Two front wheel assemblies 170 are connected to the bottom end of the footrest plate 150. The two front leg support members 160a are connected to the opposing front sides of the seat portion 120. The canopy frame 140 also has a roughly U-shaped rod structure, and the two ends of the canopy frame 140 are each connected to the tips of the two handle members 110. There are two rear leg support members 160b. The ends of the two rear leg support members 160b are each connected to the lower part of two handle members 110, and the bottom ends of the two rear leg support members 160b are each connected to two rear wheel assemblies 180. Furthermore, the frame 100 may further include a backrest (not shown, e.g., a backrest plate), which is connected to the seat portion 120 or the handle member 110, and the backrest is adjustable to different inclination angles relative to the seat portion 120, so that the occupant's back can rest against the backrest at an appropriate inclination angle.
[0042] Specifically, as shown in Figure 1, the cover assembly 200 has a fabric structure and includes a seat cover 210, a backrest cover 220, a first cover 230, and a second cover 240. There are two first cover sections 230, each connected to both sides of the backrest cover 220, and the second cover sections 240 are connected to the tops of the two first cover sections 230 and the top of the backrest cover 220, respectively. To connect the cover assembly 200 to the frame 100, each first cover section 230 in this embodiment is detachably connected to a corresponding handle member 110, the seat cover 210 may be connected to the seat section 120, and the top of the second cover section 240 may be connected to the support section 190 by means of a fastener or the like. Of course, in other embodiments, the connection position between the cover assembly 200 and the frame 100 can be adjusted according to actual needs. In this embodiment, the seat cover portion 210, the backrest cover portion 220, and the first and second cover portions 230 and 220 on both sides can be fixed and connected by stitching, thereby giving the cover assembly 200 a one-piece structure. Of course, in other embodiments, the seat cover portion 210, the backrest cover portion 220, and the first and second cover portions 230 and 240 on both sides may be detachably connected to each other by a structure such as a fastener, depending on the actual needs, and are not limited thereto.
[0043] To improve the comfort of the occupants, a seat cushion 410 is provided on the seat section 120, and a back cushion 420 is connected to the seat cushion 410. When the covering assembly 200 is connected to the frame 100, the seat section covering 210 is located below the seat cushion 410, and the seat cushion 410 may be further fixed to the seat section 120, and the backrest covering 220 is located behind the back cushion 420, and the back cushion 420 is provided with a restraint protection structure (e.g., a seat belt).
[0044] Furthermore, as a method of connecting the seat cover portion 210 and the seat portion 120, a pocket (not shown) may be provided at the bottom of the front end of the seat cover portion 210 to enclose the front end of the seat portion 120. The seat cushion 410 may also be provided with a pocket (not shown) to overlap and enclose the front ends of the seat cover portion 210 and the seat portion 120, or it may be connected to the seat cover portion 210 by another structure without a pocket.
[0045] In this embodiment, as shown in Figures 1 and 2, a connecting structure 300 for the covering is provided between the two first covering portions 230 and the corresponding handle members 110. Naturally, in other embodiments, the connecting structure 300 for the covering is not limited to being provided between the first covering portion 230 and the handle members 110, but may be provided, for example, between the sheet portion covering portion 210 and the sheet portion 120, or between the second covering portion 240 and the canopy frame 140, and the present invention is not limited thereto.
[0046] The following will provide a specific explanation using one of the covering structures, 300, as an example.
[0047] Specifically, as shown in Figure 2, the sheathing connection structure 300 includes a fixed seat 310 and an engaging member 320. The fixed seat 310 is provided on the frame 100, and the engaging member 320 is provided on the sheathing assembly 200. The fixed seat 310 is movably engaged with the engaging member 320, so that the sheathing assembly 200 is detachably attached to the fixed seat 310. In this embodiment, the fixed seat 310 is fixed to the handle member 110, and the engaging member 320 is fixed to the first sheathing portion 230.
[0048] Furthermore, as shown in Figures 4 and 5, the fixed seat 310 includes a fixed body 311 and mounting portions 312 connected to both sides of the fixed body 311. In this embodiment, the fixed seat 310 is a one-piece molded structure. In other embodiments, the fixed seat 310 can be formed by connecting a fixed body 311 and mounting portions 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 within the recess 111. By installing it in this way, the riding space occupied by the fixed seat 310 can be reduced, and the entire carrier can be made simpler and more aesthetically pleasing. Specifically, the two mounting portions 312 of the fixed seat 310 are each attached within the recess 111 by a fastening member (not shown in the drawings).
[0049] Furthermore, as shown in Figures 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 3131 and two second grooves 3132 located on both sides of the first groove 3131. The first groove 3131 is a substantially parallelogram-shaped groove, one side of which penetrates the opposing upper side of the fixed seat 310, and the first groove 3131 further has a contact edge 3131a that is close to the opposing lower side of the fixed seat 310. In this embodiment, both the opposing upper side and the contact edge 3131a of the fixed seat 310 extend along the inclination direction of the handle member 110. The other two opposing side walls of the first groove 3131 are substantially perpendicular to the horizontal plane, and the second grooves 3132 are provided on both of these 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 both penetrate the opposing upper sides of the fixed seat 310 to form a T-shaped insertion opening 3133. The insertion opening 3133 is provided opposite the contact edge 3131a, and a projection 314 is provided within the slide groove 313. In this embodiment, the projection 314 is provided approximately at the center of the groove surface of the first groove 3131 facing the engaging member 320.
[0050] Furthermore, as shown in Figures 5 and 7, the engaging member 320 is a parallelogram-shaped sheet structure and can be inserted into the slide groove 313, thereby enabling the attachment of the cover assembly 200 to the frame 100. The engaging member 320 is made of metal or plastic. In this embodiment, both the engaging member 320 and the fixing seat 310 are made of plastic, resulting in light weight and low cost. In other embodiments, the engaging member 320 is made of metal, which has high structural strength and avoids wear of the engaging member 320. 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 angle between adjacent first edges 321 and second edges 322 is greater than 90 degrees or less than 90 degrees. Naturally, in other embodiments, the shape of the engaging member 320 is not limited to a parallelogram, but may be other shapes such as a trapezoid or quadrilateral, and the present invention is not limited thereto as long as it can be movably engaged with the fixed seat 310. A recess 323 is further provided in the approximate middle of the engaging member 320, which can engage and fit with the projection 314.
[0051] Thus, as shown in Figures 4 to 6, when it is necessary to fix the covering assembly 200 to the frame 100, when the engaging member 320 is inserted into the slide groove 313 through the insertion opening 3133, the two opposing first edges 321 of the engaging member 320 are each inserted into the two second grooves 3132, and as the engaging member 320 is inserted, it is first pressed against the projection 314, causing a certain deformation. When the engaging member 320 is inserted into the predetermined position, that is, when one of the second edges 322 of the engaging member 320 comes into contact with the contact edge 3131a, the projection 314 of the fixing seat 310 and the recess 323 of the engaging member 320 engage and fit together, and the engaging member 320 returns to its original shape. Once the engaging member 320 is engaged in the predetermined position, at least a portion of the engaging member 320 is exposed above the insertion opening 3133, thereby facilitating the removal of 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 opening 3133 can be grasped and the engaging member 320 can be pulled upward. During the pulling process, the engaging member 320 comes into contact with the projection 314, causing a certain deformation, which allows the engaging member 320 to retract from the slide groove 313 due to external force. Once the engaging member 320 has completely retracted from the slide groove 313, it returns to its original shape. In this way, the covering assembly 200 can be removed from the frame 100, thereby facilitating cleaning or replacement of the covering assembly 200.
[0053] In this embodiment, the insertion opening 3133 is located on the upper side opposite the contact edge 3131a, which is advantageous in preventing the engaging member 320 from slipping out of the insertion opening 3133 during use of the connecting structure 300 for the covering. Naturally, in other embodiments, the insertion opening 3133 may be located in other positions, such as to the left or below the contact edge 3131a, provided that the tight fit between the engaging member 320 and the fixed seat 310 is ensured.
[0054] In other embodiments not shown, the mounting positions of the projection 314 and the recess 323 are interchangeable; that is, the projection 314 may be provided on the engaging member 320 and the recess 323 may be provided on the fixing seat 310.
[0055] Furthermore, as shown in Figures 2 and 7, the engaging member 320 is fixed to the covering assembly 200 by a suture connection. Specifically, the engaging member 320 is provided with a connecting portion 324, and the covering assembly 200 is sutured to the connecting portion 324. In this embodiment, the engaging member 320 is provided with two connecting portions 324, which are located on the upper and lower sides of the recessed portion 323, that is, the two connecting portions 324 are located close to the two second edges 322 of the engaging member 320. In this embodiment, both connecting portions 324 are parallel to the two second edges 322 of the engaging member 320, and the lengths of the two connecting portions 324 are approximately equal. The two connecting portions 324 are at least partially offset in a direction parallel to the second edges 322, and by installing them in this manner, the force-receiving area of the sutures can be increased, and the strength of the connection of the engaging member 320 can be improved.
[0056] Furthermore, both connecting portions 324 are provided with elongated grooves 325, which allow the sewing thread to be stored, preventing the sewing thread from affecting the engagement between the projection 314 and the recess 323 after it has separated the groove surface of the first groove portion 3131 from the surface of the engaging member 320. Also, as shown in Figures 4 and 5, the surface of the engaging member 320 that is superimposed on the covering assembly 200 in this embodiment is flat. By providing the grooves 325 in this way, the thickness of the engaging member 320 at the locations of the two connecting portions 324 can be reduced, thereby reducing the amount of manufacturing material, while making it easier to insert the suture thread and facilitating the connection between the engaging member 320 and the first covering portion 230 or other covering assembly 200. As shown in Figure 2, the connecting portion 324 of the engaging member 320 has a plurality of suture holes 3251. Furthermore, if the engaging member 320 is thick or made of a hard material (for example, metal), multiple suture holes 3251 can be pre-installed in the connecting portion 324 before it is sutured to the covering assembly 200, thereby facilitating the suture thread to pass through the covering assembly 200 and the suture holes 3251 to suture and connect the covering assembly 200 and the engaging member 320. If the thickness and material of the engaging member 320 allow for the penetration of a sewing needle (not shown), and if it is made of a plastic material, for example, the suture holes 3251 do not need to be pre-installed, and the suture thread can be directly drilled into the covering assembly 200 and the bottom of the groove 325 by a sewing needle (not shown) to suture and connect the covering assembly 200 to the engaging member 320.
[0057] In other embodiments not shown, there may be more than two or fewer connection portions 324. The two connection portions 324 may be positioned close to the two first edges 321 of the engaging member 320 and extending along a direction parallel to the two first edges 321, or the two connection portions 324 may be positioned intersecting, and the present invention is not limited thereto.
[0058] In this embodiment, the lengths of the two connecting portions 324 are approximately the same, and the distances between both ends of the two connecting portions 324 and the two first edges 321 are also approximately the same. Since the two second edges 322 are provided at least partially offset, the two connecting portions 324 are provided at least partially offset in a direction parallel to the second edges 322. In other embodiments not shown, the lengths of the two connecting portions 324 may be different. Alternatively, in embodiments where the engaging member 320 is rectangular, the two connecting portions 324 are provided at least partially offset by setting them to different lengths or by varying the distances between the two connecting portions 324 and the edges of the rectangle.
[0059] In this embodiment, at least one of the above-described covering connection structures 300 is provided between the two first covering portions 230 and a portion of the frame 100 on the corresponding side. For example, one, two, or three such structures may be provided. When there are multiple covering connection structures 300, the multiple covering connection structures 300 are provided at intervals, which is advantageous in improving the stability and reliability of the connection of the first covering portions 230 to the frame 100, and is also advantageous in making the first covering portions 230 flatter after they are connected to the frame 100, thereby improving the aesthetic appearance of the carrier.
[0060] Figure 8 shows a perspective view of the carrier provided in the second embodiment of the present invention, with the sheathing assembly 200 omitted. This carrier may include a frame 100, a sheathing assembly 200 (see the relevant drawings in the first embodiment), and a sheathing connection structure 300. The carrier in this embodiment is a variation of the carrier in the first embodiment. Where there is no inconsistency, the structure of the members and the connection relationships between members in this embodiment can be described by referring to the description in the first embodiment. The differences between this embodiment and the first embodiment will be described below.
[0061] Referring to Figure 8, compared to the first embodiment, the frame 100 is deformed in this embodiment, and the main difference is that the structure and connection relationship of the handle portion 130 are slightly different. Specifically, the handle portion 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 portion 120 as in the first embodiment. In this embodiment, the bottom ends of the two pusher levers 132 are each connected to the tip of the handle member 110 on the same side. When the frame 100 is in the open state, the 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, it can be considered that each of the two pusher levers 132 and the handle member 110 on the same side extend along the same straight line.
[0062] Referring to Figures 8 to 10, the connection structure 300 of the covering is further modified in this embodiment. Similarly, one of the connection structures 300 of the covering will be described in detail 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 positioned on the frame 100, and the engaging member 320 is similarly positioned on the covering assembly 200. In one embodiment, a position-limiting locking projection 315 is provided on one of the fixed seat 310 and the engaging member 320, and a mounting groove 326 is provided on the other of the fixed seat 310 and the engaging member 320, with one end of the mounting groove 326 passing through the fixed seat 310 or the engaging member 320, and the other end of the mounting groove 326 passing through the fixed seat 310 or the engaging member 320. In this way, the mounting groove 326 is slidably fitted outside the position-limiting locking projection 315 to achieve movable engagement between the fixed seat 310 and the engaging member 320.
[0064] The above statement, "A position-restricting locking projection 315 is provided on one of the fixed seat 310 and the engaging member 320, and a mounting groove 326 is provided on the other of the fixed seat 310 and the engaging member 320," includes two embodiments. For example, if the fixed seat 310 is provided with the position-restricting locking projection 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, if the engaging member 320 is provided with the position-restricting locking projection 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 a position-restricting locking projection 315 or a mounting groove 326, the mounting groove 326 or the position-restricting locking projection 315 on the engaging member 320 can both engage with the position-restricting locking projection 315 or the mounting groove 326 on the fixed seat 310.
[0065] Specifically, in this embodiment, the fixed seat 310 is provided with a position-restricting locking projection 315, and the engaging member 320 is provided with a mounting groove 326. One end of the mounting groove 326 penetrates the engaging member 320 to form a mounting opening 3263. In this way, the engaging member 320 can be slidably fitted outside the position-restricting locking projection 315 using the mounting groove 326 via the mounting opening 3263, thereby enabling a removable connection between the engaging member 320 and the fixed seat 310, and finally the covering assembly 200 can be removablely attached to the frame 100.
[0066] Compared to the first embodiment, the recessed portion 111 in the frame 100 in this embodiment may be omitted, and a mounting hole 316 is provided in the fixing seat 310, and the mounting hole 316 is directly attached to the frame 100 by a fastening member. Naturally, in other embodiments, as shown in the first embodiment, the frame 100 is similarly provided with a recessed portion 111 at the connection point with the fixing seat 310, and the mounting hole 316 in the fixing seat 310 is for the fastening member to pass through, thereby attaching the fixing seat 310 to the recessed portion 111 of the frame 100.
[0067] Referring to Figures 8 and 9, in this embodiment, the engaging member 320 is provided with a connecting through-hole 328, which is for passing webbing (not shown) through. The webbing that passes through the connecting through-hole 328 is used to connect to the covering assembly 200. The webbing that passes through the connecting through-hole 328 may be fixedly connected to the covering assembly 200 or detachably connected. For example, if the webbing and the covering assembly 200 are fixedly connected, the method of connection between them may include, but is not limited to, sutures or adhesive bonding. Taking sutures as an example, one end of the webbing passes through the connecting through-hole 328 and overlaps with the other end, and then both ends of the webbing are sutured to the covering assembly 200. Furthermore, if the webbing and the covering assembly 200 are detachably connected, the method of connection between them includes, but is not limited to, fastening the webbing to the covering assembly 200 or using other connection structures (e.g., a pair of snap buttons or a pair of adhesive buttons). Naturally, 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, thereby achieving connection between the engaging member 320 and the covering assembly 200.
[0068] Referring to Figures 9 and 10, in one embodiment, the shape of the connecting through-hole 328 is not limited and may be, for example, a circular hole or an elongated hole. The installation position of the connecting through-hole 328 on the engaging member 320 is also not specifically limited; for example, the connecting through-hole 328 may be located at the lower end of the engaging member 320 and close to the mounting opening 3263. If the connecting through-hole 328 is an elongated hole, its extending direction intersects the direction in which the position-restricting locking projection 315 slides within the mounting groove 326. Referring to Figures 9 to 11, in one embodiment, the position-restricting locking projection 315 includes a first projection 3151 and a second projection 3152, the second projection 3152 protruding outward from the outer circumference of the first projection 3151 to form a position-restricting edge 3153, the first projection 3151 is connected to the fixed seat 310, and the second projection 3152 is provided at a distance from the fixed seat 310 to form a position-restricting recess 3154. In one embodiment, the mounting groove 326 includes a first groove body 3261 and a second groove body 3262 provided on the outer circumference of the first groove body 3261 and communicating with the first groove body 3261, both of which 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 are positioned opposite each other and spaced apart in a direction perpendicular to the sliding direction of the position-restricting locking projection 315, with the first wall 3265 located on one side of the second wall 3265 that is close to the fixing seat 310. The third wall 3267 extends in a direction perpendicular to the sliding direction of the position-restricting locking projection 315 and connects 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-restricting locking projection 315. The first wall 3265, the second wall 3266, and the third wall 3267 all define the second groove 3262. In this way, when the mounting groove 326 engages with the position-restricting locking projection 315, the position-restricting edge 3153 is restricted to the position within the second groove body 3262, and the side wall (first wall body 3265) of the second groove body 3262 is restricted to the position within the position-restricting recess 3154.In this way, the position-restricting locking projection 315 can be detached from the mounting groove 326 only through the mounting opening 3263, thereby preventing the engaging member 320 from separating from the fixed seat 310 after the engaging member 320 is connected to the fixed seat 310 along the protruding direction of the position-restricting locking projection 315.
[0069] The connection between the first protrusion 3151 and the second protrusion 3152 may be fixed, for example, they may be integrally molded and welded or bonded together. Naturally, the connection between the first protrusion 3151 and the second protrusion 3152 may be detachable, for example, locked. Similarly, the connection relationship between the first protrusion 3151 and the fixed seat 310 can be referred to from the connection relationship between the first protrusion 3151 and the second protrusion 3152, so it is not specifically limited here.
[0070] In this embodiment, the mounting opening 3263 is provided facing downward along the length of the handle tube 132 or the handle member 110. Naturally, 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 ensured. For example, it may be provided facing forward or backward along the movement of the carrier.
[0071] Specifically, in this embodiment, the first protrusion 3151 and the second protrusion 3152 both have a circular structure, and thus the position-restricting edge 3153 and the position-restricting recess 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 mounting opening 3263 described above 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 communicates with the second groove segment 3264b of the first groove body 3261, the first groove segment 3264a of the second groove body 3262 communicates with the second groove segment 3264b of the second groove body 3262, the first groove segment 3264a of the first groove body 3261 communicates with the first groove segment 3264a of the second groove body 3262, the second groove segment 3264b of the first groove body 3261 communicates with the second groove segment 3264b of the second groove body 3262, and both the first groove segment 3264a of the first groove body 3261 and the first groove segment 3264a of the second groove body 3262 form a mounting opening 3263 with a T-shaped cross-section. In this way, when the engaging member 320 engages with the position-restricting locking projection 315 on the fixed seat 310 via the mounting groove 326, the position-restricting edge 3153 is restricted to the position within the second groove segment 3264b of the second groove body 3262, and the first projection 3151 is located 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 all 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-restricting locking projection 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-restricting locking projection 315. The elongated wall portions of the first wall 3265, the second wall 3266, and the third wall 3267 all define the first groove segment 3264a of the second groove 3262. The arc-shaped wall portions of the first wall 3265, the second wall 3266, and the third wall 3267 all define the second groove segment 3264b of the second groove 3262.
[0073] As an engaging member 320, the position-limiting locking projection 315 rotates within the second groove segment 3264b and the second groove 3262 of the first groove 3261, thereby allowing the engaging member 320 to rotate relative to the fixed seat 310. In other words, once the engaging member 320 is connected to the fixed seat 310, it 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 projection 3152. Once the first covering portion 230 is connected to the frame 100, the first covering portion 230 can be adjusted by rotating the engaging member 320, thereby preventing twisting of the first covering portion 230. As can be seen from this, the rotatability of the engaging member 320 relative to the fixed seat 310 improves the flexibility of the fixed connection of the first covering portion 230. When adjusting the tilt angle at the backrest, the backrest may move along with the cover assembly 200, and the portion of the cover assembly 200 connected to the engaging member 320 may rotate to some extent. In this case, the engaging member 320 can rotate relative to the fixed seat 310, thereby reducing the twisting and wrinkling of the cover assembly 200 at the engaging member 320.
[0074] In this embodiment, the first protrusion 3151 and the second protrusion 3152 are provided coaxially, that is, their central axes are collinear. Furthermore, the mounting hole 316 penetrates the first protrusion 3151, the second protrusion 3152, and the fixing seat 310 in order, and the axis of the mounting hole 316 is located at the central axis of the first protrusion 3151 and the second protrusion 3152. The radius of the circle formed by the arc of the second groove segment 3264b of the second groove body 3262 is greater than or equal to the radius of the second protrusion 3152, and the radius of the circle formed by the arc of the second groove segment 3264b of the first groove body 3261 is greater than or equal to the radius of the first protrusion 3151. In this way, the second protrusion 3152 can easily enter the second groove segment 3264b of the second groove body 3262, and the first protrusion 3151 can easily enter the second groove segment 3264b of the first groove body 3261.
[0075] Referring to Figure 10, in one embodiment, the engaging member 320 is provided with a position limiting structure 327, and when the engaging member 320 is operated and the mounting groove 326 engages with the position limiting locking projection 315, the position limiting locking projection 315 moves from the mounting opening 3263 into the interior of the mounting groove 326 against the position limiting structure 327. Specifically, the position limiting structure 327 includes a position limiting portion 3271 and a perforated portion 3272. The position limiting portion 3271 is provided on one side or both opposing 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 may 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. Perforated portions 3272 are provided on one side or both opposing side walls of the first groove body 3261 at positions corresponding to the position limiting portions 3271. More specifically, the perforated portions 3272 are provided on the surface of the first wall body 3265 facing the fixed seat 310 and penetrate the first wall body 3265 in a direction perpendicular to the sliding direction of the position limiting locking projection 315. When the position limiting portion 3271 is pressed against the position limiting locking projection 315, the position limiting portion 3271 moves toward the perforated portion 3272, thereby elastically deforming the position limiting portion 3271 and reducing the size of the perforated portion 3272.
[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, and more specifically, on two opposing surfaces of the first wall body 3265 facing the first groove body 3261. Along the width direction of the mounting opening 3263, one perforated portion 3272 is provided on each side of the mounting opening 3263. When it is necessary to connect the engaging member 320 to the fixed seat 310, after aligning the mounting opening 3263 of the engaging member 320 with the position limiting locking projection 315, the engaging member 320 can be further operated (for example, pushed or pulled) in a diagonally downward direction, and in this way the engaging member 320 can move relative to the fixed seat 310, that is, the position limiting locking projection 315 can be considered to move from the mounting opening 3263 to the inside of the mounting groove 326 relative to the engaging member 320. As the position-restricting locking projection 315 enters the mounting groove 326, the second projection 3152 is first inserted into the first groove segment 3264a of the second groove body 3262, and at the same time, the first projection 3151 is inserted into the first groove segment 3264a of the first groove body 3261. When the first projection 3151 comes into contact with the two position-restricting portions 3271, the position-restricting portions 3271 gradually move toward the perforated portion 3272, the position-restricting portions 3271 undergo elastic deformation, and the perforated portion 3272 provides the space necessary for the movement of the position-restricting portions 3271. When the first protrusion 3151 moves beyond the first groove segment 3264a and into the second groove segment 3264b, the two position limiting portions 3271 return to their original positions to restrict 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 or only a small external force, the engaging member 320 and the fixed seat 310 remain relatively fixed, preventing the position limiting locking protrusion 315 from easily exiting the mounting groove 326 through the mounting opening 3263. If 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., approximately diagonally upward), thereby causing the position limiting locking protrusion 315 to exit from the mounting opening 3263 of the mounting groove 326 during the process of the engaging member 320 moving relative to the fixed seat 310.During this process, the first protrusion 3151 again comes into contact with the position limiting portion 3271, causing the position limiting portion 3271 to gradually move toward the openwork portion 3272, and thus deform to some extent. After the first protrusion 3151 has moved beyond the position limiting portion 3271, the openwork portion 3272 and the position limiting portion 3271 return to their original shape and position.
[0077] Continuing to refer to Figure 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-restricting projection 315 via 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-restricting projection 315 (i.e., the end face of the second projection 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-restricting projection 315 not sufficiently overlapping 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 engaging with the position-restricting projection 315.
[0078] In one embodiment, the above-described covering connection structure 300 is provided between the two first covering portions 230 and the corresponding handle members 110 and / or pusher levers 132. Specifically, in this embodiment, as shown in Figure 8, the covering connection structure 300 is provided between the two first covering portions 230 and the corresponding handle members 110 and pusher levers 132. In this way, the reliability of the connection between the first covering portions 230 and the frame 100 can be improved, which is advantageous in that the first covering portions 230 become flatter after being connected to the frame 100, thereby improving the aesthetic appearance of the carrier.
[0079] Figure 12 shows a perspective view of the carrier provided in the third embodiment of the present invention, with the sheathing assembly 200 omitted. This carrier includes a frame 100, a sheathing assembly 200 (see the relevant drawings of the first embodiment), and a sheathing connection structure 300. The carrier in this embodiment is a variation of the carrier in the second embodiment. Where there is no inconsistency, the structure of the members and the connection relationships between members in this embodiment should be described in the description of the second embodiment. The differences between this embodiment and the second embodiment will be described below.
[0080] Referring to Figures 13 to 15, in this embodiment, both the first protrusion 3151 and the second protrusion 3152 have an elongated structure. Both the first protrusion 3151 and the second protrusion 3152 extend along the length direction of the handle member 110 and / or pusher lever 132. Along the direction of extension of the first protrusion 3151 and the second protrusion 3152, the tips of the first protrusion 3151 and the second protrusion 3152 are arc-shaped. The second groove segment 3264b of the second groove body 3262 has a contact edge portion 3131a that is provided facing the mounting opening 3263. When the mounting groove 326 engages with the position-restricting locking projection 315, the tip of the second projection 3152 abuts against the contact edge 3131a, and the position-restricting edge 3153 is restricted to the position within the first groove segment 3264a and the second groove segment 3264b of the second groove body 3262. Specifically, in this embodiment, the contact edge 3131a is arc-shaped, and its arc angle matches the arc angle of the outer edge of the tip of the second projection 3152. Since the tips of the first projection 3151 and the second projection 3152 are arc-shaped, it is advantageous for the position-restricting locking projection 315 to be quickly and accurately introduced into the mounting groove 326 from the mounting opening 3263, thereby improving the speed of connection between the engaging member 320 and the fixed seat 310. Furthermore, the tip of the first protrusion 3151 is arc-shaped, and when it abuts against the position limiting portion 3271, it is advantageous in improving the smoothness of the position limiting portion 3271 moving toward the perforated portion 3272. In other embodiments, the second groove segment 3264b may have a different shape; for example, both the second groove segment 3264b and the first groove segment 3264a have a similar elongated structure, and the specifics are not limited here. In order to ensure the stability of the position limiting locking protrusion 315 being engaged in the mounting groove 326 and to prevent the engaging member 320 from easily detaching from the fixed seat 310, in this embodiment, as shown in Figure 13, the first protrusion 3151 is provided with an inwardly recessed opening 31511. When the mounting groove 326 engages with the position-restricting locking projection 315, the recess 31511 is used to engage and fit with the position-restricting portion 3271 in the position-restricting structure 327.
[0081] As the position-restricting locking projection 315 enters the mounting groove 326, the second projection 3152 is first inserted into the first groove segment 3264a of the second groove body 3262, and at the same time, the first projection 3151 is inserted into the first groove segment 3264a of the first groove body 3261. When the first projection 3151 comes into contact with the two position-restricting portions 3271, the position-restricting portion 3271 gradually moves toward the perforated portion 3272, and the position-restricting portion 3271 undergoes elastic deformation, with the perforated portion 3272 providing the space necessary for the movement of the position-restricting portion 3271. When the engaging member 320 moves to a predetermined position, that is, when the contact edge 3131a of the second groove 3262 of the engaging member 320 contacts the tip of the second protrusion 3152, the position limiting portion 3271 on the side wall of the first groove 3261 engages and fits perfectly into the recess 31511 of the first protrusion 3151. At this time, both the position limiting portion 3271 and the perforated portion 3272 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, preventing the position limiting locking protrusion 315 from easily retracting from the mounting groove 326 via the mounting opening 3263. Similarly, during 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 in a direction toward the openwork portion 3272, causing the position limiting portion 3271 to exit from the recess 31511. Once 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 shape and position.
[0082] Referring to Figures 13 and 14, in order to improve the stability and reliability of the connection between the engaging member 320 and the covering assembly 200, in this embodiment, the connecting through-hole 328 is an elongated hole, and the direction of extension of the connecting through-hole 328 is substantially parallel to the direction in which the position-limiting locking projection 315 slides relative to the mounting groove 326. In order to avoid interference when the engaging member 320 is connected to the covering assembly 200 via the connecting through-hole 328, in this embodiment, the connecting through-hole 328 can be considered to be located on the side of the engaging member 320, parallel to the first groove segment 3264a, and located outside the first groove segment 3264a. Of course, in other embodiments, the connecting through-hole 328 may have a different shape. For the position of the connecting through-hole 328, please refer to the positioning of the connecting through-hole 328 in the second embodiment.
[0083] Specifically, in this embodiment, as shown in Figures 12 and 13, the fixing seat 310 is provided with two mounting holes 316 along its length, which is advantageous in improving the stability of the fixing seat 310 being attached to the frame 100. More specifically, compared to the first embodiment, a recessed portion 111 is similarly provided in the frame 100 where it connects to the fixing seat 310, and the two mounting holes 316 are for fastening members to pass through and attach the fixing seat 310 to the recessed portion 111 of the frame 100. Of course, in other embodiments, the recessed portion 111 in the frame 100 may be omitted.
[0084] In this embodiment, the above-described covering connection structure 300 is provided between the two first covering portions 230 and the corresponding handle member 110 and pusher lever 132.
[0085] Figure 16 shows a perspective view of the carrier provided in the fourth embodiment of the present invention, with the sheathing assembly 200 omitted. This carrier may include a frame 100, a sheathing assembly 200 (see the relevant drawings of the first embodiment), and a sheathing connection structure 300. The carrier in this embodiment can be considered a variation of the carriers in the second and third embodiments described above. Where there is no inconsistency, refer to the descriptions in the second and third embodiments for the structure of the members and the connection relationships between the members in this embodiment. The differences between this embodiment and the second and third embodiments described above will be explained below.
[0086] In this embodiment, the connection structure 300 for the covering included in the carrier includes two types of structures.
