Specifically, as shown in fig. 8 and 9, the first installation portion includes the first slot 2 disposed on the D-pillar decorative plate 5, when the covering curtain 1 is in the recycling state, the side tube plug 121 of the side tube 12 is connected to the first slot 2 in a clamped manner, so as to prevent the side tube plug 121 from coming off from the first slot 2, and a certain gap should be reserved between the side tube plug 121 and the top wall of the first slot 2, preferably 0.2-0.5mm, so that the phenomenon that the soft rubber coated by the side tube plug is embedded into the first slot due to high-speed impact when the covering curtain is recycled can be avoided, which results in operation retardation. At this time, the side plug 121 is in the first working position, and the first engaging groove 2 restricts the freedom of the side plug 121 in the lateral and vertical movements, as shown in fig. 11.

Meanwhile, as shown in fig. 8 and 10, the second mounting portion includes a second clamping groove 3 formed in the D-pillar decorative plate 5, and when the object covering curtain 1 is in the unfolded state, the side pipe plug 121 is clamped in the second clamping groove 3, and the top wall and the bottom wall of the second clamping groove 3 clamp the side pipe plug 121, so that the side pipe plug 121 is prevented from being taken off from the second clamping groove 3. At this time, the side plug 121 is in the second working position, and the second engaging groove 3 restricts the freedom of the side plug 121 in the lateral and vertical movements, as shown in fig. 12.

Therefore, as shown in fig. 8, the first mounting portion and the second mounting portion in the present embodiment are implemented by forming a groove on the D-pillar trim 5, but of course, other fixing structures may be provided on the D-pillar trim 5 as long as the detachable connection with the side plug 121 is achieved. For example, the skirt plug 121 may be provided in a spring-controlled telescopic structure similar to the outer cap 111.

Further, as shown in fig. 8, the D-pillar decorative plate 5 is further provided with a guide groove 4 communicating the first clamping groove 2 and the second clamping groove 3, and the side pipe plug 121 can slide in the guide groove 4, so as to switch between the first working position and the second working position, and further switch the object covering curtain 1 between the retracted state and the extended state.

In the embodiment shown in fig. 8, the first engaging groove 2, the guiding groove 4 and the second engaging groove 3 form a groove formed in the D-pillar trim 5, two engaging grooves at two ends of the guiding groove 4 respectively correspond to two fixing points of the side plug 121, and the guiding groove 4 is a guiding groove when the side plug 121 moves between the two fixing points.

Therefore, when the object covering curtain 1 is switched between the retracted state and the extended state, the side pipe plugs 121 can slide along the guide grooves 4 to realize the switching of the working positions, and in the process, the side pipe plugs 121 are always positioned in the grooves of the D-pillar decorative plate 5. Therefore, compared with the prior art in which the side pipe plug 121 is required to be removed from the outer pipe region all the time when the working position is switched, the side pipe plug 121 is not required to be removed from the groove of the D-pillar trim 5 by providing the guide groove 4 in the embodiment, so that the reliability of the fixing structure and the convenience of operation are improved. Additionally, the utility model provides a fixed knot constructs still has simple structure, convenient operation's advantage.

In addition, in order to ensure that the side pipe plug 121 slides in the guide groove 4 without stagnation, a predetermined gap is formed between the side pipe plug 121 and the guide groove 4 along the vertical direction, and the gap can be 1-2 mm. Of course, the vertical gap between the side pipe plug 121 and the guide groove 4 is not limited to this, and may be set according to the actual working condition.

Specifically, as shown in fig. 9, the first card slot 2 has a first top wall 21 and a first bottom wall 22 which are vertically distributed, and the first top wall 21 and the first bottom wall 22 may be further connected by a first side wall facing the sliding direction of the side plug 121, so as to limit the side plug 121 from coming out of the first card slot 2 from the side away from the second card slot 3; or, in the first card slot 2, as shown in fig. 9, the first top wall 21 is inclined toward the first bottom wall 22, and the two are connected to form the first card slot 2 with a tapered cross section, at this time, the connection between the inclined first top wall 21 and the first bottom wall 22 can limit the side plug 121 from being pulled out of the first card slot 2 from the side far away from the second card slot 3.

As shown in fig. 9, the first engaging groove 2 is provided with an inclined first top wall 21, so that one side of the first engaging groove is open, the other side of the first engaging groove is closed, and the open side of the first engaging groove is communicated with the guide groove 4, that is, the first engaging groove 2 is used for limiting the freedom of movement of the side plug 121 in the direction of the recess, and does not limit the freedom of longitudinal movement of the side plug 121 in the guide groove 4.

More specifically, in order to ensure that the side plug 121 can be smoothly pulled out from the first engaging groove 2, a predetermined gap, which may be 0.2 to 0.5mm, is provided between the upper surface of the side plug 121 and the first top wall 21. Of course, other sizes of clearances may be selected in practice.

Meanwhile, as shown in fig. 10, the second card slot 3 has a second top wall 31 and a second bottom wall 32 which are vertically distributed, and the second top wall 31 and the second bottom wall 32 can be connected through a second side wall which is located at one side of the second card slot 3 close to the first card slot 2, so as to limit the side plug 121 from being pulled out of the second card slot 3 from the side close to the first card slot 2; or, in the second card slot 3, as shown in fig. 10, the second bottom wall 32 is inclined in the direction away from the second top wall 31, and the two are connected to form the second card slot 3 with a tapered cross section, at this time, the inclined second bottom wall 32 is connected to the second top wall 31, so that the side plug 121 can be limited to be pulled out of the second card slot 3 from the side close to the first card slot 2.

As shown in fig. 10, the second locking groove 3 has an inclined second bottom wall 32, so that one side thereof is open, the other side is closed, and the open side is communicated with the guide groove 4, that is, the second locking groove 3 limits the side tube plug 121 at the second working position, and can prevent the object covering curtain 1 from being automatically switched to the recovery state when being in the unfolding state.

Due to the limitation of the shape, the object covering curtain 1 and the D-pillar garnish 5 are matched at a predetermined angle, i.e., they are inclined, so that during the process of taking the side pipe plug 121 out of the fixed structure of the D-pillar garnish 5, the side pipe plug 121 also needs to be kept at the predetermined angle with the D-pillar garnish 5, i.e., the side pipe plug 121 needs to be taken out obliquely, and users are generally more accustomed to taking out the side pipe plug 121 horizontally, thus resulting in low user satisfaction of the object covering curtain.

In order to solve the technical problem, as shown in fig. 10, the second top wall 31 is inclined toward a direction away from the second bottom wall 32, and an end portion of the second top wall 31 is connected to the second bottom wall 32, so that both the second top wall 31 and the second bottom wall 32 in this embodiment are inclined planes, and the inclination directions of the two are opposite, so that the cross section of the second slot 3 near the opening thereof is larger than the vertical dimension of the side plug 121, and the side plug 121 can freely rotate at a position of the second slot 3 near the opening, that is, can rotate until the object covering curtain 1 can be horizontally taken out from the D-pillar trim 5, thereby matching with the habit of a user, so as to improve the user satisfaction of the object covering curtain 1.

Further, the second top wall 31 includes a first portion and a second portion, wherein the first portion is close to the opening of the second card slot 3, the second portion is far away from the opening of the second card slot 3, the second portion is a plane which is fixedly connected with the second bottom wall 32 and is horizontally arranged, the first portion is a curved surface which is inclined in a direction far away from the second bottom wall 32, and meanwhile, the first portion and the second portion are in smooth transition.

In this embodiment, the first portion that sets up horizontally can guarantee the reliability of being connected between limit stopcock 121 and the second draw-in groove 3, and the second portion that sets up in the slope can guarantee that limit stopcock 121 freely rotates at the opening part of second draw-in groove 3 to improve this user satisfaction who hides thing curtain 1.

On this basis, as shown in fig. 10, the second card slot 3 is communicated with the guide slot 4 through the transition slot 42, and the guide slot 4 and the second card slot 3 are located at different vertical heights, so that the transition slot 42 is used for communicating the second card slot 3 and the guide slot 4 which are vertically distributed, so that the side plug 121 enters the guide slot 4 through the transition slot 42 after being released from the second card slot 3.

With this arrangement, the second top wall 31 blocks the path of the side pipe plug 121 switched from the second operating state to the first operating state, and therefore, the side pipe plug 121 needs to pass through the transition groove 42 when switching the operating position. As shown in fig. 10, when the side pipe plug 121 is switched from the second working position to the first working position, the side pipe plug 121 needs to be manually slid along the transition groove 42 and the guide groove 4 to realize switching, and the side pipe plug 121 cannot be switched by itself, that is, when the object covering curtain 1 is in the unfolding state, the side pipe plug cannot be automatically switched to the recovery state, so as to better play a role of covering objects.

Specifically, as shown in fig. 10, the transition groove 42 is an arc-shaped groove, and when the transition groove 42 connects the guide groove 4 and the second catching groove 3, there is an inflection point 421, that is, at the inflection point 421, the moving direction of the side plug 121 is changed.

As shown in fig. 10, the height of the inflection point 421 of the transition groove 42 in the vertical direction is higher than the vertical height of the entrance of the second card slot 3.

It can be understood that the inflection point 421 of the transition groove 42 is an arc-shaped vertex, and the moving directions of the side plug 121 are opposite on both sides of the inflection point 421, and in practical operation, when the inflection point 421 is at the same level as the inlet of the second card slot 3 or lower than the inlet of the second card slot 3, there is a risk that the side plug 121 moves in the transition groove 42 due to inertia, and hits against the inlet of the second card slot 3. Therefore, in order to avoid this risk, the inflection point 421 of the transition groove 42 is set higher than the entrance of the second catching groove 3, thereby ensuring that the skirt plug 121 can smoothly slide in the transition groove 42.

In the above embodiments, when the side pipe plugs 121 slide in the first clamping groove 2, the guide groove 4, the transition groove 42, and the second clamping groove 3, the side pipe plugs 121 need to be prevented from falling out of the grooves, and therefore, the size of the side pipe plugs 121 in the grooves needs to be ensured, preferably 10-20mm, or the size may be set according to actual working conditions.

Further, as shown in fig. 9, the side wall of the guide groove 4 communicating with the first card slot 2 has an opening 41, and in the embodiment shown in fig. 9, the opening 41 is located on the upper side wall of the guide groove 4. The side pipe plugs 121 can be removed from the openings 41 by an external force to remove the side pipes 12 from the grooves of the D-pillar garnish 5. Of course, the side plug 121 may be engaged with the recess of the D-pillar garnish 5 through the opening 41. The opening size should set an upper limit, preferably 2-3 times the maximum width of the side plug.

In the above embodiments, as shown in fig. 9 and 10, the cross section of each of the first locking groove 2 and the second locking groove 3 is gradually increased along the direction in which the side plug 121 is pulled out, so as to facilitate the switching of the working position of the side plug 121.

In addition, as shown in fig. 9, the D-pillar trim 5 is further provided with a sunken table 51, the outer covers 111 of the outer tube 11 are of a spring-controlled telescopic structure, and the end portions of the two outer covers 111 are provided with bosses engaged with the sunken tables 51, so that the bosses are engaged with the sunken tables 51 of the D-pillar trim 5 on both sides under the action of spring force to realize connection between the outer tube 11 and the D-pillar trim 5.

Referring to fig. 13-14, fig. 13 is a schematic diagram of the structure of the side plug of fig. 12, and fig. 14 is an exploded schematic diagram of the structure of the side plug.

In the above embodiments, as shown in fig. 13, the side plug 121 is formed by two-shot molding, and includes a cast aluminum frame 1212, on which a buffer layer 1211 is coated, and finally assembled with a plastic frame 1213 to form a three-layer structure. In particular, the buffer layer may be a TPU buffer so as to prevent the side plugs 121 from wearing the grooves when sliding in the grooves, and at the same time, reduce the impact noise during the unfolding or recycling process of the covering curtain 1. When the cast aluminum framework can realize high-speed recovery of the covering curtain, the breaking caused by shearing impact is prevented.

Further, limit stopcock 121 buffer layer surface has a plurality of pits, or a plurality of lugs, or a plurality of barb, and pit, lug and barb are buffer material to when avoiding limit stopcock 121 to slide in above-mentioned each recess, the limit stopcock 121 motion process that face contact leads to between buffer layer and the recess inner wall has great resistance, improves the smooth and easy nature of operation.
