Description

Technical Field

[0001] This utility model relates to the field of car-side tents, and in particular to a parallel tent. Background Technology

[0002] As people's living standards continue to improve, cars have become a common means of transportation for families, and they also facilitate outdoor picnics and camping for more people who enjoy road trips. A car-side tent is a tent that is installed on the side of a car to provide shade and create a resting area for people.

[0003] Reference application number 202222713885.2, entitled "A Support Structure for a Car-Side Tent," includes a mounting base and a tent fabric. The mounting base also has support rods for supporting the tent fabric, and a roll for rewinding the tent fabric is rotatably mounted on the mounting base. The support rods include a first support rod and a second support rod rotatably connected. The first support rod is rotatably connected to the mounting base, one end of the tent fabric is connected to the roll, and the other end of the tent fabric has a connecting rod. The second support rod is rotatably connected to the connecting rod. The first and second support rods can be flipped and folded towards the mounting base. A gas spring is installed between the first support rod and the mounting base. The gas spring drives the first support rod and the mounting base to unfold relative to each other, thereby causing the first and second support rods to rotate relative to each other and moving the connecting rod away from the roll. However, this structure, when opened, provides excessive elasticity from the gas spring, which can easily cause the user to bump into it, making it unsafe to use. Furthermore, the high cost of the gas spring increases the overall cost of the car-side tent. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a parallel tent, which solves the issues of insufficient safety during use and high production costs.

[0005] The technical solution adopted by this utility model is as follows: a parallel tent, including an outer shell, a tarpaulin, a winding mechanism, folding support rods, and a connecting frame. The winding mechanism includes a rotating roller rotatably connected inside the outer shell. One end of the tarpaulin is connected to the rotating roller, and the other end of the tarpaulin is connected to the connecting frame. One end of the folding support rod is rotatably connected to the outer shell, and the other end of the folding support rod is rotatably connected to the connecting frame. The folding support rod includes a first support rod and a second support rod rotatably connected to each other. A locking device is provided on the first support rod and / or the second support rod, which can lock the first support rod and the second support rod after they are unfolded.

[0006] With the above technical solution, when the user opens the parallel tent, the connecting frame needs to be driven away from the outer shell. During this process, the first and second support rods unfold and the tent fabric is laid out. The locking device can keep the first and second support rods in the unfolded state. This avoids the parallel tent from unfolding too quickly and colliding with people during use, thus improving safety. The locking device design replaces the gas spring, which greatly reduces production costs.

[0007] Furthermore, the locking device includes a locking block, a driving block, and a locking groove. The locking block and the driving block are both slidably connected to the first support rod. The sliding direction of the locking block intersects the sliding direction of the driving block. The locking groove is disposed on the second support rod. An elastic element is abutting between the locking block and the first support rod. The elastic element is used to force the locking block to engage with the locking groove. The locking block is provided with a driven end, and the driving block is provided with an inclined surface. The inclined surface is used to push the driven end and disengage the locking block from the locking groove.

[0008] With the above technical solution, during the user's operation of the sliding of the drive block, the inclined surface can push the driven end and drive the locking block to disengage from the slot, so that the first support rod and the second support rod are unlocked and restored to the rotating connection state, making the operation very simple; when the first support rod and the second support rod are extended to the specified angle, the elastic element causes the locking block to automatically engage with the slot, making it more convenient to use.

[0009] Furthermore, a first point and a second point are provided on both ends of the inclined surface. When the locking block is inserted into the snap-fit ​​groove, the first point is closer to the snap-fit ​​groove than the second point. A stop surface is connected at the first point, and the stop surface faces one side of the inclined surface.

[0010] The above technical solution makes the position of the driven end more stable when the locking block and the locking slot are engaged, avoiding the need for the drive block to slide more during the unlocking process of the locking block and the locking slot, thus making the use of the drive block more efficient.

[0011] Furthermore, a columnar surface is provided on the end of the second support rod, the columnar surface is connected to the snap-fit ​​groove, and the locking block abuts against the columnar surface when the locking block is disengaged from the snap-fit ​​groove.

[0012] With the above technical solution, when the first support rod and the second support rod rotate relative to each other, the locking block slides on the cylindrical surface, making the relative rotation process of the first support rod and the second support rod smoother.

[0013] Furthermore, the drive block is provided with a gripping part, which is separate from the first support rod, and the inclined surface faces the gripping part.

[0014] The above technical solution makes it more convenient for the user to hold the drive block. The user can pull the drive block and use the inclined surface to drive the driven end, which is more in line with the human body's force usage habits.

[0015] Furthermore, it also includes a first screw, the first support rod includes a fixedly connected rod and a connector, the connector is provided with a strip-shaped groove, the drive block is placed in the strip-shaped groove, the drive block is provided with a strip-shaped through hole, the first screw passes through the strip-shaped through hole and is threadedly connected to the connector, the strip-shaped groove and the strip-shaped through hole extend in the same direction.

[0016] With the above technical solution, the first screw can be threaded through the strip-shaped through hole and connected to the connector head to realize the installation of the drive block, which is very convenient. The drive block is limited between the inner wall of the strip-shaped groove and the end of the first screw, and the sliding connection is very stable. The length of the strip-shaped through hole limits the stroke of the drive block, avoiding wasted work.

[0017] Furthermore, the connector head is provided with a groove for accommodating the locking block, and an clearance hole is provided between the groove and the strip groove for the driven end to pass through; it also includes a cover plate and a second screw, the second screw passes through the cover plate and is threadedly connected to the connector head, and the cover plate covers the groove.

[0018] With the above technical solution, when the locking block is placed in the slide groove, the driven end is also placed in the clearance hole. Then, the cover plate is fixedly connected to the connector head by the second screw to complete the installation of the locking block and prevent the locking block from falling off by itself.

[0019] Furthermore, the connector head is provided with a first hinge plate, and the second support rod is provided with a second hinge plate. There are two second hinge plates, and the two second hinge plates are attached to both sides of the first hinge plate. It also includes a vertical rotating shaft, which passes through the first hinge plate and the second hinge plate.

[0020] The above technical solution makes the connection between the first support rod and the second support rod more stable and secure.

[0021] Furthermore, the winding mechanism also includes a torsion spring, one end of which is connected to the rotating roller, and the other end of which is fixed to the outer casing.

[0022] The above technical solution results in a simple winding mechanism and a torsion spring with advantages of durability and high elasticity. Attached Figure Description

[0038] See Figure 1 , 2 A parallel tent includes an outer shell 1, a tarpaulin 2, a winding mechanism, folding support rods, and a connecting frame 3. The winding mechanism includes a rotating roller 4 rotatably connected inside the outer shell 1. One end of the tarpaulin 2 is connected to the rotating roller 4, and the other end of the tarpaulin 2 is connected to the connecting frame 3. One end of the folding support rod is rotatably connected to the outer shell 1, and the other end of the folding support rod is rotatably connected to the connecting frame 3. The folding support rod includes a first support rod 5 and a second support rod 6 rotatably connected to each other. A locking device is provided on the first support rod 5 and / or the second support rod 6, which can lock the first support rod 5 and the second support rod 6 after they are unfolded.

[0039] When opening the parallel tent, the user needs to drive the connecting frame 3 away from the outer shell 1. During this process, the first support rod 5 and the second support rod 6 unfold each other and the tent fabric 2 is laid out. The locking device can keep the first support rod 5 and the second support rod 6 in the unfolded state. During use, the parallel tent is prevented from unfolding too quickly and colliding with the human body, which makes the safety higher. The design of the locking device replaces the gas spring, which greatly reduces the production cost.

[0040] In this invention, during the process of the first support rod 5 and the second support rod 6 being extended to their respective limits, the angle through which the first support rod 5 and the second support rod 6 rotate is less than 180°. When the first support rod 5 and the second support rod 6 are extended to their respective limits, an obtuse angle is formed between the first support rod 5 and the second support rod 6, so that the winding mechanism can roll up the tarpaulin 2 while driving the first support rod 5 and the second support rod 6 to fold together.

[0041] The preferred number of folding support rods is two. The two folding support rods are connected to both sides of the outer shell 1. The outer shell 1, the two folding support rods and the connecting frame 3 form a frame shape, so that the tarpaulin 2 is more stably supported after being laid out.

[0042] See Figures 1-5 The locking device includes a locking block 7, a driving block 8, and a locking groove 601. The locking block 7 and the driving block 8 are slidably connected to the first support rod 5. The sliding direction of the locking block 7 intersects the sliding direction of the driving block 8. The locking groove 601 is provided on the second support rod 6. An elastic element 9 is abutting between the locking block 7 and the first support rod 5. The elastic element 9 is used to force the locking block 7 to engage with the locking groove 601. The locking block 7 is provided with a driven end 10, and the driving block 8 is provided with an inclined surface 801. The inclined surface 801 is used to push the driven end 10 and disengage the locking block 7 from the locking groove 601.

[0043] During the user's operation of the sliding of the drive block 8, the inclined surface 801 can push the driven end 10 and drive the locking block 7 to disengage from the slot 601, so that the first support rod 5 and the second support rod 6 are unlocked and restored to the rotating connection state, making the operation very simple; when the first support rod 5 and the second support rod 6 are extended to the specified angle, the elastic element 9 causes the locking block 7 to automatically engage with the slot 601, making it more convenient to use.

[0044] Preferably, the sliding direction of the locking block 7 and the sliding direction of the driving block 8 are perpendicular to each other in space.

[0045] The elastic element 9 is preferably a spring.

[0046] See Figure 5 The inclined surface 801 has a first point 8011 and a second point 8012 at both ends. When the locking block 7 is inserted into the snap-fit ​​groove 601, the first point 8011 is closer to the snap-fit ​​groove 601 than the second point 8012. A stop surface 802 is connected at the first point 8011, and the stop surface 802 faces the inclined surface 801.

[0047] This makes the position of the driven end 10 more stable when the locking block 7 and the locking slot 601 are engaged, avoiding the need for the drive block 8 to slide more during the unlocking process of the locking block 7 and the locking slot 601, thus making the use of the drive block 8 more efficient.

[0048] The second support rod 6 has a columnar surface 602 at its end, which is connected to the snap-fit ​​groove 601. When the locking block 7 and the snap-fit ​​groove 601 are disengaged, the locking block 7 abuts against the columnar surface 602.

[0049] When the first support rod 5 and the second support rod 6 rotate relative to each other, the locking block 7 slides on the surface of the cylindrical surface 602, making the relative rotation process of the first support rod 5 and the second support rod 6 smoother.

[0050] The drive block 8 is provided with a gripping part 803, which is separate from the first support rod 5, and the inclined surface 801 is inclined towards the gripping part 803.

[0051] The gripping part 803 makes it more convenient for the user to hold the drive block 8. The user can pull the drive block 8 to drive the driven end 10 by using the inclined surface 801, which is more in line with the human body's force usage habits.

[0052] Preferably, the gripping part 803 is located on the end of the drive block 8 away from the first support rod 5 and is plate-shaped, making it more convenient and secure for the human hand to grip.

[0053] See Figures 4-7 The present invention also includes a first screw 11, and a first support rod 5 including a rod 501 and a connector 502 that are fixedly connected. The connector 502 is provided with a strip groove 5021, and a drive block 8 is placed in the strip groove 5021. The drive block 8 is provided with a strip through hole 804. The first screw 11 passes through the strip through hole 804 and is threadedly connected to the connector 502. The strip groove 5021 and the strip through hole 804 extend in the same direction.

[0054] The first screw 11 passes through the strip-shaped through hole 804 and is threaded onto the connector 502 to install the drive block 8, which is very convenient. The drive block 8 is limited to the inner wall of the strip-shaped groove 5021 and the end of the first screw 11, and the sliding connection is very stable. The length of the strip-shaped through hole 804 limits the stroke of the drive block 8, avoiding unnecessary work.

[0055] It should be noted that after the first screw 11 is installed, the head of the first screw 11 does not press against the drive block 8; otherwise, the drive block 8 would not be able to slide.

[0056] See Figures 4-7 The connector 502 has a groove 5022 for accommodating the locking block 7. A clearance hole 5023 is provided between the groove 5022 and the strip groove 5021, through which the driven end 10 passes. It also includes a cover plate 12 and a second screw 13, which passes through the cover plate 12 and is threadedly connected to the connector 502. The cover plate 12 covers the groove 5022.

[0057] When the locking block 7 is placed in the slide groove 5022, the driven end 10 is also placed in the clearance hole 5023. Then, the cover plate 12 is fixedly connected to the connector 502 by the second screw 13 to complete the installation of the locking block 7 and prevent the locking block 7 from falling off by itself.

[0058] Preferably, there are two second screws 13, which are located on both sides of the slide groove 5022.

[0059] The connector 502 is provided with a first hinge plate 5024, and the second support rod 6 is provided with a second hinge plate 603. There are two second hinge plates 603, and the two second hinge plates 603 are attached to both sides of the first hinge plate 5024. It also includes a vertical rotating shaft 14, which passes through the first hinge plate 5024 and the second hinge plate 603.

[0060] This makes the connection between the first support rod 5 and the second support rod 6 more stable and secure.

[0061] Preferably, the cylindrical surface 602 is disposed on the periphery of the second hinge plate 603.

[0062] See Figure 8 The winding mechanism also includes a torsion spring 15, one end of which is connected to the roller 4, and the other end of which is fixed to the outer shell 1.

[0063] The winding mechanism has a simple structure, and the torsion spring 15 has the advantages of being durable and having high elasticity.

[0064] When the parallel tent of this utility model needs to be unfolded, the connecting frame 3 is pulled and gradually moved away from the outer shell 1. During this process, the first support rod 5 and the second support rod 6 unfold relative to each other, and the locking block 7 slides on the surface of the columnar surface 602. When the first support rod 5 and the second support rod 6 unfold to the specified angle, the locking block 7 aligns with the snap-fit ​​groove 601 and automatically snaps into the snap-fit ​​groove 601 under the drive of the elastic member 9. At this time, the angle of the first support rod 5 and the second support rod 6 is locked.

[0065] When the parallel tent of this utility model needs to be rolled up, the drive block 8 needs to be pulled first, so that the inclined surface 801 on the drive block 8 pushes the driven end 10 and drives the locking block 7 to disengage from the snap-fit ​​groove 601. After the elasticity of the torsion spring 15 is released, during the process of the roller 4 rolling up the tent 2, the first support rod 5 and the second support rod 6 fold relative to each other.

[0066] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
