Description

Technical Field

[0001] This utility model belongs to the field of automotive interior technology, and in particular relates to a headrest structure with a foldable cup holder and a vehicle thereof. Background Technology

[0002] A car typically consists of a powertrain, chassis, body, and electrical system. The passenger compartment within the body system comprises front and rear seats, each consisting of a seat cushion, backrest, and headrest. To facilitate access to drinks while driving, car seats (especially rear seats) are often used as cup holders.

[0003] Most cup holders on car seats are for use in a normal seating position, where the armrest (such as the rear center armrest) is laid flat and the cup holder extends out from it. However, when users need to fold down the seat back for activities such as camping or sleeping, the armrest usually needs to be folded into the seat back, causing the cup holder on the armrest to be pressed against the seat cushion by the seat back, rendering the cup holder unusable.

[0004] To address this, a structure was developed that integrates cup holders into the headrest, allowing cups to be placed on one end of the headrest when the backrest is flat. Existing headrest cup holders mostly employ a flip-up structure. Typically, the headrest is divided into two parts, with one part hinged to the other. The cup holder is placed on the flip-up part of the headrest. In use, the two parts of the headrest are unfolded to reveal the cup holder. Furthermore, a torsion spring, damping sleeve, and other flip-up assembly structure are usually required between the two parts of the headrest. This structure makes the headrest complex. The cup holder folds inside the headrest, and the headrest itself must accommodate the flip-up assembly, increasing the overall thickness of the headrest. When the backrest is flat, the headrest protrudes further from the backrest, making it easy for the front seats to interfere with the unfolding of the rear headrests, thus affecting the convenience of using the cup holders. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a headrest structure and vehicle with a foldable cup holder, with the intention of reducing the external size of the headrest structure through a new structural design of the cup holder on the headrest, so that the headrest protrudes less relative to the backrest, avoiding interference from the front seat on the headrest, thereby solving the problem that the headrest structure is too large in the prior art, which affects the convenience of using the cup holder.

[0007] To achieve the above objectives, in a first aspect, this utility model provides a headrest structure with a foldable cup holder, comprising: A headrest body for connecting to the top of a backrest; a recessed portion is provided at the bottom of the headrest body for accommodating the top of the backrest. A cup holder assembly is disposed in the recessed portion; the cup holder assembly includes: The cup holder body is hinged to the inner top surface of the recessed portion; A support member, which is hinged to the cup holder body; The cup holder assembly moves between a first position and a second position; when the cup holder assembly moves to the first position, the cup holder body is attached to the inner top surface of the recess, and the support member is attached to the cup holder body; when the cup holder assembly moves to the second position, the cup holder body is positioned opposite to the inner side surface of the recess, and the end of the support member away from the cup holder body is connected to the inner side surface of the recess.

[0008] In existing technologies, headrests with cup holders typically employ a split structure, dividing the headrest into two parts. The first part is hinged to the second part. When the backrest is laid flat, the first part is flipped over, revealing the cup holder on its inner surface for inserting and supporting a cup, thus creating a space between the first and second parts to accommodate the cup. A torsion spring, damping sleeve, or other flipping assembly structure is usually also provided between the two parts. When the restriction on the first part is removed, the spring can push it to flip, automatically unfolding the cup holder for use; or the damping sleeve can cause the first part to flip slowly, preventing collisions. When the two parts of the headrest are combined, the cup holders and the flip assembly are housed inside the headrest. This requires more space inside the headrest to accommodate the cup holder folding structure, thus increasing the overall size of the headrest and causing it to protrude more from the backrest. To prevent the front seats from obstructing the folding and unfolding of the rear headrests, more space is needed between the front and rear seats. This increases the difficulty of designing the seating layout in the confined passenger compartment, or requires moving the front seats forward first to fold down and use the rear headrests smoothly, affecting the convenience of using the cup holders on the headrests. In addition, this structure makes the headrest complex, increasing not only the cost but also the risk of damage during use.

[0009] The present application uses the above solution to hide the cup holder component in the recessed part at the bottom of the headrest. When folded, the cup holder component can lie flat against the headrest, so that when the headrest is against the backrest, it can partially overlap with it, reducing the protrusion of the headrest relative to the backrest. This reduces the interference of the front seats on the headrest when the backrest is flat, and ensures that passengers can still unfold the cup holder to place drinks in the camping mode.

[0010] In some embodiments of this application, a limiting buckle is provided on the cup holder body; when the cup holder assembly moves to the first position, the support member engages with the limiting buckle.

[0011] In the technical solution, the structural design uses a limiting buckle at the end of the fold to lock the support to the cup holder body, forming a flat, integrated structure that fits against the headrest. This prevents the support from shaking freely and causing abnormal noise when the vehicle is bumpy, thus improving NVH quality. At the same time, the buckle can be released with one hand, and the unfolding operation remains convenient.

[0012] In some embodiments of this application, a limiting seat is provided on the inner side of the recess; when the cup holder assembly moves to the second position, the support member is inserted into the slot provided by the limiting seat.

[0013] In the technical solution, the structural design uses a limiting seat slot to position the end of the support at the end of the unfolding point, so that the support can stably support the cup holder body.

[0014] In some embodiments of this application, the support member includes: A support plate, wherein the two ends of the support plate are respectively designated as a first end and a second end; the first end of the support plate is hinged to the cup holder body; A snap-fit ​​plate is elastically connected to the second end of the support plate; the snap-fit ​​plate is provided with a snap-fit ​​part so that the width of the end of the support member connected to the limiting seat is greater than the opening width of the slot.

[0015] In the technical solution, the structure is designed with an elastic snap-fit ​​plate at the second end of the support plate. When inserted, the snap-fit ​​part is compressed by the slot and elastically resets after it is in place. This not only improves the stability of the connection between the support and the limit seat, but also provides tactile feedback for the insertion and realizes blind insertion and self-locking. Users can complete the unfolding without visual inspection, simplifying the operation steps in night or camping scenarios.

[0016] In some embodiments of this application, the limiting seat is a plate, including a limiting part and two connecting parts respectively disposed on both sides of the limiting part; the limiting part is disposed opposite to the inner side of the recess, and the connecting parts extend toward and connect to the inner side of the recess; the slot is a connecting hole disposed on the limiting part.

[0017] In the technical solution, the limiting seat adopts a bridge structure of "limiting part + two side connecting parts", which makes the interface of the limiting seat hollow and forms a partially closed cavity, simplifying the structure of the limiting seat, reducing the structural weight, and ensuring that the limiting seat has sufficient strength. At the same time, it improves the strength of the limiting part and avoids deformation caused by repeated insertion and removal.

[0018] In some embodiments of this application, the snap-fit ​​plate is disposed opposite to the support plate, and one end of the snap-fit ​​plate is integrally connected to one end of the support plate.

[0019] In the technical solution, the structural design allows the snap-fit ​​plate and the support plate to be integrally connected at one end to form a cantilever spring, eliminating the need for additional assembly of springs or metal clips. The mold is formed in one step, reducing the number of parts, shortening assembly time, and lowering costs.

[0020] In some embodiments of this application, when the cup holder assembly is moved to the second position, the snap-fit ​​plate extends into the cup holder body.

[0021] In the technical solution, the structural design further reduces the thickness of the cup holder assembly when folded, and makes the support closer to the cup holder body so that the two can be snapped together.

[0022] In some embodiments of this application, the cross-section of the headrest body is L-shaped.

[0023] In the technical solution, the structural design divides the headrest body into two parts, horizontal and vertical. The vertical side provides head protection, while the horizontal side forms a "hidden platform" for installing cup holder components. Furthermore, the headrest's shape is consistent with that of a standard headrest, eliminating the need to modify the mold and reducing costs.

[0024] In some embodiments of this application, the following are further included: A headrest rod, one end of which is connected to the headrest body, and the other end of which is used to connect to the top of the backrest; The headrest rod is connected to the inner top surface of the recess; two headrest rods are spaced apart, and the cup holder assembly is disposed between the two headrest rods.

[0025] In the technical solution, the structural design places the cup holder assembly between the two rods, realizing space reuse; on the other hand, the center of gravity of the cup holder falls at the midpoint of the line connecting the two rods, improving the stability of the cup holder during use.

[0026] Secondly, this application provides a vehicle, including: The vehicle body, inside which seats are provided; The headrest structure with a foldable cup holder, as described above, is disposed on the seat.

[0027] In the technical solution, the structural design reduces the space occupied by the headrest after the vehicle adopts any of the above headrest structures. It increases the gap length between the rear headrest and the back of the front seat when the backrest is folded down. The front seat can be folded in one go without moving it forward, saving camping preparation time. The cup holder is completely hidden in the recess, which improves the visual cleanliness of the rear seats. The overall structure is simple and low cost.

[0028] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0036] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0037] It's important to note that in the automotive field, a car is generally composed of four main modules: the powertrain, chassis, body, and electrical system. The powertrain provides driving force; the chassis is responsible for transmission, driving, steering, and braking; the body constitutes the passenger compartment, housing the front and rear seats, which include seat cushions, backrests, and headrests; and the electrical system manages the vehicle's power supply and signaling. A headrest typically consists of a headrest body, a headrest rod, and an adjustment mechanism. The headrest body is covered with foam and a cover, and has an internal metal or plastic frame to support the head and mitigate impacts from rear-end collisions. The headrest rod inserts into the top guide sleeve of the backrest, allowing for height adjustment or tilting. Some models also integrate folding cup holders, audio systems, and cameras into the headrest body, fulfilling multiple needs for safety, comfort, and space utilization.

[0038] In existing technology, to meet camping needs, headrests with cup holders are used to hold cups after the rear seats are folded down. Current headrests with cup holders typically have a split structure, with the first part hinged to the second. When the backrest is flat, the first part is flipped up to expose the cup holder on its inner surface, providing support for the cup and creating a space between the first and second parts. When the rear seats are in use, the two parts of the headrest merge, concealing the cup holder and preventing it from being exposed and taking up space, while maintaining the headrest's aesthetics. A torsion spring or damping sleeve is usually also incorporated between the two parts of the headrest to facilitate a flipping assembly. When the restriction on the first part is lifted, the spring can push it to flip, automatically unfolding the cup holder for use; or the damping sleeve can cause the first part to flip slowly, preventing collisions. When the two parts of the headrest are combined, the cup holders and the folding assembly are housed inside the headrest. This requires more space inside the headrest to accommodate the folding cup holders, increasing the overall size of the headrest and causing it to protrude more from the backrest. Due to the limited space in the passenger compartment, if the distance between the front and rear seats is small, an excessively large headrest will cause the headrest to touch the backrest of the front seat when the backrest is folded down, hindering the folding down of the rear seat backrest. Even if the rear seat backrest can be folded down, the distance between the headrest and the front seat is too small to unfold the headrest for the cup holders, requiring the front seats to be moved forward. This not only reduces front passenger space, potentially making the front seats unusable, but also makes folding down the seats for camping preparations more cumbersome and time-consuming, affecting usability. Alternatively, the distance between the front and rear seats could be increased. However, the limited space in the passenger compartment may not allow for this seating arrangement, and even if the distance between the front and rear seats could be increased, it would increase the difficulty of designing the seating layout in the passenger compartment. In addition, this structure makes the headrest complex, which not only increases the cost but also increases the risk of damage during use.

[0039] Based on this, this application proposes a headrest structure with a foldable cup holder, which aims to reduce the external size of the headrest structure through a new structural design of the cup holder on the headrest, so that the headrest protrudes less relative to the backrest, avoids interference from the front seat on the headrest, and solves the problem that the headrest structure is too large in the prior art, which affects the convenience of using the cup holder.

[0040] See Figure 1 , Figure 3 and Figure 5In one illustrative embodiment of the headrest structure with a foldable cup holder in this application, the headrest structure includes a headrest body 100. When the seat back 1 is upright, the headrest body 100 is typically positioned above the backrest 1. A downwardly extending headrest rod 300 is typically provided on the headrest body 100. The headrest rod 300 is inserted into a guide sleeve 400 provided at the top of the backrest 1, thereby connecting the headrest body 100 to the backrest 1 and providing support for the headrest body 100, allowing the headrest body 100 to effectively support the occupant's head. The height of the headrest body 100 can be adjusted by sliding the headrest rod 300 within the guide sleeve 400 to accommodate different occupant head positions. A limiting structure is typically provided on the guide sleeve 400 to limit and fix the headrest rod 300, thereby fixing the headrest body 100 at different heights to ensure it is always horizontally aligned with the occupant's head and provides good support.

[0041] Furthermore, a recessed portion 101 is provided at the bottom end of the headrest body 100, that is, a recessed portion 101 is provided at the end of the headrest body 100 near the backrest 1, so that when the headrest body 100 is lowered to be in contact with the top of the backrest 1, the top of the backrest 1 can enter into the recessed portion 101, so that the top of the backrest 1 and the headrest body 100 can partially overlap in the horizontal direction. The inner top surface of the recessed portion 101 is arranged opposite to the end face of the top of the backrest 1, and the two can be in contact; the inner side surface of the recessed portion 101 is usually arranged opposite to the front or rear surface of the top of the backrest 1, and the two can be in contact.

[0042] See Figures 1 to 6 In some embodiments, the headrest structure with a foldable cup holder also includes a cup holder assembly 200. The cup holder assembly 200 is disposed in the recess 101 so that when the backrest 1 is laid flat, it unfolds in the space between the inner top surface of the recess 101 and the top of the backrest 1 to support and fix the cup.

[0043] The cup holder assembly 200 includes a cup holder body 201. The cup holder body 201 is generally annular, so that when a cup is placed inside the cup holder body 201, the cup holder body 201 fits over the cup, providing lateral support and preventing the cup from tipping over. The cup holder body 201 is hinged to the inner top surface of the recess 101, allowing the cup holder body 201 to be flipped.

[0044] The cup holder assembly 200 also includes a support member 202. The support member 202 is hinged to the cup holder body 201, allowing the support member 202 to be flipped.

[0045] By flipping the cup holder body 201 and the support member 202, the cup holder assembly 200 moves between a first position and a second position. See also Figure 1 and Figure 2When the cup holder assembly 200 is in the first position, it is in a folded state. At this time, the cup holder body 201 is attached to the inner top surface of the recessed portion 101, and the support member 202 is attached to the cup holder body 201, so that the cup holder assembly 200 is entirely attached to the inner surface of the recessed portion 101, occupying very little space between the headrest body 100 and the top of the backrest 1. This allows the headrest body 100 to be as close to the backrest 1 as possible, reducing the height of the seat and preventing interference from the front seat when it is folded down. Furthermore, a larger gap can be left between the headrest and the front seat. (See also...) Figure 3 and Figure 4 When the cup holder assembly 200 is in the second position, it is in the unfolded state. At this time, the cup holder body 201 is arranged opposite to the inner side of the recess 101, and the end of the support member 202 away from the cup holder body 201 is connected to the inner side of the recess 101. Thus, when the seat is reclined, the cup holder body 201 is in the horizontal direction, and the support member 202 is in the vertical direction to support the cup holder body 201.

[0046] The design incorporates a cup holder assembly 200 hidden within a recess 101 on the lower side of the headrest body 100. The cup holder assembly 200 is essentially located on the outside of the headrest body 100, thus not increasing the complexity of the internal structure of the headrest body 100. The design is simple and inexpensive. Secondly, when folded, the cup holder assembly 200 can lie flat against the inner top surface of the recessed portion 101 of the headrest body 100, occupying minimal space between the headrest body 100 and the top of the backrest 1. The headrest body 100 can be as close as possible to and against the top of the backrest 1, allowing it to partially overlap with the backrest 1 when it is against it, reducing the headrest's protrusion relative to the backrest 1. This avoids obstruction of the front seats when the backrest 1 is folded down, eliminating the need for the front seats to move forward, reducing the steps required for camping preparation, ensuring usable space for the front seats, and providing sufficient space for the front seats and the folded-down headrests of the rear seats. This allows the rear headrests to move forward after the backrest 1 is folded down, providing space for the cup holder assembly 200 to unfold between the headrest body 100 and the top of the backrest 1. The front and rear seats do not require a large gap, reducing the difficulty of seat layout design in the passenger cabin. Furthermore, when the cup holder assembly 200 is unfolded, after the cup passes through the cup holder body 201 from top to bottom, the bottom of the cup can rest on the inner side of the recess 101, allowing the cup to receive direct vertical support from the headrest body 100 and improving the stability of the cup. The recess 101 typically has only one inner side, allowing one side of the headrest body 100 to be open so that the cup can be placed on the cup holder assembly 200 within the recess 101 when the headrest is laid down.

[0047] See Figure 2 , Figure 4 and Figure 5In some embodiments, the cup holder body 201 is provided with a limiting buckle 203, which is typically a protrusion with a smooth surface. When the cup holder assembly 200 moves to the first position, the support member 202 engages with the limiting buckle 203, preventing the support member 202 from flipping away from the cup holder body 201 and keeping the support member 202 in contact with the limiting buckle 203. When the cup holder assembly 200 needs to be unfolded to the second position, an external force pulls the support member 202, causing the support member 202 to overcome the restriction of the limiting buckle 203 and disengage from the cup holder body 201. This allows the support member 202 to be flipped to a vertical position when the backrest 1 is reclined, thus supporting the cup holder body 201.

[0048] A connecting seat is typically provided at one end of the cup holder body 201, and a hinge seat is provided on the inner top surface of the recess 101. The hinge seat is usually composed of two hinge plates spaced apart. The connecting seat is located between the two hinge plates. The hinge shaft is usually a bolt structure that passes through the connecting seat and the hinge seat and is threaded with a mounting nut, allowing the cup holder body 201 to rotate around the hinge shaft. When the mounting nut is suspended, the mounting nut and the head of the hinge shaft away from the mounting nut tighten the hinge seat, causing the two hinge plates to press tightly against the cup holder body 201. The resulting friction keeps the cup holder body 201 stable without being pushed by an external force. An external force pushes the cup holder body 201 to overcome the friction and achieve its rotation. Since the cup holder body 201 is usually annular, a bushing is usually provided at one end of the support member 202. The bushing is directly fitted onto the cup holder body 201 to achieve the rotation of the support member 202. However, this structural design does not restrict the rotation of the support member 202.

[0049] In its folded state, this structural design uses a limiting buckle 203 to lock the support member 202 onto the cup holder body 201, resulting in a seamless, flat cup holder assembly 200 that rests against the inner top surface of the recess 101 of the headrest body 100. Since the cup holder assembly 200 typically faces downwards during normal use of the rear seats, this design restricts the rotation of the support member 202, preventing it from drooping down and extending into the space between the headrest body 100 and the top of the backrest 1 under gravity. This ensures the cup holder assembly 200 is concealed and aesthetically pleasing. Furthermore, the stable engagement of the support member 202 with the cup holder body 201 enhances its stability, preventing it from wobbling and causing noise during vehicle vibrations, thus improving NVH quality. Additionally, the engagement of the support member 202 can be operated with one hand, making the cup holder assembly 200 easy to unfold.

[0050] See Figures 1 to 4In some embodiments, a limiting seat 102 is provided on the inner side of the recess 101, and a slot 103 is provided on the limiting seat 102. When the inner side of the recess 101 faces upward, the slot 103 is usually upward-facing. When the cup holder assembly 200 moves to the second position, the support member 202 is inserted into the slot 103 provided in the limiting seat 102. This structural design allows the support member 202 to maintain stability in the horizontal direction when the backrest 1 is flat, through the insertion between the support member 202 and the limiting seat 102. The support member 202 is properly positioned vertically, stably supporting the cup holder body 201, which in turn allows the cup holder body 201 to stably support the cup, ensuring that the cup holder assembly 200 unfolds stably.

[0051] Furthermore, the headrest's rear cover 104 is typically disposed within the recess 101, and the rear cover 104 is further disposed within mounting grooves provided on the inner top surface and inner side surface of the recess 101. The cup holder body 201 is hinged to the portion of the rear cover 104 opposite to the inner top surface of the recess 101, and a limiting seat 102 is disposed on the portion of the rear cover 104 opposite to the inner side surface of the recess 101. When the cup holder assembly 200 is in the first position, it is tightly abutted against the inner top surface of the rear cover 104, thereby being hidden within the mounting grooves provided in the recess 101, further reducing the exposure of the cup holder assembly 200.

[0052] See Figure 5 In some embodiments, the support member 202 includes a support plate 2021. The two ends of the support plate 2021 are respectively designated as a first end and a second end. The first end of the support plate 2021 is hinged to the cup holder body 201. The support plate 2021 is typically hinged to one end of the cup holder body 201, and the other end of the cup holder body 201 is hinged to the inner top surface of the recess 101. This ensures that when the cup holder assembly 200 is folded, the support member 202 substantially overlaps with the cup holder body 201, reducing the space occupied by the cup holder assembly 200 in its folded plane.

[0053] The support member 202 further includes a snap-fit ​​plate 2022. The snap-fit ​​plate 2022 is elastically connected to the second end of the support plate 2021, such that when the snap-fit ​​plate 2022 moves relative to the support plate 2021, a spring force is generated on the snap-fit ​​plate 2022. The snap-fit ​​plate 2022 is provided with a snap-fit ​​portion 2022-1, which has a protruding structure, such that the width of one end of the support member 202 connected to the limiting seat 102 is greater than the length of the opening on the slot 103. Both the width of the support member and the width of the opening on the slot are external dimensions in a direction parallel to the inner side surface of the recess.

[0054] Along the direction in which the support member 202 is inserted into the limiting seat 102, the two ends of the snap-fit ​​portion 2022-1 are usually smoothly connected to the other parts of the snap-fit ​​plate 2022, so that during the process of inserting or removing the support member 202 into or from the slot 103, the opening of the slot 103 can move smoothly onto the snap-fit ​​portion 2022-1.

[0055] This structural design allows the support member 202 to be inserted into the slot 103. During this process, the opening of the slot 103 first clamps and compresses the portion of the support member 202 with the snap-fit ​​part 2022-1. After this portion of the support member 202 passes through the opening of the slot 103, it elastically returns to its original position. This makes the portion of the support member 202 with the snap-fit ​​part 2022-1 larger in size than the opening of the slot 103, thus preventing the support member 202 from coming out of the slot 103 and improving the stability of the connection between the support member 202 and the limiting seat 102. The reverse operation also causes the portion of the support member 202 with the snap-fit ​​part 2022-1 to be compressed and clamped first, and then elastically returned to its original position. This provides tactile feedback for proper insertion, achieving blind insertion and self-locking. Users can unfold the support member without visual inspection, simplifying the operation steps in nighttime or camping scenarios.

[0056] See Figure 2 In some embodiments, the limiting seat 102 is typically formed by stamping or bending a sheet metal, such that the limiting seat 102 includes a limiting part 1021 and two connecting parts 1022. The two connecting parts 1022 are respectively disposed on both sides of the limiting part 1021. The limiting part 1021 is disposed opposite to the inner side of the recessed part 101. The connecting parts 1022 extend towards the inner side of the recessed part 101 and connect with the inner side of the recessed part 101, thereby realizing the connection between the limiting seat 102 and the inner side of the recessed part. This results in the limiting seat 102 having a U-shaped cross-section, thus forming a hollow, partially closed cavity 1023 with openings at both ends inside the limiting seat 102. The slot 103 is a connecting hole provided on the limiting part 1021, thereby connecting the slot 103 to the partially enclosed cavity 1023. When the support member 202 is inserted into the limiting seat 102, the portion of the support member 202 with the snap-fit ​​part 2022-1 passes through the slot 103 and enters the partially enclosed cavity 1023. This structural design of the limiting seat 102 adopts a bridge structure of "limiting part 1021 + two side connecting parts 1022", which simplifies the structure of the limiting seat 102, makes the interior of the limiting seat 102 hollow, and reduces the structural weight. In addition, the two side connecting parts 1022 are usually arranged perpendicular to the limiting part 1021, thereby forming a reinforcing structure to strengthen the limiting part 1021, improve the strength of the limiting part 1021, and ensure that the limiting seat 102 has sufficient strength to avoid deformation of the limiting part 1021 caused by repeated insertion and removal.

[0057] See Figure 5In some embodiments, the snap-fit ​​plate 2022 is disposed opposite to the support plate 2021, and one end of the snap-fit ​​plate 2022 is integrally connected to one end of the support plate 2021. This structural design allows the support member 202 to be integrally bent to form the support plate 2021 and the snap-fit ​​plate 2022. The elasticity of the metal of the plate forms an elastic connection between the support plate 2021 and the snap-fit ​​plate 2022, so that the snap-fit ​​plate 2022 acts as a cantilever spring. When the snap-fit ​​part 2022-1 of the support member 202 contacts the opening of the slot 103, the snap-fit ​​plate 2022 moves towards the support plate 2021. The connection part 1022 undergoes elastic deformation, generating an elastic force that acts on the snap-fit ​​part 2022-1 and pushes it away from the support plate 2021. This achieves elastic reset of the support member 202 after the snap-fit ​​part 2022-1 disengages from the opening of the slot 103. No additional springs or metal clips are required. The mold is formed in one step, reducing the number of parts, shortening the assembly time, and reducing costs.

[0058] See Figure 1 and Figure 2 In some embodiments, when the cup holder assembly 200 moves to the second position, the snap-fit ​​plate 2022 extends into the cup holder body 201. Because the snap-fit ​​plate 2022 and the support plate 2021 create a double-layer structure for the support member 202, it has a certain thickness. Furthermore, the snap-fit ​​plate 2022, due to the snap-fit ​​portion 2022-1, protrudes relative to the support plate 2021. This structural design allows the stacked and protruding snap-fit ​​plate 2022 to enter the internal space of the cup holder body 201 when the cup holder assembly 200 is folded, effectively reducing the overall thickness of the cup holder assembly 200 after the support plate 2021 comes into contact with the cup holder body 201, thus reducing the space occupied by the cup holder assembly 200 when folded. Additionally, by bringing the support member 202 closer to the cup holder body 201, it facilitates the snap-fit ​​of the support member 202 with the limiting buckle 203 when it is provided on the cup holder body 201. Furthermore, since the snap-fit ​​plate 2022 and the support plate 2021 are opposite each other, and a gap needs to be left between them for the snap-fit ​​plate 2022 to move and generate elastic deformation, the protrusion of the limiting buckle 203 snaps into the snap-fit ​​plate 2022 and the support plate 2021, so that when the cup holder assembly 200 is folded, the limiting buckle 203 will not protrude from the support member 202, further ensuring a smaller thickness of the cup holder assembly 200 after folding.

[0059] See Figure 1 , Figure 3 and Figure 6In some embodiments, the headrest body 100 has an L-shaped cross-section. This structural design divides the headrest body 100 into two parts, a horizontal and a vertical one, with a recessed portion 101 opening towards the rear and lower side between the two parts. When seated, the vertical part of the headrest body 100 provides support and protection for the head, while the bottom surface of the horizontal part of the headrest body 100 serves as a platform for mounting the cup holder assembly 200. This makes the shape of the headrest body 100 consistent with a standard headrest, eliminating the need to modify the mold and reducing costs. In addition, the recessed portion 101 is open at the rear, so that when the headrest is reclined, the recessed portion 101 opens upward to expose the unfolded cup holder assembly 200 and facilitates the vertical placement of cups onto the cup holder body 201 within the recessed portion 101.

[0060] See Figure 6 In some embodiments, the headrest structure with a foldable cup holder further includes a headrest rod 300. One end of the headrest rod 300 is typically fixedly connected to the headrest body 100, and the other end is typically connected to a guide sleeve 400 provided at the top of the backrest 1, thereby connecting the headrest body 100 to the backrest 1 and allowing for adjustment of the distance between the headrest body 100 and the backrest 1. Two headrest rods 300 are typically spaced apart, and the connection points of the headrest rods 300 on the headrest body 100 are all located on the inner top surface of the recess 101. The cup holder assembly 200 is disposed between the two headrest rods 300. This structural design allows the headrest rods 300 and the cup holder assembly 200 to be arranged laterally on the inner top surface of the recess 101 of the headrest body 100, achieving space reuse and effectively utilizing the installation space. In addition, when the backrest 1 is laid flat, the cup is placed between the two headrest rods 300 in the cup holder body 201, so that the headrest rods 300 on both sides support the two sides of the headrest body 100 respectively, thereby forming a more stable support for the cup on the cup holder body 201 and improving the stability of the cup holder in use.

[0061] Furthermore, this application also provides a vehicle, which includes a body. The body is the core structure of the vehicle, including a chassis and body panels. The chassis provides basic support and driving functions for the vehicle, while the body panels constitute the exterior of the vehicle and protect internal components. The interior of the body panels forms a passenger compartment, in which seats are provided. The vehicle further includes a headrest structure with a foldable cup holder as described above. The headrest structure with a foldable cup holder is mounted on the seat, more specifically, it is located on the seat backrest 1. By adopting this headrest structure with a foldable cup holder, the space occupied by the headrest is reduced, increasing the gap length between the rear headrest and the back of the front seat when the backrest 1 is folded down. The headrest can be folded into place in one go without moving the front seat forward, saving camping preparation time. The cup holder is completely hidden in the recess 101, improving the visual neatness of the rear seats. The overall structure is simple and inexpensive.
