[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0031] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.
[0032] Please refer to Figures 1 to 3 , Figure 1 A schematic structural diagram of a water trough installation structure provided by an embodiment of the present invention; Figure 2 It is an axonometric view of the connection between the water trough clamping plate and the water trough body; Figure 3 It is a top view of the water trough clamping plate and the water trough body being clamped together.
[0033] In a specific embodiment, the water trough installation structure provided by the present invention is mainly composed of two parts: a front panel sheet metal 10 and a water trough 20 arranged on the front panel sheet metal, wherein the water trough 20 is further divided into a water trough body 21 and two water trough clips 22, the water trough body 21 is made of polypropylene material, and the water trough clips 22 are made of polyformaldehyde material, and the parts are formed by injection molding process respectively.
[0034] Compared with metal sheet metal parts, the weight of polypropylene material at the same thickness is about 1 / 6 of that of sheet metal material, and the polypropylene material can be injection molded, which can not only effectively reduce the weight of the water flow channel 20, but also significantly reduce the production cost.
[0035] The interior of the water trough body 21 has a water trough that gradually deepens from the middle to both sides, and the depth of the first water trough on one side of the water trough body is greater than the depth of the second water trough on the other side. The bottom of the first water trough is provided with a sheet rib structure 211 for forming a water flow path along the gradually deepening direction.
[0036] This embodiment makes full use of the advantage of the strong plasticity of plastics, and through finite element analysis, designs a sheet rib structure 211 inside the first water flow channel. With the help of the sheet rib structure 211, the water flow path can be optimized, and the water guiding and drainage function of the water flow channel 20 can be fully utilized without increasing the cross-sectional area of the water flow channel 20, making the drainage more effective.
[0037] Please refer to Figure 4 , Figure 5 , Figure 4 It is a partial exploded schematic diagram of the clamping connection between the water trough clamping plate and the water trough body; Figure 5 for Figure 3 AA view of the .
[0038] As shown in the figure, two water trough clamps 22 are clamped to the left and right sides of the rear edge of the water trough body 21 through a clamping structure. The water trough clamps 22 are made of polyoxymethylene (POM) material, which has high strength, hard texture, good fatigue resistance and thermal stability.
[0039] Specifically, this clamping structure is mainly composed of a plurality of clamping grooves 212 arranged on the rear edge of the water trough body 21 and a plurality of clamping hooks 221 arranged on the upper surface of the water trough clamping plate 22, wherein the clamping groove 212 is in a horizontal "T" shape, the left and right projections of the clamping hook 221 are in a vertical "T" shape and the front and rear projections are in a "Z" shape, and after the head of the clamping hook 221 enters the clamping groove 212 from bottom to top, it is clamped in the clamping groove 212 by sliding horizontally.
[0040] In the front and rear projections, the two reverse bending angles forming the "Z" shape of the hook are right angles or obtuse angles, and there is a first spacing groove 222 between adjacent hooks in the left and right direction. The root of each hook 221 has a second spacing groove 223 between the body in the front and rear direction.
[0041] Each hook 221 has a stopper 224 at its tail, and is engaged with the slot 212 via the stopper 224 ; or, the hook 221 at the rear end in the sliding direction has a stopper 224 at its tail, and is engaged with the slot 212 via the stopper 224 .
[0042] During assembly, the water trough clamping plate 22 is connected to the water trough body 21 by sliding, that is, the water trough clamping plate 22 is directly inserted into the water trough body 21, and the connection is firm and does not retreat after being inserted. This connection is simple and reliable, and there are no conventional screws and bolts fasteners, so the assembly is simple and the cost is low.
[0043] The traditional water trough is welded with the vehicle body, while the lightweight plastic water trough provided by the present invention needs to be assembled with the vehicle body in the automobile manufacturing assembly workshop. In order to solve the problem of how to install the plastic water trough 20 on the vehicle body, the present invention designs a clamping structure, which can clamp the plastic water trough 20 on the front panel 10 of the vehicle. The two do not need conventional fasteners such as welding and bolting to fasten them, which is very simple and effective.
[0044] Please continue to refer to Figure 6 , Figure 7 , Figure 6 It is a cross-sectional view of the front panel before it enters the elastic clamping space of the water flow channel; Figure 7 This is a cross-sectional view of the front panel after it enters the elastic snap-in space of the water trough.
[0045] The water trough clamp 22 is located on the left and right sides of the rear edge of the water trough body 21, and an elastic clamping space is formed between the water trough clamp 22 and the rear edge of the water trough body 21. The water trough 20 is installed on the front panel sheet metal 10 in a backward push-in manner. After the two are connected, the front edge of the front panel sheet metal 10 is clamped in the elastic clamping space.
[0046] Specifically, the portion of the water trough clamp 22 used to form the elastic clamping space is wavy, and its last wave crest 225 is higher than the other wave crests. The rear edge 213 of the water trough body 21 is bent or folded upward, and a clamping opening for the front enclosure sheet metal 10 to enter the elastic clamping space is formed between it and the last wave crest of the water trough clamp 22; the front enclosure sheet metal 10 has a wavy clamping portion 11 near the front edge, and after clamping, the front edge of the front enclosure sheet metal 10 is clamped and fixed by the other wave crests of the water trough clamp 22, and the wavy clamping portion 11 of the front enclosure sheet metal 10 coincides with the last wave crest 225 of the water trough clamp 22.
[0047] The rear edge of the water trough clamp 22 is in a downwardly inclined shape to form a guiding surface for the front panel sheet metal 10 to enter the elastic clamping space. The last wave peak of the water trough clamp 22 is higher than the plane part of the rear edge 213 of the water trough body 21, and lower than the highest part of the rear edge 213 of the water trough body 21 that bends or folds upward, so as to ensure that the water trough clamp 22 and the front panel sheet metal 10 can be smoothly clamped, reduce the difficulty of alignment, and improve production efficiency.
[0048] The slope of the front side of the last wave crest of the water trough clamping plate 22 is greater than the slope of the rear side thereof. In this way, the resistance of the front wall sheet metal 10 from being separated from the elastic clamping space can be increased, and after the water trough clamping plate 22 and the front wall sheet metal 10 are clamped together, the two can be effectively prevented from being separated.
[0049] In addition, after the water trough clamping plate 22 is plugged into the front wall sheet metal 10, the two sides and the middle of the plastic water trough body 21 can be further fixed to the front cabin cross beam using bolts 30, thereby further reinforcing the water trough 20. Although bolts 30 are used here, the water trough clamping plate 22 and the front wall sheet metal 10, as well as the water trough clamping plate 22 and the water trough body 21 are connected by clamping, and no bolts are used. Therefore, overall, the amount of bolts used is significantly reduced.
[0050] The above embodiments are only preferred solutions of the present invention, and are not limited thereto. On this basis, targeted adjustments can be made according to actual needs to obtain different implementation methods. For example, the water trough clamping plate 22 is made of metal, and the water trough clamping body 21 is made of plastic, or the water trough clamping plate 22 is clamped to the water trough body 21 in other ways, etc. Since there are many possible implementation methods, they will not be described one by one here.
[0051] In view of the problem that the existing sheet metal water flow channel has a large mass and high investment cost, the present invention provides a water flow channel 20 made of plastic material, which uses plastic as the main material of the water flow channel structure to achieve the purpose of lightweight and low investment cost, and can reduce weight by about 50%.
[0052] Moreover, in order to solve the installation problem of the plastic water flow trough, a card board connection structure is designed, which is not only simple in structure and easy to operate, but also reliable and effective in connection.
[0053] In addition to the above-mentioned water trough installation structure, the present invention also provides a car, which can be specifically a fuel car, a new energy car or a hybrid car, the front part of which is provided with a front windshield and a car water trough located below the front windshield, and the car water trough is provided with the water trough installation structure described above. Regarding the rest of the structure of the car, please refer to the prior art, which will not be repeated in this article.
[0054] The water trough installation structure and the automobile provided by the present invention are introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation method of the present invention. The description of the above embodiments is only used to help understand the core idea of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
