[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The purpose of this utility model is to provide a rear bumper and tricycle to solve the problems existing in the prior art, improve installation efficiency, and save manpower.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figures 1-2As shown, this utility model provides a rear guard bar, including a guard bar body 101, at least one mounting hole 4 on the guard bar body 101, and at least one limiting mechanism. When the mounting hole 4 is aligned with the fixing hole on the tricycle, the limiting mechanism can be mounted on the tricycle. On the one hand, mounting it on the tricycle avoids the need for installers to hold the guard bar body 101 during installation, saving manpower. On the other hand, when installers install the guard bar body 101, the limiting structure can provide a certain degree of auxiliary positioning, helping installers to align the mounting hole 4 on the guard bar body 101 with the mounting hole 4 on the tricycle.

[0027] In some embodiments, the limiting mechanism includes a fixing plate 1, which is fixedly disposed above the mounting hole 4. Fixing it above the mounting hole 4 ensures its position is clearly defined, guaranteeing that the limiting mechanism remains consistent during each installation. This provides stable limiting and assistance for the installation of the rear bumper, improving installation reliability.

[0028] It should be noted that the limiting mechanism can also be of other types, such as limiting posts. The application of limiting posts is similar to that of limiting plates. They can be mounted on tricycles, and multiple limiting posts can be set up side by side. Moreover, the length of the limiting posts or limiting plates can be adjusted as needed to ensure that they can be mounted on tricycles.

[0029] In some embodiments, multiple mounting holes 4 and limiting mechanisms are provided around the circumference of the guardrail body 101. Multiple mounting holes 4 provide more fixing points, increasing the connection points between the guardrail body 101 and the tricycle, thereby distributing the force during installation, enhancing the stability of the rear guardrail after installation, and reducing the risk of the guardrail detaching due to loosening of individual connection points. Multiple limiting mechanisms distributed around the circumference of the guardrail body 101 can limit the guardrail body 101 from multiple directions. Compared to a single limiting mechanism, this allows for more accurate determination of the guardrail body 101's position on the tricycle, improving positioning accuracy during installation, ensuring the guardrail is in the correct position after installation and meets design requirements.

[0030] In some embodiments, three limiting mechanisms are provided and fixedly installed on the left, right, and rear sides of the guardrail body 101, respectively. The left side of the guardrail body 101 is the same as the left side of the tricycle, the right side is the same as the right side of the tricycle, and the rear side is the side opposite to the forward direction of the tricycle. The limiting mechanisms on the sides and rear of the guardrail body 101 can limit the guardrail body 101 from three different directions, forming a relatively stable limiting structure. This effectively prevents the guardrail from moving or shifting in any direction during installation, ensuring the stability and accuracy of the guardrail installation. At the same time, the three limiting mechanisms do not waste materials while meeting the usage requirements.

[0031] It should be noted that the limiting mechanism can also be of other quantities, such as one on each of the left and right sides, and two or three on the rear side, which can further enhance the stability of the guardrail body 101 during and after installation.

[0032] In some embodiments, the rear bumper further includes at least one mounting plate. Each mounting plate is fixedly connected to the bumper body 101 and vertically disposed below a limiting mechanism, and the mounting plate is provided with mounting holes 4. The fixed connection between the mounting plate and the bumper body 101 increases the connection area between the bumper and the tricycle. A larger connection area can distribute the stress during installation, making the connection between the rear bumper and the tricycle more secure, improving the stability of the rear bumper during use, and reducing the possibility of loosening due to vibration, bumps, or other factors.

[0033] In some embodiments, mounting pieces are provided on both sides and the rear side of the guardrail body. The mounting pieces on both sides are first mounting pieces 2, and the mounting piece on the rear side is a second mounting piece 3. There are two first mounting pieces 2, which are respectively provided on both sides of the guardrail body 101. During installation, the first mounting pieces 2 are attached to the outer side of the rear seat 102 of the tricycle, and the second mounting pieces 3 are provided on the rear side of the guardrail body 101. During installation, the second mounting pieces 3 are attached to the inner side of the rear seat 102 of the tricycle. The first mounting pieces 2 are attached to the outer side of the rear seat 102, which can prevent the guardrail body 101 from moving inward to the rear seat 102. The second mounting pieces 3 are attached to the inner side of the rear seat 102, which can prevent the guardrail body 101 from moving outward to the rear seat 102. It is equivalent to the rear seat 102 being locked between the first mounting pieces 2 and the second mounting pieces 3, making the connection between the guardrail body 101 and the rear seat 102 more stable.

[0034] In some embodiments, each mounting plate has two mounting holes 4 arranged side by side. Two mounting holes 4 on each mounting plate mean that each mounting plate has two connection points with the tricycle, providing a stronger fixing effect compared to a single mounting hole 4. Multiple connection points can distribute the force during installation and use, reducing the risk of loosening or breakage due to excessive force at a single point, making the connection between the rear bumper and the tricycle more stable and reliable.

[0035] It should be noted that the mounting holes 4 on each mounting plate can be adjusted as needed. For example, if there is insufficient installation space, one mounting hole 4 can be set. When the weight of the guard bar body 101 is large or the safety requirements are high, the number of mounting holes 4 can be increased, such as setting three in a row. Moreover, the setting method of the mounting holes 4 can also be adjusted, such as arranging them sequentially in the column direction, or setting four mounting holes 4, with two in each row and two in each column.

[0036] In some embodiments, the mounting plate includes a limiting portion 201 and a fitting portion 202. A fixing piece 5 that fits into the mounting plate is provided on the rear seat bucket 102 of the tricycle. The limiting portion 201 is perpendicular to the fitting portion 202 and fixed horizontally to both sides of the fitting portion 202. The fitting portion 202 has mounting holes 4. The fitting portion 202 is used to fit against the outer side of the fixing piece 5, and the inner side of the limiting portion 201 can fit against the outer side of the fixing piece 5, thus restricting the left and right movement of the guardrail body in the horizontal direction. The limiting portion 201 is perpendicular to both sides of the fitting portion 202, and its inner side can fit against the outer side of the fixing piece 5. During installation, the limiting portion 201 can accurately hold the fixing piece 5, providing a clear positioning reference for the mounting plate. Installers can easily align the mounting plate with the fixing piece 5, ensuring that the mounting holes 4 on the fitting portion 202 accurately correspond to the corresponding holes on the fixing piece 5, improving installation accuracy and reducing installation errors. The combined structure of the limiting part 201 and the fitting part 202 enables multi-faceted contact and fixation between the mounting piece and the fixing piece 5. The fitting part 202 fits against the fixing piece 5, providing a planar connection, while the limiting part 201 fits against the outer side of the fixing piece 5, increasing lateral constraint. This limits and fixes the mounting piece from multiple directions, preventing movement of the mounting piece in the horizontal and vertical directions, thereby enhancing the stability of the connection between the rear guard bar and the tricycle and effectively preventing the rear guard bar from loosening or shifting.

[0037] Example 2

[0038] This utility model also provides a tricycle, including a rear seat 102 and a rear guard bar as described in Embodiment 1. A fixing plate 5 is provided on the rear seat 102, and the fixing plate 5 has fixing holes for alignment with mounting holes 4, allowing bolts to pass through. The structure of the rear guard bar mounting plate (such as the design of the limiting part 201 and the fitting part 202) cooperates with the fixing plate 5 of the rear seat 102, enabling precise positioning during installation. The limiting part 201 accurately engages the fixing plate 5, making it easier to align the mounting hole 4 with the fixing hole, reducing installation errors and improving installation efficiency.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
