[0030] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.
[0031] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.
[0032] Combined with Figure 1 and attached Figure 2 The support device of the vehicle hood proposed by the utility model includes a first support portion 10, a second support portion 20 and a mounting portion 30. The first support portion 10 is connected to the second support portion 20 in the up-down direction. The upper end of the first support portion 10 contacts the hood. The first support portion 10 is configured to move downward relative to the second support portion 20 under the action of an external force, so that the hood forms a crushing area at the force-bearing position. The lower end of the second support portion 20 contacts the body sheet metal 40. The lower end of the second support portion 20 is connected to the mounting portion 30. The mounting portion 30 is used to install the first support portion 10 and the second support portion 20 on the body sheet metal 40. A mounting hole 41 that cooperates with the mounting portion 30 is opened on the body sheet metal 40. The circumferential dimension of at least the lower portion of the first support portion 10 is less than or equal to the circumferential dimension of the mounting hole 41, and the circumferential dimension of the second support portion 20 is greater than the circumferential dimension of the mounting hole 41. When the first support portion 10 moves downward relative to the second support portion 20, the first support portion 10 can be at least partially accommodated in the mounting hole 41, so that the hood forms a larger crushing area.
[0033] When the vehicle is in a safe state, the first support portion 10 and the second support portion 20 cooperate to support the hood to ensure the structural strength of the hood; when the vehicle collides with a pedestrian, the hood is subjected to external force and the force is transmitted to the first support portion 10, causing the first support portion 10 to move downward relative to the second support portion 20. The supporting effect of the first support portion 10 on the hood becomes invalid, and the hood sinks to form a crushed area, which can minimize the damage to pedestrians caused by the hood, thereby protecting pedestrians and enabling the vehicle to have good pedestrian protection performance.
[0034] Combined with Figure 2 and attached Figure 3 The first support portion 10 includes a main body 11, and the main body 11 includes a cavity 111. The cavity 111 runs through the lower end of the main body 11. The setting of the cavity 111 can reduce the weight of the main body 11, and compared with the solid main body 11, the cavity 111 can reduce the structural strength of the main body 11, so that the first support portion 10 can more easily produce a downward crushing movement relative to the second support portion 20.
[0035] Exemplarily, the main body 11 is a columnar structure, more specifically, the main body 11 is a cylindrical structure, and of course it can also be set to other shapes, such as a prism, a truncated cone, etc. This example should not be understood as a limitation on the main body 11.
[0036] Exemplarily, the radial dimension of the main body 11 is less than or equal to the radial dimension of the mounting hole 41, and the circumferential dimension of the main body 11 is less than or equal to the circumferential dimension of the mounting hole 41. With such a configuration, when the main body 11 moves downward under external force, it can sink into the mounting hole 41 to ensure the crushing effect.
[0037] In one embodiment, in combination with Figure 2 and attached Figure 3 The first support portion 10 also includes a first reinforcement 12, which is located in the cavity 111 and connected to the upper cavity wall of the cavity 111. The first reinforcement 12 is used to increase the strength of the upper end of the main body 11 so that the main body 11 has good supporting force for the hood and can ensure the structural strength of the hood.
[0038] Exemplarily, the first reinforcement member 12 is formed integrally with the main body 11 .
[0039] Exemplarily, the first reinforcement 12 is configured as a columnar structure. More specifically, the first reinforcement 12 is a cylindrical structure. Of course, it can also be configured as other shapes, such as a prism, a truncated cone, etc. This example should not be understood as a limitation on the first reinforcement 12.
[0040] Exemplarily, the first reinforcement 12 is a hollow structure, that is, the orthographic projection of the first reinforcement 12 along the up-down direction is annular. Such a configuration can reduce the overall weight of the first support portion 10, which is beneficial to the lightweight design of the vehicle.
[0041] Exemplarily, the first reinforcement member 12 is coaxially connected to the main body 11 .
[0042] In one embodiment, in combination with Figure 2 and attached Figure 3 The first support portion 10 also includes a second reinforcement 13, which is located in the cavity 111. The second reinforcement 13 is used to connect the outer wall of the first reinforcement 12 and the side wall of the cavity 111. The second reinforcement 13 can increase the stability of the first reinforcement 12 and ensure that the first reinforcement 12 does not fall off in the cavity 111, thereby ensuring the supporting effect of the first support portion 10 on the hood, so that the hood has good structural strength.
[0043] For example, as shown in the attached Figure 2 As shown, the upper end of the second reinforcement 13 is connected to the upper wall of the cavity 111. Such an arrangement can increase the structural strength of the upper end of the main body 11 and ensure the supporting effect of the first support portion 10 on the hood.
[0044] Exemplarily, at least one second reinforcement 13 is provided. When the number of second reinforcements 13 is greater than two, the second reinforcements 13 are distributed along the circumference of the first reinforcement 12 . Such a configuration can improve the stability and reliability of the circumferential connection between the first reinforcement 12 and the main body 11 .
[0045] Exemplarily, the second reinforcement member 13 is integrally formed with the main body 11 and the first reinforcement member 12 .
[0046] Exemplarily, for ease of understanding, the side where the second reinforcement 13 is connected to the side wall of the cavity 111 is called the first connection end, and the side where the second reinforcement 13 is connected to the outer side wall of the first reinforcement 12 is called the second connection end. The length dimension of the first connection end along the up and down direction is greater than the dimension of the second connection end along the up and down direction. Such a setting can ensure the connection stability of the second reinforcement 13 and can effectively improve the strength of the main body 11, so that the first support portion 10 has sufficient supporting force for the hood.
[0047] In one embodiment, in combination with Figure 2 and attached Figure 3The first support portion 10 also includes a guide member 14, which is protruding from the lower end of the main body 11. The guide member 14 extends in the up-down direction and protrudes toward the side close to the mounting portion 30. When the first support portion 10 and the second support portion 20 are mounted on the body sheet metal 40 through the mounting portion 30, the guide member 14 is accommodated in the mounting hole 41. When the first support portion 10 moves downward relative to the second support portion 20 under the action of external force, the guide member 14 can make the main body 11 fall stably in the up-down direction, thereby ensuring the crushing effect of the hood.
[0048] Exemplarily, the guide member 14 is formed integrally with the main body 11 .
[0049] Combined with Figure 2 To Attachment Figure 4 The second supporting portion 20 includes a base member 21, the upper end of the base member 21 is connected to the lower end of the main body 11, a through hole 211 is provided on the base member 21 to cooperate with the main body 11, the radial dimension of the base member 21 is greater than the radial dimension of the mounting hole 41 on the body sheet metal 40, the radial dimension of the through hole 211 is greater than the radial dimension of the main body 11, a connecting rib 212 is convexly provided on the side wall of the through hole 211, one end of the connecting rib 212 is connected to the side wall of the main body 11, when the second supporting portion 20 is mounted on the body sheet metal 40 through the mounting portion 30, the base member 21 will not fall out of the mounting hole 41, the second supporting portion 20 can support the collapsed hood, when the hood is subjected to external force, the connecting rib 212 is easily broken, so that the main body 11 can move downward relative to the base member 21.
[0050] Exemplarily, the base member 21 is coaxially connected to the main body 11 .
[0051] Exemplarily, the base member 21 is configured as a columnar structure. More specifically, the base member 21 is a cylindrical structure. Of course, it can also be configured as other shapes, such as a prism, a truncated cone, etc. This example should not be understood as a limitation on the base member 21.
[0052] Exemplarily, the connecting ribs 212 extend in the radial direction of the base member 21 . When a plurality of connecting ribs 212 are provided, the plurality of connecting ribs 212 are spaced apart and distributed along the circumference of the main body 11 .
[0053] In one embodiment, in combination with Figure 3 and attached Figure 4 A contact piece 213 is protruding from the lower end of the base member 21. When the second support portion 20 is mounted on the body sheet metal 40 through the mounting portion 30, the lower end of the contact piece 213 contacts the body sheet metal 40, and the mounting portion 30 is connected to the contact piece 213. The provision of the contact piece 213 can increase the thickness dimension of the base member 21 in the up and down directions, so that the connection of the mounting portion 30 is stable.
[0054] Exemplarily, the contact member 213 is integrally formed with the base member 21 .
[0055] For example, as shown in the attached Figure 3 As shown, the contact member 213 extends radially along the base member 21 , and one end of the contact member 213 close to the through hole 212 does not extend beyond the through hole 212 , that is, the orthographic projection of the contact member 213 along the vertical direction does not overlap with the orthographic projection of the through hole 212 along the vertical direction.
[0056] Exemplarily, at least one contact member 213 is provided.
[0057] As attached Figure 6 As shown, the mounting portion 30 includes a movable part 31 and a clamping part 32. One end of the movable part 31 is connected to the lower end of the base member 21, and the other end of the movable part 31 is a free end. The clamping part 32 is connected to the free end of the movable part 31, and the clamping part 32 extends radially. The free end of the movable part 31 is configured to be movable radially relative to the base member 21, so that the mounting portion 30 can enter the mounting hole 41 and be clamped in the mounting hole 41.
[0058] In one embodiment, in combination with Figure 3 and attached Figure 6 One end of the movable part 31 is connected to the lower end of the base part 21 and the contact part 213. The contact part 213 is located on both sides of the movable part 31, that is, the movable part 31 is sandwiched between the two contact parts 213. Such a configuration can increase the contact area between the movable part 31 and the base part 21, improve the stability of the movable part 31, and the contact part 213 can limit the movement direction of the movable part 31 to ensure the installation and fixing effect of the mounting part 30.
[0059] Exemplarily, the movable member 31 and the clamping member 32 are integrally formed.
[0060] As attached Figure 5 As shown, a functional groove 214 is provided on the base member 21, and the orthographic projection of the clamp 32 along the up-down direction is located within the orthographic projection area of the functional groove 214 along the up-down direction. The setting of the functional groove 214 can weaken the structural strength of the connection between the base member 21 and the mounting portion 30, so that the movable member 31 can easily generate radial movement, which is convenient for connecting the mounting portion 30 with the body sheet metal 40, and the functional groove 214 can reduce the overall weight of the base member 21, which is beneficial to the lightweight design of the vehicle.
[0061] Illustratively, the functional groove 214 penetrates the base member 21 in the up-down direction.
[0062] Exemplarily, four mounting portions 30 are provided, and four functional grooves 214 are provided, and are distributed on the base member 21 along the circumferential direction.
[0063] Combined with Figure 3 and attached Figure 6The mounting portion 30 further includes a clamping rib 33, which is protruding from the lower end of the base member 21 and located at the radially outer side of the guide member 14. The position of the clamping rib 33 is matched with the mounting hole 41. When the mounting portion 30 is connected to the mounting hole 41, the outer end surface of the clamping rib 33 contacts the hole wall of the mounting hole 41. The setting of the clamping rib 33 can play a role in rapid positioning and installation, ensuring one-time installation in place, and can ensure that the first support portion 10 and the second support portion 20 are centrally installed in the mounting hole 41, thereby ensuring the crushing effect of the first support portion 10.
[0064] By designing the mounting portion 30 and the first supporting portion 10 in a zoned manner, it is possible to avoid the first supporting portion 10 from affecting the mounting effect of the mounting portion 30 when it is crushed by force, and to prevent the mounting portion 30 from deforming and causing installation failure, thereby ensuring the modality of the hood.
[0065] By adopting the support device of the vehicle hood of the utility model, the first support part 10 is in contact with the hood, and can support the hood to ensure the structural strength of the hood; the second support part 20 can be in contact with the body sheet metal 40 to ensure the structural stability of the first support part 10; the mounting part 30 can mount the first support part 10 and the second support part 20 on the body sheet metal 40, and the first support part 10 is configured to be able to move downward relative to the second support part 20. When the hood is subjected to external force, the first support part 10 can move downward to form a crushed area on the hood, which effectively reduces the degree of injury to pedestrians in a collision accident and improves the safety performance of the entire vehicle. The structure is simple and has good practicality.
[0066] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0067] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
