Description

Technical Field

[0001] This utility model relates to the field of motorhome accessories technology, specifically to a folding table structure for motorhomes. Background Technology

[0002] With changing modern lifestyles, the popularity of motorhomes continues to grow. Motorhomes offer a convenient and comfortable way for people to feel at home while traveling. These vehicles are typically equipped with a kitchen, bathroom, and seating area, making them an ideal mobile accommodation option. Since these vehicles often have limited interior space, interior design is crucial to meet diverse needs such as working, dining, resting, and entertainment. The design of the in-vehicle table plays a vital role, needing to fulfill multiple functions while minimizing its space occupation when not in use to ensure sufficient room for movement.

[0003] Existing technologies have led to some folding table designs that utilize sliding grooves and hinge mechanisms. These designs open and close the table by setting grooves on the side panels and sliding support components within them, in conjunction with the hinge mechanism. Compared to traditional mechanical connection methods, this type of design is simpler and can effectively reduce product manufacturing costs while improving ease of use and stability. However, when the table is placed horizontally, the distribution of support force in its structure is not uniform enough, which may cause the support components to be subjected to greater mechanical stress, thereby affecting the overall strength and durability of the table and reducing its service life. Therefore, improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a folding table structure for a motorhome to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: a folding table structure for a motorhome includes a mounting base, side plates on both sides of the mounting base, a first sliding groove on the side plate, a support component slidably disposed in the first sliding groove, a fixed shaft fixedly connected between the side plates, a hinge rotatably connected to the fixed shaft, a table body fixedly connected to the hinge, a tension spring between the support component and the fixed shaft, and the support component and the hinge are used together to support the table body to be placed horizontally.

[0006] Preferably, the support assembly includes a movable rod that slides within a first groove, the two ends of the tension spring being connected to a fixed shaft and the movable rod respectively, the movable rod being provided with a connector, the connector being provided with a support plate, and the hinge being provided with a first limiting groove and a second limiting groove that match the movable rod.

[0007] Preferably, the first limiting groove and the fixed shaft are on the same horizontal plane, and the second limiting groove and the fixed shaft are on the same vertical plane.

[0008] Preferably, a second sliding groove is provided on the side plate, and positioning pins are provided on both sides of the support plate, with the positioning pins slidably disposed in the second sliding groove.

[0009] Preferably, the first slide groove is vertically arranged, and the second slide groove is inclined.

[0010] This utility model has the following beneficial effects:

[0011] 1. The folding table structure for this RV involves installing the mounting base on a designated base on the inner side wall of the RV. When the table is in the unfolded state, it rotates around a fixed axis to a horizontal position. The support component rises along the first slide groove under the tension of the tension spring and locks the table in place with the hinge, providing support. When the table is in the folded state, after the limit is released, the support component slides down under gravity or the spring, and the table rotates around the fixed axis to fold up. The support component and the hinge work together to distribute the load evenly, improving the structural strength. The tension spring helps reduce resistance when unfolding and folding the table and provides elasticity for support, improving the overall strength and durability of the table and extending its service life.

[0012] 2. The support assembly includes a movable rod that slides within the first groove. Two ends of a tension spring are connected to a fixed shaft and the movable rod, respectively. A connector is mounted on the movable rod, and a support plate is mounted on the connector. A hinge has a first limiting groove and a second limiting groove that match the movable rod. When the table is unfolded, the movable rod rises with the support assembly and enters the second limiting groove of the hinge for vertical limiting. When the table is folded, the movable rod enters the first limiting groove of the hinge for horizontal limiting, restricting excessive rotation of the table. The two limiting grooves fix the movable rod in the horizontal and vertical directions respectively, ensuring the stability of the table when unfolded and folded.

[0013] 3. A second sliding groove is provided on the side plate, and positioning pins are provided on both sides of the support plate. The positioning pins are slidably set in the second sliding groove. The first sliding groove is set vertically, and the second sliding groove is set at an angle. The support plate slides in the second sliding groove through the positioning pin, which is linked with the movement of the movable rod. The angled design of the second sliding groove guides the support plate to move along a specific trajectory, enhancing the stability of the support. The first and second sliding grooves together constrain the movement of the support component and prevent shaking. The large contact area between the positioning pin and the sliding groove reduces local stress concentration. At the same time, the angled second sliding groove reduces sliding resistance, making the unfolding or folding process of the table smoother. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0022] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0023] Example 1:

[0024] A folding table structure for a motorhome includes a mounting base 1, side plates 2 on both sides of the mounting base 1, a first sliding groove 3 on the side plate 2, a support component 4 slidably disposed in the first sliding groove 3, a fixed shaft 5 fixedly connected between the side plates 2, a hinge 6 rotatably connected to the fixed shaft 5, a table body 7 fixedly connected to the hinge 6, and a tension spring 8 between the support component 4 and the fixed shaft 5. The support component 4 and the hinge 6 work together to support the table body 7 in a horizontal position.

[0025] In practical use of this structure, the mounting base 1 is installed on the designated base on the inner side wall of the RV. When the table 7 is in the unfolded state, the table 7 rotates around the fixed axis 5 to a horizontal position. The support component 4 rises along the first slide groove 3 under the tension of the tension spring 8 and locks the table 7 through cooperation with the hinge 6, providing support. When the table 7 is in the folded state, after the limit is released, the support component 4 slides down under the action of gravity or spring, and the table 7 rotates around the fixed axis 5 to fold up. Through the coordinated force of the support component 4 and the hinge 6, the load on the table 7 is evenly distributed, improving the structural strength. The tension spring 8 helps to reduce the resistance when unfolding and folding the table 7 and provides elasticity to achieve a supporting effect, improving the strength and durability of the entire table 7 and extending its service life.

[0026] It should be noted that the base has a certain thickness, so after the structure is installed, when the table 7 is unfolded or folded, the side wall of the hinge 6 will not contact the inner side wall of the RV when it rotates around the fixed axis 5.

[0027] In this embodiment, the support assembly 4 includes a movable rod 41 that slides within the first slide groove 3. The two ends of the tension spring 8 are respectively connected to the fixed shaft 5 and the movable rod 41. The movable rod 41 is provided with a connector 42, and the connector 42 is provided with a support plate 43. The hinge 6 has a first limiting groove 44 and a second limiting groove 45 that match the movable rod 41. When the table body 7 is unfolded, the movable rod 41 rises with the support assembly 4 and enters the second limiting groove 45 of the hinge 6 for vertical limiting. When the table body 7 is folded, the movable rod 41 enters the first limiting groove 44 of the hinge 6 for horizontal limiting, restricting the table body 7 from excessive rotation. The movable rod 41 is fixed in the horizontal and vertical directions by the two limiting grooves respectively, ensuring the stability of the table body 7 when unfolded and folded.

[0028] In this embodiment, the first limiting groove 44 and the fixed shaft 5 are on the same horizontal plane, and the second limiting groove 45 and the fixed shaft 5 are on the same vertical plane. That is, when the movable rod 41 is located in the first limiting groove 44, the table body 7 is in a folded state, and when the movable rod 41 is located in the second limiting groove 45, the table body 7 is in an unfolded state. Through the spatial positional relationship between the limiting groove and the fixed shaft 5, the angular accuracy of the table body 7 when unfolded or folded is ensured. The positional design of the two limiting grooves prevents the table body 7 from locking in an unexpected position and avoids misoperation.

[0029] In this embodiment, a second slide groove 9 is provided on the side plate 2, and positioning pins 10 are provided on both sides of the support plate 43. The positioning pins 10 are slidably disposed in the second slide groove 9. The first slide groove 3 is vertically disposed, and the second slide groove 9 is inclinedly disposed. The support plate 43 slides in the second slide groove 9 through the positioning pins 10, forming a linkage with the movement of the movable rod 41. The inclined design of the second slide groove 9 guides the support plate 43 to move along a specific trajectory, enhancing the support stability. The first slide groove 3 and the second slide groove 9 together constrain the movement of the support assembly 4, preventing swaying. The large contact area between the positioning pins 10 and the slide groove reduces local stress concentration. At the same time, the inclined second slide groove 9 reduces sliding resistance, making the unfolding or folding process of the table body 7 smoother.

[0030] The working principle of this utility model is as follows: A folding table structure for a motorhome. Specifically, when using this structure, the mounting base 1 is installed on a designated base on the inner wall of the motorhome. When the table 7 is in the unfolded state, it rotates around the fixed axis 5 to a horizontal position. The support component 4 rises along the first slide groove 3 under the tension of the tension spring 8, locking the table 7 through cooperation with the hinge 6, providing support. When the table 7 is in the folded state, after the limit is released, the support component 4 slides down under gravity or the spring, and the table 7 rotates around the fixed axis 5 to fold up. Through the coordinated force distribution of the support component 4 and the hinge 6, the load on the table 7 is evenly distributed, improving structural strength. The tension spring 8 helps reduce resistance when unfolding and folding the table 7 and provides elasticity for support, thus improving the overall strength of the table 7. To enhance strength and durability and extend service life, the support assembly 4 includes a movable rod 41 that slides within the first groove 3. The ends of the tension spring 8 are connected to the fixed shaft 5 and the movable rod 41, respectively. A connector 42 is provided on the movable rod 41, and a support plate 43 is provided on the connector 42. The hinge 6 has a first limiting groove 44 and a second limiting groove 45 that match the movable rod 41. When the table 7 is unfolded, the movable rod 41 rises with the support assembly 4 and enters the second limiting groove 45 of the hinge 6 for vertical limiting. When the table 7 is folded, the movable rod 41 enters the first limiting groove 44 of the hinge 6 for horizontal limiting, restricting excessive rotation of the table 7. The two limiting grooves fix the movable rod 41 in the horizontal and vertical directions, respectively, ensuring the stability of the table 7 during unfolding and folding.

[0031] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
