Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a pickup truck guardrail. Background Art

[0002] Currently, the trunks of existing pickup trucks are factory-installed with a fixed volume because they lack expansion features. This limits their cargo capacity, so cargo that exceeds the trunk capacity often needs to be transported in batches. To reduce the number of shipments while remaining within the vehicle's load capacity, some freight operators often open and lay the trunk doors flat (some existing pickup trucks support this feature), thereby extending the depth of the truck's trunk and increasing its volume.

[0003] However, in this case, the goods are in the trunk, and due to the lack of the trunk door to block them, safety issues such as goods falling may easily occur during transportation. Although this situation can be temporarily solved by adding ropes to fix them, this will increase the workload of the transportation personnel when loading and unloading the goods.

[0004] To this end, the prior art has proposed "A Pickup Truck Trunk Extended Guardrail" (Patent Publication No.: CN112722089A), which mainly adds a guardrail assembly to the pickup truck trunk and stores it inside the pickup truck trunk under normal circumstances. When in use, the guardrail is flipped out by rotating the assembly to combine with the trunk door to expand the pickup truck trunk cargo volume.

[0005] However, such solutions also have some problems. For example, existing pickup truck trunk guardrail locking devices are often complicated to operate, lack stability, and have poor durability. Existing solutions mostly use fixed connections, which lack the flexibility to meet the needs of multi-angle adjustment and quick installation. More importantly, the rotation angle of the rotating components of the existing guardrail cannot be adjusted and fixed. Therefore, the guardrail can only block the cargo at the bottom of the trunk. In practice, when expanding the cargo capacity, the cargo is often piled up or carried higher. In this case, the guardrail may not be able to provide effective protection, which increases the risk of the cargo falling out of the guardrail during transportation, posing a safety hazard to freight operations.

[0006] The prior art also proposes another protection method, such as adding a luggage net bag to provide additional protection, but this protection method is inconvenient to operate and has a limited scope of protection for the cargo. Utility Model Content

DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0036] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or are the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance. The terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0037] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0038] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "setting", "layout", "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with the existing technology according to the specific circumstances. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other unless there is a conflict. And one or more of the components in the diagram may be necessary or non-essential, and the relative positional relationship between the components in the above diagram can be adjusted according to actual needs.

[0039] In order to realize the function of supporting the guardrail rotation angle to be adjustable and locked, such as Figures 1 to 6 As shown, the present invention proposes a rotation locking device, which includes: a base 1, a button cover 2, an elastic latch assembly 3, and a connecting plate 4, wherein, as shown in FIG. Figure 1 、 Figure 5 As shown, the base 1 is provided with a shaft seat 11, a knob seat 12, and a pin slot 13. The pin slot 13 and the knob seat 12 are respectively arranged on both sides of the base 1 and are connected through the pin hole. The connecting plate 4 is axially connected to the base 1 through the shaft seat 11 to allow the base 1 to rotate relative to the connecting plate 4 with the axis of the shaft seat 11 as the origin. A locking hole 41 is arranged on the connecting plate 4, wherein the locking hole 41 is preferably distributed on the connecting plate 4 in an arc-shaped trajectory with the axis connection of the connecting plate 4 as the center.

[0040] Among them, such as Figures 3 to 5 As shown, the knob seat 12 and the knob cover 2 are respectively provided with a guiding wall 121 and a guided wall 21 which are spirally symmetrical with each other. Figure 6 As shown, the elastic latch assembly 3 is arranged in the pin groove 13 , and the button cover 2 is covered on the knob seat 12 and connected to the linkage end of the elastic latch assembly 3 .

[0041] Among them, such as Figures 5 and 6 As shown, the elastic latch assembly 3 in this example includes: a latch 31, an elastic member 32, and a pin sleeve 33, wherein the pin sleeve 33 is sleeved in the pin groove 13 of the base 1, and a retaining ring 311 is provided at the front end of the latch 31. The elastic member 32 is a coil spring, which is sleeved on the latch 31, and the front and rear ends of the coil spring are respectively against the retaining ring 311 and the bottom wall of the pin groove 13, and the tail end of the latch 31 is connected to the button cover 2 through the pin hole.

[0042] When the cam 31 is in the closed position, the spring 33 is released and the locking cam 33 is released to the locking cam 33. When the cam 31 is in the closed position, the locking cam 33 is released and the locking cam 33 is released to the locking cam 33. When the cam 31 is in the closed position, the spring 33 is released and the locking cam 33 is released to the locking cam 33.

[0043] In order to improve the adjustable accuracy of the rotation angle, in an optional embodiment, as Figure 2 As shown, the locking holes 41 can be arranged to be connected in an eight-shaped hole shape, thereby shortening the center distance of each locking hole 41, thereby improving the adjustable accuracy of the rotation angle of the base 1 relative to the connecting plate 4.

[0044] Furthermore, in order to stabilize the spiral lifting structure between the button cover 2 and the knob seat 12 and avoid excessive twisting, as shown in FIG. Figures 3 and 4 As shown, in an optional embodiment, a stepped limiting portion 122 and a blocking portion 22 may be provided at the ends of the travel of the guiding wall 121 and the guided wall 21, respectively, and when the button cover 2 is in the initial position, the tail of the blocking portion 22 abuts against the head of the limiting portion 122.

[0045] With this arrangement, when the button cover 2 is in the initial position, if it attempts to rotate in the reverse direction by mistake, it will be restricted by the back-to-back contact between the blocking portion 22 and the limiting portion 122. When the button cover 2 rotates in the forward direction to the limit of the torsional stroke, it will be restricted by the front contact between the blocking portion 22 and the limiting portion 122, thereby forming over-limit protection in both the forward and reverse directions, thereby improving the structural reliability and stability.

[0046] In addition, considering that the button cover 2 may be vibrated under bumpy conditions, the elastic latch assembly 3 may be moved due to the friction between the latch 31 and the locking hole 41. Under these combined factors, although the probability is very small, it may cause the latch 31 to accidentally fall out of the locking hole 41. Therefore, in order to prevent such unexpected problems, in an optional embodiment, as shown in FIG. Figure 3 As shown, a gentle transition section 123 may be provided in front of the limiting portion 122 of the guiding wall 121, and a transition platform 23 is provided at the front end of the travel of the guided wall 21. The transition platform 23 is sloped on the side corresponding to the limiting portion 122, and its slope is greater than that of the remaining travel sections of the guided wall 21, and the bottom of the transition platform 23 is smooth like the transition section 123.

[0047] With this arrangement, when the button cover 2 is rotated by factors such as bumps and vibrations, the transition platform 23 will become a buffer threshold, forcing the button cover 2 to cross the transition platform 23 before the guided wall 21 is induced by the guide wall 121 to form a spiral rise, thereby preventing the button cover 2 from rotating unintentionally. At the same time, it can also prevent the button cover 2 from directly colliding with the knob seat 12 to produce abnormal noise, reduce component wear, and increase service life.

[0048] Furthermore, in order to facilitate the user to rotate the knob cover 2 and indicate the rotation range of the knob cover 2, as shown in FIG. Figure 3 、 Figure 5 As shown, in an optional embodiment, an indicator handle 5 may be provided at the blocking portion 22 of the guide wall 21 on one side of the button cover 2. Through the indicator handle 5, it is convenient for the user to hold the rotating button cover 2 with a hand.

[0049] On the other hand, corresponding to the above-mentioned rotation locking device, another aspect of the present invention further provides a pickup guardrail, such as Figures 7 to 13 As shown, the example includes: a guardrail assembly 6, a rotating assembly 7, wherein the components of the guardrail assembly 6 and the rotating assembly 7 can be made of corrosion-resistant materials, such as high-strength engineering plastics, wherein the rotating assembly 7 adopts any of the above-mentioned rotation locking devices, wherein the guardrail assembly 6 includes: a tail guardrail 61, a side guardrail 62, and an adjustment member 63, wherein the tail guardrail 61 is provided with a distance adjustment slide rail 64 on both sides, wherein as Figure 11As shown, in this example, the adjustable distance rail 64 includes: a track member 641 and a slider 642, wherein the track member 641 is fixed to both sides of the rear guardrail 61, and the slider 642 is matched with the track member 641 and slides along the track member 641. The slider 642 is provided with a screw hole. The side guardrail 62 is bent, and one end thereof is connected to the slider 642 via a bolt so as to move along the track member 641 with the slider 642. When it moves into position, the bolt is screwed through the screw hole to abut the track member 641 to fix its adjusted position. One end of the side guardrail 62 is connected to the slider 642 of the adjustable distance rail 64, and the other end is connected to the adjustment member 63. The base 1 of the rotary locking device is fixed to the rear end of the adjustment member 63.

[0050] Specifically, if Figures 11 to 13 As shown, in order to strengthen the firmness of the distance-adjusting connection structure between the rear guardrail 61 and the side guardrail 62, a first guide groove 621 may be optionally provided on the front side of the side guardrail 62 for at least partially embedding the distance-adjusting slide rail 64, thereby facilitating stable guidance of the side guardrail 62 to adjust the connection distance with the rear guardrail 61.

[0051] In addition, in order to facilitate the adjustment direction between the side guardrail 62 and the adjustment member 63, as shown in FIG. Figure 13 As shown, in an optional example, a second guide groove 622 is provided on the rear side of the side guardrail 62, and a limiting wall 631 is provided on the adjusting member 63. The adjusting member 63 is guided and matched with the second guide groove 622 through the limiting wall 631 to guide the adjustment direction of the two. When moved into place, the position is fixed by bolts.

[0052] Furthermore, in order to strengthen the rear guardrail 61, as Figures 7 to 10 As shown, in an optional embodiment, the guardrail assembly 6 further includes: buffer members 65, which are arranged on the upper and lower sides of the tail guardrail 61. When the pickup truck guardrail is installed in the pickup truck trunk, whether it is flipped up and stored in the trunk or flipped outward to abut the trunk door, the buffer members 65 can strengthen the bottom structure of the tail guardrail 61.

[0053] Through the pickup guardrail of the above example, when it is equipped with a pickup truck, it can be installed by connecting the connecting plate 4 of the rotary locking device to the two side plates of the pickup trunk. Under normal circumstances, the pickup guardrail is folded in the pickup trunk. When the trunk volume needs to be expanded, the trunk door is laid flat, the button cover 2 is twisted to pull the elastic latch assembly 3, so that the latch 31 is separated from the locking hole 41 on the connecting plate 4. At this time, after rotating the guardrail assembly 6 to a suitable angle, align it with the locking hole 41 at this position and release the torque. The elastic latch assembly 3 automatically sends the latch 31 into the locking hole 41 to complete the locking, thereby locking the rotation adjustment angle of the pickup guardrail.

[0054] In addition, other structures capable of locking and releasing the guardrail rotation point may also be adopted to achieve the rotation and locking of the guardrail.

[0055] The rotary locking device provided above is particularly suitable for pickup trucks and other scenarios where guardrails are required. By adjusting the guardrail angle, users can quickly adapt to different cargo types and improve transportation stability.

[0056] Key technical advantages include:

[0057] - Enhanced stability through elastic locking.

[0058] -Support multi-angle adjustment to meet diverse needs.

[0059] -Quick switching, no additional tools required.

[0060] -High-strength structural design with corrosion-resistant materials ensures long-term durability.

[0061] In summary, the rotary locking device provided by the present invention and the pickup guardrail made thereof cleverly designs a knob spiral lifting elastic latch 31 mechanism to support the pickup guardrail equipped with the base 1. After the base 1 rotates to the desired angle, the flip angle is locked through the locking hole 41 on the connecting plate 4 connected to the pickup trunk. This solves the defect that the flip angle cannot be adjusted and fixed when the pickup trunk is expanded. As a result, this solution can effectively protect stacked or higher cargo from the rear of the pickup trunk, thereby effectively improving the safety of cargo transportation and bringing convenience to freight work. In addition, because this solution has a size adjustment structure design on the rear guardrail 61, the side guardrail 62, and the adjustment member 63, the guardrail assembly 6 can cope with pickup trunks of various specifications and sizes, thereby improving the adaptability of the product.
