination pad 94 is U-shaped with the top wall of the U-shape facing upward. It is made of rubber or other similar materials and is embedded in the front pad mounting groove 25a. The aforementioned bent portion 911 of the front Z-axis backlash elimination roller swing arm abuts against the upper surface of the backlash elimination pad 94. Like a lever, the elasticity of the backlash elimination pad 94 lifts the bent portion 911 of the front Z-axis backlash elimination roller swing arm upward, so that the Z-axis backlash elimination roller 92 can reliably form a rolling pair with the top wall of the lead screw cavity 111. At the same time, the support roller 93 plays an ideal role in eliminating X-axis backlash.

[0054] Because unavoidable fluctuations will occur between the pair of front zipper pieces 302 and their opening and closing teeth 3021 in the aforementioned structural system of the front zipper head 62 and the front guide groove zipper piece assembly 30, these fluctuations are due to positional fluctuations (such as slight changes in height or slight lateral offsets) that may occur during the movement of the pair of front zipper pieces 302 on the upper slide rail 2 due to material flexibility, installation tolerances, or stress deformation. Since the aforementioned support roller bearing pin screw 9311 is connected to the front zipper head seat 61 at the position corresponding to the aforementioned front backlash-eliminating roller shaft threaded hole 6111, the fluctuations can ultimately be eliminated by the Z-direction backlash-eliminating roller 92 on the front Z-direction backlash-eliminating roller swing arm 91 and the support roller 93 that performs X-direction backlash elimination. Of course, the aforementioned fluctuation factors cannot exclude those originating from manufacturing and assembly tolerances, dynamic changes and vibrations during vehicle operation, wear during use, etc. In summary, this invention compensates for the aforementioned fluctuations by connecting the supporting roller bearing pin screw 9311 of the upper slide rail front Z-axis backlash elimination mechanism 9 to the front zipper head seat 61 of the lead screw cavity guide groove opening and closing mechanism 6. Simultaneously, it absorbs tolerances and adapts to dynamic changes, ensuring smooth and reliable opening and closing of the front zipper teeth 3021, embodying the "floating compensation" principle in mechanical structure design. This satisfies the requirement of flexible structures adapting to each other within rigid systems.

[0055] As explained above, since the aforementioned support roller 93 essentially functions as an X-direction backlash-eliminating roller, it can be called an X-direction backlash-eliminating roller. Furthermore, because the backlash-eliminating pad 94 is elastic and lifts the bent portion 911 of the front Z-direction backlash-eliminating roller swing arm upwards, it ensures that the Z-direction backlash-eliminating roller 92 and the top wall of the screw cavity 111 form a good rolling pair to eliminate Z-direction backlash. Therefore, this backlash-eliminating pad 94 can also be called a backlash-eliminating roller swing arm bent portion push block.

[0056] Since the structure of the aforementioned pair of upper slide rail rear Y-direction backlash elimination mechanism 10 is the same as the structure of the aforementioned pair of upper slide rail front Y-direction backlash elimination mechanism 8, the applicant will only describe the pair of upper slide rail front Y-direction backlash elimination mechanisms 8 below. Each of the pair of upper slide rail front Y-direction backlash elimination mechanisms 8 includes a Y-direction backlash elimination roller frame 81 and a Y-direction backlash elimination roller 82. The two ends of the Y-direction backlash elimination roller frame 81 are fixed to the aforementioned Y-direction backlash elimination mechanism front fixed seat 22 by roller frame fixing screws 811. The Y-direction backlash elimination roller 82 is rotatably arranged in the middle of the Y-direction backlash elimination roller frame 81 through the Y-direction backlash elimination roller shaft 821, and the Y-direction backlash elimination roller 82 and the front cavity wall of the aforementioned lead screw cavity 111 form a rolling pair, thereby the Y-direction backlash elimination roller 82 plays the role of eliminating the Y-direction backlash of the upper slide rail 2 during the sliding process.

[0057] Please see Figure 7 and Figure 8 And combined Figures 1 to 6 ,exist Figure 7The figure shows the tank chain cavity 522 of the tank chain 52. The wire harness (not shown) is sequentially introduced into the tube cavity 5121 and the adjustable bridge cavity and tank chain cavity of the adjustable bridge 51 through the wire harness, thus forming the tank chain link cavities of the tank chain 52. Figure 6 The tank chain hinge cavity 714, which is formed on the rear zipper head seat 71, enters the rear zipper head seat wiring harness lead-out cavity 715, which is also formed on the rear zipper head seat 71. The wiring harness is led out from the rear zipper head seat wiring harness lead-out cavity 715 to the electrical controller of the center console, which is not shown in the figure and is mounted on the upper slide rail 2. The aforementioned lower slide rail 1 is usually fixed to the vehicle's floor.

[0058] As mentioned above, under the operation of the upper slide rail sliding drive mechanism 4, the motor 41, i.e., the tubular brushed motor, causes the transmission box 42 to move from left to right on the lead screw 3. At this time, the entire upper slide rail sliding drive mechanism 4, together with the upper slide rail 2, also moves from left to right accordingly. During the aforementioned process, the lead screw cavity guide groove opening and closing mechanism 6 and the wire harness constraint mechanism cavity guide groove opening and closing mechanism 7 located at the right end of the upper slide rail 2 simultaneously open each pair of front and rear zipper pieces 302 and 402 of the front and rear guide groove zipper piece assemblies 30 and 40, respectively. That is to say, the front and rear zipper piece opening and closing teeth 3021 and 4021 are opened, so as to facilitate the upper slide rail 2 and the central control panel mounted on it to slide to the right. At the same time, the screw cavity guide groove opening and closing mechanism 6 and the wire harness constraint mechanism cavity guide groove opening and closing mechanism 7 located at the left end of the upper slide rail 2 simultaneously close each pair of front and rear zipper pieces 302 and 402 of the front and rear guide groove zipper piece assemblies 30 and 40, respectively, which means that the opening and closing teeth 3021 and 4021 of the front and rear zipper pieces are closed. The reverse is also true.

[0059] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above-mentioned technical effects column.
