Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0049] The embodiments of the present application provide a design method of a front top storage box, a front top storage box and a vehicle, which can solve the problem of reducing the lightweight effect of the front top module in the prior art due to the existence of the framework cross beam, and the framework cross beam is generally large in size and made of iron, so the weight is relatively heavy, and the total weight generally accounts for about 1 / 3 of the entire front top storage box.

[0050] As shown in Figure 7 In the prior art, the storage box includes a box bucket assembly 1, a panel assembly 4, a bottom plate assembly 5 and a framework cross beam 6.

[0053] The reinforcing rib group 2 and / or the reinforcing support group 3 are set and adjusted in the target reinforcing area, and strength and modal analysis is performed on the reinforced box bucket assembly 1 until the strength and modal of the storage box meet the requirements.

[0054] In the design of the front-top storage box, the box hopper assembly 1 is subjected to strength analysis, and the strength analysis result of the box hopper assembly 1 with the skeleton cross beam is compared to obtain a target strengthening area, the reinforcing rib group 2 and / or the reinforcing support group 3 are arranged and adjusted in the target strengthening area, and the strengthened box hopper assembly 1 is subjected to strength and modal analysis until the strength and modal of the storage box meet the requirements. Since the design method of the front-top storage box can meet the strength and modal requirements, and the storage box does not have the skeleton cross beam 6, the weight of the storage box is reduced, the lightweight effect of the front-top module is improved, and the problem of reducing the lightweight effect of the front-top module due to the existence of the skeleton cross beam in the prior art is solved. The skeleton cross beam has a relatively large size and is made of iron, so the weight is relatively heavy, and the total weight generally accounts for about 1 / 3 of the total weight of the front-top storage box.

[0055] As shown in Figure 6 The design method of the front-top storage box designed by the storage box does not have the skeleton cross beam 6, and includes the box hopper assembly 1, the panel assembly 4, and the bottom plate assembly 5.

[0057] The reinforcing rib group 2 and / or the reinforcing support group 3 are arranged and adjusted in the target strengthening area, and the strengthened box hopper assembly 1 is subjected to strength analysis until the strength requirement is met;

[0058] The box hopper assembly 1 that meets the strength requirement is subjected to modal analysis, and the design parameters of the storage box are confirmed according to the result of the modal analysis, or the design parameters of the storage box are adjusted until the strength and modal requirements are met.

[0059] In the present embodiment, the reinforcing rib group 2 and / or the reinforcing support group 3 are arranged and adjusted in the target strengthening area, and the strengthened box hopper assembly 1 is subjected to strength and modal analysis until the strength and modal of the storage box meet the requirements, specifically including arranging and adjusting the reinforcing rib group 2 and / or the reinforcing support group 3 in the target strengthening area, and subjecting the strengthened box hopper assembly 1 to strength analysis until the strength requirement is met, subjecting the box hopper assembly 1 that meets the strength requirement to modal analysis, and confirming the design parameters of the storage box according to the result of the modal analysis, or adjusting the design parameters of the storage box until the strength and modal requirements are met. The strength analysis is performed first, and then the modal analysis is performed, which facilitates the adjustment of the parameters of the reinforcing rib group 2 and / or the reinforcing support group 3.

[0060] In some optional embodiments, the design parameters of the litter box are confirmed or adjusted according to the result of the modal analysis until the strength and modal requirements are met, including:

[0061] determining whether the modal frequency of the box hopper assembly 1 falls into the idling resonance frequency range of the litter box;

[0063] if the modal frequency falls into the idling resonance frequency range of the litter box, adjusting the design parameters of the litter box until the strength and modal requirements are met.

[0064] In the present embodiment, the design parameters of the litter box are confirmed or adjusted according to the result of the modal analysis until the strength and modal requirements are met, specifically including determining whether the modal frequency of the box hopper assembly 1 falls into the idling resonance frequency range of the litter box, if the modal frequency does not fall into the idling resonance frequency range of the litter box, confirming the design parameters of the litter box, and if the modal frequency falls into the idling resonance frequency range of the litter box, adjusting the design parameters of the litter box until the strength and modal requirements are met. The specific process of confirming or adjusting the design parameters of the litter box according to the result of the modal analysis is specifically explained, which facilitates the determination of the design parameters of the litter box and improves the design efficiency.

[0065] In some optional embodiments, when the modal frequency falls into the idling resonance frequency range of the litter box, the design parameters of the litter box are adjusted until the strength and modal requirements are met, including:

[0066] adjusting the parameters of the group of reinforcing ribs 2 and / or the group of reinforcing supports 3 and performing modal analysis until the modal requirements are met;

[0067] if the modal frequency of the adjusted litter box is greater than the idling resonance frequency range of the litter box, the design parameters of the litter box are confirmed;

[0069] In the embodiment, when the modal frequency falls into the idling resonance frequency interval of the litter box, the parameters of the group of reinforcing ribs 2 and / or the group of reinforcing supports 3 are adjusted, and modal analysis is performed until the modal requirement is met. If the modal frequency of the adjusted litter box is greater than the idling resonance frequency interval of the litter box, the design parameters of the litter box are confirmed. If the modal frequency of the adjusted litter box is less than the idling resonance frequency interval of the litter box, strength analysis is performed on the adjusted litter box, the design parameters of the litter box are confirmed according to the strength analysis result, or the design parameters of the litter box are adjusted until the strength and modal requirements are met, so that the design parameters of the litter box are conveniently determined, and the design efficiency is improved.

[0070] In the embodiment, the design parameters of the litter box include the parameters of the group of reinforcing ribs 2, the parameters of the group of reinforcing supports 3, and the parameters of the box-dip assembly 1.

[0073] If the strength requirement is not met, the parameters of the group of reinforcing ribs 2 and / or the group of reinforcing supports 3 are adjusted, and it is determined whether there is a balance point for the strength and modal of the box-dip assembly 1.

[0074] If there is a balance point, the parameters of the group of reinforcing ribs 2 and / or the group of reinforcing supports 3 are adjusted.

[0075] If there is no balance point, the parameters of the group of reinforcing ribs 2 and / or the group of reinforcing supports 3 and the parameters of the box-dip assembly 1 are adjusted.

[0076] In the embodiment, when the modal frequency of the adjusted litter box is less than the idling resonance frequency interval of the litter box, strength analysis is performed on the adjusted litter box. If the strength requirement is met, the design parameters of the litter box are confirmed. If the strength requirement is not met, the parameters of the group of reinforcing ribs 2 and / or the group of reinforcing supports 3 are adjusted, and it is determined whether there is a balance point for the strength and modal of the box-dip assembly 1. If there is a balance point, the parameters of the group of reinforcing ribs 2 and / or the group of reinforcing supports 3 are adjusted. If there is no balance point, the parameters of the group of reinforcing ribs 2 and / or the group of reinforcing supports 3 and the parameters of the box-dip assembly 1 are adjusted, so that the design parameters of the litter box are conveniently determined, and the design efficiency is improved.

[0077] In the embodiment, the parameters of the box-dip assembly 1 generally refer to the weight of the box-dip assembly 1.

[0078] In some optional embodiments, the arranging and adjusting of the reinforcing rib group 2 and / or the reinforcing support group 3 in the target reinforcing area includes: according to the actual installation space of the box and hopper assembly 1, dividing the target reinforcing area into a reinforcing rib group 2 installation area and a reinforcing support group 3 installation area.

[0079] In the embodiment, the arranging and adjusting of the reinforcing rib group 2 and / or the reinforcing support group 3 in the target reinforcing area specifically includes: according to the actual installation space of the box and hopper assembly 1, dividing the target reinforcing area into a reinforcing rib group 2 installation area and a reinforcing support group 3 installation area. Since the outer surface of the box and hopper assembly 1 is not a completely regular shape, some positions in the target reinforcing area are inconvenient for the installation of the reinforcing support group 3 on the outer surface, or some positions in the target reinforcing area cannot reach the designed strength through the reinforcing support group 3. At this time, the above-mentioned situation can be solved by installing the reinforcing rib group 2, and the design of the litter box is facilitated.

[0080] In some optional embodiments, the strength analysis of the box and hopper assembly 1 and the comparison with the strength analysis result of the box and hopper assembly 1 with the skeleton crossbeam to obtain the target reinforcing area include:

[0081] The strength of the box and hopper assembly 1 is analyzed by CAE to obtain the strength change direction of the box and hopper assembly 1;

[0082] According to the strength change direction of the box and hopper assembly 1, the installation position and installation direction of the reinforcing rib group 2 and / or the reinforcing support group 3 are obtained.

[0083] In the embodiment, the strength analysis of the box and hopper assembly 1 and the comparison with the strength analysis result of the box and hopper assembly 1 with the skeleton crossbeam to obtain the target reinforcing area specifically include: the strength of the box and hopper assembly 1 is analyzed by CAE to obtain the strength change direction of the box and hopper assembly 1; and according to the strength change direction of the box and hopper assembly 1, the installation position and installation direction of the reinforcing rib group 2 and / or the reinforcing support group 3 are obtained. The strength change direction of the box and hopper assembly 1 can be better matched, and the reinforcing effect is better.

[0084] As shown in Figure 1 , Figure 2 , Figure 6 , Figure 8 , Figure 9 and Figure 10 , in one aspect, the application also provides a front top litter box designed by using the above-mentioned design method of the front top litter box.

[0085] In the design of the front-top storage box, the strength of the box assembly 1 is analyzed, and the strength analysis result of the box assembly 1 with the skeleton beam is compared to obtain the target strengthening area. The reinforcing rib group 2 and / or the reinforcing support group 3 are set and adjusted in the target strengthening area, and the strength and modal analysis of the reinforced box assembly 1 is carried out until the strength and modal of the storage box meet the requirements. Since the design method of the front-top storage box can meet the strength and modal requirements, and the storage box does not have a skeleton beam 6, the weight of the storage box is reduced, the lightweight effect of the front-top module is improved, and the problem of reducing the lightweight effect of the front-top module due to the existence of the skeleton beam in the prior art is solved. The size of the skeleton beam is generally large, and the material is iron, so the weight is heavy, and the total weight generally accounts for about 1 / 3 of the entire front-top storage box.

The first reinforcing support group 31 includes a plurality of first reinforcing supports 311 arranged along the upper side edge of the box assembly 1, and the second reinforcing support group 32 includes a plurality of reinforcing units arranged along the length direction of the box assembly 1. The reinforcing unit includes a plurality of second reinforcing supports 321 arranged along the thickness direction of the box assembly 1, which has a simple structure and good reinforcing effect.

[0090] In the present embodiment, the shapes of the first reinforcing support 311 and the second reinforcing support 321 are matched with the parts arranged on the box assembly 1, and are matched with the structure strength weakening direction of the box assembly 1.

[0091] As shown in Figure 2 and Figure 5 , in the present embodiment, the reinforcing rib group 2 includes a plurality of reinforcing rib units 21, and the plurality of reinforcing rib units 21 are arranged along the edge of the box assembly 1.

[0092] In the present example, the first reinforcing support group 31 includes ten first reinforcing supports 311, four of which are arranged on the middle protrusion of the box assembly 1 and can be connected with the connecting beam to be connected to the vehicle body, and the remaining six first reinforcing supports 311 are evenly distributed on both sides of the middle protrusion.

[0094] In the design of the front top glove box, the box assembly 1 is subjected to strength analysis, and the strength analysis result of the box assembly 1 with the skeleton beam is compared to obtain the target reinforcing area. The reinforcing rib group 2 and / or the reinforcing support group 3 are arranged and adjusted in the target reinforcing area, and the strength and modal analysis of the reinforced box assembly 1 is carried out until the strength and modal of the glove box meet the requirements. Since the glove box designed by the design method of the front top glove box can meet the strength and modal requirements, and the glove box does not have the skeleton beam 6, the weight of the glove box is reduced, the lightweight effect of the front top module is improved, and the problem of reducing the lightweight effect of the front top module due to the existence of the skeleton beam in the prior art is solved. The size of the skeleton beam is generally large, and the material is iron, so the weight is heavy, and the total weight generally accounts for about 1 / 3 of the entire front top glove box.
