[0046] Hereinafter, one of these coating connection structures 300 will be specifically described as an example.

[0047] 2, the covering connection structure 300 includes a fixing seat 310 and an engaging member 320. The fixing seat 310 is provided on the frame 100, and the engaging member 320 is provided on the covering assembly 200. The fixing seat 310 is movably engaged with the engaging member 320, so that the covering assembly 200 is removably attached to the fixing seat 310. In this embodiment, the fixing seat 310 is fixed to the handle member 110, and the engaging member 320 is fixed to the first covering part 230.

[0048] 4 and 5, the fixed seat 310 includes a fixed body 311 and mounting parts 312 connected to both sides of the fixed body 311. In this embodiment, the fixed seat 310 is an integrally molded structure. In another embodiment, the fixed seat 310 can be formed by connecting the fixed body 311 and the mounting parts 312 on both sides, which are independent of each other. The handle member 110 is provided with a recess 111 that matches the shape of the fixed seat 310, and the fixed seat 310 is mounted in the recess 111, and by installing in this way, the riding space occupied by the fixed seat 310 can be reduced, and the whole carrier is more simple and aesthetic. Specifically, the two mounting parts 312 of the fixed seat 310 are respectively mounted in the recess 111 by fastening members (not shown in the drawings).

[0049] 2, 4 and 5, a slide groove 313 is provided on the surface of the fixed body 311 facing away from the handle member 110. The slide groove 313 includes a first groove portion 3131 and two second groove portions 3132 located on both sides of the first groove portion 3131. The first groove portion 3131 is a groove having a substantially parallelogram shape, and one side of the first groove portion 3131 penetrates the opposing upper side of the fixed seat 310, and the first groove portion 3131 further has an abutment side portion 3131a adjacent to the opposing lower side of the fixed seat 310. In this embodiment, the opposing upper side and the abutment side portion 3131a of the fixed seat 310 both extend along the inclination direction of the handle member 110. The other two opposing side walls of the first groove portion 3131 are substantially perpendicular to the horizontal plane, and the second groove portion 3132 is provided on both of these two opposing side walls. The two second grooves 3132 also penetrate the opposing upper sides of the fixed seat 310. That is, the first groove 3131 and the two second grooves 3132 all penetrate the opposing upper sides of the fixed seat 310 to form a T-shaped insertion hole 3133. The insertion hole 3133 is provided opposite the abutment side portion 3131a, and a protrusion 314 is provided in the slide groove 313. In this embodiment, the protrusion 314 is provided at approximately the center of the groove surface of the first groove 3131 facing the engagement member 320.

[0050] 5 and 7, the engaging member 320 is a parallelogram sheet-like structure, and the engaging member 320 can be inserted into the slide groove 313, thereby realizing the attachment of the covering assembly 200 to the frame 100. The engaging member 320 is made of a metal material or a plastic material. In this embodiment, the engaging member 320 and the fixing seat 310 are both made of a plastic material, which is light in weight and low in cost. In another embodiment, the engaging member 320 is made of a metal material, which has high structural strength and prevents the engaging member 320 from wearing out. The engaging member 320 includes two opposing first edges 321 and two opposing second edges 322. The two first edges 321 are parallel to each other, and the two second edges 322 are parallel to each other. The included angle between the adjacent first edges 321 and second edges 322 is greater than 90 degrees or less than 90 degrees. Of course, in other embodiments, the shape of the engaging member 320 is not limited to a parallelogram, and may be other shapes such as a trapezoid or a rectangle, and the present invention is not limited thereto as long as it is movably engageable with the fixed seat 310. A recess 323 that can be engaged and fitted with the protrusion 314 is further provided in the approximate center of the engaging member 320.

[0051] 4 to 6, when the covering assembly 200 needs to be fixed to the frame 100, when the engaging member 320 is inserted into the slide groove 313 through the insertion hole 3133, the two opposing first edges 321 of the engaging member 320 are inserted into the two second grooves 3132, respectively, and as the engaging member 320 is inserted, the engaging member 320 is first pressed by the protrusion 314, causing a certain deformation. When the engaging member 320 is inserted into a predetermined position, that is, when one second edge 322 of the engaging member 320 abuts against the abutment edge 3131a, the protrusion 314 of the fixing seat 310 and the recess 323 of the engaging member 320 are just engaged and fitted, and the engaging member 320 returns to its original shape. Once the engaging member 320 is locked in place, at least a portion of the engaging member 320 is exposed above the insertion opening 3133, thereby making it convenient to remove the covering assembly 200.

[0052] When it is necessary to remove the covering assembly 200 from the frame 100, the portion of the engaging member 320 exposed above the insertion hole 3133 can be grasped to pull the engaging member 320 upward, and the engaging member 320 abuts against the protrusion 314 during the process of being pulled out, causing a certain deformation, so that the engaging member 320 can be removed from the slide groove 313 by the action of an external force. When the engaging member 320 is completely removed from the slide groove 313, the engaging member 320 returns to its original shape. In this way, the covering assembly 200 can be removed from the frame 100, which makes it convenient to clean or replace the covering assembly 200.

[0053] In this embodiment, the insertion hole 3133 is located on the opposing upper side of the abutting edge 3131a, which is advantageous for preventing the engagement member 320 from slipping out of the insertion hole 3133 during use of the covering connection structure 300. Of course, in other embodiments, the insertion hole 3133 may be located at other positions, such as the left side or lower side of the abutting edge 3131a, on the premise of ensuring the close engagement between the engagement member 320 and the fixing seat 310.

[0054] In other embodiments not shown, the installation positions of the protrusion 314 and the recess 323 may be interchangeable, i.e., the protrusion 314 may be provided on the engagement member 320 and the recess 323 may be provided on the fixed seat 310.

[0055] 2 and 7, the engaging member 320 is fixed to the covering assembly 200 by a sewing connection. Specifically, the engaging member 320 is provided with a connecting portion 324, and the covering assembly 200 is sewn to the connecting portion 324. In this embodiment, the engaging member 320 is provided with two connecting portions 324, which are located on both the upper and lower sides of the recessed portion 323, respectively, that is, the two connecting portions 324 are provided close to the two second edges 322 of the engaging member 320, respectively. In this embodiment, the two connecting portions 324 are both parallel to the two second edges 322 of the engaging member 320, and the lengths of the two connecting portions 324 are approximately equal, and the two connecting portions 324 are at least partially offset in a direction parallel to the second edges 322, and such an arrangement can increase the force-receiving area of ​​the suture and improve the strength of the connection of the engaging member 320.

[0056] In addition, the two connecting parts 324 are each provided with a long groove 325, which can accommodate a sewing thread and prevent the sewing thread from affecting the engagement between the protrusion 314 and the recess 323 after it separates the groove surface of the first groove 3131 from the surface of the engaging member 320. In addition, as shown in Figs. 4 and 5, the surface of the engaging member 320 in this embodiment that is overlapped with the covering assembly 200 is flat, and thus, by providing the groove 325, the thickness of the engaging member 320 at the two connecting parts 324 can be reduced, thereby reducing the manufacturing material while facilitating the drilling of the suture and facilitating the connection between the engaging member 320 and the first covering part 230 or another covering assembly 200. As shown in Fig. 2, the connecting part 324 of the engaging member 320 has a number of suture holes 3251. If the engaging member 320 is thick or made of a hard material (e.g., a metal material), a plurality of suture holes 3251 can be pre-installed in the connecting portion 324 before the connecting portion 324 is sewn to the covering assembly 200, so that the suture can easily pass through the covering assembly 200 and the suture holes 3251 to sew and connect the covering assembly 200 and the engaging member 320. If the thickness and material of the engaging member 320 allow a sewing needle (not shown) to pass through, for example, the engaging member 320 is made of a plastic material, the suture holes 3251 do not need to be pre-installed, and the suture can be directly drilled into the covering assembly 200 and the bottom of the groove 325 by the sewing needle (not shown) to sew and connect the covering assembly 200 to the engaging member 320.

[0057] In other embodiments not shown, the number of the connecting portions 324 may be more than two or less than two. The two connecting portions 324 may be disposed adjacent to the two first edges 321 of the engaging member 320 and extend along a direction parallel to the two first edges 321, or the two connecting portions 324 may be disposed in a cross shape, and the present invention is not limited thereto.

[0058] In this embodiment, the lengths of the two connecting parts 324 are approximately the same, and the distances between both ends of the two connecting parts 324 and the two first edges 321 are all approximately the same. The two second edges 322 are at least partially offset, so that the two connecting parts 324 are at least partially offset in a direction parallel to the second edges 322. In other embodiments not shown, the lengths of the two connecting parts 324 may be different. Alternatively, in an embodiment in which the engaging member 320 is rectangular, the two connecting parts 324 are provided with different lengths, or the distances between the two connecting parts 324 and the edges of the rectangle are made different, thereby realizing that the two connecting parts 324 are at least partially offset.

[0059] In this embodiment, at least one of the above-mentioned covering connection structures 300 is provided between the two first covering parts 230 and a part of the frame 100 on the corresponding side. For example, one, two, or three are provided. When there are a plurality of covering connection structures 300, the plurality of covering connection structures 300 are provided at intervals, which is advantageous for improving the stability and reliability of the first covering part 230 being connected to the frame 100, and is advantageous for making the first covering part 230 flatter after being connected to the frame 100, thereby improving the aesthetic appearance of the carrier.

[0060] FIG. 8 shows a perspective view of the carrier provided in the second embodiment of the present invention when the covering assembly 200 is omitted. The carrier may include a frame 100, a covering assembly 200 (please refer to the relevant drawings in the first embodiment) and a covering connection structure 300. The carrier in this embodiment is a modification of the carrier in the first embodiment. If not contradictory, the description in the first embodiment may be referred to for the structure of the members and the connection relationship between the members in this embodiment. The following mainly describes the differences between this embodiment and the first embodiment.

[0061] Referring to FIG. 8, compared with the first embodiment, in this embodiment, the frame 100 is modified, and the difference is mainly in that the structure and connection relationship of the handle part 130 are slightly different. Specifically, the handle part 130 similarly includes a handle body 131 and two pusher levers 132 connected to both ends of the handle body 131, but the bottom ends of the two pusher levers 132 are not connected to the opposing rear sides of the seat part 120 as in the first embodiment. In this embodiment, the bottom ends of the two pusher levers 132 are respectively connected to the tips of the handle members 110 on the same side. When the frame 100 is in an open state, the included angle between each of the two pusher levers 132 and the handle member 110 on the same side is approximately 180 degrees, in other words, each of the two pusher levers 132 and the handle member 110 on the same side can be regarded as extending along the same straight line.

[0062] 8 to 10, in this embodiment, the covering connection structure 300 is further modified. Similarly, one of the covering connection structures 300 will be specifically described below as an example.

[0063] In this embodiment, the covering connection structure 300 includes a fixed seat 310 and an engaging member 320. The fixed seat 310 is similarly disposed on the frame 100, and the engaging member 320 is similarly disposed on the covering assembly 200. In one embodiment, one of the fixed seat 310 and the engaging member 320 is provided with a position limiting locking protrusion 315, and the other of the fixed seat 310 and the engaging member 320 is provided with a mounting groove 326, and one end of the mounting groove 326 penetrates the fixed seat 310 or the engaging member 320, and one end of the mounting groove 326 penetrates the fixed seat 310 or the engaging member 320. In this way, the mounting groove 326 is slidably fitted outside the position limiting locking protrusion 315 to realize the movable engagement between the fixed seat 310 and the engaging member 320.

[0064] Note that the above description "one of the fixed seat 310 and the engaging member 320 is provided with the position limiting locking protrusion 315, and the other of the fixed seat 310 and the engaging member 320 is provided with the mounting groove 326" includes two embodiments. For example, when the fixed seat 310 is provided with the position limiting locking protrusion 315, the engaging member 320 is provided with the mounting groove 326, and one end of the mounting groove 326 penetrates the engaging member 320. Alternatively, when the engaging member 320 is provided with the position limiting locking protrusion 315, the fixed seat 310 is provided with the mounting groove 326, and one end of the mounting groove 326 penetrates the fixed seat 310. Even if the fixed seat 310 is provided with the position limiting locking protrusion 315 or the mounting groove 326 , the mounting groove 326 or the position limiting locking protrusion 315 of the engagement member 320 can both engage with the position limiting locking protrusion 315 or the mounting groove 326 of the fixed seat 310 .

[0065] Specifically, in this embodiment, the fixed seat 310 is provided with a position limiting locking protrusion 315, the engaging member 320 is provided with an attachment groove 326, and one end of the attachment groove 326 penetrates the engaging member 320 to form an attachment opening 3263. In this manner, the engaging member 320 can be slidably fitted outside the position limiting locking protrusion 315 by using the attachment groove 326 through the attachment opening 3263, thereby realizing a detachable connection between the engaging member 320 and the fixed seat 310, and finally the covering assembly 200 is detachably attached to the frame 100.

[0066] In addition, compared to the first embodiment, the recessed portion 111 may be omitted in the frame 100 in this embodiment, and the fixing base 310 is provided with a mounting hole 316, which is directly attached to the frame 100 by a fastening member. Of course, in other embodiments, the frame 100 is similarly provided with a recessed portion 111 at the connection portion of the frame 100 with the fixing base 310 as shown in the first embodiment, and the mounting hole 316 in the fixing base 310 is for the passage of a fastening member, whereby the fixing base 310 is attached within the recessed portion 111 of the frame 100.

[0067] 8 and 9, in this embodiment, the engagement member 320 is provided with a connection through-hole 328, through which a webbing (not shown) or the like passes. The webbing that passes through the connection through-hole 328 is used to connect to the covering assembly 200. The webbing that passes through the connection through-hole 328 may be fixedly connected to the covering assembly 200 or detachably connected thereto. For example, when the webbing and the covering assembly 200 are fixedly connected to each other, the connecting manner between the webbing and the covering assembly 200 includes, but is not limited to, sewing or bonding with an adhesive. For example, in the case of sewing, one end of the webbing passes through the connection through-hole 328 and overlaps with the other end, and both ends of the webbing are connected to the covering assembly 200 by sewing. Furthermore, for example, when the webbing and the covering assembly 200 are detachably connected, the connecting manner between them includes, but is not limited to, tying the webbing to the covering assembly 200 or using other connecting structures (for example, a pair of snap buttons or a pair of adhesive buttons, etc.) Of course, in other embodiments, the engaging member 320 may be provided with the connecting portion 324 in the first embodiment, and the connecting through hole 328 may be omitted, and thus the connection between the engaging member 320 and the covering assembly 200 can be realized.

[0068] 9 and 10, in one embodiment, the shape of the connection through hole 328 is not limited and may be, for example, a circular hole or an elongated hole. The installation position of the connection through hole 328 in the engagement member 320 is also not specifically limited. For example, the connection through hole 328 may be located at the lower end of the engagement member 320 and close to the mounting opening 3263. When the connection through hole 328 is an elongated hole, the extension direction thereof intersects with the direction in which the position limiting locking protrusion 315 slides in the mounting groove 326. 9 to 11, in one embodiment, the position limiting locking protrusion 315 includes a first protrusion 3151 and a second protrusion 3152 that are connected to each other, the second protrusion 3152 protruding outward from the outer periphery of the first protrusion 3151 to form a position limiting edge 3153, the first protrusion 3151 is connected to the fixing seat 310, and the second protrusion 3152 is spaced from the fixing seat 310 to form a position limiting recess 3154. In one embodiment, the mounting groove 326 includes a first groove body 3261 and a second groove body 3262 that is provided on the outer periphery of the first groove body 3261 and communicates with the first groove body 3261, and the first groove body 3261 and the second groove body 3262 both penetrate one end of the engaging member 320 to form a T-shaped mounting opening 3263. Specifically, the mounting groove 326 has a first wall 3265, a second wall 3266, and a third wall 3267. The first wall 3265 and the second wall 3266 face each other in a direction perpendicular to the sliding direction of the position limiting locking protrusion 315, and are spaced apart from each other, and the first wall 3265 is located on one side of the second wall 3265 close to the fixed seat 310. The third wall 3267 extends in a direction perpendicular to the sliding direction of the position limiting locking protrusion 315 to connect the first wall 3265 and the second wall 3266. The first groove 3261 penetrates the first wall 3265 in a direction perpendicular to the sliding direction of the position limiting locking protrusion 315. The first wall 3265, the second wall 3266, and the third wall 3267 together define a second groove 3262. In this way, when the mounting groove 326 engages with the position limiting locking protrusion 315, the position limiting edge 3153 is restricted in position within the second groove body 3262, and the side wall (first wall body 3265) of the second groove body 3262 is restricted in position within the position limiting recess 3154.In this way, the position limit locking protrusion 315 can be detached from the mounting groove 326 only through the mounting port 3263, thereby preventing the engagement member 320 and the fixed seat 310 from separating along the protruding direction of the position limit locking protrusion 315 after the engagement member 320 is connected to the fixed seat 310.

[0069] The first convex portion 3151 and the second convex portion 3152 may be fixedly connected to each other, for example, they may be integrally molded and welded or bonded. Naturally, the first convex portion 3151 and the second convex portion 3152 may be detachably connected to each other, for example, by engagement. Similarly, the connection relationship between the first convex portion 3151 and the fixed seat 310 can be referenced to the connection relationship between the first convex portion 3151 and the second convex portion 3152, so no specific limitations are imposed here.

[0070] In this embodiment, the mounting opening 3263 is provided downward along the length direction of the handle tube 132 or the handle member 110. Of course, in other embodiments, the mounting opening 3263 can be oriented in other directions, provided that the tightness of the engagement between the engaging member 320 and the fixed seat 310 is guaranteed. For example, the mounting opening 3263 may be provided forward or backward along the movement of the carrier.

[0071] Specifically, in this embodiment, the first convex portion 3151 and the second convex portion 3152 both have a circular structure, and thus the position limiting edge portion 3153 and the position limiting recess portion 3154 both have an annular structure. The first groove body 3261 and the second groove body 3262 both include an elongated first groove segment 3264a and an arc-shaped second groove segment 3264b. One end of the first groove segment 3264a communicates with the second groove segment 3264b, and the above-mentioned mounting port 3263 is formed at the other end of the first groove segment 3264a. More specifically, the first groove segment 3264a of the first groove body 3261 is connected to the second groove segment 3264b of the first groove body 3261, the first groove segment 3264a of the second groove body 3262 is connected to the second groove segment 3264b of the second groove body 3262, the first groove segment 3264a of the first groove body 3261 is connected to the first groove segment 3264a of the second groove body 3262, and the second groove segment 3264b of the first groove body 3261 is connected to the second groove segment 3264b of the second groove body 3262, and the first groove segment 3264a of the first groove body 3261 and the first groove segment 3264a of the second groove body 3262 together form an attachment opening 3263 having a T-shaped cross section. In this way, when the engaging member 320 engages with the position limiting locking protrusion 315 in the fixed seat 310 via the mounting groove 326, the position limiting edge 3153 is restricted in position within the second groove segment 3264b of the second groove body 3262, and the first protrusion 3151 is positioned within the second groove segment 3264b of the first groove body 3261.

[0072] More specifically, the first wall 3265, the second wall 3266, and the third wall 3267 each include an elongated wall portion and an arc-shaped wall portion. The first groove segment 3264a of the first groove 3261 penetrates the elongated wall portion of the first wall 3265 in a direction perpendicular to the sliding direction of the position limiting locking protrusion 315, and the second groove segment 3264b of the first groove 3261 penetrates the arc-shaped wall portion of the first wall 3265 in a direction perpendicular to the sliding direction of the position limiting locking protrusion 315. The elongated wall portions of the first wall 3265, the second wall 3266, and the third wall 3267 together define the first groove segment 3264a of the second groove 3262. The arcuate wall portions of the first wall 3265 , the second wall 3266 and the third wall 3267 together define a second groove segment 3264 b of the second groove body 3262 .

[0073] As the engaging member 320, the position limiting locking protrusion 315 rotates into the second groove segment 3264b of the first groove body 3261 and the second groove body 3262, so that the engaging member 320 can rotate relative to the fixed seat 310. In other words, when the engaging member 320 is connected to the fixed seat 310, the engaging member 320 may be operated to rotate relative to the fixed seat 310. Specifically, the engaging member 320 can rotate relative to the fixed seat 310 around the central axis of the second protrusion 3152. When the first covering part 230 is connected to the frame 100, the first covering part 230 can be adjusted by rotating the engaging member 320, thereby avoiding the occurrence of a twisting phenomenon in the first covering part 230. As can be seen, the engaging member 320 can be rotated relative to the fixed seat 310, so that the flexibility of the fixed connection of the first covering part 230 can be improved. When adjusting the tilt angle at the backrest portion, the backrest portion may move so that the covering assembly 200 moves with it, and the portion of the covering assembly 200 connected to the engagement member 320 may rotate to a certain extent, at which time the engagement member 320 can rotate relative to the fixed seat 310, thereby reducing twisting and wrinkling of the covering assembly 200 at the engagement member 320.

[0074] In this embodiment, the first convex portion 3151 and the second convex portion 3152 are provided coaxially, that is, the central axes of both are collinear. Furthermore, the mounting hole 316 passes through the first convex portion 3151, the second convex portion 3152, and the fixing seat 310 in this order, and the axis of the mounting hole 316 is located on the central axis of the first convex portion 3151 and the second convex portion 3152. The radius of a circle formed by the arc of the second groove segment 3264b of the second groove body 3262 is equal to or greater than the radius of the second convex portion 3152, and the radius of a circle formed by the arc of the second groove segment 3264b of the first groove body 3261 is equal to or greater than the radius of the first convex portion 3151. In this way, it becomes easier for the second protrusion 3152 to enter into the second groove segment 3264b of the second groove body 3262, and it becomes easier for the first protrusion 3151 to enter into the second groove segment 3264b of the first groove body 3261.

[0075] 10, in one embodiment, the engaging member 320 is provided with a position limiting structure 327, and when the engaging member 320 is operated to engage the mounting groove 326 with the position limiting locking protrusion 315, the position limiting locking protrusion 315 moves from the mounting opening 3263 to the inside of the mounting groove 326 against the position limiting structure 327. Specifically, the position limiting structure 327 includes a position limiting portion 3271 and an openwork portion 3272. The position limiting portion 3271 is provided on one side or both opposite side walls of the first groove body 3261, and more specifically, the position limiting portion 3271 can be formed on the surface of the first wall body 3265 facing the first groove body 3261, and the position limiting portion 3271 can be in the form of a position limiting convex surface formed on the surface of the first wall body 3265 facing the first groove body 3261. An openwork portion 3272 is provided at a position corresponding to the position limiting portion 3271 on one side or on both opposing side walls of the first groove body 3261, more specifically, the openwork portion 3272 is provided on the surface of the first wall body 3265 facing the fixed seat 310, and penetrates the first wall body 3265 in a direction perpendicular to the sliding direction of the position limiting locking protrusion 315. When the position limiting portion 3271 is pressed by the position limiting locking protrusion 315, the position limiting portion 3271 moves in the direction of the openwork portion 3272, whereby the position limiting portion 3271 is elastically deformed and the openwork portion 3272 becomes smaller.

[0076] Specifically, in this embodiment, two position limiting portions 3271 are provided, and the two position limiting portions 3271 are located on two opposing side walls of the first groove segment 3264a of the first groove body 3261, respectively, and more specifically, on two opposing surfaces of the first wall body 3265 toward the first groove body 3261. In addition, one openwork portion 3272 is provided on each side of the mounting opening 3263 along the width direction of the mounting opening 3263. When it is necessary to connect the engaging member 320 to the fixing seat 310, after the mounting opening 3263 of the engaging member 320 is aligned with the position limiting locking protrusion 315, the engaging member 320 can be further operated (e.g., pushed or pulled) along a diagonally downward direction, and thus the engaging member 320 can be moved relative to the fixing seat 310, that is, it can be considered that the position limiting locking protrusion 315 can be moved from the mounting opening 3263 to the inside of the mounting groove 326 relative to the engaging member 320. In the process of the position limiting locking protrusion 315 entering the mounting groove 326, the second protrusion 3152 is first inserted into the first groove segment 3264a of the second groove body 3262, and at the same time the first protrusion 3151 is inserted into the first groove segment 3264a of the first groove body 3261. When the first protrusion 3151 abuts against the two position limiting portions 3271, the position limiting portions 3271 gradually move in a direction approaching the openwork portions 3272, and the position limiting portions 3271 are elastically deformed, and the openwork portions 3272 provide the space necessary for the movement of the position limiting portions 3271. When the first protrusion 3151 passes through the first groove segment 3264a and enters the second groove segment 3264b, the two position limiting portions 3271 return to their original positions to limit the first protrusion 3151 within the second groove segment 3264b of the first groove body 3261. In this way, after the engaging member 320 is connected to the fixed seat 310, if there is no external force or the external force is small, the engaging member 320 and the fixed seat 310 remain relatively fixed, preventing the position limiting locking protrusion 315 from easily exiting from the mounting groove 326 through the mounting hole 3263. When it is necessary to remove the engaging member 320 from the fixed seat 310, the engaging member 320 can be pushed or pulled in the opposite direction (i.e., in a substantially obliquely upward direction), so that in the process of the engaging member 320 moving relative to the fixed seat 310, the position limiting locking protrusion 315 exits from the mounting hole 3263 of the mounting groove 326.In this process, the first convex portion 3151 abuts against the position limiting portion 3271 again, so that the position limiting portion 3271 gradually moves in a direction approaching the openwork portion 3272, and the position limiting portion 3271 is deformed to a certain extent. After the first convex portion 3151 passes over the position limiting portion 3271, the openwork portion 3272 and the position limiting portion 3271 return to their original shapes and positions.

[0077] 10, in one embodiment, a rib 329 is provided on one side of the engaging member 320 facing the mounting groove 326. For example, the rib 329 may be provided on the surface of the first wall 3265 facing the fixed seat 310. When the engaging member 320 is slidably fitted outside the position limit locking protrusion 315 through the mounting groove 326, the rib 329 on the engaging member 320 ensures that the engaging member 320 is in close contact with the end face of the position limit locking protrusion 315 (i.e., the end face of the second protrusion 3152 facing away from the fixed seat 310). The rib 329 can effectively prevent the problem of unstable engagement between the fixed seat 310 and the engaging member 320 caused by the end face of the position limit locking protrusion 315 not being fully overlapped with the groove wall of the mounting groove 326. In other words, the rib 329 can effectively improve the reliability of the engaging member 320 being engaged with the position limit locking protrusion 315.

[0078] In one embodiment, the above-mentioned covering connection structure 300 is provided between the two first covering parts 230 and the handle member 110 and / or the pusher lever 132 on the corresponding side. Specifically, in this embodiment, as shown in Fig. 8, the covering connection structure 300 is provided between each of the two first covering parts 230 and the handle member 110 and the pusher lever 132 on the corresponding side. In this way, the reliability of the connection between the first covering part 230 and the frame 100 can be improved, so that the first covering part 230 becomes flatter after being connected to the frame 100, which is advantageous to improving the aesthetic appearance of the carrier.

[0079] 12 shows a perspective view of the carrier provided in the third embodiment of the present invention when the covering assembly 200 is omitted. The carrier includes a frame 100, a covering assembly 200 (see the relevant drawings of the first embodiment) and a covering connection structure 300. The carrier in this embodiment is a modification of the carrier in the second embodiment. If not inconsistent, the structure of the members and the connection relationship between the members in this embodiment should be referred to the description in the second embodiment. The following mainly describes the differences between this embodiment and the second embodiment.

[0080] 13 to 15, in this embodiment, the first convex portion 3151 and the second convex portion 3152 both have an elongated structure. The first convex portion 3151 and the second convex portion 3152 both extend along the length direction of the handle member 110 and / or the pusher lever 132. Along the extending direction of the first convex portion 3151 and the second convex portion 3152, the tips of the first convex portion 3151 and the second convex portion 3152 are arc-shaped. The second groove segment 3264b of the second groove body 3262 has an abutment edge portion 3131a provided opposite the mounting opening 3263. When the mounting groove 326 is engaged with the position limiting locking protrusion 315, the tip of the second protrusion 3152 abuts against the abutting edge 3131a, and the position limiting edge 3153 is positionally limited within the first groove segment 3264a and the second groove segment 3264b of the second groove body 3262. Specifically, in this embodiment, the abutting edge 3131a is arc-shaped, and the arc degree is the same as the arc degree of the outer edge of the tip of the second protrusion 3152. Since the tips of the first protrusion 3151 and the second protrusion 3152 are arc-shaped, it is advantageous for the position limiting locking protrusion 315 to be quickly and accurately introduced into the inside of the mounting groove 326 from the mounting opening 3263, and the speed of connection between the engagement member 320 and the fixed seat 310 is improved. In addition, the tip of the first protrusion 3151 has an arc shape, which is advantageous in improving the smoothness of the position limiting portion 3271 moving in the direction approaching the openwork portion 3272 when it abuts against the position limiting portion 3271. In addition, in other embodiments, the second groove segment 3264b may have other shapes, for example, the second groove segment 3264b and the first groove segment 3264a are both similarly long structures, and the specific shapes are not limited here. In order to ensure the stability of the position limiting locking protrusion 315 being locked in the mounting groove 326 and to prevent the engagement member 320 from easily coming off the fixed seat 310, in this embodiment, as shown in FIG. 13, the first protrusion 3151 is provided with a recessed opening 31511 recessed inward. When the mounting groove 326 is engaged with the position limiting locking protrusion 315 , the recessed opening 31511 is used to be engaged and fitted with the position limiting portion 3271 of the position limiting structure 327 .

[0081] When the position limiting locking protrusion 315 enters the mounting groove 326, the second protrusion 3152 is first inserted into the first groove segment 3264a of the second groove body 3262, and at the same time, the first protrusion 3151 is inserted into the first groove segment 3264a of the first groove body 3261. When the first protrusion 3151 abuts against the two position limiting portions 3271, the position limiting portion 3271 gradually moves in a direction approaching the openwork portion 3272, and the position limiting portion 3271 elastically deforms, and the openwork portion 3272 provides the space necessary for the movement of the position limiting portion 3271. When the engaging member 320 moves to a predetermined position, that is, when the abutting edge 3131a of the second groove body 3262 of the engaging member 320 abuts against the tip of the second protrusion 3152, the position limiting portion 3271 on the side wall of the first groove body 3261 is exactly engaged and fitted into the recessed opening 31511 of the first protrusion 3151, and at this time, the position limiting portion 3271 and the openwork portion 3272 both return to their original positions and shapes. In this way, after the engaging member 320 is connected to the fixed seat 310, if there is no external force or the external force is small, the engaging member 320 and the fixed seat 310 remain relatively fixed, which prevents the position limiting locking protrusion 315 from easily exiting from the mounting groove 326 through the mounting opening 3263. Similarly, in the process of removing the engaging member 320 from the fixed seat 310, the first protrusion 3151 pushes the position limiting portion 3271 during the movement process, gradually moving it in a direction approaching the openwork portion 3272, and the position limiting portion 3271 retreats from the recessed opening 31511. When the first protrusion 3151 and the position limiting portion 3271 are separated, the openwork portion 3272 and the position limiting portion 3271 return to their original shapes and positions.

[0082] 13 and 14, in order to improve the stability and reliability of the connection between the engagement member 320 and the covering assembly 200, in this embodiment, the connection through-hole 328 is an elongated hole, and the extension direction of the connection through-hole 328 is approximately parallel to the direction in which the position limiting locking protrusion 315 slides relatively into the mounting groove 326. In order to avoid interference when the engagement member 320 is connected to the covering assembly 200 through the connection through-hole 328, in this embodiment, the connection through-hole 328 can be regarded as being located at the side of the engagement member 320, and the connection through-hole 328 is parallel to the first groove segment 3264a and located outside the first groove segment 3264a. Of course, in other embodiments, the connection through-hole 328 may have other shapes. For the position of the connection through-hole 328, please refer to the position of the connection through-hole 328 in the second embodiment.

[0083] Specifically, in this embodiment, as shown in Figures 12 and 13, the fixed base 310 is provided with two mounting holes 316 along its length, which is advantageous in improving the stability of the fixed base 310 when attached to the frame 100. More specifically, compared to the first embodiment, a recess 111 is also provided at a portion of the frame 100 in this embodiment that is connected to the fixed base 310, and the two mounting holes 316 are for a fastening member to pass through and attach the fixed base 310 to the recess 111 of the frame 100. Of course, in other embodiments, the recess 111 in the frame 100 may be omitted.
