A kind of door glass guide's groove, door, car and its manufacturing assembly method

Abstract

The application discloses a glass guide groove of a vehicle door, a vehicle door, a vehicle and a manufacturing and assembling method thereof, and belongs to the technical field of automobile bodies. The glass guide groove comprises a groove body, and a guide block is arranged on the groove body. The guide block is configured to horizontally guide and correct the movement track of the glass before the vehicle window glass is lifted to a closed position. The application is particularly suitable for a vehicle model with a small A-pillar inclination angle and a front door window frame front-rear boundary length ratio (A / B) less than 0.37. The guide block is arranged at a specific position in the middle of the glass guide groove, and intervenes at 60%-80% of the glass lifting stroke, effectively compensating for the missing guiding effect due to the short front guide rail, equivalent to forming a 'virtual guide rail', thereby completely solving the problems of deviation and not entering the groove of the vehicle window glass at the end of the lifting due to insufficient guiding of the vehicle model, and especially improving the lifting reliability of the vehicle at high speed.

Description

Technical Field

[0001] This application belongs to the field of automotive body technology, and specifically relates to a door glass guide groove, a door, an automobile, and a method for manufacturing and assembling the same. Background Technology

[0002] In boxy SUVs, the front edge length (A) of the front door window frame is significantly shorter than the rear edge length (B), meaning the A / B ratio is typically less than 0.3. This results in insufficient guidance and restraint of the A-pillar rail on the front side during window operation, as the window rail is too short. When the window is nearly fully closed, the lack of sufficient guide length causes it to easily shift outwards, making it difficult to accurately and smoothly enter the window groove. At high speeds, external negative pressure exacerbates this outward shift, significantly increasing the risk of difficulty in closing the window or the window not fitting properly into the groove, impacting user experience and vehicle sealing performance.

[0003] Existing technologies are primarily designed for vehicles with large A-pillar angles, where the guiding effect is distributed throughout the entire window's lifting stroke or focuses on initial guidance. These solutions have limited effectiveness in addressing the specific technical problem of insufficient guiding force at the end of the window's lifting stroke due to a small A / B ratio, leading to uncontrollable window trajectory. Summary of the Invention

[0004] To address the aforementioned problems, the present invention provides a guide groove for a car door glass, comprising a groove body extending along its length, and a guide block provided on the groove body. The guide block is configured to laterally guide and correct the movement trajectory of the glass before the car window glass rises to the closed position.

[0005] Furthermore, the guide block is fixed at the middle position along the length of the trough body.

[0006] Furthermore, the guide block and the main body of the trough are integrated by continuous microwave vulcanization.

[0007] Furthermore, the guide block includes a steel frame and a guide block body covering the steel frame. The steel frame and the guide block body are injection molded together to form a guide block assembly, and the guide block assembly is vulcanized together with the trough body.

[0008] Furthermore, the guide block is positioned at 60% to 80% of the total travel of the window glass as it rises.

[0009] Furthermore, the guide block has a guide surface for guiding the glass, and when the groove is installed in the door, the guide surface has an angle of 15° to 25° with the glass plane.

[0010] Furthermore, the maximum outer contour of the guide block does not exceed the outer contour of the groove body.

[0011] Furthermore, the steel frame is provided with positioning holes and connection holes.

[0012] Furthermore, the steel frame surface is stamped with reinforcing ribs.

[0013] The present invention provides a vehicle door, including a door body and a window glass, and is equipped with a groove for guiding the door glass.

[0014] Furthermore, the door is a door with an A-pillar angle of less than 30°, and the ratio A / B of the front boundary length (A) to the rear boundary length (B) of the front door window frame is less than 0.37.

[0015] The present invention provides an automobile, including any of the above-mentioned doors.

[0016] This invention provides a method for manufacturing a guide block assembly, used to manufacture a guide block in a groove for guiding vehicle door glass, comprising: Provide steel frame; The guide block body material is injection molded and wrapped around the steel frame to form an integrated guide block assembly.

[0017] This invention provides an assembly method with a guide block groove, comprising: The guide block assembly, manufactured by the method of manufacturing the guide block assembly, is connected to the groove body with a portion of the lip cut off by microwave continuous vulcanization.

[0018] Compared with the prior art, this application has the following advantages: This invention adds a dedicated guide block to the glass groove body, which functions during the critical stage of the window's movement—specifically, the stage just before it is fully closed—to actively intervene and correct the glass's trajectory. This is equivalent to adding a dynamic guiding force application point in the middle to rear section of the glass's rising path, even when physical constraints exist (such as an insufficiently short front guide rail). This effectively compensates for the insufficient length of the front guide, ensuring the stability of the glass's movement at the end of its stroke, allowing it to be precisely guided into the groove, ultimately achieving complete and reliable window closure.

[0019] Other features and advantages of this application will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the application. The objectives and other advantages of this application may be realized and obtained by means of the structures pointed out in the description, claims and drawings. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figure 1-1 , Figure 2-1 , Figure 3-1 and Figure 4-1 This invention provides a groove for guiding a vehicle door glass 15. The groove mainly includes a groove body 14 and a guide block assembly.

[0025] The groove body 14 is an elongated strip-shaped component extending along the longitudinal direction of the vehicle (i.e., the length direction of the door), and is typically made of elastic materials such as EPDM (ethylene propylene diene monomer rubber). Its interior forms guide grooves for accommodating and guiding the window glass 15. A guide block assembly is fixedly installed at a specific position along the length of the groove body 14.

[0026] Specifically, such as Figure 1-1 , Figure 2-1 and Figure 5-1 As shown, the guide block assembly is preferably fixed at the middle position of the groove body 14. This position is chosen based on the analysis of the movement trajectory of the glass 15. For vehicle models with a small A-pillar inclination angle and a short front guide rail (A-pillar guide rail) length A, the glass 15 is prone to outward deviation in the latter half of its rising stroke due to the weakening of the front constraint. The function of the guide block assembly is to laterally guide and correct the movement trajectory of the window glass 15 before it rises to the closed position. The principle is that when the glass 15 reaches this position, the guiding surface of the guide block assembly contacts the side of the glass 15, applying a lateral component force pointing inward to the groove, thereby actively correcting the outward deviation tendency of the glass 15 caused by insufficient front guide length, ensuring that it moves along the preset trajectory.

[0027] Furthermore, such as Figure 2-1 and Figure 5-1 As shown, the guide block assembly and the groove body 14 are connected as one unit through a microwave continuous vulcanization process. This connection method ensures a firm and airtight bond between the guide block assembly and the groove body 14, and the connection is smooth, without interfering with the movement of the glass 15.

[0028] More specifically, the guide block assembly consists of a steel frame and a guide block body 11. The steel frame is preferably made of DC01 steel plate with a thickness of, for example, 0.5 mm, and its surface is stamped with irregularly shaped reinforcing ribs to increase structural rigidity and the contact area with the guide block body 11. The steel frame has two steel frame positioning holes (11a) (the radius of the steel frame positioning holes (11a) is 1.5 mm, and the distance between the two steel frame positioning holes (11a) is defined as 13 mm to ensure positioning accuracy) and multiple upper and lower connecting holes (11b) (up to 5, with a radius of 1.5 mm and appropriate hole spacing). The steel frame positioning holes (11a) are used to cooperate with the positioning pins of the injection mold when the guide block body 11 is injection molded onto the steel frame, ensuring the precise position of the steel frame in the mold cavity. Multiple upper and lower connecting holes (11b) in the steel frame are used to allow the material of the guide block body 11 to flow through the holes during injection molding, forming a mechanical interlocking structure. This significantly enhances the bonding strength and integrity between the steel frame and the guide block body 11, making them fused together as one unit during injection molding and more securely wrapped. The guide block body 11 is made of materials such as EPDM (ethylene propylene diene monomer rubber), and its surface is smooth and rounded. The following steps are used in manufacturing the guide block assembly: first, a steel frame is provided; then, the material of the guide block body 11 is injection molded over the steel frame, making the guide block and the steel frame injection molded into one unit, forming an independent and stable guide block assembly (such as...). Figure 3-1 (As shown). Subsequently, when assembling the complete flue, a portion of the lip of the flue body 14 is cut off at the location where the guide block assembly needs to be installed (the lip of a suitable size is cut off using a punching die). Then, this guide block assembly and the processed flue body 14 are placed together into a mold (i.e., the guide block assembly, in which the steel frame and the guide block body 11 are injection molded as one piece, and the punched flue body 14 are placed into a corner mold to connect them into a whole). Through the aforementioned microwave continuous vulcanization process, the guide block assembly is vulcanized as one piece onto the flue body 14, finally forming a complete flue assembly with guide blocks (as shown). Figure 1-1 and Figure 2-1 As shown). The guide block body 11 is provided with corresponding positioning holes (such as...). Figure 4-1 As shown, it is used for precise positioning in conjunction with the mold during the vulcanization process. It should be noted that the bright strip 13 serves as an external decorative element of the door gusset assembly. The portion of the bright strip 13 that interferes with the guide block body 11 is cut off, and it is then snapped onto the gusset body 14. This is the machining (cutting) performed to adapt to the newly added guide block.

[0029] Regarding the placement of the guide block assembly, calculations and experimental verification have shown that its optimal position corresponds to 60% to 80% of the total travel of the window glass 15 during its upward movement. Setting the guide intervention point at this location most effectively compensates for the insufficient length A of the front guide rail (A-pillar guide rail 31), applying corrective force at the initial stage when the glass 15's trajectory begins to show signs of instability, resulting in the best effect. In other words, the guide block is configured specifically to compensate for the lack of guiding effect due to the insufficient length of the front boundary of the front door window frame during the upward movement of the window glass 15.

[0030] like Figure 3-1 As shown, when the guide groove is installed on the car door, an angle α is formed between the guiding surface of the guide block body 11 and the plane of the window glass 15. This angle α is optimized and preferably 20° to ensure that the glass 15 has sufficient guiding space when it is about to contact the guide block, and more preferably within the range of 15° to 25°. This angle ensures that the glass 15 receives a smooth and effective guiding force when it is about to contact the guide block, with sufficient guiding component and without generating excessive resistance or wear due to an excessively large angle.

[0031] like Figure 1-1 and Figure 6-1 As shown, the maximum outer contour of the guide block assembly does not exceed the outer contour of the felt body 14. This design ensures that the entire felt assembly will not protrude excessively after installation, thus not obstructing the driver's side view, and also facilitates the packaging and transportation of the felt assembly.

[0032] Please continue reading. Figure 2-1 The present invention also provides a vehicle door. The vehicle door includes a door body (composed of an inner door panel 16, a door window frame reinforcing plate 17, etc.), a window glass 15, and a groove with a guide block as described in any of the above embodiments. The groove is fixedly installed on a window frame stop formed by the door window frame reinforcing plate 17, etc. The window glass 15 moves along a guide rail under the drive of a lifter. During the rising process, the edge of the glass 15 first contacts the guide block, and under the guidance of the guide block, changes its direction of movement, thereby smoothly and accurately embedding into the guide groove of the groove body 14, completing the closing process.

[0033] In particular, the guide block-equipped groove provided by this invention is especially suitable for vehicle doors with specific structures. For example... Figure 5-1As shown, the A-pillar angle of this type of vehicle (i.e., boxy and SUV bodies tend to have sharp lines and distinct angles, while the overall layout requires an extreme field of vision) is relatively small, usually less than 30°. This results in the front boundary length A of the front door window frame being significantly shorter than the rear boundary length B, with a ratio A / B less than 0.37, or even less than 0.3. Under this extreme ratio, traditional groove solutions cannot guarantee the stability of glass 15's lifting and lowering due to the excessively short front guide rail (A-pillar guide rail 31). The guide block assembly of this invention, functionally, adds a virtual guide rail 32 of length A to the A-pillar. This changes the effective guide length from A to (A+A'), allowing the ratio (A+A') / B to reach or exceed the threshold required for stable operation of glass 15 (e.g., 0.37), perfectly solving the engineering challenges caused by shape limitations. This also makes the groove of the guide block more malleable.

[0034] Finally, the present invention also provides an automobile comprising the door described in any of the preceding claims. This automobile, by employing the guide block groove of the present invention in its door, effectively solves the problem of difficulty in raising the window glass 15 of vehicles with small A-pillar angles, such as those with a boxy shape, and the window not fitting properly into the groove during high-speed driving or normal closing, thereby improving the vehicle's sealing, sound insulation, and user experience.

[0035] Optionally, the guide block is not integrally connected to the felt body 14 via microwave continuous vulcanization, but rather uses a detachable mechanical connection. The guide block can be designed as an independent snap-fit ​​module, with pre-set slots or guide rails at corresponding positions on the felt body 14. The guide block is snapped into and locked onto the felt body 14 by sliding, pressing, or rotating. Alternatively, the guide block can be fixed to specific positions on the felt body 14 or the door / window frame using screws, rivets, or other fasteners. This facilitates individual replacement, repair, or optional installation based on vehicle model configuration, improving modularity and after-sales maintenance convenience. Simultaneously, this connection method itself provides sufficient connection strength. It should be noted that at least one pair of mounting rails with slots or dovetail grooves can be molded on the inner side (the side facing the glass 15) or back of the felt body 14. Correspondingly, the base of the guide block is provided with a matching latch or slider. During installation, align the guide block's latch in a specific direction (such as perpendicular to the length of the groove) and push it into the groove of the groove body 14 until a "click" is heard or a clear limit is felt, indicating that the connection is complete. To ensure a secure connection, the end of the latch may be provided with a barb, and the groove may have a corresponding protrusion. Alternatively, the guide block can be directly fixed to the door window frame reinforcement plate 17 or the nut seat pre-embedded in the groove body 14 using countersunk self-tapping screws or plastic rivets, passing through the mounting holes on its base. This connection method facilitates the individual replacement of the guide block during after-sales maintenance and also supports selective installation based on vehicle model configuration.

[0036] Optionally, the guide surface of the guide block is not a fixed-angle slope, but rather a movable or flexible structure. One or more freely rotating rollers (such as nylon or rubber-coated rollers) are mounted on the guide block. When the glass 15 rises, it contacts the rollers, resulting in low frictional resistance and smoother guidance, making it particularly suitable for high-speed lifting or scenarios with higher noise requirements. The guide surface of the guide block is made of a highly elastic, low-friction material (such as a specially formulated TPE), or has an internal cavity or elastic support structure. When the glass 15 contacts the guide block, the guide surface can deform to a certain extent, providing guidance force while absorbing impact and vibration, further reducing noise and wear on the glass 15. This reduces friction and wear between the glass 15 and the guide block, improving the smoothness and quietness of the lifting process and extending component life. It should be noted that the guide surface of the guide block can be constructed in the form of low friction or elastic buffer to optimize the guiding experience. One specific form is the roller-type guide: Inside the guide block body 11, a rotating shaft made of stainless steel or engineering plastic is set parallel to the plane of the glass 15. One or more rollers made of polyoxymethylene (POM) or coated with low-friction rubber are fitted onto the rotating shaft. The roller portions are exposed on the guiding surface of the guide block. When the glass 15 rises and contacts the guide block, it drives the rollers to rotate, converting sliding friction into rolling friction, significantly reducing motion resistance and frictional noise. Another specific form is the elastic buffer-type guide: The guide block body 11 is integrally injection molded from a thermoplastic elastomer (TPE) with high resilience and moderate hardness. Its interior can be designed with a mesh or honeycomb hollow structure, or an elastic pad such as silicone can be placed between its rigid base and the contact surface. When the glass 15 contacts the guiding surface, this elastic structure can undergo controllable, minute deformation, providing the necessary guiding force while effectively absorbing the instantaneous impact and vibration of the glass 15, achieving a gentler and quieter guiding process.

[0037] Optionally, the guide block is not always in the working position, but intervenes "actively" or "passively" when the glass 15 rises to a specific position. In its initial position (below the glass 15), the guide block is retracted or flat, not interfering with the normal raising and lowering of the glass 15. When the glass 15 rises and pushes the trigger mechanism at its bottom, the guide block flips up to the working angle under the action of a linkage or torsion spring mechanism, guiding the subsequent travel of the glass 15. The guide block has a built-in miniature electromagnet or is driven by a miniature motor. When vehicle sensors (such as a vehicle speed sensor or a glass 15 position sensor) detect that the vehicle is traveling at high speed and the glass 15 has risen to a preset position (e.g., 70% of the travel), the control system is energized to extend the guide block to the working position. After the glass 15 passes, the guide block retracts. This avoids unnecessary contact and friction during most of the glass 15's travel, providing guidance only when most needed, further optimizing the user experience and component durability. The electromagnetic drive solution achieves intelligent control, linked to vehicle status. Furthermore, the guide block can also be designed to enter the working position only when needed. A passive triggering mechanism is as follows: A guide block is hinged to the groove body 14 or the door frame via a pivot and is kept in a retracted state under the preload of a torsion spring (its guide surface is approximately parallel to the plane of the glass 15 or retracted within the groove contour). A small protrusion or bevel is provided as a trigger point on the upward path of the glass 15, slightly below the hinge point of the guide block. When the glass 15 rises and its lower edge contacts the trigger point, it pushes the guide block to overcome the torsion spring preload and rotate around the pivot to a preset working angle (e.g., 20°), thereby guiding the subsequent travel of the glass 15. After the glass 15 passes, the guide block automatically returns to the retracted state under the action of the torsion spring. An active triggering mechanism involves an electronic control unit: the guide block is connected to a miniature linear motor or solenoid drive mechanism. The vehicle bus receives position signals from the Hall sensor of the window 15 lifter motor. When it determines that the window 15 has risen to a predetermined stroke (e.g., 65%) and the vehicle speed signal is higher than a set threshold (e.g., 80 km / h), the control unit sends a command to the drive mechanism to push the guide block to the working position. After the window 15 is fully closed, the guide block automatically retracts. This method realizes intelligent on-demand activation of the guiding function. It should be noted that the function of the guide block can also be integrated with other existing components of the door to simplify the structure. One way is to integrate it with the window sill sealing strip: the sealing strip at the water cutter (window sill) of the door is locally thickened and reshaped at the position corresponding to the middle of the rising path of the window 15. The inner contour of this thickened part is specially designed to have a guide slope, so that it can perform the sealing function while also guiding the end of the window 15. The guide slope can be integrally extruded with the sealing strip body. Another way is to integrate it with the de-icing / defogging function: for vehicles in cold regions, the guide block body 11 can be embedded with a heating element made of resistance wire or conductive film.The electrodes of the heating element are connected to the power supply and control module inside the door via flexible wires. In low-temperature environments, when the window glass 15 is raised or lowered, or when the vehicle's defrosting function is activated, the heating element is powered on to heat the guide block and the local area of ​​the glass 15 it contacts, preventing a sharp increase in friction or jamming between the glass 15 and the guide block due to frost or ice, thus ensuring smooth raising and lowering.

[0038] Optionally, the guide block is not a single functional component but is integrated with other door functional components. The guide block is integrally molded with the door seal 19 or window sill seal. This integrated component retains the waterproof, dustproof, and soundproof functions of the seal, while also being thickened or having a special contour at specific locations to guide the glass 15 at its end. For vehicles in cold regions, heating wires can be integrated inside or on the surface of the guide block. In winter, in addition to its guiding function, the guide block can also locally heat the area of ​​the glass 15 it contacts, preventing icing or fogging in this critical guiding area and ensuring smooth lifting. This functional integration of components saves installation space and reduces system complexity and overall cost. The integrated heating function solves derivative problems in specific environments, improving the applicability of the solution.

[0039] Optionally, a method for controlling the lifting of a vehicle window glass 15 is applied to a vehicle door equipped with a guide block groove as described in any of the above embodiments. The method monitors the lifting speed of the window glass 15 and / or the load current of the motor. When the glass 15 rises to the guide block's operating area (e.g., 60%-80% of the travel), if an abnormal decrease in the speed of the glass 15 or an abnormal increase in the motor current is detected (indicating that the glass 15 may encounter significant resistance or has deviated), the lifting motor is briefly increased in torque or a "jog" mode (short, intermittent force application) is adopted to assist the glass 15 in overcoming resistance and smoothly passing the position under the guidance of the guide block. Combining mechanical guidance with an electronic control strategy forms a "mechatronics" solution, further improving the success rate and reliability of the glass 15 entering the groove under extreme conditions (such as icing, mud, or severe deformation). Specifically, the method includes the following steps: S1. Monitor the operating parameters of the window glass 15 lifting motor in real time, including at least the motor drive current and / or the real-time lifting speed of the glass 15 calculated by the Hall sensor. S2. When it is determined that the glass 15 has entered the preset "guide block action area" (corresponding to 60%-80% of the stroke) based on the initial position of the glass 15 and the running time (or Hall pulse count), a targeted control strategy is activated. S3. In this area, if the driving current value of the motor is continuously higher than the first threshold (indicating increased resistance), and / or the rising speed of the glass 15 is continuously lower than the second threshold (indicating insufficient lift), the control unit determines that the glass 15 may encounter greater resistance when passing through the guide block. S4. Once the above judgment is made, the control unit temporarily increases the drive duty cycle or voltage of the motor, so that its output torque increases by a set value in a short time (e.g., 0.5-2 seconds) to help the glass 15 overcome resistance and smoothly pass over the guide block area. S5. If the current or speed returns to normal during or after the torque enhancement period, normal lifting control is resumed. This method forms a synergistic solution of "mechanical guidance (guide block) + electronic assistance," which greatly improves the reliability of glass 15 entering the slot under extreme conditions.

[0040] In summary, the guide block and the steel frame are integrally injection molded into a guide block assembly. A portion of the lip is removed from the guide block at the location where it needs to meet the corner of the groove body 14. The guide block assembly and the groove are then continuously vulcanized using microwaves to form a groove assembly. The groove assembly is installed on the door / window frame stop. During the upward movement of the glass 15, it first contacts the guide block, and with the guidance of the guide block, the glass 15 smoothly enters the groove during its ascent. This differs from traditional grooves without guide blocks: with the groove assembly installed on the door / window frame stop, the glass 15 enters the groove solely through the guidance of the front and rear guide rails during its ascent.
