Furthermore, the movable plates 420 are rotatably mounted within the mounting groove 410 via shafts, allowing users to manually rotate the movable plates 420 to switch the displayed content, further enhancing the interactivity and fun of the park benches.

[0041] In another possible embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the frame 100 is specifically composed of a keel assembly 110 and a decorative panel 120. The keel assembly 110 is the main supporting skeletal structure, and the seat panel 200, back panel 300, and viewing panel 400 are fixedly mounted on the keel assembly 110. The decorative panel 120 serves to decorate and enhance aesthetics. The decorative panel 120 covers the upper side of the keel assembly 110 (the upper side being the easily observable surface). In actual installation, the decorative panel 120 is cut out corresponding to the positions of the seat panel 200, back panel 300, and viewing panel 400, forming a cutout around the seat panel 200. 0. The backrest panel 300 and the viewing panel 400 are recessed into the hollowed-out parts of the decorative panel 120 during actual installation, forming an integrated assembly structure with the seat panel 200, backrest panel 300 and viewing panel 400. The decorative panel 120 is made of metal and has the function of protecting the sides of the seat panel 200, backrest panel 300 and viewing panel 400. At the same time, the sides of the decorative panel 120 are flush with the sides of the seat panel 200, backrest panel 300 and viewing panel 400 to ensure the overall aesthetics of the park seats.

[0042] In actual settings, such as Figure 3 As shown, the decorative panel 120 is smoothly set along a predetermined arc at the connection points between the seat panel 200 and the backrest panel 300, and at the connection points between the backrest panel 300 and the viewing panel 400. This predetermined arc not only enhances the aesthetics of the park bench but also effectively prevents users from bumping into things while moving around the edges of the bench, thus improving safety. Furthermore, this smooth connection design facilitates the drainage of rainwater, preventing corrosion caused by water accumulation and extending the bench's lifespan. During the actual installation of the seat panel 200, backrest panel 300, and viewing panel 400, the arc-shaped parts of the viewing panel 400 should also be assembled at corresponding angles to ensure the stability and aesthetics of the viewing panel 400 installation. Since the seat panel 200 and backrest panel 300 are the parts that users directly contact, the surface treatment of these panels is also crucial. In this embodiment, both the seat panel 200 and backrest panel 300 have anti-slip textures to increase friction when users sit or lie down, preventing slippage and improving safety. Meanwhile, the seat panel 200 and back panel 300 also adopt an ergonomic design, with their curved surfaces conforming to the user's body contours, providing a more comfortable sitting or lying experience.

[0043] In another possible embodiment of this utility model, such as Figure 2 and Figure 4As shown, the seat panel 200 and backrest panel 300 each include a plurality of support plates 210. These support plates 210 are laid along the length of the frame 100 on the keel assembly 110 and connected to the back of the support plates 210 with screws. Adjacent support plates 210 are evenly spaced at predetermined intervals to reduce overall weight while ensuring structural strength, and to facilitate drainage and ventilation, reducing moisture and corrosion problems. The support plates 210 can be made of wood or plastic to ensure user comfort.

[0044] In another possible embodiment of this utility model, such as Figure 3 As shown, to further improve the aesthetics of the park bench and prevent the internal frame assembly 110 from being exposed, decorative side panels 130 are provided at both ends of the frame assembly 110 in this embodiment. The decorative side panels 130 have several decorative holes 131. These holes not only serve an aesthetic purpose but also effectively reduce the weight of the side panels 130. Furthermore, the holes 131 facilitate ventilation, reducing moisture and corrosion inside the bench. The side of the decorative side panel 130 abuts against the corresponding side of the decorative panel 120, completely covering the frame assembly 110 and enhancing the overall aesthetics and structural stability of the bench. In addition, the connection between the decorative side panel 130 and the decorative panel 120 also features a smooth transition design, specifically, the side of the decorative side panel 130 abuts against the corresponding side of the decorative panel 120. This design prevents users from bumping into each other during activity, improving safety.

[0045] In the above embodiments, such as Figure 4 As shown, the aforementioned keel assembly 110 includes several support piles 111. The support piles 111 are load-bearing components, serving to connect the ground to the park bench as a whole. In actual installation, a base 114 is provided at the bottom of each support pile 111, and the bases 114 on the several support piles 111 are located on the same horizontal plane. During actual installation, the bases 114 are used to correspond with the ground, thus cooperating with the installation structure on the ground to achieve a limiting and fixing effect. In a specific embodiment, the base 114 also includes vertical angle steels 115 disposed on opposite sides. The vertical angle steels 115 increase the contact area between the base 114 and the ground, thereby improving the stability of the park bench placement; on the other hand, they can connect with the installation structure on the ground to achieve a fixed position.

[0046] Furthermore, in one specific embodiment, during the installation phase of the park bench, pre-embedded sleeves 116 can be embedded in the concrete ground where the park bench will be installed. In this embodiment, the aforementioned vertical angle steel 115 is provided with mounting holes. After the park bench is placed in the position corresponding to the pre-embedded sleeve 116, it can be connected to the pre-embedded sleeve 116 by bolts 117 passing through the mounting holes, thereby achieving a stable connection between the park bench and the ground. In addition, the setting of the pre-embedded sleeves 116 can also play a limiting role for the park bench, preventing it from shifting in the horizontal direction, further improving the stability of the park bench. In actual installation, the appropriate number and position of pre-embedded sleeves 116 can be selected according to the specific ground conditions and the design requirements of the park bench to achieve the best fixing effect. At the same time, the embedding depth of the pre-embedded sleeves 116 should also be reasonably designed according to the bearing capacity of the ground and the weight of the park bench to ensure that it can withstand various loads generated by the park bench during use.

[0047] Furthermore, in another possible embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the aforementioned keel assembly 110 also includes several horizontal connecting rods 112 and several inclined connecting rods 113. The several horizontal connecting rods 112 are fixedly connected to the support piles 111 at corresponding positions. In actual installation, the horizontal connecting rods 112 and inclined connecting rods 113 are adapted to the design arc of the park seats. The seat panel 200, the back panel 300, and the viewing panel 400 are fixedly mounted on the horizontal connecting rods 112 and inclined connecting rods 113.

[0048] Based on the above structural design, the frame 100 is designed not only for functionality but also for aesthetics and durability. Specifically, the frame 100 includes a keel assembly 110, which serves as the main support structure to ensure the overall stability of the park bench. The keel assembly 110 consists of components such as support piles 111, horizontal connecting rods 112, and inclined connecting rods 113. Through reasonable layout and connection, these components enable the frame 100 to withstand loads from different directions, ensuring the safe use of the bench. The support piles 111, as load-bearing components, have a base 114 at their bottom. The vertical angle steel 115 on the base 114 further enhances the contact area and stability with the ground. During actual installation, the base 114 is firmly connected to the concrete ground using pre-embedded sleeves 116 and bolts 117, thereby achieving the fixed installation of the park bench.

[0049] In another possible embodiment of this utility model, such as Figure 5 and Figure 6As shown, since park benches are typically located in public spaces and are needed at night, and to prevent users from bumping into them due to poor visibility, this embodiment also includes a bracket 530 on the bottom edge of the seat panel 200 and the viewing panel 400. A light strip 531 is embedded inside the bracket 530. The circuit of the light strip 531 is housed within the horizontal connecting rod 112 and the support post 111, and connected to a pre-installed power supply structure on the ground. This allows for the switching control and power supply of the light strip 531. At night or in low-light conditions, users can control the light strip 531 to illuminate it. The light emitted by the light strip 531 illuminates the surrounding area of ​​the seat panel 200 and the viewing panel 400, making it easier for users to identify the location of the benches and avoid collisions. It also enhances the nighttime visual effect of the benches, improving their practicality and aesthetics. Furthermore, the light strip 531 adds a warm atmosphere to the park environment, enhancing the overall user experience.

[0050] In another possible embodiment of this utility model, such as Figure 5 and Figure 6 As shown, to further improve the aesthetic appearance of the park seats and avoid glare from the light strip 531 when turned on, a first skirt 510 is provided on the side of the seat panel 200 opposite to the backrest panel 300, and a second skirt 520 is provided on the side of the viewing panel 400 opposite to the backrest panel 300. The first skirt 510 and the second skirt 520 are arranged vertically. In this embodiment, the card holder 530 is located on the first skirt 510 and the second skirt 520, specifically on the inner side of the first skirt 510 and the second skirt 520. When the light strip 531 is turned on, the light shines towards the ground. The first skirt 510 and the second skirt 520 can block the light, preventing the light from directly shining into the user's eyes and causing discomfort. The first skirt 510 and the second skirt 520 can also protect the edges of the seat panel 200 and the viewing panel 400, preventing edge damage due to bumps and extending the service life of the seats. Meanwhile, the design of the first skirt 510 and the second skirt 520 also adds to the sense of layering of the seat, making it look more aesthetically pleasing overall. In addition, the first skirt 510 and the second skirt 520 can also serve as decorative elements, using different colors, materials, or patterns to coordinate with the overall style of the seat and further enhance its visual appeal.

[0051] Based on the above embodiments, the effects of using the park benches provided by this utility model are as follows:

[0052] Firstly, the park bench, by combining a seat panel 200, a backrest panel 300, and a viewing panel 400, not only provides basic rest functions but also adds information viewing capabilities, making the bench more functionally diverse.
