[0002] The motorcycle tail rack is a component installed behind the rear seat of a motorcycle. It provides a support surface for placing items on the rear seat and also protects the passenger. It is an important component of the motorcycle.
[0003] Existing motorcycle rear racks are designed to match the width of the motorcycle's rear end, resulting in a small overall size. When the motorcycle needs to transport larger items using the rack, the small support surface at the rear makes the items less stable, and the goods are prone to falling off when encountering bumpy roads. Utility Model Content
[0004] The purpose of this invention is to provide an expandable motorcycle tail rack to at least partially solve the aforementioned technical problems.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a shelf, wherein both sides of the shelf are provided with extension support plates, the back of the shelf is provided with a telescopic component for pushing the two extension support plates to extend outward or retract inward, and the rear end of the shelf is provided with two fixing components for constraining and fixing the telescopic component; The fixing assembly includes a pull frame that is vertically inserted into the rear end of the shelf and extends inward therein, a first connecting rod and a second connecting rod that are inserted into the inner side of the shelf and slide inward and extend outward at one end and are fixedly connected to both ends of the extension support plate, a push rod that is fixedly installed on the inner end of the pull frame, and an inclined rod that is slidably installed at both ends of the push rod and fixedly connected to one end of the two first connecting rods and the second connecting rod, respectively.
[0006] Preferably, the fixing component includes two positioning plates fixedly disposed at the rear end of the shelf and located outside the pull frame, and a first screw that passes through the positioning plates and is threaded at one end to the edge of the pull frame.
[0007] Preferably, the pull frame has multiple fixing holes longitudinally opened on both sides, one of which is located at the outer end of the pull frame. When the two extension support plates are in contact with the edge of the shelf, the first screw is threaded into the fixing hole at the outer end. When the extension support plate is extended to its maximum, the first screw is threaded into the fixing hole at the innermost end.
[0008] Preferably, guide grooves are provided on the sides of the two inclined rods, and guide blocks matching the guide grooves are fixedly provided at both ends of the push rod. The guide blocks are inserted into the guide grooves and slide, and the guide blocks are T-shaped guide blocks.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-7 This utility model provides a technical solution: an expandable motorcycle tail rack, including a rack 1, with extension support plates 2 on both sides of the rack 1, and a telescopic component 3 on the back of the rack 1 for pushing the two extension support plates 2 to extend outward or retract inward, and two fixing components 5 at the tail end of the rack 1 for constraining and fixing the telescopic component 3. The fixing component 5 includes a pull frame 31 that is vertically inserted into the rear end of the shelf 1 and extends into it, a first connecting rod 32 and a second connecting rod 33 that are inserted into the inside of the shelf 1 and extend outward at one end and are fixedly connected to both ends of the extension support plate 2, a push rod 34 that is fixedly installed on the inner end of the pull frame 31, and an inclined rod 35 that is slidably installed at both ends of the push rod 34 and is fixedly connected to one end of the two first connecting rods 32 and the second connecting rod 33, respectively. Pulling outwards from the pull frame 31 causes the push rod 34 connected to the inner end of the pull frame 31 to move towards the area where the distance between the two inclined rods 35 is small. The guide blocks 341 set at both ends of the push rod 34 slide within the guide grooves 351 opened on the inclined rods 35, allowing the push rod 34 to slide between the two inclined rods 35. The first connecting rod 32 and the second connecting rod 33 connected to both ends of the inclined rods 35 constrain the inclined rods 35. When pulled outwards, the two inclined rods 35 move outwards respectively, and the extension support plates 2 connected to the two first connecting rods 32 and the second connecting rod 33 move outwards from the edge of the shelf 1. When the outermost fixing hole 311 of the pull frame 31 is aligned with the first screw 52, the pull frame 31 is constrained and fixed by the first screw 52. The top of the extension support plate 2 is flush with the highest part of the top of the shelf 1, which can expand the overall support area of the shelf 1 for supporting large and heavy items, making the transport of fixed items on the shelf 1 safer and more reliable.
[0019] More preferably, the fixing component 5 includes two positioning plates 51 fixedly disposed at the rear end of the shelf 1 and located outside the pull frame 31, and a first screw 52 that passes through the positioning plates 51 and is threaded at one end to the edge of the pull frame 31; The positioning plate 51 at the end of the shelf 1 is used to support the first screw 52. The first screw 52 passes through the positioning plate 51 and is threaded to both sides of the pull frame 31, thereby constraining and fixing the adjusted extension support plate 2.
[0020] More preferably, the pull frame 31 has multiple fixing holes 311 longitudinally opened on both sides. One of the fixing holes 311 is located at the outer end of the pull frame 31. When the two extended support plates 2 are in contact with the edge of the shelf 1, the first screw 52 is threaded into the fixing hole 311 at the outer end. When the extended support plate 2 is extended to the maximum, the first screw 52 is threaded into the fixing hole 311 at the innermost end. The extension support plate 2 can be adjusted by fixing it in different fixing holes 311 through the multiple fixing holes 311 provided on the pull frame 31, making it more practical and flexible. When the extension support plate 2 moves to contact the edge of the shelf 1, the first screw 52 is opposite to the fixing hole 311 located at the rearmost part of the inner side of the pull frame 31, which constrains and fixes the retracted extension support plate 2. The pull frame 31 can be moved to the rear end of the shelf 1. When it is not necessary to transport large items, the whole thing can be retracted for convenient use.
[0021] More preferably, guide grooves 351 are respectively provided on the sides of the two inclined rods 35, and guide blocks 341 matching the guide grooves 351 are fixedly provided at both ends of the push rod 34. The guide blocks 341 slide in the guide grooves 351, and the guide blocks 341 are T-shaped guide blocks 341. The guide groove 351 on the side of the inclined rod 35 matches the guide blocks 341 at both ends of the push rod 34. The guide blocks 341 are inserted into the guide groove 351 and move, so that the two ends of the push rod 34 slide against the side of the inclined rod 35, which can cause the two inclined rods 35 to expand outward or move closer together.
[0022] More preferably, the inner end of the pull frame 31 is inserted into the push rod 34 and fixed by the second screw 6, the two ends of the tilt rod 35 are respectively inserted into one end of the first connecting rod 32 and the second connecting rod 33 and fixed by the second screw 6, and the other ends of the first connecting rod 32 and the second connecting rod 33 are respectively fixedly connected to the extension support plate 2 by the second screw 6. The push rod 34 is fixed to the pull frame 31 and the push rod 34 by the second screw 6. The two ends of the tilt rod 35 are fixed to the first connecting rod 32 and the second connecting rod 33 by the second screw 6 respectively. The other ends of the first connecting rod 32 and the second connecting rod 33 are also fixed by the second screw 6. This allows the push rod 34 to be detached from the pull frame 31, the tilt rod 35 to be detached from the first connecting rod 32 and the second connecting rod 33, and the first connecting rod 32 and the second connecting rod 33 to be detached from the extension support plate 2. This facilitates the installation of the overall retractable structure on the shelf 1 and also facilitates subsequent maintenance.
[0023] More preferably, two positioning sleeves 4 are fixedly installed on the back of the shelf 1, and the inner end of the pull frame 31 is inserted and slidably inserted into the two positioning sleeves 4 respectively; The positioning sleeve 4 is provided on the back of the shelf 1, and the inner end of the pull frame 31 passes through the positioning sleeve 4, which can constrain the other end of the pull frame 31, prevent the pull frame 31 from tilting up, and enable the overall telescopic assembly 3 to be used normally.
[0024] More preferably, both sides of the shelf 1 are provided with openings for the passage of the first connecting rod 32 and the second connecting rod 33; The openings on both sides of the shelf 1 allow the first connecting rod 32 and the second connecting rod 33 to pass through the shelf 1 outwards, and constrain and limit the first connecting rod 32 and the second connecting rod 33.
[0025] One specific application of this embodiment is as follows: When no support for the items is needed, the pull frame 31 is pushed inward, and the push rod 34 moves towards the wider part of the two inclined rods 35. When the push rod 34 moves, the two inclined rods 35 move together. When the two outward extended support plates 2 contact the edge of the shelf 1, the last fixing hole 311 at the inner end of the pull frame 31 is aligned with one end of the first screw 52, and the pull frame 31 is constrained and fixed by the first screw 52. At the same time, the outer end of the pull frame 31 moves closer to the end of the shelf 1. When no goods need to be transported, the expansion is reduced and does not affect the normal use of the shelf 1.
