Description
Technical Field
[0001] The utility model relates to the technical field of vehicle parts, and particularly relates to a protection structure for a carriage ventilation opening.
[0002] The utility model also relates to a vehicle provided with the above protection structure for a carriage ventilation opening. Background Art
[0003] During the driving process of a vehicle, it is necessary to keep the air inside the vehicle in a flowing state. Therefore, carriage ventilation openings are designed on vehicles. On the one hand, the carriage ventilation openings here can ensure ventilation when the vehicle is in the external circulation of the air conditioner, and the air blown in by the air conditioner will be discharged through the carriage ventilation openings. On the other hand, when the vehicle door is closed instantaneously, the pressure inside the vehicle will increase suddenly, which may cause ear discomfort. In this case, the carriage ventilation openings can play a role in pressure relief.
[0004] Since the carriage ventilation openings are usually arranged on the rear bulkhead of the vehicle and are set at a relatively low position. There is a bumper beam or a towing structure at the rear of the carriage ventilation openings. When the vehicle collides and the protective cover bears the extrusion force of the bumper beam or the towing structure, it is easy to damage the rear bulkhead or the structure of the carriage ventilation openings, affecting the ventilation effect inside the carriage. Summary of the Utility Model
[0005] In view of this, the utility model aims to propose a protection structure for a carriage ventilation opening, so as to effectively protect the structure of the carriage ventilation opening when the protective cover of the vehicle is subjected to external extrusion force during a collision.
[0006] To achieve the above object, the technical solution of the utility model is realized as follows:
[0007] A protection structure for a carriage ventilation opening, comprising a protective cover arranged at the carriage ventilation opening;
[0008] A ventilation channel is formed inside the protective cover, and one end of the protective cover is connected to the carriage ventilation opening, and the other end forms an extending end extending outwards;
[0009] The protective cover is provided with a collapse structure, and when the protective cover is subjected to external extrusion force, at least some positions at the extending end can collapse and deform under the guidance of the collapse structure.
[0010] Further, the protective cover comprises a first part and a second part connected to each other; one end of the first part is connected to the carriage ventilation opening, and the second part extends obliquely upwards relative to the first part and forms the extending end.
[0011] Further, a notch is provided at the end of the extending end, the notch is horizontally arranged, and the extending end upper part and the extending end lower part located on both sides of the notch are separated on the second part.
[0012] Furthermore, the crushing structure is arranged on the second part and at the root position above the extension end. When the protective cover is subjected to an external squeezing force, the upper part of the extension end can be crushed and deformed under the guidance of the crushing structure.
[0013] Furthermore, the crushing structure adopts thin-walled connecting ribs arranged on the second part, and the ends of the thin-walled connecting ribs extend to the edge of the notch.
[0014] Furthermore, exhaust holes communicating with the inside of the ventilation channel are arranged on the protective cover.
[0015] Furthermore, the exhaust holes are located at the top of the protective cover, are arranged close to the connection position between the first part and the second part, and the exhaust holes are multiple and arranged at intervals.
[0016] Furthermore, a rib arranged circumferentially along the vehicle compartment ventilation opening is provided at one end of the first part connected to the vehicle compartment ventilation opening; connection lugs for connecting the protective cover to the vehicle compartment ventilation opening are provided on the rib.
[0017] Furthermore, the protective cover is integrally formed; and / or, sound-absorbing materials are provided on the inner wall of the ventilation channel.
[0018] Compared with the prior art, the present utility model has the following advantages:
[0019] For the protective structure of the vehicle compartment ventilation opening described in the present utility model, through the protective cover arranged at the vehicle compartment ventilation opening, the protective cover can be used to better protect the vehicle compartment ventilation opening, and a crushing structure is arranged on the protective cover. When a vehicle collision occurs and the protective cover is subjected to an external squeezing force, the extension end of the protective cover can be crushed and deformed under the guidance of the crushing structure, thereby preventing damage to the rear body panel or the vehicle compartment ventilation opening structure, and thus ensuring the ventilation effect of the vehicle compartment ventilation opening.
[0020] In addition, the protective cover includes a connected first part and a second part, and one end of the first part is connected to the vehicle compartment ventilation opening, and the second part extends obliquely upward relative to the first part to form an extension end, that is, the extension end is arranged obliquely upward. In this way, on the one hand, structures such as the anti-collision beam behind the vehicle compartment ventilation opening can be avoided, on the other hand, the discharge of gas in the vehicle compartment can be ensured, and it can also effectively prevent water from pouring into the vehicle compartment ventilation opening or splashing water from entering the vehicle compartment ventilation opening, preventing the corrosion of the vehicle body. The notch provided on the extension end can increase the contact area between the end port of the protective cover and the outside, which is beneficial to guiding the rapid discharge of gas in the ventilation channel.
[0021] Secondly, a crush structure is provided on the second part and is located at the root position above the extended end. In this way, when the protective cover is subjected to an external squeezing force, the upper part of the extended end can be crushed and deformed under the guidance of the crush structure, thereby preventing the vehicle compartment ventilation opening from being blocked and ensuring the ventilation performance of the vehicle compartment ventilation opening. The crush structure adopts thin-wall connecting ribs provided on the second part, which has a simple structure and is convenient for preparation and molding. Moreover, the end of the thin-wall connecting rib extends to the edge of the notch. Therefore, the characteristic that the structural strength of the notch edge is small and easy to deform can also be utilized to better guide the upper part of the extended end to be crushed and deformed.
[0022] Furthermore, exhaust holes are provided on the protective cover, which is beneficial to reducing the vehicle interior noise when the gas is depressurized. The exhaust holes are arranged at the top of the protective cover. While ensuring smooth exhaust, it can also prevent water from entering the vehicle compartment ventilation opening through the exhaust holes during the vehicle wading process. The exhaust holes are multiple and are arranged at intervals at the connection between the first part and the second part, which is convenient for the design and implementation of the exhaust holes and can further facilitate gas depressurization.
[0023] In addition, a convex rib arranged circumferentially along the vehicle compartment ventilation opening is provided at one end of the first part connected to the vehicle compartment ventilation opening, and connecting lugs are provided on the convex rib. In this way, not only can the structural strength of the protective cover itself be improved, but also a gap can be formed between the protective cover and the rear bulkhead, which is beneficial for water to flow out from this gap, thereby preventing water from entering the vehicle compartment ventilation opening from one end where the protective cover is connected to the vehicle body rear bulkhead. The protective cover is integrally formed, which is convenient for the processing and preparation of the protective cover. Sound-absorbing materials are provided on the inner wall of the ventilation passage, which is beneficial to improving the overall vehicle NVH (Noise, Vibration, Harshness) performance.
[0024] Another object of the present invention is to provide a vehicle, in which the vehicle compartment ventilation opening is provided with the vehicle compartment ventilation opening protection structure as described above.
[0025] By adopting the above-mentioned vehicle compartment ventilation opening protection structure, the vehicle of the present invention can effectively protect the vehicle compartment ventilation opening by using the protective cover provided at the vehicle compartment ventilation opening and the crush structure provided on the protective cover, ensure the ventilation performance of the ventilation opening, and has a good use effect.

[0037] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0038] Embodiment 1
[0039] This embodiment relates to a protective structure for a carriage ventilation opening. When a vehicle collides and the protective cover is extruded by an external force, it can effectively protect the structure after the carriage is ventilated, prevent damage to the structure of the carriage ventilation opening, and thus ensure the ventilation effect of the carriage ventilation opening.
[0040] In terms of the overall composition, as Figures 1 to 3 shown, the protective structure for the carriage ventilation opening in this embodiment includes a protective cover 1 provided at the carriage ventilation opening 2. Among them, a ventilation channel 10 is formed inside the protective cover 1, and one end of the protective cover 1 is connected to the carriage ventilation opening 2, and the other end forms an extended end 103 extending outward. In addition, a crush structure 104 is provided on the protective cover 1, and when the protective cover 1 is subjected to an external extrusion force, at least some positions at the extended end 103 can be crushed and deformed under the guidance of the crush structure 104.
[0041] The carriage ventilation opening 2 is generally provided on the rear panel of the vehicle and is set at a relatively low position. Generally, an anti-collision beam or a trailer hitch device is provided at the rear of the carriage ventilation opening 2. When the vehicle collides, the protective cover 1 located at the carriage ventilation opening 2 is easily subjected to the extrusion force of the anti-collision beam or the trailer hitch device, etc., resulting in damage to the rear panel or the structure of the carriage ventilation opening.
[0042] At this time, in this embodiment, the protective cover 1 provided at the carriage ventilation opening 2 can provide good protection for the carriage ventilation opening 2, and the crush structure 104 provided on the protective cover 1 can cause the extended end 103 of the protective cover 1 to be crushed and deformed under the guidance of the crush structure 104 when the vehicle collides and the protective cover 1 is subjected to an external extrusion force. Thus, the external extrusion force can be prevented from being transmitted forward to the rear panel or the carriage ventilation opening, effectively preventing damage to the rear panel or the structure of the carriage ventilation opening, and thus ensuring the ventilation effect of the carriage ventilation opening 2.
[0043] Specifically, continuing to refer to Figures 1 to 3 shown, in this embodiment, since the carriage ventilation opening 2 is arranged at a relatively low position, when the vehicle wades through water, water will be trapped by the rear bumper, and then the water will enter the vehicle through the carriage ventilation opening, thus causing a rust problem and affecting the safety of the vehicle. For this reason, as a preferred embodiment, the protective cover 1 of this embodiment includes a connected first part 101 and a second part 102. Among them, one end of the first part 101 is connected to the carriage ventilation opening 2, and the second part 102 extends obliquely upward relative to the first part 101 and forms an extended end 103.
[0044] The first part 101 is arranged to facilitate the connection between the protective cover 1 and the rear panel at the vehicle compartment ventilation opening 2. The second part 102 extends obliquely upward relative to the first part 101, that is, the extension end 103 is arranged to incline towards the top of the vehicle compartment. In this way, not only can structures such as the anti-collision beam behind the vehicle compartment ventilation opening 2 be avoided, but also when the structures near the vehicle compartment ventilation opening 2 are compact, it is convenient to arrange the protective cover 1. Moreover, while ensuring the discharge of the gas in the vehicle compartment, it can also effectively prevent water from surging into the vehicle compartment ventilation opening or splashing water from entering the vehicle compartment ventilation opening 2.
[0045] As a preferred implementation manner, still referring to Figures 1 to 3 As shown, in this embodiment, a notch 20 is provided at the end of the extension end 103. The notch 20 is horizontally arranged, and with the notch 20 as the boundary, the upper extension end 1031 and the lower extension end 1032 located on both sides of the notch 20 are separated on the second part 102. At this time, the notch 20 provided on the extension end 103 can increase the contact area between the port of the extension end of the protective cover 1 and the outside, so as to facilitate the rapid discharge of the gas in the ventilation channel.
[0046] During specific implementation, the notch 20 is provided on the side wall at the end of the extension end 103. And from the width direction of the vehicle compartment, the notch 20 is generally V-shaped, and the notch 20 separates the second part 102 into the upper extension end 1031 and the lower extension end 1032.
[0047] The collapsible structure 104 of this embodiment, still referring to Figures 1 to 3 As shown, the collapsible structure 104 is arranged on the second part 102 and is located at the root position of the upper extension end 1031. In this way, when the protective cover 1 is subjected to an external extrusion force, the upper extension end 1031 can collapse and deform under the guidance of the collapsible structure, so as to prevent the vehicle compartment ventilation opening 2 from being blocked and ensure the ventilation performance of the vehicle compartment ventilation opening 2.
[0048] Preferably, the collapsible structure 104 of this embodiment adopts a thin-wall connecting rib arranged on the second part 102, and the end of the thin-wall connecting rib extends to the edge of the notch 20. Based on the above setting of the notch 20, one end of the thin-wall connecting rib extends at the edge of the notch 20, and the other end is located at the root position of the upper extension end 1031. In this way, the characteristic that the structural strength of the edge of the notch 20 is small and easy to deform can be utilized to better guide the collapse and deformation of the upper extension end 1031. Moreover, adopting the structural form of the thin-wall connecting rib, its structure is simple and convenient for preparation and molding.
[0049] In this embodiment, the thickness of the thin-walled connecting rib is between 1 mm and 1.2 mm. Specifically, during implementation, the thickness of the thin-walled connecting rib can be set, for example, to 1 mm, 1.1 mm, or 1.2 mm, and preferably 1 mm. In this way, on the premise of ensuring the preparation and molding of the second part 102, the thickness of the thin-walled connecting rib is set to be relatively small, which can further facilitate the collapse and deformation of the upper part 1031 of the extending end.
[0050] On the basis that the second part 102 of the protective cover 1 extends obliquely upward relative to the first part 101, in this embodiment, an exhaust hole 105 communicating with the inside of the ventilation passage 10 is also provided on the protective cover 1. The setting of the exhaust hole 105 is beneficial to reducing the vehicle interior noise during gas pressure relief. And preferably, as Figure 2 and Figure 3 shown, the exhaust hole 105 is located at the top of the protective cover 1 and is arranged close to the connection between the first part 101 and the second part 102. In this way, while ensuring smooth exhaust, it can also prevent water from entering the vehicle compartment ventilation opening 2 through the exhaust hole 105 during the vehicle wading process. And the exhaust holes 105 are arranged in multiple intervals. The setting of multiple exhaust holes 105 can further facilitate gas pressure relief.
[0051] It should be noted that in this embodiment, the shape of the exhaust hole 105 can be set to be circular, polygonal, elliptical, strip-shaped, etc., and the number of exhaust holes 105 arranged can be one, two, or any other multiple. This embodiment does not make any limitations in this regard.
[0052] Refer to Figure 3 shown, in this embodiment, a rib 106 arranged along the circumferential direction of the vehicle compartment ventilation opening 2 is provided at one end of the first part 101 connected to the vehicle compartment ventilation opening 2, and a connecting lug 107 for connecting the protective cover 1 to the vehicle compartment ventilation opening 2 is provided on the rib 106. Specifically, during implementation, for example, projection welding bolts are provided on the rear panel, connection holes for inserting the projection welding bolts are provided on the connecting lug 107, and the protective cover 1 is screwed and fixed to the vehicle compartment ventilation opening 2 on the rear panel through nuts.
[0053] In this embodiment, through the provided rib 106, not only can the structural strength of the protective cover 1 itself be improved, but also a gap can be formed between the protective cover 1 and the rear panel to facilitate the drainage of water from this gap and prevent water from flowing into the vehicle compartment ventilation opening 2.
[0054] In addition, as a preferred embodiment, the protective cover 1 of this embodiment is preferably integrally formed, with a simple manufacturing process and convenient for forming and preparation. Additionally, also as a preferred embodiment, in this embodiment, sound-absorbing materials are also provided on the inner wall of the ventilation passage 10. In this way, the sound-absorbing characteristics of the sound-absorbing materials can be utilized to absorb noise (such as tire noise) to prevent the noise from directly entering the vehicle compartment ventilation opening 2, thereby facilitating the improvement of the vehicle's NVH (Noise, Vibration, Harshness) performance.
[0055] It should be noted that the above-mentioned sound-absorbing materials can be, for example, sound-absorbing cotton, sound-insulating damping felt, polyurethane foam plastic, etc. During specific implementation, the sound-absorbing materials can be adhered to the inner wall of the ventilation passage 10, that is, the inner wall of the protective cover 1, by means of adhesion.
[0056] For the vehicle compartment ventilation opening protection structure of this embodiment, when a vehicle collision occurs and the protective cover is subjected to an external extrusion force, the crush structure 104 on the protective cover 1 can be utilized to enable the extended end 103 of the protective cover 1 to crush and deform under the guidance of the crush structure 104. Thereby, damage to the rear bulkhead or the vehicle compartment ventilation opening structure can be prevented, thus playing a better protective role for the vehicle compartment ventilation opening 2, and the ventilation effect of the vehicle compartment ventilation opening 2 can also be ensured after the protective cover is deformed.
[0057] Embodiment 2
[0058] This embodiment relates to a vehicle, and the vehicle compartment ventilation opening 2 of this vehicle is provided with the vehicle compartment ventilation opening protection structure of Embodiment 1.
[0059] By adopting the vehicle compartment ventilation opening protection structure of Embodiment 1, when a vehicle collision occurs and the protective cover 1 is subjected to an external extrusion force, the crush structure 104 provided on the protective cover 1 can be utilized to enable the protective cover 1 to locally crush and deform, thereby effectively preventing damage to the rear bulkhead and the ventilation opening structure, and effectively protecting the vehicle compartment ventilation opening 2, ensuring the ventilation performance of the vehicle compartment ventilation opening 2, and further facilitating the improvement of the overall service life of the vehicle and the customer's use experience.
[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
