Description

Technical Field

[0001] This utility model relates to the field of mattress technology, and in particular to an adjustable mattress and bed. Background Technology

[0002] As people increasingly pursue healthy and comfortable sleep, smart mattresses and electric beds with posture adjustment functions have become popular products on the market. These products typically use built-in drive mechanisms to raise and lower different areas of the bed to adapt to the user's posture needs in different scenarios such as resting, reading, and watching movies.

[0003] However, adjustable mattresses currently on the market still have some problems in actual use, which affects the user experience. Specifically, existing products lack sufficient ergonomic adjustment freedom; the head and back areas often use linked or fixed angle designs for height adjustment, making it difficult to meet the diverse support needs of users. On the other hand, existing mattress structures are usually either one-piece or modular. One-piece mattresses result in bulky products, making transportation inconvenient and increasing logistics costs; modular mattresses, while convenient to assemble, require users to assemble the mattress from scratch, which increases the user's burden.

[0004] Therefore, how to provide a mattress that allows for highly flexible adjustment and is easy to transport and assemble is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The main purpose of this utility model is to provide an adjustable mattress and bed to solve the above-mentioned technical problems.

[0006] In a first aspect, this utility model provides an adjustable mattress, comprising: A support frame includes a head frame, a back frame rotatably connected to the head frame, and a seat frame arranged sequentially; the seat frame includes a first seat and a second seat that can be folded relative to each other, and the first seat is rotatably connected to the back frame. The driving mechanism includes a head driving mechanism and a back driving mechanism; the head driving mechanism is connected to the head frame and is used to drive the head frame to rotate relative to the back frame; the back driving mechanism is connected to the back frame and is used to drive the back frame to rotate relative to the first seat.

[0007] The support frame further includes a leg frame, which is rotatably connected to the second seat; the drive mechanism further includes a leg drive mechanism, which is connected to the leg frame and is used to drive the leg frame to rotate relative to the second seat.

[0008] The head drive mechanism includes a linear actuator, the output end of which is connected to the head frame and the fixed end of which is connected to the back frame.

[0009] This also includes a mattress body, which covers the top of the support frame.

[0010] The mattress body has a cavity at its bottom, and the support frame is housed in the cavity. The opposite side walls of the cavity are respectively provided with positioning grooves, and the support frame is provided with positioning parts that cooperate with the positioning grooves. The positioning parts pass through the corresponding positioning grooves.

[0011] The positioning part is a strip-shaped structure and is respectively disposed on both sides of the head frame, the back frame and the seat frame along the width direction.

[0012] The cavity is provided with clearance holes on its opposite side walls, and the clearance holes are located between the head frame and the back frame, between the back frame and the first seat, and between the second seat and the leg frame, respectively.

[0013] The mattress body includes a lower layer of retaining foam and an upper layer of supporting foam. The retaining foam and the supporting foam form accommodating spaces at opposite ends of the retaining foam, and one end of the head frame and the leg frame are respectively disposed in the corresponding accommodating spaces.

[0014] The enclosure sponge includes a first enclosure portion and a second enclosure portion that are adjacent to each other along the length direction of the support frame. The first enclosure portion and the second enclosure portion together enclose the cavity. The positioning groove and the clearance hole are both provided on the two side walls of the first enclosure portion and the second enclosure portion along the width direction of the support frame.

[0015] It also includes a base frame, and the seat frame is detachably connected to the top of the base frame.

[0016] The bottom of the base frame is provided with multiple bed legs.

[0017] Secondly, this utility model also provides a bed, including an adjustable mattress as described in the first aspect.

[0018] The beneficial technical effects of this utility model are as follows: This adjustable mattress, through the establishment of independent head drive mechanism and back drive mechanism, realizes independent rotation of the head frame relative to the back frame and independent rotation of the back frame relative to the first seat, thereby improving the ergonomic adjustment freedom of the mattress and meeting the diverse needs of users for head and back support angles in different scenarios. At the same time, the seat frame adopts a first and second seat structure that can be folded relative to each other, so that the entire support frame can be compactly folded when not in use, significantly reducing the footprint and facilitating transportation. The manufacturer can assemble the mattress as a whole, fold it in half, and deliver it directly to the user's door, effectively reducing the assembly burden. Attached Figure Description

[0026] Please also refer to Figures 1-7This utility model embodiment provides an adjustable mattress, which aims to provide users with highly free posture adjustment functions to adapt to the needs of different scenarios such as resting, reading, and watching audio-visual content. Its structural design also takes into account the convenience of transportation and installation. The adjustable mattress 50 includes a support frame, which includes a head frame 13, a back frame 11 rotatably connected to the head frame 13, and a seat frame 12 arranged sequentially. The seat frame 12 includes a first seat portion 121 and a second seat portion 122 that can be folded relative to each other. The first seat portion 121 is rotatably connected to the back frame 11. A drive mechanism is also included, which includes a head drive mechanism 22 and a back drive mechanism 21. The head drive mechanism 22 is connected to the head frame 13 and is used to drive the head frame 13 to rotate relative to the back frame 11. The back drive mechanism 21 is connected to the back frame 11 and is used to drive the back frame 11 to rotate relative to the first seat portion 121.

[0027] In this embodiment, the adjustable mattress 50 includes a support frame and a drive mechanism.

[0028] The support frame is the basic skeleton that enables the mattress 50 to change shape, providing the main support for the user's body. In this embodiment, the support frame is composed of multiple segmented frame bodies connected by rotation. Specifically, the support frame includes a head frame 13, a back frame 11, and a seat frame 12 arranged sequentially.

[0029] The head frame 13 is located at the front end of the support frame and is mainly used to support the user's head and neck area.

[0030] The front end of the back frame 11 is rotatably connected to the head frame 13. This connection can be a hinge connection or a shaft connection, allowing the head frame 13 to rotate relative to the back frame 11 within a predetermined angle range. The back frame 11 is one of the longer parts of the support frame, used to support the user's back and waist.

[0031] The seat frame 12 supports the user's hips and thighs. To facilitate the folding and transport of the mattress 50, the seat frame 12 in this embodiment is designed as a segmented foldable structure, comprising a first seat portion 121 and a second seat portion 122 that can be folded relative to each other. The first seat portion 121 is rotatably connected to the rear end of the back frame 11; similarly, this connection can be a hinge connection. The second seat portion 122 is also rotatably connected to the first seat portion 121, allowing the first seat portion 121 and the second seat portion 122 to be folded together when the mattress 50 is folded. This allows the head frame 13 and the back frame 11 to be folded together with the leg frame 14 in subsequent embodiments, thereby significantly shortening the overall length of the mattress 50 in its folded state.

[0032] The head frame 13, back frame 11, first seat 121 and second seat 122 are rotatably connected to form a multi-segment hinged linkage structure, which provides a mechanical basis for the posture adjustment of the mattress 50.

[0033] The drive mechanism is a component that provides adjustment power to the support frame, and uses electrical energy to drive the raising and lowering of various parts of the mattress 50. In this embodiment, the drive mechanism includes a head drive mechanism 22 and a back drive mechanism 21, both of which are independent drive units and can achieve independent control of their respective frame parts.

[0034] The head drive mechanism 22 is connected to the head frame 13, and its function is to drive the head frame 13 to rotate relative to the back frame 11. When the head drive mechanism 22 is activated, the angle at which the head frame 13 is raised or lowered can be controlled, thereby providing optimal support for the user's neck.

[0035] The back drive mechanism 21 is connected to the back frame 11, and its function is to drive the back frame 11 to rotate relative to the first seat 121. By activating the back drive mechanism 21, the entire upper body support part (i.e., the head frame 13 and the back frame) can be raised or lowered, realizing the posture change from lying down to sitting up.

[0036] During operation, the user can control the head drive mechanism 22 and the back drive mechanism 21 via a controller (such as a wired handle or a wireless remote). For example, the user can first raise the back frame 11 to a comfortable angle using the back drive mechanism 21, and then fine-tune the angle of the head frame 13 using the head drive mechanism 22 to achieve the most ergonomic support posture, effectively solving the problem of insufficient adjustment freedom caused by the linkage or fixed angle design of the head and back in the prior art. At the same time, the foldable design of the seat frame 12 allows the entire mattress 50 to be easily folded to reduce packaging volume during factory shipping or user relocation, facilitating transportation and entry into narrow doorways or corridors.

[0037] In one embodiment, the support frame further includes a leg frame 14, which is rotatably connected to the second seat 122; the drive mechanism further includes a leg drive mechanism 23, which is connected to the leg frame 14 and is used to drive the leg frame 14 to rotate relative to the second seat 122.

[0038] In this embodiment, the support frame, in addition to the original head frame 13, back frame 11, and seat frame 12, also includes a leg frame 14. The leg frame 14 is located at the end of the second seat 122, that is, along the length of the mattress 50, at the end of the entire support frame, and its main function is to provide support for the user's leg area.

[0039] To allow for posture adjustment, the leg frame 14 is rotatably connected to the second seat 122. This connection is achieved via a hinge structure or a pivot, allowing the leg frame 14 to rotate around its connection point with the second seat 122 as an axis.

[0040] Accordingly, in order to achieve independent adjustment of the leg frame 14, this embodiment adds a leg drive mechanism 23 to the original head drive mechanism 22 and back drive mechanism 21. The leg drive mechanism 23 is connected to the leg frame 14 and its function is to provide power to drive the leg frame 14 to rotate relative to the second seat 122, thereby realizing the lifting or lowering function of the leg area.

[0041] By adding a leg frame 14 and a leg drive mechanism 23, the adjustable mattress 50 in this embodiment enables independent adjustment of three key body areas: the user's head, back, and legs. Users can adjust the backrest or legs individually, or simultaneously, according to their needs, to achieve more personalized and comfortable body postures such as a "zero-gravity" posture, thus enhancing the mattress 50's adjustability and user experience.

[0042] In this embodiment, a foot frame 15 is also hinged to the end of the leg frame 14 away from the second seat 122. The foot frame 15 is used to rest the user's feet. The foot frame 15 can move upward or downward in parallel when the leg frame 14 is raised or lowered.

[0043] In one embodiment, the head drive mechanism 22 includes a linear driver, the output end 2211 of which is connected to the head frame 13, and the fixed end 2212 of which is connected to the back frame 11.

[0044] In this embodiment, the head drive mechanism 22 is specifically implemented using a linear actuator (e.g., an electric actuator commonly used in the art). A linear actuator is a device that converts the rotary motion of a motor into linear reciprocating motion.

[0045] To achieve effective actuation of the head frame 13, the linear actuator is connected at both ends to the head frame 13 and the back frame 11, respectively. Specifically: The output end 2211 of the linear actuator (referring to the retractable push rod portion) is connected to the head frame 13. This connection point is located on the head frame 13 away from its axis of rotation with the back frame 11 to form an effective lever arm, thereby achieving a large rotation angle with a small stroke. The connection method is typically a pin connection or a hinge to allow for a small range of angular changes at the connection point during actuation.

[0046] The fixed end 2212 of the linear actuator (referring to the housing part where the motor and reduction mechanism are located) is connected to the back frame 11. Similarly, this connection point is also fixed to the back frame 11 at an appropriate position by means of a pin connection or hinge.

[0047] When the head needs to be raised, the controller activates the linear actuator, extending its output end 2211 to push the head frame 13 to rotate upwards about the axis connecting it to the back frame 11. When the head needs to be lowered, the controller reverses the linear actuator's operation, retracting its output end 2211 to pull the head frame 13 downwards. By using this linear actuator as the head drive mechanism 22, smooth and reliable control of the head frame 13's raising and lowering angle can be achieved.

[0048] In this embodiment, in addition to the head drive mechanism 22 using a linear actuator, the back drive mechanism 21 and the leg drive mechanism 23 can also be similarly used in the form of linear actuators, thereby achieving standardization of the entire drive system.

[0049] Specifically, for the back drive mechanism 21: the fixed end of the linear actuator (not separately labeled in the figure) can be connected to the first seat 121, and its output end (not separately labeled in the figure) is connected to the back frame 11. The connection point is located on the back frame 11 away from its axis of rotation with the first seat 121 to obtain sufficient driving force arm. When the output end of the linear actuator extends, it pushes the back frame 11 (along with the head frame above it) to rotate upward relative to the first seat 121, thereby raising the user's upper body. When the output end retracts, it drives the back frame 11 to descend smoothly.

[0050] For the leg drive mechanism 23: the fixed end of the linear actuator can be connected to the second seat 122, and its output end is connected to the leg frame 14. Similarly, the connection point is located on the leg frame 14 away from its axis of rotation with respect to the second seat 122. When the output end of the linear actuator extends, it pushes the leg frame 14 to rotate upward relative to the second seat 122, thereby raising the user's legs. When the output end retracts, it causes the leg frame 14 to descend.

[0051] By equipping the head, back, and leg drive mechanisms 23 with independent linear drives, users can independently adjust the head, back, and leg areas of the mattress 50 using a single controller.

[0052] In one embodiment, a mattress body 30 is also included, which covers the top of the support frame.

[0053] In this embodiment, the adjustable mattress 50 also includes a mattress body 30. The mattress body 30, as the part that directly contacts the user's body, is located above the support frame and covers the top of the support frame, thereby providing soft surface support and cushioning for the support frame.

[0054] Specifically, the mattress body 30 may be composed of multiple layers of elastic materials, such as a comfort layer (e.g., memory foam) that provides a soft touch and a support layer (e.g., high-resilience foam) that provides core support. These layers are laid out and fixed to the top surface of the support frame, so that when the support frame is adjusted in posture by a drive mechanism, the mattress body 30 can deform accordingly, providing a continuous, body-hugging support surface.

[0055] By adding a mattress body 30 to the support frame, the adjustable mattress 50 in this embodiment combines the skeleton (support frame) that realizes the mechanical adjustment function with the support layer (mattress body) that provides lying comfort, thus forming a fully functional and comfortable adjustable bed 60 product.

[0056] In one embodiment, a cavity 31 is provided at the bottom of the mattress body 30, the support frame is housed in the cavity 31, and positioning grooves 32 are respectively provided on the opposite side walls of the cavity 31. The support frame is correspondingly provided with positioning parts 33 that cooperate with the positioning grooves 32, and the positioning parts 33 pass through the corresponding positioning grooves 32.

[0057] In this embodiment, a cavity 31 is provided at the bottom of the mattress body 30. This cavity 31 is an internal space designed as a downward-opening concave structure, its shape and size matching the support frame, thereby allowing the support frame to be accommodated within the cavity 31. This design allows the support frame to be embedded into the mattress body 30, forming a single unit, while also facilitating transportation and installation.

[0058] Furthermore, to ensure the precise positioning and fixation of the support frame within the cavity 31, positioning grooves 32 are respectively provided on the opposite side walls of the cavity 31 (i.e., the inner walls on both sides along the width direction of the mattress 50). These positioning grooves 32 can be rectangular grooves or strip grooves, distributed at intervals along the length direction of the side walls, with their number and position corresponding to the structure of the support frame. The length direction of the positioning groove 32 itself is perpendicular to the width direction of the mattress 50, and the positioning groove 32 can be a through groove or a non-through groove.

[0059] Correspondingly, the support frame is provided with a positioning part 33 that mates with the positioning groove 32. This positioning part 33 can be a protruding strip-shaped structure, its size and shape matching the positioning groove 32. During assembly, the positioning part 33 passes through the corresponding positioning groove 32, thereby achieving a locking and fixing between the support frame and the cavity 31. Through the cooperation of the positioning part 33 and the positioning groove 32, the lateral and longitudinal positioning of the support frame within the mattress body 30 is achieved, effectively preventing unpredictable movement between the support frame and the mattress body 30 during operation.

[0060] In one embodiment, the positioning part 33 is a strip-shaped structure and is respectively disposed on both sides of the head frame 13, the back frame 11 and the seat frame 12 along the width direction.

[0061] In this embodiment, each part of the support frame (including the head frame 13, back frame 11, first seat 121, second seat 122, and leg frame) is provided with a corresponding positioning part 33. Specifically, each frame has strip-shaped structures extending from both sides (i.e., the left and right sides of the frame) along its width direction. These strip-shaped structures can be protruding strips made of metal, with a rectangular or T-shaped cross-section. The extension direction of each strip-shaped structure is parallel to the width direction of the frame, protruding outward by a certain distance to facilitate insertion into the positioning groove 32.

[0062] During assembly, the positioning parts 33 formed by these strip-shaped structures are correspondingly inserted into the positioning grooves 32 on opposite side walls of the cavity 31. For example, the strip-shaped structure on the left side of the head frame 13 is inserted into the corresponding positioning groove 32 on the left side wall of the cavity 31, and the strip-shaped structure on the right side is inserted into the corresponding positioning groove 32 on the right side wall; similarly, the strip-shaped structures of the back frame 11, the first seat 121, the second seat 122, and the leg frame 14 are also positioned in the same manner. Through this arrangement of strip-shaped structures on both sides along the width direction, multi-point fixation between the mattress body 30 and the support frame is achieved, effectively preventing relative sliding or displacement between the support frame and the mattress body 30 during mattress posture adjustment.

[0063] In one embodiment, the opposite side walls of the cavity 31 are respectively provided with clearance holes 34, the positions of which correspond to the space between the head frame 13 and the back frame 11, the space between the back frame 11 and the first seat 121, and the space between the second seat 122 and the leg frame 14.

[0064] In this embodiment, in addition to the positioning grooves 32, the opposite side walls of the cavity 31 (i.e., the inner walls of both sides along the width direction of the mattress 50) are also provided with clearance holes 34. These clearance holes 34 can be circular holes, elliptical holes, or other opening shapes suitable for clearance, and their number is set according to the rotating parts of the support frame. Specifically, the positions of the clearance holes 34 correspond to the rotating connection between the head frame 13 and the back frame 11, the rotating connection between the back frame 11 and the first seat 121, and the rotating connection between the second seat 122 and the leg frame 14. In addition, there are also clearance holes 34 at the connection between the first seat 121 and the second seat 122. The length direction of these clearance holes 34 is the same as the width direction of the mattress 50.

[0065] By creating these clearance holes 34, when the support frame is adjusted in posture (e.g., the head frame 13 rotates relative to the back frame 11, the back frame 11 rotates relative to the first seat 121, or the leg frame 14 rotates relative to the second seat 122), the material (such as foam) on the sidewalls of the cavity 31 can avoid being squeezed or stretched by the rotating parts, thus reserving space for relative movement at the rotating joints. This prevents the mattress body 30 material at the rotating parts from bulging or deforming during repeated adjustments, maintaining the flatness of the mattress 50.

[0066] In one specific embodiment, corresponding to the rotatable connection between the head frame 13 and the back frame 11, a through-hole 34 is provided on both the left and right side walls of the cavity 31. These through-holes 34 are positioned to align with the hinge or pivot connection points between the head frame 13 and the back frame 11. This arrangement ensures that when the head drive mechanism 22 drives the head frame 13 to rotate relative to the back frame 11 (e.g., raise it to a 45° angle), the material on the side walls of the cavity 31 can "contract" through the through-holes 34, thereby buffering the compressive force and maintaining a flat surface. The same applies to the through-holes 34 at other locations.

[0067] In one embodiment, the mattress body 30 includes a lower layer of retaining foam 35 and an upper layer of supporting foam 36. The retaining foam 35 and the supporting foam 36 respectively form accommodating spaces 37 at opposite ends. One end of the head frame 13 and the leg frame 14 are respectively disposed in the corresponding accommodating spaces 37.

[0068] In this embodiment, the mattress body 30 is composed of at least two layers of foam with different functions, specifically including a lower layer of retaining foam 35 and an upper layer of support foam 36. These two layers of foam are fixedly connected.

[0069] The support foam 36 is the main part of the mattress body 30, which directly provides support and comfort to the user when lying down. It can be made of one or more materials such as memory foam, latex or high-elasticity foam.

[0070] The retaining foam 35 is located below the supporting foam 36, and its main function is to form a structure for accommodating the supporting frame. Specifically, the retaining foam 35 forms receiving spaces 37 between its opposite ends (i.e., in the direction corresponding to the head and foot of the mattress 50) and the supporting foam 36 above it. These two receiving spaces 37 can be understood as grooves formed at both ends of the retaining foam 35.

[0071] During assembly, one end of the head frame 13 (i.e., the end away from its connection axis with the back frame 11) is disposed in the receiving space 37 corresponding to the head direction of the mattress 50; similarly, one end of the leg frame 14 (i.e., the end away from its connection axis with the second seat 122) is disposed in the receiving space 37 corresponding to the foot direction of the mattress 50.

[0072] By embedding the ends of the head frame 13 and leg frame 14 into the receiving space 37 formed by the surrounding foam 35 and support foam 36, the mattress body 30 is completely covered on the top and sides of the support frame. Combined with the positioning part 33 and positioning groove 32, the two are then secured. This embedded connection method makes the mattress body 30 more firmly attached to the support frame, preventing relative slippage during use.

[0073] In one embodiment, the enclosure sponge 35 includes a first enclosure portion 351 and a second enclosure portion 352 adjacent to each other along the length direction of the support frame, the first enclosure portion 351 and the second enclosure portion 352 together enclosing to form the cavity 31; the positioning groove 32 and the clearance hole 34 are both provided on the side walls of the first enclosure portion 351 and the second enclosure portion 352 along the width direction of the support frame.

[0074] In this embodiment, the barrier foam 35 is designed as a segmented structure. Specifically, the barrier foam 35 includes a first barrier portion 351 and a second barrier portion 352 that are adjacent to each other along the length direction of the support frame. The dividing line between the first barrier portion 351 and the second barrier portion 352 roughly corresponds to the folded connection between the first seat portion 121 and the second seat portion 122 in the seat frame 12.

[0075] The first barrier portion 351 and the second barrier portion 352 together constitute a complete barrier structure, which together enclose the cavity 31 to accommodate the entire support frame. This segmented design allows the barrier foam 35 to bend naturally with the folding of the support frame when the mattress 50 is folded for transport, without causing excessive compression.

[0076] Furthermore, the aforementioned positioning groove 32 and clearance hole 34 are specifically positioned on this segmented enclosure sponge 35. Both the positioning groove 32 and clearance hole 34 are located on the two side walls of the first enclosure portion 351 and the second enclosure portion 352 along the width direction of the support frame.

[0077] In other words, some positioning grooves 32 and clearance holes 34 are formed on the inner walls of both sides of the first enclosure 351 to mate with the front half of the support frame (such as the head frame 13, back frame 11, and first seat); other positioning grooves 32 and clearance holes 34 are formed on the inner walls of both sides of the second enclosure 352 to mate with the rear half of the support frame (such as the second seat 122 and leg frame). This arrangement ensures that each movable joint has corresponding clearance space, guaranteeing smooth adjustment.

[0078] In one embodiment, a base frame 40 is also included, with the seat frame 12 detachably connected to the top of the base frame 40.

[0079] In this embodiment, the bottom frame 40 is the lowest supporting structure of the entire mattress 50, providing stable basic support and balance. It is located below the support frame and is connected to the seat frame 12 via a detachable connection. This detachable connection can employ bolts, connectors, or other quick-release structures, allowing the seat frame 12 (and the entire support frame) to be separated from or installed on the bottom frame 40. For example, both the first seat portion 121 and the second seat portion 122 are detachably connected to the bottom frame 40 using bolts.

[0080] This design facilitates the packaging, transportation, and after-sales maintenance of the mattress 50. For example, during transportation, the entire mattress 50 can be disassembled into two parts: the bottom frame 40 and the upper support frame, which are packaged separately, reducing the overall volume. During home installation, assembly is quick and easy; simply fix the seat frame 12 to the top of the bottom frame 40 without the need for specialized tools.

[0081] In one embodiment, the bottom of the base frame 40 is provided with a plurality of bed legs 41.

[0082] In this embodiment, the bottom of the base frame 40 (i.e., the side away from the user) is provided with multiple bed legs 41. These bed legs 41 are used to raise the entire mattress 50 off the ground, so that it can be used as a complete bed 60. The bed legs 41 can be cylindrical, square, or other shaped support legs, and are fixed to the bottom of the base frame 40 by bolts or plug-in methods. In a preferred configuration, the bottom of the base frame 40 is provided with four bed legs 41, which are located at the four corners of the base frame 40 to form a stable four-point support.

[0083] like Figure 8 As shown, corresponding to the above-mentioned adjustable mattress, this utility model embodiment also provides a bed, the bed 60 including the mattress 50 of any of the aforementioned embodiments.

[0084] In this embodiment, the mattress 50 includes a support frame, a drive mechanism, and a mattress body covering it, which enables independent adjustment of the head, back, and legs.

[0085] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model 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 utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
