[0028] As people's living standards continue to improve, self-driving tours are becoming an increasingly popular choice, and the versatility of a vehicle's functions to meet travel convenience is an important factor in people's selection. For example, for those who need to be flexible with their meals during their trip, they often store some kitchen utensils in their vehicles. People utilize the tailgate of vehicles to create storage structures; however, kitchen utensils require a high level of cleanliness, and these storage structures need to be cleaned regularly.

[0029] The existing containment structure has rotating baffles to facilitate the loading and unloading of items, but when flushing, sewage leaks from all sides of the baffles, polluting the surrounding environment and causing problems.

[0030] In view of this, this application provides a tailgate to solve the above problems. By providing a mounting part protruding in the receiving cavity of the tailgate body for fixed installation with a baffle, the mounting part, the baffle and the bottom wall of the cavity form a mounting groove, which is convenient for placing kitchen utensils in the tailgate body. In order to facilitate rinsing the mounting groove and prevent the cleaning liquid from leaking everywhere, a drainage channel is provided on the mounting part so that the cleaning liquid can be discharged from the drainage channel.

[0031] like Figure 1 and Figure 2This application provides a tailgate, including a tailgate body 100, a baffle 200, and a sealing element 300. The tailgate body 100 includes a receiving cavity 101 and an opening 102 located at one end of the receiving cavity 101. The tailgate body 100 includes a mounting portion 130 received in the receiving cavity 101 and a cavity bottom wall 110 opposite to the opening 102. The mounting portion 130 protrudes from the cavity bottom wall 110 in the direction of the opening 102. The tailgate body 100 has a drainage channel 120 that passes through the mounting portion 130 and connects the receiving cavity 101 to the outside. The baffle 200 is received in the receiving cavity 101 and installed on the side of the mounting portion 130 away from the receiving cavity 101. At least a portion of the baffle 200 is opposite to the cavity bottom wall 110.

[0032] The tailgate body 100, as the core load-bearing structure of the vehicle tailgate, is fixedly installed on the rear body frame of the vehicle. In some examples, the tailgate body 100 may be made of aluminum alloy, high-strength steel plate, or carbon fiber composite material. In some examples, the tailgate body 100 may be curved, flat, or similar shapes.

[0033] The receiving cavity 101 on the tailgate body 100 is the core space for forming the mounting groove. In some examples, the shape of the receiving cavity 101 can be a cuboid, a semi-cylinder, or an irregular polygon. The volume of the receiving cavity 101 can be adjusted according to the size of common kitchen utensils to ensure that it can accommodate items such as tableware.

[0034] In some examples, the shape of the opening 102 at one end of the receiving cavity 101 can be adapted to the cross-sectional shape of the receiving cavity 101, and can be rectangular, circular or oblong.

[0035] In some examples, the orthographic projection of the opening 102 lies within the orthographic projection of the cavity bottom wall 110 along the thickness direction of the tailgate body 100. As an example, the edges of the opening 102 may be chamfered to prevent sharp edges from scratching users or items.

[0036] For example, the material of the mounting part 130 may be the same as that of the tailgate body 100, or a higher strength material such as stainless steel may be selected to ensure stable bearing of the installation pressure of the baffle 200. In some examples, the shape of the mounting part 130 may be strip-shaped, block-shaped, or frame-shaped.

[0037] In some examples, the mounting portion 130 can be strip-shaped, U-shaped, or L-shaped. As an example, the surface of the mounting portion 130 away from the cavity bottom wall 110 is a flat surface.

[0038] In some examples, the mounting part 130 may be integrally formed with or separately connected to the tailgate body 100, wherein the number of mounting parts 130 is one or more.

[0039] In one example, the protrusion height of the mounting portion 130 is equal to or less than the depth of the receiving cavity 101. Exemplarily, the mounting portion 130 is located in an area that can connect to or is close to the cavity sidewall 140.

[0040] The bottom wall 110 serves as the bottom structure of the receiving cavity 101, and is made of the same material as the tailgate body 100. In some examples, the bottom wall 110 may be flat, curved, or have reinforcing ribs. Exemplarily, the bottom wall 110 may be a planar surface or a wall structure with irregularities.

[0041] For example, the cross-sectional shape of the drainage channel 120 may be semi-circular, circular, square, or trapezoidal. In some examples, there may be one or more drainage channels 120, and the dimensions of the multiple drainage channels 120 may be the same or different. As an example, when the tailgate is in the vertical position, the drainage channel 120 is located at the bottom to facilitate drainage.

[0042] The baffle 200 is connected to the mounting part 130 to enclose and form a storage compartment for storing kitchen utensils, etc. In some examples, the baffle 200 may be made of aluminum alloy, engineering plastic, or tempered glass. In some examples, the baffle 200 may be flat, curved, or have a flanged shape.

[0043] In some examples, the connection between the baffle 200 and the mounting portion 130 may be by bolting, welding, snap-fitting, or bonding. In some examples, the connection between the seal 300 and the baffle 200 and the mounting portion 130 may be by bonding, snap-fitting, or crimping.

[0044] By providing a mounting portion 130 protruding from the bottom wall 110 of the cavity 101 within the tailgate body 100, at least a portion of the baffle 200 is opposite to the bottom wall 110, thereby forming a storage slot with a groove by the mounting portion 130, the baffle 200, and the bottom wall 110. This storage slot provides a stable place for kitchen utensils, meeting the needs of users using kitchen utensils outdoors. The protruding structure of the mounting portion 130 ensures the volume of the mounting slot and provides a reliable mounting base for the baffle 200, improving the stability of the baffle 200. The drainage channel 120 passes through the mounting portion 130 and connects the cavity 101 to the outside, allowing the cleaning fluid to drain smoothly when cleaning the mounting slot, preventing bacterial growth or structural corrosion caused by the accumulation of cleaning fluid in the cavity 101. Furthermore, the baffle 200 is housed within the cavity 101, facilitating the installation of a door structure at the opening 102 for clearance and closure.

[0045] In an alternative embodiment of this application, the seal 300 is connected between the baffle 200 and the mounting portion 130.

[0046] The number of seals 300 may be one or more. In some examples, the material of seals 300 may be EPDM rubber, silicone rubber, or foam. In one example, the size of seal 300 is consistent with the mating surface size of baffle 200 and mounting part 130 to ensure complete coverage of the mating gap.

[0047] The seal 300 is located between the baffle 200 and the mounting part 130, which can effectively seal the gap between the two, prevent the cleaning fluid from leaking from the gap into the tailgate body 100 or the outside of the vehicle, and ensure that all the cleaning fluid is discharged through the drainage channel 120, thereby improving the reliability and hygiene of the tailgate.

[0048] Continue to refer to Figure 2 In an optional embodiment of this application, the tailgate body 100 further includes a circumferential cavity sidewall 140 disposed in the receiving cavity 101, the mounting part 130 is connected to the cavity sidewall 140, and the drainage channel 120 penetrates the cavity sidewall 140.

[0049] In some examples, the material of the cavity sidewall 140 is the same as that of the tailgate body 100, and can be aluminum alloy, high-strength steel plate or carbon fiber composite material.

[0050] The number of cavity sidewalls 140 is determined according to the cross-sectional shape of the receiving cavity 101. In one example, the receiving cavity 101 is a cuboid and there are four cavity sidewalls 140, corresponding to the front, back, left and right directions respectively. In another example, the receiving cavity 101 is a semi-cylinder and there are two semi-circular arc walls and two planar walls.

[0051] In some examples, the cavity sidewall 140 is positioned around the circumferential edge of the receiving cavity 101, connecting the bottom wall 110 of the cavity and the edge of the opening 102. The height of the cavity sidewall 140 is consistent with the depth of the receiving cavity 101, which can completely surround the side of the receiving cavity 101 and play a circumferential limiting role for kitchen utensils placed in the mounting slot.

[0052] In some examples, the connection between the mounting part 130 and the cavity sidewall 140 can be integral molding, welding, or bolting. In integral molding, the mounting part 130, the cavity sidewall 140, and the tailgate body 100 are integrally machined. This method has a compact structure, no connection gaps, and can improve the overall structural strength and sealing performance. It is suitable for tailgate bodies 100 formed by injection molding, die casting, or stamping.

[0053] The drainage channel 120 penetrates the cavity sidewall 140 by extending from the interior of the mounting portion 130 to the inner wall of the cavity sidewall 140, and then penetrating the outer surface of the cavity sidewall 140 to form a complete drainage path. The outlet of the drainage channel 120 on the cavity sidewall 140 can be located at the lower, middle, or upper part of the cavity sidewall 140.

[0054] For example, the connection between the drainage channel 120 and the cavity sidewall 140 can be provided with a transition fillet to reduce water flow resistance and avoid structural damage caused by stress concentration.

[0055] The cavity sidewall 140 is circumferentially arranged around the receiving cavity 101, effectively enhancing the structural strength of the tailgate body 100 and preventing deformation under stress. It also provides circumferential restraint for kitchen utensils within the mounting slot, preventing damage due to vibration during vehicle operation. The mounting part 130 is connected to the cavity sidewall 140, extending the fixing point of the mounting part 130 from the single cavity bottom wall 110 to the cavity sidewall 140, improving the support stability and load-bearing capacity of the mounting part 130 and preventing breakage or deformation due to concentrated stress during long-term use. The drainage channel 120 penetrates the cavity sidewall 140, extending the drainage path and allowing sewage to drain smoothly while reducing the risk of spillage. Furthermore, the cavity sidewall 140 creates a closed side structure for the receiving cavity 101, further improving the sealing of the mounting slot and protecting other internal structures of the tailgate body 100 from corrosion by cleaning fluid.

[0056] Furthermore, in some embodiments of this application, the mounting part 130 includes a first fixing part 131 and two second fixing parts 132. Along the length direction of the first fixing part 131, the two second fixing parts 132 are connected to both ends of the first fixing part 131, and the length direction intersects the direction of the cavity bottom wall 110 pointing to the opening 102.

[0057] The mounting portion 130 can be a hollow structure or a solid structure. In some examples, the material of the second fixing portion 132 is the same as that of the first fixing portion 131, and the cross-sectional shape of the second fixing portion 132 can be the same as that of the first fixing portion 131, which has a rectangular, circular, or other cross-sectional shape.

[0058] In some examples, the two second fixing parts 132 can be connected by integral molding, welding or bolting along the length of the first fixing part 131.

[0059] The mounting section 130 is divided into a first fixing section 131 and two second fixing sections 132, forming a frame-like support structure. Compared with a single block or strip-shaped mounting section 130, this structure effectively reduces the weight of the mounting section 130 while ensuring support strength, which is in line with the design trend of vehicle lightweighting. The two second fixing sections 132 are respectively connected to both ends of the first fixing section 131, which not only increases the connection area between the mounting section 130 and the cavity side wall 140 or cavity bottom wall 110, improving the fixing stability of the mounting section 130, but also evenly transmits the force of the first fixing section 131 to the tailgate body 100, avoiding structural damage caused by local stress concentration.

[0060] In one embodiment of this application, a drainage channel 120 is disposed on a first fixing part 131, with an opening 102 pointing toward the bottom wall 110 of the cavity, and the drainage channel 120 is recessed inward from the surface of the first fixing part 131 toward the baffle 200.

[0061] The extension direction of the drainage channel 120 can be parallel to or at an angle to the length direction of the first fixing part 131. For example, the drainage channel 120 is strip-shaped and extends along a first direction X, which can be vertical. In another example, the drainage channel 120 includes a main channel and auxiliary channels, with multiple auxiliary channels on both sides of the main channel. The auxiliary channels are connected to the main channel to form a branched drainage structure. This method can quickly collect cleaning fluid from different locations in the installation tank, improving the drainage speed.

[0062] In some examples, the recess of the drainage channel 120 may be U-shaped, V-shaped, or trapezoidal.

[0063] The drainage channel 120 is disposed in the first fixing part 131. Taking advantage of the position of the first fixing part 131, the drainage channel 120 is closer to the bottom area of ​​the mounting groove. Under the action of gravity, the cleaning fluid can quickly collect in the drainage channel 120, improving drainage efficiency and shortening the drainage path. The drainage channel 120 is recessed inward from the surface of the first fixing part 131 toward the baffle 200, eliminating the need for additional drilling inside the mounting part 130, simplifying the manufacturing process and reducing production costs. At the same time, the recessed structure prevents the cleaning fluid from overflowing during flow, ensuring drainage stability.

[0064] Specifically, in some embodiments of this application, the cavity bottom wall 110 includes a first wall portion 111 and a second wall portion 112. The second wall portion 112 is connected between the first wall portion 111 and the mounting portion 130. The drainage channel 120 extends along a first direction X, which intersects with the direction of the cavity bottom wall 110 pointing towards the opening 102. In the orthographic projection plane along the first direction X, the orthographic projection of the second wall portion 112 is located between the orthographic projection of the first wall portion 111 and the orthographic projection of the mounting portion 130. In the orthographic projection plane along the direction of the cavity bottom wall 110 pointing towards the opening 102, the orthographic projection of the second wall portion 112 is located between the orthographic projection of the first wall portion 111 and the orthographic projection of the mounting portion 130.

[0065] In some examples, the shape of the second wall portion 112 may be inclined, curved, etc. As an example, the first wall portion 111 may be a flat surface.

[0066] In some examples, the second wall portion 112 can be connected to the first wall portion 111 and the mounting portion 130 by means of integral molding, welding or bolting.

[0067] In one example, the first direction X can be perpendicular to the direction from the bottom wall 110 of the cavity to the opening 102.

[0068] In one example, in the orthographic projection plane along the first direction X, the orthographic projection of the second wall portion 112 is located between the orthographic projection of the first wall portion 111 and the orthographic projection of the mounting portion 130, such that there is a gap between the first wall portion 111 and the mounting portion 130. The orthographic projection of the second wall portion 112 is located between the orthographic projection of the first wall portion 111 and the orthographic projection of the mounting portion 130. The height of the second wall portion 112 is lower than the protrusion height of the mounting portion 130 and higher than the height of the first wall portion 111, so that the projection of the second wall portion 112 in the vertical direction is between the two, forming a stepped projection structure.

[0069] The cavity bottom wall 110 is divided into a first wall portion 111 and a second wall portion 112. The second wall portion 112 serves as a transitional connection, making the connection between the first wall portion 111 and the mounting portion 130 smoother, avoiding stress concentration caused by right-angle connections, and improving the structural strength and deformation resistance of the cavity bottom wall 110. The orthographic projection position of the second wall portion 112 in the two orthographic projection planes creates a smooth transition shape in the internal space of the mounting groove, giving the second wall portion 112 a flow guiding function, reducing water flow resistance, and improving drainage efficiency.

[0070] In one embodiment of this application, the orthographic projection of the second wall portion 112 is located within the baffle 200 in the orthographic projection plane along the direction from the bottom wall 110 of the cavity to the opening 102.

[0071] In one example, the overall size of the baffle 200 is larger than the size of the second wall portion 112, and the orthographic projection range of the baffle 200 completely covers the orthographic projection range of the second wall portion 112. In another example, the baffle 200 has a stepped structure, with a matching stepped surface provided at the position corresponding to the second wall portion 112. The orthographic projection range of the stepped surface is consistent with the orthographic projection range of the second wall portion 112, so that the orthographic projection of the second wall portion 112 is exactly located within the orthographic projection of the stepped surface. In yet another example, the shape of the second wall portion 112 is adapted to the shape of the baffle 200. The orthographic projection of the second wall portion 112 is rectangular, circular, or other regular shape, and the orthographic projection of the baffle 200 is correspondingly set to a larger structure of the same shape to ensure that the orthographic projection of the second wall portion 112 is completely located within the baffle 200.

[0072] The orthographic projection of the second wall portion 112 lies within the baffle 200. The complete coverage of the second wall portion 112 by the baffle 200 enhances the structural integrity of the mounting groove, allowing kitchen utensils to be placed within it with more even force, preventing shaking or damage caused by partial uncovering, and improving the reliability and practicality of the tailgate. Furthermore, this projection position optimizes the installation layout of the baffle 200, making the stress points of the baffle 200 more reasonable, reducing localized stress concentration, and extending the service life of the baffle 200.

[0073] In one example, the tailgate body 100 is formed as a single piece.

[0074] The tailgate body 100 can be formed in one piece using injection molding, die casting, stamping, composite molding, or 3D printing.

[0075] The tailgate body 100 is integrally molded, reducing assembly steps for multiple components, lowering assembly and labor costs. It also avoids gaps that may occur during assembly, improving the overall sealing of the tailgate body 100 and preventing rainwater, dust, or cleaning fluid from entering the interior, protecting the internal structure from corrosion. The integral molding structure allows for more even stress distribution on the tailgate body 100, eliminating weak points and enhancing overall structural strength and resistance to deformation. This allows it to better withstand vibrations and impacts during vehicle operation, extending the tailgate's lifespan.

[0076] like Figure 3 As shown, in some optional embodiments of this application, the baffle 200 is a flat plate, and the orthographic projection of the mounting part 130 is located within the orthographic projection of the baffle 200 in the direction from the bottom wall 110 of the cavity to the opening 102.

[0077] In some examples, the baffle 200 can be made of aluminum alloy plate, stainless steel plate, engineering plastic plate or tempered glass plate, etc.

[0078] In some examples, the area of ​​the baffle 200 is larger than the area of ​​the mounting portion 130, and the length and width of the baffle 200 are larger than the length and width of the mounting portion 130, so that the orthographic projection of the mounting portion 130 is completely within the orthographic projection range of the baffle 200; or, the shape of the mounting portion 130 is adapted to the shape of the baffle 200, and the orthographic projection of the mounting portion 130 is a rectangle, a circle or other regular shape, and the orthographic projection of the baffle 200 is a structure of the same shape but larger in size, so that the orthographic projection of the mounting portion 130 is exactly located in the central area of ​​the orthographic projection of the baffle 200.

[0079] In some examples, the mounting position of the baffle 200 can be adjusted to be fully fitted with the upper surface of the mounting part 130.

[0080] The baffle 200 is flat, with a simple structure, easy processing, low production cost, and a smooth surface, facilitating its fit with the mounting part 130 and improving sealing reliability. The flat structure makes cleaning the baffle 200 convenient; simply wiping the surface removes dirt, simplifying maintenance. The orthographic projection of the mounting part 130 along the direction from the bottom wall 110 towards the opening 102 falls within the orthographic projection of the baffle 200, ensuring complete coverage of the mounting part 130 and ensuring full contact between the sealing surfaces of the baffle 200 and the mounting part 130. This enhances the sealing effect and prevents cleaning fluid leakage from the edges of the mounting part 130. The baffle 200's edge extends beyond the edge of the mounting part 130, further expanding the sealing range and improving sealing reliability. It also protects the connection structure of the mounting part 130 from damage caused by external factors.

[0081] Continue to refer to Figure 3 In some embodiments of this application, the sealing element 300 includes multiple sealing strips 301, which are located on both sides of the drainage channel 120 in the orthographic projection plane along the direction of the cavity bottom wall 110 toward the opening 102.

[0082] For example, the material of the sealing strip 301 may be EPDM rubber, silicone rubber, fluororubber sealing sponge pad or foamed rubber.

[0083] In some examples, the sealing strip 301 may have a circular cross-section, a rectangular cross-section, an irregular cross-section, or a hollow cross-section. The sealing strip 301 may be straight, L-shaped, etc.

[0084] In one example, two sealing strips 301 are positioned at intervals on the left and right sides of the drainage channel 120, increasing the radial distance between the drainage channel 120 and the baffle 200. That is, the sealing strips 301 do not cover the drainage channel 120.

[0085] In the projected plane, multiple sealing strips 301 are located on both sides of the drainage channel 120, so that the sealing strips 301 avoid the drainage channel 120, thereby improving the unobstructed flow of the drainage channel 120, reducing the erosion of the seal 300 by the liquid discharged from the drainage channel 120, improving the sealing quality, and extending the sealing life.

[0086] In some embodiments, the tailgate body 100 has multiple drainage channels 120.

[0087] In some examples, multiple drainage channels 120 are evenly spaced along the length of the mounting portion 130, or are respectively arranged on both sides of the first fixing portion 131, or multiple drainage channels 120 converge in the mounting portion 130 and discharge together.

[0088] In some examples, when the drainage channels 120 are evenly spaced along the length of the mounting section 130, the number of channels 120 may be two, three, or four, etc.

[0089] The cross-sectional dimensions of multiple drainage channels 120 can be the same or different. When the dimensions are the same, the drainage flow is uniform and the processing technology is simple. When the dimensions are different, they can be set according to the drainage needs of different areas in the installation groove.

[0090] The multiple drainage channels 120 increase drainage flow and speed, preventing cleaning fluid from accumulating in the mounting groove and reducing the risk of bacterial growth and structural corrosion. These multiple drainage channels 120 can serve as backups for each other; even if one is blocked, the others can still function normally, improving the reliability of the drainage system. Furthermore, the layout of the multiple drainage channels 120 can adapt to different mounting groove structures, optimizing drainage paths, improving cleaning effectiveness, and further enhancing the practicality and user experience of the tailgate.

[0091] Furthermore, some embodiments of this application also provide a vehicle including the tailgate of the above embodiments.

[0092] For example, the vehicle may be a passenger car, commercial vehicle, RV, off-road vehicle, or new energy vehicle, etc.

[0093] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
