Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of vehicle engineering, and particularly relates to an outer water cutting sealing strip device and a vehicle. BACKGROUND

[0002] The vehicle with frameless doors is favored due to its simple and streamlined appearance. The sealing structure of the upper edge and the side edge of the conventional door is moved to the upper edge and the side edge of the door hole of the vehicle body, so that the upper part of the door is not provided with a sealing structure, and only an outer water cutting sealing strip structure is arranged in the middle part of the door body to contact and seal the side windshield. The overall structure is simple and beautiful. In the sealing state of the door, the top and side part of the side windshield on the door body are embedded in the sealing structure of the upper edge and the side edge of the door hole of the vehicle body. When the door is opened, the side windshield on the door body needs to be moved downward to be separated from the sealing structure, and then the door can be opened.

[0003] The outer water cutting sealing strip structure is provided with an outer water cutting sealing strip, such as an elastic lip, which is connected at the root to the main structure in the door body and can abut against the side windshield of the door to realize contact sealing. In an extremely low temperature environment such as freezing rain, the elastic lip will freeze with the side windshield, so that the side windshield cannot be moved, and the door cannot be opened smoothly, which easily causes damage to the door structure due to forced opening. On the other hand, the elastic lip needs a certain amplitude of swing space to form a continuous elastic pressure on the side windshield. Therefore, a groove cavity is formed between the root of the elastic lip and the main structure to facilitate the swing of the elastic lip. However, the groove is prone to water accumulation, and after freezing and expansion, it is easy to press the elastic lip, which greatly increases the force on the side windshield and the contact friction, seriously hindering the up and down movement of the side windshield. The frozen ice lumps seriously affect the swing of the elastic lip, thus maintaining this hindering state, and also producing continuous friction noise during the movement of the side windshield. SUMMARY

[0004] The application provides an outer water cutting sealing strip device and a vehicle, which aims to at least solve the technical problem that the side windshield of the frameless door and the outer water cutting sealing strip are difficult to move relative to each other in an extremely low temperature environment, or even cannot move; so as to achieve the technical effects of keeping the side windshield moving smoothly in an ice freezing environment, the convenience of opening and closing the door, and reducing noise.

[0015] In some embodiments, the contact sealing part is provided with an arc-shaped water-repellent surface protruding from the side edge part and the top end surface of the second end of the elastic lip, and the top end of the arc-shaped water-repellent surface is connected to the top end surface of the second end of the elastic lip through a flow guide inclined surface.

[0016] In some embodiments, the top surface of the first flow guide part is provided with a first flow guide surface, the top surface of the second flow guide part is provided with a second flow guide surface, and when the first flow guide part and the second flow guide part abut against each other, the first flow guide surface and the second flow guide surface smoothly connect, and the top end surface of the second end of the elastic lip smoothly connects with the first flow guide surface.

[0017] In some embodiments, the first flow guide is arranged in a ladder-like shape, the bottom surface of the second flow guide contacts the top surface of the lower step area of the ladder-like shape, the end surface of the second flow guide abuts the side surface of the upper and lower step connection area of the ladder-like shape, and the top surface of the upper step area of the ladder-like shape is smoothly connected with the top surface of the second flow guide.

[0027] The outer water-cutting sealing strip device and the vehicle provided by the embodiments of the present application, by arranging an elastic lip capable of elastically swinging on the main body to elastically abut against the side windshield of the frameless door to realize the function of contact sealing, and by connecting a first flow guide to the swinging end of the elastic lip and arranging a second flow guide on the main body, when the elastic lip abuts against the side windshield, the first flow guide and the second flow guide can abut to form a blocking sealing structure, which blocks and seals above the groove part between the root of the elastic lip and the main body, blocks rain and snow from falling, greatly reduces the risk of water accumulation, thereby avoiding the formation of a large swollen ice block in an extreme freezing environment to excessively press the elastic lip, greatly increasing the pressure acting on the side windshield, thereby avoiding increasing the frictional force exerted by the elastic lip on the side windshield, so that the smoothness and flexibility of the movement of the side windshield can be maintained, the difficulty of movement in a freezing environment is reduced, and excessive noise is also avoided to a certain extent.

[0040] With reference to the drawings and specific examples, the technical solutions in the embodiments of the present application will be described in detail.

[0041] Furthermore, reference numerals and / or letters can be repeated in different instances in this application for the sake of simplicity and clarity and such repetition is not to be construed as indicating an underlying relationship between the various embodiments and / or arrangements discussed. Moreover, specific examples of various processes and materials have been provided herein, but one skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0042] The present application will be described below in conjunction with the accompanying drawings and specific examples:

[0043] The side windshield of the frameless door is embedded in the door body and can be raised from the door body. The outer water cutting sealing strip device is arranged between the door body and the side windshield to contact and seal the gap therebetween. A sealing slot is also arranged at the upper edge of the door opening of the vehicle body, and when the door is closed, the side windshield can be raised and embedded in the sealing slot to achieve sealing of the upper edge of the door body. In the implementation of the door opening operation, the side windshield needs to be moved downward by a certain amplitude first to disengage the side windshield from the sealing structure on the vehicle body, so that the door can be smoothly opened. Conversely, in the door closing operation, the side windshield also needs to be moved downward first to disengage the sealing structure at the upper part of the door opening of the vehicle body, and then the door body is buckled, and then the side windshield is moved upward to engage the sealing structure, so that the entire door closing and window closing operation can be completed.

[0044] However, in an extremely low temperature environment such as low temperature, freezing, freezing rain, etc., the outer water cutting sealing strip directly contacting the side windshield, i.e. the elastic lip, in the outer water cutting sealing strip device is easy to form a frozen layer between the contact side and the side windshield, freeze the two together, so that the side windshield cannot be normally moved, and thus the door body cannot be opened. On the other hand, the groove part formed between the root of the elastic lip and the main body is easy to accumulate rain and snow, and the water accumulated in the freezing environment will quickly freeze into ice lumps to fill the groove part and expand to press the elastic lip, so that the force of the elastic lip acting on the side windshield is greatly increased, and thus the frictional force between the elastic lip and the side windshield is also increased, making it very difficult for the side windshield to move up and down. Moreover, a relatively large frictional noise will be generated, especially in the case of low temperature frozen, frozen hard elastic lip, the hardness of the elastic lip is greatly increased, and the elastic lip directly abuts against the side windshield, which will generate a continuous sharp noise during the movement of the side windshield, and even scratch or damage the plating layer or film on the side windshield.

[0045] In order to maintain the smoothness of the side windshield moving in the extreme low temperature environment such as freezing rain and to solve the above technical problems to some extent, the application provides an outer water cutting sealing strip device, which achieves the technical effects of maintaining the smoothness of the side windshield moving, the convenience of opening and closing the door, and reducing noise, and improves the convenience and comfort of using the vehicle.

[0046] Referring to Figure 1 Specifically, the outer water cutting sealing strip device comprises a main body 10, an elastic lip 20, a first flow guide 30, a second flow guide 40, and a heating assembly 50.

[0047] The main body 10 serves as the basic carrier of the entire device, carries other structural members, and is fixed to the door as a whole, serving as the basis for the sealing operation of the outer water cutting sealing device. Generally, the main body 10 should be configured with an embedded support skeleton 11 as the central load-bearing structure, and fastening structures can be provided to adapt to the corresponding fixing structures and fasteners fixed to the door.

[0048] In order to realize the contact sealing function of the side windshield 80 of the door, the first end 21 of the elastic lip 20 is fixed to the main body 10, the side edge part of the second end 22 of the elastic lip 20 is provided with a contact sealing part 24, and in the case of the side windshield 80 rising, the contact sealing part 24 abuts against the side windshield 80 to realize contact sealing; and the elastic lip 20 can elastically swing around the first end 21 of the elastic lip, i.e. swing relative to its root, so as to be able to follow the micro swing during the movement of the side windshield 80, to keep the stability of the elastic force acting on the contact sealing part 24, so that the contact sealing part 24 stably and elastically contacts the side windshield 80, maintaining a stable sealing effect.

[0049] In order to inhibit the problem of the accumulation of rain and snow in the groove portion 12 between the first end 21 of the elastic lip 20 and the main body 10, which causes the difficulty of moving the side window 80 and the generation of moving noise, by fixing the first flow guide 30 at the second end 22 of the elastic lip 20 and fixing the second flow guide 40 on the main body 10, and by the design of the fixed position, the first flow guide 30 can abut on the second flow guide 40 when the contact sealing portion 24 abuts on the side window 80, thereby forming an abutting sealing shielding structure above the groove portion 12 to block the groove portion 12 between the elastic lip 20 and the main body 10, shield rain and snow, and avoid the accumulation of rain and snow in the groove portion 12, thereby greatly solving the problem of the freezing of ice lumps in the groove portion 12 affecting the swing of the elastic lip 20. Thus, the problem of the excessive compression of the elastic lip 20 on the side window 80 caused by the frozen ice lumps is avoided, and the hindering of the movement of the side window 80 by the elastic lip 20 in the ice frozen environment is reduced.

[0050] Considering that the groove portion 12 is the lowest point of the entire outer water cutting sealing strip device, the water seeped between the first flow guide 30 and the second flow guide 40 or the water in other areas can still be collected in the groove portion 12, thereby causing the risk of freezing into ice lumps. Therefore, the heating assembly 50 can be fixed in the groove portion 12, a stable relatively high temperature field is formed in the relatively closed cavity of the groove portion 12 by the heating assembly 50, the existing ice lumps are directly melted, and the freezing process in the range of the groove portion 12 is further inhibited. At the same time, the relatively high temperature field can radiate heat to the surrounding, thereby enabling the overall temperature of the elastic lip 20 to rise, the temperature of the contact sealing portion 24 also rises accordingly, thereby thawing the frozen layer between the contact sealing portion 24 and the side window 80 and further limiting the generation of the frozen layer again, thereby enabling the smoothness of the movement of the side window 80 to be maintained.

[0051] It is worth noting that the relatively high temperature field can maintain the elastic state of the elastic lip 20 to a certain extent, avoid the freezing of the elastic lip 20 to be straight and rigid in an extremely low temperature environment, thereby enabling the elastic lip 20 to maintain the function of elastic swing, maintain the sealing effect, and inhibit the adverse effects on the movement of the elastic lip 20, and also inhibit noise to a certain extent.

[0052] In some embodiments, in view of the risk of seepage of the contact sealing structure between the first flow guide 30 and the second flow guide 40, in order to further reduce the water accumulation in the groove portion 12, a pocket 60 can be arranged on the main body 10, and the pocket 60 is arranged above the groove portion 12, and the pocket 60 is located below the abutting surface of the first flow guide 30 and the second flow guide 40, and is used to collect the seepage water; thus, the water seeped from the abutting surface of the first flow guide 30 and the second flow guide 40 can be mainly collected above the groove portion 12 by the pocket 60, and will not be collected in large amount into the groove portion 12 below, so that even if there is a small amount of seepage, it will not cause a large amount of water accumulation in the groove portion 12, and even if it is frozen into an ice block, the pressure on the elastic lip 20 is relatively small.

[0053] On the other hand, in view of the fact that the pocket 60 is always located in the cavity space of the groove portion 12, and is not a stable drainage structure, and the accumulated water always has the risk of overflowing to the groove portion 12 with the movement of the vehicle, a drainage port can be arranged on the pocket 60, and the drainage port is arranged outside the groove portion 12, so that the collected water can be drained out of the space of the groove portion 12, to further reduce the risk of freezing of the water accumulation in the groove portion 12.

[0054] In some embodiments, since there can be a certain amount of water in the pocket 60, in order to accelerate the drainage of the accumulated water in the pocket and avoid freezing, the heating assembly 50 can be fixed on the side edge portion of the elastic lip 20 close to the pocket 60, so that the heating assembly 50 can heat the local area where the pocket 60 is located at a close distance, accelerate the melting of the frozen water in the pocket 60, and drain or avoid freezing.

[0055] In some embodiments, in order to accelerate the melting of the frozen layer between the contact sealing portion 24 and the side windshield 80, and improve the door opening speed, the heating assembly 50 can be arranged in the angle shielding area of the first flow guide 30 and the elastic lip 20, so that the heating assembly 50 is arranged close to the contact sealing portion 24, the distance between the heat source and the frozen layer is shortened, and the thawing efficiency is improved.

[0056] At the same time, the heating assembly 50 is away from the groove portion 12, so as to avoid the accumulated water from soaking the heating assembly 50 and causing functional failure.

[0057] It is worth noting that the heating assembly 50 is arranged in the angle shielding area of the first flow guide 30 and the elastic lip 20, and can be away from the seepage water drops and water flow to a certain extent, so as to avoid directly hitting the heating assembly.

[0058] In some embodiments, the heating assembly 50 can be arranged as a heating sheet attached to the elastic lip 20; and the heating sheet can be further arranged as a plurality of independent sheet bodies arranged at intervals along the length direction of the elastic lip 20, forming a plurality of heat source areas in the cavity space of the groove portion 12, so that the temperature of the whole cavity area is substantially equivalent, and the heating temperature can also be flexibly adjusted for group control, so as to balance the energy consumption and the larger temperature adjustment range.

[0059] Of course, the heating sheet can also be arranged as an integrated sheet body covering the elastic lip 20 in a large range, which to some extent simplifies the structure and facilitates installation and control.

[0060] It is worth noting that considering that the main deformation area of the elastic lip 20 is the root area close to the first end 21 thereof, in order to avoid the influence of the fixing of the heating assembly 50 on the deformation action, the heating sheet can be arranged close to the middle or the second end 21 of the elastic lip 20; or the heating sheet can also be arranged as a spring sheet or other sheet-shaped structure of elastic material with certain elasticity and heat conduction.

[0061] In some embodiments, considering the production and assembly process and the convenience requirement, the heating assembly 50 can be bonded to the elastic lip 20.

[0062] In some embodiments, in order to improve the sealing performance and reliability of the abutment seal between the first flow guide 30 and the second flow guide 40, a sealing boss 70 can be arranged on the abutment surface of the first flow guide 30 and the second flow guide 40, so as to form a seepage prevention dam between the first flow guide 30 and the second flow guide 40, prolong the seepage path, increase the seepage resistance, and thus strengthen the contact sealing performance.

[0063] Generally, the sealing boss 70 can be arranged on one or both of the first flow guide 30 and the second flow guide 40, which can be flexibly arranged as needed.

[0064] It is worth noting that the water film thickness between the first flow guide 30 and the second flow guide 40 can also be kept at a low level and irregular in shape by the sealing boss 70, and even if it is frozen, it can be easily destroyed under the action of the elastic reset force of the elastic lip, without causing continuous impact on the swing of the elastic lip.

[0065] At the same time, due to the existence of the sealing boss 70, the contact surface of the first flow guide 30 and the second flow guide 40 is uneven, so that when the first flow guide 30 and the second flow guide 40 relatively move, continuous sharp friction noise will not be generated.

[0066] In some embodiments, in order to reduce the seepage between the first flow guide 30 and the second flow guide 40, the drainage effect of the surfaces of the two can also be increased; specifically, a first flow guide surface 31 with a hydrophobic flow guide effect can be provided on the top surface of the first flow guide 30, and a second flow guide surface 41 with a hydrophobic flow guide effect can be provided on the top surface of the second flow guide 40, and through profile design, when the first flow guide 30 and the second flow guide 40 abut and seal, the first flow guide surface 31 and the second flow guide surface 41 smoothly connect, so that water flowing over the top surfaces of the first flow guide 30 and the second flow guide 40 can be quickly drained.

[0067] Generally, in order to achieve smooth connection of the first flow guide surface 31 and the second flow guide surface 41, the first flow guide 30 can be provided as a ladder-shaped special-shaped member, that is, the two end portions of the first flow guide 30 are not flat, but have a height difference in the length direction, and are connected by an abutment portion, thereby forming a ladder-shaped structure. When the first flow guide 30 and the second flow guide 40 abut, the bottom surface of the second flow guide 40 abuts on the lower step portion of the ladder-shaped special-shaped member, and the end surface of the second flow guide 40 abuts on the connecting portion between the two steps, so that the top surface of the second flow guide 40 and the upper step of the ladder-shaped special-shaped member smoothly connect, that is, the second flow guide surface 41 and the first flow guide surface 31 smoothly connect, thereby accelerating drainage and avoiding the formation of a groove in the abutment portion to store a small amount of water, causing continuous seepage.

[0068] Generally, the bottom surface of the second flow guide 40 is stacked on the top surface of the lower step area of the first flow guide 30, and correspondingly, the first flow guide 30 and the second flow guide 40 are elastic members, and a certain elastic contact pressure is maintained between the two, thereby achieving stable sealing effect.

[0069] Correspondingly, the pocket 60 can be correspondingly provided directly below the tail end portion of the first flow guide 30, thereby aligning and receiving the seepage water flowing down the first flow guide 30, thereby stably collecting seepage water.

[0070] In some embodiments, in order to improve fault tolerance, avoid mutual avoidance adaptation ability due to excessive strength, and in view of the need for separable abutment sealing of the first flow guide 30 and the second flow guide 40, the hardness of the elastic lip 20 can be set to be greater than the hardness of the second flow guide 40, and correspondingly, the hardness of the first flow guide 30 integrated with the elastic lip 20 is also greater than the hardness of the second flow guide 40, so that the elastic lip 20 can have sufficient hardness and elastic contact force applied to the side windshield under the premise that the elastic lip 20 can have sufficient hardness and elastic contact force applied to the side windshield, and the first flow guide 30 and the second flow guide 40 can also form an abutment under the condition of hardness difference, so that the second flow guide 40 with smaller hardness can adapt to the first flow guide 30 with relatively larger hardness, that is, when the two abut, the second flow guide 40 is relatively easy to deform to adapt to the position and posture of the first flow guide 30 which is not easy to deform, so as to maximize the stable surface contact of the two and ensure the sealing reliability.

[0071] Specifically, in the present embodiment, the hardness range of the second flow guide 40 is set to Shore A 35±5 degrees, and correspondingly, the hardness range of the elastic lip 20 and the first flow guide 30 integrated thereon is Shore A 65±5 degrees, so as to balance the strength requirement of the elastic lip 20 for contact sealing and the adaptation ability requirement of the first flow guide 30 and the second flow guide 40.

[0072] In some embodiments, in order to reduce the freezing strength of the contact sealing portion 24 and the side windshield 80, an arc-shaped hydrophobic surface 24a protruding from the side edge portion and the top end face of the second end 22 of the elastic lip 20 can be provided on the contact sealing portion 24, so that when the arc-shaped hydrophobic surface 24a abuts on the side windshield 80, the contact surface will be limited to only a part of the arc-shaped surface, so that even if it freezes, the area will not be very large, and the moving resistance will not be very large, the area required for ice melting will be smaller, and the ice melting efficiency will be improved.

[0073] Generally, the top end of the arc-shaped hydrophobic surface 24a and the top end face 26 of the second end 22 of the elastic lip 20 can be connected by a flow guide slope 25, so that the top end of the arc-shaped hydrophobic surface 24a is as close to the side windshield as possible, thereby reducing the gap between the top end region of the arc-shaped hydrophobic surface 24a and the side windshield 80, thereby reducing the amount of water remaining, reducing seepage along the side windshield 80, and reducing the freezing thickness, thereby facilitating efficient ice melting.

[0074] Correspondingly, the top end face 26 of the second end of the elastic lip 20 and the first flow guide surface 31 can be smoothly connected to realize the integration of the outer water cutting sealing strip device outer surface flow guide surface, thereby promoting drainage and avoiding water remaining on the surface.

[0075] In some embodiments, in order to reduce the contact friction between the arc-shaped hydrophobic surface 24a and the side window 80, a flocked layer 23 can be arranged on the arc-shaped hydrophobic surface 24a.

[0076] In some embodiments, in order to strengthen the waterproof sealing performance of the arc-shaped hydrophobic surface 24a, a hydrophobic coating can be attached to the flocked layer 23; and the hydrophobic coating can be specifically set as a KUOPOE coating TP18-810N; of course, other hydrophobic materials can also be used, which are only used as examples and are not limited.

[0077] Generally, the flocked layer 23 can cover the side of the elastic lip 20 close to the side window, so that when the side window 80 is lifted from the inside of the door and just contacts the elastic lip 20, the side window 80 can be moved in a low sliding friction state, ensuring smooth movement and reducing noise.

[0078] Similarly, considering that the elastic lip 20 is an elongated element, and the structure of the pocket 60 is also small, in order to facilitate assembly, the pocket 60 can be directly integrally formed on the main body 10, thereby reducing the assembly difficulty.

[0079] Similarly, the first flow guide 30 and the elastic lip 20 can also be integrally formed, and the second flow guide 40 and the main body 10 can also be integrally formed.

[0080] The embodiments of the present application also provide a vehicle configured with the above-mentioned outer water cutting sealing strip device, and the elastic lip 20 can be specifically installed on the door and abuts against the side window 80.

[0081] On the other hand, the heating assembly 50 can be connected with the vehicle power supply system to obtain energy.

[0082] It is worth noting that the heating assembly 50 can be configured with a separate control switch, which is actively operated by an operator to implement ice melting operation, or continuously turned on to inhibit icing.

[0083] The heating assembly 50 can also be integrated and connected to the vehicle ECU to realize automatic or semi-automatic operation under the control of the vehicle ECU.

[0084] For example, the heating time of the heating assembly 50 can be set, and the heating duration can be controlled by the vehicle ECU. The ambient temperature and humidity can also be detected by the vehicle temperature sensor, and when the temperature and humidity reach the starting conditions, the heating assembly 50 can be periodically started to achieve the effect of ice melting or icing inhibition.

[0085] Therefore, the outer water cutting sealing strip device and the vehicle in the embodiment achieve the function of contact sealing by arranging the elastic lip that can elastically swing on the main body to elastically abut against the side windshield of the frameless door; the first flow guide is connected at the swing end of the elastic lip, and the second flow guide is arranged on the main body, so that when the elastic lip abuts against the side windshield, the first flow guide and the second flow guide can abut to form a blocking sealing structure, which blocks the above of the groove part between the root of the elastic lip and the main body, blocks the rain and snow from falling, and greatly reduces the risk of water accumulation, thereby avoiding the formation of a large ice block that excessively presses the elastic lip in an extremely cold environment, greatly increasing the pressure acting on the side windshield, and further avoiding the increase of the friction force of the elastic lip applied to the side windshield, so that the smoothness and flexibility of the side windshield movement can be maintained, the difficulty of movement in the freezing environment is reduced, and excessive noise is also avoided to a certain extent. On the other hand, by arranging the heating assembly in the groove part, a relatively high-temperature environment can be formed in the relatively closed groove part cavity space, which can melt the existing ice block formed by the water accumulation in the groove part and inhibit the re-icing; and through the way of wide heat radiation of the relatively high-temperature environment, the temperature of the whole elastic lip is increased and maintained at a relatively high temperature, so that the melting of the frozen layer between the elastic lip and the side windshield can be efficiently promoted, and the re-icing of the frozen layer is inhibited, thereby avoiding the freezing of the elastic lip and the side windshield again, to effectively maintain the smoothness of the side windshield movement; at the same time, since the elastic lip is in a relatively high-temperature state, it can maintain a certain elastic deformation ability in an extremely low-temperature environment, and can adaptively swing with the movement of the side windshield, thereby avoiding the formation of a rigid state that abuts against the elastic lip and causes sharp friction noise, or even scratching the structure such as the plating film on the sliding side windshield.
