Description

Technical Field

[0001] This application relates to the field of automobile trunk technology, and in particular to a luggage stop lever and limiting device. Background Technology

[0002] The trunk of a car is a specific area in a car used for storing items, usually luggage and other items carried by people when traveling.

[0003] However, during driving, the car may experience bumps due to uneven road conditions, and there may be sudden braking or acceleration. At this time, the trunk will move under the influence of inertia, and the trunk will continuously collide with the interior of the car. In severe cases, it may even tip over, which can easily damage fragile luggage, indicating a significant drawback. Utility Model Content

[0004] In order to limit the luggage in the trunk and prevent the luggage from moving while the car is in motion, this application provides a luggage stop bar and a limiting device.

[0005] In a first aspect, this application provides a luggage stop lever, which adopts the following technical solution:

[0006] A luggage stop lever for locking in the trunk of a vehicle to limit luggage, the luggage stop lever comprising,

[0007] A sliding seat, on which an mounting cylinder is provided;

[0008] The support rod is detachably connected inside the mounting cylinder;

[0009] A knob is rotatably connected to the end of the sliding seat away from the mounting cylinder;

[0010] A locking component, disposed inside the sliding seat and located on the side near the mounting cylinder, is used to fix the support rod inside the mounting cylinder;

[0011] An unlocking mechanism is disposed inside the sliding seat and located on the side near the knob. When the knob is rotated, the unlocking mechanism releases the support rod from its fixed position within the mounting cylinder.

[0012] A sliding rod is slidably connected within the sliding seat and coaxially arranged with the knob. A locking block is provided at the end of the sliding rod away from the knob. The locking block is used to lock the sliding state of the sliding seat. When the knob is rotated, the knob releases the locking state of the locking block through the unlocking mechanism.

[0013] By adopting the above technical solution, before driving, the luggage detour is installed in the trunk. The user rotates the knob, and the knob releases the locking block from the sliding seat through the unlocking component. Then, the user moves the support rod by sliding the sliding seat, so that the luggage is restricted between the support rod and the trunk, thereby limiting the luggage of different sizes and making it difficult for the luggage to move while the car is in motion.

[0014] Optionally, the locking assembly includes a locking frame slidably connected to the sliding seat. The locking frame has a locking part on the side facing the mounting cylinder. The mounting cylinder has a receiving groove that slides with the locking part. The support rod has an insertion groove that inserts with the locking part. The locking part has a guide arc surface that is inclined from top to bottom along a direction close to the axis of the mounting cylinder. The end of the locking frame away from the locking part has a guide post. A locking spring is sleeved on the outer surface of the guide post. When locking the support rod, the locking part is inserted into the insertion groove under the elastic force of the locking spring.

[0015] By adopting the above technical solution, during the process of inserting the support rod downward into the mounting cylinder, the support rod first contacts the guide arc surface. As the support rod moves downward, it pushes the locking frame towards the knob through the inclined surface of the guide arc surface. At this time, the locking spring is compressed, and the locking part is embedded in the receiving groove. When the support rod is fully inserted into the mounting cylinder, the insertion groove and the receiving groove are aligned. At this time, the pressure of the outer surface of the support rod on the locking part disappears, the locking spring resets, and pushes the locking part into the insertion groove, thereby locking the support rod. The setting of the locking component improves the stability of the support rod inside the mounting cylinder and prevents the luggage from colliding with the support rod and causing it to fall out of the mounting cylinder when bumping, thus ensuring the limiting function of the luggage stop bar.

[0016] Optionally, the unlocking mechanism includes a drive cylinder disposed on the knob near the end of the sliding rod. The drive cylinder is coaxially disposed with the sliding rod. The end face of the drive cylinder facing the sliding rod is provided with a plurality of drive grooves. The plurality of drive grooves are evenly distributed around the axis of the drive cylinder. Each drive groove has a drive surface and a guide surface. The guide surface is inclined from top to bottom in a clockwise direction, and the drive surface is vertically disposed.

[0017] A connecting cylinder is fixedly sleeved on the outer surface of the sliding rod facing the driving cylinder. The connecting cylinder is inserted into the driving cylinder. A movable block corresponding to a plurality of driving slots is provided on the end face of the connecting cylinder facing the driving cylinder. The movable block is slidably engaged with the driving slot. The outer surface of the movable block is slidably attached to the driving surface and the guiding surface. A return spring is sleeved on the outer surface of the sliding rod. One end of the return spring is provided on the surface of the sliding seat, and the other end is provided on the sliding rod. The return spring is used to drive the sliding rod to move toward the knob.

[0018] A pusher block is positioned on the side of the connecting cylinder near the locking frame, and the pusher block is inclined from top to bottom along the direction of the sliding rod toward the mounting cylinder;

[0019] An abutting wedge is disposed on the side of the locking frame near the sliding rod. The abutting wedge is inclined from top to bottom along the direction of the sliding rod toward the mounting cylinder, and the inclined surface of the abutting wedge slides against the inclined surface of the pushing wedge; and

[0020] A limiting component, wherein the limiting member is used to limit the relative movement of the knob in the vertical direction.

[0021] By adopting the above technical solution, when the luggage lever is in the working state, the return spring maintains the drive groove and the guide protrusion in close contact, the push block and the abutting block are in a relatively stationary state, and the locking part is inserted into the insertion groove.

[0022] When the knob is rotated clockwise, the knob drives the drive cylinder to rotate, and the drive cylinder drives the drive groove to rotate clockwise. At this time, the drive surface pushes the moving block to move. Due to the limitation component restricting the vertical movement of the knob and the drive cylinder, and under the guidance of the guide surface, the moving block will move downward while moving clockwise. The moving block drives the connecting cylinder and the sliding rod to move downward, and the sliding rod drives the locking block to move downward. At this time, the locking effect of the locking block on the sliding seat disappears.

[0023] As the connecting cylinder moves downward, the pushing block moves downward as well. At this time, the pushing block exerts downward pressure on the resisting block. The downward pressure is converted into a thrust towards the knob through the inclined surface. At this time, the resisting block drives the locking frame to move towards the knob. The locking frame drives the locking part to disengage from the insertion slot and embed into the receiving slot, thereby realizing the function of releasing the locking component.

[0024] Optionally, the limiting component includes a limiting ring fixedly sleeved on the outer surface of the knob, a limiting arc groove that slides and engages with the limiting ring on the sliding seat, a limiting frame on the sliding seat, a sliding rod disposed within the limiting frame, one end of the limiting ring abutting against the inner sidewall of the limiting arc groove, and the other end abutting against the surface of the limiting frame.

[0025] By adopting the above technical solution, during the rotation of the knob, the limit frame and the limiting arc groove are used to limit the knob in the vertical direction, so as to prevent the knob from moving up and down and thus hindering the transmission of each component in the unlocking mechanism, and ensuring the smooth operation of the unlocking component.

[0026] Secondly, this application provides a limiting device, which adopts the following technical solution:

[0027] Optionally, the limiting device includes two relatively parallel slide rails, each slide rail having a luggage stop bar. The sliding seat of the luggage stop bar is slidably connected to the slide rail. The slide rail has a plurality of limiting teeth evenly spaced along its length, and adjacent limiting teeth form a limiting groove. The limiting groove is used to limit the movement of the locking block of the luggage stop bar. The sliding seat has a connecting groove communicating with the limiting groove. By rotating the knob, the locking block can be inserted into or disengaged from the limiting groove and the connecting groove.

[0028] By adopting the above technical solution, when the luggage barrier blocks the luggage, the return spring drives the locking block to stay in the connecting groove. At this time, the two ends of the locking block extend out of the connecting groove and are engaged in the sliding groove formed by the two limiting teeth, thereby restricting the movement of the sliding seat.

[0029] When the sliding seat is pushed, the user turns the knob clockwise. The knob moves the sliding rod downward through the unlocking mechanism. The sliding rod pushes the locking block downward. At this time, the locking block disengages from the arc-limiting groove and the connecting groove. The user can then push the sliding seat to adjust the position of the luggage stop bar on the slide rail, thereby achieving the effect of restricting luggage of different sizes.

[0030] Optionally, multiple intercepting bars are provided between the two luggage detours. All of the multiple intercepting bars are telescopic bars. Each of the support bars is provided with a support cylinder that corresponds one-to-one with the multiple intercepting bars. The support cylinder is detachably connected to the intercepting bar.

[0031] By adopting the above technical solution, the setting of the intercepting bar increases the release area between the limiting device and the luggage, thereby improving the limiting effect on the luggage. At the same time, using a telescopic bar as the intercepting bar allows the length of the intercepting bar to be adjustable, achieving the limiting effect on luggage of different lengths.

[0032] Optionally, a shock-absorbing sleeve is provided at the connection between each of the support cylinders and the interceptor rod, and the shock-absorbing sleeve is made of an elastic material.

[0033] By adopting the above technical solution, when the vehicle is bumpy, the trunk will continuously collide with the interceptor and cause the interceptor to shake. At this time, the shock absorber will effectively absorb the vibration energy generated by the shaking of the interceptor by utilizing its elastic properties, thereby effectively reducing the direct rigid collision at the connection between the interceptor and the support rod, effectively reducing the generation of abnormal noise, and at the same time improving the service life of the limiting device.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. This application sets up an unlocking mechanism and a knob. Rotating the knob changes the position of the locking block, thus restricting the luggage between the support rod and the trunk, thereby limiting the luggage of different sizes and making it less likely to move while the car is in motion.

[0036] 2. This application incorporates a locking component, which enhances the stability of the support rod within the mounting cylinder, preventing luggage from colliding with the support rod and dislodging it from the mounting cylinder during bumpy conditions, thus ensuring the limiting function of the luggage stop bar.

[0046] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0047] Example 1

[0048] This application discloses a luggage stop bar.

[0049] Reference Figure 1 A luggage rack includes a sliding seat 1, with a T-shaped sliding block (not shown in the figure) fixedly connected to the bottom of the sliding seat 1. An mounting cylinder 2 is integrally formed on the surface of the sliding seat 1, and a support rod 3 is detachably connected inside the mounting cylinder 2. The support rod 3 is installed vertically in the trunk of the car, and a knob 4 is rotatably connected to the side of the sliding seat 1 away from the mounting cylinder 2.

[0050] Reference Figures 2 to 5 The sliding seat 1 is provided with a locking component 5. The locking component 5 is located on the side of the sliding seat 1 near the mounting cylinder 2. The locking component 5 includes a locking frame 51 that is slidably connected to the sliding seat 1. The sliding direction of the locking frame 51 is perpendicular to the length direction of the mounting cylinder 2. The locking frame 51 is provided with a locking part 52 on the side facing the mounting cylinder 2. The locking part 52 is integrally formed with the locking frame 51. The outer wall of the mounting cylinder 2 is provided with a receiving groove 21 that slides with the locking part 52. The outer surface of the support rod 3 is provided with an insertion groove 31 that inserts with the locking part 52. The locking part 52 has a guide arc surface 521. The guide arc surface 521 is inclined from top to bottom along the direction close to the axis of the mounting cylinder 2.

[0051] Reference Figures 2 to 5Two guide posts 53 are fixedly connected to the end of the locking frame 51 away from the locking part 52. The two guide posts 53 are respectively set on opposite sides of the locking frame 51. A locking spring 54 is sleeved on the outer surface of each guide post 53. One end of the locking spring 54 is fixedly connected to the outer surface of the sliding seat 1, and the other end is fixedly connected to the outer surface of the guide post 53. After the support rod 3 is inserted into the mounting cylinder 2, the locking part 52 is inserted into the insertion groove 31 under the elastic force of the locking spring 54.

[0052] When installing the support rod 3, the user inserts the support rod 3 downward into the mounting cylinder 2. As the bottom surface of the support rod 3 moves downward, it first contacts the guide arc surface 521. The inclined surface of the guide arc surface 521 pushes the locking frame 51 and the guide post 53 to move towards the knob 4. At this time, the locking spring 54 is compressed, and the locking part 52 is embedded in the receiving groove 21. When the support rod 3 is fully inserted into the mounting cylinder 2, the insertion groove 31 is aligned with the receiving groove 21, the pressure of the support rod 3 on the locking part 52 disappears, the locking spring 54 resets and pushes the locking part 52 into the insertion groove 31, thereby locking the support rod 3. The setting of the locking component 5 improves the stability of the support rod 3 inside the mounting cylinder 2, and prevents the luggage from colliding with the support rod 3 and causing it to fall out of the mounting cylinder 2 when bumpy, thus ensuring the limiting function of the luggage stop bar.

[0053] Reference Figures 2 to 5 A sliding rod 6 is slidably connected to the end of the sliding seat 1 away from the mounting cylinder 2. The bottom end of the sliding rod 6 extends out of the sliding seat 1. The sliding rod 6 is coaxially arranged with the knob 4. A locking block 61 is fixedly connected to the end of the sliding rod 6 away from the knob 4. The locking block 61 is used to lock the sliding state of the sliding seat 1. The locking block 61 is located below the sliding seat 1. A connecting groove 102 is provided on the sliding seat 1 to slide with the locking block 61. When the locking block 61 is inside the connecting groove 102, both ends of the locking block 61 extend out of the connecting groove 102, and the sliding of the locking block 61 is restricted. When the locking block 61 is disengaged from the connecting groove 102, the locking block 61 can slide.

[0054] Reference Figures 2 to 5 The sliding seat 1 is provided with an unlocking mechanism 7 on the side near the sliding rod 6. When the knob 4 is rotated, the knob 4 releases the fixed state of the support rod 3 inside the mounting cylinder 2 through the unlocking mechanism. At this time, the user can take out the support rod 3. The knob 4 switches the position of the locking block 61 through the unlocking mechanism 7. The user can slide the sliding seat 1 to change the position of the luggage bar.

[0055] Reference Figures 2 to 6The unlocking mechanism 7 includes a drive cylinder 71, a connecting cylinder 72, a pushing wedge 73, an abutting wedge 74, a return spring 75, and a limiting assembly 76. The drive cylinder 71 is fixedly connected to the end of the knob 4 near the sliding rod 6. The drive cylinder 71 is coaxially arranged with the sliding rod 6 and the knob 4. Multiple drive grooves 711 are provided on the outer end face of the drive cylinder 71 facing the sliding rod 6. Two drive grooves 711 are evenly distributed around the axis of the drive cylinder 71. In this embodiment, there are two drive grooves 711.

[0056] Reference Figures 2 to 6 The drive groove 711 has a drive surface 7111 and a guide surface 7112, wherein the drive surface 7111 is a vertical plane and the guide surface 7112 is an inclined surface, and the guide surface 7112 is inclined from top to bottom in a clockwise direction.

[0057] Reference Figures 2 to 6 A connecting cylinder 72 is fixedly sleeved on one end of the sliding rod 6 facing the drive cylinder 71. The connecting cylinder 72 is coaxially arranged with the drive cylinder 71 and is inserted into it. A movable block 721 corresponding to the two drive grooves 711 is integrally formed on the end face of the connecting cylinder 72 facing the drive cylinder 71. The movable block 721 is slidably engaged with the drive groove 711, and the outer surface of the movable block 721 is slidably attached to the drive surface 7111 and the guide surface 7112. The movable block 721 is a triangular block to adapt to the shape of the drive groove 711.

[0058] Reference Figures 2 to 6 A return spring 75 is sleeved on the outer surface of the sliding rod 6. One end of the return spring 75 is fixedly connected to the surface of the sliding seat 1, and the other end is fixedly connected to the sliding rod 6. When the knob 4 is rotated, the return spring 75 is in a compressed state. The return spring 75 is used to drive the sliding rod 6 to move toward the knob 4.

[0059] Reference Figure 5 and Figure 6 A pushing inclined block 73 is fixedly connected to the outer surface of the connecting cylinder 72 near the locking frame 51. The pushing inclined block 73 is inclined from top to bottom along the sliding rod 6 toward the mounting cylinder 2. An abutting inclined block 74 is fixedly connected to the side of the locking frame 51 near the sliding rod 6. The abutting inclined block 74 is inclined from top to bottom along the sliding rod 6 toward the mounting cylinder 2. The inclined surface of the abutting inclined block 74 slides against the inclined surface of the pushing inclined block 73.

[0060] Reference Figure 2 and Figure 3The limiting component 76 includes a limiting ring 761 fixedly sleeved on the outer surface of the knob 4. A limiting arc groove 101 is provided at one end of the sliding seat 1 near the knob 4. The limiting ring 761 is slidably connected inside the limiting arc groove 101. A limiting frame 762 is fixedly connected on the sliding seat 1. The limiting frame 762 includes two opposing limiting plates, which are respectively provided on both sides of the sliding rod 6. The bottom surface of the limiting ring 761 abuts against the surface of the limiting frame 762, and the other end abuts against the inner side wall of the limiting slide groove 81. Under the limiting of the limiting component 76, the knob 4 cannot move in the vertical direction.

[0061] The implementation principle of Example 1 is as follows: Before driving, the luggage compartment lever is installed in the trunk. The user rotates the knob 4 clockwise, which drives the drive cylinder 71 to rotate. The drive cylinder 71 drives the drive groove 711 to rotate clockwise. At this time, the drive surface 7111 pushes the moving block 721 to move. Due to the limitation component 76 restricting the vertical movement of the knob 4 and the drive cylinder 71, and under the guidance of the guide surface 7112, the moving block 721 moves downward while moving clockwise. The moving block 721 drives the connecting cylinder 72 and the sliding rod 6 to move downward. The sliding rod 6 drives the locking block 61 to move downward. At this time, the locking effect of the locking block 61 on the sliding seat 1 disappears, and the user can slide the sliding block 61 to move downward. The moving seat 1 drives the support rod 3 to move, thus restricting the luggage between the support rod 3 and the trunk, thereby limiting the luggage of different sizes and making it difficult for the luggage to move while the car is in motion; at the same time, as the knob 4 rotates clockwise, the connecting cylinder 72 moves downward, causing the pushing block 73 to move downward. At this time, the pushing block 73 generates downward pressure on the contact block 74, and the downward pressure is converted into a thrust towards the knob 4 through the inclined surface. The contact block 74 drives the locking frame 51 to move towards the knob 4. The locking frame 51 drives the locking part 52 to disengage from the insertion slot 31 and embed into the receiving slot 21, thereby realizing the function of releasing the locking component 5.

[0062] Example 2

[0063] Embodiment 2 of this application discloses a limiting device. The limiting device in this embodiment includes the luggage stop bar in Embodiment 1.

[0064] Reference Figure 7 and Figure 8 The limiting device also includes two relatively parallel slide rails 8, which are fixedly installed in the trunk of the car. The slide rails 8 have a groove 81 along their length, which extends to one side of the slide rail 8, making one side of the slide rail 8 open. Each slide rail 8 has a support rod slidably connected inside. The user slides the sliding block at the bottom of the sliding seat 1 into the slide rail 8 from the open end to install the support rod on the slide rail 8.

[0065] Reference Figure 7 and Figure 8Multiple limiting teeth are fixed at the opening of the slide rail 8. The multiple limiting teeth are evenly distributed along the length of the slide rail 8. A limiting groove 10 is formed between two adjacent limiting teeth. The limiting groove 10 is used to restrict the movement of the locking block 61 of the luggage stop bar. In the natural state of the return spring 75, the locking block 61 is located in the connecting groove 102. The two ends of the locking block 61 extend out of the connecting groove 102 and are inserted into the limiting groove 10. The sliding of the locking block 61 is restricted. When the knob 4 is rotated, the locking block 61 can be inserted into or disengaged from the limiting groove 10 and the connecting groove 102.

[0066] Reference Figure 7 and Figure 8 In order to improve the limiting effect of the limiting device, multiple intercepting bars 11 are provided between the two luggage bars. The intercepting bars 11 abut against the outer surface of the luggage. In this embodiment, there are two intercepting bars 11, and each intercepting bar 11 is a telescopic bar. Users can change the length of the intercepting bars 11 to adapt to luggage of different lengths.

[0067] Reference Figure 7 and Figure 8 Each support rod 3 is fixedly connected to a support cylinder 32 corresponding to one of the multiple interceptor rods 11. The support cylinder 32 is detachably connected to the interceptor rod 11. In this embodiment, the two opposite ends of the interceptor rod 11 are sleeved on the outer surface of the support cylinder 32 and fixed by bolts. Each support cylinder 32 is equipped with a shock-absorbing sleeve (not shown in the figure) at the connection between it and the interceptor rod 11. The shock-absorbing sleeve is made of elastic material. When the vehicle bumps, the trunk continuously collides with the interceptor frame and causes the interceptor frame to shake. The shock-absorbing sleeve effectively absorbs the vibration energy generated by the shaking of the interceptor frame by utilizing its elastic properties, thereby effectively reducing the direct rigid collision at the connection between the interceptor frame and the support rod 3 and effectively reducing the generation of abnormal noise.

[0068] The implementation principle of Example 2 is as follows: When the luggage bar blocks the luggage, the return spring 75 drives the locking block 61 to stay in the connecting groove 102. At this time, the two ends of the locking block 61 extend out of the connecting groove 102 and are engaged in the sliding groove 10 formed by the two limiting teeth 9, thereby restricting the movement of the sliding seat 1.

[0069] When the user pushes the sliding seat 1, the user turns the knob 4 clockwise. The knob 4 drives the sliding rod 6 to move downward through the unlocking mechanism 7. The sliding rod 6 pushes the locking block 61 to move downward. At this time, the locking block 61 disengages from the arc limiting groove and the connecting groove 102. The user can push the sliding seat 1 to adjust the position of the luggage stop bar on the slide rail 8, thereby achieving the effect of restricting luggage of different sizes.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
