Abstract
Description
Technical Field
[0001] This application relates to the field of pet mat folding boards, and more particularly to a pet mat folding board. Background Technology
[0002] Some pet owners install pet seats in their cars so that their pets can sit or lie down. However, pet seats are usually made of soft fabric, which lacks support. When pets are standing, the lack of support makes them feel uncomfortable and insecure, which can lead to stress and panic.
[0003] Some existing pet cushions have a single piece of hard material inside. Pet cushions made of a single piece of hard material cannot be folded, which makes them take up a lot of space during transportation and inconvenient to transport.
[0004] Secondly, if a foldable pet seat is made by combining two hard materials, the two materials cannot remain on the same plane when unfolded after folding. When the pet uses it, it stands on the two adjacent hard boards. At this time, the two hard boards are connected by a fold line, which causes the two adjacent hard boards to be at an angle. The fold line will be concave downward due to the pet's weight, causing the two adjacent hard boards to tilt and not be on the same plane. This affects the levelness and results in poor support for the pet, which affects the pet's mood. Utility Model Content
[0005] In view of this, it is necessary to provide a pet mat folding board to solve the above problems.

[0024] The pet mat folding board implemented in this embodiment will have at least the following beneficial effects:
[0025] The aforementioned pet mat folding board, when folded, has its first fold section folded relative to the second fold section, causing the first fulcrum to move away from the second fulcrum, facilitating the storage of the pet mat folding board. When unfolded for use, the first fold section is unfolded, causing the second connecting surface to rotate relative to the first connecting surface. When the first and second supporting surfaces are on the same plane, the first and second fulcrums abut against each other, ensuring that the first and second supporting surfaces remain on the same plane.

[0042] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0043] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.
[0044] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0045] Embodiments of this application provide a pet mat folding board 100, comprising:
[0046] The first folding portion 110 has a first fulcrum 110b, a first support surface 111, and a first connecting surface 112 disposed opposite to the first support surface 111;
[0047] The second folding portion 120 has a second fulcrum 120b, a second support surface 121 and a second connecting surface 122 disposed opposite to the second support surface 121, wherein the second connecting surface 122 is rotatably connected to the first connecting surface 112.
[0048] Wherein, the first folding portion 110 is folded or unfolded relative to the second folding portion 120 so that the first fulcrum 110b is away from or close to the second fulcrum 120b. When the first fulcrum 110b and the second fulcrum 120b abut, the first support surface 111 and the second support surface 121 always remain in the same plane.
[0049] Please refer to Figures 1-10In this embodiment, when folded, the first folding part 110 folds relative to the second folding part 120, so that the first fulcrum 110b moves away from the second fulcrum 120b, so as to facilitate the storage of the pet mat folding board 100. When unfolded for use, the first folding part 110 is unfolded, so that the second connecting surface 122 rotates relative to the first connecting surface 112. When the first support surface 111 and the second support surface 120b are on the same plane, the first fulcrum 110b and the second fulcrum 120b abut against each other, which can keep the first support surface 111 and the second support surface 120 always on the same plane. The first support surface 111 and the second support surface 121 are the ends facing the pet and continuously bear the weight from the pet. When the pet is standing, both the first support surface 111 and the second support surface 121 are subjected to the weight of the pet. Since both the first folding part 110 and the second folding part 120 are subjected to the weight of the pet, the force of gravity acting on the first folding part 110 is transmitted to the second folding part 120 through the first fulcrum 110b. The second support surface 121 is affected by the pet's weight. The pet's weight acts on the second support surface 121, and through the second support surface 121, it acts on the second fulcrum 120b, and through the second fulcrum 120b, it acts on the first folding part 110. This causes the first fulcrum 110b to abut against the second fulcrum 120, thus restricting the folding of the first folding part 110 relative to the second folding part 120. This ensures that the first support surface 111 and the second support surface 121 are on the same plane, providing better support for the pet. When the first support surface 111 and the second support surface 121 are on the same plane, the first fulcrum 110b abuts against the second fulcrum 120b, ensuring that the first support surface 111 and the second support surface 121 always remain on the same plane. When the pet stands on the pet mat folding board 100, it ensures that the pet is standing on the same horizontal plane, thus providing better support and preventing the pet's mood from being affected by poor support of the pet mat folding board 100.
[0050] It should be noted that the first folding part 110 is generally a rectangular plate, but in other embodiments it can be a plate of other shapes. The first fulcrum 110b is the abutment point and the point where the force exerted by the first folding part 110 on the second folding part 120 is applied.
[0051] The first support surface 111 is a flat plate.
[0052] The second fold 120 is generally a rectangular plate, but in other embodiments it can be a plate of other shapes. The second support surface 121 is a flat plate.
[0053] It should be noted that the first folding part 110 and the second folding part 120 are made of materials such as rigid plastic or rigid board.
[0054] When storing, the first folding part 110 is folded around the connection 100a between the first folding part 110 and the second folding part 120, so that the first folding part 110 is folded relative to the second folding part 120, thereby making the folded pet mat folding board 100 easy to store.
[0055] It should be noted that both the first connecting surface 112 and the second connecting surface 122 are flat plates and are made of flexible materials, such as adhesive cloth and flexible adhesive, so that the first folding part 110 and the second folding part 120 can be folded and unfolded relative to each other.
[0056] The first connecting surface 112 and the second connecting surface 122 are integrally formed. In this embodiment, the first connecting surface 112 and the second connecting surface 122 are connected, and the first supporting surface 111 is disposed away from the first connecting surface 112, and the second connecting surface 122 is disposed away from the second supporting part.
[0057] It should be further explained that in the manufacturing process of this pet mat folding board 100, a groove is first cut along the middle of one side plane of a complete board, and a joint (fold line) is formed on the other side, so that the groove divides the pet mat folding board into two parts, forming a first folding part 110 and a second folding part 120. At the same time, the first fulcrum 110b is located inside the side wall of the first folding part 110 located in the groove, and the second fulcrum 120b is located on the side wall of the second folding part 120 located in the groove. The first support surface 111 is located on the plane of the first folding part 110 along the direction of the groove opening, and the first connecting surface 112 is opposite to the plane on which the first support surface 111 is located. The second support surface 121 is located on the plane of the second folding part 120 along the direction of the groove opening, and the second connecting surface 122 is opposite to the plane on which the second support surface 121 is located.
[0058] Because the pet mat folding board is manufactured using a one-piece molding process, the manufacturing cost of the pet mat folding board is lower. During the manufacturing process, it is only necessary to cut a groove from one side (end face) of the complete rigid board to complete the manufacturing process, so that it can be folded and unfolded, making it convenient for storage, transportation, and use. When the first support surface and the second support surface are on the same plane, the first support point abuts against the second support point, which can keep the first support surface and the second support surface on the same plane.
[0059] In at least one embodiment of this application, a connection 100a is provided between the first connecting surface 112 and the second connecting surface 122. The connection 100a is provided with a crease line or a rotating member on the side away from the first supporting surface 111, so that the first folded portion 110 can be folded relative to the second folded portion 120.
[0060] Please refer to Figures 1-10In this embodiment, the first connecting surface 112 is rotatably connected to the second connecting surface 122 via a crease line, allowing the first connecting surface 112 to rotate relative to the second connecting surface 122 via the crease line, thereby enabling the first folding portion 110 to fold relative to the second folding portion 120. When unfolded for use, the first folding portion 110 is rotated via the crease line, causing the first folding portion 110 to rotate in the opposite direction relative to the second folding portion 120, thereby unfolding the first folding portion 110 relative to the second folding portion 120. When the first fulcrum 110b abuts against the second fulcrum 120b, the first folding portion 110 remains on the same plane relative to the second folding portion 120 to ensure the support of the pet mat folding board 100.
[0061] In another embodiment, the first connecting surface 112 is rotatably connected to the second connecting surface 122 via a rotating member, allowing the first connecting surface 112 to rotate relative to the second connecting surface 122 via the rotating member, thereby enabling the first folding portion 110 to fold relative to the second folding portion 120. When unfolded for use, the first folding portion 110 is rotated via the rotating member, causing the first folding portion 110 to rotate in the opposite direction relative to the second folding portion 120, thereby unfolding the first folding portion 110 relative to the second folding portion 120. When the first fulcrum 110b abuts against the second fulcrum 120b, the first folding portion 110 remains on the same plane relative to the second folding portion 120 to ensure the support of the pet mat folding board 100.
[0062] It should be noted that the rotating component is a hinge, a shaft, or other device that can rotate relative to the pivot.
[0063] In at least one embodiment of this application, the pet mat folding panel 100 further includes:
[0064] The reinforcement member 130 covers the crease line or the rotating member, and the reinforcement member 130 is disposed away from the first support surface 111.
[0065] Please refer to Figures 1-10 In this embodiment, by covering the crease line or rotating part with the reinforcement 130 and setting the reinforcement 130 away from the first support surface 111, the reinforcement 130 strengthens the connection 100a between the first folded part 110 and the second folded part 120, thereby improving the connection strength of the connection 100a. This ensures that the pet mat folding board 100 will not break or crack due to repeated folding after multiple folds, thus improving the service life of the connection 100a.
[0066] It should be noted that the reinforcement component 130 is made of materials such as adhesive tape, transparent adhesive, and adhesive layer, and is in the shape of a rectangular thin sheet.
[0067] In other embodiments, the first connecting surface 112 can be made of rigid plate or plastic, the second connecting surface 122 can be made of rigid plate or plastic, and the joint 100a between the first connecting surface 112 and the second connecting surface 122 can be connected by a flexible material.
[0068] In at least one embodiment of this application, the reinforcement 130 is made of a flexible material, and the reinforcement 130 undergoes flexible deformation when the first fold 110 is folded relative to the second fold 120.
[0069] Please refer to Figures 1-10 In this embodiment, since the reinforcement 130 is made of a flexible material, such as tape, transparent tape, or adhesive layer, when the first folding part 110 is folded relative to the second folding part 120, the reinforcement 130 can reinforce the connection 100a between the first folding part 110 and the second folding part 120 during the folding process, thereby preventing material damage or breakage at the connection 100a due to repeated folding and improving the service life of the pet mat folding board 100.
[0070] It should be further explained that, since the reinforcement 130 is located at the junction 100a between the first connecting surface 112 and the second connecting surface 122, and the reinforcement 130 is made of a flexible material, the reinforcement 130 can bend during the folding or unfolding of the first folding part 110 relative to the second folding part 120. During the folding or unfolding process, the reinforcement 130 can bend and deform during the rotation of the first folding part 110 relative to the second folding part 120 to adapt to the bending angle of the pet mat folding board 100. The reinforcement 130 will not hinder the unfolding or folding of the first folding part 110 relative to the second folding part 120, so that the pet mat folding board can be folded for storage and unfolded for use. During the unfolding and use of the pet mat folding board 100, the first fulcrum 110b and the second fulcrum 120b abut against each other so that the first support surface 111 and the second support surface 121 remain on the same horizontal plane, thereby ensuring that the pet can be better supported on the pet mat folding board.
[0071] In at least one embodiment of this application, the first folding portion 110 has a first abutting surface 110a on the side near the second folding portion 120, and the first fulcrum 110b is located on the first abutting surface 110a.
[0072] The second fold 120 has a second abutment surface 120a on the side near the first fold 110, and the second fulcrum 120b is located on the second fold surface.
[0073] Please refer to Figures 1-10 In this embodiment, when the first folding part 110 abuts against the second folding part 120, the first abutting surface 110a abuts against the second abutting surface 120a. Since the first fulcrum 110b is located on the first abutting surface 110a and the second fulcrum 120b is located on the second abutting surface 120a, the first supporting surface 111 and the second supporting surface 121 remain on the same plane. When a pet stands on the pet mat folding board 100, it can be ensured that the pet stands on the same horizontal plane, thereby providing better support and preventing the pet's mood from being affected by the poor support of the pet mat folding board 100.
[0074] The second abutting surface 120a is a plane, and the first abutting surface 110a is a plane. The first abutting surface 110a is used to abut against the second abutting surface 120a. Since α and β are complementary, when the first folded part 110 abuts against the second folded part 120, the force-bearing surface exists on the first abutting surface 110a and the second abutting surface 120a, so that the first folded part 110 and the second folded part 120 remain stable, and the first folded part 110 and the second folded part 120 remain on the same horizontal plane.
[0075] In at least one embodiment of this application, the first abutting surface 110a is connected to the first supporting surface 111, and the included angle between the first abutting surface 110a and the first supporting surface 111 is denoted as α.
[0076] The second abutting surface 120a is connected to the second supporting surface 121. The included angle between the second abutting surface 120a and the second supporting surface 121 is denoted as β, which satisfies the relationship α+β=180°.
[0077] Please refer to Figures 1-10 In this embodiment, when the first folding part 110 and the second folding part 120 are in place, the first folding part 110 rotates around the junction 100a between the first connecting surface 112 and the second connecting surface 122. After unfolding, the first abutting surface 110a abuts against the second abutting surface 120a. Since α and β are complementary, the unfolded first folding part 110 and the second folding part 120 are flush, the first supporting surface 111 and the second supporting part are flush, and the first connecting surface 112 and the second connecting surface 122 are flush. The pet stands on the first supporting surface 111 on the first folding part 110 and the second supporting part on the second folding part 120, which makes the levelness better, the pet can get better support, and the support effect is better.
[0078] In at least one embodiment of this application, 0 < α ≤ 90°. In at least one embodiment of this application, α = 90°.
[0079] Please refer to Figures 1-10In this embodiment, α is 90° and β is 90°, such that the first abutting surface 110a is perpendicular to the first supporting surface 111 and the second abutting surface 120a is perpendicular to the second supporting part. When the first abutting surface 110a abuts with the second abutting surface 120a, the abutting force of the first folding part 110 and the second folding part 120 acts on the first abutting surface 110a and the second abutting surface 120a, so that the first abutting surface 110a and the second abutting surface 120a can fit together to form a surface-to-surface abutment, thereby ensuring the flatness between the first folding part 110 and the second folding part 120, so that the flatness of the first folding part 110 and the second folding part 120 is higher after unfolding.
[0080] In another embodiment, 0° < α < 90°, forming an acute-angled triangular structure between the first abutting surface 110a and the first supporting surface 111, while 180° > β > 90°, forming an obtuse-angled triangular structure between the second abutting surface 120a and the second supporting part. These structures are more stable. When the first abutting surface 110a and the second abutting surface 120a abut, the contact area is larger due to the inclined surfaces abutting, allowing the abutting force to be dispersed, thus avoiding stress concentration. This ensures the flatness between the first folded part 110 and the second folded part 120 after unfolding and improves the service life of the pet mat folding board 100.
[0081] In at least one embodiment of this application, the pet mat folding board 100 is made of rigid plastic or cardboard material.
[0082] Please refer to Figures 1-10 In this embodiment, the pet mat folding board 100 is made of rigid plastic or cardboard material. The above materials can provide basic support for the pet mat folding board 100, so that the pet can be more stable when standing on the unfolded pet mat folding board 100 and will not get upset because its limbs are not on the same horizontal plane.
[0083] In at least one embodiment of this application, cavities 100b are formed between the first support surface 111 and the first connecting surface 112, and between the second support surface 121 and the second connecting surface 122.
[0084] The pet mat folding panel 100 also includes:
[0085] Multiple support frames 140 are equidistantly arranged within the cavity 100b.
[0086] In this embodiment, the support frame 140 between the first support surface 111 and the first connecting surface 112 and between the second support surface 121 and the second connecting surface 122 improves the strength and hardness between the first connecting surface 112 and the first support surface 111, and between the second connecting surface 122 and the second support surface 121, thereby providing better support force.
[0087] In this embodiment, the support capacity of the pet mat folding board 100 can be improved and a better support effect can be provided by multiple support frames 140 arranged at equal intervals.
[0088] It should be further explained that, because the first supporting surface 111 and the first connecting surface 112 are connected by a supporting frame 140, and a cavity structure is provided between the first supporting surface 111 and the first connecting surface 112, the weight of the first folding part 110 can be reduced, making it easier to transport and carry, and reducing manufacturing costs. Secondly, because the second supporting surface 121 and the second connecting surface 122 are connected by a supporting frame 140, and a cavity structure is provided between the second supporting surface 121 and the second connecting surface 122, the weight of the second folding part 120 can be reduced, making it easier to transport and carry, and reducing manufacturing costs.
[0089] In at least one embodiment of this application, the support frame 140 is elongated or curved.
[0090] In at least one embodiment of this application, the cross-section of the first support frame 140 is rectangular, arched, triangular, or circular.
[0091] Please refer to Figures 1-10 In this embodiment, a long strip-shaped support frame 140 can be used for support to improve the support effect of the pet mat folding board 100.
[0092] In another embodiment, a curved (e.g., arched) support frame 140 can be used for support to improve the support effect of the pet mat folding board 100.
[0093] In another embodiment, a triangular support frame 140 can be used to better form a stable triangular structure between the first connecting surface 112 and the first support surface 111, and between the second connecting surface 122 and the second support surface 121, thereby providing better support.
[0094] In another embodiment, a circular support frame 140 can be used to improve the support effect of the pet mat folding board 100.
[0095] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
