[0033] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a steel frame bobsleigh chassis is provided.

[0034] Specifically, the steel-framed bobsleigh frame includes: a frame body and adjusting components 3. The frame body includes two crossbeams 1 and two longitudinal beams 2. The crossbeam 1 is connected between the two longitudinal beams 2, and the crossbeams 1 and longitudinal beams 2 form a frame structure. There are multiple adjusting components 3, each of which is detachably connected to the crossbeam 1. The length direction of the adjusting component 3 is along the length direction of the crossbeam 1. At least one of the adjusting components 3 has a different mass and stiffness than the other adjusting components 3, so that the stiffness of the frame body can be changed by changing the connection between the adjusting component 3 and the crossbeam 1.

[0035] In the embodiments of this application, the frame body is a frame structure formed by connecting the crossbeam 1 and the longitudinal beam 2. The frame body is matched with a plurality of adjustment parts 3, which are detachably connected to the crossbeam 1. By replacing the adjustment parts 3 with different masses or different stiffnesses, the stiffness of the frame body can be adjusted to meet the needs of different athletes for maneuverability and steering sensitivity.

[0036] In one exemplary embodiment of this application, there are two sets of adjusting members 3, and the two sets of adjusting members 3 are connected to the two crossbeams 1 in a one-to-one correspondence. That is, each crossbeam 1 of the frame body is equipped with an adjusting member 3, and the adjusting members 3 on each crossbeam 1 are completely identical to ensure that the frame body itself is in a balanced state.

[0037] As an alternative implementation, the structure of the adjusting member 3 on each crossbeam 1 can be different, as long as the overall rigidity of the two crossbeams 1 is consistent.

[0038] In another exemplary embodiment of this application, in order to accommodate the needs of different athletes, the adjusting members 3 on the two crossbeams 1 may be inconsistent, that is, the overall stiffness of the two crossbeams 1 is different.

[0039] Furthermore, in an exemplary embodiment of this application, the stiffness of the adjusting member 3 is differentiated by creating holes of different sizes in the adjusting member 3. For example... Figure 2 As shown, the adjusting member 3 has a strip hole 31, and the length direction of the strip hole 31 extends along the length direction of the adjusting member 3. The width of the strip hole 31 on different adjusting members 3 is different.

[0040] It should be noted that the larger the hole size, the smaller the stiffness of the adjusting component 3, and the smaller the hole size, the greater the stiffness of the adjusting component 3. That is, the stiffness of the adjusting component 3 is greatest when there are no holes.

[0041] Furthermore, in order to make the stiffness adjustment of the frame body more precise and better adapt to the needs of different athletes, each adjustment component 3 is provided with multiple strip holes 31. The reference position of each strip hole 31 remains unchanged, that is, the center position of the strip hole 31 is fixed, and the width of the strip hole 31 at the corresponding position on different adjustment components 3 is different.

[0042] Specifically, the adjusting member 3 has multiple strip-shaped holes 31, which are distributed in multiple groups along the width direction of the adjusting member 3, and each group of strip-shaped holes 31 has multiple groups distributed along the length direction of the adjusting member 3. The layout between adjacent groups of strip-shaped holes 31 can be the same or different.

[0043] Furthermore, in another exemplary embodiment of this application, the stiffness of the adjusting member 3 is differentiated by adding counterweights of different masses to the adjusting member 3. Specifically, the adjusting member 3 is provided with multiple counterweights, which are evenly distributed along the length direction of the adjusting member 3, and the masses of the counterweights on different adjusting members 3 are different.

[0044] Furthermore, in order to make the stiffness adjustment of the frame body more precise and better adapt to the needs of different athletes, each adjustment component 3 is equipped with multiple counterweights. The reference position of each counterweight remains unchanged, that is, the center position of the counterweight is fixed. The width, length or thickness of the counterweights at corresponding positions on different adjustment components 3 are different.

[0045] Furthermore, the stiffness of different adjusting components 3 can be distinguished by changing a variable on the adjusting component 3, simplifying the manufacturing process of the adjusting component 3 and saving manufacturing time and cost. In the embodiments of this application, the different adjusting components 3 have the same external dimensions, only the width, length or thickness of the counterweight at the corresponding position on the different adjusting components 3 are different, or only the width of the strip hole 31 is different.

[0046] Furthermore, the adjusting component 3 encloses the outside of the crossbeam 1, thereby increasing the contact area between the adjusting component 3 and the crossbeam 1, making the connection between the two more secure, and also playing a preliminary positioning role during the connection.

[0047] In one exemplary embodiment of this application, such as Figure 3 , Figure 4 As shown, the adjusting member 3 has a through groove 32 with an opening on one side, which extends along the length of the adjusting member 3. The crossbeam 1 is located within the through groove 32. That is, the left and right sides of the adjusting member 3 form a edging 33, and the adjusting member 3 is semi-enclosed to the crossbeam 1 to prevent the adjusting member 3 from falling off the crossbeam 1. The adjusting member 3 is connected to the crossbeam 1 by screws 4.

[0048] Furthermore, such as Figure 3As shown, the adjusting component 3 has a reinforcing rib 34 on the side facing the crossbeam 1, and the reinforcing rib 34 is located between two adjacent sets of strip holes 31. The setting of the reinforcing rib 34 further enhances the rigidity of the adjusting component 3.

[0049] In another exemplary embodiment of this application, the adjusting member 3 is provided with a receiving cavity, which is disposed through the length of the adjusting member 3, and the adjusting member 3 is sleeved on the outside of the crossbeam 1 through the receiving cavity. That is, the adjusting member 3 and the crossbeam 1 are fully enclosed and connected, which further increases the firmness of the connection between the two.

[0050] Furthermore, the length of the adjusting component 3 is equal to the length of the crossbeam 1. That is, each set of adjusting components 3 has only one adjusting component 3, which simplifies the connection and assembly between the adjusting component 3 and the crossbeam 1.

[0051] As an alternative embodiment, the length of the adjusting member 3 is less than the length of the crossbeam 1, that is, each set of adjusting members 3 consists of multiple adjusting members 3, and the multiple adjusting members 3 are distributed at equal intervals along the length direction of the crossbeam 1.

[0052] Furthermore, such as Figure 2 As shown, the adjusting component 3 has a connecting hole in the middle, which can be used to connect with other accessories.

[0053] According to another specific embodiment of this application, a bobsleigh is provided, including a bobsleigh frame, which is the bobsleigh frame described in the above embodiment.

[0054] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0055] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application.

Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this invention.

[0056] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
