[0019] Compared with the prior art, the present utility model has the following advantages:

[0020] For the front floor assembly of the vehicle body described in the present utility model, support portions are respectively provided on the side brackets on both sides. While the support portions support the vehicle-mounted refrigerator, the vehicle-mounted refrigerator is connected by means of the connecting portions, so that the vehicle-mounted refrigerator can be installed stably and reliably, effectively preventing the vehicle-mounted refrigerator from shaking, which is beneficial to improving the mode and stiffness of the sub-instrument panel. When applied to a vehicle, it is beneficial to improve the mode of the vehicle. Integrating the front floor of the vehicle body and the refrigerator mounting bracket into one body can eliminate the secondary assembly in the general assembly workshop, which is beneficial to ensuring the installation accuracy and can also prevent water leakage problems, thus having good practicability.

[0021] In addition, the side bracket includes a longitudinal plate and an inclined plate. On the one hand, it is convenient to connect with the vehicle-mounted refrigerator 3, and on the other hand, it is convenient to connect with the front floor of the vehicle body. Moreover, the contact area between the inclined plate and the middle channel is relatively large, which is beneficial to improving the connection reliability between the front floor of the vehicle body and the refrigerator mounting bracket. Limiting the distance between the two longitudinal plates can reserve a gap for the vehicle-mounted refrigerator in the vehicle width direction to prevent interference between the vehicle-mounted refrigerator and the refrigerator mounting bracket during the installation process along the vehicle length direction. Limiting the contact size between the inclined plate and the middle channel is to ensure the contact area between the inclined plate and the middle channel, which is beneficial to increasing the number of solder joints and thus beneficial to improving the connection reliability between the refrigerator mounting bracket and the front floor of the vehicle body.

[0022] In addition, setting the supporting part as a supporting surface can provide stable support for the vehicle-mounted refrigerator. Limiting the distance between the supporting surface and the middle channel in the vehicle height direction is to improve the stability and reliability of the support for the vehicle-mounted refrigerator. Since the refrigerator is heavy, a smaller distance can effectively prevent the vehicle-mounted refrigerator from shaking during vehicle driving, which is beneficial to improving the vehicle's modality. Setting the connecting part as a connecting hole has a simple structure and is convenient for processing, and is also convenient for connecting with existing vehicle-mounted refrigerators.

[0023] Setting the connecting bracket as a "C" shape, the connecting bracket has a relatively high structural strength, and is beneficial to improving the overall stability and reliability of the refrigerator mounting bracket, thus facilitating the stable fixation of the vehicle-mounted refrigerator. Setting weight-reducing holes on the connecting plate can reduce the self-weight of the refrigerator mounting bracket, which is beneficial to reducing the total weight of the vehicle. Setting ventilation holes on the connecting plate is beneficial for the heat dissipation fan of the vehicle-mounted refrigerator to dissipate heat. Setting positioning parts on the side bracket and the connecting bracket can facilitate the improvement of the assembly efficiency of the side bracket and the connecting bracket, is beneficial to improving the assembly quality, and is also beneficial to quickly and accurately installing the refrigerator mounting bracket on the front floor of the vehicle body.

[0024] Another object of the present invention is to provide a vehicle, on which the above-mentioned front floor assembly of the vehicle body is provided.

[0025] For the vehicle of the present invention, by applying the aforementioned front floor assembly of the vehicle body, it is possible to prevent water leakage problems at the vehicle-mounted refrigerator installation site, and the refrigerator installation stability is relatively high, which can improve the vehicle modality performance.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] Embodiment 1

[0044] The present embodiment relates to a vehicle body front floor assembly, and more particularly to a structure that can be used to install a vehicle refrigerator 3, which does not require secondary assembly in an assembly workshop, is less likely to have water leakage problems, and has high installation accuracy.

[0045] Based on the above design concept, an exemplary structure of the vehicle body front floor assembly in the application state of this embodiment is as follows: Figure 1 As shown, a refrigerator mounting frame 2 is integrated on the front floor 1 of the vehicle body, and a vehicle refrigerator 3 is mounted on the refrigerator mounting frame 2. The structure of the front floor assembly of the vehicle body of this embodiment can be referred to Figure 2 As shown, it mainly includes a vehicle body front floor 1, and a refrigerator mounting frame 2 integrated on the vehicle body front floor 1, and the refrigerator mounting frame 2 is preferably fixed to the vehicle body front floor 1 by welding.

[0046] In this embodiment, the front floor 1 of the vehicle body and the refrigerator mounting frame 2 are integrated into an integral and non-detachable structure, which can be directly electrophoresed during the production process, eliminating the process of assembling black painted parts in the final assembly workshop and avoiding drilling and convex welding studs in the middle channel. The installation accuracy is high and water leakage at the drilling site can be effectively prevented.

[0047] In order to better understand the vehicle body front floor assembly of this embodiment, first refer to Figure 2 The structure of the front floor 1 of the vehicle body is described below. The structure of the front floor 1 of the vehicle body mentioned in this embodiment can refer to the existing structure. Figure 2 In the width direction of the vehicle, the middle portion of the vehicle body front floor 1 protrudes upward to form a middle channel, the length direction of the middle channel is along the length direction of the vehicle, and the width direction of the middle channel is along the width direction of the vehicle.

[0048] The central channel has a top surface 1011 facing the top of the vehicle body, and side surfaces 1012 located on both sides of the top surface 1011 in the width direction of the vehicle. The outer side of the side surface 1012, i.e., the side facing the outside of the vehicle, is provided with a plane lower than the top surface 1011. Both side surfaces 1012 are arranged at an angle and connected between the top surface 1011 and the planes on the corresponding sides.

[0049] Next, refer to 3 to Figure 4 The structure of the refrigerator mounting frame 2 is described. In this embodiment, the refrigerator mounting frame 2 mainly includes a side bracket 201 and a connecting bracket 202. There are two side brackets 201, which are respectively welded to the two sides of the middle channel of the front floor 1 of the vehicle body. The connecting bracket 202 is connected between the side brackets 201 on both sides. Each side bracket 201 is provided with a supporting portion 20111 and a connecting portion 20112. The supporting portion 20111 is used to support the vehicle refrigerator 3, and the connecting portion 20112 is used to connect with the vehicle refrigerator 3.

[0050] As a preferred embodiment, the side bracket 201 includes an integrally connected longitudinal plate 2011 and an inclined plate 2012, which is convenient for connection with the vehicle refrigerator 3 on the one hand, and convenient for connection with the front floor 1 of the vehicle body on the other hand. The inclined plate 2012 is gradually inclined from top to bottom away from the middle channel relative to the longitudinal plate 2011, and its inclination direction is consistent with the inclination direction of the side 1012 of the middle channel 101, so as to facilitate the welding of the inclined plate 2012 to the side 1012.

[0051] In this structure, a supporting portion 20111 and a connecting portion 20112 are provided on the longitudinal plate 2011, so that the middle channel of the inclined plate 2012 is welded and connected, which is beneficial to improving the reliability of the connection between the front floor 1 of the vehicle body and the refrigerator mounting frame 2.

[0052] As a preferred embodiment, the distance between the longitudinal plates 2011 on both sides is at least 1.5 mm larger than the dimension of the vehicle refrigerator 3 in the vehicle width direction. Thus, by limiting the distance between the longitudinal plates 2011 on both sides, a gap can be reserved for the installation of the vehicle refrigerator 3 in the vehicle width direction, which is convenient for installing the vehicle refrigerator 3 along the vehicle length direction, and can prevent the vehicle refrigerator 3 from interfering with the refrigerator mounting frame 2 during the installation process, thereby avoiding the problem of inadequate assembly. The distance should not be too small, otherwise it will affect the installation of the vehicle refrigerator 3.

[0053] As a preferred embodiment, Figure 2 and Figure 6 As shown, the contact dimension L1 between the inclined plate 2012 and the middle channel in the vehicle length direction is greater than 48 mm, and the contact dimension L2 between the inclined plate 2012 and the middle channel in the inclined direction of the inclined plate 2012 is greater than 48 mm. Here, by limiting the contact dimension between the inclined plate 2012 and the middle channel, the purpose is to ensure the contact area between the inclined plate 2012 and the middle channel, which is conducive to increasing the number of welding points and improving the connection reliability between the refrigerator mounting frame 2 and the front floor 1 of the vehicle body.

[0054] However, it should be noted that in this embodiment, L1 and L2 are defined at the same time, and four welding points can be arranged on the inclined plate 2012, so that the connection reliability between the inclined plate 2012 and the side 1012 is higher. In this embodiment, in addition to defining L1 and L2, of course, only L1 or only L2 can be defined as needed. Here, only the size in one direction is defined, and it should be appropriate to arrange more welding points, which is conducive to improving the connection reliability between the inclined plate 2012 and the side 1012.

[0055] As a preferred embodiment, the support portion 20111 includes a support surface arranged on the top of the longitudinal plate 2011, and the vehicle refrigerator 3 has an overlapping portion that can be overlapped on the support surface, so that the refrigerator mounting frame 2 can provide stable support for the vehicle refrigerator 3.

[0056] As a preferred embodiment, the distance between the support surface and the top surface 1011 of the middle channel in the vehicle height direction is less than or equal to 120 mm. Limiting the position of the support surface in this way makes the refrigerator mounting bracket 2 particularly suitable for mounting the in-vehicle refrigerator 3 with the compressor placed below, and at the same time is to improve the stability and reliability of the support for the in-vehicle refrigerator 3. The maximum value of the specifically limited distance is 120 mm because the self-weight of the refrigerator is about 40 catties, the items it contains are about 10 catties, and the total weight is about 50 catties. The overall weight is relatively heavy. A smaller distance can effectively prevent the in-vehicle refrigerator 3 from shaking during vehicle driving, which is beneficial to improving the vehicle's modality.

[0057] As a preferred embodiment, the aforementioned connecting parts 20112 all include connecting holes provided on the longitudinal plates 2011. The structure is simple and convenient for processing. Each longitudinal plate 2011 is connected to the in-vehicle refrigerator 3 through connecting pieces such as bolt pairs passing through the connecting holes. Adopting this detachable connection method facilitates the installation and disassembly of the in-vehicle refrigerator 3.

[0058] In this embodiment, two connecting holes are provided on each longitudinal plate 2011, and the two connecting holes are arranged at intervals in the vehicle height direction to facilitate the stable fixation of the in-vehicle refrigerator 3. It should be noted that the number of connecting holes can of course also be other values, such as three or four. However, it should be noted that when the number of connecting holes is other values, they should be arranged at intervals as much as possible in the vehicle height direction to improve the reliability of the fixation of the in-vehicle refrigerator 3.

[0059] As a preferred embodiment, the connecting bracket 202 is in a "C" shape. With this setting, the structural strength of the connecting bracket 202 is relatively high. Specifically speaking, referring to Figure 5 As shown, the connecting bracket 202 includes a cross plate 2021 and connecting plates 2022 connected to both sides of the cross plate 2021. The connecting bracket 202 is connected to the corresponding longitudinal plate 2011 through the connecting plates 2022, which is beneficial to improving the overall stability and reliability of the refrigerator mounting bracket 2, and thus is beneficial to stably fixing the in-vehicle refrigerator 3.

[0060] As a preferred embodiment, the connecting plate 2022 is provided with an opening 20221. The opening 20221 is used for weight reduction or ventilation. Here, setting the opening 20221 for weight reduction can reduce the self-weight of the refrigerator mounting bracket 2, which is beneficial to reducing the total weight of the vehicle and saving costs. And setting the opening 20221 for ventilation on the connecting plate 2022 is beneficial to the heat dissipation fan of the in-vehicle refrigerator 3 for heat dissipation, and also has the effects of weight reduction and cost saving.

[0061] In this embodiment, there are three openings 20221, all of which are strip-shaped holes, and the length directions of the three strip-shaped holes all extend along the width direction of the vehicle. The three openings 20221 can reduce weight and provide ventilation. However, it should be understood that it is also possible to provide openings 20221 that can only reduce weight.

[0062] As a preferred embodiment, at least one of the side bracket 201 and the connecting bracket 202 is provided with a positioning portion, specifically including the first positioning portion 2013 and the second positioning portion 2023 described below, and the positioning portion is used to cooperate with external tooling to limit the installation position of the refrigerator mounting frame 2 on the front floor 1 of the vehicle body.

[0063] In this embodiment, the side bracket 201 is provided with a first positioning portion 2013, and the first positioning portion 2013 is used to cooperate with an external tooling to limit the installation position of the side bracket 201 on the front floor 1 of the vehicle body. In this embodiment, the first positioning portion 2013 is specifically a positioning hole provided on the longitudinal plate 2011, and the longitudinal plates 2011 of the two side brackets 201 are both provided with positioning holes, and the positioning holes are specifically circular holes, which are convenient for assembly with the connecting bracket 202 on one hand, and convenient for installation of the refrigerator mounting frame 2 on the front floor 1 of the vehicle body on the other hand.

[0064] The connecting bracket 202 is provided with a second positioning portion 2023, which is used to cooperate with an external tooling to limit the installation position of the side bracket 201 on the front floor 1 of the vehicle body. In this embodiment, the second top position portion is specifically two positioning holes provided on the connecting plate 2022. Both positioning holes are circular holes with a large diameter and a small diameter. The large diameter circular hole is used as an auxiliary positioning hole, and the small diameter circular hole is used as a main positioning hole. On the one hand, it is convenient to assemble with the side bracket 201, and on the other hand, it is convenient to install the refrigerator mounting frame 2 on the front floor 1 of the vehicle body.

[0065] In the above structure, the first positioning portion 2013 and the second positioning portion 2023 are provided, which can improve the efficiency of assembling the side bracket 201 and the connecting bracket 202, improve the assembly quality, and facilitate the quick and accurate installation of the refrigerator mounting frame 2 on the front floor 1 of the vehicle body. In addition, the first positioning portion 2013 and the second positioning portion 2023 can use positioning holes or positioning columns. The shape of the positioning hole can be a circular hole or other shapes, such as a square hole, a bar hole, etc.

[0066] As a preferred embodiment, the edge of the side bracket 201 is provided with a first flange. For example, in this embodiment, both sides of the inclined plate 2012 are provided with a first flange, and both sides and the top of the longitudinal plate 2011 are also provided with a first flange. The first flange on the longitudinal plate 2011 and the first flange on the inclined plate 2012 on the same side of the side bracket 201 are connected together to improve the structural strength of the side bracket 201. It is worth mentioning that the aforementioned support portion 20111 is provided on the first flange on the top of the longitudinal plate 2011.

[0067] As a preferred embodiment, a second flange is provided on the edge of the connecting bracket 202, specifically, a second flange is provided on the upper and lower sides of the transverse plate 2021 and the connecting plate 2022, and the second flange on the transverse plate 2021 located on the same side of the connecting bracket 202 is connected together with the second flange on the connecting plate 2022, which can better improve the structural strength of the connecting bracket 202.

[0068] In the above structure, flanges are provided on both the side bracket 201 and the connecting bracket 202 , so that the refrigerator mounting frame 2 has a higher structural strength. However, it is also feasible to provide flanges only on the side bracket 201 or only on the connecting bracket 202 .

[0069] In the height direction of the vehicle, the connection bracket 202 in this embodiment is arranged close to the top surface 1011 to facilitate the arrangement of the vehicle refrigerator 3. In addition, according to the actual structure of the refrigerator, the height of the connection bracket 202 can be adjusted as needed.

[0070] Finally, it should be noted that in the present embodiment, both the side bracket 201 and the connecting bracket 202 can be formed by cold stamping, which has a simple structure and is easy to form. The connecting bracket 202 plays a role of lateral support, and the side bracket 201 and the connecting bracket 202 are integrated into an integrated structure by welding technology, which is beneficial to improving the mode and stiffness of the whole vehicle, can achieve the improvement and integration of installation accuracy, and is beneficial to cost saving.
