An expandable seat based on a hunting vehicle

Abstract

This invention relates to the technical field of hunting vehicles, and more particularly to an expandable seat based on a hunting vehicle. The seat includes a hunting vehicle, a sliding mechanism on the inner surface of the base, a flipping mechanism on the upper surface of the base, and a folding mechanism on one side surface of the hunting vehicle. This expandable seat, based on a hunting vehicle, utilizes the folding mechanism. In use, lifting the panel disengages the positioning hole from the positioning block, rotating the second folding plate allows the connecting block to insert into the connecting slot and secure it, then rotating the first and second folding plates parallel to the panel, pulling the anti-slip block compresses the return spring of the hook plate, releasing it to lock the hook, and then folding the panel around the hunting vehicle's connection point to create space for storing items and equipment. When a person is seated, the operation is reversed: first, rotate the panel parallel to the ground, pull the hook plate, rotate the second folding plate, and insert the positioning hole into the positioning block to secure it. At this point, the panel can be used as a seat, flexibly utilizing space and converting functions.

Technical Field

[0001] This invention relates to the field of hunting vehicle technology, and in particular to an expandable seat based on a hunting vehicle. Background Technology

[0002] A hunting vehicle is a mode of transportation used for hunting. Hunters often use hunting vehicles to facilitate the search and pursuit of prey due to the relatively complex natural environment in the wild. Traditional hunting vehicle seats are fixed in structure and cannot be flexibly adjusted in position and shape. During the hunting process, various equipment such as hunting tools and prey storage devices are often needed. The types and quantities of equipment required vary depending on the hunting task and scenario. Therefore, there is a particular need for an expandable seat based on the hunting vehicle.

[0003] However, existing hunting vehicles have seats installed in a fixed structure inside the vehicle. Hunting vehicles with fixed seats cannot flexibly adjust the interior space layout according to the amount and size of the equipment. When carrying a lot of large equipment, the interior space is difficult to make reasonable use of because the seats cannot be moved or adjusted, which makes it difficult to place the equipment and may even affect driving safety and vehicle performance.

[0017] Compared with the prior art, the beneficial effects of this invention are as follows: This expandable seat based on a hunting vehicle, through the setting of a sliding mechanism and a flipping mechanism, allows the backrest to be in a comfortable angle with the seat during daily use. At this time, the flipping spring is in a naturally extended state, pushing the locking rod so that part of it is located in the through hole of the flipping block. When it is necessary to flip the backrest, press the button, and the button will drive the locking rod to move in the direction of compressing the flipping spring, so that the locking rod gradually slides out of the through hole of the flipping block. During this process, the vertical rod slides along the moving groove, and the connecting rod plays the role of transmitting force and maintaining the overall stability of the locking rod's movement. Once the locking rod is completely disengaged from the through hole, the fixed connection between the backrest and the seat is released. At this time, the backrest can be flipped around the rotational connection point between the seat and the backrest. The backrest drives the flipping block to rotate within the range allowed by the flipping groove, realizing the folding of the backrest and better releasing space. Then, release the button, and the flipping spring loses its rotation. After pressing, the elastic potential energy is released, pushing the locking lever back towards the flipping block, awaiting the next adjustment. When the position needs adjustment, pull the handle, causing the connecting plate to move upwards. The connecting plate then moves the connecting block and the fixing block. The fixing block slides within the sliding groove, overcoming the elastic force of the fixing spring. The limit rod can limit the connecting block, making the sliding of the connecting block and the fixing block more stable. At this time, the fixing block disengages from its current fixing slot, releasing the engagement with the base plate. Then, the base can be pushed, allowing the slider on the lower surface of the base to slide along the slide rail. When the seat is pushed to the desired position, release the handle. The fixing spring loses external pressure and begins to release elastic potential energy. The fixing spring pushes the fixing block towards the base plate. Under the push of the spring, the fixing block engages in the corresponding fixing slot, fixing the seat in the new position. This allows for flexible adjustment of the interior space layout according to the amount and size of equipment, making reasonable use of the interior space. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-4 The present invention provides a technical solution: an expandable seat based on a hunting vehicle, including a hunting vehicle 1, a roof 2 fixedly connected to the upper surface of the hunting vehicle 1, a base plate 3 fixedly connected to the lower surface of the hunting vehicle 1, a slide rail 4 provided on the upper surface of the base plate 3, a slider 5 slidably connected to the upper surface of the slide rail 4, a base 6 fixedly connected to the upper surface of the slider 5, a sliding mechanism 7 provided on the inner surface of the base 6, a flipping mechanism 8 provided on the upper surface of the base 6, and a folding mechanism 9 provided on one side surface of the hunting vehicle 1;

[0030] The sliding mechanism 7 includes a sliding groove 701, a limiting rod 702, a fixing spring 703, a fixing block 704, a connecting block 705, a connecting plate 706, a handle 707, and a fixing slot 708. The inner surface of the base 6 has a sliding groove 701. The limiting rod 702 is fixedly connected to the inner surface of the sliding groove 701. A fixing spring 703 is fixedly connected to the inner surface of the sliding groove 701. One end of the fixing spring 703 is fixedly connected to a fixing block 704. One end of the fixing block 704... A connecting block 705 is fixedly connected to the side surface of the base plate 3. A connecting plate 706 is fixedly connected to one side surface of the connecting block 705. A handle 707 is fixedly connected to the upper surface of the connecting plate 706. A fixing slot 708 is provided on the upper surface of the base plate 3. Through the arrangement of the sliding groove 701, the limiting rod 702, the fixing spring 703, the fixing block 704, the connecting block 705, the connecting plate 706, the handle 707, and the fixing slot 708, when in use, pulling the handle 707 will drive the connecting plate 706. Moving upwards, the connecting plate 706 drives the connecting block 705 and the fixing block 704 to move. The fixing block 704 slides within the sliding groove 701, overcoming the elastic force of the fixing spring 703. The limiting rod 702 can limit the connecting block 705, making the sliding of the connecting block 705 and the fixing block 704 more stable. At this time, the fixing block 704 disengages from its current fixing slot 708, releasing its engagement with the base plate 3. Then, the base 6 can be pushed, allowing the slider 5 on the lower surface of the base 6 to slide along the slide rail 4. When the seat 801 is pushed to the desired position, the handle 707 is released, and the fixing spring 703 loses external pressure and begins to release its elastic potential energy. The fixing spring 703 pushes the fixing block 704 towards the base plate 3. Under the push of the spring, the fixing block 704 engages in the corresponding fixing slot 708, thus fixing the seat 801 in the new position. This allows for flexible adjustment of the interior space layout according to the amount and size of equipment, enabling reasonable utilization of the interior space.

[0031] The folding mechanism 9 includes a panel 901, a first folding plate 903, and a second folding plate 905. The panel 901 and the hunting vehicle 1 are folded along the rotation axis of the vehicle width axis. The first folding plate 903 and the panel 901 are folded along the rotation axis of the vehicle width axis. The second folding plate 905 and the first folding plate 903 are folded along the rotation axis of the vehicle length axis.

[0032] Furthermore, multiple sets of slide rails 4 are provided on the surface of the base plate 3, and multiple sets of base 6 are provided. Through the arrangement of slide rails 4, multiple sets of slide rails 4 are distributed on the surface of the base plate 3 during use, so that the force on various parts of the base plate 3 is more even during the sliding process of the seat 801.

[0033] Furthermore, the limiting rod 702 passes through the connecting block 705, and the fixing springs 703 are distributed in multiple sets at equal intervals on the upper surface of the fixing block 704. With the setting of the limiting rod 702, when an external force is applied to the handle 707 and drives the connecting block 705 to move, the connecting block 705 slides along the axial direction of the limiting rod 702. This ensures that the connecting block 705 and the fixed block 704 connected to it can move along a predetermined straight trajectory without deviation or misalignment.

[0034] Furthermore, the connecting block 705 is symmetrically arranged with respect to the central axis of the fixing block 704. The inner wall size of the fixing slot 708 matches the outer wall size of the fixing block 704. Through the arrangement of the fixing slot 708 and the fixing block 704, when the fixing block 704 is inserted into the fixing slot 708 during use, the matching of the two sizes allows the fixing block 704 to be tightly fitted into the fixing slot 708, thereby achieving a secure lock on the seat 801.

[0035] Furthermore, the flipping mechanism 8 includes a seat 801, a backrest 802, a flipping block 803, a through hole 804, a locking rod 805, a push plate 806, a vertical rod 807, a connecting rod 808, a flipping spring 809, a rod groove 810, a moving groove 811, and a flipping groove 812. The seat 801 is fixedly connected to the upper surface of the base 6. The backrest 802 is rotatably connected to one side surface of the seat 801. The flipping block 803 is fixedly connected to one side surface of the backrest 802. The flipping block 803 has a through hole 804. The locking rod 805 is slidably connected to the inner surface of the through hole 804. One end of the locking rod 805 is fixedly connected to... A vertical rod 807 is fixedly connected to the outer surface of the pressing plate 806 and the locking rod 805. A connecting rod 808 is fixedly connected to the outer surface of the vertical rod 807. A flip spring 809 is fixedly connected to one end of the locking rod 805. A rod groove 810 is formed on the surface of the locking rod 805. A moving groove 811 is formed on the lower surface of the base 6. A flip groove 812 is formed on one side surface of the base 6. The seat 801, backrest 802, flip block 803, through hole 804, locking rod 805, pressing plate 806, vertical rod 807, connecting rod 808, flip spring 809, rod groove 810, moving groove 811, and flip groove 812 are connected to the base 6. In configuration 2, during daily use, the chair back 802 is positioned at a comfortable angle to the seat 801. At this time, the flip spring 809 is in a naturally extended state, pushing the locking rod 805 so that part of it is positioned within the through hole 804 of the flip block 803. When it is necessary to flip the chair back 802, press the button 806. The button 806 moves the locking rod 805 in the direction of compressing the flip spring 809, causing the locking rod 805 to gradually slide out of the through hole 804 of the flip block 803. During this process, the vertical rod 807 slides along the moving groove 811, and the connecting rod 808 transmits force and retains the locking rod 805. The overall motion stability is achieved when the locking rod 805 is completely disengaged from the through hole 804, and the fixed connection between the backrest 802 and the seat 801 is released. At this time, the backrest 802 can be flipped around the rotation connection point between the seat 801 and the backrest 802. The backrest 802 drives the flipping block 803 to rotate within the range allowed by the flipping groove 812, thereby folding the backrest 802 and freeing up more space. Then, the button 806 is released, and the flipping spring 809 loses its pressing force and begins to release its elastic potential energy, pushing the locking rod 805 to move back towards the flipping block 803, waiting for the next adjustment.

[0036] Furthermore, the flip block 803 is symmetrically arranged around the central axis of the chair back 802. The inner wall size of the through hole 804 matches the outer wall size of the locking rod 805. Through the arrangement of the through hole 804, the locking rod 805 can be tightly inserted into the through hole 804 during use, with minimal gap between them. This ensures that the chair back 802 will not loosen or wobble in the locked state, maintaining a stable angle and position, and providing reliable support for the user.

[0037] Furthermore, two sets of rod grooves 810 are provided on the surface of the engaging rod 805, and multiple sets of moving grooves 811 are provided on the lower surface of the base 6. Through the setting of the moving grooves 811, multiple sets of moving grooves 811 provide a track for the vertical rod 807 during use. The design of the moving grooves 811 enables the vertical rod 807 to move linearly in a predetermined direction, keeping synchronized with the movement of the engaging rod 805, and ensuring the coordination of the entire operation process.

[0038] Furthermore, the folding mechanism 9 includes a panel 901, a hook 902, a first folding plate 903, a connecting block 904, a second folding plate 905, a connecting slot 906, a connecting seat 907, a positioning hole 908, a parts slot 909, a limiting post 910, a hook plate 911, a return spring 912, an anti-slip block 913, a positioning groove 914, and a positioning block 915. The panel 901 is rotatably connected to one side surface of the hunting vehicle 1. The hook 902 is fixedly connected to the lower surface of the panel 901. The first folding plate 903 is rotatably connected to the lower surface of the panel 901. A connecting block 904 is fixedly connected to one side surface of the first folding plate 903. The second folding plate 905 is rotatably connected to one side surface of the first folding plate 903. A connecting slot 906 is provided on the side surface. A connecting seat 907 is fixedly connected to the lower surface of the second folding plate 905. A positioning hole 908 is provided on one side surface of the connecting seat 907. A parts groove 909 is provided on the inner surface of the first folding plate 903. A limit post 910 is fixedly connected to the inner surface of the parts groove 909. A hook plate 911 is slidably connected to the outer surface of the limit post 910. A return spring 912 is fixedly connected to one side surface of the hook plate 911. An anti-slip block 913 is fixedly connected to the lower surface of the hook plate 911. A positioning groove 914 is provided on the upper surface of the base plate 3. A positioning block 915 is fixedly connected to the upper surface of the positioning groove 914. The connection is achieved through the panel 901, hook 902, first folding plate 903, connecting block 904, and second folding plate 905. The panel 905, connecting slot 906, connecting seat 907, positioning hole 908, parts slot 909, limiting post 910, hook plate 911, return spring 912, anti-slip block 913, positioning groove 914, and positioning block 915 are configured so that, in use, the panel 901 is lifted upwards, allowing the positioning hole 908 on the surface of the connecting seat 907 to move out of the positioning block 915 on the surface of the positioning groove 914. Then, the second folding plate 905 rotates around its connection point with the first folding plate 903. At this time, the connecting block 904 on the first folding plate 903 is inserted into the connecting slot 906 on the second folding plate 905, thus fixing the connection between the first folding plate 903 and the second folding plate 905. Then, the first folding plate 903 and the second folding plate 905 rotate around... Rotating around the connection point with panel 901, the anti-slip block 913 is pulled, causing hook plate 911 to compress return spring 912 and move within parts slot 909. Simultaneously, limiting post 910 limits the movement of hook plate 911, making its movement more stable. Then, the first folding plate 903 and second folding plate 905 are aligned parallel to panel 901. The anti-slip block 913 is then released, and return spring 912 rebounds, pushing hook plate 911 back to its original position. At this point, hook plate 911 engages with hook 902, fixing the first folding plate 903 and second folding plate 905 to the surface of panel 901. Then, panel 901 is rotated around the connection point of the hunting vehicle 1, folding panel 901 to free up more space for storing items and equipment. If seating is required, further storage is possible.First, rotate panel 901 to be parallel to the hunting vehicle 1. Then, pull hook plate 911 to release the first folding plate 903 and the second folding plate 905. Next, rotate the second folding plate 905 out of the first folding plate 903. Finally, insert positioning hole 908 into positioning block 915 to fix connecting seat 907. Panel 901 can then be used as a seat.

[0039] Furthermore, the hooks 902 are symmetrically arranged around the central axis of the panel 901, and the outer wall size of the connector 907 matches the inner wall size of the positioning groove 914. Through the arrangement of the hooks 902, the two sets of hooks 902 can ensure balanced force during use, and will not tilt or twist due to force on one side, thus ensuring a tight fit and stable connection with the connecting parts.

[0040] Furthermore, two sets of limiting posts 910 are provided on the inner surface of the part groove 909, and the return springs 912 are symmetrically arranged with respect to the central axis of the hook plate 911. By setting the limiting posts 910, the limiting posts 910 can limit the movement range of the hook plate 911 during use, preventing it from moving excessively and causing interference with other components. At the same time, it also limits the degree of compression of the return springs 912, avoiding damage to the return springs 912 due to excessive compression.

[0041] Working principle: Lift the panel 901 upwards, allowing the positioning hole 908 on the surface of the connecting seat 907 to move out of the positioning block 915 on the surface of the positioning groove 914. Then, the second folding plate 905 rotates around its connection point with the first folding plate 903. At this time, the connecting clip 904 on the first folding plate 903 is inserted into the connecting clip slot 906 on the second folding plate 905, thus fixing the connection between the first folding plate 903 and the second folding plate 905. Then, the first folding plate 903 and the second folding plate 905 rotate around their connection point with the panel 901, pulling the anti-slip block 913, causing the hook plate 911 to compress the return spring 912 and move within the parts groove 909. At the same time, the limiting post 910 limits the movement of the hook plate 911. To achieve greater stability, align the first folding plate 903 and the second folding plate 905 parallel to the panel 901. Then, release the anti-slip block 913, causing the return spring 912 to spring back and push the hook plate 911 back to its original position. At this point, the hook plate 911 will engage the hook 902, fixing the first folding plate 903 and the second folding plate 905 to the surface of the panel 901. Then, rotate the panel 901 around the connection point of the hunting vehicle 1 to fold it, freeing up more space for storing items and equipment. If someone needs to sit on it, first rotate the panel 901 to be parallel to the hunting vehicle 1, then pull the hook plate 911 to release the first folding plate 903 and the second folding plate 905. Next, rotate the second folding plate 905 out of the first folding plate 903. Finally, place the positioning hole 908 into place. In the positioning block 915, the connecting seat 907 is fixed, and the panel 901 can then be used as a seat. During daily use, the backrest 802 is at a comfortable angle to the seat 801. At this time, the flip spring 809 is in a naturally extended state, pushing the locking rod 805 so that part of it is located within the through hole 804 of the flip block 803. When it is necessary to flip the backrest 802, press the button 806. The button 806 drives the locking rod 805 to move in the direction of compressing the flip spring 809, causing the locking rod 805 to gradually slide out of the through hole 804 of the flip block 803. During this process, the vertical rod 807 slides along the moving groove 811. The connecting rod 808 plays a role in transmitting force and maintaining the overall stability of the locking rod 805's movement. With the locking rod 805 completely disengaged from the through hole 804, the fixed connection between the backrest 802 and the seat 801 is released. At this point, the backrest 802 can be flipped around the rotational connection point between the seat 801 and the backrest 802. The backrest 802 drives the flipping block 803 to rotate within the range allowed by the flipping groove 812, achieving the folding of the backrest 802 and freeing up more space. Then, the button plate 806 is released, and the flipping spring 809, having lost its pressing force, begins to release its elastic potential energy, pushing the locking rod 805 back towards the flipping block 803, awaiting the next adjustment. When the position needs to be adjusted, the handle 707 is pulled, causing the connecting plate 706 to move upward. The connecting plate 706 then moves the connecting block 705 and the fixing block 704.The fixing block 704 slides within the sliding groove 701, overcoming the elastic force of the fixing spring 703. The limiting rod 702 can limit the connecting block 705, making the sliding of the connecting block 705 and the fixing block 704 more stable. At this time, the fixing block 704 disengages from its current fixing groove 708, releasing its engagement with the base plate 3. Then, the base 6 can be pushed, allowing the slider 5 on the lower surface of the base 6 to slide along the slide rail 4. When the seat 801 is pushed to the desired position, the handle 707 is released, and the fixing spring 703 loses external pressure and begins to release its elastic potential energy. The fixing spring 703 pushes the fixing block 704 towards the base plate 3. Under the push of the spring, the fixing block 704 engages in the corresponding fixing groove 708, thus fixing the seat 801 in the new position. This allows for flexible adjustment of the interior space layout according to the amount and size of equipment, enabling rational utilization of the interior space.
