Description

Technical Field

[0001] The present invention relates to the field of luggage, and particularly to a bag with an externally attached helmet. Background Art

[0002] With the improvement of traffic safety regulations in various places, traffic participants riding shared electric vehicles are gradually required to wear helmets to ensure life safety.

[0003] Currently, generally a basket is configured at the front of a shared electric vehicle, and an ordinary helmet is placed in the basket. The ordinary helmet is connected to the body of the shared electric vehicle through a telescopic rope to prevent theft. However, since the ordinary helmet is connected to the vehicle body, in the event of a traffic accident, a rider often gets injured because they cannot quickly disengage from the shared electric vehicle, posing a certain safety hazard. In addition, since the shared electric vehicle stays on the roadside most of the day, the helmet placed in the basket is easily covered with dust and even gets wet on rainy days, soiling the helmet. Therefore, in actual use, riders generally do not want to wear such dirty helmets, and the shared bicycle operator needs to regularly recycle and clean them, which is time-consuming and laborious.

[0004] To solve the safety hazard caused by the connection between the helmet and the vehicle body, some people have proposed a solution of setting a Bluetooth lock on the basket. Usually, after placing the helmet in the basket, the Bluetooth lock is locked, and the rider unlocks the Bluetooth lock when using the bicycle. However, this solution cannot solve the problem that the helmet is easily soiled, and at the same time, using a Bluetooth lock also increases the cost of the shared bicycle operator. Some people have also proposed adding an object box to the electric vehicle and placing the helmet in the object box to solve the problems that the rider cannot quickly escape from the vehicle body after wearing the helmet and the helmet is easily soiled. However, for the shared bicycle operator, on the one hand, the cost increases; on the other hand, the weight of the whole vehicle becomes larger, resulting in a shorter battery life, and the maintenance and replacement of the battery will become more frequent, increasing the workload of daily maintenance.

[0005] Although there are also foldable helmets that can be folded in the prior art, such as a foldable helmet for a folding assisted bicycle with a patent number of CN201420783181.5, this foldable helmet can reduce its volume by folding and thus be put into a handbag or backpack. However, this foldable helmet needs to be placed inside the bag when carried, occupying the storage space inside the bag. For customers of shared bicycles, they need to prepare a foldable helmet and a bag that can accommodate the foldable helmet every time they travel, which is cumbersome and inconvenient in use. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a bag with an externally attached helmet. This bag can wrap the folded helmet on its outer side as a decorative cover, which is not only convenient for carrying the helmet, but also does not occupy the storage space inside the bag. Moreover, it solves the problems that cyclists cannot quickly escape from the vehicle body after wearing the helmet and the helmet is easily soiled, which is beneficial to improving the cycling safety of cyclists and reducing the discomfort during use. The technical solution adopted is as follows:

[0007] A bag with an externally attached helmet, including a bag body, characterized in that: it further includes a foldable helmet; the foldable helmet includes a helmet main body and two buckles, and the two buckles are respectively connected to the left and right sides of the helmet main body and can be detachably connected to each other; when the foldable helmet is in a folded state, the helmet main body can wrap around the outer side of the bag body and be detachably connected to the bag body.

[0008] When in use, when it is necessary to wear a helmet for cycling, detach the foldable helmet from the bag body and restore it to the helmet state, and wear it on the cyclist's head to play a protective role; after the cycling is over, wrap the helmet main body of the foldable helmet around the outer side of the bag body and connect the helmet main body to the bag body, which is convenient for carrying the foldable helmet. This bag with an externally attached helmet is not only convenient for carrying the foldable helmet, but also does not occupy the storage space inside the bag. Cyclists only need to bring this bag with an externally attached helmet every time they travel, without having to prepare another bag as in the prior art, which is convenient for traveling. Moreover, it solves the problems that cyclists cannot quickly escape from the vehicle body after wearing the helmet and the helmet is easily soiled, which is beneficial to improving the cycling safety of cyclists and reducing the discomfort during use. In addition, currently, the provider of shared electric vehicle helmets is the electric vehicle provider, rather than the using customers. The present invention changes the carrier of shared electric vehicle helmets, reduces the overall social cost, and removes the implementation resistance for the implementation of safer traffic regulations; this bag with an externally attached helmet can still be provided by the shared electric vehicle provider and provided to customers through trade-in or points gift, etc. There is no longer a helmet on the shared electric vehicle. When customers use the shared electric vehicle, they need to carry this bag by themselves. For customers, they only need to carry a bag instead of an additional helmet, so the resistance for customers to carry the helmet is reduced, thereby resolving the pain points of all parties to facilitate the implementation of safer regulations.

[0009] In a preferred embodiment, the bag body is provided with two handles arranged side by side on the left and right, and each of the two handles is provided with an adjustable lock, and the two adjustable locks can be respectively buckled and connected with the corresponding buckles of the foldable helmet. After the foldable helmet wraps around the outer side of the bag body, the two adjustable locks can be buckled and connected with the two buckles of the foldable helmet to realize the fixation of the foldable helmet.

[0010] In a more preferred embodiment, a strip-shaped opening communicating with the inner cavity of the bag body is provided at the top of the bag body, and a sealing zipper is provided on the strip-shaped opening; the two handles are respectively located on both sides of the strip-shaped opening.

[0011] The above-mentioned bag body can be a backpack, a shoulder bag, a handbag, etc. In the case where the bag body is a side-back shoulder bag or a cross-back shoulder bag, in a preferred embodiment, the bag further includes a length-adjustable shoulder strap, and both ends of the shoulder strap are connected to the front and rear ends of the bag body.

[0012] In a preferred embodiment, the helmet main body includes an elastic bottom pad and a helmet outer shell. The helmet outer shell includes a main shell trunk and two sets of shell folding edges. The main shell trunk includes a middle trunk and two side trunks respectively arranged on the front and rear sides of the middle trunk. The middle trunk and the two sets of shell folding edges are all arranged on the outer side surface of the elastic bottom pad. The two sets of shell folding edges are respectively located on the left and right sides of the main shell trunk. The left set of shell folding edges includes at least one shell folding edge arranged in sequence from the main shell trunk to the lower left edge of the helmet outer shell, and the right set of shell folding edges includes at least one shell folding edge arranged in sequence from the main shell trunk to the lower right edge of the helmet outer shell; each shell folding edge includes a plurality of folding edge units movably connected in sequence from front to back, and adjacent two folding edge units are clamped and positioned through at least one first clamping structure; the left set of shell folding edges and the part of the elastic bottom pad on the left side of the middle trunk constitute the left protection part of the helmet, and the right set of shell folding edges and the part of the elastic bottom pad on the right side of the middle trunk constitute the right protection part of the helmet; the front edges of the left protection part of the helmet and the front edges of the right protection part of the helmet are both connected to the front side trunk through a first detachable connection structure, or the front edges of the left protection part of the helmet are connected to the front edges of the right protection part of the helmet through a first detachable connection structure; the rear edges of the left protection part of the helmet and the rear edges of the right protection part of the helmet are both connected to the rear side trunk through a second detachable connection structure, or the rear edges of the left protection part of the helmet are connected to the rear edges of the right protection part of the helmet through a second detachable connection structure; when the foldable helmet is in the folded state, the helmet main body can be sleeved on the outside of the bag body from the bottom of the bag body to form a decorative outer cover of the bag body.

[0013] The above elastic bottom cushion can be made of elastic fabrics (fabrics woven with elastic yarns and having high elongation and high resilience), rubber sheets and other materials with a certain elasticity, and is used to connect the main body of the helmet shell and the two groups of folded edges of the helmet shell; the above middle main body, side main body, and folded edges of the helmet shell can be made of plastic or metal materials, with a certain thickness to ensure their strength, and are required to bear impact forces in the helmet state. When the foldable helmet needs to be folded and carried as a decorative outer cover of a bag, first untie the first detachable connection structure and the second detachable connection structure, and then untie the first clamping structure between all adjacent folded edge units of each folded edge of the helmet shell. Since the elastic bottom cushion is connected to the middle main body and each folded edge of the helmet shell, and the elastic bottom cushion is a flexible material, under the action of the elastic bottom cushion, each folded edge of the helmet shell can form a relatively flat plane and form an angle of about 90 degrees with the middle main body, so that the foldable helmet can be folded into a relatively flat sleeve bag. Then, the sleeve bag is sleeved on the outside of the bag body from the bottom of the bag body and connected and fixed to the bag body, and used as a decorative outer cover of the bag, which can make the appearance of the bag more beautiful. At the same time, it is convenient for the rider to carry the foldable helmet and does not occupy the storage space inside the bag body. When the foldable helmet needs to be restored to the helmet state for wearing and riding, after removing the sleeve bag formed by the foldable helmet from the outside of the bag body, the first clamping structure is used to clamp and position all adjacent folded edge units of each folded edge of the helmet shell, and then the helmet left protection part and the helmet right protection part are connected and fixed through the first detachable connection structure and the second detachable connection structure; at this time, two adjacent folded edge units in the folded edge of the helmet shell are firmly positioned (the folded edge units can be slightly folded), so that each folded edge of the helmet shell can form an arc surface of the helmet shell; since the elastic bottom cushion is connected to the middle main body and each folded edge of the helmet shell, under the action of the helmet shell main body and each folded edge of the helmet shell, a complete helmet shell (the helmet shell is roughly hemispherical) is formed, so that the foldable helmet can be restored to the helmet state. After the rider wears it on the head, the helmet is fastened by the mutual buckling of the two buckles.

[0014] In a more preferred solution, when the foldable helmet is in the folded state, the helmet shell main body is flattened and located below the bottom of the bag body, and the helmet left protection part and the helmet right protection part are flattened and located on both sides of the bag body respectively.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] The present invention can fold the helmet and wrap it outside the bag to form a decorative outer cover of the bag, which is not only convenient for carrying the foldable helmet, but also does not occupy the storage space inside the bag. The rider only needs to bring a bag with an externally attached helmet every time they travel, without having to prepare another bag as in the prior art, which is convenient for traveling. Moreover, it solves the problems that the rider cannot quickly escape from the vehicle body after wearing the helmet and the helmet is easily soiled, which is beneficial to improving the riding safety of the rider and reducing the discomfort during use. In addition, currently, the provider of shared electric vehicle helmets is the electric vehicle provider, rather than the using customer. The present invention changes the carrier of shared electric vehicle helmets, reduces the overall social cost, and removes the implementation resistance for the implementation of safer traffic regulations; such a bag with an externally attached helmet can still be provided by the shared electric vehicle provider and provided to customers through trade-in or point-giving methods. There is no longer a helmet on the shared electric vehicle. When the customer uses the shared electric vehicle, the customer needs to carry such a bag by themselves. For the customer, it is only necessary to carry a bag without having to carry an additional helmet, so the resistance for the customer to carry the helmet is reduced, thereby breaking through the pain points of all parties to facilitate the implementation of safer regulations.

[0062] Reference Figure 9, in this embodiment, the middle main body 1211 and the side main bodies 1212 are both arc-shaped and extend in the front-rear direction; the side main bodies 1212 are hinged to the corresponding ends of the middle main body 1211 through a connecting pin shaft 1213 extending in the left-right direction, and the side main bodies 1212 are in cooperation with the corresponding end faces of the middle main body 1211; a torsion spring 1214 is sleeved on the connecting pin shaft 1213, and the two ends of the torsion spring 1214 are respectively connected to or in contact with the corresponding side main body 1212 and middle main body 1211; both ends of the middle main body 1211 have a first upper end face 12111 and a first lower end face 12112, and the first lower end face 12112 is located below the first upper end face 12111 and forms an angle with the first upper end face 12111; the corresponding connecting pin shaft 1213 is located between the first upper end face 12111 and the first lower end face 12112; the end of the side main body 1212 close to the middle main body 1211 has a second upper end face 12121 and a second lower end face 12122, the second lower end face 12122 is located below the second upper end face 12121 and forms an angle with the second upper end face 12121, the second upper end face 12121 is in cooperation with the corresponding first upper end face 12111, and the second lower end face 12122 is in cooperation with the corresponding first lower end face 12112. When the foldable helmet 200 is in the folded state, the two side main bodies 1212 swing upward around the connecting pin shaft 1213 under the action of the corresponding torsion springs 1214 to a position where the side main bodies 1212 are in contact with the corresponding end faces of the middle main body 1211 (at this time, the second upper end face 12121 of the side main body 1212 is in contact with the corresponding first upper end face 12111 of the middle main body 1211 to achieve limiting), and the two side main bodies 1212 are in a position flush with or close to flush with the middle main body 1211; when the foldable helmet 200 is in the helmet state, the outer sides of the two side main bodies 1212 and the outer side of the middle main body 1211 are on the same arc surface (at this time, the second lower end faces 12122 of the two side main bodies 1212 are respectively in contact with the corresponding first lower end faces 12112 of the middle main body 1211 to achieve limiting), the torsion spring 1214 is in a compressed state, and the two side main bodies 1212 have a tendency to swing upward around the connecting pin shaft 1213.

[0063] Reference Figure 10 , Figure 11, in this embodiment, in the left helmet shell folding edge group 122 and the right helmet shell folding edge group 122, the folding edge unit 12211 of the helmet shell folding edge 1221 closest to the helmet shell main body 121 is connected to the middle main body 1211 through at least one third detachable connection structure 1224. The third detachable connection structure 1224 includes a third clamping groove 12241, a mounting groove 12242, a tension spring 12243, a connecting rod 12244, and a third clamping block 12245. The third clamping groove 12241 is provided at the edge part of the folding edge unit 12211, the mounting groove 12242 is provided on the middle main body 1211, the mounting groove 12242 corresponds to the position of the third clamping groove 12241, the connecting rod 12244 is located in the mounting groove 12242, the tension spring 12243 is provided in the mounting groove 12242, one end of the tension spring 12243 is connected to the middle main body 1211, the other end of the tension spring 12243 is connected to the first end of the connecting rod 12244, and the third clamping block 12245 is provided at the second end of the connecting rod 12244 and is in clamping cooperation with the third clamping groove 12241; the part of the folding edge unit 12211 corresponding to the third clamping groove 12241 can be separated from the elastic bottom pad 11. On the groove wall of the third clamping groove 12241 close to the elastic bottom pad 11, there is a second clamping block insertion opening 12246 for the third clamping block 12245 to insert into the third clamping groove 12241, and a connecting rod accommodation groove 12247 for accommodating the connecting rod 12244. The bottom of the third clamping groove 12241 and the second clamping block insertion opening 12246 are both communicated with the connecting rod accommodation groove 12247, and the groove opening of the third clamping groove 12241 is communicated with the second clamping block insertion opening 12246 (the groove opening size of the third clamping groove 12241 is larger than the cross-sectional size of the connecting rod accommodation groove 12247). When the foldable helmet 200 needs to be folded, the helmet shell folding edge 1221 closest to the top of the helmet main body 1 can be pulled outwards, so that each third clamping block 12245 on the middle main body 1211 is separated from the corresponding third clamping groove 12241 on the helmet shell folding edge 1221 respectively, and then the helmet shell folding edge 1221 is flipped about 90 degrees and pushed upwards; at this time, each connecting rod 12244 enters the corresponding mounting groove 1224 in the corresponding tension spring 12243 respectively, and only the third clamping block 12245 is exposed outside the middle main body 1211, reducing its exposed volume after folding. When the foldable helmet 200 needs to be unfolded into the helmet state again, each third clamping block 12245 on the middle main body 1211 can be inserted into the corresponding third clamping groove 12241 on the helmet shell folding edge 1221 closest to the top of the helmet main body 1 through the second clamping block insertion opening 12246 respectively to achieve clamping cooperation, realizing the connection between the folding edge unit 12211 of the helmet shell folding edge 1221 closest to the helmet shell main body 121 and the middle main body 1211.

[0064] In this embodiment, the helmet main body 1 further includes a buffer padding layer 13, and the buffer padding layer 13 is disposed on the inner side surface of the elastic bottom pad 11; the buffer padding layer 13 includes a plurality of buffer pads 131, and each buffer pad 131 is disposed on the inner side surface of the elastic bottom pad 11. The buffer pad 131 is made of materials such as expanded polyethylene (EPE), etc. It has a certain thickness and can generate corresponding deformation after being subjected to an external force, and can bear a certain impact force, and can play a good buffer and protection role for the head of the rider after the rider wears it.

[0065] The following briefly describes the usage method of the bag of this externally attached helmet:

[0066] When a rider needs to wear the foldable helmet 200 for cycling, first untie the connection between the helmet main body 1 and the bag body 100, and untie the connection between the two adjustable buckles 301 and the two straps 2 of the foldable helmet 200, and then remove the sleeve formed by the foldable helmet 200 from the outside of the bag body 100; subsequently, fasten and position all adjacent folding edge units 12211 between the adjacent folding edges 1221 of the helmet shell folding edge 1221 through the first clamping structure 1222, and fasten and position the second clamping structure 1223 between the folding edge units 12211 of all adjacent two helmet shell folding edges 1221 in the left helmet shell folding edge group 122 and the right helmet shell folding edge group 122, and then connect the folding edge unit 12211 of the helmet shell folding edge 1221 closest to the helmet shell main body 121 and the middle main body 1211 through the third detachable connection structure 1224; at this time, two adjacent folding edge units 12211 in the helmet shell folding edge 1221 are firmly positioned (the folding edge units 1221 can be slightly folded), so that each helmet shell folding edge 1221 can form an arc surface of the helmet outer shell 12; finally, connect and fix the left helmet protection part 1201 and the right helmet protection part 1202 of the helmet through the first detachable connection structure 123 and the second detachable connection structure 124; since the elastic bottom pad 11 is connected to the middle main body 1211 and each helmet shell folding edge 1221, under the action of the helmet shell main body 121 and each helmet shell folding edge 1221, a complete helmet outer shell 12 (the helmet outer shell 12 is generally hemispherical) is formed, and the foldable helmet 200 can be restored to the helmet state. After the rider wears it on the head, the foldable helmet 200 is fastened by the mutual buckling connection of the two straps 2, and can play a protective role for the head of the rider.

[0067] After the rider finishes the ride, first untie the first detachable connection structure 123 and the second detachable connection structure 124, then untie the third detachable connection structure 1224, so that the folding edge unit 12211 of the helmet shell folding edge 1221 closest to the helmet shell main body 121 is separated from the middle main body 1211. Then untie the first clamping structure 1222 between all adjacent folding edge units 12211 of the helmet shell folding edge 1221, and then untie the connection between all adjacent folding edge units 12211 in the helmet shell folding edge 1221. Also, untie the second clamping structure 1223 between the folding edge units 12211 of all adjacent two helmet shell folding edges 1221 in the left helmet shell folding edge group 122 and the right helmet shell folding edge group 122. At this time, since the elastic bottom pad 11 is connected to the middle main body 1211 and each helmet shell folding edge 1221, and the elastic bottom pad 11 is a flexible material, under the action of the elastic bottom pad 11, each helmet shell folding edge 1221 can form a relatively flat plane and form an angle of about 90 degrees with the middle main body 1211. At this time, the foldable helmet 200 is folded into a relatively flat sleeve bag. Then, put the foldable helmet 200 on the outside of the bag body 100 from the bottom of the bag body 100 and connect it to the bag body 100. At the same time, connect the two adjustable buckles 301 to the two straps 2 of the foldable helmet 200. At this time, the foldable helmet 200 forms a decorative outer cover of the bag body 100, making the appearance of the bag body 100 more beautiful. At the same time, it is convenient for the rider to carry the foldable helmet 200 and does not occupy the storage space inside the bag body 100. Embodiment

[0068] Reference Figure 12 、 Figure 13 , in other parts, which are the same as those in Embodiment 1, the difference is that: in this embodiment, the left helmet shell folding edge group 122 includes at least two helmet shell folding edges 1221 arranged in sequence from the helmet shell main body 121 to the lower left edge of the helmet shell 12, and the right helmet shell folding edge group 122 includes at least two helmet shell folding edges 1221 arranged in sequence from the helmet shell main body 121 to the lower right edge of the helmet shell 12; in the left helmet shell folding edge group 122 and the right helmet shell folding edge group 122, there is no connection between the folding edge unit 12211 of the helmet shell folding edge 1221 closest to the helmet shell main body 121 and the middle main body 1211 (that is, the third detachable connection structure 1224 is not provided), and there is no connection between the folding edge units 12211 corresponding to each other in two adjacent helmet shell folding edges 1221 (not clamped and positioned by the second clamping structure 1223).

[0069] The helmet shell folding edges 1221 in the left helmet shell folding edge group 122 can be arranged at intervals or closely; the helmet shell folding edges 1221 in the right helmet shell folding edge group 122 can be arranged at intervals or closely.

[0070] When the elastic bottom pad 11, the helmet shell 12 and the buffer pad 13 have relatively large material thicknesses, by reducing the connections between the helmet shell folding edges 1221 and the connections between the helmet shell folding edges 1221 and the middle main body 1211, the overall structure of the foldable helmet 200 can be simplified while ensuring that the helmet body 1 has sufficient strength, thereby reducing its production cost. Embodiment

[0071] Reference Figure 14 , in the case where other parts are the same as those in the first embodiment, the differences are as follows: The helmet body 1 further includes an inner lining headband 14 and a plurality of connecting brackets 15, and each connecting bracket 15 is installed on the inner side surface of the elastic bottom pad 11; the inner lining headband 14 is provided inside the helmet shell 12, and the inner lining headband 14 includes a left headband part 141 and a right headband part 142. The left headband part 141 and the right headband part 142 are respectively located on both sides of the helmet shell main body 121. The middle parts of the left headband part 141 and the right headband part 142 are respectively connected to at least one corresponding connecting bracket 15. The front ends of the left headband part 141 and the right headband part 142 are detachably connected (for example, by a mother-and-son buckle connection), and the rear ends of the left headband part 141 and the right headband part 142 are detachably connected (for example, by a mother-and-son buckle connection); two connecting brackets 15 with symmetrical positions form a pair of connecting brackets 15; an elastic band 16 is connected between the two connecting brackets 15 of each pair of connecting brackets 15; buffer pads (not shown in the figure) are sleeved on the outer sides of the left headband part 141 and the right headband part 142, and the buffer pads are made of elastic sponge. When a rider wears the foldable helmet 200, the inner lining headband 14 is sleeved on the outer side of the rider's head, which can make the wearing of the foldable helmet 200 stable. The buffer pads can make the rider's head comfortable to wear and can bear a certain impact force, playing a good buffering and protecting role for the rider's head; each elastic band 16 has a certain distance from the inner side of the helmet shell 12 and is used to fit the center of the rider's head; when the helmet shell 12 is folded or unfolded, since the elastic band 16 has a certain elasticity, it will not prevent the deformation of the foldable helmet 200, so it does not need to be disconnected.

[0072] In this embodiment, a long strip hole 151 is opened at the end of the connecting bracket 15, and both ends of the elastic band 16 pass through the long strip holes 151 of two connecting brackets 15 with symmetrical positions and are then sewn together.
