[0049] The carrier device provided in this embodiment is used for loading, facilitating the collection and transportation of bicycles. It includes a carrier board 100 and a base frame 200. A plurality of bearing parts 110 are provided on the carrier board 100. Each bearing part includes two groove parts that match the front and rear wheels of the bicycle. For the convenience of subsequent description, the two groove parts are respectively referred to as the first groove part 111 and the second groove part 112. The carrier board 100 is rotatably connected to the base frame 200 to switch between at least two positions: in the first position, the carrier board 100 is parallel to the horizontal plane and is supported by the base frame 200, as shown in Figure 1 and Figure 2 shown. In the second position, there is a preset angle between the carrier board 100 and the horizontal plane, as shown in Figure 3 and Figure 4 shown. It also includes a locking component and a limiting component. The limiting component is used to limit the relative position between the bicycle and the carrier board 100, and the locking component is used to limit the relative position between the carrier board 100 in the second position and the base frame 200.

[0050] After being set as above, in practical applications of this carrier device, when storing bicycles, the carrier board 100 can be in the first position. The bicycle is placed on the carrier board 100 with its front and rear wheels clamped in the two groove parts of a bearing part 110. In this way, the regular placement of bicycles can be achieved, which can be referred to Figure 5 for understanding. When it is necessary to centrally transport bicycles, the relative position between the bicycle and the carrier board 100 can be restricted by the limiting component, and then the carrier board 100 loaded with bicycles can be rotated relative to the base frame 200 to the second position, which can be referred to Figure 6 for understanding. Then, the relative position between the carrier board 100 and the base frame 200 is locked by the locking component. In this way, the carrier board 100 and the bicycles loaded on it are relatively fixed as a whole and can be placed in the compartment of a van as a whole. Since the carrier board 100 forms a preset angle with the horizontal plane, in this way, it will not occupy too much space, and multiple such carrier devices loaded with bicycles can be placed in sequence in the compartment of the van, and the bicycles will not squeeze each other, avoiding damage to the bicycles caused by squeezing during transportation.

[0051] In this embodiment, the base frame 200 includes a bottom frame part 210 and at least one side frame part 220 fixedly provided on one side of the bottom frame part 210. In the illustrated solution, to ensure stability and reliability, side frame parts 220 are fixedly provided on both sides of the bottom frame part 210.

[0052] The carrier board 100 is specifically rotatably connected to the bottom frame part 210, and the two can be rotatably connected through a rotating shaft 300. At least one limiting part 222 is provided on the side frame part 220 to limit the angle between the carrier board 100 and the horizontal plane when it rotates to the second position.

[0053] In the first position, the chassis part 210 is used to support the car carrier plate 100. It can be understood that during normal use, the chassis part 210 is placed on the ground and supported by the ground. At this time, the car carrier plate 100 is parallel to the horizontal plane. In the second position, after the car carrier plate 100 rotates around the rotating shaft 300 to the second position, it abuts against the limiting part 222. It can be combined with Figure 9 Understand, Figure 9 Is Figure 3 The partial enlarged view of part C in

[0054] In practical applications, in order to make the overall size of the car carrier device relatively small after the car carrier plate 100 rotates to the second position, so as to facilitate placing more car carrier devices in the limited space of the freight car body, that is, transporting more bicycles, the car carrier plate 100 can be set in a square or rectangular shape. One side of it is rotatably connected to the chassis part 210 through the rotating shaft 300. In the axial direction of the rotating shaft 300, the size of the chassis part 210 is equivalent to that of the car carrier plate 100. The car carrier plate 100 is located between the two side frame parts 220. The setting of the side frame parts 220 does not affect the normal rotation of the car carrier plate 100; in the direction perpendicular to the rotating shaft 300, the size of the chassis part 210 is not greater than half of the size of the car carrier plate 100, and the size of the side frame parts 220 is adapted to that of the chassis part 210. Refer to Figure 3 And Figure 6 Understand, in this way, when the car carrier plate 100 is in the second position, that is, in the position convenient for loading and transporting, the overall width dimension (in the direction perpendicular to the rotating shaft 300) of the car carrier device is small, which is convenient for placing more car carrier devices in the limited space.

[0055] In actual setting, when the car carrier plate 100 is in the second position, the angle between it and the horizontal plane can be set according to requirements, such as meeting the requirements of small overall occupied space and reliable positioning of the bicycle on the car carrier plate 100. For example, this angle can be 60 degrees, 65 degrees or 70 degrees, or it can be selected between 60 and 70 degrees.

[0056] In actual setting, the car carrier plate 100 can also be in the third position or more positions. In these positions, the car carrier plate 100 also forms a preset angle with the horizontal plane, but each preset angle is different. In this way, when the car carrier plate 100 is in the transportable state, there are multiple choices, and the inclination degree between the car carrier plate 100 and the horizontal plane when it is in the transport state can be selected according to the actual state of the bicycles carried on it. At this time, a limiting part structure can still be set on the side frame part 220 to facilitate positioning the car carrier plate 100 and then locking the relative positions of the car carrier plate 100 and the base frame 200 by using the locking component. It can be understood that the setting of the limiting part structure should not affect the switching of the car carrier plate 100 between each position.

[0057] When the loading board 100 is in the second position, the locking component specifically locks the relative position of the loading board 100 and the side frame part 220. On the basis of providing two side frame parts 220, two groups of locking components are specifically provided, which are respectively used for locking the two side frame parts 220 and the loading board 100, so as to improve the stability of the overall structure of the loading device in the second position and ensure transportation safety.

[0058] Please also refer to Figures 7 to 10 , Figure 7 For Figure 1 the partial enlarged view of part A in Figure 8 For Figure 2 the partial enlarged view of part B in Figure 9 For Figure 3 the partial enlarged view of part C in Figure 10 It is the perspective schematic diagram of the locking component in the specific embodiment.

[0059] In this embodiment, the locking component includes a locking rod 410 and an elastic member 420. The elastic member 420 is arranged between the locking rod 410 and the loading board 100. The side frame part 220 has a first through hole 221. The locking rod 410 is connected to the loading board 100 and can move relative to the loading board 100. A snap ring 140 for clamping the locking rod 410 is arranged on the loading board 100, and it is configured as:

[0060] When the loading board 100 is in the second position and the elastic member 420 is in the normal state, the locking rod 410 is inserted into the first through hole 221 to lock the relative position of the loading board 100 and the side frame part 220, that is, the base frame 200, as Figure 9 shown; in the state where the locking rod 410 is clamped with the snap ring 140, the locking rod 410 disengages from the first through hole 221, and the elastic member 420 stores the elastic force for pulling the locking rod 410 to move in the direction of the first through hole 221. Here, the elastic member 420 being in the normal state means that the elastic member 420 is in a free state without external force.

[0061] Pull the locking rod 410 to make it disengage from the first through hole 221. The locking rod 410 moves towards the snap ring 140 and can be clamped with the snap ring 140. At this time, the locking between the loading board 100 and the side frame part 220 is released, and the two are relatively independent. The loading board 100 can rotate back to the first position from the second position. Obviously, when the loading board 100 rotates from the first position to the second position, the locking rod 410 and the snap ring 140 are in a clamped state. When the loading board 100 rotates to abut against the limiting part 222, the locking between the snap ring 140 and the locking rod 410 can be manually released. At this time, under the elastic force of the elastic member 420, the locking rod 410 moves in the direction of the first through hole 221 and is inserted into the first through hole 221, realizing the position locking of the loading board 100 and the base frame 200.

[0062] Furthermore, the locking component is also used to limit the relative position of the vehicle loading plate 100 and the base frame 200 in the first position.

[0063] Specifically, the bottom frame portion 210 has a second through hole 211 and is configured such that: when the elastic member 420 is in the first position and the elastic member 420 is in the normal state, the locking rod 410 is inserted into the second through hole 211 to lock the relative position of the vehicle loading plate 100 and the bottom frame portion 210, i.e., the base frame 200, as shown in FIG. Figure 7 When the locking rod 410 and the snap ring 140 are fixed, the locking rod 410 is disengaged from the second through hole 211, and the elastic member 420 reserves an elastic force to pull the locking rod 410 toward the direction of the second through hole 211.

[0064] It can be understood that the locking rod 410 can be inserted into the second through hole 211 when the loading plate 100 is in the first position, and can be inserted into the first through hole 221 when the loading plate 100 is in the second position. Obviously, the first through hole 221 and the second through hole 211 are located on a circle with the rotation center of the loading plate 100 as the center.

[0065] When in use, the vehicle loading plate 100 is in the first position, and a bicycle can be placed normally for people to take. The elastic member 420 is in a normal state, and the locking rod 410 is inserted into the second through hole 211 to limit the relative position of the vehicle loading plate 100 and the base frame 200. When the vehicle loading device is required to be transferred by a van, the locking rod 410 is manually pulled to disengage from the second through hole 211, move toward the clamping ring 140, and clamp with the clamping ring 140. The elastic member 420 is in an energy storage state. At this time, the vehicle loading plate 100 is in a free rotation state. When the vehicle loading plate 100 is rotated to abut against the limiting portion 222, since the locking rod 410 and the elastic member 420 are connected to the vehicle loading plate 100, the locking rod 410 and the elastic member 420 are connected to the vehicle loading plate 100. The locking rod 410 is manually released from the locking position of the snap ring 140, and the locking rod 410 moves toward the first through hole 221 under the elastic force of the elastic member 420 and is inserted into the first through hole 221, thereby locking the relative positions of the vehicle-carrying plate 100 and the base frame 200 in the second position, thereby facilitating the transportation of the vehicle-carrying device; when the vehicle-carrying device is transported to the designated position and the vehicle-carrying plate 100 needs to be rotated to the first position again, the locking rod 410 is manually pulled to disengage from the first through hole 221, move toward the snap ring 140, and lock it with the snap ring 140, so that the elastic member 420 is in an energy storage state, and the vehicle-carrying plate 100 is in a free rotation state and can be rotated from the second position to the first position.

[0066] Specifically, refer to Figures 7 to 10A mounting seat 430 is fixedly provided at the bottom of the vehicle loading plate 100, the locking rod 410 includes a rod body 411 and a protrusion 412 fixedly provided at one end of the rod body 411, the vehicle loading plate 100 has a first opening 120, the rod body 411 of the locking rod 410 passes through the mounting seat 430, and its protrusion 412 extends from the first opening 120 to protrude from the top surface of the vehicle loading plate 100, and the snap ring 140 is provided on the top surface of the vehicle loading plate 100, and the protrusion 412 is used to be fixedly matched with the snap ring 140, so that the operation is convenient for the operator.

[0067] The rod body 411 of the locking rod 410 is also fixed to the support portion 413. The elastic member 420 can be specifically a spring, which is sleeved on the rod body 411. Its two ends are respectively abutted against the mounting seat 430 and the support portion 413. The end of the rod body 411 relative to the protrusion 412 is used for insertion and cooperation with the first through hole 221 or the second through hole 211.

[0068] As shown in the diagram, the movement direction of the rod body 411 of the locking rod 410 relative to the carrier plate 100 is parallel to the axial direction of the rotating shaft 300, which is convenient for the operation of related structural parts. It can be understood that the first opening 120 has a certain length in the movement direction of the locking rod 410, so that the protrusion 412 can switch between the position where it is fixed with the retaining ring 140 and the position where the rod body 411 is inserted into the first through hole 221 or the second through hole 211.

[0069] It should be pointed out that, according to actual needs, the periphery of the plate body of the vehicle loading plate 100 can extend downward to form a peripheral wall portion to form a setting space for related components at the bottom of the vehicle loading plate 100, such as the groove portion of the aforementioned load-bearing portion 110, etc. At this time, it is obvious that the locking rod 410 should also pass through the peripheral wall portion at the corresponding position to cooperate with the first through hole 221 or the second through hole 211.

[0070] Specifically, the protruding portion 412 of the locking rod 410 and the rod body 411 can be relatively independent components, the supporting portion 413 can be integrally formed with the rod body 411, and the mounting seat 430 includes two opposite seat bodies 431 fixedly arranged on the peripheral wall of the vehicle loading plate 100 and a mounting plate 432 detachably fixedly connected to the two seat bodies 431, so as to facilitate the assembly of the locking rod 410 and the mounting seat 430. Figure 8 and Figure 10 During assembly, the rod body 411 of the locking rod 410 passes through the peripheral wall portion of the vehicle loading plate 100 located between the two seat bodies 431. After the elastic member 420 is sleeved on the inner end thereof close to the center of the vehicle loading plate 100, the mounting plate 432 is passed through the rod body 411 and fixed to the two seat bodies 431 by fasteners such as bolts. In this way, the elastic member 420 abuts between the support portion 413 and the mounting plate 432, and then the protrusion 412 is fixed to the inner end of the rod body 411 with fasteners such as screws, and the protrusion 412 is extended out of the first opening 120.

[0071] After such arrangement, only the protruding portion of the protrusion 412 and the snap ring 140 are on the top surface of the vehicle loading plate 100 , which is convenient for operation, and there will not be too many structures on the top surface of the vehicle loading plate 100 that affect the storage of the bicycle.

[0072] In actual configuration, the clamping ring 140 and the vehicle carrier plate 100 can be configured to be rotationally matched, and the clamping ring 140 can be rotated toward the protruding portion 412 to facilitate the clamping therebetween.

[0073] In this embodiment, the multiple load-bearing parts 110 on the vehicle loading plate 100 are arranged along a first direction. In the illustrated scheme, the first direction is parallel to the axis of the rotating shaft 300. In other examples, the arrangement direction may be other according to different requirements. Specifically, the maximum number of bicycles that can be stored on the vehicle loading plate 100 and the reliable fixation during subsequent transportation may be used as the setting criteria.

[0074] Along the first direction, the two groove portions corresponding to the positions of two adjacent bearing portions 110 are staggered in a direction perpendicular to the first direction, that is, the positions of the first groove portions 111 of each bearing portion 110 correspond, and the positions of the second groove portions 112 correspond, and the distance between the first groove portion 111 and the second groove portion 112 of each bearing portion 110 is adapted to the front and rear wheels of the bicycle.

[0075] Two adjacent first groove portions 111 are staggered in a direction perpendicular to the first direction, so that the distance between two adjacent carrying portions 110 can be reduced while avoiding interference between two adjacently stored bicycles, so that more bicycles can be placed on the same-sized loading plate 100.

[0076] In practical applications, such as Figure 5 and Figure 6 As shown, two adjacent bicycles are arranged facing each other on the bicycle loading plate 100 , that is, the front of one bicycle corresponds to the rear of the adjacent bicycle. This arrangement can also appropriately reduce the distance between two adjacent carrying parts 110 .

[0077] In actual configuration, one or more rollers 700 are further provided at the bottom of the vehicle loading plate 100 to facilitate pushing the vehicle loading plate 100 . Specifically, a roller 700 is provided at each of the four corners of the vehicle loading plate 100 .

[0078] In a specific solution, at least one lifting part for lifting can be provided on the vehicle loading plate 100, so that when loading and transporting, or other occasions requiring lifting, the vehicle loading device can be lifted using the lifting equipment of the van itself or other lifting equipment, so as to improve loading and unloading efficiency and save manpower.

[0079] In this embodiment, when the vehicle loading plate 100 is in the second position for loading and transportation, since the vehicle loading plate 100 is inclined relative to the horizontal plane, the bicycle carried thereon is also in an inclined state. In order to prevent the bicycle from being separated from the vehicle loading plate 100 and causing extrusion deformation or causing a safety accident, a limiting component is provided to limit the relative position of the bicycle and the vehicle loading plate 100. Specifically, after each carrying portion 110 of the vehicle loading plate 100 carries a bicycle, the relative position of the bicycle and the vehicle loading plate 100 can be limited by the limiting component, and then the vehicle loading plate 100 carrying the bicycle is rotated to the second position for subsequent operations.

[0080] like Figures 1 to 6 In the example shown, the limiting component specifically includes at least one limiting rod 500, which is detachably fixed to the vehicle loading plate 100. When the limiting rod 500 is fixed to the vehicle loading plate 100, the limiting rod 500 is located above a plurality of groove portions corresponding to the positions of the plurality of load-bearing portions 110. Taking the example in the figure as an example, the limiting rod 500 is located above each first groove portion 111, so that the limiting rod 500 can pass through the wheel of the bicycle embedded in the first groove portion 111 at each corresponding position.

[0081] like Figure 6 As shown, after the bicycles are loaded on the vehicle loading plate 100, the limiting rod 500 is passed through the wheels of each bicycle embedded in the first groove portions 111 in turn, and the limiting rod 500 is fixedly connected to the vehicle loading plate 100. In this way, the relative position of each bicycle and the vehicle loading plate 100 is limited by the limiting rod 500, and the bicycle will not fall off the vehicle loading plate 100 during the rotation of the vehicle loading plate 100 and when it is in the second position.

[0082] In actual setting, only one limiting rod 500 is required to limit one wheel of the bicycle to achieve the limiting effect. Preferably, the limiting rod 500 limits the wheel that is relatively far away from the rotating shaft 300.

[0083] The limit components can also be other ways, please refer to Figures 11 to 14 , Figure 11 A bottom view of a vehicle carrying device in another specific embodiment provided by the present invention; Figure 12 for Figure 11 A partial schematic diagram of the limiting component of the vehicle carrying device shown in the limiting position; Figure 13 for Figure 11 A partial schematic diagram of the vehicle carrier device shown in which the limiting component is in a non-limiting position; Figure 14 for Figure 11 A partial cross-sectional schematic diagram of the limiting component of the mid-car device in the limiting position.

[0084] In this embodiment, the limiting component includes a limiting frame 600, which is installed on the bottom of the vehicle loading plate 100, corresponding to the area where the multiple groove parts corresponding to the positions of the multiple bearing parts 110 are located. The limiting frame 600 includes support rods 610 with the same number as the bearing parts 110. The multiple support rods 610 are arranged along the first direction, and each support rod 610 is fixed to a limiting rod part 611 extending along the first direction. The limiting frame 600 can slide along the first direction to enable each limiting rod part 610 to switch between a limiting position and a non-limiting position. In the limiting position, the limiting rod part 611 can pass through the groove wall of the groove part at the corresponding position to insert the wheel of the bicycle embedded in the groove part at the corresponding position, such as Figure 12 As shown, it is obvious that the limiting rod 611 must be able to pass through the groove wall of the groove part, and the groove wall corresponding to the groove part is provided with a through hole that matches with it. When it is in the non-limiting position, the limiting rod 611 is separated from the wheel of the bicycle in the groove part at the corresponding position, as shown in FIG. Figure 13 shown.

[0085] In addition, a locking component is also included to limit the relative position of the limiting frame 600 and the vehicle loading plate 100 in the limiting position, thereby improving the reliability of the limiting frame in limiting the position of a single vehicle on the vehicle loading plate 100.

[0086] like Figure 11 As shown, the limiting frame 600 specifically corresponds to the area where each first groove portion 111 is located. In fact, since a base frame 200 is provided, the base frame 200 corresponds to the position of the second groove portion 112. Due to space limitations, only one limiting frame 600 corresponding to the position of each first groove portion 111 is provided. By limiting a wheel of each bicycle, the position limitation with respect to the vehicle loading plate 100 can be achieved.

[0087] Specifically, the limiting frame 600 includes a rectangular main frame 630, which is slidably connected to the bottom of the vehicle loading plate 100, and each first groove portion 111 is located in the area defined by the main frame 630. The two ends of the support rod 610 are respectively fixed to two frame rods 631 of the main frame 630 that are parallel to the first direction. Each support rod 610 corresponds to a first groove portion 111. When the limiting frame 600 is pulled to move along the first direction, each support rod 610 moves synchronously, so that each limiting rod portion 611 switches between the aforementioned limiting position and non-limiting position.

[0088] Specifically, in order to facilitate the movement of the limiting frame 600, a handle portion 620 is further provided, and the vehicle loading plate 100 has a second opening 130. The handle portion 620 passes through the second opening 130 and protrudes from the top surface of the vehicle loading plate 100, so that the operator can conveniently pull the limiting frame 600 to move between the limiting position and the non-limiting position through the handle portion 620. Obviously, the size of the second opening 130 can be suitable for the handle portion 620 to move therein to drive the limiting frame 600 to switch between the limiting position and the non-limiting position.

[0089] In a specific solution, a plurality of U-shaped members 640 are provided along a first direction at each rack 631 corresponding to the main frame 630 at the bottom of the vehicle loading plate 100. During assembly, the rack 631 of the main frame 630 passes through the U-shaped member 640 at the corresponding position to limit the sliding direction of the rack 631.

[0090] Of course, other forms of guide slides may also be provided at the bottom of the vehicle loading plate 100 to cooperate with the rack rod 631 .

[0091] like Figure 14 As shown, in the specific scheme, the aforementioned locking component includes a fastener 650 and a fixing hole 660 provided on the limiting frame 600, the fixing hole 660 has an internal threaded portion, the fastener 650 has an external threaded portion matching the internal threaded portion, and a through hole corresponding to the position of the fixing hole 660 is provided on the vehicle loading plate 100. When the limiting frame 600 is in the limiting position, the through hole on the vehicle loading plate 100 corresponds to the position of the fixing hole 660 of the limiting frame 600. At this time, the fastener 650 can be used to pass through the through hole and the fixing hole 660 of the vehicle loading plate 100 in sequence, and the fastener 650 is threadedly connected to the fixing hole 660, thereby limiting the relative position of the limiting frame 600 and the vehicle loading plate 100.

[0092] When the limiting frame 600 needs to be switched from the limiting position to the non-limiting position, the fastener 650 is unscrewed to release the connection.

[0093] Specifically, another threaded hole may be provided on the vehicle loading plate 100 so that when the vehicle loading plate 100 and the limiting frame 600 are not locked, the fastener 650 may be screwed into the threaded hole to avoid loss. Figure 12 and Figure 13 It should be understood that when the fastener 650 is screwed into the threaded hole of the vehicle loading plate 100, it does not interfere with the limiting frame 600, nor does it affect the movement of the limiting frame 600 between the limiting position and the non-limiting position.

[0094] In this embodiment, each groove portion of the bearing portion 110 is separately provided from the vehicle carrier plate 100 to facilitate the processing of each groove portion. The vehicle carrier plate 100 is provided with mounting holes at positions corresponding to each groove portion. After the groove portion is embedded in the corresponding mounting hole, it is detachably connected to the vehicle carrier plate 100. In this way, it is convenient to separately replace a damaged groove portion, reducing costs.

[0095] There can be various structures for the groove portion. Two of them will be exemplarily introduced below.

[0096] As Figure 15 shown, Figure 15 is a schematic structural diagram of the groove portion in a specific embodiment.

[0097] Figure 15 In the shown solution, the groove portion is integrally formed by a sheet metal part, including two opposite groove side walls 1101 and a groove bottom wall 1102 connecting the two groove side walls 1101. It also includes a mounting plate portion 1103 extending outward along the opening peripheral wall of the groove portion. The groove portion is fixedly connected to the vehicle carrier plate 100 through this mounting plate portion 1103. For specific reference, please Figures 1 to 6 understand.

[0098] Among them, the groove side wall 1102 has a set elastic deformation amount. In this way, when the wheel of a single bicycle is snapped into the groove portion, the two groove side walls 1102 can expand outward to clamp the wheel of the single bicycle. After the single bicycle is taken out, the groove side wall 1102 can return to its original state. Obviously, the distance between the two groove side walls 1102 is less than the thickness of the wheel of the single bicycle.

[0099] In the illustrated solution, the groove bottom wall 1102 of the groove portion has an arc-shaped structure, and the groove side wall 1101 has a matching shape. It can be understood that in actual setting, it is not limited to this shape.

[0100] As Figure 16 shown, Figure 16 is a schematic structural diagram of the groove portion in another specific embodiment.

[0101] Figure 16 In the shown solution, the groove portion includes a frame body 1104 having a cavity and a bracket 1105 mounted on the frame body 1104. The bracket 1105 includes two opposite frame arms 1151. The two opposite side walls of the frame body 1104 have notches 1141 for mounting the bracket 1105. The two frame arms 1151 of the bracket 1105 are respectively located in the two notches 1141 at corresponding positions. Rotatable wheels 1152 are mounted on the frame arms 1151 of the bracket 1105. The frame arms 1151 of the bracket 1105 have a set elastic deformation amount.

[0102] After the above settings, when the wheels of the bicycle are inserted into the groove portion, they are located between the two wheels 1152 and squeeze the two wheels 1152, causing the two arm portions 1151 of the bracket 1105 to open outward to clamp the wheels of the bicycle. After the bicycle is removed, the arm portions 1151 can return to their original state. Obviously, the distance between the two wheels 1152 is less than the thickness of the bicycle wheel.

[0103] It can be understood that the rotation axis of the wheel 1152 is parallel to the length direction of the groove portion, or in other words, parallel to the length direction of the bicycle.

[0104] The groove portion can be fixedly connected to the carrier plate 100 through the frame body 1104, and reference can be made to Figure 12 and Figure 13 for understanding.

[0105] Figure 12 and Figure 13 In the scheme shown, the groove portion is Figure 16 of a structure, and the limiting member adopts the form of a limiting frame 600. At this time, on the groove wall of the groove portion, specifically in Figure 16 the groove portion structure, a through hole 1142 for the limiting rod portion 611 of the limiting frame 600 to pass through is provided on the side wall of the frame body 1104.

[0106] It can be understood that when the limiting member adopts the form of a limiting frame 600 and the groove portion adopts Figure 15 the structure shown, a through hole for the limiting rod portion 611 to pass through should be provided on the groove side wall 1101 in Figure 15 .

[0107] The above has introduced the carrier device provided by the present invention in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
