[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0031] The water retaining assembly, vehicle tailgate and vehicle in the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the prior art, after the tailgate of a vehicle is opened, liquids such as rainwater or cleaning fluid will flow on their own under the action of gravity, and the direction of the liquid flow cannot be controlled. Some of the liquid will flow into the interior of the trunk, affecting its use.

[0033] In order to solve the above technical problems, an embodiment of the present application provides a water retaining assembly, including a base and a water retaining member, the base is provided with a through groove; two water retaining members are provided, and are fixed at the opposite ends of the through groove through a connecting structure, and the through groove and the two water retaining members cooperate to enclose an accommodating space; wherein, the base has an abutting surface facing the water retaining member; the water retaining member includes a main body and a water retaining member, the water retaining member is arranged on the side of the main body, and a portion of the surface of the water retaining member away from the main body and close to the abutting surface is pressed against the abutting surface. By arranging water retaining parts at the opposite ends of the through groove, the through groove and the two water retaining parts cooperate to form an accommodating space, in which the liquid can be retained and will not flow arbitrarily due to gravity; the water retaining parts are fixed at the two ends of the through groove through a connecting structure, so that the water retaining part abuts against the abutting surface, and the two are tightly overlapped, thereby preventing the liquid from flowing out from between the water retaining part and the abutting surface; in addition, the surface of the water retaining part away from the main body and close to the abutting surface is pressed against the abutting surface, that is, the side surface of the water retaining part in the thickness direction abuts against the abutting surface. With such an arrangement, the water retaining part will have a larger contact area with the abutting surface, and the fit between the water retaining part and the abutting surface will be better. This will be explained in detail below.

[0034] See Figure 1 、 Figure 2 and Figure 6 In one embodiment, the water retaining assembly includes a base 10 and a water retaining member 20. A through groove 11 is provided on the base 10. The water retaining member 20 is fixedly arranged at the opposite ends of the through groove 11 through a connecting structure. The two water retaining members 20 and the through groove 11 together form a accommodating space 30. The liquid can be temporarily stored in the accommodating space 30. When the liquid flows disorderly under the action of gravity, it will not flow out of the accommodating space 30, thereby preventing the liquid from affecting the area outside the accommodating space 30.

[0035] For ease of explanation, the base 10 involved in the following embodiments is a vehicle tailgate. In some embodiments, it can also be set in other forms, but not limited to this; a through groove 11 is provided on the vehicle tailgate, which can be used for the installation of components such as car lights. When the vehicle tailgate (base 10) is in a closed state, the opening of the accommodating space 30 (the opening opposite to the bottom of the through groove 11, the same below) faces the rear side (i.e., the rear side of the vehicle). When the vehicle tailgate is opened, the opening of the accommodating space 30 faces upward (i.e., above the vehicle), and the liquid will gather in the accommodating space 30 under the action of gravity. If the water barrier 20 is not provided, the liquid will flow from the through groove 11 to the inside of the trunk.

[0036] In some embodiments, the through slot 11 is not only Figure 1 The horizontal setting shown is determined by the design of the tailgate and is not limited to this.

[0037] In this embodiment, the base 10 (vehicle tailgate) has an abutment surface 12 facing the water retaining member 20, and the water retaining member 20 includes a main body 21 and a water retaining portion 22. The water retaining portion 22 is arranged on the side of the main body 21, and the end of the water retaining portion 22 away from the main body 21 abuts on the abutment surface 12. Through the setting of the connecting structure, the water retaining portion 22 is closely fitted with the abutment surface 12, thereby preventing the liquid flowing into the accommodating space 30 from flowing out from between the water retaining portion 22 and the abutment surface 12; at the same time, the surface of the water retaining portion 22 away from the main body 21 and close to the abutment surface 12 is pressed against the abutment surface 12 (such as Figure 6 As shown), that is, after the water retaining member 20 is fixed to both ends of the through groove 11 through the connecting structure, the side surface of the water retaining portion 22 in the thickness direction (as shown Figure 6 As shown, the surface where the water retaining portion 22 contacts the abutting surface 12 (the same below) abuts against the abutting surface 12. Such an arrangement can effectively increase the contact area between the water retaining portion 22 and the abutting surface 12, and the fit between the water retaining portion 22 and the abutting surface 12 will be better, further preventing the liquid flowing into the accommodating space 30 from flowing out from between the water retaining portion 22 and the abutting surface 12.

[0038] It should be noted that the abutting surface 12 is the transverse direction of the through groove 11 ( Figure 1 The plane around the opening (viewing angle) abuts against the water retaining portion 22, thereby preventing liquid from flowing out from between the water retaining portion 22 and the abutting surface 12; the shape of the abutting surface 12 is determined according to the specific design of the base 10, and the water retaining portion 22 is adapted to the abutting surface 12 accordingly.

[0039] See Figure 3 In one embodiment, the water retaining portion 22 has a plurality of elastic sub-portions 221 and a connecting sub-portion 222 connected between two adjacent elastic sub-portions 221. In this embodiment, four elastic sub-portions 221 are provided; when the water retaining member 20 is installed through the connecting structure, the elastic sub-portion 221 is pressed onto the abutting surface 12, and a force toward the abutting surface 12 is applied to the abutting surface 12, that is, the elastic sub-portion 221 is deformed under pressure, and under the action of the elasticity of the elastic sub-portion 221 itself, the elastic sub-portion 221 fits more closely to the abutting surface 12, thereby improving the water retaining performance; when the water retaining member 20 is installed through the connecting structure, the connecting sub-portion 222 is just fitted onto the corresponding abutting surface 12, that is, no interaction force is generated between the connecting sub-portion 222 and the abutting surface 12. With such arrangement, after the connecting sub-portion 222 is fitted against the abutting surface 12, no wrinkles (i.e. no gaps) will be generated at the junction between the connecting sub-portion 222 and the elastic sub-portion 221; when the connecting sub-portion 222 is the same as the elastic sub-portion 221 (there is an interactive abutting pressure between the connecting sub-portion 222 and the abutting surface 12), wrinkles (gaps) will easily be generated at the junction between the connecting sub-portion 222 and the elastic sub-portion 221, and liquid will flow out from the wrinkles.

[0040] For the sake of convenience, in this embodiment, the connecting structure includes a connecting seat 50 and a connecting head adapted to the connecting seat 50. The connecting seat 50 is arranged on the surface of the main body 21 facing the through groove 11, and the connecting head is arranged on the end surface of the headlight arranged in the through groove 11 facing the main body 21 (given in the figure). When installing the water retaining member 20, it is only necessary to move the water retaining member 20 along the length direction of the through groove 11. Specifically, the water retaining member 20 is moved toward the headlight in the through groove 11. During the movement, the end of the elastic sub-portion 221 away from the main body 21 contacts the corresponding abutment surface 12. Continue to move the water-blocking member 20. At this time, the elastic sub-portion 221 is deformed by the pressure. The elastic sub-portion 221 fits tightly with the abutment surface 12. The side surface of the elastic sub-portion 221 in the thickness direction contacts with the abutment surface 12, which increases the contact area and effectively improves the water-blocking performance. Continue to move the water-blocking member 20 until the connector is plugged into the connecting seat 50. At this time, the position of the water-blocking member 20 is fixed, and the connecting sub-portion 222 contacts with the corresponding abutment surface 12. The abutment surface 12 does not apply force to the connecting sub-portion 222 to deform it, that is, no wrinkles will be generated at the junction of the connecting sub-portion 222 and the elastic sub-portion 221.

[0041] In some embodiments, the relative position between the water retaining member 20 and the base 10 can be adjusted by controlling the height of the connecting seat 50, thereby achieving control over the deformation of the elastic sub-portion 221; in other embodiments, the arrangement positions of the connecting head and the connecting seat 50 can also be other forms of settings, for example, the connecting seat 50 is set on the main body 21, and the connecting head is set on the base 10, but it is not limited to this and is designed according to actual installation requirements.

[0042] See Figure 6In one embodiment, the water retaining portion 22 has an abutting sub-portion 223, a transition sub-portion 224 and a fixed sub-portion 225, the transition sub-portion 224 is connected between the abutting sub-portion 223 and the fixed sub-portion 225, the fixed sub-portion 225 is fixed to the main body 21 through the fixing structure 40, and the abutting sub-portion 223 abuts on the abutting surface 12 to form a barrier to the liquid; the width of the abutting portion between the abutting sub-portion 223 and the abutting surface 12 is W mm, satisfying: 2≤W≤10, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc.; when the value of W is less than 2, the contact area between the abutting sub-portion 223 and the abutting surface 12 is too small, the water retaining performance is poor, and the liquid in the accommodating space 30 is easy to flow from the abutting sub-portion 223 and the abutting surface 12; when the value of W is greater than 10, the part of the abutting sub-portion 223 close to the transition sub-portion 224 is more tightly fitted with the abutting surface 12 under the action of the transition sub-portion 224. On the contrary, the end of the abutting sub-portion 223 away from the transition sub-portion 224 becomes looser with the increase of W due to the excessive value of W, and the water-blocking performance is poor, which wastes production materials and increases production costs. Moreover, too large a W is not conducive to the arrangement and connection of other components. It has been verified that when 2≤W≤10, it can not only ensure the close fit between the abutting sub-portion 223 and the abutting surface 12 and improve the water-blocking performance, but also avoid the waste of production materials and reduce production costs.

[0043] See Figure 6 In one embodiment, the transition sub-portion 224 is arranged in an arc shape, and the fillet radius of the transition sub-portion 224 is R mm, which satisfies: 5≤R≤20, for example, 5, 10, 15, 20, etc.; the arc-shaped transition sub-portion 224 is conducive to the deformation of the abutting sub-portion 223 after contact with the abutting surface 12, that is, it is conducive to the close fit between the abutting sub-portion 223 and the abutting surface 12; when the value of R is less than 5, the arc length of the transition sub-portion 224 is short, and the transition between the fixed sub-portion 225 and the abutting sub-portion 223 is not smooth, which is not conducive to the direct fit between the abutting sub-portion 223 and the abutting surface 12, and the abutting sub-portion 223 and the abutting surface 12 are not close. When the abutting surface 12 is in contact, the abutting sub-portion 223 exerts a greater force on the abutting surface 12, that is, the reaction force of the abutting surface 12 on the abutting sub-portion 223 is greater. In some embodiments, the connecting head is easy to pop out from the connecting seat 50, which is not conducive to the stability of the structure; when the value of R is greater than 20, the material required for processing the water retaining portion 22 increases, which increases the production cost; it has been verified that when 5≤R≤20, the transition between the fixed sub-portion 225 and the abutting sub-portion 223 is smooth, which can not only ensure a better fit between the abutting sub-portion 223 and the abutting surface 12, improve the water retaining performance, but also save production raw materials and reduce production costs.

[0044] See Figure 6In one embodiment, the minimum thickness of the abutting sub-portion 223 is h1 mm, satisfying: 1≤h1≤1.5, for example, 1, 1.2, 1.3, 1.5, etc. When the value of h1 is less than 1, the abutting sub-portion 223 is too thin, which is not conducive to the tight fit between the abutting sub-portion 223 and the abutting surface 12, and is prone to water leakage; when the value of h1 is greater than 1.5, the abutting sub-portion 223 is too thick, and a greater force is required to abut the abutting sub-portion 223 against the abutting surface 12 to overcome the elastic force generated by the deformation of the abutting sub-portion 223 itself. In some embodiments, the connecting head is easy to pop out of the connecting seat 50, which is not conducive to the stability of the structure; it has been verified that when 1≤h1≤1.5, it can not only ensure that the abutting sub-portion 223 is better deformed to fit closely with the abutting surface 12, but also avoid excessive elastic force when the abutting sub-portion 223 is deformed.

[0045] See Figure 6 In one embodiment, the maximum thickness of the transition sub-portion 224 is h2 mm, satisfying: 2≤h2≤3, for example, 2, 2.5, 3, etc.; when the value of h2 is less than 2, the transition sub-portion 224 is too thin, and the support for the abutting sub-portion 223 is insufficient (the abutting sub-portion 223 cannot be pressed well on the abutting surface 12); when the value of h2 is greater than 3, production materials are wasted and production costs are increased; it has been verified that when 2≤h2≤3, it can not only ensure the support for the abutting sub-portion 223, but also save production costs.

[0046] See Figure 4 and Figure 5 In one embodiment, the fixing structure 40 includes spaced apart fixing holes 41 and fixing protrusions 42 adapted to fit within the fixing holes 41. In this embodiment, the fixing holes 41 are provided on the main body 21, and the fixing protrusions 42 are provided on the water retaining portion 22, resulting in a simple structure and a reliable connection. In some embodiments, the contact surfaces of the main body 21 and the water retaining portion 22 may be bonded by applying glue, but this is not limited to this embodiment.

[0047] On the other hand, the present application also relates to a vehicle tailgate, comprising any one of the aforementioned water retaining assemblies.

[0048] On the other hand, the present application also relates to a vehicle comprising the aforementioned vehicle tailgate.

[0049] The technical solution provided in the embodiment of the present application is intended to provide water retaining parts 20 at the opposite ends of the through groove 11, so that the through groove 11 and the two water retaining parts 20 cooperate to form an accommodating space 30, and the liquid can be retained in the accommodating space 30 and will not flow freely due to gravity; the water retaining parts 20 are fixed at the two ends of the through groove 11 through a connecting structure, so that the water retaining part 22 abuts on the abutting surface 12, and the two are tightly overlapped, thereby preventing the liquid from flowing out from between the water retaining part 22 and the abutting surface 12; in addition, the part of the surface of the water retaining part 22 away from the main body 21 and close to the abutting surface 12 is pressed against the abutting surface 12, that is, the side surface of the water retaining part 22 in the thickness direction abuts against the abutting surface 12. If the water retaining part 22 is arranged in this way, there will be a larger contact area with the abutting surface 12, and the fit between the water retaining part 22 and the abutting surface 12 will be better.
