Description

Technical Field

[0001] This utility model relates to the field of battery installation technology for toilet seats, and in particular to a toilet seat and its internal hinge suitable for installing batteries of various specifications. Background Technology

[0002] As the concept of low carbon gradually becomes the main theme of people's lives and work in this era, electric transportation tools are also increasing day by day. Electric bicycles, with their economic, environmentally friendly, efficient, convenient, safe, and simple characteristics, have become the preferred means of transportation for many people. Users have different needs for battery life, and these needs are usually differentiated and met by different battery specifications.

[0003] Currently, installing batteries of different specifications usually requires adjusting the space inside the seat to accommodate the batteries. Most manufacturers still use two methods: directly producing integrated dedicated containers or separate assembly containers. However, these two types of seats still have problems such as low applicability or complicated operation.

[0004] To improve the user's happiness index when purchasing a car, it is necessary to design a seat bucket mechanism that can match different battery packs. Existing electric vehicles usually use different seat bucket structures to install different batteries, which is costly, has low versatility, and is difficult to install after-sales. This patent has invented a seat bucket hinge structure that can install batteries of different capacities. The structure is simple and highly versatile, which not only reduces R&D and manufacturing costs, but also reduces after-sales costs, and has good practicality. Utility Model Content

[0005] In view of the shortcomings of the existing production technology, the applicant provides a seat bucket and an internal hinge suitable for installing batteries of various specifications. The hinge is installed on the inner wall of the seat bucket and, through its elastic reset capability, abuts against the side walls of batteries of different specifications, thereby satisfying the purpose of limiting the position of batteries of various specifications in the same seat bucket and internal structure.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A hinge suitable for mounting batteries of various sizes, adapted to the seat bucket, installed on the inner wall of the seat bucket to compensate for the gap after the battery is installed inside the seat bucket.

[0008] The hinge includes a pivot, a spring sleeved on the pivot, a fixed arm sleeved on the pivot, and a limiting arm; the fixed arm is in a constant relative position to the inner wall of the seat, the limiting arm is rotatably connected to the fixed arm, and the limiting arm is limited by the elastic restoring force of the spring or by the resistance force of the battery.

[0009] As a further improvement to the above technical solution:

[0010] The fixed arm is installed flush with the inner wall of the seat bucket, and the movement range of the limiting arm is: with the inner wall of the seat bucket as the swing reference, the swing angle range is 0-90°.

[0011] The limit arm swings to its limit when it is perpendicular to the fixed arm, at which point the limit arm applies a clamping force to the battery.

[0012] The swing end of the limiting arm is bent to form a flange, and the flange is in surface contact with the battery.

[0013] The limiting arm is also fitted with a buffer sleeve, which extends from the flange to the hinge side of the limiting arm.

[0014] The two ends of the spring extend to abut against the opposite sides of the fixed arm and the limiting arm, respectively, and the initial state of the fixed arm and the limiting arm is perpendicular to each other.

[0015] Multiple fastening points are set on the fixed arm, and the fastening points are symmetrically distributed.

[0016] An electric vehicle seat bucket with a hinge suitable for mounting batteries of various sizes includes a seat bucket body, the side wall of which is provided with a fixed bracket, and the fixed arm of the hinge is fastened to the fixed bracket.

[0017] As a further improvement to the above technical solution:

[0018] The side wall of the seat bucket is also provided with a through groove, which is used to accommodate the flanged part of the limiting arm.

[0019] At least one fixed bracket shall be installed, and at least one corresponding hinge shall also be installed.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model has a compact and reasonable structure, is easy to operate, has a simple and easy-to-install hinge structure, low cost, and high versatility; it can be installed with battery packs of different capacities for electric vehicles.

[0022] By installing the assembled hinge into the mounting position on the seat, the fixed arm of the hinge is connected to the seat. The swinging of the limiting arm adjusts the space it occupies within the seat. When the limiting arm extends laterally and points towards the battery, it occupies more space within the seat and fills the gap for battery installation. If a larger battery needs to be installed, the limiting arm is pressed down to make room for the battery.

[0023] This utility model can provide a gap compensation function by setting at least one hinge in the seat bucket according to actual needs; or by using limiting arms and buffer sleeves of different thicknesses to compensate for different gaps. Attached Figure Description

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0036] like Figures 1-8 As shown, the hinge in this embodiment, suitable for installing batteries of various sizes, is adapted to the seat bucket and installed on the inner wall of the seat bucket to compensate for the gap after the battery is installed inside the seat bucket.

[0037] The hinge 2 includes a pivot 201, a spring 202 sleeved on the pivot 201, a fixed arm 203 sleeved on the pivot 201, and a limiting arm 204; the fixed arm 203 is in a constant relative position with the inner wall of the seat, the limiting arm 204 is rotatably connected to the fixed arm 203, and the limiting arm 204 is limited by the elastic restoring force of the spring 202 or by the resistance force of the battery.

[0038] The fixed arm 203 is installed flush with the inner wall of the seat bucket, and the movement range of the limiting arm 204 is: with the inner wall of the seat bucket as the swing reference, the swing angle range is 0-90°.

[0039] The limit state of the swing arm 204 is perpendicular to the fixed arm 203, at which point the limit arm 204 applies a clamping force to the battery.

[0040] The swing end of the limiting arm 204 is bent to form a flange, and the flange is in surface contact with the battery.

[0041] A buffer sleeve 205 is also fitted on the limiting arm 204, which extends from the flange to the hinge side of the limiting arm 204.

[0042] The two ends of the spring 202 extend against the opposite sides of the fixed arm 203 and the limiting arm 204, respectively. The initial state of the fixed arm 203 and the limiting arm 204 is perpendicular to each other.

[0043] Multiple fastening points are provided on the fixed arm 203, and the fastening points are symmetrically distributed.

[0044] The electric vehicle seat bucket of this embodiment has a hinge 2 suitable for installing batteries of various specifications. It includes a seat bucket body 1, and a fixed bracket 101 is provided on the side wall of the seat bucket body 1. The fixed arm 203 of the hinge 2 is fastened to the fixed bracket 101.

[0045] A through groove is also provided on the side wall of the seat bucket body 1, which is used to accommodate the flanged part of the limiting arm 204.

[0046] At least one fixed bracket 101 shall be provided, and at least one corresponding hinge 2 shall also be provided.

[0047] The specific structure and working principle of this utility model are as follows:

[0048] The hinge 2 provided by this utility model is used to install on the inner side wall of the seat bucket. The hinge 2 is composed of a limiting arm 204 and a fixing arm 203. The limiting arm 204 and the fixing arm 203 can rotate relative to each other. By changing the included angle between the limiting arm 204 and the fixing arm 203, the size of the space occupied by the hinge 2 in the seat bucket can be changed, thereby making up for the installation gap inside the bucket of battery packs of different specifications.

[0049] Generally, one hinge 2 installed inside a seat bucket is sufficient to meet usage requirements. The two opposing swing arms of the hinge 2 make relative displacement to adjust the space occupied. If there is a practical need, two or more hinges 2 can be installed on different side walls inside a seat bucket. For example, installing one hinge 2 on two adjacent side walls can limit and hold a smaller battery pack to one of the top corners of the seat bucket.

[0050] In this embodiment, the installation of a hinge 2 is taken as an example to illustrate the working principle of using a hinge 2 to install two different specifications of battery packs.

[0051] Each hinge 2 includes a fixed arm 203 and a limiting arm 204 that are hinged to each other and sleeved on the same pivot 201. A buffer sleeve 205 is also sleeved on the pivot 201 to reduce the rigid impact on the battery pack.

[0052] In the initial state, the two spring lines of spring 202 are pressed against the two opposite sides of the fixed arm 203 and the limiting arm 204, respectively. Under the condition of no external force, the fixed arm 203 and the limiting arm 204 exhibit the following posture: Figure 1 As shown, the fixed arm 203 is fixedly installed on the side wall of the bucket body 1 in a mutually perpendicular configuration, and the limiting arm 204 extends vertically in the initial state.

[0053] like Figure 3 The diagram shows the structure of the toilet bowl 1. A fixing bracket 101 is provided on the side wall of the toilet bowl 1. The fixing bracket 101 and the fixing arm 203 are connected by a method such as... Figure 2 The rivets 102 and countersunk screws 103 shown are used for fastening.

[0054] Figure 4 This is battery pack 4, a larger type of battery pack. Place battery pack 4 into the seat body 1, as follows... Figure 5 and Figure 6 As shown in the diagram. During installation, the second battery pack 4 presses down the limiting arm 204 until the limiting arm 204 is flat against the side wall of the seat bucket 1, with the flange extending out of the through groove in the seat bucket 1. At this point, the second battery pack 4 is completely limited by the seat bucket 1.

[0055] like Figure 7 As shown, this is battery pack 3. Battery pack 3 is smaller and is placed directly inside the seat body 1. There is a gap between battery pack 3 and the seat body 1. Figure 8 As shown, the limiting arm 204 extends toward the first battery pack 3 and abuts against the first battery pack 3, completely limiting the first battery pack 3.

[0056] Because the buffer sleeve 205 fitted on the limiting arm 204 of this invention is an elastic rubber sleeve, the rubber sleeve itself also has elastic deformation compensation capability, making it suitable for battery packs of different specifications. Furthermore, the limiting arm 204 of this invention must be perpendicular to the battery pack to achieve a reliable limiting effect; if the limiting arm 204 is at an angle to the side wall of the seat bucket 1, unstable swaying and shifting are likely to occur during the force application process. By using limiting arms 204 of different sizes, it can also be applied to more battery specifications.

[0057] The advantage of this invention is that it can be applied to the installation of battery packs of various specifications, and can be used to match battery packs of different capacities in electric vehicles.

[0058] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
