Abstract
Description
Technical Field
[0001] This application relates to the technical field of vehicles, and specifically proposes a trunk cover assembly and a vehicle. Background Technology
[0002] Currently, most vehicle trunks are equipped with a toolbox and cover. The toolbox typically contains a spare tire and repair tools. Specifically, the toolbox and cover are usually attached using adhesive-backed Velcro. However, toolboxes are often made of EPP (expanded polypropylene) material, which has a smooth and porous surface. This results in insufficient adhesive adhesion of the traditional Velcro, making it prone to detachment. Furthermore, the connection reliability is poor under conditions such as vehicle vibration and changes in temperature and humidity. Utility Model Content

[0009] In some embodiments, the toolbox has a slot near the first card hole; the rear edge of the cover plate covers part of the slot.
[0010] In some embodiments, the buckle includes a base and a mating part that are connected to each other. The base is connected to the cover plate, and the mating part is engaged with the buckle hole. The mating part has a first inclined surface and a second inclined surface. The first inclined surface is set at an acute angle to the base, and the second inclined surface is set at an obtuse angle to the base.
[0011] In some embodiments, the mating part includes a first latch and a second latch, which are spaced apart to form a deformation space.
[0012] In some embodiments, the slot includes an elastic limiting portion having an inclined limiting surface, and the mating portion abuts against the inclined limiting surface.
[0013] Secondly, this application proposes a vehicle that includes the trunk cover assembly of the first aspect.

[0016] Specifically, this application replaces the traditional Velcro bonding method with a snap-on and snap-hole design, solving the problem that the traditional connection method is prone to falling off due to the smooth surface of the EPP tool box. This application improves the reliability of the connection between the cover and the tool box. In particular, when facing environmental factors such as vibration and temperature changes during vehicle operation, this application performs more stably than the Velcro bonding method.

[0036] Reference Figure 1 and Figure 2 This application provides a trunk cover assembly, which includes a toolbox 10 and a cover 20. The toolbox 10 has at least two latching holes 110, including a first latching hole 111 and a second latching hole 112; the cover 20 covers the toolbox 10 and has at least two latches 210, including a first latch 211 and a second latch 212. The first latch 211 is interference-fitted with the first latching hole 111, and the second latch 212 is clearance-fitted with the second latching hole 112.
[0037] In this application, the trunk cover assembly includes a toolbox 10 and a cover 20. The toolbox 10 has at least two locking holes 110 (a first locking hole 111 and a second locking hole 112), while the cover 20 has at least two corresponding latches 210 (a first latch 211 and a second latch 212). The first latch 211 is interference-fitted with the first locking hole 111, serving a positioning and connection function; the second latch 212 is clearance-fitted with the second locking hole 112, serving to assist in connection and absorb assembly tolerances. This design ensures the stability and reliability of the cover 20 during installation, while also facilitating the opening and removal of the cover 20.
[0038] Specifically, this application replaces the traditional Velcro bonding method with the design of buckle 210 and buckle hole 110, which solves the problem that the traditional connection method is easy to fall off due to the smooth surface of EPP tool box 10. This application improves the reliability of the connection between cover plate 20 and tool box 10. In particular, when facing environmental factors such as vibration and temperature changes during vehicle operation, this application performs more stably than the Velcro bonding method.
[0039] Understandably, the buckle 210 is located on the cover plate 20, and the locking hole 110 is located on the tool box 10. The cover plate 20 covers the tool box 10 downwards, so that the buckle 210 is inserted downwards into the locking hole 110. However, if the buckle 210 is located on the tool box 10 and the locking hole 110 is located on the cover plate 20, then when the cover plate 20 covers the tool box 10, the buckle 210 will be inserted upwards into the locking hole 110 and will have a protruding part relative to the cover plate 20, which may affect the user experience in the trunk.
[0040] In some embodiments, refer to Figure 1 and Figure 2 The locking hole 110 includes a third locking hole 113, and the buckle 210 includes a third buckle 213. The third buckle 213 and the third locking hole 113 are in clearance fit; the connection between the third buckle 213 and the first buckle 211 and the second buckle 212 is misaligned.
[0041] In this embodiment, three sets of snap-fit structures are provided, and the connection lines between the third snap 213 and the other two snaps 210 are staggered, that is, the three snaps 210 are distributed in a triangle, which makes the connection between the cover plate 20 and the tool box 10 more stable.
[0042] In some embodiments, refer to Figure 2 Along the front-rear direction X of the vehicle body, the cover plate 20 has a front edge 220 and a rear edge 230, a first buckle 211 is set near the rear edge 230, and a second buckle 212 and a third buckle 213 are set near the front edge 220 respectively.
[0043] In this embodiment, the three latches 210 are arranged on the cover plate 20 in a "two in front, one in the back" configuration. Specifically, the first latch 211 is engaged with the first latch hole 111 and is located at the rear, making it easy to lift the first latch 211 from the first latch hole 111 with one hand, that is, to lift the cover plate 20 from the rear. The front edge 220 of the cover plate 20 can abut against the tool box 10 for upward flipping (e.g., Figure 3 (as shown); while the two front buckles 210 (i.e., the second buckle 212 and the third buckle 213) have gaps with the corresponding buckle holes 110, so as to facilitate the upward flipping of the cover plate 20.
[0044] In some embodiments, the second buckle 212 and the second buckle hole 112 are interference-fitted along the left-right direction Y of the vehicle body, and the second buckle 212 and the second buckle hole 112 are clearance-fitted along the front-rear direction X of the vehicle body; the third buckle 213 and the third buckle hole 113 are clearance-fitted along the circumferential direction.
[0045] In this embodiment, refer to Figure 8 and Figure 9 Regarding the two front latches 210: one latch 210 (i.e., the second latch 212) has only a gap in the front-back direction X with the latch hole 110, which facilitates the cover plate 20 to flip up (it should be understood that the cover plate 20 needs at least a gap in the front-back direction X to flip up), and at the same time can limit the vibration of the cover plate 20 in the left-right direction Y; the other latch 210 (i.e., the third latch 213) has a gap in all directions with the latch hole 110, which can absorb tolerances and facilitate assembly.
[0046] In some embodiments, the interference between the first latch 211 and the first latch hole 111 is 'a', and satisfies 0.2mm ≤ a ≤ 0.5mm; and / or, referring to... Figure 8 The maximum gap between the second buckle 212 and the second buckle hole 112 is b, and satisfies 0.5mm≤b≤1mm; and / or, refer to Figure 9 The gap between the third buckle 213 and the third buckle hole 113 is c, and satisfies 0.5mm≤c≤1mm.
[0047] In this embodiment, the interference amount 'a' between the first buckle 211 and the first locking hole 111 should not be too large, otherwise it will cause the first buckle 211 and the first locking hole 111 to be too tightly engaged, making it difficult to assemble or disassemble the cover plate 20 and the tool box 10. At the same time, the interference amount 'a' should not be too small, otherwise the engagement will not be stable enough, affecting the connection effect. Therefore, the interference amount 'a' should be moderate. For example, 'a' can be any one of 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm and 0.5mm or within the range of any two of these values.
[0048] Furthermore, the maximum gap b between the second latch 212 and the second latch hole 112 should also be moderate, so as to absorb assembly tolerances, facilitate the upward flipping of the cover plate 20, and prevent the connection from being too loose. For example, b can be any one of 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1mm, or fall within any two of these values. Similarly, the gap c between the third latch 213 and the third latch hole 113 should also be moderate. For example, c can be any one of 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1mm, or fall within any two of these values.
[0049] In some embodiments, refer to Figure 3 The toolbox 10 has a groove 120, which is close to the first card hole 111; the rear edge 230 of the cover plate 20 covers part of the groove 120.
[0050] In this embodiment, the toolbox 10 is provided with a groove 120, and the rear edge 230 of the cover plate 20 covers part of the groove 120, so that it is convenient for personnel to insert their fingers into the groove 120 and lift the cover plate 20 upward, so that the first buckle 211 disengages from the first buckle hole 111.
[0051] In some embodiments, refer to Figure 4 The buckle 210 includes a base 201 and a mating part 202 that are connected to each other. The base 201 is connected to the cover plate 20, and the mating part 202 is engaged with the buckle hole 110. The mating part 202 is provided with a first inclined surface 2021 and a second inclined surface 2022. The first inclined surface 2021 is set at an acute angle to the base 201, and the second inclined surface is set at an obtuse angle to the base 201.
[0052] In this embodiment, a specific implementation of the buckle 210 is proposed, wherein the first inclined surface facilitates the buckle 210 to be pulled out of the buckle hole 110, and the second inclined surface facilitates the buckle 210 to be inserted into the buckle hole 110.
[0053] Specifically, refer to Figure 4 The buckle 210 also includes a connecting rod 203, which is located between the mating part 202 and the base 201. The first inclined surface 2021 is set at an obtuse angle to the axial direction of the connecting rod 203, and the second inclined surface 2022 is set at an acute angle to the axial direction of the connecting rod 203.
[0054] Optionally, refer to Figure 4 Both the first inclined surface 2021 and the second inclined surface 2022 are conical surfaces.
[0055] In some embodiments, refer to Figure 5The mating part 202 includes a first latch 2023 and a second latch 2024, which are spaced apart to form a deformation space 2025.
[0056] In this embodiment, when the buckle 210 is inserted into the card hole 110, the first latch 2023 and the second latch 2024 deform towards each other, making the insertion smoother. After the buckle 210 is inserted into the card hole 110, the first latch 2023 and the second latch 2024 move away from each other, thereby abutting against the tool box 10 on the inner wall of the card hole 110, forming a snap-fit engagement and a secure connection.
[0057] In some embodiments, refer to Figure 7 The card hole 110 includes an elastic limiting part 114, which has an inclined limiting surface 115, and the mating part 202 abuts against the inclined limiting surface 115.
[0058] In this embodiment, the diameter of the elastic limiting part 114 is slightly smaller than the diameter of the mating part 202. When the buckle 210 is inserted into the buckle hole 110, in addition to the buckle 210 itself deforming, the elastic limiting part 114 can also deform, so that the buckle 210 can be smoothly inserted into the buckle hole 110. Moreover, after insertion, the side wall of the elastic limiting part 114 (i.e., the inclined limiting surface 115) and the mating part 202 of the buckle 210 both generate a rebound force and press against each other, thereby preventing the buckle 210 from dislodging from the buckle hole 110.
[0059] In some embodiments, refer to Figure 6 and Figure 7 The toolbox 10 has a receiving groove 130 around the card hole 110, which cooperates with the base 201.
[0060] In this embodiment, when the mating part 202 of the buckle 210 is inserted into the card hole 110, the receiving groove 130 around the card hole 110 can accommodate the base 201 of the buckle 210, so that the cover plate 20 is relatively flat after covering the tool box 10.
[0061] Secondly, embodiments of this application provide a vehicle that includes the trunk cover assembly of the first aspect.
[0062] Therefore, the vehicle in the second aspect includes all the technical effects of the trunk lid assembly in the first aspect, which will not be elaborated further. Furthermore, it should be understood that the vehicle also includes other components, such as the powertrain and body structure, which will not be specifically described here.
[0063] Optionally, the vehicle may be a fuel-powered vehicle, a new energy vehicle, a hybrid vehicle, or a flying car.
[0064] In particular, the term "and / or" in this application should be understood as follows:
[0065] In the first case, the term “and / or” between the first subject and the second subject includes any of the following meanings: (1) only the first subject; (2) only the second subject; and (3) both the first subject and the second subject.
[0066] In the second case, the term "and / or" between the last two of three or more subjects means including at least any one of the subjects. For example, "first subject, second subject and / or third subject" has the same meaning as "first subject and / or second subject and / or third subject", specifically including the following combinations: (1) only the first subject; (2) only the second subject; (3) only the third subject; (4) first subject and second subject and no third subject; (5) first subject and third subject and no second subject; (6) second subject and third subject and no first subject; and (7) first subject, second subject and third subject;
[0067] Furthermore, the character " / " in this application indicates that the objects before and after it are in an "or" relationship.
[0068] Finally, although the embodiments of this application have been described above in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the concept of this application, and such modifications and variations all fall within the scope of protection of this application.
