Description

Area of ​​the utility model

[0001] The present utility model relates to the technical field of car-side tents, in particular to a parallel tent with safety in use. State of the art

[0002] With the improvement in people's living standards, cars have become the most common means of transportation in daily life. The popularity of cars also offers greater convenience to more people who enjoy camping and picnicking.The standard parallel tent on the market comprises a mounting bracket, a swivel caster, a folding frame, a connecting frame, and a tarpaulin, wherein the mounting bracket is designed for installation on the side of the car's luggage rack, wherein the swivel caster is rotatably connected to the mounting bracket, wherein the folding frame is connected between the mounting bracket and the connecting frame, wherein the tarpaulin is connected between the swivel caster and the connecting frame, wherein an elastic means for providing a rotational force to the swivel caster is arranged on the mounting bracket, wherein a control device is arranged on the mounting bracket which interacts with the use of the swivel caster and controls whether the rotation is stopped or not during its rotation.After a single operation of the control device by the commercially available parallel tent, the locking effect of the control device on the rotating roller can be released, allowing the complete winding of the tarpaulin by the rotating roller to be carried out under the drive of the elastic device. However, during continuous winding of the tarpaulin, the connecting frame folds continuously near the mounting bracket while the folding poles fold simultaneously. If, during the movement of the folding poles and connecting frame, they are close to colliding with the human body and causing a hazard, it is difficult for the user to quickly operate the control device to stop the movement of the rotating roller, thus compromising the safety of the operating process. Additionally, the standard folding mechanism is driven by gas springs for unfolding.Because the unfolding process is too fast, the folding poles and connecting frame tend to bump into the human body, creating hazards during the unfolding process. Designing a parallel tent with greater safety is a technical problem that designers still need to solve. Purpose of the utility model

[0003] To solve the aforementioned problems, the present utility model provides a parallel tent with safety in use, thereby solving the problem of the parallel tent's low safety during use.

[0004] The technical solution according to the present utility model consists of a parallel tent with safety in use, comprising a mounting bracket, a swivel roller, a folding frame, a connecting frame and a tarpaulin, wherein the swivel roller is rotatably connected to the mounting bracket, wherein the folding frame is connected between the mounting bracket and the connecting frame, wherein one end of the tarpaulin is connected to the swivel roller and the other end of the tarpaulin is connected to the connecting frame, wherein an elastic means for driving the rotation of the swivel roller is arranged on the mounting bracket, wherein an actuating element is slidably connected to the mounting bracket, wherein the actuating element has a locking end, wherein a first elastic element is connected together with the mounting bracket and the actuating element, and wherein a positioning seat is fixedly connected to the swivel roller.wherein a locking section is arranged at the positioning seat, wherein the rotary roller and the positioning seat are locked relative to the mounting shell when the locking end is forced by the first elastic element to cooperate with the locking section.

[0005] The above technical solution requires the user to move the actuating element away from the positioning seat, separating the locking end and the locking section. The elastic release of the elastic mechanism then drives the rotation of the roller to wind up the tarpaulin. During this process, the user must always hold the actuating element and keep the locking end out of contact with the locking section to ensure the roller rotates continuously and winds up the tarpaulin smoothly. If the folding rod or connecting frame is about to strike the user, the user releases the actuating element manually.The first elastic element automatically forces the locking end and locking section to re-engage and connect, stopping the rotation of the roller and ensuring safe operation. Throughout the entire tarpaulin winding process, the user naturally monitors the winding status of the tarpaulin and the movements of the folding rod and connecting frame while maintaining a grip on the operating element, further enhancing safety during winding.

[0006] Furthermore, it is provided that the direction of rotation of the rotary roller when winding the tarpaulin is the winding direction, wherein the direction of rotation of the rotary roller when unwinding the tarpaulin is the unwinding direction, wherein a contact flank for contact with the locking end is arranged on the circumferential side of the positioning seat, wherein an A-point and a C-point are arranged at both ends of the contact flank, wherein during the transition from the A-point to the C-point in the winding direction, the distance of the point on the contact flank from the center of rotation of the positioning seat increases continuously or discontinuously, wherein the locking section is a stop section arranged between the A-point and the C-point.

[0007] With the above technical solution, the connecting frame is driven by the user to unwind the tarpaulin. If the user does not apply any pulling force to the actuator, the locking end gradually moves from point A to point C as it passes the contact edge, and then drops directly from point C to point A as it passes the stop section. This means the locking end does not directly contact the stop section to form a lock. There is no need for the user to control the actuator while the tarpaulin is unwinding, making it very convenient to use.

[0008] Furthermore, it is provided that a B-point is arranged on the contact flank, wherein during the transition from the A-point to the B-point in the winding direction the distance of the point on the contact flank from the center of rotation of the positioning seat continuously increases, wherein during the transition from the B-point to the C-point in the winding direction the distance of the point on the contact flank from the center of rotation of the positioning seat remains unchanged.

[0009] The above technical solution allows the user to drive the connecting frame to unwind the tarpaulin. During the transition of the locking end from point A to point B, the distance of the locking end from the pivot point of the positioning seat is continuously increased to compress the first elastic element, thus making the change in position of the actuating element more efficient. During the transition of the locking end from point B to point C, the distance between the locking end and the pivot point of the positioning seat remains unchanged, resulting in a very smooth rotation of the positioning seat and the rotating roller.

[0010] Furthermore, the mounting shell comprises a housing, a first partition, a second partition, a first mounting seat and a second mounting seat, wherein the first partition and the second partition are each arranged on both sides of the housing, wherein the first mounting seat is fixedly connected to the first partition, wherein the second mounting seat is fixedly connected to the second partition, wherein a strip-shaped slide is arranged on the first mounting seat, wherein the actuating element comprises a motion rod and a positioning block, wherein the positioning block is fixedly connected to the motion rod, wherein the locking end is an end of the motion rod near the positioning seat, and wherein the positioning block is always slidably connected to the strip-shaped slide.

[0011] The above technical solution stabilizes the connection through the interaction of the positioning block and the strip-shaped slide, thereby standardizing the movable stroke of the movement rod and the locking end mounted on it. This avoids unnecessary work, thus increasing efficiency.

[0012] Furthermore, the actuating element is provided with a holding section, which is attached to the side of the movement rod facing away from the positioning seat. This technical solution makes it more convenient for the user to grasp and control the actuating element, thus improving the user experience.

[0013] Furthermore, it is provided that an escape opening for the passage of the movement rod is arranged at the bottom of the mounting shell, wherein the movement rod is arranged vertically, with the locking end being the upper end of the movement rod.

[0014] With the above technical solution, the user pulls the gripping section downwards, thus separating the locking end and the locking section. The parallel tent according to the present utility model is installed on the roof of the car, so the method of pulling the gripping section downwards more closely corresponds to the natural movements of the human body, making it easier to use and improving the overall experience.

[0015] Furthermore, it is provided that a first escape bore is arranged on the first partition wall, wherein a first installation hole is arranged on the first mounting seat, wherein a second escape bore is arranged on the second partition wall, wherein a second installation hole is arranged on the second mounting seat, wherein a connecting seat is fixedly arranged on the rotary roller, wherein a first bearing is arranged between the positioning seat and the first installation hole, and wherein a second bearing is arranged between the connecting seat and the second installation hole.

[0016] The above technical solution makes the rotation of the rotary roller smoother through the arrangement of the first bearing and the second bearing.

[0017] Furthermore, it is provided that the elastic means is a torsion spring, wherein one end of the torsion spring is connected to the positioning seat, and the other end of the torsion spring is connected to the second mounting seat.

[0018] Thanks to the above technical solution, the torsion spring has the advantages of excellent elasticity and durability.

[0019] Furthermore, the folding linkage is provided to have a first support rod and a second support rod which are rotatably connected to each other, wherein the first support rod is slidably connected to a locking block and a drive block, wherein the sliding directions of the locking block and the drive block intersect, wherein a detent slot is arranged on the second support rod, wherein a second elastic element is arranged in contact between the locking block and the first support rod, wherein the second elastic element is used to force the locking block to engage in the detent slot, wherein an output end is arranged on the locking block, wherein a ramp is arranged on the drive block, wherein the ramp is used to push the output end so that the locking block and the detent slot are separated from each other.

[0020] The above technical solution replaces the conventional gas spring structure with a locking block, drive block, and detent slot, thus holding the first and second support poles in an extended position. During use, this prevents collisions with the human body due to the tent unfolding too quickly, thereby increasing safety. As the user slides the drive block, the output end can be pushed through the ramp to release the locking block from the detent slot. This releases the lock between the first and second support poles, restoring the pivoting connection, thus simplifying operation.When the first support rod and the second support rod are unfolded to a certain angle, the locking block is automatically engaged in the detent slot by the second elastic element, making it more convenient to use.

[0021] Furthermore, it is provided that a column-shaped surface is arranged at the end of the second support rod, wherein the column-shaped surface is in contact with the locking slot, and wherein the locking block rests against the column-shaped surface when the locking block and the locking slot are separated from each other.

[0022] The above technical solution allows the locking block to slide on the column-shaped surface when the first support rod and the second support rod are rotated relative to each other, thus making the relative rotation of the first support rod and the second support rod smoother.

[0023] Furthermore, it is provided that a gripping section is arranged on the drive block, wherein the gripping section and the first support rod are separated from each other, with the ramp being directed obliquely to one side of the gripping section.

[0024] The above technical solution, with its arrangement of the gripping section, makes it more convenient to grasp the drive block with the human hand. The user pulls the drive block out so that the output end is driven by the ramp, which more closely corresponds to the force exerted by the human body.

[0025] Furthermore, it is provided that the first support rod has a rod element and a connecting head which are firmly connected to each other, wherein a strip-shaped recess is arranged on the connecting head, wherein the drive block is arranged in the strip-shaped recess, wherein a strip-shaped through-hole is arranged on the drive block, wherein the first screw passes through the strip-shaped through-hole and is screwed to the connecting head, wherein the strip-shaped recess and the strip-shaped through-hole extend in the same direction, wherein a slide for receiving a locking block is arranged on the connecting head, wherein an escape bore is arranged in connection between the slide and the strip-shaped recess, wherein the escape bore is used to guide the output end;further comprising a cover plate and a second screw, wherein the second screw passes through the cover plate and is screwed to the connecting head, the slide being covered by the cover plate.

[0026] The above technical solution allows the first screw to pass through the strip-shaped through-hole and be screwed into the connecting head to facilitate the installation of the drive block, thus simplifying the installation process. The drive block is confined between the inner wall of the strip-shaped recess and the end of the first screw, ensuring a very stable sliding connection. The length of the strip-shaped through-hole limits the stroke of the drive block to prevent unnecessary movement. When the locking block is positioned in the slide, the output end is also placed in the through-hole. Finally, the cover plate is securely fastened to the connecting head with a second screw to complete the installation of the locking block and prevent its separation.

[0027] The present utility model relates to the technical field of car-mounted tents, in particular to a parallel tent with safety in use, comprising a mounting bracket, a swivel caster, a folding frame, a connecting frame and a tarpaulin, wherein the swivel caster is rotatably connected to the mounting bracket, wherein the folding frame is connected between the mounting bracket and the connecting frame, wherein one end of the tarpaulin is connected to the swivel caster and the other end of the tarpaulin is connected to the connecting frame, wherein an elastic means for driving the rotation of the swivel caster is arranged on the mounting bracket, wherein an actuating element is slidably connected to the mounting bracket, wherein the actuating element has a locking end, wherein a first elastic element is connected together with the mounting bracket and the actuating element, and wherein a positioning seat is fixedly connected to the swivel caster.wherein a locking section is arranged on the positioning seat, wherein the rotating roller and the positioning seat are locked relative to the mounting shell when the locking end is forced by the first elastic element to cooperate with the locking section.

[0034] The user must move the actuating element 6 away from the positioning seat 8 so that the locking end 601 and the locking section 802 are separated. The elastic release of the elastic means drives the rotation of the rotating roller 2 to wind up the tarpaulin 5. During this process, the user must always hold the actuating element 6 and keep the locking end 601 out of contact with the locking section 802 so that the rotating roller 2 can rotate continuously to wind up the tarpaulin 5 smoothly. If it is observed that the folding rod 3 or the connecting frame 4 is about to strike the user, the user releases the actuating element 6 by hand.The first elastic element 7 automatically forces the locking end 601 and the locking section 802 to interact and connect again, stopping the rotation of the rotating roller 2, thus ensuring safe operation. Throughout the entire process of winding the tarpaulin 5, the user naturally monitors the winding status of the tarpaulin 5 and the movements of the folding rod 3 and the connecting frame 4, while always gripping the actuating element 6, further enhancing safety during the winding process.

[0035] Furthermore, it is provided that the direction of rotation of the rotary roller 2 is the winding direction when the tarpaulin 5 is wound up, and the direction of rotation of the rotary roller 2 is the unwinding direction when the tarpaulin 5 is unwound, wherein a contact flank 801 is arranged on the circumferential side of the positioning seat 8 for contact with the locking end 601, wherein an A-point 8011 and a C-point 8013 are arranged at both ends of the contact flank 801, wherein during the transition from the A-point 8011 to the C-point 8013 in the winding direction, the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 increases continuously or discontinuously, wherein the locking section 802 is a stop section arranged between the A-point 8011 and the C-point 8013, with reference to Fig. 4.

[0036] The connecting frame 4 is driven by the user to unwind the tarpaulin 5 outwards. If the user does not exert any pulling force on the actuating element 6, the locking end 601 gradually moves from point A 8011 to point C 8013 as it passes the contact flank 801, and drops directly from point C 8013 to point A 8011 as it passes the stop section. That is, the locking end 601 does not directly contact the stop section to form a lock. There is no need for the user to control the actuating element 6 while the tarpaulin 5 is unwinding, which makes it very convenient to use.

[0037] Furthermore, it is provided that during the transition from point A 8011 to point C 8013 in the winding direction, the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 increases continuously. This means that, in this way, the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 increases as the angle of this point relative to the center of rotation of the positioning seat 8 changes.

[0038] Furthermore, it is provided that during the transition from point A 8011 to point C 8013 in the winding direction, the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 does not increase continuously. This means that along this path, the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 either increases or remains unchanged if the angle of this point relative to the center of rotation of the positioning seat 8 changes. On at least one of these sections along this path, the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 increases if the angle of this point relative to the center of rotation of the positioning seat 8 changes.On at least one of these sections along this path, the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 remains unchanged when the angle of this point relative to the center of rotation of the positioning seat 8 changes. Preferably, according to the present utility model, it is provided that during the transition from point A 8011 to point C 8013 in the winding direction, the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 does not increase continuously. The specific change process is described below.

[0039] Furthermore, a B-point 8012 is arranged on the contact flank 801, wherein during the transition from the A-point 8011 to the B-point 8012 in the winding direction the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 increases continuously, wherein during the transition from the B-point 8012 to the C-point 8013 in the winding direction the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 remains unchanged.

[0040] The connecting frame 4 is driven by the user to unwind the tarpaulin 5 outwards. During the transition of the locking end 601 from point A 8011 to point B 8012, the distance of the locking end 601 from the pivot point of the positioning seat 8 is continuously increased to compress the first elastic element 7, thus making the change in position of the actuating 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 pivot point of the positioning seat 8 remains unchanged, resulting in a very smooth rotation of the positioning seat 8 and the rotating roller 2.

[0041] Furthermore, it is provided that during the transition from point A 8011 to point B 8012 in the winding direction, the distance of the point on the contact flank 801 from the center of rotation of the positioning seat 8 increases linearly, with the contact flank 801 being arc-shaped between point A 8011 and point B 8012. The smooth transition at point B 8012 makes the locking end 601 move more smoothly between point A 8011 and point B 8012, and at point B 8012 itself, thus improving ease of use.

[0042] It should be noted that the purpose of A-point 8011, B-point 8012 and C-point 8013 is to indicate the specific position of the point in the circumferential direction relative to the center of rotation of the positioning seat 8, and is not used to indicate the position of the point in the axial direction of the positioning seat 8.

[0044] The connection is stabilized by the interaction of the positioning block 603 and the strip-shaped slide 1041, thereby standardizing the movable stroke of the movement rod 602 and the locking end 601 mounted on it. This avoids unnecessary work, thus making the application more efficient.

[0045] The first elastic element 7 is a spring that is sheathed on the movement rod 602.

[0046] Furthermore, it is provided that the actuating element 6 also has a retaining section 604, wherein the retaining section 604 is attached to the side of the movement rod 602 facing away from the positioning seat 8, with reference to Fig. 3

[0047] It is more convenient for the user to grasp and control the actuating element 6 through the arrangement of the gripping section 604, thus improving the user experience.

[0048] The gripping section 604 can be designed as a handle, pull strap or pull tab, wherein the gripping section 604 in the present utility model is preferably a pull tab.

[0049] Furthermore, it is provided that an escape opening 110 for the passage of the movement rod 602 is arranged at the bottom of the mounting shell 1, wherein the movement rod 602 is arranged vertically, wherein the locking end 601 is the upper end of the movement rod 602.

[0050] The user pulls the gripping section 604 downwards, separating the locking end 601 and the locking section 802. The parallel tent according to the present utility model is installed on the roof of the car, so the way of pulling the gripping section 604 downwards is more in line with human movement, making it easier to use and improving the user experience.

[0051] Furthermore, it is provided that a first escape bore 106 is arranged on the first partition wall 102, wherein a first installation hole 108 is arranged on the first mounting seat 104, wherein a second escape bore 107 is arranged on the second partition wall 103, wherein a second installation hole 109 is arranged on the second mounting seat 105, wherein a connecting seat 9 is fixedly arranged on the rotary roller 2, wherein a first bearing 11 is arranged between the positioning seat 8 and the first installation hole 108, and wherein a second bearing 12 is arranged between the connecting seat 9 and the second installation hole 109, with reference to Fig. 5

[0052] The rotation of the rotary roller 2 is made smoother by the arrangement of the first bearing 11 and the second bearing 12.

[0053] The first bearing 11 and the second bearing 12 are preferably self-lubricating bearings, with copper bearings being selected for the first bearing 11 and the second bearing 12 in particular.

[0054] Furthermore, it is provided that the elastic means is a torsion spring 10, wherein one end of the torsion spring 10 is connected to the positioning seat 8, and the other end of the torsion spring 10 is connected to the second mounting seat 105.

[0056] Furthermore, the folding linkage 3 is provided to have a first support rod 301 and a second support rod 302, which are rotatably connected to each other, wherein the first support rod 301 is slidably connected to a locking block 303 and a drive block 304, wherein the sliding directions of the locking block 303 and the drive block 304 intersect, wherein a detent slot 3021 is arranged on the second support rod 302, wherein a second elastic element 305 is arranged in contact between the locking block 303 and the first support rod 301, wherein the second elastic element 305 is used to force the locking block 303 to engage in the detent slot 3021, wherein an output end 3031 is arranged on the locking block 303, and wherein a ramp 3041 is arranged on the drive block 304, wherein the ramp 3041 is used to push the output end 3031,so that the locking block 303 and the detent slot 3021 are separated from each other, with reference to , Fig. 6 to Fig. 9.

[0057] The conventional gas spring structure is replaced by the structure of the locking block 303, the drive block 304, and the detent slot 3021, thus holding the first support pole 301 and the second support pole 302 in an extended position. During use, this prevents collisions with the human body due to the parallel tent unfolding too quickly, thereby increasing safety. As the user slides the drive block 304, the output end 3031 can be pushed through the ramp 3041 to separate the locking block 303 from the detent slot 3021. This releases the lock between the first support pole 301 and the second support pole 302, restoring the pivot connection state, thus simplifying operation.When the first support rod 301 and the second support rod 302 are unfolded to a certain angle, the locking block 303 is automatically engaged in the detent slot 3021 by the second elastic element 305, making it more convenient to use.

[0060] The locking block 303 slides on the column-shaped surface 3022 when the first support rod 301 and the second support rod 302 are rotated relative to each other, so that the relative rotation process of the first support rod 301 and the second support rod 302 is smoother.

[0061] Furthermore, it is provided that a gripping section 3042 is arranged on the drive block 304, wherein the gripping section 3042 and the first support rod 301 are separated from each other, wherein the ramp 3041 is directed obliquely to one side of the gripping section 3042.

[0062] The arrangement of the gripping section 3042 makes it more convenient to grasp the drive block 304 with the human hand. The user pulls out the drive block 304 so that the output end 3031 is driven by the ramp 3041, which more closely corresponds to the force exerted by the human body.

[0063] The present utility model further comprises a first screw 306, wherein the first support rod 301 has a rod element 3011 and a connecting head 3012 which are fixedly connected to each other, wherein a strip-shaped recess 3013 is arranged on the connecting head 3012, wherein the drive block 304 is arranged in the strip-shaped recess 3013, wherein a strip-shaped through-hole 3043 is arranged on the drive block 304, wherein the first screw 306 passes through the strip-shaped through-hole 3043 and is screwed to the connecting head 3012, wherein the strip-shaped recess 3013 and the strip-shaped through-hole 3043 extend in the same direction, wherein a slide 3014 for receiving a locking block 303 is arranged on the connecting head 3012, and wherein an escape bore 3015 is connected is located between the slide 3014 and the strip-shaped recess 3013,wherein the alternative bore 3015 is used for guiding the output end 3031, wherein the present utility model further comprises a cover plate 307 and a second screw 308, wherein the second screw 308 passes through the cover plate 307 and is screwed to the connecting head 3012, wherein the slide 3014 is covered by the cover plate 307, with reference to , Fig. 8, Fig. 10 and Fig. 11.

[0064] The first screw 306 passes through the strip-shaped through-hole 3043 and is screwed to the connecting head 3012 to facilitate the installation of the drive block 304, thus simplifying its installation. The drive block 304 is confined between the inner wall of the strip-shaped recess 3013 and the end of the first screw 306, ensuring a very stable sliding connection. The length of the strip-shaped through-hole 3043 limits the stroke of the drive block 304 to prevent inefficient operation. When the locking block 303 is positioned in the slide 3014, the output end 3031 is also positioned in the auxiliary bore 3015. Then the cover plate 307 is firmly connected to the connecting head 3012 with a second screw 308 to complete the installation of the locking block 303 and to prevent the separate separation of the locking block 303.

[0065] In the parallel tent according to the present utility model, the connecting frame 4 is gradually driven away from the mounting bracket 1 by the user as the tarpaulin 5 is unwound. This unfolds the folding frame 3 and rotates the swivel roller 2 together with the positioning seat 8 in the unwinding direction to unwind the tarpaulin 5 outwards. Control of the actuating element 6 by the user is also not required. The locking end 601 slides on the opposite contact flank 801 in the winding direction and completes several revolutions.

[0066] 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 column-shaped area 3022 until the locking block 303 is aligned with the detent slot 3021. Under the action of the second elastic element 305, the locking block 303 is automatically engaged in the detent slot 3021, thereby achieving the angular locking of the first support rod 301 and the second support rod 302.

[0067] For the parallel tent according to the present utility model, when winding up the tarpaulin 5, the user first grasps the gripping section 3042 and pulls the drive block 304. The output end 3031 can be pushed through the ramp 3041 to drive the separation of the locking block 303 from the detent slot 3021. This releases the locking of the first support rod 301 and the second support rod 302 to restore the rotary connection state. The gripping section 604 is then always held by the user to keep the locking end 601 from being at the stop of the stop section, so that the rotating roller 2 is continuously turned and the tarpaulin 5 is wound up smoothly. If it is observed that the folding pole 3 or the connecting frame 4 is about to strike the user's body, the user releases the holding section 604.The first elastic element 7 automatically forces the locking end 601 to move upwards and engage the stop section to halt the rotation of the rotary roller 2. The above are only preferred embodiments of the present utility model and thus do not limit the scope of the patent. Any equivalent structural transformation or direct / indirect application in other related technical fields, carried out within the scope of the concept of the present utility model using the content of the description and drawings of the present utility model, falls within the scope of patent protection of the present utility model.
