Description

A parallel account with secure use Technical Field

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

[0002] With the improvement of people's living standards, cars have become the most common means of transportation in daily life. The widespread use of cars has also provided convenience for more people who enjoy camping and picnicking. Common parallel tents on the market include a fixed shell, a rotating roller, a folding linkage, a connecting frame, and a tent fabric. The fixed shell is installed on the side of the car's luggage rack. The rotating roller is rotatably connected to the fixed shell. The folding linkage connects the fixed shell and the connecting frame. The tent fabric connects the rotating roller and the connecting frame. The fixed shell is equipped with an elastic device to provide rotational force to the rotating roller. The fixed shell also has a control device to cooperate with the rotating roller and control whether it stops rotating during its rotation. However, parallel tents on the market often lack a comprehensive control device. After the first operation, the locking effect of the control device on the rotating roller can be released, and the rotating roller can complete the entire process of rolling up the tarpaulin under the drive of the elastic device. However, during the continuous rolling up of the tarpaulin, the connecting frame continuously approaches the fixed shell while the folding linkage folds. If the folding linkage and connecting frame are about to collide with the human body and cause danger, it is difficult for the user to quickly use the control device to stop the rotating roller, resulting in low safety during use. In addition, the common folding connection is driven by a gas spring to unfold, and the unfolding process is too rapid. The folding linkage and connecting frame are prone to collide with the human body during unfolding, causing danger. How to design a parallel tent with higher safety is a technical problem that designers still need to solve. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes a safe parallel account, resolving the problem of low security during the use of parallel accounts.

[0004] The technical solution adopted by this utility model is as follows: a safe parallel tent, including a fixed shell, a rotating roller, a folding connecting rod, a connecting frame, and a tent fabric. The rotating roller is rotatably connected to the fixed shell, the folding connecting rod is connected between the fixed shell and the connecting frame, one end of the tent fabric is connected to the rotating roller, and the other end of the tent fabric is connected to the connecting frame. The fixed shell is provided with an elastic device for driving the rotating roller to rotate. An operating component is slidably connected to the fixed shell. The operating component includes a locking end. A first elastic element is connected to both the fixed shell and the operating component. A positioning seat is fixedly connected to the rotating roller, and a locking part is provided on the positioning seat. When the first elastic element forces the locking end to cooperate with the locking part, the rotating roller and the positioning seat are locked relative to the fixed shell.

[0005] With the above technical solution, when the user drives the operating component away from the positioning seat and disengages the locking end and locking part from each other, the elastic device releases its elasticity and drives the rotating roller to rotate and roll up the tarpaulin. During this process, the user needs to always hold the operating component and keep the locking end from contacting the locking part in order for the rotating roller to rotate continuously and roll up the tarpaulin smoothly. If it is observed that the folding linkage or connecting frame is about to hit the user, the user releases the operating component, and the first elastic component will automatically force the locking end and locking part to reconnect and stop the rotating roller from rotating, making it very safe to use. Throughout the entire process of rolling up the tarpaulin, the user can naturally observe the rolling of the tarpaulin and the movement of the folding linkage and connecting frame while holding the operating component, further improving the safety of the tarpaulin rolling process.

[0006] Furthermore, when the tarpaulin is rolled up, the rotation direction of the roller is the winding direction, and when the tarpaulin is spread out, the rotation direction of the roller is the spreading direction; a contact edge for abutting the locking end is provided on the periphery of the positioning seat, and points A and C are respectively provided at both ends of the contact edge. During the transition from point A to point C in the winding direction, the distance between the point on the contact edge and the rotation center of the positioning seat increases continuously or discontinuously, and the locking part is a stop section provided between point A and point C.

[0007] With the above technical solution, when the user drives the connecting frame and lays the tarpaulin outward, without the user applying any pulling force to the operating parts, the locking end gradually transitions from point A to point C when passing the contact edge, and falls directly from point C to point A when passing the stop section. That is, the locking end does not directly abut against the stop section and form a lock. The user does not need to control the operating parts when laying the tarpaulin, making it very convenient to use.

[0008] Furthermore, a point B is also provided on the contact edge. During the transition from point A to point B along the winding direction, the distance between the point on the contact edge and the rotation center of the positioning seat continuously increases; during the transition from point B to point C along the winding direction, the distance between the point on the contact edge and the rotation center of the positioning seat remains unchanged.

[0009] With the above technical solution, during the process of the user driving the connecting frame and spreading the tarpaulin outward, as the locking end transitions from point A to point B, the distance between the locking end and the rotation center of the positioning seat continuously increases and compresses the first elastic element, making the position change of the operating element more efficient. During the transition of the locking end from point B to point C, the distance between the locking end and the rotation center of the positioning seat remains unchanged, and the rotation process of the positioning seat and the rotating roller is very smooth.

[0010] Furthermore, the fixed shell includes an outer shell, a first partition, a second partition, a first fixing seat, and a second fixing seat. The first partition and the second partition are respectively disposed on both sides of the outer shell. The first fixing seat is fixedly connected to the first partition, and the second fixing seat is fixedly connected to the second partition. The first fixing seat is provided with a strip-shaped groove. The operating component includes a movable rod and a positioning block. The positioning block is connected to and fixed to the movable rod. The locking end is the end of the movable rod near the positioning seat. The positioning block is always slidably connected in the strip-shaped groove.

[0011] Through the above technical solution, the positioning block and the strip groove are stably connected, the movement of the movable rod and its upper locking end is standardized, and unnecessary work is avoided, resulting in higher efficiency.

[0012] Furthermore, the operating element also includes a gripping part, which is connected to the movable rod on the side opposite to the positioning seat.

[0013] The above technical solution makes it easier for users to grasp and control the operating components, resulting in a better user experience.

[0014] Furthermore, the bottom of the fixed shell is provided with a clearance opening for the movable rod to pass through, the movable rod is arranged vertically, and the locking end is the top end of the movable rod.

[0015] With the above technical solution, the user can pull down the gripping part to disengage the locking end and the locking part from each other. The parallel tent of this utility model is installed on the roof of the vehicle. The way of pulling down the gripping part is more in line with the human body's force usage habits, making it more labor-saving and providing a better user experience.

[0016] Furthermore, the first partition plate is provided with a first clearance hole, and the first fixed seat is provided with a first mounting hole; the second partition plate is provided with a second clearance hole, and the second fixed seat is provided with a second mounting hole; a connecting seat is fixedly provided on the rotating roller, a first bearing is provided between the positioning seat and the first mounting hole, and a second bearing is provided between the connecting seat and the second mounting hole.

[0017] The above technical solution makes the rotation process of the roller smoother by setting up the first and second bearings.

[0018] Furthermore, the elastic device is a torsion spring, one end of which is connected to the positioning seat, and the other end of which is connected to the second fixed seat.

[0019] Through the above technical solutions, torsion springs have the advantages of excellent elasticity and durability.

[0020] Furthermore, the folding linkage includes a first support rod and a second support rod rotatably connected to each other. A locking block and a driving block are slidably connected on the first support rod, and the sliding directions of the locking block and the driving block intersect. A snap-fit ​​groove is provided on the second support rod. A second elastic member is abutted between the locking block and the first support rod. The second elastic member is used to force the locking block to snap into the snap-fit ​​groove. A driven end is provided on the locking block, and an inclined surface is provided on the driving block. The inclined surface is used to push the driven end and disengage the locking block from the snap-fit ​​groove.

[0021] The above technical solution replaces the traditional gas spring structure with a locking block, a driving block, and a snap-fit ​​groove to keep the first and second support rods in the extended state. This avoids the parallel tent from extending too quickly and colliding with the user, thus improving safety. During the user's operation of the driving block's sliding motion, the inclined surface pushes the driven end and causes the locking block to disengage from the snap-fit ​​groove, releasing the first and second support rods from locking and restoring their rotational connection. The operation is very simple. When the first and second support rods are extended to a specified angle, the second elastic element causes the locking block to automatically snap into the snap-fit ​​groove, making it even more convenient to use.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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; the connector is provided with a sliding groove for placing a locking block, the sliding groove and the strip-shaped groove are connected by a clearance hole, the clearance hole allows 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, the cover plate covers the sliding groove.

[0027] With the above technical solution, the drive block can be installed by passing the first screw through the strip-shaped through hole and threading it onto the connector head. The installation of the drive block 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 effort. 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 alone.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0046] Referring to Figures 1-3, a safe parallel tent includes a fixed shell 1, a rotating roller 2, a folding link 3, a connecting frame 4, and a tent 5. The rotating roller 2 is rotatably connected to the fixed shell 1, the folding link 3 is connected between the fixed shell 1 and the connecting frame 4, one end of the tent 5 is connected to the rotating roller 2, and the other end of the tent 5 is connected to the connecting frame 4. The fixed shell 1 is provided with an elastic device for driving the rotating roller 2 to rotate. An operating member 6 is slidably connected to the fixed shell 1. The operating member 6 includes a locking end 601. A first elastic member 7 is connected to both the fixed shell 1 and the operating member 6. A positioning seat 8 is fixedly connected to the rotating roller 2. A locking part 802 is provided on the positioning seat 8. When the first elastic member 7 forces the locking end 601 to cooperate with the locking part 802, the rotating roller 2 and the positioning seat 8 are locked relative to the fixed shell 1.

[0047] When the user needs to drive the operating component 6 away from the positioning seat 8 and disengage the locking end 601 and the locking part 802, the elastic device releases its elasticity and drives the rotating roller 2 to rotate and roll up the tarpaulin 5. During this process, the user needs to always hold the operating component 6 and keep the locking end 601 from contacting the locking part 802 in order for the rotating roller 2 to rotate continuously and smoothly roll up the tarpaulin 5. If it is observed that the folding link 3 or the connecting frame 4 is about to hit the user, the user releases the operating component 6, and the first elastic component 7 will automatically force the locking end 601 and the locking part 802 to reconnect and stop the rotating roller 2 from rotating, making it very safe to use. During the entire process of rolling up the tarpaulin 5, the user will naturally observe the rolling of the tarpaulin 5 and the movement of the folding link 3 and the connecting frame 4 while holding the operating component 6, further improving the safety of the tarpaulin rolling process.

[0048] Referring to Figure 4, when the tarpaulin 5 is rolled up, the rotation direction of the roller 2 is the winding direction, and when the tarpaulin 5 is spread out, the rotation direction of the roller 2 is the spreading direction. The positioning seat 8 is provided with a contact edge 801 on its periphery for abutting the locking end 601. Points A 8011 and C 8013 are respectively provided at both ends of the contact edge 801. During the transition from point A 8011 to point C 8013 in the winding direction, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 increases continuously or discontinuously. The locking part 802 is a stop section provided between point A 8011 and point C 8013.

[0049] During the process of the user driving the connecting frame 4 and spreading the tarpaulin 5 outwards, without the user applying any pulling force to the operating component 6, the locking end 601 gradually transitions from point A 8011 to point C 8013 when passing the contact edge 801. When passing the stop section, it falls directly from point C 8013 to point A 8011. That is, the locking end 601 does not directly abut against the stop section and form a lock. The user does not need to control the operating component 6 during the process of spreading the tarpaulin 5, making it very convenient to use.

[0050] During the transition from point A 8011 to point C 8013 along the winding direction, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 continuously increases: this means that along this path, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 increases as the angle of that point relative to the rotation center of the positioning seat 8 changes.

[0051] During the transition from point A 8011 to point C 8013 along the winding direction, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 increases discontinuously: this means that along this path, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 increases or remains constant as the angle of the point relative to the rotation center of the positioning seat 8 changes; and in at least one segment of this path, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 increases as the angle of the point relative to the rotation center of the positioning seat 8 changes, and in at least one segment of this path, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 remains constant as the angle of the point relative to the rotation center of the positioning seat 8 changes.

[0052] In this invention, the distance between the contact point on the contact line 801 and the rotation center of the positioning seat 8 increases discontinuously during the transition from point A 8011 to point C 8013 along the winding direction. The specific change process is described later.

[0053] A point B 8012 is also provided on the contact edge 801. During the transition from point A 8011 to point B 8012 in the winding direction, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 increases continuously; during the transition from point B 8012 to point C 8013 in the winding direction, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 remains unchanged.

[0054] During the process of the user driving the connecting frame 4 and spreading the tarpaulin 5 outward, as the locking end 601 transitions from point A 8011 to point B 8012, the distance between the locking end 601 and the rotation center of the positioning seat 8 continuously increases and compresses the first elastic element 7, making the position change of the operating element 6 more efficient. During the transition of the locking end 601 from point B 8012 to point C 8013, the distance between the locking end 601 and the rotation center of the positioning seat 8 remains unchanged, and the rotation process of the positioning seat 8 and the rotating roller 2 is very smooth.

[0055] During the transition from point A 8011 to point B 8012 along the winding direction, the distance between the point on the contact edge 801 and the rotation center of the positioning seat 8 increases linearly. The contact edge 801 between point A 8011 and point B 8012 is set in an arc shape, and the transition at point B 8012 is smooth. This makes the path of the locking end 601 between point A 8011 and point B 8012, as well as at point B 8012, smoother and more convenient to use.

[0056] It should be noted that the purpose of points A 8011, B 8012, and C 8013 is to indicate the specific position of the point relative to the rotation center of the positioning seat 8 in the circumferential direction, and not to indicate the position of the point in the axial direction of the positioning seat 8.

[0057] Referring to Figures 3-5, the fixed shell 1 includes an outer shell 101, a first partition 102, a second partition 103, a first fixing seat 104, and a second fixing seat 105. The first partition 102 and the second partition 103 are respectively disposed on both sides of the outer shell 101. The first fixing seat 104 is fixedly connected to the first partition 102, and the second fixing seat 105 is fixedly connected to the second partition 103. A strip-shaped sliding groove 1041 is provided on the first fixing seat 104. The operating component 6 includes a movable rod 602 and a positioning block 603. The positioning block 603 is connected to and fixed to the movable rod 602. The locking end 601 is the end of the movable rod 602 near the positioning seat 8. The positioning block 603 is always slidably connected in the strip-shaped sliding groove 1041.

[0058] The stable connection between the positioning block 603 and the strip groove 1041 regulates the movement of the movable rod 602 and its upper locking end 601, avoiding unnecessary work and making the use more efficient.

[0059] The first elastic element 7 is a spring sleeved on the movable rod 602.

[0060] Referring to Figure 3, the operating component 6 also includes a gripping part 604, which is connected to the side of the movable rod 602 opposite to the positioning seat 8.

[0061] The gripping part 604 makes it more convenient for users to grasp and control the operating part 6, resulting in a better user experience.

[0062] The gripping part 604 can be configured as a handle, a pull strap or a pull ring, and the gripping part 604 is preferably a pull ring in this utility model.

[0063] The bottom of the fixed housing 1 is provided with a clearance opening 110 for the movable rod 602 to pass through. The movable rod 602 is arranged vertically, and the locking end 601 is the top of the movable rod 602.

[0064] The user can pull down the gripping part 604 to disengage the locking end 601 and the locking part 802 from each other. The parallel tent of this utility model is installed on the roof of the vehicle. The way of pulling down the gripping part 604 is more in line with the human body's force usage habits, making it easier to use and providing a better experience.

[0065] Referring to Figure 5, the first partition 102 is provided with a first clearance hole 106, and the first fixed seat 104 is provided with a first mounting hole 108; the second partition 103 is provided with a second clearance hole 107, and the second fixed seat 105 is provided with a second mounting hole 109; a connecting seat 9 is fixedly provided on the roller 2, a first bearing 11 is provided between the positioning seat 8 and the first mounting hole 108, and a second bearing 12 is provided between the connecting seat 9 and the second mounting hole 109.

[0066] The arrangement of the first bearing 11 and the second bearing 12 makes the rotation process of the roller 2 smoother.

[0067] Both the first bearing 11 and the second bearing 12 are preferably self-lubricating bearings. Specifically, both the first bearing 11 and the second bearing 12 are copper bearings.

[0068] The elastic device is a torsion spring 10, one end of which is connected to the positioning seat 8, and the other end of which is connected to the second fixed seat 105.

[0069] Torsion spring 10 has the advantages of excellent elasticity and durability.

[0070] Referring to Figures 6-9, the folding linkage 3 includes a first support rod 301 and a second support rod 302 that are rotatably connected to each other. A locking block 303 and a driving block 304 are slidably connected on the first support rod 301. The sliding directions of the locking block 303 and the driving block 304 intersect. A snap-fit ​​groove 3021 is provided on the second support rod 302. A second elastic element 305 is abutting between the locking block 303 and the first support rod 301. The second elastic element 305 is used to force the locking block 303 to snap into the snap-fit ​​groove 3021. A driven end 3031 is provided on the locking block 303. An inclined surface 3041 is provided on the driving block 304. The inclined surface 3041 is used to push the driven end 3031 and disengage the locking block 303 from the snap-fit ​​groove 3021.

[0071] The traditional gas spring structure is replaced by a locking block 303, a driving block 304, and a locking groove 3021 to keep the first support rod 301 and the second support rod 302 in the unfolded state. This avoids the parallel tent from unfolding too quickly and colliding with the user during use, thus improving safety. When the user operates the driving block 304 to slide, the inclined surface 3041 can push the driven end 3031 and drive the locking block 303 to disengage from the locking groove 3021, so that the first support rod 301 and the second support rod 302 are unlocked and restored to the rotating connection state, making the operation very simple. When the first support rod 301 and the second support rod 302 are unfolded to a specified angle, the second elastic element 305 causes the locking block 303 to automatically engage with the locking groove 3021, making it more convenient to use.

[0072] The second elastic element 305 is preferably a spring.

[0073] Referring to Figures 7 and 8, a columnar surface 3022 is provided on the end of the second support rod 302. The columnar surface 3022 is connected to the snap-fit ​​groove 3021. When the locking block 303 and the snap-fit ​​groove 3021 are disengaged, the locking block 303 abuts against the columnar surface 3022.

[0074] When the first support rod 301 and the second support rod 302 rotate relative to each other, the locking block 303 slides on the surface of the cylindrical surface 3022, making the relative rotation process of the first support rod 301 and the second support rod 302 smoother.

[0075] The drive block 304 is provided with a gripping part 3042, which is separate from the first support rod 301, and the inclined surface 3041 is inclined towards the gripping part 3042.

[0076] The gripping part 3042 makes it more convenient for the user to hold the drive block 304. The user can pull the drive block 304 to drive the driven end 3031 by using the inclined surface 3041, which is more in line with the human body's force usage habits.

[0077] Referring to Figures 8, 10, and 11, this utility model also includes a first screw 306. The first support rod 301 includes a rod 3011 and a connector 3012 that are fixedly connected. The connector 3012 is provided with a strip-shaped groove 3013. The driving block 304 is placed in the strip-shaped groove 3013. The driving block 304 is provided with a strip-shaped through hole 3043. The first screw 306 passes through the strip-shaped through hole 3043 and is threadedly connected to the connector 3012. The strip-shaped groove 3013 and the strip-shaped through hole 3043 are connected to the connector 3012. The through holes 3043 extend in the same direction; the connector 3012 is provided with a groove 3014 for accommodating the locking block 303, and a clearance hole 3015 is provided between the groove 3014 and the strip groove 3013, through which the driven end 3031 passes; the present invention also includes a cover plate 307 and a second screw 308, the second screw 308 passes through the cover plate 307 and is threadedly connected to the connector 3012, and the cover plate 307 covers the groove 3014.

[0078] The first screw 306 passes through the strip-shaped through hole 3043 and is threaded onto the connector 3012 to install the drive block 304, making the installation of the drive block 304 very convenient. The drive block 304 is limited to the inner wall of the strip-shaped groove 3013 and the end of the first screw 306, and the sliding connection is very stable. The length of the strip-shaped through hole 3043 limits the stroke of the drive block 304, avoiding unnecessary work. When the locking block 303 is placed in the slide groove 3014, the driven end 3031 is also placed in the clearance hole 3015. Then, the cover plate 307 is fixedly connected to the connector 3012 using the second screw 308 to complete the installation of the locking block 303 and prevent the locking block 303 from detaching alone.

[0079] When the tarpaulin 5 of the parallel tent of this utility model needs to be laid out, the user drives the connecting frame 4 to gradually move away from the fixed shell 1. During this process, the folding connecting rod 3 unfolds, the rotating roller 2 and the positioning seat 8 rotate along the laying direction and lay out the tarpaulin 5. The user does not need to control the operating part 6. The locking end 601 contacts the relative contact and slides along 801 in the winding direction and passes through multiple turns.

[0080] During the relative rotation of the first support rod 301 and the second support rod 302, the locking block 303 slides on the surface of the columnar surface 3022 until the locking block 303 is aligned with the locking groove 3021. Under the action of the second elastic element 305, the locking block 303 automatically engages with the locking groove 3021, thereby achieving angular locking of the first support rod 301 and the second support rod 302.

[0081] When the parallel tent of this utility model needs to roll up the tarpaulin 5, the user first needs to grasp the gripping part 3042 and pull the drive block 304. The inclined surface 3041 can push the driven end 3031 and drive the locking block 303 to disengage from the snap-fit ​​groove 3021, so that the first support rod 301 and the second support rod 302 are unlocked and restored to the rotating connection state. Then, the user needs to always grasp the gripping part 604 and keep the locking end 601 from contacting the stop section so that the roller 2 can rotate continuously and roll up the tarpaulin 5 smoothly. If it is observed that the folding link 3 or the connecting frame 4 is about to hit the human body, the user releases the gripping part 604. The first elastic element 7 will automatically force the locking end 601 to move upward and contact the stop section to stop the roller 2 from rotating.

[0082] 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.
