Description

Technical Field

[0001] This application relates to the field of vehicle equipment technology, and more particularly to a vehicle. Background Technology

[0002] Vehicles are an important means of transportation, and users have increasingly higher requirements for the appearance of vehicles. For example, a continuous light strip at the rear of a vehicle can enhance its aesthetics.

[0003] The rear of a vehicle typically includes a tailgate outer panel and a light box. The light box is located below the tailgate outer panel in the vehicle's height direction. A through light can be installed inside the light box via a connector, forming a buffer gap between the top of the light box and the tailgate outer panel.

[0004] However, the uniformity of the gap between the outer panel of the tailgate and the through light in the aforementioned related technologies is poor, and it is easy for the outer panel of the tailgate and the through light to interfere with each other. Utility Model Content

[0005] In view of this, this application provides a vehicle to solve the technical problem in the above-mentioned related technologies that the width uniformity of the gap between the tailgate outer panel and the through light is poor, and that the tailgate outer panel and the through light are prone to mutual interference.

[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0007] This application provides a vehicle comprising:

[0009] A light box, connected to the outer panel of the rear door, the light box having a mounting groove;

[0010] A through light is provided in the mounting groove, and the through light has a connecting part facing the outer panel of the rear door;

[0011] A limiting device includes a body and a limiting part. One end of the body is connected to the outer panel of the rear door, and the other end is connected to the connecting part. The limiting part is disposed on the body and is clamped between the outer panel of the rear door and the connecting part to form a gap between the connecting part and the outer panel of the rear door. The limiting part is used to limit the gap size between the outer panel of the rear door and the through light.

[0012] This application provides a vehicle that uses a limiting device between a through light and the outer panel of the tailgate. The through light and tailgate are connected via the body of the limiting device, and the limiting part of the limiting device is positioned within the gap between the through light and the tailgate. This allows the tailgate and the through light to simultaneously clamp the limiting part, making the gap approximately equal to the thickness of the limiting part. This results in a more uniform gap along the length of the through light, preventing interference between the tailgate and the through light due to uneven gap size, and avoiding damage to the through light from pressure from the tailgate. Furthermore, the more uniform gap size along the length of the through light improves the aesthetics of the vehicle's rear end.

[0016] The snap-fit ​​part is located at one end of the body facing the outer panel of the back door. The outer panel of the back door has a mounting hole, and the snap-fit ​​part snaps into the mounting hole.

[0017] In some embodiments of this application, the latching portion includes a first latching member and a second latching member spaced apart from each other;

[0018] The first connector has a first protrusion on the side facing away from the second connector, and the second connector has a second protrusion on the side facing away from the first connector.

[0019] Along the first direction, the first protrusion and the second protrusion are spaced apart from the limiting portion, and the first protrusion and the second protrusion are used to abut against the wall surface of the outer panel of the back door facing away from the through light.

[0021] The abutting part is disposed on the side of the limiting part opposite to the locking part, and the abutting part and the limiting part are spaced apart so that a groove is formed between the abutting part and the limiting part;

[0022] The connecting part has a buckle, which engages with the slot.

[0023] In some embodiments of this application, the limiting device further includes a sealing structure;

[0024] The sealing structure is disposed between the limiting part and the outer panel of the back door, and the sealing structure is used to seal the mounting hole.

[0025] In some embodiments of this application, the limiting device has multiple components;

[0026] The limiting devices are spaced apart and evenly distributed along the length of the through lamp.

[0027] In some embodiments of this application, the limiting device has three parts, wherein two of the limiting devices correspond to the two ends in the length direction of the through lamp, and the other limiting device corresponds to the middle part in the length direction of the through lamp.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0052] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0053] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0054] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0055] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0056] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0057] In related technologies, the uniformity of the gap between the tailgate outer panel and the through light is poor, easily leading to interference between them. This problem arises because, in existing technologies, the tailgate outer panel is connected to the upper edge of the light box, taking the vehicle's length, width, and height as dimensions. When the through light is installed inside the light box, a certain gap is typically left between the upper edge of the through light and the tailgate outer panel to prevent the tailgate outer panel from squeezing the upper edge of the through light, thus providing a buffering effect. However, because the through light is relatively long in the width direction of the vehicle body, this gap is also relatively long in that direction. The tailgate outer panel, being a plate-like structure, can deform when its length is large, resulting in uneven distance between the tailgate outer panel and the upper edge of the through light in the width direction of the vehicle body. This leads to uneven gap width along the width direction of the vehicle body, and in some areas, the gap width may even be negative, meaning interference occurs between the tailgate outer panel and the through light. This can cause the tailgate outer panel to squeeze the through light, potentially damaging it.

[0058] To address the aforementioned problems, this application provides a vehicle that uses a limiting device between the through light and the tailgate outer panel. The through light and tailgate outer panel are connected via the body of the limiting device, and the limiting part of the limiting device is positioned within the gap between the through light and the tailgate outer panel. This allows the tailgate outer panel and the through light to simultaneously clamp the limiting part, making the gap size approximately equal to the thickness of the limiting part. This ensures a more uniform gap size along the length of the through light, preventing interference between the tailgate outer panel and the through light due to uneven gap size, and also preventing damage to the through light from pressure from the tailgate outer panel. Furthermore, the more uniform gap size along the length of the through light improves the aesthetics of the vehicle's rear end.

[0059] The mounting bracket provided in this application will now be described with reference to the accompanying drawings and specific embodiments.

[0060] Reference Figure 1 , Figure 2 and Figure 3 This application provides a vehicle, which can be a fuel-powered vehicle or a new energy vehicle, such as a pure electric vehicle (PEV / BEV), a range-extended electric vehicle (REEV), a hybrid electric vehicle (HEV), or a fuel cell electric vehicle. The vehicle can also be any vehicle equipped with a battery.

[0061] The vehicle may include a tailgate outer panel 100, a light box 200, a through light 300, and a limiting device 400. The vehicle may also include a vehicle body, and the tailgate outer panel 100, the light box 200, the through light 300, and the limiting device 400 may all be located at the rear of the vehicle body.

[0062] The tailgate outer panel 100 can be installed at the rear of the vehicle body. The tailgate outer panel 100 can be a metal plate, which can improve the structural strength of the tailgate outer panel 100.

[0063] The light box 200 is connected to the outer panel 100 of the tailgate, in the height direction of the vehicle body (e.g., Figure 1 The light box 200 (in the Z direction) is located below the tailgate outer panel 100. The light box 200 can be connected to the tailgate outer panel 100. The light box 200 may have a mounting groove 210, which can be mounted along the width direction of the vehicle body (e.g., in the Z direction). Figure 1 Extending in the X direction, the mounting slot 210 can be used to install the through light 300, and the light box 200 can protect the through light 300 in the mounting slot 210, reduce the probability of the through light 300 being bumped by external objects, and improve the protective performance of the through light 300.

[0064] The through light 300 may have a connecting portion 310 toward the outer panel 100 of the tailgate, and the through light 300 may extend along the width direction of the vehicle body.

[0065] The limiting device 400 may include a body 410 and a limiting part 420. One end of the body 410 is connected to the outer panel 100 of the tailgate, and the other end is connected to the connecting part 310. The limiting part 420 is disposed on the body 410 and is clamped between the outer panel 100 of the tailgate and the connecting part 310 to form a gap 500 between the connecting part 310 and the outer panel 100 of the tailgate. The limiting part 420 is used to limit the size of the gap 500 between the outer panel 100 of the tailgate and the through light 300.

[0066] When the limiting part 420 is clamped between the outer panel 100 of the tailgate and the connecting part 310, direct contact between the outer panel 100 of the tailgate and the connecting part 310 on the through light 300 can be avoided.

[0067] In some embodiments, the body 410 may be a bolt, screw, or rivet. The limiting part 420 may be a limiting block or limiting plate disposed on the body 410.

[0068] In some embodiments, when the tailgate outer panel 100 and the connecting portion 310 clamp the limiting portion 420, since the limiting portion 420 can prevent the tailgate outer panel 100 and the connecting portion 310 from getting closer together, it can be known that the size of the gap 500 can be approximately equal to the thickness of the limiting portion 420.

[0069] This application provides a vehicle in which a limiting device 400 is provided between a through light 300 and a tailgate outer panel 100. The through light 300 and the tailgate outer panel 100 are connected by the body 410 of the limiting device 400, and the limiting part 420 of the limiting device 400 is disposed within the gap 500 between the through light 300 and the tailgate outer panel 100. This allows the tailgate outer panel 100 and the through light 300 to simultaneously clamp the limiting part 420, making the size of the gap 500 approximately equal to the thickness of the limiting part 420. This makes the size of the gap 500 more uniform along the length direction of the through light 300, avoiding interference between the tailgate outer panel 100 and the through light 300 due to uneven gap 500 size, and preventing the through light 300 from being damaged by the tailgate outer panel 100. Furthermore, because the size of the gap 500 is more uniform along the length direction of the through light 300, the aesthetics of the vehicle's rear end are improved.

[0070] Reference Figure 1 and Figure 2 In some embodiments, there may be multiple limiting devices 400, which are spaced apart and evenly distributed along the length of the through lamp 300.

[0071] By setting multiple limiting devices 400, the size of the gap 500 between the connecting part 310 and the tailgate outer panel 100 can be limited by multiple limiting parts 420. The gap 500 is controlled by multiple limiting parts 420 along the width direction of the vehicle, increasing the area where the size of the gap 500 can be controlled. This further controls the amount of deformation of the tailgate outer panel 100, further reduces the impact of the deformation of the tailgate outer panel 100 on the size of the gap 500, and improves the uniformity of the size of the gap 500 in the width direction of the vehicle body.

[0072] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the limiting device 400 may have three, wherein two limiting devices 400 correspond to the two ends of the through lamp 300 in the length direction, and the other limiting device 400 corresponds to the middle part of the through lamp 300 in the length direction.

[0073] By setting three limiting devices 400, the uniformity of the dimensions at both ends and the middle of the gap 500 can be ensured. This reduces the number of limiting devices 400 used while ensuring that the overall dimensions of the gap 500 are relatively uniform, thereby reducing the manufacturing cost of the vehicle.

[0074] Reference Figure 3 and Figure 4 In some embodiments, the limiting part 420 can be a flange, which surrounds the outer periphery of the body 410, and the side of the flange facing the outer panel 100 of the back door abuts against the outer panel 100 of the back door, and the side of the flange facing the connecting part 310 abuts against the connecting part 310.

[0075] By setting the limiting part 420 as a flange, the manufacturing process of the limiting device 400 can be simplified, the production efficiency of the limiting device 400 can be improved, and the manufacturing cost of the limiting device 400 can be reduced, since the structure of the flange is relatively simple and easy to design and manufacture. The flange can surround the outer periphery of the body 410, so that the force on the limiting part 420 is more uniform, and the force transmitted from the limiting part 420 to the body 410 is more uniform, avoiding excessive concentration of the force of the limiting part 420 on the body 410.

[0076] Reference Figure 3 and Figure 4 In some embodiments, the limiting device 400 may further include a snap-fit ​​portion 430, which may be disposed at one end of the body 410 facing the outer panel 100 of the back door. The outer panel 100 of the back door may have a mounting hole 110, and the snap-fit ​​portion 430 snaps into the mounting hole 110.

[0077] By providing a snap-fit ​​portion 430 on the main body 410, the portion of the main body 410 with the snap-fit ​​portion 430 can be snapped into the mounting hole 110 on the outer panel 100 of the tailgate, and the snap-fit ​​portion 430 abuts against the inner surface of the outer panel 100 facing away from the through light 300, thereby connecting the limiting device 400 to the outer panel 100 of the tailgate. The snap-fit ​​connection method is relatively simple and easy to operate, and can improve the assembly efficiency between the outer panel 100 of the tailgate and the limiting device 400. The snap-fit ​​connection method can reduce the probability of the limiting device 400 coming out of the mounting hole 110 and can improve the connection stability between the outer panel 100 of the tailgate and the limiting device 400.

[0078] Reference Figure 3 and Figure 4 In some embodiments, the latching portion 430 may include a first latching member 431 and a second latching member 432 spaced apart. The side of the first latching member 431 facing away from the second latching member 432 may have a first protrusion 433, and the side of the second latching member 432 facing away from the first latching member 431 may have a second protrusion 434. Along a first direction, the first protrusion 433 and the second protrusion 434 are spaced apart from the limiting portion 420, and the first protrusion 433 and the second protrusion 434 are used to abut against the wall surface of the outer panel 100 facing away from the through light 300. The first direction may be the length direction of the body 410 of the limiting device 400.

[0079] The first snap-fit ​​component 431 and the second snap-fit ​​component 432 have a certain elastic deformation capability. When the first snap-fit ​​component 431 and the second snap-fit ​​component 432 do not deform, the maximum distance between the first protrusion 433 and the second protrusion 434 is greater than the diameter of the mounting hole 110.

[0080] When the first snap-fit ​​member 431 and the second snap-fit ​​member 432 approach each other through elastic deformation, the first protrusion 433 and the second protrusion 434 can approach each other, and the distance between the first protrusion 433 and the second protrusion 434 can be less than the diameter of the mounting hole 110, so that the first protrusion 433 and the second protrusion 434 can pass through the mounting hole 110. When the first snap-fit ​​member 431 and the second snap-fit ​​member 432 return to their original state, the first protrusion 433 and the second protrusion 434 can abut against the inner wall of the tailgate outer panel 100 facing away from the through light 300, so as to realize the snap-fit ​​connection between the snap-fit ​​part 430 and the tailgate outer panel 100.

[0081] By configuring the snap-fit ​​portion 430 as a first snap-fit ​​member 431 and a second snap-fit ​​member 432, and snap-fitting it to the outer panel 100 of the tailgate through the first protrusion 433 on the first snap-fit ​​member 431 and the second protrusion 434 on the second snap-fit ​​member 432, the manufacturing process of the limiting device 400 can be simplified, the production efficiency of the limiting device 400 can be improved, and the production efficiency of the vehicle can be improved.

[0082] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the limiting device 400 may further include an abutment portion 440, which is disposed on the side of the limiting portion 420 opposite to the engaging portion 430. The abutment portion 440 and the limiting portion 420 are spaced apart so that a groove 450 is formed between the abutment portion 440 and the limiting portion 420. The connecting portion 310 may have a buckle 311, which is engaged in the groove 450.

[0083] In this way, by forming a groove 450 between the abutment part 440 and the limiting part 420, and by engaging the buckle 311 on the connecting part 310 into the groove 450, the through light 300 and the limiting device 400 can be detachably connected. The connection method of engaging the buckle 311 with the groove 450 is relatively simple and easy for operators to operate, which can improve the assembly efficiency of the through light 300 and the limiting device 400, and thus improve the assembly efficiency of the vehicle.

[0084] Reference Figure 3 and Figure 4 In some embodiments, the limiting device 400 may further include a sealing structure 600, which is disposed between the limiting part 420 and the outer panel 100 of the back door, and is used to seal the mounting hole 110.

[0085] By setting the sealing structure 600, the gap between the mounting hole 110 and the limiting device 400 can be sealed, which can prevent liquids or debris from entering the vehicle body through the gap, and further prevent liquids or debris from entering the interior from causing corrosion or damage to the inner side of the tailgate outer panel 100 or the interior of the vehicle body.

[0086] In some embodiments, the sealing structure 600 can be an elastic sealing ring, which can be sleeved on the body 410 and pressed against the outer panel 100 of the back door by the limiting part 420. In a specific implementation, the elastic sealing ring can be an elastic rubber sealing ring.

[0087] Reference Figure 2 and Figure 3In some embodiments, the vehicle may further include a first positioning pin 700 disposed in the middle of the through-light 300. The bottom of the mounting groove 210 may have a first positioning hole 211 corresponding to the first positioning pin 700, the first positioning hole 211 extending along the height direction of the vehicle. The dimension of the first positioning hole 211 along the height direction of the vehicle is larger than the dimension along the width direction of the vehicle. In some embodiments, the first positioning hole 211 may be formed in the middle of the light box 200 along the width direction of the vehicle.

[0088] The first positioning pin 700 can be a structure adapted to the first positioning hole 211. For example, the dimension of the first positioning pin 700 along the vehicle height direction can be greater than the dimension along the vehicle width direction.

[0089] Thus, when the through light 300 needs to be centered within the light box 200 along the width of the vehicle, the positioning installation via the first positioning pin 700 and the first positioning hole 211 ensures that the through light 300 is centered within the light box 200, as the first positioning pin 700 is located in the middle of the through light 300. This makes the distances from both ends of the through light 300 along the width of the vehicle to both ends of the light box 200 nearly equal, preventing the through light 300 from being positioned close to one end of the light box 200 along the width of the vehicle. It also prevents the through light 300 from shifting along the width of the vehicle when installed with the light box 200 or the tailgate outer panel 100, improving the installation accuracy of the through light 300 within the light box 200 and increasing the installation efficiency of the through light 300.

[0090] In some embodiments, the alignment and installation of the first positioning pin 700 and the first positioning hole 211 can precede the installation of the connecting portion 310 and the limiting device 400 on the through lamp 300, thereby enabling the through lamp 300 to be positioned inside the lamp box 200 along the vehicle width direction before the connecting portion 310 and the limiting device 400 are connected.

[0091] Reference Figure 2 and Figure 3 In some embodiments, the vehicle may further include at least two second locating pins 800, which are disposed at both ends along the length of the through lamp 300. Two second locating holes corresponding to the second locating pins 800 are formed on the wall of the mounting groove 210, each second locating hole corresponding to one second locating pin 800. The second locating holes extend along the width direction of the vehicle. The dimension of the second locating hole along the width direction of the vehicle is larger than its dimension along the height direction of the vehicle.

[0092] The second positioning pin 800 can be a structure adapted to the second positioning hole. For example, the dimension of the second positioning pin 800 along the vehicle width direction can be larger than the dimension along the vehicle height direction. By inserting the second positioning pin 800 into the second positioning hole, the two ends of the through light 300 can be constrained in the vehicle height direction, limiting the displacement of the through light 300 in the vehicle height direction. This can prevent the through light 300 from shifting along the vehicle height direction when installed with the light box 200 or the tailgate outer panel 100, improving the installation accuracy of the through light 300 in the light box 200 and helping to improve the installation efficiency of the through light 300.

[0093] In some embodiments, the alignment and installation of the second positioning pin 800 and the second positioning hole can precede the installation of the connecting portion 310 and the limiting device 400 on the through lamp 300, thereby enabling the through lamp 300 to be positioned inside the lamp box 200 along the vehicle width direction before the connecting portion 310 and the limiting device 400 are connected.

[0094] In some embodiments, the number of second locating pins 800 may be two, three, four, or five.

[0095] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
