Description

Technical Field

[0001] The invention belongs to the technical field of automobiles, and in particular relates to an automobile hood. Background Art

[0002] Automobiles have coating performance requirements and collapse performance requirements for the front hood of automobiles, but in the prior art, the above two performance requirements are contradictory for the hood inner plate of the automobile front hood. On the one hand, during the coating process, after the front hood of the automobile is lifted to a certain angle, the coating support rod directly abuts and supports the hood inner plate of the automobile front hood. Therefore, the coating performance requires that the hood inner plate of the automobile front hood has a higher strength to avoid plastic deformation of the supporting position and the adjacent area on the hood inner plate of the front hood during the coating process; on the other hand, the collapse performance requires that the hood inner plate of the automobile front hood should not have too high strength, so that after the hood of the automobile hood collides with a pedestrian, the hood inner plate of the automobile front hood can be deformed and collapsed to reduce the damage to the pedestrian. In practice, it is difficult to find a balance point for the hood inner plate of the automobile front hood that simultaneously meets the coating performance requirements and the collapse performance requirements. Summary of the invention

[0003] The object of the present invention is to provide a car hood to solve the above technical problems.

[0004] To this end, the present invention proposes a car hood, including a hood body, the hood body including a hood outer panel and a hood inner panel, a hood cavity being formed between the hood outer panel and the hood inner panel, the car hood also including a bracket mounting structure, the bracket mounting structure including: a supporting through hole, the supporting through hole being arranged on the hood inner panel; a bracket, the bracket including a bracket body, the bracket body being located in the hood cavity and mounted on the hood body, the bracket including a cantilever extending from the bracket body, the cantilever corresponding to the position of the supporting through hole.

[0005] According to the above technical concept, the present invention may further include any one or more of the following optional forms.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0025] In this specification, position terms such as "front", "rear", "left", "right", "up", "down", "inside" and "outside" are defined according to the positions when the car is in normal use.

[0026] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] In view of the conflicting requirements of the coating performance and crushing performance of the automobile hood on the inner plate of the automobile hood in the prior art, the present invention introduces supporting through holes on the inner plate of the hood and simultaneously arranges cantilevers corresponding to the positions of the supporting through holes in the hood cavity of the automobile hood to solve the above technical problems.

[0028] Reference Figures 1 to 5An automobile hood is shown as an example, specifically, configured as an automobile front hood, which includes a hood body 100 and a bracket mounting structure. The hood body 100 includes a hood outer panel 110 and a hood inner panel 120, the hood outer panel 110 covers the hood inner panel 120, and a hood cavity 130 is formed between the hood outer panel 110 and the hood inner panel 120. The bracket mounting structure includes a support through hole 122 and a bracket 200, wherein the support through hole 122 is provided on the hood inner panel 120, the bracket 200 includes a bracket body 220 and a cantilever 221, the bracket body 220 is located in the hood cavity 130 and is mounted on the hood body 100, for example, the bracket body 220 is mounted on the hood outer panel 110 and / or the hood inner panel 120, the cantilever 221 extends from the bracket body 220 and corresponds to the position of the support through hole 122, for example, in some embodiments, Figure 3 and Figure 4 As shown, in the hood cavity 130, the cantilever 221 at least partially blocks the support through hole 122. The bracket mounting structure is configured so that the painting support rod 300 passes through the support through hole 122 and abuts against the cantilever 221. It should be understood that the automobile hood can be configured as an automobile front cover or an automobile rear cover, such as an automobile engine cover or an automobile trunk cover. Figure 1 The present automobile hood (car hood) is also illustrated during the painting process. The automobile hood has a free end and a hinged end. The free end of the automobile hood (i.e., the front end of the automobile hood, or the rear end of the automobile hood) is lifted and rotated around the hinged end of the automobile hood (i.e., the rear end of the automobile hood, or the front end of the automobile hood) by a certain angle, and then supported by a painting support rod 300. The painting support rod 300 is shown in a dotted outline. The painting support rod 300 passes through the support through hole 122 and abuts against the cantilever 221, so that the painting process no longer has excessive strength requirements for the hood inner panel 120 (and this requirement is difficult to avoid with the existing painting process). In this way, it is only necessary to mainly consider whether the hood inner panel 120 meets other requirements such as the collapse performance, while the cantilever 221 is in a suspended state and is not connected to the hood inner panel 120. In this way, the introduction of the cantilever 221 will not increase or decrease the strength of the hood inner panel 120, and will not affect the collapse performance of the hood inner panel 120. In some embodiments, the cantilever 221 has a higher mechanical strength than the hood inner plate 120, for example, the cantilever 221 is made of steel and the hood inner plate 120 is made of aluminum. The high mechanical strength of the cantilever 221 makes it more stable after the painting support rod 300 abuts against it, and further reduces the shaking of the car hood during the painting process relative to the existing painting process. It should be understood that in some embodiments, the bracket body 220 and the cantilever 221 can be formed integrally. It should also be understood that the cantilever 221 can be plate-shaped and a cantilever plate, or rod-shaped and a cantilever rod, or other suitable shapes. It should also be understood that the bracket 200 and the support through hole 122 can be arranged at a position close to the free end of the car hood to increase the lever arm when the painting support rod 300 supports.

[0029] In practical applications, a coating support rod 300 with matching size can be selected according to the size of the supporting through hole 122, such as Figure 1 and Figure 2 In the exemplary embodiment, the outer diameter of the portion of the painting support rod 300 inserted into the support through hole 122 is preferably substantially equal to the diameter of the support through hole 122. In this way, after the painting support rod 300 passes through the support through hole 122 and abuts against the cantilever 221, the support through hole 122 limits the position between the painting support rod 300 and the hood body 100, reduces shaking, and makes the support have good stability. This is another advantage of the present invention over the prior art in which the painting support rod directly abuts against the inner plate of the hood. In some embodiments, the cantilever 221 is provided with a groove (not shown) that is recessed in a direction away from the support through hole 122. The painting support rod 300 can be inserted into the groove of the cantilever 221 after passing through the support through hole 122. The diameter of the inserted portion is preferably substantially equal to the diameter of the groove, which can enhance the stability of the abutment of the painting support rod 300 against the cantilever 221 and the stability of the support for the automobile hood.

[0030] In some embodiments, Figure 2 and Figure 4 As shown, the bracket mounting structure further includes a mounting portion 121, the mounting portion 121 is disposed on the cover inner plate 120, and the bracket body 220 is mounted on the mounting portion 121. Further, in some embodiments, as Figures 2 to 5 As shown, the bracket 200 includes a wing plate 222 bent and extended from the bracket body 220. The wing plate 222 is arranged away from the cantilever 221 and extends toward the hood outer panel 110 and then abuts the hood outer panel 110, so that the entire bracket body 220 contacts the hood outer panel 110 and the hood inner panel 120 respectively from top to bottom. In this way, after the painting support rod 300 abuts against the cantilever 221, the force can be transmitted to the hood outer panel 110 through the wing plate 222, thereby dispersing the force, and further avoiding the plastic deformation of the hood inner panel 120 toward the hood outer panel 110. In other embodiments, the free end of the wing plate 222 is bent and extended to form an abutting section 222A, and the abutting section 222A is close to and abuts the hood outer panel 110. The abutting section 222A increases the contact area between the wing plate 222 and the hood outer panel 110, and disperses the force transmitted to the hood outer panel 110 by the wing plate 222. In this way, the hood outer panel 110 not only shares the force applied by the painting support rod 300, but also disperses the shared force to prevent plastic deformation of the hood outer panel 110. It should be understood that in some embodiments, the bracket body 220 and the wing plate 222 can be formed integrally, or the bracket body 220, the cantilever 221 and the wing plate 222 can be formed integrally.

[0031] It is conceivable that, in some embodiments, the bracket 200 and the support through hole 122 can be arranged near the existing automobile hood lock bracket. Figures 2 to 4 As shown, the mounting portion 121 is provided with an insertion hole 121A, and the bracket 200 itself is configured as a car hood lock bracket, so that the bracket 200 includes a hood lock 210, and the hood lock 210 can be roughly U-shaped, and both ends of the hood lock 210 pass through the insertion hole 121A and are installed on the bracket body 220. The hood lock 210 extends out of the hood body 100. When in use, it plays a role in locking the car hood and preventing the car hood from opening automatically.

[0032] In some embodiments, Figure 1 As shown, the automobile hood has two bracket mounting structures, and during the painting process, it is supported by two painting support rods 300, which can increase stability and disperse the supporting force, further avoiding possible local plastic deformation of the hood inner plate 120. It should be understood that the automobile hood can have more than two bracket mounting structures, and during the painting process, it can be supported by a corresponding number of painting support rods 300.

[0033] It should be understood that the above description of the preferred embodiment is relatively detailed and cannot be regarded as limiting the scope of patent protection of the present invention. Under the enlightenment of the present invention, ordinary technicians in this field can also make substitutions or modifications without departing from the scope of protection of the claims of the present invention, which all fall within the scope of protection of the present invention. The scope of protection requested for the present invention shall be based on the attached claims.
