Description

Technical Field

[0001] The present application relates to the technical field of transportation tools, and in particular to a scooter frame and a scooter. Background Art

[0002] As a means of transportation, scooters can be used to transport materials and personnel, thereby reducing manual labor. The safety of scooters has always been highly valued by people. To ensure the safety performance of scooters, the structural strength of each part of the scooter must meet the usage requirements, especially the scooter frame.

[0003] The scooter's frame includes a head tube for mounting the steering assembly. The head tube is usually fixed to the front end of the frame via a connecting beam. When the scooter is impacted while driving, the impact will first act on the head tube, so the head tube is subjected to a greater impact force.

[0004] In related technologies, in order to ensure user comfort, the angle between the head tube and the connecting beam is usually less than 130°. As a result, the handlebar stem is too tilted in the vertical direction, and the stress is too concentrated at the intersection of the head tube and the connecting beam. When the head tube is subjected to a large impact force, the connection between the head tube and the connecting beam is prone to breakage, which in turn has an adverse impact on the safety of the scooter. Utility Model Content

[0005] In view of this, the purpose of this application is to propose a scooter frame and a scooter, which, on the basis of satisfying the user's comfort, disperses the force between the stressed head tube and the connecting beam, improves the service life, and solves the problem of scooter safety.

[0006] Based on the above objectives, the first aspect of the present application provides a scooter frame, comprising: a bracket body; a connecting beam connected to the bracket body, at least one end of the connecting beam extending out of the bracket body; a head pipe connected to the end of the connecting beam extending out of the bracket body, the head pipe being used to connect to a steering assembly of the scooter, and the steering assembly being capable of pivoting around the axis of the head pipe; wherein the angle α formed by the axis of the head pipe and the axis of the connecting beam is greater than 135° and less than or equal to 140°.

[0007] Optionally, the angle α is 136°, 137° or 140°.

[0008] Optionally, the connecting beam and the head pipe are an integral structure; or, the connecting beam and the head pipe are separate structures that are fixedly connected.

[0009] Optionally, the angle γ formed between the axis of the head pipe and the vertical direction is greater than or equal to 11° and less than 20°.

[0010] Optionally, the angle γ is 11°, 14° or 19°.

[0011] Optionally, a connecting surface is formed on the top of the bracket body, and the head pipe is connected to the connecting surface through the connecting beam; the angle β formed by the connecting surface and the axis of the connecting beam is 115° to 119°.

[0012] Optionally, the angle β is 115°, 117° or 119°.

[0013] Optionally, the angle α is negatively correlated with the angle β.

[0014] Optionally, the connecting beam and the bracket body are an integral structure; or, the connecting beam and the bracket body are separate structures that are fixedly connected.

[0015] Optionally, the portion of the connecting beam connected to the head pipe is inclined toward the front end of the bracket body along the length direction of the bracket body.

[0016] Based on the same inventive concept, the second aspect of the present application further provides a scooter, comprising the scooter frame as described in the first aspect.

[0017] Optionally, the steering assembly includes a front fork, a front wheel assembly, a handlebar assembly and a seat tube assembly, the front fork is located below the head tube and is pivotally connected to the head tube, the front wheel assembly is mounted on the front fork, the seat tube assembly is located above the head tube, the top end of the seat tube assembly is connected to the handlebar assembly, and the bottom end of the seat tube assembly is connected to the front fork.

[0018] Optionally, along the length direction of the bracket body, one end of the bracket body away from the connecting beam is connected to a rear wheel assembly; a connecting surface is formed on the top of the bracket body, and at least a portion of the area of ​​the connecting surface between the connecting beam and the rear wheel assembly forms a footrest area for carrying passengers.

[0019] As can be seen from the foregoing, the scooter frame and scooter provided by the present application, by limiting the angle α between the axis of the head tube and the axis of the connecting beam to a range greater than 135° and less than or equal to 140°, can disperse the forces acting on the connection between the head tube and the connecting beam when the scooter frame as a whole is subjected to stress, thereby preventing the scooter frame from fracturing at the connection between the head tube and the connecting beam during normal use or fatigue testing in a laboratory, thereby helping to improve the overall structural strength of the scooter frame and enhance safety performance. Furthermore, the steering assembly connected to the head tube can be ergonomically designed, allowing a rider on the scooter frame to operate the steering assembly more comfortably, thus meeting the user's comfort requirements.

[0027] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0028] It should be noted that the relative arrangement of the components, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application unless specifically stated otherwise.

[0032] like Figure 1 In some embodiments, the scooter frame 100 includes a frame body 110, a connecting beam 120, and a head tube 130. To prevent fracture at the connections between different components of the scooter frame 100, one approach can be to optimize the connection method, such as by increasing the strength of fasteners or optimizing welding methods. Furthermore, the relative positions of components with rod, beam, or tube structures can be optimized. This reduces the forces concentrated at the connections when the scooter frame 100 as a whole is impacted, thereby preventing fracture at the connections.

[0033] In view of this, if Figure 1 In some embodiments, the frame 100 of the scooter includes: a bracket body 110, the length direction of the bracket body 110 is defined as a first direction (eg Figure 1 The scooter is provided with a plurality of scooters, each of which is configured to include a plurality of scooters and a plurality of scooters. The scooter is provided with a plurality of scooters and a plurality of scooters. The scooter is provided with a plurality of scooters and a plurality of scooters. The scooter is provided with a plurality of scooters and a plurality of scooters. The scooter is provided with a plurality of scooters and a plurality of scooters. The scooter is provided with a plurality of scooters and a plurality of scooters. The scooter is provided with a plurality of scooters and a plurality of scooters. The scooter is provided with a plurality of scooters and a plurality of scooters. The scooter is provided with a plurality of scooters and a plurality of scooters. The scooter is provided with a plurality of scooters and a plurality of scooters.

[0034] Exemplarily, the bracket body 110 may be formed with a bearing surface (flat or curved) for carrying personnel or materials; or, be installed with a structural member (such as a seat or a clamping structure) for supporting personnel or fixing materials; or, be provided with a chamber for accommodating personnel or materials.

[0035] For example, Figure 1The connecting beam 120 can be entirely located outside the bracket body 110, in which case the end of the connecting beam 120 is connected to the surface of the bracket body 110; or, a portion of the connecting beam 120 can be located inside the bracket body 110, and the other portion extends out of the bracket body 110 from the top and / or bottom of the bracket body 110, in which case at least one side of the circumferential side wall of the connecting beam 120 is connected to the bracket body 110.

[0036] For example, the steering assembly 200 is used to control the moving direction of the scooter. The rider can control the scooter to turn left, go straight, or turn right through the steering assembly 200.

[0037] Illustratively, both the head pipe 130 and the connecting beam 120 are close to the front end of the bracket body 110 along the first direction.

[0038] For example, the angle α may be 136°, 137°, 138°, 139° or 140°.

[0039] In order to verify the connection strength of the connection between the head pipe 130 and the connecting beam 120 (hereinafter referred to as the first connection), a force simulation can be performed on the scooter frame 100. Figure 1 The applicant's research has found that applying a vertical downward force F2 to the scooter frame 100 significantly affects the connection strength at the first connection. In other words, when the scooter frame 100 as a whole is subjected to the force F2, the smaller the maximum stress at the first connection, the more reliable the connection between the head tube 130 and the connecting beam 120, and the less likely the first connection will break.

[0040] After conducting a large number of force simulations on the scooter frame 100, the applicant found that when the scooter frame 100 as a whole is subjected to the force F2, as the angle α increases, the maximum stress value at the first connection gradually decreases.

[0041] Specifically, Table 1 shows the force simulation results of the first connection corresponding to different angles α when the entire frame 100 of the scooter is subjected to the same force F2.

[0042]

[0043] As can be seen from Table 1, compared to the prior art method of setting the angle α to 127°, the maximum stress value at the first connection is significantly reduced when the angle α is set to 136° in this embodiment. Moreover, as the angle α increases, the maximum stress value at the first connection gradually decreases to a smaller value.

[0044] However, if the angle α is too large, the steering assembly 200 will be close to vertical, and the user's comfort will be reduced when operating the steering assembly 200.

[0045] In order to take into account both the user's comfort and the connection strength between the head pipe 130 and the connection beam 120 , the angle α is designed to be 135°<α≤140° in this embodiment.

[0046] The scooter frame 100 provided in the embodiment of the present application limits the angle α between the axis of the head tube 130 and the axis of the connecting beam 120 to a range greater than 135° and less than or equal to 140°. This allows the force acting on the connection between the head tube 130 and the connecting beam 120 to be dispersed when the scooter frame 100 is subjected to stress. This prevents the scooter frame 100 from fracturing at the connection between the head tube 130 and the connecting beam 120 during normal use or fatigue testing in a laboratory. This helps to improve the overall structural strength and safety of the scooter frame 100. Furthermore, it ensures that the steering assembly 200 connected to the head tube 130 is ergonomically designed, allowing a rider on the scooter frame 100 to operate the steering assembly 200 more comfortably, thus meeting the user's comfort requirements.

[0047] In some embodiments, the angle α is 136°, 137°, or 140°.

[0048] According to Table 1, when the angle α is 140°, the maximum stress value at the first connection is low, and a relatively reliable connection can be formed between the head pipe 130 and the connecting beam 120. This is suitable for scooters that require high overall structural strength of the scooter frame 100 but low comfort.

[0049] When the angle α is 136°, the steering assembly 200 is more inclined, and the user is more comfortable when using the scooter. This is suitable for scooters that require a lower overall structural strength of the scooter frame 100 and a higher level of comfort.

[0050] When the angle α is 137°, the frame 100 of the scooter can have both structural strength and comfort, making the frame 100 of the scooter more versatile.

[0051] In some embodiments, the connecting beam 120 and the head pipe 130 are an integral structure.

[0052] When the connecting beam 120 and the head pipe 130 are integrated, the connection strength and rigidity between the two can be further improved, and the assembly difficulty can be reduced and the assembly accuracy can be improved. At the same time, the overall appearance of the scooter frame 100 can be made more beautiful, which can help improve the competitiveness of the product.

[0053] In some embodiments, the connecting beam 120 and the head pipe 130 are separate structures that are fixedly connected.

[0054] For example, the head pipe 130 and the connecting beam 120 may be fixedly connected by welding, clamping, or fasteners (such as bolts).

[0055] For example, when the head pipe 130 and the connecting beam 120 are welded, a full welding process may be adopted, that is, a continuous weld mark surrounding the end of the connecting beam 120 is formed between the head pipe 130 and the connecting beam 120 .

[0056] The connecting beam 120 and the head pipe 130 are first independently molded and then fixedly connected by welding or other methods. This method helps reduce the molding cost of the connecting beam 120 and the head pipe 130, thereby helping to reduce the overall manufacturing cost of the scooter frame 100 while ensuring the connection strength between the connecting beam 120 and the head pipe 130.

[0057] like Figure 1 In some embodiments, the axis of the head tube 130 is aligned with the vertical direction (eg Figure 1 The angle γ formed by the Z direction in the image is greater than or equal to 11° and less than 20°, that is, 11°≤γ<20°.

[0058] Exemplarily, the angle γ may be 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18° or 19°.

[0059] Regarding the position of the head tube 130, in addition to considering the relative positional relationship between the head tube 130 and the connecting beam 120, the position of the head tube 130 itself must also be considered. This is because, as previously mentioned, the head tube 130 is used to mount the scooter's steering assembly 200. Therefore, the position of the steering assembly 200 is strongly correlated with the position of the head tube 130. Furthermore, since the steering assembly 200 is in direct contact with the scooter's rider, the position of the steering assembly 200 is also strongly correlated with the rider's comfort.

[0060] To this end, in this embodiment, by limiting the angle γ between the head tube 130 and the vertical direction to a range of greater than or equal to 11° and less than 20°, the position of the steering assembly 200 mounted on the head tube 130 can be made more consistent with the operating habits of the driver and passenger, conforming to ergonomic design, helping to provide the driver and passenger with a better driving experience and meet the user's comfort needs.

[0061] In some embodiments, the angle γ is 11°, 14°, or 19°.

[0062] In light of the foregoing, when the angle γ is 11°, the steering assembly 200 is closer to vertical. Accordingly, the angle α can be designed to be larger, thereby forming a more reliable connection between the head tube 130 and the connecting beam 120. This is suitable for scooters that require a high overall structural strength of the scooter frame 100 but a low level of comfort.

[0063] When the angle γ is 19°, the steering assembly 200 is more inclined, and the user is more comfortable when using the scooter. This is suitable for scooters that require a lower overall structural strength of the scooter frame 100 and a higher level of comfort.

[0064] When the angle γ is 14°, the frame 100 of the scooter can have both structural strength and comfort, making the frame 100 of the scooter more versatile.

[0065] In the prior art, the connecting beam 120 is connected to the top of the bracket body 110 at an angle of less than 110°. When the scooter frame 100 is subjected to a large force, not only is the first connection prone to fracture, but the connection between the bracket body 110 and the connecting beam 120 (hereinafter referred to as the second connection) is also prone to fracture.

[0066] In order to solve the above problem, the relative position between the connecting beam 120 and the bracket body 110 may be optimized.

[0067] like Figure 1 In some embodiments, a connecting surface 111 is formed on the top of the bracket body 110, and the head pipe 130 is connected to the connecting surface 111 through the connecting beam 120; the angle β between the connecting surface 111 and the axis of the connecting beam 120 is 115° to 119°.

[0068] For example, the angle β may be 115°, 116°, 117°, 118° or 119°.

[0069] like Figure 1 The applicant's research has found that applying a horizontal force F1 from front to back to the scooter frame 100 significantly affects the connection strength of the second connection. In other words, when the scooter frame 100 as a whole is subjected to the force F1, the smaller the maximum stress value at the second connection, the more reliable the connection between the connecting beam 120 and the bracket body 110, and the less likely the second connection will break.

[0070] After conducting a large number of stress simulations on the scooter frame 100 , the applicant found that when the scooter frame 100 as a whole is subjected to the force F1 , as the angle β increases, the maximum stress value at the second connection gradually decreases.

[0071] Specifically, Table 2 shows the force simulation results of the second connection corresponding to different angles β when the entire scooter frame 100 is subjected to the same force F1.

[0072]

[0073] As can be seen from Table 2, compared to the prior art method of setting the angle β to 110°, the maximum stress value at the second connection is significantly reduced when the angle β is set to 115° in this embodiment. Moreover, as the angle β increases, the maximum stress value at the second connection gradually decreases to a smaller value.

[0074] Likewise, if the angle β is too large, the steering assembly 200 will tend to be vertical, and the user's comfort will be reduced when operating the steering assembly 200 .

[0075] In order to take into account both the user's comfort and the connection strength between the connecting beam 120 and the bracket body 110, the angle is designed to be 115°≤α≤119° in this embodiment.

[0076] In some embodiments, the angle β is 115°, 117°, or 119°.

[0077] According to Table 2, when the angle β is 119°, the maximum stress value at the second connection is low, and a relatively reliable connection can be formed between the connecting beam 120 and the bracket body 110. This is suitable for scooters that require high overall structural strength of the scooter frame 100 but low comfort.

[0078] When the angle β is 115°, the steering assembly 200 is more inclined, and the user is more comfortable when using the scooter. This is suitable for scooters that require a lower overall structural strength of the scooter frame 100 and a higher level of comfort.

[0079] When the angle β is 117°, the frame 100 of the scooter can have both structural strength and comfort, making the frame 100 of the scooter more versatile.

[0080] As can be seen from the above, when the steering assembly 200 approaches vertical, the user's comfort will decrease when operating the steering assembly 200. If both the angle α and the angle β are larger, the steering assembly 200 will approach vertical.

[0081] In order to avoid the above situation, it is necessary to define the relationship between the angle α and the angle β.

[0082] In light of this, in some embodiments, angle α is negatively correlated with angle β. In other words, when angle α is larger, angle β can be correspondingly reduced, so that the angle between the axis of the steering assembly 200 and the connection surface 111 meets the user's comfort requirements. This also ensures the overall connection reliability of the scooter frame 100, helping to improve the overall safety performance of the scooter frame.

[0083] In some embodiments, the connecting beam 120 and the bracket body 110 are an integral structure.

[0084] The beneficial effects of the integral structure of the connecting beam 120 and the bracket body 110 are similar to the beneficial effects of the integral structure of the connecting beam 120 and the head pipe 130 , and are not described in detail here.

[0085] In some embodiments, the connecting beam 120 and the bracket body 110 are separate structures that are fixedly connected.

[0086] The beneficial effects of the split structure in which the connecting beam 120 and the bracket body 110 are fixedly connected are similar to the beneficial effects of the split structure in which the connecting beam 120 and the head pipe 130 are fixedly connected, and are not repeated here.

[0087] like Figure 1 In some embodiments, the portion of the connecting beam 120 connected to the head pipe 130 is inclined toward the front end of the bracket body 110 along the first direction.

[0088] Designing the connecting beam 120 to be inclined toward the front end of the bracket body 110 can reduce the space above the connecting surface 111 occupied by the connecting beam 120 and the head pipe 130, which helps to ensure that the connecting surface 111 has sufficient space for people or supplies.

[0089] Based on the same inventive concept and in combination with the description of the scooter frame 100 of each of the above embodiments, this embodiment provides a scooter having the corresponding technical effects of the scooter frame 100 of each of the above embodiments, which will not be described in detail herein.

[0090] like Figure 1 and Figure 2 This embodiment provides a scooter, including the scooter frame 100 as described in the above embodiments.

[0091] Specifically, such as Figure 1 and Figure 2In some embodiments, the steering assembly 200 includes a front fork 210, a front wheel assembly 220, a handlebar assembly 230, and a seat tube assembly 240. The front fork 210 is located below the head tube 130 and is pivotally connected to the head tube 130. The front wheel assembly 220 is mounted on the front fork 210. The seat tube assembly 240 is located above the head tube 130. The top end of the seat tube assembly 240 is connected to the handlebar assembly 230, and the bottom end of the seat tube assembly 240 is connected to the front fork 210.

[0092] When the rider needs to turn the scooter, he or she can rotate the handlebar assembly 230 in the target direction. The handlebar assembly 230 transmits the rotational action to the front fork 210 through the seat tube assembly 240. The front fork 210 can drive the front wheel assembly 220 to rotate in the left and right directions, thereby driving the scooter to achieve steering.

[0093] like Figure 1 In some embodiments, along the first direction, one end of the bracket body 110 away from the connecting beam 120 is connected to the rear wheel assembly 300; at least a portion of the connecting surface 111 between the connecting beam 120 and the rear wheel assembly 300 forms a footrest area for carrying passengers.

[0094] Illustratively, at least one of the front wheel assembly 220 and the rear wheel assembly 300 is a drive wheel.

[0095] For example, when one of the front wheel assembly 220 and the rear wheel assembly 300 is a driving wheel, the other is a driven wheel.

[0096] The front wheel assembly 220 and the rear wheel assembly 300 together support the frame 100 of the scooter, and when the front wheel assembly 220 and the rear wheel assembly 300 rotate, they can drive the frame 100 of the scooter to move.

[0097] When riding the scooter, the passenger can step on the footrest area to ensure the passenger's stability, and can control the scooter conveniently and comfortably through the steering assembly 200 .

[0098] It should be noted that the above description is limited to some embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recited in the claims may be performed in an order different from that described in the above embodiments and still achieve the desired results.
